-E2fsprogs 1.41.8-WIP (July 7, 2009) commit: 4bd87f22
+E2fsprogs 1.42.8 (June 20, 2013)
+================================
+
+As a part of mke2fs's option parsing cleanup, the use of the -R option
+will give a warning that it is depreated (it has been so documented
+since 2005) and -E should be used instead.
+
+Mke2fs will not give warnings about the bigalloc and quota options in
+quiet mode.
+
+If an invalid journal size is given to mke2fs, it will now complain
+and exit sooner.
+
+Debugfs was erroneously giving spurious error messages for certain
+extent_inode subcommands which take arguments (split_node,
+replace_node, and insert_node). This has been fixed.
+
+Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
+other programs is used by mke2fs.
+
+Change mke2fs so that it does not set the root directory to the real
+uid/gid of the mke2fs process. Add the extended option root_owner to
+override this behavior.
+
+Fix resize2fs when shrinking file systems to make sure that bitmap
+blocks aren't left outside the bounds of the shrunken file system.
+This could happen with flex_bg file systems that were grown using
+the old online resizing algorithm.
+
+E2fsck will now detect and repair corrupted extent trees which contain
+invalid extents at the end of the extent tree leaf block.
+
+E2fsck will now longer complain about zero length extended attribute
+values.
+
+Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
+to crash.
+
+Add safety check so tune2fs will not attempt to set the inode size to
+be larger than the block size.
+
+Fix e2fsck so it can check a read-only root file system with an
+external journal. (Addresses Debian Bug: #707030
+
+Fix off-line resizing of file systems with flex_bg && !resize_inode
+(Addresses Debian Bug: #696746)
+
+Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug:
+#703067)
+
+Enhance chattr to allow clearing the extent flag if the kernel allows
+migrating extent based files to use indirect blocks.
+
+Update German translation.
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #712429,
+#712430, #707609)
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #708307)
+
+Programmer's Notes
+------------------
+
+Use secure_getenv() in preference to __secure_getenv().
+
+Optimize CPU utilization of ext2fs_bg_has_super().
+
+Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
+SEEK_CUR is used with large files.
+
+The ext2fs_read_inode_full() function will no longer use
+fs->read_inode() if the caller has requested more than the base 128
+byte inode structure and the inode size is greater than 128 bytes.
+
+Fix build failure with --enable-jbd-debug.
+
+Clean up filtering of outputs for the regression tests by using a
+common sed script.
+
+Fix gcc -Wall and clang nits.
+
+
+E2fsprogs 1.42.7 (January 21, 2013)
+===================================
+
+Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
+quota features are still under development. For more information
+please see:
+ * https://ext4.wiki.kernel.org/index.php/Bigalloc
+ * https://ext4.wiki.kernel.org/index.php/Quota
+
+Add some new options to filefrag from Lustre's patches to e2fsprogs:
+ * add -k option to print extents in kB-sized units (like df -k)
+ * add -b {blocksize} to print extents in blocksize units
+ * add -e option to print extent format, even when FIBMAP is used
+ * add -X option to print extents in hexadecimal format
+
+Fix resize2fs so that it can handle off-line resizes of file systems
+with the flex_bg feature but without a resize_inode (or if we run out
+of reserved gdt blocks). This also fixes a problem where if the user
+creates a filesystem with a restricted number of reserved gdt blocks,
+an off-line resize which grows the file system could potentially
+result in file system corruption.
+
+Fix a resize2fs bug which could cause it to corrupt bigalloc file
+systems when doing an off-line resize.
+
+Further optimize resize2fs so it doesn't use quite as much CPU when
+resizing very large file systems.
+
+Fixed 32-bit overflow bugs which could cause resize2fs to fail and
+possibly corrupt the file system while resizing 64-bit file systems.
+
+Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
+mke2fs crash due to a divide-by-zero if the 64bit file system feature
+is enabled.
+
+Add better error checking to mke2fs to check for invalid parameters
+when creating bigalloc file system.
+
+When creating bigalloc filesystems, the -g option to mke2fs will now
+specify the number of clusters per block group.
+
+Add to debugfs the functionality to corrupt a specific file system
+block via the "zap_block" command.
+
+Add to debugfs the functionality to print out a hex dump of a block in
+the file system via the "block_dump" command.
+
+Add to debugfs the functionality to manipulate the extent tree
+directly via the "extent_open" command.
+
+Fixed debugfs's mknod command so that it updates the block group
+statistics.
+
+Fix e2fsck so it can detect and fix inconsistencies in the interior
+nodes of an inode's extent tree.
+
+Fix a potential memory corruption failure in e2fsck's error path if
+the call to ext2fs_open2() fails.
+
+Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
+resulting file name for the log file is longer than 100 bytes, that it
+properly handles this situation instead of crashing.
+
+E2fsck will now report the amount of memory that it attempted to
+allocate when a memory allocation request fails, to make it easier to
+track down the problem.
+
+Fix mke2fs's handling of the mmp_update_interval option. (Addresses
+Lustre Bug: LU-1888)
+
+E2image can now include all data blocks in the e2image output file
+when the user specifies the -a option.
+
+If e2fsprogs is compiled without --enable-quota, make sure that
+tune2fs can not turn on the feature for new-style quota support, since
+afterwards, none of the e2fsprogs tools will be willing to touch that
+file system.
