<P>Add support for ext4 filesystem features, in particular extents,
uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
support for checking journal checksums. Debugfs will print new
superblock and inode fields that were defined for ext4. For example,
the nanosecond and i_version fields of an inode, and the
s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
Note: Resize2fs doesn't currently support the combination of flex_bg
and !resize_inode. (Addresses Debian Bug: #388452, #425477)</P>
<P>Tune2fs can support migrating a filesystem from using 128 byte inodes
to 256 byte inodes, so it can take advantage of the full features of
ext4.</P>
<P>Add support for "undo" support. E2fsck and mke2fs can optionally
record an undo log which can replayed by the program e2undo.</P>
<P>E2fsck could damage a filesystem by trying to relocate inode tables
due to corrupted block group descriptors, where the attempted inode
table relocation would do far more harm than good. E2fsck has been
fixed to detect this these sorts of corrupted block group descriptors
much earlier in e2fsck processing, so it can try to use the backup
superblock and block group descriptors first. This should be a much
better strategy for recovering these types of corrupted filesystems.
(Addresses Sourceforge Bug: #1840291)</P>
<P>E2fsck will display a more understandable message when the last check
field in the superblock is in the future. (Addresses Debian Bug:
#446005).</P>
<P>E2fsck now performs more extensive and careful checks of extended
attributes stored in the inode.</P>
<P>Enhance mke2fs to print a more explanatory error message when
ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
#488663)</P>
<P>Fix mke2fs to use a default block size of 4k when formatting an
external journal device. This is done by using a fixed filesystem
type list that consists only of the single filesystem type "journal"
when looking up configuration keys in /etc/mke2fs.conf. (Addresses
Debian Bug: #488663)</P>
<P>Speed up how mke2fs writes the journal data blocks by writing the disk
blocks in larger chunks.</P>
<P>Fix blkid handling of stale devices. Fix a bug which could cause a
core dump while garbage collecting the blkid cache, and assure that
blkid_find_dev_with_tag() never returns a non-existent device. Also,
if a filesystem is found at a new /dev location, eliminate any
duplicate stale entries which can not be verified.
(Addresses-Debian-Bugs: #487758, #487783)</P>
<P>Add more paranoid checks for LVM volumes and swap partitions in
blkid's probe function, to reduce the chances of false positives.</P>
<P>The mke2fs program now has a much more sophisticated system for
controlling configuration parameters of a newly created filesystem
based on a split filesystem and usage type system. The -t option to
mke2fs was a deprecated alias to -c; it now specifies a filesystem
type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
separated usage list. The filesystem type information and type
information is used to extract configuration parameters from the
/etc/mke2fs.conf file.</P>
<P>The mke2fs program will no longer complain and request the -f option
when the user tries to create a filesystem with greater than 2**31
blocks.</P>
<P>When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
adjust the mke2fs.conf file so filesystems for the Hurd are created
with a blocksize of 4096 and inode size of 128, which is all it knows
how to handle. (Addresses Debian Bug: #471977)</P>
<P>Mke2fs will always make sure that lost+found always has at least 2
blocks, even for filesystems with very large blocksizes (i.e., 64kb).</P>
<P>Resize2fs will now print the minimum needed filesystem size if given
the -P option, and will resize the filesystem to the smallest possible
size if given the -M option.</P>
<P>Fix resize2fs to clean up the resize_inode if all of the reserved gdt
blocks are consumed during an off-line resize.</P>
<P>The "ls" command in debugfs now supports the -p option, which causes
it to quote the filenames so that spaces or tabs in directory entries
are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
Sourceforge Feature Request: #1201667)</P>
<P>Fix a potential off-by-one buffer oveflow in the fs_device_name in an
e2image file.</P>
<P>The chattr program will return a non-zero exit code in case of
failures, and error messages can be suppressed with the -f option.
(Addresses Red Hat Bugzilla: #180596)</P>
<P>Fix a bug in badblocks which caused it to overrun an array and likely
crash if more than 8 test patterns are specified using the -t option.
(Addresses Debian Bug: #487298)</P>
<P>Add support to badblocks to limit how quickly it reads from the disk
drive (so it can be used for background scrubbing), and so it will
abort after finding a given number of errors.</P>
<P>Remove support for the legacy big-endian filesystem format which only
existed on extremely long-dead PowerPC kernels almost a decade ago.</P>
<P>Remove MASIX support from e2fsprogs.</P>
<P>Add I/O statistics reporting to e2fsck.</P>
<P>Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
Czech translations.</P>
<P>Fixed various Debian packaging issues --- see debian/changelog for
details. (Addresses Debian Bugs: #487443, #487675, #490003)</P>
<P>Fixed spelling mistakes, typos, and otherwise clarified man pages.
(Addresses Debian Bugs: #393313, #487849, #440983, #440981)</P>
<H3>Programmer's Notes</H3>
<P>Factor out bitmap code in preparation for adding 64-bit new-style
bitmaps.</P>
<P>Fix gcc -Wall warnings</P>
<P>Fix the pkg-config files so that private librares are specified in
"Libs.private:".</P>
<P>Fix the libext2fs.texinfo manual so it builds with modern versions of
texinfo.</P>
<P>Silence the makefile from showing the awk command used to build the</P>
<P>Clean up the badblocks group so to make it more portable and robust.</P>
<P>Avoid using predictable filenames in /tmp in blkid's regression test
suite. Also remove bashism's in the regression test script.</P>
<P>If the configure script is given --with-diet-libc, don't use thread
local storage, since diet libc doesn't support TLS. (Addresses
Sourceforge Bug: #2000654)</P>
<P>Fix the blkid regression test suite to tolerate older versions of
mkswap that don't support the -U option.</P>
<P>A few library routines have been converted to support 64-bit block
numbers; in particular, the I/O manager functions, the test_io,
inode_io, and unix_io managers have all be converted to support 64-bit
operation.</P>
<P>Debugfs can now be extended for use by test programs. See
lib/ext2fs/extents.c for an example for how it can be used. The test
program links against the debugfs object files, and provides
additional commands by defining an auxiliary libss command table.</P>
<P>The lazy_bg filesystem feature, which was only used by developer's
testing, has been removed since it has been largely supplanted by
uninit_bg. This also simplifies the code.</P>
