openvswitch: Add SCTP support

2013-08-26T21:03:13Z

This patch adds support for rewriting SCTP src,dst ports similar to the functionality already available for TCP/UDP. Rewriting SCTP ports is expensive due to double-recalculation of the SCTP checksums; this is performed to ensure that packets traversing OVS with invalid checksums will continue to the destination with any checksum corruption intact.

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: Use RCU lock for dp dump operation.

2013-08-23T23:37:59Z

RCUfy dp-dump operation which is already read-only. This makes all ovs dump operations lockless. Signed-off-by: Pravin B Shelar Signed-off-by: Jesse Gross

openvswitch: Use RCU lock for flow dump operation.

2013-08-23T23:37:59Z

Flow dump operation is read-only operation. There is no need to take ovs-lock. Following patch use rcu-lock for dumping flows. Signed-off-by: Pravin B Shelar Signed-off-by: Jesse Gross

openvswitch: Fix bad merge resolution.

2013-08-14T22:48:02Z

git silently included an extra hunk in vport_cmd_set() during automatic merging. This code is unreachable so it does not actually introduce a problem but it is clearly incorrect. Signed-off-by: Jesse Gross

openvswitch: Optimize flow key match for non tunnel flows.

2013-06-20T01:07:41Z

Following patch adds start offset for sw_flow-key, so that we can skip tunneling information in key for non-tunnel flows. 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: Copy individual actions.

2013-06-20T01:07:41Z

Rather than validating actions and then copying all actiaons in one block, following patch does same operation in single pass. This validate and copy action one by one. This is required for ovs tunneling patch. This patch does not change any functionality. Signed-off-by: Pravin B Shelar Acked-by: Jesse Gross Signed-off-by: David S. Miller

openvswitch: Simplify interface ovs_flow_metadata_from_nlattrs()

2013-06-14T22:09:12Z

This is not functional change, this is just code cleanup. Signed-off-by: Pravin B Shelar Signed-off-by: Jesse Gross

openvswitch: Immediately exit on error in ovs_vport_cmd_set().

2013-06-14T22:09:09Z

It is an error to try to change the type of a vport using the set command. However, while we check that this is an error, we still proceed to allocate memory which then gets freed immediately. This stops processing after noticing the error, which does not actually fix a bug but is more correct. Signed-off-by: Jesse Gross
