Enhance validation to support for reject from inet ingress chains. Note that, reject from inet ingress and netdev ingress differ. Reject packets from inet ingress are sent through ip_local_out() since inet reject emulates the IP layer receive path. So the reject packet follows to classic IP output and postrouting paths. The reject action from netdev ingress assumes the packet not yet entered the IP layer, so the reject packet is sent through dev_queue_xmit(). Therefore, reject packets from netdev ingress do not follow the classic IP output and postrouting paths. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
