I tried to hard avoiding a call to rb_first() (via tcp_rtx_queue_head) in tcp_xmit_retransmit_queue(). But this was probably too bold. Quoting Yuchung : We might miss re-arming the RTO if tp->retransmit_skb_hint is not NULL. This can happen when RACK marks the first packet lost again and resets tp->retransmit_skb_hint for example (tcp_rack_mark_skb_lost()) Fixes: 75c119af ("tcp: implement rb-tree based retransmit queue") Signed-off-by:
