How to acquire local TCP socks?

haoyu · 09-07-2007, 09:41 PM

I'm writing a kernel module about network, in which I need to traverse all ``ESTABLISHED'' TCP connections, and get ``struct sock'' of those matching specific (local IPv6, peer IPv6).

Please tell me which kernel data structures and/or functions should I refer to?

Look into net/socket.c That's the place where nearly all basic socket operations are defined. Also, the function __inet_lookup_established (include/net/inet_hashtables.h) may be useful for you.

Thank you very much.
Infact, I've already examined the code of ``__inet_lookup_established'' and found that many of its operations and data structures are port essential ones.
Anyway, I'll check the codes in ``net/socket.c''.