+
+Optimize e2fsck's so that it uses much less CPU for large file
+systems. This can result in significant speedups, especially on
+CPU-constrained systems. This was primarily done by optimizing
+libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
+
+Fix debugfs's htree command so that all its messages are sent through
+the pager.
+
+Fixed debugfs's "dump_file" and "cat" functions work correctly
+on file systems whose block size is greater than 8k.
+
+Fix e2freefrag so it works on 64-bit file systems, and so it uses much
+less memory. (Addresses Google Bug: 7269948)
+
+Update the spd_readdir.c file in the contrib directory to include some
+additions which were made in 2008 that didn't get folded into the
+version which we checked into the e2fsprogs source tree. These
+enhancements include thread safety, support for readdir64_r(), and
+safe_getenv() support in case spd_readdir.so is used for setuid binaries.
+
+Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
+translations
+
+Add a command to debugfs to create symlinks.
+
+Document the bigalloc feature in the mke2fs man page. (Addresses
+Debian Bug: #669730)
+
+
+Programmer's Notes
+------------------
+
+Fix gcc -Wall nits.
+
+Fix a spelling typo in the libext2fs texinfo documentation.
+
+Change the output from "make check" so that tools such as emacs's "M-x
+compile" does not mistake the output as containing a compiler error.
+
+Export two new functions from libext2fs: ext2fs_extent_node_split()
+and ext2fs_extent_goto2().
+
+The ext2fs_extents_fix_parents() was fixed so it does not modify the
+location of the extent handle if its current location is at an
+interior node, rather than a leaf node of an inode's extent tree.
+
+Add a regression test to assure that e2fsck can correctly fix an
+inconsistent interior node in an inode's extent tree.
+
+The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
+correctly support bigalloc file systems which use store block usage
+information in units of clusters.
+
+Fixed the help text in the configure script for --enable-quota.
+
+The m68k-specific bitops code has been removed since they were
+incorrectly treating bit numbers with the high bit set as signed
+integers. Furthermore, modern compilers do a good enough job
+optimizing the generic code there is no point in having the m68k
+specific asm statements.
+
+Fixed how we link the test programs so they always use the static
+libraries, so that we test using the libraries which we have just
+built.
+
+Update config.guess and config.sub to the latest versions from the GNU
+project.
+
+Fixed the com_err.texinfo file so that it can produce a valid
+postscript/pdf printed output.
+
+Add a regression test which checks debugfs's ability to create
+symlinks, named FIFO's, and device nodes.
+
+Add a function ext2fs_symlink(), which creates symlinks to the
+libext2fs library.
+
+Add debugging code so we can test old kernel interfaces for online
+resize to resize2fs. This backwards compatibility checking is keyed
+off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
+test the functionality of the kernel's older resize ioctls without
+needing to install an old version of resize2fs, and to also test a
+modern resize2fs's ability to work with older kernels without having
+to install an older version of the kernel.
+
+
+E2fsprogs 1.42.6 (September 21, 2012)
+=====================================
+
+When mke2fs creates file systems with lazy itable initialization, the
+progress updates for writing the inode table happens so quickly that
+on a serial console, the time to write the progress updates can be the
+bottleneck. So mke2fs will now only update its progress indicators
+once a second.
+
+Resize2fs will skip initializing the inode tables if the kernel
+supports lazy_itable_init, which speeds up growing off-line growth of
+uninit_bg file systems significantly. Resize2fs will now also
+correctly set the itable_unused field in the block group descriptor to
+speed up the first e2fsck after the file system is grown.
+
+Resize2fs has been fixed so that on-line resizing of meta_bg file
+systems work correctly. This is needed to grow file system which are
+larger than 16T.
+
+Resize2fs will now correctly handle resizing file systems to 16TB on
+32-bit file systems when "16TB" is specified on the command line.
+
+Fix mke2fs so that it will be careful to set the reserved blocks ratio
+larger than 50%; this can happen when creating small file systems and
+when the last block group is dropped because there are not enough
+blocks to support the metadata blocks in the last block group.
+
+Fixed spelling mistake in debugfs's help message.
+
+Fixed a potential seg fault in e2fsck when there is an I/O error while
+reading the superblock.
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
+
+Updated/fixed various man pages. (Addresses Sourceforge Bug:
+#3559210)
+
+Programmer's Notes
+------------------
+
+The configure option --enable-relative-symlink was broken so that it
+needed to be --enable-symlink-relative-symlinks. We will support both
+for at least two years, but then the worng configure option will be
+removed.
+
+Fixed a regression introduced in 1.42.5 so the link order for
+e2fsprogs' libraries will be correct for both static and shared
+linking. (Addresses Sourceforge Bug: #3554345)
+
+Add support for e2fsprogs to be compiled using clang/LLVM.
+
+Fix portability problems on non-Linux systems: avoid compile failures
+on systems that don't have malloc.h
+
+Fix f_mmp regression test suite so that debugfs gets killed if the
+test is interrupted.
+
+
+
+E2fsprogs 1.42.5 (July 29, 2012)
+================================
+
+Fixed a bug with mke2fs where if there is only 8 inodes per block
+group, the calculation of the number of uninitialized inodes in the
+first block group would go negative. This resulted in "mke2fs -N 256
+-t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
+would run out of space. (Addresses Sourceforge Bug: #3528892)
+
+Fixed a bug in how e2fsck would uniquify directory entry names.
+(AddressesSourceforge Bug: #3540545)
+
+Previously, e2fsck would only allow a mounted file system to be
+checked if it was the root file system and it was mounted read-only.
