This is the default behaviour if e2fsck is +using a backup superblock, since the needs_recovery flag will never be +set in the backup superblock copies. + +E2fsck now automatically finds the backup superblock/group descriptors +even when the primary superblock is completely destroyed for 2k and 4k +filesystems. (Previously it just guessed/assumed that we were dealing +with a 1k filesystem in that case, and users had to manually specify +the backup superblock number.) + +Fixed a bug in e2fsck where it dereferences a null pointer when there +is a problem opening a filesystem in preen mode. + +E2fsck now handles external journals correctly; previously it trashed +the external journal device if the journal needed to be replayed. + +Work around ulimit incompatibility problem caused by recent 2.4 +kernels; the unix IO module will automatically try to set any resource +limits to be infinite on startup. + +Fixed a bug in e2fsck where it wasn't allocating a new block or inode +bitmap if it wasn't present and the blocksize was 2k or 4k. + (Addresses Debian Bug #116975) + +E2fsck will check and fix botched ext3 V1 to V2 superblock updates by +clearing the new V2 fields if they do not make sense or if the ext3 +superblock is version 1 superblock. + +E2fsck will automatically relocate the ext3 journal from a visible +file (i.e., /.journal) to an hidden inode if the filesystem has been +opened read/write. This allows the users to add a journal while the +filesystem is mounted, but the next time the system is rebooted, the +journal file will disappear. This avoids problems with backups, +stupid operators with superuser bits, etc. + +Fix a bug in fsck where it would not support a filesystem type of +"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx. + +Fsck now supports fstab entries of the form "ext3,ext2". It will also +automatically identify reiserfs filesystems. + +The number of processes spawned by fsck can now be limited using the +FSCK_MAX_INST environment variable. + +Fsck now searches the LVM proc hierarchy to find logical volumes which +should be searched for UUID and label information. + +Work around a bug in 2.4.10+ kernels by trying to unset the filesize +limit if at all possible, when opening a block device. (The filesize +limit shouldn't be applied against writes to a block device.) + +In mke2fs and e2fsck, specifying the -c option twice will now do +a read/write test on the disk. Update the man pages to encourage +using the -c option, and to discouraging running badblocks separately, +since users tend to forget to set the blocksize when running +badblocks. + +Mke2fs now automatically clears the immutable attribute on a +pre-existing .journal file left over from a previous failed attempt to +add a journal to an already-mounted filesystem. + +Fixed mke2fs's exit codes to consistently indicate when the mke2fs +operation failed. + +Mke2fs now creates the lost+found directory with permissions of 0700, +so that files that had previously lived in protected directory are +safe if they get dropped in lost+found and the system administrator +doesn't deal with immediately. (Addresses Debian #bug 118443) + +Mke2fs and e2fsck (and all programs that use the +ext2fs_check_if_mounted function) will now properly identify that a +device is mounted, even in cases where devfs has confused things with +multiple devices names with the same identity, or if a dim-witted +system administrator has done something stupid like creating device +file aliases in their home directory. Also now checks for swap devices +by using /proc/swaps. (Addresses Debian bug #106622) + +Added a new option (-T) to tune2fs which sets the time a filesystem +was last checked. + +Speed up e2image when creating sparse raw image files by optimizing +away excess lseek() system calls. + +Fix support of large (> 2GB) files when used as a filesystem in +mke2fs, tune2fs, debugfs, and findsuper. + +Debugfs's stat and icheck commands now properly deals with large (> +2GB) files. + +Debugfs's set_super_value command now prints out the list of valid +superblock fields which can be set using the command. + +Debugfs's rm and kill_file command now updates the superblock free block +and inode counts, thus keeping the filesystem consistent. + +Debugfs's lsdel command now takes an optional argument which allows +the user to only see the most recently deleted files. + +A new command (undel) was added to debugfs which automates +undeleting a deleted inode and linking it back to a directory. + +Debugfs's ls command now takes a new option, -d, which lists +deleted directory entries. + +Debugfs's testb, freeb, setb, and find_free_block commands now take an +optional count argument. + +Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will +be used to signal that a particular inode should not be eligible for +tail-merging --- this is needed for programs like LILO. + +The findsuper (an unreleased, uninstalled utility program) has been +improved to add extra validity checks and to add a progress meter. +(It is still an unsupported program; the officially supported way to +recover from a trashed partition table is to use gpart; findsuper is +for wizards only. :-) + +Debugfs was fixed to compile with "configure --disable-swapfs". + +Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) + +Added new translation file for Turkish. + +Programmer's notes: +------------------- + +Fix general gcc -Wall complaints. + +E2fsprogs (mostly) works with the dietlibc. + +The programming texinfo file has been expanded to include description +of additional libext2fs functions. (Still not completely done, but a +lot of the more important functions have been documented.) + +Added a umask structure to struct_ext2_filsys, which currently only +modifies the behaviour of ext2fs_mkdir(), but if we add any file +creation functions to libext2fs, we should also make sure they respect +the umask setting. + +The build-rpm script was fixed to be a bit more safe. + +The tests' Makefile now has a way of automating test case creation +for e2fsck, using "make testnew". + +Created a new function, ext2fs_dir_iterate2 which passes more +information to the callback function (identical to the one used by +ext2fs_dblist_dir_iterate). The directory iterator functions take a +new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted +directory entries. If the directory entry is deleted, the callback +function will be called with the entry parameter set to +DIRENT_DELETED_FILE. + +Added new functions, ext2fs_inode_alloc_stats and +ext2fs_block_alloc_stats, which takes updates block/inode allocation +statistics in the bitmaps, block group descriptors, and superblock +when inodes or blocks are allocated or deallocated. + |
