When revalidating +a partition where there is obsolete information in /etc/blkid.tab, we +end up freeing a the type tag without clearing dev-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 "". If the file "" had +previously been passed to profile_init(), then def_string parameter +will be parsed and used as the profile information for the "" +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 priorty 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 Red Hat Bugzilla: +#232663 and LTC Bugzilla: #27634) + +Fix potential file descriptor leak in ext2fs_get_device_size() in an +error case. + +Add libreadline.so.5 support to libss. + +Impove badblocks -n/-w exclusive usage message. + +Fix dump_unused segfault in debugfs when a filesystem is not open + +Fix memory leak in blkid library. (Addresses Debian Bug: #413661) + +Allow the debugfs lcd command to work w/o a filesystem being open. +(Addresses LTC Bugzilla #27513) + +Fix e2fsck to clear i_size for special devices with a bogus i_blocks +field on the first pass. + +Fix e2fsck to set the file type of the '..' entry when connecting +a directory to lost+found. (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 +emory utilization on really big filesystems. This uses the TDB +library. See the [scratch_files] section of the e2fsck.conf man page +for more details. + +Fixed type-punning bug which caused dumpe2fs to crash on the Arm +platform (Addresses Debian Bug: #397044) + +Add explanatory message to badblocks that -n and -w are mutually exclusive +(Addresses Debian Bug: #371869) + +Allow debugfs and dumpe2fs to support fs features under development. + +Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to +ext2fs_open() , which allows application to open filesystes with features +which are currently only partially supported by e2fsprogs. + +Allow unix_io to support offsets greater than 2G (Addresses +SourceForge Bug: #1547922) + +Fixed overflow and signed/unsigned problems caused by the number of +blocks or inodes exceeding 2**31 or being close to 2**32-1. + +Add support for unsigned directory hash calculations with hints in the +superblock to fix cross-architectural portability for htree +directories with filenames where the high 8th bit is set. (Addresses +Debian: #389772) + +Fix resize2fs so that it gives user-intelligible error messages if the +filesystem or the kernel does not support on-line resizing. +(Addresses Debian Bug: #380548) + +Require mke2fs -F -F for really dangerous operations, since -F is +needed for less dangerous operations such as creating filesystems +images in regular files, or creating filesystems on whole block +devices. These relatively innocuous usages should NOT be confused +with running mke2fs on an apparently-mounted or in-use filesystem. + +Allow the default inode size to be specified into the mke2fs.conf +file. + +Make the smallest default journal size is big enough so that on-line +resizing should always work. + +Fix silly spelling error in e2fsck. (Addresses SourceForge bug: +#1531372) + +Fix debugfs coredump when lsdel is run without an open filesystem +(Addresses Debian Bug: #378335) + +Fix debugfs display bug us that bytes that have the high bit set are +displayed as "ec" instead of "ffffffec". + +Add support in lsattr so it will display the EXT4_EXTENTS_FL flag. + +Device mapper scanning wasn't working in the blkid library because the +pathnames had an extra "/dev" when they were being probed. + +Add GFS/GFS2 support to the blkid library. + +Fix blkid support of empty FAT filesystem labels. + +Avoid recursing forever (or for a long time) when the blkid library +searches for a device and there are symlinks to directories in /dev. + +Avoid unaligned halfword access in blkid when accessing FAT +superblocks, as this will cause Sparc/Solaris systems to throw a +SIGBUS error. + +The latest devmapper libraries requires pthreads, add -lpthreads to +the static link libraries for e2fsck.static if devmapper is enabled. +(Addresses Debian bug: #388718) + +Improve the (non-installed, for experts only) findsuper program by +printing the uuid and label from the superblocks, as well as the +starting and ending offsets of the filesystem given the information in +the superblock. Omit by default printing superblocks that are likely +found in located in an ext3 journal unless an explicit -j option is +given. + +Updated French and Dutch translations and added Vietnamese translation. + +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 Debian Bug: #401711) + +Fixed spelling mistakes, typos, and otherwise clarified man pages. +(Addresses Debian Bug: #369761, #373004, #379695) + +Fixed various Debian packaging issues --- see debian/changelog for +details. (Addresses Debian Bugs #389554, #390664, #413208, #419605, +#408352, #415560, #399155) + + +Programmer's notes: +------------------- + +E2fsck now supports the %It expansion when printing a problem report. +It will print the type of the inode in the problem context. + +Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet +(Addresses Sourceforge Bug: #1565561) + +Remove unused variables and other lint/gcc -Wall cleanups + +Add check to ext2fs_get_device_size() so it will return EFBIG for for +filesystems contained in regular files where the filesystem image size +is returned by stat64(). + +Set local environment variables to C so mk_cmds and compile_et always +work. (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-criticial +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. The l_i_version field is +now defined from the old l_i_reserved1 field in the ext2 inode. This +field will be used