-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.
