Hi All,
Iptables can filter output traffic by uid, for example iptables -A
OUTPUT -m owner --uid-owner 100 -p udp -j DROP.
I need to implement the same for input traffic. Anyone have any idea
of how can i do it (where i must start)? I am new to netfilter
development i tried some simple modifications on code with no success.
I would really appreciate any kind of help.
Regards,
Glauco.

I've added socket layer hooks a couple of years ago for that
purpose, but we've never merged it. James Morris based some
work on them, I think this should be the latest version:

Thanks Patrick!
I gave a quick look in the patches and I think they will help me a lot.
