E2fsprogs 1.41.14 (December 22, 2010)
|
|
=====================================
|
|
|
|
Fix spurious complaint in mke2fs where it would complain if the file
|
|
system type "default" is not defined in mke2fs.conf.
|
|
|
|
The resize2fs program will no longer clear the resize_inode feature
|
|
when the number reserved group descriptor blocks reaches zero. This
|
|
allows for subsequent shrinks of the file system to work cleanly for
|
|
flex_bg file systems.
|
|
|
|
The resize2fs program now handles devices which are exactly 16T;
|
|
previously it would give an error saying that the file system was too
|
|
big.
|
|
|
|
E2fsck (and the libext2fs library) will not use the extended rec_len
|
|
encoding for file systems whose block size is less than 64k, for
|
|
consistency with the kernel.
|
|
|
|
Programming notes
|
|
-----------------
|
|
|
|
E2fsprogs 1.41.13 would not compile on big-endian systems. This has
|
|
been fixed. (Addresses Sourceforge Bug: #3138115)
|
|
|
|
The ext2fs_block_iterator2() function passed an incorrect ref_offset
|
|
to its callback function in the case of sparse files. (Addresses
|
|
Sourceforge Bug: #3081087)
|
|
|
|
Fix some type-punning warnings generated by newer versions of gcc.
|
|
|
|
|
|
E2fsprogs 1.41.13 (December 13, 2010)
|
|
=====================================
|
|
|
|
E2fsck now supports the extended option "-E journal_only", which
|
|
causes it to only do a journal replay. This is useful for scripts
|
|
that want to first replay the journal and then check to see if it
|
|
contains errors.
|
|
|
|
E2fsck will now support UUID= and LABEL= specifiers for the -j option
|
|
(which specifies where to find the external journal). (Addresses
|
|
Debian Bug #559315)
|
|
|
|
E2fsck now has support for the problems/<problem code>/force_no
|
|
configuration option in e2fsck.conf, which forces a problem to not be
|
|
fixed.
|
|
|
|
Dumpe2fs will now avoid printing large negative offsets for the bitmap
|
|
blocks and instead print a message which is a bit more helpful for
|
|
flex_bg file systems.
|
|
|
|
Mke2fs will now check the file system type (specified with the -t
|
|
option) to make sure it is defined in the mke2fs.conf file; if it is
|
|
not, it will print an error and abort. If the usage type (specified
|
|
with the -T option) is not defined in mke2fs.conf, mke2fs will print a
|
|
warning but will continue. (Addresses Debian Bug #594609)
|
|
|
|
Clarified error message from resize2fs clarifying that on-line
|
|
shrinking is not supported at all. (Addresses Debian Bug #599786)
|
|
|
|
Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
|
|
displayed. (Addresses Debian Bug #555456)
|
|
|
|
E2fsck will open the external journal in exclusive mode, to prevent
|
|
the journal from getting truncated while it is in use due to a user
|
|
accidentally trying to run e2fsck on a snapshotted file system volume.
|
|
(Addresses Debian Bug #587531)
|
|
|
|
Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
|
|
flag.
|
|
|
|
The tune2fs program can now set the uninit_bg feature without
|
|
requiring an fsck.
|
|
|
|
The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
|
|
default mount options settings which were added in 2.6.35.
|
|
|
|
The e2fsck and dumpe2fs programs now support the new ext4 superblock
|
|
fields which track where and when the first and most recent file
|
|
system errors occurred. These fields are displayed by dumpe2fs and
|
|
cleared by e2fsck. These new superblock fields were added in 2.6.36.
|
|
|
|
Debugfs now uses a more concise format for listing extents in its
|
|
stat command. This format also includes the interior extent tree
|
|
blocks, which previously was missing from stat's output for
|
|
extent-based files.
|
|
|
|
Debugfs has a new option, -D, which will request Direct I/O access of
|
|
the file system.
|
|
|
|
Mke2fs will skip initializing the inode table if a device supports
|
|
discard and the discard operation will result in zero'ed blocks.
|
|
|
|
Badblocks will now correctly backspace over UTF-8 characters when
|
|
displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
|
|
Debian Bugs #583782 and #587834)
|
|
|
|
E2freefrag will now display the total number of free extents.
|
|
|
|
Resize2fs -P no longer requires a freshly checked filesystem before
|
|
printing the minimum resize size.
|
|
|
|
Fixed a floating point precision error in a binary tree search routine
|
|
that can lead to seg fault in e2fsck and resize2fs.
|
|
|
|
Fixed a bug in e2fsck where if both the original and backup superblock
|
|
are invalid in some way, e2fsck will fail going back to the original
|
|
superblock because it didn't close the backup superblock first, and
|
|
the exclusive open prevented the file system from being reopened.
|
|
|
|
Fixed a big in e2freefrag which caused getopt parsing to fail on
|
|
architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
|
|
|
|
Clarified an mke2fs error message so a missed common in an -E option
|
|
(i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
|
|
results in a more understandable explanation to the user.
|
|
|
|
Mke2fs now displays the correct valid inode ratio range when
|
|
complaining about an invalid inode ratio specified by the user.
|
|
|
|
Mke2fs now understands the extended option "discard" and "nodiscard",
|
|
and the older option -K is deprecated. The default of whether
|
|
discards are enabled by default can be controlled by the mke2fs.conf
|
|
file.
|
|
|
|
Mke2fs's handling of logical and physical sector sizes has been
|
|
improved to reflect the fact that there will be some SSD's with 8k and
|
|
16k physical sectors arriving soon. Mke2fs will no longer force block
|
|
size to be the physical sector size, since there will be devices where
|
|
the physical sector size is larger than the system's page size, and
|
|
hence larger than the maximal supported block size. In addition, if
|
|
the minimal and optimal io size are not exported by the device, and
|
|
the physical sector size is larger than the block size, the physical
|
|
sector size will be used to set the Raid I/O optimization hints in the
|
|
superblock.
|
|
|
|
E2fsck will now display a better, more specific error message when the
|
|
user enters a typo'ed device name, instead of blathering on about
|
|
alternate superblocks.
|
|
|
|
Fixed various Debian Packaging Issues
|
|
|
|
Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
|
|
#589345, #591083; Addresses Launchpad Bug: #505719)
|
|
|
|
Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
|
|
Polish, Swedish, and Vietnamese translations.
|
|
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
Fix a dependency definition for the static and profiled blkid
|
|
libraries which could cause compile failures in some configurations.
|
|
(Addresses Debian Bug: #604629)
|
|
|
|
Add support for Direct I/O in the Unix I/O access layer.
|
|
|
|
Fixed a memory leak in the Unix I/O layer when changing block sizes.
|
|
|
|
Fixed minor memory leaks in mke2fs.
|
|
|
|
Added a new function to the ext2fs library, ext2fs_get_memalign().
|
|
|
|
The tst_super_size test program will check to make sure the superblock
|
|
fields are correctly aligned and will print them out so they can be
|
|
manually checked for correctness.
|
|
|
|
Fixed some makefile dependencies for test programs in lib/ext2fs.
|
|
|
|
Reserved the feature flags and superblock fields needed for the Next3
|
|
snapshot feature.
|
|
|
|
Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
|
|
EXT4_INCOMPAT_EA_INODE.
|
|
|
|
|
|
E2fsprogs 1.41.12 (May 17, 2010)
|
|
================================
|
|
|
|
Mke2fs now gives a correct error message if the external journal
|
|
device is not found. (Addresses Red Hat Bug #572935)
|
|
|
|
Resize2fs -P will now refuse to print a minimum size if the file
|
|
system is not clean. Previously it would go ahead and print a minimum
|
|
size anyway, which might not be correct, leading to user confusion.
