E2fsprogs 1.43.8 (January 1, 2018)
==================================

Fix a bug where updated bitmap checks might not be written to disk.
(Addresses Debian Bug: #883869)

Some newly added fields in the superblocks were not getting byte
swapped (which were not noticed since big endian systems are amazingly
unpopular).  Fix them and compile-time checks to avoid this class of
bugs from happening in the future.  (Lustre Bug #9309)

Fix a potential use after free bug in e2fsck when fixing a corrupted
root node in directory hash tree.

Fix a bug in e2fsck where a badly/maliciously corrupted superblock
(which is not fixed due to the -n option, for example) can cause a
floating point exception when printing the summary statistics.
(Addresses Debian Bug: #879220)

Fix debugfs's ncheck command so that it correctly prints the inode
number when printing an error message.

Fix a bug in e2freefrag where it could print an incorrect free blocks
count on a file system with the 64-bit block number feature.

Update the German, Serbian, Spanish, and Ukrainian translations.

Fix a bug where resize2fs's free blocks sanity check could fail with a
false positive and refuse to check a file system with the 64-bit block
number feature.

Fix and clarify various man pages and documentations.  Also fixed up
some random usage texts that were incorrect.  (Addresses Debian Bugs:
#880483)

Fixed various Debian Packaging Issues.  (Addresses Debian Bugs: #880207,
#881408, #881590, #881591)

Programming notes
-----------------

Fix various compiler warnings.

Clean up Makefile output.

Fix compatibility problems with glibc 2.27 casued by a collision with
copy_file_range().


E2fsprogs 1.43.7 (October 16, 2017)
===================================

Fix the error handling code in debugfs, fuse2fs and tune2fs so errors
trying to replay the journal won't accidentally result in a seg fault
if reopening the file system after the journal replay fails for some
reason.

Fix resize2fs to avoid it from either failing or corrupting the file
system image in certain corner cases when doing an off-line resize.

Fix many spelling mistakes in various man pages, code comments, and
program messages.

Fix e2fsck and debugfs so that maliciously corrupted file systems will
not cause buffer overflows.  (Addresses Debian Bugs: #873757, #878104)

Update German translation.  (Addresses Debian Bug: #833514)

Fixed various Debian Packaging Issues.  (Addresses Debian Bugs:
#873812, #873813, #876551)

Programming notes
-----------------

Test descritions have been shorted to fit in 80 columns.

Fix various tests to avoid leaving temp files in /tmp.


E2fsprogs 1.43.6 (August 29, 2017)
==================================

Fix printing of quota inconsistency messages on 32-bit platforms in
e2fsck.  Also fix a bug which cause project quota problems to be
labelled as group quota problems.

Fix UI problems caused by fuzzy translations such that some messages
are in English and some are in the foreign language, and it's not
obvious to user how to answer yes/no questions.  (Addresses Debian
Bug: #856586).

Fix some out-of-bounds memory accesses in e2fsck caused by (usually
maliciously) corrupted file systems.  (Addresses Debian Bugs: #871539,
#871540)

Optimize CPU usage in e2fsck for very large, very fragmented sparse
files.

Add an optional mode in e2fsck which trades off additional memory for
CPU time when processing file systems that are heavily hard-linked.
(This can be a very large amount of memory, so this feature is
disabled for now.  How to automatically determine when it would be
helpful to enable this optimization, and when it is _safe_ to enable
this optimization is still a bit of a research problem.)

The mke2fs program will automatically upsize the inode size to 256 if
it is not explicitly specified on command-line and the default inode
size is not large enough to support the project quota feature
requested by the user.  If the inode size is explicitly specified to
be 128 bytes, and the project quota is enabled mke2fs will fail since
with an error explaining that project id's can't be supported when the
inode size is < 256 bytes.

The tune2fs program will not allow the project feature or project
quotas to be enabled in the inode size is 128 bytes.

The tune2fs program now prints a more understandable message explaining
that the file system needs to be checked using e2fsck -f before
running certain complex tune2fs operations.  (Addresses Debian Bug:
#857336)

If the proceed_delay option is enabled in /etc/e2fsck.conf, the message
indicating that user can wait N seconds to proceed was ambiguous.
That message has been made more clear.  (Addresses Debian Bug:
#857336)

Fix LFS bug which caused e2image to fail to create regular e2image
files which are larger than 2 GiB on 32-bit platforms.  (Addresses
Debian Bug: #855246)

Fix FreeBSD portability problem caused by the fact that they no longer
use block devices.  (Disks are character mode devices.)