+Now it will allow any file system mounted read-only to be checked if
+the -f option is specified. This makes it easier to test how e2fsck
+handles checking file systems which are mounted without having to test
+on the root file system.
+
+Fixed a problem if e2fsck where if the root file system is mounted
+read-only, e2fsck would not clear an error indication in the journal
+superblock. Combined with a kernel bug, this would cause the e2fsck
+to check the file system after every single boot.
+
+The e4defrag program can now handle device symlinks, such as
+/dev/mapper/testvg-testlv, instead of insisting on a less
+human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
+#707209)
+
+Fixed filefrag so it will not crash with a segfault on files from a
+virtual file system such as /proc. (e.g., "filefrag
+/proc/partitions")
+
+Fixed filefrag so that it correctly reports the number of extents.
+(Addresses Red Hat Bugzilla: #840848)
+
+Fixed a file descriptor leak in logsave which could cause it to hang.
+(Addresses Debian Bug: #682592)
+
+Fixed e2fsck so that the file system is marked as containing an error
+if the user chooses not to fix the quota usage information.
+
+Fixed tune2fs so that it correctly removes the quota feature when the
+last quota inode is removed.
+
+Fix tune2fs so that after removing a quota inode, the block bitmap is
+updated; otherwise, e2fsck would complain after running 'tune2fs -O
+^quota <dev>'.
+
+Fix tune2fs so that when converting a file system from using legacy
+quota files to the new quota file system feature with hidden quota
+files, the accounting for these files is handled correctly so that
+e2fsck doesn't complain.
+
+Improved e2fsck's verbose reporting statistics, and allow the more
+verbose reporting to be enabled via /etc/e2fsck.conf.
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
+
+
+Programmer's Notes
+------------------
+
+Fixed portability problems on other operating systems (e.g., Hurd and
+FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
+
+Make sure that shared libraries link with the shared libraries built
+in the build tree, instead of the system provided libraries.
+Previously, libraries and executables were linked with the system
+libraries if present, and possibly using static archives instead of
+shared libraries. This was also problematic since if libext2fs.so is
+linked with a static libcom_err.a from system, the build system would
+attempt to link without -lpthread. (Addresses Sourceforge Bug:
+#3542572)
+
+
+E2fsprogs 1.42.4 (June 12, 2012)
+================================
+
+Fixed more 64-bit block number bugs (which could end up corrupting
+file systems!) in e2fsck, debugfs, and libext2fs.
+
+Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
+not properly propagating the journal's s_errno field to the superblock
+field; it was not checking this field if the journal had already been
+replayed, and if the journal *was* being replayed, the "error bit"
+wasn't getting flushed out to disk.
+
+Fixed a false positive complaint by e2fsck if all of the extents in
+the last extent tree block are uninitalized and located after the end
+of the file as defined by i_size.
+
+The dumpe2fs will now display the journal's s_errno field if it is
+non-zero, and it will also display the journal's 64-bit feature flag
+if present.
+
+Fix e2fsck so that it always opens the device file in exclusive mode
+when it might need to modify the file system, and never if the -n
+option is specified. (Previously, there were a few corner cases where
+it might get things wrong in either direction.)
+
+E2fsck now correctly truncates or deallocates extent-mapped inodes on
+the orphan list. The root cause was a bug in libext2fs's block
+iterator which could end up skipping an extent when the last block in
+an extent is removed, causing the current extent to be removed from
+the extent tree.
+
+E2fsck now correctly sets the global free block and inode counts when
+truncating or removing inodes on the orphan list in preen mode.
+Previously, it would leave these values would be set incorrectly,
+which is largely a cosmetic issue since the kernel no longer pays
+attention to those fields, but it can cause spurious complaints in
+subsequent e2fsck runs.
+
+Fix i_blocks accounting when the libext2fs library needs to add or
+remove an extent tree block on bigalloc file systems.
+
+The lsattr and chattr programs now support the No_COW flag for the
+benefit of btrfs.
+
+Debugfs now interprets date strings of the form @ddd as ddd seconds
+after the beginning of the epoch. This is handy when setting an inode
+number into the d_time field when debugging orphan list handling.
+
+Fix a precedence bug with built-in quota support which might result in
+e2fsck paying attention to the quota inode field even if the built-in
+quota feature flag is not set. Fortunately, in practice that
+superblock field should be zero for non-built-in quota file systems,
+so it's unlikely this bug would have caused problems.
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
+#674694)
+
+Programmer's Notes
+------------------
+
+The regression test suite can now run the integration tests in the
+tests directory in parallel, via "make -jN check".
+
+Add new test, f_zero_extent_length which tests e2fsck's handling of
+the case where all of the extents in the last extent tree block are
+uninitialized extents after i_size.
+
+Add a new test, f_jnl_errno, which checks handling of an error
+indication set in the journal superblock.
+
+Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
+of a 64-bit journal.
+
+Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
+tests e2fsck's handling of orphan inodes in preen mode, and truncation
+of extent inodes on the orphan list.
+
+Fixed more OS X portability issues.
+
+
+E2fsprogs 1.42.3 (May 14, 2012)
+===============================
+
+Fix a bug in the Unix I/O manager which could cause corruption of file
+systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
+(i.e., when unsigned long is 32-bits). Also fix a bug which caused
+dumpe2fs to incorrectly display block numbers > 32-bits.
