openvswitch: Fix kernel panic on ovs_flow_free

2014-02-05T06:21:17Z

Both mega flow mask's reference counter and per flow table mask list should only be accessed when holding ovs_mutex() lock. However this is not true with ovs_flow_table_flush(). The patch fixes this bug. Reported-by: Joe Stringer Signed-off-by: Andy Zhou Signed-off-by: Jesse Gross

openvswitch: Per cpu flow stats.

2014-01-06T23:52:24Z

With mega flow implementation ovs flow can be shared between multiple CPUs which makes stats updates highly contended operation. This patch uses per-CPU stats in cases where a flow is likely to be shared (if there is a wildcard in the 5-tuple and therefore likely to be spread by RSS). In other situations, it uses the current strategy, saving memory and allocation time. Signed-off-by: Pravin B Shelar Signed-off-by: Jesse Gross

openvswitch: Change ovs_flow_tbl_lookup_xx() APIs

2014-01-06T23:51:41Z

API changes only for code readability. No functional chnages. This patch removes the underscored version. Added a new API ovs_flow_tbl_lookup_stats() that returns the n_mask_hits. Reported by: Ben Pfaff Reviewed-by: Thomas Graf Signed-off-by: Andy Zhou Signed-off-by: Jesse Gross

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: Simplify mega-flow APIs.

2013-10-04T07:18:30Z

Hides mega-flow implementation in flow_table.c rather than datapath.c. Signed-off-by: Pravin B Shelar 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
