Vlad Yasevich ae53b5bd77 sctp: Fix another socket race during accept/peeloff ... There is a race between sctp_rcv() and sctp_accept() where we have moved the association from the listening socket to the accepted socket, but sctp_rcv() processing cached the old socket and continues to use it. The easy solution is to check for the socket mismatch once we've grabed the socket lock. If we hit a mis-match, that means that were are currently holding the lock on the listening socket, but the association is refrencing a newly accepted socket. We need to drop the lock on the old socket and grab the lock on the new one. A more proper solution might be to create accepted sockets when the new association is established, similar to TCP. That would eliminate the race for 1-to-1 style sockets, but it would still existing for 1-to-many sockets where a user wished to peeloff an association. For now, we'll live with this easy solution as it addresses the problem.