|
|
|
|
E2fsck now tests for extents that begin at physical block 0 and
|
|
rejects them as invalid. (Addresses Google Bug: #2573806)
|
|
|
|
Fixed a bug in e2fsck which could cause it to crash when trying to
|
|
remove an invalid extent and the block bitmaps hadn't yet been loaded.
|
|
(Addresses SourceForge Bug: #2971800)
|
|
|
|
E2fsck now will completely skip time-based checks if the system clock
|
|
looks insane or the option broken_system_clock is set in
|
|
/etc/e2fsck.conf.
|
|
|
|
E2fsck would previously report an i_blocks corruption for a 4T file
|
|
created using posix_fallocate; this bug has been fixed.
|
|
|
|
E2fsck will now correctly mark a sparse journal as invalid and will
|
|
delete and recreate the journal to address the problem.
|
|
|
|
E2fsck would previously incorrectly ask the user whether she would
|
|
like to abort the file system check after finding a problem --- and
|
|
then abort regardless of the user's answer. This is annoying, and
|
|
has been fixed.
|
|
|
|
E2fsck can now continue even if it fails to recreate the resize
|
|
inode; previously it would just abort the file system check
|
|
altogether.
|
|
|
|
E2fsck could potentially remove directory entries for inodes found in
|
|
the unused region of the inode table; this would generally happen on
|
|
ext4 file systems that do not use journalling. This bug has been fixed
|
|
by not clearing these directory entries once it has been established
|
|
that bg_unused_inodes may not be trustworthy; once pass #2 has been
|
|
completed, e2fsck will restart the file system check from the
|
|
beginning, and then it will be safe to delete any directory entries
|
|
pointing to inodes that appear to be deleted. (Addresses Google Bug:
|
|
#2642165)
|
|
|
|
E2fsck will not try to set the block group checksums if the user
|
|
cancels the fsck with a control-C. It's a bad idea to set the
|
|
checksums if e2fsck hasn't been completed, and it often results an the
|
|
error message, "Inode bitmap not loaded while setting block group
|
|
checksum info". (Addresses Launchpad Bug: #582035)
|
|
|
|
The mke2fs program now queries the kernel for the physical as well as
|
|
the logical sector size, and will not allow a blocksize below the
|
|
logical, and will strongly encourage a blocksize at least as big as
|
|
the physical blocksize. This is needed for 4k sector drives that
|
|
emulate 512 byte sector sizes.
|
|
|
|
Mke2fs will now allow a flex_bg size of 1. This is unusual, and
|
|
rarely needed, but it is a legal value.
|
|
|
|
E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
|
|
not needed, and offer to clear it; this is a sign of a kernel bug, but
|
|
more importantly, some released kernels may crash when this situation
|
|
is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
|
|
|
|
E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
|
|
i_size is correct. (Kernels starting with 2.6.34 will set
|
|
EOFBLOCKS_FL.)
|
|
|
|
The com_err library will now only output ^M (a CR character) when the
|
|
tty is in raw mode.
|
|
|
|
Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
|
|
and Vietnamese translations.
|
|
|
|
Fixed various Debian packaging issues --- see debian/changelog for
|
|
details. (Addresses Debian Bugs: #571247, #563487)
|
|
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
The regression test suite now uses its own mke2fs.conf file, so that
|
|
downstream distributions want change the mke2fs.conf file which is
|
|
distributed in the RPM or dpkg file, without worrying about screwing
|
|
up the regression test results.
|
|
|
|
Always build namei.o so that building with configure --disable-debugfs
|
|
works correctly. Long-term, if we care about reduced e2fsprogs
|
|
builds, we need a more general solution for deciding what .o files are
|
|
needed for a particular build. Given that install floppies are going
|
|
(gone?) the way the dodo bird, we probably don't care, though.
|
|
(Addresses Sourceforge Bug: #2911433)
|
|
|
|
Add configure options --enable-symlink-build and
|
|
--enable-symlink-install, which allow e2fsprogs be built using
|
|
symlinks instead of hard links, and to be installed using symlinks
|
|
instead of hard links, respectively. It is useful when the file
|
|
system where the build is taking place, or the file system where
|
|
e2fsprogs is installed, can't handle hard links for some reason.
|
|
(Addresses Sourceforge Bug: #1436294)
|
|
|
|
Fixed compile warning in mke2fs.c.
|
|
|
|
|
|
E2fsprogs 1.41.11 (March 14, 2010)
|
|
==================================
|
|
|
|
E2fsck will no longer give a fatal error and abort if the physical
|
|
device has been resized beyond 2**32 blocks. (Addresses Launchpad
|
|
Bug: #521648)
|
|
|
|
Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
|
|
the allocation status of the block <blk>. (Addresses Debian Bug:
|
|
#564084)
|
|
|
|
E2fsck now prints a much more emphatic and hopefully scary message
|
|
when a file system is detected as mounted while doing a read/write
|
|
check of the filesystem. Hopefully this will dissuade users from
|
|
thinking, "surely that message doesn't apply to *me*" :-(
|
|
|
|
E2fsck -n will now always open the file system read-only. We now
|
|
disallow certain combination of options which previously were manual
|
|
exceptions; this is bad because it causes users to think they are
|
|
smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
|
|
-D" are no longer supported. (Addresses Launchpad Bug: #537483)
|
|
|
|
In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
|
|
it detected a badly aligned partition. Unfortunately, this broke some
|
|
distribution installation scripts, so it now just prints the warning
|
|
message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
|
|
Launchpad Bug: #530071)
|
|
|
|
Mke2fs would take a long time to create very large journal files for
|
|
ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
|
|
now fixed.
|
|
|
|
E2fsck now understands the EOFBLOCKS_FL flag which will be used in
|
|
2.6.34 kernels to make e2fsck not complain about blocks deliberately
|
|
fallocated() beyond an inode's i_size.
|
|
|
|
E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
|
|
e2fsck -fD can corrupt non-indexed directories when are exists one or
|
|
more file names which alphabetically sort before ".". This can happen
|
|
with ext2 filesystems or for small directories (take less than a lock)
|
|
which contain filenames that begin with a space or some other
|
|
punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
|
|
Bug: #525114)
|
|
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
|
|
correctly.
|
|
|
|
The libcom_err function now has support for Heimdal's com_right_r
|
|
function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian
|
|
Bug: #558910)
|
|
|
|
|
|
E2fsprogs 1.41.10 (February 7, 2010)
|
|
====================================
|
|
|
|
Fix resize2fs bug which causes it to access invalid memory.
|
|
|
|
Add libss support for libreadline.so.6.
|
|
|
|
Fix e2fsck's check for extent-mapped directory with an incorrect file
|
|
type.
|
|
|
|
Add new e2fsck.conf configuration option, default/broken_system_clock
|
|
to support systems with broken CMOS hardware clocks. Also, since too
|
|
many distributions seem to have broken virtualization scripts now,
|
|
e2fsck will by default accept dates which are off by up to 24 hours by
|
|
default. (Addresses Debian Bugs: #559776, #557636)
|
|
|
|
Fix a bug where mke2fs may not use the best placement of the inode
|
|
table when there is only room for a single block group in the last
|
|
flex_bg.
|
|
|
|
E2fsck is now smarter when it needs to allocate blocks in the course
|
|
of fixing file system problems. This reduces the number of spurious
|
|
differences found in pass #5.
|
|
|
|
E2fsck will no longer rehash directories which fit in a single
|
|
directory block.
|
|
|
|
E2fsck now correctly handles holes in extent-mapped directories (i.e.,
|
|
sparse directories which use extents).
|
|
|
|
Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
|
|
|
|
Fix a bug in filefrag where on platforms which can allow file systems
|
|
with 8k blocks, that it doesn't core dump when it sees a file system
|
|
with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
|
|
out.)
|
|
|
|
E2fsck will correctly fix directories that are have an inaccurate
|
|
i_size as well as other problems in a single pass, instead of
|
|
requiring two e2fsck runs before the file system is fully fixed.
