One common source for these drops are ACK packets coming too late. A prior packet with payload already changed tp->rcv_nxt. Add TCP_RFC7323_PAWS_ACK new drop reason, and do not generate a DUPACK for such old ACK. ==================== Link: https://patch.msgid.link/20250113135558.3180360-1-edumazet@google.com Signed-off-by: Jakub Kicinski --- 63803c4a6d5f94fccc076b5e53442c747eea8d63
