-E2fsprogs 1.41-WIP-0707 (July 7, 2008) git ID: c03d9924
-=======================================================
+E2fsprogs 1.41.7 (June 29, 2009)
+================================
+
+Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
+uninitalized data into the portion of the inode beyond the first 128
+bytes when operating on inodes mapped via extents; potentially
+corrupting filesystems.
+
+Fix memory leaks in e2fsprogs, including a very large memory leak
+which can cause e2fsck to run out of memory when checking very large
+filesystems using extents.
+
+The logsave program will now filter out the ^A and ^B characters when
+writing to the console.
+
+Harden ext2fs_validate_entry() so that lsdel will not read beyond the
+end of the block even if the directory block is corrupted.
+
+Fix debugfs from core dumping if the logdump command fails to open the
+output file.
+
+Enhance badblocks to print the currently tested block number when
+interrupted with ^C.
+
+Fix lsattr to exit with a non-zero status when it encounters errors.
+(Addresses RedHat Bugzilla #489841)
+
+Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
+filesystems as the kernel when encoding rec_len >= 64k. For 64k
+filesystems (currently all that is supported by e2fsprogs, this is
+only a minor corner case).
+
+Resize2fs will now update the journal backup fileds in the sup0erblock
+if the journal is moved; this avoids an unnecessary full fsck after
+resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
+
+Fix libext2fs to properly initialize i_extra_size when creating the
+journal and resize inodes.
+
+Change badblocks to allow block sizes larger than 4k.
+
+Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
+
+Update Chinese and Czech translation from the Translation Project.
+
+Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
+
+
+Programmer's Notes
+------------------
+
+Add --disable-libuuid option to configure which uses an in-system
+installed version of libuuid; the private version is enabled by
+default.
+
+Add --valgrind-leakcheck option to the test_script program which runs
+valgrind with the appropriate options to find memory leaks.
+
+
+E2fsprogs 1.41.6 (May 30, 2009)
+===============================
+
+Fix a critical regression in e2fsck introduced version 1.41.5 which
+can undo updates to the block group descriptors after a journal replay.
+
+If e2fsck receives an I/O error while replaying the journal, prompt
+the user whether they want to ignore the error or not; if e2fsck is
+run in preen mode, force fsck to abort the preen pass.
+
+Fix a bug which would cause e2fsck to core dump if the filesystem
+contains a corrupt extent header, and the user declines to clear the
+inode. (Addresses Sourceforge Bug: #2791794)
+
+Fix e2fsck to restart only once in the case of multiple block groups
+which inodes in use that are in the uninitialized part of the block
+group's inode table.
+
+To reduce user confusion, if the /etc/mtab file is missing
+ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
+new, explicit error code to indicate this case. This will cause
+e2fsck to give a clearer error message when the user is using buggy
+rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
+Bug: #527859)
+
+Fix e2fsck so that if the primary group descriptors are corrupted, but
+the backup superblock is entirely invalid, to go back to using (and
+fixing) the priary group descriptors instead of completely giving up
+on the filesystem. (Addresses Debian Bug: #516820)
+
+Change e2fsck to not abort a preen pass if an inode is found to have
+i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
+kernels (post 2.6.29) will ignore this field. So let's fix it
+automatically during the preen pass instead of forcing the user to fix
+this up manually. (Addresses Debian Bug: #526524)
+
+Add resource tracking for e2fsck passes 1b through 1d.
+
+Speed up e2fsck by eliminating unnecessary journal checks if the
+filesystem is already mounted and doesn't need recovery (since the
+kernel would have run the journal when the filesystem was mounted.)
+Also speed up e2fsck by avoiding unnecessary block group descriptor
+updates in ext2fs_close().
+
+Add support to chattr to migrate inodes from using direct/indirect
+blocks to extents.
+
+Avoid corrupting the filesystem if there is an attempt to shrink a
+filesystem using resize2fs smaller than posible by making
+ext2fs_set_bmap() more careful not to delete the old block until the
+new block can be inserted. In addition, fix a bug in how the minimum
+size of the filesystem (plus a safety margin) is calculated, and
+modify resize2fs to refuse to shrink the filesystem below that minimum
+size without the force flag.
