-======================================
+E2fsprogs 1.43-WIP (May 18, 2015) -- cd27af3ecb83
+=================================================
-Add support for the ext4 metadata checksum feature.
+Add support for the ext4 metadata checksum, inline data, encryption,
+and read-only features.
+
+Mke2fs will now create file systems with the metadata_csum and 64bit
+features enabled by default.
+
+Support for the very old, experimental, and never-added-to-mainline
+compression feature has been removed.
+
+Debugfs can now modify extended attributes and journal transactions.
+
+The resize2fs command can now convert file systems between 64-bit and
+32-bit mode.
+
+We now use a new e2undo file format which is much more efficient and
+faster than the old tdb-based scheme. Since it so much faster,
+e2fsck, tune2fs, debugfs, and resize2fs now also can support using
+creating an undo file.
+
+The mke2fs command can now set the error behavior when initializing
+the file system (so the administrator doesn't have to issue a separate
+tune2fs -e command).
+
+E2fsck is now much more paranoid about not freeing or corrupting
+critical metadata blocks, such as inode table blocks, even if
+corrupted indirect blocks or extent trees point at these blocks.
+
+E2fsck now prints block ranges in pass1b instead of listing all of the
+blocks exhaustively.
+
+E2fsck will try to expand the root directory if the lost+found can't
+be linked to the root directory. Also, offer to use the root
+directory if lost+found can't be created.
+
+E2fsck is now more paranoid handling corrupted extent trees as well as
+corrupted journals.
+
+E2fsck can now rebuild extent trees, either (a) to optimize them, (b)
+to recover from a corrupted extent tree, or (c) to convert
+block-mapped inodes to use extents.
+
+E2fsck now has a readahead mechanism which can significantly speed its
+performance, especially on RAID arrays.
+
+E2fsck now has a "yes to all" option which the user can give if she is
+tired of answering 'y' to a very large number of questions.
+
+E2fsck will now ignore the badblocks inode if the contents of the
+badblocks inode indicate that the portion inode table containing the
+badblocks inode is bad. (We must go deeper...)
+
+E2fsck can now correctly fix directory with holes on bigalloc file
+systems.
+
+Fixed a bug in e2fsck to avoid overrunning a buffer containing jbd2
+revoke records if the journal is corrupted.
+
+Fixed a bug in e2fsck which could cause it loop forever if a special
+inode has too many invalid block mappings.
+
+Fixed a bug in e2fsck which could cause pass1b/c/d processing to get
+confused if an attempt to allocate a block can't find any free space
+in the file system.
+
+E2fsck will no longer try to force rewrite blocks located beyond the
+file system.
+
+Fixed a bug in resize2fs which could lead to resize2fs crashing or a
+corrupted file system if the file system is almost completely full
+when trying grow a file system and we need to allocate blocks to grow
+the block group descriptors.
+
+Fixed a bug in resize2fs which could cause it to get fooled trying to
+determinthe the RAID array's stride when flex_bg is enabled.
+
+The dumpe2fs output has been improved so it is cleaner and always fits
+within 80 columns. Also added a more easily machine-parsable output
+of dumpe2fs.
+
+The mke2fs program can now pre-populate a file system from a directory
+hierarchy using the -d option.
+
+The mke2fs program now skips zeroing inode table blocks if they were
+already zeroed using the discard feature.
Check to make sure file system features which can not be supported by
HURD are not enabled if the file system is created to be
HURD-compatible.
+Added a new e2fuzz command that will fuzz an ext4 image for testing
+purposes.
+
+The debugfs logdump command can now deal with 64-bit revoke tables
+correctly. Also, "logdump -O" will print the old log contents (before
+the journal was replayed).
+
+The debugfs bmap command can now be used to set or allocate a physical
+block.
+
+Fixed a bug so "filefrag -B -e -v" does not return a separate entry
+for each block.
+
+The file I/O functions now correctly handle inodes containing
+uninitialized blocks.
+
+Fix a bug in tune2fs so that removing uninit_bg feature on a bigalloc
+file system won't result in corrupted block bitmaps.
Programmer's Notes
------------------
+Fixed coverity, sparce gcc -Wall, and clang warnings/nits.
+
+Added Android build files so that e2fsprogs can be built in the
+Android source tree.
+
Reduce the use of libc functions in libext2fs that may not be present
in the boot loader environment, at least for those functions that are
needed by boot loadsers such as yaboot.