to store high 32 bits of the 64-bit inode version +number. + +Add Makefile production rule for e2fsprogs.spec in case it gets +deleted. + +Add new function profile_get_uint() to allow for a clean way to fetch +unsigned integers from the context. + +Add test to make sure the ext2 superblock structure is 1024 bytes. + +Fix typo in name of f_dup4 regression test + +Add new function blkid_gc_cache() which performs a garbage collection +pass on the /etc/blkid.tab file. + +The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In +general, only e2fsck (after the filesystem is clean), tune2fs, and +resize2fs should change the backup superblocks by default. Most +callers of ext2fs_open() should not be touching any superblock fields +which require the backups to be touched. + +Add new function to libext2fs, ext2fs_default_journal_size(), which +returns the default journal size. + + +E2fsprogs 1.39 (May 29, 2006) +============================= + +Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems +between 2**31 and 2**32 blocks. + +Change mke2fs to use /etc/mke2fs.conf as a configuration file to +configure the filesystem features, blocksize, and inode_ratio for +different filesystem types. + +Mke2fs will now create filesystems hash trees and on-line resizing +enabled by default, based on the new /etc/mke2fs.conf file. + +The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the +filesystem device node in exclusive mode to prevent accidents by +system administrators. In the case of resize2fs and mke2fs, it will +only use exclusive mode if the filesystem is not mounted. + +Fixed a bug in mke2fs which caused it to to fail when creating the +resize inode for large filesystems. (Addresses Debian Bug #346580) + +When allocating space for the RAID filesystems with the stride +parameter, mke2fs will now place each portion of the group's inode +table right up after the superblock (if present) in order to minimize +fragmentation of the freespace. + +Speed up mke2fs and e2fsck by writing inode and block bitmaps more +efficiently by writing the inode and block bitmaps in one pass, thus +reducing the number of disk seeks required. + +Add support for on-line resizing to resize2fs. + +Fix blkid library so that logic to determine whether or not a device's +cached information in /etc/blkid.tab needs to be verified or not +doesn't get confused by a system clock which is insane (for example, +if the battery is dead on a Macintosh running PPC Linux. (Addresses +Red Hat Bug: #182188) + +The blkid library will now store the UUID of the external journal used +by ext3 filesystems, so that in the future, the userspace mount binary +can use this to find the location of the external journal and pass +this information to the kernel. + +E2fsck will now consult a configuration file, /etc/e2fsck.conf to +control how various options should be handled. See the e2fsck.conf +man page for more details. (Addresses Debian Bug: #150295) + +E2fsck now prints an explanatory message when delaying a filesystem +check when the system is running on battery. (Addresses Debian Bug: +#350306) + +E2fsck will detect if the superblock's last mount field or last write +field is in the future, and offer to fix if so. (Addresses Debian Bug +#327580) These problems will be fixed automatically in preen mode +since Debian's boot sequence bogusly doesn't set the time correctly +until potentially very late in the bootup process, and this can cause +false positives which will cause users' systems to fail to boot. +(Addresses Debian Bugs #343662 and #343645) + +E2fsck now checks to see if the superblock hint for the location of +the external journal is incorrect, and if so, offer to update it. +(Addresses Debian Bug: #355644) + +Fix e2fsck from segfaulting on disconnected inodes that contain one or +more extended attributes. (Addresses Debian Bug: #316736, #318463) + +E2fsck will stop and print a warning if the user tries running a +read/write badblocks test on a read-only mounted root filesystem. + +Fix a memory leak in e2fsck's error paths. (Thanks to Michael +C. Thompson for pointing these out; they were originally found using +Coverity.) + +When resizing a file containing a filesystem, resize2fs will expand or +truncate a file as necessary. (Addresses Debian Bug: #271607) + +Resize2fs will now automatically determine the RAID stride parameter that +had been used to create the filesystem, and use that for newly created +block groups. The RAID stride parameter may also be manually specified +on the command line using the new -S option to resize2fs. + +Fix mke2fs so that it correctly creates external journals on +big-endian machines (such as a S/390). + +Fix a bug in the e2p library which could cause dumpe2fs to (rarely) +fail to print out the journal or hash seed UUID. (Thanks to Guillaume +Chambraud for pointing this out.) + +Dumpe2fs will now print the size of the journal (if present). + +Fix debugfs's set_inode_field command so it can properly set the frag, +fsize, uid_high, gid_high, and author fields in the inode instead of +silently failing, and so that setting the i_size actually sets i_size +correctly. + +Add a new debugfs command, set_current_time, which sets fs->now so +that regression test suites can repeatedly modify the filesystem's +last_write fields. + +Fix a bug in debugfs's icheck which would incorrectly report the owner +of an extended attribute block. + +Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a +print a usage message when an illegal option character is given. + +Fix debugfs's dump_unsued command on filesystems with a 64k blocksize +so it won't core dump.

