geneve: Add support to collect tunnel metadata.

2015-08-27T22:42:47+00:00

Following patch create new tunnel flag which enable tunnel metadata collection on given device. These devices can be used by tunnel metadata based routing or by OVS. Geneve Consolidation patch get rid of collect_md_tun to simplify tunnel lookup further. Signed-off-by: Pravin B Shelar Reviewed-by: Jesse Gross Acked-by: Thomas Graf Signed-off-by: David S. Miller

geneve: Make dst-port configurable.

2015-08-27T22:42:47+00:00

Add netlink interface to configure Geneve UDP port number. So that user can configure it for a Gevene device. Signed-off-by: Pravin B Shelar Reviewed-by: Jesse Gross Acked-by: Thomas Graf Acked-by: John W. Linville Signed-off-by: David S. Miller

bridge: Add netlink support for vlan_protocol attribute

2015-08-27T22:35:33+00:00

This enables bridge vlan_protocol to be configured through netlink. When CONFIG_BRIDGE_VLAN_FILTERING is disabled, kernel behaves the same way as this feature is not implemented. Signed-off-by: Toshiaki Makita Signed-off-by: David S. Miller

net: Introduce VRF related flags and helpers

2015-08-14T05:43:20+00:00

Add a VRF_MASTER flag for interfaces and helper functions for determining if a device is a VRF_MASTER. Add link attribute for passing VRF_TABLE id. Add vrf_ptr to netdevice. Add various macros for determining if a device is a VRF device, the index of the master VRF device and table associated with VRF device.

bridge: netlink: add support for vlan_filtering attribute

2015-08-10T20:36:43+00:00

This patch adds the ability to toggle the vlan filtering support via netlink. Since we're already running with rtnl in .changelink() we don't need to take any additional locks. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

vxlan: combine VXLAN_FLOWBASED into VXLAN_COLLECT_METADATA

2015-08-07T18:46:34+00:00

IFLA_VXLAN_FLOWBASED is useless without IFLA_VXLAN_COLLECT_METADATA, so combine them into single IFLA_VXLAN_COLLECT_METADATA flag. 'flowbased' doesn't convey real meaning of the vxlan tunnel mode. This mode can be used by routing, tc+bpf and ovs. Only ovs is strictly flow based, so 'collect metadata' is a better name for this tunnel mode.

bonding: add tlb_dynamic_lb netlink support

2015-07-31T22:35:55+00:00

tlb_dynamic_lb could be set only via sysfs, this patch allows it to be set via netlink. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

vxlan: expose COLLECT_METADATA flag to user space

2015-07-31T22:24:24+00:00

Two vxlan driver flags FLOWBASED and COLLECT_METADATA need to be set to make use of its new flow mode. The former already exposed. Expose the latter. Signed-off-by: Alexei Starovoitov Acked-by: Thomas Graf Signed-off-by: David S. Miller

vxlan: Flow based tunneling

2015-07-21T17:39:06+00:00

Allows putting a VXLAN device into a new flow-based mode in which skbs with a ip_tunnel_info dst metadata attached will be encapsulated according to the instructions stored in there with the VXLAN device defaults taken into consideration. Similar on the receive side, if the VXLAN_F_COLLECT_METADATA flag is set, the packet processing will populate a ip_tunnel_info struct for each packet received and attach it to the skb using the new metadata dst. The metadata structure will contain the outer header and tunnel header fields which have been stripped off. Layers further up in the stack such as routing, tc or netfitler can later match on these fields and perform forwarding. It is the responsibility of upper layers to ensure that the flag is set if the metadata is needed. The flag limits the additional cost of metadata collecting based on demand. This prepares the VXLAN device to be steered by the routing and other subsystems which allows to support encapsulation for a large number of tunnel endpoints and tunnel ids through a single net_device which improves the scalability. It also allows for OVS to leverage this mode which in turn allows for the removal of the OVS specific VXLAN code. Because the skb is currently scrubed in vxlan_rcv(), the attachment of the new dst metadata is postponed until after scrubing which requires the temporary addition of a new member to vxlan_metadata. This member is removed again in a later commit after the indirect VXLAN receive API has been removed. Signed-off-by: Thomas Graf Signed-off-by: Pravin B Shelar Signed-off-by: David S. Miller