+Developers can now overide the debugging and optimization flags by
+redefining the CFLAGS makefile macro.
+
+The mke2fs command will now ask the user for confirmation if block
+device or image file contains an existing file system image, and
+stdout and stdin are connected to a tty.
+
+The libext2fs library now picks a more intelligent goal block when
+doing block allocations.
+
+The libext2fs library will now automatically set the BLOCK_UNINT flag
+if all of the blocks in a block group are free, to speed up future
+e2fsck and dumpe2fs operations on the file system.
+
+Add two new functions ext2fs_new_range() and ext2fs_alloc_range() to
+libext2fs.
+
+The ext2fs_zero_blocks() command will use FALLOC_FL_ZERO_RANGE for
+file-based images.
+
+The ext2fs_bmap() function supports new flags BMAP_UNINIT and
+BMAP_ZERO.
+
+The ext2fs_new_block2() function will now call the alloc_block hook
+before checking fs->block_map.
+
Support for the MMP feature can now be disabled at compile time.
+Added support to manipulate extended attributes to libext2fs.
+
+Added a lot of new regression tests.
+
+Added endian annotations so it's possible to scan e2fsprogs for endian
+problems using a static code analyzer.
+
+Fixed memory leaks in libext2fs.
+
+The e2fsck jbd2 handling code has been resynced with the 3.16 kernel.
+There is now a script in the contrib directory which automates most of
+the resync process.
+
+The build system will now run cppcheck (a static code analysis tool)
+via "make C=1"
+
+
+E2fsprogs 1.42.13 (May 17, 2015)
+================================
+
+Fixed a potential buffer overflow while closing a file system in
+libext2fs. (CVE-2015-1572, Addresses Debian Bug: #778948)
+
+Fixed a bug which could cause e2fsck to corrupt Hurd file systems.
+(Addresses Debian Bug: #760275)
+
+Fixed a deadlock which occurs when using systemd and e2fsck.conf's
+logging feature. (Addresses Debian Bug: #775234)
+
+Fixed a bug which could cause programs using libext2's inode table
+scanning functions from crashing on certain corrupted file systems.
+(Addresses Debian Bug: #773795)
+
+Fixed dumpe2fs so it won't crash if the user doesn't specify a block
+device (file system). (Addresses Debian Bug: #764293)
+
+Fixed e2fsck so if it notices unexpected HTREE blocks in pass 2, it
+will report the correct directory inode containing the inconsistency.
+
+If e2fsck fails to grow the dir_info structure due realloc(3) not
+having enough memory, it will now fail with explanatory message
+instead of staggering on failing with a confusing internal error
+messages.
+
+The tune2fs program will zero out the superblock journal backup
+information when removing a journal from a file system.
+
+The mke2fs program now enables the large_file feature by default.
+
+Fixed a bug which could cause badblocks to crash if there are millions
+and millions of bad blocks.
+
+Fixed some use-after-free bug in resize2fs and e2fsck.
+
+Fixed a memory leak in tune2fs.
+
+Fixed some bigendian bugs that had crept into both indirect and extent
+handling inside libext2fs.
+
+Updated/fixed various man pages.
+
+Update Esperanto, German, and Spanish translations. Added Danish
+translation.
+
+Programmer's Notes
+------------------
+
+Fixed coverity, sparce gcc -Wall, and clang warnings/nits.
+
+Clean up some build system problems (build failures with various
+configure options, fix Posix portability issues, etc.)
+
+The functions ext2fs_inode_alloc_stats[2]() and
+ext2fs_block_alloc_stats[2]() now check the inode and block numbers
+passed to them, to avoid crashes caused by buggy callers.
+
+The libext2fs directory iterator will now check for an invalid
+directory entry length instead of possibly walking off the end of the
+directory buffer.
+
+
+E2fsprogs 1.42.12 (August 25, 2014)
+===================================
+
+Fix various e2fsck bugs when trying to repair bigalloc file systems.
+
+E2fsck can now repair a file system with an overly large
+s_first_meta_bg field, which had previously caused all e2fsprogs
+programs to crash when trying to open such a file system.
+
+Fix e2fsck so that it can correctly fix a number of rare file system
+corruptions that were discovered when using a file system fuzzer.
+
+Fix e2fsck so it does not try to write back block group descriptors if
+they have not been modified.
