E2fsck will automatically +generate a UUID for those volumes that don't have them. + +Put in support for e2fsck to recognize HURD specific ext2 features --- +most notably, the translator block.

Previously e2fsck assumed that the inode was deleted (per 0.3c +ext2 kernel behavior) and offered to unlink the file. + +If e2fsck sets the clean bit, but nothing else, set the exit code +FSCK_NONDESTRUCT.

Otherwise, the inode would end up +getting marked as unused, which might cause loss of data later. + +Make the message issued by e2fsck when the superblock is corrupt less +confusing for users.

This +function is invoked by using the '-s' option to e2fsck. + +Debugfs's "dump" command has been enhanced so that it writes out the +exact size of the file so that the nulls at the end of the file are +eliminated. The command also accept a new "-p" option which will +attempt to preserve the ownership, permissions, and file +modification/access times. + +Debugfs has two new options, -f and -R. The -R option allows the user +to execute a single debugfs command from the command line. The -f +option allows the user to specify a "command file" containing debugfs +commands which will get executed. + +Dumpe2fs now pretty prints the check interval, instead of just +printing the check interval as a number of seconds. + +Fix bugs in debugfs: the params command when no filesystem is opened +no longer causes a core dump. It is now possible to unlink a file +when a pathname containing a '/' is specified. + +Tune2fs has a new -C option which sets the number of times the +filesystem has been mounted. + +Fix the chattr '-v' option so that it actually works. Chattr was +being buggy about the -v option parsing. + +Programmers' notes: +------------------- + +The directory lib/uuid contains a set of library routines to generate +DCE compatible UUIDs. + +Extended ext2fs_namei() to handle symbolic links.

(Users could usually get away with using tune2fs +on mounted filesystems before, but with the advent of ext3 and +journalling, it became important to make tune2fs was *really* safe for +use even when the filesystem being modified is mounted.) E2label is +now implemented by tune2fs using an argv[0] dispatch, so that e2label +is also now safe for use on mounted filesystems. + +Added a new program, e2image, which creates a backup of critical ext2 +filesystem data structures. The generated image file can be examined +using dumpe2fs and debugfs. In the future, e2fsck will be able to use +the image file to help recover very badly damaged filesystems. + +Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files +no longer cause e2fsck to bomb out. Also treat files > 2GB as being +large file when deciding whether or not the filesystem has large files. + +Fixed lsattr and chattr so that they work correctly on large files. +(Fixes Debian bug #72690.) + +Removed limitation in get_device_size() which imposed a one terabyte +filesystem limitation. (Most 2.2 kernels still have a signed int +problem which cause 1 TB block device limitation. Fortunately, the +kernel patches to fix this are much easier than fixing the 2TB +limitation in the kernel. :-) + +A max_mount_count of zero is now treated as if no mount count were +set. (Previously, no mount count was indicated by using -1, and a +mount count of zero caused e2fsck to always be run.) + +Mke2fs supports two new filesystem types largefile and largefile4. + +Mke2fs now adds some randomness in s_max_mount_count so that multiple +filesystems won't be all checked at the same time under normal +operations. + +Fixed bug in the progress bar printing code which could cause e2fsck +to core dump on an illegal filesystem. + +Fixed bug in fsck which could allow more than one instance of e2fsck +to be printing a progress bar. (Debian bug #65267) + +Fsck using a UUID or a LABEL specifier will work even if devfs is +compiled into the kernel and not mounted. If the pathnames in +/proc/partitions are incorrect, fsck will search /dev for the correct +device (using the new ext2fs_find_block_device library function). +Fsck now also checks the RAID devices first so that they are properly +found when they are in use. Support has also been added to support +additional IDE disks and the DAC 960 device names. (Debian bug #94159) + +Fixed a bug in fsck which caused it not deal properly with 16 +byte long filesystem labels. + +Fsck's -t option has been made a lot more flexible. The semantics for +what happens if a comma-separated list to fsck has been regularized, +and it is now possible to filter what filesystems will get checked +based what is in the filesystem's fstab entry's option field. (Debian +bug #89483.) + +The dumpe2fs program can now print out the group description +information in hex, and also prints the location of the superblock and +block group descriptor for those block groups that have them. + +Mke2fs now clears the ext2 superblock before it starts creating a +filesystem, so that the superblock magic number is only written if the +filesystem creation process successfully completes. + +The debugfs program's stat command now pretty-prints the blocks used +by an inode so that it's more compact and informative. + +The debugfs stats command now uses the same libe2p code (which is used +by dumpe2fs) to print the superblock header information. This is more +complete, and it avoids a bit of code duplication. + +Added a new debugfs command, set_super_value (ssv) which allows the +user to set arbitrary superblock fields. + +Debugfs was extended to support inode numbers in hex (by prefixing +them with 0x), and so that modify_inode can set the inode generation +number. Also, there is now a new function command called logdump +which will dump an ext3 journal. + +Fixed a bug in debugfs so that quitting out of the pager doesn't kill +debugfs. + +Debugfs's dump command now stops immediately upon reporting a disk +read error. (Fixed a bug in ext2fs_file_read library routine which +caused debugfs not to stop.) (Debian bug #79163) + +On systems with /proc/mounts (mainly Linux systems), /proc/mounts is +checked before /etc/mtab is used, since /proc/mounts is more likely to +be accurate. + +Added portability fixes for Solaris and Linux/ia64. + +Various manual pages were clarified and cleaned up.

