openvswitch: Introduce ovs_tunnel_route_lookup

2015-01-14T21:32:06+00:00

Introduce ovs_tunnel_route_lookup to consolidate route lookup shared by vxlan, gre, and geneve ports. Signed-off-by: Fan Du Signed-off-by: David S. Miller

net: rename vlan_tx_* helpers since "tx" is misleading there

2015-01-13T22:51:08+00:00

The same macros are used for rx as well. So rename it. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

openvswitch: fix odd_ptr_err.cocci warnings

2014-12-24T20:18:09+00:00

net/openvswitch/vport-gre.c:188:5-11: inconsistent IS_ERR and PTR_ERR, PTR_ERR on line 189 PTR_ERR should access the value just tested by IS_ERR Semantic patch information: There can be false positives in the patch case, where it is the call IS_ERR that is wrong.

openvswitch: Fix vport_send double free

2014-12-24T04:57:31+00:00

Today vport-send has complex error handling because it involves freeing skb and updating stats depending on return value from vport send implementation. This can be simplified by delegating responsibility of freeing skb to the vport implementation for all cases. So that vport-send needs just update stats.

vlan: introduce *vlan_hwaccel_push_inside helpers

2014-11-21T19:20:17+00:00

Use them to push skb->vlan_tci into the payload and avoid code duplication. Signed-off-by: Jiri Pirko Acked-by: Pravin B Shelar Signed-off-by: David S. Miller

vlan: rename __vlan_put_tag to vlan_insert_tag_set_proto

2014-11-21T19:20:17+00:00

Name fits better. Plus there's going to be introduced __vlan_insert_tag later on. Signed-off-by: Jiri Pirko Acked-by: Pravin B Shelar Signed-off-by: David S. Miller

openvswitch: Extend packet attribute for egress tunnel info

2014-11-10T02:58:44+00:00

OVS vswitch has extended IPFIX exporter to export tunnel headers to improve network visibility. To export this information userspace needs to know egress tunnel for given packet. By extending packet attributes datapath can export egress tunnel info for given packet. So that userspace can ask for egress tunnel info in userspace action. This information is used to build IPFIX data for given flow. Signed-off-by: Wenyu Zhang Acked-by: Romain Lenglet Acked-by: Ben Pfaff Signed-off-by: Pravin B Shelar

ovs: Turn vports with dependencies into separate modules

2014-10-28T18:43:18+00:00

The internal and netdev vport remain part of openvswitch.ko. Encap vports including vxlan, gre, and geneve can be built as separate modules and are loaded on demand. Modules can be unloaded after use. Datapath ports keep a reference to the vport module during their lifetime. Allows to remove the error prone maintenance of the global list vport_ops_list.

openvswitch: Add support for Geneve tunneling.

2014-10-06T04:32:21+00:00

The Openvswitch implementation is completely agnostic to the options that are in use and can handle newly defined options without further work. It does this by simply matching on a byte array of options and allowing userspace to setup flows on this array.

openvswitch: Wrap struct ovs_key_ipv4_tunnel in a new structure.

2014-10-06T04:32:20+00:00

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.
