Subject: [PATCH net-next 00/10] tcp: drop reason additions
Date: Fri, 15 Apr 2022 17:10:38 -0700 [thread overview]
Message-ID: <20220416001048.2218911-1-eric.dumazet@gmail.com> (raw)
From: Eric Dumazet <edumazet@google.com>
Currently, TCP is either missing drop reasons,
or pretending that some useful packets are dropped.
This patch series makes "perf record -a -e skb:kfree_skb"
much more usable.
Eric Dumazet (10):
tcp: consume incoming skb leading to a reset
tcp: get rid of rst_seq_match
tcp: add drop reason support to tcp_validate_incoming()
tcp: make tcp_rcv_state_process() drop monitor friendly
tcp: add drop reasons to tcp_rcv_state_process()
tcp: add two drop reasons for tcp_ack()
tcp: add drop reason support to tcp_prune_ofo_queue()
tcp: make tcp_rcv_synsent_state_process() drop monitor friend
tcp: add drop reasons to tcp_rcv_synsent_state_process()
tcp: add drop reason support to tcp_ofo_queue()
