Subject: [PATCH v3 net-next 0/2] tcp: Make simultaneous connect() RFC-compliant.

Patch 1 fixes an issue that BPF TCP option parser is triggered for ACK
instead of SYN+ACK in the case of simultaneous connect().

Patch 2 removes an wrong assumption in tcp_ao/self-connnect tests.

v3:
  * Use (sk->sk_state == TCP_SYN_RECV && sk->sk_socket) to detect cross SYN case

v2: https://lore.kernel.org/netdev/20240708180852.92919-1-kuniyu@amazon.com/
  * Target net-next and remove Fixes: tag
  * Don't skip bpf_skops_parse_hdr() to centralise sk_state check
  * Remove unnecessary ACK after SYN+ACK
  * Add patch 2

v1: https://lore.kernel.org/netdev/20240704035703.95065-1-kuniyu@amazon.com/


Kuniyuki Iwashima (2):
  tcp: Don't drop SYN+ACK for simultaneous connect().
  selftests: tcp: Remove broken SNMP assumptions for TCP AO self-connect
    tests.
