-E2fsprogs 1.43-WIP (March 14, 2016) -- f8fd2fdc1e
-=================================================
-
-Add support for the ext4 metadata checksum, checksum seed, inline
-data, encryption, project quota, and read-only features.
-
-Support for the very old, experimental, and never-added-to-mainline
-compression feature has been removed.
-
-Mke2fs will now create file systems with the metadata_csum and 64bit
-features enabled by default.
-
-The tune2fs program will ask the user for confirmation before starting
-dangerous operations if the terminal is available, and it will replay
-the journal if necessary.
-
-Add an ext2/3/4 FUSE server
-
-Debugfs can now modify extended attributes and journal transactions.
-
-Debugfs now can properly display and set extended timestamps.
-
-E2fsck will offer to fix extended timestamps that were incorrectly
-encoded by older kernels.
-
-Fix miscellaneous MMP bugs in debugfs.
-
-The resize2fs command can now convert file systems between 64-bit and
-32-bit mode.
-
-We now use a new e2undo file format which is much more efficient and
-faster than the old tdb-based scheme. Since it so much faster,
-e2fsck, tune2fs, debugfs, and resize2fs now also can support using
-creating an undo file.
-
-The mke2fs command can now set the error behavior when initializing
-the file system (so the administrator doesn't have to issue a separate
-tune2fs -e command).
-
-Teach mke2fs to parse a human-readable argument for -i option.
-
-Teach mke2fs to automatically handle creating file systems > 500T by
-automatically enable the meta_bg feature.
-
-Mke2fs will now prompt for user verification before rewriting a file
-system's superblock using the -S option.
-
-Mke2fs no longer complains if the user tries to create a file system
-using the entire block device (e.g., without using a partition). The
-minor number convention is not used by all block devices, and it's
-quite normal in some circumstances to create a file system on /dev/sdc
-instead of /dev/sdc1.
-
-Fix an "mke2fs -d" bug which could create inodes with invalid
-extended attribute blocks
-
-E2fsck is now much more paranoid about not freeing or corrupting
-critical metadata blocks, such as inode table blocks, even if
-corrupted indirect blocks or extent trees point at these blocks.
-
-E2fsck now prints block ranges in pass1b instead of listing all of the
-blocks exhaustively.
-
-E2fsck will try to expand the root directory if the lost+found can't
-be linked to the root directory. Also, offer to use the root
-directory if lost+found can't be created.
-
-E2fsck is now more paranoid handling corrupted extent trees as well as
-corrupted journals.
-
-E2fsck can now rebuild extent trees, either (a) to optimize them, (b)
-to recover from a corrupted extent tree, or (c) to convert
-block-mapped inodes to use extents.
-
-E2fsck now has a readahead mechanism which can significantly speed its
-performance, especially on RAID arrays.
-
-E2fsck now has a "yes to all" option which the user can give if she is
-tired of answering 'y' to a very large number of questions.
-
-E2fsck will now ignore the badblocks inode if the contents of the
-badblocks inode indicate that the portion inode table containing the
-badblocks inode is bad. (We must go deeper...)
-
-E2fsck can now correctly fix directory with holes on bigalloc file
-systems.
-
-E2fsck will now check for extent mapped inodes with no extent header
-and clear them if found.
-
-E2fsck now checks to make sure the extended attribute header doesn't
-result in the xattr extending beyond the bounds of the inode
-
-Fixed a bug in e2fsck to avoid overrunning a buffer containing jbd2
-revoke records if the journal is corrupted.
-
-Fixed a bug in e2fsck which could cause it loop forever if a special
-inode has too many invalid block mappings.
-
-Fixed a bug in e2fsck which could cause pass1b/c/d processing to get
-confused if an attempt to allocate a block can't find any free space
-in the file system.
-
-E2fsck will no longer try to force rewrite blocks located beyond the
-file system.
-
-The e2fsck program will no longer update the quota inodes when it is
-interrupted.
-
-Fix a bug which in rare cases would cause e2fsck -fD to corrupt an
-extent-mapped directory.
-
-Fixed a bug in resize2fs which could lead to resize2fs crashing or a
-corrupted file system if the file system is almost completely full
-when trying grow a file system and we need to allocate blocks to grow
-the block group descriptors.
-
-Fixed a bug in resize2fs which could cause it to get fooled trying to
-determinthe the RAID array's stride when flex_bg is enabled.
-
-Fix resize2fs bug that could leave block allocation bitmaps
-uninitialized.
-
-The dumpe2fs output has been improved so it is cleaner and always fits
-within 80 columns. Also added a more easily machine-parsable output
-of dumpe2fs.
-
-The mke2fs program can now pre-populate a file system from a directory
-hierarchy using the -d option.
-
-The mke2fs program now skips zeroing inode table blocks if they were
-already zeroed using the discard feature.
-
-Check to make sure file system features which can not be supported by
-HURD are not enabled if the file system is created to be
-HURD-compatible.
-
-Added a new e2fuzz command that will fuzz an ext4 image for testing
-purposes.
-
-The debugfs logdump command can now deal with 64-bit revoke tables
-correctly. Also, "logdump -O" will print the old log contents (before
-the journal was replayed).
-
-The debugfs bmap command can now be used to set or allocate a physical
-block.
-
-Fixed a bug so "filefrag -B -e -v" does not return a separate entry
-for each block.
-
-The filefrag program now accounts for holes in sparse files created by
-the file punch operation as an expected/optimal mapping.
-
-The file I/O functions now correctly handle inodes containing
-uninitialized blocks.
-
-Fix a bug in tune2fs so that removing uninit_bg feature on a bigalloc
-file system won't result in corrupted block bitmaps.
-
-Updated/fixed various man pages. (Addresses Debian Bug: #798425)
-
-
-Programmer's Notes
-------------------
-
-Fixed coverity, sparce gcc -Wall, and clang warnings/nits.
-
-Added Android build files so that e2fsprogs can be built in the
-Android source tree.
-
-Reduce the use of libc functions in libext2fs that may not be present
-in the boot loader environment, at least for those functions that are
-needed by boot loadsers such as yaboot.
-
-Developers can now overide the debugging and optimization flags by
-redefining the CFLAGS makefile macro.
-
-The libext2fs library now has support for fallocate.
-
-The mke2fs command will now ask the user for confirmation if block
-device or image file contains an existing file system image, and
-stdout and stdin are connected to a tty.
-
-The libext2fs library now picks a more intelligent goal block when
-doing block allocations.
-
-The libext2fs library will now automatically set the BLOCK_UNINT flag
-if all of the blocks in a block group are free, to speed up future
-e2fsck and dumpe2fs operations on the file system.
-
-Add two new functions ext2fs_new_range() and ext2fs_alloc_range() to
-libext2fs.
-
-The ext2fs_zero_blocks() command will use FALLOC_FL_ZERO_RANGE for
-file-based images.
-
-The ext2fs_bmap() function supports new flags BMAP_UNINIT and
-BMAP_ZERO.
-
-The ext2fs_new_block2() function will now call the alloc_block hook
-before checking fs->block_map.
-
-Support for the MMP feature can now be disabled at compile time.
-
-Added support to manipulate extended attributes to libext2fs.
-
-Added a lot of new regression tests.
-
-Added endian annotations so it's possible to scan e2fsprogs for endian
-problems using a static code analyzer.
-
-Fixed memory leaks in libext2fs.
-
-The e2fsck jbd2 handling code has been resynced with the 3.16 kernel.
-There is now a script in the contrib directory which automates most of
-the resync process.
-
-The build system will now run cppcheck (a static code analysis tool)
-via "make C=1"
-
-
-E2fsprogs 1.42.13 (May 17, 2015)
-================================
-
-Fixed a potential buffer overflow while closing a file system in
-libext2fs. (CVE-2015-1572, Addresses Debian Bug: #778948)
-
-Fixed a bug which could cause e2fsck to corrupt Hurd file systems.
-(Addresses Debian Bug: #760275)
-
-Fixed a deadlock which occurs when using systemd and e2fsck.conf's
-logging feature. (Addresses Debian Bug: #775234)
-
-Fixed a bug which could cause programs using libext2's inode table
-scanning functions from crashing on certain corrupted file systems.
-(Addresses Debian Bug: #773795)
-
-Fixed dumpe2fs so it won't crash if the user doesn't specify a block
-device (file system). (Addresses Debian Bug: #764293)
-
-Fixed e2fsck so if it notices unexpected HTREE blocks in pass 2, it
-will report the correct directory inode containing the inconsistency.
-
-If e2fsck fails to grow the dir_info structure due realloc(3) not
-having enough memory, it will now fail with explanatory message
-instead of staggering on failing with a confusing internal error
-messages.
-
-The tune2fs program will zero out the superblock journal backup
-information when removing a journal from a file system.
-
-The mke2fs program now enables the large_file feature by default.
-
-Fixed a bug which could cause badblocks to crash if there are millions
-and millions of bad blocks.
-
-Fixed some use-after-free bug in resize2fs and e2fsck.
-
-Fixed a memory leak in tune2fs.
-
-Fixed some bigendian bugs that had crept into both indirect and extent
-handling inside libext2fs.
-
-Updated/fixed various man pages.
-
-Update Esperanto, German, and Spanish translations. Added Danish
-translation.
-
-Programmer's Notes
-------------------
-
-Fixed coverity, sparce gcc -Wall, and clang warnings/nits.
-
-Clean up some build system problems (build failures with various
-configure options, fix Posix portability issues, etc.)
-
-The functions ext2fs_inode_alloc_stats[2]() and
-ext2fs_block_alloc_stats[2]() now check the inode and block numbers
-passed to them, to avoid crashes caused by buggy callers.
-
-The libext2fs directory iterator will now check for an invalid
-directory entry length instead of possibly walking off the end of the
-directory buffer.
-
-
-E2fsprogs 1.42.12 (August 25, 2014)
-===================================
-
-Fix various e2fsck bugs when trying to repair bigalloc file systems.
-
-E2fsck can now repair a file system with an overly large
-s_first_meta_bg field, which had previously caused all e2fsprogs
-programs to crash when trying to open such a file system.
-
-Fix e2fsck so that it can correctly fix a number of rare file system
-corruptions that were discovered when using a file system fuzzer.
-
-Fix e2fsck so it does not try to write back block group descriptors if
-they have not been modified.
-
-Mke2fs program will now place metadata blocks in the last flex_bg so
-they are contiguous. This reduces free space fragmentation in a
-freshly created file system, as well as allowing mke2fs commands which
-request extremely large flex_bg size to succeed.
-
-Mke2fs now creates hugefiles more efficiently (with fewer extent tree
-blocks).
-
-Fix a 32/64-bit overflow bug that could cause resize2fs to loop
-forever. (Addresses-Launchpad-Bug: #1321958)
-
-The resize2fs program will now use much less memory when resizing very
-large file systems.
-
-Fix a bug which could cause resize2fs to get confused and produce a
-corrupted file system when shrinking a file system that had been
-previously expanded and converted to use the meta_bg file system
-format, but which no longer needs to use the meta_bg file system
-format any longer. This typically happened with large (> 16TB) file
-systems. (Addresses Debian Bug: #756922)
-
-The e4defrag program will now defrag backwards-allocated files.
-
-Fix tune2fs updating UUID's when manipulating file systems with
-external journals (both the file system and journal UUID).
-
-Fix tune2fs so it can remove an external journal for file systems with
-a 1k block size.
-
-Add a new debugfs command, "inode_dump", which prints the inode in hex
-and ASCII format.
-
-The debugfs's "set_inode_field" will now automatically allocate blocks
-for indirect blocks and extent tree blocks.
-
-Fix debugfs's "set_inode_field" so can properly handle
-"block[IND|DIND|TIND]".
-
-The debugfs "rdump" command will now take multiple source arguments.
-
-Fixed a double close(2) bug in "rdump" and "rdump -p".
-
-Fix debugfs's argument parsing for the freefrag command.
-
-Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
-(Addresses Launchpad Bug: #1356496)
-
-Clarified messages that were confusing users in debugfs, e2fsck,
-mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543,
-#757544)
-
-Dumpe2fs will now complain if extra arguments are given to it.
-(Addresses Debian Bug: #758074)
-
-Updated/fixed various man pages. (Addresses-Debian-Bug: #726760)
-
-Update Czech, Dutch, French, Polish, Spanish, Sweedish, Ukrainian, and
-Vietnamese translations.
-
-Programmer's Notes
-------------------
-
-The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the
-number of system calls issued.
-
-Fixed profiled build.
-
-The libext2fs library will now more efficiently split an extent tree
-index block when appending to an end of a file.
-
-Fixed free block accounting for 64-bit file systems.
-
-Add a new function ext2s_inode_size_set() which takes care of all of
-the required feature flag modifications.
-
-The regression tests no longer require the presence of the md5sum
-program.
-
-Fix build failure on MIPS platforms on Debian (Addresses Debian Bug:
-#754605)
-
-Fix various Coverity warnings (#1225003, #1229243, #1252003)
-
-
-E2fsprogs 1.42.11 (July 9, 2014)
-================================
-
-Add support so that mke2fs can create hugefiles so that they are
-aligned relative to the beginning of the disk, instead of relative to
-the beginning of the partition, using the mke2fs.conf configuration
-parameter "hugefiles_align_disk".
-
-Fix a bug which causes e2fsck to abort a journal replay on a file
-system with bigalloc enabled. (Addresses Debian Bug: #744953)
-
-Add sanity checks so that mke2fs will refuse insanely large flex_bg
-counts specified by the -G option. Insanely large flex_bg sizes can
-result in a file system which can't be unmounted, or with extremely
-pessimal metadata layouts.
-
-The mke2fs program will provide a better metadata layout for
-moderately large (but believable) flex_bg counts, such as 133,072.
-
-The mke2fs progam will also check the kernel version number to
-determine whether the lazy_itable_init option is supported, so that
-lazy inode table initialization can be used even if the ext4 is
-compiled as a module which isn't loaded at the time that mke2fs is
-run.
-
-Add description of ext4's mount options to the ext4 section 5 man
-page.
-
-Improve the chattr man page and clean up the chattr usage message.
-
-E2fsck will now automatically fix a last mount time or last write time
-which is in the future in preen mode, instead of aborting the fsck
-check.
-
-Mke2fs will now check the file system revision number requested by the
-command line, and reject it if it is too large. A file system with an
-unsupported revision number will not be accepted by any of the other
-file system tools, and this command line option is rarely used, so
-let's try to help the user not shoot their own foot off.
-
-The debugfs progam can now set the error count and associated
-first_error and last_error fields in the superblock using the
-set_super_value command.
-
-Resize2fs will not try to calculate the minimum size of a file system
-if it contains errors. Otherwise a very badly corrupted file system
-image can cause the minimum size calculation to loop forwever. Since
-resize2fs will not allow a file system marked as containing errors to
-be resized. It's pointless to calculate the minimum size, so just
-skip it.
-
-Fixed a typo in one of mke2fs's error message.
-
-If filefrag runs into an error, it will continue processing the rest
-of the files specified on thec ommand line, but then exit with an
-error code.
-
-Filefrag now prints some additional new flags (such as
-FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values.
-
-Fixed support in filefrag for files with > 2**32 blocks on 32-bit
-platforms.
-
-Fixed a file descriptor leak in debugfs when copying files.
-
-Fixed a regression introduced in 1.42.10 which caused mke2fs to fail
-to create file systems larger than 2GB on 32-bit platforms.
-(Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107)
-
-Add Esparanto and Ukrainian translations, and update Czech, Dutch,
-French, German, Italian, Polish, Sweedish, and Vietnamese
-translations.
-
-Fixed various compiler warnings.
-
-
-Programmer's Notes
-------------------
-
-The gcc "-checker" option has been long deprecated, so remove support
-from e2fsprogs. It was causing a few people to be confused when they
-tried enabling the configure option.
-
-Update to the latest version of the config.status and config.rpath
-files, as well as newer versions of the autoconf files in aclocal.m4.
-Also, move the e2fsprogs-specific macros to acinclude.m4, which allows
-people who want to use autoreconf to do so.
-
-Make the use of strptime() function in debugfs to be more portable to
-fix regression test failures for FreeBSD and MacOS.
-
-A few miscellaneous changes designed to make life easier for
-translators.
-
-Fix the f_quota test and some Makefile dependencies if quota support
-is not enabled.
-
-Fix cross-compilation support, which got broken in 1.42.10.
-(Addresses Debian Bug: #753375)
-
-Delete lib/ext2_types.h on a make clean, and build it as necessary.
-
-Add a debug program used for libext2fs unit tests.
-
-Clean up the tests so that it avoids using GNU-specific behaviour in
-mktemp. Make sure the temporary files are cleaned up if the tests are
-interrupted.
-
-Add a new ext2fs_close_free() helper function which automatically
-takes care of freeing the ext2_filsys structure even if ext2fs_close()
-returns an error.
-
-
-E2fsprogs 1.42.10 (May 18, 2014)
-================================
-
-Mke2fs now creates file systems in regular files (which is very often
-used when maintaining virtual machine images) without requiring the
-user to use the force option. In addition, the mke2fs output has been
-made much less verbose and only displays information that users will
-be more likely to find useful by default.
-
-Mke2fs now will ask the user to confirm that they want to continue
-before wiping out a pre-existing file system, partition table, or LVM
-physical volume.
-
-Mke2fs now has the ability to create file systems where all the
-metadata is located at the very beginning of the device. This can be
-useful for flash devices which have SLC flash at the beginning of the
-disk, for FAT compatibility, for example. As part of this, mke2fs and
-tune2fs can control the location of the data blocks used by the
-journal inode. In addition, the new sparse_super2 feature allows for
-even fewer (anywhere from zero to two) backup superblocks.
-
-Mke2fs now uses much less CPU when allocating the blocks used for very
-large file systems.
-
-Mke2fs can now support creating a file system at an offset. This can
-be useful when creating a disk image for virtual machines (Addresses
-Debian Bug: #497984)
-
-Previously, e2fsck had a number of very serious bugs when checking a
-file system wich used the new the quota file system option (where the
-quota inodes were stored in hidden inodes) and the quota inode was
-inconsistent with the actual usage data. This problem was documented
-in https://ext4.wiki.kernel.org/index.php/Quota. These problems have
-been fixed in 1.42.10, so the quota should be safe to use with
-e2fsprogs 1.42.10.
-
-Fixed in a bug in resize2fs which could cause shrink operation fail in
-the unlikely situation when the inode table needs to be moved to a
-location before the current location.
-
-Resize2fs now has a much more accurate (and less conservative)
-estimation of how far the file system can be shrunk. This allows a
-mostly empty filesystem which is a few terabytes, to be shrunk to a
-few megabytes in a single resize2fs -M operation.
-
-E2fsck will now force a full file system check if there are any file
-system inconsistencies detected in the super block.
-
-The filefrag program will now display hte shared extent flag, which is
-used by file systems such as btrfs.
-
-If the number of inodes in the file systems is larger than the time
-that file sytem was created (as measured by the number of seconds
-since January 1, 1970) e2fsck would print a scary (but otherwise
-harmless) warning of file system corruption for each inode in the
-orphan list. This false positive has been fixed.
-
-The e4defrag program has been fixed so it will no longer refuse with
-filesystem with the 64-bit or the bigalloc feature enabled.
-
-The logsave progam will print a much less scary message which could
-lead users to believe something has gone very wrong with e2fsck exits
-with a non-zero exit status (since this is normal after e2fsck has
-automatically fixed a file system corruption during a preen
-operation). (Addresses Debian Bug: #468821)
-
-When creating a file system which is larger than 16TB, the
-resize_inode option must be disabled -- since the resize_inode simply
-doesn't support reserving metadata block numbers which is larger than
-32 bits. The mke2fs program does this automatically if the file
-system size is determined automatically. It will now also do this if
-the file size is specified explicitly.
-
-Fixed bugs associated with resize2fs and shrinking bigalloc file
-systems.
-
-The e2fsck program will no longer try to add a UUID on a mounted file
-system with checksums enabled, since this could leave the file system
-checksums broken.
-
-Tune2fs will allow the removal of an external journal from file system
-which is marked as needing the journal replayed when the force ("-f")
-option is given twice. (Addresses Debian Bug: #559301)
-
-Tune2fs will no longer support enabling sparse_super if the meta_bg
-file system feature is enabled, since it could result in data loss.
-In practice, all modern file systems have sparse_super is enabled, so
-it's not worth trying to change how tune2fs handles enabling the
-sparse_super feature.
-
-Fixed support for 1k block file systems with the meta_bg feature.
-
-When the superblock is corrupt, e2fsck can't figure out the location
-of the alternate superblock. Unfortunately, the routine that
-calculates the location of the alternate superblock uses 8193 if it
-can't figure this out, so the message printed by e2fsck always
-suggests using "e2fsck -b 8193". This message has been fixed to
-suggest both the superblock location of 8193 and and 32768.
-(Addresses Debian Bug: #719185)
-
-The lookback mount detection code that was introduced in 1.42.9 wasn't
-actually compiled in due to an autoconf oops, so it's fixed now in
-1.42.10. (Addresses Debian Bug: #497984)
-
-A bug introduced in 1.42.9 would cause debugfs to print two error
-messages if it found an error while parsing a user-supplied block
-number. This has been fixed in 1.42.10.
-
-Update Czech, Dutch, French, German, Polish, Spanish, Sweedish, and
-Vietnamese translations. (Addresses Debian Bug: #703048)
-
-Updated/fixed various man pages. (Addresses Debian Bugs: #719189,
-#719184)
-
-Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725)
-
-
-Programmer's Notes
-------------------
-
-Fixed a lot of coverity, sparce gcc -Wall, and clang warnings/nits.
-
-Allow the location of pkg-config files to be specified independent of
-the libdir location via a makefile variable.
-
-Fixed parse-types.sh not to complain when cross-compiling and the
-sizes of types are different between the target architecture and the
-architecture of the build system
-
-Allow the regression test suite to work correctly on systems which do
-not have the "truncate" or "mksawp" programs.
-
-Allow e2fsck to build correctly on systems (such as Android) that do
-not have the signal.h file.
-
-E2fsprogs now has code coverage testing which can be enbled using
-"configure --enable-gcov".
-
-The libe2p.h header file can now be used included by C++ programs.
-
-The profile/config file used by e2fsck and mke2fs will interpret
-numbers with a leading 0 character to mean that they should be
-interpreted as an octal integer.
-
-The extent handling functions in libext2fs have been improved so they
-have proper rollback when there is an error splitting an extent. Also
-fix a number of bugs when punching holes in files, and fix an
-off-by-one bug when inserting an extent into an empty inode.
-
-The libext2fs library now handles the support of BLOCK_UNINIT by
-clearing the portion of block bitmap when it is loaded, instead of
-when it is used. This reduces the chances of bugs, and and simplifies
-the code. It also means that debugfs will properly show that blocks
-in uninitialized block groups as being unused when using the testb
-command.
-
-The e4defrag program will try to use fadvise64 or posix_fadvise64() if
-it is present, which allows 64-bit offsets on 32-bit systems.
-
-
-E2fsprogs 1.42.9 (December 28, 2013)
-====================================
-
-Mke2fs will detect an attempt to create a file system on a loop
-mounted file and complain without the -FF option. Also fixed mke2fs
-so it allows the creation of a file system on a mounted device with
-two -F options, as documented in the man page, instead of three -F
-options.
-
-Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
-libext2fs to correctly handle bigalloc and 64-bit file systems. There
-were many corner cases that had not been noticed in previous uses of
-these file systems, since they are not as common. Some of the bugs
-could cause file system corruption or data loss, so users of 64-bit or
-bigalloc file systems are strongly urged to upgrade to e2fsprogs
-1.42.9.
-
-The tune2fs program will now not allow changing the uuid on a mounted
-file system which has the uninit_bg feature enabled. This avoids a
-nasty race where the kernel and tune2fs are both retrying rewrite the
-group descriptors at the same time, with different ideas about what
-the UUID should be.
-
-When e2fsck is rehashing an extent-mapped directory, it's possible
-(although very rare) that an extent block will need to be allocated;
-fix e2fsck to make sure that the block gets marked as used.
-
-Mke2fs will now properly set the LARGE_FILE feature when creating a
-journal >= 2GB --- which can happen when using 64k block size.
-
-Fixed debugfs so that its freei command will correctly handle a request
-to free a range of consecutive inodes.
-
-Fixed 2fsck so it will not erroneously complain that an external journal
-is invalid if it is exactly 2**32 blocks.
-
-Fixed e2fsck so it won't try checking for, and adding, a missing
-lost+found directory when running in read-only mode.
-
-Fixed e2image to avoid some buffer overruns which would cause it to when
-creating a "standard (non-raw, non-qcow2) image file. Standard
-e2image files are actually very rarely used, so we didn't notice when
-the changes to enable the qcow2 format broke this e2image mode.
-
-Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
-on the resize_inode feature when the meta_bg feature is set, since
-these two features can not be set at the same time.
-
-Fixed tune2fs so that when it disables the quota feature, it updates all
-of the backup superblocks.
-
-Fixed dumpe2fs that would cause it to abort when run using an image file
-when trying to print the journal information (which is not present in
-an e2image created image file).
-
-Fixed a potential integer overflow in e2reefrag.
-(Addresses-Debian-Bug: #718205)
-
-Enhance debugfs so that when copying a sparse file from a native file
-system into the file system image using the "write" command, it will
-create a sparse file into the destination file system.
-
-Enhanced debugfs so it can support a command line which is up to 8k
-long.
-
-E2image will refuse (unless the -f option is specified to force the
-issue) to create a raw or qcow image using a mounted file system,
-unless the -f option is specified to force the issue.
-
-E2image has been optimized for using it to efficiently copy a file
-system by only copying the allocated blocks, by using the options -ra.
-New options (-o and -O) have been added so that a source and
-destination offset can be given. The -p option will print progress
-information so the user will know how far along the copy is going.
-And finally, the new option -c is useful for updating a file system on
-an SSD, by avoiding unnecessary writes. E2image can also shift a file
-system image by doing an in place move.
-
-Fix a regression introduced in 1.42.8 which would cause e2fsck to
-erroneously report uninitialized extents past the EOF (as determined by
-i_size) to be invalid.
-
-Fixed resize2fs so under a corner case when an inode has a complex
-extent tree, it will not corrupt an interior node in the extent tree.
-
-Fixed resize2fs which would sometimes corrupt a file system when
-shrinking a file system to a minimum size using resize2fs -M.
-(Addresses Debian Bug: #660793)
-
-Fixed resize2fs so that it will relocate inode table blocks if this
-becomes necessary when shrinking the file system.
-
-Fixed resize2fs and e2fsck so they will not crash when hit a failure
-while operating on a file system with the MMP feature enabled.
-
-Fixed a bug in debugfs which caused it create an invalid inode when
-trying to write a zero-length file.
-
-E2fsck will no longer crash if it tries to delete an invalid
-extent-mapped symlink.
-
-E2fsck will no longer crash if it comes across an directory which is
-larger than 2GB (which is not allowed in valid file systems).
-
-Fixed debugfs's help texts to fully document all options and otherwise
-be more helpful.
-
-Updated/fixed various man pages. (Addresses Debian Bugs: #586218,
-#669730, #698076)
-
-Fixed various Debian Packaging Issues (#698879, #721365)

-
-Programmer's Notes
-------------------
-
-Fix sparse, gcc -Wall and clang nits.
-
-Update config.{guess,sub} to the latest version
-
-Fixed various memory and file descriptor leaks on various error paths,
-as well as some missing error return checks, which were found using
-Coverity.
-
-Run sparse against source files when building e2fsprogs with 'make
-C=1'. If instead C=2, it configures basic ext2 types for bitwise
-checking with sparse, which can help find the (many many) spots where
-conversion errors are (possibly) happening.
-
-Allow the regression test to be run in chrooted environments where
-/etc/mtab might be missing.
-
-The ext2fs_punch() function, which was introduced in 1.42, was broken
-in many ways, but this was never noticed since it wasn't used for
-anything significant. Some of the bugs include failing when trying to
-punch a completely sparse file, failing when punching an extent-mapped
-inode when the starting block was at the beginning of the inode, and
-not being able to punch a single block (where start_blk == end_block).
-It also didn't handle being passed an invalid, too-large ending block
-number, and didn't handle properly terminate at the right place when
-operating on an indirect-mapped inode.
-
-Fixed some minor typo's in the error catalog for libext2fs.
-
-Fixed ext2fs_file_set_size2() so that if it truncates an inode by
-setting the file size, to zero the rest of the block to the end of the
-file, so that if an ext4 FUSE driver tries to extended the file, that
-we don't avoid stale data from being returned.
-
-Fixed ext2fs_bmap() to disallow clients from trying to map or set
-logical blocks which are larger than what an extent-mapped or indirect
-block-mapped inode can allow.
-
-If debugfs (or some userspace program using libext2fs) creates a file
-which is larger than 2GB, make sure the large_file feature flag gets
-set.
-
-Fix a bug in ext2fs_link() where if there is multiple empty slots in the
-directory which are large enough, the directory entry could get
-inserted more than once in the directory.
-
-If quota support is disabled (which is the default), make sure that
-all traces of the quota support is removed from usage messages, man
-pages, and tune2fs must not be able to enable the quota file system
-feature. (Addresses Red Hat Bugzilla: #1010709)
-
-The ext2fs_file_write() now updates i_size on a successful write,
-instead of only updating i_size wen the file is closed via
-ext2fs_file_close().
-
-Added a shell script, populate-extfs.sh which uses debugfs to populate
-an ext2/3/4 file system image from a given directory. It is similar
-to the genext2fs program, but it supports ext3 and ext4 file system.
-
-Add changes to the libext2fs library to support block group
-descriptors larger than 64 bytes (for future compatibility).
-
-Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
-leave an extra block in the file when truncating the file down to
-size.
-
-The html version info pages are now built using makeinfo --html
-instead of the unmaintained and now-obsolete texi2html program.
-
-
-E2fsprogs 1.42.8 (June 20, 2013)
-================================
-
-As a part of mke2fs's option parsing cleanup, the use of the -R option
-will give a warning that it is depreated (it has been so documented
-since 2005) and -E should be used instead.
-
-Mke2fs will not give warnings about the bigalloc and quota options in
-quiet mode.
-
-If an invalid journal size is given to mke2fs, it will now complain
-and exit sooner.
-
-Debugfs was erroneously giving spurious error messages for certain
-extent_inode subcommands which take arguments (split_node,
-replace_node, and insert_node). This has been fixed.
-
-Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
-other programs is used by mke2fs.
-
-Change mke2fs so that it does not set the root directory to the real
-uid/gid of the mke2fs process. Add the extended option root_owner to
-override this behavior.
-
-Fix resize2fs when shrinking file systems to make sure that bitmap
-blocks aren't left outside the bounds of the shrunken file system.
-This could happen with flex_bg file systems that were grown using
-the old online resizing algorithm.
-
-E2fsck will now detect and repair corrupted extent trees which contain
-invalid extents at the end of the extent tree leaf block.
-
-E2fsck will now longer complain about zero length extended attribute
-values.
-
-Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
-to crash.
-
-Add safety check so tune2fs will not attempt to set the inode size to
-be larger than the block size.
-
-Fix e2fsck so it can check a read-only root file system with an
-external journal. (Addresses Debian Bug: #707030
-
-Fix off-line resizing of file systems with flex_bg && !resize_inode
-(Addresses Debian Bug: #696746)
-
-Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug:
-#703067)
-
-Enhance chattr to allow clearing the extent flag if the kernel allows
-migrating extent based files to use indirect blocks.
-
-Update German translation.
-
-Updated/fixed various man pages. (Addresses Debian Bugs: #712429,
-#712430, #707609)
-
-Fixed various Debian Packaging Issues (Addresses Debian Bug #708307)
-
-Programmer's Notes
-------------------
-
-Use secure_getenv() in preference to __secure_getenv().
-
-Optimize CPU utilization of ext2fs_bg_has_super().
-
-Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
-SEEK_CUR is used with large files.
-
-The ext2fs_read_inode_full() function will no longer use
-fs->read_inode() if the caller has requested more than the base 128
-byte inode structure and the inode size is greater than 128 bytes.
-
-Fix build failure with --enable-jbd-debug.
-
-Clean up filtering of outputs for the regression tests by using a
-common sed script.
-
-Fix gcc -Wall and clang nits.
-
-
-E2fsprogs 1.42.7 (January 21, 2013)
-===================================
-
-Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
-quota features are still under development. For more information
-please see:
- * https://ext4.wiki.kernel.org/index.php/Bigalloc
- * https://ext4.wiki.kernel.org/index.php/Quota
-
-Add some new options to filefrag from Lustre's patches to e2fsprogs:
- * add -k option to print extents in kB-sized units (like df -k)
- * add -b {blocksize} to print extents in blocksize units
- * add -e option to print extent format, even when FIBMAP is used
- * add -X option to print extents in hexadecimal format
-
-Fix resize2fs so that it can handle off-line resizes of file systems
-with the flex_bg feature but without a resize_inode (or if we run out
-of reserved gdt blocks). This also fixes a problem where if the user
-creates a filesystem with a restricted number of reserved gdt blocks,
-an off-line resize which grows the file system could potentially
-result in file system corruption.
-
-Fix a resize2fs bug which could cause it to corrupt bigalloc file
-systems when doing an off-line resize.
-
-Further optimize resize2fs so it doesn't use quite as much CPU when
-resizing very large file systems.
-
-Fixed 32-bit overflow bugs which could cause resize2fs to fail and
-possibly corrupt the file system while resizing 64-bit file systems.
-
-Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
-mke2fs crash due to a divide-by-zero if the 64bit file system feature
-is enabled.
-
-Add better error checking to mke2fs to check for invalid parameters
-when creating bigalloc file system.
-
-When creating bigalloc filesystems, the -g option to mke2fs will now
-specify the number of clusters per block group.
-
-Add to debugfs the functionality to corrupt a specific file system
-block via the "zap_block" command.
-
-Add to debugfs the functionality to print out a hex dump of a block in
-the file system via the "block_dump" command.
-
-Add to debugfs the functionality to manipulate the extent tree
-directly via the "extent_open" command.
-
-Fixed debugfs's mknod command so that it updates the block group
-statistics.
-
-Fix e2fsck so it can detect and fix inconsistencies in the interior
-nodes of an inode's extent tree.
-
-Fix a potential memory corruption failure in e2fsck's error path if
-the call to ext2fs_open2() fails.
-
-Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
-resulting file name for the log file is longer than 100 bytes, that it
-properly handles this situation instead of crashing.
-
-E2fsck will now report the amount of memory that it attempted to
-allocate when a memory allocation request fails, to make it easier to
-track down the problem.
-
-Fix mke2fs's handling of the mmp_update_interval option. (Addresses
-Lustre Bug: LU-1888)
-
-E2image can now include all data blocks in the e2image output file
-when the user specifies the -a option.
-
-If e2fsprogs is compiled without --enable-quota, make sure that
-tune2fs can not turn on the feature for new-style quota support, since
-afterwards, none of the e2fsprogs tools will be willing to touch that
-file system.
-
-Optimize e2fsck's so that it uses much less CPU for large file
-systems. This can result in significant speedups, especially on
-CPU-constrained systems. This was primarily done by optimizing
-libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
-
-Fix debugfs's htree command so that all its messages are sent through
-the pager.
-
-Fixed debugfs's "dump_file" and "cat" functions work correctly
-on file systems whose block size is greater than 8k.
-
-Fix e2freefrag so it works on 64-bit file systems, and so it uses much
-less memory. (Addresses Google Bug: 7269948)
-
-Update the spd_readdir.c file in the contrib directory to include some
-additions which were made in 2008 that didn't get folded into the
-version which we checked into the e2fsprogs source tree. These
-enhancements include thread safety, support for readdir64_r(), and
-safe_getenv() support in case spd_readdir.so is used for setuid binaries.
-
-Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
-translations
-
-Add a command to debugfs to create symlinks.
-
-Document the bigalloc feature in the mke2fs man page. (Addresses
-Debian Bug: #669730)
-
-
-Programmer's Notes
-------------------
-
-Fix gcc -Wall nits.
-
-Fix a spelling typo in the libext2fs texinfo documentation.
-
-Change the output from "make check" so that tools such as emacs's "M-x
-compile" does not mistake the output as containing a compiler error.
-
-Export two new functions from libext2fs: ext2fs_extent_node_split()
-and ext2fs_extent_goto2().
-
-The ext2fs_extents_fix_parents() was fixed so it does not modify the
-location of the extent handle if its current location is at an
-interior node, rather than a leaf node of an inode's extent tree.
-
-Add a regression test to assure that e2fsck can correctly fix an
-inconsistent interior node in an inode's extent tree.
-
-The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
-correctly support bigalloc file systems which use store block usage
-information in units of clusters.
-
-Fixed the help text in the configure script for --enable-quota.
-
-The m68k-specific bitops code has been removed since they were
-incorrectly treating bit numbers with the high bit set as signed
-integers. Furthermore, modern compilers do a good enough job
-optimizing the generic code there is no point in having the m68k
-specific asm statements.
-
-Fixed how we link the test programs so they always use the static
-libraries, so that we test using the libraries which we have just
-built.
-
-Update config.guess and config.sub to the latest versions from the GNU
-project.
-
-Fixed the com_err.texinfo file so that it can produce a valid
-postscript/pdf printed output.
-
-Add a regression test which checks debugfs's ability to create
-symlinks, named FIFO's, and device nodes.
-
-Add a function ext2fs_symlink(), which creates symlinks to the
-libext2fs library.
-
-Add debugging code so we can test old kernel interfaces for online
-resize to resize2fs. This backwards compatibility checking is keyed
-off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
-test the functionality of the kernel's older resize ioctls without
-needing to install an old version of resize2fs, and to also test a
-modern resize2fs's ability to work with older kernels without having
-to install an older version of the kernel.
-
-
-E2fsprogs 1.42.6 (September 21, 2012)
-=====================================
-
-When mke2fs creates file systems with lazy itable initialization, the
-progress updates for writing the inode table happens so quickly that
-on a serial console, the time to write the progress updates can be the
-bottleneck. So mke2fs will now only update its progress indicators
-once a second.
-
-Resize2fs will skip initializing the inode tables if the kernel
-supports lazy_itable_init, which speeds up growing off-line growth of
-uninit_bg file systems significantly. Resize2fs will now also
-correctly set the itable_unused field in the block group descriptor to
-speed up the first e2fsck after the file system is grown.
-
-Resize2fs has been fixed so that on-line resizing of meta_bg file
-systems work correctly. This is needed to grow file system which are
-larger than 16T.
-
-Resize2fs will now correctly handle resizing file systems to 16TB on
-32-bit file systems when "16TB" is specified on the command line.
-
-Fix mke2fs so that it will be careful to set the reserved blocks ratio
-larger than 50%; this can happen when creating small file systems and
-when the last block group is dropped because there are not enough
-blocks to support the metadata blocks in the last block group.
-
-Fixed spelling mistake in debugfs's help message.
-
-Fixed a potential seg fault in e2fsck when there is an I/O error while
-reading the superblock.
-
-Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
-
-Updated/fixed various man pages. (Addresses Sourceforge Bug:
-#3559210)
-
-Programmer's Notes
-------------------
-
-The configure option --enable-relative-symlink was broken so that it
-needed to be --enable-symlink-relative-symlinks. We will support both
-for at least two years, but then the worng configure option will be
-removed.
-
-Fixed a regression introduced in 1.42.5 so the link order for
-e2fsprogs' libraries will be correct for both static and shared
-linking. (Addresses Sourceforge Bug: #3554345)
-
-Add support for e2fsprogs to be compiled using clang/LLVM.
-
-Fix portability problems on non-Linux systems: avoid compile failures
-on systems that don't have malloc.h
-
-Fix f_mmp regression test suite so that debugfs gets killed if the
-test is interrupted.
-
-
-
-E2fsprogs 1.42.5 (July 29, 2012)
-================================
-
-Fixed a bug with mke2fs where if there is only 8 inodes per block
-group, the calculation of the number of uninitialized inodes in the
-first block group would go negative. This resulted in "mke2fs -N 256
--t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
-would run out of space. (Addresses Sourceforge Bug: #3528892)
-
-Fixed a bug in how e2fsck would uniquify directory entry names.
-(AddressesSourceforge Bug: #3540545)
-
-Previously, e2fsck would only allow a mounted file system to be
-checked if it was the root file system and it was mounted read-only.
-Now it will allow any file system mounted read-only to be checked if
-the -f option is specified. This makes it easier to test how e2fsck
-handles checking file systems which are mounted without having to test
-on the root file system.
-
-Fixed a problem if e2fsck where if the root file system is mounted
-read-only, e2fsck would not clear an error indication in the journal
-superblock. Combined with a kernel bug, this would cause the e2fsck
-to check the file system after every single boot.
-
-The e4defrag program can now handle device symlinks, such as
-/dev/mapper/testvg-testlv, instead of insisting on a less
-human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
-#707209)
-
-Fixed filefrag so it will not crash with a segfault on files from a
-virtual file system such as /proc. (e.g., "filefrag
-/proc/partitions")
-
-Fixed filefrag so that it correctly reports the number of extents.
-(Addresses Red Hat Bugzilla: #840848)
-
-Fixed a file descriptor leak in logsave which could cause it to hang.
-(Addresses Debian Bug: #682592)
-
-Fixed e2fsck so that the file system is marked as containing an error
-if the user chooses not to fix the quota usage information.
-
-Fixed tune2fs so that it correctly removes the quota feature when the
-last quota inode is removed.
-
-Fix tune2fs so that after removing a quota inode, the block bitmap is
-updated; otherwise, e2fsck would complain after running 'tune2fs -O
-^quota <dev>'.
-
-Fix tune2fs so that when converting a file system from using legacy
-quota files to the new quota file system feature with hidden quota
-files, the accounting for these files is handled correctly so that
-e2fsck doesn't complain.
-
-Improved e2fsck's verbose reporting statistics, and allow the more
-verbose reporting to be enabled via /etc/e2fsck.conf.
-
-Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
-
-Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
-
-
-Programmer's Notes
-------------------
-
-Fixed portability problems on other operating systems (e.g., Hurd and
-FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
-
-Make sure that shared libraries link with the shared libraries built
-in the build tree, instead of the system provided libraries.
-Previously, libraries and executables were linked with the system
-libraries if present, and possibly using static archives instead of
-shared libraries. This was also problematic since if libext2fs.so is
-linked with a static libcom_err.a from system, the build system would
-attempt to link without -lpthread. (Addresses Sourceforge Bug:
-#3542572)
-
-
-E2fsprogs 1.42.4 (June 12, 2012)
-================================
-
-Fixed more 64-bit block number bugs (which could end up corrupting
-file systems!) in e2fsck, debugfs, and libext2fs.
-
-Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
-not properly propagating the journal's s_errno field to the superblock
-field; it was not checking this field if the journal had already been
-replayed, and if the journal *was* being replayed, the "error bit"
-wasn't getting flushed out to disk.
-
-Fixed a false positive complaint by e2fsck if all of the extents in
-the last extent tree block are uninitalized and located after the end
-of the file as defined by i_size.
-
-The dumpe2fs will now display the journal's s_errno field if it is
-non-zero, and it will also display the journal's 64-bit feature flag
-if present.
-
-Fix e2fsck so that it always opens the device file in exclusive mode
-when it might need to modify the file system, and never if the -n
-option is specified. (Previously, there were a few corner cases where
-it might get things wrong in either direction.)
-
-E2fsck now correctly truncates or deallocates extent-mapped inodes on
-the orphan list. The root cause was a bug in libext2fs's block
-iterator which could end up skipping an extent when the last block in
-an extent is removed, causing the current extent to be removed from
-the extent tree.
-
-E2fsck now correctly sets the global free block and inode counts when
-truncating or removing inodes on the orphan list in preen mode.
-Previously, it would leave these values would be set incorrectly,
-which is largely a cosmetic issue since the kernel no longer pays
-attention to those fields, but it can cause spurious complaints in
-subsequent e2fsck runs.
-
-Fix i_blocks accounting when the libext2fs library needs to add or
-remove an extent tree block on bigalloc file systems.
-
-The lsattr and chattr programs now support the No_COW flag for the
-benefit of btrfs.
-
-Debugfs now interprets date strings of the form @ddd as ddd seconds
-after the beginning of the epoch. This is handy when setting an inode
-number into the d_time field when debugging orphan list handling.
-
-Fix a precedence bug with built-in quota support which might result in
-e2fsck paying attention to the quota inode field even if the built-in
-quota feature flag is not set. Fortunately, in practice that
-superblock field should be zero for non-built-in quota file systems,
-so it's unlikely this bug would have caused problems.
-
-Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
-#674694)
-
-Programmer's Notes
-------------------
-
-The regression test suite can now run the integration tests in the
-tests directory in parallel, via "make -jN check".
-
-Add new test, f_zero_extent_length which tests e2fsck's handling of
-the case where all of the extents in the last extent tree block are
-uninitialized extents after i_size.
-
-Add a new test, f_jnl_errno, which checks handling of an error
-indication set in the journal superblock.
-
-Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
-of a 64-bit journal.
-
-Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
-tests e2fsck's handling of orphan inodes in preen mode, and truncation
-of extent inodes on the orphan list.
-
-Fixed more OS X portability issues.
-
-
-E2fsprogs 1.42.3 (May 14, 2012)
-===============================
-
-Fix a bug in the Unix I/O manager which could cause corruption of file
-systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
-(i.e., when unsigned long is 32-bits). Also fix a bug which caused
-dumpe2fs to incorrectly display block numbers > 32-bits.
-
-Improve the support for integrated quota files (where quota is a first
-class supported feature using hidden files in the ext4 file system).
-Previously the quota file was getting rewritten even when it was not
-necessary, and e2fsck would erroneously try to hide quota files which
-were already hidden.
-
-Quiet complaints in e2fsck when the total free blocks or inodes are
-incorrect in the superblock after an system crash, since we don't
-update nor depend on the superblock summaries at each commit boundary.
-
-Fixed a regression introduced in 1.42.2 which would cause applications
-outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
-would were still using the legacy 32-bit bitmaps) to crash. This was
-due to missing 32-bit compat code in side the function
-ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
-#808421)
-
-Fix a bug which would cause mke2fs to fail creating the journal if
-/etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
-#3509398)
-
-Updated/fixed various man pages.
-
-Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
-translations
-
-Fixed various Debian Packaging issues.
-
-
-Programmer's Notes
-------------------
-
-Change the nonsensically wrong types in the function signature of the
-inline function ext2fs_find_first_zero_block_bitmap2(). This was
-caused by a cut and paste error; fortunately no code in e2fsprogs used
-this inline function, and there are any users of this functions
-outside of e2fsprogs.
-
-Add support for systems which have valloc(), but which do have
-posix_memalign() nor memalign() (such as MacOS 10.5).
-
-Refactor and clean up the allocation of aligned buffers for Direct I/O
-support. Previously some allocations were requesting a greater
-alignment factor that what was strictly necessary. Also optimize
-reading and writing bitmaps using Direct I/O when the size of the
-bitmap did not fully cover the file system blocksize.
-
-Reserve the codepoints for the INCOMPAT features LARGEDATA and
-INLINEDATA.
-
-Improved the regression test suite by adding some new integration
-tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
-jbd2 format, as well as f_eofblocks which tests the new handling of
-uninitialized and initialized blocks beyond i_size. Also add a new
-unit test which verifies 32-bit bitmaps support and the new
-find_first_zero primitives.
-
-Add a few dependencies to fix parallel (make -j) builds.
-
-Removed bash'isms which were breaking the regression test suite on
-systems where /bin/sh is not bash.
-
-The config.guess and config.sub have been updated to the 2012-02-10
-version.
-
-Fix a portability problem caused by assuming the present of mntent.h
-means that setmntent() exists. Instead, explicitly test for this in
-the configure script.
-
-If the sys/signal.h header file does not exist, don't try to include
-it, since it's not available on all systems.
-
-Add support for systems that do not support getpwuid_r()
-
-The configure script now supports a new option,
---enable-relative-symlinks, which will install relative symlinks for
-the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
-
-When building BSD shared libraries make sure the LDFLAGS variable is
-passed to the linker. Fixing this allows, for example, e2fsprogs to
-be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
-#3517272)
-
-Fix gcc -Wall nitpicks
-
-
-E2fsprogs 1.42.2 (March 27, 2012)
-=================================
-
-The resize2fs program uses much less CPU and is much faster for very
-large file systems. (Addresses Debian Bug: #663237)
-
-The seti and freei commands in debugfs can now take an optional length
-argument to set and clear a contiguous range of inodes.
-
-E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
-plan to remove support for it from the kernel file system driver. It
-really wasn't very useful and was causing more problems than it
-solves. Since e2fsck will complain if inodes that should have
-EOFBLOCKS_FL do not have the flag set, we are going to remove this
-check from e2fsprogs first, and then only remove the flag from the
-kernel much later.
-
-The mke2fs program can now use direct I/O via "mke2fs -D". This will
-slow down the mke2fs, but it makes it more polite on a loaded server
-by limiting the amount of memory that gets dirtied by mke2fs when it
-is using buffered I/O.
-
-E2fsck was needlessly closing and re-opening the file system as a side
-effect of adding Multiple Mount Protection (MMP). This isn't
-necessary for non-MMP file systems, so drop it.
-
-Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
-can more easily diagnose memory allocation failures caused by
-insufficient memory. E2fsck will now abort if there are memory
-allocation failures when the file system is initially opened and
-during the block group descriptor checks. (Addresses Google Bug:
-#6208183)
-
-If there are incorrect block group checks, e2fsck will now report the
-incorrect and corrected checksum values.
-
-The e2fsck progam can now write log files containing the details of
-the problems that were found and fixed directly, via configuration
-parameters in /etc/e2fsck.conf.
-
-Added the ability to limit the number of messages reported by e2fsck
-for a given problem type. This avoids a potential bottleneck if there
-is a serial console which can cause a boot sequence to take a long
-time if e2fsck needs to report many, many file system errors.
-
-The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
-them to use much less memory for large file systems.
-
-The dumpe2fs program will now print the expected block group checksum
-if it is incorrect. This helps to diagnose problems caused by
-incorrect block group checksums.
-
-E2fsck now checks for extents with a zero length, since the kernel
-will oops if it comes accross such a corrupted data structure. (See
-https://bugzilla.kernel.org/show_bug.cgi?id=42859)
-
-E2fsck has a number of bugs relating to discard that have been fixed.
-(1) Fixed a bug which could cause e2fsck to discard portions of the
-inode table which were actually in use. (2) E2fsck will now avoid
-using discard if the block device doesn't zero data on discard, since
-otherwise this could cause problems if the file system gets corrupted
-in the future. (3) E2fsck will now avoid using discard when it is run
-in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
-discards in the last block group.
-
-E2fsck's CPU utilization in pass 5 has been optimized, which will
-speed up e2fsck slightly.
-
-E2image will now skip copying uninitialized bitmap and inode table
-blocks.
-
-Fixed mke2fs -S so it does not corrupt the first block group's
-information.
-
-E2fsck will now check the new sysfs interface to determine if we are
-using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
-
-Updated/fixed various man pages. (Addresses Debian Bug: #665427)
-
-Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
-
-Programmer's Notes
-------------------
-
-Fixed various portability issues for non-Linux systems, particularly
-MacOS X, as well as Linux systems running with the just-released glibc
-2.15.
-
-Fix file descriptor leak in ext2fs_close() if the file system with
-uninit_bg is opened read/only with a backup superblock. (Addresses
-SourceForge Bug: #3444351)
-
-Fixed an invalid return in a non-void function in the quota code.
-(Addresses SourceForge Bug: #3468423)
-
-Fixed the debian rules file so that the calls to dpkg-buildflags works
-when the shell is dash.
-
-The debian package build now uses V=1 so that there is more
-information about potential build failures in debian buildd logs.
-
-If the uninit flags get cleared by functions such as
-ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
-superblock is marked dirty and the block group descriptor checksum is
-updated if necessary.
-
-The debian rules file will now try to load debian/rules.custom of it
-exists. This flie can skip various builds for speed reasons if there
-is no need for the e2fsck-static or udeb packages. Available
-customizations in the rules file includes SKIP_STATIC=yes,
-SKIP_BF=yes, and SKIP_DIETLIBC=yes.
-
-In addition, if the file misc/mke2fs.conf.custom.in exists in the
-source tree, it will be used instead of the standard misc.conf file in
-the upstream sources. This makes it easier for Debian-derived systems
-to distribute a custom mke2fs.conf file without having to worry about
-merge issues if future versions of e2fsprogs makes changes in the
-upstream default version of mke2fs.conf.
-
-
-E2fsprogs 1.42.1 (February 17, 2012)
-===================================
-
-The mke2fs and e2fsck now use significantly less memory when creating
-or checking very large file systems. This was enabled by adding
-extent-based bitmaps which are stored using a red-block tree, since
-block and inode allocations tend to be contiguous.
-
-The command mke2fs -S is used as a last ditch recovery command to
-write new superblock and block group descriptors, but _not_ to destroy
-the inode table in hopes of recovering from a badly corrupted file
-system. So if the uninit_bg feature is enabled, mke2fs -S will now
-set the unused inodes count field to zero. Otherwise, e2fsck -fy
-after using mke2fs -S would leave the file system completely empty.
-
-Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
-honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
-installed an mke2fs binary using that name.
-
-The usage and help messages for the -G, -t and -T options in mke2fs
-have been fixed.
-
-If e2fsck needs to use the backup group descriptors, the
-ext2fs_open2() function clears the UNINIT bits to ensure all of the
-inodes in the file systems get scanned. However, the code which reset
-the UNINIT flags did not also recalculate the checksum, which produced
-many spurious (and scary) e2fsck messages. This has been fixed by
-resetting cheksums when the UNINIT bits are cleared.
-
-Relax a check in e2fsck which required that the block bitmap to be
-initialized when the inode bitmap is in use. This will allow us to
-eventually eliminate code from the kernel which forcibly initialized
-the block bitmap when the inode bitmap is first used, requiring an
-extra journal credit and disk write. (Addresses Google Bug: #5944440)
-
-Make sure rdebugfs (which may be installed setuid or setgid disk) does
-not honor environment variables if euid != uid or egid != gid.
-
-Debugfs's ncheck command has been optimized and now is much more
-robust with faced with corrupted file systems. The ncheck command
-also now has a -c option which will verify the file type information
-in the directory entry to see if matches the inode's mode bits. This
-is extremely useful when trying to use debugsfs to determine which
-parts of the file system metadata can be trusted.
-
-E2image will try to use ftruncate64() to set the i_size for raw
-images, instead of writing a single null byte. This avoid allocating
-an extra block to the raw image, for those file systems and/or
-operating systems that support this. (Linux does.) In addition, fix
-a logic bug that caused the file to not be properly extended if the
-size of the last hole was exactly an multiple of a megabyte.
-
-Fixed a bug in resize2fs where for 1k and 2k file systems, where
-s_first_data_block is non-zero, this wasn't taken into account when
-calculate the minimum file system size for use with the -M option.
-
-Fixed the badblocks program to honor the -s flag when in read-only -t
-mode. (Addresses Debian Bug #646629)
-
-Update Czech, Dutch, French, Polish, and Sweedish translation from the
-Translation Project.
-
-Fixed various Debian Packaging issues so that dpkg-buildflags is used
-if present, which allows e2fsprogs to be built with security hardening
-flags. (Addresses Debian Bugs: #654457)
-
-Programmer's Notes
-------------------
-
-Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
-This was only an issue for programs compiled against e2fsprogs 1.41
-that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
-#3451486)
-
-The libext2fs library now uses sysconf() to fetch the page size, instead
-of the deprecated getpagesize().
-
-The ext2fs_get_pathname() function will return a partial path if an a
-directory in the path is not a directory, displaying it as an inode
-number in angle brackets instead of giving up and displaying an error.
-This is much more helpful when a user is trying to debug a corrupted
-file system.
-
-Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
-
-Added a new library function, ext2fs_file_get_inode_num(), for use by
-fuse2fs.
-
-Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
-file, it actually works.
-
-The block iterator now properly honors the BLOCK_ABORT flag for
-extent-based flags. Previously, it didn't, which generally made code
-be less efficient, but it could cause bugs in ext2fs_link(), for
-example, by causing it to insert multiple directory entries.
-
-Fixed an (harmless other than causing a compiler warning) use of an
-uninitialized variable in e2fsck's MMP code.
-
-
-E2fsprogs 1.42 (November 29, 2011)
-==================================
-
-This release of e2fsprogs has support for file systems > 16TB. Online
-resize requires kernel support which will hopefully be in Linux
-version 3.2. Offline support is not yet available for > 16TB file
-systems, but will be coming.
-
-This release of e2fsprogs has support for clustered allocation. This
-reduces the number of block (now cluster) bitmaps by allocating and
-deallocating space in contiguous power-of-2 collections of blocks,
-which are called clustered. This is a file system level feature,
-called 'bigalloc', which must be enabled when the file system is
-initially formatted. It is not backwards compatible with older
-kernels.
-
-Added support for the Multi-Mount Protection (MMP) feature.
-
-E2fsck more efficiently uses scratch files for really big file
-systems. (This is a feature that has to be turned on explicitly; see
-[scratch_files] in the e2fsck.conf man page.)
-
-Fix a bug in e2fsck where if the free blocks and inodes counts are
-incorrect, e2fsck would fix them without printing an error message.
-This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
-any explanation of what was fixed.
-
-E2fsck will no longer attempt to clone an extended attribute block in
-pass1b handling if the file system does not support extended
-attributes.
-
-E2fsck will be more careful accidentally asking the user to continue
-if the file system is mounted, so that an escape sequence won't cause
-a false positive. (Addresses Debian Bug: #619859)
-
-E2fsck now uses less cpu time in pass 5 when large portions of the
-bitmaps are uninitialized.
-
-E2fsck will no longer segault when a corrupted file system has a bad
-extent, and removing it leads to a block needing to be deallocated.
-(Addresses SourceForge Bug: #2971800)
-
-E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
-and print debugging information to make it easier to find potential
-problems.
-
-E2fsck will check to see if the bad block inode looks insane, and will
-skip trying to use if it certain fields which should be zero look
-non-zero. This is to avoid a corrupted bad block inode causing e2fsck
-to get confused and do more harm than good.
-
-If e2fsck modifies certain superblock fields which the kernel doesn't
-look at, it will now mark the superblock as dirty without marking the
-file system as changed. This avoids signalling the init scripts that
-a reboot is necessary, since the kernel isn't going to look at those
-fields, so it won't care if they have been changed.
-
-Fixed a bug in the libext2fs library (in the binary search routine of
-the icount abstraction) that could (very, very rarely) cause e2fsck to
-die in the middle of pass 1 or pass 2 processing.
-
-E2fsck will not try to do a discard operation if the -n option was
-specified on the command line.
-
-E2fsck now supports an extended "discard" option which will cause
-e2fsck to attempt discard all unused blocks after a full, successful
-file system check.
-
-E2fsck will check for the bad block inode to make sure it looks sane
-before trusting it, to avoid causing more harm than good to the file
-system.
-
-E2fsck now returns additional status bits in its exit code if it
-aborts early in the e2fsck run.
-
-E2fsck now correctly calculates the maximum file size in the case of
-the huge_file file system feature enabled without extents.
-
-The mke2fs and e2fsck programs now tries to use the punch hole command
-as a "discard" when operating on normal files.
-
-The e2image program now supports the qcow2 format, which is a more
-efficient way of capturing file system dumps.
-
-Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
-per-device defaults to be specified in the configuration file.
-
-Mke2fs now supports the reserved_ratio relation in the [defaults] and
-[fs_types] section in mke2fs.conf.
-
-Mke2fs now creates extent-mapped directories for the root and
-lost+found directories.
-
-Mke2fs will skip zero'ing the journal if the extended option
-"lazy_journal_init" is specified. This can save a lot of time, but it
-does add a small amount of risk if the system crashes before the
-journal is overwritten entirely once. It is epsecially useful for
-testing.
-
-Mke2fs will now create file systems that enable user namespace
-extended attributes and with time- and mount count-based file
-system checks disabled.
-
-Mke2fs will not set a stride or strip size of one block based on block
-device attributes obtained from sysfs.
-
-Mke2fs now displays a progress report during the discard process.
-
-Mke2fs now handles extreme file system parameters correctly which
-previously caused the inodes per group to drop below 8, leading to a
-segfault. (The inodes per group must be a multiple of 8, but the code
-didn't correctly deal with an inodes per group count less than 8.)
-
-Mke2fs and tune2fs previously would give an error if the user tried
-setting the stride and stripe-width parameters to zero; but this is
-necessary to disable the stride and stripe-width settings. So allow
-setting these superblock fields to zero. (Addresses Google Bug:
-#4988557)
-
-Mke2fs now gives a warning if the auto-detected block size exceeds the
-system's page size.
-
-If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
-is the default), mke2fs will now set the s_max_mnt_count superblock
-field to -1, instead of 0. Kernels older then 3.0 will print a
-spurious message on each mount then they see a s_max_mnt_count set to
-0, which will annoy users. (Addresses Debian Bug: #632637)
-
-The default mke2fs.conf now has entries for "big" and "huge", which
-are needed for very big file systems.
-
-The resize2fs program now has support for a new online resize ioctl
-that can support file systems > 16TB, once it arrives in v3.x kernels.
-
-Fixed bug which caused resize2fs to fail when shrinking an empty file
-system down to its minimal size. (Addresses Sourceforge Bug #3404051)
-
-Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
-
-Allow tune2fs to remove external journals if the device can not be
-found.
-
-Debugfs's icheck will now correctly find inodes which use the
-searched-for block as an extended attribute block.
-
-Debugfs now has a new "punch" command which remove blocks from the
-middle of an inode.
-
-Debugfs now has a new "e2freefrag" command which analyzes the free
-space fragmentation of the file system, using the same code as the
-e2freefrag program.
-
-Debugfs now has a "filefrag" command which displays information about
-a file's fragmentation.
-
-Add support to build a metadata-only, read-only, stripped-down version
-of debugfs called rdebugfs.
-
-Fixed a potential stack overrun bug in debugfs.
-
-The badblocks program now correctly recovers from I/O errors when
-direct I/O is being used. The badblocks command now also supports a
--B option which forces the use of buffered I/O, and the -v option will
-provide a more detailed breakdown of read, write, and failed
-comparison errors.
-
-Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
-
-Added support for journals larger than 2GB.
-
-Support using both hard links and symlinks when installing e2fsprogs.
-
-Add overflow checking to tune2fs -i's fsck interval, which must fit in
-a 32-bit field.
-
-The debugfs command now has a new 'blocks' command which prints out
-data blocks of a particular inode in a format which is useful for
-scripting.
-
-Filefrag will report 0 extents correctly in verbose mode. (Addresses
-RedHat Bugzilla: #653234)
-
-Filefrag has been fixed so its -v report prints the correct expected
-block number (previously there had been an off-by-one error). In
-addition, it will now display the number of contiguous extents when -v
-is not specified. This makes it consistent with the number of extents
-printed when the -v option was specified. In addition, the number of
-contiguous extents is far more interesting/useful than the number of
-physical extents for very large files. (Addresses Debian Bug:
-#631498, #644792)
-
-Logsave's usage message has been fixed. (Addresses Debian Bug:
-#619788)
-
-Avoid an infinite loop in ext2fs_find_block_device() if there are
-symlink loops in /dev caused by a buggy udev.
-
-Added a useful "fallocate" program to the contrib directory.
-
-Fixed an ABI compatibility problem in libext2fs which broke the dump
-program. Also added back some macros which dump needed so it could
-compile against the latest version of ext2_fs.h (Addresses Debian Bug:
-#636418)
-
-Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
-Debian Bug: #641667)
-
-Added internationalization support for libcom_err error table strings.
-
-Fixed various spelling mistakes found in various output strings found
-by I18N translators.
-
-Update translations: French, Chinese, Germany, Indonesian, Swedish,
-Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
-#620659)
-
-Fixed various Debian Packaging issues. (Addresses Debian Bugs:
-#614662, #632169, #641838, #627535, #629355)
-
-Updated/clarified man pages. (Addresses Debian Bugs: #639411,
-#642193, #634883)
-
-Programmer's Notes
-------------------
-
-Initial support for quota as an integrated feature, where the quota
-files are hidden system files that are automatically maintained by
-e2fsck is present, although disabled by default. It must be enabled
-by using the configure option --enable-quota.
-
-Reserved the on-disk fields for the metadata checksum and snapshot
-features, which are currently in development.
-
-The ext2fs library now has the new functions ext2fs_punch(),
-ext2fs_get_memzero() and ext2fs_file_get_inode().
-
-The ext2fs library now has support for calculating the crc32c checksum
-(via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
-
-The I/O manager now supports the discard operation.
-
-Reserved file system code points for new 1st class quota feature.
-
-Shortened the compilation lines by moving the autoconf defines to
-a config.h header file.
-
-Fixed a potential free of an unitialized pointer in
-ext2fs_update_bb_inode().
-
-Fixed miscellaneous gcc -Wall and coverity warnings.
-
-Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
-
-Fixed a build failure when OMIT_COM_ERR is defined.
-
-Improved error checking and fixed memory leaks caused by error return
-paths.
-
-Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
-the fsync() to be skipped.
-
-Added a test for extent-mapped journals by mke2fs and tune2fs.
-
-Added a test for creating a large (over 4GB) journal using mke2fs.
-
-Added a test to make sure the inode size remains constant.
-
-The regression test script now prints the list of which tests failed.
-
-The regression test system now uses /tmp for its scratch files, which
-is often a tmpfs mounted file system and hence much faster.
-
-The i_e2image test was fixed so it works with valgrind.
-
-Tests that rely on debugfs are now skipped if debugfs wasn't built.
-
-Fixed the dependencies for "make check" so all required dependencies
-are built before running the gression tests.
-
-A link to com_err.h is installed in $(includedir) during a "make install".
-
-The po/*.gmo files are automatically rebuilt if they are missing or
-out of date. This helps out Debian packaging.
-
-Allow ext2fs_get_memalign() to compile on systems that don't have
-posix_memalign().
-
-Fixed a namespace leak in libext2fs (tdb_null).
-
-
-E2fsprogs 1.41.14 (December 22, 2010)
-=====================================
-
-Fix spurious complaint in mke2fs where it would complain if the file
-system type "default" is not defined in mke2fs.conf.
-
-The resize2fs program will no longer clear the resize_inode feature
-when the number reserved group descriptor blocks reaches zero. This
-allows for subsequent shrinks of the file system to work cleanly for
-flex_bg file systems.
-
-The resize2fs program now handles devices which are exactly 16T;
-previously it would give an error saying that the file system was too
-big.
-
-E2fsck (and the libext2fs library) will not use the extended rec_len
-encoding for file systems whose block size is less than 64k, for
-consistency with the kernel.
-
-Programming notes
------------------
-
-E2fsprogs 1.41.13 would not compile on big-endian systems. This has
-been fixed. (Addresses Sourceforge Bug: #3138115)
-
-The ext2fs_block_iterator2() function passed an incorrect ref_offset
-to its callback function in the case of sparse files. (Addresses
-Sourceforge Bug: #3081087)
-
-Fix some type-punning warnings generated by newer versions of gcc.
-
-
-E2fsprogs 1.41.13 (December 13, 2010)
-=====================================
-
-E2fsck now supports the extended option "-E journal_only", which
-causes it to only do a journal replay. This is useful for scripts
-that want to first replay the journal and then check to see if it
-contains errors.
-
-E2fsck will now support UUID= and LABEL= specifiers for the -j option
-(which specifies where to find the external journal). (Addresses
-Debian Bug #559315)
-
-E2fsck now has support for the problems/<problem code>/force_no
-configuration option in e2fsck.conf, which forces a problem to not be
-fixed.
-
-Dumpe2fs will now avoid printing large negative offsets for the bitmap
-blocks and instead print a message which is a bit more helpful for
-flex_bg file systems.
-
-Mke2fs will now check the file system type (specified with the -t
-option) to make sure it is defined in the mke2fs.conf file; if it is
-not, it will print an error and abort. If the usage type (specified
-with the -T option) is not defined in mke2fs.conf, mke2fs will print a
-warning but will continue. (Addresses Debian Bug #594609)
-
-Clarified error message from resize2fs clarifying that on-line
-shrinking is not supported at all. (Addresses Debian Bug #599786)
-
-Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
-displayed. (Addresses Debian Bug #555456)
-
-E2fsck will open the external journal in exclusive mode, to prevent
-the journal from getting truncated while it is in use due to a user
-accidentally trying to run e2fsck on a snapshotted file system volume.
-(Addresses Debian Bug #587531)
-
-Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
-flag.
-
-The tune2fs program can now set the uninit_bg feature without
-requiring an fsck.
-
-The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
-default mount options settings which were added in 2.6.35.
-
-The e2fsck and dumpe2fs programs now support the new ext4 superblock
-fields which track where and when the first and most recent file
-system errors occurred. These fields are displayed by dumpe2fs and
-cleared by e2fsck. These new superblock fields were added in 2.6.36.
-
-Debugfs now uses a more concicse format for listing extents in its
-stat command. This format also includes the interior extent tree
-blocks, which previously was missing from stat's output for
-extent-based files.
-
-Debugfs has a new option, -D, which will request Direct I/O access of
-the file system.
-
-Mke2fs will skip initializing the inode table if a device supports
-discard and the discard operation will result in zero'ed blocks.
-
-Badblocks will now correctly backspace over UTF-8 characters when
-displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
-Debian Bugs #583782 and #587834)
-
-E2freefrag will now display the total number of free extents.
-
-Resize2fs -P no longer requires a freshly checked filesystem before
-printing the minimum resize size.
-
-Fixed a floating point precision error in a binary tree search routine
-that can lead to seg fault in e2fsck and resize2fs.
-
-Fixed a bug in e2fsck where if both the original and backup superblock
-are invalid in some way, e2fsck will fail going back to the original
-superblock because it didn't close the backup superblock first, and
-the exclusive open prevented the file system from being reopened.
-
-Fixed a big in e2freefrag which caused getopt parsing to fail on
-architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
-
-Clarified an mke2fs error message so a missed common in an -E option
-(i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
-results in a more understandable explanation to the user.