|
|
|
|
Fix e2fsck so it will correctly find and detect duplicate directory
|
|
entries for non-indexed directories. ( Addresses Sourceforge Bug:
|
|
#2862551)
|
|
|
|
Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
|
|
thinly-provisioned storage device. This can be disabled using the -K
|
|
option.
|
|
|
|
Enhance libext2fs so it works around bug in Linux version 2.6.19
|
|
and earlier where the /proc/swaps file was missing the header on
|
|
the first line.
|
|
|
|
Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
|
|
was missing the header on the first line.
|
|
|
|
Fix some big-endian bugs in e2fsck and libext2fs.
|
|
|
|
Fix resize2fs so it works correctly on file systems with external
|
|
journals instead of failing early with the error "Illegal inode
|
|
number".
|
|
|
|
Fix libss so that it does not seg fault when using a readline library
|
|
which does not supply a readline_shutdown() function.
|
|
|
|
Updated dumpe2fs's usage message so it correctly gives the right
|
|
arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
|
|
(Addresses Launchpad Bug: #448099)
|
|
|
|
Teach libext2fs to ignore the high 32 bits of the i_blocks field
|
|
when huge_file file system feature is set, but the inode does not
|
|
have the HUGE_FILE_FL flag set.
|
|
|
|
Fix e2fsck's handling of 64-bit i_blocks fields.
|
|
|
|
E2fsck will now print "Illegal indirect block", "Illegal
|
|
double-indirect block", etc., instead of "Illegal block #-1" or
|
|
"Illegal block #-2", etc. This makes it easier for users to
|
|
understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
|
|
|
|
Mke2fs now will obtain get device topology information from blkid and
|
|
use it to populate the superblock stride and stripe sizes. It will
|
|
also warn if the block device is misaligned
|
|
|
|
Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug:
|
|
##524526)
|
|
|
|
Fix the libext2fs library code to round up the bitmap size to a 4-byte
|
|
boundary, to prevent spurious seg faults caused by the x86
|
|
architecture. This doesn't affect Linux systems, but was a major
|
|
problem on a number of *BSD systems. (Addresses Sourceforge Bug:
|
|
#2328708)
|
|
|
|
Fix resize2fs's minimum size required for a file system so it doesn't
|
|
fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131)
|
|
|
|
Dumpe2fs now prints summary information about the contents of the
|
|
journal.
|
|
|
|
Avoid printing scary error messages when e2fsck starts running
|
|
problems on low-memory systems, as it tends to panic and mislead the
|
|
user. (Addresses Debian Bug: #509529)
|
|
|
|
Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
|
|
modules files. (Address Red Hat Bug: #518572)
|
|
|
|
Fix tune2fs so it can add a journal when an extent-enabled file system
|
|
is mounted. (Addresses Launchpad bug: #416648)
|
|
|
|
Update Czech, Indonesian, Polish and Vietnamese translations (from the
|
|
Translation Project).
|
|
|
|
Update/clarify man pages. (Addresses Sourceforge Bug: #2822186)
|
|
|
|
Fixed various Debian packaging issues --- see debian/changelog for
|
|
details. (Addresses Debian Bugs: #540111)

|
Programmer's Notes
|
|
------------------
|
|
|
|
The configure script supports the --with-cc, --with-ccopts, and
|
|
--with-ldopts options. Instead, the more standard use of CC=,
|
|
CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
|
|
Also, --with-ld, which never worked, was also removed.

The in-tree header files are only used if the in-tree uuid or blkid

libraries are used. Otherwise, use the system-provided uuid or blkid
|
|
header files if using the system-provided libraries.

E2fsprogs 1.41.9 (August 22, 2009)
|
|
==================================
|
|
|
|
Fix a bug in e2fsck routines for reallocating an inode table which
|
|
could cause it to loop forever on an ext4 filesystem with the FLEX_BG
|
|
filesystem feature with a relatively rare (and specific) filesystem
|
|
corruption. This fix causes e2fsck to try to find space for a new
|
|
portion of the inode table in the containing flex_bg, and if that
|
|
fails, the new portion of the inode table will be allocated in any
|
|
free space available in the filesystem.
|
|
|
|
Make e2fsck less annoying by only asking for permission to relocate a
|
|
block group's inode table once, instead of for every overlapping
|
|
block. Similarly, only ask once to recompute the block group
|
|
checksums, instead of once for each corrupted block group's checksum.
|
|
|
|
Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
|
|
not present, and it needs to fall back to using the FIBMAP ioctl.
|
|
|
|
Fix filefrag to correctly print the number of extents for zero-length
|
|
files. (Addresses Debian Bug: #540376)
|
|
|
|
Filefrag now has a -B option which forces the use of the FIBMAP ioctl
|
|
to more easily debug the FIBMAP code.
|
|
|
|
Fixed filefrag for non-extent based files.
|
|
|
|
Add a new program, e2freefrag, which displays information about the
|
|
free space fragmentation in an ext2/3/4 filesystem.
|
|
|
|
Fix inode resizing via tune2fs -I so that it works correctly in the
|
|
face of non-empty bad blocks inodes, and if the filesystem was
|
|
formatted using the "mke2fs -E stride=N" option for RAID arrays.
|
|
|
|
Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
|
|
and corrupt large directories if the directory needs to shrink by more
|
|
than one block. (Addresses Debian Bug: #537510)
|
|
|
|
Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
|
|
last mount times are in the future, they are corrected even if
|
|
buggy_init_scripts is set. This is needed because otherwise resize2fs
|
|
will refuse to resize the filesystem, even after running "e2fsck -f".
|
|
(Addresses Launchpad bug: #373409)
|
|
|
|
E2fsck will now print much fuller information when the last mount time
|
|
or last written time is in the future, since most people can't seem to
|
|
believe their distribution has buggy init scripts, or they have a
|
|
failed CMOS/RTS clock battery.
|
|
|
|
Enhance dumpe2fs to dump the extent information via the 'stat'
|
|
command, and more detailed extent information via the new command
|
|
'dump_extents'.
|
|
|
|
Update French, Polish, Czech, and Swedish translations from the
|
|
Translation Project.
|
|
|
|
Fixed various Debian packaging issues --- see debian/changelog for
|
|
details.
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
Fixed miscellaneous gcc -Wall warnings.
|
|
|
|
Fixed memory leak in error path in ext2fs_block_iterate2()
|
|
|
|
Fixed non-Linux build of the intl directory by adding support for the
|
|
E/Q/V macros.
|
|
|
|
The bitmap read/write functions now treat uninitialized bitmaps as
|
|
unallocated; this fixes a number of problems in all e2fsprogs for ext4
|
|
filesystems when there is a need to allocate new blocks or inodes, and
|
|
there aren't any free blocks or inodes in the already-used block
|
|
groups.
|
|
|
|
Improve ext2fs_extent_set_bmap() to avoid creating new extents which
|
|
get inserted into the extent tree when they are not needed.
|
|
|
|
|
|
E2fsprogs 1.41.8 (July 11, 2009)
|
|
================================
|
|
|
|
Fix resize2fs's online resizing, fixing a regression which in
|
|
e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
|
|
|
|
Fix potential filesystem corruptions caused by using resize2fs to
|
|
shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
|
|
Bug: #510379)
|
|
|
|
Optimize uuid_generate() to avoid running uuidd if it is not setuid or
|
|
setgid and the currently running program doesn't have write access to
|
|
the uuidd work directory.
|
|
|
|
Add safety checks (for non-Linux systems) so that uuidd isn't run with
|
|
file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
|
|
will be careful not to close the file descriptor for its unix domain
|
|
socket when it detaches itself from the controlling tty. Also add
|
|
safety checks so that if the unix domain socket between the uuid
|
|
library and uuidd program is closed for any reason, both the library
|
|
and the uuidd will return an appropriate error code instead of looping
|
|
in an infinite loop.
|
|
|
|
The e2croncheck script, which creates an LVM snapshot and then checks
|
|
the ext3/4 filesystem via the LVM snapshot, has been added to the
|
|
contrib directory.
|
|
|
|
Fix the filefrag program for files that have more than 144 extents.
|
|
|
|
Update French, Polish, Czech, Indonesian, and Swedish translations from
|
|
the Translation Project.
|
|
|
|
Fixed various Debian packaging issues --- see debian/changelog for
|
|
details. (Addresses Debian Bug #535530)
|
|
|
|
Update/clarify man pages.