+
+Improve the support for integrated quota files (where quota is a first
+class supported feature using hidden files in the ext4 file system).
+Previously the quota file was getting rewritten even when it was not
+necessary, and e2fsck would erroneously try to hide quota files which
+were already hidden.
+
+Quiet complaints in e2fsck when the total free blocks or inodes are
+incorrect in the superblock after an system crash, since we don't
+update nor depend on the superblock summaries at each commit boundary.
+
+Fixed a regression introduced in 1.42.2 which would cause applications
+outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
+would were still using the legacy 32-bit bitmaps) to crash. This was
+due to missing 32-bit compat code in side the function
+ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
+#808421)
+
+Fix a bug which would cause mke2fs to fail creating the journal if
+/etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
+#3509398)
+
+Updated/fixed various man pages.
+
+Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
+translations
+
+Fixed various Debian Packaging issues.
+
+
+Programmer's Notes
+------------------
+
+Change the nonsensically wrong types in the function signature of the
+inline function ext2fs_find_first_zero_block_bitmap2(). This was
+caused by a cut and paste error; fortunately no code in e2fsprogs used
+this inline function, and there are any users of this functions
+outside of e2fsprogs.
+
+Add support for systems which have valloc(), but which do have
+posix_memalign() nor memalign() (such as MacOS 10.5).
+
+Refactor and clean up the allocation of aligned buffers for Direct I/O
+support. Previously some allocations were requesting a greater
+alignment factor that what was strictly necessary. Also optimize
+reading and writing bitmaps using Direct I/O when the size of the
+bitmap did not fully cover the file system blocksize.
+
+Reserve the codepoints for the INCOMPAT features LARGEDATA and
+INLINEDATA.
+
+Improved the regression test suite by adding some new integration
+tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
+jbd2 format, as well as f_eofblocks which tests the new handling of
+uninitialized and initialized blocks beyond i_size. Also add a new
+unit test which verifies 32-bit bitmaps support and the new
+find_first_zero primitives.
+
+Add a few dependencies to fix parallel (make -j) builds.
+
+Removed bash'isms which were breaking the regression test suite on
+systems where /bin/sh is not bash.
+
+The config.guess and config.sub have been updated to the 2012-02-10
+version.
+
+Fix a portability problem caused by assuming the present of mntent.h
+means that setmntent() exists. Instead, explicitly test for this in
+the configure script.
+
+If the sys/signal.h header file does not exist, don't try to include
+it, since it's not available on all systems.
+
+Add support for systems that do not support getpwuid_r()
+
+The configure script now supports a new option,
+--enable-relative-symlinks, which will install relative symlinks for
+the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
+
+When building BSD shared libraries make sure the LDFLAGS variable is
+passed to the linker. Fixing this allows, for example, e2fsprogs to
+be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
+#3517272)
+
+Fix gcc -Wall nitpicks
+
+
+E2fsprogs 1.42.2 (March 27, 2012)
+=================================
+
+The resize2fs program uses much less CPU and is much faster for very
+large file systems. (Addresses Debian Bug: #663237)
+
+The seti and freei commands in debugfs can now take an optional length
+argument to set and clear a contiguous range of inodes.
+
+E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
+plan to remove support for it from the kernel file system driver. It
+really wasn't very useful and was causing more problems than it
+solves. Since e2fsck will complain if inodes that should have
+EOFBLOCKS_FL do not have the flag set, we are going to remove this
+check from e2fsprogs first, and then only remove the flag from the
+kernel much later.
+
+The mke2fs program can now use direct I/O via "mke2fs -D". This will
+slow down the mke2fs, but it makes it more polite on a loaded server
+by limiting the amount of memory that gets dirtied by mke2fs when it
+is using buffered I/O.
+
+E2fsck was needlessly closing and re-opening the file system as a side
+effect of adding Multiple Mount Protection (MMP). This isn't
+necessary for non-MMP file systems, so drop it.
+
+Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
+can more easily diagnose memory allocation failures caused by
+insufficient memory. E2fsck will now abort if there are memory
+allocation failures when the file system is initially opened and
+during the block group descriptor checks. (Addresses Google Bug:
+#6208183)
+
+If there are incorrect block group checks, e2fsck will now report the
+incorrect and corrected checksum values.
+
+The e2fsck progam can now write log files containing the details of
+the problems that were found and fixed directly, via configuration
+parameters in /etc/e2fsck.conf.
+
+Added the ability to limit the number of messages reported by e2fsck
+for a given problem type. This avoids a potential bottleneck if there
+is a serial console which can cause a boot sequence to take a long
+time if e2fsck needs to report many, many file system errors.
+
+The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
+them to use much less memory for large file systems.
+
+The dumpe2fs program will now print the expected block group checksum
+if it is incorrect. This helps to diagnose problems caused by
+incorrect block group checksums.
+
+E2fsck now checks for extents with a zero length, since the kernel
+will oops if it comes accross such a corrupted data structure. (See
+https://bugzilla.kernel.org/show_bug.cgi?id=42859)
+
+E2fsck has a number of bugs relating to discard that have been fixed.
+(1) Fixed a bug which could cause e2fsck to discard portions of the
+inode table which were actually in use. (2) E2fsck will now avoid
+using discard if the block device doesn't zero data on discard, since
+otherwise this could cause problems if the file system gets corrupted
+in the future. (3) E2fsck will now avoid using discard when it is run
+in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
+discards in the last block group.
