| E2fsprogs 1.42.2 (March 27, 2012) |
| ================================= |
| |
| The resize2fs program uses much less CPU and is much faster for very |
| large file systems. (Addresses Debian Bug: #663237) |
| |
| The seti and freei commands in debugfs can now take an optional length |
| argument to set and clear a contiguous range of inodes. |
| |
| E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we |
| plan to remove support for it from the kernel file system driver. It |
| really wasn't very useful and was causing more problems than it |
| solves. Since e2fsck will complain if inodes that should have |
| EOFBLOCKS_FL do not have the flag set, we are going to remove this |
| check from e2fsprogs first, and then only remove the flag from the |
| kernel much later. |
| |
| The mke2fs program can now use direct I/O via "mke2fs -D". This will |
| slow down the mke2fs, but it makes it more polite on a loaded server |
| by limiting the amount of memory that gets dirtied by mke2fs when it |
| is using buffered I/O. |
| |
| E2fsck was needlessly closing and re-opening the file system as a side |
| effect of adding Multiple Mount Protection (MMP). This isn't |
| necessary for non-MMP file systems, so drop it. |
| |
| Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we |
| can more easily diagnose memory allocation failures caused by |
| insufficient memory. E2fsck will now abort if there are memory |
| allocation failures when the file system is initially opened and |
| during the block group descriptor checks. (Addresses Google Bug: |
| #6208183) |
| |
| If there are incorrect block group checks, e2fsck will now report the |
| incorrect and corrected checksum values. |
| |
| The e2fsck progam can now write log files containing the details of |
| the problems that were found and fixed directly, via configuration |
| parameters in /etc/e2fsck.conf. |
| |
| Added the ability to limit the number of messages reported by e2fsck |
| for a given problem type. This avoids a potential bottleneck if there |
| is a serial console which can cause a boot sequence to take a long |
| time if e2fsck needs to report many, many file system errors. |
| |
| The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause |
| them to use much less memory for large file systems. |
| |
| The dumpe2fs program will now print the expected block group checksum |
| if it is incorrect. This helps to diagnose problems caused by |
| incorrect block group checksums. |
| |
| E2fsck now checks for extents with a zero length, since the kernel |
| will oops if it comes accross such a corrupted data structure. (See |
| https://bugzilla.kernel.org/show_bug.cgi?id=42859) |
| |
| E2fsck has a number of bugs relating to discard that have been fixed. |
| (1) Fixed a bug which could cause e2fsck to discard portions of the |
| inode table which were actually in use. (2) E2fsck will now avoid |
| using discard if the block device doesn't zero data on discard, since |
| otherwise this could cause problems if the file system gets corrupted |
| in the future. (3) E2fsck will now avoid using discard when it is run |
| in read-only mode. (4) Fixed a bug which caused e2fsck to not issue |
| discards in the last block group. |
| |
| E2fsck's CPU utilization in pass 5 has been optimized, which will |
| speed up e2fsck slightly. |
| |
| E2image will now skip copying uninitialized bitmap and inode table |
| blocks. |
| |
| Fixed mke2fs -S so it does not corrupt the first block group's |
| information. |
| |
| E2fsck will now check the new sysfs interface to determine if we are |
| using the battery or AC mains. (Addresses SourceForge Bug: #3439277) |
| |
| Updated/fixed various man pages. (Addresses Debian Bug: #665427) |
| |
| Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885) |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fixed various portability issues for non-Linux systems, particularly |
| MacOS X, as well as Linux systems running with the just-released glibc |
| 2.15. |
| |
| Fix file descriptor leak in ext2fs_close() if the file system with |
| uninit_bg is opened read/only with a backup superblock. (Addresses |
| SourceForge Bug: #3444351) |
| |
| Fixed an invalid return in a non-void function in the quota code. |
| (Addresses SourceForge Bug: #3468423) |
| |
| Fixed the debian rules file so that the calls to dpkg-buildflags works |
| when the shell is dash. |
| |
| The debian package build now uses V=1 so that there is more |
| information about potential build failures in debian buildd logs. |
| |
| If the uninit flags get cleared by functions such as |
| ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the |
| superblock is marked dirty and the block group descriptor checksum is |
| updated if necessary. |
| |
| The debian rules file will now try to load debian/rules.custom of it |
| exists. This flie can skip various builds for speed reasons if there |
| is no need for the e2fsck-static or udeb packages. Available |
| customizations in the rules file includes SKIP_STATIC=yes, |
| SKIP_BF=yes, and SKIP_DIETLIBC=yes. |
| |
| In addition, if the file misc/mke2fs.conf.custom.in exists in the |
| source tree, it will be used instead of the standard misc.conf file in |
| the upstream sources. This makes it easier for Debian-derived systems |
| to distribute a custom mke2fs.conf file without having to worry about |
| merge issues if future versions of e2fsprogs makes changes in the |
| upstream default version of mke2fs.conf. |
| |
| |
| E2fsprogs 1.42.1 (February 17, 2012) |
| =================================== |
| |
| The mke2fs and e2fsck now use significantly less memory when creating |
| or checking very large file systems. This was enabled by adding |
| extent-based bitmaps which are stored using a red-block tree, since |
| block and inode allocations tend to be contiguous. |
| |
| The command mke2fs -S is used as a last ditch recovery command to |
| write new superblock and block group descriptors, but _not_ to destroy |
| the inode table in hopes of recovering from a badly corrupted file |
| system. So if the uninit_bg feature is enabled, mke2fs -S will now |
| set the unused inodes count field to zero. Otherwise, e2fsck -fy |
| after using mke2fs -S would leave the file system completely empty. |
| |
| Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also |
| honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has |
| installed an mke2fs binary using that name. |
| |
| The usage and help messages for the -G, -t and -T options in mke2fs |
| have been fixed. |
| |
| If e2fsck needs to use the backup group descriptors, the |
| ext2fs_open2() function clears the UNINIT bits to ensure all of the |
| inodes in the file systems get scanned. However, the code which reset |
| the UNINIT flags did not also recalculate the checksum, which produced |
| many spurious (and scary) e2fsck messages. This has been fixed by |
| resetting cheksums when the UNINIT bits are cleared. |
| |
| Relax a check in e2fsck which required that the block bitmap to be |
| initialized when the inode bitmap is in use. This will allow us to |
| eventually eliminate code from the kernel which forcibly initialized |
| the block bitmap when the inode bitmap is first used, requiring an |
| extra journal credit and disk write. (Addresses Google Bug: #5944440) |
| |
| Make sure rdebugfs (which may be installed setuid or setgid disk) does |
| not honor environment variables if euid != uid or egid != gid. |
| |
| Debugfs's ncheck command has been optimized and now is much more |
| robust with faced with corrupted file systems. The ncheck command |
| also now has a -c option which will verify the file type information |
| in the directory entry to see if matches the inode's mode bits. This |
| is extremely useful when trying to use debugsfs to determine which |
| parts of the file system metadata can be trusted. |
| |
| E2image will try to use ftruncate64() to set the i_size for raw |
| images, instead of writing a single null byte. This avoid allocating |
| an extra block to the raw image, for those file systems and/or |
| operating systems that support this. (Linux does.) In addition, fix |
| a logic bug that caused the file to not be properly extended if the |
| size of the last hole was exactly an multiple of a megabyte. |
| |
| Fixed a bug in resize2fs where for 1k and 2k file systems, where |
| s_first_data_block is non-zero, this wasn't taken into account when |
| calculate the minimum file system size for use with the -M option. |
| |
| Fixed the badblocks program to honor the -s flag when in read-only -t |
| mode. (Addresses Debian Bug #646629) |
| |
| Update Czech, Dutch, French, Polish, and Sweedish translation from the |
| Translation Project. |
| |
| Fixed various Debian Packaging issues so that dpkg-buildflags is used |
| if present, which allows e2fsprogs to be built with security hardening |
| flags. (Addresses Debian Bugs: #654457) |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps. |
| This was only an issue for programs compiled against e2fsprogs 1.41 |
| that manipulate bitmaps directly. (Addresses Sourceforge Bugs: |
| #3451486) |
| |
| The libext2fs library now uses sysconf() to fetch the page size, instead |
| of the deprecated getpagesize(). |
| |
| The ext2fs_get_pathname() function will return a partial path if an a |
| directory in the path is not a directory, displaying it as an inode |
| number in angle brackets instead of giving up and displaying an error. |
| This is much more helpful when a user is trying to debug a corrupted |
| file system. |
| |
| Codepoints for the RO_COMPAT_REPLICA feature has been reserved. |
| |
| Added a new library function, ext2fs_file_get_inode_num(), for use by |
| fuse2fs. |
| |
| Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a |
| file, it actually works. |
| |
| The block iterator now properly honors the BLOCK_ABORT flag for |
| extent-based flags. Previously, it didn't, which generally made code |
| be less efficient, but it could cause bugs in ext2fs_link(), for |
| example, by causing it to insert multiple directory entries. |
| |
| Fixed an (harmless other than causing a compiler warning) use of an |
| uninitialized variable in e2fsck's MMP code. |
| |
| |
| E2fsprogs 1.42 (November 29, 2011) |
| ================================== |
| |
| This release of e2fsprogs has support for file systems > 16TB. Online |
| resize requires kernel support which will hopefully be in Linux |
| version 3.2. Offline support is not yet available for > 16TB file |
| systems, but will be coming. |
| |
| This release of e2fsprogs has support for clustered allocation. This |
| reduces the number of block (now cluster) bitmaps by allocating and |
| deallocating space in contiguous power-of-2 collections of blocks, |
| which are called clustered. This is a file system level feature, |
| called 'bigalloc', which must be enabled when the file system is |
| initially formatted. It is not backwards compatible with older |
| kernels. |
| |
| Added support for the Multi-Mount Protection (MMP) feature. |
| |
| E2fsck more efficiently uses scratch files for really big file |
| systems. (This is a feature that has to be turned on explicitly; see |
| [scratch_files] in the e2fsck.conf man page.) |
| |
| Fix a bug in e2fsck where if the free blocks and inodes counts are |
| incorrect, e2fsck would fix them without printing an error message. |
| This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without |
| any explanation of what was fixed. |
| |
| E2fsck will no longer attempt to clone an extended attribute block in |
| pass1b handling if the file system does not support extended |
| attributes. |
| |
| E2fsck will be more careful accidentally asking the user to continue |
| if the file system is mounted, so that an escape sequence won't cause |
| a false positive. (Addresses Debian Bug: #619859) |
| |
| E2fsck now uses less cpu time in pass 5 when large portions of the |
| bitmaps are uninitialized. |
| |
| E2fsck will no longer segault when a corrupted file system has a bad |
| extent, and removing it leads to a block needing to be deallocated. |
| (Addresses SourceForge Bug: #2971800) |
| |
| E2fsck will catch termination signals (segfaults, bus errors, sigfpe) |
| and print debugging information to make it easier to find potential |
| problems. |
| |
| E2fsck will check to see if the bad block inode looks insane, and will |
| skip trying to use if it certain fields which should be zero look |
| non-zero. This is to avoid a corrupted bad block inode causing e2fsck |
| to get confused and do more harm than good. |
| |
| If e2fsck modifies certain superblock fields which the kernel doesn't |
| look at, it will now mark the superblock as dirty without marking the |
| file system as changed. This avoids signalling the init scripts that |
| a reboot is necessary, since the kernel isn't going to look at those |
| fields, so it won't care if they have been changed. |
| |
| Fixed a bug in the libext2fs library (in the binary search routine of |
| the icount abstraction) that could (very, very rarely) cause e2fsck to |
| die in the middle of pass 1 or pass 2 processing. |
| |
| E2fsck will not try to do a discard operation if the -n option was |
| specified on the command line. |
| |
| E2fsck now supports an extended "discard" option which will cause |
| e2fsck to attempt discard all unused blocks after a full, successful |
| file system check. |
| |
| E2fsck will check for the bad block inode to make sure it looks sane |
| before trusting it, to avoid causing more harm than good to the file |
| system. |
| |
| E2fsck now returns additional status bits in its exit code if it |
| aborts early in the e2fsck run. |
| |
| E2fsck now correctly calculates the maximum file size in the case of |
| the huge_file file system feature enabled without extents. |
| |
| The mke2fs and e2fsck programs now tries to use the punch hole command |
| as a "discard" when operating on normal files. |
| |
| The e2image program now supports the qcow2 format, which is a more |
| efficient way of capturing file system dumps. |
| |
| Mke2fs now supports the [devices] stanza in mke2fs.conf which allows |
| per-device defaults to be specified in the configuration file. |
| |
| Mke2fs now supports the reserved_ratio relation in the [defaults] and |
| [fs_types] section in mke2fs.conf. |
| |
| Mke2fs now creates extent-mapped directories for the root and |
| lost+found directories. |
| |
| Mke2fs will skip zero'ing the journal if the extended option |
| "lazy_journal_init" is specified. This can save a lot of time, but it |
| does add a small amount of risk if the system crashes before the |
| journal is overwritten entirely once. It is epsecially useful for |
| testing. |
| |
| Mke2fs will now create file systems that enable user namespace |
| extended attributes and with time- and mount count-based file |
| system checks disabled. |
| |
| Mke2fs will not set a stride or strip size of one block based on block |
| device attributes obtained from sysfs. |
| |
| Mke2fs now displays a progress report during the discard process. |
| |
| Mke2fs now handles extreme file system parameters correctly which |
| previously caused the inodes per group to drop below 8, leading to a |
| segfault. (The inodes per group must be a multiple of 8, but the code |
| didn't correctly deal with an inodes per group count less than 8.) |
| |
| Mke2fs and tune2fs previously would give an error if the user tried |
| setting the stride and stripe-width parameters to zero; but this is |
| necessary to disable the stride and stripe-width settings. So allow |
| setting these superblock fields to zero. (Addresses Google Bug: |
| #4988557) |
| |
| Mke2fs now gives a warning if the auto-detected block size exceeds the |
| system's page size. |
| |
| If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which |
| is the default), mke2fs will now set the s_max_mnt_count superblock |
| field to -1, instead of 0. Kernels older then 3.0 will print a |
| spurious message on each mount then they see a s_max_mnt_count set to |
| 0, which will annoy users. (Addresses Debian Bug: #632637) |
| |
| The default mke2fs.conf now has entries for "big" and "huge", which |
| are needed for very big file systems. |
| |
| The resize2fs program now has support for a new online resize ioctl |
| that can support file systems > 16TB, once it arrives in v3.x kernels. |
| |
| Fixed bug which caused resize2fs to fail when shrinking an empty file |
| system down to its minimal size. (Addresses Sourceforge Bug #3404051) |
| |
| Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667) |
| |
| Allow tune2fs to remove external journals if the device can not be |
| found. |
| |
| Debugfs's icheck will now correctly find inodes which use the |
| searched-for block as an extended attribute block. |
| |
| Debugfs now has a new "punch" command which remove blocks from the |
| middle of an inode. |
| |
| Debugfs now has a new "e2freefrag" command which analyzes the free |
| space fragmentation of the file system, using the same code as the |
| e2freefrag program. |
| |
| Debugfs now has a "filefrag" command which displays information about |
| a file's fragmentation. |
| |
| Add support to build a metadata-only, read-only, stripped-down version |
| of debugfs called rdebugfs. |
| |
| Fixed a potential stack overrun bug in debugfs. |
| |
| The badblocks program now correctly recovers from I/O errors when |
| direct I/O is being used. The badblocks command now also supports a |
| -B option which forces the use of buffered I/O, and the -v option will |
| provide a more detailed breakdown of read, write, and failed |
| comparison errors. |
| |
| Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl. |
| |
| Added support for journals larger than 2GB. |
| |
| Support using both hard links and symlinks when installing e2fsprogs. |
| |
| Add overflow checking to tune2fs -i's fsck interval, which must fit in |
| a 32-bit field. |
| |
| The debugfs command now has a new 'blocks' command which prints out |
| data blocks of a particular inode in a format which is useful for |
| scripting. |
| |
| Filefrag will report 0 extents correctly in verbose mode. (Addresses |
| RedHat Bugzilla: #653234) |
| |
| Filefrag has been fixed so its -v report prints the correct expected |
| block number (previously there had been an off-by-one error). In |
| addition, it will now display the number of contiguous extents when -v |
| is not specified. This makes it consistent with the number of extents |
| printed when the -v option was specified. In addition, the number of |
| contiguous extents is far more interesting/useful than the number of |
| physical extents for very large files. (Addresses Debian Bug: |
| #631498, #644792) |
| |
| Logsave's usage message has been fixed. (Addresses Debian Bug: |
| #619788) |
| |
| Avoid an infinite loop in ext2fs_find_block_device() if there are |
| symlink loops in /dev caused by a buggy udev. |
| |
| Added a useful "fallocate" program to the contrib directory. |
| |
| Fixed an ABI compatibility problem in libext2fs which broke the dump |
| program. Also added back some macros which dump needed so it could |
| compile against the latest version of ext2_fs.h (Addresses Debian Bug: |
| #636418) |
| |
| Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses |
| Debian Bug: #641667) |
| |
| Added internationalization support for libcom_err error table strings. |
| |
| Fixed various spelling mistakes found in various output strings found |
| by I18N translators. |
| |
| Update translations: French, Chinese, Germany, Indonesian, Swedish, |
| Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985, |
| #620659) |
| |
| Fixed various Debian Packaging issues. (Addresses Debian Bugs: |
| #614662, #632169, #641838, #627535, #629355) |
| |
| Updated/clarified man pages. (Addresses Debian Bugs: #639411, |
| #642193, #634883) |
| |
| Programmer's Notes |
| ------------------ |
| |
| Initial support for quota as an integrated feature, where the quota |
| files are hidden system files that are automatically maintained by |
| e2fsck is present, although disabled by default. It must be enabled |
| by using the configure option --enable-quota. |
| |
| Reserved the on-disk fields for the metadata checksum and snapshot |
| features, which are currently in development. |
| |
| The ext2fs library now has the new functions ext2fs_punch(), |
| ext2fs_get_memzero() and ext2fs_file_get_inode(). |
| |
| The ext2fs library now has support for calculating the crc32c checksum |
| (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le). |
| |
| The I/O manager now supports the discard operation. |
| |
| Reserved file system code points for new 1st class quota feature. |
| |
| Shortened the compilation lines by moving the autoconf defines to |
| a config.h header file. |
| |
| Fixed a potential free of an unitialized pointer in |
| ext2fs_update_bb_inode(). |
| |
| Fixed miscellaneous gcc -Wall and coverity warnings. |
| |
| Fixed portability issues for Mac OS X, Hurd, and FreeBSD. |
| |
| Fixed a build failure when OMIT_COM_ERR is defined. |
| |
| Improved error checking and fixed memory leaks caused by error return |
| paths. |
| |
| Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow |
| the fsync() to be skipped. |
| |
| Added a test for extent-mapped journals by mke2fs and tune2fs. |
| |
| Added a test for creating a large (over 4GB) journal using mke2fs. |
| |
| Added a test to make sure the inode size remains constant. |
| |
| The regression test script now prints the list of which tests failed. |
| |
| The regression test system now uses /tmp for its scratch files, which |
| is often a tmpfs mounted file system and hence much faster. |
| |
| The i_e2image test was fixed so it works with valgrind. |
| |
| Tests that rely on debugfs are now skipped if debugfs wasn't built. |
| |
| Fixed the dependencies for "make check" so all required dependencies |
| are built before running the gression tests. |
| |
| A link to com_err.h is installed in $(includedir) during a "make install". |
| |
| The po/*.gmo files are automatically rebuilt if they are missing or |
| out of date. This helps out Debian packaging. |
| |
| Allow ext2fs_get_memalign() to compile on systems that don't have |
| posix_memalign(). |
| |
| Fixed a namespace leak in libext2fs (tdb_null). |
| |
| |
| E2fsprogs 1.41.14 (December 22, 2010) |
| ===================================== |
| |
| Fix spurious complaint in mke2fs where it would complain if the file |
| system type "default" is not defined in mke2fs.conf. |
| |
| The resize2fs program will no longer clear the resize_inode feature |
| when the number reserved group descriptor blocks reaches zero. This |
| allows for subsequent shrinks of the file system to work cleanly for |
| flex_bg file systems. |
| |
| The resize2fs program now handles devices which are exactly 16T; |
| previously it would give an error saying that the file system was too |
| big. |
| |
| E2fsck (and the libext2fs library) will not use the extended rec_len |
| encoding for file systems whose block size is less than 64k, for |
| consistency with the kernel. |
| |
| Programming notes |
| ----------------- |
| |
| E2fsprogs 1.41.13 would not compile on big-endian systems. This has |
| been fixed. (Addresses Sourceforge Bug: #3138115) |
| |
| The ext2fs_block_iterator2() function passed an incorrect ref_offset |
| to its callback function in the case of sparse files. (Addresses |
| Sourceforge Bug: #3081087) |
| |
| Fix some type-punning warnings generated by newer versions of gcc. |
| |
| |
| E2fsprogs 1.41.13 (December 13, 2010) |
| ===================================== |
| |
| E2fsck now supports the extended option "-E journal_only", which |
| causes it to only do a journal replay. This is useful for scripts |
| that want to first replay the journal and then check to see if it |
| contains errors. |
| |
| E2fsck will now support UUID= and LABEL= specifiers for the -j option |
| (which specifies where to find the external journal). (Addresses |
| Debian Bug #559315) |
| |
| E2fsck now has support for the problems/<problem code>/force_no |
| configuration option in e2fsck.conf, which forces a problem to not be |
| fixed. |
| |
| Dumpe2fs will now avoid printing large negative offsets for the bitmap |
| blocks and instead print a message which is a bit more helpful for |
| flex_bg file systems. |
| |
| Mke2fs will now check the file system type (specified with the -t |
| option) to make sure it is defined in the mke2fs.conf file; if it is |
| not, it will print an error and abort. If the usage type (specified |
| with the -T option) is not defined in mke2fs.conf, mke2fs will print a |
| warning but will continue. (Addresses Debian Bug #594609) |
| |
| Clarified error message from resize2fs clarifying that on-line |
| shrinking is not supported at all. (Addresses Debian Bug #599786) |
| |
| Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be |
| displayed. (Addresses Debian Bug #555456) |
| |
| E2fsck will open the external journal in exclusive mode, to prevent |
| the journal from getting truncated while it is in use due to a user |
| accidentally trying to run e2fsck on a snapshotted file system volume. |
| (Addresses Debian Bug #587531) |
| |
| Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL |
| flag. |
| |
| The tune2fs program can now set the uninit_bg feature without |
| requiring an fsck. |
| |
| The tune2fs, dumpe2fs, and debugfs programs now support the new ext4 |
| default mount options settings which were added in 2.6.35. |
| |
| The e2fsck and dumpe2fs programs now support the new ext4 superblock |
| fields which track where and when the first and most recent file |
| system errors occurred. These fields are displayed by dumpe2fs and |
| cleared by e2fsck. These new superblock fields were added in 2.6.36. |
| |
| Debugfs now uses a more concicse format for listing extents in its |
| stat command. This format also includes the interior extent tree |
| blocks, which previously was missing from stat's output for |
| extent-based files. |
| |
| Debugfs has a new option, -D, which will request Direct I/O access of |
| the file system. |
| |
| Mke2fs will skip initializing the inode table if a device supports |
| discard and the discard operation will result in zero'ed blocks. |
| |
| Badblocks will now correctly backspace over UTF-8 characters when |
| displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses |
| Debian Bugs #583782 and #587834) |
| |
| E2freefrag will now display the total number of free extents. |
| |
| Resize2fs -P no longer requires a freshly checked filesystem before |
| printing the minimum resize size. |
| |
| Fixed a floating point precision error in a binary tree search routine |
| that can lead to seg fault in e2fsck and resize2fs. |
| |
| Fixed a bug in e2fsck where if both the original and backup superblock |
| are invalid in some way, e2fsck will fail going back to the original |
| superblock because it didn't close the backup superblock first, and |
| the exclusive open prevented the file system from being reopened. |
| |
| Fixed a big in e2freefrag which caused getopt parsing to fail on |
| architectures with unsigned chars. (Addresses Gentoo Bug: #299386) |
| |
| Clarified an mke2fs error message so a missed common in an -E option |
| (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1") |
| results in a more understandable explanation to the user. |
| |
| Mke2fs now displays the correct valid inode ratio range when |
| complaining about an invalid inode ratio specified by the user. |
| |
| Mke2fs now understands the extended option "discard" and "nodiscard", |
| and the older option -K is deprecated. The default of whether |
| discards are enabled by default can be controled by the mke2fs.conf |
| file. |
| |
| Mke2fs's handling of logical and physical sector sizes has been |
| improved to reflect the fact that there will be some SSD's with 8k and |
| 16k physical sectors arriving soon. Mke2fs will no longer force block |
| size to be the physical sector size, since there will be devices where |
| the physical sector size is larger than the system's page size, and |
| hence larger than the maximal supported block size. In addition, if |
| the minimal and optimal io size are not exported by the device, and |
| the physical sector size is larger than the block size, the physical |
| sector size will be used to set the Raid I/O optimization hints in the |
| superblock. |
| |
| E2fsck will now display a better, more specific error message when the |
| user enters a typo'ed device name, instead of blathering on about |
| alternate superblocks. |
| |
| Fixed various Debian Packaging Issues |
| |
| Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004, |
| #589345, #591083; Addresses Launchpad Bug: #505719) |
| |
| Update the Chinese, Chzech, Dutch, French, Germany, Indonesian, |
| Polish, Swedish, and Vietnamese translations. |
| |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fix a dependency definition for the static and profiled blkid |
| libraries which could cause compile failures in some configurations. |
| (Addresses Debian Bug: #604629) |
| |
| Add support for Direct I/O in the Unix I/O access layer. |
| |
| Fixed a memory leak in the Unix I/O layer when changing block sizes. |
| |
| Fixed minor memory leaks in mke2fs. |
| |
| Added a new function to the ext2fs library, ext2fs_get_memalign(). |
| |
| The tst_super_size test program will check to make sure the superblock |
| fields are correctly aligned and will print them out so they can be |
| manually checked for correctness. |
| |
| Fixed some makefile dependencies for test programs in lib/ext2fs. |
| |
| Reserved the feature flags and superblock fields needed for the Next3 |
| snapshot feature. |
| |
| Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and |
| EXT4_INCOMPAT_EA_INODE. |
| |
| |
| E2fsprogs 1.41.12 (May 17, 2010) |
| ================================ |
| |
| Mke2fs now gives a correct error message if the external journal |
| device is not found. (Addresses Red Hat Bug #572935) |
| |
| Resize2fs -P will now refuse to print a minimum size if the file |
| system is not clean. Previously it would go ahead and print a minimum |
| size anyway, which might not be correct, leading to user confusion. |
| |
| E2fsck now tests for extents that begin at physical block 0 and |
| rejects them as invalid. (Addresses Google Bug: #2573806) |
| |
| Fixed a bug in e2fsck which could cause it to crash when trying to |
| remove an invalid extent and the block bitmaps hadn't yet been loaded. |
| (Addresses SourceForge Bug: #2971800) |
| |
| E2fsck now will completely skip time-based checks if the system clock |
| looks insane or the option broken_system_clock is set in |
| /etc/e2fsck.conf. |
| |
| E2fsck would previously report an i_blocks corruption for a 4T file |
| created using posix_fallocate; this bug has been fixed. |
| |
| E2fsck will now correctly mark a sparse journal as invalid and will |
| delete and recreate the journal to address the problem. |
| |
| E2fsck would previously incorrectly ask the user whether she would |
| like to abort the file system check after finding a problem --- and |
| then abort regardless of the user's answer. This is annoying, and |
| has been fixed. |
| |
| E2fsck can now continue even if it fails to recreate the resize |
| inode; previously it would just abort the file system check |
| altogether. |
| |
| E2fsck could potentially remove directory entries for inodes found in |
| the unused region of the inode table; this would generally happen on |
| ext4 file systems that do not use journaling. This bug has been fixed |
| by not clearing these directory entries once it has been established |
| that bg_unused_inodes may not be trustworthy; once pass #2 has been |
| completed, e2fsck will restart the file system check from the |
| beginning, and then it will be safe to delete any directory entries |
| pointing to inodes that appear to be deleted. (Addresses Google Bug: |
| #2642165) |
| |
| E2fsck will not try to set the block group checksums if the user |
| cancels the fsck with a control-C. It's a bad idea to set the |
| checksums if e2fsck hasn't been completed, and it often results an the |
| error message, "Inode bitmap not loaded while setting block group |
| checksum info". (Addresses Launchpad Bug: #582035) |
| |
| The mke2fs program now queries the kernel for the physical as well as |
| the logical sector size, and will not allow a blocksize below the |
| logical, and will strongly encourage a blocksize at least as big as |
| the physical blocksize. This is needed for 4k sector drives that |
| emulate 512 byte sector sizes. |
| |
| Mke2fs will now allow a flex_bg size of 1. This is unusual, and |
| rarely needed, but it is a legal value. |
| |
| E2fsck will check for cases where the EOFBLOCKS_FL is set when it is |
| not needed, and offer to clear it; this is a sign of a kernel bug, but |
| more importantly, some released kernels may crash when this situation |
| is encountered on ext4 file systems. (Addresses Google Bug: #2604224) |
| |
| E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether |
| i_size is correct. (Kernels starting with 2.6.34 will set |
| EOFBLOCKS_FL.) |
| |
| The com_err library will now only output ^M (a CR character) when the |
| tty is in raw mode. |
| |
| Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish, |
| and Vietnamese translations. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs: #571247, #563487) |
| |
| |
| Programmer's Notes |
| ------------------ |
| |
| The regression test suite now uses its own mke2fs.conf file, so that |
| downstream distributions want change the mke2fs.conf file which is |
| distributed in the RPM or dpkg file, without worrying about screwing |
| up the regression test results. |
| |
| Always build namei.o so that building with configure --disable-debugfs |
| works correctly. Long-term, if we care about reduced e2fsprogs |
| builds, we need a more general solution for deciding what .o files are |
| needed for a particular build. Given that install floppies are going |
| (gone?) the way the dodo bird, we probably don't care, though. |
| (Addresses Sourceforge Bug: #2911433) |
| |
| Add configure options --enable-symlink-build and |
| --enable-symlink-install, which allow e2fsprogs be built using |
| symlinks instad of hard links, and to be installed using symlinks |
| instead of hard links, respectively. It is useful when the file |
| system where the build is taking place, or the file system where |
| e2fsprogs is installed, can't handle hard links for some reason. |
| (Addresses Sourceforge Bug: #1436294) |
| |
| Fixed compile warning in mke2fs.c. |
| |
| |
| E2fsprogs 1.41.11 (March 14, 2010) |
| ================================== |
| |
| E2fsck will no longer give a fatal error and abort if the physical |
| device has been resized beyond 2**32 blocks. (Addresses Launchpad |
| Bug: #521648) |
| |
| Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows |
| the allocation status of the block <blk>. (Addresses Debian Bug: |
| #564084) |
| |
| E2fsck now prints a much more emphatic and hopefully scary message |
| when a file system is detected as mounted while doing a read/write |
| check of the filesystem. Hopefully this will dissuade users from |
| thinking, "surely that message doesn't apply to *me*" :-( |
| |
| E2fsck -n will now always open the file system read-only. We now |
| disallow certain combination of options which previously were manual |
| exceptions; this is bad because it causes users to think they are |
| smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n |
| -D" are no longer supported. (Addresses Launchpad Bug: #537483) |
| |
| In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if |
| it detected a badly aligned partition. Unfortunately, this broke some |
| distribution installation scripts, so it now just prints the warning |
| message and proceeds. (Addresses Red Hat Bug: #569021. Addresses |
| Launchpad Bug: #530071) |
| |
| Mke2fs would take a long time to create very large journal files for |
| ext4. This was caused by a bug in ext2fs_block_iterate2(), which is |
| now fixed. |
| |
| E2fsck now understands the EOFBLOCKS_FL flag which will be used in |