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
Fix compilation problem when configured with --disable-uuid.
|
|
|
|
Don't build uuidgen if configured with --disable-uuid.
|
|
|
|
Add the new library function ext2fs_test_inode_bitmap_range(), and
|
|
optimized ext2fs_test_block_bitmap_range(), which will be needed for
|
|
future optimizations for e2fsck.
|
|
|
|
Fix makefile dependencies for libcom_err so that the Makefiles work
|
|
well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
|
|
|
|
Enhance the build system so that the full set of commands executed by
|
|
the Makefiles are displayed, instead of the Linux kernel summary
|
|
output, if the build was configured with --enable-verbose-makecmds, or
|
|
if GNU make is in use and the V variable is non-null, i.e., via "make
|
|
V=1".
|
|
|
|
|
|
E2fsprogs 1.41.7 (June 29, 2009)
|
|
================================
|
|
|
|
Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
|
|
uninitialized data into the portion of the inode beyond the first 128
|
|
bytes when operating on inodes mapped via extents; potentially
|
|
corrupting filesystems.
|
|
|
|
Fix memory leaks in e2fsprogs, including a very large memory leak
|
|
which can cause e2fsck to run out of memory when checking very large
|
|
filesystems using extents.
|
|
|
|
The logsave program will now filter out the ^A and ^B characters when
|
|
writing to the console.
|
|
|
|
Harden ext2fs_validate_entry() so that lsdel will not read beyond the
|
|
end of the block even if the directory block is corrupted.
|
|
|
|
Fix debugfs from core dumping if the logdump command fails to open the
|
|
output file.
|
|
|
|
Enhance badblocks to print the currently tested block number when
|
|
interrupted with ^C.
|
|
|
|
Fix lsattr to exit with a non-zero status when it encounters errors.
|
|
(Addresses RedHat Bugzilla #489841)
|
|
|
|
Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
|
|
filesystems as the kernel when encoding rec_len >= 64k. For 64k
|
|
filesystems (currently all that is supported by e2fsprogs, this is
|
|
only a minor corner case).
|
|
|
|
Resize2fs will now update the journal backup fields in the superblock
|
|
if the journal is moved; this avoids an unnecessary full fsck after
|
|
resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
|
|
|
|
Fix libext2fs to properly initialize i_extra_size when creating the
|
|
journal and resize inodes.
|
|
|
|
Change badblocks to allow block sizes larger than 4k.
|
|
|
|
Fix the filefrag program so it correctly checks for errors from the
|
|
fiemap ioctl.
|
|
|
|
Update Chinese and Czech translation from the Translation Project.
|
|
|
|
Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
|
|
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
Add --disable-libuuid option to configure which uses an in-system
|
|
installed version of libuuid; the private version is enabled by
|
|
default.
|
|
|
|
Add --valgrind-leakcheck option to the test_script program which runs
|
|
valgrind with the appropriate options to find memory leaks.
|
|
|
|
|
|
E2fsprogs 1.41.6 (May 30, 2009)
|
|
===============================
|
|
|
|
Fix a critical regression in e2fsck introduced version 1.41.5 which
|
|
can undo updates to the block group descriptors after a journal replay.
|
|
|
|
If e2fsck receives an I/O error while replaying the journal, prompt
|
|
the user whether they want to ignore the error or not; if e2fsck is
|
|
run in preen mode, force fsck to abort the preen pass.
|
|
|
|
Fix a bug which would cause e2fsck to core dump if the filesystem
|
|
contains a corrupt extent header, and the user declines to clear the
|
|
inode. (Addresses Sourceforge Bug: #2791794)
|
|
|
|
Fix e2fsck to restart only once in the case of multiple block groups
|
|
which inodes in use that are in the uninitialized part of the block
|
|
group's inode table.
|
|
|
|
To reduce user confusion, if the /etc/mtab file is missing
|
|
ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
|
|
new, explicit error code to indicate this case. This will cause
|
|
e2fsck to give a clearer error message when the user is using buggy
|
|
rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
|
|
Bug: #527859)
|
|
|
|
Fix e2fsck so that if the primary group descriptors are corrupted, but
|
|
the backup superblock is entirely invalid, to go back to using (and
|
|
fixing) the primary group descriptors instead of completely giving up
|
|
on the filesystem. (Addresses Debian Bug: #516820)
|
|
|
|
Change e2fsck to not abort a preen pass if an inode is found to have
|
|
i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
|
|
kernels (post 2.6.29) will ignore this field. So let's fix it
|
|
automatically during the preen pass instead of forcing the user to fix
|
|
this up manually. (Addresses Debian Bug: #526524)
|
|
|
|
Add resource tracking for e2fsck passes 1b through 1d.
|
|
|
|
Speed up e2fsck by eliminating unnecessary journal checks if the
|
|
filesystem is already mounted and doesn't need recovery (since the
|
|
kernel would have run the journal when the filesystem was mounted.)
|
|
Also speed up e2fsck by avoiding unnecessary block group descriptor
|
|
updates in ext2fs_close().
|
|
|
|
Add support to chattr to migrate inodes from using direct/indirect
|
|
blocks to extents.
|
|
|
|
Avoid corrupting the filesystem if there is an attempt to shrink a
|
|
filesystem using resize2fs smaller than possible by making
|
|
ext2fs_set_bmap() more careful not to delete the old block until the
|
|
new block can be inserted. In addition, fix a bug in how the minimum
|
|
size of the filesystem (plus a safety margin) is calculated, and
|
|
modify resize2fs to refuse to shrink the filesystem below that minimum
|
|
size without the force flag.
|
|
|
|
Teach blkid to try to figure out DM device names using take advantage
|
|
of information in sysfs when running on kernels (2.6.29 and later)
|
|
which provide this information in /sys/block/dm-<N>/dm/name; this is
|
|
much faster than scanning for the device number in /dev/mapper.
|
|
|
|
Fix blkid to prefer /dev/mapper/<name> device names instead of the
|
|
private /dev/dm-X names.
|
|
|
|
Add an -a option to debugfs's close_filesys command which writes any
|
|
changes to the superblock or block group descriptors to all of the
|
|
backup superblock locations.
|
|
|
|
Add support to the filefrag program to use the FIEMAP ioctl.
|
|
|
|
Update Chinese translation from the Translation Project.
|
|
|
|
Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
|
|
Launchpad Bug: #381854)
|
|
|
|
Fixed various Debian packaging issues --- see debian/changelog for
|
|
details. (Addresses Debian Bug #506064)
|
|
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
Add test code to make sure e2fsck's problem.c doesn't have two problem
|
|
codes assigned to duplicate values.
|
|
|
|
Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
|
|
(Addresses Sourceforge Bug: #2780205)
|
|
|
|
Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
|
|
function declaration for init_resource_track() and
|
|
print_resource_track() when RESOURCE_TRACK is not defined.
|
|
|
|
The test code which is used to build the tst_csum program has been
|
|
moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
|
|
avoid compile problems caused by not having a prototype for
|
|
ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
|
|
|
|
Update the config.guess and config.sub file to the latest from the
|
|
FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
|
|
Debian Bug: #528330)
|
|
|
|
Add a new function, ext2fs_extent_open2(), which behaves like
|
|
pext2fs_extent_open(), but uses the user-supplied inode structure
|
|
when opening an extent instead of reading the inode from disk.
