state is not applicable. The fix just reverts the new code that blocked
packets where fr_addstate() fails. This is not correct in all cases, but
blocking them is a bit drastic and breaks existing functionality. The proper
fix is to change fr_addstate() to return:
- state added
- adding state failed
- adding state is not applicable
and then filter packets only in the second case. I am leaving this for someone
else.