+
+E2fsck's CPU utilization in pass 5 has been optimized, which will
+speed up e2fsck slightly.
+
+E2image will now skip copying uninitialized bitmap and inode table
+blocks.
+
+Fixed mke2fs -S so it does not corrupt the first block group's
+information.
+
+E2fsck will now check the new sysfs interface to determine if we are
+using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
+
+Updated/fixed various man pages. (Addresses Debian Bug: #665427)
+
+Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
+
+Programmer's Notes
+------------------
+
+Fixed various portability issues for non-Linux systems, particularly
+MacOS X, as well as Linux systems running with the just-released glibc
+2.15.
+
+Fix file descriptor leak in ext2fs_close() if the file system with
+uninit_bg is opened read/only with a backup superblock. (Addresses
+SourceForge Bug: #3444351)
+
+Fixed an invalid return in a non-void function in the quota code.
+(Addresses SourceForge Bug: #3468423)
+
+Fixed the debian rules file so that the calls to dpkg-buildflags works
+when the shell is dash.
+
+The debian package build now uses V=1 so that there is more
+information about potential build failures in debian buildd logs.
+
+If the uninit flags get cleared by functions such as
+ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
+superblock is marked dirty and the block group descriptor checksum is
+updated if necessary.
+
+The debian rules file will now try to load debian/rules.custom of it
+exists. This flie can skip various builds for speed reasons if there
+is no need for the e2fsck-static or udeb packages. Available
+customizations in the rules file includes SKIP_STATIC=yes,
+SKIP_BF=yes, and SKIP_DIETLIBC=yes.
+
+In addition, if the file misc/mke2fs.conf.custom.in exists in the
+source tree, it will be used instead of the standard misc.conf file in
+the upstream sources. This makes it easier for Debian-derived systems
+to distribute a custom mke2fs.conf file without having to worry about
+merge issues if future versions of e2fsprogs makes changes in the
+upstream default version of mke2fs.conf.
+
+
+E2fsprogs 1.42.1 (February 17, 2012)
===================================
+The mke2fs and e2fsck now use significantly less memory when creating
+or checking very large file systems. This was enabled by adding
+extent-based bitmaps which are stored using a red-block tree, since
+block and inode allocations tend to be contiguous.
+
+The command mke2fs -S is used as a last ditch recovery command to
+write new superblock and block group descriptors, but _not_ to destroy
+the inode table in hopes of recovering from a badly corrupted file
+system. So if the uninit_bg feature is enabled, mke2fs -S will now
+set the unused inodes count field to zero. Otherwise, e2fsck -fy
+after using mke2fs -S would leave the file system completely empty.
+
+Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
+honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
+installed an mke2fs binary using that name.
+
+The usage and help messages for the -G, -t and -T options in mke2fs
+have been fixed.
+
+If e2fsck needs to use the backup group descriptors, the
+ext2fs_open2() function clears the UNINIT bits to ensure all of the
+inodes in the file systems get scanned. However, the code which reset
+the UNINIT flags did not also recalculate the checksum, which produced
+many spurious (and scary) e2fsck messages. This has been fixed by
+resetting cheksums when the UNINIT bits are cleared.
+
+Relax a check in e2fsck which required that the block bitmap to be
+initialized when the inode bitmap is in use. This will allow us to
+eventually eliminate code from the kernel which forcibly initialized
+the block bitmap when the inode bitmap is first used, requiring an
+extra journal credit and disk write. (Addresses Google Bug: #5944440)
+
+Make sure rdebugfs (which may be installed setuid or setgid disk) does
+not honor environment variables if euid != uid or egid != gid.
+
+Debugfs's ncheck command has been optimized and now is much more
+robust with faced with corrupted file systems. The ncheck command
+also now has a -c option which will verify the file type information
+in the directory entry to see if matches the inode's mode bits. This
+is extremely useful when trying to use debugsfs to determine which
+parts of the file system metadata can be trusted.
+
+E2image will try to use ftruncate64() to set the i_size for raw
+images, instead of writing a single null byte. This avoid allocating
+an extra block to the raw image, for those file systems and/or
+operating systems that support this. (Linux does.) In addition, fix
+a logic bug that caused the file to not be properly extended if the
+size of the last hole was exactly an multiple of a megabyte.
+
+Fixed a bug in resize2fs where for 1k and 2k file systems, where
+s_first_data_block is non-zero, this wasn't taken into account when
+calculate the minimum file system size for use with the -M option.
+
+Fixed the badblocks program to honor the -s flag when in read-only -t
+mode. (Addresses Debian Bug #646629)
+
+Update Czech, Dutch, French, Polish, and Sweedish translation from the
+Translation Project.
+
+Fixed various Debian Packaging issues so that dpkg-buildflags is used
+if present, which allows e2fsprogs to be built with security hardening
+flags. (Addresses Debian Bugs: #654457)
+
+Programmer's Notes
+------------------
+
+Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
+This was only an issue for programs compiled against e2fsprogs 1.41
+that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
+#3451486)
+
+The libext2fs library now uses sysconf() to fetch the page size, instead
+of the deprecated getpagesize().
+
+The ext2fs_get_pathname() function will return a partial path if an a
+directory in the path is not a directory, displaying it as an inode
+number in angle brackets instead of giving up and displaying an error.
+This is much more helpful when a user is trying to debug a corrupted
+file system.
+
+Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
+
+Added a new library function, ext2fs_file_get_inode_num(), for use by
+fuse2fs.