-
-Mke2fs now displays the correct valid inode ratio range when
-complaining about an invalid inode ratio specified by the user.
-
-Mke2fs now understands the extended option "discard" and "nodiscard",
-and the older option -K is deprecated. The default of whether
-discards are enabled by default can be controled by the mke2fs.conf
-file.
-
-Mke2fs's handling of logical and physical sector sizes has been
-improved to reflect the fact that there will be some SSD's with 8k and
-16k physical sectors arriving soon. Mke2fs will no longer force block
-size to be the physical sector size, since there will be devices where
-the physical sector size is larger than the system's page size, and
-hence larger than the maximal supported block size. In addition, if
-the minimal and optimal io size are not exported by the device, and
-the physical sector size is larger than the block size, the physical
-sector size will be used to set the Raid I/O optimization hints in the
-superblock.
-
-E2fsck will now display a better, more specific error message when the
-user enters a typo'ed device name, instead of blathering on about
-alternate superblocks.
-
-Fixed various Debian Packaging Issues
-
-Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
-#589345, #591083; Addresses Launchpad Bug: #505719)
-
-Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
-Polish, Swedish, and Vietnamese translations.
-
-
-Programmer's Notes
-------------------
-
-Fix a dependency definition for the static and profiled blkid
-libraries which could cause compile failures in some configurations.

-
-Add support for Direct I/O in the Unix I/O access layer.
-
-Fixed a memory leak in the Unix I/O layer when changing block sizes.
-
-Fixed minor memory leaks in mke2fs.
-
-Added a new function to the ext2fs library, ext2fs_get_memalign().
-
-The tst_super_size test program will check to make sure the superblock
-fields are correctly aligned and will print them out so they can be
-manually checked for correctness.
-
-Fixed some makefile dependencies for test programs in lib/ext2fs.
-
-Reserved the feature flags and superblock fields needed for the Next3
-snapshot feature.
-
-Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
-EXT4_INCOMPAT_EA_INODE.
-
-
-E2fsprogs 1.41.12 (May 17, 2010)
-================================
-
-Mke2fs now gives a correct error message if the external journal
-device is not found. (Addresses Red Hat Bug #572935)
-
-Resize2fs -P will now refuse to print a minimum size if the file
-system is not clean. Previously it would go ahead and print a minimum
-size anyway, which might not be correct, leading to user confusion.
-
-E2fsck now tests for extents that begin at physical block 0 and
-rejects them as invalid. (Addresses Google Bug: #2573806)
-
-Fixed a bug in e2fsck which could cause it to crash when trying to
-remove an invalid extent and the block bitmaps hadn't yet been loaded.
-(Addresses SourceForge Bug: #2971800)
-
-E2fsck now will completely skip time-based checks if the system clock
-looks insane or the option broken_system_clock is set in
-/etc/e2fsck.conf.
-
-E2fsck would previously report an i_blocks corruption for a 4T file
-created using posix_fallocate; this bug has been fixed.
-
-E2fsck will now correctly mark a sparse journal as invalid and will
-delete and recreate the journal to address the problem.
-
-E2fsck would previously incorrectly ask the user whether she would
-like to abort the file system check after finding a problem --- and
-then abort regardless of the user's answer. This is annoying, and
-has been fixed.
-
-E2fsck can now continue even if it fails to recreate the resize
-inode; previously it would just abort the file system check
-altogether.
-
-E2fsck could potentially remove directory entries for inodes found in
-the unused region of the inode table; this would generally happen on
-ext4 file systems that do not use journaling. This bug has been fixed
-by not clearing these directory entries once it has been established
-that bg_unused_inodes may not be trustworthy; once pass #2 has been
-completed, e2fsck will restart the file system check from the
-beginning, and then it will be safe to delete any directory entries
-pointing to inodes that appear to be deleted. (Addresses Google Bug:
-#2642165)
-
-E2fsck will not try to set the block group checksums if the user
-cancels the fsck with a control-C. It's a bad idea to set the
-checksums if e2fsck hasn't been completed, and it often results an the
-error message, "Inode bitmap not loaded while setting block group
-checksum info". (Addresses Launchpad Bug: #582035)
-
-The mke2fs program now queries the kernel for the physical as well as
-the logical sector size, and will not allow a blocksize below the
-logical, and will strongly encourage a blocksize at least as big as
-the physical blocksize. This is needed for 4k sector drives that
-emulate 512 byte sector sizes.
-
-Mke2fs will now allow a flex_bg size of 1. This is unusual, and
-rarely needed, but it is a legal value.
-
-E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
-not needed, and offer to clear it; this is a sign of a kernel bug, but
-more importantly, some released kernels may crash when this situation
-is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
-
-E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
-i_size is correct. (Kernels starting with 2.6.34 will set
-EOFBLOCKS_FL.)
-
-The com_err library will now only output ^M (a CR character) when the
-tty is in raw mode.
-
-Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
-and Vietnamese translations.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs: #571247, #563487)
-
-
-Programmer's Notes
-------------------
-
-The regression test suite now uses its own mke2fs.conf file, so that
-downstream distributions want change the mke2fs.conf file which is
-distributed in the RPM or dpkg file, without worrying about screwing
-up the regression test results.
-
-Always build namei.o so that building with configure --disable-debugfs
-works correctly. Long-term, if we care about reduced e2fsprogs
-builds, we need a more general solution for deciding what .o files are
-needed for a particular build. Given that install floppies are going
-(gone?) the way the dodo bird, we probably don't care, though.
-(Addresses Sourceforge Bug: #2911433)
-
-Add configure options --enable-symlink-build and
---enable-symlink-install, which allow e2fsprogs be built using
-symlinks instad of hard links, and to be installed using symlinks
-instead of hard links, respectively. It is useful when the file
-system where the build is taking place, or the file system where
-e2fsprogs is installed, can't handle hard links for some reason.
-(Addresses Sourceforge Bug: #1436294)
-
-Fixed compile warning in mke2fs.c.
-
-
-E2fsprogs 1.41.11 (March 14, 2010)
-==================================
-
-E2fsck will no longer give a fatal error and abort if the physical
-device has been resized beyond 2**32 blocks. (Addresses Launchpad
-Bug: #521648)
-
-Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
-the allocation status of the block <blk>. (Addresses Debian Bug:
-#564084)
-
-E2fsck now prints a much more emphatic and hopefully scary message
-when a file system is detected as mounted while doing a read/write
-check of the filesystem. Hopefully this will dissuade users from
-thinking, "surely that message doesn't apply to *me*" :-(
-
-E2fsck -n will now always open the file system read-only. We now
-disallow certain combination of options which previously were manual
-exceptions; this is bad because it causes users to think they are
-smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
--D" are no longer supported. (Addresses Launchpad Bug: #537483)
-
-In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
-it detected a badly aligned partition. Unfortunately, this broke some
-distribution installation scripts, so it now just prints the warning
-message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
-Launchpad Bug: #530071)
-
-Mke2fs would take a long time to create very large journal files for
-ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
-now fixed.
-
-E2fsck now understands the EOFBLOCKS_FL flag which will be used in
-2.6.34 kernels to make e2fsck not complain about blocks deliberately
-fallocated() beyond an inode's i_size.
-
-E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
-e2fsck -fD can corrupt non-indexed directories when are exists one or
-more file names which alphabetically sort before ".". This can happen
-with ext2 filesystems or for small directories (take less than a lock)
-which contain filenames that begin with a space or some other
-punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
-Bug: #525114)
-
-
-Programmer's Notes
-------------------
-
-Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
-correctly.
-
-The libcom_err function now has support for Heimdal's com_right_r
-function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian
-Bug: #558910)
-
-
-E2fsprogs 1.41.10 (February 7, 2010)
-====================================
-
-Fix resize2fs bug which causes it to access invalid memory.
-
-Add libss support for libreadline.so.6.
-
-Fix e2fsck's check for extent-mapped directory with an incorrect file
-type.
-
-Add new e2fsck.conf configuration option, default/broken_system_clock
-to support systems with broken CMOS hardware clocks. Also, since too
-many distributions seem to have broken virtualization scripts now,
-e2fsck will by default accept dates which are off by up to 24 hours by
-default. (Addresses Debian Bugs: #559776, #557636)
-
-Fix a bug where mke2fs may not use the best placement of the inode
-table when there is only room for a single block group in the last
-flex_bg.
-
-E2fsck is now smarter when it needs to allocate blocks in the course
-of fixing file system problems. This reduces the number of spurious
-differences found in pass #5.
-
-E2fsck will no longer rehash directories which fit in a single
-directory block.
-
-E2fsck now correctly handles holes in extent-mapped directories (i.e.,
-sparse directories which use extents).
-
-Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
-
-Fix a bug in filefrag where on platforms which can allow file systems
-with 8k blocks, that it doesn't core dump when it sees a file system
-with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
-out.)
-
-E2fsck will correctly fix directories that are have an inaccurate
-i_size as well as other problems in a single pass, instead of
-requiring two e2fsck runs before the file system is fully fixed.
-
-Fix e2fsck so it will correctly find and detect duplicate directory
-entries for non-indexed directories. ( Addresses Sourceforge Bug:
-#2862551)
-
-Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
-thinly-provisioned storage device. This can be disabled using the -K
-option.
-
-Enhance libext2fs so it works around bug in Linux version 2.6.19
-and earlier where the /proc/swaps file was missing the header on
-the first line.
-
-Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
-was missing the header on the first line.
-
-Fix some big-endian bugs in e2fsck and libext2fs.
-
-Fix resize2fs so it works correctly on file systems with external
-journals instead of failing early with the error "Illegal inode
-number".
-
-Fix libss so that it does not seg fault when using a readline library
-which does not supply a readline_shutdown() function.
-
-Updated dumpe2fs's usage message so it correctly gives the right
-arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
-(Addresses Launchpad Bug: #448099)
-
-Teach libext2fs to ignore the high 32 bits of the i_blocks field
-when huge_file file system feature is set, but the inode does not
-have the HUGE_FILE_FL flag set.
-
-Fix e2fsck's handling of 64-bit i_blocks fields.
-
-E2fsck will now print "Illegal indirect block", "Illegal
-double-indirect block", etc., instead of "Illegal block #-1" or
-"Illegal block #-2", etc. This makes it easier for users to
-understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
-
-Mke2fs now will obtain get device topology information from blkid and
-use it to populate the superblock stride and stripe sizes. It will
-also warn if the block device is misaligned
-
-Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug:
-##524526)
-
-Fix the libext2fs library code to round up the bitmap size to a 4-byte
-boundary, to prevent spurious seg faults caused by the x86
-architecture. This doesn't affect Linux systems, but was a major
-problem on a number of *BSD systems. (Addresses Sourceforge Bug:
-#2328708)
-
-Fix resize2fs's minimum size required for a file system so it doesn't
-fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131)
-
-Dumpe2fs now prints summary information about the contents of the
-journal.
-
-Avoid printing scary error messages when e2fsck starts running
-problems on low-memory systems, as it tends to panic and mislead the
-user. (Addresses Debian Bug: #509529)
-
-Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
-modules files. (Address Red Hat Bug: #518572)
-
-Fix tune2fs so it can add a journal when an extent-enabled file system
-is mounted. (Addresses Launchpad bug: #416648)
-
-Update Czech, Indonesian, Polish and Vietnamese translations (from the
-Translation Project).
-
-Update/clarify man pages. (Addresses Sourceforge Bug: #2822186)
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs: #540111)
-
-Programmer's Notes
-------------------
-
-The configure script supports the --with-cc, --with-ccopts, and
---with-ldopts options. Instead, the more standard use of CC=,
-CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
-Also, --with-ld, which never worked, was also removed.
-(Addresses Sourceforge Bug: #2843248)
-
-The in-tree header files are only used if the in-tree uuid or blkid
-libraries are used. Otherwise, use the system-provided uuid or blkid
-header files if using the system-provided libraries.
-
-Fix some build failures caused by --disable-* configure options.
-
-Work around a bug in autoconf 2.64.
-
-
-E2fsprogs 1.41.9 (August 22, 2009)
-==================================
-
-Fix a bug in e2fsck routines for reallocating an inode table which
-could cause it to loop forever on an ext4 filesystem with the FLEX_BG
-filesystem feature with a relatively rare (and specific) filesystem
-corruption. This fix causes e2fsck to try to find space for a new
-portion of the inode table in the containing flex_bg, and if that
-fails, the new portion of the inode table will be allocated in any
-free space available in the filesystem.
-
-Make e2fsck less annoying by only asking for permission to relocate a
-block group's inode table once, instead of for every overlapping
-block. Similarly, only ask once to recompute the block group
-checksums, instead of once for each corrupted block group's checksum.
-
-Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
-not present, and it needs to fall back to using the FIBMAP ioctl.
-
-Fix filefrag to correctly print the number of extents for zero-length
-files. (Addresses Debian Bug: #540376)
-
-Filefrag now has a -B option which forces the use of the FIBMAP ioctl
-to more easily debug the FIBMAP code.
-
-Fixed filefrag for non-extent based files.
-
-Add a new program, e2freefrag, which displays information about the
-free space fragmentation in an ext2/3/4 filesystem.
-
-Fix inode resizing via tune2fs -I so that it works correctly in the
-face of non-empty bad blocks inodes, and if the filesystem was
-formatted using the "mke2fs -E stride=N" option for RAID arrays.
-
-Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
-and corrupt large directories if the directory needs to shrink by more
-than one block. (Addresses Debian Bug: #537510)
-
-Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
-last mount times are in the future, they are corrected even if
-buggy_init_scripts is set. This is needed because otherwise resize2fs
-will refuse to resize the filesystem, even after running "e2fsck -f".
-(Addresses Launchpad bug: #373409)
-
-E2fsck will now print much fuller information when the last mount time
-or last written time is in the future, since most people can't seem to
-believe their distribution has buggy init scripts, or they have a
-failed CMOS/RTS clock battery.
-
-Enhance dumpe2fs to dump the extent information via the 'stat'
-command, and more detailed extent information via the new command
-'dump_extents'.
-
-Update French, Polish, Czech, and Sweedish translation from the
-Translation Project.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details.
-
-Programmer's Notes
-------------------
-
-Fixed miscellaneous gcc -Wall warnings.
-
-Fixed memory leak in error path in ext2fs_block_iterate2()
-
-Fixed non-Linux build of the intl directory by adding support for the
-E/Q/V macros.
-
-The bitmap read/write functions now treat uninitialized bitmaps as
-unallocated; this fixes a number of problems in all e2fsprogs for ext4
-filesystems when there is a need to allocate new blocks or inodes, and
-there aren't any free blocks or inodes in the already-used block
-groups.
-
-Improve ext2fs_extent_set_bmap() to avoid creating new extents which
-get inserted into the extent tree when they are not needed.
-
-
-E2fsprogs 1.41.8 (July 11, 2009)
-================================
-
-Fix resize2fs's online resizing, fixing a regression which in
-e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
-
-Fix potential filesystem corruptions caused by using resize2fs to
-shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
-Bug: #510379)
-
-Optimize uuid_generate() to avoid running uuidd if it is not setuid or
-setgid and the currently running program doesn't have write access to
-the uuidd work directory.
-
-Add safety checks (for non-Linux systems) so that uuidd isn't run with
-file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
-will be careful not to close the file descriptor for its unix domain
-socket when it detaches itself from the controlling tty. Also add
-safety checks so that if the unix domain socket between the uuid
-library and uuidd program is closed for any reason, both the library
-and the uuidd will return an appropriate error code instead of looping
-in an infinite loop.
-
-The e2croncheck script, which creates an LVM snapshot and then checks
-the ext3/4 filesystem via the LVM snapshot, has been added to the
-contrib directory.
-
-Fix filefrag program for files that have more than 144 extents.
-
-Update French, Polish, Czech, Indonsian, and Sweedish translation from
-the Translation Project.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bug #535530)
-
-Update/clarify man pages.
-
-Programmer's Notes
-------------------
-
-Fix compilation problem when configured with --disable-uuid.
-
-Don't build uuidgen if configured with --disable-uuid.
-
-Add the new library function ext2fs_test_inode_bitmap_range(), and
-optimized ext2fs_test_block_bitmap_range(), which will be needed for
-future optimizations for e2fsck.
-
-Fix makefile dependencies for libcom_err so that the Makefiles work
-well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
-
-Enhance the build system so that the full set of commands executed by
-the Makefiles are displayed, instead of the Linux kernel summary
-output, if the build was configured with --enable-verbose-makecmds, or
-if GNU make is in use and the V variable is non-null, i.e., via "make
-V=1".
-
-
-E2fsprogs 1.41.7 (June 29, 2009)
-================================
-
-Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
-uninitalized data into the portion of the inode beyond the first 128
-bytes when operating on inodes mapped via extents; potentially
-corrupting filesystems.
-
-Fix memory leaks in e2fsprogs, including a very large memory leak
-which can cause e2fsck to run out of memory when checking very large
-filesystems using extents.
-
-The logsave program will now filter out the ^A and ^B characters when
-writing to the console.
-
-Harden ext2fs_validate_entry() so that lsdel will not read beyond the
-end of the block even if the directory block is corrupted.
-
-Fix debugfs from core dumping if the logdump command fails to open the
-output file.
-
-Enhance badblocks to print the currently tested block number when
-interrupted with ^C.
-
-Fix lsattr to exit with a non-zero status when it encounters errors.
-(Addresses RedHat Bugzilla #489841)
-
-Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
-filesystems as the kernel when encoding rec_len >= 64k. For 64k
-filesystems (currently all that is supported by e2fsprogs, this is
-only a minor corner case).
-
-Resize2fs will now update the journal backup fileds in the sup0erblock
-if the journal is moved; this avoids an unnecessary full fsck after
-resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
-
-Fix libext2fs to properly initialize i_extra_size when creating the
-journal and resize inodes.
-
-Change badblocks to allow block sizes larger than 4k.
-
-Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
-
-Update Chinese and Czech translation from the Translation Project.
-
-Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
-
-
-Programmer's Notes
-------------------
-
-Add --disable-libuuid option to configure which uses an in-system
-installed version of libuuid; the private version is enabled by
-default.
-
-Add --valgrind-leakcheck option to the test_script program which runs
-valgrind with the appropriate options to find memory leaks.
-
-
-E2fsprogs 1.41.6 (May 30, 2009)
-===============================
-
-Fix a critical regression in e2fsck introduced version 1.41.5 which
-can undo updates to the block group descriptors after a journal replay.
-
-If e2fsck receives an I/O error while replaying the journal, prompt
-the user whether they want to ignore the error or not; if e2fsck is
-run in preen mode, force fsck to abort the preen pass.
-
-Fix a bug which would cause e2fsck to core dump if the filesystem
-contains a corrupt extent header, and the user declines to clear the
-inode. (Addresses Sourceforge Bug: #2791794)
-
-Fix e2fsck to restart only once in the case of multiple block groups
-which inodes in use that are in the uninitialized part of the block
-group's inode table.
-
-To reduce user confusion, if the /etc/mtab file is missing
-ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
-new, explicit error code to indicate this case. This will cause
-e2fsck to give a clearer error message when the user is using buggy
-rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
-Bug: #527859)
-
-Fix e2fsck so that if the primary group descriptors are corrupted, but
-the backup superblock is entirely invalid, to go back to using (and
-fixing) the priary group descriptors instead of completely giving up
-on the filesystem. (Addresses Debian Bug: #516820)
-
-Change e2fsck to not abort a preen pass if an inode is found to have
-i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
-kernels (post 2.6.29) will ignore this field. So let's fix it
-automatically during the preen pass instead of forcing the user to fix
-this up manually. (Addresses Debian Bug: #526524)
-
-Add resource tracking for e2fsck passes 1b through 1d.
-
-Speed up e2fsck by eliminating unnecessary journal checks if the
-filesystem is already mounted and doesn't need recovery (since the
-kernel would have run the journal when the filesystem was mounted.)
-Also speed up e2fsck by avoiding unnecessary block group descriptor
-updates in ext2fs_close().
-
-Add support to chattr to migrate inodes from using direct/indirect
-blocks to extents.
-
-Avoid corrupting the filesystem if there is an attempt to shrink a
-filesystem using resize2fs smaller than posible by making
-ext2fs_set_bmap() more careful not to delete the old block until the
-new block can be inserted. In addition, fix a bug in how the minimum
-size of the filesystem (plus a safety margin) is calculated, and
-modify resize2fs to refuse to shrink the filesystem below that minimum
-size without the force flag.
-
-Teach blkid to try to figure out DM device names using take advantage
-of information in sysfs when running on kernels (2.6.29 and later)
-which provide this information in /sys/block/dm-<N>/dm/name; this is
-much faster than scanning for the devncie number in /dev/mapper.
-
-Fix blkid to prefer /dev/mapper/<name> device names instad of the
-private /dev/dm-X names.
-
-Add an -a option to debugfs's close_filesys command which writes any
-changes to the superblock or block group descriptors to all of the
-backup superblock locations.
-
-Add support to the filefrag program to use the FIEMAP ioctl.
-
-Update Chinese translation from the Translation Project.
-
-Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
-Launchpad Bug: #381854)
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bug #506064)
-
-
-Programmer's Notes
-------------------
-
-Add test code to make sure e2fsck's problem.c doesn't have two problem
-codes assigned to duplicate values.
-
-Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
-(Addresses Sourceforge Bug: #2780205)
-
-Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
-function declaration for init_resource_track() and
-print_resource_track() when RESOURCE_TRACK is not defined.
-
-The test code which is used to build the tst_csum progam has been
-moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
-avoid compile problems caused by not having a prototype for
-ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
-
-Update the config.guess and config.sub file to the latest from the
-FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
-Debian Bug: #528330)
-
-Add a new function, ext2fs_extent_open2(), which behaves like
-pext2fs_extent_open(), but uses the user-supplied inode structure
-when opening an extent instead of reading the inode from disk.
-
-
-E2fsprogs 1.41.5 (April 23, 2009)
-=================================
-
-Fix a number of filesystem corruption bugs in resize2fs when growing
-or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
-is not mounted).
-
-Debugfs can now set i_file_acl_high via the set_inodes_field command,
-and print a 64-bit file acl. This is useful for debugging filesystem
-corruptions where the high bits of i_file_acl_high are set. E2fsck
-will detect and fix non-zero i_file_acl_high on 32-bit filesystems
-since some Linux kernel versions pay attention to this field even when
-they shouldn't.
-
-Speed up e2fsck when checking clean filesystems by avoiding
-unnecessary block reads, and coalescing the block group descriptor
-blocks so they are read using a single read operation.
-
-The libuuid library will now close all file descriptors before running
-uuidd. This avoids problems when the calling program has open sockets
-which then never get closed because uuidd is a long-running helper
-daeomn. (Addresses Launchpad bug: #305057)
-
-In order to avoid unnecessary full filesystem checks by e2fsck after
-an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
-the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
-
-Mke2fs will avoid trying to create the journal when run in
-superblock-only mode (mke2fs -S), since the left-over journal in the
-inode table will cause mke2fs to fail.
-
-Fix a bug in libext2fs functions that check to see if a particular
-device or filesystem image is mounted, which would cause these
-functions to report that a file identical to the (relative) pathname
-used by a pseudo-filesystem was mounted when in fact it was not.
-
-Update Czech translation from the Translation Project.
-
-Add Chinese (simplified) translation from the Translation Project.
-
-Fix support for external journals (which was broken in e2fsprogs
-1.41.4).
-
-Fix a regression in debugfs where the "stat" command when no
-filesystem was open would cause debugfs to crash with a segmentation
-violation.
-
-Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
-used to support filesystems without a journal. Update the blkid
-library so it understands this.
-
-The blkid library will remove an entry from the blkid cache
-representing the entire disk if partitions are found, since presuambly
-the device previously had no partition table, but has now transitioned
-to using a partition table.
-
-Add a check to mke2fs and tune2fs that the argument to the -m option
-(which specifies the reserved ratio) must be greater than zero.
-(Addresses Debian Bug: #517015)
-
-Add support for tracking the number kilobytes written to the
-filesystem via the superblock field s_kbytes_written. It will be
-updated by the kernel as well as by e2fsprogs programs which write to
-the filesystem. This is useful for tracking the wear to filesystems
-on Solid Sstate Drives.
-
-Fix compatibility issue in the libext2fs info file and makeinfo
-version 4.12. (Addresses Red Hat Bugzilla: #481620)
-
-Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bug: #506279)
-
-Programmer's Notes
-------------------
-
-Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
-Bug: #521602)
-
-Fix various gcc compilation warnings and other programming cleanups.
-(Addresses Red Hat Bugzilla: #486997)
-
-Add support for building the blkid command statically.
-
-Add support for disabling the built-in blkid library in favor of a
-system-installed blkid implementation via the configure option
---disable-libblkid.
-
-
-E2fsprogs 1.41.4 (January 27, 2009)
-===================================
-
-Fixed a bug which could sometimes cause blkid to return an exit value
-of zero for a non-existent device (Addresses Debian Bug: #502541)
-
-Blkid will now recognize ext3 filesystems that have the test_fs flag
-set as ext3 filesystems.
-
-The blkid library will now recognize btrfs filesystems and swap
-devices currently used by user-level software suspend.
-
-Tune2fs now updates the block group checksums when changing the UUID
-to avoid causing e2fsck to complain vociferously at the next reboot.
-
-Tune2fs's inode size resizing algorithms have been fixed so it is not
-vastly inefficient for moderate-to-large filesystems, due to some
-O(n**2) and O(n*m) algorithms that didn't scale well at all.
-
-Fix tune2fs's inode resizing algorithm so it will not corrupt
-filesystems laid out for RAID filesystems; in addition, tune2fs will
-refuse to change the inode size for filesystems that have the flex_bg
-feature enabled. (This is a limitation in the current implementation
-of tune2fs -I.)
-
-E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
-filesystems with 32-bit block numbers, when the headers for 64-bit
-block numbers was added. This regression has been fixed.
-
-Debugfs's ncheck command has been fixed to avoid printing garbage
-characters at the end of file names.
-
-Fix resize2fs for ext4 filesystems. Some blocks that that need moving
-when shrinking filesystems with uninit_bg feature would not be moved.
-In addition, blocks and inode table blocks were not being correctly
-freed when shrinking filesystems with the flex_bg feable, which caused
-resize2fs -M to fail. Finally, when blocks are moved, make sure the
-uninitialized flag in extents is preserved.
-
-Fix bug which caused dumpe2fs to abort with an error if run on a
-filesystem that contained an external journal.
-
-Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
-for this in argv[0] to provide better legacy support for these
-distributions. This is a practice that should NOT be continued,
-however.
-
-Mke2fs now has a new option -U, which allows the user to specify the
-UUID that should be used for the new filesystem.
-
-Mke2fs will treat devices that are exactly 16TB as if they were 16TB
-minus one block. This allows users who have read that ext3 supports
-up to 16TB filesystems and who create a 16TB LVM to not get confused,
-since the true limit is really 16TB minus one block.
-
-E2fsck will no longer abort an fsck run if block group has an errant
-INODE_UNINIT flag.
-
-E2fsck now distinguishes between fragmented directories and fragmented
-files in verbose mode statistics and in the fragcheck report.
-
-Fix a bug in e2fsck which casued it double count non-contiguous
-extent-based inodes.
-
-E2fsck will leave some slack space when repacking directories to allow
-room for a few directory entries to be added without causing leaf
-nodes to be split right away.
-
-Fix a bug which caused e2fsck to crash when it comes across a
-corrupted interior node in an extent tree with the error message:
-"Error1: Corrupt extent header on inode XXXXXX"
-
-E2fsck problem descriptions involving the journal are no longer
-referred to as "ext3" problems, since ext4 filesystems also have
-journals.
-
-Fix a long-standing bug in e2fsck which would cause it to crash when
-replying journals for filesystems with block sizes greater than 8k.
-
-Update Catalan translation from the Translation Project.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs: #503057, #502323, #511207)
-
-Programmer's Notes
-------------------
-
-Fix build of e2fsck.profiled, and add support for building profiled
-binaries in the misc directory if configured with --enable-profile.
-
-The ext2fs_open() function now performs more sanity checks on the
-superblock to avoid potential divide by zero errors by other parts of
-library.
-
-The ext2fs_read_inode_full() function now has a safety check to avoid
-a segmentation fault on corrupted filesystems.
-
-The ext2fs_new_inode() function now has a sanity check so that if the
-s_first_inode field in the superblock is insane, it will return
-EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
-
-To avoid segmentation faults, ext2fs_block_alloc_stats() and
-ext2fs_inode_alloc_stats() now validates the passed inode or block
-number to avoid overrunning an array boundary.
-
-Various signed/unsigned errors for variables containing block numbers
-have been fixed.
-
-Accomodations for gcc's stupidity in not realizing that constant
-strings that do not contain a '%' character are safe to use in format
-strings have been made so that distributions that want to compile
-e2fsprogs with -Werror=format-security have an easier time doing so.
-
-Added a new 64-bit getsize interface, ext2fs_get_device_size2().
-
-Added the utility make-sparse.c to the contrib directory.
-
-The ext2fs_block_iterate2() function now reflects errors from
-ext2fs_extent_set_bmap() to the caller, if the callback tries to
-change a block on an extent-based file, and ext2fs_extent_set_bmap()
-fails for some reason (for example, there isn't enough disk space to
-split a node and expand the extent tree.
-
-The ext2fs_block_iterate2() function will preserve the uninit flag in
-extents when the callback function modifies a block in an extent-based
-file.
-
-E2fsck will now flag filesystems that have an insane s_first_ino field
-in their superblock, and attempt to use a backup superblock to repair
-the filesystem.
-
-
-E2fsprogs 1.41.3 (October 12, 2008)
-===================================
-
-E2fsck has been fixed so it prints the correct inode number for
-uinit_bg related problems.
-
-E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
-is available on linux. This can be disabled via a configuration
-option in /etc/e2fsck.conf.
-
-Fix a file descriptor leak in libblkid when checking to see if an ext4
-or ext4dev module exists.
-
-Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
-while trying to close a filesystem can lead to infinite loops.
-(Addresses Red Hat Bugzilla #465679)
-
-Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
-will cause resize2fs to drop into an infinite loop. (Addresses Red
-Hat Bugzilla: #465984)
-
-Add a check in the Unix I/O functions in libext2fs so that when a
-device is opened read/write, return an error if the device is
-read-only using the BLKROGET ioctl.
-
-Fix debugfs's ncheck command so that it prints all of the names of
-hardlinks in the same directory.
-
-Fix a bug in libblkid so it correctly detects whether the ext4 and
-ext4dev filesystems are available, so that the ext4dev->ext4
-fallback code works correctly.
-
-Programmer's Notes
-------------------
-
-Fix a parallel build problem by making sure util/subst is built before
-trying to build the lib/et directory. (Addresses Sourceforge Bug:
-#2143281)
-
-Updated "make depend" information for crc16.o
-
-
-E2fsprogs 1.41.2 (October 2, 2008)
-==================================
-
-Fix e2fsck's automatic blocksize detection. This fixes a regression
-from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
-specifies a block number using the -b option if the blocksize option
-isn't also specified using -B. Unfortunately, users very commonly
-invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
-superblock; in fack e2fsck will often suggest this kind of command
-line. Oops.
-
-Enhance the debugfs's "ncheck" command so it will print all of the
-pathnames for the specified inodes. (Previously, in some cases ncheck
-might not print a pathname for an inode at all if some of the other
-inodes had multiple hard links.)
-
-Enhance debugfs's "hash" command so the hash seed can be specified via
-a command-line option. In addition, allow the hash algorithm to be
-specified by name instead of just by number.
-
-Fix e2fsck so that we don't accidentally print the translation file's
-header when asking the user a custom question so there is no prompt
-defined for a particular problem record. For example, the question
-"Run journal anyway" will get the PO header tacked on because e2fsck
-erroneously passed the null string to _(). (Addresses Launchpad Bug:
-#246892)
-
-Enhance badblocks so that it can test a normal file which is greater
-than 2GB.
-
-Enhance the badblocks command so that it displays the time and
-percentage complete when in verbose mode. (Addresses Debian Bug:
-#429739)
-
-Fix a potential memory leak in a error handling path in debugfs's
-ncheck function.
-
-Fix a potential memory corruption problem if a memory allocation fails
-in resize2fs.
-
-Fix the usage message for debugfs's logdump command to be consistent
-with its man manpage.
-
-Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
-and Sweedish translation from the Translation Project.
-
-Add documentation for the file I/O functions to the libext2fs.texinfo
-file. (Addresses Debian Bug: #484877)
-
-Update and clarified various man pages. (Addresses Launchpad Bug
-#275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bug: #497619)
-
-Programmer's Notes
-------------------
-
-Fix a potential file descriptor leack in libcom_err by setting the
-close-on-exec flag for a fd used for debugging. (Addresses Red Hat
-Bugzilla #464689)
-
-Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
-has been carrying a patch for a long time to prevent a largely
-theoretical race condition if a multi-threaded application adds and
-removes error tables in multiple threads. Unfortunately SuSE's
-approach breaks compatibility by forcing applications to link and
-compile with the -pthread option; using pthread mutexes has
-historically been problematic. We fix this by using sem_post/sem_init
-instead.
-
-Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
-Sourceforge Bug: #2087502)
-
-Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
-libraries when using ELF shared libraries.
-
-Fix ELF shared library when building on systems that don't already
-have the e2fsprogs shared libraries already installed. (Addresses
-Sourceforge Bug: #2088537)
-
-Fix the pkg-config files so they work correctly when linking with
-static libraries and fix the include directory so programs don't have
-to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
-instead. (Addresses Sourceforge Bug: #2089537)
-
-Make sure ext2fs_swab64() is compiled for all platforms, and not just
-for x86. (Addresses Debian Bug: #497515)
-
-Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
-non-x86 platforms. (They had been removed for x86 earlier.)
-
-Fix diet libc compilation support, which had bitrotted due to lack of
-TLC. Fixing this improves general portability.
-
-When installing the link library when using ELF shared libraries,
-avoid using absolute pathnames if the link library and the shared
-library are installed in the same directory. (Addresses Sourceforge
-Bug: #1782913)
-
-Fix gen-tarball so it will work even if the top-level directory has
-been renamed to something other than "e2fsprogs". Also make
-gen-tarball print the size of the resulting tar.gz file.
-
-
-E2fsprogs 1.41.1 (September 1, 2008)
-====================================
-
-Many people are forgetting to update their mke2fs.conf file, and this
-causes ext3, ext4, and ext4dev filesystems won't get created with the
-proper features enabled. We address this in two ways. First, mke2fs
-will issue a warning if there is not definition for an ext3, ext4, or
-ext4dev filesystem and the user is trying to create such a filesystem
-type. Secondly, when installing from a source build, "make install"
-will provide basic configuration file handling for /etc/mke2fs.conf.
-If it exists, and does not mention ext4dev, it will be moved aside to
-/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
-be installed. If the existing /etc/mke2fs.conf file does mention
-ext4dev, then "make install" will install official mke2fs.conf file as
-/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
-they should look to see if any changes need to be merged.
