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?
Regards,
Juha Heljoranta
