openvswitch: Wrap struct ovs_key_ipv4_tunnel in a new structure.

2014-10-06T04:32:20Z

Currently, the flow information that is matched for tunnels and the tunnel data passed around with packets is the same. However, as additional information is added this is not necessarily desirable, as in the case of pointers. This adds a new structure for tunnel metadata which currently contains only the existing struct. This change is purely internal to the kernel since the current OVS_KEY_ATTR_IPV4_TUNNEL is simply a compressed version of OVS_KEY_ATTR_TUNNEL that is translated at flow setup.

openvswitch: Add recirc and hash action.

2014-09-16T06:28:14Z

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

openvswitch: Use tun_key only for egress tunnel path.

2014-09-16T06:28:13Z

Currently tun_key is used for passing tunnel information on ingress and egress path, this cause confusion. Following patch removes its use on ingress path make it egress only parameter. Signed-off-by: Pravin B Shelar Acked-by: Andy Zhou

openvswitch: refactor ovs flow extract API.

2014-09-16T06:28:13Z

OVS flow extract is called on packet receive or packet execute code path. Following patch defines separate API for extracting flow-key in packet execute code path. Signed-off-by: Pravin B Shelar Acked-by: Andy Zhou

openvswitch: Remove pkt_key from OVS_CB

2014-09-16T06:28:13Z

OVS keeps pointer to packet key in skb->cb, but the packet key is store on stack. This could make code bit tricky. So it is better to get rid of the pointer. Signed-off-by: Pravin B Shelar

net: Remove unlikely() for WARN_ON() conditions

2014-07-31T00:41:47Z

No need for the unlikely(), WARN_ON() and BUG_ON() internally use unlikely() on the condition. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller

openvswitch: Use net_ratelimit in OVS_NLERR

2014-05-16T20:40:28Z

Each use of pr__once has a per-site flag. Some of the OVS_NLERR messages look as if seeing them multiple times could be useful, so use net_ratelimit() instead of pr_info_once. Signed-off-by: Joe Perches Signed-off-by: Jesse Gross

openvswitch: rename ->sync to ->syncp

2014-02-15T07:06:23Z

Openvswitch defines u64_stats_sync as ->sync rather than ->syncp, so fails to compile with netdev_alloc_pcpu_stats(). So just rename it to ->syncp.