-
-The mke2fs program will now create the journal in the middle of the
-filesystem, since this minimizes seek times on average for fsync-heavy
-workloads. In addition, mke2fs will now create journals using extents
-for filesystems that support them. This results in a more efficient
-encoding for the journal since it eliminates the need for using
-indirect blocks.
-
-The mke2fs program will avoid allocating an extra block to the
-journal. (Addresses Sourceforge Bug: #1483791)
-
-Mke2fs will correctly enforce the prohibition against features
-(specifically read-only features) in revision 0 filesystems. (Thanks
-to Benno Schulenberg for noticing this problem.)
-
-Mke2fs previously would occasionaly create some slightly non-optimally
-placed inode tables; this bug has been fixed.
-
-The mke2fs and tune2fs programs now print the correct usage message
-describing the maximum journal size. (Addresses Debian Bug: #491620)
-
-Add support for setting the default hash algorithm used in b-tree
-directories in tune2fs (from a command-line option) or mke2fs (via
-mke2fs.conf). In addition, change the default hash algorithm to
-half_md4, since it is faster and better.
-
-The blkid library will now recognize MacOS hfsx filesystems, and
-correctly extract the label and uuid for hfs, hfsx, and hfsplus
-filesystems. (Addresses Sourceforge Feature Requests: #2060292)
-
-The blkid library has improved detection of JFS and HPFS filesystems.
-(Addresses Launchpad Bug: #255255)
-
-The blkid library is now much more efficiently handling devicemapper
-devices, mainly by no longer using the devicemapper library. This can
-speed up access for systems with a large number of device mapper
-devices.
-
-Blkid had a number of cache validation bugs in libblkid that have been
-fixed. (Addresses Debian Bug: #493216)
-
-Resize2fs will now properly close out the "updating inode references"
-progress bar so there is a newline printed before printing the final
-"resize is successful" message.
-
-Resize2fs will now correctly handle filesystems with extents and/o
-uninitialized block groups correctly when file/directory blocks need
-to relocated (i.e., when shrinking a filesystem or if the resize_inode
-is not present). To support this, the ext2fs library now supports
-initializing inode and block bitmaps that are not yet initialized when
-allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
-addition, e2fs_block_iterate2() can now support changing the location
-of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
-been optimized to avoid creating unnecessary new extents when updating
-the location of blocks in the extent tree. This will also help out
-e2fsck's recovery of obscurely corrupted filesystems with extents,
-when blocks are claimed by multiple inodes.
-
-Add support for on-line resizing ext4 filesystem with the flex_bg
-filesystem feature. The method for doing so is not optimal, but to do
-a better job will require kernel support.
-
-E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
-debugfs programs to not be able to read e2image files; the signed
-vs. unsigned bug in the code which read bitmaps from the e2image has
-been fixed. (Addresses Debian Bug: #495830)
-
-Resize2fs is now correctly managing the directory in-use counts when
-shrinking filesystems and directory inodes needed to be moved from one
-block group to another. This bug has been around since e2fsprogs
-1.26, and is largely harmless, but does cause a filesystem corruption
-which will be flagged by e2fsck after the filesystem has been shrunk.
-
-E2fsck will no longer issue spurious complaints about the inode size
-caused by very large extent-based files, and by blocks reallocated
-using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
-Kernel Bugzilla: #11341)
-
-Mke2fs will now set the creation timestamp on the lost+found directory
-and the root directory. (More generally, all new inodes created using
-the ext2fs library will correctly set the creation timestamp.)
-
-E2fsck now correctly calculates ind/dind/tind statistics in the
-presence of extent-based files. In addition, "e2fsck -v" will report
-statistics of the depth of extent trees in the filesystem. E2fsck can
-also give an inode fragmentation report using "e2fsck -E fragcheck"
-which can be useful when debugging the kernel block allocation
-routines.
-
-Fix support for empty directory blocks in ext4 filesystems with 64k
-blocksize filesystems.
-
-E2fsck will now print the depth of corrupt htree directories.
-
-Debugfs's htree command now correctly understands extent-based
-directories. It will also print out the minor hash as well as the
-major hash.
-
-Debugfs has a new command which will print the supported features of
-e2fsprogs, to enable scripts to know whether the installed version of
-e2fsprogs can support a specific feature.
-
-Debugfs will now write files using extents for filesystems that
-support them.
-
-The error message printed by "tune2fs -I" if the inode size was too
-small was rather confusing, so it has been improved. Also, we won't
-try to create an undo log until we know that command-line-specified
-parameters such as "tune2fs -I <inode size>" are valid.
-
-Given some filesystems found "in the wild" that had non-zero block
-group checksums even though the uninit_bg/gdt_sum feature was not
-enabled, e2fsck would issue spurious error messages. Teach
-ext2fs_group_desc_csum_verify() to ignore the block group checksum
-entirely if the feature flag is not set. (Addresses Debian Bug:
-#490637)
-
-The blkid program will now print out a user-friendly listing of all of
-the block devices in the system and what they contain when given the
--L option. (Addresses Debian Bug: #490527)
-
-The filefrag program now has a more accurate calculation for the
-number of ideal extents. (Addresses Debian Bug: #458306)
-
-The test I/O manager is now enabled by default, but its overhead is
-only incurred when it would be enabled via the TEST_IO_FLAGS or
-TEST_IO_BLOCK environment variables.
-
-Typographical errors in various program strings and usage messages
-have been fixed; most of these were pointed out by the e2fsprogs
-message catalog translators. (Thanks, translators!)
-
-Update and clarified various man pages, as well as some typographical
-errors in the libext2fs texinfo file.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details.
-
-Add Indonesian and update French, Polish, Dutch, German, Sweedish,
-Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
-#401092)
-
-Programmer's Notes
-------------------
-
-Fix portability problem with the badblocks group; for systems that
-don't have nanosleep(), try using usleep() instead.
-
-The "make check" target in the e2fsck directory now sets
-LD_LIBRARY_PATH before running the various e2fsck internal library
-regression tests.
-
-The crc32 regression test in the e2fsck library is now portable to
-greater varienty of environments, including big-endian systems and
-when cross-building e2fsprogs for embedded systems. (Addresses
-Sourceforge Bug: #2019287)
-
-The ext2fs_extent_set_bmap() had some bugs when setting the first
-block in a file, or when replacing a single block extent. Those cases
-fortunately were came up relatively rarely when e2fsck was checking
-files, but caused some problems when resize2fs was shrinking
-extent-based files.
-
-Fix a potential core-dumping bug in libe2p's iterate_on_dir()
-function.
-
-Various ext2fs library functions --- ext2fs_block_iterate2(),
-ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
-allocated memory to avoid memory leaks in all of their error return
-paths.
-
-Ext2ed was failing to build because masix support had been removed in
-the rest of e2fsprogs, so ext2ed no longer has masix support, either.
-
-The configure script now respects the LDFLAGS environment variable if
-it is set when configure is called. (Addresses Sourceforge Feature
-Request: #1937287)
-
-Libuuid is now more portable to the Windows platform. (Addresses
-Sourceforge Feature Request: #1937287)
-
-The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
-bare echo commands so that configure flags such as --quiet work
-correctly. (Addresses Sourceforge Patches: #2058794)
-
-A few uses of sprintf have been removed from the ext2fs library to
-make life easier for bootloaders with a limited libc environment.
-(Addresses Sourceforge Bug: #2049120)
-
-The ext2fs_read_inode() checks the validity of the inode number passed
-to it earlier, to avoid doing some needless work when it would fail
-anyway.
-
-The ext2fs_open() checks the validity of the blocksize parameter
-passed to it earlier, to avoid doing some needless work when it would
-fail anyway.
-
-Disable a very annoying automatic "%.sh -> %" GNU make rule in the
-top-level Makefile. That automatic rule is used to better support
-SCCS, but it caused problems for a particular niche distribution which
-likes to use configure.sh files to store the configure options used to
-build a package. Unfortuntaely GNU make will use the configure.sh to
-replace the configure script, resulting in a self-inflicted fork bomb
-leading to an out-of-memory crash.
-
-To support old GNU C compilers don't use C99/C++ comments, but only
-K&R style comments, and don't try to use __builtin_expect if __GNUC__
-is less than 3. (__builtin_expect is only supported for gcc versions
-2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
-this is an optimization, we only try to use __builtin_expect for gcc 3
-and up.)
-
-In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
-__LITTLE_ENDIAN, which are only defined by glibc's header files and
-hence isn't portable.
-
-For the convenience for some distributions that need a static tune2fs,
-the Makefile for misc/ now has a tune2fs.static target.
-
-The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
-for extent-based files
-
-The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
-files.
-
-All source files no longer have any trailing white space.
-
-The io_channel_read_blk64() and io_channel_write_blk64() functions are
-now functions instead of C preprocessor macros to provide better
-forward compatibility.
-
-The e2fpsrogs translation template now expands the @x abbrevation.
-
-Various namespace leackages in libblkid, libe2p, and libext2fs have
-been fixed.
-
-Fix a parallel build problem in e2fsprogs.
-
-E2fsprogs is now more portable to Solaris.
- * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
- are always present.
- * Scripts do not assume that /bin/true is always in /bin
- * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
- * Flush stdio handles before calling setbuf(), since Solaris will
- discard any pending output to the stream.
- * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
- picky about which C compiler can beused for SUSv3 conformance.
- Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
- and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
- Since we need some SUSv3 functions, consistently use SUSv3 so
- that e2fsprogs will build on Solaris using c99.
- * Solaris C99 does not support varargs C preprocessor macros
- * Solaris header files pollute the C namespace if in/netinet.h
- is included, which conflicts with e2fsprogs' use of the kmem_cache_t
- typedef.
- * Solaris ships with a pathetically ancient shell in /bin/sh so we
- avoid the use of various more avanced shell constructs such as $().
-
-The "make rpm" command will now take some extra configure optiosn from
-the build environment without needing to patch the source tree.
-
-The ext2fs_add_dir_block() function will now grow the dblist more
-aggressively as an optimization to avoid copying the array too often.
-
-The e2fsck_write_bitmaps() will write the block and inode bitmaps
-together instead of in two passes.
-
-
-E2fsprogs 1.41 (July 10, 2008)
-==============================
-
-Add support for ext4 filesystem features, in particular extents,
-uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
-support for checking journal checksums. Debugfs will print new
-superblock and inode fields that were defined for ext4. For example,
-the nanosecond and i_version fields of an inode, and the
-s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
-Note: Resize2fs doesn't currently support the combination of flex_bg
-and !resize_inode. (Addresses Debian Bug: #388452, #425477)
-
-Tune2fs can support migrating a filesystem from using 128 byte inodes
-to 256 byte inodes, so it can take advantage of the full features of
-ext4.
-
-Add support for "undo" support. E2fsck and mke2fs can optionally
-record an undo log which can replayed by the program e2undo.
-
-E2fsck could damage a filesystem by trying to relocate inode tables
-due to corrupted block group descriptors, where the attempted inode
-table relocation would do far more harm than good. E2fsck has been
-fixed to detect this these sorts of corrupted block group descriptors
-much earlier in e2fsck processing, so it can try to use the backup
-superblock and block group descriptors first. This should be a much
-better strategy for recovering these types of corrupted filesystems.
-(Addresses Sourceforge Bug: #1840291)
-
-E2fsck will display a more understandable message when the last check
-field in the superblock is in the future. (Addresses Debian Bug:
-#446005).
-
-E2fsck now performs more extensive and careful checks of extended
-attributes stored in the inode.
-
-Enhance mke2fs to print a more explanatory error message when
-ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
-#488663)
-
-Fix mke2fs to use a default block size of 4k when formatting an
-external journal device. This is done by using a fixed filesystem
-type list that consists only of the single filesystem type "journal"
-when looking up configuration keys in /etc/mke2fs.conf. (Addresses
-Debian Bug: #488663)
-
-Speed up how mke2fs writes the journal data blocks by writing the disk
-blocks in larger chunks.
-
-Fix blkid handling of stale devices. Fix a bug which could cause a
-core dump while garbage collecting the blkid cache, and assure that
-blkid_find_dev_with_tag() never returns a non-existent device. Also,
-if a filesystem is found at a new /dev location, eliminate any
-duplicate stale entries which can not be verified.
-(Addresses Debian Bugs: #487758, #487783)
-
-Add more paranoid checks for LVM volumes and swap partitions in
-blkid's probe function, to reduce the chances of false positives.
-
-The mke2fs program now has a much more sophisticated system for
-controlling configuration parameters of a newly created filesystem
-based on a split filesystem and usage type system. The -t option to
-mke2fs was a deprecated alias to -c; it now specifies a filesystem
-type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
-separated usage list. The filesystem type information and type
-information is used to extract configuration parameters from the
-/etc/mke2fs.conf file.
-
-The mke2fs program will no longer complain and request the -f option
-when the user tries to create a filesystem with greater than 2**31
-blocks.
-
-When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
-adjust the mke2fs.conf file so filesystems for the Hurd are created
-with a blocksize of 4096 and inode size of 128, which is all it knows
-how to handle. (Addresses Debian Bug: #471977)
-
-Mke2fs will always make sure that lost+found always has at least 2
-blocks, even for filesystems with very large blocksizes (i.e., 64kb).
-
-Resize2fs will now print the minimum needed filesystem size if given
-the -P option, and will resize the filesystem to the smallest possible
-size if given the -M option.
-
-Fix resize2fs to clean up the resize_inode if all of the reserved gdt
-blocks are consumed during an off-line resize.
-
-The "ls" command in debugfs now supports the -p option, which causes
-it to quote the filenames so that spaces or tabs in directory entries
-are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
-Sourceforge Feature Request: #1201667)
-
-Fix a potential off-by-one buffer oveflow in the fs_device_name in an
-e2image file.
-
-The chattr program will return a non-zero exit code in case of
-failures, and error messages can be suppressed with the -f option.
-(Addresses Red Hat Bugzilla: #180596)
-
-Fix a bug in badblocks which caused it to overrun an array and likely
-crash if more than 8 test patterns are specified using the -t option.
-(Addresses Debian Bug: #487298)
-
-Add support to badblocks to limit how quickly it reads from the disk
-drive (so it can be used for background scrubbing), and so it will
-abort after finding a given number of errors.
-
-Remove support for the legacy big-endian filesystem format which only
-existed on extremely long-dead PowerPC kernels almost a decade ago.
-
-Remove MASIX support from e2fsprogs.
-
-Add I/O statistics reporting to e2fsck.
-
-Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
-Czech translations.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs: #487443, #487675, #490003)
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages.
-(Addresses Debian Bugs: #393313, #487849, #440983, #440981)
-
-Programmer's Notes
-------------------
-
-Factor out bitmap code in preparation for adding 64-bit new-style
-bitmaps.
-
-Fix gcc -Wall warnings
-
-Fix the pkg-config files so that private librares are specified in
-"Libs.private:".
-
-Fix the libext2fs.texinfo manual so it builds with modern versions of
-texinfo.
-
-Silence the makefile from showing the awk command used to build the
-
-Clean up the badblocks group so to make it more portable and robust.
-
-Avoid using predictable filenames in /tmp in blkid's regression test
-suite. Also remove bashism's in the regression test script.
-
-If the configure script is given --with-diet-libc, don't use thread
-local storage, since diet libc doesn't support TLS. (Addresses
-Sourceforge Bug: #2000654)
-
-Fix the blkid regression test suite to tolerate older versions of
-mkswap that don't support the -U option.
-
-A few library routines have been converted to support 64-bit block
-numbers; in particular, the I/O manager functions, the test_io,
-inode_io, and unix_io managers have all be converted to support 64-bit
-operation.
-
-Debugfs can now be extended for use by test programs. See
-lib/ext2fs/extents.c for an example for how it can be used. The test
-program links against the debugfs object files, and provides
-additional commands by defining an auxiliary libss command table.
-
-The lazy_bg filesystem feature, which was only used by developer's
-testing, has been removed since it has been largely supplanted by
-uninit_bg. This also simplifies the code.
-
-
-E2fsprogs 1.40.11 (June 17, 2008)
-=================================
-
-Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
-percentage of reserved blocks. (Addresses Debian Bug: #452639)
-
-Updated Spanish and Catalan translations.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs: #483962, #483023)
-
-Add detection for ZFS volumes to the libblkid library.
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages.
-(Addresses Debian Bug: #486463)
-
-Programmer's notes:
--------------------
-
-Fix marginal C code in probe_lvm2() function to the blkid library more
-portable for older compilers.
-
-Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
-
-Fix ext2fs_swap{16,32,64} functions so they can be used by external
-applications on big-endian machines. (Addresses Debian Bug: #484879)
-
-
-E2fsprogs 1.40.10 (May 21, 2008)
-================================
-
-When deciding whether or not to revalidate a blkid cache entry, if the
-device's mtime is newer than the last time the cached entry was
-validated, force a revalidation.
-
-Fix a potential data corruption bug in e2fsck in the journal replay.
-The chances of this is happening is extremely remote, especially the
-default data=ordered or data=writeback modes. However, if a block
-which has been journalled starts with the first four bytes 0xc03b3998,
-when e2fsck replays the journal, those four bytes will be replaced
-with zero's. Fortunately, it is highly, highly unlikely for e2fsck
-metadata to begin with those fatal 4 byte sequence, and unless
-data=ordered mode is in use, data blocks are never journaled.
-
-Updated German, Dutch, Sweedish, and Vietnamese translations.
-
-Programmer's notes:
--------------------
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details.
-
-Remove default sizes of types when cross compiling, since autoconf
-2.50 can figure this out automatically now.
-
-
-E2fsprogs 1.40.9 (April 27, 2008)
-=================================
-
-SuSE's security team audited uuidd and came up with a few minor
-issues. None of them are serious given that uuidd runs setuid as a
-unprivileged user which has no special access other than libuuid
-directory, but it's good to get them fixed.
-
-One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
-work correctly with in-inode extended attributes.
-
-Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
-translations.
-
-Debugfs will avoid using a pager if the standard output is not a tty.
-
-Fix debugfs and tune2fs to correctly handle daylight savings time when
-parsing a time string.
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages.
-
-Fix fsck completion bars when multiple filesystems were being checked
-in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
-#203323, Addresses Sourceforge Bug: #1926023)
-
-Fix fsck so that progress information is sent back correctly when
-multiple filesystems are being check and the output of fsck is being
-redirected to a file descriptor. Also, include the device name (w/o
-spaces) in the progress information sent back via a file descriptor.
-(Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
-#1926023)
-
-Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
-
-If logsave receives a SIGTERM or SIGINT signal, it will now pass that
-signal to its child process.
-
-Fix mke2fs's creation of are resize inode when there is a non-standard
-s_first_data_block setting.
-
-Fix bug in blkid when run by an unprivileged user; most devices were
-not reported correctly. 9Addresses Launchpad Bug: #220275)
-
-Mke2fs will not allow the logically incorect combination of
-resize_inode and meta_bg, which had previously caused mke2fs to create
-a corrupt fileystem.
-
-Fix fsck in German locales so that a 'j' means yes.
-(Addresses Sourceforge Bug: #1947683)
-
-
-Programmer's notes:
--------------------
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details.
-
-Update valgrind options in test_script to work with valgrind 3.2.3
-
-Update texinfo.tex to a much newer version from the FSF.
-
-Remove bashism for configure script and from the lib/ss Makefile.
-Addresses Sourceforge Bug: 1921969
-
-Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
-
-Fix build system so that if texinfo is not installed, it won't print a
-(harmless) error message.
-
-
-E2fsprogs 1.40.8 (March 13, 2008)
-=================================
-
-Fixed e2image -I so it works on image files which are larger than 2GB.
-
-Fixed e2fsck's handling of directory inodes with a corrupt size field. If
-the size is larger than the number of blocks found in the inode, don't
-try to allocate extra empty blocks at the end of the directory to make
-up the difference; there's no point to doing that. In addition, if
-the size is not a multiple of a blocksize, always fix it.
-
-E2fsck handled a pass 2 "should never happen error" by not giving
-enough information and then core dumping. Unfortunately, it was all
-too easy to trigger the "should never happen" situation if a
-directory's inode size was not correct. This has been fixed, but
-e2fsck has also been taught how to handle this situation more
-gracefully, by simply removing the inode hash tree information, so
-that it can be rebuilt again after e2fsck's pass 3. (Addresses
-Launchpad Bug: #129395)
-
-Resize2fs had a bug resizing large inodes with extended attributes
-that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
-completely on big-endian systems such as PowerPC. The bug should be
-completely fixed now. Yay for regression test suites. (Addresses Red
-Hat Bugzilla: #434893)
-
-Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
-translations. Many thanks to Philipp Thomas from Novell for stepping
-up to become the new German translation maintainer! (Addresses Debian
-Bugs: #302512, #370247, #401092, #412882).
-
-When e2fsck is clearing a corrupt inode's HTREE directory information,
-make it clear that it is just clearing the HTREE information, not the
-entire inode.
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages.
-
-Programmer's notes
-------------------
-
-Add new functions, ext2fs_dblist_get_last() and
-ext2fs_dblist_drop_last(), which allows the caller to examine the last
-directory block entry added to the list, and to drop if it necessary.
-
-Fixed a portability problem in libblkid with DJGPP.
-
-Fix an obvious typo in an "internal error" message in e2fsck. Thanks
-to Philipp Thomas for pointing this out.
-
-If the info files are not built, change "make install" so it doesn't
-fail with an error code.
-
-
-E2fsprogs 1.40.7 (February 28, 2008)
-====================================
-
-Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
-depreciate the -s option, since it can result in filesystems which
-e2fsck can't fix easily. There are very good reasons for wanting to
-disable sparse_super; users who wants to turn off sparse_super can use
-debugfs. (Addresses Sourceforge Bug: #1840286)
-
-Add missing options to mke2fs's usage message. (Addresses Sourceforge
-Bug: #1751393)
-
-Fix bug in resize2fs when large (greater than 128 byte) inodes are
-moved when a filesystem is shrunk; it was only moving the first 128
-bytes, so extended attributes were not getting moved. (Addresses Red
-Hat Bugzilla: #434893)
-
-E2fsck now prints an explicit message when the bad block inode is
-updated, to avoid confusion about why the filesystem was modified.
-(Addresses Sourceforge Bug: #756460)
-
-Allow mke2fs and tune2fs manipulate the large_file feature.
-Previously we just let the kernel and e2fsck do this automatically,
-but e2fsck will no longer automatically clear the large_file feature.
-It still isn't really necessary to worry about this feature flag
-explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
-#258381)
-
-Suppress message about an old-style fstab if the fstab file is empty.
-(Addresses Debian Bug: #468176)
-
-Fix (really minor) bug in debugfs's find_free_block so it avoids
-reporting a free block more than once if there are too few free blocks
-in the filesystem. (Addresses Sourceforge Bug: #1096315)
-
-Change e2fsck to no longer clear the LARGE_FILES feature flag
-automatically, when there are no more > 2GB files in the filesystem.
-It's been almost a decade since there have been kernels that don't
-support this flag, and e2fsck clears it quietly without telling the
-user why the filesystem has been changed.
-
-Fix bug which could cause libblkid to seg fault if a device mapper
-volume disappears while it is being probed. (Addresses RedHat
-Bugzilla: #433857)
-
-Inhance e2fsck's reporting of unsupported filesystem feature flags.
-(Addresses Sourceforge Feature Request: #1175808)
-
-Fix option syntax in dumpe2fs for explicit superblock and blocksize
-parameters. What was currently documented in the man page has been
-broken for some time, due to getopt() implementation changes. The
-option sytax has been changed to one which is can be more portable
-supported and which is consistent with the format for extended options
-in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
-
-Add support to tune2fs to clear the resize_inode feature. This
-requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
-
-Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
-Bugzilla: #409321)
-
-Add support for setting RAID stride and stripe-width via mke2fs and
-tune2fs. Teach dumpe2fs to print the RAID parameters.
-
-Add support for setting new superblock fields to debugfs's
-set_super_value.
-
-Add support for printing "mostly-printable" extended attributes in
-Debugfs.
-
-Add support for the -M option to fsck, which causes it to ignore
-mounted filesystem.
-
-Fix uuidd so that it creates the pid file with the correct pid number.
-(Addresses Sourceforge Bug: #1893244)
-
-Fix various gcc -Wall warnings.
-
-Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages.
-(Addresses Sourceforge Patch: #1399325)
-
-
-Programmer's notes:
--------------------
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bug: #466929)
-
-Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
-partially filled-in filesystem object on an error, so that e2fsck can
-print more intelligent error messages.
-
-Add a new function e2p_edit_feature2() which allows the caller to
-specify which feature flags are OK to set or clear, and which returns
-more specific information about feature flags which are not allowed to
-be set/cleared.
-
-Set the C locale in the test_script driver since it uses [A-Za-z].
-(Addresses Sourceforge Bug: #1890526)
-
-Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
-support lockf().
-
-Change configure.in to avoid using the 'dc' command unless it is
-absolutely needed. (i.e., when using parsing a WIP-style version
-number) (Addresses Sourceforge Bug: #1893024)
-
-Add portability checks to support compilation under DJGPP.
-
-Update to the latest samba tdb code before the LGPLv3 change, which
-fixes a realloc() leak on failure.
-
-Fix memory leak in ext2fs_alloc_block().
-
-Fix makefile dependency issues for various install targets.
-(Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)
-
-Improve descriptions for the r_move_itable and r_resize_inode tests.
-
-
-E2fsprogs 1.40.6 (February 9, 2008)
-===================================
-
-Add support for returning labels for UDF filesystems in the blkid
-library.
-
-Fix bug in the blkid library where cached filesystems was not being
-flushed when opening USB devices returned the error ENOMEDIUM.
-(Addresses Debian Bug: #463787)
-
-Added logic to the blkid library to automatically choose whether a
-filesystem should be mounted as ext4 or ext4dev, as appropriate.
-
-Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
-
-Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
-configured with --enable-jbd-debug.
-
-Document the BLKID_FILE environment variable in the libblkid man page
-
-Programmer's Notes:
--------------------
-
-Update e2fsprogs translation template and Vietnamese and Czech translations
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs: #436058)
-
-Don't try to create $DESTDIR/etc/init.d as part of make install as we
-don't install the init.d script (and it's not the recommended way to
-start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
-
-Use thread local storage to fix a theoretical race condition if two
-threads try to format an unknown error code at the same time in the
-com_err library.
-
-
-E2fsprogs 1.40.5 (January 27, 2008)
-===================================
-
-Fix a potential overflow big in e2image if the device name is too
-long.
-
-Mke2fs will now create new filesystems with 256 byte inodes and the
-ext_attr feature flag by default. This allows for much better future
-compatibity with ext4 and speeds up extended attributes even on ext3
-filesystems.
-
-Teach e2fsck to ignore certain "safe" filesystem features which are
-set automatically by the kernel. Having the kernel set features
-automagically behind the user's back is a bad idea, and we should try
-to break the kernel of this habit, especially for the newer ext4
-feature flags. But for now, we will try to avoid needless full checks
-which can annoy users who are doing fresh installs.
-
-Add support in tune2fs and mke2fs for making a filesystem as being "ok
-to be used with test kernel code". This will be needed for using test
-filesystems with the latest ext4 kernel code.
-
-Change e2fsck -fD so that it sorts non-htree directories by inode
-numbers instead of by name, since that optimizes performances much
-more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
-
-If e2image fills the disk, fix it so it exits right away instead of
-spewing large numbers of error messages.
-(Addresses-Sourceforge-Feature-Request: #606508)
-
-If ftruncate64() is not available for resize2fs, let it use ftrucate()
-instead, but have it check to see if the size would get truncated, and
-skip calling ftruncate in that case.
-
-Add support for detecting HFS+ filesystems in the blkid library.
-
-Add supprt in the blkid library for ext4/ext4dev filesystems.
-
-Fix a bug in blkid where it could die on a floating point exception
-when presented with a corrupt reiserfs image.
-
-Fix blkid's handling of ntfs UUID's so that leading zeros are printed
-such that UUID string is a fixed length.
-
-Add sample python bindings for the uuid library to the contrib
-directory. (Addresses-Sourceforge-Patches: #778817)
-
-Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
-will work with large files. (Addresses Sourceforge Feature Request:
-#1257500 and Sourceforge Support Request: #1253511)
-
-Allow the debugfs 'undel' command to undelete an inode without linking
-it to a specific destination directory, since this might require
-allocating blocks that could overwrite some yet-to-be-recovered
-deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
-
-Update Swedish translations from the Translation Project.
-
-Programmer's Notes:
--------------------
-
-Fix configure handling of --sbindir (which should rarely be used, but
-someone did complain, so let's fix it). (Addresses Sourceforge Bug:
-#498381)
-
-Updated e2fsprogs.spec file to include a new uuidd package
-
-Use pkg-config to determine where to find the devmapper library so we
-can find out where it is located on different distributions.
-
-Fix Makefile race so that "make -j3 distclean" works correctly
-
-Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
-especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
-#1819034, #1863819)
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs: #459403, #459475, #459614)
-
-Remove the --enable-dynamic-static configure option, and build e2fsck
-dynamically by default. If the user wants e2fsck.static, he/she will
-need to build it via "make -C e2fsck e2fsck.static"
-
-Fix various build warnings due to missing prototypes.
-(Addresses Sourceforge Patch: #1861663, #1861659)

-
-E2fsprogs 1.40.4 (December 31, 2007)
-====================================
-
-Improve time-based UUID generation. A new daemon uuidd, is started
-automatically by libuuid if necessary. This daemon is setuid to allow
-updates to /var/lib/libuuid, so the clock sequence number can be
-stored and so if the clock is set backwards, it can be detected.
-(Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
-#233471)
-
-Filter out the NEEDS_RECOVERY feature flag when writing out the backup
-superblocks. This avoids e2fsck from concluding that a full
-filesystem check is required before backing up the superblock due to
-changes in the feature flags. (Addresses Debian Bug: #454926)
-
-Fix fsck to only treat the '#' character as a comment at the beginning
-of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
-will cause fsck to issue an bogus warning message.
-(Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
-
-Format control characters and characters with the high eighth bit set
-when printing the contents of the blkid cache, to prevent filesystems
-with garbage labels from sending escape sequences to the user's screen
-that might, for example place it in graphics mode. (Addresses Ubuntu
-Bug: #78087)
-
-Fix sign-extension problem on 64-bit systems in in the com_err
-library. (Addresses Sourceforge Bug: #1809658)
-
-Avoid division by zero error when probing an invalid FAT filesystem in
-the blkid library. (Addresses Sourceforge Bug: #1831627)
-
-Update Dutch, Polish, and Vietnamese translations from the Translation
-Project. Remove the Rwandan translation upon advice of the
-Translation Project.
-
-Programmer's Notes:

-
-E2fsprogs 1.40.3 (December 5, 2007)
-===================================
-
-Fix a potential security vulnerability where an untrusted filesystem
-can be corrupted in such a way that a program using libext2fs will
-allocate a buffer which is far too small. This can lead to either a
-crash or potentially a heap-based buffer overflow crash. No known
-exploits exist, but main concern is where an untrusted user who
-possesses privileged access in a guest Xen environment could corrupt a
-filesystem which is then accessed by the pygrub program, running as
-root in the dom0 host environment, thus allowing the untrusted user to
-gain privileged access in the host OS. Thanks to the McAfee AVERT
-Research group for reporting this issue. (Addresses CVE-2007-5497.)
-
-Fix hueristics in blkid which could cause a disk without partitions to
-be incorrectly skipped when a loopback device is present. (Addresses
-Red Hat Bugzilla #400321.)
-
-Fix e2image so that in raw mode it does not create an image file which
-is one byte too large.
-
-Change mke2fs's usage message so it recommends the preferred -E option
-instead of the deprecated -R option.
-
-Enhance the blkid library so it will recognize squashfs filesystems.
-(Addresses Red Hat Bugzilla #305151.)
-
-Enhance e2fsck so it will force the backup superblocks to be backed up
-if the filesystem is consistent and key constants have been changed
-(i.e., by an on-line resize) or by e2fsck in the course of its
-operations.
-
-Enhance blkid's detection of FAT filesystems; so that USB disks with
-only a single bootable partition will not get missed.
-
-E2fsck will no longer mark a filesystem as invalid if it has time
-errors (i.e., if superblock mount time or last write time is in the
-future) and the user refuses to fix the problem.
-
-The Ubuntu init scripts don't properly set the system time correctly
-from hardware clock if the hardware clock is configured to tick local
-time instead of GMT time. Work around this as best as we can by
-providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
-be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
-Bug #131201.)
-
-Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
-Hat Bugzilla #151533.)
-
-Fix e2fsck so that if the superblock is corrupt, but still looks
-vaguely like an ext2/3/4 superblock, that it automatically tries to
-fall back to the backup superblock, instead of failing with a hard
-error.
-
-Make the e2fsprogs program more robust so that they will not crash
-when opening a corrupt filesystem where s_inode_size is zero.
-
-Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
-arguments are detected as such and the parse error is reported to the
-user. (Addresses Debian Bug #435381.)
-
-Change e2fsck so it will not complain if a file has blocks reallocated
-up to the next multiple of a system's page size.
-
-Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
-about (valid) filesystems where the inode table extends to the last
-block of the block group. (Addresses Red Hat Bugzilla #214765.)
-
-Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
-allocating inode tables for some relatively rare odd disk sizes.
-(Addresses Red Hat Bugzilla #241767.)
-
-Add Catalan translation and update Dutch and Swedish translations
-from the Translation Project.
-
-Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
-still had an issue when trying to figure out whether we need to
-byte-swap fast symlinks that contained extended attributes.
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages.
-(Addresses SourceForge Bug #1821333.)
-
-
-Programmer's Notes:
--------------------
-
-Fix mke2fs tests to avoid needing any significant ^M (CR) characters
-
-Add "make check" to the RPM spec file
-
-Fix "make install" and 'make unstall" in misc/Makefile.in so that it
-works correctly when the prefix is not the root directory.
-
-Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
-clena up after themselves by deleting the test.img temporary file
-after completing the test.
-
-Fixed a corner case bug ext2fs_unlink() when trying to delete the
-first directory entry in a directory block and the last directory
-entry in the previous directory block is not in use. Fortunately
-ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
-places where it is extremely unlikely to run into this corner case.
-
-Fix missing dependency which would cuase parallel builds to fail.
-(Addresses Sourceforge Bug #1842331.)
-
-Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
-calling open(O_CREATE) with a missing mode parameter.
-
-Fix the test_ss.c in lib/ss so it can be used as an example
-application program for the library as well as a regression test
-suite.
-
-Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
-are properly passed back up through the call stack.
-
-E2fsprogs 1.40.2 (July 12, 2007)
-================================
-
-A recent change to e2fsck_add_dir_info() to use tdb files to check
-filesystems with a very large number of filesystems had a typo which
-caused us to resize the wrong data structure. This would cause a
-array overrun leading to malloc pointer corruptions and segfaults.
-Since we normally can very accurately predict how big the the dirinfo
-array needs to be, this bug only got triggered on very badly corrupted
-filesystems.
-
-Fix a bug in e2fsck which caused it to incorrectly salvange
-directories when the last entry's rec_len is bogusly too big. This
-resulted in a nonsense filesystem corruption to be reported, and
-required a second run of e2fsck to fully fix up the directory.
