| E2fsprogs 1.28 (August 31, 2002) |
| ================================ |
| |
| Add support for the Hashed-Tree Directory Indexing to e2fsck. 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. |