|
|
|
|
|
|
E2fsprogs 1.41.5 (April 23, 2009)
|
|
=================================
|
|
|
|
Fix a number of filesystem corruption bugs in resize2fs when growing
|
|
or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
|
|
is not mounted).
|
|
|
|
Debugfs can now set i_file_acl_high via the set_inodes_field command,
|
|
and print a 64-bit file acl. This is useful for debugging filesystem
|
|
corruptions where the high bits of i_file_acl_high are set. E2fsck
|
|
will detect and fix non-zero i_file_acl_high on 32-bit filesystems
|
|
since some Linux kernel versions pay attention to this field even when
|
|
they shouldn't.
|
|
|
|
Speed up e2fsck when checking clean filesystems by avoiding
|
|
unnecessary block reads, and coalescing the block group descriptor
|
|
blocks so they are read using a single read operation.
|
|
|
|
The libuuid library will now close all file descriptors before running
|
|
uuidd. This avoids problems when the calling program has open sockets
|
|
which then never get closed because uuidd is a long-running helper
|
|
daemon. (Addresses Launchpad bug: #305057)
|
|
|
|
In order to avoid unnecessary full filesystem checks by e2fsck after
|
|
an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
|
|
the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
|
|
|
|
Mke2fs will avoid trying to create the journal when run in
|
|
superblock-only mode (mke2fs -S), since the left-over journal in the
|
|
inode table will cause mke2fs to fail.
|
|
|
|
Fix a bug in libext2fs functions that check to see if a particular
|
|
device or filesystem image is mounted, which would cause these
|
|
functions to report that a file identical to the (relative) pathname
|
|
used by a pseudo-filesystem was mounted when in fact it was not.
|
|
|
|
Update Czech translation from the Translation Project.
|
|
|
|
Add Chinese (simplified) translation from the Translation Project.
|
|
|
|
Fix support for external journals (which was broken in e2fsprogs
|
|
1.41.4).
|
|
|
|
Fix a regression in debugfs where the "stat" command when no
|
|
filesystem was open would cause debugfs to crash with a segmentation
|
|
violation.
|
|
|
|
Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
|
|
used to support filesystems without a journal. Update the blkid
|
|
library so it understands this.
|
|
|
|
The blkid library will remove an entry from the blkid cache
|
|
representing the entire disk if partitions are found, since presumably
|
|
the device previously had no partition table, but has now transitioned
|
|
to using a partition table.
|
|
|
|
Add a check to mke2fs and tune2fs that the argument to the -m option
|
|
(which specifies the reserved ratio) must be greater than zero.
|
|
(Addresses Debian Bug: #517015)
|
|
|
|
Add support for tracking the number kilobytes written to the
|
|
filesystem via the superblock field s_kbytes_written. It will be
|
|
updated by the kernel as well as by e2fsprogs programs which write to
|
|
the filesystem. This is useful for tracking the wear to filesystems
|
|
on Solid State Drives.
|
|
|
|
Fix compatibility issue in the libext2fs info file and makeinfo
|
|
version 4.12. (Addresses Red Hat Bugzilla: #481620)
|
|
|
|
Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
|
|
|
|
Fixed various Debian packaging issues --- see debian/changelog for
|
|
details. (Addresses Debian Bug: #506279)
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
|
|
Bug: #521602)
|
|
|
|
Fix various gcc compilation warnings and other programming cleanups.
|
|
(Addresses Red Hat Bugzilla: #486997)
|
|
|
|
Add support for building the blkid command statically.
|
|
|
|
Add support for disabling the built-in blkid library in favor of a
|
|
system-installed blkid implementation via the configure option
|
|
--disable-libblkid.
|
|
|
|
|
|
E2fsprogs 1.41.4 (January 27, 2009)
|
|
===================================
|
|
|
|
Fixed a bug which could sometimes cause blkid to return an exit value
|
|
of zero for a non-existent device (Addresses Debian Bug: #502541)
|
|
|
|
Blkid will now recognize ext3 filesystems that have the test_fs flag
|
|
set as ext3 filesystems.
|
|
|
|
The blkid library will now recognize btrfs filesystems and swap
|
|
devices currently used by user-level software suspend.
|
|
|
|
Tune2fs now updates the block group checksums when changing the UUID
|
|
to avoid causing e2fsck to complain vociferously at the next reboot.
|
|
|
|
Tune2fs's inode size resizing algorithms have been fixed so it is not
|
|
vastly inefficient for moderate-to-large filesystems, due to some
|
|
O(n**2) and O(n*m) algorithms that didn't scale well at all.
|
|
|
|
Fix tune2fs's inode resizing algorithm so it will not corrupt
|
|
filesystems laid out for RAID filesystems; in addition, tune2fs will
|
|
refuse to change the inode size for filesystems that have the flex_bg
|
|
feature enabled. (This is a limitation in the current implementation
|
|
of tune2fs -I.)
|
|
|
|
E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
|
|
filesystems with 32-bit block numbers, when the headers for 64-bit
|
|
block numbers was added. This regression has been fixed.
|
|
|
|
Debugfs's ncheck command has been fixed to avoid printing garbage
|
|
characters at the end of file names.
|
|
|
|
Fix resize2fs for ext4 filesystems. Some blocks that that need moving
|
|
when shrinking filesystems with uninit_bg feature would not be moved.
|
|
In addition, blocks and inode table blocks were not being correctly
|
|
freed when shrinking filesystems with the flex_bg feable, which caused
|
|
resize2fs -M to fail. Finally, when blocks are moved, make sure the
|
|
uninitialized flag in extents is preserved.
|
|
|
|
Fix bug which caused dumpe2fs to abort with an error if run on a
|
|
filesystem that contained an external journal.
|
|
|
|
Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
|
|
for this in argv[0] to provide better legacy support for these
|
|
distributions. This is a practice that should NOT be continued,
|
|
however.
|
|
|
|
Mke2fs now has a new option -U, which allows the user to specify the
|
|
UUID that should be used for the new filesystem.
|
|
|
|
Mke2fs will treat devices that are exactly 16TB as if they were 16TB
|
|
minus one block. This allows users who have read that ext3 supports
|
|
up to 16TB filesystems and who create a 16TB LVM to not get confused,
|
|
since the true limit is really 16TB minus one block.
|
|
|
|
E2fsck will no longer abort an fsck run if block group has an errant
|
|
INODE_UNINIT flag.
|
|
|
|
E2fsck now distinguishes between fragmented directories and fragmented
|
|
files in verbose mode statistics and in the fragcheck report.
|
|
|
|
Fix a bug in e2fsck which caused it double count non-contiguous
|
|
extent-based inodes.
|
|
|
|
E2fsck will leave some slack space when repacking directories to allow
|
|
room for a few directory entries to be added without causing leaf
|
|
nodes to be split right away.
|
|
|
|
Fix a bug which caused e2fsck to crash when it comes across a
|
|
corrupted interior node in an extent tree with the error message:
|
|
"Error1: Corrupt extent header on inode XXXXXX"
|
|
|
|
E2fsck problem descriptions involving the journal are no longer
|
|
referred to as "ext3" problems, since ext4 filesystems also have
|
|
journals.