-
-Update tune2fs man page to include more discussion of reserved blocks
-(Addresses Launchpad bug #47817)
-
-Update Turkish, Polish, Dutch, and Vietnamese PO files from the
-Translation Project
-
-
-E2fsprogs 1.40.1 (July 7, 2007)
-===============================
-
-Fix bug which could cause libblkid to loop forever. When revalidating
-a partition where there is obsolete information in /etc/blkid.tab, we
-end up freeing a the type tag without clearing dev->bid_type, causing
-blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
-
-The Turkish translation has a bug in it where it has the translation
-of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
-@E, recursively, forever, until the stack fills up and e2fsck core
-dumps. We fix this by making e2fsck stop @-expansions after a
-recursive depth of 10, which is far more than we need.
-(Addresses Sourceforge Bug: #1646081)
-
-Compile the default mke2fs.conf into mke2fs program. People are
-getting surprised by mke2fs creating filesystems with different
-defaults than earlier versions of mke2fs if mke2fs.conf is not
-present. So we now create a built in version of mke2fs.conf file
-which is used by mke2fs if the /etc/mke2fs.conf is not present.
-(Addresses SourceforgeBug: #1745818)
-
-Improve the config/parse_types.sh helper script. Fix a potential
-security problem if e2fsprogs is built as root (as Gentoo does!). In
-addition fix the script and how it is called from the configure script
-so that it does the right thing when cross-compiling. (Fixes Gentoo
-bug: #146903)
-
-Update Vietnamese, French, and Dutch PO files from the Translation
-Project. Also created a new e2fsprogs.pot file for translator.
-
-Fix bogus strip permission errors when building under Debian. When
-building the e2fsprogs dpkg's, the dh_strip command emits a large
-number of error messages caused by the permissions not being right.
-So run dh_fixperms before running dh_strip.
-
-Programmer's Notes:
--------------------
-
-Add new function: profile_set_default(). This function sets the value
-of the pseudo file "<default>". If the file "<default>" had
-previously been passed to profile_init(), then def_string parameter
-will be parsed and used as the profile information for the "<default>"
-file.
-
-Fix mk_cmds's error reporting so that it is unambiguous that it is the
-mk_cmds script which is generating the error. (Obviates Gentoo patch:
-e2fsprogs-1.32-mk_cmds-cosmetic.patch)
-
-Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
-priority" environment variable that overrides all others, where as
-LANG is the lowest priorty environment variable. If LC_ALL is set, it
-doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
-the all the rest are set. This will assure that the locale when
-running the test suites is the "C" locale. (Obviates Gentoo patch:
-e2fsprogs-1.38-tests-locale.patch)
-
-
-E2fsprogs 1.40 (June 29, 2007)
-==============================
-
-Fix divide by zero error in blkid's NTFS probing logic.
-
-Add new blkid -g option which causes the blkid cache to be garbage
-collected.
-
-Fix a bug in libblkid which could cause the internal field bid_type to
-become corrupted. Fortunately bid_type isn't used much, and bid_label
-and bid_uuid is only used by debugging code, so the impact of this bug
-was very minor.
-
-Mke2fs will now store the RAID stride value when a filesystem is
-created with a requested RAID stride, and then use it automatically in
-resize2fs.
-
-Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
-isn't too big. In some cases Lustre users have tried specifying an
-inode size of 4096 bytes, while keeping an inode ratio of one inode
-per 4096 bytes.
-
-Improve sanity check in e2fsck's algorithm for finding a backup
-superblock, so that it won't accidentally find a superblock that was
-located in the journal, and then later reject it as being not a valid
-backup superblock.
-
-Fix e2fsck get_size logic so that it will work with the Linux floppy
-driver. The Linux floppy driver is a bit different from the other
-block device drivers, in that if the device has been opened with
-O_EXCL, it disallows another open(), even if the second open() does
-not have the O_EXCL flag. (Addresses Debian Bug: #410569)
-
-Fix error checking of badblock's last-block and start-block arguments.
-(Addresses Debian Bug: #416477)
-
-Fix e2fsck so that it doesn't overwrite the backup superblocks when
-recovering a journal until the master superblock has been confirmed as
-being sane.
-
-Change the blkid library to be much more paranoid about concluding
-that a partition contains an NTFS filesystem, and fetch the UUID and
-LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
-#110138)
-
-Factor out the code which sets the default journal size and move it
-into libext2fs.
-
-Enhance e2fsck so it will recreate the ext3 journal if the original
-journal inode was cleared to due it being corrupt after finishing the
-filesystem check.
-
-Fix e2fsck so that it updates the journal inode if it is corrupted and
-the backup journal information from the superblock was successfully
-used to recover the filesystem.
-
-Fix e2fsck so that it checks all of the blocks in the journal inode
-for validity. The original code only checked the direct blocks to
-make sure the journal inode was sane. Unfortunately, if some or all
-of the indirect or doubly indirect blocks were corrupted, this would
-not be caught.
-
-Add support in blkid to detect LUKS encrypted partitions.
-
-Add extra sanity checks for extended attributes in the case where the
-size is zero but the offset is very large.
-
-Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
-and ext2fs_get_next_inode_full().
-
-Clarify the copyright licenses used by the various libraries in
-the top-level COPYING file (Red Hat Bugzilla: 166058)
-
-Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
-
-Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
-
-Remove check in e2fsck which requires EA's in inodes to be sorted;
-they don't need to be sorted, and e2fsck was previously wrongly
-clearing unsorted EA's stored in the inode structure.
-
-Allow mke2fs or tune2fs to create a substantially larger journal (up
-to 10,240,000 blocks).
-
-Fix MD superblock detection, and make sure the correct UUID is
-reported from the MD superblock.
-
-Fix a signed vs. unsigned bug in debugfs.
-
-Enhance debugfs's date parser so that it accepts integer values.
-
-Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
-file with multiply claimed blocks is hard linked. or not at all if the
-root directory contains shared blocks
-
-Enhance debugfs so it can modify the block group descriptors using the
-command set_block_group_descriptor.
-
-Improve e2fsck's reporting of I/O errors so it's clearer what it was
-trying to do when an error happens
-
-Fix a bug in in how e2fsprogs byte swaps inodes containing fast
-symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
-#232663 and LTC Bugzilla: #27634)
-
-Fix potential file descriptor leak in ext2fs_get_device_size() in an
-error case.
-
-Add libreadline.so.5 support to libss.
-
-Impove badblocks -n/-w exclusive usage message.
-
-Fix dump_unused segfault in debugfs when a filesystem is not open
-
-Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
-
-Allow the debugfs lcd command to work w/o a filesystem being open.
-(Addresses LTC Bugzilla #27513)
-
-Fix e2fsck to clear i_size for special devices with a bogus i_blocks
-field on the first pass.
-
-Fix e2fsck to set the file type of the '..' entry when connecting
-a directory to lost+found. (Addresses Lustre Bug: #11645)
-
-Enhance e2fsck to recover directories whose modes field were corrupted
-to look like special files. This is probably only useful in
-artificial test cases, but it will be useful if we ever do the "inodes
-in directory" idea for ext4.
-
-Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
-#412614)
-
-Fix resize2fs parsing of size parameter (in sector units). This was
-actually a bug in libe2p's parse_num_blocks() function. When handling
-the 's' suffix, it was ignoring the blocksize information passed in
-from the caller and always interpreting the number in terms of a 1k
-blocksize. (Addresses Debian Bug: #408298)
-
-There was a floating point precision error which could cause e2fsck to
-loop forever on really big filesystems with a large inode count.
-(Addresses Debian Bug: #411838)
-
-Fix memory leak in ext2fs_write_new_inode()
-
-Add support for using a scratch files directory to reduce e2fsck's
-memory utilization on really big filesystems. This uses the TDB
-library. See the [scratch_files] section of the e2fsck.conf man page
-for more details.
-
-Fixed type-punning bug which caused dumpe2fs to crash on the Arm
-platform (Addresses Debian Bug: #397044)
-
-Add explanatory message to badblocks that -n and -w are mutually exclusive
-(Addresses Debian Bug: #371869)
-
-Allow debugfs and dumpe2fs to support fs features under development.
-
-Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
-ext2fs_open() , which allows application to open filesystes with features
-which are currently only partially supported by e2fsprogs.
-
-Allow unix_io to support offsets greater than 2G (Addresses
-SourceForge Bug: #1547922)
-
-Fixed overflow and signed/unsigned problems caused by the number of
-blocks or inodes exceeding 2**31 or being close to 2**32-1.
-
-Add support for unsigned directory hash calculations with hints in the
-superblock to fix cross-architectural portability for htree
-directories with filenames where the high 8th bit is set. (Addresses
-Debian: #389772)
-
-Fix resize2fs so that it gives user-intelligible error messages if the
-filesystem or the kernel does not support on-line resizing.
-(Addresses Debian Bug: #380548)
-
-Require mke2fs -F -F for really dangerous operations, since -F is
-needed for less dangerous operations such as creating filesystems
-images in regular files, or creating filesystems on whole block
-devices. These relatively innocuous usages should NOT be confused
-with running mke2fs on an apparently-mounted or in-use filesystem.
-
-Allow the default inode size to be specified into the mke2fs.conf
-file.
-
-Make the smallest default journal size is big enough so that on-line
-resizing should always work.
-
-Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
-#1531372)
-
-Fix debugfs coredump when lsdel is run without an open filesystem
-(Addresses Debian Bug: #378335)
-
-Fix debugfs display bug us that bytes that have the high bit set are
-displayed as "ec" instead of "ffffffec".
-
-Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
-
-Device mapper scanning wasn't working in the blkid library because the
-pathnames had an extra "/dev" when they were being probed.
-
-Add GFS/GFS2 support to the blkid library.
-
-Fix blkid support of empty FAT filesystem labels.
-
-Avoid recursing forever (or for a long time) when the blkid library
-searches for a device and there are symlinks to directories in /dev.
-
-Avoid unaligned halfword access in blkid when accessing FAT
-superblocks, as this will cause Sparc/Solaris systems to throw a
-SIGBUS error.
-
-The latest devmapper libraries requires pthreads, add -lpthreads to
-the static link libraries for e2fsck.static if devmapper is enabled.
-(Addresses Debian bug: #388718)
-
-Improve the (non-installed, for experts only) findsuper program by
-printing the uuid and label from the superblocks, as well as the
-starting and ending offsets of the filesystem given the information in
-the superblock. Omit by default printing superblocks that are likely
-found in located in an ext3 journal unless an explicit -j option is
-given.
-
-Updated Spanish, French and Dutch translations and added Catalan
-translation. (Addresses Debian bug: #411562)
-
-Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
-determining a partition's size, since binary searching to determine
-the device doesn't work on FreeBSD.
-
-Documentation about UUID's is available in enough places, and it's
-awkward to deal with debian-legal's insanities. So I'm caving in the
-"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
-don't have do the dfsg tarball. Also remove the rule that only tried
-to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
-e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
-
-Fix the info-dir line so that the menu name does not contain a .info
-prefix. First of all, it's ugly, secondly, it causes the install-info
-command to fail to remove the com_err info file from the
-/usr/share/info/dir file when the comerr-dev package is removed and
-purged. (Addresses Debian Bug: #401711)
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages.
-(Addresses Debian Bug: #369761, #373004, #379695)
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs #389554, #390664, #413208, #419605,
-#408352, #415560, #399155)
-
-
-Programmer's notes:
--------------------
-
-E2fsck now supports the %It expansion when printing a problem report.
-It will print the type of the inode in the problem context.
-
-Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
-(Addresses Sourceforge Bug: #1565561)
-
-Remove unused variables and other lint/gcc -Wall cleanups
-
-Add check to ext2fs_get_device_size() so it will return EFBIG for for
-filesystems contained in regular files where the filesystem image size
-is returned by stat64().
-
-Set local environment variables to C so mk_cmds and compile_et always
-work. (Addresses SourceForge Bug: #1532177)
-
-Added the 64-bit byte swapping function ext2fs_swab64().
-
-Added two new helper functions to prevent 2**31/2**32-1 overflow
-problems: ext2fs_div_ceil() and e2p_percent().
-
-Create new ext2fs library inline functions ext2fs_group_first_block()
-and ext2fs_group_last_block() in order to calculate the starting and
-ending blocks in a block group.
-
-Create the generated files read-only to remind developers not to edit them.
-
-Add support for autoconf 2.60 (with backwards compatibility for older
-versions of autoconf).
-
-Added an "make rpm" target to top-level Makefile
-
-Added various FreeBSD portability fixes.
-
-Exclude mercurial files from the RPM build tree to speed up copy/build.
-
-Use root_sysconfdir to define the locations of mke2fs.conf and
-e2fsck.conf instead of using a hard-coded /etc pathname.
-
-Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
-
-Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
-
-If diff -u is supported, use it to report test failures.
-
-Updates/improvements to RPM spec file
-
-Add on-disk format definitions for the following new features:
-EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
-EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
-EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
-
-Add a new make target "checked-failed" in the tests directory which
-reruns any failed tests
-
-Update draft-leach-uuids-guids-01.txt with rfc4122.txt
-
-Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
-pointer dereferences, memory leaks, etc. None were security-criticial
-problems.
-
-Fix up usage and decrement error messages in the test_icount program
-
-Add debugging code to the com_err library; if the environment variable
-COMERR_DEBUG is set to 1, print out debugging messages as error tables
-are added and removed from the com_err library. If the
-COMERR_DEBUG_FILE environment variable is set (and the process is not
-setuid) the debugging messages may be redirected to a file.
-
-Change all of the e2fsprogs programs to use the newer add_error_table()
-and remove_error_table() interfaces instead of the much older
-initialize_*_error_table() function.
-
-Add TDB support into the ext2fs library. This allows us to have a
-guaranteed library we can count on always being present so we can
-store data in an on-disk database.
-
-Add support for using TDB to store the icount data, so we don't run out
-of memory when checking really large filesystems.
-
-Change the regression test suite so that it skips empty test directories.
-
-Define the l_i_iversion field in ext2_inode. The l_i_version field is
-now defined from the old l_i_reserved1 field in the ext2 inode. This
-field will be used to store high 32 bits of the 64-bit inode version
-number.
-
-Add Makefile production rule for e2fsprogs.spec in case it gets
-deleted.
-
-Add new function profile_get_uint() to allow for a clean way to fetch
-unsigned integers from the context.
-
-Add test to make sure the ext2 superblock structure is 1024 bytes.
-
-Fix typo in name of f_dup4 regression test
-
-Add new function blkid_gc_cache() which performs a garbage collection
-pass on the /etc/blkid.tab file.
-
-The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
-general, only e2fsck (after the filesystem is clean), tune2fs, and
-resize2fs should change the backup superblocks by default. Most
-callers of ext2fs_open() should not be touching any superblock fields
-which require the backups to be touched.
-
-Add new function to libext2fs, ext2fs_default_journal_size(), which
-returns the default journal size.
-
-
-E2fsprogs 1.39 (May 29, 2006)
-=============================
-
-Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
-between 2**31 and 2**32 blocks.
-
-Change mke2fs to use /etc/mke2fs.conf as a configuration file to
-configure the filesystem features, blocksize, and inode_ratio for
-different filesystem types.
-
-Mke2fs will now create filesystems hash trees and on-line resizing
-enabled by default, based on the new /etc/mke2fs.conf file.
-
-The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
-filesystem device node in exclusive mode to prevent accidents by
-system administrators. In the case of resize2fs and mke2fs, it will
-only use exclusive mode if the filesystem is not mounted.
-
-Fixed a bug in mke2fs which caused it to to fail when creating the
-resize inode for large filesystems. (Addresses Debian Bug #346580)
-
-When allocating space for the RAID filesystems with the stride
-parameter, mke2fs will now place each portion of the group's inode
-table right up after the superblock (if present) in order to minimize
-fragmentation of the freespace.
-
-Speed up mke2fs and e2fsck by writing inode and block bitmaps more
-efficiently by writing the inode and block bitmaps in one pass, thus
-reducing the number of disk seeks required.
-
-Add support for on-line resizing to resize2fs.
-
-Fix blkid library so that logic to determine whether or not a device's
-cached information in /etc/blkid.tab needs to be verified or not
-doesn't get confused by a system clock which is insane (for example,
-if the battery is dead on a Macintosh running PPC Linux. (Addresses
-Red Hat Bug: #182188)
-
-The blkid library will now store the UUID of the external journal used
-by ext3 filesystems, so that in the future, the userspace mount binary
-can use this to find the location of the external journal and pass
-this information to the kernel.
-
-E2fsck will now consult a configuration file, /etc/e2fsck.conf to
-control how various options should be handled. See the e2fsck.conf
-man page for more details. (Addresses Debian Bug: #150295)
-
-E2fsck now prints an explanatory message when delaying a filesystem
-check when the system is running on battery. (Addresses Debian Bug:
-#350306)
-
-E2fsck will detect if the superblock's last mount field or last write
-field is in the future, and offer to fix if so. (Addresses Debian Bug
-#327580) These problems will be fixed automatically in preen mode
-since Debian's boot sequence bogusly doesn't set the time correctly
-until potentially very late in the bootup process, and this can cause
-false positives which will cause users' systems to fail to boot.
-(Addresses Debian Bugs #343662 and #343645)
-
-E2fsck now checks to see if the superblock hint for the location of
-the external journal is incorrect, and if so, offer to update it.
-(Addresses Debian Bug: #355644)
-
-Fix e2fsck from segfaulting on disconnected inodes that contain one or
-more extended attributes. (Addresses Debian Bug: #316736, #318463)
-
-E2fsck will stop and print a warning if the user tries running a
-read/write badblocks test on a read-only mounted root filesystem.
-
-Fix a memory leak in e2fsck's error paths. (Thanks to Michael
-C. Thompson for pointing these out; they were originally found using
-Coverity.)
-
-When resizing a file containing a filesystem, resize2fs will expand or
-truncate a file as necessary. (Addresses Debian Bug: #271607)
-
-Resize2fs will now automatically determine the RAID stride parameter that
-had been used to create the filesystem, and use that for newly created
-block groups. The RAID stride parameter may also be manually specified
-on the command line using the new -S option to resize2fs.
-
-Fix mke2fs so that it correctly creates external journals on
-big-endian machines (such as a S/390).
-
-Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
-fail to print out the journal or hash seed UUID. (Thanks to Guillaume
-Chambraud for pointing this out.)
-
-Dumpe2fs will now print the size of the journal (if present).
-
-Fix debugfs's set_inode_field command so it can properly set the frag,
-fsize, uid_high, gid_high, and author fields in the inode instead of
-silently failing, and so that setting the i_size actually sets i_size
-correctly.
-
-Add a new debugfs command, set_current_time, which sets fs->now so
-that regression test suites can repeatedly modify the filesystem's
-last_write fields.
-
-Fix a bug in debugfs's icheck which would incorrectly report the owner
-of an extended attribute block.
-
-Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
-print a usage message when an illegal option character is given.
-
-Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
-so it won't core dump. (Addresses SourceForge bug #1424311)
-
-Fix mklost+found so that it creates a full-sized directory on
-filesystems with larger block sizes.
-
-Fix a file descriptor leak in blkid library.
-
-Fix a display bug in "badblocks -sv" so that the done message properly
-clears the block number at the end of the test. (Addresses Debian Bug
-#322231)
-
-Allow fractional percentages to the -m option in mke2fs and tune2fs
-(Addresses Debian Bug: #80205)
-
-Use fstat/fstat64 in getsize.c if the the target is a regular file,
-instead of attempting to do a binary search. Fix some fd leaks in
-error cases.
-
-Add support for device mapper library to the blkid library to ensure
-that the "best" (i.e., leaf) device is probed by the blkid library.
-
-Fix the blkid library so that it notices when an ext2 filesystem is
-upgraded to ext3.
-
-Improve the blkid's library VFAT/FAT detection; it now understands
-labels stored in the root directory, and is more paranoid about
-checking the FAT superblock values.
-
-Fixed a fd leak in the uuid library which was causing problems for the
-LVM tools. (Addresses Debian Bug: #345832)
-
-Add support for the reiser4 and software suspend partitions to the
-blkid library. Also add support for extract the label from iso9660
-filesystems.
-
-Fix a compile_et bug which miscount the number of error messages if
-continuations are used in the .et file.
-
-Add extra sanity checks to protect users from unusual cirucmstances
-where /etc/mtab may not be sane, by checking to see if the device is
-reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
-#319002)
-
-Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
-Bug: #343149, #341911, #300871, #316604, #316782, #330789)
-
-Fix use-after-free bug in e2fsck when finishing up the use of the
-e2fsck context structure.
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages and
-documentation. (Addresses Debian Bugs: #329859, #322188, #316811,
-#312515, #351268, #357951, #347295, #316040, #368392, #368393, #368394,
-#368179)
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs #317862, #320389, #290429, #310950,
-#310428, #330737, #330736, #329074, #356293, #360046, #366017, #364516,
-#362544, #362970)
-
-
-Programmer's notes:
--------------------
-
-Update config.guess and config.sub to latest version (2006-02-23) from
-FSF.
-
-Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
-Bugs: #360661, #360317)
-
-Fixed the Makefile so that they work correctly on newer versions of
-GNU make (i.e., 3.81).
-
-Add valgrind support to the regression test suites, and eliminate
-false positives from valgrind.
-
-Add a regression test suite for the blkid library.
-
-Fix a fencepost error in resize2fs caught by valgrind.
-
-Fix compiler warnings about missing memcpy prototypes.
-
-We no longer have the sparc assembly code in the header file any more,
-so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
-break compiles on the sparc architectures when using gcc.
-
-In the libext2fs library, add the new field fs->now which if non-zero
-is used instead of the system time when setting various filesystem
-fields (last modified time, last write time, etc.)
-
-Fix gcc 4.01 complaints by adding a missing #include <string.h> to
-ext2fs.h which is needed since the inline functions use memcpy().
-(Addresses Sourceforge Bug #1251062)
-
-Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
-the build system when building files in the util directory which are
-needed during the build process. This avoids potential problems when
-cross-compiling and some of the options specified in CFLAGS or LDFLAGS
-are not recognized as valid by the host compiler. (Addresses
-Sourceforge Bug #1261547)
-
-Clean up the blkid library by making the superblock and generic i/o
-functions to be more generic. Clean up interface to the probe
-function, and fix memory leak. Finallly, remove an unneeded reference
-to probe.h in the lib/blkid/resolve.c
-
-Add an ext2fs_read_bb_FILE regression test to confirm proper detection
-of invalid block #'s.
-
-The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
-indicate that the the function read/writes the memory location.
-
-Fix various gcc -Wall complaints.
-
-Add a dependency to make sure that the subdirectories are created
-before creating all of the object files, in order to address parallel
-build problem in the library Makefiles. (Addresses Sourceforge Bug:
-#1261553)
-
-Add $(LDFLAGS) to the command line argument when generating an ELF or
-Solaris shared library, to allow cross-compile and other builds that
-might need to specify -L paths to needed libraries. (Addresses
-Sourceforge Bug #1261549)
-
-Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
-intended for testing purposes. It allows an ext2/ext3 developer to
-create very large filesystems using sparse files where most of the
-block groups are not initialized and so do not require much disk
-space. Eventually it could be used as a way of speeding up mke2fs and
-e2fsck for large filesystem, but that would be best done by adding an
-RO_COMPAT extension to the filesystem to allow the inode table to be
-lazily initialized on a per-block basis, instead of being entirely
-initialized or entirely unused on a per-blockgroup basis.
-
-Fix backwards compatibility so e2fsprogs will better compile on Linux
-2.0.35 systems.
-
-Make test scripts more robust against locale-related environment variables
-
-Fix type warning problem with sizeof() in ext2fs_open2().
-
-Fix type warning problem with time_t in debugfs.
-
-
-E2fsprogs 1.38 (June 30, 2005)
-==============================
-
-Fix blkid's test programs (built with "make check") compile correctly
-even without "configure --enable-blkid-debug".
-
-Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
-type aliasing rules on newer gcc compilers. (Addresses Red Hat
-Bugzilla ##161183.)
-
-Fix com_err library to make it more compatible with recent changes
-made to the com_err library in MIT Kerberos V5 version 1.4.
-(Addresses Sourcefroge Bug #1150146)
-
-General cleanup of messages printed by e2fsprogs programs for grammar,
-consistency, and to make life easier for translators. Fixed a few
-strings containing English that had not been marked as needing
-translations. Removed strings that do not need to be translated, to
-make life easier for translators.
-
-Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
-test to see if a device appears to be in use instead of just relying
-on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
-
-Fix portability problem in the filefrag program affecting platforms
-where the size of an integer is smaller than the size of a long.
-(Addresses Debian Bug #309655)
-
-Mke2fs will now use a larger journal by default for filesystems
-greater than 4GB. (128 MB instead of 32MB).
-
-Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
-unless forced. This is to avoid signed vs. unsigned kernel bugs in
-block numbers that still need to be fixed.
-
-The blkid program has a new option which will more efficiently search
-for device when it is known (or expected) that only one matching
-device will be found in the system, such as when doing a lookup by
-UUID.
-
-Debian's e2fsprogs-specific initrd fragment will avoid including
-unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
-and LD_LIBRARY_PATH, and filtering out libraries found in
-/etc/ld.so.preload. (Addresses Debian Bug: #304003)
-
-Fixed a potential portability issue in the blkid programs for
-architectures where the char type is unsigned. (Addresses Sourceforge
-Bug: #1180585)
-
-Fix a bug in filefrag so that it doesn't falsely count an extra
-discontinuity when the first block found is an indirect block.
-(Addresses Debian Bug #307607).
-
-Fix blkid's recognition of cramfs filesystems, and enhance it to be
-able to handle cramfs labels.
-
-Fix debugfs's stat command to not core dump when a filesystem is not
-open.
-
-Fix e2fsck's handling of error conditions caused by the resize inode
-claiming blocks that are also used by other inodes, a filesystem
-corruption which was commonly caused by a bug in Fedora Core 3's
-resize2fs program.
-
-Fixed bug in filefrag which caused it to fail on non-ext2/3
-filesystems. (Addresses Debian Bug: #303509)
-
-If the superblock last mount time indicates that the system clock may
-not be accurate, then e2fsck will omit checking inodes' deletion time
-field for indications of a potential corrupted orphaned inode list.
-(Previously e2fsck only ommited these LOW_DTIME checks when the
-superblock's last write time looked insane.)
-
-Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
-(Addresses Debian bug #302200)
-
-Make the blkid library more paranoid about being run from setgid
-programs, and to use __secure_getenv() from libc if it is available.
-
-Fixed spelling mistakes, typos, and otherwise clarified man pages.
-(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
-and Sourceforge Bug: #1189803)
-
-Updated and fixed translations.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details.
-
-Programmer's notes:
--------------------
-
-Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
-changed to take an unsigned int for the bit number. Negative bit
-numbers were never allowed (and didn't make any sense), so this should
-be a safe change. This is needed to allow safe use of block numbers
-greater than or equal to 2**31.
-
-The compile_et program will avoid recreating generated foo_err.c and
-foo_err.h files if no changes are necessary. The compile_et program
-will also atomically replace these files to avoid a potential parallel
-build race problem on SMP systems. (Addresses Sourceforge Bug:
-#1157933)
-
-Added a new function to the blkid library, blkid_probe_all_new(),
-which only probes newly added disk devices, and change
-blkid_find_dev_with_tag() to use this function so that when a
-requested tag is not found, devices that were previously not checked
-are searched before searching all devices in the system.
-
-Added new functions to the blkid library, blkid_dev_set_search() and
-blkid_dev_has_tag().
-
-E2fsck's problem strings can now use @m and @n as abbrevations for
-"multiply-claimed" and "invalid", respectively.
-
-The e2fsprog.pot file now has an explanation of how the @-expansion
-and %-expansion works, and strings in e2fsck/problem.c which contain @
-characters now have comments in e2fsprogs.pot with the @-expansion to
-make life easier for translators.
-
-Fixed missing return values in the ext2fs library which could cause it
-to return random garbage in certain error conditions.
-
-Allow the current time to be overriden via the E2FSCK_TIME environment
-variable for use in regression tests.
-
-The test scrpit driver program now exits with a non-zero status if
-there any of its test that it ran failed.
-
-Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
-Bug: #1157933)
-
-Fixed "make check" so that it compiles correctly even when e2fsprogs'
-header files have not be installed in the system include directories.
-(Addresses Sourceforge Bug: #1180572)
-
-Fixed gcc -Wall nits.
-
-
-E2fsprogs 1.37 (March 21, 2005)
-===============================
-
-Add support for checking the validity of Extended Attributes stored in
-inodes to e2fsck.
-
-Add support for dumping the contents of large inodes to debugfs,
-including the extended attributes stored in inodes.
-
-Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
-when we create a new inode we make sure that the extra information in
-the inode (any extra fields in a large inode and any ea-in-inode
-information) is initialized correctly. This can take place when
-mke2fs creates the root and lost+found directory, when e2fsck creates
-a new root inode or a new lost+found directory, and when the user uses
-the debugfs write, mknod, or mkdir commands. Otherwise, the newly
-create inode could inherit garbage (or old EA information) from a
-previously deleted inode.
-
-Fixed a bug in e2fsck so it would notice if a file with an extended
-attribute block was exactly 2**32 blocks, such that i_blocks wrapped
-to zero.
-
-Added support to filefrag to detect files which are using the new
-experimental file extents format, and use the non-ext2 algorithm in
-that case. Fixed a bug to avoid reporting a false discontinuity if
-there is one or more unallocated blocks at the beginning of a file.
-
-Duplicated a check for noticing whether or not the number of blocks
-(given a certain blocksize) is greater than 2**32 when the
-BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
-allows mke2fs to automatically use a larger blocksize when creating a
-filesystem on a very large device when run on systems that do not
-support BLKGETSIZE64.
-
-Fix the I18N build which was broken in e2fsprogs 1.36 because the
-build system had been switched to treat the .gmo files as shipped
-files (for backwards compatibility with systems that have older GNU
-I18N tools installed), but the gen_tarball.in script was still
-removing the .gmo files from the official source distribution.
-
-Fixed various Debian packaging issues --- see debian/changelog for
-details. (Addresses Debian Bugs ##296769, #299341)
-
-Programmer's notes:
--------------------
-
-Added new functions to the e2p library which convert between a string
-and os_type: e2p_os2string() and e2p_string2os(), and used them to
-make the generated binaries more compact.
-
-Fixed a compile-time error on Darwin systems.
-
-Cleaned up the lib/ext2fs Makefile slightly.
-
-
-E2fsprogs 1.36 (February 4, 2005)
-=================================
-
-All of the patches that were applied to Fedore Core 3's
-e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
-lot of bug fixes first. Users of Fedora Core 3 are strongly
-encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
-
-Add support for filesystem with the online resizing via resize inode
-feature. Fixed numerous bugs from the Fedora patches. The Fedora
-patches also didn't bother to do any consistency checking on the
-resize inode, or add any tests to the regression test suite. The "-R
-resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
-being listed in mke2fs's usage message. All of these shortcomings
-have been corrected.
-
-E2fsck can also also fix filesystems trashed by Fedora's resize2fs
-program. In order to do this, the user must run the commands:
-
- debugfs -w /dev/hdXXX -R "features ^resize_inode"
- e2fsck -f /dev/hdXXX
-
-Optionally, the ext2prepare command can be used to re-enable online
-resizing after the filesystem has been fixed.
-
-The fsck program will now accept an optional filedescriptor argument
-to the -C option. (The Fedora version of this patch would sometimes
-cause fsck to ignore a parameter on fsck's command line in some rare
-cases, sigh.)
-
-Make sure e2fsprogs doesn't write garbage into the reserved portion of
-large inodes.
-
-Make sure resize2fs releases the blocks belonging to the old inode
-table blocks when moving the inode table. (Addresses Debian Bug:
-#290894)
-
-Skip the r_resize_inode test if resize2fs is not compiled (due to
-configure --disable-resizer)
-
-E2fsck now checks the summary filesystem accounting information, and
-if any of the information is obviously wrong, it will force a full
-filesystem check. (Addresses Debian Bug #291571)
-
-Fix e2fsck to not complain when the resize_inode feature is enabled,
-s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
-the resize inode.
-
-Fix e2fsck to note delete symlinks that contain an extended attribute
-after the ext_attr feature flag has been cleared. (Addresses Red Hat
-Bugzilla #146284).
-
-Add new utility program, copy_sparse.c, which is very useful
-for dealing with large sparse files (such as e2image files).
-
-Add support for jnl_blocks[] for debugfs's set_super_value.
-
-Fix filefrag so that it works correctly with sparse files.
-
-Filefrag -v will print first and last blocks.
-
-Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
-and dumpe2fs.
-
-Add mke2fs support so that it can support filesystems larger than 4TB
-automatically, by retrying with a 4k blocksize if the device size is
-too big to be expressed using a 1k blocksize. (Addresses Sourceforge
-bug #1106631)
-
-Change blkid to test for NTFS first because Windows sometimes doesn't
-clear enough of the parition to confuse the probing routines into
-thinking the old filesystem type is still valid. (Addresses Debian
-Bug #291990)
-
-Add support for swap partition label and uuid's in the blkid library.
-
-Add support to the blkid library to recognize Oracle ASM volumes.
-
-Make blkid -t display all devices that match the specified criteria,
-not just the first one, and work more consistently when the blkid
-cache file is not available or set to /dev/null. (Addresses Debian
-Bug #290530 and #292425)
-
-Badblocks will now correctly display block numbers greater than
-999,999,999 in its progress display.
-
-The tune2fs program will not allow the user from setting a ridiculous
-number of reserved blocks which would cause e2fsck to assume the
-superblock was corrupt. E2fsck's standards for what is a ridiculous
-number of reserved block has also been relaxed to 50% of the blocks in
-the filesystem.
-
-The blkid library will return vfat in preference to msdos, and ext3 in
-preference to ext2 (if the journalling flag is set) so that mount will
-do the right thing. (Addresses Debian bug #287455)
-
-Mke2fs will now use the -E option for extended options; the old -R
-(raid options) option is still accepted for backwards compatibility.
-Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
-
-Mke2fs will now accept a size in megabytes, gigabytes, and other units
-(via "32m" or "4g" on the command line) if the user finds this more
-convenient than specifying a block count.
-
-Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
-cache conherency problem.
-
-Debugfs now supports a new command, set_inode_field, which allows a
-user to manually set a specific inode field more conveniently, as well
-as set entries in the indirect block map.
-
-Debugfs's set_super_value command has been enhanced so that the user
-can set most superblock fields, including the date/time fields and
-some of the more newsly added superblock fields.
-
-E2fsprogs programs now accept an offset to be passed to the file
-specifiers, via the syntax: "/tmp/test.img?offset=1024".
-
-E2fsprogs programs will now accept blocksizes up to 65536; kernel
-support on the x86 doesn't exist for now, but it can be useful on
-other architectures with page sizes greater than 4k. There are 2.6
-kernel patches out there which enable this, but they are of this
-writing still experimental.
-
-The e2image command now takes the -s option which will scramble
-directory entries for raw image files.
-
-Fix a file descriptor leak in the filefrag program.
-
-Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
-present.
-
-Fix bug in debugfs where kill_file would lead to errors when deleting
-devices and symlinks. (Sourceforge Bugs #954741 and #957244)
-
-Fix bug in the blkid library when detecting the ocfs1 filesystem
-
-Remove obsolete EVMS 1.x and a.out DLL support.
