-E2fsprogs 1.40.9-WIP (March 14, 2008)
+E2fsprogs 1.42.9 (December 28, 2013)
+====================================
+
+Mke2fs will detect an attempt to create a file system on a loop
+mounted file and complain without the -FF option. Also fixed mke2fs
+so it allows the creation of a file system on a mounted device with
+two -F options, as documented in the man page, instead of three -F
+options.
+
+Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
+libext2fs to correctly handle bigalloc and 64-bit file systems. There
+were many corner cases that had not been noticed in previous uses of
+these file systems, since they are not as common. Some of the bugs
+could cause file system corruption or data loss, so users of 64-bit or
+bigalloc file systems are strongly urged to upgrade to e2fsprogs
+1.42.9.
+
+The tune2fs program will now not allow changing the uuid on a mounted
+file system which has the uninit_bg feature enabled. This avoids a
+nasty race where the kernel and tune2fs are both retrying rewrite the
+group descriptors at the same time, with different ideas about what
+the UUID should be.
+
+When e2fsck is rehashing an extent-mapped directory, it's possible
+(although very rare) that an extent block will need to be allocated;
+fix e2fsck to make sure that the block gets marked as used.
+
+Mke2fs will now properly set the LARGE_FILE feature when creating a
+journal >= 2GB --- which can happen when using 64k block size.
+
+Fixed debugfs so that its freei command will correctly handle a request
+to free a range of consecutive inodes.
+
+Fixed 2fsck so it will not erroneously complain that an external journal
+is invalid if it is exactly 2**32 blocks.
+
+Fixed e2fsck so it won't try checking for, and adding, a missing
+lost+found directory when running in read-only mode.
+
+Fixed e2image to avoid some buffer overruns which would cause it to when
+creating a "standard (non-raw, non-qcow2) image file. Standard
+e2image files are actually very rarely used, so we didn't notice when
+the changes to enable the qcow2 format broke this e2image mode.
+
+Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
+on the resize_inode feature when the meta_bg feature is set, since
+these two features can not be set at the same time.
+
+Fixed tune2fs so that when it disables the quota feature, it updates all
+of the backup superblocks.
+
+Fixed dumpe2fs that would cause it to abort when run using an image file
+when trying to print the journal information (which is not present in
+an e2image created image file).
+
+Fixed a potential integer overflow in e2reefrag.
+(Addresses-Debian-Bug: #718205)
+
+Enhance debugfs so that when copying a sparse file from a native file
+system into the file system image using the "write" command, it will
+create a sparse file into the destination file system.
+
+Enhanced debugfs so it can support a command line which is up to 8k
+long.
+
+E2image will refuse (unless the -f option is specified to force the
+issue) to create a raw or qcow image using a mounted file system,
+unless the -f option is specified to force the issue.
+
+E2image has been optimized for using it to efficiently copy a file
+system by only copying the allocated blocks, by using the options -ra.
+New options (-o and -O) have been added so that a source and
+destination offset can be given. The -p option will print progress
+information so the user will know how far along the copy is going.
+And finally, the new option -c is useful for updating a file system on
+an SSD, by avoiding unnecessary writes. E2image can also shift a file
+system image by doing an in place move.
+
+Fix a regression introduced in 1.42.8 which would cause e2fsck to
+erroneously report uninitialized extents past the EOF (as determined by
+i_size) to be invalid.
+
+Fixed resize2fs so under a corner case when an inode has a complex
+extent tree, it will not corrupt an interior node in the extent tree.
+
+Fixed resize2fs which would sometimes corrupt a file system when
+shrinking a file system to a minimum size using resize2fs -M.
+(Addresses Debian Bug: #660793)
+
+Fixed resize2fs so that it will relocate inode table blocks if this
+becomes necessary when shrinking the file system.
+
+Fixed resize2fs and e2fsck so they will not crash when hit a failure
+while operating on a file system with the MMP feature enabled.
+
+Fixed a bug in debugfs which caused it create an invalid inode when
+trying to write a zero-length file.
+
+E2fsck will no longer crash if it tries to delete an invalid
+extent-mapped symlink.
+
+E2fsck will no longer crash if it comes across an directory which is
+larger than 2GB (which is not allowed in valid file systems).
+
+Fixed debugfs's help texts to fully document all options and otherwise
+be more helpful.
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #586218,
+#669730, #698076)
+
+Fixed various Debian Packaging Issues (#698879, #721365)
+
+
+Programmer's Notes
+------------------
+
+Fix sparse, gcc -Wall and clang nits.
+
+Update config.{guess,sub} to the latest version
+
+Fixed various memory and file descriptor leaks on various error paths,
+as well as some missing error return checks, which were found using
+Coverity.
+
+Run sparse against source files when building e2fsprogs with 'make
+C=1'. If instead C=2, it configures basic ext2 types for bitwise
+checking with sparse, which can help find the (many many) spots where
+conversion errors are (possibly) happening.
+
+Allow the regression test to be run in chrooted environments where
+/etc/mtab might be missing.
+
+The ext2fs_punch() function, which was introduced in 1.42, was broken
+in many ways, but this was never noticed since it wasn't used for
+anything significant. Some of the bugs include failing when trying to
+punch a completely sparse file, failing when punching an extent-mapped
+inode when the starting block was at the beginning of the inode, and
+not being able to punch a single block (where start_blk == end_block).
+It also didn't handle being passed an invalid, too-large ending block
+number, and didn't handle properly terminate at the right place when
+operating on an indirect-mapped inode.
+
+Fixed some minor typo's in the error catalog for libext2fs.
+
+Fixed ext2fs_file_set_size2() so that if it truncates an inode by
+setting the file size, to zero the rest of the block to the end of the
+file, so that if an ext4 FUSE driver tries to extended the file, that
+we don't avoid stale data from being returned.
+
+Fixed ext2fs_bmap() to disallow clients from trying to map or set
+logical blocks which are larger than what an extent-mapped or indirect
+block-mapped inode can allow.
+
+If debugfs (or some userspace program using libext2fs) creates a file
+which is larger than 2GB, make sure the large_file feature flag gets
+set.
+
+Fix a bug in ext2fs_link() where if there is multiple empty slots in the
+directory which are large enough, the directory entry could get
+inserted more than once in the directory.
+
+If quota support is disabled (which is the default), make sure that
+all traces of the quota support is removed from usage messages, man
+pages, and tune2fs must not be able to enable the quota file system
+feature. (Addresses Red Hat Bugzilla: #1010709)
+
+The ext2fs_file_write() now updates i_size on a successful write,
+instead of only updating i_size wen the file is closed via
+ext2fs_file_close().
+
+Added a shell script, populate-extfs.sh which uses debugfs to populate
+an ext2/3/4 file system image from a given directory. It is similar
+to the genext2fs program, but it supports ext3 and ext4 file system.
+
+Add changes to the libext2fs library to support block group
+descriptors larger than 64 bytes (for future compatibility).
+
+Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
+leave an extra block in the file when truncating the file down to
+size.
+
+The html version info pages are now built using makeinfo --html
+instead of the unmaintained and now-obsolete texi2html program.
+
+
+E2fsprogs 1.42.8 (June 20, 2013)
+================================
+
+As a part of mke2fs's option parsing cleanup, the use of the -R option
+will give a warning that it is depreated (it has been so documented
+since 2005) and -E should be used instead.
+
+Mke2fs will not give warnings about the bigalloc and quota options in
+quiet mode.
+
+If an invalid journal size is given to mke2fs, it will now complain
+and exit sooner.
+
+Debugfs was erroneously giving spurious error messages for certain
+extent_inode subcommands which take arguments (split_node,
+replace_node, and insert_node). This has been fixed.
+
+Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
+other programs is used by mke2fs.
+
+Change mke2fs so that it does not set the root directory to the real
+uid/gid of the mke2fs process. Add the extended option root_owner to
+override this behavior.
+
+Fix resize2fs when shrinking file systems to make sure that bitmap
+blocks aren't left outside the bounds of the shrunken file system.
+This could happen with flex_bg file systems that were grown using
+the old online resizing algorithm.
+
+E2fsck will now detect and repair corrupted extent trees which contain
+invalid extents at the end of the extent tree leaf block.
+
+E2fsck will now longer complain about zero length extended attribute
+values.
+
+Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
+to crash.
+
+Add safety check so tune2fs will not attempt to set the inode size to
+be larger than the block size.
+
+Fix e2fsck so it can check a read-only root file system with an
+external journal. (Addresses Debian Bug: #707030
+
+Fix off-line resizing of file systems with flex_bg && !resize_inode
+(Addresses Debian Bug: #696746)
+
+Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug:
+#703067)
+
+Enhance chattr to allow clearing the extent flag if the kernel allows
+migrating extent based files to use indirect blocks.
+
+Update German translation.
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #712429,
+#712430, #707609)
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #708307)
+
+Programmer's Notes
+------------------
+
+Use secure_getenv() in preference to __secure_getenv().
+
+Optimize CPU utilization of ext2fs_bg_has_super().
+
+Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
+SEEK_CUR is used with large files.
+
+The ext2fs_read_inode_full() function will no longer use
+fs->read_inode() if the caller has requested more than the base 128
+byte inode structure and the inode size is greater than 128 bytes.
+
+Fix build failure with --enable-jbd-debug.
+
+Clean up filtering of outputs for the regression tests by using a
+common sed script.
+
+Fix gcc -Wall and clang nits.
+
+
+E2fsprogs 1.42.7 (January 21, 2013)
+===================================
+
+Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
+quota features are still under development. For more information
+please see:
+ * https://ext4.wiki.kernel.org/index.php/Bigalloc
+ * https://ext4.wiki.kernel.org/index.php/Quota
+
+Add some new options to filefrag from Lustre's patches to e2fsprogs:
+ * add -k option to print extents in kB-sized units (like df -k)
+ * add -b {blocksize} to print extents in blocksize units
+ * add -e option to print extent format, even when FIBMAP is used
+ * add -X option to print extents in hexadecimal format
+
+Fix resize2fs so that it can handle off-line resizes of file systems
+with the flex_bg feature but without a resize_inode (or if we run out
+of reserved gdt blocks). This also fixes a problem where if the user
+creates a filesystem with a restricted number of reserved gdt blocks,
+an off-line resize which grows the file system could potentially
+result in file system corruption.
+
+Fix a resize2fs bug which could cause it to corrupt bigalloc file
+systems when doing an off-line resize.
+
+Further optimize resize2fs so it doesn't use quite as much CPU when
+resizing very large file systems.
+
+Fixed 32-bit overflow bugs which could cause resize2fs to fail and
+possibly corrupt the file system while resizing 64-bit file systems.
+
+Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
+mke2fs crash due to a divide-by-zero if the 64bit file system feature
+is enabled.
+
+Add better error checking to mke2fs to check for invalid parameters
+when creating bigalloc file system.
+
+When creating bigalloc filesystems, the -g option to mke2fs will now
+specify the number of clusters per block group.
+
+Add to debugfs the functionality to corrupt a specific file system
+block via the "zap_block" command.
+
+Add to debugfs the functionality to print out a hex dump of a block in
+the file system via the "block_dump" command.
+
+Add to debugfs the functionality to manipulate the extent tree
+directly via the "extent_open" command.
+
+Fixed debugfs's mknod command so that it updates the block group
+statistics.
+
+Fix e2fsck so it can detect and fix inconsistencies in the interior
+nodes of an inode's extent tree.
+
+Fix a potential memory corruption failure in e2fsck's error path if
+the call to ext2fs_open2() fails.
+
+Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
+resulting file name for the log file is longer than 100 bytes, that it
+properly handles this situation instead of crashing.
+
+E2fsck will now report the amount of memory that it attempted to
+allocate when a memory allocation request fails, to make it easier to
+track down the problem.
+
+Fix mke2fs's handling of the mmp_update_interval option. (Addresses
+Lustre Bug: LU-1888)
+
+E2image can now include all data blocks in the e2image output file
+when the user specifies the -a option.
+
+If e2fsprogs is compiled without --enable-quota, make sure that
+tune2fs can not turn on the feature for new-style quota support, since
+afterwards, none of the e2fsprogs tools will be willing to touch that
+file system.
+
+Optimize e2fsck's so that it uses much less CPU for large file
+systems. This can result in significant speedups, especially on
+CPU-constrained systems. This was primarily done by optimizing
+libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
+
+Fix debugfs's htree command so that all its messages are sent through
+the pager.
+
+Fixed debugfs's "dump_file" and "cat" functions work correctly
+on file systems whose block size is greater than 8k.
+
+Fix e2freefrag so it works on 64-bit file systems, and so it uses much
+less memory. (Addresses Google Bug: 7269948)
+
+Update the spd_readdir.c file in the contrib directory to include some
+additions which were made in 2008 that didn't get folded into the
+version which we checked into the e2fsprogs source tree. These
+enhancements include thread safety, support for readdir64_r(), and
+safe_getenv() support in case spd_readdir.so is used for setuid binaries.
