i'm far from being a networking expert, so i might be plain
wrong. after having a look at the kernel sources i think it works in
the following way:
struct inet_sock *inet = inet_sk(socket->sk);
the data you are looking for are:
inet->saddr
inet->sport
inet->daddr
inet->dport
btw: for these kind of questions it is better to write to the
kernelnewbies list (kernelnewbies@nl.linux.org)
best regards