-
-E2fsck will attempt to recover from a journal containing illegal blocks.
-
-Fixed two potential ordering constraint problems in e2fsck which might
-cause the filesystem to be corrupted if e2fsck is interrupted during a
-(extremely narrow) race window. Thanks to Junfeng Yang from the
-Stanford Metacompilation group for pointing this out.
-
-Fixed bug in e2fsck where it would not accurately detect whether or
-not the system is running on adaptor if the ACPI device representing
-the AC adapter didn't correspond to the what was used on IBM
-Thinkpads.
-
-Change e2fsck to accept directories greater than 32MB.
-
-Fix e2fsck so that a checkinterval of zero disables a time-based check
-of the filesystem.
-
-Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
-to the PAGER environment variable. (Addresses Debian Bug #239547)
-
-Tune2fs will not mark rewrite the superblock if the feature bitmasks
-are not modified.
-
-The debugfs program will set the filetype information when creating a
-link.
-
-Add debugfs -d option to use a separate source of data blocks when
-reading from an e2image file.
-
-Add e2image -I option which allows the e2image metadata to be
-installed into a filesystem.
-
-Fixed bug in the badblocks program which caused "done" to always
-appear in english even when a translation was available. (Addresses
-Debian Bug #252836)
-
-The blkid program has a new option -o which controls the output format
-of the blkid program; this is makes blkid more convenient to use in
-shell scripts.
-
-Fix a minor bug in uuid library, which was not using the full 14 bits
-of clock sequence when generating UUID's.
-
-Fix a Y8.8888K problem in the uuid library.
-
-Logsave now creates a new session id for itself to avoid getting
-killed by init whan transitioning between init levels.
-
-Change the licensing of the UUID library to be the 3-clause BSD-style
-license; this allows Apple to use the uuid library in Darwin.
-
-Add ocfs and ocfs2 probe support into the blkid library.
-
-Fix a memory and file descriptor leak in the blkid library.
-
-The blkid library will revalidate the device if the system time is
-earlier than last verification time of the device, since that
-indicates that the system time is probably nottrustworthy.
-
-The blkid library will override the default location of the blkid.tab
-file by the BLKID_FILE environment variable, if it is available.
-
-Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
-
-Add various portability fixes for lame new versions of glibc, Darwin
-and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
-Bugs #239934, #264630, #269044, #255589, #289133)
-
-Add support for Windows 9x/NT under Cygwin.
-
-Updated and clarified various man pages. (Addresses Debian Bugs #236383,
- #241940, #238741, #242995, #256669, #268148, #256760, #273679)
-
-Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
-
-Update the rpm spec files so that it works better with Fedora core 2
-and RH9.
-
-Fixed various Debian packaging issues (see debian/changelog). In
-particular, fixed the Debian initrd scripts. (#241183, #248050,
-#253595, #247775)
-
-
-Programmer's notes:
--------------------
-
-Fixed various gcc -Wall warnings.
-
-The uuid library now has new functions uuid_unparse_upper() and
-uuid_unparse_lower() which forces the case of the hex digits to be
-upper case, or lower case.
-
-The build process has been speeded up by enhancing the subst program
-to update the modtime on the generated files even when the generated
-file hasn't changed.
-
-The uuid library now uses C99 stdint.h types instead of custom types.
-
-Updated config.guess and config.sub with newer versions from the FSF.
-
-Removed out of date .cvsignore files from the source distribution.
-
-The ext2fs_unlink() function will return an error if both the name and
-inode number are unspecified, to avoid doing something surprising
-(such as unconditionally deleting the first directory entry).
-Directory entries are now deleted by coalescing them with the previous
-directory entry if possible, to avoid directory fragmentation. This
-is not an issue with the e2fsprogs suite, but may be a problem for
-some of the users of libext2fs, such as e2tools.
-
-Add support for version numbers of the form "1.36-rc1".
-
-Fix build of mke2fs.static.
-
-Add basic ext2fs library support for large (EA in inode) inodes.
-
-The test_io mechanism can now abort after n reads or writes to a
-particular block. The block is specified by TEST_IO_BLOCK environment
-variable, and the read/write count by the TEST_IO_READ_ABORT and
-TEST_IO_WRITE_ABORT environment variables. The block data is now only
-dumped if the 0x10 bit is set in TEST_IO_FLAGS.
-
-UUID_DEFINE() in the uuid library now creates a static variable, with
-__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
-be used in header files.
-
-Add support for the install-strip and install-shlibs-strip targets, as
-suggested by the GNU coding guielines. "make install" no longer
-strips the binaries which are installed.
-
-Remove support for the --enable-old-bitops configure option which was
-only for very old sparc systems.
-
-Remove support for --enable-clear-htree; this was only needed during
-the early development of the htree patch.
-
-Use Linux-kernel-style makefile output so it is easier to see compiler
-warnings.
-
-Update gettext files to version 0.14.1.
-
-Update to use autoconf 2.5x.
-
-Improved support for compiling e2fsprogs under dietlibc.
-
-Make e2fsprogs portable to Solaris and FreeBSD systems.
-
-Add blkid_verify(), blkid_get_library_version(), and
-blkid_parse_version_string() functions to the blkid library.
-
-Add pkg-config files for e2fsprogs's libraries.
-
-Fix "make uninstall" to so that it removes everything that is installed.
-
-Add a configure --enable-maintainer-mode option which enables the
-makefile rules to rebuild the configure script from configure.in, and
-to reubuild the .gmo files in po directory.
-
-Drop the sparc assembly bitwise operations; it's less efficient
-than the GCC 3.4 compile code and triggers compiler warnings on
-sparc64. Thanks to Matthias Andree for his analysis and suggestions.
-(Addresses Debian Bug #232326)
-
-
-E2fsprogs 1.35 (February 28, 2004)
-==================================
-
-E2fsck has a new -k option, which in conjunction with the -c options,
-preserves the existing badblocks list.
-
-Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
-
-E2fsprogs will now deal correctly with symlinks that contain
-extended attribute information, which can be created using SE Linux.
-(Addresses Debian Bug #232328)
-
-Remove a double longjump into an invalid stack frame bug in e2fsck.
-(This was during an abort sequence, which normally worked on Linux and
-caused a core dump on other operating systems.)
-
-Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
-(the NLS library will replace "" with the .po header information).
-
-Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
-dump due to a division by zero error. (Addresses Debian bug #207082)
-
-Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
-when reconnecting a directory requires creating a lost+found
-directory. (Addresses Debian bug #219640).
-
-Fixed a bug where e2fsck would bomb out if a journal needed to be
-replayed when using an alternate superblock.
-
-E2fsck will give an extra grace period before actually forcing a check
-if the laptop is running on battery. The next time fsck runs while
-the system is on the AC mains, or after the grace period is exceeded,
-the filesystem will be checked. (Addresses Debian bug #205177)
-
-E2fsck will inform the user when there are 5 or fewer mounts before a
-filesystem check will be forced. (Addresses Debian bug #157194)
-
-Fix e2fsck's handling of corrupted indirect blocks in the bad block.
-We now correctly handle the case where there is an overlap between a
-block group descriptor or a superblock and a bad block indirect block.
-In the case where the indirect block is corrupted, we now suggest
-"e2fsck -c".
-
-Fix byte swap bugs in e2fsck that caused the journal backup location
-in the superblock and symlinks created by SE Linux to be cleared
-by e2fsck on big-endian machines. (Addresses Debian bug #228723)
-
-E2fsck -c now replaces the current list of bad blocks with the ones
-found by badblocks.
-
-Fix bugs in e2fsck and tune2fs which could cause a core dump if a
-non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
-
-Fix a potential bug in e2fsck which could cause it to core dump when
-trying to print the location of the backup superblock.
-
-Protect against a potential core dump in e2fsck when printing a
-message about backup superblocks.
-
-Add support for backing up the journal inode location in the
-superblock. E2fsck will automatically save the journal information in
-the superblock if it is not there already, and will use it if the
-journal inode appears to be corrupted. ext2fs_add_journal_inode()
-will also save the backup information, so that new filesystems created
-by mke2fs and filesystems that have journals added via tune2fs will
-also have journal location written to the superblock as well.
-Debugfs's logdump command has been enhanced so that it can use the
-journal information in the superblock.
-
-E2fsck will now update all superblocks when moving the journal inode.
-
-Shrink the size of the e2fsck executable by moving some initialized
-variables to the BSS segment.
-
-E2fsck will avoid printing the ^A and ^B characters which bracket the
-progress bar when stdout and stdin are a tty device instead of a pipe
-to another program. (Addresses Debian bug #204137)
-
-Debugfs's mkdir command will automatically expand the directory if
-necessary. (Addresses Debian Bug: #217892)
-
-Fixed a bug in debugfs so that copying a file from /dev/null uses the
-correct mode bits. (Addresses Debian Bug: #217456)
-
-If the environment variables DEBUFS_PAGER and PAGER are not set,
-debugfs now searches for the appropriate pager to use, beginning with
-/usr/bin/pager, and then falling back to 'more' and 'less'.
-(Addresses Debian bug #221977)
-
-Debugfs will now support 2.6 device numbers where the major or minor
-number may be larger than 255. (Addresses Sourceforge bug #865289)
-
-Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
-
-Chattr now stops processing options when it sees '--'. (Addresses
-Debian bug #225188)
-
-Fix regression tests so they work correctly when e2fsprogs is compiled
-with configure --disable-htree.
-
-Fix bug in uuid library when there is no network card and the library
-is generating a time-based uuid. The random MAC address was not
-correctly generated to be a multicast address.
-
-Add compile_et extensions from Heimdall that were missed the first time
-around.
-
-Fix bug in badblocks when using O_DIRECT; we need to make sure that
-we're reading from an offset which is page aligned. For read-only and
-read-write tests, we try to recover after an error so that we can
-continue reading on page-aligned boundaries. (Addresses Debian Bug
-#203713)
-
-Badblocks now checks 64 blocks at a time instead of 16. (Addresses
-Debian bug #232240)
-
-Updated and clarified various man pages. (Addresses Debian Bug
-#206845, #222606, #214920, #232406)
-
-Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
-
-Fixed various Debian packaging issues (see debian/changelog).
-
-Programmer's notes:
--------------------
-
-Fixed a build problem so that e2fsprogs would compile with the
---enable-profile option to configure selected. (Addresses Sourceforge
-bug #811408)
-
-Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
-Bugzilla Bug #112448)
-
-Centralize code which calculates the location of the superblock
-and block group descriptors so that it is in a single library routine.
-
-Added two new functions, ext2fs_file_open2() and
-ext2fs_inode_io_intern2() which take a pointer to an inode structure.
-
-Fix compile_et to output the correct prototype for
-initialize_xxx_err_table_r() in the header file. (Addresses Debian
-bug #204332)
-
-In the lib/et makefile, make sure com_err.info is deleted on "make clean".
-
-Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
-present. This is for when we try stuffing an int into void * pointer.
-
-Fix type-punning which can cause gcc 3.x to miscompile code by getting
-confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
-and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
-**'. The EVMS code uses an ugly union approach since we don't want to
-modify the EVMS interfaces.
-
-Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
-aid build process on systems can use invoke GNU make as "gmake".
-
-Added regression testing for mke2fs.
-
-Fixed gcc -Wall nitpicks.
-
-Fixed various compiler warnings.
-
-Add portability fixes for FreeBSD and for using fsctl under Darwin to
-support ext2 ioctl's.
-
-
-E2fsprogs 1.34 (July 25, 2003)
-===============================
-
-Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
-a tight loop while waiting for a child fsck to exit in some cases.
-This burns CPU times which slows down the low-level filesystem check.
-
-Added code to mke2fs to assure that the default block size for a
-filesystem is at least as big as the sector size of the device, if it
-can be determined.
-
-Changed mke2fs and resize2fs to round the default size of a filesystem
-to be an even multiple of the VM pagesize in order to avoid a Linux
-kernel bug introduced when the storage of the buffer cache was moved
-into the page cache.
-
-Mke2fs will warn the user when creating a filesystem with journaling
-and a blocksize greater than 4096. (Addresses Debian bug #193773)
-
-Fixed a bug in resize2fs which caused it to fail on filesystems with a
-non-empty bad block list. Resize2fs now discards any blocks on the
-badblock list which are no longer part of the filesystem as the result
-of a filesystem shrink. (Note: this means that shrinking and then
-enlarging a filesystem is no longer a reversible operation;
-information about bad blocks in the part of the filesystem which is to
-be chopped off will be lost.)
-
-Changed resize2fs so the user can use prefixes to specify the units of
-the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
-and to make the error and informational messages explicitly display
-the blocksize used by the filesystem, in order to avoid confusion.
-(Addresses Debian bug: #189814)
-
-Added a new debugfs command, dump_unused, which dumps the contents of
-all unused blocks to stdout. (Useful as an emergency try-to-find
-deleted data command.)
-
-Added a new debugfs command, imap, which prints the location of a
-specified inode in the inode table.
-
-Fixed a bug in the badblocks program which caused it to use one bit of
-randomness in its non-destructive read/write test, instead of using a
-full 8 bits of randomness.
-
-Added a new option (-t) to badblocks, which allows the user to control
-the test pattern(s) used when checking a disk.
-
-The blkid probe function now more correctly detects UDF filesystems.
-
-Fixed a bug in the blkid library which caused it to not update its
-cache if a filesystem changes from having a label to not having a
-label.
-
-Fixed a bug in the blkid library wihch could avoid an infinite loop
-in blkid_find_dev_with_tag() if /proc is not mounted and there the
-/etc/blkid.tab file has not yet been created.
-
-Fixed the badblocks program so that the destructive read/write test
-honors the -c option, and to use O_DIRECT when possible to avoid
-thrashing the system block buffer cache.
-
-Fixed various NLS issues.
- - Added Czech and Swedish translations
- - Removed testing NYC translation
- - Fixed NLS support for message abbrevations in e2fsck
- - Remove de-utf.po, since we shouldn't have two versions using different
- charset encodings.
- - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
- simplify the statistics reporting in e2fsck.
-
-Changed configure.in so that its defaults for *BSD systems no longer
-build an fsck wrapper, and not to install in /usr/local by default.
-
-Fixed some minor spelling errors/typo's in e2fsck and the configure
-script.
-
-Fixed various Debian packaging issues (see debian/changelog).
-
-Updated and clarified man pages. (Addresses Debian Bug #195616)
-
-Programmer's notes:
--------------------
-
-Fix gcc -Wall nitpicks.
-
-Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
-NLS support by default. (Added partial workaround for gettext/Darwin
-incompatibility problems.)
-
-Added full MIT KRB5 and Himdall compaibility support to the com_err
-library and the compile_et program. (Addresses Debian bug #191900)
-
-Added the blkid_known_fstype() function to the blkid library, which
-returns true if it is passed a filesystem type which is recognized by
-the blkid probing functions.
-
-Improved the documentation for the blkid library.
-
-Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
-returns the hardware sector size of a device, if it is available.
-
-Added a dependency in the blkid library's .so file to the uuid
-library, since the former uses the latter. (Addresses Debian bug
-#194094)
-
-Added --with-diet-libc and --disable-evms to the configure script.
-
-Fixed a minor memory leak in the badblocks program.
-
-Fixed a portability problem in tune2fs --- not all systems have strptime().
-
-Fixed a portability problem in debugfs with the use of getopt() more
-than once. Old-style BSD, new-style BSD, and Linux C libraries all do
-things differently.
-
-Add support Windows support to ext2fs_get_device_size().
-
-Added (normally disabled) debugging code to the Unix I/O manager which
-causes it to disable all userspace caching if the NO_IO_CACHE is
-defined.
-
-Changed the test I/O manager so it can always be linked into e2fsck,
-mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
-configure script. The test I/O manager will only print any debugging
-information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
-variables are set, which specifies which I/O operations are logged and
-a block number to watch, respectively. The log messages are sent to
-stderr by default, unless a filename is specified via the
-TEST_IO_LOGFILE environment variable.
-
-
-E2fsprogs 1.33 (April 21, 2003)
-===============================
-
-Added a new utility program, logsave, which captures the output of a
-command in a log file, even if the containing directory hasn't been
-mounted yet (in which case the it saves the output in memory until it
-can write out the logfile). This is useful for capturing the
-output of fsck during the boot sequence.
-
-Fixed some portability problems that were causing problems under
-the Cygwin32 environment.
-
-Mke2fs now interprets a negative number to the -b option as a minimum
-block size.
-
-Fixed a bug in mke2fs which was incorrectly checking the argument to
-the -g option if the default block size was used. (Addresses Debian
-bug #188319)
-
-Fsck now explicitly ignores tmpfs and devpts, and it will complain if
-it can not find filesystem checkers for jfs, reseirfs, and xfs.
-
-E2fsck now updates the global free block and inode counters from the
-block group specific counters quietly. This is needed for an
-experimental patch which eliminates locking the entire filesystem when
-allocating blocks or inodes; if the filesystem is not unmounted
-cleanly, the global counts may not be accurate.
-
-Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
-2.0 is not yet supported; this only pulled in the bug fixes: fixed
-possible hangs caused by bugs in calling waitpid, and not setting the
-pipe to non-blocking mode; also fixed a file descriptor leak; made
-sure all functions call log entry/exit functions.)
-
-Badblocks now flushes its output file as bad blocks are discovered.
-
-The uuid library is now more paranoid about assuming the correctness
-of the /dev/random device; it mixes in a stream of bytes from
-random/srandom, just in case.
-
-Update Debian files to reflect the fact that I am now the Debian
-maintainer of e2fsprogs. Other various Debian-specific packaging
-cleanups.
-
-Move the source tarball generation functions from the top-level
-makefile to the util/gen-tarball script.
-
-Updated the Turkish .po translation file.
-
-Added Heimdal and MIT krb5 extensions to the com_err library to make
-it more compatible with com_err libraries from those distributions.
-
-Changed dumpe2fs to always display the superblock fields relating to
-the journalling and/or directory indexing feature even if those
-features are not enabled.
-
-Updated and clarify copyright statement vis-a-vis alpha releases of
-e2fsprogs.
-
-The ss library will now try to dynamically link to the readline
-library and use it if it is present in the system. This means that
-the debugfs program now has line editing and history features. The
-SS_READLINE_PATH environment variable is used to find a readline or
-readline-compatible library.
-
-E2fsck now finds most duplicate filenames (all when rebuilding all
-directories via the -D option) and offers to delete or rename
-duplicate filenames/directory entries. (Addresses Debian Bug #176814).
-
-Fix bug in e2image. When writing out a raw image file, include data
-blocks from symlinks that do not store the symlink within the inode.
-
-Fix bug in resize2fs which incorrectly moved the block and inode
-bitmaps for sparse superblock filesystems and incorrectly marked
-blocks as in use. (Addresses Debian bug #174766)
-
-Added a new shared library, the blkid library, which efficiently
-allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
-and UUID filesystem specifiers without needing to search all of the
-devices in the system. Instead, the device is looked up in a cache
-file, and then verified to make sure the blkid cache is correct.
-
-Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
-the device name, using the blkid library. (Addresses Debian bugs
-#166048, #179671)
-
-Fsck now supports backslash escapes in /etc/fstab so that \040 can be
-used for spaces in device labels.
-
-Removed 32-bit limitations for debugfs's dump command.
-
-If the user specifies a large number of inodes, Mke2fs will
-automatically adjust the number of blocks per group to find a valid
-set of filesystem parameters.
-
-Add workaround to detect broken MD devices where when some of the
-underlying devices are marked read-only, writes to the MD device are
-silently dropped. E2fsck will detect if there is an attempt to run
-the journal twice, and abort with an error if this is the case.
-(Addresses IBM Bugzilla bug #1226)
-
-E2fsck will print an error if more than one of the -p/-a, -n or -y
-options are specified.
-
-E2fsck will fix HTREE corruptions in preen mode, without stopping the
-boot process. This is needed because the 2.4 ext2 filesystem
-accidentally had the INDEX_FL backwards compatibility code removed.
-
-Mke2fs no longer creates filesystems with the dir_index flag set by
-default; the user has to specifically request it.
-
-Update and clarified various man pages. (Addresses Debian bugs
-#173612, #175233, #175113, and #170497, #185945, #188318)
-
-Created man page for the mk_cmds program (from the libss library).
-
-Programmer's notes:
--------------------
-
-Fix various gcc -Wall nits.
-
-Fixed a lot of portability problems that caused e2fsprogs not to build
-successfully under Solaris and Apple/Darwin.
-
-Fixed a Makefile dependency to allow building e2fsprogs using parallel
-make jobs.
-
-Changes to create a subset distribution which consists only of the
-et, ss, uuid, and blkid libraries. The configure script and top-level
-makefile were changed to support working with a subset distribution.
-
-Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
-actually used, and might people who are looking for
-EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
-
-Updated debian files to fix a number of Lintian warnings.
-
-Updated config.guess and config.sub with newer versions from the FSF.
-
-Removed unnecessary libraries from being linked into the fsck, lsattr,
-chattr, and blkid executables.
-
-E2fsprogs 1.32 (Nomvember 9, 2002)
-==================================
-
-Fixed a bug in the Unix I/O routines which caused needless writebacks
-of clean blocks from the unix_io cache (they were erroneously marked
-as being dirty, so they were getting written back to disk before
-getting evicted from the disk cache). This was harmless, but it
-significantly slowed down e2fsck.
-
-Made some other minor optimizations to the Unix I/O routines to save a
-small amount of CPU time.
-
-Updated internationalization files.
-
-
-E2fsprogs 1.31 (Nomvember 8, 2002)
-==================================
-
-Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
-compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
-handling for child process that die unexpectly. Add a hack to force
-mkfs to create filesystems that won't cause problems with hardware
-that has 2k or 4k minimum blocksize requirements. Read from child
-processes in non-blocking mode, so that the GUI continues to update.
-
-Fix e2fsck so that it returns the appropriate exit code when the root
-filesystem has been changed, so that system's rc scripts will be told that
-the system needs to be rebooted.
-
-Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
-was set, some of the descriptor blocks that should have been written
-out were getting skipped.
-
-Changed e2fsck to force out changes to the backup copies of the
-superblock and block group descriptors when important changes are made
-to those data structures.
-
-Fix a bug where e2fsck could erroneously mark a filesystem as being
-clean if a check of dirty filesystem is interrupted with a ^C. (Bug
-introduced in e2fsprogs 1.28.)
-
-If journal debuging is enabled using --enable-jbd-debug, the debugging
-level is now set via the E2FSCK_JBD_DEBUG environment variable.
-
-If byteswapping support is disabled using configure --disable-swapfs,
-skip the tests which depend on byte-swapping, so that "make check"
-won't bomb out.
-
-Lshattr will now display the indexed directory flag. Also, some of
-the more esoteric compression flags are supressed unless compression
-support has been enabled.
-
-Update man pages.
-
-
-E2fsprogs 1.30 (October 31, 2002)
-=================================
-
-When resizing a filesystem, and inodes need to moved, resize2fs will
-update the inode's ctime field, and the mtime field of the containing
-directories, so that incremental backups using dump/restore will work
-correctly.
-
-In order to avoid spurious errors, e2fsck wil check the last
-superblock write time to determine whether or not it can safely use
-the LOW_DTIME checks to determine if there are inodes on the orphan
-inode linked list that had somehow gotten disconnected. (Addresses
-Sourceforge bug #620980)
-
-Partition in /proc/partitions that being with the string "lvm" are
-considered real partitions even if they do not end with a number.
-
-Fixed a bug in the the uuid generation function, where if /dev/urandom
-is not present, but /dev/random is, and there isn't sufficient
-entropy, the get_random_byte function could spin a loop forever.
-
-E2fsck, mke2fs, etc. will now reliably notice when image files are
-mounted using the loopback interface. (Addresses Sourceforge bug
-#619119)
-
-When flushing buffers (as is done by badblocks, for example) check to
-see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
-FDFLUSH ioctl which causes the MD device driver which causes confusing
-syslog messages about obselete ioctl messages. (Addresses Sourceforge
-bug #545832).
-
-Debugfs's write command now checks to see if the destination filename
-exists before creating it. (Addresses Sourceforge bug #478195.)
-
-When installing man pages, search for compressed man pages using all
-commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
-
-Fixed a bug in fsck where multiple filesystems specified on the
-command were not being checked in parallel due to a logic bug
-introduced to support the FSCK_MAX_INST environment variable.
-
-We have added a new superblock field, s_mkfs_time, which indicates
-when a filesystem was created. It is set via mke2fs, and printed out
-by dumpe2fs, but is not actually touched by the kernel.
-
-Dumpe2fs has been made more robust by not aborting if there is an
-error reading the block/inode bitmaps; instead it will still print out
-the location of the block/inode bitmaps and inode table.
-
-Add support for the an alternative block group descriptor layout which
-allows for on-line resizing without needing to prepare the filesystem
-in advance. (This is the incomat feature flag meta_bg.)
-
-Add support for storing default mount options in the superblock, so
-that the filesystem can be mounted with specific mount options without
-needing to specify them on the mount command line or in the /etc/fstab
-file.
-
-Add support for a new inode flag, which is to be used for indicating
-the top of directory hierarchies for the Orlov block allocator.
-
-Fix e2fsck so that if it creates the lost+found directory, it does so
-with the more apporpriate permissions of 0700. Also change
-mklost+found so that it also creates the directory 0700.
-
-Fixed format bug in e2fsck if NLS is in use.
-
-Add a German translation for e2fsprogs's NLS support.
-
-Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
-the beginning of the inode table. This won't matter much, since if
-there is a bad block at the beginning of the inode table, the root
-directory won't be available. But at least e2fsck won't crash in this
-case.
-
-Fixed endian problems in the htree code for e2fsck and debugfs.
-
-When byte-swapping a filesystem on a PPC architecture, byte-swap the
-bitmaps since the historical big-endian ext2 variant had byte-swapped
-bitmaps, and the ext2fs library assumes this. This fixes the
-regression test suite on PPC machines.
-
-Fix e2image so that it handles a bad block in the inode table
-appropriately.
-
-E2fsck now uses a more sophisticated algorithm to salvage corrupted
-directories that recovers more information in the corrupted directory
-block.
-
-E2fsck now performs additional consistency checks on indexed (HTREE)
-directories.
-
-Fix bug where efsck might get confused about whether a completely
-empty directory block is an empty leaf block or an interior htree
-node. This could cause e2fsck to get confused into think that a valid
-indexed directory was corrupted.
-
-E2fsck no longer creates an empty directory entry at the end of a
-directory block when optimizing a directory. This would cause some
-earlier versions of the dxdir kernel code to corrupt the directory
-when attempting to split a node containing an empty directory entry.
-
-E2fsck could sometimes in rare circumstances leave the indexed flag
-set after a small directory was optimized by compressing it instead of
-indexing it. (This should never happen in real life, since
-directories that small wouldn't have been indexed, but better safe
-than sorry.)
-
-E2fsck now only updates the master superblock in all cases. This
-slightly shortens its run time.
-
-Ext2ed can deal with directory entries of length 0; previously it
-would get stuck in an infinite loop.
-
-Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
-specifiers. (Sourceforge patch #613447)
-
-Badblocks will now work correctly on read-only devices such as
-CD-ROM's. (Sourceforge patch #600451)
-
-Updated and clarified man pages. (Addresses Debian bug #167108)
-
-
-E2fsprogs 1.29 (September 24, 2002)
-===================================
-
-Fixed a bug in e2fsck which could corrupt a directory when optimizing
-it (via the -D option) or rebuiliding the hash tree index with a 1 in
-512 probability, due to a fence post error.
-
-Fixed a bug in the LVM support code which caused LABEL='xxx' not to
-work correctly.
-
-Mke2fs now enables the directory indexing flag by default. (Since
-this is a compatible feature flag, it's safe to do so.)
-
-Tune2fs will support setting the directory indexing feature flag. It
-will automatically set up the default hash algorithm and hash seed
-fields in the superblock.
-
-If the bone-headed user enters the root filesystem twice in
-/etc/fstab, the -R option which skips the root filesystem will skip
-all of them. (Addresses Debian bug #159423). Note! This is not a
-precedent for dealing intelligently with any other kind of doubled
-entry in /etc/fstab!
-
-
-Programmer's notes:
--------------------
-
-Removed perror declaration in lib/et/internal.h. All modern systems
-can be expected to define perror() these days. Besides, the lib/et
-code wasn't using perror at all anyway. :-)
-
-
-E2fsprogs 1.28 (August 31, 2002)
-================================
-
-Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
-for setting the htree flag is not included yet, although it can be
-manually turned on via the debugfs program.
-
-Clarified e2fsck error message which is printed when it cannot find
-sufficient contiguous block when relcating filesystem metadata.
-
-Added support for building an EVMS plugin module for ext2/3. This
-module is substantially the same as the EVMS module shipping with EVMS
-1.1, with one or two bugfixes. E2fsprogs can also build this plugin
-for use with EVMS 1.0 (which did not include the ext2 plugin module),
-if the configure --enable-old-evms flag is given.
-
-Fsck will search through EVMS volumes when trying to resolve
-filesystem specifications such as LABEL=xxx or UUID=xxx.
-
-Added a new utility program, /sbin/findfs, which will return
-filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
-the device name.
-
-Update and clarified various man pages. (addresses Debian Bug #145044,
-#146437, #131350, #151990, #144621, #141938)
-
-If there are no filesystems specified on fsck's command line, fsck now
-treat that as if the -As options were given. Previously it would
-simply do nothing. (Addresses Debian Bug #153102)
-
-Mke2fs no longer treats a failure to be able to clear the MD signature
-at the end of the filesystem as a fatal error. (Addresses Debian Bug
-#155007)
-
-The e2p library functions (which are used by lsattr and chattr) now
-double check to make sure the file is a regular file or directory
-before attempting to use the ext2 ioctls. Some device drivers
-unfortunately respond to the ext2 ioctl's with unknown behaviour.
-(Addresses Debian Bug #152029).
-
-The extended attribute handling has been updated to correspond with
-the latest V2 bestbits ACL code.
-
-Fixed bug in e2fsck which caused it to not clear the dtime field when
-processing truncated inodes on the orphan list. This could cause data
-loss(!) if a filesystem is rebooted before a truncate has been
-committed.
-
-E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
-algorithms. This makes e2fsck much faster in the case of severely
-corrupted filesystems where a large number of blocks are claimed by a
-large number of inodes. (Thanks to the 2.5 IDE device driver for
-inspiring this work.)
-
-Resize2fs has been significantly sped up when shrinking and expanding
-a filesystem by a very small number of blocks (for example, when EVMS
-is converting a partition to be an EVMS legacy volume).
-
-Added a new option to e2fsck, -D, which will optimize or compress all
-of the directories in the filesystem.
-
-E2fsck now catches SIGINT and SIGTERM to make sure it will can
-properly clean up and only exit at safe points. Fsck will pass
-SIGINT/SIGTERM to its child processes, and wait until they have all
-exited before it exits.
-
-The uuid parsing code in the uuid library now properly complains when
-an illegally formated uuid is presented to it. (Addresses Debian bug
-#152891)
-
-Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
-and 2.4.17, since the workaround can cause problems when using a 2.4
-kernel with an old version of glibc built with the 2.2 headers.
-
-Fixed a bug in mke2fs where it wasn't properly clearing the initial
-superblock used by other filesystems. (Addresses Debian bug #147256.)
-
-Added support for the synchronous directory feature written by Andrew
-Morton.
-
-The debugfs program can delete directories using the rmdir command.
-
-Add support for 8k and 16k filesystems (for systems with page sizes
-that are greater or equal to 8k or 16k, respectively). Note that
-these filesystems can not be mounted on x86 systems, or other systems
-with only 4k page sizes, due to limitations in the current Linux VM
-code.
-
-Resize2fs requires that the filesystem state be valid and have no
-errors; otherwise, e2fsck -f must be run first. (Previously it simply
-required that the last fsck time be greater than the last mount time.)
-
-Configure now defaults the man pages directory to /usr/share/man on
-Linux systems.
-
-E2fsck now offers to truncate inodes which contain too many blocks (so
-that i_blocks would overflow. Also fixed handling of large sparse
-files.
-
-E2fsck now more completely checks for symlink validity, including
-requiring NULL termination and length checks.
-
-E2fsck will offer to try forcing a disk write to remap a bad block
-after finding a read error when reading a filesystem metadata block.
-
-Fixed a bug in debugfs which caused the -b and -s options to crash
-debugfs, as well as breaking the testb, setb, and clearb functions.
-
-Added a bmap command to debugfs which calculates the logical to
-physical block mapping for a particular inode.
-
-Fixed a bug in code which checked to see if a device was mounted which
-sometimes (rarely) failed in the case of a plain file.
-
-Fixed a bug in resize2fs where when it reported an error, it would
-print a message erroneously indicating that the filesystem had been
-resized before it aborted.
-
-When resizing a plain file which is smaller than the requested size,
-resize2fs will attempt to extended the file so that programs like
-e2fsck will not complain that the file is too small.
-
-Resize2fs will print the actual new size of the filesystem when it is
-finished resizing.
-
-Fixed a bug in debugfs where "ls -l" would report incorrectl file type
-information on big-endian systems.
-
-
-Programmer's notes:
--------------------
-
-Fixed collisions with C++ reserved words.
-
-Added portability fixes for building e2fsprogs on the HURD and AIX.
-
-Added the ext2ed program for creation of test cases. (ext2ed has many
-limitations and bugs which make it unsuitable for production use.)
-
-The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
-flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
-name_len field is byte swampped on big-endian machines, since in the
-V2 structure, name_len is a char field which is doesn't need to be
-byte swapped --- except if an old-style kernel had byte-swapped the
-name_len field as part of the V1 structure.
-
-
-E2fsprogs 1.27 (March 8, 2002)
-==============================
-
-The warning messages for mke2fs now go to standard error.
-
-Fixed to make sure "make check" runs all of the test programs with
-LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
-
-The mke2fs program checks the boot sector for the BSD disk label, and
-avoids erasing it if it is there.
-
-Fixed a bug in e2fsck which caused it to core dump if the journal
-inode was missing when it was supposed to be there.
-
-E2fsck now prints ranges in pass 5 when printing deltas for the block
-and inode bitmaps.
-
-Debugfs's "ls -l" command now will print out the file type information
-in the directory entry.
-
-Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
-mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
-
-Debugfs can now examine the experimental directory indexing
-information.
-
-Fixed bug in debugfs which caused it to core dump if modify_inode is
-called without an open filesystem.
-
-The debugfs lsdel command now runs its output through a pager first.
-
-When installing manual pages, remove the compressed manual pages first.
-
-Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
-
-Fix the 2.4 resource limitation workaround introduced in 1.26 which
-actually broke things on mips32, sparc32, and Alpha platforms.
-
-Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
-(which is required by the newer libintl libraries).
-
-Programmer's notes:
--------------------
-
-Fixed various gcc -Wall complaints.
-
-Fixed a few memory leaks in the e2fsck journaling code, and in the
-ismounted code checking for a swap device.
-
-Add new inode I/O abstraction interface which exports an inode as
-an I/O object.
-
-Exported ext2_file_flush as a public interface.
