      tcp: TCP Fast Open Server - record retransmits after 3WHS · 30099b2e
      Neal Cardwell authored
      
      
      When recording the number of SYNACK retransmits for servers using TCP
      Fast Open, fix the code to ensure that we copy over the retransmit
      count from the request_sock after we receive the ACK that completes
      the 3-way handshake.
      
      The story here is similar to that of SYNACK RTT
      measurements. Previously we were always doing this in
      tcp_v4_syn_recv_sock(). However, for TCP Fast Open connections
      tcp_v4_conn_req_fastopen() calls tcp_v4_syn_recv_sock() at the time we
      receive the SYN. So for TFO we must copy the final SYNACK retransmit
      count in tcp_rcv_state_process().
      
      Note that copying over the SYNACK retransmit count will give us the
      correct count since, as is mentioned in a comment in
      tcp_retransmit_timer(), before we receive an ACK for our SYN-ACK a TFO
      passive connection does not retransmit anything else (e.g., data or
      FIN segments).