+
+Mke2fs program will now place metadata blocks in the last flex_bg so
+they are contiguous. This reduces free space fragmentation in a
+freshly created file system, as well as allowing mke2fs commands which
+request extremely large flex_bg size to succeed.
+
+Mke2fs now creates hugefiles more efficiently (with fewer extent tree
+blocks).
+
+Fix a 32/64-bit overflow bug that could cause resize2fs to loop
+forever. (Addresses-Launchpad-Bug: #1321958)
+
+The resize2fs program will now use much less memory when resizing very
+large file systems.
+
+Fix a bug which could cause resize2fs to get confused and produce a
+corrupted file system when shrinking a file system that had been
+previously expanded and converted to use the meta_bg file system
+format, but which no longer needs to use the meta_bg file system
+format any longer. This typically happened with large (> 16TB) file
+systems. (Addresses Debian Bug: #756922)
+
+The e4defrag program will now defrag backwards-allocated files.
+
+Fix tune2fs updating UUID's when manipulating file systems with
+external journals (both the file system and journal UUID).
+
+Fix tune2fs so it can remove an external journal for file systems with
+a 1k block size.
+
+Add a new debugfs command, "inode_dump", which prints the inode in hex
+and ASCII format.
+
+The debugfs's "set_inode_field" will now automatically allocate blocks
+for indirect blocks and extent tree blocks.
+
+Fix debugfs's "set_inode_field" so can properly handle
+"block[IND|DIND|TIND]".
+
+The debugfs "rdump" command will now take multiple source arguments.
+
+Fixed a double close(2) bug in "rdump" and "rdump -p".
+
+Fix debugfs's argument parsing for the freefrag command.
+
+Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
+(Addresses Launchpad Bug: #1356496)
+
+Clarified messages that were confusing users in debugfs, e2fsck,
+mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543,
+#757544)
+
+Dumpe2fs will now complain if extra arguments are given to it.
+(Addresses Debian Bug: #758074)
+
+Updated/fixed various man pages. (Addresses-Debian-Bug: #726760)
+
+Update Czech, Dutch, French, Polish, Spanish, Sweedish, Ukrainian, and
+Vietnamese translations.
+
+Programmer's Notes
+------------------
+
+The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the
+number of system calls issued.
+
+Fixed profiled build.
+
+The libext2fs library will now more efficiently split an extent tree
+index block when appending to an end of a file.
+
+Fixed free block accounting for 64-bit file systems.
+
+Add a new function ext2s_inode_size_set() which takes care of all of
+the required feature flag modifications.
+
+The regression tests no longer require the presence of the md5sum
+program.
+
+Fix build failure on MIPS platforms on Debian (Addresses Debian Bug:
+#754605)
+
+Fix various Coverity warnings (#1225003, #1229243, #1252003)
+
+
+E2fsprogs 1.42.11 (July 9, 2014)
+================================
+
+Add support so that mke2fs can create hugefiles so that they are
+aligned relative to the beginning of the disk, instead of relative to
+the beginning of the partition, using the mke2fs.conf configuration
+parameter "hugefiles_align_disk".
+
+Fix a bug which causes e2fsck to abort a journal replay on a file
+system with bigalloc enabled. (Addresses Debian Bug: #744953)
+
+Add sanity checks so that mke2fs will refuse insanely large flex_bg
+counts specified by the -G option. Insanely large flex_bg sizes can
+result in a file system which can't be unmounted, or with extremely
+pessimal metadata layouts.
+
+The mke2fs program will provide a better metadata layout for
+moderately large (but believable) flex_bg counts, such as 133,072.
+
+The mke2fs progam will also check the kernel version number to
+determine whether the lazy_itable_init option is supported, so that
+lazy inode table initialization can be used even if the ext4 is
+compiled as a module which isn't loaded at the time that mke2fs is
+run.
+
+Add description of ext4's mount options to the ext4 section 5 man
+page.
+
+Improve the chattr man page and clean up the chattr usage message.
+
+E2fsck will now automatically fix a last mount time or last write time
+which is in the future in preen mode, instead of aborting the fsck
+check.
+
+Mke2fs will now check the file system revision number requested by the
+command line, and reject it if it is too large. A file system with an
+unsupported revision number will not be accepted by any of the other
+file system tools, and this command line option is rarely used, so
+let's try to help the user not shoot their own foot off.
+
+The debugfs progam can now set the error count and associated
+first_error and last_error fields in the superblock using the
+set_super_value command.