-
-In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
-
-Lots of small random portability fixes to make e2fsprogs build under
-AIX --- even without the 5L compatibility toolkit, and even using the
-uber-crippled AIX native C compiler.
-
-
-E2fsprogs 1.26 (February 3, 2002)
-=================================
-
-Dumpe2fs will keep going now if the bad block inode can't be read.
-(Previously it stopped with a fatal error.)
-
-E2fsck will now give an opportunity to run the journal even if the
-recovery flag is not set. This is the default behaviour if e2fsck is
-using a backup superblock, since the needs_recovery flag will never be
-set in the backup superblock copies.
-
-E2fsck now automatically finds the backup superblock/group descriptors
-even when the primary superblock is completely destroyed for 2k and 4k
-filesystems. (Previously it just guessed/assumed that we were dealing
-with a 1k filesystem in that case, and users had to manually specify
-the backup superblock number.)
-
-Fixed a bug in e2fsck where it dereferences a null pointer when there
-is a problem opening a filesystem in preen mode.
-
-E2fsck now handles external journals correctly; previously it trashed
-the external journal device if the journal needed to be replayed.
-
-Work around ulimit incompatibility problem caused by recent 2.4
-kernels; the unix IO module will automatically try to set any resource
-limits to be infinite on startup.
-
-Fixed a bug in e2fsck where it wasn't allocating a new block or inode
-bitmap if it wasn't present and the blocksize was 2k or 4k.
- (Addresses Debian Bug #116975)
-
-E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
-clearing the new V2 fields if they do not make sense or if the ext3
-superblock is version 1 superblock.
-
-E2fsck will automatically relocate the ext3 journal from a visible
-file (i.e., /.journal) to an hidden inode if the filesystem has been
-opened read/write. This allows the users to add a journal while the
-filesystem is mounted, but the next time the system is rebooted, the
-journal file will disappear. This avoids problems with backups,
-stupid operators with superuser bits, etc.
-
-Fix a bug in fsck where it would not support a filesystem type of
-"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
-
-Fsck now supports fstab entries of the form "ext3,ext2". It will also
-automatically identify reiserfs filesystems.
-
-The number of processes spawned by fsck can now be limited using the
-FSCK_MAX_INST environment variable.
-
-Fsck now searchs the LVM proc hierarchy to find logical volumes which
-should be searched for UUID and label information.
-
-Work around a bug in 2.4.10+ kernels by trying to unset the filesize
-limit if at all possible, when opening a block device. (The filesize
-limit shouldn't be applied against writes to a block device.)
-
-In mke2fs and e2fsck, specifying the -c option twice will now do
-a read/write test on the disk. Update the man pages to encourage
-using the -c option, and to discouraging running badblocks separately,
-since users tend to forget to set the blocksize when running
-badblocks.
-
-Mke2fs now automatically clears the immutable attribute on a
-pre-existing .journal file left over from a previous failed attempt to
-add a journal to an alreadyy-mounted filesystem.
-
-Fixed mke2fs's exit codes to consistently indicate when the mke2fs
-operation failed.
-
-Mke2fs now creates the lost+found directory with permissions of 0700,
-so that files that had previously lived in protected directory are
-safe if they get dropped in lost+found and the system administrator
-doesn't deal with immediately. (Addresses Debian #bug 118443)
-
-Mke2fs and e2fsck (and all programs that use the
-ext2fs_check_if_mounted function) will now properly identify that a
-device is mounted, even in cases where devfs has confused things with
-multiple devices names with the same identity, or if a dim-witted
-system administrator has done something stupid like creating device
-file aliases in their home directory. Also now checks for swap devices
-by using /proc/swaps. (Addresses Debian bug #106622)
-
-Added a new option (-T) to tune2fs which sets the time a filesystem
-was last checked.
-
-Speed up e2image when creating sparse raw image files by optimizing
-away excess lseek() system calls.
-
-Fix support of large (> 2GB) files when used as a filesystem in
-mke2fs, tune2fs, debugfs, and findsuper.
-
-Debugfs's stat and icheck commands now properly deals with large (>
-2GB) files.
-
-Debugfs's set_super_value command now prints out the list of valid
-superblock fields which can be set using the command.
-
-Debugfs's rm and kill_file command now updates the superblock free block
-and inode counts, thus keeping the filesystem consistent.
-
-Debugfs's lsdel command now takes an optional argument which allows
-the user to only see the most recently deleted files.
-
-A new command (undel) was added to debugfs which automates
-undeleting a deleted inode and linking it back to a directory.
-
-Debugfs's ls command now takes a new option, -d, which lists
-deleted directory entries.
-
-Debugfs's testb, freeb, setb, and find_free_block commands now take an
-optional count argument.
-
-Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
-be used to signal that a particular inode should not be eligible for
-tail-merging --- this is needed for programs like LILO.
-
-The findsuper (an unreleased, uninstalled utility program) has been
-improved to add extra validity checks and to add a progress meter.
-(It is still an unsupported program; the officially supported way to
-recover from a trashed partition table is to use gpart; findsuper is
-for wizards only. :-)
-
-Debugfs was fixed to compile with "configure --disable-swapfs".
-
-Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
-
-Added new translation file for Turkish.
-
-Programmer's notes:
--------------------
-
-Fix general gcc -Wall complaints.
-
-E2fsprogs (mostly) works with the dietlibc.
-
-The programming texinfo file has been expanded to include description
-of additional libext2fs functions. (Still not compeltely done, but a
-lot of the more important functions have been documented.)
-
-Added a umask structure to struct_ext2_filsys, which currently only
-modifies the behaviour of ext2fs_mkdir(), but if we add any file
-creation functions to libext2fs, we should also make sure they respect
-the umask setting.
-
-The build-rpm script was fixed to be a bit more safe.
-
-The tests' Makefile now has a way of automating test case creation
-for e2fsck, using "make testnew".
-
-Created a new function, ext2fs_dir_iterate2 which passes more
-information to the callback function (identical to the one used by
-ext2fs_dblist_dir_iterate). The directory iterator functions take a
-new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
-directory entries. If the directory entry is deleted, the callback
-function will be called with the entry paraemter set to
-DIRENT_DELETED_FILE.
-
-Added new functions, ext2fs_inode_alloc_stats and
-ext2fs_block_alloc_stats, which takes updates block/inode allocation
-statistics in the bitmaps, block group descriptors, and superblock
-when inodes or blocks are allocated or deallocated.
-
-
-E2fsprogs 1.25 (September 20, 2001)
-===================================
-
-This is primarily a bug-fix release; no new features were added, but
-there are a number of embarassing bug fixes and cleanups applied.
-
-Fix a bug mke2fs which causes stack garbage to be written to disk when
-zapping disk sectors. (This bug could cause mke2fs to core dump for
-some kernels, I suspect with security enhancement patches.)
-
-Remove unneeded #include of <linux/config.h> which was breaking
-building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
-
-Updated tune2fs man page to reflect the fact that adding or removing a
-journal doesn't require running e2fsck.
-
-Remove use of AC_REQUIRE from autoconf which had been used to prevent
-AC_CANONICAL_HOST from being called twice; unfortunately this causes
-recent autoconf to bomb out since they don't allow AC_REQUIRE to be
-used outside of autoconf macros. Fortunately, it doesn't seem to be
-necessary any more, anyway.
-
-E2fsck will now not fall back to an alternate superblock if the user
-specifies the superblock location explicitly on the command-line.
-This allows easier recovery from a situation where the primary
-superblock and block groups are slightly corrupted, but the backup
-superblocks are completely broken.
-
-Fix problem which caused compile_et and mk_cmds to blow up if
-e2fsprogs was in a directory with a pathname that contained spaces.
-
-We are now more paranoid about checking the entry in /etc/mtab to make
-sure the filesystem is really mounted, since some broken distributions
-(read: Slackware) don't initialize /etc/mtab before checking non-root
-filesystems. (Slackware also doesn't check the root filesystem
-separately, and reboot if the root filesystem had changes applied to
-it, which is dangerous and broken, but there's nothing I can do about
-that.)
-
-Make UUID library C++ friendly by adding appropriate extern "C"
-declarations and using const in the function declarations.
-
-Fix up the com_err texinfo file so that it can product a valid info
-file (previously, it could only be used to generate paper
-documentation using texinfo.tex).
-
-
-E2fsprogs 1.24a (September 2, 2001)
-===================================
-
-Fix brown-paper bug in mke2fs which caused it to segfault when
-printing the version string.

-E2fsprogs 1.24 (August 30, 2001)
-================================
-
-Revert the BLKGETSIZE64 support, since for some distributions, this
-ioctl has been used by an unofficial kernel patch to update the last
-sector on the disk, and this was causing disk corruption problems as a
-result.
-
-Mke2fs is now more careful about zapping swap space signatures and
-other filesystem/raid superblock magic values so that programs like
-mount who try to use hueristics to determine the filesystem type of a
-partition are less likely to be confused.
-
-E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
-regular file (since Andreas Dilger's on-line resizing tools will set
-its mode bits).
-
-Fixed some minor texinfo, man pages nits for spelling errors,
-texinfo warnings, etc. (Addresses Debian bug #110621.)
-
-E2fsprogs program no longer print the filesystem version number
-(i.e. 0.5b), since it only confuses people and doesn't serve any real
-purpose.
-
-E2fsck will once again compile under libc5, since it will supply its
-own version of strnlen if necesssary.
-
-mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
-when specifying the external journal device. tune2fs will also search
-devices looking for the externla journal debice when removing.
-
-E2fsprogs 1.23 (August 15, 2001)
-================================
-
-Add initial support for extended attributes (EA); e2fsck will
-correctly handle a filesystem with EA's and check the EA blocks for
-corruptions.
-
-E2fsck's symlink sanity checking has been cleaned up. It now checks
-the i_size value of fast symlinks, and checks for immutable flags
-being set of symlinks, etc.
-
-E2fsck now offers to clear inodes which are special files that have a
-non-zero i_blocks or i_size field. (The i_size field check was in the
-previous version of the code, but due to a bug it didn't offer to
-clear the inode unless i_size and i_size_high were both non-zero.)
-
-E2image can now create "raw" image files, which only contain the
-filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
-debugfs, etc., can be run directly on the raw image file.
-
-Add support for the 64-bit block device patches.
-
-Fixed bugs in creating external journals with a 1k blocksize.
-
-Add initial support for external journals (so long as the external
-journal only supports a single filesystem) in e2fsck.
-
-Remove requirement for needing to run fsck on a filesystem after
-removing a journal (either internal or external).
-
-The man pages now document how to create and manage external journals.
-
-Speed up the check of an ext3 filesystems by avoiding a needless flush
-of all of the superblock and block group descriptors.
-
-Speed up creating an internal journal using tune2fs in the case where
-the filesystem has a lot blocks already allocated.
-
-Tune2fs has been fixed to make sure that only error messages go to
-stderr, and normal message go to stdout. (Addresses Debian bug #108555)
-
-Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
-now not set the sparse_super feature. (Addresses Debian bug #108165)
-
-Add support in fsck for the filesystem type "auto".
-
-Fsck -A will not try to interpret device names for filesystems which
-have a pass number is 0. (Addresses Debian bug #106696).
-
-Fsck prints a warning message if now valid filesystems are passed to
-it. (Addresses Debian Bug #107458.)
-
-E2fsck now gives an explicit warning if there filesystem still has
-errors at the end of the run. (Addresses Debian bug #104502)
-
-E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
-reflects an error. E2fsck will also not run the orphan list if the
-filesystem contains errors, since the orphan list might be corrupted.
-
-E2fsck now prints the number of large files when given the -v option.
-
-Fixed minor memory leaks in e2fsck.
-
-Some minor man pages updates. (Addresses Debian bug #30833, #108174)
-
-
-E2fsprogs 1.22 (June 22, 2001)
-==============================
-
-Fixed a bug in e2fsck's handling of orphan inodes which are special
-files (i.e., block/character device files, named FIFO's, etc.).
-
-Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
-tune2fs to fail at adding a journal to a mounted filesystem.
-
-Fixed a few big-endian bugs in e2fsprogs
- * The directory block functions were accidentally reporting
- some directories as corrupted when they weren't.
- * If e2fsprogs is compiled --disable-swapfs, the C language
- equivalents weren't being included for big-endian platforms.
- (Fixes Debian bug #101686).
-
-Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
-
-Programmer's notes:
--------------------
-
-Use platform independent method of defining the BLKFLSBUF and FDFLUSH
-ioctls, and allow them to be defined for non-i386 platforms.
-
-The uuid.h header file is now protected against multiple inclusions.
-
-E2fsprogs is now being developed using BitKeeper. Changed the test
-scripts to deal with BK's stripping CR characgters from text files,
-and changed the top-level Makefile.in to avoid including BitKeeper
-files when generating the source tarball.
-
-
-E2fsprogs 1.21 (June 15, 2001)
-==============================
-
-Added new configure flags which allow a subset e2fsprogs to be built;
-this is most useful for boot floopies, since the resulting shared
-libraries and programs are slimmed down by removing features that
-aren't necessary for a boot floppy. The new flags that were added
-are: --disable-swapfs, which removes support for byte swapping old
-legacy PPC/68k filesystems, --disable-debugfs, which removes support
-for debugfs from the libext2fs library, --disable-imager, which
-removes support for the e2image program, and --disable-resizer, which
-removes support for resize2fs.
-
-E2fsck now prints the number of mounts or days elapsed since the last
-check when e2fsck is forced to check an otherwise clean filesystem.
-
-Tune2fs now prints an informative message about how often a filesystem
-will be checked when adding a journal to the filesystem, to remind the
-user that he/she may want to adjust those parameters using tune2fs
--c/-i.
-
-Worked around hurd brain-damage which causes e2fsck to sometimes
-believe a filesystem is the root filesystem based on device numbers
-(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
-violation).
-
-Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
-erroneous error with the -F option was specified.
-
-Fixed a ext3 recovery bug in the revoke handling; synchronized with
-ext3 0.7a.
-
-Fixed two bugs in e2fsck's handling of dup block handling, dealing
-with relatively uncommon edge cases: a directory with an indirect
-block which is claimed by another file, and when the last inode in the
-filesystem has blocks claimed by another file.
-
-E2fsck now checks to see if the i_size field of a fast symlink is too
-big, and offers to clear the symlink if so.
-
-E2fsck now checks to see if i_size_high of special files is non-zero,
-and offers to clear i_size_high.
-
-Fix e2fsck's handling of incompatible journal flags so that the user
-has chance to abort, and then has the option to clear out the journal
-entirely. (Addresses Debian bug #98527.)
-
-Fixed a bug in fsck which could cause it to core dump if a mix of
-standard and non-standard device names are used in /etc/fstab.
-(Debian bug #100559)
-
-Fixed a bug in debugfs which caused read errors when copying a file to
-not be noticed.
-
-The debugfs set_super_value command can now modify the s_lastcheck field.
-
-Fixed a bug in lsattr and chattr which was accidentally introduced in
-1.20 to support > 2GB files; both lsattr and chattr wasn't reading
-directories correctly because the change modified the layout of struct
-dirent to be incompatible with the libe2p shared library.
-
-Cleaned up the mke2fs manual page and included a discussion about why
-it's good to periodically check the filesystem even when journaling is
-enabled.
-
-Programmer's notes:
--------------------
-
-Fix general gcc -Wall complaints.
-
-The types needed by the ext2 header files are now provided by
-lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
-
-Integers are now preferred to longs when trying to find a 32-bit type
-in ext2_types.h. Also, if linux/types.h has already been defined,
-don't try to redefine the types.
-
-Fixed make depend script so that it automatically corrects the
-pathname cleanups performed by make -M, so I don't have to fix them up
-by hand.
-
-Fixed the d_loaddump test case to be more robust, and not depend on
-bash'isms.
-
-Removed debugfs's dependence on pread(), which was accidentally
-intrudced in e2fsprogs 1.20
-
-Fixed a performance bug in the libext2fs's icount routine; the size
-estimate of the icount array was incorrectly being calculated.
-
-Removed use of the badblocks compatibility functions in the e2fsprogs
-programs.
-
-Added paranoia code which protects against strange cases where /etc
-isn't on the root filesystem, or if /etc/mtab doesn't exist.
-
-The header file ext2_types.h is now installed.
-
-Autoconf is used to determine when we are on big-endian machines,
-instead of doing run-time tests, to save a few bytes of code.
-
-The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
-functions are no longer inline functions, which saves space and
-doesn't really cost any real performance.
-
-The ext2fs library no longer depends on the e2p library. (What need
-there was of it --- namely, fsetflags, was coded in-line).
-
-Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
-when the user is stupid and tries compiling the package using "make
-install" as root.
-
-Miscellaneous code cleanups:
- * Added missing files from Makefile.in's SRCS file, so that
- their dependencies would be properly calculated.
- * Removed redundant code
- * Fixed comments in code
- * Removed no-longer unneeded argsused #pragma.
-
-
-E2fsprogs 1.20 (May 20, 2001)
-=============================
-
-Add support for replaying the ext3 journal purely in user mode,
-including handling the orphaned inode list. Used code contributed by
-Andreas Dilger, with bug fixes and the orphaned inode handling done
-by Theodore Ts'o.
-
-The mke2fs and tune2fs programs can create or modify a filesystem to
-include an ext3 journal. Tune2fs also can be used to remove an ext3
-journal from a filesystem.
-
-E2fsck will now check for the existence of a linked list of orphan
-inodes in the superblock, and clear those inodes before starting the
-rest of the filesystem check (but after the journal playback).
-
-E2fsck now validates the file descriptor passed to the -C option,
-which saves against the completion bar getting written to an
-unexpected location, such as the disk being checked. (Debian
-bug/wishlist #55220)
-
-E2fsck will now bump the filesystem revision number from zero to one
-if any of the compatibility bits are set.
-
-Fixed a bug where a badly corrupted directory on a big endian system
-could cause e2fsck to die with a bus error. The
-ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
-the ext2 library now does alignment sanity checks on the rec_len field
-of the directory entry before using it.
-
-The ext2 library has been enhanced to make tune2fs safe to run on
-mounted filesystems. (Users could usually get away with using tune2fs
-on mounted filesystems before, but with the advent of ext3 and
-journaling, it became important to make tune2fs was *really* safe for
-use even when the filesystem being modified is mounted.) E2label is
-now implemented by tune2fs using an argv[0] dispatch, so that e2label
-is also now safe for use on mounted filesystems.
-
-Added a new program, e2image, which creates a backup of critical ext2
-filesystem data structures. The generated image file can be examined
-using dumpe2fs and debugfs. In the future, e2fsck will be able to use
-the image file to help recover very badly damaged filesystems.
-
-Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
-no longer cause e2fsck to bomb out. Also treat files > 2GB as being
-large file when deciding whether or not the filesystem has large files.
-
-Fixed lsattr and chattr so that they work correctly on large files.
-(Fixes Debian bug #72690.)
-
-Removed limitation in get_device_size() which imposed a one terrabyte
-filesystem limitation. (Most 2.2 kernels still have a signed int
-problem which cause 1 TB block device limitation. Fortunately, the
-kernel patches to fix this are much easier than fixing the 2TB
-limitation in the kernel. :-)
-
-A max_mount_count of zero is now treated as if no mount count were
-set. (Previously, no mount count was indicated by using -1, and a
-mount count of zero caused e2fsck to always be run.)
-
-Mke2fs supports two new filesystem types largefile and largefile4.
-
-Mke2fs now adds some randomness in s_max_mount_count so that multiple
-filesystems won't be all checked at the same time under normal
-operations.
-
-Fixed bug in the progress bar printing code which could cause e2fsck
-to core dump on an illegal filesystem.
-
-Fixed bug in fsck which could allow more than one instance of e2fsck
-to be printing a progress bar. (Debian bug #65267)
-
-Fsck using a UUID or a LABEL specifier will work even if devfs is
-compiled into the kernel and not mounted. If the pathnames in
-/proc/partitions are incorrect, fsck will search /dev for the correct
-device (using the new ext2fs_find_block_device library function).
-Fsck now also checks the RAID devices first so that they are properly
-found when they are in use. Support has also been added to support
-additional IDE disks and the DAC 960 device names. (Debian bug #94159)
-
-Fixed a bug in fsck which caused it not deal properly with 16
-byte long filesystem labels.
-
-Fsck's -t option has been made a lot more flexible. The semantics for
-what happens if a comma-separated list to fsck has been regularized,
-and it is now possible to filter what filesystems will get checked
-based what is in the filesystem's fstab entry's option field. (Debian
-bug #89483.)
-
-The dumpe2fs program can now print out the group description
-information in hex, and also prints the location of the superblock and
-block group descriptor for those block groups that have them.
-
-Mke2fs now clears the ext2 superblock before it starts creating a
-filesystem, so that the superblock magic number is only written if the
-filesystem creation process successfully completes.
-
-The debugfs program's stat command now pretty-prints the blocks used
-by an inode so that it's more compact and informative.
-
-The debugfs stats command now uses the same libe2p code (which is used
-by dumpe2fs) to print the superblock header information. This is more
-complete, and it avoids a bit of code duplication.
-
-Added a new debugfs command, set_super_value (ssv) which allows the
-user to set arbitrary superblock fields.
-
-Debugfs was extended to support inode numbers in hex (by prefixing
-them with 0x), and so that modify_inode can set the inode generation
-number. Also, there is now a new function command called logdump
-which will dump an ext3 journal.
-
-Fixed a bug in debugfs so that quitting out of the pager doesn't kill
-debugfs.
-
-Debugfs's dump command now stops immediately upon reporting a disk
-read error. (Fixed a bug in ext2fs_file_read library routine which
-caused debugfs not to stop.) (Debian bug #79163)
-
-On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
-checked before /etc/mtab is used, since /proc/mounts is more likely to
-be accurate.
-
-Added portability fixes for Solaris and Linux/ia64.
-
-Various manual pages were clarified and cleaned up. (Fixed debian
-bugs #63442, #67446, and #87216)
-
-
-Programmer's notes:
--------------------
-
-The e2fsck message printer now supports %Iu and %Ig, which will print
-out the inode's user and group owners, respectively.
-
-E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
-that no longer dependent on the system having the correct version of
-the kernel header files.
-
-Added a new function to libext2, ext2fs_find_block_device(), which
-searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
-device given its device number.
-
-Added a new function to libext2, ext2fs_sync_device, which centralizes
-all of the places which might try to use the BLKFLSBUF or FDFLUSH
-ioctls (and usually failing to define them since the system header
-files don't usually do this for us, and we're trying to avoid usage of
-kernel include files now).
-
-Added new utility programs in tests/progs: random_exercise and
-hold_inode. They aren't built by default; they're useful for
-exercising ext3 filesystem code.
-
-Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
-the filesystem close functions to only update the superblock, and to
-not touch the block group descriptors. Needed by tune2fs when
-modifying a mounted filesystem.
-
-Got rid of struct ext2fs_sb and replaced it with the standard struct
-ext2_super_block from include/linux/ext2_fs.h. Note: this may break
-source (but not binary) compatibility of some users of the ext2
-library. Those applications should just simply do a global search and
-replace of struct ext2fs_sb with struct ext2_super_block, and include
-the new header file <ext2fs/ext2_fs.h> which defines it.
-
-The ino_t type has been renamed ext2_ino_t to protect applications
-that attempt to compile -D_FILE_OFFSET_BITS=64, since this
-inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
-unexpected ABI change.
-
-The Makefiles have been reworked so that "make check" can be run from
-the top-level Makefile.
-
-Fix general gcc -Wall complaints and removed dead code.
-
-Remove use of NOARGS, because we assume everyone does ANSI C these
-days.
-
-Added build-rpm script from sct.
-
-New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
-to support e2image.
-
-New function ext2fs_flush_icache which must be called if the
-application program modifies the inode table blocks without going
-through ext2fs_write_inode() interface.
-
-New ext2fs_check_mount_point() function, which will return the mount
-point of a device if mounted.
-
-The io_channel abstraction now has an optional interface,
-io_channel_write_range, which allows specific byte ranges to be
-written.
-
-The unix_io IO channel now supports write-through caching, so that
-journal creation is more efficient.
-
-Added x86 assembly language routines to support byte swapping, to
-reduce executable size.
-
-Fixed bug in the utility program subst so that it's possible to
-replace a substitution variable with a zero-length string.
-
-Fixed numbering e2fsck pass1 problem numbers; an extra zero had
-slipped into some of the problem number.
-
-E2fsprogs 1.19 (July 13, 2000)
-==============================
-
-Release the resize2fs program since the timeout before it could
-be released under the GPL has finally expired.
-
-Add experimental support needed for the ext2 compression patches.
-This requires compiling e2fsprogs with the --enable-compression flag
-to the configure script.
-
-Added ext3 journalling support. E2fsck will run the journal (if
-necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
-installed as a symlink to e2fsck. Fsck has been taught about ext3,
-and treats it the same as ext2 in terms of the progress bar logic.
-Dumpe2fs will display the superblock journaling information if the
-filesystem has a journal. The ext2 library will now permit opening an
-ext3 filesystem with the recovery flag set. This is necessary for
-on-line dump's to work correctly, but there may be issues with this
-working well since ext3 is much less agressive about syncing blocks to
-the filesystem, since they're safe on the journal.
-
-Tune2fs and e2fsck have been changed to allow the mount_count check to
-be disabled by setting max_mount_count to -1. (This was already
-supported by the kernel.)
-
-Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
-are used for ext3 as well.
-
-Added internationalization support for e2fsprogs; must be enabled
-by passing --enable-nls to configure.
-
-Always use the provided ext2fs header files to insulate ourselves from
-kernel version changes. Which include files are used by e2fsprogs
-have also been cleaned up to improve portability.
-
-Limit the number of times that e2fsck updates the progress bar so that
-people who are booting using a 9600 baud console don't get swampped by
-too many updates.
-
-Improved the loop detection algorithm in e2sck's pass #3 so that it is
-much, much faster for large filesystems with a large number of
-directories.
-
-The memory footprint for e2fsck is now slightly smaller than before.
-
-E2fsck now checks if special devices have a non-zero size, and offers
-to clear the size field if it finds such an inode.
-
-E2fsck now checks if special devices have the append-only flag set,
-and offers to clear the inode.
-
-E2fsck now properly handles some "should never fail" cases during a
-bitmap copy in pass5.
-
-E2fsck now properly prints control characters in filenames as ^A .. ^Z.
-
-E2fsck now calculates the correct location of the backup superblock in
-the case of filesystem blocksizes > 1k.
-
-Fixed a bug in e2fsck's calculation of the number of inodes_per_block
-which normally didn't cause problems under most filesystem parameters,
-but could cause a valid superblock to be rejected in extreme cases.
-Other checks for validating superblock values were made more
-stringent.
-
-Added non-destructive write testing to the badblocks program, courtesy
-of David Beattie. The badblocks also now has an option to input the
-current set of bad blocks, so that known bad blocks are skipped to
-speed up the badblocks test. There is also a persistent rescan
-feature which causes badblocks to run until it has completed some
-number of passes without discovering any new bad blocks.
-
-Badblocks now checks to see if the device is mounted and refuses to do
-the tests involving writing to the device if it is mounted. Also,
-badblocks now allows the number of blocks to be checked to be
-defaulted to the size of the partition.
-
-Fixed a bug in fsck which didn't allow non-root users to be able to
-check filesystems if there were any LABEL= or UUID= entries in
-/etc/fstab.
-
-The Hurd doesn't support the filetype filesystem feature. The mke2fs
-program now makes sure that for the Hurd, the filestype feature is
-turned off. E2fsck will check to see if the filetype feature is
-turned on for Hurd filesystems, and offer to turn off the feature.
-
-Mke2fs now has a safety check to make sure the number of blocks do not
-exceed 32 bits even on a 64 bit platform.
-
-Really fixed a bug in fsck to allow "fsck -As" to run interactive
-fsck's. (For those people who like to do interactive fsck's in the
-/etc/rc scripts!?!)
-
-Debugfs has a few new features: the rdump command, which will do a
-recursive dump of a directory and all of its contents, and the lcd
-command which does a local chdir (much like the ftp command of the
-same name). In addition, the debugfs program and the open_filesystem
-command now takes three new options: -b and -s, which allows the
-blocksize and superblock location to be specified, and the -c option
-which is used in catastrophic situations where the block group
-descriptors are corrupt. If the -c option is specified, debugfs will
-skip trying to read in the block and inode bitmaps.
-
-Debufs's lsdel command was fixed to handle bad blocks in the inode
-table.
-
-A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
-4 digit years.
-
-General improvements in error messages
-
- - Mke2fs prints a sane error message if the partition size is zero
- (usually because the partition table wasn't reread by the
- kernel due to the partition being busy), instead of "invalid
- argument passed to ext2 library while initializing superblock".
-
- - Fsck now prints more self-explanatory message if an invalid UUID=
- or LABEL= specification is passed to it.
-
-UUID library changed to use the LGPL.
-
-Fixed a bug in the UUID library where very rapid calls to the
-time-based UUID generator could cause duplicate UUID's to be returned.
-This was not a problem for e2fsprogs, but it could be a problem for
-other users of the library.
-
-Make the UUID library more robust in the face of missing or an
-improper /dev/urandom or /dev/random files.
-
-Added some random portability fixes for Solaris.
-
-Some minor man page updates.
-
-Fixed a memory leak in the ss library.
-
-
-Programmer's notes:
--------------------
-
-We now try to use lseek64 and open64 from the LFS if possible.
-
-The 3rd parameter in e2p's print_flags is now a flags word, instead of
-a boolean option.
-
-The mark and unmark bitmap functions now return the previous state of
-the bit that was being changed, which is useful for some speed
-optimizations.
-
-The following functions have been added to enhance the badblocks list
-handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
-ext2fs_badblocks_equal.
-
-The ext2 header files now have the latest journalling fields to the
-superblock.
-
-The ext2fs_mkdir function in libext2fs now properly backs out of error
-conditions robustly.
-
-Cleaned up makefiles:
- - to cleanly compile with the -j flag.
- - so distclean removes all generated files.
- - so in case of an error while installing header files, the make aborts.
-
-Fix test_script so that it works correctly when compiling in the
-source directory.
-
-The random UUID generation routine has been made slightly better in
-the case where /dev/random doesn't exist. (Use of randomly-based UUID
-is still not recommended if /dev/random doesn't exist, however; it's
-better to use the time/ethernet MAC address UUID in this case.)
-
-Clean up the build process so it's more friendly in case of missing
-directories.
-
-The ext2fs header file can now be #include'd into C++ programs.
-
-The e2p.h header file is now installed.
-
-Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
-
-
-
-E2fsprogs 1.18 (November 10, 1999)
-==================================
-
-Fix a core dumping bug in e2fsck if an imagic inode is present or
-(more rarely) if the filesystem is badly corrupted enough that e2fsck
-has to restart pass 1 processing. E2fsck now closes the filesystem
-before freeing a large number of its data structures, so in the case
-of future memory faults, at least the fixed filesystem will be fully
-written out.
-
-If a filesystem doesn't support imagic inodes, and e2fsck discovers an
-imagic inode, it will offer to clear the imagic flag.
-
-E2fsck will now offer to clear the immutable flag on special files
-(device/socket/fifos) when running it in non-preen mode.
-
-E2fsck will now set the filetype when creating /lost+found, and when
-connected orphaned inodes to /lost+found.
-
-Debugfs's ncheck and icheck commands now handles the case where there
-are bad blocks in the inode table without bombing out.
-
-The badblocks list processing code has been made more efficiently for
-appending a large number of (ordered) badblocks to the badblocks list.
-
-Some minor man page updates.
-
-Fsck now allows interactive e2fsck's when using fsck -As (not a common
-mode, but some people like to do this in boot scripts for silly reasons).
-
-Programmer's notes:
--------------------
-
-The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
-with the problem code convention.
-
-The badblocks list regression test program has been updated to work
-with previously made API name changes.
-
-The ext2fs_free() command now uses the new badblocks API to avoid
-using the compatibility layer.
-
-Added new regression test cases; the run_e2fsck test script now
-supports the ability for a test case to run a prepratory command
-before running e2fsck.
-
-E2fsprogs 1.17 (October 26, 1999)
-=================================
-
-Fixed nasty typo in fsck which caused parallelized fsck's to go into an
-infinite loop.
-
-Fixed a bug in fsck where it used strncmp to compare a binary UUID,
-thus potentially causing problems if a binary UUID contained a NULL
-character.
-
-E2fsck now uses stricter checks for directory entries in pass 2:
-zero-length filenames are not allowed; neither are 8 byte long
-directory entries.
-
-The debugfs "dirty" command now clears the filesystem valid bit.
-(Previously this just set the dirty-as-in-needs-writing-out-to-disk
-bit in the in-core superblock image. The new functionality is more
-what the user expects, and is more useful.)
-
-Added a debugging hook to test parallel fsck; if the environment
-variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
-will be checked in parallel when they normally would not be.
-
-Programmer's notes:
--------------------
-
-Fixed some #ifdef's for compilation under the Hurd OS.
-
-Fixed minor W2K compatibility problems.
-
-Fixed some miscellaneous GCC warnings.
-
-
-E2fsprogs 1.16 (October 22, 1999)
-=================================
-
-Fixed a race condition bug in fsck; when printing a progress bar, if
-checking multiple filesystems in parallel, it was possible for fsck to
-send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
-handler, which would cause it to terminate with a signal 10.
-
-E2fsck now properly handles filesystems that have the
-INCOMPAT_FILETYPE feature turned on. It can be used to convert a
-filesystem into using or not using FILETYPE feature.
-
-E2fsck now properly handles filesystems that have the IMAGIC feature
-turned on (this is used on Linux AFS servers).
-
-The mke2fs program now creates filesystems that have the filetype and
-sparse_superblock features enabled by default, unless it is run on a
-pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
-so there is now a new flag -O which allows the user to specify with
-which features she would like to create the filesystem; "mke2fs -O
-none" will create a filesystsem compatible with 2.0 kernels.
-
-The tune2fs program now has a -O option which allows the user to set
-and reset "safe" filesystem features. Currently, the only ones which
-allows to be modified are the filetype and sparse_superblock features.
-Note setting or clearing either feature will require running e2fsck on
-the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
-requires that there is enough free space on the filesystem for the
-extra superblocks which will be created by e2fsck.)
-
-Debugfs can now set and print filesystem features in the superblock
-using the "features" command. Dumpe2fs will print out the complete
-set of features when listing the superblock.
-
-Dumpe2fs has new options -f (force) and -h (header-only).
-
-Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
-message to come up. This could happen when decrementing or
-incrementing a link count could result in an overflow.
-
-Fixed a bug in e2fsck where the block count on the lost+found
-directory would not be properly incremented when the directory was
-expanded to the point where an indirect block needed to be allocated.
-
-E2fsck now makes some additional sanity checks on the superblock to
-avoid crashing or giving a memory allocation error if some of the
-values in the superblock are unresonable (but the superblock otherwise
-looks valid).
-
-Fixed a bug in e2fsck where a very badly corrupted filesystem might
-require two passes to completely fix the filesystem. This happened if
-an inode claimed blocks that was part of the filesystem metadata
-(typically, when garbage was written into an inode table or indirect
-block, since this kind of filesystem corruption normally doesn't
-happen otherwise).
