I think what it comes down to is that we can filter in socket
context, but the only useable attributes in both input- and
output-path for owner-matching are
sk->sk_socket->file->f_{uid,gid}. This should still be enough
for many usage cases (and for mine), so I'm going to finish the
patch.
@james: Out of interest, what are the requirements for selinux?

Patrick
