openvswitch: Add support for OVS_FLOW_ATTR_PROBE.

2014-11-10T02:58:44+00:00

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.

openvswitch: Extend packet attribute for egress tunnel info

2014-11-10T02:58:44+00:00

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.

openvswitch: Fix the type of struct ovs_key_nd nd_target field.

2014-11-06T07:52:35+00:00

Should be the same as other IPv6 address fields.

Current master produces sparse warnings without this change.

openvswitch: Add basic MPLS support to kernel

2014-11-06T07:52:33+00:00

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.

2014-10-06T04:32:21+00:00

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.

2014-10-06T04:32:20+00:00

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.

2014-10-06T04:32:20+00:00

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.

openvswitch: Add recirc and hash action.

2014-09-16T06:28:14+00:00

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

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

2014-07-24T08:15:04+00:00

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.

openvswitch: Avoid assigning a NULL pointer to flow actions.

2014-05-22T23:27:34+00:00

Flow SET can accept an empty set of actions, with the intended
semantics of leaving existing actions unmodified.  This seems to have
been brokin after OVS 1.7, as we have assigned the flow's actions
pointer to NULL in this case, but we never check for the NULL pointer
later on.  This patch restores the intended behavior and documents it
in the include/linux/openvswitch.h.
