  "message": "tcp: bug fix Fast Open client retransmission\n\nIf SYN-ACK partially acks SYN-data, the client retransmits the\nremaining data by tcp_retransmit_skb(). This increments lost recovery\nstate variables like tp-\u003eretrans_out in Open state. If loss recovery\nhappens before the retransmission is acked, it triggers the WARN_ON\ncheck in tcp_fastretrans_alert(). For example: the client sends\nSYN-data, gets SYN-ACK acking only ISN, retransmits data, sends\nanother 4 data packets and get 3 dupacks.\n\nSince the retransmission is not caused by network drop it should not\nupdate the recovery state variables. Further the server may return a\nsmaller MSS than the cached MSS used for SYN-data, so the retranmission\nneeds a loop. Otherwise some data will not be retransmitted until timeout\nor other loss recovery events.\n\nSigned-off-by: Yuchung Cheng \u003cycheng@google.com\u003e\nAcked-by: Neal Cardwell \u003cncardwell@google.com\u003e\nSigned-off-by: David S.