| 2.6.34 kernels to make e2fsck not complain about blocks deliberately |
| fallocated() beyond an inode's i_size. |
| |
| E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where |
| e2fsck -fD can corrupt non-indexed directories when are exists one or |
| more file names which alphabetically sort before ".". This can happen |
| with ext2 filesystems or for small directories (take less than a lock) |
| which contain filenames that begin with a space or some other |
| punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad |
| Bug: #525114) |
| |
| |
| Programmer's Notes |
| ------------------ |
| |
| Add new test, f_rehash_dir, which checks to make sure e2fsck -D works |
| correctly. |
| |
| The libcom_err function now has support for Heimdal's com_right_r |
| function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian |
| Bug: #558910) |
| |
| |
| E2fsprogs 1.41.10 (February 7, 2010) |
| ==================================== |
| |
| Fix resize2fs bug which causes it to access invalid memory. |
| |
| Add libss support for libreadline.so.6. |
| |
| Fix e2fsck's check for extent-mapped directory with an incorrect file |
| type. |
| |
| Add new e2fsck.conf configuration option, default/broken_system_clock |
| to support systems with broken CMOS hardware clocks. Also, since too |
| many distributions seem to have broken virtualization scripts now, |
| e2fsck will by default accept dates which are off by up to 24 hours by |
| default. (Addresses Debian Bugs: #559776, #557636) |
| |
| Fix a bug where mke2fs may not use the best placement of the inode |
| table when there is only room for a single block group in the last |
| flex_bg. |
| |
| E2fsck is now smarter when it needs to allocate blocks in the course |
| of fixing file system problems. This reduces the number of spurious |
| differences found in pass #5. |
| |
| E2fsck will no longer rehash directories which fit in a single |
| directory block. |
| |
| E2fsck now correctly handles holes in extent-mapped directories (i.e., |
| sparse directories which use extents). |
| |
| Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2(). |
| |
| Fix a bug in filefrag where on platforms which can allow file systems |
| with 8k blocks, that it doesn't core dump when it sees a file system |
| with 8k block sizes. (Thanks to Mikulas Patocka for pointing this |
| out.) |
| |
| E2fsck will correctly fix directories that are have an inaccurate |
| i_size as well as other problems in a single pass, instead of |
| requiring two e2fsck runs before the file system is fully fixed. |
| |
| Fix e2fsck so it will correctly find and detect duplicate directory |
| entries for non-indexed directories. ( Addresses Sourceforge Bug: |
| #2862551) |
| |
| Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or |
| thinly-provisioned storage device. This can be disabled using the -K |
| option. |
| |
| Enhance libext2fs so it works around bug in Linux version 2.6.19 |
| and earlier where the /proc/swaps file was missing the header on |
| the first line. |
| |
| Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file |
| was missing the header on the first line. |
| |
| Fix some big-endian bugs in e2fsck and libext2fs. |
| |
| Fix resize2fs so it works correctly on file systems with external |
| journals instead of failing early with the error "Illegal inode |
| number". |
| |
| Fix libss so that it does not seg fault when using a readline library |
| which does not supply a readline_shutdown() function. |
| |
| Updated dumpe2fs's usage message so it correctly gives the right |
| arguments summary for "-o superblock=<num>" and "-o blocksize=<num>". |
| (Addresses Launchpad Bug: #448099) |
| |
| Teach libext2fs to ignore the high 32 bits of the i_blocks field |
| when huge_file file system feature is set, but the inode does not |
| have the HUGE_FILE_FL flag set. |
| |
| Fix e2fsck's handling of 64-bit i_blocks fields. |
| |
| E2fsck will now print "Illegal indirect block", "Illegal |
| double-indirect block", etc., instead of "Illegal block #-1" or |
| "Illegal block #-2", etc. This makes it easier for users to |
| understand what has gone wrong. (Addresses SourceForge Bug: #2871782) |
| |
| Mke2fs now will obtain get device topology information from blkid and |
| use it to populate the superblock stride and stripe sizes. It will |
| also warn if the block device is misaligned |
| |
| Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug: |
| ##524526) |
| |
| Fix the libext2fs library code to round up the bitmap size to a 4-byte |
| boundary, to prevent spurious seg faults caused by the x86 |
| architecture. This doesn't affect Linux systems, but was a major |
| problem on a number of *BSD systems. (Addresses Sourceforge Bug: |
| #2328708) |
| |
| Fix resize2fs's minimum size required for a file system so it doesn't |
| fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131) |
| |
| Dumpe2fs now prints summary information about the contents of the |
| journal. |
| |
| Avoid printing scary error messages when e2fsck starts running |
| problems on low-memory systems, as it tends to panic and mislead the |
| user. (Addresses Debian Bug: #509529) |
| |
| Fix blkid's modules.dep parser so it handles compressed (.ko.gz) |
| modules files. (Address Red Hat Bug: #518572) |
| |
| Fix tune2fs so it can add a journal when an extent-enabled file system |
| is mounted. (Addresses Launchpad bug: #416648) |
| |
| Update Czech, Indonesian, Polish and Vietnamese translations (from the |
| Translation Project). |
| |
| Update/clarify man pages. (Addresses Sourceforge Bug: #2822186) |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs: #540111) |
| |
| Programmer's Notes |
| ------------------ |
| |
| The configure script supports the --with-cc, --with-ccopts, and |
| --with-ldopts options. Instead, the more standard use of CC=, |
| CCFLAGS=, and LDFLAGS= in the configure command line is used instead. |
| Also, --with-ld, which never worked, was also removed. |
| (Addresses Sourceforge Bug: #2843248) |
| |
| The in-tree header files are only used if the in-tree uuid or blkid |
| libraries are used. Otherwise, use the system-provided uuid or blkid |
| header files if using the system-provided libraries. |
| |
| Fix some build failures caused by --disable-* configure options. |
| |
| Work around a bug in autoconf 2.64. |
| |
| |
| E2fsprogs 1.41.9 (August 22, 2009) |
| ================================== |
| |
| Fix a bug in e2fsck routines for reallocating an inode table which |
| could cause it to loop forever on an ext4 filesystem with the FLEX_BG |
| filesystem feature with a relatively rare (and specific) filesystem |
| corruption. This fix causes e2fsck to try to find space for a new |
| portion of the inode table in the containing flex_bg, and if that |
| fails, the new portion of the inode table will be allocated in any |
| free space available in the filesystem. |
| |
| Make e2fsck less annoying by only asking for permission to relocate a |
| block group's inode table once, instead of for every overlapping |
| block. Similarly, only ask once to recompute the block group |
| checksums, instead of once for each corrupted block group's checksum. |
| |
| Fix filefrag to avoid print the extent header if the FIEMAP ioctl is |
| not present, and it needs to fall back to using the FIBMAP ioctl. |
| |
| Fix filefrag to correctly print the number of extents for zero-length |
| files. (Addresses Debian Bug: #540376) |
| |
| Filefrag now has a -B option which forces the use of the FIBMAP ioctl |
| to more easily debug the FIBMAP code. |
| |
| Fixed filefrag for non-extent based files. |
| |
| Add a new program, e2freefrag, which displays information about the |
| free space fragmentation in an ext2/3/4 filesystem. |
| |
| Fix inode resizing via tune2fs -I so that it works correctly in the |
| face of non-empty bad blocks inodes, and if the filesystem was |
| formatted using the "mke2fs -E stride=N" option for RAID arrays. |
| |
| Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail |
| and corrupt large directories if the directory needs to shrink by more |
| than one block. (Addresses Debian Bug: #537510) |
| |
| Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or |
| last mount times are in the future, they are corrected even if |
| buggy_init_scripts is set. This is needed because otherwise resize2fs |
| will refuse to resize the filesystem, even after running "e2fsck -f". |
| (Addresses Launchpad bug: #373409) |
| |
| E2fsck will now print much fuller information when the last mount time |
| or last written time is in the future, since most people can't seem to |
| believe their distribution has buggy init scripts, or they have a |
| failed CMOS/RTS clock battery. |
| |
| Enhance dumpe2fs to dump the extent information via the 'stat' |
| command, and more detailed extent information via the new command |
| 'dump_extents'. |
| |
| Update French, Polish, Czech, and Sweedish translation from the |
| Translation Project. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fixed miscellaneous gcc -Wall warnings. |
| |
| Fixed memory leak in error path in ext2fs_block_iterate2() |
| |
| Fixed non-Linux build of the intl directory by adding support for the |
| E/Q/V macros. |
| |
| The bitmap read/write functions now treat uninitialized bitmaps as |
| unallocated; this fixes a number of problems in all e2fsprogs for ext4 |
| filesystems when there is a need to allocate new blocks or inodes, and |
| there aren't any free blocks or inodes in the already-used block |
| groups. |
| |
| Improve ext2fs_extent_set_bmap() to avoid creating new extents which |
| get inserted into the extent tree when they are not needed. |
| |
| |
| E2fsprogs 1.41.8 (July 11, 2009) |
| ================================ |
| |
| Fix resize2fs's online resizing, fixing a regression which in |
| e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452) |
| |
| Fix potential filesystem corruptions caused by using resize2fs to |
| shrinking ext4 filesystems with extents enabled. (Addresses Red Hat |
| Bug: #510379) |
| |
| Optimize uuid_generate() to avoid running uuidd if it is not setuid or |
| setgid and the currently running program doesn't have write access to |
| the uuidd work directory. |
| |
| Add safety checks (for non-Linux systems) so that uuidd isn't run with |
| file descriptors 0, 1, and 2 closed; and if they are closed, uuidd |
| will be careful not to close the file descriptor for its unix domain |
| socket when it detaches itself from the controlling tty. Also add |
| safety checks so that if the unix domain socket between the uuid |
| library and uuidd program is closed for any reason, both the library |
| and the uuidd will return an appropriate error code instead of looping |
| in an infinite loop. |
| |
| The e2croncheck script, which creates an LVM snapshot and then checks |
| the ext3/4 filesystem via the LVM snapshot, has been added to the |
| contrib directory. |
| |
| Fix filefrag program for files that have more than 144 extents. |
| |
| Update French, Polish, Czech, Indonsian, and Sweedish translation from |
| the Translation Project. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bug #535530) |
| |
| Update/clarify man pages. |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fix compilation problem when configured with --disable-uuid. |
| |
| Don't build uuidgen if configured with --disable-uuid. |
| |
| Add the new library function ext2fs_test_inode_bitmap_range(), and |
| optimized ext2fs_test_block_bitmap_range(), which will be needed for |
| future optimizations for e2fsck. |
| |
| Fix makefile dependencies for libcom_err so that the Makefiles work |
| well on non-GNU make program. (Addresses Sourceforge Patches: #2813809) |
| |
| Enhance the build system so that the full set of commands executed by |
| the Makefiles are displayed, instead of the Linux kernel summary |
| output, if the build was configured with --enable-verbose-makecmds, or |
| if GNU make is in use and the V variable is non-null, i.e., via "make |
| V=1". |
| |
| |
| E2fsprogs 1.41.7 (June 29, 2009) |
| ================================ |
| |
| Fix a bug in libext2fs which can cause e2fsck and resize2fs to write |
| uninitalized data into the portion of the inode beyond the first 128 |
| bytes when operating on inodes mapped via extents; potentially |
| corrupting filesystems. |
| |
| Fix memory leaks in e2fsprogs, including a very large memory leak |
| which can cause e2fsck to run out of memory when checking very large |
| filesystems using extents. |
| |
| The logsave program will now filter out the ^A and ^B characters when |
| writing to the console. |
| |
| Harden ext2fs_validate_entry() so that lsdel will not read beyond the |
| end of the block even if the directory block is corrupted. |
| |
| Fix debugfs from core dumping if the logdump command fails to open the |
| output file. |
| |
| Enhance badblocks to print the currently tested block number when |
| interrupted with ^C. |
| |
| Fix lsattr to exit with a non-zero status when it encounters errors. |
| (Addresses RedHat Bugzilla #489841) |
| |
| Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger) |
| filesystems as the kernel when encoding rec_len >= 64k. For 64k |
| filesystems (currently all that is supported by e2fsprogs, this is |
| only a minor corner case). |
| |
| Resize2fs will now update the journal backup fileds in the sup0erblock |
| if the journal is moved; this avoids an unnecessary full fsck after |
| resizing the filesystem. (Addresses RedHat Bugzilla: #505339) |
| |
| Fix libext2fs to properly initialize i_extra_size when creating the |
| journal and resize inodes. |
| |
| Change badblocks to allow block sizes larger than 4k. |
| |
| Fix filefrag progam so it correctly checks for errors from the fiemap ioctl. |
| |
| Update Chinese and Czech translation from the Translation Project. |
| |
| Clean up various man pages. (Addresses Debian Bug #531385 and #523063) |
| |
| |
| Programmer's Notes |
| ------------------ |
| |
| Add --disable-libuuid option to configure which uses an in-system |
| installed version of libuuid; the private version is enabled by |
| default. |
| |
| Add --valgrind-leakcheck option to the test_script program which runs |
| valgrind with the appropriate options to find memory leaks. |
| |
| |
| E2fsprogs 1.41.6 (May 30, 2009) |
| =============================== |
| |
| Fix a critical regression in e2fsck introduced version 1.41.5 which |
| can undo updates to the block group descriptors after a journal replay. |
| |
| If e2fsck receives an I/O error while replaying the journal, prompt |
| the user whether they want to ignore the error or not; if e2fsck is |
| run in preen mode, force fsck to abort the preen pass. |
| |
| Fix a bug which would cause e2fsck to core dump if the filesystem |
| contains a corrupt extent header, and the user declines to clear the |
| inode. (Addresses Sourceforge Bug: #2791794) |
| |
| Fix e2fsck to restart only once in the case of multiple block groups |
| which inodes in use that are in the uninitialized part of the block |
| group's inode table. |
| |
| To reduce user confusion, if the /etc/mtab file is missing |
| ext2fs_check_mount_point and ext2fs_check_if_mounted will return a |
| new, explicit error code to indicate this case. This will cause |
| e2fsck to give a clearer error message when the user is using buggy |
| rescue CD's that don't properly set up /etc/mtab. (Addresses Debian |
| Bug: #527859) |
| |
| Fix e2fsck so that if the primary group descriptors are corrupted, but |
| the backup superblock is entirely invalid, to go back to using (and |
| fixing) the priary group descriptors instead of completely giving up |
| on the filesystem. (Addresses Debian Bug: #516820) |
| |
| Change e2fsck to not abort a preen pass if an inode is found to have |
| i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer |
| kernels (post 2.6.29) will ignore this field. So let's fix it |
| automatically during the preen pass instead of forcing the user to fix |
| this up manually. (Addresses Debian Bug: #526524) |
| |
| Add resource tracking for e2fsck passes 1b through 1d. |
| |
| Speed up e2fsck by eliminating unnecessary journal checks if the |
| filesystem is already mounted and doesn't need recovery (since the |
| kernel would have run the journal when the filesystem was mounted.) |
| Also speed up e2fsck by avoiding unnecessary block group descriptor |
| updates in ext2fs_close(). |
| |
| Add support to chattr to migrate inodes from using direct/indirect |
| blocks to extents. |
| |
| Avoid corrupting the filesystem if there is an attempt to shrink a |
| filesystem using resize2fs smaller than posible by making |
| ext2fs_set_bmap() more careful not to delete the old block until the |
| new block can be inserted. In addition, fix a bug in how the minimum |
| size of the filesystem (plus a safety margin) is calculated, and |
| modify resize2fs to refuse to shrink the filesystem below that minimum |
| size without the force flag. |
| |
| Teach blkid to try to figure out DM device names using take advantage |
| of information in sysfs when running on kernels (2.6.29 and later) |
| which provide this information in /sys/block/dm-<N>/dm/name; this is |
| much faster than scanning for the devncie number in /dev/mapper. |
| |
| Fix blkid to prefer /dev/mapper/<name> device names instad of the |
| private /dev/dm-X names. |
| |
| Add an -a option to debugfs's close_filesys command which writes any |
| changes to the superblock or block group descriptors to all of the |
| backup superblock locations. |
| |
| Add support to the filefrag program to use the FIEMAP ioctl. |
| |
| Update Chinese translation from the Translation Project. |
| |
| Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and |
| Launchpad Bug: #381854) |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bug #506064) |
| |
| |
| Programmer's Notes |
| ------------------ |
| |
| Add test code to make sure e2fsck's problem.c doesn't have two problem |
| codes assigned to duplicate values. |
| |
| Avoid using a hard-coded path for /bin/rm in block's test_probe.in. |
| (Addresses Sourceforge Bug: #2780205) |
| |
| Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty |
| function declaration for init_resource_track() and |
| print_resource_track() when RESOURCE_TRACK is not defined. |
| |
| The test code which is used to build the tst_csum progam has been |
| moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to |
| avoid compile problems caused by not having a prototype for |
| ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331) |
| |
| Update the config.guess and config.sub file to the latest from the |
| FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses |
| Debian Bug: #528330) |
| |
| Add a new function, ext2fs_extent_open2(), which behaves like |
| pext2fs_extent_open(), but uses the user-supplied inode structure |
| when opening an extent instead of reading the inode from disk. |
| |
| |
| E2fsprogs 1.41.5 (April 23, 2009) |
| ================================= |
| |
| Fix a number of filesystem corruption bugs in resize2fs when growing |
| or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem |
| is not mounted). |
| |
| Debugfs can now set i_file_acl_high via the set_inodes_field command, |
| and print a 64-bit file acl. This is useful for debugging filesystem |
| corruptions where the high bits of i_file_acl_high are set. E2fsck |
| will detect and fix non-zero i_file_acl_high on 32-bit filesystems |
| since some Linux kernel versions pay attention to this field even when |
| they shouldn't. |
| |
| Speed up e2fsck when checking clean filesystems by avoiding |
| unnecessary block reads, and coalescing the block group descriptor |
| blocks so they are read using a single read operation. |
| |
| The libuuid library will now close all file descriptors before running |
| uuidd. This avoids problems when the calling program has open sockets |
| which then never get closed because uuidd is a long-running helper |
| daeomn. (Addresses Launchpad bug: #305057) |
| |
| In order to avoid unnecessary full filesystem checks by e2fsck after |
| an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on |
| the backup superblocks. (Addresses Red Hat Bugzilla: #471925) |
| |
| Mke2fs will avoid trying to create the journal when run in |
| superblock-only mode (mke2fs -S), since the left-over journal in the |
| inode table will cause mke2fs to fail. |
| |
| Fix a bug in libext2fs functions that check to see if a particular |
| device or filesystem image is mounted, which would cause these |
| functions to report that a file identical to the (relative) pathname |
| used by a pseudo-filesystem was mounted when in fact it was not. |
| |
| Update Czech translation from the Translation Project. |
| |
| Add Chinese (simplified) translation from the Translation Project. |
| |
| Fix support for external journals (which was broken in e2fsprogs |
| 1.41.4). |
| |
| Fix a regression in debugfs where the "stat" command when no |
| filesystem was open would cause debugfs to crash with a segmentation |
| violation. |
| |
| Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be |
| used to support filesystems without a journal. Update the blkid |
| library so it understands this. |
| |
| The blkid library will remove an entry from the blkid cache |
| representing the entire disk if partitions are found, since presuambly |
| the device previously had no partition table, but has now transitioned |
| to using a partition table. |
| |
| Add a check to mke2fs and tune2fs that the argument to the -m option |
| (which specifies the reserved ratio) must be greater than zero. |
| (Addresses Debian Bug: #517015) |
| |
| Add support for tracking the number kilobytes written to the |
| filesystem via the superblock field s_kbytes_written. It will be |
| updated by the kernel as well as by e2fsprogs programs which write to |
| the filesystem. This is useful for tracking the wear to filesystems |
| on Solid Sstate Drives. |
| |
| Fix compatibility issue in the libext2fs info file and makeinfo |
| version 4.12. (Addresses Red Hat Bugzilla: #481620) |
| |
| Update/clarify man pages. (Addresses Debian Bug: #515693, #365619) |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bug: #506279) |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian |
| Bug: #521602) |
| |
| Fix various gcc compilation warnings and other programming cleanups. |
| (Addresses Red Hat Bugzilla: #486997) |
| |
| Add support for building the blkid command statically. |
| |
| Add support for disabling the built-in blkid library in favor of a |
| system-installed blkid implementation via the configure option |
| --disable-libblkid. |
| |
| |
| E2fsprogs 1.41.4 (January 27, 2009) |
| =================================== |
| |
| Fixed a bug which could sometimes cause blkid to return an exit value |
| of zero for a non-existent device (Addresses Debian Bug: #502541) |
| |
| Blkid will now recognize ext3 filesystems that have the test_fs flag |
| set as ext3 filesystems. |
| |
| The blkid library will now recognize btrfs filesystems and swap |
| devices currently used by user-level software suspend. |
| |
| Tune2fs now updates the block group checksums when changing the UUID |
| to avoid causing e2fsck to complain vociferously at the next reboot. |
| |
| Tune2fs's inode size resizing algorithms have been fixed so it is not |
| vastly inefficient for moderate-to-large filesystems, due to some |
| O(n**2) and O(n*m) algorithms that didn't scale well at all. |
| |
| Fix tune2fs's inode resizing algorithm so it will not corrupt |
| filesystems laid out for RAID filesystems; in addition, tune2fs will |
| refuse to change the inode size for filesystems that have the flex_bg |
| feature enabled. (This is a limitation in the current implementation |
| of tune2fs -I.) |
| |
| E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4 |
| filesystems with 32-bit block numbers, when the headers for 64-bit |
| block numbers was added. This regression has been fixed. |
| |
| Debugfs's ncheck command has been fixed to avoid printing garbage |
| characters at the end of file names. |
| |
| Fix resize2fs for ext4 filesystems. Some blocks that that need moving |
| when shrinking filesystems with uninit_bg feature would not be moved. |
| In addition, blocks and inode table blocks were not being correctly |
| freed when shrinking filesystems with the flex_bg feable, which caused |
| resize2fs -M to fail. Finally, when blocks are moved, make sure the |
| uninitialized flag in extents is preserved. |
| |
| Fix bug which caused dumpe2fs to abort with an error if run on a |
| filesystem that contained an external journal. |
| |
| Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check |
| for this in argv[0] to provide better legacy support for these |
| distributions. This is a practice that should NOT be continued, |
| however. |
| |
| Mke2fs now has a new option -U, which allows the user to specify the |
| UUID that should be used for the new filesystem. |
| |
| Mke2fs will treat devices that are exactly 16TB as if they were 16TB |
| minus one block. This allows users who have read that ext3 supports |
| up to 16TB filesystems and who create a 16TB LVM to not get confused, |
| since the true limit is really 16TB minus one block. |
| |
| E2fsck will no longer abort an fsck run if block group has an errant |
| INODE_UNINIT flag. |
| |
| E2fsck now distinguishes between fragmented directories and fragmented |
| files in verbose mode statistics and in the fragcheck report. |
| |
| Fix a bug in e2fsck which casued it double count non-contiguous |
| extent-based inodes. |
| |
| E2fsck will leave some slack space when repacking directories to allow |
| room for a few directory entries to be added without causing leaf |
| nodes to be split right away. |
| |
| Fix a bug which caused e2fsck to crash when it comes across a |
| corrupted interior node in an extent tree with the error message: |
| "Error1: Corrupt extent header on inode XXXXXX" |
| |
| E2fsck problem descriptions involving the journal are no longer |
| referred to as "ext3" problems, since ext4 filesystems also have |
| journals. |
| |
| Fix a long-standing bug in e2fsck which would cause it to crash when |
| replying journals for filesystems with block sizes greater than 8k. |
| |
| Update Catalan translation from the Translation Project. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs: #503057, #502323, #511207) |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fix build of e2fsck.profiled, and add support for building profiled |
| binaries in the misc directory if configured with --enable-profile. |
| |
| The ext2fs_open() function now performs more sanity checks on the |
| superblock to avoid potential divide by zero errors by other parts of |
| library. |
| |
| The ext2fs_read_inode_full() function now has a safety check to avoid |
| a segmentation fault on corrupted filesystems. |
| |
| The ext2fs_new_inode() function now has a sanity check so that if the |
| s_first_inode field in the superblock is insane, it will return |
| EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number. |
| |
| To avoid segmentation faults, ext2fs_block_alloc_stats() and |
| ext2fs_inode_alloc_stats() now validates the passed inode or block |
| number to avoid overrunning an array boundary. |
| |
| Various signed/unsigned errors for variables containing block numbers |
| have been fixed. |
| |
| Accomodations for gcc's stupidity in not realizing that constant |
| strings that do not contain a '%' character are safe to use in format |
| strings have been made so that distributions that want to compile |
| e2fsprogs with -Werror=format-security have an easier time doing so. |
| |
| Added a new 64-bit getsize interface, ext2fs_get_device_size2(). |
| |
| Added the utility make-sparse.c to the contrib directory. |
| |
| The ext2fs_block_iterate2() function now reflects errors from |
| ext2fs_extent_set_bmap() to the caller, if the callback tries to |
| change a block on an extent-based file, and ext2fs_extent_set_bmap() |
| fails for some reason (for example, there isn't enough disk space to |
| split a node and expand the extent tree. |
| |
| The ext2fs_block_iterate2() function will preserve the uninit flag in |
| extents when the callback function modifies a block in an extent-based |
| file. |
| |
| E2fsck will now flag filesystems that have an insane s_first_ino field |
| in their superblock, and attempt to use a backup superblock to repair |
| the filesystem. |
| |
| |
| E2fsprogs 1.41.3 (October 12, 2008) |
| =================================== |
| |
| E2fsck has been fixed so it prints the correct inode number for |
| uinit_bg related problems. |
| |
| E2fsck will now offer to clear the test_fs flag if the ext4 filesystem |
| is available on linux. This can be disabled via a configuration |
| option in /etc/e2fsck.conf. |
| |
| Fix a file descriptor leak in libblkid when checking to see if an ext4 |
| or ext4dev module exists. |
| |
| Fix a bug in e2fsck where in preen mode, if there are disk I/O errors |
| while trying to close a filesystem can lead to infinite loops. |
| (Addresses Red Hat Bugzilla #465679) |
| |
| Fix a bug in resize2fs where passing in a bogus new size of 0 blocks |
| will cause resize2fs to drop into an infinite loop. (Addresses Red |
| Hat Bugzilla: #465984) |
| |
| Add a check in the Unix I/O functions in libext2fs so that when a |
| device is opened read/write, return an error if the device is |
| read-only using the BLKROGET ioctl. |
| |
| Fix debugfs's ncheck command so that it prints all of the names of |
| hardlinks in the same directory. |
| |
| Fix a bug in libblkid so it correctly detects whether the ext4 and |
| ext4dev filesystems are available, so that the ext4dev->ext4 |
| fallback code works correctly. |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fix a parallel build problem by making sure util/subst is built before |
| trying to build the lib/et directory. (Addresses Sourceforge Bug: |
| #2143281) |
| |
| Updated "make depend" information for crc16.o |
| |
| |
| E2fsprogs 1.41.2 (October 2, 2008) |
| ================================== |
| |
| Fix e2fsck's automatic blocksize detection. This fixes a regression |
| from e2fsprogs 1.40.7 which caused e2fsck to fail if the user |
| specifies a block number using the -b option if the blocksize option |
| isn't also specified using -B. Unfortunately, users very commonly |
| invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup |
| superblock; in fack e2fsck will often suggest this kind of command |
| line. Oops. |
| |
| Enhance the debugfs's "ncheck" command so it will print all of the |
| pathnames for the specified inodes. (Previously, in some cases ncheck |
| might not print a pathname for an inode at all if some of the other |
| inodes had multiple hard links.) |
| |
| Enhance debugfs's "hash" command so the hash seed can be specified via |
| a command-line option. In addition, allow the hash algorithm to be |
| specified by name instead of just by number. |
| |
| Fix e2fsck so that we don't accidentally print the translation file's |
| header when asking the user a custom question so there is no prompt |
| defined for a particular problem record. For example, the question |
| "Run journal anyway" will get the PO header tacked on because e2fsck |
| erroneously passed the null string to _(). (Addresses Launchpad Bug: |
| #246892) |
| |
| Enhance badblocks so that it can test a normal file which is greater |
| than 2GB. |
| |
| Enhance the badblocks command so that it displays the time and |
| percentage complete when in verbose mode. (Addresses Debian Bug: |
| #429739) |
| |
| Fix a potential memory leak in a error handling path in debugfs's |
| ncheck function. |
| |
| Fix a potential memory corruption problem if a memory allocation fails |
| in resize2fs. |
| |
| Fix the usage message for debugfs's logdump command to be consistent |
| with its man manpage. |
| |
| Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech, |
| and Sweedish translation from the Translation Project. |
| |
| Add documentation for the file I/O functions to the libext2fs.texinfo |
| file. (Addresses Debian Bug: #484877) |
| |
| Update and clarified various man pages. (Addresses Launchpad Bug |
| #275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103) |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bug: #497619) |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fix a potential file descriptor leack in libcom_err by setting the |
| close-on-exec flag for a fd used for debugging. (Addresses Red Hat |
| Bugzilla #464689) |
| |
| Fix a potential race in libcom_err by using sem_post/sem_init. SuSE |
| has been carrying a patch for a long time to prevent a largely |
| theoretical race condition if a multi-threaded application adds and |
| removes error tables in multiple threads. Unfortunately SuSE's |
| approach breaks compatibility by forcing applications to link and |
| compile with the -pthread option; using pthread mutexes has |
| historically been problematic. We fix this by using sem_post/sem_init |
| instead. |
| |
| Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses |
| Sourceforge Bug: #2087502) |
| |
| Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded |
| libraries when using ELF shared libraries. |
| |
| Fix ELF shared library when building on systems that don't already |
| have the e2fsprogs shared libraries already installed. (Addresses |
| Sourceforge Bug: #2088537) |
| |
| Fix the pkg-config files so they work correctly when linking with |
| static libraries and fix the include directory so programs don't have |
| to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h> |
| instead. (Addresses Sourceforge Bug: #2089537) |
| |
| Make sure ext2fs_swab64() is compiled for all platforms, and not just |
| for x86. (Addresses Debian Bug: #497515) |
| |
| Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all |
| non-x86 platforms. (They had been removed for x86 earlier.) |
| |
| Fix diet libc compilation support, which had bitrotted due to lack of |
| TLC. Fixing this improves general portability. |
| |
| When installing the link library when using ELF shared libraries, |
| avoid using absolute pathnames if the link library and the shared |
| library are installed in the same directory. (Addresses Sourceforge |
| Bug: #1782913) |
| |
| Fix gen-tarball so it will work even if the top-level directory has |
| been renamed to something other than "e2fsprogs". Also make |
| gen-tarball print the size of the resulting tar.gz file. |
| |
| |
| E2fsprogs 1.41.1 (September 1, 2008) |
| ==================================== |
| |
| Many people are forgetting to update their mke2fs.conf file, and this |
| causes ext3, ext4, and ext4dev filesystems won't get created with the |
| proper features enabled. We address this in two ways. First, mke2fs |
| will issue a warning if there is not definition for an ext3, ext4, or |
| ext4dev filesystem and the user is trying to create such a filesystem |
| type. Secondly, when installing from a source build, "make install" |
| will provide basic configuration file handling for /etc/mke2fs.conf. |
| If it exists, and does not mention ext4dev, it will be moved aside to |
| /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will |
| be installed. If the existing /etc/mke2fs.conf file does mention |
| ext4dev, then "make install" will install official mke2fs.conf file as |
| /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that |
| they should look to see if any changes need to be merged. |
| |
| The mke2fs program will now create the journal in the middle of the |
| filesystem, since this minimizes seek times on average for fsync-heavy |
| workloads. In addition, mke2fs will now create journals using extents |
| for filesystems that support them. This results in a more efficient |
| encoding for the journal since it eliminates the need for using |
| indirect blocks. |
| |
| The mke2fs program will avoid allocating an extra block to the |
| journal. (Addresses Sourceforge Bug: #1483791) |
| |
| Mke2fs will correctly enforce the prohibition against features |
| (specifically read-only features) in revision 0 filesystems. (Thanks |
| to Benno Schulenberg for noticing this problem.) |
| |
