Actually, for what I'm trying to do, switching to userspace is probably
not that dangerous.  The reason is because I am trying to match one
packet, then the rule for the matching is actually switched off.  In
other words, I want to match a single packet, run some user code, then
remove the rule for matching that packet.  Given this, I can't see how
the scenario you've laid out would be that big of a threat.
