Can you give me a pointer where to look?

Will this mean that skb->sk may be invalid or that it will point to a a 
context based on the network label the packet has?
In the later case, being able to match remote labels in my match would 
just give added benefit. (Though a netlabel (CIPSO) match would probably 
be more sane than a smack specific match.)
One would just have more choices where to put a rule like this. Like in 
the FORWARD chain.
If non local packets are of no interest, one could put the rule in the 
right chain.

But i think i just misunderstood you here. Since having a socket for non 
local packets is probably not what you meant.
