Support +for setting the htree flag is not included yet, although it can be +manually turned on via the debugfs program. + +Clarified e2fsck error message which is printed when it cannot find +sufficient contiguous block when relocating filesystem metadata. + +Added support for building an EVMS plugin module for ext2/3. This +module is substantially the same as the EVMS module shipping with EVMS +1.1, with one or two bugfixes. E2fsprogs can also build this plugin +for use with EVMS 1.0 (which did not include the ext2 plugin module), +if the configure --enable-old-evms flag is given. + +Fsck will search through EVMS volumes when trying to resolve +filesystem specifications such as LABEL=xxx or UUID=xxx. + +Added a new utility program, /sbin/findfs, which will return +filesystem specifications such as LABEL=xxx or UUID=xxx, and prints +the device name. + +Update and clarified various man pages. (addresses Debian Bug #145044, +#146437, #131350, #151990, #144621, #141938) + +If there are no filesystems specified on fsck's command line, fsck now +treat that as if the -As options were given. Previously it would +simply do nothing. (Addresses Debian Bug #153102) + +Mke2fs no longer treats a failure to be able to clear the MD signature +at the end of the filesystem as a fatal error. (Addresses Debian Bug +#155007) + +The e2p library functions (which are used by lsattr and chattr) now +double check to make sure the file is a regular file or directory +before attempting to use the ext2 ioctls. Some device drivers +unfortunately respond to the ext2 ioctl's with unknown behaviour. +(Addresses Debian Bug #152029). + +The extended attribute handling has been updated to correspond with +the latest V2 bestbits ACL code. + +Fixed bug in e2fsck which caused it to not clear the dtime field when +processing truncated inodes on the orphan list. This could cause data +loss(!) if a filesystem is rebooted before a truncate has been +committed. + +E2fsck now uses red/black trees in pass1b, which removes some O(n**2) +algorithms. This makes e2fsck much faster in the case of severely +corrupted filesystems where a large number of blocks are claimed by a +large number of inodes. (Thanks to the 2.5 IDE device driver for +inspiring this work.) + +Resize2fs has been significantly sped up when shrinking and expanding +a filesystem by a very small number of blocks (for example, when EVMS +is converting a partition to be an EVMS legacy volume). + +Added a new option to e2fsck, -D, which will optimize or compress all +of the directories in the filesystem. + +E2fsck now catches SIGINT and SIGTERM to make sure it will can +properly clean up and only exit at safe points. Fsck will pass +SIGINT/SIGTERM to its child processes, and wait until they have all +exited before it exits. + +The uuid parsing code in the uuid library now properly complains when +an illegally formatted uuid is presented to it. (Addresses Debian bug +#152891) + +Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10 +and 2.4.17, since the workaround can cause problems when using a 2.4 +kernel with an old version of glibc built with the 2.2 headers. + +Fixed a bug in mke2fs where it wasn't properly clearing the initial +superblock used by other filesystems. (Addresses Debian bug #147256.) + +Added support for the synchronous directory feature written by Andrew +Morton. + +The debugfs program can delete directories using the rmdir command. + +Add support for 8k and 16k filesystems (for systems with page sizes +that are greater or equal to 8k or 16k, respectively). Note that +these filesystems can not be mounted on x86 systems, or other systems +with only 4k page sizes, due to limitations in the current Linux VM +code. + +Resize2fs requires that the filesystem state be valid and have no +errors; otherwise, e2fsck -f must be run first. (Previously it simply +required that the last fsck time be greater than the last mount time.) + +Configure now defaults the man pages directory to /usr/share/man on +Linux systems. + +E2fsck now offers to truncate inodes which contain too many blocks (so +that i_blocks would overflow. Also fixed handling of large sparse +files. + +E2fsck now more completely checks for symlink validity, including +requiring NULL termination and length checks. + +E2fsck will offer to try forcing a disk write to remap a bad block +after finding a read error when reading a filesystem metadata block. + +Fixed a bug in debugfs which caused the -b and -s options to crash +debugfs, as well as breaking the testb, setb, and clearb functions. + +Added a bmap command to debugfs which calculates the logical to +physical block mapping for a particular inode. + +Fixed a bug in code which checked to see if a device was mounted which +sometimes (rarely) failed in the case of a plain file. + +Fixed a bug in resize2fs where when it reported an error, it would +print a message erroneously indicating that the filesystem had been +resized before it aborted. + +When resizing a plain file which is smaller than the requested size, +resize2fs will attempt to extended the file so that programs like +e2fsck will not complain that the file is too small. + +Resize2fs will print the actual new size of the filesystem when it is +finished resizing. + +Fixed a bug in debugfs where "ls -l" would report incorrect file type +information on big-endian systems. + + +Programmer's notes: +------------------- + +Fixed collisions with C++ reserved words. + +Added portability fixes for building e2fsprogs on the HURD and AIX. + +Added the ext2ed program for creation of test cases. (ext2ed has many +limitations and bugs which make it unsuitable for production use.) + +The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new +flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the +name_len field is byte swapped on big-endian machines, since in the +V2 structure, name_len is a char field which is doesn't need to be +byte swapped --- except if an old-style kernel had byte-swapped the +name_len field as part of the V1 structure. + -- cgit v1.2.3
