(Addresses Debian Bug: #452639) + +Updated Spanish and Catalan translations. + +Fixed various Debian packaging issues --- see debian/changelog for +details. (Addresses Debian Bugs: #483962, #483023) + +Add detection for ZFS volumes to the libblkid library. + +Fixed spelling mistakes, typos, and otherwise clarified man pages. +(Addresses Debian Bug: #486463) + +Programmer's notes: +------------------- + +Fix marginal C code in probe_lvm2() function to the blkid library more +portable for older compilers. + +Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473) + +Fix ext2fs_swap{16,32,64} functions so they can be used by external +applications on big-endian machines. (Addresses Debian Bug: #484879) + + +E2fsprogs 1.40.10 (May 21, 2008) +================================ + +When deciding whether or not to revalidate a blkid cache entry, if the +device's mtime is newer than the last time the cached entry was +validated, force a revalidation. + +Fix a potential data corruption bug in e2fsck in the journal replay. +The chances of this is happening is extremely remote, especially the +default data=ordered or data=writeback modes. However, if a block +which has been journalled starts with the first four bytes 0xc03b3998, +when e2fsck replays the journal, those four bytes will be replaced +with zero's. Fortunately, it is highly, highly unlikely for e2fsck +metadata to begin with those fatal 4 byte sequence, and unless +data=ordered mode is in use, data blocks are never journalled. + +Updated German, Dutch, Swedish, and Vietnamese translations. + +Programmer's notes: +------------------- + +Fixed various Debian packaging issues --- see debian/changelog for +details. + +Remove default sizes of types when cross compiling, since autoconf +2.50 can figure this out automatically now. + + +E2fsprogs 1.40.9 (April 27, 2008) +================================= + +SuSE's security team audited uuidd and came up with a few minor +issues. None of them are serious given that uuidd runs setuid as a +unprivileged user which has no special access other than libuuid +directory, but it's good to get them fixed. + +One additional fix in ext2fs_swap_inode_full() needed for resize2fs to +work correctly with in-inode extended attributes. + +Updated German, Czech, Dutch, French, Polish, Swedish, and Vietnamese +translations. + +Debugfs will avoid using a pager if the standard output is not a tty. + +Fix debugfs and tune2fs to correctly handle daylight savings time when +parsing a time string. + +Fixed spelling mistakes, typos, and otherwise clarified man pages. + +Fix fsck completion bars when multiple filesystems were being checked +in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug: +#203323, Addresses Sourceforge Bug: #1926023) + +Fix fsck so that progress information is sent back correctly when +multiple filesystems are being check and the output of fsck is being +redirected to a file descriptor. Also, include the device name (w/o +spaces) in the progress information sent back via a file descriptor. +(Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug: +#1926023) + +Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems. + +If logsave receives a SIGTERM or SIGINT signal, it will now pass that +signal to its child process. + +Fix mke2fs's creation of are resize inode when there is a non-standard +s_first_data_block setting. + +Fix bug in blkid when run by an unprivileged user; most devices were +not reported correctly. 9Addresses Launchpad Bug: #220275) + +Mke2fs will not allow the logically incorrect combination of +resize_inode and meta_bg, which had previously caused mke2fs to create +a corrupt filesystem. + +Fix fsck in German locales so that a 'j' means yes. +(Addresses Sourceforge Bug: #1947683) + + +Programmer's notes: +------------------- + +Fixed various Debian packaging issues --- see debian/changelog for +details. + +Update valgrind options in test_script to work with valgrind 3.2.3 + +Update texinfo.tex to a much newer version from the FSF. + +Remove bashism for configure script and from the lib/ss Makefile. +Addresses Sourceforge Bug: 1921969 + +Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt. + +Fix build system so that if texinfo is not installed, it won't print a +(harmless) error message. + + +E2fsprogs 1.40.8 (March 13, 2008) +================================= + +Fixed e2image -I so it works on image files which are larger than 2GB. + +Fixed e2fsck's handling of directory inodes with a corrupt size field. If +the size is larger than the number of blocks found in the inode, don't +try to allocate extra empty