The bridge netfilter code attaches a fake dst_entry with a pointer to a fake net_device structure to skbs it passes up to IPv4 netfilter. This leads to crashes when the skb is passed to __ip_route_output_key when dereferencing the namespace pointer. Since bridging can currently only operate in the init_net namespace, the easiest fix for now is to initialize the nd_net pointer of the fake net_device struct to &init_net.