+
+Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
+file, it actually works.
+
+The block iterator now properly honors the BLOCK_ABORT flag for
+extent-based flags. Previously, it didn't, which generally made code
+be less efficient, but it could cause bugs in ext2fs_link(), for
+example, by causing it to insert multiple directory entries.
+
+Fixed an (harmless other than causing a compiler warning) use of an
+uninitialized variable in e2fsck's MMP code.
+
+
+E2fsprogs 1.42 (November 29, 2011)
+==================================
+
+This release of e2fsprogs has support for file systems > 16TB. Online
+resize requires kernel support which will hopefully be in Linux
+version 3.2. Offline support is not yet available for > 16TB file
+systems, but will be coming.
+
+This release of e2fsprogs has support for clustered allocation. This
+reduces the number of block (now cluster) bitmaps by allocating and
+deallocating space in contiguous power-of-2 collections of blocks,
+which are called clustered. This is a file system level feature,
+called 'bigalloc', which must be enabled when the file system is
+initially formatted. It is not backwards compatible with older
+kernels.
+
+Added support for the Multi-Mount Protection (MMP) feature.
+
+E2fsck more efficiently uses scratch files for really big file
+systems. (This is a feature that has to be turned on explicitly; see
+[scratch_files] in the e2fsck.conf man page.)
+
+Fix a bug in e2fsck where if the free blocks and inodes counts are
+incorrect, e2fsck would fix them without printing an error message.
+This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
+any explanation of what was fixed.
+
+E2fsck will no longer attempt to clone an extended attribute block in
+pass1b handling if the file system does not support extended
+attributes.
+
+E2fsck will be more careful accidentally asking the user to continue
+if the file system is mounted, so that an escape sequence won't cause
+a false positive. (Addresses Debian Bug: #619859)
+
+E2fsck now uses less cpu time in pass 5 when large portions of the
+bitmaps are uninitialized.
+
+E2fsck will no longer segault when a corrupted file system has a bad
+extent, and removing it leads to a block needing to be deallocated.
+(Addresses SourceForge Bug: #2971800)
+
+E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
+and print debugging information to make it easier to find potential
+problems.
+
+E2fsck will check to see if the bad block inode looks insane, and will
+skip trying to use if it certain fields which should be zero look
+non-zero. This is to avoid a corrupted bad block inode causing e2fsck
+to get confused and do more harm than good.
+
+If e2fsck modifies certain superblock fields which the kernel doesn't
+look at, it will now mark the superblock as dirty without marking the
+file system as changed. This avoids signalling the init scripts that
+a reboot is necessary, since the kernel isn't going to look at those
+fields, so it won't care if they have been changed.
+
+Fixed a bug in the libext2fs library (in the binary search routine of
+the icount abstraction) that could (very, very rarely) cause e2fsck to
+die in the middle of pass 1 or pass 2 processing.
+
+E2fsck will not try to do a discard operation if the -n option was
+specified on the command line.
+
+E2fsck now supports an extended "discard" option which will cause
+e2fsck to attempt discard all unused blocks after a full, successful
+file system check.
+
+E2fsck will check for the bad block inode to make sure it looks sane
+before trusting it, to avoid causing more harm than good to the file
+system.
+
+E2fsck now returns additional status bits in its exit code if it
+aborts early in the e2fsck run.
+
+E2fsck now correctly calculates the maximum file size in the case of
+the huge_file file system feature enabled without extents.
+
+The mke2fs and e2fsck programs now tries to use the punch hole command
+as a "discard" when operating on normal files.
+
+The e2image program now supports the qcow2 format, which is a more
+efficient way of capturing file system dumps.
+
+Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
+per-device defaults to be specified in the configuration file.
+
+Mke2fs now supports the reserved_ratio relation in the [defaults] and
+[fs_types] section in mke2fs.conf.
+
+Mke2fs now creates extent-mapped directories for the root and
+lost+found directories.
+
+Mke2fs will skip zero'ing the journal if the extended option
+"lazy_journal_init" is specified. This can save a lot of time, but it
+does add a small amount of risk if the system crashes before the
+journal is overwritten entirely once. It is epsecially useful for
+testing.
+
+Mke2fs will now create file systems that enable user namespace
+extended attributes and with time- and mount count-based file
+system checks disabled.
+
+Mke2fs will not set a stride or strip size of one block based on block
+device attributes obtained from sysfs.
+
+Mke2fs now displays a progress report during the discard process.
+
+Mke2fs now handles extreme file system parameters correctly which
+previously caused the inodes per group to drop below 8, leading to a
+segfault. (The inodes per group must be a multiple of 8, but the code
+didn't correctly deal with an inodes per group count less than 8.)
+
+Mke2fs and tune2fs previously would give an error if the user tried
+setting the stride and stripe-width parameters to zero; but this is
+necessary to disable the stride and stripe-width settings. So allow
+setting these superblock fields to zero. (Addresses Google Bug:
+#4988557)
+
+Mke2fs now gives a warning if the auto-detected block size exceeds the
+system's page size.
+
+If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
+is the default), mke2fs will now set the s_max_mnt_count superblock
+field to -1, instead of 0. Kernels older then 3.0 will print a
+spurious message on each mount then they see a s_max_mnt_count set to
+0, which will annoy users. (Addresses Debian Bug: #632637)
+
+The default mke2fs.conf now has entries for "big" and "huge", which
+are needed for very big file systems.