+
+Teach blkid to try to figure out DM device names using take advantage
+of information in sysfs when running on kernels (2.6.29 and later)
+which provide this information in /sys/block/dm-<N>/dm/name; this is
+much faster than scanning for the devncie number in /dev/mapper.
+
+Fix blkid to prefer /dev/mapper/<name> device names instad of the
+private /dev/dm-X names.
+
+Add an -a option to debugfs's close_filesys command which writes any
+changes to the superblock or block group descriptors to all of the
+backup superblock locations.
+
+Add support to the filefrag program to use the FIEMAP ioctl.
+
+Update Chinese translation from the Translation Project.
+
+Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
+Launchpad Bug: #381854)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug #506064)
+
+
+Programmer's Notes
+------------------
+
+Add test code to make sure e2fsck's problem.c doesn't have two problem
+codes assigned to duplicate values.
+
+Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
+(Addresses Sourceforge Bug: #2780205)
+
+Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
+function declaration for init_resource_track() and
+print_resource_track() when RESOURCE_TRACK is not defined.
+
+The test code which is used to build the tst_csum progam has been
+moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
+avoid compile problems caused by not having a prototype for
+ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
+
+Update the config.guess and config.sub file to the latest from the
+FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
+Debian Bug: #528330)
+
+Add a new function, ext2fs_extent_open2(), which behaves like
+pext2fs_extent_open(), but uses the user-supplied inode structure
+when opening an extent instead of reading the inode from disk.
+
+
+E2fsprogs 1.41.5 (April 23, 2009)
+=================================
+
+Fix a number of filesystem corruption bugs in resize2fs when growing
+or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
+is not mounted).
+
+Debugfs can now set i_file_acl_high via the set_inodes_field command,
+and print a 64-bit file acl. This is useful for debugging filesystem
+corruptions where the high bits of i_file_acl_high are set. E2fsck
+will detect and fix non-zero i_file_acl_high on 32-bit filesystems
+since some Linux kernel versions pay attention to this field even when
+they shouldn't.
+
+Speed up e2fsck when checking clean filesystems by avoiding
+unnecessary block reads, and coalescing the block group descriptor
+blocks so they are read using a single read operation.
+
+The libuuid library will now close all file descriptors before running
+uuidd. This avoids problems when the calling program has open sockets
+which then never get closed because uuidd is a long-running helper
+daeomn. (Addresses Launchpad bug: #305057)
+
+In order to avoid unnecessary full filesystem checks by e2fsck after
+an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
+the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
+
+Mke2fs will avoid trying to create the journal when run in
+superblock-only mode (mke2fs -S), since the left-over journal in the
+inode table will cause mke2fs to fail.
+
+Fix a bug in libext2fs functions that check to see if a particular
+device or filesystem image is mounted, which would cause these
+functions to report that a file identical to the (relative) pathname
+used by a pseudo-filesystem was mounted when in fact it was not.
+
+Update Czech translation from the Translation Project.
+
+Add Chinese (simplified) translation from the Translation Project.
+
+Fix support for external journals (which was broken in e2fsprogs
+1.41.4).
+
+Fix a regression in debugfs where the "stat" command when no
+filesystem was open would cause debugfs to crash with a segmentation
+violation.
+
+Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
+used to support filesystems without a journal. Update the blkid
+library so it understands this.
+
+The blkid library will remove an entry from the blkid cache
+representing the entire disk if partitions are found, since presuambly
+the device previously had no partition table, but has now transitioned
+to using a partition table.
+
+Add a check to mke2fs and tune2fs that the argument to the -m option
+(which specifies the reserved ratio) must be greater than zero.
+(Addresses Debian Bug: #517015)
+
+Add support for tracking the number kilobytes written to the
+filesystem via the superblock field s_kbytes_written. It will be
+updated by the kernel as well as by e2fsprogs programs which write to
+the filesystem. This is useful for tracking the wear to filesystems
+on Solid Sstate Drives.
