From bc3103f1ed405de587fa43d8b0671e615505a700 Mon Sep 17 00:00:00 2001 From: Amir Vadai Date: Thu, 8 Sep 2016 16:23:47 +0300 Subject: net/sched: cls_flower: Classify packet in ip tunnels Introduce classifying by metadata extracted by the tunnel device. Outer header fields - source/dest ip and tunnel id, are extracted from the metadata when classifying. For example, the following will add a filter on the ingress Qdisc of shared vxlan device named 'vxlan0'. To forward packets with outer src ip 11.11.0.2, dst ip 11.11.0.1 and tunnel id 11. The packets will be forwarded to tap device 'vnet0' (after metadata is released): $ tc filter add dev vxlan0 protocol ip parent ffff: \ flower \ enc_src_ip 11.11.0.2 \ enc_dst_ip 11.11.0.1 \ enc_key_id 11 \ dst_ip 11.11.11.1 \ action tunnel_key release \ action mirred egress redirect dev vnet0 The action tunnel_key, will be introduced in the next patch in this series.