Programmer's Notes
|
|
------------------
|
|
|
|
Fix build of e2fsck.profiled, and add support for building profiled
|
|
binaries in the misc directory if configured with --enable-profile.
|
|
|
|
The ext2fs_open() function now performs more sanity checks on the
|
|
superblock to avoid potential divide by zero errors by other parts of
|
|
library.
|
|
|
|
The ext2fs_read_inode_full() function now has a safety check to avoid
|
|
a segmentation fault on corrupted filesystems.
|
|
|
|
The ext2fs_new_inode() function now has a sanity check so that if the
|
|
s_first_inode field in the superblock is insane, it will return
|
|
EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
|
|
|
|
To avoid segmentation faults, ext2fs_block_alloc_stats() and
|
|
ext2fs_inode_alloc_stats() now validates the passed inode or block
|
|
number to avoid overrunning an array boundary.
|
|
|
|
Various signed/unsigned errors for variables containing block numbers
|
|
have been fixed.
|
|
|
|
Accommodations for gcc's stupidity in not realizing that constant
|
|
strings that do not contain a '%' character are safe to use in format
|
|
strings have been made so that distributions that want to compile
|
|
e2fsprogs with -Werror=format-security have an easier time doing so.
|
|
|
|
Added a new 64-bit getsize interface, ext2fs_get_device_size2().
|
|
|
|
Added the utility make-sparse.c to the contrib directory.
|
|
|
|
The ext2fs_block_iterate2() function now reflects errors from
|
|
ext2fs_extent_set_bmap() to the caller, if the callback tries to
|
|
change a block on an extent-based file, and ext2fs_extent_set_bmap()
|
|
fails for some reason (for example, there isn't enough disk space to
|
|
split a node and expand the extent tree.
|
|
|
|
The ext2fs_block_iterate2() function will preserve the uninit flag in
|
|
extents when the callback function modifies a block in an extent-based
|
|
file.
|
|
|
|
E2fsck will now flag filesystems that have an insane s_first_ino field
|
|
in their superblock, and attempt to use a backup superblock to repair
|
|
the filesystem.
|
|
|
|
|
|
E2fsprogs 1.41.3 (October 12, 2008)
|
|
===================================
|
|
|
|
E2fsck has been fixed so it prints the correct inode number for
|
|
uinit_bg related problems.
|
|
|
|
E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
|
|
is available on linux. This can be disabled via a configuration
|
|
option in /etc/e2fsck.conf.
|
|
|
|
Fix a file descriptor leak in libblkid when checking to see if an ext4
|
|
or ext4dev module exists.
|
|
|
|
Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
|
|
while trying to close a filesystem can lead to infinite loops.
|
|
(Addresses Red Hat Bugzilla #465679)
|
|
|
|
Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
|
|
will cause resize2fs to drop into an infinite loop. (Addresses Red
|
|
Hat Bugzilla: #465984)
|
|
|
|
Add a check in the Unix I/O functions in libext2fs so that when a
|
|
device is opened read/write, return an error if the device is
|
|
read-only using the BLKROGET ioctl.
|
|
|
|
Fix debugfs's ncheck command so that it prints all of the names of
|
|
hardlinks in the same directory.
|
|
|
|
Fix a bug in libblkid so it correctly detects whether the ext4 and
|
|
ext4dev filesystems are available, so that the ext4dev->ext4
|
|
fallback code works correctly.
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
Fix a parallel build problem by making sure util/subst is built before
|
|
trying to build the lib/et directory. (Addresses Sourceforge Bug:
|
|
#2143281)
|
|
|
|
Updated "make depend" information for crc16.o
|
|
|
|
|
|
E2fsprogs 1.41.2 (October 2, 2008)
|
|
==================================
|
|
|
|
Fix e2fsck's automatic blocksize detection. This fixes a regression
|
|
from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
|
|
specifies a block number using the -b option if the blocksize option
|
|
isn't also specified using -B. Unfortunately, users very commonly
|
|
invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
|
|
superblock; in fact e2fsck will often suggest this kind of command
|
|
line. Oops.
|
|
|
|
Enhance the debugfs's "ncheck" command so it will print all of the
|
|
pathnames for the specified inodes. (Previously, in some cases ncheck
|
|
might not print a pathname for an inode at all if some of the other
|
|
inodes had multiple hard links.)
|
|
|
|
Enhance debugfs's "hash" command so the hash seed can be specified via
|
|
a command-line option. In addition, allow the hash algorithm to be
|
|
specified by name instead of just by number.
|
|
|
|
Fix e2fsck so that we don't accidentally print the translation file's
|
|
header when asking the user a custom question so there is no prompt
|
|
defined for a particular problem record. For example, the question
|
|
"Run journal anyway" will get the PO header tacked on because e2fsck
|
|
erroneously passed the null string to _(). (Addresses Launchpad Bug:
|
|
#246892)
|
|
|
|
Enhance badblocks so that it can test a normal file which is greater
|
|
than 2GB.
|
|
|
|
Enhance the badblocks command so that it displays the time and
|
|
percentage complete when in verbose mode. (Addresses Debian Bug:
|
|
#429739)
|
|
|
|
Fix a potential memory leak in a error handling path in debugfs's
|
|
ncheck function.
|
|
|
|
Fix a potential memory corruption problem if a memory allocation fails
|
|
in resize2fs.
|
|
|
|
Fix the usage message for debugfs's logdump command to be consistent
|
|
with its man manpage.
|
|
|
|
Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
|
|
and Swedish translations from the Translation Project.
|
|
|
|
Add documentation for the file I/O functions to the libext2fs.texinfo
|
|
file. (Addresses Debian Bug: #484877)
|
|
|
|
Update and clarified various man pages. (Addresses Launchpad Bug
|
|
#275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
|
|
|
|
Fixed various Debian packaging issues --- see debian/changelog for
|
|
details. (Addresses Debian Bug: #497619)
|
|
|
|
Programmer's Notes
|
|
------------------
|
|
|
|
Fix a potential file descriptor leak in libcom_err by setting the
|
|
close-on-exec flag for a fd used for debugging. (Addresses Red Hat
|
|
Bugzilla #464689)
|
|
|
|
Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
|
|
has been carrying a patch for a long time to prevent a largely
|
|
theoretical race condition if a multi-threaded application adds and
|
|
removes error tables in multiple threads. Unfortunately SuSE's
|
|
approach breaks compatibility by forcing applications to link and
|
|
compile with the -pthread option; using pthread mutexes has
|
|
historically been problematic. We fix this by using sem_post/sem_init
|
|
instead.
|
|
|
|
Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
|
|
Sourceforge Bug: #2087502)
|
|
|
|
Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
|
|
libraries when using ELF shared libraries.
|
|
|
|
Fix ELF shared library when building on systems that don't already
|
|
have the e2fsprogs shared libraries already installed. (Addresses
|
|
Sourceforge Bug: #2088537)
|
|
|
|
Fix the pkg-config files so they work correctly when linking with
|
|
static libraries and fix the include directory so programs don't have
|
|
to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
|
|
instead. (Addresses Sourceforge Bug: #2089537)
|
|
|
|
Make sure ext2fs_swab64() is compiled for all platforms, and not just
|
|
for x86. (Addresses Debian Bug: #497515)
|
|
|
|
Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
|
|
non-x86 platforms. (They had been removed for x86 earlier.)
|
|
|
|
Fix diet libc compilation support, which had bitrotted due to lack of
|
|
TLC. Fixing this improves general portability.
|
|
|
|
When installing the link library when using ELF shared libraries,
|
|
avoid using absolute pathnames if the link library and the shared
|
|
library are installed in the same directory. (Addresses Sourceforge
|
|
Bug: #1782913)
|
|
|
|
Fix gen-tarball so it will work even if the top-level directory has
|
|
been renamed to something other than "e2fsprogs". Also make
|
|
gen-tarball print the size of the resulting tar.gz file.
|
|
|
|
|
|
E2fsprogs 1.41.1 (September 1, 2008)
|
|
====================================
|
|
|
|
Many people are forgetting to update their mke2fs.conf file, and this
|
|
causes ext3, ext4, and ext4dev filesystems won't get created with the
|
|
proper features enabled. We address this in two ways. First, mke2fs
|
|
will issue a warning if there is not definition for an ext3, ext4, or
|
|
ext4dev filesystem and the user is trying to create such a filesystem
|
|
type. Secondly, when installing from a source build, "make install"
|
|
will provide basic configuration file handling for /etc/mke2fs.conf.
