Hi, On today's checkout of RELENG_7 it is possible to crash the system using the following commands: ifconfig vlan0 create ifconfig vlan0 -vlandev Crash is located in if_vlan.c in vlan_unconfig_locked() when dereferencing a NULL pointer (ifv->ifv_trunk) to access parent interface using PARENT macro.
