I did some dummy tests on "fixed" current (simple dummynet configuration + traffic + ipfw reloaded every second) and did not have any issues. At present I don't have old -current without fix to reproduce the crash, but on 7-STABLE running this test I saw in dmesg many ipfw: ouch!, skip past end of rules, denying packet messages and one time crashed the system. So it looks like my testbase rather good and would have found problems with fixed current if they still had had. -- Mikolaj Golub
