| 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. |