This can lead to either a +crash or potentially a heap-based buffer overflow crash. No known +exploits exist, but main concern is where an untrusted user who +possesses privileged access in a guest Xen environment could corrupt a +filesystem which is then accessed by the pygrub program, running as +root in the dom0 host environment, thus allowing the untrusted user to +gain privileged access in the host OS.

This would cause a +array overrun leading to malloc pointer corruptions and segfaults. +Since we normally can very accurately predict how big the the dirinfo +array needs to be, this bug only got triggered on very badly corrupted +filesystems. + +Fix a bug in e2fsck which caused it to incorrectly salvage +directories when the last entry's rec_len is bogusly too big.

When revalidating +a partition where there is obsolete information in /etc/blkid.tab, we +end up freeing a the type tag without clearing dev->bid_type, causing +blkid_verify() to loop forever. (Addresses Debian Bug: #432052) + +The Turkish translation has a bug in it where it has the translation +of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at +@E, recursively, forever, until the stack fills up and e2fsck core +dumps. We fix this by making e2fsck stop @-expansions after a +recursive depth of 10, which is far more than we need. +(Addresses Sourceforge Bug: #1646081) + +Compile the default mke2fs.conf into mke2fs program. People are +getting surprised by mke2fs creating filesystems with different +defaults than earlier versions of mke2fs if mke2fs.conf is not +present.

This function sets the value +of the pseudo file "<default>". If the file "<default>" had +previously been passed to profile_init(), then def_string parameter +will be parsed and used as the profile information for the "<default>" +file. + +Fix mk_cmds's error reporting so that it is unambiguous that it is the +mk_cmds script which is generating the error. (Obviates Gentoo patch: +e2fsprogs-1.32-mk_cmds-cosmetic.patch) + +Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high +priority" environment variable that overrides all others, where as +LANG is the lowest priority environment variable. If LC_ALL is set, it +doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and +the all the rest are set. This will assure that the locale when +running the test suites is the "C" locale.