|
|
If it exists, and does not mention ext4dev, it will be moved aside to
|
|
/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
|
|
be installed. If the existing /etc/mke2fs.conf file does mention
|
|
ext4dev, then "make install" will install official mke2fs.conf file as
|
|
/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
|
|
they should look to see if any changes need to be merged.
|
|
|
|
The mke2fs program will now create the journal in the middle of the
|
|
filesystem, since this minimizes seek times on average for fsync-heavy
|
|
workloads. In addition, mke2fs will now create journals using extents
|
|
for filesystems that support them. This results in a more efficient
|
|
encoding for the journal since it eliminates the need for using
|
|
indirect blocks.
|
|
|
|
The mke2fs program will avoid allocating an extra block to the
|
|
journal. (Addresses Sourceforge Bug: #1483791)
|
|
|
|
Mke2fs will correctly enforce the prohibition against features
|
|
(specifically read-only features) in revision 0 filesystems. (Thanks
|
|
to Benno Schulenberg for noticing this problem.)
|
|
|
|
Mke2fs previously would occasionally create some slightly non-optimally
|
|
placed inode tables; this bug has been fixed.
|
|
|
|
The mke2fs and tune2fs programs now print the correct usage message
|
|
describing the maximum journal size. (Addresses Debian Bug: #491620)
|
|
|
|
Add support for setting the default hash algorithm used in b-tree
|
|
directories in tune2fs (from a command-line option) or mke2fs (via
|
|
mke2fs.conf). In addition, change the default hash algorithm to
|
|
half_md4, since it is faster and better.
|
|
|
|
The blkid library will now recognize MacOS hfsx filesystems, and
|
|
correctly extract the label and uuid for hfs, hfsx, and hfsplus
|
|
filesystems. (Addresses Sourceforge Feature Requests: #2060292)
|
|
|
|
The blkid library has improved detection of JFS and HPFS filesystems.
|
|
(Addresses Launchpad Bug: #255255)
|
|
|
|
The blkid library is now much more efficiently handling devicemapper
|
|
devices, mainly by no longer using the devicemapper library. This can
|
|
speed up access for systems with a large number of device mapper
|
|
devices.
|
|
|
|
Blkid had a number of cache validation bugs in libblkid that have been
|
|
fixed. (Addresses Debian Bug: #493216)
|
|
|
|
Resize2fs will now properly close out the "updating inode references"
|
|
progress bar so there is a newline printed before printing the final
|
|
"resize is successful" message.
|
|
|
|
Resize2fs will now correctly handle filesystems with extents and/o
|
|
uninitialized block groups correctly when file/directory blocks need
|
|
to relocated (i.e., when shrinking a filesystem or if the resize_inode
|
|
is not present). To support this, the ext2fs library now supports
|
|
initializing inode and block bitmaps that are not yet initialized when
|
|
allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
|
|
addition, e2fs_block_iterate2() can now support changing the location
|
|
of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
|
|
been optimized to avoid creating unnecessary new extents when updating
|
|
the location of blocks in the extent tree. This will also help out
|
|
e2fsck's recovery of obscurely corrupted filesystems with extents,
|
|
when blocks are claimed by multiple inodes.
|
|
|
|
Add support for on-line resizing ext4 filesystem with the flex_bg
|
|
filesystem feature. The method for doing so is not optimal, but to do
|
|
a better job will require kernel support.
|
|
|
|
E2fsprogs 1.41.0 introduced a bug in libext2fs which caused e2image and
|
|
debugfs programs to not be able to read e2image files; the signed
|
|
vs. unsigned bug in the code which read bitmaps from the e2image has
|
|
been fixed. (Addresses Debian Bug: #495830)
|
|
|
|
Resize2fs is now correctly managing the directory in-use counts when
|
|
shrinking filesystems and directory inodes needed to be moved from one
|
|
block group to another. This bug has been around since e2fsprogs
|
|
1.26, and is largely harmless, but does cause a filesystem corruption
|
|
which will be flagged by e2fsck after the filesystem has been shrunk.
|
|
|
|
E2fsck will no longer issue spurious complaints about the inode size
|
|
caused by very large extent-based files, and by blocks reallocated
|
|
using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
|
|
Kernel Bugzilla: #11341)
|
|
|
|
Mke2fs will now set the creation timestamp on the lost+found directory
|
|
and the root directory. (More generally, all new inodes created using
|
|
the ext2fs library will correctly set the creation timestamp.)
|
|
|
|
E2fsck now correctly calculates ind/dind/tind statistics in the
|
|
presence of extent-based files. In addition, "e2fsck -v" will report
|
|
statistics of the depth of extent trees in the filesystem. E2fsck can
|
|
also give an inode fragmentation report using "e2fsck -E fragcheck"
|
|
which can be useful when debugging the kernel block allocation
|
|
routines.
|
|
|
|
Fix support for empty directory blocks in ext4 filesystems with 64k
|
|
blocksize filesystems.
|
|
|
|
E2fsck will now print the depth of corrupt htree directories.
|
|
|
|
Debugfs's htree command now correctly understands extent-based
|
|
directories. It will also print out the minor hash as well as the
|
|
major hash.
|
|
|
|
Debugfs has a new command which will print the supported features of
|
|
e2fsprogs, to enable scripts to know whether the installed version of
|
|
e2fsprogs can support a specific feature.
|
|
|
|
Debugfs will now write files using extents for filesystems that
|
|
support them.
|
|
|
|
The error message printed by "tune2fs -I" if the inode size was too
|
|
small was rather confusing, so it has been improved. Also, we won't
|
|
try to create an undo log until we know that command-line-specified
|
|
parameters such as "tune2fs -I <inode size>" are valid.
|
|
|
|
Given some filesystems found "in the wild" that had non-zero block
|
|
group checksums even though the uninit_bg/gdt_sum feature was not
|
|
enabled, e2fsck would issue spurious error messages. Teach
|
|
ext2fs_group_desc_csum_verify() to ignore the block group checksum
|
|
entirely if the feature flag is not set. (Addresses Debian Bug:
|
|
#490637)
|
|
|
|
The blkid program will now print out a user-friendly listing of all of
|
|
the block devices in the system and what they contain when given the
|
|
-L option. (Addresses Debian Bug: #490527)
|
|
|
|
The filefrag program now has a more accurate calculation for the
|
|
number of ideal extents. (Addresses Debian Bug: #458306)
|
|
|
|
The test I/O manager is now enabled by default, but its overhead is
|
|
only incurred when it would be enabled via the TEST_IO_FLAGS or
|
|
TEST_IO_BLOCK environment variables.
|
|
|
|
Typographical errors in various program strings and usage messages
|
|
have been fixed; most of these were pointed out by the e2fsprogs
|
|
message catalog translators. (Thanks, translators!)
|
|
|
|
Update and clarified various man pages, as well as some typographical
|
|
errors in the libext2fs texinfo file.
|
|
|
|
Fixed various Debian packaging issues --- see debian/changelog for
|
|
details.
|
|
|
|
Add Indonesian and update French, Polish, Dutch, German, Swedish,
|
|
Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
|
|
#401092)

Programmer's Notes
|
|
------------------
|
|
|
|
Fix portability problem with the badblocks group; for systems that
|
|
don't have nanosleep(), try using usleep() instead.
|
|
|
|
The "make check" target in the e2fsck directory now sets
|
|
LD_LIBRARY_PATH before running the various e2fsck internal library
|
|
regression tests.
|
|
|
|
The crc32 regression test in the e2fsck library is now portable to
|
|
greater variety of environments, including big-endian systems and
|
|
when cross-building e2fsprogs for embedded systems. (Addresses
|
|
Sourceforge Bug: #2019287)
|
|
|
|
The ext2fs_extent_set_bmap() had some bugs when setting the first
|
|
block in a file, or when replacing a single block extent. Those cases
|
|
fortunately were came up relatively rarely when e2fsck was checking
|
|
files, but caused some problems when resize2fs was shrinking
|
|
extent-based files.
