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
