sys/net : Tag: OPENBSD_5_8 if_vlan.c
Log message:
By creating, changing and destroying vlan interfaces multiple times,
root could crash the OpenBSD 5.8 kernel with ifconfig. The reference
counting of ifv_ifih in vlan_config() was wrong, so a use after
free was possible. Reordering the operations fixes it.
Neither 5.7 nor -current is affected.