+
+Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
+translations
+
+Add a command to debugfs to create symlinks.
+
+Document the bigalloc feature in the mke2fs man page. (Addresses
+Debian Bug: #669730)
+
+
+Programmer's Notes
+------------------
+
+Fix gcc -Wall nits.
+
+Fix a spelling typo in the libext2fs texinfo documentation.
+
+Change the output from "make check" so that tools such as emacs's "M-x
+compile" does not mistake the output as containing a compiler error.
+
+Export two new functions from libext2fs: ext2fs_extent_node_split()
+and ext2fs_extent_goto2().
+
+The ext2fs_extents_fix_parents() was fixed so it does not modify the
+location of the extent handle if its current location is at an
+interior node, rather than a leaf node of an inode's extent tree.
+
+Add a regression test to assure that e2fsck can correctly fix an
+inconsistent interior node in an inode's extent tree.
+
+The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
+correctly support bigalloc file systems which use store block usage
+information in units of clusters.
+
+Fixed the help text in the configure script for --enable-quota.
+
+The m68k-specific bitops code has been removed since they were
+incorrectly treating bit numbers with the high bit set as signed
+integers. Furthermore, modern compilers do a good enough job
+optimizing the generic code there is no point in having the m68k
+specific asm statements.
+
+Fixed how we link the test programs so they always use the static
+libraries, so that we test using the libraries which we have just
+built.
+
+Update config.guess and config.sub to the latest versions from the GNU
+project.
+
+Fixed the com_err.texinfo file so that it can produce a valid
+postscript/pdf printed output.
+
+Add a regression test which checks debugfs's ability to create
+symlinks, named FIFO's, and device nodes.
+
+Add a function ext2fs_symlink(), which creates symlinks to the
+libext2fs library.
+
+Add debugging code so we can test old kernel interfaces for online
+resize to resize2fs. This backwards compatibility checking is keyed
+off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
+test the functionality of the kernel's older resize ioctls without
+needing to install an old version of resize2fs, and to also test a
+modern resize2fs's ability to work with older kernels without having
+to install an older version of the kernel.
+
+
+E2fsprogs 1.42.6 (September 21, 2012)
+=====================================
+
+When mke2fs creates file systems with lazy itable initialization, the
+progress updates for writing the inode table happens so quickly that
+on a serial console, the time to write the progress updates can be the
+bottleneck. So mke2fs will now only update its progress indicators
+once a second.
+
+Resize2fs will skip initializing the inode tables if the kernel
+supports lazy_itable_init, which speeds up growing off-line growth of
+uninit_bg file systems significantly. Resize2fs will now also
+correctly set the itable_unused field in the block group descriptor to
+speed up the first e2fsck after the file system is grown.
+
+Resize2fs has been fixed so that on-line resizing of meta_bg file
+systems work correctly. This is needed to grow file system which are
+larger than 16T.
+
+Resize2fs will now correctly handle resizing file systems to 16TB on
+32-bit file systems when "16TB" is specified on the command line.
+
+Fix mke2fs so that it will be careful to set the reserved blocks ratio
+larger than 50%; this can happen when creating small file systems and
+when the last block group is dropped because there are not enough
+blocks to support the metadata blocks in the last block group.
+
+Fixed spelling mistake in debugfs's help message.
+
+Fixed a potential seg fault in e2fsck when there is an I/O error while
+reading the superblock.
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
+
+Updated/fixed various man pages. (Addresses Sourceforge Bug:
+#3559210)
+
+Programmer's Notes
+------------------
+
+The configure option --enable-relative-symlink was broken so that it
+needed to be --enable-symlink-relative-symlinks. We will support both
+for at least two years, but then the worng configure option will be
+removed.
+
+Fixed a regression introduced in 1.42.5 so the link order for
+e2fsprogs' libraries will be correct for both static and shared
+linking. (Addresses Sourceforge Bug: #3554345)
+
+Add support for e2fsprogs to be compiled using clang/LLVM.
+
+Fix portability problems on non-Linux systems: avoid compile failures
+on systems that don't have malloc.h
+
+Fix f_mmp regression test suite so that debugfs gets killed if the
+test is interrupted.
+
+
+
+E2fsprogs 1.42.5 (July 29, 2012)
+================================
+
+Fixed a bug with mke2fs where if there is only 8 inodes per block
+group, the calculation of the number of uninitialized inodes in the
+first block group would go negative. This resulted in "mke2fs -N 256
+-t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
+would run out of space. (Addresses Sourceforge Bug: #3528892)
+
+Fixed a bug in how e2fsck would uniquify directory entry names.
+(AddressesSourceforge Bug: #3540545)
+
+Previously, e2fsck would only allow a mounted file system to be
+checked if it was the root file system and it was mounted read-only.
+Now it will allow any file system mounted read-only to be checked if
+the -f option is specified. This makes it easier to test how e2fsck
+handles checking file systems which are mounted without having to test
+on the root file system.
+
+Fixed a problem if e2fsck where if the root file system is mounted
+read-only, e2fsck would not clear an error indication in the journal
+superblock. Combined with a kernel bug, this would cause the e2fsck
+to check the file system after every single boot.
+
+The e4defrag program can now handle device symlinks, such as
+/dev/mapper/testvg-testlv, instead of insisting on a less
+human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
+#707209)
+
+Fixed filefrag so it will not crash with a segfault on files from a
+virtual file system such as /proc. (e.g., "filefrag
+/proc/partitions")
+
+Fixed filefrag so that it correctly reports the number of extents.
+(Addresses Red Hat Bugzilla: #840848)
+
+Fixed a file descriptor leak in logsave which could cause it to hang.
+(Addresses Debian Bug: #682592)
+
+Fixed e2fsck so that the file system is marked as containing an error
+if the user chooses not to fix the quota usage information.
+
+Fixed tune2fs so that it correctly removes the quota feature when the
+last quota inode is removed.
+
+Fix tune2fs so that after removing a quota inode, the block bitmap is
+updated; otherwise, e2fsck would complain after running 'tune2fs -O
+^quota <dev>'.
+
+Fix tune2fs so that when converting a file system from using legacy
+quota files to the new quota file system feature with hidden quota
+files, the accounting for these files is handled correctly so that
+e2fsck doesn't complain.
+
+Improved e2fsck's verbose reporting statistics, and allow the more
+verbose reporting to be enabled via /etc/e2fsck.conf.
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
+
+
+Programmer's Notes
+------------------
+
+Fixed portability problems on other operating systems (e.g., Hurd and
+FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
+
+Make sure that shared libraries link with the shared libraries built
+in the build tree, instead of the system provided libraries.
+Previously, libraries and executables were linked with the system
+libraries if present, and possibly using static archives instead of
+shared libraries. This was also problematic since if libext2fs.so is
+linked with a static libcom_err.a from system, the build system would
+attempt to link without -lpthread. (Addresses Sourceforge Bug:
+#3542572)
+
+
+E2fsprogs 1.42.4 (June 12, 2012)
+================================
+
+Fixed more 64-bit block number bugs (which could end up corrupting
+file systems!) in e2fsck, debugfs, and libext2fs.
+
+Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
+not properly propagating the journal's s_errno field to the superblock
+field; it was not checking this field if the journal had already been
+replayed, and if the journal *was* being replayed, the "error bit"
+wasn't getting flushed out to disk.
+
+Fixed a false positive complaint by e2fsck if all of the extents in
+the last extent tree block are uninitalized and located after the end
+of the file as defined by i_size.
+
+The dumpe2fs will now display the journal's s_errno field if it is
+non-zero, and it will also display the journal's 64-bit feature flag
+if present.
+
+Fix e2fsck so that it always opens the device file in exclusive mode
+when it might need to modify the file system, and never if the -n
+option is specified. (Previously, there were a few corner cases where
+it might get things wrong in either direction.)
+
+E2fsck now correctly truncates or deallocates extent-mapped inodes on
+the orphan list. The root cause was a bug in libext2fs's block
+iterator which could end up skipping an extent when the last block in
+an extent is removed, causing the current extent to be removed from
+the extent tree.
+
+E2fsck now correctly sets the global free block and inode counts when
+truncating or removing inodes on the orphan list in preen mode.
+Previously, it would leave these values would be set incorrectly,
+which is largely a cosmetic issue since the kernel no longer pays
+attention to those fields, but it can cause spurious complaints in
+subsequent e2fsck runs.
+
+Fix i_blocks accounting when the libext2fs library needs to add or
+remove an extent tree block on bigalloc file systems.
+
+The lsattr and chattr programs now support the No_COW flag for the
+benefit of btrfs.
+
+Debugfs now interprets date strings of the form @ddd as ddd seconds
+after the beginning of the epoch. This is handy when setting an inode
+number into the d_time field when debugging orphan list handling.
+
+Fix a precedence bug with built-in quota support which might result in
+e2fsck paying attention to the quota inode field even if the built-in
+quota feature flag is not set. Fortunately, in practice that
+superblock field should be zero for non-built-in quota file systems,
+so it's unlikely this bug would have caused problems.
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
+#674694)
+
+Programmer's Notes
+------------------
+
+The regression test suite can now run the integration tests in the
+tests directory in parallel, via "make -jN check".
+
+Add new test, f_zero_extent_length which tests e2fsck's handling of
+the case where all of the extents in the last extent tree block are
+uninitialized extents after i_size.
+
+Add a new test, f_jnl_errno, which checks handling of an error
+indication set in the journal superblock.
+
+Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
+of a 64-bit journal.
+
+Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
+tests e2fsck's handling of orphan inodes in preen mode, and truncation
+of extent inodes on the orphan list.

+
+E2fsprogs 1.42.3 (May 14, 2012)
+===============================
+
+Fix a bug in the Unix I/O manager which could cause corruption of file
+systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
+(i.e., when unsigned long is 32-bits). Also fix a bug which caused
+dumpe2fs to incorrectly display block numbers > 32-bits.
+
+Improve the support for integrated quota files (where quota is a first
+class supported feature using hidden files in the ext4 file system).
+Previously the quota file was getting rewritten even when it was not
+necessary, and e2fsck would erroneously try to hide quota files which
+were already hidden.
+
+Quiet complaints in e2fsck when the total free blocks or inodes are
+incorrect in the superblock after an system crash, since we don't
+update nor depend on the superblock summaries at each commit boundary.
+
+Fixed a regression introduced in 1.42.2 which would cause applications
+outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
+would were still using the legacy 32-bit bitmaps) to crash. This was
+due to missing 32-bit compat code in side the function
+ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
+#808421)
+
+Fix a bug which would cause mke2fs to fail creating the journal if
+/etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
+#3509398)
+
+Updated/fixed various man pages.
+
+Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
+translations
+
+Fixed various Debian Packaging issues.
+
+
+Programmer's Notes
+------------------
+
+Change the nonsensically wrong types in the function signature of the
+inline function ext2fs_find_first_zero_block_bitmap2(). This was
+caused by a cut and paste error; fortunately no code in e2fsprogs used
+this inline function, and there are any users of this functions
+outside of e2fsprogs.
+
+Add support for systems which have valloc(), but which do have
+posix_memalign() nor memalign() (such as MacOS 10.5).
+
+Refactor and clean up the allocation of aligned buffers for Direct I/O
+support. Previously some allocations were requesting a greater
+alignment factor that what was strictly necessary. Also optimize
+reading and writing bitmaps using Direct I/O when the size of the
+bitmap did not fully cover the file system blocksize.
+
+Reserve the codepoints for the INCOMPAT features LARGEDATA and
+INLINEDATA.
+
+Improved the regression test suite by adding some new integration
+tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
+jbd2 format, as well as f_eofblocks which tests the new handling of
+uninitialized and initialized blocks beyond i_size. Also add a new
+unit test which verifies 32-bit bitmaps support and the new
+find_first_zero primitives.
+
+Add a few dependencies to fix parallel (make -j) builds.
+
+Removed bash'isms which were breaking the regression test suite on
+systems where /bin/sh is not bash.
+
+The config.guess and config.sub have been updated to the 2012-02-10
+version.
+
+Fix a portability problem caused by assuming the present of mntent.h
+means that setmntent() exists. Instead, explicitly test for this in
+the configure script.
+
+If the sys/signal.h header file does not exist, don't try to include
+it, since it's not available on all systems.
+
+Add support for systems that do not support getpwuid_r()
+
+The configure script now supports a new option,
+--enable-relative-symlinks, which will install relative symlinks for
+the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
+
+When building BSD shared libraries make sure the LDFLAGS variable is
+passed to the linker. Fixing this allows, for example, e2fsprogs to
+be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
+#3517272)
+
+Fix gcc -Wall nitpicks
+
+
+E2fsprogs 1.42.2 (March 27, 2012)
+=================================
+
+The resize2fs program uses much less CPU and is much faster for very
+large file systems. (Addresses Debian Bug: #663237)
+
+The seti and freei commands in debugfs can now take an optional length
+argument to set and clear a contiguous range of inodes.