Update the Czech, French, Polish, Swedish, and Vietnamese translations.

Fixed various Debian Packaging Issues.


Programming notes
-----------------

Avoid changing the blkid cache when running tests.  (Normally the
blkid cache is not writable by the user running tests, but...)

The tar file generation process will now create reproducible
artifacts.

Removed legacy entries for ext4dev in the default mke2fs.conf file.


E2fsprogs 1.43.5 (August 4, 2017)
=================================

Fix a bug which could cause e2fsck to loop forever when rebuilding an
encrypted directory with entries with identical prefixes up to an
embedded NUL character.

Fix build when configured with --disable-threads or --enable-profile.

Fix ext2fs_sync_device() so it returns the proper error code if the
BLKFLSBUF ioctl fails for some reason.

Fix a potential crash in tune2fs when enabling project quota when the
file system has no inodes by fixing error handling in the
quota_write_inode() in libsupport.

Fix a bug in debugfs's "ls -p" handling which could cause it to print
garbage after a file name in a directory entry.

Fix a number of bugs in debugfs, dumpe2fs, e2fsck, tune2fs, and
resize2fs where a carefully/maliciously corrupted file systems (found
by American Fuzzy Lop) could these programs to crash or hang.
(Addresses Debian Bug #868489)

E2fsck no longer issues some harmless bitmap warnings caused by a
corrupted file system; since those corruptions will be fixed up by
e2fsck later, there's no point issuing these internal warnings.

E2fsck will now notice invalid quota inode numbers, and offer to fix
them.

Fix a regression introduced in e2fsprogs 1.43 which broke mke2fs's
hugefile creation so that they aren't contiguous.  (Addresses Google
Bugs 62791459 and 638037607)

Fix how backup superblocks are written in big endian systems so they
are all correctly byte swapped.

Fixed tune2fs's support for enabling and disabling project quota.

The badblock program now properly handles languages which have
multi-column wide character such as Chinese.  (Addresses Debian Bug:
#860926)

The mke2fs -U option now accepts "null", "clear", "random", or "time"
just as tune2fs's -U option.

Fix e2fsck's -E bmap2extent feature (which converts a file to use
extents from indirect block maps) so that it handles sparse files correctly.

Fix libext2fs to correctly handle accounting for an external xattr
block on bigalloc file systems.

Fix e2fsck to correctly handle quota accounting when deleting files
that have multiply-claimed blocks pass 1b.

Fix potential buffer overrun bug in e2fsck when using 128 byte inodes.
(Addresses Google Bug 37326362).

E2fsck's extent tree optimization can now be disabled via an
command-line extended option or via an e2fsck.conf configuration
parameter.

The e2fsck program now properly updates the quota accounting when
optimizing the extent tree.  (Addresses Google Bug 36391645)

Fix some error handling in e4crypt when operating on keyring ID's.

Fix e2fsck's quota handling when the bigalloc feature is enabled.

The libext2fs file system now uses readahead when opening file systems
to speed up opening very large file systems with the meta_bg option.

If e2fsck logging is enabled, e2fsck will report the exit code in the
last line of the log file.

Debugfs can now open file systems with a bad superblock checksum, and
the show_super_stats command will print the expected checksum.

Fix a regression introduced in e2fsprogs 1.43.4 where tune2fs was not
able to correctly enable the quota feature.  (Addresses Debian Bug
#855417)

E2fsck will only return an exit status code of 1 if it has fixed a
file system corruption.  If it only performed an optimal optimization
of internal file system metadata, it will now return 0.

Fix e2fsck so it won't check inode fields of deleted inodes.  This was
mostly harmless, but the addition of a check in 1.43.4 to enforce the
requirement that inline data inodes have a system.data attribute
caused a regression in xfstests generic/079.  Fix this and a number of
other checks which could lead to false positive reports of file system
corruption.

Removed a debugging printf in libsupport which could result to some
extraneous and confusing output if the user specifies a quota type.

