openvswitch: packet messages need their own probe attribtue

2015-01-14T21:49:44Z

User space is currently sending a OVS_FLOW_ATTR_PROBE for both flow and packet messages. This leads to an out-of-bounds access in ovs_packet_cmd_execute() because OVS_FLOW_ATTR_PROBE > OVS_PACKET_ATTR_MAX. Introduce a new OVS_PACKET_ATTR_PROBE with the same numeric value as OVS_FLOW_ATTR_PROBE to grow the range of accepted packet attributes while maintaining to be binary compatible with existing OVS binaries. Fixes: 05da589 ("openvswitch: Add support for OVS_FLOW_ATTR_PROBE.")

openvswitch: Add support for OVS_FLOW_ATTR_PROBE.

2014-11-10T02:58:44Z

This new flag is useful for suppressing error logging while probing for datapath features using flow commands. For backwards compatibility reasons the commands are executed normally, but error logging is suppressed. Signed-off-by: Jarno Rajahalme Signed-off-by: Pravin B Shelar

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: Fix the type of struct ovs_key_nd nd_target field.

2014-11-06T07:52:35Z

Should be the same as other IPv6 address fields. Current master produces sparse warnings without this change. Signed-off-by: Jarno Rajahalme Signed-off-by: Pravin B Shelar

openvswitch: Add basic MPLS support to kernel

2014-11-06T07:52:33Z

Allow datapath to recognize and extract MPLS labels into flow keys and execute actions which push, pop, and set labels on packets. Based heavily on work by Leo Alterman, Ravi K, Isaku Yamahata and Joe Stringer.

openvswitch: Add support for Geneve tunneling.

2014-10-06T04:32:21Z

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.

2014-10-06T04:32:20Z

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.

openvswitch: Add support for matching on OAM packets.

2014-10-06T04:32:20Z

Some tunnel formats have mechanisms for indicating that packets are OAM frames that should be handled specially (either as high priority or not forwarded beyond an endpoint). This provides support for allowing those types of packets to be matched. Signed-off-by: Jesse Gross Signed-off-by: Andy Zhou Acked-by: Pravin B Shelar Signed-off-by: David S. Miller

openvswitch: Add recirc and hash action.

2014-09-16T06:28:14Z

Recirc action allows a packet to reenter openvswitch processing. currently openvswitch lookup flow for packet received and execute set of actions on that packet, with help of recirc action we can process/modify the packet and recirculate it back in openvswitch for another pass. OVS hash action calculates 5-tupple hash and set hash in flow-key hash. This can be used along with recirculation for distributing packets among different ports for bond devices. For example: OVS bonding can use following actions: Match on: bond flow; Action: hash, recirc(id) Match on: recirc-id == id and hash lower bits == a; Action: output port_bond_a Signed-off-by: Andy Zhou Acked-by: Jesse Gross Signed-off-by: Pravin B Shelar

openvswitch: Allow each vport to have an array of 'port_id's.

2014-07-24T08:15:04Z

In order to allow handlers directly read upcalls from datapath, we need to support per-handler netlink socket for each vport in datapath. This commit makes this happen. Also, it is guaranteed to be backward compatible with previous branch. Signed-off-by: Alex Wang Acked-by: Thomas Graf Signed-off-by: Pravin B Shelar