| Mke2fs previously would occasionaly create some slightly non-optimally |
| placed inode tables; this bug has been fixed. |
| |
| The mke2fs and tune2fs programs now print the correct usage message |
| describing the maximum journal size. (Addresses Debian Bug: #491620) |
| |
| Add support for setting the default hash algorithm used in b-tree |
| directories in tune2fs (from a command-line option) or mke2fs (via |
| mke2fs.conf). In addition, change the default hash algorithm to |
| half_md4, since it is faster and better. |
| |
| The blkid library will now recognize MacOS hfsx filesystems, and |
| correctly extract the label and uuid for hfs, hfsx, and hfsplus |
| filesystems. (Addresses Sourceforge Feature Requests: #2060292) |
| |
| The blkid library has improved detection of JFS and HPFS filesystems. |
| (Addresses Launchpad Bug: #255255) |
| |
| The blkid library is now much more efficiently handling devicemapper |
| devices, mainly by no longer using the devicemapper library. This can |
| speed up access for systems with a large number of device mapper |
| devices. |
| |
| Blkid had a number of cache validation bugs in libblkid that have been |
| fixed. (Addresses Debian Bug: #493216) |
| |
| Resize2fs will now properly close out the "updating inode references" |
| progress bar so there is a newline printed before printing the final |
| "resize is successful" message. |
| |
| Resize2fs will now correctly handle filesystems with extents and/o |
| uninitialized block groups correctly when file/directory blocks need |
| to relocated (i.e., when shrinking a filesystem or if the resize_inode |
| is not present). To support this, the ext2fs library now supports |
| initializing inode and block bitmaps that are not yet initialized when |
| allocating them using ext2fs_new_block() and ext2fs_new_inode(). In |
| addition, e2fs_block_iterate2() can now support changing the location |
| of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has |
| been optimized to avoid creating unnecessary new extents when updating |
| the location of blocks in the extent tree. This will also help out |
| e2fsck's recovery of obscurely corrupted filesystems with extents, |
| when blocks are claimed by multiple inodes. |
| |
| Add support for on-line resizing ext4 filesystem with the flex_bg |
| filesystem feature. The method for doing so is not optimal, but to do |
| a better job will require kernel support. |
| |
| E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and |
| debugfs programs to not be able to read e2image files; the signed |
| vs. unsigned bug in the code which read bitmaps from the e2image has |
| been fixed. (Addresses Debian Bug: #495830) |
| |
| Resize2fs is now correctly managing the directory in-use counts when |
| shrinking filesystems and directory inodes needed to be moved from one |
| block group to another. This bug has been around since e2fsprogs |
| 1.26, and is largely harmless, but does cause a filesystem corruption |
| which will be flagged by e2fsck after the filesystem has been shrunk. |
| |
| E2fsck will no longer issue spurious complaints about the inode size |
| caused by very large extent-based files, and by blocks reallocated |
| using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses |
| Kernel Bugzilla: #11341) |
| |
| Mke2fs will now set the creation timestamp on the lost+found directory |
| and the root directory. (More generally, all new inodes created using |
| the ext2fs library will correctly set the creation timestamp.) |
| |
| E2fsck now correctly calculates ind/dind/tind statistics in the |
| presence of extent-based files. In addition, "e2fsck -v" will report |
| statistics of the depth of extent trees in the filesystem. E2fsck can |
| also give an inode fragmentation report using "e2fsck -E fragcheck" |
| which can be useful when debugging the kernel block allocation |
| routines. |
| |
| Fix support for empty directory blocks in ext4 filesystems with 64k |
| blocksize filesystems. |
| |
| E2fsck will now print the depth of corrupt htree directories. |
| |
| Debugfs's htree command now correctly understands extent-based |
| directories. It will also print out the minor hash as well as the |
| major hash. |
| |
| Debugfs has a new command which will print the supported features of |
| e2fsprogs, to enable scripts to know whether the installed version of |
| e2fsprogs can support a specific feature. |
| |
| Debugfs will now write files using extents for filesystems that |
| support them. |
| |
| The error message printed by "tune2fs -I" if the inode size was too |
| small was rather confusing, so it has been improved. Also, we won't |
| try to create an undo log until we know that command-line-specified |
| parameters such as "tune2fs -I <inode size>" are valid. |
| |
| Given some filesystems found "in the wild" that had non-zero block |
| group checksums even though the uninit_bg/gdt_sum feature was not |
| enabled, e2fsck would issue spurious error messages. Teach |
| ext2fs_group_desc_csum_verify() to ignore the block group checksum |
| entirely if the feature flag is not set. (Addresses Debian Bug: |
| #490637) |
| |
| The blkid program will now print out a user-friendly listing of all of |
| the block devices in the system and what they contain when given the |
| -L option. (Addresses Debian Bug: #490527) |
| |
| The filefrag program now has a more accurate calculation for the |
| number of ideal extents. (Addresses Debian Bug: #458306) |
| |
| The test I/O manager is now enabled by default, but its overhead is |
| only incurred when it would be enabled via the TEST_IO_FLAGS or |
| TEST_IO_BLOCK environment variables. |
| |
| Typographical errors in various program strings and usage messages |
| have been fixed; most of these were pointed out by the e2fsprogs |
| message catalog translators. (Thanks, translators!) |
| |
| Update and clarified various man pages, as well as some typographical |
| errors in the libext2fs texinfo file. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. |
| |
| Add Indonesian and update French, Polish, Dutch, German, Sweedish, |
| Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697, |
| #401092) |
| |
| Programmer's Notes |
| ------------------ |
| |
| Fix portability problem with the badblocks group; for systems that |
| don't have nanosleep(), try using usleep() instead. |
| |
| The "make check" target in the e2fsck directory now sets |
| LD_LIBRARY_PATH before running the various e2fsck internal library |
| regression tests. |
| |
| The crc32 regression test in the e2fsck library is now portable to |
| greater varienty of environments, including big-endian systems and |
| when cross-building e2fsprogs for embedded systems. (Addresses |
| Sourceforge Bug: #2019287) |
| |
| The ext2fs_extent_set_bmap() had some bugs when setting the first |
| block in a file, or when replacing a single block extent. Those cases |
| fortunately were came up relatively rarely when e2fsck was checking |
| files, but caused some problems when resize2fs was shrinking |
| extent-based files. |
| |
| Fix a potential core-dumping bug in libe2p's iterate_on_dir() |
| function. |
| |
| Various ext2fs library functions --- ext2fs_block_iterate2(), |
| ext2fs_initialize() and ext2fs_extent_open() --- now correctly free |
| allocated memory to avoid memory leaks in all of their error return |
| paths. |
| |
| Ext2ed was failing to build because masix support had been removed in |
| the rest of e2fsprogs, so ext2ed no longer has masix support, either. |
| |
| The configure script now respects the LDFLAGS environment variable if |
| it is set when configure is called. (Addresses Sourceforge Feature |
| Request: #1937287) |
| |
| Libuuid is now more portable to the Windows platform. (Addresses |
| Sourceforge Feature Request: #1937287) |
| |
| The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of |
| bare echo commands so that configure flags such as --quiet work |
| correctly. (Addresses Sourceforge Patches: #2058794) |
| |
| A few uses of sprintf have been removed from the ext2fs library to |
| make life easier for bootloaders with a limited libc environment. |
| (Addresses Sourceforge Bug: #2049120) |
| |
| The ext2fs_read_inode() checks the validity of the inode number passed |
| to it earlier, to avoid doing some needless work when it would fail |
| anyway. |
| |
| The ext2fs_open() checks the validity of the blocksize parameter |
| passed to it earlier, to avoid doing some needless work when it would |
| fail anyway. |
| |
| Disable a very annoying automatic "%.sh -> %" GNU make rule in the |
| top-level Makefile. That automatic rule is used to better support |
| SCCS, but it caused problems for a particular niche distribution which |
| likes to use configure.sh files to store the configure options used to |
| build a package. Unfortuntaely GNU make will use the configure.sh to |
| replace the configure script, resulting in a self-inflicted fork bomb |
| leading to an out-of-memory crash. |
| |
| To support old GNU C compilers don't use C99/C++ comments, but only |
| K&R style comments, and don't try to use __builtin_expect if __GNUC__ |
| is less than 3. (__builtin_expect is only supported for gcc versions |
| 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since |
| this is an optimization, we only try to use __builtin_expect for gcc 3 |
| and up.) |
| |
| In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of |
| __LITTLE_ENDIAN, which are only defined by glibc's header files and |
| hence isn't portable. |
| |
| For the convenience for some distributions that need a static tune2fs, |
| the Makefile for misc/ now has a tune2fs.static target. |
| |
| The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND |
| for extent-based files |
| |
| The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based |
| files. |
| |
| All source files no longer have any trailing white space. |
| |
| The io_channel_read_blk64() and io_channel_write_blk64() functions are |
| now functions instead of C preprocessor macros to provide better |
| forward compatibility. |
| |
| The e2fpsrogs translation template now expands the @x abbrevation. |
| |
| Various namespace leackages in libblkid, libe2p, and libext2fs have |
| been fixed. |
| |
| Fix a parallel build problem in e2fsprogs. |
| |
| E2fsprogs is now more portable to Solaris. |
| * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's |
| are always present. |
| * Scripts do not assume that /bin/true is always in /bin |
| * Don't use __FUNCTION__ since Solaris's C99 doesn't support it. |
| * Flush stdio handles before calling setbuf(), since Solaris will |
| discard any pending output to the stream. |
| * Define _XOPEN_SOURCE to 600 since Solaris's header files are very |
| picky about which C compiler can beused for SUSv3 conformance. |
| Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500), |
| and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600). |
| Since we need some SUSv3 functions, consistently use SUSv3 so |
| that e2fsprogs will build on Solaris using c99. |
| * Solaris C99 does not support varargs C preprocessor macros |
| * Solaris header files pollute the C namespace if in/netinet.h |
| is included, which conflicts with e2fsprogs' use of the kmem_cache_t |
| typedef. |
| * Solaris ships with a pathetically ancient shell in /bin/sh so we |
| avoid the use of various more avanced shell constructs such as $(). |
| |
| The "make rpm" command will now take some extra configure optiosn from |
| the build environment without needing to patch the source tree. |
| |
| The ext2fs_add_dir_block() function will now grow the dblist more |
| aggressively as an optimization to avoid copying the array too often. |
| |
| The e2fsck_write_bitmaps() will write the block and inode bitmaps |
| together instead of in two passes. |
| |
| |
| E2fsprogs 1.41 (July 10, 2008) |
| ============================== |
| |
| Add support for ext4 filesystem features, in particular extents, |
| uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add |
| support for checking journal checksums. Debugfs will print new |
| superblock and inode fields that were defined for ext4. For example, |
| the nanosecond and i_version fields of an inode, and the |
| s_min_extra_isize and s_wanted_extra_isize fields from the superblock. |
| Note: Resize2fs doesn't currently support the combination of flex_bg |
| and !resize_inode. (Addresses Debian Bug: #388452, #425477) |
| |
| Tune2fs can support migrating a filesystem from using 128 byte inodes |
| to 256 byte inodes, so it can take advantage of the full features of |
| ext4. |
| |
| Add support for "undo" support. E2fsck and mke2fs can optionally |
| record an undo log which can replayed by the program e2undo. |
| |
| E2fsck could damage a filesystem by trying to relocate inode tables |
| due to corrupted block group descriptors, where the attempted inode |
| table relocation would do far more harm than good. E2fsck has been |
| fixed to detect this these sorts of corrupted block group descriptors |
| much earlier in e2fsck processing, so it can try to use the backup |
| superblock and block group descriptors first. This should be a much |
| better strategy for recovering these types of corrupted filesystems. |
| (Addresses Sourceforge Bug: #1840291) |
| |
| E2fsck will display a more understandable message when the last check |
| field in the superblock is in the future. (Addresses Debian Bug: |
| #446005). |
| |
| E2fsck now performs more extensive and careful checks of extended |
| attributes stored in the inode. |
| |
| Enhance mke2fs to print a more explanatory error message when |
| ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug: |
| #488663) |
| |
| Fix mke2fs to use a default block size of 4k when formatting an |
| external journal device. This is done by using a fixed filesystem |
| type list that consists only of the single filesystem type "journal" |
| when looking up configuration keys in /etc/mke2fs.conf. (Addresses |
| Debian Bug: #488663) |
| |
| Speed up how mke2fs writes the journal data blocks by writing the disk |
| blocks in larger chunks. |
| |
| Fix blkid handling of stale devices. Fix a bug which could cause a |
| core dump while garbage collecting the blkid cache, and assure that |
| blkid_find_dev_with_tag() never returns a non-existent device. Also, |
| if a filesystem is found at a new /dev location, eliminate any |
| duplicate stale entries which can not be verified. |
| (Addresses Debian Bugs: #487758, #487783) |
| |
| Add more paranoid checks for LVM volumes and swap partitions in |
| blkid's probe function, to reduce the chances of false positives. |
| |
| The mke2fs program now has a much more sophisticated system for |
| controlling configuration parameters of a newly created filesystem |
| based on a split filesystem and usage type system. The -t option to |
| mke2fs was a deprecated alias to -c; it now specifies a filesystem |
| type (ext2, ext3, ext4, etc.), while the -T option can now be a comma |
| separated usage list. The filesystem type information and type |
| information is used to extract configuration parameters from the |
| /etc/mke2fs.conf file. |
| |
| The mke2fs program will no longer complain and request the -f option |
| when the user tries to create a filesystem with greater than 2**31 |
| blocks. |
| |
| When creating a filesystem for the GNU Hurd use a fs-type of Hurd and |
| adjust the mke2fs.conf file so filesystems for the Hurd are created |
| with a blocksize of 4096 and inode size of 128, which is all it knows |
| how to handle. (Addresses Debian Bug: #471977) |
| |
| Mke2fs will always make sure that lost+found always has at least 2 |
| blocks, even for filesystems with very large blocksizes (i.e., 64kb). |
| |
| Resize2fs will now print the minimum needed filesystem size if given |
| the -P option, and will resize the filesystem to the smallest possible |
| size if given the -M option. |
| |
| Fix resize2fs to clean up the resize_inode if all of the reserved gdt |
| blocks are consumed during an off-line resize. |
| |
| The "ls" command in debugfs now supports the -p option, which causes |
| it to quote the filenames so that spaces or tabs in directory entries |
| are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses |
| Sourceforge Feature Request: #1201667) |
| |
| Fix a potential off-by-one buffer oveflow in the fs_device_name in an |
| e2image file. |
| |
| The chattr program will return a non-zero exit code in case of |
| failures, and error messages can be suppressed with the -f option. |
| (Addresses Red Hat Bugzilla: #180596) |
| |
| Fix a bug in badblocks which caused it to overrun an array and likely |
| crash if more than 8 test patterns are specified using the -t option. |
| (Addresses Debian Bug: #487298) |
| |
| Add support to badblocks to limit how quickly it reads from the disk |
| drive (so it can be used for background scrubbing), and so it will |
| abort after finding a given number of errors. |
| |
| Remove support for the legacy big-endian filesystem format which only |
| existed on extremely long-dead PowerPC kernels almost a decade ago. |
| |
| Remove MASIX support from e2fsprogs. |
| |
| Add I/O statistics reporting to e2fsck. |
| |
| Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch, |
| Czech translations. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs: #487443, #487675, #490003) |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages. |
| (Addresses Debian Bugs: #393313, #487849, #440983, #440981) |
| |
| Programmer's Notes |
| ------------------ |
| |
| Factor out bitmap code in preparation for adding 64-bit new-style |
| bitmaps. |
| |
| Fix gcc -Wall warnings |
| |
| Fix the pkg-config files so that private librares are specified in |
| "Libs.private:". |
| |
| Fix the libext2fs.texinfo manual so it builds with modern versions of |
| texinfo. |
| |
| Silence the makefile from showing the awk command used to build the |
| |
| Clean up the badblocks group so to make it more portable and robust. |
| |
| Avoid using predictable filenames in /tmp in blkid's regression test |
| suite. Also remove bashism's in the regression test script. |
| |
| If the configure script is given --with-diet-libc, don't use thread |
| local storage, since diet libc doesn't support TLS. (Addresses |
| Sourceforge Bug: #2000654) |
| |
| Fix the blkid regression test suite to tolerate older versions of |
| mkswap that don't support the -U option. |
| |
| A few library routines have been converted to support 64-bit block |
| numbers; in particular, the I/O manager functions, the test_io, |
| inode_io, and unix_io managers have all be converted to support 64-bit |
| operation. |
| |
| Debugfs can now be extended for use by test programs. See |
| lib/ext2fs/extents.c for an example for how it can be used. The test |
| program links against the debugfs object files, and provides |
| additional commands by defining an auxiliary libss command table. |
| |
| The lazy_bg filesystem feature, which was only used by developer's |
| testing, has been removed since it has been largely supplanted by |
| uninit_bg. This also simplifies the code. |
| |
| |
| E2fsprogs 1.40.11 (June 17, 2008) |
| ================================= |
| |
| Mke2fs, tune2fs, and resize2fs now use floating point to calculate the |
| percentage of reserved blocks. (Addresses Debian Bug: #452639) |
| |
| Updated Spanish and Catalan translations. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs: #483962, #483023) |
| |
| Add detection for ZFS volumes to the libblkid library. |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages. |
| (Addresses Debian Bug: #486463) |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fix marginal C code in probe_lvm2() function to the blkid library more |
| portable for older compilers. |
| |
| Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473) |
| |
| Fix ext2fs_swap{16,32,64} functions so they can be used by external |
| applications on big-endian machines. (Addresses Debian Bug: #484879) |
| |
| |
| E2fsprogs 1.40.10 (May 21, 2008) |
| ================================ |
| |
| When deciding whether or not to revalidate a blkid cache entry, if the |
| device's mtime is newer than the last time the cached entry was |
| validated, force a revalidation. |
| |
| Fix a potential data corruption bug in e2fsck in the journal replay. |
| The chances of this is happening is extremely remote, especially the |
| default data=ordered or data=writeback modes. However, if a block |
| which has been journalled starts with the first four bytes 0xc03b3998, |
| when e2fsck replays the journal, those four bytes will be replaced |
| with zero's. Fortunately, it is highly, highly unlikely for e2fsck |
| metadata to begin with those fatal 4 byte sequence, and unless |
| data=ordered mode is in use, data blocks are never journaled. |
| |
| Updated German, Dutch, Sweedish, and Vietnamese translations. |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. |
| |
| Remove default sizes of types when cross compiling, since autoconf |
| 2.50 can figure this out automatically now. |
| |
| |
| E2fsprogs 1.40.9 (April 27, 2008) |
| ================================= |
| |
| SuSE's security team audited uuidd and came up with a few minor |
| issues. None of them are serious given that uuidd runs setuid as a |
| unprivileged user which has no special access other than libuuid |
| directory, but it's good to get them fixed. |
| |
| One additional fix in ext2fs_swap_inode_full() needed for resize2fs to |
| work correctly with in-inode extended attributes. |
| |
| Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese |
| translations. |
| |
| Debugfs will avoid using a pager if the standard output is not a tty. |
| |
| Fix debugfs and tune2fs to correctly handle daylight savings time when |
| parsing a time string. |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages. |
| |
| Fix fsck completion bars when multiple filesystems were being checked |
| in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug: |
| #203323, Addresses Sourceforge Bug: #1926023) |
| |
| Fix fsck so that progress information is sent back correctly when |
| multiple filesystems are being check and the output of fsck is being |
| redirected to a file descriptor. Also, include the device name (w/o |
| spaces) in the progress information sent back via a file descriptor. |
| (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug: |
| #1926023) |
| |
| Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems. |
| |
| If logsave receives a SIGTERM or SIGINT signal, it will now pass that |
| signal to its child process. |
| |
| Fix mke2fs's creation of are resize inode when there is a non-standard |
| s_first_data_block setting. |
| |
| Fix bug in blkid when run by an unprivileged user; most devices were |
| not reported correctly. 9Addresses Launchpad Bug: #220275) |
| |
| Mke2fs will not allow the logically incorect combination of |
| resize_inode and meta_bg, which had previously caused mke2fs to create |
| a corrupt fileystem. |
| |
| Fix fsck in German locales so that a 'j' means yes. |
| (Addresses Sourceforge Bug: #1947683) |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. |
| |
| Update valgrind options in test_script to work with valgrind 3.2.3 |
| |
| Update texinfo.tex to a much newer version from the FSF. |
| |
| Remove bashism for configure script and from the lib/ss Makefile. |
| Addresses Sourceforge Bug: 1921969 |
| |
| Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt. |
| |
| Fix build system so that if texinfo is not installed, it won't print a |
| (harmless) error message. |
| |
| |
| E2fsprogs 1.40.8 (March 13, 2008) |
| ================================= |
| |
| Fixed e2image -I so it works on image files which are larger than 2GB. |
| |
| Fixed e2fsck's handling of directory inodes with a corrupt size field. If |
| the size is larger than the number of blocks found in the inode, don't |
| try to allocate extra empty blocks at the end of the directory to make |
| up the difference; there's no point to doing that. In addition, if |
| the size is not a multiple of a blocksize, always fix it. |
| |
| E2fsck handled a pass 2 "should never happen error" by not giving |
| enough information and then core dumping. Unfortunately, it was all |
| too easy to trigger the "should never happen" situation if a |
| directory's inode size was not correct. This has been fixed, but |
| e2fsck has also been taught how to handle this situation more |
| gracefully, by simply removing the inode hash tree information, so |
| that it can be rebuilt again after e2fsck's pass 3. (Addresses |
| Launchpad Bug: #129395) |
| |
| Resize2fs had a bug resizing large inodes with extended attributes |
| that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed |
| completely on big-endian systems such as PowerPC. The bug should be |
| completely fixed now. Yay for regression test suites. (Addresses Red |
| Hat Bugzilla: #434893) |
| |
| Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese |
| translations. Many thanks to Philipp Thomas from Novell for stepping |
| up to become the new German translation maintainer! (Addresses Debian |
| Bugs: #302512, #370247, #401092, #412882). |
| |
| When e2fsck is clearing a corrupt inode's HTREE directory information, |
| make it clear that it is just clearing the HTREE information, not the |
| entire inode. |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages. |
| |
| Programmer's notes |
| ------------------ |
| |
| Add new functions, ext2fs_dblist_get_last() and |
| ext2fs_dblist_drop_last(), which allows the caller to examine the last |
| directory block entry added to the list, and to drop if it necessary. |
| |
| Fixed a portability problem in libblkid with DJGPP. |
| |
| Fix an obvious typo in an "internal error" message in e2fsck. Thanks |
| to Philipp Thomas for pointing this out. |
| |
| If the info files are not built, change "make install" so it doesn't |
| fail with an error code. |
| |
| |
| E2fsprogs 1.40.7 (February 28, 2008) |
| ==================================== |
| |
| Remove support for clearing the SPARSE_SUPER feature from tune2fs, and |
| depreciate the -s option, since it can result in filesystems which |
| e2fsck can't fix easily. There are very good reasons for wanting to |
| disable sparse_super; users who wants to turn off sparse_super can use |
| debugfs. (Addresses Sourceforge Bug: #1840286) |
| |
| Add missing options to mke2fs's usage message. (Addresses Sourceforge |
| Bug: #1751393) |
| |
| Fix bug in resize2fs when large (greater than 128 byte) inodes are |
| moved when a filesystem is shrunk; it was only moving the first 128 |
| bytes, so extended attributes were not getting moved. (Addresses Red |
| Hat Bugzilla: #434893) |
| |
| E2fsck now prints an explicit message when the bad block inode is |
| updated, to avoid confusion about why the filesystem was modified. |
| (Addresses Sourceforge Bug: #756460) |
| |
| Allow mke2fs and tune2fs manipulate the large_file feature. |
| Previously we just let the kernel and e2fsck do this automatically, |
| but e2fsck will no longer automatically clear the large_file feature. |
| It still isn't really necessary to worry about this feature flag |
| explicitly, but some users seem to care. (Addresses Red Hat Bugzilla: |
| #258381) |
| |
| Suppress message about an old-style fstab if the fstab file is empty. |
| (Addresses Debian Bug: #468176) |
| |
| Fix (really minor) bug in debugfs's find_free_block so it avoids |
| reporting a free block more than once if there are too few free blocks |
| in the filesystem. (Addresses Sourceforge Bug: #1096315) |
| |
| Change e2fsck to no longer clear the LARGE_FILES feature flag |
| automatically, when there are no more > 2GB files in the filesystem. |
| It's been almost a decade since there have been kernels that don't |
| support this flag, and e2fsck clears it quietly without telling the |

| |
| Inhance e2fsck's reporting of unsupported filesystem feature flags. |
| (Addresses Sourceforge Feature Request: #1175808) |
| |
| Fix option syntax in dumpe2fs for explicit superblock and blocksize |
| parameters. What was currently documented in the man page has been |
| broken for some time, due to getopt() implementation changes. The |
| option sytax has been changed to one which is can be more portable |
| supported and which is consistent with the format for extended options |
| in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994) |
| |
| Add support to tune2fs to clear the resize_inode feature. This |
| requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816) |

| Programmer's notes: |
| ------------------- |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bug: #466929) |
| |
| Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a |
| partially filled-in filesystem object on an error, so that e2fsck can |
| print more intelligent error messages. |
| |
| Add a new function e2p_edit_feature2() which allows the caller to |
| specify which feature flags are OK to set or clear, and which returns |
| more specific information about feature flags which are not allowed to |
| be set/cleared. |
| |
| Set the C locale in the test_script driver since it uses [A-Za-z]. |
| (Addresses Sourceforge Bug: #1890526) |
| |
| Use fcntl locking instead of lockf in libuuid since Cygwin doesn't |
| support lockf(). |
| |
| Change configure.in to avoid using the 'dc' command unless it is |
| absolutely needed. (i.e., when using parsing a WIP-style version |
| number) (Addresses Sourceforge Bug: #1893024) |
| |
| Add portability checks to support compilation under DJGPP. |
| |
| Update to the latest samba tdb code before the LGPLv3 change, which |
| fixes a realloc() leak on failure. |
| |
| Fix memory leak in ext2fs_alloc_block(). |
| |
| Fix makefile dependency issues for various install targets. |
| (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456) |

| |
| |
| E2fsprogs 1.40.6 (February 9, 2008) |
| =================================== |
| |
| Add support for returning labels for UDF filesystems in the blkid |
| library. |
| |
| Fix bug in the blkid library where cached filesystems was not being |
| flushed when opening USB devices returned the error ENOMEDIUM. |
| (Addresses Debian Bug: #463787) |

| |
| Programmer's Notes: |
| ------------------- |
| |
| Update e2fsprogs translation template and Vietnamese and Czech translations |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs: #436058) |
| |
| Don't try to create $DESTDIR/etc/init.d as part of make install as we |
| don't install the init.d script (and it's not the recommended way to |
| start uuidd anyway). (Addresses Sourceforge Bug: #1885085) |
| |
| Use thread local storage to fix a theoretical race condition if two |
| threads try to format an unknown error code at the same time in the |
| com_err library. |
| |
| |
| E2fsprogs 1.40.5 (January 27, 2008) |
| =================================== |
| |
| Fix a potential overflow big in e2image if the device name is too |
| long. |
| |
| Mke2fs will now create new filesystems with 256 byte inodes and the |
| ext_attr feature flag by default. This allows for much better future |
| compatibity with ext4 and speeds up extended attributes even on ext3 |
| filesystems. |
| |
| Teach e2fsck to ignore certain "safe" filesystem features which are |
| set automatically by the kernel. Having the kernel set features |
| automagically behind the user's back is a bad idea, and we should try |
| to break the kernel of this habit, especially for the newer ext4 |
| feature flags. But for now, we will try to avoid needless full checks |
| which can annoy users who are doing fresh installs. |
| |
| Add support in tune2fs and mke2fs for making a filesystem as being "ok |
| to be used with test kernel code". This will be needed for using test |
| filesystems with the latest ext4 kernel code. |
| |
| Change e2fsck -fD so that it sorts non-htree directories by inode |
| numbers instead of by name, since that optimizes performances much |
| more significantly. (Addresses-Sourceforge-Feature-Request: #532439) |
| |
| If e2image fills the disk, fix it so it exits right away instead of |
| spewing large numbers of error messages. |
| (Addresses-Sourceforge-Feature-Request: #606508) |
| |
| If ftruncate64() is not available for resize2fs, let it use ftrucate() |
| instead, but have it check to see if the size would get truncated, and |
| skip calling ftruncate in that case. |
| |
| Add support for detecting HFS+ filesystems in the blkid library. |
| |
| Add supprt in the blkid library for ext4/ext4dev filesystems. |
| |
| Fix a bug in blkid where it could die on a floating point exception |
| when presented with a corrupt reiserfs image. |
| |
| Fix blkid's handling of ntfs UUID's so that leading zeros are printed |
| such that UUID string is a fixed length. |
| |
| Add sample python bindings for the uuid library to the contrib |
| directory. (Addresses-Sourceforge-Patches: #778817) |
| |
| Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it |
| will work with large files. (Addresses Sourceforge Feature Request: |
| #1257500 and Sourceforge Support Request: #1253511) |
| |
| Allow the debugfs 'undel' command to undelete an inode without linking |
| it to a specific destination directory, since this might require |
| allocating blocks that could overwrite some yet-to-be-recovered |
| deleted files. (Addresses-Sourceforge-Feature-Request: #967141) |
| |
| Update Swedish translations from the Translation Project. |
| |
| Programmer's Notes: |
| ------------------- |
| |
| Fix configure handling of --sbindir (which should rarely be used, but |
| someone did complain, so let's fix it). (Addresses Sourceforge Bug: |
| #498381) |
| |
| Updated e2fsprogs.spec file to include a new uuidd package |
| |
| Use pkg-config to determine where to find the devmapper library so we |
| can find out where it is located on different distributions. |
| |
| Fix Makefile race so that "make -j3 distclean" works correctly |
| |
| Fix portability problems on non-Linux/non-Hurd/non-Masix systems, |
| especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633, |
| #1819034, #1863819) |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs: #459403, #459475, #459614) |
| |
| Remove the --enable-dynamic-static configure option, and build e2fsck |
| dynamically by default. If the user wants e2fsck.static, he/she will |
| need to build it via "make -C e2fsck e2fsck.static" |
| |
| Fix various build warnings due to missing prototypes. |
| (Addresses Sourceforge Patch: #1861663, #1861659) |
| |
| |
| E2fsprogs 1.40.4 (December 31, 2007) |
| ==================================== |
| |
| Improve time-based UUID generation. A new daemon uuidd, is started |
| automatically by libuuid if necessary. This daemon is setuid to allow |
| updates to /var/lib/libuuid, so the clock sequence number can be |
| stored and so if the clock is set backwards, it can be detected. |
| (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla: |
| #233471) |
| |
| Filter out the NEEDS_RECOVERY feature flag when writing out the backup |
| superblocks. This avoids e2fsck from concluding that a full |
| filesystem check is required before backing up the superblock due to |
| changes in the feature flags. (Addresses Debian Bug: #454926) |
| |
| Fix fsck to only treat the '#' character as a comment at the beginning |
| of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem |
| will cause fsck to issue an bogus warning message. |
| (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147) |
| |
| Format control characters and characters with the high eighth bit set |
| when printing the contents of the blkid cache, to prevent filesystems |
| with garbage labels from sending escape sequences to the user's screen |
| that might, for example place it in graphics mode. (Addresses Ubuntu |
| Bug: #78087) |
| |
| Fix sign-extension problem on 64-bit systems in in the com_err |
| library. (Addresses Sourceforge Bug: #1809658) |
| |
| Avoid division by zero error when probing an invalid FAT filesystem in |
| the blkid library. (Addresses Sourceforge Bug: #1831627) |
| |
| Update Dutch, Polish, and Vietnamese translations from the Translation |
| Project. Remove the Rwandan translation upon advice of the |
| Translation Project. |
| |
| Programmer's Notes: |
