The current code does not check sk->sk_shutdown & RCV_SHUTDOWN. tls_sw_recvmsg may return a positive value in the case where bytes have already been copied when the socket is shutdown. sk->sk_err has been cleared, causing the tls_wait_data to hang forever on a subsequent invocation. Checking sk->sk_shutdown & RCV_SHUTDOWN, as in tcp_recvmsg, fixes this problem.
