Hi everybody
I've found what could be a problem in the tcp stack with linux-2.4.17 & 2.4.18. When i run lmbench-2.0-patch2 and that i add the following line of code in tcp_v4_rcv, it<s get added between the if (!ipsec_sk_policy(sk,skb)) ... and if (sk->state == TCP_TIME_WAIT)
if (sk->socket) { if (sk->socket->inode) { printk("Boum\n"); } }
I get a crash, i can give the dump later but for now, I am just wondering if the sk->socket could be invalid when we are receiving a tcp packet. Since from the search i've done it seems to be initialized only when the sock struct is initialized in sock_init_data that get called by inet_create.
But what is more frightening, is that it's alright for sometime and then Boum, crash....
Bye
