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 ssystems.

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 libary 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 progam 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
determinthe 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, 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 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, 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.


E2fsprogs 1.42.9 (December 28, 2013)
====================================

Mke2fs will detect an attempt to create a file system on a loop
mounted file and complain without the -FF option.  Also fixed mke2fs
so it allows the creation of a file system on a mounted device with
two -F options, as documented in the man page, instead of three -F
options.

Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
libext2fs to correctly handle bigalloc and 64-bit file systems.  There
were many corner cases that had not been noticed in previous uses of
these file systems, since they are not as common.  Some of the bugs
could cause file system corruption or data loss, so users of 64-bit or
bigalloc file systems are strongly urged to upgrade to e2fsprogs
1.42.9.

The tune2fs program will now not allow changing the uuid on a mounted
file system which has the uninit_bg feature enabled.  This avoids a
nasty race where the kernel and tune2fs are both retrying rewrite the
group descriptors at the same time, with different ideas about what
the UUID should be.

When e2fsck is rehashing an extent-mapped directory, it's possible
(although very rare) that an extent block will need to be allocated;
fix e2fsck to make sure that the block gets marked as used.

Mke2fs will now properly set the LARGE_FILE feature when creating a
journal >= 2GB --- which can happen when using 64k block size.

Fixed debugfs so that its freei command will correctly handle a request
to free a range of consecutive inodes.

Fixed 2fsck so it will not erroneously complain that an external journal
is invalid if it is exactly 2**32 blocks.

Fixed e2fsck so it won't try checking for, and adding, a missing
lost+found directory when running in read-only mode.

Fixed e2image so that progress information won't get leaked to stdout.
(Addresses Red Hat Bugzilla: #1327329)

Fixed e2image to avoid some buffer overruns which would cause it to when
creating a "standard (non-raw, non-qcow2) image file.  Standard
e2image files are actually very rarely used, so we didn't notice when
the changes to enable the qcow2 format broke this e2image mode.

Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
on the resize_inode feature when the meta_bg feature is set, since
these two features can not be set at the same time.

Fixed tune2fs so that when it disables the quota feature, it updates all
of the backup superblocks.

Fixed dumpe2fs that would cause it to abort when run using an image file
when trying to print the journal information (which is not present in
an e2image created image file).

Fixed a potential integer overflow in e2reefrag.
(Addresses-Debian-Bug: #718205)

Enhance debugfs so that when copying a sparse file from a native file
system into the file system image using the "write" command, it will
create a sparse file into the destination file system.

Enhanced debugfs so it can support a command line which is up to 8k
long.

E2image will refuse (unless the -f option is specified to force the
issue) to create a raw or qcow image using a mounted file system,
unless the -f option is specified to force the issue.

E2image has been optimized for using it to efficiently copy a file
system by only copying the allocated blocks, by using the options -ra.
New options (-o and -O) have been added so that a source and
destination offset can be given.  The -p option will print progress
information so the user will know how far along the copy is going.
And finally, the new option -c is useful for updating a file system on
an SSD, by avoiding unnecessary writes.  E2image can also shift a file
system image by doing an in place move.

Fix a regression introduced in 1.42.8 which would cause e2fsck to
erroneously report uninitialized extents past the EOF (as determined by
i_size) to be invalid.

Fixed resize2fs so under a corner case when an inode has a complex
extent tree, it will not corrupt an interior node in the extent tree.

Fixed resize2fs which would sometimes corrupt a file system when
shrinking a file system to a minimum size using resize2fs -M.
(Addresses Debian Bug: #660793)

Fixed resize2fs so that it will relocate inode table blocks if this
becomes necessary when shrinking the file system.

Fixed resize2fs and e2fsck so they will not crash when hit a failure
while operating on a file system with the MMP feature enabled.

Fixed a bug in debugfs which caused it create an invalid inode when
trying to write a zero-length file.

E2fsck will no longer crash if it tries to delete an invalid
extent-mapped symlink.

E2fsck will no longer crash if it comes across an directory which is
larger than 2GB (which is not allowed in valid file systems).

Fixed debugfs's help texts to fully document all options and otherwise
be more helpful.

Updated/fixed various man pages.  (Addresses Debian Bugs: #586218,
#669730, #698076)

Fixed various Debian Packaging Issues (#698879, #721365)


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

Fix sparse, gcc -Wall and clang nits.