+
+Fix compatibility issue in the libext2fs info file and makeinfo
+version 4.12. (Addresses Red Hat Bugzilla: #481620)
+
+Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug: #506279)
+
+Programmer's Notes
+------------------
+
+Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
+Bug: #521602)
+
+Fix various gcc compilation warnings and other programming cleanups.
+(Addresses Red Hat Bugzilla: #486997)
+
+Add support for building the blkid command statically.
+
+Add support for disabling the built-in blkid library in favor of a
+system-installed blkid implementation via the configure option
+--disable-libblkid.
+
+
+E2fsprogs 1.41.4 (January 27, 2009)
+===================================
+
+Fixed a bug which could sometimes cause blkid to return an exit value
+of zero for a non-existent device (Addresses Debian Bug: #502541)
+
+Blkid will now recognize ext3 filesystems that have the test_fs flag
+set as ext3 filesystems.
+
+The blkid library will now recognize btrfs filesystems and swap
+devices currently used by user-level software suspend.
+
+Tune2fs now updates the block group checksums when changing the UUID
+to avoid causing e2fsck to complain vociferously at the next reboot.
+
+Tune2fs's inode size resizing algorithms have been fixed so it is not
+vastly inefficient for moderate-to-large filesystems, due to some
+O(n**2) and O(n*m) algorithms that didn't scale well at all.
+
+Fix tune2fs's inode resizing algorithm so it will not corrupt
+filesystems laid out for RAID filesystems; in addition, tune2fs will
+refuse to change the inode size for filesystems that have the flex_bg
+feature enabled. (This is a limitation in the current implementation
+of tune2fs -I.)
+
+E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
+filesystems with 32-bit block numbers, when the headers for 64-bit
+block numbers was added. This regression has been fixed.
+
+Debugfs's ncheck command has been fixed to avoid printing garbage
+characters at the end of file names.
+
+Fix resize2fs for ext4 filesystems. Some blocks that that need moving
+when shrinking filesystems with uninit_bg feature would not be moved.
+In addition, blocks and inode table blocks were not being correctly
+freed when shrinking filesystems with the flex_bg feable, which caused
+resize2fs -M to fail. Finally, when blocks are moved, make sure the
+uninitialized flag in extents is preserved.
+
+Fix bug which caused dumpe2fs to abort with an error if run on a
+filesystem that contained an external journal.
+
+Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
+for this in argv[0] to provide better legacy support for these
+distributions. This is a practice that should NOT be continued,
+however.
+
+Mke2fs now has a new option -U, which allows the user to specify the
+UUID that should be used for the new filesystem.
+
+Mke2fs will treat devices that are exactly 16TB as if they were 16TB
+minus one block. This allows users who have read that ext3 supports
+up to 16TB filesystems and who create a 16TB LVM to not get confused,
+since the true limit is really 16TB minus one block.
+
+E2fsck will no longer abort an fsck run if block group has an errant
+INODE_UNINIT flag.
+
+E2fsck now distinguishes between fragmented directories and fragmented
+files in verbose mode statistics and in the fragcheck report.
+
+Fix a bug in e2fsck which casued it double count non-contiguous
+extent-based inodes.
+
+E2fsck will leave some slack space when repacking directories to allow
+room for a few directory entries to be added without causing leaf
+nodes to be split right away.
+
+Fix a bug which caused e2fsck to crash when it comes across a
+corrupted interior node in an extent tree with the error message:
+"Error1: Corrupt extent header on inode XXXXXX"
+
+E2fsck problem descriptions involving the journal are no longer
+referred to as "ext3" problems, since ext4 filesystems also have
+journals.
+
+Fix a long-standing bug in e2fsck which would cause it to crash when
+replying journals for filesystems with block sizes greater than 8k.
+
+Update Catalan translation from the Translation Project.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #503057, #502323, #511207)
+
+Programmer's Notes
+------------------
+
+Fix build of e2fsck.profiled, and add support for building profiled
+binaries in the misc directory if configured with --enable-profile.
+
+The ext2fs_open() function now performs more sanity checks on the
+superblock to avoid potential divide by zero errors by other parts of
+library.
+
+The ext2fs_read_inode_full() function now has a safety check to avoid
+a segmentation fault on corrupted filesystems.