+
+E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
+plan to remove support for it from the kernel file system driver. It
+really wasn't very useful and was causing more problems than it
+solves. Since e2fsck will complain if inodes that should have
+EOFBLOCKS_FL do not have the flag set, we are going to remove this
+check from e2fsprogs first, and then only remove the flag from the
+kernel much later.
+
+The mke2fs program can now use direct I/O via "mke2fs -D". This will
+slow down the mke2fs, but it makes it more polite on a loaded server
+by limiting the amount of memory that gets dirtied by mke2fs when it
+is using buffered I/O.
+
+E2fsck was needlessly closing and re-opening the file system as a side
+effect of adding Multiple Mount Protection (MMP). This isn't
+necessary for non-MMP file systems, so drop it.
+
+Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
+can more easily diagnose memory allocation failures caused by
+insufficient memory. E2fsck will now abort if there are memory
+allocation failures when the file system is initially opened and
+during the block group descriptor checks. (Addresses Google Bug:
+#6208183)
+
+If there are incorrect block group checks, e2fsck will now report the
+incorrect and corrected checksum values.
+
+The e2fsck progam can now write log files containing the details of
+the problems that were found and fixed directly, via configuration
+parameters in /etc/e2fsck.conf.
+
+Added the ability to limit the number of messages reported by e2fsck
+for a given problem type. This avoids a potential bottleneck if there
+is a serial console which can cause a boot sequence to take a long
+time if e2fsck needs to report many, many file system errors.
+
+The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
+them to use much less memory for large file systems.
+
+The dumpe2fs program will now print the expected block group checksum
+if it is incorrect. This helps to diagnose problems caused by
+incorrect block group checksums.
+
+E2fsck now checks for extents with a zero length, since the kernel
+will oops if it comes accross such a corrupted data structure. (See
+https://bugzilla.kernel.org/show_bug.cgi?id=42859)
+
+E2fsck has a number of bugs relating to discard that have been fixed.
+(1) Fixed a bug which could cause e2fsck to discard portions of the
+inode table which were actually in use. (2) E2fsck will now avoid
+using discard if the block device doesn't zero data on discard, since
+otherwise this could cause problems if the file system gets corrupted
+in the future. (3) E2fsck will now avoid using discard when it is run
+in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
+discards in the last block group.
+
+E2fsck's CPU utilization in pass 5 has been optimized, which will
+speed up e2fsck slightly.
+
+E2image will now skip copying uninitialized bitmap and inode table
+blocks.
+
+Fixed mke2fs -S so it does not corrupt the first block group's
+information.
+
+E2fsck will now check the new sysfs interface to determine if we are
+using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
+
+Updated/fixed various man pages. (Addresses Debian Bug: #665427)
+
+Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
+
+Programmer's Notes
+------------------
+
+Fixed various portability issues for non-Linux systems, particularly
+MacOS X, as well as Linux systems running with the just-released glibc
+2.15.
+
+Fix file descriptor leak in ext2fs_close() if the file system with
+uninit_bg is opened read/only with a backup superblock. (Addresses
+SourceForge Bug: #3444351)
+
+Fixed an invalid return in a non-void function in the quota code.
+(Addresses SourceForge Bug: #3468423)
+
+Fixed the debian rules file so that the calls to dpkg-buildflags works
+when the shell is dash.
+
+The debian package build now uses V=1 so that there is more
+information about potential build failures in debian buildd logs.
+
+If the uninit flags get cleared by functions such as
+ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
+superblock is marked dirty and the block group descriptor checksum is
+updated if necessary.
+
+The debian rules file will now try to load debian/rules.custom of it
+exists. This flie can skip various builds for speed reasons if there
+is no need for the e2fsck-static or udeb packages. Available
+customizations in the rules file includes SKIP_STATIC=yes,
+SKIP_BF=yes, and SKIP_DIETLIBC=yes.
+
+In addition, if the file misc/mke2fs.conf.custom.in exists in the
+source tree, it will be used instead of the standard misc.conf file in
+the upstream sources. This makes it easier for Debian-derived systems
+to distribute a custom mke2fs.conf file without having to worry about
+merge issues if future versions of e2fsprogs makes changes in the
+upstream default version of mke2fs.conf.
+
+
+E2fsprogs 1.42.1 (February 17, 2012)
+===================================
+
+The mke2fs and e2fsck now use significantly less memory when creating
+or checking very large file systems. This was enabled by adding
+extent-based bitmaps which are stored using a red-block tree, since
+block and inode allocations tend to be contiguous.
+
+The command mke2fs -S is used as a last ditch recovery command to
+write new superblock and block group descriptors, but _not_ to destroy
+the inode table in hopes of recovering from a badly corrupted file
+system. So if the uninit_bg feature is enabled, mke2fs -S will now
+set the unused inodes count field to zero. Otherwise, e2fsck -fy
+after using mke2fs -S would leave the file system completely empty.
+
+Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
+honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
+installed an mke2fs binary using that name.
+
+The usage and help messages for the -G, -t and -T options in mke2fs
+have been fixed.
+
+If e2fsck needs to use the backup group descriptors, the
+ext2fs_open2() function clears the UNINIT bits to ensure all of the
+inodes in the file systems get scanned. However, the code which reset
+the UNINIT flags did not also recalculate the checksum, which produced
+many spurious (and scary) e2fsck messages. This has been fixed by
+resetting cheksums when the UNINIT bits are cleared.
+
+Relax a check in e2fsck which required that the block bitmap to be
+initialized when the inode bitmap is in use. This will allow us to
+eventually eliminate code from the kernel which forcibly initialized
+the block bitmap when the inode bitmap is first used, requiring an
+extra journal credit and disk write. (Addresses Google Bug: #5944440)
+
+Make sure rdebugfs (which may be installed setuid or setgid disk) does
+not honor environment variables if euid != uid or egid != gid.
+
+Debugfs's ncheck command has been optimized and now is much more
+robust with faced with corrupted file systems. The ncheck command
+also now has a -c option which will verify the file type information
+in the directory entry to see if matches the inode's mode bits. This
+is extremely useful when trying to use debugsfs to determine which
+parts of the file system metadata can be trusted.
+
+E2image will try to use ftruncate64() to set the i_size for raw
+images, instead of writing a single null byte. This avoid allocating
+an extra block to the raw image, for those file systems and/or
+operating systems that support this. (Linux does.) In addition, fix
+a logic bug that caused the file to not be properly extended if the
+size of the last hole was exactly an multiple of a megabyte.
+
+Fixed a bug in resize2fs where for 1k and 2k file systems, where
+s_first_data_block is non-zero, this wasn't taken into account when
+calculate the minimum file system size for use with the -M option.
+
+Fixed the badblocks program to honor the -s flag when in read-only -t
+mode. (Addresses Debian Bug #646629)
+
+Update Czech, Dutch, French, Polish, and Sweedish translation from the
+Translation Project.
+
+Fixed various Debian Packaging issues so that dpkg-buildflags is used
+if present, which allows e2fsprogs to be built with security hardening
+flags. (Addresses Debian Bugs: #654457)
+
+Programmer's Notes
+------------------
+
+Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
+This was only an issue for programs compiled against e2fsprogs 1.41
+that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
+#3451486)
+
+The libext2fs library now uses sysconf() to fetch the page size, instead
+of the deprecated getpagesize().
+
+The ext2fs_get_pathname() function will return a partial path if an a
+directory in the path is not a directory, displaying it as an inode
+number in angle brackets instead of giving up and displaying an error.
+This is much more helpful when a user is trying to debug a corrupted
+file system.
+
+Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
+
+Added a new library function, ext2fs_file_get_inode_num(), for use by
+fuse2fs.
+
+Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
+file, it actually works.
+
+The block iterator now properly honors the BLOCK_ABORT flag for
+extent-based flags. Previously, it didn't, which generally made code
+be less efficient, but it could cause bugs in ext2fs_link(), for
+example, by causing it to insert multiple directory entries.
+
+Fixed an (harmless other than causing a compiler warning) use of an
+uninitialized variable in e2fsck's MMP code.
+
+
+E2fsprogs 1.42 (November 29, 2011)
+==================================
+
+This release of e2fsprogs has support for file systems > 16TB. Online
+resize requires kernel support which will hopefully be in Linux
+version 3.2. Offline support is not yet available for > 16TB file
+systems, but will be coming.
+
+This release of e2fsprogs has support for clustered allocation. This
+reduces the number of block (now cluster) bitmaps by allocating and
+deallocating space in contiguous power-of-2 collections of blocks,
+which are called clustered. This is a file system level feature,
+called 'bigalloc', which must be enabled when the file system is
+initially formatted. It is not backwards compatible with older
+kernels.
+
+Added support for the Multi-Mount Protection (MMP) feature.
+
+E2fsck more efficiently uses scratch files for really big file
+systems. (This is a feature that has to be turned on explicitly; see
+[scratch_files] in the e2fsck.conf man page.)
+
+Fix a bug in e2fsck where if the free blocks and inodes counts are
+incorrect, e2fsck would fix them without printing an error message.
+This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
+any explanation of what was fixed.
+
+E2fsck will no longer attempt to clone an extended attribute block in
+pass1b handling if the file system does not support extended
+attributes.
+
+E2fsck will be more careful accidentally asking the user to continue
+if the file system is mounted, so that an escape sequence won't cause
+a false positive. (Addresses Debian Bug: #619859)
+
+E2fsck now uses less cpu time in pass 5 when large portions of the
+bitmaps are uninitialized.
+
+E2fsck will no longer segault when a corrupted file system has a bad
+extent, and removing it leads to a block needing to be deallocated.
+(Addresses SourceForge Bug: #2971800)
+
+E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
+and print debugging information to make it easier to find potential
+problems.
+
+E2fsck will check to see if the bad block inode looks insane, and will
+skip trying to use if it certain fields which should be zero look
+non-zero. This is to avoid a corrupted bad block inode causing e2fsck
+to get confused and do more harm than good.
+
+If e2fsck modifies certain superblock fields which the kernel doesn't
+look at, it will now mark the superblock as dirty without marking the
+file system as changed. This avoids signalling the init scripts that
+a reboot is necessary, since the kernel isn't going to look at those
+fields, so it won't care if they have been changed.
+
+Fixed a bug in the libext2fs library (in the binary search routine of
+the icount abstraction) that could (very, very rarely) cause e2fsck to
+die in the middle of pass 1 or pass 2 processing.
+
+E2fsck will not try to do a discard operation if the -n option was
+specified on the command line.
+
+E2fsck now supports an extended "discard" option which will cause
+e2fsck to attempt discard all unused blocks after a full, successful
+file system check.
+
+E2fsck will check for the bad block inode to make sure it looks sane
+before trusting it, to avoid causing more harm than good to the file
+system.
+
+E2fsck now returns additional status bits in its exit code if it
+aborts early in the e2fsck run.
+
+E2fsck now correctly calculates the maximum file size in the case of
+the huge_file file system feature enabled without extents.
+
+The mke2fs and e2fsck programs now tries to use the punch hole command
+as a "discard" when operating on normal files.
+
+The e2image program now supports the qcow2 format, which is a more
+efficient way of capturing file system dumps.
+
+Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
+per-device defaults to be specified in the configuration file.
+
+Mke2fs now supports the reserved_ratio relation in the [defaults] and
+[fs_types] section in mke2fs.conf.
+
+Mke2fs now creates extent-mapped directories for the root and
+lost+found directories.
+
+Mke2fs will skip zero'ing the journal if the extended option
+"lazy_journal_init" is specified. This can save a lot of time, but it
+does add a small amount of risk if the system crashes before the
+journal is overwritten entirely once. It is epsecially useful for
+testing.
+
+Mke2fs will now create file systems that enable user namespace
+extended attributes and with time- and mount count-based file
+system checks disabled.
+
+Mke2fs will not set a stride or strip size of one block based on block
+device attributes obtained from sysfs.
+
+Mke2fs now displays a progress report during the discard process.
+
+Mke2fs now handles extreme file system parameters correctly which
+previously caused the inodes per group to drop below 8, leading to a
+segfault. (The inodes per group must be a multiple of 8, but the code
+didn't correctly deal with an inodes per group count less than 8.)
+
+Mke2fs and tune2fs previously would give an error if the user tried
+setting the stride and stripe-width parameters to zero; but this is
+necessary to disable the stride and stripe-width settings. So allow
+setting these superblock fields to zero. (Addresses Google Bug:
+#4988557)
+
+Mke2fs now gives a warning if the auto-detected block size exceeds the
+system's page size.
+
+If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
+is the default), mke2fs will now set the s_max_mnt_count superblock
+field to -1, instead of 0. Kernels older then 3.0 will print a
+spurious message on each mount then they see a s_max_mnt_count set to
+0, which will annoy users. (Addresses Debian Bug: #632637)
+
+The default mke2fs.conf now has entries for "big" and "huge", which
+are needed for very big file systems.