Fortunately bid_type isn't used much, and bid_label +and bid_uuid is only used by debugging code, so the impact of this bug +was very minor. + +Mke2fs will now store the RAID stride value when a filesystem is +created with a requested RAID stride, and then use it automatically in +resize2fs. + +Mke2fs has a sanity check added to make sure (inode_size * num_inodes) +isn't too big. In some cases Lustre users have tried specifying an +inode size of 4096 bytes, while keeping an inode ratio of one inode +per 4096 bytes. + +Improve sanity check in e2fsck's algorithm for finding a backup +superblock, so that it won't accidentally find a superblock that was +located in the journal, and then later reject it as being not a valid +backup superblock. + +Fix e2fsck get_size logic so that it will work with the Linux floppy +driver. The Linux floppy driver is a bit different from the other +block device drivers, in that if the device has been opened with +O_EXCL, it disallows another open(), even if the second open() does +not have the O_EXCL flag. (Addresses Debian Bug: #410569) + +Fix error checking of badblock's last-block and start-block arguments. +(Addresses Debian Bug: #416477) + +Fix e2fsck so that it doesn't overwrite the backup superblocks when +recovering a journal until the master superblock has been confirmed as +being sane. + +Change the blkid library to be much more paranoid about concluding +that a partition contains an NTFS filesystem, and fetch the UUID and +LABEL information from NTFS filesystems.

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.

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.

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.

(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.

(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.

(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.

(Addresses Launchpad Bug: #537483) + +In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if +it detected a badly aligned partition.

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 ".".

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.

(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 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 _().

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.

This false positive has been fixed. + +The e4defrag program has been fixed so it will no longer refuse with +filesystem with the 64-bit or the bigalloc feature enabled. + +The logsave program will print a much less scary message which could +lead users to believe something has gone very wrong with e2fsck exits +with a non-zero exit status (since this is normal after e2fsck has +automatically fixed a file system corruption during a preen +operation). (Addresses Debian Bug: #468821) + +When creating a file system which is larger than 16TB, the +resize_inode option must be disabled -- since the resize_inode simply +doesn't support reserving metadata block numbers which is larger than +32 bits.

It will now also do this if +the file size is specified explicitly. + +Fixed bugs associated with resize2fs and shrinking bigalloc file +systems. + +The e2fsck program will no longer try to add a UUID on a mounted file +system with checksums enabled, since this could leave the file system +checksums broken. + +Tune2fs will allow the removal of an external journal from file system +which is marked as needing the journal replayed when the force ("-f") +option is given twice.

(Previously, there were a few corner cases where +it might get things wrong in either direction.) + +E2fsck now correctly truncates or deallocates extent-mapped inodes on +the orphan list.

Otherwise, e2fsck -fy +after using mke2fs -S would leave the file system completely empty. + +Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also +honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has +installed an mke2fs binary using that name. + +The usage and help messages for the -G, -t and -T options in mke2fs +have been fixed. + +If e2fsck needs to use the backup group descriptors, the +ext2fs_open2() function clears the UNINIT bits to ensure all of the +inodes in the file systems get scanned. However, the code which reset +the UNINIT flags did not also recalculate the checksum, which produced +many spurious (and scary) e2fsck messages. This has been fixed by +resetting checksums when the UNINIT bits are cleared. + +Relax a check in e2fsck which required that the block bitmap to be +initialized when the inode bitmap is in use. This will allow us to +eventually eliminate code from the kernel which forcibly initialized +the block bitmap when the inode bitmap is first used, requiring an +extra journal credit and disk write. (Addresses Google Bug: #5944440) + +Make sure rdebugfs (which may be installed setuid or setgid disk) does +not honor environment variables if euid != uid or egid != gid. + +Debugfs's ncheck command has been optimized and now is much more +robust with faced with corrupted file systems.

