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//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 " now properly shows the allocation status of the block . (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=" and "-o blocksize=". (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. (Addresses Sourceforge Bug: #2843248) 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. Fix some build failures caused by --disable-* configure options. Work around a bug in autoconf 2.64. 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-/dm/name; this is much faster than scanning for the device number in /dev/mapper. Fix blkid to prefer /dev/mapper/ 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. Fix a long-standing bug in e2fsck which would cause it to crash when replying journals for filesystems with block sizes greater than 8k. Update Catalan translation from the Translation Project. Fixed various Debian packaging issues --- see debian/changelog for details. (Addresses Debian Bugs: #503057, #502323, #511207) 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 , but can use #include 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 " 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.
