+E2fsprogs 1.26-WIP (December 24, 2001)
+======================================
+
+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 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)
+
+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.
+
+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.
+
+
+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)
=============================
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 use
-their own private copy of ext2_fs.h if they aren't already.
+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
