From 408fbc22ef1efb00dd896acd00e9f7d9b641e047 Mon Sep 17 00:00:00 2001 From: Jamal Hadi Salim Date: Sun, 18 Sep 2016 07:31:43 -0400 Subject: net sched ife action: Introduce skb tcindex metadata encap decap Sample use case of how this is encoded: user space via tuntap (or a connected VM/Machine/container) encodes the tcindex TLV. Sample use case of decoding: IFE action decodes it and the skb->tc_index is then used to classify. So something like this for encoded ICMP packets: .. first decode then reclassify... skb->tcindex will be set sudo $TC filter add dev $ETH parent ffff: prio 2 protocol 0xbeef \ u32 match u32 0 0 flowid 1:1 \ action ife decode reclassify ...next match the decode icmp packet... sudo $TC filter add dev $ETH parent ffff: prio 4 protocol ip \ u32 match ip protocol 1 0xff flowid 1:1 \ action continue ... last classify it using the tcindex classifier and do someaction.. sudo $TC filter add dev $ETH parent ffff: prio 5 protocol ip \ handle 0x11 tcindex classid 1:1 \ action blah..