+
+The resize2fs program now has support for a new online resize ioctl
+that can support file systems > 16TB, once it arrives in v3.x kernels.
+
+Fixed bug which caused resize2fs to fail when shrinking an empty file
+system down to its minimal size. (Addresses Sourceforge Bug #3404051)
+
+Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
+
+Allow tune2fs to remove external journals if the device can not be
+found.
+
+Debugfs's icheck will now correctly find inodes which use the
+searched-for block as an extended attribute block.
+
+Debugfs now has a new "punch" command which remove blocks from the
+middle of an inode.
+
+Debugfs now has a new "e2freefrag" command which analyzes the free
+space fragmentation of the file system, using the same code as the
+e2freefrag program.
+
+Debugfs now has a "filefrag" command which displays information about
+a file's fragmentation.
+
+Add support to build a metadata-only, read-only, stripped-down version
+of debugfs called rdebugfs.
+
+Fixed a potential stack overrun bug in debugfs.
+
+The badblocks program now correctly recovers from I/O errors when
+direct I/O is being used. The badblocks command now also supports a
+-B option which forces the use of buffered I/O, and the -v option will
+provide a more detailed breakdown of read, write, and failed
+comparison errors.
+
+Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
+
+Added support for journals larger than 2GB.
+
+Support using both hard links and symlinks when installing e2fsprogs.
+
+Add overflow checking to tune2fs -i's fsck interval, which must fit in
+a 32-bit field.
+
+The debugfs command now has a new 'blocks' command which prints out
+data blocks of a particular inode in a format which is useful for
+scripting.
+
+Filefrag will report 0 extents correctly in verbose mode. (Addresses
+RedHat Bugzilla: #653234)
+
+Filefrag has been fixed so its -v report prints the correct expected
+block number (previously there had been an off-by-one error). In
+addition, it will now display the number of contiguous extents when -v
+is not specified. This makes it consistent with the number of extents
+printed when the -v option was specified. In addition, the number of
+contiguous extents is far more interesting/useful than the number of
+physical extents for very large files. (Addresses Debian Bug:
+#631498, #644792)
+
+Logsave's usage message has been fixed. (Addresses Debian Bug:
+#619788)
+
+Avoid an infinite loop in ext2fs_find_block_device() if there are
+symlink loops in /dev caused by a buggy udev.
+
+Added a useful "fallocate" program to the contrib directory.
+
+Fixed an ABI compatibility problem in libext2fs which broke the dump
+program. Also added back some macros which dump needed so it could
+compile against the latest version of ext2_fs.h (Addresses Debian Bug:
+#636418)
+
+Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
+Debian Bug: #641667)
+
+Added internationalization support for libcom_err error table strings.
+
+Fixed various spelling mistakes found in various output strings found
+by I18N translators.
+
+Update translations: French, Chinese, Germany, Indonesian, Swedish,
+Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
+#620659)
+
+Fixed various Debian Packaging issues. (Addresses Debian Bugs:
+#614662, #632169, #641838, #627535, #629355)
+
+Updated/clarified man pages. (Addresses Debian Bugs: #639411,
+#642193, #634883)
+
+Programmer's Notes
+------------------
+
+Initial support for quota as an integrated feature, where the quota
+files are hidden system files that are automatically maintained by
+e2fsck is present, although disabled by default. It must be enabled
+by using the configure option --enable-quota.
+
+Reserved the on-disk fields for the metadata checksum and snapshot
+features, which are currently in development.
+
+The ext2fs library now has the new functions ext2fs_punch(),
+ext2fs_get_memzero() and ext2fs_file_get_inode().
+
+The ext2fs library now has support for calculating the crc32c checksum
+(via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
+
+The I/O manager now supports the discard operation.
+
+Reserved file system code points for new 1st class quota feature.
+
+Shortened the compilation lines by moving the autoconf defines to
+a config.h header file.
+
+Fixed a potential free of an unitialized pointer in
+ext2fs_update_bb_inode().
+
+Fixed miscellaneous gcc -Wall and coverity warnings.
+
+Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
+
+Fixed a build failure when OMIT_COM_ERR is defined.
+
+Improved error checking and fixed memory leaks caused by error return
+paths.
+
+Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
+the fsync() to be skipped.
+
+Added a test for extent-mapped journals by mke2fs and tune2fs.
+
+Added a test for creating a large (over 4GB) journal using mke2fs.
+
+Added a test to make sure the inode size remains constant.
+
+The regression test script now prints the list of which tests failed.
+
+The regression test system now uses /tmp for its scratch files, which
+is often a tmpfs mounted file system and hence much faster.
+
+The i_e2image test was fixed so it works with valgrind.
+
+Tests that rely on debugfs are now skipped if debugfs wasn't built.
+
+Fixed the dependencies for "make check" so all required dependencies
+are built before running the gression tests.
+
+A link to com_err.h is installed in $(includedir) during a "make install".
+
+The po/*.gmo files are automatically rebuilt if they are missing or
+out of date. This helps out Debian packaging.
+
+Allow ext2fs_get_memalign() to compile on systems that don't have
+posix_memalign().
+
+Fixed a namespace leak in libext2fs (tdb_null).
+
+
+E2fsprogs 1.41.14 (December 22, 2010)
+=====================================
+
+Fix spurious complaint in mke2fs where it would complain if the file
+system type "default" is not defined in mke2fs.conf.
