Hi, Could you enlighten me if I am wrong: tcp_opt->ucopy is used to optimize receiving of data for currently running process that is issuing tcp_recvmsg so that using of callback mechanism sk->sk_data_ready(sk, skb_len) is not necessary, right? tcp_recvmsg stores current task user_recv = current tp->ucopy.task = user_recv so that if new data arrives (tcp_rcv_established) while tcp_recvmsg is been executed it can be copied on-the-fly, right?