+
+The resize2fs program now has support for a new online resize ioctl
+that can support file systems > 16TB, once it arrives in v3.x kernels.
+
+Fixed bug which caused resize2fs to fail when shrinking an empty file
+system down to its minimal size. (Addresses Sourceforge Bug #3404051)
+
+Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
+
+Allow tune2fs to remove external journals if the device can not be
+found.
+
+Debugfs's icheck will now correctly find inodes which use the
+searched-for block as an extended attribute block.
+
+Debugfs now has a new "punch" command which remove blocks from the
+middle of an inode.
+
+Debugfs now has a new "e2freefrag" command which analyzes the free
+space fragmentation of the file system, using the same code as the
+e2freefrag program.
+
+Debugfs now has a "filefrag" command which displays information about
+a file's fragmentation.
+
+Add support to build a metadata-only, read-only, stripped-down version
+of debugfs called rdebugfs.
+
+Fixed a potential stack overrun bug in debugfs.
+
+The badblocks program now correctly recovers from I/O errors when
+direct I/O is being used. The badblocks command now also supports a
+-B option which forces the use of buffered I/O, and the -v option will
+provide a more detailed breakdown of read, write, and failed
+comparison errors.
+
+Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
+
+Added support for journals larger than 2GB.
+
+Support using both hard links and symlinks when installing e2fsprogs.
+
+Add overflow checking to tune2fs -i's fsck interval, which must fit in
+a 32-bit field.
+
+The debugfs command now has a new 'blocks' command which prints out
+data blocks of a particular inode in a format which is useful for
+scripting.
+
+Filefrag will report 0 extents correctly in verbose mode. (Addresses
+RedHat Bugzilla: #653234)
+
+Filefrag has been fixed so its -v report prints the correct expected
+block number (previously there had been an off-by-one error). In
+addition, it will now display the number of contiguous extents when -v
+is not specified. This makes it consistent with the number of extents
+printed when the -v option was specified. In addition, the number of
+contiguous extents is far more interesting/useful than the number of
+physical extents for very large files. (Addresses Debian Bug:
+#631498, #644792)
+
+Logsave's usage message has been fixed. (Addresses Debian Bug:
+#619788)
+
+Avoid an infinite loop in ext2fs_find_block_device() if there are
+symlink loops in /dev caused by a buggy udev.
+
+Added a useful "fallocate" program to the contrib directory.
+
+Fixed an ABI compatibility problem in libext2fs which broke the dump
+program. Also added back some macros which dump needed so it could
+compile against the latest version of ext2_fs.h (Addresses Debian Bug:
+#636418)
+
+Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
+Debian Bug: #641667)
+
+Added internationalization support for libcom_err error table strings.
+
+Fixed various spelling mistakes found in various output strings found
+by I18N translators.
+
+Update translations: French, Chinese, Germany, Indonesian, Swedish,
+Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
+#620659)
+
+Fixed various Debian Packaging issues. (Addresses Debian Bugs:
+#614662, #632169, #641838, #627535, #629355)
+
+Updated/clarified man pages. (Addresses Debian Bugs: #639411,
+#642193, #634883)
+
+Programmer's Notes
+------------------
+
+Initial support for quota as an integrated feature, where the quota
+files are hidden system files that are automatically maintained by
+e2fsck is present, although disabled by default. It must be enabled
+by using the configure option --enable-quota.
+
+Reserved the on-disk fields for the metadata checksum and snapshot
+features, which are currently in development.
+
+The ext2fs library now has the new functions ext2fs_punch(),
+ext2fs_get_memzero() and ext2fs_file_get_inode().
+
+The ext2fs library now has support for calculating the crc32c checksum
+(via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
+
+The I/O manager now supports the discard operation.
+
+Reserved file system code points for new 1st class quota feature.
+
+Shortened the compilation lines by moving the autoconf defines to
+a config.h header file.
+
+Fixed a potential free of an unitialized pointer in
+ext2fs_update_bb_inode().
+
+Fixed miscellaneous gcc -Wall and coverity warnings.
+
+Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
+
+Fixed a build failure when OMIT_COM_ERR is defined.
+
+Improved error checking and fixed memory leaks caused by error return
+paths.
+
+Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
+the fsync() to be skipped.
+
+Added a test for extent-mapped journals by mke2fs and tune2fs.
+
+Added a test for creating a large (over 4GB) journal using mke2fs.
+
+Added a test to make sure the inode size remains constant.
+
+The regression test script now prints the list of which tests failed.
+
+The regression test system now uses /tmp for its scratch files, which
+is often a tmpfs mounted file system and hence much faster.
+
+The i_e2image test was fixed so it works with valgrind.
+
+Tests that rely on debugfs are now skipped if debugfs wasn't built.
+
+Fixed the dependencies for "make check" so all required dependencies
+are built before running the gression tests.
+
+A link to com_err.h is installed in $(includedir) during a "make install".
+
+The po/*.gmo files are automatically rebuilt if they are missing or
+out of date. This helps out Debian packaging.
+
+Allow ext2fs_get_memalign() to compile on systems that don't have
+posix_memalign().
+
+Fixed a namespace leak in libext2fs (tdb_null).
+
+
+E2fsprogs 1.41.14 (December 22, 2010)
+=====================================
+
+Fix spurious complaint in mke2fs where it would complain if the file
+system type "default" is not defined in mke2fs.conf.
+
+The resize2fs program will no longer clear the resize_inode feature
+when the number reserved group descriptor blocks reaches zero. This
+allows for subsequent shrinks of the file system to work cleanly for
+flex_bg file systems.
+
+The resize2fs program now handles devices which are exactly 16T;
+previously it would give an error saying that the file system was too
+big.
+
+E2fsck (and the libext2fs library) will not use the extended rec_len
+encoding for file systems whose block size is less than 64k, for
+consistency with the kernel.
+
+Programming notes
+-----------------
+
+E2fsprogs 1.41.13 would not compile on big-endian systems. This has
+been fixed. (Addresses Sourceforge Bug: #3138115)
+
+The ext2fs_block_iterator2() function passed an incorrect ref_offset
+to its callback function in the case of sparse files. (Addresses
+Sourceforge Bug: #3081087)
+
+Fix some type-punning warnings generated by newer versions of gcc.
+
+
+E2fsprogs 1.41.13 (December 13, 2010)
=====================================
+E2fsck now supports the extended option "-E journal_only", which
+causes it to only do a journal replay. This is useful for scripts
+that want to first replay the journal and then check to see if it
+contains errors.
+
+E2fsck will now support UUID= and LABEL= specifiers for the -j option
+(which specifies where to find the external journal). (Addresses
+Debian Bug #559315)
+
+E2fsck now has support for the problems/<problem code>/force_no
+configuration option in e2fsck.conf, which forces a problem to not be
+fixed.
+
+Dumpe2fs will now avoid printing large negative offsets for the bitmap
+blocks and instead print a message which is a bit more helpful for
+flex_bg file systems.
+
+Mke2fs will now check the file system type (specified with the -t
+option) to make sure it is defined in the mke2fs.conf file; if it is
+not, it will print an error and abort. If the usage type (specified
+with the -T option) is not defined in mke2fs.conf, mke2fs will print a
+warning but will continue. (Addresses Debian Bug #594609)
+
+Clarified error message from resize2fs clarifying that on-line
+shrinking is not supported at all. (Addresses Debian Bug #599786)
+
+Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
+displayed. (Addresses Debian Bug #555456)
+
+E2fsck will open the external journal in exclusive mode, to prevent
+the journal from getting truncated while it is in use due to a user
+accidentally trying to run e2fsck on a snapshotted file system volume.
+(Addresses Debian Bug #587531)
+
+Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
+flag.
+
+The tune2fs program can now set the uninit_bg feature without
+requiring an fsck.
+
+The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
+default mount options settings which were added in 2.6.35.
+
+The e2fsck and dumpe2fs programs now support the new ext4 superblock
+fields which track where and when the first and most recent file
+system errors occurred. These fields are displayed by dumpe2fs and
+cleared by e2fsck. These new superblock fields were added in 2.6.36.
+
+Debugfs now uses a more concicse format for listing extents in its
+stat command. This format also includes the interior extent tree
+blocks, which previously was missing from stat's output for
+extent-based files.
+
+Debugfs has a new option, -D, which will request Direct I/O access of
+the file system.
+
+Mke2fs will skip initializing the inode table if a device supports
+discard and the discard operation will result in zero'ed blocks.
+
+Badblocks will now correctly backspace over UTF-8 characters when
+displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
+Debian Bugs #583782 and #587834)
+
+E2freefrag will now display the total number of free extents.
+
+Resize2fs -P no longer requires a freshly checked filesystem before
+printing the minimum resize size.
+
+Fixed a floating point precision error in a binary tree search routine
+that can lead to seg fault in e2fsck and resize2fs.
+
+Fixed a bug in e2fsck where if both the original and backup superblock
+are invalid in some way, e2fsck will fail going back to the original
+superblock because it didn't close the backup superblock first, and
+the exclusive open prevented the file system from being reopened.
+
+Fixed a big in e2freefrag which caused getopt parsing to fail on
+architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
+
+Clarified an mke2fs error message so a missed common in an -E option
+(i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
+results in a more understandable explanation to the user.
+
+Mke2fs now displays the correct valid inode ratio range when
+complaining about an invalid inode ratio specified by the user.
+
+Mke2fs now understands the extended option "discard" and "nodiscard",
+and the older option -K is deprecated. The default of whether
+discards are enabled by default can be controled by the mke2fs.conf
+file.
+
+Mke2fs's handling of logical and physical sector sizes has been
+improved to reflect the fact that there will be some SSD's with 8k and
+16k physical sectors arriving soon. Mke2fs will no longer force block
+size to be the physical sector size, since there will be devices where
+the physical sector size is larger than the system's page size, and
+hence larger than the maximal supported block size. In addition, if
+the minimal and optimal io size are not exported by the device, and
+the physical sector size is larger than the block size, the physical
+sector size will be used to set the Raid I/O optimization hints in the
+superblock.
+
+E2fsck will now display a better, more specific error message when the
+user enters a typo'ed device name, instead of blathering on about
+alternate superblocks.
+
+Fixed various Debian Packaging Issues
+
+Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
+#589345, #591083; Addresses Launchpad Bug: #505719)
+
+Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
+Polish, Swedish, and Vietnamese translations.
+
+
+Programmer's Notes
+------------------
+
+Fix a dependency definition for the static and profiled blkid
+libraries which could cause compile failures in some configurations.
+(Addresses Debian Bug: #604629)
+
+Add support for Direct I/O in the Unix I/O access layer.
+
+Fixed a memory leak in the Unix I/O layer when changing block sizes.
+
+Fixed minor memory leaks in mke2fs.
+
+Added a new function to the ext2fs library, ext2fs_get_memalign().
+
+The tst_super_size test program will check to make sure the superblock
+fields are correctly aligned and will print them out so they can be
+manually checked for correctness.
+
+Fixed some makefile dependencies for test programs in lib/ext2fs.
+
+Reserved the feature flags and superblock fields needed for the Next3
+snapshot feature.
+
+Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
+EXT4_INCOMPAT_EA_INODE.
+
+
+E2fsprogs 1.41.12 (May 17, 2010)
+================================
+
+Mke2fs now gives a correct error message if the external journal
+device is not found. (Addresses Red Hat Bug #572935)
+
+Resize2fs -P will now refuse to print a minimum size if the file
+system is not clean. Previously it would go ahead and print a minimum
+size anyway, which might not be correct, leading to user confusion.
+
+E2fsck now tests for extents that begin at physical block 0 and
+rejects them as invalid. (Addresses Google Bug: #2573806)
+
+Fixed a bug in e2fsck which could cause it to crash when trying to
+remove an invalid extent and the block bitmaps hadn't yet been loaded.
+(Addresses SourceForge Bug: #2971800)
+
+E2fsck now will completely skip time-based checks if the system clock
+looks insane or the option broken_system_clock is set in
+/etc/e2fsck.conf.
+
+E2fsck would previously report an i_blocks corruption for a 4T file
+created using posix_fallocate; this bug has been fixed.
+
+E2fsck will now correctly mark a sparse journal as invalid and will
+delete and recreate the journal to address the problem.
+
+E2fsck would previously incorrectly ask the user whether she would
+like to abort the file system check after finding a problem --- and
+then abort regardless of the user's answer. This is annoying, and
+has been fixed.
+
+E2fsck can now continue even if it fails to recreate the resize
+inode; previously it would just abort the file system check
+altogether.