-
-On the Alpha, glibc declares st_flags although it isn't actually used;
-the configure script was improved to detect this case so that
-e2fsprogs can avoid using the non-functional stat field.
-
-The manual pages were updated to use a more consistent formatting
-style consistent with standard Unix man pages. Mke2fs's man page
-added documentation for a few previously undocumented options.
-
-Fixed minor display bugs in tune2fs and mke2fs.
-
-Programmer's notes:
--------------------
-
-Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
-
-Added features to parse and print feature strings into the e2p library.
-(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
-
-ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
-whose directory entries contain proper filetype information if the
-filesystem supports it.
-
-ext2fs_link() now uses the low 3 bits of its flags parameter to pass
-the directory entry filetype information. This is used to set the
-directory entry filetype information if the filesystem supports it.
-
-Fixed a bug in ext2fs_expand_dir() where the block count in a
-directory's inode would not be properly incremented when the directory
-was expanded to the point where an indirect block needed to be
-allocated.
-
-
-E2fsprogs 1.15 (July 18, 1999)
-==============================
-
-Add configuration checks so that e2fsprogs will compile cleanly on
-Linux 2.3 kernels that have renamed i_version to i_generation.
-
-E2fsck now prints a progress/completion bar (and not just a simple
-spinner) if the -C0 option is requested or if it receives a SIGUSR1
-signal. Fsck will automatically manage the (potentially muliple)
-e2fsck processes to print completion bars if it is given a -C option,
-with the right thing happening if multiple filesystems are being
-checked in parallel.
-
-Mke2fs now has better automatic hueristics to determine the filesystem
-parameters to be used for a particular filesystem. Added a new option
--T which allows the user to specify how the filesystem is to be used,
-which helps mke2fs do a better job selecting the filesystem parameters.
-
-Mke2fs now creates revision 1 filesystems by default, and with the
-sparse superblock feature enabled. The sparse superblock feature is
-not understood by Linux 2.0 kernels, so they will only allow read-only
-mounts of filesystems with this sparse superblocks.
-
-Fix bug where if /dev/null couldn't be opened (should never happen),
-e2fsck would hang in a tight loop.
-
-Make e2fsck handle the case where /lost+found isn't a directory.
-
-E2fsck now uses mallinfo if it exists to get accurate statistics about
-its memory usage.
-
-Fix bug in e2fsck where it wouldn't check to see if a disconnected
-inode had any problems before connecting it to /lost+found.
-
-Add check to e2fsck so it makes sure that total number of inodes in
-the filesystem is a sane number.
-
-Fix fencepost error when clearing an the end of the block bitmap which
-caused the last block in the bitmap not to get cleared.
-
-Cleaned up a number of messages in e2fsck:
- * The message "Group's #'s copy of the group descriptor..."
- was fixed so that the correct number would be displayed.
- * Added missing space in the "disk write-protected" error messsage
- * Cleaned up the error message printed when a non-interactive
- e2fsck needs to abort a check because the filesystem
- appears to be mounted.
-
-Added a new command-line utility, uuidgen, which will create and print
-a UUID.
-
-Make debugfs's icheck command more robust by checking to make sure an
-inode has valid blocks before interarting over the inode's blocks.
-
-UUID generation now uses a random-based scheme whenever possible to
-prevent potential privacy problems.
-
-Man pages for all of the UUID functions in the lirbary were added.
-
-Fixed bug in fsck so it won't coredump if a filesystem not in
-/etc/fstab is given to it.
-
-Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
-that most of the other mount utilities understands.
-
-Mke2fs will make a filesystem even if it appears mounted if the force
-option is given.
-
-Dumpe2fs has new command-line options which allow a filesystem expert
-to specify the superblock and blocksize when opening a filesystem.
-This is mainly useful when examining the remains of a toasted
-filesystem.
-
-The badblocks program has been updated to display correctly on disks
-with large block numbers.
-
-The badblocks program no longer gives spurious errors when errors
-occur on non-block boundaries, which is common if the blocksize is
-larger than 1k.
-
-Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
-MKE2FS_SYNC environment variable is set. This is to work around a VM
-bug in the 2.0 kernel. I've heard a report that a RAID user was able
-to trigger it even using a 2.2 kernel, but hopefully it will not be
-needed for most Linux 2.2 users.
-
-Fixed miscellaneous documentation and man pages.
-
-Programmer's notes:
--------------------
-
-Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
-in e2fsck's pass1.c really should have been static.
-
-The return value of the uuid_compare() function was changed to make it
-match with the convetions used by strcmp, memcmp, and Paul Leach's
-UUID sample document.
-
-The "make depend" process has now been made more automated; it now
-automatically word-wraps the dependencies, and only replaces source
-Makefile.in if there has been a change in the dependencies. Also, a
-top-level "make depend" now recurses through all the subdirectories
-automatically.
-
-The Makefile in .../util has been changed so that subst is built using
-the native C compiler during a cross-compilation, since the subst
-program is only used during the build process. Also add an explicit
-rule to build util/subst by cd'ing to the correct directory and
-running Makefile.
-
-The man directories are defined in terms mandir, so that the configure
-script can override the location of the manual pages.
-
-The config files have been updated to recognize new machine types for
-both the i386 and alpha families.
-
-Fsck has been modified so that it will accurately create an
-fsck_instance even when the noexecute flag is set. This allows for
-accurate debugging of the fsck pass structure. Also, when the verbose
-flag is given twice, fsck will print debugging information about when
-fsck is waiting for jobs to finish.
-
-
-E2fsprogs 1.14 (January 9, 1999)
-================================
-
-Fix the fstab parsing code so that it can handle blank lines and
-comment characters. Also, missing pass numbers need to be treated as
-zero.
-
-Fixed a bug in e2fsck where under some circumstances (when e2fsck
-needs to restart processing after fixing an egregious inconsistency)
-it would try to access already freed memory.
-
-E2fsck now prints non-printable characters in directory entries and
-pathnames using '^' and 'M-' notation.
-
-Fixed chattr so that it will ignore symbolic links when doing
-recursive descent traversals. For both chattr and lsattr, no longer
-print the version string unless the -V option is given.
-
-Allow the system administrator to directly specify the number of
-inodes desired in the filesystem, for some special cases where this is
-necessary.
-
-Fix portability problems so that e2fsprogs can be compiled under Linux
-1.2 systems and Solaris systems.
-
-Update the config.guess file with a more recent version that will
-identify newer Linux platforms.
-
-Programmer's notes
-------------------
-
-Ext2fs_read_inode and ext2fs_write_inode will now return an error if
-an inode number of zero is passed to them.
-
-E2fsprogs 1.13 (December 15, 1998)
-==================================
-
-Fixed a bug in debugfs where an error messages weren't getting printed
-when the ext2 library routines to read inodes returned errors in the
-stat, cmri and rm commands.
-
-Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
-provided, it won't create an inode table smaller than the minimum
-number of inodes required for a proper ext2 filesystem.
-
-Fsck now parses the /etc/fstab file directly (instead of using
-getmntent()), so that it can distinguish between a missing pass number
-field and pass number field of zero. This caused problems for
-diskless workstations where all of the filesystems in /etc/fstab have
-an explicit pass number of zero, and fsck could not distinguish this
-from a /etc/fstab file with missing pass numbers.
-
-E2fsck will create a /lost+found directory if there isn't one in the
-filesystem, since it's safer to create the lost+found directory before
-it's needed.
-
-Fixed e2fsck so that it would detect bogus immutable inodes which
-happen to be sockets and FIFO files, and offer to clear them.
-
-If a filesystem has multiple reasons why it needs to be checked, and
-one of the reasons is that it is uncleanly mounted, e2fsck will print
-that as the reason why the filesystem is being checked.
-
-Cleaned up the output routines of mke2fs so that it doesn't overflow
-an 80 column display when formating really big filesystems.
-
-Added a sanity check to e2fsck to make sure that file descriptors 0,
-1, 2 are open before opening the hard disk. This avoids a problem
-where a broken program might exec e2fsck with those file descriptors
-closed, which would cause disastrous results if the kernel returns a
-file descriptor for the block device which is also used by FILE *
-stdout.
-
-Fixed up the e2fsck progress reporting functions so that the values
-reliably reach 100% at the completion of all of the e2fsck passes.
-
-Fixed minor documentation bugs in man pages and usage messages.
-
-Programmer's notes:
--------------------
-
-Fixed a number of lint warnings in the ext2fs library and potential
-portability problems from other OS's header files that might define
-CPP macros for names like "max" and "min".
-
-ext2fs_badblocks_list_add() has been made more efficient when it needs
-to grow the bad blocks list.
-
-Fixed a bug in e2fsck which caused it to dereference a freed pointer
-just before exiting.
-
-Fixed the substition process for generating the mk_cmds and compile_et
-scripts so that they will work outside of the build tree.
-
-Add sanity check to e2fsck so that if an internal routine
-(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
-and causing a core dump. This should never happen, but...
-
-E2fsprogs 1.12 (July 9, 1998)
-==================================
-
-E2fsprogs now works with glibc (at least with the version shipped wtih
-RedHat 5.0). The ext2fs_llseek() function should now work even with
-i386 ELF shared libraries and if llseek() is not present. We also
-explicitly do a configure test to see if (a) llseek is in libc, and
-(b) if llseek is declared in the system header files. (See standard
-complaints about libc developers don't understand the concept of
-compatibility with previous versions of libc.)
-
-The ext2fs library now writes out the block group number in each of
-the superblock copies. This makes it easier to automatically
-determine the starting block group of the filesystem when the block
-group information is trashed.
-
-Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
-which means that e2fsprogs will ignore the high 8 bits of the
-directory entry's name_len field, so that it can be used for other
-purposes.
-
-Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
-E2fsprogs will now support filesystems with 64-bit sized files.
-
-Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
-
-Added new program "e2label", contributed by Andries Brouwer. E2label
-provides an easy-to-use interface to modify the filesystem label.
-
-Fixed bug so that lsattr -v works instead of producing a core dump.
-
-Fixed a minor bug in mke2fs so that all groups with bad superblock
-backup blocks are printed (not just the first one).
-
-Mke2fs will check the size of the device, and if the user specifies a
-filesystem size larger than the apparent size of the device it will
-print a warning message and ask if the user wants to proceed.
-
-E2fsck has a new option -C, which sends completion information to the
-specified file descriptor. For the most part, this is intended for
-programs to use, although -C 0 will print a spinning character to the
-stdout device, which may be useful for users who want to see something
-happening while e2fsck goes about its business.
-
-Fixed a bug in e2fsck which could cause a core dump when it needs to
-expand the /lost+found directory, and sometimes the bitmaps haven't
-been merged in. Also fixed a related bug where ext2fs_write_dir_block
-was used to write out a non-directory block. (Which would be bad on a
-non-Intel platform with byte swapping going on.)
-
-Fixed bug in e2fsck where it would print a "programming error" message
-instead of correctly identifying where a bad block was in used when
-the bad block was in a non-primary superblock or block group
-descriptor. Also fixed a related bug when sparse superblocks are in
-use and there is a bad block where a superblock or block group
-descriptor would have been in a group that doesn't include a
-superblock.
-
-Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
-the block group descriptor table is corrupt, it was possible to try to
-allocate a huge array, fail, and then abort e2fsck.
-ext2fs_get_num_dirs() now sanity checks the block group descriptor,
-and subsitutes reasonable values if the descriptors are obviously bogus.
-
-If e2fsck finds a device file which has the immutable flag set and the
-i_blocks beyond the normal device number are non-zero, e2fsck will
-offer to remove it, since it's probably caused by garbage in the inode
-table.
-
-When opening a filesystem, e2fsck specially checks for the EROFS error
-code, and prints a specific error message to the user which is more
-user friendly.
-
-If the filesystem revision is too high, change the e2fsck to print
-that this is either because e2fsck is out of date, or because the
-superblock is corrupt.
-
-E2fsck now checks for directories that have duplicate '.' and '..'
-entries, and fixes this corruption.
-
-E2fsck no longer forces a sync of the filesystem (with attendant sleep
-calls) at all times. The ext2fs_flush() function now performs a sync
-only if it needed to write data blocks to disk.
-
-Fixed a minor bug in e2fsck's pass1b's file cloning function, where
-certain errors would not be properly reported.
-
-Updated and expanded a few points in the man pages which users
-complained wheren't explicit enough.
-
-Added special case byte-swapping code if compiling on the PowerPC, to
-accomodate the strange big-endian variant of the ext2 filesystem that
-was previously used on the PowerPC port.
-
-
-Programmer's notes:
--------------------
-
-Removed C++ keywords from the ext2fs libraries so that it could be
-compiled with C++.
-
-E2fsck's internal organization has now been massively reorganized so
-that pass*.c don't have any printf statements. Instead, all problems
-are reported through the fix_problem() abstraction interface. E2fsck
-has also been revamped so that it can be called as a library from a
-application.
-
-Added new fileio primitives in libext2fs for reading and writing
-files on an unmounted ext2 filesystem. This interface is now used by
-debugfs.
-
-Added a new libext2fs function for mapping logical block numbers of
-a file to a physical block number.
-
-Added a new libext2fs function, ext2fs_alloc_block(), which allocates
-a block, zeros it, and updates the filesystem accounting records
-appropriately.
-
-Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
-sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
-
-The libext2fs functions now use a set of memory allocation wrapper
-functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
-instead of malloc, free, and resize. This makes it easier for us to
-be ported to strange environments where malloc, et. al. aren't
-necessarily available.
-
-Change the libext2fs fucntion to return ext2-specific error codes
-(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
-and depending on the existence of system error codes (such as EEXIST
-and ENOENT).
-
-Renamed io.h to ext2_io.h to avoid collision with other OS's header
-files.
-
-Add protection against ext2_io.h and ext2fs.h being included multiple
-times.
-
-The types used for memory lengths, etc. have been made more portable.
-In generla, the code has been made 16-bit safe. Added Mark
-Habersack's contributed DOS disk i/o routines.
-
-Miscellaneous portability fixes, including not depending on char's
-being signed.
-
-The io_channel structure has a new element, app_data, which is
-initialized by the ext2fs routines to contain a copy of the filesystem
-handle.
-
-ext2fs_check_directory()'s callback function may now return the error
-EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
-really do the checking, despite the presence of the callback function.
-
-
-E2fsprosg 1.11 (June 17, 1997)
-==============================
-
-Fixed e2fsck to detect (previously ignored) conflicts between the
-superblock or block group descriptors and block bitmaps, inode
-bitmaps, and inode tables.
-
-Fixed bug in e2fsck so that when the message printed out when a block
-or inode bitmap conflicts with other data, it has the correct group
-number.
-
-Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
-to badblocks. This meant that not all of the filesystem was being
-tested for bad blocks!
-
-Fixed an array boundary overrun case which cropped up in
-ext2fs_badblocks_list_test when a user tried running "mke2fs -c
--b 4096".
-
-Adjusted the number of columns printed by mke2fs when displaying the
-superblock backups to avoid running over 80 columns when making a
-really big filesystem.
-
-Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
-dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
-fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
-
-Programmer's notes:
--------------------
-
-Fixed install rule in lib/ss so that ss_err.h is actually getting
-installed.
-
-Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
-bassed back to the caller.
-
-Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
-setting the current inode number (which meant this function wasn't
-working at all).
-
-Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
-blocks in the bitmap when increasing the size of the bitmap.
-
-Changed the initial number of blocks allocated by ext2fs_init_dblist()
-to be more realistic.
-
-Added a new function ext2fs_allocate_group_table, which sets up the
-group descriptor information (and allocates inode and block bitmaps,
-and inode tables for a particular group). The function was created by
-factoring out code form ext2fs_allocate_tables().
-
-Added a new function ext2fs_move_blocks which takes a bitmap of the
-blocks to be moved, and moves them to another location on the
-boardboard.
-
-Make the unix_io channel's io_channel_flush implementation calls sync()
-to to flush the kernel buffers to disk.
-
-Added a new function ext2fs_dblist_count returns the number of
-directory blocks in dblist.
-
-
-E2fsprogs 1.10 (April 24, 1997)
-===============================
-
-Mke2fs once again defaults to creating revision #0 filesystems, since
-people were complaining about breaking compatibility with 1.2 kernels.
-Warning messages were added to the mke2fs and tune2fs man pages that
-the sparse superblock option isn't supported by most kernels yet (1.2
-and 2.0 both don't support parse superblocks.)
-
-Added new flag to mke2fs, -R <raid options>, which allows the user to
-tell mke2fs about the RAID configuration of the filesystem. Currently
-the only supported raid option is "stride" which specifies the width
-of the RAID stripe.
-
-Fixed bug in e2fsck where pass1b would bomb out if there were any
-blocks marked bad in the inode table.
-
-Fixed rare bug in mke2fs where if the user had a very unlucky number
-of blocks in a filesystem (probability less than .002) the resulting
-filesystem would be corrupt in the last block group.
-
-Fixed bug where if e2fsck tried to allocate a block to fix a
-filesystem corruption problem and the filesystem had no free blocks,
-ext2fs_new_block() would loop forever.
-
-The configure script now checks explicitly to see if "-static" works,
-since that can't be assumed to be true --- RedHat doesn't install
-libc-static by default.
-
-Fixed bug in libext2's block iterator functions where under some
-cirmcustances, file with holes would cause the bcount parameter to the
-callback function to be incorrect. This bug didn't affect any of
-e2fsprogs programs, but it was discovered by Paul Mackerras, the
-author of the PPC boot loader.
-
-Removed use of static variables to store the inode cache in libext2fs.
-This caused problems if more than one filesystem was accessed via
-libext2fs (static variables in libraries are generally a bad idea).
-Again, this didn't affect e2fsprogs programs, but it was discovered by
-Paul Mackerras.
-
-Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
-will compile cleanly with 1.2.13 kernels (even with a.out shared
-libraries!)
-
-Programmer's notes:
--------------------
-
-Added new functions to duplicate an ext2 filesystem handle, and its
-associated substructure. New functions: ext2fs_dup_handle(),
-ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
-Other structures, such as the io_channel and the inode_cache, now have
-a ref count so that they only get freed when they are no longer used
-by any filesystem handle. (These functions were added as part of the
-development effort for an ext2 resizer).
-
-E2fsprogs 1.09 (April 14, 1997)
-===============================
-
-Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
-accidentally introduced in the 1.08 release. The overhead calculation
-was accidentally removed, which caused ext2fs_initialize() to not
-notice when the filesystem size needed to be adjusted down because
-there wasn't enough space in the last block group.
-
-Fixed bug in version parsing library routine; it was always parsing
-the library version string, instead of using the passed-in string.
-
-Clarified chattr man page.
-
-E2fsprogs 1.08 (April 10, 1997)
-===============================
-
-E2fsck 1.07 was very slow when checking very large filesystems with a
-lot of files that had hard links (i.e., news spools). This was fixed
-by seriously revamping the icount abstraction. Added a formal test
-suite for the icount abstraction.
-
-Debugfs now has a "-l" option to the "ls" command, which lists the
-inode number, permissions, owner, group, size, and name of the files
-in the directory.
-
-Fix a bug in e2fsck where when a directory had its blocks moved to
-another location during the pass 1b processing, the directory block
-list wasn't updated, so pass 2 wouldn't check (and correct) the
-correct directory block.
-
-E2fsck will now treat inodes which contain blocks which are claimed by
-the filesystem metadata by treating them as multiply claimed blocks.
-This way, the data in those blocks can be copied to a new block during
-the pass 1b--1d processing.
-
-E2fsck will attempt to determine the correct superblock number and
-display it in the diagnostic and warning messages if possible.
-
-Add support for a new (incompatible) feature, "sparse_super". This
-feature reduces the number of blocks which contain copies of backup
-superblocks and block group descriptors. (It is only an incompatible
-feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
-support a new -s option; e2fsck will recognize filesystems built with
-this feature turned on.
-
-E2fsck now checks the library to make sure is the correct version,
-using new library functions. (This helps to diagnose incorrectly
-installed e2fsprogs distributions.)
-
-Dumpe2fs now prints more information; its now prints the the
-filesystem revision number, the filesystem sparse_super feature (if
-present), the block ranges for each block group, and the offset from
-the beginning of the block group.
-
-Mke2fs now distributes the inode and block bitmap blok so that the
-won't be concentrated in one or two disks in RAID/striping setups.
-Also, if the user chooses a 2k or 4k block group, mke2fs will try to
-choose the largest blocks per group that be chosen. (For 2k blocks,
-you can have up to 16384 blocks/group; for 4k blocks, you can have up
-to 32768 blocks/group.) Previously mke2fs would not allow
-specification of more than 8192 blocks per group, even if you were
-using a 2k or 4k block group.
-
-Programmer's notes:
--------------------
-
-Added a new function ext2fs_create_icount2() which takes a "hint"
-argument. This hint argument presets the icount array with the list
-of inodes which actually need to be in the icount array. This really
-helps to speed up e2fsck.
-
-Added a new function ext2fs_icount_validate() which checks the rep
-invariant for the icount structure. This is used mostly for testing.
-
-The error mesasage given when a bad inode number is passed to
-test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
-EXT2FS_UNMARK_ERROR).
-
-Added a new function ext2fs_set_dir_block which sets the block of a
-dblist entry, given the directory inode and blockcnt.
-
-Added a new function ext2fs_get_library_version() which returns the
-current library version, and ext2fs_parse_version_string() which
-returns a version number based on a e2fsprogs version string.
-
-The icount functions will return EINVAL if the passed in inode number
-is out of bounds.
-
-E2fsprogs 1.07 (March 9, 1997)
-==============================
-
-E2fsck is now uses much less memory when checking really large
-filesystems (or rather, filesystems with a large number of inodes).
-Previously a filesystem with 1 million inodes required 4 megabytes of
-memory to store inode count statistics; that storage requirement has
-now been reduced to roughly half a megabyte.
-
-E2fsck can now properly deal with bad blocks appearing inside the
-inode table. Instead of trying to relocate the inode table (which
-often failed because there wasn't enough space), the inodes in the bad
-block are marked as in use.
-
-E2fsck will automatically try to use the backup superblocks if the
-primary superblocks have a bad magic number or have missing meta-data
-blocks (or meta-data blocks which are out of range).
-
-E2fsck's pass 3 has been made more efficient; most noticeable on
-filesystems with a very large number of directories.
-
-Completely revamped e2fsck's system of printing problem reports. It
-is now table driven, to make them more easily customizeable and
-extendable. Error messages which can be printed out during preen mode
-are now one line long.
-
-Fixed e2fsck's filesystem swapping code so that it won't try to swap
-fast symbolic links or deleted files.
-
-Fixed e2fsck core dumping when fixing a filesystem which has no
-directories (not even a root directory).
-
-Added a check to e2fsck to make sure that the length of every
-directory entry is a multiple of 4 (since the kernel complains if it
-isn't).
-
-Added a check to e2fsck to make sure that a directory entry isn't a
-link to the root directory, since that isn't allowed.
-
-Added a check to e2fsk to now make sure the '.' and '..' directory
-entries are null terminated, since the 2.0 kernel requires it.
-
-Added check to write_bitmaps() to make sure the superblock doesn't get
-trashed if the inode or block bitmap is marked as being block zero.
-
-Added checking of the new feature set fields in the superblock, to
-avoid dealing with new filesystem features that this package wasn't
-set up to handle.
-
-Fixed a fencepost error in ext2fs_new_block() which would occasionally
-try to allocate a block beyond the end of a filesystem.
-
-When the UUID library picks a random IEEE 802 address (because it
-can't find one from a network card), it sets the multicast bit, to
-avoid conflicting with a legitimate IEEE 802 address.
-
-Mke2fs now sets the root directory's owner to be the real uid of the
-user running mke2fs. If the real uid is non-zero, it also sets
-the group ownership of the root directory to be the real group-id of
-the user running mke2fs.
-
-Mke2fs now has more intelligent error checking when it is given a
-non-existent device.
-
-When badblocks is given the -vv option, it now updates the block that
-it is currently testing on every block.
-
-Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
-currently correctly if PATH wasn't already set.
-
-Shared libraries now built with dependencies. This allows the shared
-library files to be used with dlopen(); it also makes the transition
-to libc 6 easier, since ld.so can tell which libc a particular shared
-library expects to use.
-
-Programmer's notes:
--------------------
-
-Added new abstraction (defined in dblist.c) for maintaining a list of
-blocks which belongs to directories. This is used in e2fsck and other
-programs which need to iterate over all directories.
-
-Added new functions which test to see if a contiguous range of blocks
-(or inodes) are available. (ext2fs_*_bitmap_range).
-
-Added new function (ext2_inode_has_valid_blocks) which returns true if
-an inode has valid blocks. (moved from e2fsck code).
-
-Added new function (ext2fs_allocate_tables) which allocates the
-meta-data blocks as part of initializing a filesystem. (moved from
-mke2fs code).
-
-Added a new I/O manager for testing purposes. It will either allow a
-program to intercept I/O requests, or print debugging messages to
-trace the activity of a program using the I/O manager.
-
-The badblocks_list functions now store the bad blocks in a sorted
-order, and use a binary search to speed up badblocks_list_test.
-
-The inode scan function ext2fs_get_next_inode() may now return a soft
-error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
-those cases where part of an inode table is missing or there is a bad
-block in the inode table.
-
-Added a new function (ext2fs_block_iterate2) which adds new arguments to
-the callback function to return a pointer (block and offset) to the
-reference of the block.
-
-Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
-application to jump to a particular block group while doing an inode
-scan.
-
-The badblocks list functions were renamed from badblocks_* to
-ext2fs_badblocks_*. Backwards compatibility functions are available
-for now, but programs should be modified to use the new interface.
-
-Some of the library functions were reorganized into separate files to
-reduce the size of some programs which statically link against the
-ext2 library.
-
-Put in some miscellaneous fixes for the Alpha platform.
-
-
-E2fsprogs 1.06 (October 7, 1996)
-================================
-
-Fixed serious bug in e2fsck: if the block descriptors are bad, don't
-smash the backup copies in ext2fs_close(). (The problem was that when
-e2fsck -p discovered the problem, while it was closing the filesystem
-and exiting, it was also blowing away the backup superblocks on the
-disk, which was less than friendly.) We now make it the case that we
-only write out the backup superblock and the back block descriptors if
-the filesystem is completely free from problems.
-
-Fixed a bug in block_interate in the lib/ext2fs library which caused
-e2fsck to fail on GNU Hurd-created filesystems.
-
-Add support for Linux/FT's bootloader, which actually uses
-EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
-to clear the inode.
-
-Add support for the "A" (no atime update) attribute. (Note: this
-attribute is not yet in production kernels.)
-
-The test suite is not automatically run when doing a "make all" from
-the top level directory. Users should manually run "make check" if
-they wish to run the test suite.
-
-Upon a preenhalt(), make the printed message more explicit that
-running e2fsck "MANAULLY" means without the -p or -a options.
-
-In e2fsck, if a disconnected inode is zero-length, offer to clear it
-instead of offering to connect it to lost+found.
-
-In e2fsck, if a filesystem was just unmounted uncleanly, and needs
-e2fsck to be run over it, change e2fsck to explicitly display this
-fact.
-
-For dumpe2fs and e2fsck, cause the -V option to print out which
-version of the ext2fs library is actually getting used. (This will
-help detect mismatches of using a 1.06 utility with a 1.05 library,
-etc.)
-
-Programmers' notes:
--------------------
-
-EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
-the naming convention.
-
-In ext2fs_initialize(), make sure the description for the inode bitmap
-is correctly initialize.
-
-Fixed minor type typo in ext2fs_allocate_generic_bitmap();
-
-E2fsprogs 1.05 (September 7, 1996)
-==================================
-
-Add support for new fields in the ext2 superblock --- volume name,
-volume UUID, and last mounted field. Dumpe2fs displays these fields,
-tune2fs and mke2fs allows you to set them. E2fsck will automatically
-generate a UUID for those volumes that don't have them.
-
-Put in support for e2fsck to recognize HURD specific ext2 features ---
-most notably, the translator block. The e2fsprogs tools will now use
-the creator_os field in the superblock to correctly handle different
-OS-specific variants of the ext2 filesystem.
-
-E2fsck now fixes inodes which have a the deletion time set, but which
-have a non-zero i_link_count field by offering to clear the deletion
-time. Previously e2fsck assumed that the inode was deleted (per 0.3c
-ext2 kernel behavior) and offered to unlink the file.
-
-If e2fsck sets the clean bit, but nothing else, set the exit code
-FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
-set the filesystem valid bit when it was previously cleared. :-) This
-was needed to make the HURD fsck driver happy.
-
-If the user refuses to attach an unattached inode, e2fsck will no
-longer set the inode's link count. Otherwise, the inode would end up
-getting marked as unused, which might cause loss of data later.
-
-Make the message issued by e2fsck when the superblock is corrupt less
-confusing for users. It now mentions that another reason for the
-"corrupt superblock" message might be that the partition might not be
-an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
-
-Make the libext2 library more robuest so that e2fsck won't coredump on
-an illegal superblock where the blocksize is zero. (f_crashdisk is
-the test case).
-
-By default, create filesystems where the default checkinterval is 6
-months (180 days). Linux servers can be robust enough that 20 reboots
-can be a long, long time.
-
-Added configure flag --enable-old-bitops, which forces the bitops to
-use the old (native) bitmask operations. By default on the sparc
-platform, the standard ext2 bit ordering is now used.
-
-Added a new feature to e2fsck to byte-swap filesystems; this can be
-used to convert old m68k filesystems to use the standard byte-order
-storage for the superblock, inodes, and directory blocks. This
-function is invoked by using the '-s' option to e2fsck.
-
-Debugfs's "dump" command has been enhanced so that it writes out the
-exact size of the file so that the nulls at the end of the file are
-eliminated. The command also accept a new "-p" option which will
-attempt preserve to preserve the ownernship, permissions, and
-file modification/access times.
-
-Debugfs has two new options, -f and -R. The -R option allows the user
-to execute a single debugfs command from the command line. The -f
-option allows the user to specify a "command file" containing debugfs
-commands which will get executed.
-
-Dumpe2fs now pretty prints the check interval, instead of just
-printing the check interval as a number of seconds.
-
-Fix bugs in debugfs: the params command when no filesystem is opened
-no longer causes a core dump. It is now possible to unlink a file
-when a pathame containing a '/' is specified.
-
-Tune2fs has a new -C option which sets the number of times the
-filesystem has been mounted.
-
-Fix the chattr '-v' option so that it actually works. Chattr was
-being buggy about the -v option parsing.
-
-Programmers' notes:
--------------------
-
-The directory lib/uuid contains a set of library routines to generate
-DCE compatible UUIDs.
-
-Extended ext2fs_namei() to handle symbolic links. Added new function
-ext2fs_nami_follow() which will follow last symbolic link in the case
-where the pathname points to a sym link.
-
-The ext2fs_block_iterate function will now return the HURD translator
-block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
-iterator to return data blocks only. The ext2fs.h file now defines
-constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
-BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
-count field of the iterator callback function.
-
-The test script driver now takes an optional second argument, which is
-the test case to be run. This allows you to run a test case without
-needing to run the entire test suite.
-
-On Linux ELF systems, install the .so files in the correct places
-(/usr/lib). The .so files must be stored in the same directory as the
-.a files.
-
-Fixed miscellaneous HURD compilation issues with header file being
-included in the right order.
-
-Fixed debugfs so that it resets optind to zero, not one, since setting
-optind to zero is more correct.
-
-
-E2fsprogs 1.04 (May 16, 1996)
-=============================
-
-First "official" (1.03 was a limited release only) to support building
-e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
-kernels).
-
-This package includes a RPM specs file, that it can be built using the
-RedHat Package Manager.
-
-E2fsck now prints a hint that if there are lots of incorrectly located
-inode bitmaps, block bitmaps, and inode table blocks, the user might
-want to try using e2fsck -b 8193 first, to see if that fares any
-better.
-
-For ext2 filesystem written with the hurd, debugfs will now print out
-the translator field when printing an inode structure.
-
-Lots of miscellaneous linking/installation cleanups:
-
- Libraries are now linked using a relative pathname, instead of
- relying on -L working correct. It doesn't, in many cases, including
- current versions of GNU ld. This guarantees that the build tree is
- linking with the right libraries, instead of the ones installed in
- /usr/lib.
-
- Header files, man pages, and the et/ss shell scripts are now
- generated using a custom substitution script, instead of relying on
- the configure script. This prevents needless recompilation of
- files; in addition, the custom substitution script is much faster.
-
- e2fsck may now be linked dynamically, by using the
- --enable-dynamic-e2fsck flag to configure. This is not recommended,
- since it increases e2fsck's dependence on other files, but some
- people need to save disk space, and other critical programs on their
- systems were being linked dynamically anyway.
-
- Programs such as fsck which didn't need to be linked against
- libext2fs (or mke2fs which didn't need to be linked against libe2p)
- only link against libraries they actually need. Otherwise, those
- programs would require the presense of libraries that otherwise
- could be removed from a rescuse diskette.
-
- The ss include files are now installed correctly so they can
- actually be used by another package.
-
- If the profiling libraries are built, they are now installed on a
- "make install-libs".
-
-
-E2fsprogs 1.03 (March 27, 1996)
-===============================
-
-Change the m68k bit numbering for bitmasks to match the bit numbering
-used by all other ext2 implementations. (This change was requested by
-the m68k kernel development team.)
-
-Support (in-development) filesystem format revision which supports
-(among other things) dynamically sized inodes.
-
-Fixed a bug in the ext2 library so that an intelligent error is
-returned if mke2fs is run with a ridiculously small number of blocks
-for a partition.
-
-Fixed a bug in the ext2 library which required that the device be
-openable in read/write mode in order to determine its size. This
-caused e2fsck -n to require read/write access when it was not
-previously necessary.
-
-Fixed a bug in e2fsck which casued it to occasionally fail the test
-suite depending on which version of the floating point library it was
-using.
-
-Fixed a bug in e2fsck so that it now halts with a fatal error when
-certain superblock consistency checks fail. Previously it continued
-running e2fsck, with some potential confusing/damaging consequences.
-
-Added new flag to fsck which allows the root to be checked in parallel
-with other filesytems. This is not the safest thing in the world to
-do, but some system administrators really wanted it.
-
-Fixed -Wall flames in lib/ss.
-
-
-E2fsprogs 1.02 (January 16, 1996)
-=================================
-
-Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
-
-Change e2fsck to print statistics of how many non-contiguous files are
-on the system. Note that a file which is larger than 8k blocks, it is
-guaranteed to be non-contiguous.
-
-In mke2fs, print a warning message if a user tries to format a whole
-disk (/dev/hda versus /dev/hda1). If a user really wants to format a
-whole disk, the -F (force) option forces mke2fs to format a whole disk
-as a filesytem.
-
-Fix a bug in fsck where in some cases it might start checking
-partitions in the next pass before it finishes checking partitions in
-the current pass. This still won't cause two partitions on the same
-disk will be checked, so it's rarely a problem in real life.
-
-Patch lsattr so that it won't hang when checking a named pipe.
-
-Minor compilation fixes:
- * Fix the order of libraries that were linked in debugfs.
- * Allow the sources to be compiled with -ansi turned on.
