openvswitch: kernel datapath clone action

2018-07-08T02:13:25Z

Add 'clone' action to kernel datapath by using existing functions. When actions within clone don't modify the current flow, the flow key is not cloned before executing clone actions. This is a follow up patch for this incomplete work: https://patchwork.ozlabs.org/patch/722096/ v1 -> v2: Refactor as advised by reviewer.

openvswitch: add erspan version I and II support

2018-01-26T02:39:43Z

The patch adds support for openvswitch to configure erspan v1 and v2. The OVS_TUNNEL_KEY_ATTR_ERSPAN_OPTS attr is added to uapi as a binary blob to support all ERSPAN v1 and v2's fields. Note that Previous commit "openvswitch: Add erspan tunnel support." was reverted since it does not design properly. Signed-off-by: William Tu Acked-by: Pravin B Shelar Signed-off-by: David S. Miller

Revert "openvswitch: Add erspan tunnel support."

2018-01-15T19:33:16Z

This reverts commit ceaa001a170e43608854d5290a48064f57b565ed. The OVS_TUNNEL_KEY_ATTR_ERSPAN_OPTS attr should be designed as a nested attribute to support all ERSPAN v1 and v2's fields. The current attr is a be32 supporting only one field. Thus, this patch reverts it and later patch will redo it using nested attr.

OVS master and 2.8 branch has merged NSH userspace patch series, this patch is to enable NSH support in kernel data path in order that OVS can support NSH in compat mode by porting this.

openvswitch: reliable interface indentification in port dumps

2017-11-05T12:49:17Z

This patch allows reliable identification of netdevice interfaces connected to openvswitch bridges. In particular, user space queries the netdev interfaces belonging to the ports for statistics, up/down state, etc. Datapath dump needs to provide enough information for the user space to be able to do that. Currently, only interface names are returned. This is not sufficient, as openvswitch allows its ports to be in different name spaces and the interface name is valid only in its name space. What is needed and generally used in other netlink APIs, is the pair ifindex+netnsid. The solution is addition of the ifindex+netnsid pair (or only ifindex if in the same name space) to vport get/dump operation. On request side, ideally the ifindex+netnsid pair could be used to get/set/del the corresponding vport. This is not implemented by this patch and can be added later if needed.

License cleanup: add SPDX license identifier to uapi header files with a license

2017-11-02T10:20:11Z

Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.