+
+E2fsck could potentially remove directory entries for inodes found in
+the unused region of the inode table; this would generally happen on
+ext4 file systems that do not use journaling. This bug has been fixed
+by not clearing these directory entries once it has been established
+that bg_unused_inodes may not be trustworthy; once pass #2 has been
+completed, e2fsck will restart the file system check from the
+beginning, and then it will be safe to delete any directory entries
+pointing to inodes that appear to be deleted. (Addresses Google Bug:
+#2642165)
+
+E2fsck will not try to set the block group checksums if the user
+cancels the fsck with a control-C. It's a bad idea to set the
+checksums if e2fsck hasn't been completed, and it often results an the
+error message, "Inode bitmap not loaded while setting block group
+checksum info". (Addresses Launchpad Bug: #582035)
+
+The mke2fs program now queries the kernel for the physical as well as
+the logical sector size, and will not allow a blocksize below the
+logical, and will strongly encourage a blocksize at least as big as
+the physical blocksize. This is needed for 4k sector drives that
+emulate 512 byte sector sizes.
+
+Mke2fs will now allow a flex_bg size of 1. This is unusual, and
+rarely needed, but it is a legal value.
+
+E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
+not needed, and offer to clear it; this is a sign of a kernel bug, but
+more importantly, some released kernels may crash when this situation
+is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
+
+E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
+i_size is correct. (Kernels starting with 2.6.34 will set
+EOFBLOCKS_FL.)
+
+The com_err library will now only output ^M (a CR character) when the
+tty is in raw mode.
+
+Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
+and Vietnamese translations.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #571247, #563487)
+
+
+Programmer's Notes
+------------------
+
+The regression test suite now uses its own mke2fs.conf file, so that
+downstream distributions want change the mke2fs.conf file which is
+distributed in the RPM or dpkg file, without worrying about screwing
+up the regression test results.
+
+Always build namei.o so that building with configure --disable-debugfs
+works correctly. Long-term, if we care about reduced e2fsprogs
+builds, we need a more general solution for deciding what .o files are
+needed for a particular build. Given that install floppies are going
+(gone?) the way the dodo bird, we probably don't care, though.
+(Addresses Sourceforge Bug: #2911433)
+
+Add configure options --enable-symlink-build and
+--enable-symlink-install, which allow e2fsprogs be built using
+symlinks instad of hard links, and to be installed using symlinks
+instead of hard links, respectively. It is useful when the file
+system where the build is taking place, or the file system where
+e2fsprogs is installed, can't handle hard links for some reason.
+(Addresses Sourceforge Bug: #1436294)
+
+Fixed compile warning in mke2fs.c.
+
+
+E2fsprogs 1.41.11 (March 14, 2010)
+==================================
+
+E2fsck will no longer give a fatal error and abort if the physical
+device has been resized beyond 2**32 blocks. (Addresses Launchpad
+Bug: #521648)
+
+Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
+the allocation status of the block <blk>. (Addresses Debian Bug:
+#564084)
+
+E2fsck now prints a much more emphatic and hopefully scary message
+when a file system is detected as mounted while doing a read/write
+check of the filesystem. Hopefully this will dissuade users from
+thinking, "surely that message doesn't apply to *me*" :-(
+
+E2fsck -n will now always open the file system read-only. We now
+disallow certain combination of options which previously were manual
+exceptions; this is bad because it causes users to think they are
+smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
+-D" are no longer supported. (Addresses Launchpad Bug: #537483)
+
+In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
+it detected a badly aligned partition. Unfortunately, this broke some
+distribution installation scripts, so it now just prints the warning
+message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
+Launchpad Bug: #530071)
+
+Mke2fs would take a long time to create very large journal files for
+ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
+now fixed.
+
+E2fsck now understands the EOFBLOCKS_FL flag which will be used in
+2.6.34 kernels to make e2fsck not complain about blocks deliberately
+fallocated() beyond an inode's i_size.
+
+E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
+e2fsck -fD can corrupt non-indexed directories when are exists one or
+more file names which alphabetically sort before ".". This can happen
+with ext2 filesystems or for small directories (take less than a lock)
+which contain filenames that begin with a space or some other
+punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
+Bug: #525114)
+
+
+Programmer's Notes
+------------------
+
+Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
+correctly.
+
+The libcom_err function now has support for Heimdal's com_right_r
+function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian
+Bug: #558910)
+
+
+E2fsprogs 1.41.10 (February 7, 2010)
+====================================
+
+Fix resize2fs bug which causes it to access invalid memory.
+
+Add libss support for libreadline.so.6.
+
+Fix e2fsck's check for extent-mapped directory with an incorrect file
+type.
+
+Add new e2fsck.conf configuration option, default/broken_system_clock
+to support systems with broken CMOS hardware clocks. Also, since too
+many distributions seem to have broken virtualization scripts now,
+e2fsck will by default accept dates which are off by up to 24 hours by
+default. (Addresses Debian Bugs: #559776, #557636)
+
+Fix a bug where mke2fs may not use the best placement of the inode
+table when there is only room for a single block group in the last
+flex_bg.
+
+E2fsck is now smarter when it needs to allocate blocks in the course
+of fixing file system problems. This reduces the number of spurious
+differences found in pass #5.
+
+E2fsck will no longer rehash directories which fit in a single
+directory block.
+
+E2fsck now correctly handles holes in extent-mapped directories (i.e.,
+sparse directories which use extents).
+
+Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
+
+Fix a bug in filefrag where on platforms which can allow file systems
+with 8k blocks, that it doesn't core dump when it sees a file system
+with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
+out.)
+
+E2fsck will correctly fix directories that are have an inaccurate
+i_size as well as other problems in a single pass, instead of
+requiring two e2fsck runs before the file system is fully fixed.
+
+Fix e2fsck so it will correctly find and detect duplicate directory
+entries for non-indexed directories. ( Addresses Sourceforge Bug:
+#2862551)
+
+Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
+thinly-provisioned storage device. This can be disabled using the -K
+option.
+
+Enhance libext2fs so it works around bug in Linux version 2.6.19
+and earlier where the /proc/swaps file was missing the header on
+the first line.
+
+Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
+was missing the header on the first line.
+
+Fix some big-endian bugs in e2fsck and libext2fs.
+
+Fix resize2fs so it works correctly on file systems with external
+journals instead of failing early with the error "Illegal inode
+number".
+
+Fix libss so that it does not seg fault when using a readline library
+which does not supply a readline_shutdown() function.
+
+Updated dumpe2fs's usage message so it correctly gives the right
+arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
+(Addresses Launchpad Bug: #448099)
+
+Teach libext2fs to ignore the high 32 bits of the i_blocks field
+when huge_file file system feature is set, but the inode does not
+have the HUGE_FILE_FL flag set.
+
+Fix e2fsck's handling of 64-bit i_blocks fields.
+
+E2fsck will now print "Illegal indirect block", "Illegal
+double-indirect block", etc., instead of "Illegal block #-1" or
+"Illegal block #-2", etc. This makes it easier for users to
+understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
+
+Mke2fs now will obtain get device topology information from blkid and
+use it to populate the superblock stride and stripe sizes. It will
+also warn if the block device is misaligned
+
+Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug:
+##524526)
+
+Fix the libext2fs library code to round up the bitmap size to a 4-byte
+boundary, to prevent spurious seg faults caused by the x86
+architecture. This doesn't affect Linux systems, but was a major
+problem on a number of *BSD systems. (Addresses Sourceforge Bug:
+#2328708)
+
+Fix resize2fs's minimum size required for a file system so it doesn't
+fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131)
+
+Dumpe2fs now prints summary information about the contents of the
+journal.
+
+Avoid printing scary error messages when e2fsck starts running
+problems on low-memory systems, as it tends to panic and mislead the
+user. (Addresses Debian Bug: #509529)
+
+Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
+modules files. (Address Red Hat Bug: #518572)
+
+Fix tune2fs so it can add a journal when an extent-enabled file system
+is mounted. (Addresses Launchpad bug: #416648)
+
+Update Czech, Indonesian, Polish and Vietnamese translations (from the
+Translation Project).
+
+Update/clarify man pages. (Addresses Sourceforge Bug: #2822186)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #540111)
+
+Programmer's Notes
+------------------
+
+The configure script supports the --with-cc, --with-ccopts, and
+--with-ldopts options. Instead, the more standard use of CC=,
+CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
+Also, --with-ld, which never worked, was also removed.
+(Addresses Sourceforge Bug: #2843248)
+
+The in-tree header files are only used if the in-tree uuid or blkid
+libraries are used. Otherwise, use the system-provided uuid or blkid
+header files if using the system-provided libraries.
+
+Fix some build failures caused by --disable-* configure options.
+
+Work around a bug in autoconf 2.64.
+
+
+E2fsprogs 1.41.9 (August 22, 2009)
+==================================
+
+Fix a bug in e2fsck routines for reallocating an inode table which
+could cause it to loop forever on an ext4 filesystem with the FLEX_BG
+filesystem feature with a relatively rare (and specific) filesystem
+corruption. This fix causes e2fsck to try to find space for a new
+portion of the inode table in the containing flex_bg, and if that
+fails, the new portion of the inode table will be allocated in any
+free space available in the filesystem.
+
+Make e2fsck less annoying by only asking for permission to relocate a
+block group's inode table once, instead of for every overlapping
+block. Similarly, only ask once to recompute the block group
+checksums, instead of once for each corrupted block group's checksum.
+
+Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
+not present, and it needs to fall back to using the FIBMAP ioctl.
+
+Fix filefrag to correctly print the number of extents for zero-length
+files. (Addresses Debian Bug: #540376)
+
+Filefrag now has a -B option which forces the use of the FIBMAP ioctl
+to more easily debug the FIBMAP code.
+
+Fixed filefrag for non-extent based files.
+
+Add a new program, e2freefrag, which displays information about the
+free space fragmentation in an ext2/3/4 filesystem.
+
+Fix inode resizing via tune2fs -I so that it works correctly in the
+face of non-empty bad blocks inodes, and if the filesystem was
+formatted using the "mke2fs -E stride=N" option for RAID arrays.
+
+Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
+and corrupt large directories if the directory needs to shrink by more
+than one block. (Addresses Debian Bug: #537510)
+
+Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
+last mount times are in the future, they are corrected even if
+buggy_init_scripts is set. This is needed because otherwise resize2fs
+will refuse to resize the filesystem, even after running "e2fsck -f".
+(Addresses Launchpad bug: #373409)
+
+E2fsck will now print much fuller information when the last mount time
+or last written time is in the future, since most people can't seem to
+believe their distribution has buggy init scripts, or they have a
+failed CMOS/RTS clock battery.
+
+Enhance dumpe2fs to dump the extent information via the 'stat'
+command, and more detailed extent information via the new command
+'dump_extents'.
+
+Update French, Polish, Czech, and Sweedish translation from the
+Translation Project.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details.
+
+Programmer's Notes
+------------------
+
+Fixed miscellaneous gcc -Wall warnings.
+
+Fixed memory leak in error path in ext2fs_block_iterate2()
+
+Fixed non-Linux build of the intl directory by adding support for the
+E/Q/V macros.
+
+The bitmap read/write functions now treat uninitialized bitmaps as
+unallocated; this fixes a number of problems in all e2fsprogs for ext4
+filesystems when there is a need to allocate new blocks or inodes, and
+there aren't any free blocks or inodes in the already-used block
+groups.
+
+Improve ext2fs_extent_set_bmap() to avoid creating new extents which
+get inserted into the extent tree when they are not needed.
+
+
+E2fsprogs 1.41.8 (July 11, 2009)
+================================
+
+Fix resize2fs's online resizing, fixing a regression which in
+e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
+
+Fix potential filesystem corruptions caused by using resize2fs to
+shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
+Bug: #510379)
+
+Optimize uuid_generate() to avoid running uuidd if it is not setuid or
+setgid and the currently running program doesn't have write access to
+the uuidd work directory.
+
+Add safety checks (for non-Linux systems) so that uuidd isn't run with
+file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
+will be careful not to close the file descriptor for its unix domain
+socket when it detaches itself from the controlling tty. Also add
+safety checks so that if the unix domain socket between the uuid
+library and uuidd program is closed for any reason, both the library
+and the uuidd will return an appropriate error code instead of looping
+in an infinite loop.
+
+The e2croncheck script, which creates an LVM snapshot and then checks
+the ext3/4 filesystem via the LVM snapshot, has been added to the
+contrib directory.
+
+Fix filefrag program for files that have more than 144 extents.
+
+Update French, Polish, Czech, Indonsian, and Sweedish translation from
+the Translation Project.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug #535530)
+
+Update/clarify man pages.
+
+Programmer's Notes
+------------------
+
+Fix compilation problem when configured with --disable-uuid.
+
+Don't build uuidgen if configured with --disable-uuid.
+
+Add the new library function ext2fs_test_inode_bitmap_range(), and
+optimized ext2fs_test_block_bitmap_range(), which will be needed for
+future optimizations for e2fsck.
+
+Fix makefile dependencies for libcom_err so that the Makefiles work
+well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
+
+Enhance the build system so that the full set of commands executed by
+the Makefiles are displayed, instead of the Linux kernel summary
+output, if the build was configured with --enable-verbose-makecmds, or
+if GNU make is in use and the V variable is non-null, i.e., via "make
+V=1".
