| H A D | tcp_diag.c | b58662a5 Thu Sep 05 15:20:41 CDT 2019 Eric Dumazet <edumazet@google.com> tcp: ulp: fix possible crash in tcp_diag_get_aux_size()
tcp_diag_get_aux_size() can be called with sockets in any state.
icsk_ulp_ops is only present for full sockets.
For SYN_RECV or TIME_WAIT ones we would access garbage.