| ------------------- |
| |
| Fix the libss "make check" regression test so that it works if the |
| current directory is not in the user's path or if the libss shared |
| library is not installed. (Addresses Sourceforge Bug: #1848974) |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages. |
| (Addresses Debian Bugs: #444883, #441872) |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs: #437720, #451172, #458017) |
| |

| (Addresses Sourceforge Bug: #1859778) |
| |
| Fix Hurd portability issues. (Addresses Debian Bug: #437720) |
| |
| |
| E2fsprogs 1.40.3 (December 5, 2007) |
| =================================== |
| |
| Fix a potential security vulnerability where an untrusted filesystem |
| can be corrupted in such a way that a program using libext2fs will |
| allocate a buffer which is far too small. This can lead to either a |
| crash or potentially a heap-based buffer overflow crash. No known |
| exploits exist, but main concern is where an untrusted user who |
| possesses privileged access in a guest Xen environment could corrupt a |
| filesystem which is then accessed by the pygrub program, running as |
| root in the dom0 host environment, thus allowing the untrusted user to |
| gain privileged access in the host OS. Thanks to the McAfee AVERT |
| Research group for reporting this issue. (Addresses CVE-2007-5497.) |
| |
| Fix hueristics in blkid which could cause a disk without partitions to |
| be incorrectly skipped when a loopback device is present. (Addresses |
| Red Hat Bugzilla #400321.) |
| |
| Fix e2image so that in raw mode it does not create an image file which |
| is one byte too large. |
| |
| Change mke2fs's usage message so it recommends the preferred -E option |
| instead of the deprecated -R option. |
| |
| Enhance the blkid library so it will recognize squashfs filesystems. |
| (Addresses Red Hat Bugzilla #305151.) |
| |
| Enhance e2fsck so it will force the backup superblocks to be backed up |
| if the filesystem is consistent and key constants have been changed |
| (i.e., by an on-line resize) or by e2fsck in the course of its |
| operations. |
| |
| Enhance blkid's detection of FAT filesystems; so that USB disks with |
| only a single bootable partition will not get missed. |
| |
| E2fsck will no longer mark a filesystem as invalid if it has time |
| errors (i.e., if superblock mount time or last write time is in the |
| future) and the user refuses to fix the problem. |
| |
| The Ubuntu init scripts don't properly set the system time correctly |
| from hardware clock if the hardware clock is configured to tick local |
| time instead of GMT time. Work around this as best as we can by |
| providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can |
| be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu |
| Bug #131201.) |
| |
| Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red |
| Hat Bugzilla #151533.) |
| |
| Fix e2fsck so that if the superblock is corrupt, but still looks |
| vaguely like an ext2/3/4 superblock, that it automatically tries to |
| fall back to the backup superblock, instead of failing with a hard |
| error. |
| |
| Make the e2fsprogs program more robust so that they will not crash |
| when opening a corrupt filesystem where s_inode_size is zero. |
| |
| Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric |
| arguments are detected as such and the parse error is reported to the |
| user. (Addresses Debian Bug #435381.) |
| |
| Change e2fsck so it will not complain if a file has blocks reallocated |
| up to the next multiple of a system's page size. |
| |
| Fix bug in ext2fs_check_desc() which will cause e2fsck to complain |
| about (valid) filesystems where the inode table extends to the last |
| block of the block group. (Addresses Red Hat Bugzilla #214765.) |
| |
| Fix a bug in ext2fs_initialize() which causes mke2fs to fail while |
| allocating inode tables for some relatively rare odd disk sizes. |
| (Addresses Red Hat Bugzilla #241767.) |
| |
| Add Catalan translation and update Dutch and Swedish translations |
| from the Translation Project. |
| |
| Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We |
| still had an issue when trying to figure out whether we need to |
| byte-swap fast symlinks that contained extended attributes. |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages. |
| (Addresses SourceForge Bug #1821333.) |
| |
| |
| Programmer's Notes: |
| ------------------- |
| |
| Fix mke2fs tests to avoid needing any significant ^M (CR) characters |
| |
| Add "make check" to the RPM spec file |
| |
| Fix "make install" and 'make unstall" in misc/Makefile.in so that it |
| works correctly when the prefix is not the root directory. |
| |
| Fix the resize2fs tests, r_move_itable and r_resize_inode, so they |
| clena up after themselves by deleting the test.img temporary file |
| after completing the test. |
| |
| Fixed a corner case bug ext2fs_unlink() when trying to delete the |
| first directory entry in a directory block and the last directory |
| entry in the previous directory block is not in use. Fortunately |
| ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in |
| places where it is extremely unlikely to run into this corner case. |
| |
| Fix missing dependency which would cuase parallel builds to fail. |
| (Addresses Sourceforge Bug #1842331.) |
| |
| Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c |
| calling open(O_CREATE) with a missing mode parameter. |
| |
| Fix the test_ss.c in lib/ss so it can be used as an example |
| application program for the library as well as a regression test |
| suite. |
| |
| Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes |
| are properly passed back up through the call stack. |
| |
| E2fsprogs 1.40.2 (July 12, 2007) |
| ================================ |
| |
| A recent change to e2fsck_add_dir_info() to use tdb files to check |
| filesystems with a very large number of filesystems had a typo which |
| caused us to resize the wrong data structure. This would cause a |
| array overrun leading to malloc pointer corruptions and segfaults. |
| Since we normally can very accurately predict how big the the dirinfo |
| array needs to be, this bug only got triggered on very badly corrupted |
| filesystems. |
| |
| Fix a bug in e2fsck which caused it to incorrectly salvange |
| directories when the last entry's rec_len is bogusly too big. This |
| resulted in a nonsense filesystem corruption to be reported, and |
| required a second run of e2fsck to fully fix up the directory. |
| |
| Update tune2fs man page to include more discussion of reserved blocks |
| (Addresses Launchpad bug #47817) |
| |
| Update Turkish, Polish, Dutch, and Vietnamese PO files from the |
| Translation Project |
| |
| |
| E2fsprogs 1.40.1 (July 7, 2007) |
| =============================== |
| |
| Fix bug which could cause libblkid to loop forever. When revalidating |
| a partition where there is obsolete information in /etc/blkid.tab, we |
| end up freeing a the type tag without clearing dev->bid_type, causing |
| blkid_verify() to loop forever. (Addresses Debian Bug: #432052) |
| |
| The Turkish translation has a bug in it where it has the translation |
| of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at |
| @E, recursively, forever, until the stack fills up and e2fsck core |
| dumps. We fix this by making e2fsck stop @-expansions after a |
| recursive depth of 10, which is far more than we need. |
| (Addresses Sourceforge Bug: #1646081) |
| |
| Compile the default mke2fs.conf into mke2fs program. People are |
| getting surprised by mke2fs creating filesystems with different |
| defaults than earlier versions of mke2fs if mke2fs.conf is not |
| present. So we now create a built in version of mke2fs.conf file |
| which is used by mke2fs if the /etc/mke2fs.conf is not present. |
| (Addresses SourceforgeBug: #1745818) |
| |
| Improve the config/parse_types.sh helper script. Fix a potential |
| security problem if e2fsprogs is built as root (as Gentoo does!). In |
| addition fix the script and how it is called from the configure script |
| so that it does the right thing when cross-compiling. (Fixes Gentoo |
| bug: #146903) |
| |
| Update Vietnamese, French, and Dutch PO files from the Translation |
| Project. Also created a new e2fsprogs.pot file for translator. |
| |
| Fix bogus strip permission errors when building under Debian. When |
| building the e2fsprogs dpkg's, the dh_strip command emits a large |
| number of error messages caused by the permissions not being right. |
| So run dh_fixperms before running dh_strip. |
| |
| Programmer's Notes: |
| ------------------- |
| |
| Add new function: profile_set_default(). This function sets the value |
| of the pseudo file "<default>". If the file "<default>" had |
| previously been passed to profile_init(), then def_string parameter |
| will be parsed and used as the profile information for the "<default>" |
| file. |
| |
| Fix mk_cmds's error reporting so that it is unambiguous that it is the |
| mk_cmds script which is generating the error. (Obviates Gentoo patch: |
| e2fsprogs-1.32-mk_cmds-cosmetic.patch) |
| |
| Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high |
| priority" environment variable that overrides all others, where as |
| LANG is the lowest priorty environment variable. If LC_ALL is set, it |
| doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and |
| the all the rest are set. This will assure that the locale when |
| running the test suites is the "C" locale. (Obviates Gentoo patch: |
| e2fsprogs-1.38-tests-locale.patch) |
| |
| |
| E2fsprogs 1.40 (June 29, 2007) |
| ============================== |
| |
| Fix divide by zero error in blkid's NTFS probing logic. |
| |
| Add new blkid -g option which causes the blkid cache to be garbage |
| collected. |
| |
| Fix a bug in libblkid which could cause the internal field bid_type to |
| become corrupted. Fortunately bid_type isn't used much, and bid_label |
| and bid_uuid is only used by debugging code, so the impact of this bug |
| was very minor. |
| |
| Mke2fs will now store the RAID stride value when a filesystem is |
| created with a requested RAID stride, and then use it automatically in |
| resize2fs. |
| |
| Mke2fs has a sanity check added to make sure (inode_size * num_inodes) |
| isn't too big. In some cases Lustre users have tried specifying an |
| inode size of 4096 bytes, while keeping an inode ratio of one inode |
| per 4096 bytes. |
| |
| Improve sanity check in e2fsck's algorithm for finding a backup |
| superblock, so that it won't accidentally find a superblock that was |
| located in the journal, and then later reject it as being not a valid |
| backup superblock. |
| |
| Fix e2fsck get_size logic so that it will work with the Linux floppy |
| driver. The Linux floppy driver is a bit different from the other |
| block device drivers, in that if the device has been opened with |
| O_EXCL, it disallows another open(), even if the second open() does |
| not have the O_EXCL flag. (Addresses Debian Bug: #410569) |
| |
| Fix error checking of badblock's last-block and start-block arguments. |
| (Addresses Debian Bug: #416477) |
| |
| Fix e2fsck so that it doesn't overwrite the backup superblocks when |
| recovering a journal until the master superblock has been confirmed as |
| being sane. |
| |
| Change the blkid library to be much more paranoid about concluding |
| that a partition contains an NTFS filesystem, and fetch the UUID and |
| LABEL information from NTFS filesystems. (Addresses Launchpad Bug: |
| #110138) |
| |
| Factor out the code which sets the default journal size and move it |
| into libext2fs. |
| |
| Enhance e2fsck so it will recreate the ext3 journal if the original |
| journal inode was cleared to due it being corrupt after finishing the |
| filesystem check. |
| |
| Fix e2fsck so that it updates the journal inode if it is corrupted and |
| the backup journal information from the superblock was successfully |
| used to recover the filesystem. |
| |
| Fix e2fsck so that it checks all of the blocks in the journal inode |
| for validity. The original code only checked the direct blocks to |
| make sure the journal inode was sane. Unfortunately, if some or all |
| of the indirect or doubly indirect blocks were corrupted, this would |
| not be caught. |
| |
| Add support in blkid to detect LUKS encrypted partitions. |
| |
| Add extra sanity checks for extended attributes in the case where the |
| size is zero but the offset is very large. |
| |
| Fix byte-swapping issues for large inodes in ext2fs_read_inode_full() |
| and ext2fs_get_next_inode_full(). |
| |
| Clarify the copyright licenses used by the various libraries in |
| the top-level COPYING file (Red Hat Bugzilla: 166058) |
| |
| Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane. |
| |
| Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's. |
| |
| Remove check in e2fsck which requires EA's in inodes to be sorted; |
| they don't need to be sorted, and e2fsck was previously wrongly |
| clearing unsorted EA's stored in the inode structure. |
| |
| Allow mke2fs or tune2fs to create a substantially larger journal (up |
| to 10,240,000 blocks). |
| |
| Fix MD superblock detection, and make sure the correct UUID is |
| reported from the MD superblock. |
| |
| Fix a signed vs. unsigned bug in debugfs. |
| |
| Enhance debugfs's date parser so that it accepts integer values. |
| |
| Fix e2fsck's pass1c accounting so it doesn't terminate too early if a |
| file with multiply claimed blocks is hard linked. or not at all if the |
| root directory contains shared blocks |
| |
| Enhance debugfs so it can modify the block group descriptors using the |
| command set_block_group_descriptor. |
| |
| Improve e2fsck's reporting of I/O errors so it's clearer what it was |
| trying to do when an error happens |
| |
| Fix a bug in in how e2fsprogs byte swaps inodes containing fast |
| symlinks that have extended attributes. (Addresses Red Hat Bugzilla: |
| #232663 and LTC Bugzilla: #27634) |
| |
| Fix potential file descriptor leak in ext2fs_get_device_size() in an |
| error case. |
| |
| Add libreadline.so.5 support to libss. |
| |
| Impove badblocks -n/-w exclusive usage message. |
| |
| Fix dump_unused segfault in debugfs when a filesystem is not open |
| |
| Fix memory leak in blkid library. (Addresses Debian Bug: #413661) |
| |
| Allow the debugfs lcd command to work w/o a filesystem being open. |
| (Addresses LTC Bugzilla #27513) |
| |
| Fix e2fsck to clear i_size for special devices with a bogus i_blocks |
| field on the first pass. |
| |
| Fix e2fsck to set the file type of the '..' entry when connecting |
| a directory to lost+found. (Addresses Lustre Bug: #11645) |
| |
| Enhance e2fsck to recover directories whose modes field were corrupted |
| to look like special files. This is probably only useful in |
| artificial test cases, but it will be useful if we ever do the "inodes |
| in directory" idea for ext4. |
| |
| Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug: |
| #412614) |
| |
| Fix resize2fs parsing of size parameter (in sector units). This was |
| actually a bug in libe2p's parse_num_blocks() function. When handling |
| the 's' suffix, it was ignoring the blocksize information passed in |
| from the caller and always interpreting the number in terms of a 1k |
| blocksize. (Addresses Debian Bug: #408298) |
| |
| There was a floating point precision error which could cause e2fsck to |
| loop forever on really big filesystems with a large inode count. |
| (Addresses Debian Bug: #411838) |
| |
| Fix memory leak in ext2fs_write_new_inode() |
| |
| Add support for using a scratch files directory to reduce e2fsck's |
| memory utilization on really big filesystems. This uses the TDB |
| library. See the [scratch_files] section of the e2fsck.conf man page |
| for more details. |
| |
| Fixed type-punning bug which caused dumpe2fs to crash on the Arm |
| platform (Addresses Debian Bug: #397044) |
| |
| Add explanatory message to badblocks that -n and -w are mutually exclusive |
| (Addresses Debian Bug: #371869) |
| |
| Allow debugfs and dumpe2fs to support fs features under development. |
| |
| Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to |
| ext2fs_open() , which allows application to open filesystes with features |
| which are currently only partially supported by e2fsprogs. |
| |
| Allow unix_io to support offsets greater than 2G (Addresses |
| SourceForge Bug: #1547922) |
| |
| Fixed overflow and signed/unsigned problems caused by the number of |
| blocks or inodes exceeding 2**31 or being close to 2**32-1. |
| |
| Add support for unsigned directory hash calculations with hints in the |
| superblock to fix cross-architectural portability for htree |
| directories with filenames where the high 8th bit is set. (Addresses |
| Debian: #389772) |
| |
| Fix resize2fs so that it gives user-intelligible error messages if the |
| filesystem or the kernel does not support on-line resizing. |
| (Addresses Debian Bug: #380548) |
| |
| Require mke2fs -F -F for really dangerous operations, since -F is |
| needed for less dangerous operations such as creating filesystems |
| images in regular files, or creating filesystems on whole block |
| devices. These relatively innocuous usages should NOT be confused |
| with running mke2fs on an apparently-mounted or in-use filesystem. |
| |
| Allow the default inode size to be specified into the mke2fs.conf |
| file. |
| |
| Make the smallest default journal size is big enough so that on-line |
| resizing should always work. |
| |
| Fix silly spelling error in e2fsck. (Addresses SourceForge bug: |
| #1531372) |
| |
| Fix debugfs coredump when lsdel is run without an open filesystem |
| (Addresses Debian Bug: #378335) |
| |
| Fix debugfs display bug us that bytes that have the high bit set are |
| displayed as "ec" instead of "ffffffec". |
| |
| Add support in lsattr so it will display the EXT4_EXTENTS_FL flag. |
| |
| Device mapper scanning wasn't working in the blkid library because the |
| pathnames had an extra "/dev" when they were being probed. |
| |
| Add GFS/GFS2 support to the blkid library. |
| |
| Fix blkid support of empty FAT filesystem labels. |
| |
| Avoid recursing forever (or for a long time) when the blkid library |
| searches for a device and there are symlinks to directories in /dev. |
| |
| Avoid unaligned halfword access in blkid when accessing FAT |
| superblocks, as this will cause Sparc/Solaris systems to throw a |
| SIGBUS error. |
| |
| The latest devmapper libraries requires pthreads, add -lpthreads to |
| the static link libraries for e2fsck.static if devmapper is enabled. |
| (Addresses Debian bug: #388718) |
| |
| Improve the (non-installed, for experts only) findsuper program by |
| printing the uuid and label from the superblocks, as well as the |
| starting and ending offsets of the filesystem given the information in |
| the superblock. Omit by default printing superblocks that are likely |
| found in located in an ext3 journal unless an explicit -j option is |
| given. |
| |
| Updated Spanish, French and Dutch translations and added Catalan |
| translation. (Addresses Debian bug: #411562) |
| |
| Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when |
| determining a partition's size, since binary searching to determine |
| the device doesn't work on FreeBSD. |
| |
| Documentation about UUID's is available in enough places, and it's |
| awkward to deal with debian-legal's insanities. So I'm caving in the |
| "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we |
| don't have do the dfsg tarball. Also remove the rule that only tried |
| to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch |
| e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107) |
| |
| Fix the info-dir line so that the menu name does not contain a .info |
| prefix. First of all, it's ugly, secondly, it causes the install-info |
| command to fail to remove the com_err info file from the |
| /usr/share/info/dir file when the comerr-dev package is removed and |
| purged. (Addresses Debian Bug: #401711) |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages. |
| (Addresses Debian Bug: #369761, #373004, #379695) |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs #389554, #390664, #413208, #419605, |
| #408352, #415560, #399155) |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| E2fsck now supports the %It expansion when printing a problem report. |
| It will print the type of the inode in the problem context. |
| |
| Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet |
| (Addresses Sourceforge Bug: #1565561) |
| |
| Remove unused variables and other lint/gcc -Wall cleanups |
| |
| Add check to ext2fs_get_device_size() so it will return EFBIG for for |
| filesystems contained in regular files where the filesystem image size |
| is returned by stat64(). |
| |
| Set local environment variables to C so mk_cmds and compile_et always |
| work. (Addresses SourceForge Bug: #1532177) |
| |
| Added the 64-bit byte swapping function ext2fs_swab64(). |
| |
| Added two new helper functions to prevent 2**31/2**32-1 overflow |
| problems: ext2fs_div_ceil() and e2p_percent(). |
| |
| Create new ext2fs library inline functions ext2fs_group_first_block() |
| and ext2fs_group_last_block() in order to calculate the starting and |
| ending blocks in a block group. |
| |
| Create the generated files read-only to remind developers not to edit them. |
| |
| Add support for autoconf 2.60 (with backwards compatibility for older |
| versions of autoconf). |
| |
| Added an "make rpm" target to top-level Makefile |
| |
| Added various FreeBSD portability fixes. |
| |
| Exclude mercurial files from the RPM build tree to speed up copy/build. |
| |
| Use root_sysconfdir to define the locations of mke2fs.conf and |
| e2fsck.conf instead of using a hard-coded /etc pathname. |
| |
| Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times. |
| |
| Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files. |
| |
| If diff -u is supported, use it to report test failures. |
| |
| Updates/improvements to RPM spec file |
| |
| Add on-disk format definitions for the following new features: |
| EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM, |
| EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT, |
| EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE |
| |
| Add a new make target "checked-failed" in the tests directory which |
| reruns any failed tests |
| |
| Update draft-leach-uuids-guids-01.txt with rfc4122.txt |
| |
| Fix miscellaneous bugs reported by Coverity: Dead code, potential nul |
| pointer dereferences, memory leaks, etc. None were security-criticial |
| problems. |
| |
| Fix up usage and decrement error messages in the test_icount program |
| |
| Add debugging code to the com_err library; if the environment variable |
| COMERR_DEBUG is set to 1, print out debugging messages as error tables |
| are added and removed from the com_err library. If the |
| COMERR_DEBUG_FILE environment variable is set (and the process is not |
| setuid) the debugging messages may be redirected to a file. |
| |
| Change all of the e2fsprogs programs to use the newer add_error_table() |
| and remove_error_table() interfaces instead of the much older |
| initialize_*_error_table() function. |
| |
| Add TDB support into the ext2fs library. This allows us to have a |
| guaranteed library we can count on always being present so we can |
| store data in an on-disk database. |
| |
| Add support for using TDB to store the icount data, so we don't run out |
| of memory when checking really large filesystems. |
| |
| Change the regression test suite so that it skips empty test directories. |
| |
| Define the l_i_iversion field in ext2_inode. The l_i_version field is |
| now defined from the old l_i_reserved1 field in the ext2 inode. This |
| field will be used to store high 32 bits of the 64-bit inode version |
| number. |
| |
| Add Makefile production rule for e2fsprogs.spec in case it gets |
| deleted. |
| |
| Add new function profile_get_uint() to allow for a clean way to fetch |
| unsigned integers from the context. |
| |
| Add test to make sure the ext2 superblock structure is 1024 bytes. |
| |
| Fix typo in name of f_dup4 regression test |
| |
| Add new function blkid_gc_cache() which performs a garbage collection |
| pass on the /etc/blkid.tab file. |
| |
| The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In |
| general, only e2fsck (after the filesystem is clean), tune2fs, and |
| resize2fs should change the backup superblocks by default. Most |
| callers of ext2fs_open() should not be touching any superblock fields |
| which require the backups to be touched. |
| |
| Add new function to libext2fs, ext2fs_default_journal_size(), which |
| returns the default journal size. |
| |
| |
| E2fsprogs 1.39 (May 29, 2006) |
| ============================= |
| |
| Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems |
| between 2**31 and 2**32 blocks. |
| |
| Change mke2fs to use /etc/mke2fs.conf as a configuration file to |
| configure the filesystem features, blocksize, and inode_ratio for |
| different filesystem types. |
| |
| Mke2fs will now create filesystems hash trees and on-line resizing |
| enabled by default, based on the new /etc/mke2fs.conf file. |
| |
| The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the |
| filesystem device node in exclusive mode to prevent accidents by |
| system administrators. In the case of resize2fs and mke2fs, it will |
| only use exclusive mode if the filesystem is not mounted. |
| |
| Fixed a bug in mke2fs which caused it to to fail when creating the |
| resize inode for large filesystems. (Addresses Debian Bug #346580) |
| |
| When allocating space for the RAID filesystems with the stride |
| parameter, mke2fs will now place each portion of the group's inode |
| table right up after the superblock (if present) in order to minimize |
| fragmentation of the freespace. |
| |
| Speed up mke2fs and e2fsck by writing inode and block bitmaps more |
| efficiently by writing the inode and block bitmaps in one pass, thus |
| reducing the number of disk seeks required. |
| |
| Add support for on-line resizing to resize2fs. |
| |
| Fix blkid library so that logic to determine whether or not a device's |
| cached information in /etc/blkid.tab needs to be verified or not |
| doesn't get confused by a system clock which is insane (for example, |
| if the battery is dead on a Macintosh running PPC Linux. (Addresses |
| Red Hat Bug: #182188) |
| |
| The blkid library will now store the UUID of the external journal used |
| by ext3 filesystems, so that in the future, the userspace mount binary |
| can use this to find the location of the external journal and pass |
| this information to the kernel. |
| |
| E2fsck will now consult a configuration file, /etc/e2fsck.conf to |
| control how various options should be handled. See the e2fsck.conf |
| man page for more details. (Addresses Debian Bug: #150295) |
| |
| E2fsck now prints an explanatory message when delaying a filesystem |
| check when the system is running on battery. (Addresses Debian Bug: |
| #350306) |
| |
| E2fsck will detect if the superblock's last mount field or last write |
| field is in the future, and offer to fix if so. (Addresses Debian Bug |
| #327580) These problems will be fixed automatically in preen mode |
| since Debian's boot sequence bogusly doesn't set the time correctly |
| until potentially very late in the bootup process, and this can cause |
| false positives which will cause users' systems to fail to boot. |
| (Addresses Debian Bugs #343662 and #343645) |
| |
| E2fsck now checks to see if the superblock hint for the location of |
| the external journal is incorrect, and if so, offer to update it. |
| (Addresses Debian Bug: #355644) |
| |
| Fix e2fsck from segfaulting on disconnected inodes that contain one or |
| more extended attributes. (Addresses Debian Bug: #316736, #318463) |
| |
| E2fsck will stop and print a warning if the user tries running a |
| read/write badblocks test on a read-only mounted root filesystem. |
| |
| Fix a memory leak in e2fsck's error paths. (Thanks to Michael |
| C. Thompson for pointing these out; they were originally found using |
| Coverity.) |
| |
| When resizing a file containing a filesystem, resize2fs will expand or |
| truncate a file as necessary. (Addresses Debian Bug: #271607) |
| |
| Resize2fs will now automatically determine the RAID stride parameter that |
| had been used to create the filesystem, and use that for newly created |
| block groups. The RAID stride parameter may also be manually specified |
| on the command line using the new -S option to resize2fs. |
| |
| Fix mke2fs so that it correctly creates external journals on |
| big-endian machines (such as a S/390). |
| |
| Fix a bug in the e2p library which could cause dumpe2fs to (rarely) |
| fail to print out the journal or hash seed UUID. (Thanks to Guillaume |
| Chambraud for pointing this out.) |
| |
| Dumpe2fs will now print the size of the journal (if present). |
| |
| Fix debugfs's set_inode_field command so it can properly set the frag, |
| fsize, uid_high, gid_high, and author fields in the inode instead of |
| silently failing, and so that setting the i_size actually sets i_size |
| correctly. |
| |
| Add a new debugfs command, set_current_time, which sets fs->now so |
| that regression test suites can repeatedly modify the filesystem's |
| last_write fields. |
| |
| Fix a bug in debugfs's icheck which would incorrectly report the owner |
| of an extended attribute block. |
| |
| Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a |
| print a usage message when an illegal option character is given. |
| |
| Fix debugfs's dump_unsued command on filesystems with a 64k blocksize |
| so it won't core dump. (Addresses SourceForge bug #1424311) |
| |
| Fix mklost+found so that it creates a full-sized directory on |
| filesystems with larger block sizes. |
| |
| Fix a file descriptor leak in blkid library. |
| |
| Fix a display bug in "badblocks -sv" so that the done message properly |
| clears the block number at the end of the test. (Addresses Debian Bug |
| #322231) |
| |
| Allow fractional percentages to the -m option in mke2fs and tune2fs |
| (Addresses Debian Bug: #80205) |
| |
| Use fstat/fstat64 in getsize.c if the the target is a regular file, |
| instead of attempting to do a binary search. Fix some fd leaks in |
| error cases. |
| |
| Add support for device mapper library to the blkid library to ensure |
| that the "best" (i.e., leaf) device is probed by the blkid library. |
| |
| Fix the blkid library so that it notices when an ext2 filesystem is |
| upgraded to ext3. |
| |
| Improve the blkid's library VFAT/FAT detection; it now understands |
| labels stored in the root directory, and is more paranoid about |
| checking the FAT superblock values. |
| |
| Fixed a fd leak in the uuid library which was causing problems for the |
| LVM tools. (Addresses Debian Bug: #345832) |
| |
| Add support for the reiser4 and software suspend partitions to the |
| blkid library. Also add support for extract the label from iso9660 |
| filesystems. |
| |
| Fix a compile_et bug which miscount the number of error messages if |
| continuations are used in the .et file. |
| |
| Add extra sanity checks to protect users from unusual cirucmstances |
| where /etc/mtab may not be sane, by checking to see if the device is |
| reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug |
| #319002) |
| |
| Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian |
| Bug: #343149, #341911, #300871, #316604, #316782, #330789) |
| |
| Fix use-after-free bug in e2fsck when finishing up the use of the |
| e2fsck context structure. |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages and |
| documentation. (Addresses Debian Bugs: #329859, #322188, #316811, |
| #312515, #351268, #357951, #347295, #316040, #368392, #368393, #368394, |
| #368179) |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs #317862, #320389, #290429, #310950, |
| #310428, #330737, #330736, #329074, #356293, #360046, #366017, #364516, |
| #362544, #362970) |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| Update config.guess and config.sub to latest version (2006-02-23) from |
| FSF. |
| |
| Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian |
| Bugs: #360661, #360317) |
| |
| Fixed the Makefile so that they work correctly on newer versions of |
| GNU make (i.e., 3.81). |
| |
| Add valgrind support to the regression test suites, and eliminate |
| false positives from valgrind. |
| |
| Add a regression test suite for the blkid library. |
| |
| Fix a fencepost error in resize2fs caught by valgrind. |
| |
| Fix compiler warnings about missing memcpy prototypes. |
| |
| We no longer have the sparc assembly code in the header file any more, |
| so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would |
| break compiles on the sparc architectures when using gcc. |
| |
| In the libext2fs library, add the new field fs->now which if non-zero |
| is used instead of the system time when setting various filesystem |
| fields (last modified time, last write time, etc.) |
| |
| Fix gcc 4.01 complaints by adding a missing #include <string.h> to |
| ext2fs.h which is needed since the inline functions use memcpy(). |
| (Addresses Sourceforge Bug #1251062) |
| |
| Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in |
| the build system when building files in the util directory which are |
| needed during the build process. This avoids potential problems when |
| cross-compiling and some of the options specified in CFLAGS or LDFLAGS |
| are not recognized as valid by the host compiler. (Addresses |
| Sourceforge Bug #1261547) |
| |
| Clean up the blkid library by making the superblock and generic i/o |
| functions to be more generic. Clean up interface to the probe |
| function, and fix memory leak. Finallly, remove an unneeded reference |
| to probe.h in the lib/blkid/resolve.c |
| |
| Add an ext2fs_read_bb_FILE regression test to confirm proper detection |
| of invalid block #'s. |
| |
| The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to |
| indicate that the the function read/writes the memory location. |
| |
| Fix various gcc -Wall complaints. |
| |
| Add a dependency to make sure that the subdirectories are created |
| before creating all of the object files, in order to address parallel |
| build problem in the library Makefiles. (Addresses Sourceforge Bug: |
| #1261553) |
| |
| Add $(LDFLAGS) to the command line argument when generating an ELF or |
| Solaris shared library, to allow cross-compile and other builds that |
| might need to specify -L paths to needed libraries. (Addresses |
| Sourceforge Bug #1261549) |
| |
| Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially |
| intended for testing purposes. It allows an ext2/ext3 developer to |
| create very large filesystems using sparse files where most of the |
| block groups are not initialized and so do not require much disk |
| space. Eventually it could be used as a way of speeding up mke2fs and |
| e2fsck for large filesystem, but that would be best done by adding an |
| RO_COMPAT extension to the filesystem to allow the inode table to be |
| lazily initialized on a per-block basis, instead of being entirely |
| initialized or entirely unused on a per-blockgroup basis. |
| |
| Fix backwards compatibility so e2fsprogs will better compile on Linux |
| 2.0.35 systems. |
| |
| Make test scripts more robust against locale-related environment variables |
| |
| Fix type warning problem with sizeof() in ext2fs_open2(). |
| |
| Fix type warning problem with time_t in debugfs. |
| |
| |
| E2fsprogs 1.38 (June 30, 2005) |
| ============================== |
| |
| Fix blkid's test programs (built with "make check") compile correctly |
| even without "configure --enable-blkid-debug". |
| |
| Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict |
| type aliasing rules on newer gcc compilers. (Addresses Red Hat |
| Bugzilla ##161183.) |
| |
| Fix com_err library to make it more compatible with recent changes |
| made to the com_err library in MIT Kerberos V5 version 1.4. |
| (Addresses Sourcefroge Bug #1150146) |
| |
| General cleanup of messages printed by e2fsprogs programs for grammar, |
