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. Otherwise
the regression test suite will fail...
Add additional checks to HTREE directories. We now check the count
and limit fields in the htree header, as well as assuring that the
hash table in each interior node is in ascending order. We also
check to make sure all leaf nodes are have the expected depth in
the tree.
Updated test cases to deal with all of the above.
to determine whether or not a directory entry is a
completely empty leaf block or leaf node. Otherwise
e2fsck might get confused into thinking that a valid dxdir
was corrupted.
caret ('^') character to negate feature sets when using
the -O option. Define the has_journal feature to avoid
confusion about what ^has_journal means.
directories.
Speed up e2fsck slightly by only updating the master superblock;
there is no point to update the backup superblocks.
Fix a small bug in the rehashing code which could leave the indexed
flag set even after the directory was compressed instead of indexed.
(Not fatal, since the kernel will deal with this, but technically
it filesystem isn't consistent, and the filesystem will be marked
as being in error when the kernel comes across the directory. It
should also never happen in real life, since directories that small
will never be indexed, but better safe than sorry.)
Also change the threshold of when directories are indexed, so that
directories of size 2 blocks will be indexed. Otherwise they will
never be indexed by the kernel when they grow.
-R option which skips the root filesystem will skip all of
them. (Addresses Debian bug #159423). Note! This is not
a precedent for dealing intelligently with any other kind
of doubled entry in /etc/fstab!
tune2fs.c (update_feature_set): Allow directory indexing flag to
be set. If so, set the default hash to be TEA, and
initialize the hash seed to a random value.
using a non-zero hash version (i.e., half MD4 or TEA hash).
The hash version wasn't getting copied into dx_dir->hashversion and
this caused the kernel to treat all directories if they were using the
legacy hash, which was Bad.
superblock. Dumpe2fs can now print out these fields, and they
can be modified using debugfs's set_super_value command. Also added
to debugfs was the ability to set s_uuid and s_journal_uuid features
as well.
Fixed up confusion caused by bad parameter names for
get_fs_limits(). Added missing conversion of
volume->vol_size from sectors to bytes. Fix up error
returns for unsupported tasks as EINVAL, not ENOSYS.
Use logical names for the API version numbers, since
the ABI is much more dependent on the headers. Add
code to byte-swap the superblock if necessary.
Revert the shlibs hack.
Makefile.in: Remove inode_io.o from the standard object files
in libext2fs, and only build it if debugfs is enabled
(it requires fileio.o, which is only built if
--disable-debugfs isn't specified to configure).

MD4 ext3 code was only in the CVS tree, and hasn't generally escaped.
Add support for the TEA hash.