blocks at the end of the directory to make +up the difference; there's no point to doing that. In addition, if +the size is not a multiple of a blocksize, always fix it. + +E2fsck handled a pass 2 "should never happen error" by not giving +enough information and then core dumping. Unfortunately, it was all +too easy to trigger the "should never happen" situation if a +directory's inode size was not correct. This has been fixed, but +e2fsck has also been taught how to handle this situation more +gracefully, by simply removing the inode hash tree information, so +that it can be rebuilt again after e2fsck's pass 3. (Addresses +Launchpad Bug: #129395) + +Resize2fs had a bug resizing large inodes with extended attributes +that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed +completely on big-endian systems such as PowerPC. The bug should be +completely fixed now. Yay for regression test suites. (Addresses Red +Hat Bugzilla: #434893) + +Updated German, Czech, Dutch, Polish, Swedish, and Vietnamese +translations. Many thanks to Philipp Thomas from Novell for stepping +up to become the new German translation maintainer! (Addresses Debian +Bugs: #302512, #370247, #401092, #412882). + +When e2fsck is clearing a corrupt inode's HTREE directory information, +make it clear that it is just clearing the HTREE information, not the +entire inode. + +Fixed spelling mistakes, typos, and otherwise clarified man pages. + +Programmer's notes +------------------ + +Add new functions, ext2fs_dblist_get_last() and +ext2fs_dblist_drop_last(), which allows the caller to examine the last +directory block entry added to the list, and to drop if it necessary. + +Fixed a portability problem in libblkid with DJGPP. + +Fix an obvious typo in an "internal error" message in e2fsck. Thanks +to Philipp Thomas for pointing this out. + +If the info files are not built, change "make install" so it doesn't +fail with an error code. + + +E2fsprogs 1.40.7 (February 28, 2008) +==================================== + +Remove support for clearing the SPARSE_SUPER feature from tune2fs, and +depreciate the -s option, since it can result in filesystems which +e2fsck can't fix easily. There are very good reasons for wanting to +disable sparse_super; users who wants to turn off sparse_super can use +debugfs. (Addresses Sourceforge Bug: #1840286) + +Add missing options to mke2fs's usage message. (Addresses Sourceforge +Bug: #1751393) + +Fix bug in resize2fs when large (greater than 128 byte) inodes are +moved when a filesystem is shrunk; it was only moving the first 128 +bytes, so extended attributes were not getting moved. (Addresses Red +Hat Bugzilla: #434893) + +E2fsck now prints an explicit message when the bad block inode is +updated, to avoid confusion about why the filesystem was modified. +(Addresses Sourceforge Bug: #756460) + +Allow mke2fs and tune2fs manipulate the large_file feature. +Previously we just let the kernel and e2fsck do this automatically, +but e2fsck will no longer automatically clear the large_file feature. +It still isn't really necessary to worry about this feature flag +explicitly, but some users seem to care. (Addresses Red Hat Bugzilla: +#258381) + +Suppress message about an old-style fstab if the fstab file is empty. +(Addresses Debian Bug: #468176) + +Fix (really minor) bug in debugfs's find_free_block so it avoids +reporting a free block more than once if there are too few free blocks +in the filesystem. (Addresses Sourceforge Bug: #1096315) + +Change e2fsck to no longer clear the LARGE_FILES feature flag +automatically, when there are no more > 2GB files in the filesystem. +It's been almost a decade since there have been kernels that don't +support this flag, and e2fsck clears it quietly without telling the +user why the filesystem has been changed. + +Fix bug which could cause libblkid to seg fault if a device mapper +volume disappears while it is being probed. (Addresses RedHat +Bugzilla: #433857) + +Enhance e2fsck's reporting of unsupported filesystem feature flags. +(Addresses Sourceforge Feature Request: #1175808) + +Fix option syntax in dumpe2fs for explicit superblock and blocksize +parameters. What was currently documented in the man page has been +broken for some time, due to getopt() implementation changes. The +option syntax has been changed to one which is can be more portable +supported and which is consistent with the format for extended options +in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994) + +Add support to tune2fs to clear the resize_inode feature. This +requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816) + +Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat +Bugzilla: #409321) + +Add support for setting RAID stride and stripe-width via mke2fs and +tune2fs. Teach dumpe2fs to print the RAID parameters. + +Add support for setting new superblock fields to debugfs's +set_super_value. + +Add support for printing "mostly-printable" extended attributes in +Debugfs. + +Add support for the -M option to fsck, which causes it to ignore +mounted filesystem. + +Fix uuidd so that it creates the pid file with the correct pid number. +(Addresses Sourceforge Bug: #1893244) + +Fix various gcc -Wall warnings. + +Update Czech, Dutch, Polish, Swedish, and Vietnamese translations + +Fixed spelling mistakes, typos, and otherwise clarified man pages. +(Addresses Sourceforge Patch: #1399325) + + +Programmer's notes: +------------------- + +Fixed various Debian packaging issues --- see debian/changelog for +details. (Addresses Debian Bug: #466929) + +Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a +partially filled-in filesystem object on an error, so that e2fsck can +print more intelligent error messages. + +Add a new function e2p_edit_feature2() which allows the caller to +specify which feature flags are OK to set or clear, and which returns +more specific information about feature flags which are not allowed to +be set/cleared. + +Set the C locale in the test_script driver since it uses [A-Za-z]. +(Addresses Sourceforge Bug: #1890526) + +Use fcntl locking instead of lockf in libuuid since Cygwin doesn't +support lockf(). + +Change configure.in to avoid using the 'dc' command unless it is +absolutely needed. (i.e., when using parsing a WIP-style version +number) (Addresses Sourceforge Bug: #1893024) + +Add portability checks to support compilation under DJGPP. + +Update to the latest samba tdb code before the LGPLv3 change, which +fixes a realloc() leak on failure. + +Fix memory leak in ext2fs_alloc_block(). + +Fix makefile dependency issues for various install targets. +(Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456) + +Improve descriptions for the r_move_itable and r_resize_inode tests. + + +E2fsprogs 1.40.6 (February 9, 2008) +=================================== + +Add support for returning labels for UDF filesystems in the blkid +library. + +Fix bug in the blkid library where cached filesystems was not being +flushed when opening USB devices returned the error ENOMEDIUM. +(Addresses Debian Bug: #463787) + +Added logic to the blkid library to automatically choose whether a +filesystem should be mounted as ext4 or ext4dev, as appropriate. + +Allow tune2fs to set and clear the test_fs flag on ext4 filesystems. + +Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been +configured with --enable-jbd-debug. + +Document the BLKID_FILE environment variable in the libblkid man page + +Programmer's Notes: +------------------- + +Update e2fsprogs translation template and Vietnamese and Czech translations + +Fixed various Debian packaging issues --- see debian/changelog for +details. (Addresses Debian Bugs: #436058) + +Don't try to create $DESTDIR/etc/init.d as part of make install as we +don't install the init.d script (and it's not the recommended way to +start uuidd anyway). (Addresses Sourceforge Bug: #1885085) + +Use thread local storage to fix a theoretical race condition if two +threads try to format an unknown error code at the same time in the +com_err library. + + +E2fsprogs 1.40.5 (January 27, 2008) +=================================== + +Fix a potential overflow big in e2image if the device name is too +long. + +Mke2fs will now create new filesystems with 256 byte inodes and the +ext_attr feature flag by default. This allows for much better future +compatibility with ext4 and speeds up extended attributes even on ext3 +filesystems. + +Teach e2fsck to ignore certain "safe" filesystem features which are +set automatically by the kernel. Having the kernel set features +automagically behind the user's back is a bad idea, and we should try +to break the kernel of this habit, especially for the newer ext4 +feature flags. But for now, we will try to avoid needless full checks +which can annoy users who are doing fresh installs. + +Add support in tune2fs and mke2fs for making a filesystem as being "ok +to be used with test kernel code". This will be needed for using test +filesystems with the latest ext4 kernel code. + +Change e2fsck -fD so that it sorts non-htree directories by inode +numbers instead of by name, since that optimizes performances much +more significantly. (Addresses-Sourceforge-Feature-Request: #532439) + +If e2image fills the disk, fix it so it exits right away instead of +spewing large numbers of error messages. +(Addresses-Sourceforge-Feature-Request: #606508) + +If ftruncate64() is not available for resize2fs, let it use ftrucate() +instead, but have it check to see if the size would get truncated, and +skip calling ftruncate in that case. + +Add support for detecting HFS+ filesystems in the blkid library. + +Add support in the blkid library for ext4/ext4dev filesystems. + +Fix a bug in blkid where it could die on a floating point exception +when presented with a corrupt reiserfs image. + +Fix blkid's handling of ntfs UUID's so that leading zeros are printed +such that UUID string is a fixed length. + +Add sample python bindings for the uuid library to the contrib +directory. (Addresses-Sourceforge-Patches: #778817) + +Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it +will work with large files. (Addresses Sourceforge Feature Request: +#1257500 and Sourceforge Support Request: #1253511) + +Allow the debugfs 'undel' command to undelete an inode without linking +it to a specific destination directory, since this might require +allocating blocks that could overwrite some yet-to-be-recovered +deleted files. (Addresses-Sourceforge-Feature-Request: #967141) + +Update Swedish translation from the Translation Project. + +Programmer's Notes: +------------------- + +Fix configure handling of --sbindir (which should rarely be used, but +someone did complain, so let's fix it). (Addresses Sourceforge Bug: +#498381) + +Updated e2fsprogs.spec file to include a new uuidd package + +Use pkg-config to determine where to find the devmapper library so we +can find out where it is located on different distributions. + +Fix Makefile race so that "make -j3 distclean" works correctly + +Fix portability problems on non-Linux/non-Hurd/non-Masix systems, +especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633, +#1819034, #1863819) + +Fixed spelling mistakes, typos, and otherwise clarified man pages. + +Fixed various Debian packaging issues --- see debian/changelog for +details. (Addresses Debian Bugs: #459403, #459475, #459614) + +Remove the --enable-dynamic-static configure option, and build e2fsck +dynamically by default. If the user wants e2fsck.static, he/she will +need to build it via "make -C e2fsck e2fsck.static" + +Fix various build warnings due to missing prototypes. +(Addresses Sourceforge Patch: #1861663, #1861659) + + +E2fsprogs 1.40.4 (December 31, 2007) +==================================== + +Improve time-based UUID generation. A new daemon uuidd, is started +automatically by libuuid if necessary. This daemon is setuid to allow +updates to /var/lib/libuuid, so the clock sequence number can be +stored and so if the clock is set backwards, it can be detected. +(Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla: +#233471) + +Filter out the NEEDS_RECOVERY feature flag when writing out the backup +superblocks. This avoids e2fsck from concluding that a full +filesystem check is required before backing up the superblock due to +changes in the feature flags. (Addresses Debian Bug: #454926) + +Fix fsck to only treat the '#' character as a comment at the beginning +of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem +will cause fsck to issue an bogus warning message. +(Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147) + +Format control characters and characters with the high eighth bit set +when printing the contents of the blkid cache, to prevent filesystems +with garbage labels from sending escape sequences to the user's screen +that might, for example place it in graphics mode. (Addresses Ubuntu +Bug: #78087) + +Fix sign-extension problem on 64-bit systems in in the com_err +library. (Addresses Sourceforge Bug: #1809658) + +Avoid division by zero error when probing an invalid FAT filesystem in +the blkid library. (Addresses Sourceforge Bug: #1831627) + +Update Dutch, Polish, and Vietnamese translations from the Translation +Project. Remove the Rwandan translation upon advice of the +Translation Project. + +Programmer's Notes: +------------------- + +Fix the libss "make check" regression test so that it works if the +current directory is not in the user's path or if the libss shared +library is not installed. (Addresses Sourceforge Bug: #1848974) + +Fixed spelling mistakes, typos, and otherwise clarified man pages. +(Addresses Debian Bugs: #444883, #441872) + +Fixed various Debian packaging issues --- see debian/changelog for +details. (Addresses Debian Bugs: #437720, #451172, #458017) + +Fix build failure on non-Linux/non-Hurd/non-Masix systems. +(Addresses Sourceforge Bug: #1859778) + +Fix Hurd portability issues. (Addresses Debian Bug: #437720) + + +E2fsprogs 1.40.3 (December 5, 2007) +=================================== + +Fix a potential security vulnerability where an untrusted filesystem +can be corrupted in such a way that a program using libext2fs will +allocate a buffer which is far too small. 