+
+Resize2fs will not try to calculate the minimum size of a file system
+if it contains errors. Otherwise a very badly corrupted file system
+image can cause the minimum size calculation to loop forwever. Since
+resize2fs will not allow a file system marked as containing errors to
+be resized. It's pointless to calculate the minimum size, so just
+skip it.
+
+Fixed a typo in one of mke2fs's error message.
+
+If filefrag runs into an error, it will continue processing the rest
+of the files specified on thec ommand line, but then exit with an
+error code.
+
+Filefrag now prints some additional new flags (such as
+FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values.
+
+Fixed support in filefrag for files with > 2**32 blocks on 32-bit
+platforms.
+
+Fixed a file descriptor leak in debugfs when copying files.
+
+Fixed a regression introduced in 1.42.10 which caused mke2fs to fail
+to create file systems larger than 2GB on 32-bit platforms.
+(Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107)
+
+Add Esparanto and Ukrainian translations, and update Czech, Dutch,
+French, German, Italian, Polish, Sweedish, and Vietnamese
+translations.
+
+Fixed various compiler warnings.
+
+
+Programmer's Notes
+------------------
+
+The gcc "-checker" option has been long deprecated, so remove support
+from e2fsprogs. It was causing a few people to be confused when they
+tried enabling the configure option.
+
+Update to the latest version of the config.status and config.rpath
+files, as well as newer versions of the autoconf files in aclocal.m4.
+Also, move the e2fsprogs-specific macros to acinclude.m4, which allows
+people who want to use autoreconf to do so.
+
+Make the use of strptime() function in debugfs to be more portable to
+fix regression test failures for FreeBSD and MacOS.
+
+A few miscellaneous changes designed to make life easier for
+translators.
+
+Fix the f_quota test and some Makefile dependencies if quota support
+is not enabled.
+
+Fix cross-compilation support, which got broken in 1.42.10.
+(Addresses Debian Bug: #753375)
+
+Delete lib/ext2_types.h on a make clean, and build it as necessary.
+
+Add a debug program used for libext2fs unit tests.
+
+Clean up the tests so that it avoids using GNU-specific behaviour in
+mktemp. Make sure the temporary files are cleaned up if the tests are
+interrupted.
+
+Add a new ext2fs_close_free() helper function which automatically
+takes care of freeing the ext2_filsys structure even if ext2fs_close()
+returns an error.
+
+
+E2fsprogs 1.42.10 (May 18, 2014)
+================================
+
+Mke2fs now creates file systems in regular files (which is very often
+used when maintaining virtual machine images) without requiring the
+user to use the force option. In addition, the mke2fs output has been
+made much less verbose and only displays information that users will
+be more likely to find useful by default.
+
+Mke2fs now will ask the user to confirm that they want to continue
+before wiping out a pre-existing file system, partition table, or LVM
+physical volume.
+
+Mke2fs now has the ability to create file systems where all the
+metadata is located at the very beginning of the device. This can be
+useful for flash devices which have SLC flash at the beginning of the
+disk, for FAT compatibility, for example. As part of this, mke2fs and
+tune2fs can control the location of the data blocks used by the
+journal inode. In addition, the new sparse_super2 feature allows for
+even fewer (anywhere from zero to two) backup superblocks.
+
+Mke2fs now uses much less CPU when allocating the blocks used for very
+large file systems.
+
+Mke2fs can now support creating a file system at an offset. This can
+be useful when creating a disk image for virtual machines (Addresses
+Debian Bug: #497984)
+
+Previously, e2fsck had a number of very serious bugs when checking a
+file system wich used the new the quota file system option (where the
+quota inodes were stored in hidden inodes) and the quota inode was
+inconsistent with the actual usage data. This problem was documented
+in https://ext4.wiki.kernel.org/index.php/Quota. These problems have
+been fixed in 1.42.10, so the quota should be safe to use with
+e2fsprogs 1.42.10.
+
+Fixed in a bug in resize2fs which could cause shrink operation fail in
+the unlikely situation when the inode table needs to be moved to a
+location before the current location.
+
+Resize2fs now has a much more accurate (and less conservative)
+estimation of how far the file system can be shrunk. This allows a
+mostly empty filesystem which is a few terabytes, to be shrunk to a
+few megabytes in a single resize2fs -M operation.
+
+E2fsck will now force a full file system check if there are any file
+system inconsistencies detected in the super block.
