Bug #1580

Updated by martin1234 6 months ago

Not quite sure if the problem is in either of the two aforementioned acts or in

the combination, but while doing that (with netif names I'm thinking

of "ifconfig some_netif name new_name") I was able to panic the machine.

After getting "kernel: Non-unique normal route, mask not entered" in the dmesg

(immediatelly after loading my custom pf.conf - do note, that it does not

happen all the time, loaded the rules quite a few times to get this message),

I loaded my pf.conf again (pfctl -f /etc/pf.conf) and the machine fortunately

panicked for me (in the previous two instances of this problem, the machine

hanged and was completely unresponsive ... to ping, serial console, everything

was dead).

The dump is located at leaf:~rumko/crash/pf/ and the backtrace is:
