This seems problematic in that it's not a general solution and depends 
always on hooking in at all of the right places in every protocol.  Adding 
a bunch of hooks to protocol-specific code is what got us in trouble with 
the initial LSM submission.

What about using secmark and connection tracking for this, instead?

I'd also suggest moving this discussion to netdev, so other network
developers & maintainers can participate, or just keep track of the
discussion.