(Addresses Debian Bug: #345832) + +Add support for the reiser4 and software suspend partitions to the +blkid library. Also add support for extract the label from iso9660 +filesystems. + +Fix a compile_et bug which miscount the number of error messages if +continuations are used in the .et file. + +Add extra sanity checks to protect users from unusual cirucmstances +where /etc/mtab may not be sane, by checking to see if the device is +reported busy (works on Linux 2.6) kernels.

It allows an ext2/ext3 developer to +create very large filesystems using sparse files where most of the +block groups are not initialized and so do not require much disk +space. Eventually it could be used as a way of speeding up mke2fs and +e2fsck for large filesystem, but that would be best done by adding an +RO_COMPAT extension to the filesystem to allow the inode table to be +lazily initialized on a per-block basis, instead of being entirely +initialized or entirely unused on a per-blockgroup basis. + +Fix backwards compatibility so e2fsprogs will better compile on Linux +2.0.35 systems. + +Make test scripts more robust against locale-related environment variables + +Fix type warning problem with sizeof() in ext2fs_open2(). + +Fix type warning problem with time_t in debugfs. + + +E2fsprogs 1.38 (June 30, 2005) +============================== + +Fix blkid's test programs (built with "make check") compile correctly +even without "configure --enable-blkid-debug". + +Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict +type aliasing rules on newer gcc compilers.

Negative bit +numbers were never allowed (and didn't make any sense), so this should +be a safe change. This is needed to allow safe use of block numbers +greater than or equal to 2**31. + +The compile_et program will avoid recreating generated foo_err.c and +foo_err.h files if no changes are necessary. The compile_et program +will also atomically replace these files to avoid a potential parallel +build race problem on SMP systems.

This can take place when +mke2fs creates the root and lost+found directory, when e2fsck creates +a new root inode or a new lost+found directory, and when the user uses +the debugfs write, mknod, or mkdir commands. Otherwise, the newly +create inode could inherit garbage (or old EA information) from a +previously deleted inode. + +Fixed a bug in e2fsck so it would notice if a file with an extended +attribute block was exactly 2**32 blocks, such that i_blocks wrapped +to zero. + +Added support to filefrag to detect files which are using the new +experimental file extents format, and use the non-ext2 algorithm in +that case. Fixed a bug to avoid reporting a false discontinuity if +there is one or more unallocated blocks at the beginning of a file. + +Duplicated a check for noticing whether or not the number of blocks +(given a certain blocksize) is greater than 2**32 when the +BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This +allows mke2fs to automatically use a larger blocksize when creating a +filesystem on a very large device when run on systems that do not +support BLKGETSIZE64. + +Fix the I18N build which was broken in e2fsprogs 1.36 because the +build system had been switched to treat the .gmo files as shipped +files (for backwards compatibility with systems that have older GNU +I18N tools installed), but the gen_tarball.in script was still +removing the .gmo files from the official source distribution. + +Fixed various Debian packaging issues --- see debian/changelog for +details. (Addresses Debian Bugs ##296769, #299341) + +Programmer's notes: +------------------- + +Added new functions to the e2p library which convert between a string +and os_type: e2p_os2string() and e2p_string2os(), and used them to +make the generated binaries more compact. + +Fixed a compile-time error on Darwin systems. + +Cleaned up the lib/ext2fs Makefile slightly. + + +E2fsprogs 1.36 (February 4, 2005) +================================= + +All of the patches that were applied to Fedore Core 3's +e2fsprogs-1.35-11.2 have been integrated, although sometimes with a +lot of bug fixes first. Users of Fedora Core 3 are strongly +encouraged to upgrade to e2fsprogs 1.36 as soon as possible. + +Add support for filesystem with the online resizing via resize inode +feature. Fixed numerous bugs from the Fedora patches. The Fedora +patches also didn't bother to do any consistency checking on the +resize inode, or add any tests to the regression test suite. The "-R +resize=4g" option