+
+The resize2fs program will no longer clear the resize_inode feature
+when the number reserved group descriptor blocks reaches zero. This
+allows for subsequent shrinks of the file system to work cleanly for
+flex_bg file systems.
+
+The resize2fs program now handles devices which are exactly 16T;
+previously it would give an error saying that the file system was too
+big.
+
+E2fsck (and the libext2fs library) will not use the extended rec_len
+encoding for file systems whose block size is less than 64k, for
+consistency with the kernel.
+
+Programming notes
+-----------------
+
+E2fsprogs 1.41.13 would not compile on big-endian systems. This has
+been fixed. (Addresses Sourceforge Bug: #3138115)
+
+The ext2fs_block_iterator2() function passed an incorrect ref_offset
+to its callback function in the case of sparse files. (Addresses
+Sourceforge Bug: #3081087)
+
+Fix some type-punning warnings generated by newer versions of gcc.
+
+
+E2fsprogs 1.41.13 (December 13, 2010)
+=====================================
+
+E2fsck now supports the extended option "-E journal_only", which
+causes it to only do a journal replay. This is useful for scripts
+that want to first replay the journal and then check to see if it
+contains errors.
+
+E2fsck will now support UUID= and LABEL= specifiers for the -j option
+(which specifies where to find the external journal). (Addresses
+Debian Bug #559315)
+
+E2fsck now has support for the problems/<problem code>/force_no
+configuration option in e2fsck.conf, which forces a problem to not be
+fixed.
+
+Dumpe2fs will now avoid printing large negative offsets for the bitmap
+blocks and instead print a message which is a bit more helpful for
+flex_bg file systems.
+
+Mke2fs will now check the file system type (specified with the -t
+option) to make sure it is defined in the mke2fs.conf file; if it is
+not, it will print an error and abort. If the usage type (specified
+with the -T option) is not defined in mke2fs.conf, mke2fs will print a
+warning but will continue. (Addresses Debian Bug #594609)
+
+Clarified error message from resize2fs clarifying that on-line
+shrinking is not supported at all. (Addresses Debian Bug #599786)
+
+Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
+displayed. (Addresses Debian Bug #555456)
+
+E2fsck will open the external journal in exclusive mode, to prevent
+the journal from getting truncated while it is in use due to a user
+accidentally trying to run e2fsck on a snapshotted file system volume.
+(Addresses Debian Bug #587531)
+
+Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
+flag.
+
+The tune2fs program can now set the uninit_bg feature without
+requiring an fsck.
+
+The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
+default mount options settings which were added in 2.6.35.
+
+The e2fsck and dumpe2fs programs now support the new ext4 superblock
+fields which track where and when the first and most recent file
+system errors occurred. These fields are displayed by dumpe2fs and
+cleared by e2fsck. These new superblock fields were added in 2.6.36.
+
+Debugfs now uses a more concicse format for listing extents in its
+stat command. This format also includes the interior extent tree
+blocks, which previously was missing from stat's output for
+extent-based files.
+
+Debugfs has a new option, -D, which will request Direct I/O access of
+the file system.
+
+Mke2fs will skip initializing the inode table if a device supports
+discard and the discard operation will result in zero'ed blocks.
+
+Badblocks will now correctly backspace over UTF-8 characters when
+displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
+Debian Bugs #583782 and #587834)
+
+E2freefrag will now display the total number of free extents.
+
+Resize2fs -P no longer requires a freshly checked filesystem before
+printing the minimum resize size.
+
+Fixed a floating point precision error in a binary tree search routine
+that can lead to seg fault in e2fsck and resize2fs.
+
+Fixed a bug in e2fsck where if both the original and backup superblock
+are invalid in some way, e2fsck will fail going back to the original
+superblock because it didn't close the backup superblock first, and
+the exclusive open prevented the file system from being reopened.
+
+Fixed a big in e2freefrag which caused getopt parsing to fail on
+architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
+
+Clarified an mke2fs error message so a missed common in an -E option
+(i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
+results in a more understandable explanation to the user.
+
+Mke2fs now displays the correct valid inode ratio range when
+complaining about an invalid inode ratio specified by the user.
+
+Mke2fs now understands the extended option "discard" and "nodiscard",
+and the older option -K is deprecated. The default of whether
+discards are enabled by default can be controled by the mke2fs.conf
+file.
+
+Mke2fs's handling of logical and physical sector sizes has been
+improved to reflect the fact that there will be some SSD's with 8k and
+16k physical sectors arriving soon. Mke2fs will no longer force block
+size to be the physical sector size, since there will be devices where
+the physical sector size is larger than the system's page size, and
+hence larger than the maximal supported block size. In addition, if
+the minimal and optimal io size are not exported by the device, and
+the physical sector size is larger than the block size, the physical
+sector size will be used to set the Raid I/O optimization hints in the
+superblock.
+
+E2fsck will now display a better, more specific error message when the
+user enters a typo'ed device name, instead of blathering on about
+alternate superblocks.
+
+Fixed various Debian Packaging Issues
+
+Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
+#589345, #591083; Addresses Launchpad Bug: #505719)
+
+Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
+Polish, Swedish, and Vietnamese translations.
+
+
+Programmer's Notes
+------------------
+
+Fix a dependency definition for the static and profiled blkid
+libraries which could cause compile failures in some configurations.
+(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.
+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
Fix filefrag program for files that have more than 144 extents.
-Update French, Polish, Czech, and Sweedish translation from the
-Translation Project.
+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.
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)
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
for more details.
