I have created jail (using cbsd) with vnet. When I try to added (on jail):
ipfw add 1 allow ip from 'table(10)' to me 

it causes kernel panic

OK, it's not the command that triggers the panic, it's a packet that is then checked against the rule.

I can reproduce it on head.

Fixed in head/ and stable/11. Thanks!
