Dumpe2fs displays these fields, +tune2fs and mke2fs allows you to set them. E2fsck will automatically +generate a UUID for those volumes that don't have them. + +Put in support for e2fsck to recognize HURD specific ext2 features --- +most notably, the translator block. The e2fsprogs tools will now use +the creator_os field in the superblock to correctly handle different +OS-specific variants of the ext2 filesystem. + +E2fsck now fixes inodes which have a the deletion time set, but which +have a non-zero i_link_count field by offering to clear the deletion +time. Previously e2fsck assumed that the inode was deleted (per 0.3c +ext2 kernel behavior) and offered to unlink the file. + +If e2fsck sets the clean bit, but nothing else, set the exit code +FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it +set the filesystem valid bit when it was previously cleared. :-) This +was needed to make the HURD fsck driver happy. + +If the user refuses to attach an unattached inode, e2fsck will no +longer set the inode's link count. Otherwise, the inode would end up +getting marked as unused, which might cause loss of data later. + +Make the message issued by e2fsck when the superblock is corrupt less +confusing for users. It now mentions that another reason for the +"corrupt superblock" message might be that the partition might not be +an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) + +Make the libext2 library more robust so that e2fsck won't coredump on +an illegal superblock where the blocksize is zero. (f_crashdisk is +the test case). + +By default, create filesystems where the default checkinterval is 6 +months (180 days). Linux servers can be robust enough that 20 reboots +can be a long, long time. + +Added configure flag --enable-old-bitops, which forces the bitops to +use the old (native) bitmask operations. By default on the sparc +platform, the standard ext2 bit ordering is now used. + +Added a new feature to e2fsck to byte-swap filesystems; this can be +used to convert old m68k filesystems to use the standard byte-order +storage for the superblock, inodes, and directory blocks. This +function is invoked by using the '-s' option to e2fsck. + +Debugfs's "dump" command has been enhanced so that it writes out the +exact size of the file so that the nulls at the end of the file are +eliminated. The command also accept a new "-p" option which will +attempt to preserve the ownership, permissions, and file +modification/access times. + +Debugfs has two new options, -f and -R. The -R option allows the user +to execute a single debugfs command from the command line. The -f +option allows the user to specify a "command file" containing debugfs +commands which will get executed. + +Dumpe2fs now pretty prints the check interval, instead of just +printing the check interval as a number of seconds. + +Fix bugs in debugfs: the params command when no filesystem is opened +no longer causes a core dump. It is now possible to unlink a file +when a pathname containing a '/' is specified. + +Tune2fs has a new -C option which sets the number of times the +filesystem has been mounted. + +Fix the chattr '-v' option so that it actually works. Chattr was +being buggy about the -v option parsing. + +Programmers' notes: +------------------- + +The directory lib/uuid contains a set of library routines to generate +DCE compatible UUIDs. + +Extended ext2fs_namei() to handle symbolic links. Added new function +ext2fs_nami_follow() which will follow last symbolic link in the case +where the pathname points to a sym link. + +The ext2fs_block_iterate function will now return the HURD translator +block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the +iterator to return data blocks only. The ext2fs.h file now defines +constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and +BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block +count field of the iterator callback function. + +The test script driver now takes an optional second argument, which is +the test case to be run. This allows you to run a test case without +needing to run the entire test suite. + +On Linux ELF systems, install the .so files in the correct places +(/usr/lib). The .so files must be stored in the same directory as the +.a files. + +Fixed miscellaneous HURD compilation issues with header file being +included in the right order. + +Fixed debugfs so that it resets optind to zero, not one, since setting +optind to zero is more correct. + -- cgit v1.2.3
