parent[TCP]: Fix oops caused by __tcp_put_md5sig_pool() (diff)
[SCTP]: Handle address add/delete events in a more efficient way.
Currently in SCTP, we maintain a local address list by rebuilding the whole list from the device list whenever we get a address add/delete event. This patch fixes it by only adding/deleting the address for which we receive the event. Also removed the sctp_local_addr_lock() which is no longer needed as we now use list_for_each_safe() to traverse this list. This fixes the bugs in sctp_copy_laddrs_xxx() routines where we do copy_to_user() while holding this lock. Signed-off-by: Sridhar Samudrala <sri@us.ibm.com> Signed-off-by: David S.