|
|
|
|
Fix a potential core-dumping bug in libe2p's iterate_on_dir()
|
|
function.
|
|
|
|
Various ext2fs library functions --- ext2fs_block_iterate2(),
|
|
ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
|
|
allocated memory to avoid memory leaks in all of their error return
|
|
paths.
|
|
|
|
Ext2ed was failing to build because masix support had been removed in
|
|
the rest of e2fsprogs, so ext2ed no longer has masix support, either.
|
|
|
|
The configure script now respects the LDFLAGS environment variable if
|
|
it is set when configure is called. (Addresses Sourceforge Feature
|
|
Request: #1937287)
|
|
|
|
Libuuid is now more portable to the Windows platform. (Addresses
|
|
Sourceforge Feature Request: #1937287)
|
|
|
|
The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
|
|
bare echo commands so that configure flags such as --quiet work
|
|
correctly. (Addresses Sourceforge Patches: #2058794)
|
|
|
|
A few uses of sprintf have been removed from the ext2fs library to
|
|
make life easier for bootloaders with a limited libc environment.
|
|
(Addresses Sourceforge Bug: #2049120)
|
|
|
|
The ext2fs_read_inode() checks the validity of the inode number passed
|
|
to it earlier, to avoid doing some needless work when it would fail
|
|
anyway.
|
|
|
|
The ext2fs_open() checks the validity of the blocksize parameter
|
|
passed to it earlier, to avoid doing some needless work when it would
|
|
fail anyway.
|
|
|
|
Disable a very annoying automatic "%.sh -> %" GNU make rule in the
|
|
top-level Makefile. That automatic rule is used to better support
|
|
SCCS, but it caused problems for a particular niche distribution which
|
|
likes to use configure.sh files to store the configure options used to
|
|
build a package. Unfortunately GNU make will use the configure.sh to
|
|
replace the configure script, resulting in a self-inflicted fork bomb
|
|
leading to an out-of-memory crash.
|
|
|
|
To support old GNU C compilers don't use C99/C++ comments, but only
|
|
K&R style comments, and don't try to use __builtin_expect if __GNUC__
|
|
is less than 3. (__builtin_expect is only supported for gcc versions
|
|
2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
|
|
this is an optimization, we only try to use __builtin_expect for gcc 3
|
|
and up.)
|
|
|
|
In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
|
|
__LITTLE_ENDIAN, which are only defined by glibc's header files and
|
|
hence isn't portable.
|
|
|
|
For the convenience for some distributions that need a static tune2fs,
|
|
the Makefile for misc/ now has a tune2fs.static target.
|
|
|
|
The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
|
|
for extent-based files
|
|
|
|
The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
|
|
files.
|
|
|
|
All source files no longer have any trailing white space.
|
|
|
|
The io_channel_read_blk64() and io_channel_write_blk64() functions are
|
|
now functions instead of C preprocessor macros to provide better
|
|
forward compatibility.
|
|
|
|
The e2fpsrogs translation template now expands the @x abbreviation.
|
|
|
|
Various namespace leakages in libblkid, libe2p, and libext2fs have
|
|
been fixed.
|
|
|
|
Fix a parallel build problem in e2fsprogs.
|
|
|
|
E2fsprogs is now more portable to Solaris.
|
|
* blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
|
|
are always present.
|
|
* Scripts do not assume that /bin/true is always in /bin
|
|
* Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
|
|
* Flush stdio handles before calling setbuf(), since Solaris will
|
|
discard any pending output to the stream.
|
|
* Define _XOPEN_SOURCE to 600 since Solaris's header files are very
|
|
picky about which C compiler can be used for SUSv3 conformance.
|
|
Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
|
|
and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
|
|
Since we need some SUSv3 functions, consistently use SUSv3 so
|
|
that e2fsprogs will build on Solaris using c99.
|
|
* Solaris C99 does not support varargs C preprocessor macros
|
|
* Solaris header files pollute the C namespace if in/netinet.h
|
|
is included, which conflicts with e2fsprogs' use of the kmem_cache_t
|
|
typedef.
|
|
* Solaris ships with a pathetically ancient shell in /bin/sh so we
|
|
avoid the use of various more advanced shell constructs such as $().
|
|
|
|
The "make rpm" command will now take some extra configure options from
|
|
the build environment without needing to patch the source tree.
|
|
|
|
The ext2fs_add_dir_block() function will now grow the dblist more
|
|
aggressively as an optimization to avoid copying the array too often.
|
|
|
|
The e2fsck_write_bitmaps() will write the block and inode bitmaps
|
|
together instead of in two passes.

E2fsprogs 1.41 (July 10, 2008)
|
|
==============================
|
|
|
|
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)
|
|
|
|
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.
|
|
|
|
Add support for "undo" support. E2fsck and mke2fs can optionally
|
|
record an undo log which can replayed by the program e2undo.
|
|
|
|
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)
|
|
|
|
E2fsck will display a more understandable message when the last check
|
|
field in the superblock is in the future. (Addresses Debian Bug:
|
|
#446005).
|
|
|
|
E2fsck now performs more extensive and careful checks of extended
|
|
attributes stored in the inode.
|
|
|
|
Enhance mke2fs to print a more explanatory error message when
|
|
ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
|
|
#488663)
|
|
|
|
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)
|
|
|
|
Speed up how mke2fs writes the journal data blocks by writing the disk
|
|
blocks in larger chunks.
|
|
|
|
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)
|
|
|
|
Add more paranoid checks for LVM volumes and swap partitions in
|
|
blkid's probe function, to reduce the chances of false positives.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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)
|
|
|
|
Mke2fs will always make sure that lost+found always has at least 2
|
|
blocks, even for filesystems with very large blocksizes (i.e., 64kb).
|
|
|
|
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.
|
|
|
|
Fix resize2fs to clean up the resize_inode if all of the reserved gdt
|
|
blocks are consumed during an off-line resize.
|
|
|
|
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)
|
|
|
|
Fix a potential off-by-one buffer overflow in the fs_device_name in an
|
|
e2image file.
|
|
|
|
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)
|
|
|
|
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)
|
|
|
|
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.
|
|
|
|
Remove support for the legacy big-endian filesystem format which only
|
|
existed on extremely long-dead PowerPC kernels almost a decade ago.
|
|
|
|
Remove MASIX support from e2fsprogs.
|
|
|
|
Add I/O statistics reporting to e2fsck.
|
|
|
|
Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
|
|
Czech translations.
|
|
|
|
Fixed various Debian packaging issues --- see debian/changelog for
|
|
details. (Addresses Debian Bugs: #487443, #487675, #490003)
|
|
|
|
Fixed spelling mistakes, typos, and otherwise clarified man pages.
|
|
(Addresses Debian Bugs: #393313, #487849, #440983, #440981)

Programmer's Notes
|
|
------------------
|
|
|
|
Factor out bitmap code in preparation for adding 64-bit new-style
|
|
bitmaps.
|
|
|
|
Fix gcc -Wall warnings
|
|
|
|
Fix the pkg-config files so that private libraries are specified in
|
|
"Libs.private:".
|
|
|
|
Fix the libext2fs.texinfo manual so it builds with modern versions of
|
|
texinfo.
|
|
|
|
Silence the makefile from showing the awk command used to build the
|
|
|
|
Clean up the badblocks group so to make it more portable and robust.
|
|
|
|
Avoid using predictable filenames in /tmp in blkid's regression test
|
|
suite. Also remove bashism's in the regression test script.
|
|
|
|
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)
|
|
|
|
Fix the blkid regression test suite to tolerate older versions of
|
|
mkswap that don't support the -U option.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
