3.5.7.18 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Aydin Arik <[email protected]> commit c0353c7b5da4cbd2ab8227e84bbc9c79890f24ce upstream. MD5 key lookups on a given TCP socket were being performed incorrectly. This fix alters parameter inputs to the MD5 lookup function tcp_md5_do_lookup, which is called by functions tcp_md5_do_add and tcp_md5_do_del. Specifically, the change now inputs the correct address and address family required to make a proper lookup. Signed-off-by: Aydin Arik <[email protected]> Signed-off-by: David S.