+
+
+E2fsprogs 1.41.7 (June 29, 2009)
+================================
+
+Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
+uninitalized data into the portion of the inode beyond the first 128
+bytes when operating on inodes mapped via extents; potentially
+corrupting filesystems.
+
+Fix memory leaks in e2fsprogs, including a very large memory leak
+which can cause e2fsck to run out of memory when checking very large
+filesystems using extents.
+
+The logsave program will now filter out the ^A and ^B characters when
+writing to the console.
+
+Harden ext2fs_validate_entry() so that lsdel will not read beyond the
+end of the block even if the directory block is corrupted.
+
+Fix debugfs from core dumping if the logdump command fails to open the
+output file.
+
+Enhance badblocks to print the currently tested block number when
+interrupted with ^C.
+
+Fix lsattr to exit with a non-zero status when it encounters errors.
+(Addresses RedHat Bugzilla #489841)
+
+Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
+filesystems as the kernel when encoding rec_len >= 64k. For 64k
+filesystems (currently all that is supported by e2fsprogs, this is
+only a minor corner case).
+
+Resize2fs will now update the journal backup fileds in the sup0erblock
+if the journal is moved; this avoids an unnecessary full fsck after
+resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
+
+Fix libext2fs to properly initialize i_extra_size when creating the
+journal and resize inodes.
+
+Change badblocks to allow block sizes larger than 4k.
+
+Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
+
+Update Chinese and Czech translation from the Translation Project.
+
+Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
+
+
+Programmer's Notes
+------------------
+
+Add --disable-libuuid option to configure which uses an in-system
+installed version of libuuid; the private version is enabled by
+default.
+
+Add --valgrind-leakcheck option to the test_script program which runs
+valgrind with the appropriate options to find memory leaks.
+
+
+E2fsprogs 1.41.6 (May 30, 2009)
+===============================
+
+Fix a critical regression in e2fsck introduced version 1.41.5 which
+can undo updates to the block group descriptors after a journal replay.
+
+If e2fsck receives an I/O error while replaying the journal, prompt
+the user whether they want to ignore the error or not; if e2fsck is
+run in preen mode, force fsck to abort the preen pass.
+
+Fix a bug which would cause e2fsck to core dump if the filesystem
+contains a corrupt extent header, and the user declines to clear the
+inode. (Addresses Sourceforge Bug: #2791794)
+
+Fix e2fsck to restart only once in the case of multiple block groups
+which inodes in use that are in the uninitialized part of the block
+group's inode table.
+
+To reduce user confusion, if the /etc/mtab file is missing
+ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
+new, explicit error code to indicate this case. This will cause
+e2fsck to give a clearer error message when the user is using buggy
+rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
+Bug: #527859)
+
+Fix e2fsck so that if the primary group descriptors are corrupted, but
+the backup superblock is entirely invalid, to go back to using (and
+fixing) the priary group descriptors instead of completely giving up
+on the filesystem. (Addresses Debian Bug: #516820)
+
+Change e2fsck to not abort a preen pass if an inode is found to have
+i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
+kernels (post 2.6.29) will ignore this field. So let's fix it
+automatically during the preen pass instead of forcing the user to fix
+this up manually. (Addresses Debian Bug: #526524)
+
+Add resource tracking for e2fsck passes 1b through 1d.
+
+Speed up e2fsck by eliminating unnecessary journal checks if the
+filesystem is already mounted and doesn't need recovery (since the
+kernel would have run the journal when the filesystem was mounted.)
+Also speed up e2fsck by avoiding unnecessary block group descriptor
+updates in ext2fs_close().
+
+Add support to chattr to migrate inodes from using direct/indirect
+blocks to extents.
+
+Avoid corrupting the filesystem if there is an attempt to shrink a
+filesystem using resize2fs smaller than posible by making
+ext2fs_set_bmap() more careful not to delete the old block until the
+new block can be inserted. In addition, fix a bug in how the minimum
+size of the filesystem (plus a safety margin) is calculated, and
+modify resize2fs to refuse to shrink the filesystem below that minimum
+size without the force flag.
+
+Teach blkid to try to figure out DM device names using take advantage
+of information in sysfs when running on kernels (2.6.29 and later)
+which provide this information in /sys/block/dm-<N>/dm/name; this is
+much faster than scanning for the devncie number in /dev/mapper.
+
+Fix blkid to prefer /dev/mapper/<name> device names instad of the
+private /dev/dm-X names.
+
+Add an -a option to debugfs's close_filesys command which writes any
+changes to the superblock or block group descriptors to all of the
+backup superblock locations.
+
+Add support to the filefrag program to use the FIEMAP ioctl.
+
+Update Chinese translation from the Translation Project.
+
+Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
+Launchpad Bug: #381854)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug #506064)
+
+
+Programmer's Notes
+------------------
+
+Add test code to make sure e2fsck's problem.c doesn't have two problem
+codes assigned to duplicate values.
+
+Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
+(Addresses Sourceforge Bug: #2780205)
+
+Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
+function declaration for init_resource_track() and
+print_resource_track() when RESOURCE_TRACK is not defined.
+
+The test code which is used to build the tst_csum progam has been
+moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
+avoid compile problems caused by not having a prototype for
+ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
+
+Update the config.guess and config.sub file to the latest from the
+FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
+Debian Bug: #528330)
+
+Add a new function, ext2fs_extent_open2(), which behaves like
+pext2fs_extent_open(), but uses the user-supplied inode structure
+when opening an extent instead of reading the inode from disk.
+
+
+E2fsprogs 1.41.5 (April 23, 2009)
+=================================
+
+Fix a number of filesystem corruption bugs in resize2fs when growing
+or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
+is not mounted).
+
+Debugfs can now set i_file_acl_high via the set_inodes_field command,
+and print a 64-bit file acl. This is useful for debugging filesystem
+corruptions where the high bits of i_file_acl_high are set. E2fsck
+will detect and fix non-zero i_file_acl_high on 32-bit filesystems
+since some Linux kernel versions pay attention to this field even when
+they shouldn't.
+
+Speed up e2fsck when checking clean filesystems by avoiding
+unnecessary block reads, and coalescing the block group descriptor
+blocks so they are read using a single read operation.
+
+The libuuid library will now close all file descriptors before running
+uuidd. This avoids problems when the calling program has open sockets
+which then never get closed because uuidd is a long-running helper
+daeomn. (Addresses Launchpad bug: #305057)
+
+In order to avoid unnecessary full filesystem checks by e2fsck after
+an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
+the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
+
+Mke2fs will avoid trying to create the journal when run in
+superblock-only mode (mke2fs -S), since the left-over journal in the
+inode table will cause mke2fs to fail.
+
+Fix a bug in libext2fs functions that check to see if a particular
+device or filesystem image is mounted, which would cause these
+functions to report that a file identical to the (relative) pathname
+used by a pseudo-filesystem was mounted when in fact it was not.
+
+Update Czech translation from the Translation Project.
+
+Add Chinese (simplified) translation from the Translation Project.
+
+Fix support for external journals (which was broken in e2fsprogs
+1.41.4).
+
+Fix a regression in debugfs where the "stat" command when no
+filesystem was open would cause debugfs to crash with a segmentation
+violation.
+
+Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
+used to support filesystems without a journal. Update the blkid
+library so it understands this.
+
+The blkid library will remove an entry from the blkid cache
+representing the entire disk if partitions are found, since presuambly
+the device previously had no partition table, but has now transitioned
+to using a partition table.
+
+Add a check to mke2fs and tune2fs that the argument to the -m option
+(which specifies the reserved ratio) must be greater than zero.
+(Addresses Debian Bug: #517015)
+
+Add support for tracking the number kilobytes written to the
+filesystem via the superblock field s_kbytes_written. It will be
+updated by the kernel as well as by e2fsprogs programs which write to
+the filesystem. This is useful for tracking the wear to filesystems
+on Solid Sstate Drives.
+
+Fix compatibility issue in the libext2fs info file and makeinfo
+version 4.12. (Addresses Red Hat Bugzilla: #481620)
+
+Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug: #506279)
+
+Programmer's Notes
+------------------
+
+Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
+Bug: #521602)
+
+Fix various gcc compilation warnings and other programming cleanups.
+(Addresses Red Hat Bugzilla: #486997)
+
+Add support for building the blkid command statically.
+
+Add support for disabling the built-in blkid library in favor of a
+system-installed blkid implementation via the configure option
+--disable-libblkid.
+
+
+E2fsprogs 1.41.4 (January 27, 2009)
+===================================
+
+Fixed a bug which could sometimes cause blkid to return an exit value
+of zero for a non-existent device (Addresses Debian Bug: #502541)
+
+Blkid will now recognize ext3 filesystems that have the test_fs flag
+set as ext3 filesystems.
+
+The blkid library will now recognize btrfs filesystems and swap
+devices currently used by user-level software suspend.
+
+Tune2fs now updates the block group checksums when changing the UUID
+to avoid causing e2fsck to complain vociferously at the next reboot.
+
+Tune2fs's inode size resizing algorithms have been fixed so it is not
+vastly inefficient for moderate-to-large filesystems, due to some
+O(n**2) and O(n*m) algorithms that didn't scale well at all.
+
+Fix tune2fs's inode resizing algorithm so it will not corrupt
+filesystems laid out for RAID filesystems; in addition, tune2fs will
+refuse to change the inode size for filesystems that have the flex_bg
+feature enabled. (This is a limitation in the current implementation
+of tune2fs -I.)
+
+E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
+filesystems with 32-bit block numbers, when the headers for 64-bit
+block numbers was added. This regression has been fixed.
+
+Debugfs's ncheck command has been fixed to avoid printing garbage
+characters at the end of file names.
+
+Fix resize2fs for ext4 filesystems. Some blocks that that need moving
+when shrinking filesystems with uninit_bg feature would not be moved.
+In addition, blocks and inode table blocks were not being correctly
+freed when shrinking filesystems with the flex_bg feable, which caused
+resize2fs -M to fail. Finally, when blocks are moved, make sure the
+uninitialized flag in extents is preserved.
+
+Fix bug which caused dumpe2fs to abort with an error if run on a
+filesystem that contained an external journal.
+
+Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
+for this in argv[0] to provide better legacy support for these
+distributions. This is a practice that should NOT be continued,
+however.
+
+Mke2fs now has a new option -U, which allows the user to specify the
+UUID that should be used for the new filesystem.
+
+Mke2fs will treat devices that are exactly 16TB as if they were 16TB
+minus one block. This allows users who have read that ext3 supports
+up to 16TB filesystems and who create a 16TB LVM to not get confused,
+since the true limit is really 16TB minus one block.
+
+E2fsck will no longer abort an fsck run if block group has an errant
+INODE_UNINIT flag.
+
+E2fsck now distinguishes between fragmented directories and fragmented
+files in verbose mode statistics and in the fragcheck report.
+
+Fix a bug in e2fsck which casued it double count non-contiguous
+extent-based inodes.
+
+E2fsck will leave some slack space when repacking directories to allow
+room for a few directory entries to be added without causing leaf
+nodes to be split right away.
+
+Fix a bug which caused e2fsck to crash when it comes across a
+corrupted interior node in an extent tree with the error message:
+"Error1: Corrupt extent header on inode XXXXXX"
+
+E2fsck problem descriptions involving the journal are no longer
+referred to as "ext3" problems, since ext4 filesystems also have
+journals.
+
+Fix a long-standing bug in e2fsck which would cause it to crash when
+replying journals for filesystems with block sizes greater than 8k.
+
+Update Catalan translation from the Translation Project.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #503057, #502323, #511207)
+
+Programmer's Notes
+------------------
+
+Fix build of e2fsck.profiled, and add support for building profiled
+binaries in the misc directory if configured with --enable-profile.
+
+The ext2fs_open() function now performs more sanity checks on the
+superblock to avoid potential divide by zero errors by other parts of
+library.
+
+The ext2fs_read_inode_full() function now has a safety check to avoid
+a segmentation fault on corrupted filesystems.
+
+The ext2fs_new_inode() function now has a sanity check so that if the
+s_first_inode field in the superblock is insane, it will return
+EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
+
+To avoid segmentation faults, ext2fs_block_alloc_stats() and
+ext2fs_inode_alloc_stats() now validates the passed inode or block
+number to avoid overrunning an array boundary.
+
+Various signed/unsigned errors for variables containing block numbers
+have been fixed.
+
+Accomodations for gcc's stupidity in not realizing that constant
+strings that do not contain a '%' character are safe to use in format
+strings have been made so that distributions that want to compile
+e2fsprogs with -Werror=format-security have an easier time doing so.
+
+Added a new 64-bit getsize interface, ext2fs_get_device_size2().
+
+Added the utility make-sparse.c to the contrib directory.
+
+The ext2fs_block_iterate2() function now reflects errors from
+ext2fs_extent_set_bmap() to the caller, if the callback tries to
+change a block on an extent-based file, and ext2fs_extent_set_bmap()
+fails for some reason (for example, there isn't enough disk space to
+split a node and expand the extent tree.
