Subject: [ 03/19] reiserfs: Fix warning and inode leak when deleting inode with xattrs
Date: Wed, 10 Apr 2013 15:50:26 -0700 [thread overview]
Message-ID: <20130410225027.171506481@linuxfoundation.org> (raw)
In-Reply-To: <20130410225026.833809117@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jan Kara <jack@suse.cz>
commit 35e5cbc0af240778e61113286c019837e06aeec6 upstream.
After commit 21d8a15a (lookup_one_len: don't accept . and ..) reiserfs
started failing to delete xattrs from inode. This was due to a buggy
test for '.' and '..' in fill_with_dentries() which resulted in passing
'.' and '..' entries to lookup_one_len() in some cases. That returned
error and so we failed to iterate over all xattrs of and inode.
Fix the test in fill_with_dentries() along the lines of the one in
lookup_one_len().
