ext4: fix memory leak in xattr
commit 6e4ea8e33b2057b85d75175dd89b93f5e26de3bc upstream. If we take the 2nd retry path in ext4_expand_extra_isize_ea, we potentionally return from the function without having freed these allocations. If we don't do the return, we over-write the previous allocation pointers, so we leak either way. Spotted with Coverity. [ Fixed by tytso to set is and bs to NULL after freeing these pointers, in case in the retry loop we later end up triggering an error causing a jump to cleanup, at which point we could have a double free bug. -- Ted ] Signed-off-by: Dave Jones <davej@fedoraproject.org> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Reviewed-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