Update config.{guess,sub} to the latest version

Fixed various memory and file descriptor leaks on various error paths,
as well as some missing error return checks, which were found using
Coverity.

Run sparse against source files when building e2fsprogs with 'make
C=1'.  If instead C=2, it configures basic ext2 types for bitwise
checking with sparse, which can help find the (many many) spots where
conversion errors are (possibly) happening.

Allow the regression test to be run in chrooted environments where
/etc/mtab might be missing.

The ext2fs_punch() function, which was introduced in 1.42, was broken
in many ways, but this was never noticed since it wasn't used for
anything significant.  Some of the bugs include failing when trying to
punch a completely sparse file, failing when punching an extent-mapped
inode when the starting block was at the beginning of the inode, and
not being able to punch a single block (where start_blk == end_block).
It also didn't handle being passed an invalid, too-large ending block
number, and didn't handle properly terminate at the right place when
operating on an indirect-mapped inode.

Fixed some minor typo's in the error catalog for libext2fs.

Fixed ext2fs_file_set_size2() so that if it truncates an inode by
setting the file size, to zero the rest of the block to the end of the
file, so that if an ext4 FUSE driver tries to extended the file, that
we don't avoid stale data from being returned.

Fixed ext2fs_bmap() to disallow clients from trying to map or set
logical blocks which are larger than what an extent-mapped or indirect
block-mapped inode can allow.

If debugfs (or some userspace program using libext2fs) creates a file
which is larger than 2GB, make sure the large_file feature flag gets
set.

Fix a bug in ext2fs_link() where if there is multiple empty slots in the
directory which are large enough, the directory entry could get
inserted more than once in the directory.

If quota support is disabled (which is the default), make sure that
all traces of the quota support is removed from usage messages, man
pages, and tune2fs must not be able to enable the quota file system
feature.  (Addresses Red Hat Bugzilla: #1010709)

The ext2fs_file_write() now updates i_size on a successful write,
instead of only updating i_size wen the file is closed via
ext2fs_file_close().

Added a shell script, populate-extfs.sh which uses debugfs to populate
an ext2/3/4 file system image from a given directory.  It is similar
to the genext2fs program, but it supports ext3 and ext4 file system.

Add changes to the libext2fs library to support block group
descriptors larger than 64 bytes (for future compatibility).

Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
leave an extra block in the file when truncating the file down to
size.

The html version info pages are now built using makeinfo --html
instead of the unmaintained and now-obsolete texi2html program.


E2fsprogs 1.42.8 (June 20, 2013)
================================

As a part of mke2fs's option parsing cleanup, the use of the -R option
will give a warning that it is depreated (it has been so documented
since 2005) and -E should be used instead.

Mke2fs will not give warnings about the bigalloc and quota options in
quiet mode.

If an invalid journal size is given to mke2fs, it will now complain
and exit sooner.

Debugfs was erroneously giving spurious error messages for certain
extent_inode subcommands which take arguments (split_node,
replace_node, and insert_node).  This has been fixed.

Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
other programs is used by mke2fs.

Change mke2fs so that it does not set the root directory to the real
uid/gid of the mke2fs process.  Add the extended option root_owner to
override this behavior.

Fix resize2fs when shrinking file systems to make sure that bitmap
blocks aren't left outside the bounds of the shrunken file system.
This could happen with flex_bg file systems that were grown using
the old online resizing algorithm.

E2fsck will now detect and repair corrupted extent trees which contain
invalid extents at the end of the extent tree leaf block.

E2fsck will now longer complain about zero length extended attribute
values.

Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
to crash.

Add safety check so tune2fs will not attempt to set the inode size to
be larger than the block size.

Fix e2fsck so it can check a read-only root file system with an
external journal.  (Addresses Debian Bug: #707030

Fix off-line resizing of file systems with flex_bg && !resize_inode
(Addresses Debian Bug: #696746)

Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug:
#703067)

Enhance chattr to allow clearing the extent flag if the kernel allows
migrating extent based files to use indirect blocks.

Update German translation.

Updated/fixed various man pages.  (Addresses Debian Bugs: #712429,
#712430, #707609)

Fixed various Debian Packaging Issues (Addresses Debian Bug #708307)
