E2fsprogs 1.30 (October 31, 2002)

=================================
|
|
|
|
When resizing a filesystem, and inodes need to moved, resize2fs will
|
|
update the inode's ctime field, and the mtime field of the containing
|
|
directories, so that incremental backups using dump/restore will work
|
|
correctly.
|
|
|
|
In order to avoid spurious errors, e2fsck will check the last
|
|
superblock write time to determine whether or not it can safely use
|
|
the LOW_DTIME checks to determine if there are inodes on the orphan
|
|
inode linked list that had somehow gotten disconnected. (Addresses
|
|
Sourceforge bug #620980)
|
|
|
|
Partition in /proc/partitions that being with the string "lvm" are
|
|
considered real partitions even if they do not end with a number.
|
|
|
|
Fixed a bug in the the uuid generation function, where if /dev/urandom
|
|
is not present, but /dev/random is, and there isn't sufficient
|
|
entropy, the get_random_byte function could spin a loop forever.
|
|
|
|
E2fsck, mke2fs, etc. will now reliably notice when image files are
|
|
mounted using the loopback interface. (Addresses Sourceforge bug
|
|
#619119)
|
|
|
|
When flushing buffers (as is done by badblocks, for example) check to
|
|
see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
|
|
FDFLUSH ioctl which causes the MD device driver which causes confusing
|
|
syslog messages about obsolete ioctl messages. (Addresses Sourceforge
|
|
bug #545832).
|
|
|
|
Debugfs's write command now checks to see if the destination filename
|
|
exists before creating it. (Addresses Sourceforge bug #478195.)
|
|
|
|
When installing man pages, search for compressed man pages using all
|
|
commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
|
|
|
|
Fixed a bug in fsck where multiple filesystems specified on the
|
|
command were not being checked in parallel due to a logic bug
|
|
introduced to support the FSCK_MAX_INST environment variable.
|
|
|
|
We have added a new superblock field, s_mkfs_time, which indicates
|
|
when a filesystem was created. It is set via mke2fs, and printed out
|
|
by dumpe2fs, but is not actually touched by the kernel.
|
|
|
|
Dumpe2fs has been made more robust by not aborting if there is an
|
|
error reading the block/inode bitmaps; instead it will still print out
|
|
the location of the block/inode bitmaps and inode table.
|
|
|
|
Add support for the an alternative block group descriptor layout which
|
|
allows for on-line resizing without needing to prepare the filesystem
|
|
in advance. (This is the incompat feature flag meta_bg.)
|
|
|
|
Add support for storing default mount options in the superblock, so
|
|
that the filesystem can be mounted with specific mount options without
|
|
needing to specify them on the mount command line or in the /etc/fstab
|
|
file.
|
|
|
|
Add support for a new inode flag, which is to be used for indicating
|
|
the top of directory hierarchies for the Orlov block allocator.
|
|
|
|
Fix e2fsck so that if it creates the lost+found directory, it does so
|
|
with the more appropriate permissions of 0700. Also change
|
|
mklost+found so that it also creates the directory 0700.
|
|
|
|
Fixed format bug in e2fsck if NLS is in use.
|
|
|
|
Add a German translation for e2fsprogs's NLS support.
|
|
|
|
Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
|
|
the beginning of the inode table. This won't matter much, since if
|
|
there is a bad block at the beginning of the inode table, the root
|
|
directory won't be available. But at least e2fsck won't crash in this
|
|
case.
|
|
|
|
Fixed endian problems in the htree code for e2fsck and debugfs.
|
|
|
|
When byte-swapping a filesystem on a PPC architecture, byte-swap the
|
|
bitmaps since the historical big-endian ext2 variant had byte-swapped
|
|
bitmaps, and the ext2fs library assumes this. This fixes the
|
|
regression test suite on PPC machines.
|
|
|
|
Fix e2image so that it handles a bad block in the inode table
|
|
appropriately.
|
|
|
|
E2fsck now uses a more sophisticated algorithm to salvage corrupted
|
|
directories that recovers more information in the corrupted directory
|
|
block.
|
|
|
|
E2fsck now performs additional consistency checks on indexed (HTREE)
|
|
directories.
|
|
|
|
Fix a bug where e2fsck might get confused about whether a completely
|
|
empty directory block is an empty leaf block or an interior htree
|
|
node. This could cause e2fsck to get confused into think that a valid
|
|
indexed directory was corrupted.
|
|
|
|
E2fsck no longer creates an empty directory entry at the end of a
|
|
directory block when optimizing a directory. This would cause some
|
|
earlier versions of the dxdir kernel code to corrupt the directory
|
|
when attempting to split a node containing an empty directory entry.
|
|
|
|
E2fsck could sometimes in rare circumstances leave the indexed flag
|
|
set after a small directory was optimized by compressing it instead of
|
|
indexing it. (This should never happen in real life, since
|
|
directories that small wouldn't have been indexed, but better safe
|
|
than sorry.)
|
|
|
|
E2fsck now only updates the master superblock in all cases. This
|
|
slightly shortens its run time.
|
|
|
|
Ext2ed can deal with directory entries of length 0; previously it
|
|
would get stuck in an infinite loop.
|
|
|
|
Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
|
|
specifiers. (Sourceforge patch #613447)
|
|
|
|
Badblocks will now work correctly on read-only devices such as
|
|
CD-ROM's. (Sourceforge patch #600451)
|
|
|
|
Updated and clarified man pages. (Addresses Debian bug #167108)
