Xin Long cda91d5b91 sctp: cancel a blocking accept when shutdown a listen socket ... As David Laight noticed, "In a multithreaded program it is reasonable to have a thread blocked in accept(). With TCP a subsequent shutdown(listen_fd, SHUT_RDWR) causes the accept to fail. But nothing happens for SCTP." sctp_disconnect() is eventually called when shutdown a listen socket, but nothing is done in this function. This patch sets RCV_SHUTDOWN flag in sk->sk_shutdown there, and adds the check (sk->sk_shutdown & RCV_SHUTDOWN) to break and return in sctp_accept(). Note that shutdown() is only supported on TCP-style SCTP socket. Reported-by: David Laight <David.Laight@aculab.com> Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.
