| 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 Sweedish 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. |