| consistency, and to make life easier for translators. Fixed a few |
| strings containing English that had not been marked as needing |
| translations. Removed strings that do not need to be translated, to |
| make life easier for translators. |
| |
| Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to |
| test to see if a device appears to be in use instead of just relying |
| on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594). |
| |
| Fix portability problem in the filefrag program affecting platforms |
| where the size of an integer is smaller than the size of a long. |
| (Addresses Debian Bug #309655) |
| |
| Mke2fs will now use a larger journal by default for filesystems |
| greater than 4GB. (128 MB instead of 32MB). |
| |
| Mke2fs will refuse to create filesystems greater than 2**31-1 blocks, |
| unless forced. This is to avoid signed vs. unsigned kernel bugs in |
| block numbers that still need to be fixed. |
| |
| The blkid program has a new option which will more efficiently search |
| for device when it is known (or expected) that only one matching |
| device will be found in the system, such as when doing a lookup by |
| UUID. |
| |
| Debian's e2fsprogs-specific initrd fragment will avoid including |
| unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD |
| and LD_LIBRARY_PATH, and filtering out libraries found in |
| /etc/ld.so.preload. (Addresses Debian Bug: #304003) |
| |
| Fixed a potential portability issue in the blkid programs for |
| architectures where the char type is unsigned. (Addresses Sourceforge |
| Bug: #1180585) |
| |
| Fix a bug in filefrag so that it doesn't falsely count an extra |
| discontinuity when the first block found is an indirect block. |
| (Addresses Debian Bug #307607). |
| |
| Fix blkid's recognition of cramfs filesystems, and enhance it to be |
| able to handle cramfs labels. |
| |
| Fix debugfs's stat command to not core dump when a filesystem is not |
| open. |
| |
| Fix e2fsck's handling of error conditions caused by the resize inode |
| claiming blocks that are also used by other inodes, a filesystem |
| corruption which was commonly caused by a bug in Fedora Core 3's |
| resize2fs program. |
| |
| Fixed bug in filefrag which caused it to fail on non-ext2/3 |
| filesystems. (Addresses Debian Bug: #303509) |
| |
| If the superblock last mount time indicates that the system clock may |
| not be accurate, then e2fsck will omit checking inodes' deletion time |
| field for indications of a potential corrupted orphaned inode list. |
| (Previously e2fsck only ommited these LOW_DTIME checks when the |
| superblock's last write time looked insane.) |
| |
| Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs. |
| (Addresses Debian bug #302200) |
| |
| Make the blkid library more paranoid about being run from setgid |
| programs, and to use __secure_getenv() from libc if it is available. |
| |
| Fixed spelling mistakes, typos, and otherwise clarified man pages. |
| (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593 |
| and Sourceforge Bug: #1189803) |
| |
| Updated and fixed translations. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |

| |
| Programmer's notes: |
| ------------------- |
| |
| Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been |
| changed to take an unsigned int for the bit number. Negative bit |
| numbers were never allowed (and didn't make any sense), so this should |
| be a safe change. This is needed to allow safe use of block numbers |
| greater than or equal to 2**31. |
| |
| The compile_et program will avoid recreating generated foo_err.c and |
| foo_err.h files if no changes are necessary. The compile_et program |
| will also atomically replace these files to avoid a potential parallel |
| build race problem on SMP systems. (Addresses Sourceforge Bug: |
| #1157933) |
| |
| Added a new function to the blkid library, blkid_probe_all_new(), |
| which only probes newly added disk devices, and change |
| blkid_find_dev_with_tag() to use this function so that when a |
| requested tag is not found, devices that were previously not checked |
| are searched before searching all devices in the system. |
| |
| Added new functions to the blkid library, blkid_dev_set_search() and |
| blkid_dev_has_tag(). |
| |
| E2fsck's problem strings can now use @m and @n as abbrevations for |
| "multiply-claimed" and "invalid", respectively. |
| |
| The e2fsprog.pot file now has an explanation of how the @-expansion |
| and %-expansion works, and strings in e2fsck/problem.c which contain @ |
| characters now have comments in e2fsprogs.pot with the @-expansion to |
| make life easier for translators. |
| |
| Fixed missing return values in the ext2fs library which could cause it |
| to return random garbage in certain error conditions. |
| |
| Allow the current time to be overriden via the E2FSCK_TIME environment |
| variable for use in regression tests. |
| |
| The test scrpit driver program now exits with a non-zero status if |
| there any of its test that it ran failed. |
| |
| Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge |
| Bug: #1157933) |
| |
| Fixed "make check" so that it compiles correctly even when e2fsprogs' |
| header files have not be installed in the system include directories. |
| (Addresses Sourceforge Bug: #1180572) |
| |
| Fixed gcc -Wall nits. |
| |
| |
| E2fsprogs 1.37 (March 21, 2005) |
| =============================== |
| |
| Add support for checking the validity of Extended Attributes stored in |
| inodes to e2fsck. |
| |
| Add support for dumping the contents of large inodes to debugfs, |
| including the extended attributes stored in inodes. |
| |
| Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that |
| when we create a new inode we make sure that the extra information in |
| the inode (any extra fields in a large inode and any ea-in-inode |
| information) is initialized correctly. This can take place when |
| mke2fs creates the root and lost+found directory, when e2fsck creates |
| a new root inode or a new lost+found directory, and when the user uses |
| the debugfs write, mknod, or mkdir commands. Otherwise, the newly |
| create inode could inherit garbage (or old EA information) from a |
| previously deleted inode. |
| |
| Fixed a bug in e2fsck so it would notice if a file with an extended |
| attribute block was exactly 2**32 blocks, such that i_blocks wrapped |
| to zero. |
| |
| Added support to filefrag to detect files which are using the new |
| experimental file extents format, and use the non-ext2 algorithm in |
| that case. Fixed a bug to avoid reporting a false discontinuity if |
| there is one or more unallocated blocks at the beginning of a file. |
| |
| Duplicated a check for noticing whether or not the number of blocks |
| (given a certain blocksize) is greater than 2**32 when the |
| BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This |
| allows mke2fs to automatically use a larger blocksize when creating a |
| filesystem on a very large device when run on systems that do not |
| support BLKGETSIZE64. |
| |
| Fix the I18N build which was broken in e2fsprogs 1.36 because the |
| build system had been switched to treat the .gmo files as shipped |
| files (for backwards compatibility with systems that have older GNU |
| I18N tools installed), but the gen_tarball.in script was still |
| removing the .gmo files from the official source distribution. |
| |
| Fixed various Debian packaging issues --- see debian/changelog for |
| details. (Addresses Debian Bugs ##296769, #299341) |
| |
| Programmer's notes: |
| ------------------- |
| |
| Added new functions to the e2p library which convert between a string |
| and os_type: e2p_os2string() and e2p_string2os(), and used them to |
| make the generated binaries more compact. |
| |
| Fixed a compile-time error on Darwin systems. |
| |
| Cleaned up the lib/ext2fs Makefile slightly. |
| |
| |
| E2fsprogs 1.36 (February 4, 2005) |
| ================================= |
| |
| All of the patches that were applied to Fedore Core 3's |
| e2fsprogs-1.35-11.2 have been integrated, although sometimes with a |
| lot of bug fixes first. Users of Fedora Core 3 are strongly |
| encouraged to upgrade to e2fsprogs 1.36 as soon as possible. |
| |
| Add support for filesystem with the online resizing via resize inode |
| feature. Fixed numerous bugs from the Fedora patches. The Fedora |
| patches also didn't bother to do any consistency checking on the |
| resize inode, or add any tests to the regression test suite. The "-R |
| resize=4g" option to mke2fs was a no-op in the Fedora patches, despite |
| being listed in mke2fs's usage message. All of these shortcomings |
| have been corrected. |
| |
| E2fsck can also also fix filesystems trashed by Fedora's resize2fs |
| program. In order to do this, the user must run the commands: |
| |
| debugfs -w /dev/hdXXX -R "features ^resize_inode" |
| e2fsck -f /dev/hdXXX |
| |
| Optionally, the ext2prepare command can be used to re-enable online |
| resizing after the filesystem has been fixed. |
| |
| The fsck program will now accept an optional filedescriptor argument |
| to the -C option. (The Fedora version of this patch would sometimes |
| cause fsck to ignore a parameter on fsck's command line in some rare |
| cases, sigh.) |
| |
| Make sure e2fsprogs doesn't write garbage into the reserved portion of |
| large inodes. |
| |
| Make sure resize2fs releases the blocks belonging to the old inode |
| table blocks when moving the inode table. (Addresses Debian Bug: |
| #290894) |
| |
| Skip the r_resize_inode test if resize2fs is not compiled (due to |
| configure --disable-resizer) |
| |
| E2fsck now checks the summary filesystem accounting information, and |
| if any of the information is obviously wrong, it will force a full |
| filesystem check. (Addresses Debian Bug #291571) |
| |
| Fix e2fsck to not complain when the resize_inode feature is enabled, |
| s_reserved_gdt_blocks is zero, and there is no DIND block allocated in |
| the resize inode. |
| |
| Fix e2fsck to note delete symlinks that contain an extended attribute |
| after the ext_attr feature flag has been cleared. (Addresses Red Hat |
| Bugzilla #146284). |
| |
| Add new utility program, copy_sparse.c, which is very useful |
| for dealing with large sparse files (such as e2image files). |
| |
| Add support for jnl_blocks[] for debugfs's set_super_value. |
| |
| Fix filefrag so that it works correctly with sparse files. |
| |
| Filefrag -v will print first and last blocks. |
| |
| Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs |
| and dumpe2fs. |
| |
| Add mke2fs support so that it can support filesystems larger than 4TB |
| automatically, by retrying with a 4k blocksize if the device size is |
| too big to be expressed using a 1k blocksize. (Addresses Sourceforge |
| bug #1106631) |
| |
| Change blkid to test for NTFS first because Windows sometimes doesn't |
| clear enough of the parition to confuse the probing routines into |
| thinking the old filesystem type is still valid. (Addresses Debian |
| Bug #291990) |
| |
| Add support for swap partition label and uuid's in the blkid library. |
| |
| Add support to the blkid library to recognize Oracle ASM volumes. |
| |
| Make blkid -t display all devices that match the specified criteria, |
| not just the first one, and work more consistently when the blkid |
| cache file is not available or set to /dev/null. (Addresses Debian |
| Bug #290530 and #292425) |
| |
| Badblocks will now correctly display block numbers greater than |
| 999,999,999 in its progress display. |
| |
| The tune2fs program will not allow the user from setting a ridiculous |
| number of reserved blocks which would cause e2fsck to assume the |
| superblock was corrupt. E2fsck's standards for what is a ridiculous |
| number of reserved block has also been relaxed to 50% of the blocks in |
| the filesystem. |
| |
| The blkid library will return vfat in preference to msdos, and ext3 in |
| preference to ext2 (if the journalling flag is set) so that mount will |
| do the right thing. (Addresses Debian bug #287455) |
| |
| Mke2fs will now use the -E option for extended options; the old -R |
| (raid options) option is still accepted for backwards compatibility. |
| Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707) |
| |
| Mke2fs will now accept a size in megabytes, gigabytes, and other units |
| (via "32m" or "4g" on the command line) if the user finds this more |
| convenient than specifying a block count. |
| |
| Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode |
| cache conherency problem. |
| |
| Debugfs now supports a new command, set_inode_field, which allows a |
| user to manually set a specific inode field more conveniently, as well |
| as set entries in the indirect block map. |
| |
| Debugfs's set_super_value command has been enhanced so that the user |
| can set most superblock fields, including the date/time fields and |
| some of the more newsly added superblock fields. |
| |
| E2fsprogs programs now accept an offset to be passed to the file |
| specifiers, via the syntax: "/tmp/test.img?offset=1024". |
| |
| E2fsprogs programs will now accept blocksizes up to 65536; kernel |
| support on the x86 doesn't exist for now, but it can be useful on |
| other architectures with page sizes greater than 4k. There are 2.6 |
| kernel patches out there which enable this, but they are of this |
| writing still experimental. |
| |
| The e2image command now takes the -s option which will scramble |
| directory entries for raw image files. |
| |
| Fix a file descriptor leak in the filefrag program. |
| |
| Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not |
| present. |
| |
| Fix bug in debugfs where kill_file would lead to errors when deleting |
| devices and symlinks. (Sourceforge Bugs #954741 and #957244) |
| |
| Fix bug in the blkid library when detecting the ocfs1 filesystem |
| |
| Remove obsolete EVMS 1.x and a.out DLL support. |
| |
| E2fsck will attempt to recover from a journal containing illegal blocks. |
| |
| Fixed two potential ordering constraint problems in e2fsck which might |
| cause the filesystem to be corrupted if e2fsck is interrupted during a |
| (extremely narrow) race window. Thanks to Junfeng Yang from the |
| Stanford Metacompilation group for pointing this out. |
| |
| Fixed bug in e2fsck where it would not accurately detect whether or |
| not the system is running on adaptor if the ACPI device representing |
| the AC adapter didn't correspond to the what was used on IBM |
| Thinkpads. |
| |
| Change e2fsck to accept directories greater than 32MB. |
| |
| Fix e2fsck so that a checkinterval of zero disables a time-based check |
| of the filesystem. |
| |
| Debugfs will check the DEBUGFS_PAGER enviroment variable in preference |
| to the PAGER environment variable. (Addresses Debian Bug #239547) |
| |
| Tune2fs will not mark rewrite the superblock if the feature bitmasks |
| are not modified. |
| |
| The debugfs program will set the filetype information when creating a |
| link. |
| |
| Add debugfs -d option to use a separate source of data blocks when |
| reading from an e2image file. |
| |
| Add e2image -I option which allows the e2image metadata to be |
| installed into a filesystem. |
| |
| Fixed bug in the badblocks program which caused "done" to always |
| appear in english even when a translation was available. (Addresses |
| Debian Bug #252836) |
| |
| The blkid program has a new option -o which controls the output format |
| of the blkid program; this is makes blkid more convenient to use in |
| shell scripts. |
| |
| Fix a minor bug in uuid library, which was not using the full 14 bits |
| of clock sequence when generating UUID's. |
| |
| Fix a Y8.8888K problem in the uuid library. |
| |
| Logsave now creates a new session id for itself to avoid getting |
| killed by init whan transitioning between init levels. |
| |
| Change the licensing of the UUID library to be the 3-clause BSD-style |
| license; this allows Apple to use the uuid library in Darwin. |
| |
| Add ocfs and ocfs2 probe support into the blkid library. |
| |
| Fix a memory and file descriptor leak in the blkid library. |
| |
| The blkid library will revalidate the device if the system time is |
| earlier than last verification time of the device, since that |
| indicates that the system time is probably nottrustworthy. |
| |
| The blkid library will override the default location of the blkid.tab |
| file by the BLKID_FILE environment variable, if it is available. |
| |
| Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6. |
| |
| Add various portability fixes for lame new versions of glibc, Darwin |
| and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian |
| Bugs #239934, #264630, #269044, #255589, #289133) |
| |
| Add support for Windows 9x/NT under Cygwin. |
| |
| Updated and clarified various man pages. (Addresses Debian Bugs #236383, |
| #241940, #238741, #242995, #256669, #268148, #256760, #273679) |
| |
| Updated and fixed translations. (Addresses Debian bugs #244105, #262836) |
| |
| Update the rpm spec files so that it works better with Fedora core 2 |
| and RH9. |
| |
| Fixed various Debian packaging issues (see debian/changelog). In |
| particular, fixed the Debian initrd scripts. (#241183, #248050, |
| #253595, #247775) |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fixed various gcc -Wall warnings. |
| |
| The uuid library now has new functions uuid_unparse_upper() and |
| uuid_unparse_lower() which forces the case of the hex digits to be |
| upper case, or lower case. |
| |
| The build process has been speeded up by enhancing the subst program |
| to update the modtime on the generated files even when the generated |
| file hasn't changed. |
| |
| The uuid library now uses C99 stdint.h types instead of custom types. |
| |
| Updated config.guess and config.sub with newer versions from the FSF. |
| |
| Removed out of date .cvsignore files from the source distribution. |
| |
| The ext2fs_unlink() function will return an error if both the name and |
| inode number are unspecified, to avoid doing something surprising |
| (such as unconditionally deleting the first directory entry). |
| Directory entries are now deleted by coalescing them with the previous |
| directory entry if possible, to avoid directory fragmentation. This |
| is not an issue with the e2fsprogs suite, but may be a problem for |
| some of the users of libext2fs, such as e2tools. |
| |
| Add support for version numbers of the form "1.36-rc1". |
| |
| Fix build of mke2fs.static. |
| |
| Add basic ext2fs library support for large (EA in inode) inodes. |
| |
| The test_io mechanism can now abort after n reads or writes to a |
| particular block. The block is specified by TEST_IO_BLOCK environment |
| variable, and the read/write count by the TEST_IO_READ_ABORT and |
| TEST_IO_WRITE_ABORT environment variables. The block data is now only |
| dumped if the 0x10 bit is set in TEST_IO_FLAGS. |
| |
| UUID_DEFINE() in the uuid library now creates a static variable, with |
| __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can |
| be used in header files. |
| |
| Add support for the install-strip and install-shlibs-strip targets, as |
| suggested by the GNU coding guielines. "make install" no longer |
| strips the binaries which are installed. |
| |
| Remove support for the --enable-old-bitops configure option which was |
| only for very old sparc systems. |
| |
| Remove support for --enable-clear-htree; this was only needed during |
| the early development of the htree patch. |
| |
| Use Linux-kernel-style makefile output so it is easier to see compiler |
| warnings. |
| |
| Update gettext files to version 0.14.1. |
| |
| Update to use autoconf 2.5x. |
| |
| Improved support for compiling e2fsprogs under dietlibc. |
| |
| Make e2fsprogs portable to Solaris and FreeBSD systems. |
| |
| Add blkid_verify(), blkid_get_library_version(), and |
| blkid_parse_version_string() functions to the blkid library. |
| |
| Add pkg-config files for e2fsprogs's libraries. |
| |
| Fix "make uninstall" to so that it removes everything that is installed. |
| |
| Add a configure --enable-maintainer-mode option which enables the |
| makefile rules to rebuild the configure script from configure.in, and |
| to reubuild the .gmo files in po directory. |
| |
| Drop the sparc assembly bitwise operations; it's less efficient |
| than the GCC 3.4 compile code and triggers compiler warnings on |
| sparc64. Thanks to Matthias Andree for his analysis and suggestions. |
| (Addresses Debian Bug #232326) |
| |
| |
| E2fsprogs 1.35 (February 28, 2004) |
| ================================== |
| |
| E2fsck has a new -k option, which in conjunction with the -c options, |
| preserves the existing badblocks list. |
| |
| Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d. |
| |
| E2fsprogs will now deal correctly with symlinks that contain |
| extended attribute information, which can be created using SE Linux. |
| (Addresses Debian Bug #232328) |
| |
| Remove a double longjump into an invalid stack frame bug in e2fsck. |
| (This was during an abort sequence, which normally worked on Linux and |
| caused a core dump on other operating systems.) |
| |
| Fix NLS bug in e2fsck, by avoiding trying to expand an empty string |
| (the NLS library will replace "" with the .po header information). |
| |
| Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core |
| dump due to a division by zero error. (Addresses Debian bug #207082) |
| |
| Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem |
| when reconnecting a directory requires creating a lost+found |
| directory. (Addresses Debian bug #219640). |
| |
| Fixed a bug where e2fsck would bomb out if a journal needed to be |
| replayed when using an alternate superblock. |
| |
| E2fsck will give an extra grace period before actually forcing a check |
| if the laptop is running on battery. The next time fsck runs while |
| the system is on the AC mains, or after the grace period is exceeded, |
| the filesystem will be checked. (Addresses Debian bug #205177) |
| |
| E2fsck will inform the user when there are 5 or fewer mounts before a |
| filesystem check will be forced. (Addresses Debian bug #157194) |
| |
| Fix e2fsck's handling of corrupted indirect blocks in the bad block. |
| We now correctly handle the case where there is an overlap between a |
| block group descriptor or a superblock and a bad block indirect block. |
| In the case where the indirect block is corrupted, we now suggest |
| "e2fsck -c". |
| |
| Fix byte swap bugs in e2fsck that caused the journal backup location |
| in the superblock and symlinks created by SE Linux to be cleared |
| by e2fsck on big-endian machines. (Addresses Debian bug #228723) |
| |
| E2fsck -c now replaces the current list of bad blocks with the ones |
| found by badblocks. |
| |
| Fix bugs in e2fsck and tune2fs which could cause a core dump if a |
| non-existent LABEL or UUID specifier is to e2fsck or tune2fs. |
| |
| Fix a potential bug in e2fsck which could cause it to core dump when |
| trying to print the location of the backup superblock. |
| |
| Protect against a potential core dump in e2fsck when printing a |
| message about backup superblocks. |
| |
| Add support for backing up the journal inode location in the |
| superblock. E2fsck will automatically save the journal information in |
| the superblock if it is not there already, and will use it if the |
| journal inode appears to be corrupted. ext2fs_add_journal_inode() |
| will also save the backup information, so that new filesystems created |
| by mke2fs and filesystems that have journals added via tune2fs will |
| also have journal location written to the superblock as well. |
| Debugfs's logdump command has been enhanced so that it can use the |
| journal information in the superblock. |
| |
| E2fsck will now update all superblocks when moving the journal inode. |
| |
| Shrink the size of the e2fsck executable by moving some initialized |
| variables to the BSS segment. |
| |
| E2fsck will avoid printing the ^A and ^B characters which bracket the |
| progress bar when stdout and stdin are a tty device instead of a pipe |
| to another program. (Addresses Debian bug #204137) |
| |
| Debugfs's mkdir command will automatically expand the directory if |
| necessary. (Addresses Debian Bug: #217892) |
| |
| Fixed a bug in debugfs so that copying a file from /dev/null uses the |
| correct mode bits. (Addresses Debian Bug: #217456) |
| |
| If the environment variables DEBUFS_PAGER and PAGER are not set, |
| debugfs now searches for the appropriate pager to use, beginning with |
| /usr/bin/pager, and then falling back to 'more' and 'less'. |
| (Addresses Debian bug #221977) |
| |
| Debugfs will now support 2.6 device numbers where the major or minor |
| number may be larger than 255. (Addresses Sourceforge bug #865289) |
| |
| Fix debugging printf in resize2fs. (Addresses Debian Bug #271605) |
| |
| Chattr now stops processing options when it sees '--'. (Addresses |
| Debian bug #225188) |
| |
| Fix regression tests so they work correctly when e2fsprogs is compiled |
| with configure --disable-htree. |
| |
| Fix bug in uuid library when there is no network card and the library |
| is generating a time-based uuid. The random MAC address was not |
| correctly generated to be a multicast address. |
| |
| Add compile_et extensions from Heimdall that were missed the first time |
| around. |
| |
| Fix bug in badblocks when using O_DIRECT; we need to make sure that |
| we're reading from an offset which is page aligned. For read-only and |
| read-write tests, we try to recover after an error so that we can |
| continue reading on page-aligned boundaries. (Addresses Debian Bug |
| #203713) |
| |
| Badblocks now checks 64 blocks at a time instead of 16. (Addresses |
| Debian bug #232240) |
| |
| Updated and clarified various man pages. (Addresses Debian Bug |
| #206845, #222606, #214920, #232406) |
| |
| Updated and fixed translations. (Addresses Debian bugs #200086, #214633) |
| |
| Fixed various Debian packaging issues (see debian/changelog). |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fixed a build problem so that e2fsprogs would compile with the |
| --enable-profile option to configure selected. (Addresses Sourceforge |
| bug #811408) |
| |
| Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat |
| Bugzilla Bug #112448) |
| |
| Centralize code which calculates the location of the superblock |
| and block group descriptors so that it is in a single library routine. |
| |
| Added two new functions, ext2fs_file_open2() and |
| ext2fs_inode_io_intern2() which take a pointer to an inode structure. |
| |
| Fix compile_et to output the correct prototype for |
| initialize_xxx_err_table_r() in the header file. (Addresses Debian |
| bug #204332) |
| |
| In the lib/et makefile, make sure com_err.info is deleted on "make clean". |
| |
| Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if |
| present. This is for when we try stuffing an int into void * pointer. |
| |
| Fix type-punning which can cause gcc 3.x to miscompile code by getting |
| confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(), |
| and ext2fs_resize_mem() all now take a 'void *' instead of a 'void |
| **'. The EVMS code uses an ugly union approach since we don't want to |
| modify the EVMS interfaces. |
| |
| Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to |
| aid build process on systems can use invoke GNU make as "gmake". |
| |
| Added regression testing for mke2fs. |
| |
| Fixed gcc -Wall nitpicks. |
| |
| Fixed various compiler warnings. |
| |
| Add portability fixes for FreeBSD and for using fsctl under Darwin to |
| support ext2 ioctl's. |

| E2fsprogs 1.34 (July 25, 2003) |
| =============================== |
| |
| Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in |
| a tight loop while waiting for a child fsck to exit in some cases. |
| This burns CPU times which slows down the low-level filesystem check. |
| |
| Added code to mke2fs to assure that the default block size for a |
| filesystem is at least as big as the sector size of the device, if it |
| can be determined. |
| |
| Changed mke2fs and resize2fs to round the default size of a filesystem |
| to be an even multiple of the VM pagesize in order to avoid a Linux |
| kernel bug introduced when the storage of the buffer cache was moved |
| into the page cache. |
| |
| Mke2fs will warn the user when creating a filesystem with journaling |
| and a blocksize greater than 4096. (Addresses Debian bug #193773) |
| |
| Fixed a bug in resize2fs which caused it to fail on filesystems with a |
| non-empty bad block list. Resize2fs now discards any blocks on the |
| badblock list which are no longer part of the filesystem as the result |
| of a filesystem shrink. (Note: this means that shrinking and then |
| enlarging a filesystem is no longer a reversible operation; |
| information about bad blocks in the part of the filesystem which is to |
| be chopped off will be lost.) |
| |
| Changed resize2fs so the user can use prefixes to specify the units of |
| the new filesystem size (sectors, kilobytes, megabytes, or gigabytes), |
| and to make the error and informational messages explicitly display |
| the blocksize used by the filesystem, in order to avoid confusion. |
| (Addresses Debian bug: #189814) |
| |
| Added a new debugfs command, dump_unused, which dumps the contents of |
| all unused blocks to stdout. (Useful as an emergency try-to-find |
| deleted data command.) |
| |
| Added a new debugfs command, imap, which prints the location of a |
| specified inode in the inode table. |
| |
| Fixed a bug in the badblocks program which caused it to use one bit of |
| randomness in its non-destructive read/write test, instead of using a |
| full 8 bits of randomness. |
| |
| Added a new option (-t) to badblocks, which allows the user to control |
| the test pattern(s) used when checking a disk. |
| |
| The blkid probe function now more correctly detects UDF filesystems. |
| |
| Fixed a bug in the blkid library which caused it to not update its |
| cache if a filesystem changes from having a label to not having a |
| label. |
| |
| Fixed a bug in the blkid library wihch could avoid an infinite loop |
| in blkid_find_dev_with_tag() if /proc is not mounted and there the |
| /etc/blkid.tab file has not yet been created. |
| |
| Fixed the badblocks program so that the destructive read/write test |
| honors the -c option, and to use O_DIRECT when possible to avoid |
| thrashing the system block buffer cache. |
| |
| Fixed various NLS issues. |
| - Added Czech and Swedish translations |
| - Removed testing NYC translation |
| - Fixed NLS support for message abbrevations in e2fsck |
| - Remove de-utf.po, since we shouldn't have two versions using different |
| charset encodings. |
| - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to |
| simplify the statistics reporting in e2fsck. |
| |
| Changed configure.in so that its defaults for *BSD systems no longer |
| build an fsck wrapper, and not to install in /usr/local by default. |
| |
| Fixed some minor spelling errors/typo's in e2fsck and the configure |
| script. |
| |
| Fixed various Debian packaging issues (see debian/changelog). |
| |
| Updated and clarified man pages. (Addresses Debian Bug #195616) |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fix gcc -Wall nitpicks. |
| |
| Updated gettext implementation used by e2fsprogs to 0.11.5, and enable |
| NLS support by default. (Added partial workaround for gettext/Darwin |
| incompatibility problems.) |
| |
| Added full MIT KRB5 and Himdall compaibility support to the com_err |
| library and the compile_et program. (Addresses Debian bug #191900) |
| |
| Added the blkid_known_fstype() function to the blkid library, which |
| returns true if it is passed a filesystem type which is recognized by |
| the blkid probing functions. |
| |
| Improved the documentation for the blkid library. |
| |
| Added the ext2fs_get_device_sectsize() function the the ext2fs library, which |
| returns the hardware sector size of a device, if it is available. |
| |
| Added a dependency in the blkid library's .so file to the uuid |
| library, since the former uses the latter. (Addresses Debian bug |
| #194094) |
| |
| Added --with-diet-libc and --disable-evms to the configure script. |
| |
| Fixed a minor memory leak in the badblocks program. |
| |
| Fixed a portability problem in tune2fs --- not all systems have strptime(). |
| |
| Fixed a portability problem in debugfs with the use of getopt() more |
| than once. Old-style BSD, new-style BSD, and Linux C libraries all do |
| things differently. |
| |
| Add support Windows support to ext2fs_get_device_size(). |
| |
| Added (normally disabled) debugging code to the Unix I/O manager which |
| causes it to disable all userspace caching if the NO_IO_CACHE is |
| defined. |
| |
| Changed the test I/O manager so it can always be linked into e2fsck, |
| mke2fs, and tune2fs if enabled via --enable-test-io-debug to the |
| configure script. The test I/O manager will only print any debugging |
| information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment |
| variables are set, which specifies which I/O operations are logged and |
| a block number to watch, respectively. The log messages are sent to |
| stderr by default, unless a filename is specified via the |
| TEST_IO_LOGFILE environment variable. |
| |
| |
| E2fsprogs 1.33 (April 21, 2003) |
| =============================== |
| |
| Added a new utility program, logsave, which captures the output of a |
| command in a log file, even if the containing directory hasn't been |
| mounted yet (in which case the it saves the output in memory until it |
| can write out the logfile). This is useful for capturing the |
| output of fsck during the boot sequence. |
| |
| Fixed some portability problems that were causing problems under |
| the Cygwin32 environment. |
| |
| Mke2fs now interprets a negative number to the -b option as a minimum |
| block size. |
| |
| Fixed a bug in mke2fs which was incorrectly checking the argument to |
| the -g option if the default block size was used. (Addresses Debian |
| bug #188319) |
| |
| Fsck now explicitly ignores tmpfs and devpts, and it will complain if |
| it can not find filesystem checkers for jfs, reseirfs, and xfs. |
| |
| E2fsck now updates the global free block and inode counters from the |
| block group specific counters quietly. This is needed for an |
| experimental patch which eliminates locking the entire filesystem when |
| allocating blocks or inodes; if the filesystem is not unmounted |
| cleanly, the global counts may not be accurate. |
| |
| Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS |
| 2.0 is not yet supported; this only pulled in the bug fixes: fixed |
| possible hangs caused by bugs in calling waitpid, and not setting the |
| pipe to non-blocking mode; also fixed a file descriptor leak; made |
| sure all functions call log entry/exit functions.) |
| |
| Badblocks now flushes its output file as bad blocks are discovered. |
| |
| The uuid library is now more paranoid about assuming the correctness |
| of the /dev/random device; it mixes in a stream of bytes from |
| random/srandom, just in case. |
| |
| Update Debian files to reflect the fact that I am now the Debian |
| maintainer of e2fsprogs. Other various Debian-specific packaging |
| cleanups. |
| |
| Move the source tarball generation functions from the top-level |
| makefile to the util/gen-tarball script. |
| |
| Updated the Turkish .po translation file. |
| |
| Added Heimdal and MIT krb5 extensions to the com_err library to make |
| it more compatible with com_err libraries from those distributions. |
| |
| Changed dumpe2fs to always display the superblock fields relating to |
| the journalling and/or directory indexing feature even if those |
| features are not enabled. |
| |
| Updated and clarify copyright statement vis-a-vis alpha releases of |
| e2fsprogs. |
| |
| The ss library will now try to dynamically link to the readline |
| library and use it if it is present in the system. This means that |
| the debugfs program now has line editing and history features. The |
| SS_READLINE_PATH environment variable is used to find a readline or |
| readline-compatible library. |