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. Thanks to the McAfee AVERT +Research group for reporting this issue. (Addresses CVE-2007-5497.) + +Fix heuristics in blkid which could cause a disk without partitions to +be incorrectly skipped when a loopback device is present. (Addresses +Red Hat Bugzilla #400321.) + +Fix e2image so that in raw mode it does not create an image file which +is one byte too large. + +Change mke2fs's usage message so it recommends the preferred -E option +instead of the deprecated -R option. + +Enhance the blkid library so it will recognize squashfs filesystems. +(Addresses Red Hat Bugzilla #305151.) + +Enhance e2fsck so it will force the backup superblocks to be backed up +if the filesystem is consistent and key constants have been changed +(i.e., by an on-line resize) or by e2fsck in the course of its +operations. + +Enhance blkid's detection of FAT filesystems; so that USB disks with +only a single bootable partition will not get missed. + +E2fsck will no longer mark a filesystem as invalid if it has time +errors (i.e., if superblock mount time or last write time is in the +future) and the user refuses to fix the problem. + +The Ubuntu init scripts don't properly set the system time correctly +from hardware clock if the hardware clock is configured to tick local +time instead of GMT time. Work around this as best as we can by +providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can +be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu +Bug #131201.) + +Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red +Hat Bugzilla #151533.) + +Fix e2fsck so that if the superblock is corrupt, but still looks +vaguely like an ext2/3/4 superblock, that it automatically tries to +fall back to the backup superblock, instead of failing with a hard +error. + +Make the e2fsprogs program more robust so that they will not crash +when opening a corrupt filesystem where s_inode_size is zero. + +Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric +arguments are detected as such and the parse error is reported to the +user. (Addresses Debian Bug #435381.) + +Change e2fsck so it will not complain if a file has blocks reallocated +up to the next multiple of a system's page size. + +Fix bug in ext2fs_check_desc() which will cause e2fsck to complain +about (valid) filesystems where the inode table extends to the last +block of the block group. (Addresses Red Hat Bugzilla #214765.) + +Fix a bug in ext2fs_initialize() which causes mke2fs to fail while +allocating inode tables for some relatively rare odd disk sizes. +(Addresses Red Hat Bugzilla #241767.) + +Add Catalan translation and update Dutch and Swedish translations +from the Translation Project. + +Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We +still had an issue when trying to figure out whether we need to +byte-swap fast symlinks that contained extended attributes. + +Fixed spelling mistakes, typos, and otherwise clarified man pages. +(Addresses SourceForge Bug #1821333.) + + +Programmer's Notes: +------------------- + +Fix mke2fs tests to avoid needing any significant ^M (CR) characters + +Add "make check" to the RPM spec file + +Fix "make install" and 'make uninstall" in misc/Makefile.in so that it +works correctly when the prefix is not the root directory. + +Fix the resize2fs tests, r_move_itable and r_resize_inode, so they +clean up after themselves by deleting the test.img temporary file +after completing the test. + +Fixed a corner case bug ext2fs_unlink() when trying to delete the +first directory entry in a directory block and the last directory +entry in the previous directory block is not in use. Fortunately +ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in +places where it is extremely unlikely to run into this corner case. + +Fix missing dependency which would cause parallel builds to fail. +(Addresses Sourceforge Bug #1842331.) + +Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c +calling open(O_CREATE) with a missing mode parameter. + +Fix the test_ss.c in lib/ss so it can be used as an example +application program for the library as well as a regression test +suite. + +Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes +are properly passed back up through the call stack. + +E2fsprogs 1.40.2 (July 12, 2007) +================================ + +A recent change to e2fsck_add_dir_info() to use tdb files to check +filesystems with a very large number of filesystems had a typo which +caused us to resize the wrong data structure. 