to mke2fs was a no-op in the Fedora patches, despite +being listed in mke2fs's usage message. All of these shortcomings +have been corrected. + +E2fsck can also also fix filesystems trashed by Fedora's resize2fs +program. In order to do this, the user must run the commands: + + debugfs -w /dev/hdXXX -R "features ^resize_inode" + e2fsck -f /dev/hdXXX + +Optionally, the ext2prepare command can be used to re-enable online +resizing after the filesystem has been fixed. + +The fsck program will now accept an optional filedescriptor argument +to the -C option. (The Fedora version of this patch would sometimes +cause fsck to ignore a parameter on fsck's command line in some rare +cases, sigh.) + +Make sure e2fsprogs doesn't write garbage into the reserved portion of +large inodes. + +Make sure resize2fs releases the blocks belonging to the old inode +table blocks when moving the inode table. (Addresses Debian Bug: +#290894) + +Skip the r_resize_inode test if resize2fs is not compiled (due to +configure --disable-resizer) + +E2fsck now checks the summary filesystem accounting information, and +if any of the information is obviously wrong, it will force a full +filesystem check. (Addresses Debian Bug #291571) + +Fix e2fsck to not complain when the resize_inode feature is enabled, +s_reserved_gdt_blocks is zero, and there is no DIND block allocated in +the resize inode. + +Fix e2fsck to note delete symlinks that contain an extended attribute +after the ext_attr feature flag has been cleared. (Addresses Red Hat +Bugzilla #146284). + +Add new utility program, copy_sparse.c, which is very useful +for dealing with large sparse files (such as e2image files). + +Add support for jnl_blocks[] for debugfs's set_super_value. + +Fix filefrag so that it works correctly with sparse files. + +Filefrag -v will print first and last blocks. + +Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs +and dumpe2fs. + +Add mke2fs support so that it can support filesystems larger than 4TB +automatically, by retrying with a 4k blocksize if the device size is +too big to be expressed using a 1k blocksize. (Addresses Sourceforge +bug #1106631) + +Change blkid to test for NTFS first because Windows sometimes doesn't +clear enough of the parition to confuse the probing routines into +thinking the old filesystem type is still valid. (Addresses Debian +Bug #291990) + +Add support for swap partition label and uuid's in the blkid library. + +Add support to the blkid library to recognize Oracle ASM volumes. + +Make blkid -t display all devices that match the specified criteria, +not just the first one, and work more consistently when the blkid +cache file is not available or set to /dev/null. (Addresses Debian +Bug #290530 and #292425) + +Badblocks will now correctly display block numbers greater than +999,999,999 in its progress display. + +The tune2fs program will not allow the user from setting a ridiculous +number of reserved blocks which would cause e2fsck to assume the +superblock was corrupt. E2fsck's standards for what is a ridiculous +number of reserved block has also been relaxed to 50% of the blocks in +the filesystem. + +The blkid library will return vfat in preference to msdos, and ext3 in +preference to ext2 (if the journalling flag is set) so that mount will +do the right thing. (Addresses Debian bug #287455) + +Mke2fs will now use the -E option for extended options; the old -R +(raid options) option is still accepted for backwards compatibility. +Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707) + +Mke2fs will now accept a size in megabytes, gigabytes, and other units +(via "32m" or "4g" on the command line) if the user finds this more +convenient than specifying a block count. + +Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode +cache conherency problem. + +Debugfs now supports a new command, set_inode_field, which allows a +user to manually set a specific inode field more conveniently, as well +as set entries in the indirect block map. + +Debugfs's set_super_value command has been enhanced so that the user +can set most superblock fields, including the date/time fields and +some of the more newsly added superblock fields. + +E2fsprogs programs now accept an offset to be passed to the file +specifiers, via the syntax: "/tmp/test.img?offset=1024". + +E2fsprogs programs will now accept blocksizes up to 65536; kernel +support on the x86 doesn't exist for now, but it can be useful on +other architectures with page sizes greater than 4k.