| |
| E2fsck now finds most duplicate filenames (all when rebuilding all |
| directories via the -D option) and offers to delete or rename |
| duplicate filenames/directory entries. (Addresses Debian Bug #176814). |
| |
| Fix bug in e2image. When writing out a raw image file, include data |
| blocks from symlinks that do not store the symlink within the inode. |
| |
| Fix bug in resize2fs which incorrectly moved the block and inode |
| bitmaps for sparse superblock filesystems and incorrectly marked |
| blocks as in use. (Addresses Debian bug #174766) |
| |
| Added a new shared library, the blkid library, which efficiently |
| allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL |
| and UUID filesystem specifiers without needing to search all of the |
| devices in the system. Instead, the device is looked up in a cache |
| file, and then verified to make sure the blkid cache is correct. |
| |
| Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for |
| the device name, using the blkid library. (Addresses Debian bugs |
| #166048, #179671) |
| |
| Fsck now supports backslash escapes in /etc/fstab so that \040 can be |
| used for spaces in device labels. |
| |
| Removed 32-bit limitations for debugfs's dump command. |
| |
| If the user specifies a large number of inodes, Mke2fs will |
| automatically adjust the number of blocks per group to find a valid |
| set of filesystem parameters. |
| |
| Add workaround to detect broken MD devices where when some of the |
| underlying devices are marked read-only, writes to the MD device are |
| silently dropped. E2fsck will detect if there is an attempt to run |
| the journal twice, and abort with an error if this is the case. |
| (Addresses IBM Bugzilla bug #1226) |
| |
| E2fsck will print an error if more than one of the -p/-a, -n or -y |
| options are specified. |
| |
| E2fsck will fix HTREE corruptions in preen mode, without stopping the |
| boot process. This is needed because the 2.4 ext2 filesystem |
| accidentally had the INDEX_FL backwards compatibility code removed. |
| |
| Mke2fs no longer creates filesystems with the dir_index flag set by |
| default; the user has to specifically request it. |
| |
| Update and clarified various man pages. (Addresses Debian bugs |
| #173612, #175233, #175113, and #170497, #185945, #188318) |
| |
| Created man page for the mk_cmds program (from the libss library). |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fix various gcc -Wall nits. |
| |
| Fixed a lot of portability problems that caused e2fsprogs not to build |
| successfully under Solaris and Apple/Darwin. |
| |
| Fixed a Makefile dependency to allow building e2fsprogs using parallel |
| make jobs. |
| |
| Changes to create a subset distribution which consists only of the |
| et, ss, uuid, and blkid libraries. The configure script and top-level |
| makefile were changed to support working with a subset distribution. |
| |
| Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not |
| actually used, and might people who are looking for |
| EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use. |
| |
| Updated debian files to fix a number of Lintian warnings. |
| |
| Updated config.guess and config.sub with newer versions from the FSF. |
| |
| Removed unnecessary libraries from being linked into the fsck, lsattr, |
| chattr, and blkid executables. |
| |
| E2fsprogs 1.32 (Nomvember 9, 2002) |
| ================================== |
| |
| Fixed a bug in the Unix I/O routines which caused needless writebacks |
| of clean blocks from the unix_io cache (they were erroneously marked |
| as being dirty, so they were getting written back to disk before |
| getting evicted from the disk cache). This was harmless, but it |
| significantly slowed down e2fsck. |
| |
| Made some other minor optimizations to the Unix I/O routines to save a |
| small amount of CPU time. |
| |
| Updated internationalization files. |
| |
| |
| E2fsprogs 1.31 (Nomvember 8, 2002) |
| ================================== |
| |
| Update EVMS ext2fsim plugin with EVMS 1.2. (We still support |
| compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error |
| handling for child process that die unexpectly. Add a hack to force |
| mkfs to create filesystems that won't cause problems with hardware |
| that has 2k or 4k minimum blocksize requirements. Read from child |
| processes in non-blocking mode, so that the GUI continues to update. |
| |
| Fix e2fsck so that it returns the appropriate exit code when the root |
| filesystem has been changed, so that system's rc scripts will be told that |
| the system needs to be rebooted. |
| |
| Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag |
| was set, some of the descriptor blocks that should have been written |
| out were getting skipped. |
| |
| Changed e2fsck to force out changes to the backup copies of the |
| superblock and block group descriptors when important changes are made |
| to those data structures. |
| |
| Fix a bug where e2fsck could erroneously mark a filesystem as being |
| clean if a check of dirty filesystem is interrupted with a ^C. (Bug |
| introduced in e2fsprogs 1.28.) |
| |
| If journal debuging is enabled using --enable-jbd-debug, the debugging |
| level is now set via the E2FSCK_JBD_DEBUG environment variable. |
| |
| If byteswapping support is disabled using configure --disable-swapfs, |
| skip the tests which depend on byte-swapping, so that "make check" |
| won't bomb out. |
| |
| Lshattr will now display the indexed directory flag. Also, some of |
| the more esoteric compression flags are supressed unless compression |
| support has been enabled. |
| |
| Update man pages. |
| |
| |
| E2fsprogs 1.30 (October 31, 2002) |
| ================================= |
| |
| When resizing a filesystem, and inodes need to moved, resize2fs will |
| update the inode's ctime field, and the mtime field of the containing |
| directories, so that incremental backups using dump/restore will work |
| correctly. |
| |
| In order to avoid spurious errors, e2fsck wil check the last |
| superblock write time to determine whether or not it can safely use |
| the LOW_DTIME checks to determine if there are inodes on the orphan |
| inode linked list that had somehow gotten disconnected. (Addresses |
| Sourceforge bug #620980) |
| |
| Partition in /proc/partitions that being with the string "lvm" are |
| considered real partitions even if they do not end with a number. |
| |
| Fixed a bug in the the uuid generation function, where if /dev/urandom |
| is not present, but /dev/random is, and there isn't sufficient |
| entropy, the get_random_byte function could spin a loop forever. |
| |
| E2fsck, mke2fs, etc. will now reliably notice when image files are |
| mounted using the loopback interface. (Addresses Sourceforge bug |
| #619119) |
| |
| When flushing buffers (as is done by badblocks, for example) check to |
| see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the |
| FDFLUSH ioctl which causes the MD device driver which causes confusing |
| syslog messages about obselete ioctl messages. (Addresses Sourceforge |
| bug #545832). |
| |
| Debugfs's write command now checks to see if the destination filename |
| exists before creating it. (Addresses Sourceforge bug #478195.) |
| |
| When installing man pages, search for compressed man pages using all |
| commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.) |
| |
| Fixed a bug in fsck where multiple filesystems specified on the |
| command were not being checked in parallel due to a logic bug |
| introduced to support the FSCK_MAX_INST environment variable. |
| |
| We have added a new superblock field, s_mkfs_time, which indicates |
| when a filesystem was created. It is set via mke2fs, and printed out |
| by dumpe2fs, but is not actually touched by the kernel. |
| |
| Dumpe2fs has been made more robust by not aborting if there is an |
| error reading the block/inode bitmaps; instead it will still print out |
| the location of the block/inode bitmaps and inode table. |
| |
| Add support for the an alternative block group descriptor layout which |
| allows for on-line resizing without needing to prepare the filesystem |
| in advance. (This is the incomat feature flag meta_bg.) |
| |
| Add support for storing default mount options in the superblock, so |
| that the filesystem can be mounted with specific mount options without |
| needing to specify them on the mount command line or in the /etc/fstab |
| file. |
| |
| Add support for a new inode flag, which is to be used for indicating |
| the top of directory hierarchies for the Orlov block allocator. |
| |
| Fix e2fsck so that if it creates the lost+found directory, it does so |
| with the more apporpriate permissions of 0700. Also change |
| mklost+found so that it also creates the directory 0700. |
| |
| Fixed format bug in e2fsck if NLS is in use. |
| |
| Add a German translation for e2fsprogs's NLS support. |
| |
| Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at |
| the beginning of the inode table. This won't matter much, since if |
| there is a bad block at the beginning of the inode table, the root |
| directory won't be available. But at least e2fsck won't crash in this |
| case. |
| |
| Fixed endian problems in the htree code for e2fsck and debugfs. |
| |
| When byte-swapping a filesystem on a PPC architecture, byte-swap the |
| bitmaps since the historical big-endian ext2 variant had byte-swapped |
| bitmaps, and the ext2fs library assumes this. This fixes the |
| regression test suite on PPC machines. |
| |
| Fix e2image so that it handles a bad block in the inode table |
| appropriately. |
| |
| E2fsck now uses a more sophisticated algorithm to salvage corrupted |
| directories that recovers more information in the corrupted directory |
| block. |
| |
| E2fsck now performs additional consistency checks on indexed (HTREE) |
| directories. |
| |
| Fix bug where efsck might get confused about whether a completely |
| empty directory block is an empty leaf block or an interior htree |
| node. This could cause e2fsck to get confused into think that a valid |
| indexed directory was corrupted. |
| |
| E2fsck no longer creates an empty directory entry at the end of a |
| directory block when optimizing a directory. This would cause some |
| earlier versions of the dxdir kernel code to corrupt the directory |
| when attempting to split a node containing an empty directory entry. |
| |
| E2fsck could sometimes in rare circumstances leave the indexed flag |
| set after a small directory was optimized by compressing it instead of |
| indexing it. (This should never happen in real life, since |
| directories that small wouldn't have been indexed, but better safe |
| than sorry.) |
| |
| E2fsck now only updates the master superblock in all cases. This |
| slightly shortens its run time. |
| |
| Ext2ed can deal with directory entries of length 0; previously it |
| would get stuck in an infinite loop. |
| |
| Fsck now has support for reiserfs volumes when parsing LABEL= and UUID= |
| specifiers. (Sourceforge patch #613447) |
| |
| Badblocks will now work correctly on read-only devices such as |
| CD-ROM's. (Sourceforge patch #600451) |
| |
| Updated and clarified man pages. (Addresses Debian bug #167108) |
| |
| |
| E2fsprogs 1.29 (September 24, 2002) |
| =================================== |
| |
| Fixed a bug in e2fsck which could corrupt a directory when optimizing |
| it (via the -D option) or rebuiliding the hash tree index with a 1 in |
| 512 probability, due to a fence post error. |
| |
| Fixed a bug in the LVM support code which caused LABEL='xxx' not to |
| work correctly. |
| |
| Mke2fs now enables the directory indexing flag by default. (Since |
| this is a compatible feature flag, it's safe to do so.) |
| |
| Tune2fs will support setting the directory indexing feature flag. It |
| will automatically set up the default hash algorithm and hash seed |
| fields in the superblock. |
| |
| If the bone-headed user enters the root filesystem twice in |
| /etc/fstab, the -R option which skips the root filesystem will skip |
| all of them. (Addresses Debian bug #159423). Note! This is not a |
| precedent for dealing intelligently with any other kind of doubled |
| entry in /etc/fstab! |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| Removed perror declaration in lib/et/internal.h. All modern systems |
| can be expected to define perror() these days. Besides, the lib/et |
| code wasn't using perror at all anyway. :-) |
| |
| |
| E2fsprogs 1.28 (August 31, 2002) |
| ================================ |
| |
| Add support for the Hashed-Tree Directory Indexing to e2fsck. Support |
| for setting the htree flag is not included yet, although it can be |
| manually turned on via the debugfs program. |
| |
| Clarified e2fsck error message which is printed when it cannot find |
| sufficient contiguous block when relcating filesystem metadata. |
| |
| Added support for building an EVMS plugin module for ext2/3. This |
| module is substantially the same as the EVMS module shipping with EVMS |
| 1.1, with one or two bugfixes. E2fsprogs can also build this plugin |
| for use with EVMS 1.0 (which did not include the ext2 plugin module), |
| if the configure --enable-old-evms flag is given. |
| |
| Fsck will search through EVMS volumes when trying to resolve |
| filesystem specifications such as LABEL=xxx or UUID=xxx. |
| |
| Added a new utility program, /sbin/findfs, which will return |
| filesystem specifications such as LABEL=xxx or UUID=xxx, and prints |
| the device name. |
| |
| Update and clarified various man pages. (addresses Debian Bug #145044, |
| #146437, #131350, #151990, #144621, #141938) |
| |
| If there are no filesystems specified on fsck's command line, fsck now |
| treat that as if the -As options were given. Previously it would |
| simply do nothing. (Addresses Debian Bug #153102) |
| |
| Mke2fs no longer treats a failure to be able to clear the MD signature |
| at the end of the filesystem as a fatal error. (Addresses Debian Bug |
| #155007) |
| |
| The e2p library functions (which are used by lsattr and chattr) now |
| double check to make sure the file is a regular file or directory |
| before attempting to use the ext2 ioctls. Some device drivers |
| unfortunately respond to the ext2 ioctl's with unknown behaviour. |
| (Addresses Debian Bug #152029). |
| |
| The extended attribute handling has been updated to correspond with |
| the latest V2 bestbits ACL code. |
| |
| Fixed bug in e2fsck which caused it to not clear the dtime field when |
| processing truncated inodes on the orphan list. This could cause data |
| loss(!) if a filesystem is rebooted before a truncate has been |
| committed. |
| |
| E2fsck now uses red/black trees in pass1b, which removes some O(n**2) |
| algorithms. This makes e2fsck much faster in the case of severely |
| corrupted filesystems where a large number of blocks are claimed by a |
| large number of inodes. (Thanks to the 2.5 IDE device driver for |
| inspiring this work.) |
| |
| Resize2fs has been significantly sped up when shrinking and expanding |
| a filesystem by a very small number of blocks (for example, when EVMS |
| is converting a partition to be an EVMS legacy volume). |
| |
| Added a new option to e2fsck, -D, which will optimize or compress all |
| of the directories in the filesystem. |
| |
| E2fsck now catches SIGINT and SIGTERM to make sure it will can |
| properly clean up and only exit at safe points. Fsck will pass |
| SIGINT/SIGTERM to its child processes, and wait until they have all |
| exited before it exits. |
| |
| The uuid parsing code in the uuid library now properly complains when |
| an illegally formated uuid is presented to it. (Addresses Debian bug |
| #152891) |
| |
| Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10 |
| and 2.4.17, since the workaround can cause problems when using a 2.4 |
| kernel with an old version of glibc built with the 2.2 headers. |
| |
| Fixed a bug in mke2fs where it wasn't properly clearing the initial |
| superblock used by other filesystems. (Addresses Debian bug #147256.) |
| |
| Added support for the synchronous directory feature written by Andrew |
| Morton. |
| |
| The debugfs program can delete directories using the rmdir command. |
| |
| Add support for 8k and 16k filesystems (for systems with page sizes |
| that are greater or equal to 8k or 16k, respectively). Note that |
| these filesystems can not be mounted on x86 systems, or other systems |
| with only 4k page sizes, due to limitations in the current Linux VM |
| code. |
| |
| Resize2fs requires that the filesystem state be valid and have no |
| errors; otherwise, e2fsck -f must be run first. (Previously it simply |
| required that the last fsck time be greater than the last mount time.) |
| |
| Configure now defaults the man pages directory to /usr/share/man on |
| Linux systems. |
| |
| E2fsck now offers to truncate inodes which contain too many blocks (so |
| that i_blocks would overflow. Also fixed handling of large sparse |
| files. |
| |
| E2fsck now more completely checks for symlink validity, including |
| requiring NULL termination and length checks. |
| |
| E2fsck will offer to try forcing a disk write to remap a bad block |
| after finding a read error when reading a filesystem metadata block. |
| |
| Fixed a bug in debugfs which caused the -b and -s options to crash |
| debugfs, as well as breaking the testb, setb, and clearb functions. |
| |
| Added a bmap command to debugfs which calculates the logical to |
| physical block mapping for a particular inode. |
| |
| Fixed a bug in code which checked to see if a device was mounted which |
| sometimes (rarely) failed in the case of a plain file. |
| |
| Fixed a bug in resize2fs where when it reported an error, it would |
| print a message erroneously indicating that the filesystem had been |
| resized before it aborted. |
| |
| When resizing a plain file which is smaller than the requested size, |
| resize2fs will attempt to extended the file so that programs like |
| e2fsck will not complain that the file is too small. |
| |
| Resize2fs will print the actual new size of the filesystem when it is |
| finished resizing. |
| |
| Fixed a bug in debugfs where "ls -l" would report incorrectl file type |
| information on big-endian systems. |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fixed collisions with C++ reserved words. |
| |
| Added portability fixes for building e2fsprogs on the HURD and AIX. |
| |
| Added the ext2ed program for creation of test cases. (ext2ed has many |
| limitations and bugs which make it unsuitable for production use.) |
| |
| The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new |
| flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the |
| name_len field is byte swampped on big-endian machines, since in the |
| V2 structure, name_len is a char field which is doesn't need to be |
| byte swapped --- except if an old-style kernel had byte-swapped the |
| name_len field as part of the V1 structure. |
| |
| |
| E2fsprogs 1.27 (March 8, 2002) |
| ============================== |
| |
| The warning messages for mke2fs now go to standard error. |
| |
| Fixed to make sure "make check" runs all of the test programs with |
| LD_LIBRARY_PATH set, so that we test the libraries in the build tree. |
| |
| The mke2fs program checks the boot sector for the BSD disk label, and |
| avoids erasing it if it is there. |
| |
| Fixed a bug in e2fsck which caused it to core dump if the journal |
| inode was missing when it was supposed to be there. |
| |
| E2fsck now prints ranges in pass 5 when printing deltas for the block |
| and inode bitmaps. |
| |
| Debugfs's "ls -l" command now will print out the file type information |
| in the directory entry. |
| |
| Create man pages and hard links for fsck.ext3 and mkfs.ext3. If |
| mke2fs is invoked as mkfs.ext3, create the filesystem with a journal. |
| |
| Debugfs can now examine the experimental directory indexing |
| information. |
| |
| Fixed bug in debugfs which caused it to core dump if modify_inode is |
| called without an open filesystem. |
| |
| The debugfs lsdel command now runs its output through a pager first. |
| |
| When installing manual pages, remove the compressed manual pages first. |
| |
| Synchronized with Debian's packaging information for e2fsprogs-1.26-1. |
| |
| Fix the 2.4 resource limitation workaround introduced in 1.26 which |
| actually broke things on mips32, sparc32, and Alpha platforms. |
| |
| Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made |
| (which is required by the newer libintl libraries). |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fixed various gcc -Wall complaints. |
| |
| Fixed a few memory leaks in the e2fsck journaling code, and in the |
| ismounted code checking for a swap device. |
| |
| Add new inode I/O abstraction interface which exports an inode as |
| an I/O object. |
| |
| Exported ext2_file_flush as a public interface. |
| |
| In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer. |
| |
| Lots of small random portability fixes to make e2fsprogs build under |
| AIX --- even without the 5L compatibility toolkit, and even using the |
| uber-crippled AIX native C compiler. |
| |
| |
| E2fsprogs 1.26 (February 3, 2002) |
| ================================= |
| |
| Dumpe2fs will keep going now if the bad block inode can't be read. |
| (Previously it stopped with a fatal error.) |
| |
| E2fsck will now give an opportunity to run the journal even if the |
| recovery flag is not set. This is the default behaviour if e2fsck is |
| using a backup superblock, since the needs_recovery flag will never be |
| set in the backup superblock copies. |
| |
| E2fsck now automatically finds the backup superblock/group descriptors |
| even when the primary superblock is completely destroyed for 2k and 4k |
| filesystems. (Previously it just guessed/assumed that we were dealing |
| with a 1k filesystem in that case, and users had to manually specify |
| the backup superblock number.) |
| |
| Fixed a bug in e2fsck where it dereferences a null pointer when there |
| is a problem opening a filesystem in preen mode. |
| |
| E2fsck now handles external journals correctly; previously it trashed |
| the external journal device if the journal needed to be replayed. |
| |
| Work around ulimit incompatibility problem caused by recent 2.4 |
| kernels; the unix IO module will automatically try to set any resource |
| limits to be infinite on startup. |
| |
| Fixed a bug in e2fsck where it wasn't allocating a new block or inode |
| bitmap if it wasn't present and the blocksize was 2k or 4k. |
| (Addresses Debian Bug #116975) |
| |
| E2fsck will check and fix botched ext3 V1 to V2 superblock updates by |
| clearing the new V2 fields if they do not make sense or if the ext3 |
| superblock is version 1 superblock. |
| |
| E2fsck will automatically relocate the ext3 journal from a visible |
| file (i.e., /.journal) to an hidden inode if the filesystem has been |
| opened read/write. This allows the users to add a journal while the |
| filesystem is mounted, but the next time the system is rebooted, the |
| journal file will disappear. This avoids problems with backups, |
| stupid operators with superuser bits, etc. |
| |
| Fix a bug in fsck where it would not support a filesystem type of |
| "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx. |
| |
| Fsck now supports fstab entries of the form "ext3,ext2". It will also |
| automatically identify reiserfs filesystems. |
| |
| The number of processes spawned by fsck can now be limited using the |
| FSCK_MAX_INST environment variable. |
| |
| Fsck now searchs the LVM proc hierarchy to find logical volumes which |
| should be searched for UUID and label information. |
| |
| Work around a bug in 2.4.10+ kernels by trying to unset the filesize |
| limit if at all possible, when opening a block device. (The filesize |
| limit shouldn't be applied against writes to a block device.) |
| |
| In mke2fs and e2fsck, specifying the -c option twice will now do |
| a read/write test on the disk. Update the man pages to encourage |
| using the -c option, and to discouraging running badblocks separately, |
| since users tend to forget to set the blocksize when running |
| badblocks. |
| |
| Mke2fs now automatically clears the immutable attribute on a |
| pre-existing .journal file left over from a previous failed attempt to |
| add a journal to an alreadyy-mounted filesystem. |
| |
| Fixed mke2fs's exit codes to consistently indicate when the mke2fs |
| operation failed. |
| |
| Mke2fs now creates the lost+found directory with permissions of 0700, |
| so that files that had previously lived in protected directory are |
| safe if they get dropped in lost+found and the system administrator |
| doesn't deal with immediately. (Addresses Debian #bug 118443) |
| |
| Mke2fs and e2fsck (and all programs that use the |
| ext2fs_check_if_mounted function) will now properly identify that a |
| device is mounted, even in cases where devfs has confused things with |
| multiple devices names with the same identity, or if a dim-witted |
| system administrator has done something stupid like creating device |
| file aliases in their home directory. Also now checks for swap devices |
| by using /proc/swaps. (Addresses Debian bug #106622) |
| |
| Added a new option (-T) to tune2fs which sets the time a filesystem |
| was last checked. |
| |
| Speed up e2image when creating sparse raw image files by optimizing |
| away excess lseek() system calls. |
| |
| Fix support of large (> 2GB) files when used as a filesystem in |
| mke2fs, tune2fs, debugfs, and findsuper. |
| |
| Debugfs's stat and icheck commands now properly deals with large (> |
| 2GB) files. |
| |
| Debugfs's set_super_value command now prints out the list of valid |
| superblock fields which can be set using the command. |
| |
| Debugfs's rm and kill_file command now updates the superblock free block |
| and inode counts, thus keeping the filesystem consistent. |
| |
| Debugfs's lsdel command now takes an optional argument which allows |
| the user to only see the most recently deleted files. |
| |
| A new command (undel) was added to debugfs which automates |
| undeleting a deleted inode and linking it back to a directory. |
| |
| Debugfs's ls command now takes a new option, -d, which lists |
| deleted directory entries. |
| |
| Debugfs's testb, freeb, setb, and find_free_block commands now take an |
| optional count argument. |
| |
| Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will |
| be used to signal that a particular inode should not be eligible for |
| tail-merging --- this is needed for programs like LILO. |
| |
| The findsuper (an unreleased, uninstalled utility program) has been |
| improved to add extra validity checks and to add a progress meter. |
| (It is still an unsupported program; the officially supported way to |
| recover from a trashed partition table is to use gpart; findsuper is |
| for wizards only. :-) |
| |
| Debugfs was fixed to compile with "configure --disable-swapfs". |
| |
| Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) |
| |
| Added new translation file for Turkish. |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fix general gcc -Wall complaints. |
| |
| E2fsprogs (mostly) works with the dietlibc. |
| |
| The programming texinfo file has been expanded to include description |
| of additional libext2fs functions. (Still not compeltely done, but a |
| lot of the more important functions have been documented.) |
| |
| Added a umask structure to struct_ext2_filsys, which currently only |
| modifies the behaviour of ext2fs_mkdir(), but if we add any file |
| creation functions to libext2fs, we should also make sure they respect |
| the umask setting. |
| |
| The build-rpm script was fixed to be a bit more safe. |
| |
| The tests' Makefile now has a way of automating test case creation |
| for e2fsck, using "make testnew". |
| |
| Created a new function, ext2fs_dir_iterate2 which passes more |
| information to the callback function (identical to the one used by |
| ext2fs_dblist_dir_iterate). The directory iterator functions take a |
| new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted |
| directory entries. If the directory entry is deleted, the callback |
| function will be called with the entry paraemter set to |
| DIRENT_DELETED_FILE. |
| |
| Added new functions, ext2fs_inode_alloc_stats and |
| ext2fs_block_alloc_stats, which takes updates block/inode allocation |
| statistics in the bitmaps, block group descriptors, and superblock |
| when inodes or blocks are allocated or deallocated. |
| |
| |
| E2fsprogs 1.25 (September 20, 2001) |
| =================================== |
| |
| This is primarily a bug-fix release; no new features were added, but |
| there are a number of embarassing bug fixes and cleanups applied. |
| |
| Fix a bug mke2fs which causes stack garbage to be written to disk when |
| zapping disk sectors. (This bug could cause mke2fs to core dump for |
| some kernels, I suspect with security enhancement patches.) |
| |
| Remove unneeded #include of <linux/config.h> which was breaking |
| building e2fsprogs on the Hurd. (Addresses Debian bug #112414.) |
| |
| Updated tune2fs man page to reflect the fact that adding or removing a |
| journal doesn't require running e2fsck. |
| |
| Remove use of AC_REQUIRE from autoconf which had been used to prevent |
| AC_CANONICAL_HOST from being called twice; unfortunately this causes |
| recent autoconf to bomb out since they don't allow AC_REQUIRE to be |
| used outside of autoconf macros. Fortunately, it doesn't seem to be |
| necessary any more, anyway. |
| |
| E2fsck will now not fall back to an alternate superblock if the user |
| specifies the superblock location explicitly on the command-line. |
| This allows easier recovery from a situation where the primary |
| superblock and block groups are slightly corrupted, but the backup |
| superblocks are completely broken. |
| |
| Fix problem which caused compile_et and mk_cmds to blow up if |
| e2fsprogs was in a directory with a pathname that contained spaces. |
| |
| We are now more paranoid about checking the entry in /etc/mtab to make |
| sure the filesystem is really mounted, since some broken distributions |
| (read: Slackware) don't initialize /etc/mtab before checking non-root |
| filesystems. (Slackware also doesn't check the root filesystem |
| separately, and reboot if the root filesystem had changes applied to |
| it, which is dangerous and broken, but there's nothing I can do about |
| that.) |
| |
| Make UUID library C++ friendly by adding appropriate extern "C" |
| declarations and using const in the function declarations. |
| |
| Fix up the com_err texinfo file so that it can product a valid info |
| file (previously, it could only be used to generate paper |
| documentation using texinfo.tex). |
| |
| |
| E2fsprogs 1.24a (September 2, 2001) |
| =================================== |
| |
| Fix brown-paper bug in mke2fs which caused it to segfault when |
| printing the version string. |
| |
| |
| E2fsprogs 1.24 (August 30, 2001) |
| ================================ |
| |
| Revert the BLKGETSIZE64 support, since for some distributions, this |
| ioctl has been used by an unofficial kernel patch to update the last |
| sector on the disk, and this was causing disk corruption problems as a |
| result. |
| |
| Mke2fs is now more careful about zapping swap space signatures and |
| other filesystem/raid superblock magic values so that programs like |
| mount who try to use hueristics to determine the filesystem type of a |
| partition are less likely to be confused. |
| |
| E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a |
| regular file (since Andreas Dilger's on-line resizing tools will set |
| its mode bits). |
| |
| Fixed some minor texinfo, man pages nits for spelling errors, |
| texinfo warnings, etc. (Addresses Debian bug #110621.) |
| |
| E2fsprogs program no longer print the filesystem version number |
| (i.e. 0.5b), since it only confuses people and doesn't serve any real |
| purpose. |
| |
| E2fsck will once again compile under libc5, since it will supply its |
| own version of strnlen if necesssary. |
| |
| mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers |
| when specifying the external journal device. tune2fs will also search |
| devices looking for the externla journal debice when removing. |
| |
| E2fsprogs 1.23 (August 15, 2001) |
| ================================ |
| |
| Add initial support for extended attributes (EA); e2fsck will |
| correctly handle a filesystem with EA's and check the EA blocks for |
| corruptions. |
| |
| E2fsck's symlink sanity checking has been cleaned up. It now checks |
| the i_size value of fast symlinks, and checks for immutable flags |
| being set of symlinks, etc. |
| |
| E2fsck now offers to clear inodes which are special files that have a |
| non-zero i_blocks or i_size field. (The i_size field check was in the |
| previous version of the code, but due to a bug it didn't offer to |
| clear the inode unless i_size and i_size_high were both non-zero.) |
| |
| E2image can now create "raw" image files, which only contain the |
| filesystem metadata placed in a spare file so that e2fsck, dumpe2fs, |
| debugfs, etc., can be run directly on the raw image file. |
| |
| Add support for the 64-bit block device patches. |
| |
| Fixed bugs in creating external journals with a 1k blocksize. |
| |
| Add initial support for external journals (so long as the external |
| journal only supports a single filesystem) in e2fsck. |
| |
| Remove requirement for needing to run fsck on a filesystem after |
| removing a journal (either internal or external). |
| |
| The man pages now document how to create and manage external journals. |
| |
| Speed up the check of an ext3 filesystems by avoiding a needless flush |
| of all of the superblock and block group descriptors. |
| |
| Speed up creating an internal journal using tune2fs in the case where |
| the filesystem has a lot blocks already allocated. |
| |
| Tune2fs has been fixed to make sure that only error messages go to |
| stderr, and normal message go to stdout. (Addresses Debian bug #108555) |
| |
| Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will |
| now not set the sparse_super feature. (Addresses Debian bug #108165) |
| |
| Add support in fsck for the filesystem type "auto". |
| |
| Fsck -A will not try to interpret device names for filesystems which |
| have a pass number is 0. (Addresses Debian bug #106696). |
| |
| Fsck prints a warning message if now valid filesystems are passed to |
| it. (Addresses Debian Bug #107458.) |
| |
| E2fsck now gives an explicit warning if there filesystem still has |
| errors at the end of the run. (Addresses Debian bug #104502) |
| |
| E2fsck will set the EXT2_ERROR_FS flag if the journal superblock |
| reflects an error. E2fsck will also not run the orphan list if the |
| filesystem contains errors, since the orphan list might be corrupted. |
| |
| E2fsck now prints the number of large files when given the -v option. |
| |
| Fixed minor memory leaks in e2fsck. |
| |
| Some minor man pages updates. (Addresses Debian bug #30833, #108174) |
| |
| |
| E2fsprogs 1.22 (June 22, 2001) |
| ============================== |
| |
| Fixed a bug in e2fsck's handling of orphan inodes which are special |
| files (i.e., block/character device files, named FIFO's, etc.). |
| |
| Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused |
| tune2fs to fail at adding a journal to a mounted filesystem. |
| |
| Fixed a few big-endian bugs in e2fsprogs |
| * The directory block functions were accidentally reporting |
| some directories as corrupted when they weren't. |
| * If e2fsprogs is compiled --disable-swapfs, the C language |
| equivalents weren't being included for big-endian platforms. |
| (Fixes Debian bug #101686). |
| |
| Fixed a Hurd compilation problem. (Addresses Debian bug #101361) |
| |
| Programmer's notes: |
| ------------------- |
| |
| Use platform independent method of defining the BLKFLSBUF and FDFLUSH |
| ioctls, and allow them to be defined for non-i386 platforms. |
| |
| The uuid.h header file is now protected against multiple inclusions. |
| |
| E2fsprogs is now being developed using BitKeeper. Changed the test |