+
+The ext2fs_new_inode() function now has a sanity check so that if the
+s_first_inode field in the superblock is insane, it will return
+EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
+
+To avoid segmentation faults, ext2fs_block_alloc_stats() and
+ext2fs_inode_alloc_stats() now validates the passed inode or block
+number to avoid overrunning an array boundary.
+
+Various signed/unsigned errors for variables containing block numbers
+have been fixed.
+
+Accomodations for gcc's stupidity in not realizing that constant
+strings that do not contain a '%' character are safe to use in format
+strings have been made so that distributions that want to compile
+e2fsprogs with -Werror=format-security have an easier time doing so.
+
+Added a new 64-bit getsize interface, ext2fs_get_device_size2().
+
+Added the utility make-sparse.c to the contrib directory.
+
+The ext2fs_block_iterate2() function now reflects errors from
+ext2fs_extent_set_bmap() to the caller, if the callback tries to
+change a block on an extent-based file, and ext2fs_extent_set_bmap()
+fails for some reason (for example, there isn't enough disk space to
+split a node and expand the extent tree.
+
+The ext2fs_block_iterate2() function will preserve the uninit flag in
+extents when the callback function modifies a block in an extent-based
+file.
+
+E2fsck will now flag filesystems that have an insane s_first_ino field
+in their superblock, and attempt to use a backup superblock to repair
+the filesystem.
+
+
+E2fsprogs 1.41.3 (October 12, 2008)
+===================================
+
+E2fsck has been fixed so it prints the correct inode number for
+uinit_bg related problems.
+
+E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
+is available on linux. This can be disabled via a configuration
+option in /etc/e2fsck.conf.
+
+Fix a file descriptor leak in libblkid when checking to see if an ext4
+or ext4dev module exists.
+
+Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
+while trying to close a filesystem can lead to infinite loops.
+(Addresses Red Hat Bugzilla #465679)
+
+Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
+will cause resize2fs to drop into an infinite loop. (Addresses Red
+Hat Bugzilla: #465984)
+
+Add a check in the Unix I/O functions in libext2fs so that when a
+device is opened read/write, return an error if the device is
+read-only using the BLKROGET ioctl.
+
+Fix debugfs's ncheck command so that it prints all of the names of
+hardlinks in the same directory.
+
+Fix a bug in libblkid so it correctly detects whether the ext4 and
+ext4dev filesystems are available, so that the ext4dev->ext4
+fallback code works correctly.
+
+Programmer's Notes
+------------------
+
+Fix a parallel build problem by making sure util/subst is built before
+trying to build the lib/et directory. (Addresses Sourceforge Bug:
+#2143281)
+
+Updated "make depend" information for crc16.o
+
+
+E2fsprogs 1.41.2 (October 2, 2008)
+==================================
+
+Fix e2fsck's automatic blocksize detection. This fixes a regression
+from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
+specifies a block number using the -b option if the blocksize option
+isn't also specified using -B. Unfortunately, users very commonly
+invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
+superblock; in fack e2fsck will often suggest this kind of command
+line. Oops.
+
+Enhance the debugfs's "ncheck" command so it will print all of the
+pathnames for the specified inodes. (Previously, in some cases ncheck
+might not print a pathname for an inode at all if some of the other
+inodes had multiple hard links.)
+
+Enhance debugfs's "hash" command so the hash seed can be specified via
+a command-line option. In addition, allow the hash algorithm to be
+specified by name instead of just by number.
+
+Fix e2fsck so that we don't accidentally print the translation file's
+header when asking the user a custom question so there is no prompt
+defined for a particular problem record. For example, the question
+"Run journal anyway" will get the PO header tacked on because e2fsck
+erroneously passed the null string to _(). (Addresses Launchpad Bug:
+#246892)
+
+Enhance badblocks so that it can test a normal file which is greater
+than 2GB.
+
+Enhance the badblocks command so that it displays the time and
+percentage complete when in verbose mode. (Addresses Debian Bug:
+#429739)
+
+Fix a potential memory leak in a error handling path in debugfs's
+ncheck function.