Previously, it didn't, which generally made code +be less efficient, but it could cause bugs in ext2fs_link(), for +example, by causing it to insert multiple directory entries. + +Fixed an (harmless other than causing a compiler warning) use of an +uninitialized variable in e2fsck's MMP code. + + +E2fsprogs 1.42 (November 29, 2011) +================================== + +This release of e2fsprogs has support for file systems > 16TB. Online +resize requires kernel support which will hopefully be in Linux +version 3.2. Offline support is not yet available for > 16TB file +systems, but will be coming. + +This release of e2fsprogs has support for clustered allocation. This +reduces the number of block (now cluster) bitmaps by allocating and +deallocating space in contiguous power-of-2 collections of blocks, +which are called clustered. This is a file system level feature, +called 'bigalloc', which must be enabled when the file system is +initially formatted. It is not backwards compatible with older +kernels. + +Added support for the Multi-Mount Protection (MMP) feature. + +E2fsck more efficiently uses scratch files for really big file +systems. (This is a feature that has to be turned on explicitly; see +[scratch_files] in the e2fsck.conf man page.) + +Fix a bug in e2fsck where if the free blocks and inodes counts are +incorrect, e2fsck would fix them without printing an error message. +This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without +any explanation of what was fixed. + +E2fsck will no longer attempt to clone an extended attribute block in +pass1b handling if the file system does not support extended +attributes. + +E2fsck will be more careful accidentally asking the user to continue +if the file system is mounted, so that an escape sequence won't cause +a false positive. (Addresses Debian Bug: #619859) + +E2fsck now uses less cpu time in pass 5 when large portions of the +bitmaps are uninitialized. + +E2fsck will no longer segfault when a corrupted file system has a bad +extent, and removing it leads to a block needing to be deallocated. +(Addresses SourceForge Bug: #2971800) + +E2fsck will catch termination signals (segfaults, bus errors, sigfpe) +and print debugging information to make it easier to find potential +problems. + +E2fsck will check to see if the bad block inode looks insane, and will +skip trying to use if it certain fields which should be zero look +non-zero. This is to avoid a corrupted bad block inode causing e2fsck +to get confused and do more harm than good. + +If e2fsck modifies certain superblock fields which the kernel doesn't +look at, it will now mark the superblock as dirty without marking the +file system as changed. This avoids signaling the init scripts that +a reboot is necessary, since the kernel isn't going to look at those +fields, so it won't care if they have been changed. + +Fixed a bug in the libext2fs library (in the binary search routine of +the icount abstraction) that could (very, very rarely) cause e2fsck to +die in the middle of pass 1 or pass 2 processing. + +E2fsck will not try to do a discard operation if the -n option was +specified on the command line. + +E2fsck now supports an extended "discard" option which will cause +e2fsck to attempt discard all unused blocks after a full, successful +file system check. + +E2fsck will check for the bad block inode to make sure it looks sane +before trusting it, to avoid causing more harm than good to the file +system. + +E2fsck now returns additional status bits in its exit code if it +aborts early in the e2fsck run. + +E2fsck now correctly calculates the maximum file size in the case of +the huge_file file system feature enabled without extents. + +The mke2fs and e2fsck programs now tries to use the punch hole command +as a "discard" when operating on normal files. + +The e2image program now supports the qcow2 format, which is a more +efficient way of capturing file system dumps. + +Mke2fs now supports the [devices] stanza in mke2fs.conf which allows +per-device defaults to be specified in the configuration file. + +Mke2fs now supports the reserved_ratio relation in the [defaults] and +[fs_types] section in mke2fs.conf. + +Mke2fs now creates extent-mapped directories for the root and +lost+found directories. + +Mke2fs will skip zero'ing the journal if the extended option +"lazy_journal_init" is specified. This can save a lot of time, but it +does add a small amount of risk if the system crashes before the +journal is overwritten entirely once. It is especially useful for +testing. + +Mke2fs will now create file systems that enable user namespace +extended attributes and with time- and mount count-based file +system checks disabled. + +Mke2fs will not set a stride or strip size of one block based on block +device attributes obtained from sysfs. + +Mke2fs now displays a progress report during the discard process. + +Mke2fs now handles extreme file system parameters correctly which +previously caused the inodes per group to drop below 8, leading to a +segfault. (The inodes per group must be a multiple of 8, but the code +didn't correctly deal with an inodes per group count less than 8.) + +Mke2fs and tune2fs previously would give an error if the user tried +setting the stride and stripe-width parameters to zero; but this is +necessary to disable the stride and stripe-width settings. So allow +setting these superblock fields to zero. (Addresses Google Bug: +#4988557) + +Mke2fs now gives a warning if the auto-detected block size exceeds the +system's page size. + +If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which +is the default), mke2fs will now set the s_max_mnt_count superblock +field to -1, instead of 0. Kernels older then 3.0 will print a +spurious message on each mount then they see a s_max_mnt_count set to +0, which will annoy users.