| scripts to deal with BK's stripping CR characgters from text files, |
| and changed the top-level Makefile.in to avoid including BitKeeper |
| files when generating the source tarball. |
| |
| |
| E2fsprogs 1.21 (June 15, 2001) |
| ============================== |
| |
| Added new configure flags which allow a subset e2fsprogs to be built; |
| this is most useful for boot floopies, since the resulting shared |
| libraries and programs are slimmed down by removing features that |
| aren't necessary for a boot floppy. The new flags that were added |
| are: --disable-swapfs, which removes support for byte swapping old |
| legacy PPC/68k filesystems, --disable-debugfs, which removes support |
| for debugfs from the libext2fs library, --disable-imager, which |
| removes support for the e2image program, and --disable-resizer, which |
| removes support for resize2fs. |
| |
| E2fsck now prints the number of mounts or days elapsed since the last |
| check when e2fsck is forced to check an otherwise clean filesystem. |
| |
| Tune2fs now prints an informative message about how often a filesystem |
| will be checked when adding a journal to the filesystem, to remind the |
| user that he/she may want to adjust those parameters using tune2fs |
| -c/-i. |
| |
| Worked around hurd brain-damage which causes e2fsck to sometimes |
| believe a filesystem is the root filesystem based on device numbers |
| (since Hurd doesn't have dev_t's, which is arguably a POSIX.1 |
| violation). |
| |
| Fixed a bug introduced in 1.20 which caused e2fsck to abort with an |
| erroneous error with the -F option was specified. |
| |
| Fixed a ext3 recovery bug in the revoke handling; synchronized with |
| ext3 0.7a. |
| |
| Fixed two bugs in e2fsck's handling of dup block handling, dealing |
| with relatively uncommon edge cases: a directory with an indirect |
| block which is claimed by another file, and when the last inode in the |
| filesystem has blocks claimed by another file. |
| |
| E2fsck now checks to see if the i_size field of a fast symlink is too |
| big, and offers to clear the symlink if so. |
| |
| E2fsck now checks to see if i_size_high of special files is non-zero, |
| and offers to clear i_size_high. |
| |
| Fix e2fsck's handling of incompatible journal flags so that the user |
| has chance to abort, and then has the option to clear out the journal |
| entirely. (Addresses Debian bug #98527.) |
| |
| Fixed a bug in fsck which could cause it to core dump if a mix of |
| standard and non-standard device names are used in /etc/fstab. |
| (Debian bug #100559) |
| |
| Fixed a bug in debugfs which caused read errors when copying a file to |
| not be noticed. |
| |
| The debugfs set_super_value command can now modify the s_lastcheck field. |
| |
| Fixed a bug in lsattr and chattr which was accidentally introduced in |
| 1.20 to support > 2GB files; both lsattr and chattr wasn't reading |
| directories correctly because the change modified the layout of struct |
| dirent to be incompatible with the libe2p shared library. |
| |
| Cleaned up the mke2fs manual page and included a discussion about why |
| it's good to periodically check the filesystem even when journaling is |
| enabled. |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fix general gcc -Wall complaints. |
| |
| The types needed by the ext2 header files are now provided by |
| lib/ext2fs/ext2_types.h, instead of include/asm/types.h. |
| |
| Integers are now preferred to longs when trying to find a 32-bit type |
| in ext2_types.h. Also, if linux/types.h has already been defined, |
| don't try to redefine the types. |
| |
| Fixed make depend script so that it automatically corrects the |
| pathname cleanups performed by make -M, so I don't have to fix them up |
| by hand. |
| |
| Fixed the d_loaddump test case to be more robust, and not depend on |
| bash'isms. |
| |
| Removed debugfs's dependence on pread(), which was accidentally |
| intrudced in e2fsprogs 1.20 |
| |
| Fixed a performance bug in the libext2fs's icount routine; the size |
| estimate of the icount array was incorrectly being calculated. |
| |
| Removed use of the badblocks compatibility functions in the e2fsprogs |
| programs. |
| |
| Added paranoia code which protects against strange cases where /etc |
| isn't on the root filesystem, or if /etc/mtab doesn't exist. |
| |
| The header file ext2_types.h is now installed. |
| |
| Autoconf is used to determine when we are on big-endian machines, |
| instead of doing run-time tests, to save a few bytes of code. |
| |
| The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap |
| functions are no longer inline functions, which saves space and |
| doesn't really cost any real performance. |
| |
| The ext2fs library no longer depends on the e2p library. (What need |
| there was of it --- namely, fsetflags, was coded in-line). |
| |
| Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even |
| when the user is stupid and tries compiling the package using "make |
| install" as root. |
| |
| Miscellaneous code cleanups: |
| * Added missing files from Makefile.in's SRCS file, so that |
| their dependencies would be properly calculated. |
| * Removed redundant code |
| * Fixed comments in code |
| * Removed no-longer unneeded argsused #pragma. |
| |
| |
| E2fsprogs 1.20 (May 20, 2001) |
| ============================= |
| |
| Add support for replaying the ext3 journal purely in user mode, |
| including handling the orphaned inode list. Used code contributed by |
| Andreas Dilger, with bug fixes and the orphaned inode handling done |
| by Theodore Ts'o. |
| |
| The mke2fs and tune2fs programs can create or modify a filesystem to |
| include an ext3 journal. Tune2fs also can be used to remove an ext3 |
| journal from a filesystem. |
| |
| E2fsck will now check for the existence of a linked list of orphan |
| inodes in the superblock, and clear those inodes before starting the |
| rest of the filesystem check (but after the journal playback). |
| |
| E2fsck now validates the file descriptor passed to the -C option, |
| which saves against the completion bar getting written to an |
| unexpected location, such as the disk being checked. (Debian |
| bug/wishlist #55220) |
| |
| E2fsck will now bump the filesystem revision number from zero to one |
| if any of the compatibility bits are set. |
| |
| Fixed a bug where a badly corrupted directory on a big endian system |
| could cause e2fsck to die with a bus error. The |
| ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in |
| the ext2 library now does alignment sanity checks on the rec_len field |
| of the directory entry before using it. |
| |
| The ext2 library has been enhanced to make tune2fs safe to run on |
| mounted filesystems. (Users could usually get away with using tune2fs |
| on mounted filesystems before, but with the advent of ext3 and |
| journaling, it became important to make tune2fs was *really* safe for |
| use even when the filesystem being modified is mounted.) E2label is |
| now implemented by tune2fs using an argv[0] dispatch, so that e2label |
| is also now safe for use on mounted filesystems. |
| |
| Added a new program, e2image, which creates a backup of critical ext2 |
| filesystem data structures. The generated image file can be examined |
| using dumpe2fs and debugfs. In the future, e2fsck will be able to use |
| the image file to help recover very badly damaged filesystems. |
| |
| Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files |
| no longer cause e2fsck to bomb out. Also treat files > 2GB as being |
| large file when deciding whether or not the filesystem has large files. |
| |
| Fixed lsattr and chattr so that they work correctly on large files. |
| (Fixes Debian bug #72690.) |
| |
| Removed limitation in get_device_size() which imposed a one terrabyte |
| filesystem limitation. (Most 2.2 kernels still have a signed int |
| problem which cause 1 TB block device limitation. Fortunately, the |
| kernel patches to fix this are much easier than fixing the 2TB |
| limitation in the kernel. :-) |
| |
| A max_mount_count of zero is now treated as if no mount count were |
| set. (Previously, no mount count was indicated by using -1, and a |
| mount count of zero caused e2fsck to always be run.) |
| |
| Mke2fs supports two new filesystem types largefile and largefile4. |
| |
| Mke2fs now adds some randomness in s_max_mount_count so that multiple |
| filesystems won't be all checked at the same time under normal |
| operations. |
| |
| Fixed bug in the progress bar printing code which could cause e2fsck |
| to core dump on an illegal filesystem. |
| |
| Fixed bug in fsck which could allow more than one instance of e2fsck |
| to be printing a progress bar. (Debian bug #65267) |
| |
| Fsck using a UUID or a LABEL specifier will work even if devfs is |
| compiled into the kernel and not mounted. If the pathnames in |
| /proc/partitions are incorrect, fsck will search /dev for the correct |
| device (using the new ext2fs_find_block_device library function). |
| Fsck now also checks the RAID devices first so that they are properly |
| found when they are in use. Support has also been added to support |
| additional IDE disks and the DAC 960 device names. (Debian bug #94159) |
| |
| Fixed a bug in fsck which caused it not deal properly with 16 |
| byte long filesystem labels. |
| |
| Fsck's -t option has been made a lot more flexible. The semantics for |
| what happens if a comma-separated list to fsck has been regularized, |
| and it is now possible to filter what filesystems will get checked |
| based what is in the filesystem's fstab entry's option field. (Debian |
| bug #89483.) |
| |
| The dumpe2fs program can now print out the group description |
| information in hex, and also prints the location of the superblock and |
| block group descriptor for those block groups that have them. |
| |
| Mke2fs now clears the ext2 superblock before it starts creating a |
| filesystem, so that the superblock magic number is only written if the |
| filesystem creation process successfully completes. |
| |
| The debugfs program's stat command now pretty-prints the blocks used |
| by an inode so that it's more compact and informative. |
| |
| The debugfs stats command now uses the same libe2p code (which is used |
| by dumpe2fs) to print the superblock header information. This is more |
| complete, and it avoids a bit of code duplication. |
| |
| Added a new debugfs command, set_super_value (ssv) which allows the |
| user to set arbitrary superblock fields. |
| |
| Debugfs was extended to support inode numbers in hex (by prefixing |
| them with 0x), and so that modify_inode can set the inode generation |
| number. Also, there is now a new function command called logdump |
| which will dump an ext3 journal. |
| |
| Fixed a bug in debugfs so that quitting out of the pager doesn't kill |
| debugfs. |
| |
| Debugfs's dump command now stops immediately upon reporting a disk |
| read error. (Fixed a bug in ext2fs_file_read library routine which |
| caused debugfs not to stop.) (Debian bug #79163) |
| |
| On systems with /proc/mounts (mainly Linux systems), /proc/mounts is |
| checked before /etc/mtab is used, since /proc/mounts is more likely to |
| be accurate. |
| |
| Added portability fixes for Solaris and Linux/ia64. |
| |
| Various manual pages were clarified and cleaned up. (Fixed debian |
| bugs #63442, #67446, and #87216) |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| The e2fsck message printer now supports %Iu and %Ig, which will print |
| out the inode's user and group owners, respectively. |
| |
| E2fsprogs now includes its own version of include/linux/ext2_fs.h, so |
| that no longer dependent on the system having the correct version of |
| the kernel header files. |
| |
| Added a new function to libext2, ext2fs_find_block_device(), which |
| searches the system (i.e., /dev, /devfs, /devices) for a pathname to a |
| device given its device number. |
| |
| Added a new function to libext2, ext2fs_sync_device, which centralizes |
| all of the places which might try to use the BLKFLSBUF or FDFLUSH |
| ioctls (and usually failing to define them since the system header |
| files don't usually do this for us, and we're trying to avoid usage of |
| kernel include files now). |
| |
| Added new utility programs in tests/progs: random_exercise and |
| hold_inode. They aren't built by default; they're useful for |
| exercising ext3 filesystem code. |
| |
| Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes |
| the filesystem close functions to only update the superblock, and to |
| not touch the block group descriptors. Needed by tune2fs when |
| modifying a mounted filesystem. |
| |
| Got rid of struct ext2fs_sb and replaced it with the standard struct |
| ext2_super_block from include/linux/ext2_fs.h. Note: this may break |
| source (but not binary) compatibility of some users of the ext2 |
| library. Those applications should just simply do a global search and |
| replace of struct ext2fs_sb with struct ext2_super_block, and include |
| the new header file <ext2fs/ext2_fs.h> which defines it. |
| |
| The ino_t type has been renamed ext2_ino_t to protect applications |
| that attempt to compile -D_FILE_OFFSET_BITS=64, since this |
| inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an |
| unexpected ABI change. |
| |
| The Makefiles have been reworked so that "make check" can be run from |
| the top-level Makefile. |
| |
| Fix general gcc -Wall complaints and removed dead code. |
| |
| Remove use of NOARGS, because we assume everyone does ANSI C these |
| days. |
| |
| Added build-rpm script from sct. |
| |
| New functions ext2fs_image_{inode,super,bitmap}_{read,write} added |
| to support e2image. |
| |
| New function ext2fs_flush_icache which must be called if the |
| application program modifies the inode table blocks without going |
| through ext2fs_write_inode() interface. |
| |
| New ext2fs_check_mount_point() function, which will return the mount |
| point of a device if mounted. |
| |
| The io_channel abstraction now has an optional interface, |
| io_channel_write_range, which allows specific byte ranges to be |
| written. |
| |
| The unix_io IO channel now supports write-through caching, so that |
| journal creation is more efficient. |
| |
| Added x86 assembly language routines to support byte swapping, to |
| reduce executable size. |
| |
| Fixed bug in the utility program subst so that it's possible to |
| replace a substitution variable with a zero-length string. |
| |
| Fixed numbering e2fsck pass1 problem numbers; an extra zero had |
| slipped into some of the problem number. |
| |
| E2fsprogs 1.19 (July 13, 2000) |
| ============================== |
| |
| Release the resize2fs program since the timeout before it could |
| be released under the GPL has finally expired. |
| |
| Add experimental support needed for the ext2 compression patches. |
| This requires compiling e2fsprogs with the --enable-compression flag |
| to the configure script. |
| |
| Added ext3 journalling support. E2fsck will run the journal (if |
| necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is |
| installed as a symlink to e2fsck. Fsck has been taught about ext3, |
| and treats it the same as ext2 in terms of the progress bar logic. |
| Dumpe2fs will display the superblock journaling information if the |
| filesystem has a journal. The ext2 library will now permit opening an |
| ext3 filesystem with the recovery flag set. This is necessary for |
| on-line dump's to work correctly, but there may be issues with this |
| working well since ext3 is much less agressive about syncing blocks to |
| the filesystem, since they're safe on the journal. |
| |
| Tune2fs and e2fsck have been changed to allow the mount_count check to |
| be disabled by setting max_mount_count to -1. (This was already |
| supported by the kernel.) |
| |
| Create a symbolic link for fsck.ext3, since the e2fsprogs utilities |
| are used for ext3 as well. |
| |
| Added internationalization support for e2fsprogs; must be enabled |
| by passing --enable-nls to configure. |
| |
| Always use the provided ext2fs header files to insulate ourselves from |
| kernel version changes. Which include files are used by e2fsprogs |
| have also been cleaned up to improve portability. |
| |
| Limit the number of times that e2fsck updates the progress bar so that |
| people who are booting using a 9600 baud console don't get swampped by |
| too many updates. |
| |
| Improved the loop detection algorithm in e2sck's pass #3 so that it is |
| much, much faster for large filesystems with a large number of |
| directories. |
| |
| The memory footprint for e2fsck is now slightly smaller than before. |
| |
| E2fsck now checks if special devices have a non-zero size, and offers |
| to clear the size field if it finds such an inode. |
| |
| E2fsck now checks if special devices have the append-only flag set, |
| and offers to clear the inode. |
| |
| E2fsck now properly handles some "should never fail" cases during a |
| bitmap copy in pass5. |
| |
| E2fsck now properly prints control characters in filenames as ^A .. ^Z. |
| |
| E2fsck now calculates the correct location of the backup superblock in |
| the case of filesystem blocksizes > 1k. |
| |
| Fixed a bug in e2fsck's calculation of the number of inodes_per_block |
| which normally didn't cause problems under most filesystem parameters, |
| but could cause a valid superblock to be rejected in extreme cases. |
| Other checks for validating superblock values were made more |
| stringent. |
| |
| Added non-destructive write testing to the badblocks program, courtesy |
| of David Beattie. The badblocks also now has an option to input the |
| current set of bad blocks, so that known bad blocks are skipped to |
| speed up the badblocks test. There is also a persistent rescan |
| feature which causes badblocks to run until it has completed some |
| number of passes without discovering any new bad blocks. |
| |
| Badblocks now checks to see if the device is mounted and refuses to do |
| the tests involving writing to the device if it is mounted. Also, |
| badblocks now allows the number of blocks to be checked to be |
| defaulted to the size of the partition. |
| |
| Fixed a bug in fsck which didn't allow non-root users to be able to |
| check filesystems if there were any LABEL= or UUID= entries in |
| /etc/fstab. |
| |
| The Hurd doesn't support the filetype filesystem feature. The mke2fs |
| program now makes sure that for the Hurd, the filestype feature is |
| turned off. E2fsck will check to see if the filetype feature is |
| turned on for Hurd filesystems, and offer to turn off the feature. |
| |
| Mke2fs now has a safety check to make sure the number of blocks do not |
| exceed 32 bits even on a 64 bit platform. |
| |
| Really fixed a bug in fsck to allow "fsck -As" to run interactive |
| fsck's. (For those people who like to do interactive fsck's in the |
| /etc/rc scripts!?!) |
| |
| Debugfs has a few new features: the rdump command, which will do a |
| recursive dump of a directory and all of its contents, and the lcd |
| command which does a local chdir (much like the ftp command of the |
| same name). In addition, the debugfs program and the open_filesystem |
| command now takes three new options: -b and -s, which allows the |
| blocksize and superblock location to be specified, and the -c option |
| which is used in catastrophic situations where the block group |
| descriptors are corrupt. If the -c option is specified, debugfs will |
| skip trying to read in the block and inode bitmaps. |
| |
| Debufs's lsdel command was fixed to handle bad blocks in the inode |
| table. |
| |
| A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use |
| 4 digit years. |
| |
| General improvements in error messages |
| |
| - Mke2fs prints a sane error message if the partition size is zero |
| (usually because the partition table wasn't reread by the |
| kernel due to the partition being busy), instead of "invalid |
| argument passed to ext2 library while initializing superblock". |
| |
| - Fsck now prints more self-explanatory message if an invalid UUID= |
| or LABEL= specification is passed to it. |
| |
| UUID library changed to use the LGPL. |
| |
| Fixed a bug in the UUID library where very rapid calls to the |
| time-based UUID generator could cause duplicate UUID's to be returned. |
| This was not a problem for e2fsprogs, but it could be a problem for |
| other users of the library. |
| |
| Make the UUID library more robust in the face of missing or an |
| improper /dev/urandom or /dev/random files. |
| |
| Added some random portability fixes for Solaris. |
| |
| Some minor man page updates. |
| |
| Fixed a memory leak in the ss library. |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| We now try to use lseek64 and open64 from the LFS if possible. |
| |
| The 3rd parameter in e2p's print_flags is now a flags word, instead of |
| a boolean option. |
| |
| The mark and unmark bitmap functions now return the previous state of |
| the bit that was being changed, which is useful for some speed |
| optimizations. |
| |
| The following functions have been added to enhance the badblocks list |
| handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and |
| ext2fs_badblocks_equal. |
| |
| The ext2 header files now have the latest journalling fields to the |
| superblock. |
| |
| The ext2fs_mkdir function in libext2fs now properly backs out of error |
| conditions robustly. |
| |
| Cleaned up makefiles: |
| - to cleanly compile with the -j flag. |
| - so distclean removes all generated files. |
| - so in case of an error while installing header files, the make aborts. |
| |
| Fix test_script so that it works correctly when compiling in the |
| source directory. |
| |
| The random UUID generation routine has been made slightly better in |
| the case where /dev/random doesn't exist. (Use of randomly-based UUID |
| is still not recommended if /dev/random doesn't exist, however; it's |
| better to use the time/ethernet MAC address UUID in this case.) |
| |
| Clean up the build process so it's more friendly in case of missing |
| directories. |
| |
| The ext2fs header file can now be #include'd into C++ programs. |
| |
| The e2p.h header file is now installed. |
| |
| Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. |
| |
| |
| |
| E2fsprogs 1.18 (November 10, 1999) |
| ================================== |
| |
| Fix a core dumping bug in e2fsck if an imagic inode is present or |
| (more rarely) if the filesystem is badly corrupted enough that e2fsck |
| has to restart pass 1 processing. E2fsck now closes the filesystem |
| before freeing a large number of its data structures, so in the case |
| of future memory faults, at least the fixed filesystem will be fully |
| written out. |
| |
| If a filesystem doesn't support imagic inodes, and e2fsck discovers an |
| imagic inode, it will offer to clear the imagic flag. |
| |
| E2fsck will now offer to clear the immutable flag on special files |
| (device/socket/fifos) when running it in non-preen mode. |
| |
| E2fsck will now set the filetype when creating /lost+found, and when |
| connected orphaned inodes to /lost+found. |
| |
| Debugfs's ncheck and icheck commands now handles the case where there |
| are bad blocks in the inode table without bombing out. |
| |
| The badblocks list processing code has been made more efficiently for |
| appending a large number of (ordered) badblocks to the badblocks list. |
| |
| Some minor man page updates. |
| |
| Fsck now allows interactive e2fsck's when using fsck -As (not a common |
| mode, but some people like to do this in boot scripts for silly reasons). |
| |
| Programmer's notes: |
| ------------------- |
| |
| The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet |
| with the problem code convention. |
| |
| The badblocks list regression test program has been updated to work |
| with previously made API name changes. |
| |
| The ext2fs_free() command now uses the new badblocks API to avoid |
| using the compatibility layer. |
| |
| Added new regression test cases; the run_e2fsck test script now |
| supports the ability for a test case to run a prepratory command |
| before running e2fsck. |
| |
| E2fsprogs 1.17 (October 26, 1999) |
| ================================= |
| |
| Fixed nasty typo in fsck which caused parallelized fsck's to go into an |
| infinite loop. |
| |
| Fixed a bug in fsck where it used strncmp to compare a binary UUID, |
| thus potentially causing problems if a binary UUID contained a NULL |
| character. |
| |
| E2fsck now uses stricter checks for directory entries in pass 2: |
| zero-length filenames are not allowed; neither are 8 byte long |
| directory entries. |
| |
| The debugfs "dirty" command now clears the filesystem valid bit. |
| (Previously this just set the dirty-as-in-needs-writing-out-to-disk |
| bit in the in-core superblock image. The new functionality is more |
| what the user expects, and is more useful.) |
| |
| Added a debugging hook to test parallel fsck; if the environment |
| variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive |
| will be checked in parallel when they normally would not be. |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fixed some #ifdef's for compilation under the Hurd OS. |
| |
| Fixed minor W2K compatibility problems. |
| |
| Fixed some miscellaneous GCC warnings. |
| |
| |
| E2fsprogs 1.16 (October 22, 1999) |
| ================================= |
| |
| Fixed a race condition bug in fsck; when printing a progress bar, if |
| checking multiple filesystems in parallel, it was possible for fsck to |
| send e2fsck a SIGUSR1 signal before e2fsck had installed its signal |
| handler, which would cause it to terminate with a signal 10. |
| |
| E2fsck now properly handles filesystems that have the |
| INCOMPAT_FILETYPE feature turned on. It can be used to convert a |
| filesystem into using or not using FILETYPE feature. |
| |
| E2fsck now properly handles filesystems that have the IMAGIC feature |
| turned on (this is used on Linux AFS servers). |
| |
| The mke2fs program now creates filesystems that have the filetype and |
| sparse_superblock features enabled by default, unless it is run on a |
| pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, |
| so there is now a new flag -O which allows the user to specify with |
| which features she would like to create the filesystem; "mke2fs -O |
| none" will create a filesystsem compatible with 2.0 kernels. |
| |
| The tune2fs program now has a -O option which allows the user to set |
| and reset "safe" filesystem features. Currently, the only ones which |
| allows to be modified are the filetype and sparse_superblock features. |
| Note setting or clearing either feature will require running e2fsck on |
| the filesystem afterwards. (n.b. Clearing the sparse_superblock feature |
| requires that there is enough free space on the filesystem for the |
| extra superblocks which will be created by e2fsck.) |
| |
| Debugfs can now set and print filesystem features in the superblock |
| using the "features" command. Dumpe2fs will print out the complete |
| set of features when listing the superblock. |
| |
| Dumpe2fs has new options -f (force) and -h (header-only). |
| |
| Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead |
| message to come up. This could happen when decrementing or |
| incrementing a link count could result in an overflow. |
| |
| Fixed a bug in e2fsck where the block count on the lost+found |
| directory would not be properly incremented when the directory was |
| expanded to the point where an indirect block needed to be allocated. |
| |
| E2fsck now makes some additional sanity checks on the superblock to |
| avoid crashing or giving a memory allocation error if some of the |
| values in the superblock are unresonable (but the superblock otherwise |
| looks valid). |
| |
| Fixed a bug in e2fsck where a very badly corrupted filesystem might |
| require two passes to completely fix the filesystem. This happened if |
| an inode claimed blocks that was part of the filesystem metadata |
| (typically, when garbage was written into an inode table or indirect |
| block, since this kind of filesystem corruption normally doesn't |
| happen otherwise). |
| |
| On the Alpha, glibc declares st_flags although it isn't actually used; |
| the configure script was improved to detect this case so that |
| e2fsprogs can avoid using the non-functional stat field. |
| |
| The manual pages were updated to use a more consistent formatting |
| style consistent with standard Unix man pages. Mke2fs's man page |
| added documentation for a few previously undocumented options. |
| |
| Fixed minor display bugs in tune2fs and mke2fs. |
| |
| Programmer's notes: |
| ------------------- |
| |
| Improved portability of e2fsprogs to non-Unix systems (in particular, NT). |
| |
| Added features to parse and print feature strings into the e2p library. |
| (e2p_feature2string, e2p_string2feature, e2p_edit_feature). |
| |
| ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories |
| whose directory entries contain proper filetype information if the |
| filesystem supports it. |
| |
| ext2fs_link() now uses the low 3 bits of its flags parameter to pass |
| the directory entry filetype information. This is used to set the |
| directory entry filetype information if the filesystem supports it. |
| |
| Fixed a bug in ext2fs_expand_dir() where the block count in a |
| directory's inode would not be properly incremented when the directory |
| was expanded to the point where an indirect block needed to be |
| allocated. |
| |
| |
| E2fsprogs 1.15 (July 18, 1999) |
| ============================== |
| |
| Add configuration checks so that e2fsprogs will compile cleanly on |
| Linux 2.3 kernels that have renamed i_version to i_generation. |
| |
| E2fsck now prints a progress/completion bar (and not just a simple |
| spinner) if the -C0 option is requested or if it receives a SIGUSR1 |
| signal. Fsck will automatically manage the (potentially muliple) |
| e2fsck processes to print completion bars if it is given a -C option, |
| with the right thing happening if multiple filesystems are being |
| checked in parallel. |
| |
| Mke2fs now has better automatic hueristics to determine the filesystem |
| parameters to be used for a particular filesystem. Added a new option |
| -T which allows the user to specify how the filesystem is to be used, |
| which helps mke2fs do a better job selecting the filesystem parameters. |
| |
| Mke2fs now creates revision 1 filesystems by default, and with the |
| sparse superblock feature enabled. The sparse superblock feature is |
| not understood by Linux 2.0 kernels, so they will only allow read-only |
| mounts of filesystems with this sparse superblocks. |
| |
| Fix bug where if /dev/null couldn't be opened (should never happen), |
| e2fsck would hang in a tight loop. |
| |
| Make e2fsck handle the case where /lost+found isn't a directory. |
| |
| E2fsck now uses mallinfo if it exists to get accurate statistics about |
| its memory usage. |
| |
| Fix bug in e2fsck where it wouldn't check to see if a disconnected |
| inode had any problems before connecting it to /lost+found. |
| |
| Add check to e2fsck so it makes sure that total number of inodes in |
| the filesystem is a sane number. |
| |
| Fix fencepost error when clearing an the end of the block bitmap which |
| caused the last block in the bitmap not to get cleared. |
| |
| Cleaned up a number of messages in e2fsck: |
| * The message "Group's #'s copy of the group descriptor..." |
| was fixed so that the correct number would be displayed. |
| * Added missing space in the "disk write-protected" error messsage |
| * Cleaned up the error message printed when a non-interactive |
| e2fsck needs to abort a check because the filesystem |
| appears to be mounted. |
| |
| Added a new command-line utility, uuidgen, which will create and print |
| a UUID. |
| |
| Make debugfs's icheck command more robust by checking to make sure an |
| inode has valid blocks before interarting over the inode's blocks. |
| |
| UUID generation now uses a random-based scheme whenever possible to |
| prevent potential privacy problems. |
| |
| Man pages for all of the UUID functions in the lirbary were added. |
| |
| Fixed bug in fsck so it won't coredump if a filesystem not in |
| /etc/fstab is given to it. |
| |
| Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab |
| that most of the other mount utilities understands. |
| |
| Mke2fs will make a filesystem even if it appears mounted if the force |
| option is given. |
| |
| Dumpe2fs has new command-line options which allow a filesystem expert |
| to specify the superblock and blocksize when opening a filesystem. |
| This is mainly useful when examining the remains of a toasted |
| filesystem. |
| |
| The badblocks program has been updated to display correctly on disks |
| with large block numbers. |
| |
| The badblocks program no longer gives spurious errors when errors |
| occur on non-block boundaries, which is common if the blocksize is |
| larger than 1k. |
| |
| Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the |
| MKE2FS_SYNC environment variable is set. This is to work around a VM |
| bug in the 2.0 kernel. I've heard a report that a RAID user was able |
| to trigger it even using a 2.2 kernel, but hopefully it will not be |
| needed for most Linux 2.2 users. |
| |
| Fixed miscellaneous documentation and man pages. |
| |
| Programmer's notes: |
| ------------------- |
| |
| Cleaned up functions such as pass1_get_blocks, pass1_read_inode which |
| in e2fsck's pass1.c really should have been static. |
| |
| The return value of the uuid_compare() function was changed to make it |
| match with the convetions used by strcmp, memcmp, and Paul Leach's |
| UUID sample document. |
| |
| The "make depend" process has now been made more automated; it now |
| automatically word-wraps the dependencies, and only replaces source |
| Makefile.in if there has been a change in the dependencies. Also, a |
| top-level "make depend" now recurses through all the subdirectories |
| automatically. |
| |
| The Makefile in .../util has been changed so that subst is built using |
| the native C compiler during a cross-compilation, since the subst |
| program is only used during the build process. Also add an explicit |
| rule to build util/subst by cd'ing to the correct directory and |
| running Makefile. |
| |
| The man directories are defined in terms mandir, so that the configure |
| script can override the location of the manual pages. |
| |
| The config files have been updated to recognize new machine types for |
| both the i386 and alpha families. |
| |
| Fsck has been modified so that it will accurately create an |
| fsck_instance even when the noexecute flag is set. This allows for |
| accurate debugging of the fsck pass structure. Also, when the verbose |
| flag is given twice, fsck will print debugging information about when |
| fsck is waiting for jobs to finish. |
| |
| |
| E2fsprogs 1.14 (January 9, 1999) |
| ================================ |
| |
| Fix the fstab parsing code so that it can handle blank lines and |
| comment characters. Also, missing pass numbers need to be treated as |
| zero. |
| |
| Fixed a bug in e2fsck where under some circumstances (when e2fsck |
| needs to restart processing after fixing an egregious inconsistency) |
| it would try to access already freed memory. |
| |
| E2fsck now prints non-printable characters in directory entries and |
| pathnames using '^' and 'M-' notation. |
| |
| Fixed chattr so that it will ignore symbolic links when doing |
| recursive descent traversals. For both chattr and lsattr, no longer |
| print the version string unless the -V option is given. |
| |
| Allow the system administrator to directly specify the number of |
| inodes desired in the filesystem, for some special cases where this is |
| necessary. |
| |
| Fix portability problems so that e2fsprogs can be compiled under Linux |
| 1.2 systems and Solaris systems. |
| |
| Update the config.guess file with a more recent version that will |
| identify newer Linux platforms. |
| |
| Programmer's notes |
| ------------------ |
| |
