Hi..
Because the server is running just now and at the LISTEN state, so there is nothing in the listen queue's request_sock array. So the return value of the Line 8 -- inet_csk_search_req() should be NULL, and then the " return tcp_check_req(sk, skb, req, prev);" at Line 11 should NOT be executed. IS that Right? Could you please explain this function for me? I am very grateful.
Don't know much about it, but my average logic says, even if you're just freshly starting in LISTEN state, that doesn't mean there is no incoming request such as SYN packet, right? And if there is none, that means the code path exits and waits for incoming request. regards, Mulyadi -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
