Jerry Chu 168a8f5805 tcp: TCP Fast Open Server - main code path ... This patch adds the main processing path to complete the TFO server patches. A TFO request (i.e., SYN+data packet with a TFO cookie option) first gets processed in tcp_v4_conn_request(). If it passes the various TFO checks by tcp_fastopen_check(), a child socket will be created right away to be accepted by applications, rather than waiting for the 3WHS to finish. In additon to the use of TFO cookie, a simple max_qlen based scheme is put in place to fend off spoofed TFO attack. When a valid ACK comes back to tcp_rcv_state_process(), it will cause the state of the child socket to switch from either TCP_SYN_RECV to TCP_ESTABLISHED, or TCP_FIN_WAIT1 to TCP_FIN_WAIT2. At this time retransmission will resume for any unack'ed (data, FIN,...) segments. Signed-off-by: H.K.
