Kristof Provost b2e0b24f76 pf: Fix panic on overlapping interface names ... In rare situations[*] it's possible for two different interfaces to have the same name. This confuses pf, because kifs are indexed by name (which is assumed to be unique). As a result we can end up trying to if_rele(NULL), which panics. Explicitly checking the ifp pointer before if_rele() prevents the panic. Note pf will likely behave in unexpected ways on the the overlapping interfaces. [*] Insert an interface in a vnet jail. Rename it to an interface which exists on the host. Remove the jail. There are now two interfaces with the same name in the host.		2018-12-01 09:58:21 +00:00
