Hyunwoo Kim a3967128bc net/x25: Fix to not accept on connected socket ... [ Upstream commit f2b0b5210f ] When listen() and accept() are called on an x25 socket that connect() succeeds, accept() succeeds immediately. This is because x25_connect() queues the skb to sk->sk_receive_queue, and x25_accept() dequeues it. This creates a child socket with the sk of the parent x25 socket, which can cause confusion. Fix x25_listen() to return -EINVAL if the socket has already been successfully connect()ed to avoid this issue. Signed-off-by: Hyunwoo Kim <v4bel@theori.io> Signed-off-by: David S.
