Zhongqiu Duan 3479c7549f tcp/dccp: allow a connection when sk_max_ack_backlog is zero ... If the backlog of listen() is set to zero, sk_acceptq_is_full() allows one connection to be made, but inet_csk_reqsk_queue_is_full() does not. When the net.ipv4.tcp_syncookies is zero, inet_csk_reqsk_queue_is_full() will cause an immediate drop before the sk_acceptq_is_full() check in tcp_conn_request(), resulting in no connection can be made. This patch tries to keep consistent with 64a146513f ("[NET]: Revert incorrect accept queue backlog changes.").