+
+Fix a potential memory corruption problem if a memory allocation fails
+in resize2fs.
+
+Fix the usage message for debugfs's logdump command to be consistent
+with its man manpage.
+
+Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
+and Sweedish translation from the Translation Project.
+
+Add documentation for the file I/O functions to the libext2fs.texinfo
+file. (Addresses Debian Bug: #484877)
+
+Update and clarified various man pages. (Addresses Launchpad Bug
+#275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug: #497619)
+
+Programmer's Notes
+------------------
+
+Fix a potential file descriptor leack in libcom_err by setting the
+close-on-exec flag for a fd used for debugging. (Addresses Red Hat
+Bugzilla #464689)
+
+Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
+has been carrying a patch for a long time to prevent a largely
+theoretical race condition if a multi-threaded application adds and
+removes error tables in multiple threads. Unfortunately SuSE's
+approach breaks compatibility by forcing applications to link and
+compile with the -pthread option; using pthread mutexes has
+historically been problematic. We fix this by using sem_post/sem_init
+instead.
+
+Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
+Sourceforge Bug: #2087502)
+
+Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
+libraries when using ELF shared libraries.
+
+Fix ELF shared library when building on systems that don't already
+have the e2fsprogs shared libraries already installed. (Addresses
+Sourceforge Bug: #2088537)
+
+Fix the pkg-config files so they work correctly when linking with
+static libraries and fix the include directory so programs don't have
+to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
+instead. (Addresses Sourceforge Bug: #2089537)
+
+Make sure ext2fs_swab64() is compiled for all platforms, and not just
+for x86. (Addresses Debian Bug: #497515)
+
+Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
+non-x86 platforms. (They had been removed for x86 earlier.)
+
+Fix diet libc compilation support, which had bitrotted due to lack of
+TLC. Fixing this improves general portability.
+
+When installing the link library when using ELF shared libraries,
+avoid using absolute pathnames if the link library and the shared
+library are installed in the same directory. (Addresses Sourceforge
+Bug: #1782913)
+
+Fix gen-tarball so it will work even if the top-level directory has
+been renamed to something other than "e2fsprogs". Also make
+gen-tarball print the size of the resulting tar.gz file.
+
+
+E2fsprogs 1.41.1 (September 1, 2008)
+====================================
+
+Many people are forgetting to update their mke2fs.conf file, and this
+causes ext3, ext4, and ext4dev filesystems won't get created with the
+proper features enabled. We address this in two ways. First, mke2fs
+will issue a warning if there is not definition for an ext3, ext4, or
+ext4dev filesystem and the user is trying to create such a filesystem
+type. Secondly, when installing from a source build, "make install"
+will provide basic configuration file handling for /etc/mke2fs.conf.
+If it exists, and does not mention ext4dev, it will be moved aside to
+/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
+be installed. If the existing /etc/mke2fs.conf file does mention
+ext4dev, then "make install" will install official mke2fs.conf file as
+/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
+they should look to see if any changes need to be merged.
+
+The mke2fs program will now create the journal in the middle of the
+filesystem, since this minimizes seek times on average for fsync-heavy
+workloads. In addition, mke2fs will now create journals using extents
+for filesystems that support them. This results in a more efficient
+encoding for the journal since it eliminates the need for using
+indirect blocks.
+
+The mke2fs program will avoid allocating an extra block to the
+journal. (Addresses Sourceforge Bug: #1483791)
+
+Mke2fs will correctly enforce the prohibition against features
+(specifically read-only features) in revision 0 filesystems. (Thanks
+to Benno Schulenberg for noticing this problem.)
+
+Mke2fs previously would occasionaly create some slightly non-optimally
+placed inode tables; this bug has been fixed.
+
+The mke2fs and tune2fs programs now print the correct usage message
+describing the maximum journal size. (Addresses Debian Bug: #491620)
+
+Add support for setting the default hash algorithm used in b-tree
+directories in tune2fs (from a command-line option) or mke2fs (via
+mke2fs.conf). In addition, change the default hash algorithm to
+half_md4, since it is faster and better.