The debugfs logdump command now accepts a new -S option which will
cause it to print information about the journal superblock.

Added a missing space in debugfs's ls -l output to separate the size
and date fields.

Update the Czech, Danish, Dutch, French, Hungarian, Polish, Serbian,
Spanish, Swedish, Ukrainian, and Vietnamese translations.

Update various man pages.  (Addresses Debian Bugs #867895 and #865584)

Fix various compiler and UBSAN warnings.

Fixed various Debian Packaging Issues.  (Addresses Debian Bugs
#864144 and #866623)


Programming notes
-----------------

The blkid library can now recognize exfat file systems.

Add new test, j_recover_csum3_64bit, which checks to make sure we
correctly recovering 64-bit journals using the v3 checksum format.

Fix portability assumption in tests; don't depend on the existence of
/dev/stdin.

Fix portability with newer versions of glibc and with Cygwin builds on
Windows 8 and Windows 10.

Clean up the comments in problem.c match the message that will
actually be printed.

Removed an unused an obsolete header file.



E2fsprogs 1.43.4 (January 31, 2017)
===================================

Fix e2fsck to require that the system.data extended attribute is
always present even for files smaller than 60 bytes, to be consistent
with the kernel.

Fix a bug which was causing mke2fs -d and fuse2fs to improperly handle
Posix ACL's.

Fix a bug which could cause mke2fs -d to fail if there is an
zero-length file in source directory tree.

Clarify the default for the "proceed?" question printed by mke2fs and
tune2fs.  (Addresses Debian Bug: #852727)

Debugfs will now display project quota information.

Debugfs's do_set_xattr now uses C strings to parse extended attribute
values, and will print the extended attributes using either C strings
or hex bytes when using debugfs's do_get_xattr command.  It will now
allow developers to see the contents of the system.data extended
attribute.

Fix a bug in mke2fs where I/O errors weren't getting properly reported
to the user.

Fix multiblock writes in the unaligned Direct I/O fallback code.
(Which is rarely needed on Linux systems, but which is required on
Freebsd systems.)

Make sure the default mke2fs.conf file includes the uninit_bg feature
flag.  (Which was accidentally dropped in v1.43).

Fix a bug in resize2fs when operating on very large file systems which
have a block size different from the VM page size.

If the reported device size is absurdly large, mke2fs will now report
an error instead looping forever or crashing.

Fix various Coverity warnings and other memory leaks in fuse2fs and
extended attribute manipulation functions.

Replace a test file but which had a "non-commercial use-only"
copyright permission file with a newer version from the Cyrus imapd
package which now has a 4-clause BSD license, which was making some
lawyers nervous, even though the test file in question was only used
in lib/et's regression testing and was never included in any compiled
binary.  (Addresses Debian Bug: #840733)

Stop installing mkfs.ext4dev and fsck.ext4dev

Update Chinese, Czech, Polish, Serbian, and Spanish translations and
add the Finnish and Malay translation.  (Addresses-Debian-Bug: #774379)

Update various man pages (Addresses-Debian-Bug: #852726)

Programming notes
-----------------

Fix more FreeBSD-11 compatibility bugs, including some unmasked by
FreeBSD 11-rc2.

Fix the Mac build.

Fix build failure on RHEL 5.x systems caused by an old version of
libmagic.

Fix a number of bugs reported by ASAN that can cause some (mostly
harmless) memory dereferences beyond allocated memory.


E2fsprogs 1.43.3 (September 4, 2016)
====================================

Fix e2fsck's handling of timestamps on 32-bit systems.

E2fsck will now check, and if necessary repair the extra isize fields
in the inode and superblock.

Fix crashes on architectures such as sparc64 that are sensitive to
unaligned pointer dereferences in the journal recovery code when
journal checksums are enabled.

Programming notes
-----------------

Support reproducible builds by not capturing the build directory into
the mk_cmds and compile_et scripts.  Also fix debian build rules to
ensure build reproducibility.

Fix debian build rules to ensure build reproducibility and to avoid
hiding the linker flags for e2fsck.static so the build hardening log
scanner can properly audit the build.

