openvswitch: Return vport module ref before destruction

2015-03-31T19:59:50Z

Return module reference before invoking the respective vport ->destroy() function. This is needed as ovs_vport_del() is not invoked inside an RCU read side critical section so the kfree can occur immediately before returning to ovs_vport_del(). Returning the module reference before ->destroy() is safe because the module unregistration is blocked on ovs_lock which we hold while destroying the datapath.

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

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

openvswitch: Consistently include VLAN header in flow and port stats.

2015-01-02T21:14:20Z

Until now, when VLAN acceleration was in use, the bytes of the VLAN header were not included in port or flow byte counters. They were however included when VLAN acceleration was not used. This commit corrects the inconsistency, by always including the VLAN header in byte counters.

openvswitch: Fix vport_send double free

2014-12-24T04:57:31Z

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.

openvswitch: Extend packet attribute for egress tunnel info

2014-11-10T02:58:44Z

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

openvswitch: Export symbols as GPL symbols.

vport can be compiled as modules, therefore openvswitch needs to export few symbols. Export them as GPL symbols. CC: Thomas Graf Signed-off-by: Pravin B Shelar

ovs: Turn vports with dependencies into separate modules

2014-10-28T18:43:18Z

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.
