Those are the places that are bugs. Setting skb->sk=NULL is a bad thing to be doing
in 2.1.x (it made sense in 2.0). Probably we need skb_disown(skb) to be sure
behaviour is always right

Right now it may seem to, but the logical extension to the socket filters is
to be able to bounce buffers through secondary queues to user space
daemons on rule matches (like Digitals firewall) at that point we need to
account first.