Fix compatibility with FreeBSD's pmake and teach the configure script
to force the creation of pmake-compatible Makefiles if the
FORCE_NATIVE_MAKE environment variable is set to a non-empty value.


E2fsprogs 1.43.2 (September 1, 2016)
====================================

Fix resize2fs so it will not crash if there is an extended attribute
block but it doesn't need to migrate any blocks during an off-line
resize

Fix a crash when mke2fs or debugfs tries to copy in a directory
hierarchy containing an empty directory

Mke2fs will now use a larger journal by default for filesystems
greater than 128 GB.  (1GB instead of 128 MB.)

Fix an alignment bug in e2fsck which caused sparc64 architectures to
crash when replaying the journal on file systems with a 64-bit block
number.

Clarify the message printed by tune2fs message when the user needs to
run e2fsck so it's clear that the -f flag to e2fsck is needed to
force a full e2fsck scan.  (Addresses Debian Bug: #828022)

Fix a bug in e2fsck caused by a power failure during e2fsck's journal
replay could leave the file system in a state where if the file system
is mounted without doing a full e2fsck scan, the file system could get
corrupted

Fix the logic in e2fsck which decides when to repair legacy negative
timestamp encodings.

Add a command to debugfs to copy the inode structure from one inode to
another.

Fix a typo in debugfs's stat command when printing out the dtime field
on file systems with an extended timestamp.

Fix big endian bugs in the e2undo program.  (Addresses Red Hat Bug
#1344636)

Debugfs's logdump can now properly handle journals larger than 2GB.

Avoid installing the man page for fuse2fs if it has not been built.

Update the Catalan, Chinese, Danish, Dutch, French, German, Polish,
Swedish, Ukrainian translations and added new translations for
Hungarian and Serbian.


Programming notes
-----------------

Fix portability problems in fuse2fs.  Previously it wouldn't build on
systems with older glibc versions where clock_gettime() is only
available in the librt library, and if libintl is not bundled into the
C library.

Remove complicated logic which caused a static code analyzer to flag a
false positive.  (A static code analyzer also found a valid bug in
deciding when to repair a legacy negative timestamp encoding, so
eliminating false positives is important.)

Fixed a bug where the ext2fs library cloud provoke when a
extfs2_zero_blocks() is used (via fallocation, initializing a file
system, uninitialized uninitialized inode table blocks) after a
different file system which also used ext2fs_zero_blocks().

Enable the unix_io manager in the ext2fs library so it can accept the
use of a file descriptor.  This is helpful in cases where the file
descriptor comes from temporary file created using O_TMPFILE, or
passed in from a unix domain socket.

Fix a Windows64 portability bug.


E2fsprogs 1.43.1 (June 8, 2016)
===============================

Fixed e2fsck so that it would correctly update the project quota usage
when deleting a corrupted and inode, and fixed mke2fs so it wouldn't
dereference memory beyond the small inode structure (which was wrong,
but worked mostly by accident unless hardening or some security malloc
was in use).

Fixed a large number of FreeBSD portability problems.  (To build on
FreeBSD, however, we still need to use GNU Make and redirect dd to use
GNU dd.)

The configure script now supports --enable-hardening, which enables
stack protection, fortify, read-only relocation tables, immediate
dynamic symbol binding, and text segment ASLR (if the kernel has
userspace ASLR support enabled) by enabling position independent
executable code.  (Distributions who want to do their own special
thing can set CFLAGS, CFLAGS_SHLIB, CLFAGS_STLIB, LDFLAGS,
LDFLAGS_SHLIB and LDFLAGS_STATIC as appropriate.)

The configure script now supports --disable-tdb since on 64-bit
systems, it's much faster to just enable additional swap space.  The
scratch_files feature in e2fsck.conf is mostly only useful on 32-bit
systems.

Fixed the Direct I/O fallback codepath in the Unix I/O manager so that
read/modify/write worked correctly.  Fortunately in practice (with the
exception of the Undo handler when running on FreeBSD) used this buggy
codepath. so file systems weren't getting corrupted.

Mke2fs will now warn if the user provides a label which is too long.
(Addresses Debian Bug: #791630)

Debugfs's rdump command now works correctly when dumping the root
directory of a file system.  (Addresses Debian Bug: #766125)

Fixed a bug in debugfs so it would correctly calculate a block group's
checksum field field on 64-bit systems.

