genetlink: pass family to functions using groups

2013-11-19T21:39:06Z

This doesn't really change anything, but prepares for the next patch that will change the APIs to pass the group ID within the family, rather than the global group ID. Signed-off-by: Johannes Berg Signed-off-by: David S. Miller

openvswitch: collect mega flow mask stats

2013-10-22T17:42:46Z

Collect mega flow mask stats. ovs-dpctl show command can be used to display them for debugging and performance tuning. Signed-off-by: Andy Zhou Signed-off-by: Jesse Gross

openvswitch: Move mega-flow list out of rehashing struct.

2013-10-04T07:18:26Z

ovs-flow rehash does not touch mega flow list. Following patch moves it dp struct datapath. Avoid one extra indirection for accessing mega-flow list head on every packet receive. Signed-off-by: Pravin B Shelar Signed-off-by: Jesse Gross

openvswitch: Restructure datapath.c and flow.c

2013-10-04T01:16:47Z

Over the time datapath.c and flow.c has became pretty large files. Following patch restructures functionality of component into three different components: flow.c: contains flow extract. flow_netlink.c: netlink flow api. flow_table.c: flow table api. This patch restructures code without changing logic. Signed-off-by: Pravin B Shelar Signed-off-by: Jesse Gross

openvswitch: Move flow table rehashing to flow install.

2013-09-17T16:38:23Z

Rehashing in ovs-workqueue can cause ovs-mutex lock contentions in case of heavy flow setups where both needs ovs-mutex. So by moving rehashing to flow-setup we can eliminate contention. This also simplify ovs locking and reduces dependence on workqueue. Signed-off-by: Pravin B Shelar Signed-off-by: Jesse Gross

openvswitch: Mega flow implementation

2013-08-23T23:43:07Z

Add wildcarded flow support in kernel datapath. Wildcarded flow can improve OVS flow set up performance by avoid sending matching new flows to the user space program. The exact performance boost will largely dependent on wildcarded flow hit rate. In case all new flows hits wildcard flows, the flow set up rate is within 5% of that of linux bridge module. Pravin has made significant contributions to this patch. Including API clean ups and bug fixes. Signed-off-by: Pravin B Shelar Signed-off-by: Andy Zhou Signed-off-by: Jesse Gross

openvswitch: Add gre tunnel support.

2013-06-20T01:07:42Z

Add gre vport implementation. Most of gre protocol processing is pushed to gre module. It make use of gre demultiplexer therefore it can co-exist with linux device based gre tunnels. Signed-off-by: Pravin B Shelar Acked-by: Jesse Gross Signed-off-by: David S. Miller

openvswitch: Add tunneling interface.

2013-06-20T01:07:41Z

Add ovs tunnel interface for set tunnel action for userspace. Signed-off-by: Pravin B Shelar Acked-by: Jesse Gross Signed-off-by: David S. Miller

openvswitch: Simplify datapath locking.

2013-04-15T21:38:40Z

Currently OVS uses combination of genl and rtnl lock to protect datapath state. This was done due to networking stack locking. But this has complicated locking and there are few lock ordering issues with new tunneling protocols. Following patch simplifies locking by introducing new ovs mutex and now this lock is used to protect entire ovs state. Signed-off-by: Pravin B Shelar Signed-off-by: Jesse Gross