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. This +resulted in a nonsense filesystem corruption to be reported, and +required a second run of e2fsck to fully fix up the directory. + +Update tune2fs man page to include more discussion of reserved blocks +(Addresses Launchpad bug #47817) + +Update Turkish, Polish, Dutch, and Vietnamese PO files from the +Translation Project + + +E2fsprogs 1.40.1 (July 7, 2007) +=============================== + +Fix bug which could cause libblkid to loop forever. 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. So we now create a built in version of mke2fs.conf file +which is used by mke2fs if the /etc/mke2fs.conf is not present. +(Addresses SourceforgeBug: #1745818) + +Improve the config/parse_types.sh helper script. Fix a potential +security problem if e2fsprogs is built as root (as Gentoo does!). In +addition fix the script and how it is called from the configure script +so that it does the right thing when cross-compiling. (Fixes Gentoo +bug: #146903) + +Update Vietnamese, French, and Dutch PO files from the Translation +Project. Also created a new e2fsprogs.pot file for translator. + +Fix bogus strip permission errors when building under Debian. When +building the e2fsprogs dpkg's, the dh_strip command emits a large +number of error messages caused by the permissions not being right. +So run dh_fixperms before running dh_strip. + +Programmer's Notes: +------------------- + +Add new function: profile_set_default(). 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. (Obviates Gentoo patch: +e2fsprogs-1.38-tests-locale.patch) + + +E2fsprogs 1.40 (June 29, 2007) +============================== + +Fix divide by zero error in blkid's NTFS probing logic. + +Add new blkid -g option which causes the blkid cache to be garbage +collected. + +Fix a bug in libblkid which could cause the internal field bid_type to +become corrupted. 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. (Addresses Launchpad Bug: +#110138) + +Factor out the code which sets the default journal size and move it +into libext2fs. + +Enhance e2fsck so it will recreate the ext3 journal if the original +journal inode was cleared to due it being corrupt after finishing the +filesystem check. + +Fix e2fsck so that it updates the journal inode if it is corrupted and +the backup journal information from the superblock was successfully +used to recover the filesystem. + +Fix e2fsck so that it checks all of the blocks in the journal inode +for validity. The original code only checked the direct blocks to +make sure the journal inode was sane. Unfortunately, if some or all +of the indirect or doubly indirect blocks were corrupted, this would +not be caught. + +Add support in blkid to detect LUKS encrypted partitions. + +Add extra sanity checks for extended attributes in the case where the +size is zero but the offset is very large. + +Fix byte-swapping issues for large inodes in ext2fs_read_inode_full() +and ext2fs_get_next_inode_full(). + +Clarify the copyright licenses used by the various libraries in +the top-level COPYING file (Red Hat Bugzilla: 166058) + +Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane. + +Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's. + +Remove check in e2fsck which requires EA's in inodes to be sorted; +they don't need to be sorted, and e2fsck was previously wrongly +clearing unsorted EA's stored in the inode structure. + +Allow mke2fs or tune2fs to create a substantially larger journal (up +to 10,240,000 blocks). + +Fix MD superblock detection, and make sure the correct UUID is +reported from the MD superblock. + +Fix a signed vs. unsigned bug in debugfs. + +Enhance debugfs's date parser so that it accepts integer values. + +Fix e2fsck's pass1c accounting so it doesn't terminate too early if a +file with multiply claimed blocks is hard linked. or not at all if the +root directory contains shared blocks + +Enhance debugfs so it can modify the block group descriptors using the +command set_block_group_descriptor. + +Improve e2fsck's reporting of I/O errors so it's clearer what it was +trying to do when an error happens + +Fix a bug in in how e2fsprogs byte swaps inodes containing fast +symlinks that have extended attributes.

