Theodore Ts'o 60bf373e45 Break up RELEASE-NOTES into files in doc/RelNotes
The RELEASE-NOTES file was getting too big as be unweildy.  It also
made it hard to have simultaneous releases of older maintenance
releases.  So split it up into smaller files in the doc/RelNotes
directory.

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)