+
+The blkid library will now recognize MacOS hfsx filesystems, and
+correctly extract the label and uuid for hfs, hfsx, and hfsplus
+filesystems. (Addresses Sourceforge Feature Requests: #2060292)
+
+The blkid library has improved detection of JFS and HPFS filesystems.
+(Addresses Launchpad Bug: #255255)
+
+The blkid library is now much more efficiently handling devicemapper
+devices, mainly by no longer using the devicemapper library. This can
+speed up access for systems with a large number of device mapper
+devices.
+
+Blkid had a number of cache validation bugs in libblkid that have been
+fixed. (Addresses Debian Bug: #493216)
+
+Resize2fs will now properly close out the "updating inode references"
+progress bar so there is a newline printed before printing the final
+"resize is successful" message.
+
+Resize2fs will now correctly handle filesystems with extents and/o
+uninitialized block groups correctly when file/directory blocks need
+to relocated (i.e., when shrinking a filesystem or if the resize_inode
+is not present). To support this, the ext2fs library now supports
+initializing inode and block bitmaps that are not yet initialized when
+allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
+addition, e2fs_block_iterate2() can now support changing the location
+of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
+been optimized to avoid creating unnecessary new extents when updating
+the location of blocks in the extent tree. This will also help out
+e2fsck's recovery of obscurely corrupted filesystems with extents,
+when blocks are claimed by multiple inodes.
+
+Add support for on-line resizing ext4 filesystem with the flex_bg
+filesystem feature. The method for doing so is not optimal, but to do
+a better job will require kernel support.
+
+E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
+debugfs programs to not be able to read e2image files; the signed
+vs. unsigned bug in the code which read bitmaps from the e2image has
+been fixed. (Addresses Debian Bug: #495830)
+
+Resize2fs is now correctly managing the directory in-use counts when
+shrinking filesystems and directory inodes needed to be moved from one
+block group to another. This bug has been around since e2fsprogs
+1.26, and is largely harmless, but does cause a filesystem corruption
+which will be flagged by e2fsck after the filesystem has been shrunk.
+
+E2fsck will no longer issue spurious complaints about the inode size
+caused by very large extent-based files, and by blocks reallocated
+using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
+Kernel Bugzilla: #11341)
+
+Mke2fs will now set the creation timestamp on the lost+found directory
+and the root directory. (More generally, all new inodes created using
+the ext2fs library will correctly set the creation timestamp.)
+
+E2fsck now correctly calculates ind/dind/tind statistics in the
+presence of extent-based files. In addition, "e2fsck -v" will report
+statistics of the depth of extent trees in the filesystem. E2fsck can
+also give an inode fragmentation report using "e2fsck -E fragcheck"
+which can be useful when debugging the kernel block allocation
+routines.
+
+Fix support for empty directory blocks in ext4 filesystems with 64k
+blocksize filesystems.
+
+E2fsck will now print the depth of corrupt htree directories.
+
+Debugfs's htree command now correctly understands extent-based
+directories. It will also print out the minor hash as well as the
+major hash.
+
+Debugfs has a new command which will print the supported features of
+e2fsprogs, to enable scripts to know whether the installed version of
+e2fsprogs can support a specific feature.
+
+Debugfs will now write files using extents for filesystems that
+support them.
+
+The error message printed by "tune2fs -I" if the inode size was too
+small was rather confusing, so it has been improved. Also, we won't
+try to create an undo log until we know that command-line-specified
+parameters such as "tune2fs -I <inode size>" are valid.
+
+Given some filesystems found "in the wild" that had non-zero block
+group checksums even though the uninit_bg/gdt_sum feature was not
+enabled, e2fsck would issue spurious error messages. Teach
+ext2fs_group_desc_csum_verify() to ignore the block group checksum
+entirely if the feature flag is not set. (Addresses Debian Bug:
+#490637)
+
+The blkid program will now print out a user-friendly listing of all of
+the block devices in the system and what they contain when given the
+-L option. (Addresses Debian Bug: #490527)
+
+The filefrag program now has a more accurate calculation for the
+number of ideal extents. (Addresses Debian Bug: #458306)
+
+The test I/O manager is now enabled by default, but its overhead is
+only incurred when it would be enabled via the TEST_IO_FLAGS or
+TEST_IO_BLOCK environment variables.