(Addresses Lustre Bug: #11645) + +Enhance e2fsck to recover directories whose modes field were corrupted +to look like special files. This is probably only useful in +artificial test cases, but it will be useful if we ever do the "inodes +in directory" idea for ext4. + +Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug: +#412614) + +Fix resize2fs parsing of size parameter (in sector units). This was +actually a bug in libe2p's parse_num_blocks() function. When handling +the 's' suffix, it was ignoring the blocksize information passed in +from the caller and always interpreting the number in terms of a 1k +blocksize. (Addresses Debian Bug: #408298) + +There was a floating point precision error which could cause e2fsck to +loop forever on really big filesystems with a large inode count. +(Addresses Debian Bug: #411838) + +Fix memory leak in ext2fs_write_new_inode() + +Add support for using a scratch files directory to reduce e2fsck's +memory utilization on really big filesystems. This uses the TDB +library.

Omit by default printing superblocks that are likely +found in located in an ext3 journal unless an explicit -j option is +given. + +Updated Spanish, French and Dutch translations and added Catalan +translation. (Addresses Debian bug: #411562) + +Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when +determining a partition's size, since binary searching to determine +the device doesn't work on FreeBSD. + +Documentation about UUID's is available in enough places, and it's +awkward to deal with debian-legal's insanities. So I'm caving in the +"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we +don't have do the dfsg tarball. Also remove the rule that only tried +to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch +e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107) + +Fix the info-dir line so that the menu name does not contain a .info +prefix. First of all, it's ugly, secondly, it causes the install-info +command to fail to remove the com_err info file from the +/usr/share/info/dir file when the comerr-dev package is removed and +purged.

(Addresses SourceForge Bug: #1532177) + +Added the 64-bit byte swapping function ext2fs_swab64(). + +Added two new helper functions to prevent 2**31/2**32-1 overflow +problems: ext2fs_div_ceil() and e2p_percent(). + +Create new ext2fs library inline functions ext2fs_group_first_block() +and ext2fs_group_last_block() in order to calculate the starting and +ending blocks in a block group. + +Create the generated files read-only to remind developers not to edit them. + +Add support for autoconf 2.60 (with backwards compatibility for older +versions of autoconf). + +Added an "make rpm" target to top-level Makefile + +Added various FreeBSD portability fixes. + +Exclude mercurial files from the RPM build tree to speed up copy/build. + +Use root_sysconfdir to define the locations of mke2fs.conf and +e2fsck.conf instead of using a hard-coded /etc pathname. + +Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times. + +Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files. + +If diff -u is supported, use it to report test failures. + +Updates/improvements to RPM spec file + +Add on-disk format definitions for the following new features: +EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM, +EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT, +EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE + +Add a new make target "checked-failed" in the tests directory which +reruns any failed tests + +Update draft-leach-uuids-guids-01.txt with rfc4122.txt + +Fix miscellaneous bugs reported by Coverity: Dead code, potential nul +pointer dereferences, memory leaks, etc. None were security-critical +problems. + +Fix up usage and decrement error messages in the test_icount program + +Add debugging code to the com_err library; if the environment variable +COMERR_DEBUG is set to 1, print out debugging messages as error tables +are added and removed from the com_err library. If the +COMERR_DEBUG_FILE environment variable is set (and the process is not +setuid) the debugging messages may be redirected to a file. + +Change all of the e2fsprogs programs to use the newer add_error_table() +and remove_error_table() interfaces instead of the much older +initialize_*_error_table() function. + +Add TDB support into the ext2fs library. This allows us to have a +guaranteed library we can count on always being present so we can +store data in an on-disk database. + +Add support for using TDB to store the icount data, so we don't run out +of memory when checking really large filesystems. + +Change the regression test suite so that it skips empty test directories. + +Define the l_i_iversion field in ext2_inode.

In +general, only e2fsck (after the filesystem is clean), tune2fs, and +resize2fs should change the backup superblocks by default.