+
+The ext2fs_block_iterate2() function will preserve the uninit flag in
+extents when the callback function modifies a block in an extent-based
+file.
+
+E2fsck will now flag filesystems that have an insane s_first_ino field
+in their superblock, and attempt to use a backup superblock to repair
+the filesystem.
+
+
+E2fsprogs 1.41.3 (October 12, 2008)
+===================================
+
+E2fsck has been fixed so it prints the correct inode number for
+uinit_bg related problems.
+
+E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
+is available on linux. This can be disabled via a configuration
+option in /etc/e2fsck.conf.
+
+Fix a file descriptor leak in libblkid when checking to see if an ext4
+or ext4dev module exists.
+
+Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
+while trying to close a filesystem can lead to infinite loops.
+(Addresses Red Hat Bugzilla #465679)
+
+Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
+will cause resize2fs to drop into an infinite loop. (Addresses Red
+Hat Bugzilla: #465984)
+
+Add a check in the Unix I/O functions in libext2fs so that when a
+device is opened read/write, return an error if the device is
+read-only using the BLKROGET ioctl.
+
+Fix debugfs's ncheck command so that it prints all of the names of
+hardlinks in the same directory.
+
+Fix a bug in libblkid so it correctly detects whether the ext4 and
+ext4dev filesystems are available, so that the ext4dev->ext4
+fallback code works correctly.
+
+Programmer's Notes
+------------------
+
+Fix a parallel build problem by making sure util/subst is built before
+trying to build the lib/et directory. (Addresses Sourceforge Bug:
+#2143281)
+
+Updated "make depend" information for crc16.o
+
+
+E2fsprogs 1.41.2 (October 2, 2008)
+==================================
+
+Fix e2fsck's automatic blocksize detection. This fixes a regression
+from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
+specifies a block number using the -b option if the blocksize option
+isn't also specified using -B. Unfortunately, users very commonly
+invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
+superblock; in fack e2fsck will often suggest this kind of command
+line. Oops.
+
+Enhance the debugfs's "ncheck" command so it will print all of the
+pathnames for the specified inodes. (Previously, in some cases ncheck
+might not print a pathname for an inode at all if some of the other
+inodes had multiple hard links.)
+
+Enhance debugfs's "hash" command so the hash seed can be specified via
+a command-line option. In addition, allow the hash algorithm to be
+specified by name instead of just by number.
+
+Fix e2fsck so that we don't accidentally print the translation file's
+header when asking the user a custom question so there is no prompt
+defined for a particular problem record. For example, the question
+"Run journal anyway" will get the PO header tacked on because e2fsck
+erroneously passed the null string to _(). (Addresses Launchpad Bug:
+#246892)
+
+Enhance badblocks so that it can test a normal file which is greater
+than 2GB.
+
+Enhance the badblocks command so that it displays the time and
+percentage complete when in verbose mode. (Addresses Debian Bug:
+#429739)
+
+Fix a potential memory leak in a error handling path in debugfs's
+ncheck function.
+
+Fix a potential memory corruption problem if a memory allocation fails
+in resize2fs.
+
+Fix the usage message for debugfs's logdump command to be consistent
+with its man manpage.
+
+Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
+and Sweedish translation from the Translation Project.
+
+Add documentation for the file I/O functions to the libext2fs.texinfo
+file. (Addresses Debian Bug: #484877)
+
+Update and clarified various man pages. (Addresses Launchpad Bug
+#275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug: #497619)
+
+Programmer's Notes
+------------------
+
+Fix a potential file descriptor leack in libcom_err by setting the
+close-on-exec flag for a fd used for debugging. (Addresses Red Hat
+Bugzilla #464689)
+
+Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
+has been carrying a patch for a long time to prevent a largely
+theoretical race condition if a multi-threaded application adds and
+removes error tables in multiple threads. Unfortunately SuSE's
+approach breaks compatibility by forcing applications to link and
+compile with the -pthread option; using pthread mutexes has
+historically been problematic. We fix this by using sem_post/sem_init
+instead.
+
+Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
+Sourceforge Bug: #2087502)
+
+Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
+libraries when using ELF shared libraries.
+
+Fix ELF shared library when building on systems that don't already
+have the e2fsprogs shared libraries already installed. (Addresses
+Sourceforge Bug: #2088537)
+
+Fix the pkg-config files so they work correctly when linking with
+static libraries and fix the include directory so programs don't have
+to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
+instead. (Addresses Sourceforge Bug: #2089537)
+
+Make sure ext2fs_swab64() is compiled for all platforms, and not just
+for x86. (Addresses Debian Bug: #497515)
+
+Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
+non-x86 platforms. (They had been removed for x86 earlier.)
+
+Fix diet libc compilation support, which had bitrotted due to lack of
+TLC. Fixing this improves general portability.
+
+When installing the link library when using ELF shared libraries,
+avoid using absolute pathnames if the link library and the shared
+library are installed in the same directory. (Addresses Sourceforge
+Bug: #1782913)
+
+Fix gen-tarball so it will work even if the top-level directory has
+been renamed to something other than "e2fsprogs". Also make
+gen-tarball print the size of the resulting tar.gz file.
+
+
+E2fsprogs 1.41.1 (September 1, 2008)
+====================================
+
+Many people are forgetting to update their mke2fs.conf file, and this
+causes ext3, ext4, and ext4dev filesystems won't get created with the
+proper features enabled. We address this in two ways. First, mke2fs
+will issue a warning if there is not definition for an ext3, ext4, or
+ext4dev filesystem and the user is trying to create such a filesystem
+type. Secondly, when installing from a source build, "make install"
+will provide basic configuration file handling for /etc/mke2fs.conf.
+If it exists, and does not mention ext4dev, it will be moved aside to
+/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
+be installed. If the existing /etc/mke2fs.conf file does mention
+ext4dev, then "make install" will install official mke2fs.conf file as
+/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
+they should look to see if any changes need to be merged.
+
+The mke2fs program will now create the journal in the middle of the
+filesystem, since this minimizes seek times on average for fsync-heavy
+workloads. In addition, mke2fs will now create journals using extents
+for filesystems that support them. This results in a more efficient
+encoding for the journal since it eliminates the need for using
+indirect blocks.
+
+The mke2fs program will avoid allocating an extra block to the
+journal. (Addresses Sourceforge Bug: #1483791)
+
+Mke2fs will correctly enforce the prohibition against features
+(specifically read-only features) in revision 0 filesystems. (Thanks
+to Benno Schulenberg for noticing this problem.)
+
+Mke2fs previously would occasionaly create some slightly non-optimally
+placed inode tables; this bug has been fixed.
+
+The mke2fs and tune2fs programs now print the correct usage message
+describing the maximum journal size. (Addresses Debian Bug: #491620)
+
+Add support for setting the default hash algorithm used in b-tree
+directories in tune2fs (from a command-line option) or mke2fs (via
+mke2fs.conf). In addition, change the default hash algorithm to
+half_md4, since it is faster and better.
+
+The blkid library will now recognize MacOS hfsx filesystems, and
+correctly extract the label and uuid for hfs, hfsx, and hfsplus
+filesystems. (Addresses Sourceforge Feature Requests: #2060292)
+
+The blkid library has improved detection of JFS and HPFS filesystems.
+(Addresses Launchpad Bug: #255255)
+
+The blkid library is now much more efficiently handling devicemapper
+devices, mainly by no longer using the devicemapper library. This can
+speed up access for systems with a large number of device mapper
+devices.
+
+Blkid had a number of cache validation bugs in libblkid that have been
+fixed. (Addresses Debian Bug: #493216)
+
+Resize2fs will now properly close out the "updating inode references"
+progress bar so there is a newline printed before printing the final
+"resize is successful" message.
+
+Resize2fs will now correctly handle filesystems with extents and/o
+uninitialized block groups correctly when file/directory blocks need
+to relocated (i.e., when shrinking a filesystem or if the resize_inode
+is not present). To support this, the ext2fs library now supports
+initializing inode and block bitmaps that are not yet initialized when
+allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
+addition, e2fs_block_iterate2() can now support changing the location
+of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
+been optimized to avoid creating unnecessary new extents when updating
+the location of blocks in the extent tree. This will also help out
+e2fsck's recovery of obscurely corrupted filesystems with extents,
+when blocks are claimed by multiple inodes.
+
+Add support for on-line resizing ext4 filesystem with the flex_bg
+filesystem feature. The method for doing so is not optimal, but to do
+a better job will require kernel support.
+
+E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
+debugfs programs to not be able to read e2image files; the signed
+vs. unsigned bug in the code which read bitmaps from the e2image has
+been fixed. (Addresses Debian Bug: #495830)
+
+Resize2fs is now correctly managing the directory in-use counts when
+shrinking filesystems and directory inodes needed to be moved from one
+block group to another. This bug has been around since e2fsprogs
+1.26, and is largely harmless, but does cause a filesystem corruption
+which will be flagged by e2fsck after the filesystem has been shrunk.
+
+E2fsck will no longer issue spurious complaints about the inode size
+caused by very large extent-based files, and by blocks reallocated
+using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
+Kernel Bugzilla: #11341)
+
+Mke2fs will now set the creation timestamp on the lost+found directory
+and the root directory. (More generally, all new inodes created using
+the ext2fs library will correctly set the creation timestamp.)
+
+E2fsck now correctly calculates ind/dind/tind statistics in the
+presence of extent-based files. In addition, "e2fsck -v" will report
+statistics of the depth of extent trees in the filesystem. E2fsck can
+also give an inode fragmentation report using "e2fsck -E fragcheck"
+which can be useful when debugging the kernel block allocation
+routines.
+
+Fix support for empty directory blocks in ext4 filesystems with 64k
+blocksize filesystems.
+
+E2fsck will now print the depth of corrupt htree directories.
+
+Debugfs's htree command now correctly understands extent-based
+directories. It will also print out the minor hash as well as the
+major hash.
+
+Debugfs has a new command which will print the supported features of
+e2fsprogs, to enable scripts to know whether the installed version of
+e2fsprogs can support a specific feature.
+
+Debugfs will now write files using extents for filesystems that
+support them.
+
+The error message printed by "tune2fs -I" if the inode size was too
+small was rather confusing, so it has been improved. Also, we won't
+try to create an undo log until we know that command-line-specified
+parameters such as "tune2fs -I <inode size>" are valid.
+
+Given some filesystems found "in the wild" that had non-zero block
+group checksums even though the uninit_bg/gdt_sum feature was not
+enabled, e2fsck would issue spurious error messages. Teach
+ext2fs_group_desc_csum_verify() to ignore the block group checksum
+entirely if the feature flag is not set. (Addresses Debian Bug:
+#490637)
+
+The blkid program will now print out a user-friendly listing of all of
+the block devices in the system and what they contain when given the
+-L option. (Addresses Debian Bug: #490527)
+
+The filefrag program now has a more accurate calculation for the
+number of ideal extents. (Addresses Debian Bug: #458306)
+
+The test I/O manager is now enabled by default, but its overhead is
+only incurred when it would be enabled via the TEST_IO_FLAGS or
+TEST_IO_BLOCK environment variables.
+
+Typographical errors in various program strings and usage messages
+have been fixed; most of these were pointed out by the e2fsprogs
+message catalog translators. (Thanks, translators!)
+
+Update and clarified various man pages, as well as some typographical
+errors in the libext2fs texinfo file.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details.
+
+Add Indonesian and update French, Polish, Dutch, German, Sweedish,
+Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,

+
+Programmer's Notes
+------------------
+
+Fix portability problem with the badblocks group; for systems that
+don't have nanosleep(), try using usleep() instead.
+
+The "make check" target in the e2fsck directory now sets
+LD_LIBRARY_PATH before running the various e2fsck internal library
+regression tests.
+
+The crc32 regression test in the e2fsck library is now portable to
+greater varienty of environments, including big-endian systems and
+when cross-building e2fsprogs for embedded systems. (Addresses
+Sourceforge Bug: #2019287)
+
+The ext2fs_extent_set_bmap() had some bugs when setting the first
+block in a file, or when replacing a single block extent. Those cases
+fortunately were came up relatively rarely when e2fsck was checking
+files, but caused some problems when resize2fs was shrinking
+extent-based files.
+
+Fix a potential core-dumping bug in libe2p's iterate_on_dir()
+function.
+
+Various ext2fs library functions --- ext2fs_block_iterate2(),
+ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
+allocated memory to avoid memory leaks in all of their error return
+paths.
+
+Ext2ed was failing to build because masix support had been removed in
+the rest of e2fsprogs, so ext2ed no longer has masix support, either.
+
+The configure script now respects the LDFLAGS environment variable if
+it is set when configure is called. (Addresses Sourceforge Feature
+Request: #1937287)
+
+Libuuid is now more portable to the Windows platform. (Addresses
+Sourceforge Feature Request: #1937287)
+
+The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
+bare echo commands so that configure flags such as --quiet work
+correctly. (Addresses Sourceforge Patches: #2058794)
+
+A few uses of sprintf have been removed from the ext2fs library to
+make life easier for bootloaders with a limited libc environment.