+
+The filefrag program will now display hte shared extent flag, which is
+used by file systems such as btrfs.
+
+If the number of inodes in the file systems is larger than the time
+that file sytem was created (as measured by the number of seconds
+since January 1, 1970) e2fsck would print a scary (but otherwise
+harmless) warning of file system corruption for each inode in the
+orphan list. This false positive has been fixed.
+
+The e4defrag program has been fixed so it will no longer refuse with
+filesystem with the 64-bit or the bigalloc feature enabled.
+
+The logsave progam will print a much less scary message which could
+lead users to believe something has gone very wrong with e2fsck exits
+with a non-zero exit status (since this is normal after e2fsck has
+automatically fixed a file system corruption during a preen
+operation). (Addresses Debian Bug: #468821)
+
+When creating a file system which is larger than 16TB, the
+resize_inode option must be disabled -- since the resize_inode simply
+doesn't support reserving metadata block numbers which is larger than
+32 bits. The mke2fs program does this automatically if the file
+system size is determined automatically. It will now also do this if
+the file size is specified explicitly.
+
+Fixed bugs associated with resize2fs and shrinking bigalloc file
+systems.
+
+The e2fsck program will no longer try to add a UUID on a mounted file
+system with checksums enabled, since this could leave the file system
+checksums broken.
+
+Tune2fs will allow the removal of an external journal from file system
+which is marked as needing the journal replayed when the force ("-f")
+option is given twice. (Addresses Debian Bug: #559301)
+
+Tune2fs will no longer support enabling sparse_super if the meta_bg
+file system feature is enabled, since it could result in data loss.
+In practice, all modern file systems have sparse_super is enabled, so
+it's not worth trying to change how tune2fs handles enabling the
+sparse_super feature.
+
+Fixed support for 1k block file systems with the meta_bg feature.
+
+When the superblock is corrupt, e2fsck can't figure out the location
+of the alternate superblock. Unfortunately, the routine that
+calculates the location of the alternate superblock uses 8193 if it
+can't figure this out, so the message printed by e2fsck always
+suggests using "e2fsck -b 8193". This message has been fixed to
+suggest both the superblock location of 8193 and and 32768.
+(Addresses Debian Bug: #719185)
+
+The lookback mount detection code that was introduced in 1.42.9 wasn't
+actually compiled in due to an autoconf oops, so it's fixed now in
+1.42.10. (Addresses Debian Bug: #497984)
+
+A bug introduced in 1.42.9 would cause debugfs to print two error
+messages if it found an error while parsing a user-supplied block
+number. This has been fixed in 1.42.10.
+
+Update Czech, Dutch, French, German, Polish, Spanish, Sweedish, and
+Vietnamese translations. (Addresses Debian Bug: #703048)
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #719189,
+#719184)
+
+Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725)
+
+
+Programmer's Notes
+------------------
+
+Fixed a lot of coverity, sparce gcc -Wall, and clang warnings/nits.
+
+Allow the location of pkg-config files to be specified independent of
+the libdir location via a makefile variable.
+
+Fixed parse-types.sh not to complain when cross-compiling and the
+sizes of types are different between the target architecture and the
+architecture of the build system
+
+Allow the regression test suite to work correctly on systems which do
+not have the "truncate" or "mksawp" programs.
+
+Allow e2fsck to build correctly on systems (such as Android) that do
+not have the signal.h file.
+
+E2fsprogs now has code coverage testing which can be enbled using
+"configure --enable-gcov".
+
+The libe2p.h header file can now be used included by C++ programs.
+
+The profile/config file used by e2fsck and mke2fs will interpret
+numbers with a leading 0 character to mean that they should be
+interpreted as an octal integer.
+
+The extent handling functions in libext2fs have been improved so they
+have proper rollback when there is an error splitting an extent. Also
+fix a number of bugs when punching holes in files, and fix an
+off-by-one bug when inserting an extent into an empty inode.
+
+The libext2fs library now handles the support of BLOCK_UNINIT by
+clearing the portion of block bitmap when it is loaded, instead of
+when it is used. This reduces the chances of bugs, and and simplifies
+the code. It also means that debugfs will properly show that blocks
+in uninitialized block groups as being unused when using the testb
+command.
+
+The e4defrag program will try to use fadvise64 or posix_fadvise64() if
+it is present, which allows 64-bit offsets on 32-bit systems.