| Ext2fs_read_inode and ext2fs_write_inode will now return an error if |
| an inode number of zero is passed to them. |
| |
| E2fsprogs 1.13 (December 15, 1998) |
| ================================== |
| |
| Fixed a bug in debugfs where an error messages weren't getting printed |
| when the ext2 library routines to read inodes returned errors in the |
| stat, cmri and rm commands. |
| |
| Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is |
| provided, it won't create an inode table smaller than the minimum |
| number of inodes required for a proper ext2 filesystem. |
| |
| Fsck now parses the /etc/fstab file directly (instead of using |
| getmntent()), so that it can distinguish between a missing pass number |
| field and pass number field of zero. This caused problems for |
| diskless workstations where all of the filesystems in /etc/fstab have |
| an explicit pass number of zero, and fsck could not distinguish this |
| from a /etc/fstab file with missing pass numbers. |
| |
| E2fsck will create a /lost+found directory if there isn't one in the |
| filesystem, since it's safer to create the lost+found directory before |
| it's needed. |
| |
| Fixed e2fsck so that it would detect bogus immutable inodes which |
| happen to be sockets and FIFO files, and offer to clear them. |
| |
| If a filesystem has multiple reasons why it needs to be checked, and |
| one of the reasons is that it is uncleanly mounted, e2fsck will print |
| that as the reason why the filesystem is being checked. |
| |
| Cleaned up the output routines of mke2fs so that it doesn't overflow |
| an 80 column display when formating really big filesystems. |
| |
| Added a sanity check to e2fsck to make sure that file descriptors 0, |
| 1, 2 are open before opening the hard disk. This avoids a problem |
| where a broken program might exec e2fsck with those file descriptors |
| closed, which would cause disastrous results if the kernel returns a |
| file descriptor for the block device which is also used by FILE * |
| stdout. |
| |
| Fixed up the e2fsck progress reporting functions so that the values |
| reliably reach 100% at the completion of all of the e2fsck passes. |
| |
| Fixed minor documentation bugs in man pages and usage messages. |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fixed a number of lint warnings in the ext2fs library and potential |
| portability problems from other OS's header files that might define |
| CPP macros for names like "max" and "min". |
| |
| ext2fs_badblocks_list_add() has been made more efficient when it needs |
| to grow the bad blocks list. |
| |
| Fixed a bug in e2fsck which caused it to dereference a freed pointer |
| just before exiting. |
| |
| Fixed the substition process for generating the mk_cmds and compile_et |
| scripts so that they will work outside of the build tree. |
| |
| Add sanity check to e2fsck so that if an internal routine |
| (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer |
| and causing a core dump. This should never happen, but... |
| |
| E2fsprogs 1.12 (July 9, 1998) |
| ================================== |
| |
| E2fsprogs now works with glibc (at least with the version shipped wtih |
| RedHat 5.0). The ext2fs_llseek() function should now work even with |
| i386 ELF shared libraries and if llseek() is not present. We also |
| explicitly do a configure test to see if (a) llseek is in libc, and |
| (b) if llseek is declared in the system header files. (See standard |
| complaints about libc developers don't understand the concept of |
| compatibility with previous versions of libc.) |
| |
| The ext2fs library now writes out the block group number in each of |
| the superblock copies. This makes it easier to automatically |
| determine the starting block group of the filesystem when the block |
| group information is trashed. |
| |
| Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, |
| which means that e2fsprogs will ignore the high 8 bits of the |
| directory entry's name_len field, so that it can be used for other |
| purposes. |
| |
| Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. |
| E2fsprogs will now support filesystems with 64-bit sized files. |
| |
| Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. |
| |
| Added new program "e2label", contributed by Andries Brouwer. E2label |
| provides an easy-to-use interface to modify the filesystem label. |
| |
| Fixed bug so that lsattr -v works instead of producing a core dump. |
| |
| Fixed a minor bug in mke2fs so that all groups with bad superblock |
| backup blocks are printed (not just the first one). |
| |
| Mke2fs will check the size of the device, and if the user specifies a |
| filesystem size larger than the apparent size of the device it will |
| print a warning message and ask if the user wants to proceed. |
| |
| E2fsck has a new option -C, which sends completion information to the |
| specified file descriptor. For the most part, this is intended for |
| programs to use, although -C 0 will print a spinning character to the |
| stdout device, which may be useful for users who want to see something |
| happening while e2fsck goes about its business. |
| |
| Fixed a bug in e2fsck which could cause a core dump when it needs to |
| expand the /lost+found directory, and sometimes the bitmaps haven't |
| been merged in. Also fixed a related bug where ext2fs_write_dir_block |
| was used to write out a non-directory block. (Which would be bad on a |
| non-Intel platform with byte swapping going on.) |
| |
| Fixed bug in e2fsck where it would print a "programming error" message |
| instead of correctly identifying where a bad block was in used when |
| the bad block was in a non-primary superblock or block group |
| descriptor. Also fixed a related bug when sparse superblocks are in |
| use and there is a bad block where a superblock or block group |
| descriptor would have been in a group that doesn't include a |
| superblock. |
| |
| Fixed a bug in e2fsck (really in libext2fs's dblist function) where if |
| the block group descriptor table is corrupt, it was possible to try to |
| allocate a huge array, fail, and then abort e2fsck. |
| ext2fs_get_num_dirs() now sanity checks the block group descriptor, |
| and subsitutes reasonable values if the descriptors are obviously bogus. |
| |
| If e2fsck finds a device file which has the immutable flag set and the |
| i_blocks beyond the normal device number are non-zero, e2fsck will |
| offer to remove it, since it's probably caused by garbage in the inode |
| table. |
| |
| When opening a filesystem, e2fsck specially checks for the EROFS error |
| code, and prints a specific error message to the user which is more |
| user friendly. |
| |
| If the filesystem revision is too high, change the e2fsck to print |
| that this is either because e2fsck is out of date, or because the |
| superblock is corrupt. |
| |
| E2fsck now checks for directories that have duplicate '.' and '..' |
| entries, and fixes this corruption. |
| |
| E2fsck no longer forces a sync of the filesystem (with attendant sleep |
| calls) at all times. The ext2fs_flush() function now performs a sync |
| only if it needed to write data blocks to disk. |
| |
| Fixed a minor bug in e2fsck's pass1b's file cloning function, where |
| certain errors would not be properly reported. |
| |
| Updated and expanded a few points in the man pages which users |
| complained wheren't explicit enough. |
| |
| Added special case byte-swapping code if compiling on the PowerPC, to |
| accomodate the strange big-endian variant of the ext2 filesystem that |
| was previously used on the PowerPC port. |
| |
| |
| Programmer's notes: |
| ------------------- |
| |
| Removed C++ keywords from the ext2fs libraries so that it could be |
| compiled with C++. |
| |
| E2fsck's internal organization has now been massively reorganized so |
| that pass*.c don't have any printf statements. Instead, all problems |
| are reported through the fix_problem() abstraction interface. E2fsck |
| has also been revamped so that it can be called as a library from a |
| application. |
| |
| Added new fileio primitives in libext2fs for reading and writing |
| files on an unmounted ext2 filesystem. This interface is now used by |
| debugfs. |
| |
| Added a new libext2fs function for mapping logical block numbers of |
| a file to a physical block number. |
| |
| Added a new libext2fs function, ext2fs_alloc_block(), which allocates |
| a block, zeros it, and updates the filesystem accounting records |
| appropriately. |
| |
| Added a new libext2fs function, ext2fs_set_bitmap_padding(), which |
| sets the padding of the bitmap to be all one's. Used by e2fsck pass 5. |
| |
| The libext2fs functions now use a set of memory allocation wrapper |
| functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, |
| instead of malloc, free, and resize. This makes it easier for us to |
| be ported to strange environments where malloc, et. al. aren't |
| necessarily available. |
| |
| Change the libext2fs fucntion to return ext2-specific error codes |
| (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using |
| and depending on the existence of system error codes (such as EEXIST |
| and ENOENT). |
| |
| Renamed io.h to ext2_io.h to avoid collision with other OS's header |
| files. |
| |
| Add protection against ext2_io.h and ext2fs.h being included multiple |
| times. |
| |
| The types used for memory lengths, etc. have been made more portable. |
| In generla, the code has been made 16-bit safe. Added Mark |
| Habersack's contributed DOS disk i/o routines. |
| |
| Miscellaneous portability fixes, including not depending on char's |
| being signed. |
| |
| The io_channel structure has a new element, app_data, which is |
| initialized by the ext2fs routines to contain a copy of the filesystem |
| handle. |
| |
| ext2fs_check_directory()'s callback function may now return the error |
| EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to |
| really do the checking, despite the presence of the callback function. |
| |
| |
| E2fsprosg 1.11 (June 17, 1997) |
| ============================== |
| |
| Fixed e2fsck to detect (previously ignored) conflicts between the |
| superblock or block group descriptors and block bitmaps, inode |
| bitmaps, and inode tables. |
| |
| Fixed bug in e2fsck so that when the message printed out when a block |
| or inode bitmap conflicts with other data, it has the correct group |
| number. |
| |
| Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed |
| to badblocks. This meant that not all of the filesystem was being |
| tested for bad blocks! |
| |
| Fixed an array boundary overrun case which cropped up in |
| ext2fs_badblocks_list_test when a user tried running "mke2fs -c |
| -b 4096". |
| |
| Adjusted the number of columns printed by mke2fs when displaying the |
| superblock backups to avoid running over 80 columns when making a |
| really big filesystem. |
| |
| Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, |
| dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar |
| fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). |
| |
| Programmer's notes: |
| ------------------- |
| |
| Fixed install rule in lib/ss so that ss_err.h is actually getting |
| installed. |
| |
| Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting |
| bassed back to the caller. |
| |
| Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been |
| setting the current inode number (which meant this function wasn't |
| working at all). |
| |
| Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all |
| blocks in the bitmap when increasing the size of the bitmap. |
| |
| Changed the initial number of blocks allocated by ext2fs_init_dblist() |
| to be more realistic. |
| |
| Added a new function ext2fs_allocate_group_table, which sets up the |
| group descriptor information (and allocates inode and block bitmaps, |
| and inode tables for a particular group). The function was created by |
| factoring out code form ext2fs_allocate_tables(). |
| |
| Added a new function ext2fs_move_blocks which takes a bitmap of the |
| blocks to be moved, and moves them to another location on the |
| boardboard. |
| |
| Make the unix_io channel's io_channel_flush implementation calls sync() |
| to to flush the kernel buffers to disk. |
| |
| Added a new function ext2fs_dblist_count returns the number of |
| directory blocks in dblist. |
| |
| |
| E2fsprogs 1.10 (April 24, 1997) |
| =============================== |
| |
| Mke2fs once again defaults to creating revision #0 filesystems, since |
| people were complaining about breaking compatibility with 1.2 kernels. |
| Warning messages were added to the mke2fs and tune2fs man pages that |
| the sparse superblock option isn't supported by most kernels yet (1.2 |
| and 2.0 both don't support parse superblocks.) |
| |
| Added new flag to mke2fs, -R <raid options>, which allows the user to |
| tell mke2fs about the RAID configuration of the filesystem. Currently |
| the only supported raid option is "stride" which specifies the width |
| of the RAID stripe. |
| |
| Fixed bug in e2fsck where pass1b would bomb out if there were any |
| blocks marked bad in the inode table. |
| |
| Fixed rare bug in mke2fs where if the user had a very unlucky number |
| of blocks in a filesystem (probability less than .002) the resulting |
| filesystem would be corrupt in the last block group. |
| |
| Fixed bug where if e2fsck tried to allocate a block to fix a |
| filesystem corruption problem and the filesystem had no free blocks, |
| ext2fs_new_block() would loop forever. |
| |
| The configure script now checks explicitly to see if "-static" works, |
| since that can't be assumed to be true --- RedHat doesn't install |
| libc-static by default. |
| |
| Fixed bug in libext2's block iterator functions where under some |
| cirmcustances, file with holes would cause the bcount parameter to the |
| callback function to be incorrect. This bug didn't affect any of |
| e2fsprogs programs, but it was discovered by Paul Mackerras, the |
| author of the PPC boot loader. |
| |
| Removed use of static variables to store the inode cache in libext2fs. |
| This caused problems if more than one filesystem was accessed via |
| libext2fs (static variables in libraries are generally a bad idea). |
| Again, this didn't affect e2fsprogs programs, but it was discovered by |
| Paul Mackerras. |
| |
| Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 |
| will compile cleanly with 1.2.13 kernels (even with a.out shared |
| libraries!) |
| |
| Programmer's notes: |
| ------------------- |
| |
| Added new functions to duplicate an ext2 filesystem handle, and its |
| associated substructure. New functions: ext2fs_dup_handle(), |
| ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). |
| Other structures, such as the io_channel and the inode_cache, now have |
| a ref count so that they only get freed when they are no longer used |
| by any filesystem handle. (These functions were added as part of the |
| development effort for an ext2 resizer). |
| |
| E2fsprogs 1.09 (April 14, 1997) |
| =============================== |
| |
| Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was |
| accidentally introduced in the 1.08 release. The overhead calculation |
| was accidentally removed, which caused ext2fs_initialize() to not |
| notice when the filesystem size needed to be adjusted down because |
| there wasn't enough space in the last block group. |
| |
| Fixed bug in version parsing library routine; it was always parsing |
| the library version string, instead of using the passed-in string. |
| |
| Clarified chattr man page. |
| |
| E2fsprogs 1.08 (April 10, 1997) |
| =============================== |
| |
| E2fsck 1.07 was very slow when checking very large filesystems with a |
| lot of files that had hard links (i.e., news spools). This was fixed |
| by seriously revamping the icount abstraction. Added a formal test |
| suite for the icount abstraction. |
| |
| Debugfs now has a "-l" option to the "ls" command, which lists the |
| inode number, permissions, owner, group, size, and name of the files |
| in the directory. |
| |
| Fix a bug in e2fsck where when a directory had its blocks moved to |
| another location during the pass 1b processing, the directory block |
| list wasn't updated, so pass 2 wouldn't check (and correct) the |
| correct directory block. |
| |
| E2fsck will now treat inodes which contain blocks which are claimed by |
| the filesystem metadata by treating them as multiply claimed blocks. |
| This way, the data in those blocks can be copied to a new block during |
| the pass 1b--1d processing. |
| |
| E2fsck will attempt to determine the correct superblock number and |
| display it in the diagnostic and warning messages if possible. |
| |
| Add support for a new (incompatible) feature, "sparse_super". This |
| feature reduces the number of blocks which contain copies of backup |
| superblocks and block group descriptors. (It is only an incompatible |
| feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now |
| support a new -s option; e2fsck will recognize filesystems built with |
| this feature turned on. |
| |
| E2fsck now checks the library to make sure is the correct version, |
| using new library functions. (This helps to diagnose incorrectly |
| installed e2fsprogs distributions.) |
| |
| Dumpe2fs now prints more information; its now prints the the |
| filesystem revision number, the filesystem sparse_super feature (if |
| present), the block ranges for each block group, and the offset from |
| the beginning of the block group. |
| |
| Mke2fs now distributes the inode and block bitmap blok so that the |
| won't be concentrated in one or two disks in RAID/striping setups. |
| Also, if the user chooses a 2k or 4k block group, mke2fs will try to |
| choose the largest blocks per group that be chosen. (For 2k blocks, |
| you can have up to 16384 blocks/group; for 4k blocks, you can have up |
| to 32768 blocks/group.) Previously mke2fs would not allow |
| specification of more than 8192 blocks per group, even if you were |
| using a 2k or 4k block group. |
| |
| Programmer's notes: |
| ------------------- |
| |
| Added a new function ext2fs_create_icount2() which takes a "hint" |
| argument. This hint argument presets the icount array with the list |
| of inodes which actually need to be in the icount array. This really |
| helps to speed up e2fsck. |
| |
| Added a new function ext2fs_icount_validate() which checks the rep |
| invariant for the icount structure. This is used mostly for testing. |
| |
| The error mesasage given when a bad inode number is passed to |
| test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of |
| EXT2FS_UNMARK_ERROR). |
| |
| Added a new function ext2fs_set_dir_block which sets the block of a |
| dblist entry, given the directory inode and blockcnt. |
| |
| Added a new function ext2fs_get_library_version() which returns the |
| current library version, and ext2fs_parse_version_string() which |
| returns a version number based on a e2fsprogs version string. |
| |
| The icount functions will return EINVAL if the passed in inode number |
| is out of bounds. |
| |
| E2fsprogs 1.07 (March 9, 1997) |
| ============================== |
| |
| E2fsck is now uses much less memory when checking really large |
| filesystems (or rather, filesystems with a large number of inodes). |
| Previously a filesystem with 1 million inodes required 4 megabytes of |
| memory to store inode count statistics; that storage requirement has |
| now been reduced to roughly half a megabyte. |
| |
| E2fsck can now properly deal with bad blocks appearing inside the |
| inode table. Instead of trying to relocate the inode table (which |
| often failed because there wasn't enough space), the inodes in the bad |
| block are marked as in use. |
| |
| E2fsck will automatically try to use the backup superblocks if the |
| primary superblocks have a bad magic number or have missing meta-data |
| blocks (or meta-data blocks which are out of range). |
| |
| E2fsck's pass 3 has been made more efficient; most noticeable on |
| filesystems with a very large number of directories. |
| |
| Completely revamped e2fsck's system of printing problem reports. It |
| is now table driven, to make them more easily customizeable and |
| extendable. Error messages which can be printed out during preen mode |
| are now one line long. |
| |
| Fixed e2fsck's filesystem swapping code so that it won't try to swap |
| fast symbolic links or deleted files. |
| |
| Fixed e2fsck core dumping when fixing a filesystem which has no |
| directories (not even a root directory). |
| |
| Added a check to e2fsck to make sure that the length of every |
| directory entry is a multiple of 4 (since the kernel complains if it |
| isn't). |
| |
| Added a check to e2fsck to make sure that a directory entry isn't a |
| link to the root directory, since that isn't allowed. |
| |
| Added a check to e2fsk to now make sure the '.' and '..' directory |
| entries are null terminated, since the 2.0 kernel requires it. |
| |
| Added check to write_bitmaps() to make sure the superblock doesn't get |
| trashed if the inode or block bitmap is marked as being block zero. |
| |
| Added checking of the new feature set fields in the superblock, to |
| avoid dealing with new filesystem features that this package wasn't |
| set up to handle. |
| |
| Fixed a fencepost error in ext2fs_new_block() which would occasionally |
| try to allocate a block beyond the end of a filesystem. |
| |
| When the UUID library picks a random IEEE 802 address (because it |
| can't find one from a network card), it sets the multicast bit, to |
| avoid conflicting with a legitimate IEEE 802 address. |
| |
| Mke2fs now sets the root directory's owner to be the real uid of the |
| user running mke2fs. If the real uid is non-zero, it also sets |
| the group ownership of the root directory to be the real group-id of |
| the user running mke2fs. |
| |
| Mke2fs now has more intelligent error checking when it is given a |
| non-existent device. |
| |
| When badblocks is given the -vv option, it now updates the block that |
| it is currently testing on every block. |
| |
| Fixed a bug in fsck where it wouldn't modify the PATH envirnoment |
| currently correctly if PATH wasn't already set. |
| |
| Shared libraries now built with dependencies. This allows the shared |
| library files to be used with dlopen(); it also makes the transition |
| to libc 6 easier, since ld.so can tell which libc a particular shared |
| library expects to use. |
| |
| Programmer's notes: |
| ------------------- |
| |
| Added new abstraction (defined in dblist.c) for maintaining a list of |
| blocks which belongs to directories. This is used in e2fsck and other |
| programs which need to iterate over all directories. |
| |
| Added new functions which test to see if a contiguous range of blocks |
| (or inodes) are available. (ext2fs_*_bitmap_range). |
| |
| Added new function (ext2_inode_has_valid_blocks) which returns true if |
| an inode has valid blocks. (moved from e2fsck code). |
| |
| Added new function (ext2fs_allocate_tables) which allocates the |
| meta-data blocks as part of initializing a filesystem. (moved from |
| mke2fs code). |
| |
| Added a new I/O manager for testing purposes. It will either allow a |
| program to intercept I/O requests, or print debugging messages to |
| trace the activity of a program using the I/O manager. |
| |
| The badblocks_list functions now store the bad blocks in a sorted |
| order, and use a binary search to speed up badblocks_list_test. |
| |
| The inode scan function ext2fs_get_next_inode() may now return a soft |
| error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in |
| those cases where part of an inode table is missing or there is a bad |
| block in the inode table. |
| |
| Added a new function (ext2fs_block_iterate2) which adds new arguments to |
| the callback function to return a pointer (block and offset) to the |
| reference of the block. |
| |
| Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an |
| application to jump to a particular block group while doing an inode |
| scan. |
| |
| The badblocks list functions were renamed from badblocks_* to |
| ext2fs_badblocks_*. Backwards compatibility functions are available |
| for now, but programs should be modified to use the new interface. |
| |
| Some of the library functions were reorganized into separate files to |
| reduce the size of some programs which statically link against the |
| ext2 library. |
| |
| Put in some miscellaneous fixes for the Alpha platform. |
| |
| |
| E2fsprogs 1.06 (October 7, 1996) |
| ================================ |
| |
| Fixed serious bug in e2fsck: if the block descriptors are bad, don't |
| smash the backup copies in ext2fs_close(). (The problem was that when |
| e2fsck -p discovered the problem, while it was closing the filesystem |
| and exiting, it was also blowing away the backup superblocks on the |
| disk, which was less than friendly.) We now make it the case that we |
| only write out the backup superblock and the back block descriptors if |
| the filesystem is completely free from problems. |
| |
| Fixed a bug in block_interate in the lib/ext2fs library which caused |
| e2fsck to fail on GNU Hurd-created filesystems. |
| |
| Add support for Linux/FT's bootloader, which actually uses |
| EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want |
| to clear the inode. |
| |
| Add support for the "A" (no atime update) attribute. (Note: this |
| attribute is not yet in production kernels.) |
| |
| The test suite is not automatically run when doing a "make all" from |
| the top level directory. Users should manually run "make check" if |
| they wish to run the test suite. |
| |
| Upon a preenhalt(), make the printed message more explicit that |
| running e2fsck "MANAULLY" means without the -p or -a options. |
| |
| In e2fsck, if a disconnected inode is zero-length, offer to clear it |
| instead of offering to connect it to lost+found. |
| |
| In e2fsck, if a filesystem was just unmounted uncleanly, and needs |
| e2fsck to be run over it, change e2fsck to explicitly display this |
| fact. |
| |
| For dumpe2fs and e2fsck, cause the -V option to print out which |
| version of the ext2fs library is actually getting used. (This will |
| help detect mismatches of using a 1.06 utility with a 1.05 library, |
| etc.) |
| |
| Programmers' notes: |
| ------------------- |
| |
| EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits |
| the naming convention. |
| |
| In ext2fs_initialize(), make sure the description for the inode bitmap |
| is correctly initialize. |
| |
| Fixed minor type typo in ext2fs_allocate_generic_bitmap(); |
| |
| E2fsprogs 1.05 (September 7, 1996) |
| ================================== |
| |
| Add support for new fields in the ext2 superblock --- volume name, |
| volume UUID, and last mounted field. Dumpe2fs displays these fields, |
| tune2fs and mke2fs allows you to set them. E2fsck will automatically |
| generate a UUID for those volumes that don't have them. |
| |
| Put in support for e2fsck to recognize HURD specific ext2 features --- |
| most notably, the translator block. The e2fsprogs tools will now use |
| the creator_os field in the superblock to correctly handle different |
| OS-specific variants of the ext2 filesystem. |
| |
| E2fsck now fixes inodes which have a the deletion time set, but which |
| have a non-zero i_link_count field by offering to clear the deletion |
| time. Previously e2fsck assumed that the inode was deleted (per 0.3c |
| ext2 kernel behavior) and offered to unlink the file. |
| |
| If e2fsck sets the clean bit, but nothing else, set the exit code |
| FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it |
| set the filesystem valid bit when it was previously cleared. :-) This |
| was needed to make the HURD fsck driver happy. |
| |
| If the user refuses to attach an unattached inode, e2fsck will no |
| longer set the inode's link count. Otherwise, the inode would end up |
| getting marked as unused, which might cause loss of data later. |
| |
| Make the message issued by e2fsck when the superblock is corrupt less |
| confusing for users. It now mentions that another reason for the |
| "corrupt superblock" message might be that the partition might not be |
| an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) |
| |
| Make the libext2 library more robuest so that e2fsck won't coredump on |
| an illegal superblock where the blocksize is zero. (f_crashdisk is |
| the test case). |
| |
| By default, create filesystems where the default checkinterval is 6 |
| months (180 days). Linux servers can be robust enough that 20 reboots |
| can be a long, long time. |
| |
| Added configure flag --enable-old-bitops, which forces the bitops to |
| use the old (native) bitmask operations. By default on the sparc |
| platform, the standard ext2 bit ordering is now used. |
| |
| Added a new feature to e2fsck to byte-swap filesystems; this can be |
| used to convert old m68k filesystems to use the standard byte-order |
| storage for the superblock, inodes, and directory blocks. This |
| function is invoked by using the '-s' option to e2fsck. |
| |
| Debugfs's "dump" command has been enhanced so that it writes out the |
| exact size of the file so that the nulls at the end of the file are |
| eliminated. The command also accept a new "-p" option which will |
| attempt preserve to preserve the ownernship, permissions, and |
| file modification/access times. |
| |
| Debugfs has two new options, -f and -R. The -R option allows the user |
| to execute a single debugfs command from the command line. The -f |
| option allows the user to specify a "command file" containing debugfs |
| commands which will get executed. |
| |
| Dumpe2fs now pretty prints the check interval, instead of just |
| printing the check interval as a number of seconds. |
| |
| Fix bugs in debugfs: the params command when no filesystem is opened |
| no longer causes a core dump. It is now possible to unlink a file |
| when a pathame containing a '/' is specified. |
| |
| Tune2fs has a new -C option which sets the number of times the |
| filesystem has been mounted. |
| |
| Fix the chattr '-v' option so that it actually works. Chattr was |
| being buggy about the -v option parsing. |
| |
| Programmers' notes: |
| ------------------- |
| |
| The directory lib/uuid contains a set of library routines to generate |
| DCE compatible UUIDs. |
| |
| Extended ext2fs_namei() to handle symbolic links. Added new function |
| ext2fs_nami_follow() which will follow last symbolic link in the case |
| where the pathname points to a sym link. |
| |
| The ext2fs_block_iterate function will now return the HURD translator |
| block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the |
| iterator to return data blocks only. The ext2fs.h file now defines |
| constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and |
| BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block |
| count field of the iterator callback function. |
| |
| The test script driver now takes an optional second argument, which is |
| the test case to be run. This allows you to run a test case without |
| needing to run the entire test suite. |
| |
| On Linux ELF systems, install the .so files in the correct places |
| (/usr/lib). The .so files must be stored in the same directory as the |
| .a files. |
| |
| Fixed miscellaneous HURD compilation issues with header file being |
| included in the right order. |
| |
| Fixed debugfs so that it resets optind to zero, not one, since setting |
| optind to zero is more correct. |
| |
| |
| E2fsprogs 1.04 (May 16, 1996) |
| ============================= |
| |
| First "official" (1.03 was a limited release only) to support building |
| e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 |
| kernels). |
| |
| This package includes a RPM specs file, that it can be built using the |
| RedHat Package Manager. |
| |
| E2fsck now prints a hint that if there are lots of incorrectly located |
| inode bitmaps, block bitmaps, and inode table blocks, the user might |
| want to try using e2fsck -b 8193 first, to see if that fares any |
| better. |
| |
| For ext2 filesystem written with the hurd, debugfs will now print out |
| the translator field when printing an inode structure. |
| |
| Lots of miscellaneous linking/installation cleanups: |
| |
| Libraries are now linked using a relative pathname, instead of |
| relying on -L working correct. It doesn't, in many cases, including |
| current versions of GNU ld. This guarantees that the build tree is |
| linking with the right libraries, instead of the ones installed in |
| /usr/lib. |
| |
| Header files, man pages, and the et/ss shell scripts are now |
| generated using a custom substitution script, instead of relying on |
| the configure script. This prevents needless recompilation of |
| files; in addition, the custom substitution script is much faster. |
| |
| e2fsck may now be linked dynamically, by using the |
| --enable-dynamic-e2fsck flag to configure. This is not recommended, |
| since it increases e2fsck's dependence on other files, but some |
| people need to save disk space, and other critical programs on their |
| systems were being linked dynamically anyway. |
| |
| Programs such as fsck which didn't need to be linked against |
| libext2fs (or mke2fs which didn't need to be linked against libe2p) |
| only link against libraries they actually need. Otherwise, those |
| programs would require the presense of libraries that otherwise |
| could be removed from a rescuse diskette. |
| |
| The ss include files are now installed correctly so they can |
| actually be used by another package. |
| |
| If the profiling libraries are built, they are now installed on a |
| "make install-libs". |
| |
| |
| E2fsprogs 1.03 (March 27, 1996) |
| =============================== |
| |
| Change the m68k bit numbering for bitmasks to match the bit numbering |
| used by all other ext2 implementations. (This change was requested by |
| the m68k kernel development team.) |
| |
| Support (in-development) filesystem format revision which supports |
| (among other things) dynamically sized inodes. |
| |
| Fixed a bug in the ext2 library so that an intelligent error is |
| returned if mke2fs is run with a ridiculously small number of blocks |
| for a partition. |
| |
| Fixed a bug in the ext2 library which required that the device be |
| openable in read/write mode in order to determine its size. This |
| caused e2fsck -n to require read/write access when it was not |
| previously necessary. |
| |
| Fixed a bug in e2fsck which casued it to occasionally fail the test |
| suite depending on which version of the floating point library it was |
| using. |
| |
| Fixed a bug in e2fsck so that it now halts with a fatal error when |
| certain superblock consistency checks fail. Previously it continued |
| running e2fsck, with some potential confusing/damaging consequences. |
| |
| Added new flag to fsck which allows the root to be checked in parallel |
| with other filesytems. This is not the safest thing in the world to |
| do, but some system administrators really wanted it. |
| |
| Fixed -Wall flames in lib/ss. |
| |
| |
| E2fsprogs 1.02 (January 16, 1996) |
| ================================= |
| |
| Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. |
| |
| Change e2fsck to print statistics of how many non-contiguous files are |
| on the system. Note that a file which is larger than 8k blocks, it is |
| guaranteed to be non-contiguous. |
| |
| In mke2fs, print a warning message if a user tries to format a whole |
| disk (/dev/hda versus /dev/hda1). If a user really wants to format a |
| whole disk, the -F (force) option forces mke2fs to format a whole disk |
| as a filesytem. |
| |
| Fix a bug in fsck where in some cases it might start checking |
| partitions in the next pass before it finishes checking partitions in |
| the current pass. This still won't cause two partitions on the same |
| disk will be checked, so it's rarely a problem in real life. |
| |
| Patch lsattr so that it won't hang when checking a named pipe. |
| |
| Minor compilation fixes: |
| * Fix the order of libraries that were linked in debugfs. |
| * Allow the sources to be compiled with -ansi turned on. |