+
+Typographical errors in various program strings and usage messages
+have been fixed; most of these were pointed out by the e2fsprogs
+message catalog translators. (Thanks, translators!)
+
+Update and clarified various man pages, as well as some typographical
+errors in the libext2fs texinfo file.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details.
+
+Add Indonesian and update French, Polish, Dutch, German, Sweedish,
+Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
+#401092)
+
+Programmer's Notes
+------------------
+
+Fix portability problem with the badblocks group; for systems that
+don't have nanosleep(), try using usleep() instead.
+
+The "make check" target in the e2fsck directory now sets
+LD_LIBRARY_PATH before running the various e2fsck internal library
+regression tests.
+
+The crc32 regression test in the e2fsck library is now portable to
+greater varienty of environments, including big-endian systems and
+when cross-building e2fsprogs for embedded systems. (Addresses
+Sourceforge Bug: #2019287)
+
+The ext2fs_extent_set_bmap() had some bugs when setting the first
+block in a file, or when replacing a single block extent. Those cases
+fortunately were came up relatively rarely when e2fsck was checking
+files, but caused some problems when resize2fs was shrinking
+extent-based files.
+
+Fix a potential core-dumping bug in libe2p's iterate_on_dir()
+function.
+
+Various ext2fs library functions --- ext2fs_block_iterate2(),
+ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
+allocated memory to avoid memory leaks in all of their error return
+paths.
+
+Ext2ed was failing to build because masix support had been removed in
+the rest of e2fsprogs, so ext2ed no longer has masix support, either.
+
+The configure script now respects the LDFLAGS environment variable if
+it is set when configure is called. (Addresses Sourceforge Feature
+Request: #1937287)
+
+Libuuid is now more portable to the Windows platform. (Addresses
+Sourceforge Feature Request: #1937287)
+
+The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
+bare echo commands so that configure flags such as --quiet work
+correctly. (Addresses Sourceforge Patches: #2058794)
+
+A few uses of sprintf have been removed from the ext2fs library to
+make life easier for bootloaders with a limited libc environment.
+(Addresses Sourceforge Bug: #2049120)
+
+The ext2fs_read_inode() checks the validity of the inode number passed
+to it earlier, to avoid doing some needless work when it would fail
+anyway.
+
+The ext2fs_open() checks the validity of the blocksize parameter
+passed to it earlier, to avoid doing some needless work when it would
+fail anyway.
+
+Disable a very annoying automatic "%.sh -> %" GNU make rule in the
+top-level Makefile. That automatic rule is used to better support
+SCCS, but it caused problems for a particular niche distribution which
+likes to use configure.sh files to store the configure options used to
+build a package. Unfortuntaely GNU make will use the configure.sh to
+replace the configure script, resulting in a self-inflicted fork bomb
+leading to an out-of-memory crash.
+
+To support old GNU C compilers don't use C99/C++ comments, but only
+K&R style comments, and don't try to use __builtin_expect if __GNUC__
+is less than 3. (__builtin_expect is only supported for gcc versions
+2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
+this is an optimization, we only try to use __builtin_expect for gcc 3
+and up.)
+
+In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
+__LITTLE_ENDIAN, which are only defined by glibc's header files and
+hence isn't portable.
+
+For the convenience for some distributions that need a static tune2fs,
+the Makefile for misc/ now has a tune2fs.static target.
+
+The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
+for extent-based files
+
+The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
+files.
+
+All source files no longer have any trailing white space.
+
+The io_channel_read_blk64() and io_channel_write_blk64() functions are
+now functions instead of C preprocessor macros to provide better
+forward compatibility.
+
+The e2fpsrogs translation template now expands the @x abbrevation.
+
+Various namespace leackages in libblkid, libe2p, and libext2fs have
+been fixed.
+
+Fix a parallel build problem in e2fsprogs.
+
+E2fsprogs is now more portable to Solaris.
+ * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
+ are always present.
+ * Scripts do not assume that /bin/true is always in /bin
+ * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
+ * Flush stdio handles before calling setbuf(), since Solaris will
+ discard any pending output to the stream.
+ * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
+ picky about which C compiler can beused for SUSv3 conformance.
+ Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
+ and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
+ Since we need some SUSv3 functions, consistently use SUSv3 so
+ that e2fsprogs will build on Solaris using c99.
+ * Solaris C99 does not support varargs C preprocessor macros
+ * Solaris header files pollute the C namespace if in/netinet.h
+ is included, which conflicts with e2fsprogs' use of the kmem_cache_t
+ typedef.
+ * Solaris ships with a pathetically ancient shell in /bin/sh so we
+ avoid the use of various more avanced shell constructs such as $().
+
+The "make rpm" command will now take some extra configure optiosn from
+the build environment without needing to patch the source tree.
+
+The ext2fs_add_dir_block() function will now grow the dblist more
+aggressively as an optimization to avoid copying the array too often.
+
+The e2fsck_write_bitmaps() will write the block and inode bitmaps
+together instead of in two passes.
+
+
+E2fsprogs 1.41 (July 10, 2008)
+==============================
Add support for ext4 filesystem features, in particular extents,
uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
Add support for "undo" support. E2fsck and mke2fs can optionally
record an undo log which can replayed by the program e2undo.
+E2fsck could damage a filesystem by trying to relocate inode tables
+due to corrupted block group descriptors, where the attempted inode
+table relocation would do far more harm than good. E2fsck has been
+fixed to detect this these sorts of corrupted block group descriptors
+much earlier in e2fsck processing, so it can try to use the backup
+superblock and block group descriptors first. This should be a much
+better strategy for recovering these types of corrupted filesystems.
+(Addresses Sourceforge Bug: #1840291)
+
E2fsck will display a more understandable message when the last check
field in the superblock is in the future. (Addresses Debian Bug:
#446005).
+E2fsck now performs more extensive and careful checks of extended
+attributes stored in the inode.
+
Enhance mke2fs to print a more explanatory error message when
ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
#488663)
blkid_find_dev_with_tag() never returns a non-existent device. Also,
if a filesystem is found at a new /dev location, eliminate any
duplicate stale entries which can not be verified.
-(Addresses-Debian-Bugs: #487758, #487783)

Add more paranoid checks for LVM volumes and swap partitions in
blkid's probe function, to reduce the chances of false positives.
information is used to extract configuration parameters from the
/etc/mke2fs.conf file.
-Resize2fs will now print the minimum needed filesystem size if given
-the -P option, and will resize the filesystem to the smallest possible
-size if given the -M option.
-
The mke2fs program will no longer complain and request the -f option
when the user tries to create a filesystem with greater than 2**31
blocks.
-E2fsck now performs more extensive and careful checks of extended
-attributes stored in the inode.
-
+When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
+adjust the mke2fs.conf file so filesystems for the Hurd are created
+with a blocksize of 4096 and inode size of 128, which is all it knows
+how to handle. (Addresses Debian Bug: #471977)
+
Mke2fs will always make sure that lost+found always has at least 2
blocks, even for filesystems with very large blocksizes (i.e., 64kb).
+Resize2fs will now print the minimum needed filesystem size if given
+the -P option, and will resize the filesystem to the smallest possible
+size if given the -M option.
+
+Fix resize2fs to clean up the resize_inode if all of the reserved gdt
+blocks are consumed during an off-line resize.
+
The "ls" command in debugfs now supports the -p option, which causes
it to quote the filenames so that spaces or tabs in directory entries
are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
Czech translations.

Programmer's Notes
------------------
Avoid using predictable filenames in /tmp in blkid's regression test
suite. Also remove bashism's in the regression test script.
+If the configure script is given --with-diet-libc, don't use thread
+local storage, since diet libc doesn't support TLS. (Addresses
+Sourceforge Bug: #2000654)
+
+Fix the blkid regression test suite to tolerate older versions of
+mkswap that don't support the -U option.
+
A few library routines have been converted to support 64-bit block
numbers; in particular, the I/O manager functions, the test_io,
inode_io, and unix_io managers have all be converted to support 64-bit