E2fsck now has a much more understandable error message when the
journal superblock is corrupt and the user declines to fix it.
(Addresses Debian Bug: #768162)

Fixed support of extended timestamps on 64-bit systems.

Updated/fixed various man pages.  (Addresses Debian Bugs: #766379,
#761144, #770750, #428361, #766127)

Fixed various Debian Packaging Issues.  (Addresses Debian Bug: #825868)


Programming notes
-----------------

Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.

Fixed Android build makefiles (which was missing a newly added file in
lib/support).

In general, checks on s_creator_os have been removed in favor of
feature flag specific checks; if there is something that can't be
checked via the presence of a feature flag, we will simply check
whether the creator OS is *not* EXT2_OS_HURD which is the one
operating system where there has been extensive abuse of the
s_creator_os flag.

The libmagic library has been suppressed when running the regression
test suite to avoid false test failures caused by differences between
versions of libmagic (and/or the magic number database).

The tests/test_script program now accepts the --failed option, which
will run those tests that had previously failed.

Fixed tests build on those systems which require LDFLAGS to be set.

Fixed the regression test suite so it will properly filter out version
numbers with two components (such as 1.43) from log files before
comparing them with the expected golden output.


E2fsprogs 1.43 (May 17, 2016)
=============================

Add support for the ext4 metadata checksum, checksum seed, inline
data, encryption, project quota, and read-only features.

Support for the very old, experimental, and never-added-to-mainline
compression feature has been removed.

Mke2fs will now create file systems with the metadata_csum and 64bit
features enabled by default.

The mke2fs program will now support multiple -O options (instead of
just ignoring all but the last -O option).

Mke2fs will now correctly determine the size of a file system and
handle the discard operation correctly when the "-E offset=NNN" is
used.  (Addresses Debian Bug: #803629)

The tune2fs program will ask the user for confirmation before starting
dangerous operations if the terminal is available, and it will replay
the journal if necessary.

Add an ext2/3/4 FUSE server

Debugfs can now modify extended attributes and journal transactions.

Debugfs now can properly display and set extended timestamps.

E2fsck will offer to fix extended timestamps that were incorrectly
encoded by older kernels.

Fix miscellaneous MMP bugs in debugfs.

Fix sparse_super2 bugs in mke2fs and resize2fs.

Fix or improve offset support in mke2fs, e2undo, and libext2fs.

The resize2fs command can now convert file systems between 64-bit and
32-bit mode.

Fix potential out-of-bounds memory access in resize2fs when doing a
large off-line file system grow operation.

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).

Teach mke2fs to parse a human-readable argument for -i option.

Teach mke2fs to automatically handle creating file systems > 500T by
automatically enable the meta_bg feature.

Mke2fs will now prompt for user verification before rewriting a file
system's superblock using the -S option.

Mke2fs no longer complains if the user tries to create a file system
using the entire block device (e.g., without using a partition).  The
minor number convention is not used by all block devices, and it's
quite normal in some circumstances to create a file system on /dev/sdc
instead of /dev/sdc1.

Fix an "mke2fs -d" bug which could create inodes with invalid
extended attribute blocks

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.

E2fsck will now check for extent mapped inodes with no extent header
and clear them if found.

E2fsck now checks to make sure the extended attribute header doesn't
result in the xattr extending beyond the bounds of the inode

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.

The e2fsck program will no longer update the quota inodes when it is
interrupted.

Fix a bug which in rare cases would cause e2fsck -fD to corrupt an
extent-mapped directory.

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
determine the RAID array's stride when flex_bg is enabled.

Fix resize2fs bug that could leave block allocation bitmaps
uninitialized.

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 filefrag program now accounts for holes in sparse files created by
the file punch operation as an expected/optimal mapping.

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.

Updated/fixed various man pages.  (Addresses Debian Bug: #798425)


Programmer's Notes
------------------

Fixed coverity, sparse, 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 loaders such as yaboot.

Developers can now override the debugging and optimization flags by
redefining the CFLAGS makefile macro.

The libext2fs library now has support for fallocate.

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, sparse, 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, Swedish, 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 program 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 program 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 forever.  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 the command 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.
