2ccb48ebb4 [PATCH] ext3: avoid triggering ext3_error on bad NFS file handle
The inode number out of an NFS file handle gets passed eventually to
ext3_get_inode_block() without any checking.  If ext3_get_inode_block()
allows it to trigger an error, then bad filehandles can have unpleasant
effect - ext3_error() will usually cause a forced read-only remount, or a
panic if `errors=panic' was used.

So remove the call to ext3_error there and put a matching check in
ext3/namei.c where inode numbers are read off storage.

0adb25d2e7 [PATCH] ext3: ext3_symlink should use GFP_NOFS allocations inside
This patch fixes illegal __GFP_FS allocation inside ext3 transaction in
ext3_symlink().  Such allocation may re-enter ext3 code from
try_to_free_pages.  But JBD/ext3 code keeps a pointer to current journal
handle in task_struct and, hence, is not reentrable.

This bug led to "Assertion failure in journal_dirty_metadata()" messages.

Remove redundant NULL check in ext3_lookup() as d_splice_alias() can take NULL

acfa1823d3 [PATCH] Support for dx directories in ext3_get_parent (NFSD)
Henrik Grubbstrom noted:

The 2.6.10 ext3_get_parent attempts to use ext3_find_entry to look up the
entry "..", which fails for dx directories since ".." is not present in the
directory hash table.  The patch below solves this by looking up the dotdot
entry in the dx_root block.

Typical symptoms of the above bug are intermittent claims by nfsd that
files or directories are missing on exported ext3 filesystems.

cf https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=3D150759 and
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=3D144556

ext3_get_parent() is IMHO the wrong place to fix this bug as it introduces
a lot of internals from htree into that function.  Instead, I think this
should be fixed in ext3_find_entry() as in the below patch.  This has the
added advantage that it works for any callers of ext3_find_entry() and not
just ext3_lookup_parent().

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
