From 971427f353f3c42c8dcef62e7124440df68eb809 Mon Sep 17 00:00:00 2001 From: Andy Zhou Date: Mon, 15 Sep 2014 19:37:25 -0700 Subject: openvswitch: Add recirc and hash action. Recirc action allows a packet to reenter openvswitch processing. currently openvswitch lookup flow for packet received and execute set of actions on that packet, with help of recirc action we can process/modify the packet and recirculate it back in openvswitch for another pass. OVS hash action calculates 5-tupple hash and set hash in flow-key hash. This can be used along with recirculation for distributing packets among different ports for bond devices. For example: OVS bonding can use following actions: Match on: bond flow; Action: hash, recirc(id) Match on: recirc-id == id and hash lower bits == a; Action: output port_bond_a Signed-off-by: Andy Zhou Acked-by: Jesse Gross Signed-off-by: Pravin B Shelar --- net/openvswitch/flow.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'net/openvswitch/flow.c') diff --git a/net/openvswitch/flow.c b/net/openvswitch/flow.c index bf8442071d75..4010423f2831 100644 --- a/net/openvswitch/flow.c +++ b/net/openvswitch/flow.c @@ -1,5 +1,5 @@ /* - * Copyright (c) 2007-2013 Nicira, Inc. + * Copyright (c) 2007-2014 Nicira, Inc. * * This program is free software; you can redistribute it and/or * modify it under the terms of version 2 of the GNU General Public @@ -606,6 +606,11 @@ static int key_extract(struct sk_buff *skb, struct sw_flow_key *key) return 0; } +int ovs_flow_key_update(struct sk_buff *skb, struct sw_flow_key *key) +{ + return key_extract(skb, key); +} + int ovs_flow_key_extract(struct ovs_key_ipv4_tunnel *tun_key, struct sk_buff *skb, struct sw_flow_key *key) { -- cgit v1.2.3