(#241183, #248050, +#253595, #247775) + + +Programmer's notes: +------------------- + +Fixed various gcc -Wall warnings. + +The uuid library now has new functions uuid_unparse_upper() and +uuid_unparse_lower() which forces the case of the hex digits to be +upper case, or lower case. + +The build process has been speeded up by enhancing the subst program +to update the modtime on the generated files even when the generated +file hasn't changed. + +The uuid library now uses C99 stdint.h types instead of custom types. + +Updated config.guess and config.sub with newer versions from the FSF. + +Removed out of date .cvsignore files from the source distribution. + +The ext2fs_unlink() function will return an error if both the name and +inode number are unspecified, to avoid doing something surprising +(such as unconditionally deleting the first directory entry). +Directory entries are now deleted by coalescing them with the previous +directory entry if possible, to avoid directory fragmentation. This +is not an issue with the e2fsprogs suite, but may be a problem for +some of the users of libext2fs, such as e2tools. + +Add support for version numbers of the form "1.36-rc1". + +Fix build of mke2fs.static. + +Add basic ext2fs library support for large (EA in inode) inodes. + +The test_io mechanism can now abort after n reads or writes to a +particular block.

The EVMS code uses an ugly union approach since we don't want to +modify the EVMS interfaces. + +Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to +aid build process on systems can use invoke GNU make as "gmake". + +Added regression testing for mke2fs. + +Fixed gcc -Wall nitpicks. + +Fixed various compiler warnings. + +Add portability fixes for FreeBSD and for using fsctl under Darwin to +support ext2 ioctl's. + + +E2fsprogs 1.34 (July 25, 2003) +=============================== + +Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in +a tight loop while waiting for a child fsck to exit in some cases. +This burns CPU times which slows down the low-level filesystem check. + +Added code to mke2fs to assure that the default block size for a +filesystem is at least as big as the sector size of the device, if it +can be determined. + +Changed mke2fs and resize2fs to round the default size of a filesystem +to be an even multiple of the VM pagesize in order to avoid a Linux +kernel bug introduced when the storage of the buffer cache was moved +into the page cache. + +Mke2fs will warn the user when creating a filesystem with journaling +and a blocksize greater than 4096. (Addresses Debian bug #193773) + +Fixed a bug in resize2fs which caused it to fail on filesystems with a +non-empty bad block list. Resize2fs now discards any blocks on the +badblock list which are no longer part of the filesystem as the result +of a filesystem shrink. (Note: this means that shrinking and then +enlarging a filesystem is no longer a reversible operation; +information about bad blocks in the part of the filesystem which is to +be chopped off will be lost.) + +Changed resize2fs so the user can use prefixes to specify the units of +the new filesystem size (sectors, kilobytes, megabytes, or gigabytes), +and to make the error and informational messages explicitly display +the blocksize used by the filesystem, in order to avoid confusion. +(Addresses Debian bug: #189814) + +Added a new debugfs command, dump_unused, which dumps the contents of +all unused blocks to stdout. (Useful as an emergency try-to-find +deleted data command.) + +Added a new debugfs command, imap, which prints the location of a +specified inode in the inode table. + +Fixed a bug in the badblocks program which caused it to use one bit of +randomness in its non-destructive read/write test, instead of using a +full 8 bits of randomness. + +Added a new option (-t) to badblocks, which allows the user to control +the test pattern(s) used when checking a disk. + +The blkid probe function now more correctly detects UDF filesystems. + +Fixed a bug in the blkid library which caused it to not update its +cache if a filesystem changes from having a label to not having a +label. + +Fixed a bug in the blkid library wihch could avoid an infinite loop +in blkid_find_dev_with_tag() if /proc is not mounted and there the +/etc/blkid.tab file has not yet been created. + +Fixed the badblocks program so that the destructive read/write test +honors the -c option, and to use O_DIRECT when possible to avoid +thrashing the system block buffer cache. + +Fixed various NLS issues. + - Added Czech and Swedish translations + - Removed testing NYC translation + - Fixed NLS support for message abbrevations in e2fsck + - Remove de-utf.po, since we shouldn't have two versions using different + charset encodings. + - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to + simplify the statistics reporting in e2fsck. + +Changed configure.in so that its defaults for *BSD systems no longer +build an fsck wrapper, and not to install in /usr/local by default. + +Fixed some minor spelling errors/typo's in e2fsck and the configure +script. + +Fixed various Debian packaging issues (see debian/changelog). + +Updated and clarified man pages.