+(Addresses Sourceforge Bug: #2049120)
+
+The ext2fs_read_inode() checks the validity of the inode number passed
+to it earlier, to avoid doing some needless work when it would fail
+anyway.
+
+The ext2fs_open() checks the validity of the blocksize parameter
+passed to it earlier, to avoid doing some needless work when it would
+fail anyway.
+
+Disable a very annoying automatic "%.sh -> %" GNU make rule in the
+top-level Makefile. That automatic rule is used to better support
+SCCS, but it caused problems for a particular niche distribution which
+likes to use configure.sh files to store the configure options used to
+build a package. Unfortuntaely GNU make will use the configure.sh to
+replace the configure script, resulting in a self-inflicted fork bomb
+leading to an out-of-memory crash.
+
+To support old GNU C compilers don't use C99/C++ comments, but only
+K&R style comments, and don't try to use __builtin_expect if __GNUC__
+is less than 3. (__builtin_expect is only supported for gcc versions
+2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
+this is an optimization, we only try to use __builtin_expect for gcc 3
+and up.)
+
+In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
+__LITTLE_ENDIAN, which are only defined by glibc's header files and
+hence isn't portable.
+
+For the convenience for some distributions that need a static tune2fs,
+the Makefile for misc/ now has a tune2fs.static target.
+
+The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
+for extent-based files
+
+The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
+files.
+
+All source files no longer have any trailing white space.
+
+The io_channel_read_blk64() and io_channel_write_blk64() functions are
+now functions instead of C preprocessor macros to provide better
+forward compatibility.
+
+The e2fpsrogs translation template now expands the @x abbrevation.
+
+Various namespace leackages in libblkid, libe2p, and libext2fs have
+been fixed.
+
+Fix a parallel build problem in e2fsprogs.
+
+E2fsprogs is now more portable to Solaris.
+ * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
+ are always present.
+ * Scripts do not assume that /bin/true is always in /bin
+ * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
+ * Flush stdio handles before calling setbuf(), since Solaris will
+ discard any pending output to the stream.
+ * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
+ picky about which C compiler can beused for SUSv3 conformance.
+ Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
+ and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
+ Since we need some SUSv3 functions, consistently use SUSv3 so
+ that e2fsprogs will build on Solaris using c99.
+ * Solaris C99 does not support varargs C preprocessor macros
+ * Solaris header files pollute the C namespace if in/netinet.h
+ is included, which conflicts with e2fsprogs' use of the kmem_cache_t
+ typedef.
+ * Solaris ships with a pathetically ancient shell in /bin/sh so we
+ avoid the use of various more avanced shell constructs such as $().
+
+The "make rpm" command will now take some extra configure optiosn from
+the build environment without needing to patch the source tree.
+
+The ext2fs_add_dir_block() function will now grow the dblist more
+aggressively as an optimization to avoid copying the array too often.
+
+The e2fsck_write_bitmaps() will write the block and inode bitmaps
+together instead of in two passes.
+
+
+E2fsprogs 1.41 (July 10, 2008)
+==============================
+
+Add support for ext4 filesystem features, in particular extents,
+uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
+support for checking journal checksums. Debugfs will print new
+superblock and inode fields that were defined for ext4. For example,
+the nanosecond and i_version fields of an inode, and the
+s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
+Note: Resize2fs doesn't currently support the combination of flex_bg
+and !resize_inode. (Addresses Debian Bug: #388452, #425477)
+
+Tune2fs can support migrating a filesystem from using 128 byte inodes
+to 256 byte inodes, so it can take advantage of the full features of
+ext4.
+
+Add support for "undo" support. E2fsck and mke2fs can optionally
+record an undo log which can replayed by the program e2undo.
+
+E2fsck could damage a filesystem by trying to relocate inode tables
+due to corrupted block group descriptors, where the attempted inode
+table relocation would do far more harm than good. E2fsck has been
+fixed to detect this these sorts of corrupted block group descriptors
+much earlier in e2fsck processing, so it can try to use the backup
+superblock and block group descriptors first. This should be a much
+better strategy for recovering these types of corrupted filesystems.
+(Addresses Sourceforge Bug: #1840291)
+
+E2fsck will display a more understandable message when the last check
+field in the superblock is in the future. (Addresses Debian Bug:
+#446005).
+
+E2fsck now performs more extensive and careful checks of extended
+attributes stored in the inode.
+
+Enhance mke2fs to print a more explanatory error message when
+ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
+#488663)
+
+Fix mke2fs to use a default block size of 4k when formatting an
+external journal device. This is done by using a fixed filesystem
+type list that consists only of the single filesystem type "journal"
+when looking up configuration keys in /etc/mke2fs.conf. (Addresses
+Debian Bug: #488663)
+
+Speed up how mke2fs writes the journal data blocks by writing the disk
+blocks in larger chunks.
+
+Fix blkid handling of stale devices. Fix a bug which could cause a
+core dump while garbage collecting the blkid cache, and assure that
+blkid_find_dev_with_tag() never returns a non-existent device. Also,
+if a filesystem is found at a new /dev location, eliminate any
+duplicate stale entries which can not be verified.
+(Addresses Debian Bugs: #487758, #487783)
+
+Add more paranoid checks for LVM volumes and swap partitions in
+blkid's probe function, to reduce the chances of false positives.
+
+The mke2fs program now has a much more sophisticated system for
+controlling configuration parameters of a newly created filesystem
+based on a split filesystem and usage type system. The -t option to
+mke2fs was a deprecated alias to -c; it now specifies a filesystem
+type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
+separated usage list. The filesystem type information and type
+information is used to extract configuration parameters from the
+/etc/mke2fs.conf file.
+
+The mke2fs program will no longer complain and request the -f option
+when the user tries to create a filesystem with greater than 2**31
+blocks.
+
+When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
+adjust the mke2fs.conf file so filesystems for the Hurd are created
+with a blocksize of 4096 and inode size of 128, which is all it knows
+how to handle. (Addresses Debian Bug: #471977)
+
+Mke2fs will always make sure that lost+found always has at least 2
+blocks, even for filesystems with very large blocksizes (i.e., 64kb).
+
+Resize2fs will now print the minimum needed filesystem size if given
+the -P option, and will resize the filesystem to the smallest possible
+size if given the -M option.
+
+Fix resize2fs to clean up the resize_inode if all of the reserved gdt
+blocks are consumed during an off-line resize.
+
+The "ls" command in debugfs now supports the -p option, which causes
+it to quote the filenames so that spaces or tabs in directory entries
+are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
+Sourceforge Feature Request: #1201667)
+
+Fix a potential off-by-one buffer oveflow in the fs_device_name in an
+e2image file.
+
+The chattr program will return a non-zero exit code in case of
+failures, and error messages can be suppressed with the -f option.
+(Addresses Red Hat Bugzilla: #180596)
+
+Fix a bug in badblocks which caused it to overrun an array and likely
+crash if more than 8 test patterns are specified using the -t option.
+(Addresses Debian Bug: #487298)
+
+Add support to badblocks to limit how quickly it reads from the disk
+drive (so it can be used for background scrubbing), and so it will
+abort after finding a given number of errors.
+
+Remove support for the legacy big-endian filesystem format which only
+existed on extremely long-dead PowerPC kernels almost a decade ago.
+
+Remove MASIX support from e2fsprogs.
+
+Add I/O statistics reporting to e2fsck.
+
+Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
+Czech translations.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #487443, #487675, #490003)
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+(Addresses Debian Bugs: #393313, #487849, #440983, #440981)
+
+Programmer's Notes
+------------------
+
+Factor out bitmap code in preparation for adding 64-bit new-style
+bitmaps.
+
+Fix gcc -Wall warnings
+
+Fix the pkg-config files so that private librares are specified in
+"Libs.private:".
+
+Fix the libext2fs.texinfo manual so it builds with modern versions of
+texinfo.
+
+Silence the makefile from showing the awk command used to build the
+
+Clean up the badblocks group so to make it more portable and robust.
+
+Avoid using predictable filenames in /tmp in blkid's regression test
+suite. Also remove bashism's in the regression test script.
+
+If the configure script is given --with-diet-libc, don't use thread
+local storage, since diet libc doesn't support TLS. (Addresses
+Sourceforge Bug: #2000654)
+
+Fix the blkid regression test suite to tolerate older versions of
+mkswap that don't support the -U option.
+
+A few library routines have been converted to support 64-bit block
+numbers; in particular, the I/O manager functions, the test_io,
+inode_io, and unix_io managers have all be converted to support 64-bit
+operation.
+
+Debugfs can now be extended for use by test programs. See
+lib/ext2fs/extents.c for an example for how it can be used. The test
+program links against the debugfs object files, and provides
+additional commands by defining an auxiliary libss command table.
+
+The lazy_bg filesystem feature, which was only used by developer's
+testing, has been removed since it has been largely supplanted by
+uninit_bg. This also simplifies the code.
+
+
+E2fsprogs 1.40.11 (June 17, 2008)
+=================================
+
+Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
+percentage of reserved blocks. (Addresses Debian Bug: #452639)
+
+Updated Spanish and Catalan translations.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #483962, #483023)
+
+Add detection for ZFS volumes to the libblkid library.
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+(Addresses Debian Bug: #486463)
+
+Programmer's notes:
+-------------------
+
+Fix marginal C code in probe_lvm2() function to the blkid library more
+portable for older compilers.
+
+Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
+
+Fix ext2fs_swap{16,32,64} functions so they can be used by external
+applications on big-endian machines. (Addresses Debian Bug: #484879)
+
+
+E2fsprogs 1.40.10 (May 21, 2008)
+================================
+
+When deciding whether or not to revalidate a blkid cache entry, if the
+device's mtime is newer than the last time the cached entry was
+validated, force a revalidation.
+
+Fix a potential data corruption bug in e2fsck in the journal replay.
+The chances of this is happening is extremely remote, especially the
+default data=ordered or data=writeback modes. However, if a block
+which has been journalled starts with the first four bytes 0xc03b3998,
+when e2fsck replays the journal, those four bytes will be replaced
+with zero's. Fortunately, it is highly, highly unlikely for e2fsck
+metadata to begin with those fatal 4 byte sequence, and unless
+data=ordered mode is in use, data blocks are never journaled.
+
+Updated German, Dutch, Sweedish, and Vietnamese translations.
+
+Programmer's notes:
+-------------------
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details.
+
+Remove default sizes of types when cross compiling, since autoconf
+2.50 can figure this out automatically now.
+
+
+E2fsprogs 1.40.9 (April 27, 2008)
+=================================
+
SuSE's security team audited uuidd and came up with a few minor
issues. None of them are serious given that uuidd runs setuid as a
unprivileged user which has no special access other than libuuid
One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
work correctly with in-inode extended attributes.
+Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
+translations.
+
+Debugfs will avoid using a pager if the standard output is not a tty.
+
+Fix debugfs and tune2fs to correctly handle daylight savings time when
+parsing a time string.
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+
+Fix fsck completion bars when multiple filesystems were being checked
+in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
+#203323, Addresses Sourceforge Bug: #1926023)
+
+Fix fsck so that progress information is sent back correctly when
+multiple filesystems are being check and the output of fsck is being
+redirected to a file descriptor. Also, include the device name (w/o
+spaces) in the progress information sent back via a file descriptor.
+(Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
+#1926023)
+
+Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
+
+If logsave receives a SIGTERM or SIGINT signal, it will now pass that
+signal to its child process.
+
+Fix mke2fs's creation of are resize inode when there is a non-standard
+s_first_data_block setting.
+
+Fix bug in blkid when run by an unprivileged user; most devices were
+not reported correctly. 9Addresses Launchpad Bug: #220275)
+
+Mke2fs will not allow the logically incorect combination of
+resize_inode and meta_bg, which had previously caused mke2fs to create
+a corrupt fileystem.
+
+Fix fsck in German locales so that a 'j' means yes.
+(Addresses Sourceforge Bug: #1947683)
+
+
Programmer's notes:
-------------------
Fixed various Debian packaging issues --- see debian/changelog for
details.
+Update valgrind options in test_script to work with valgrind 3.2.3
+
+Update texinfo.tex to a much newer version from the FSF.
+
+Remove bashism for configure script and from the lib/ss Makefile.
+Addresses Sourceforge Bug: 1921969
+
+Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
+
+Fix build system so that if texinfo is not installed, it won't print a
+(harmless) error message.
+
+
E2fsprogs 1.40.8 (March 13, 2008)
=================================
Fix memory leak in ext2fs_write_new_inode()
Add support for using a scratch files directory to reduce e2fsck's
-emory utilization on really big filesystems. This uses the TDB
+memory utilization on really big filesystems. This uses the TDB
library. See the [scratch_files] section of the e2fsck.conf man page
