X-BeenThere: ovs-dev@openvswitch.org X-Mailman-Version: 2.1.30 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: dev@openvswitch.org, Simon Horman , linux-kernel@vger.kernel.org, Stefano Brivio , Eric Dumazet , linux-kselftest@vger.kernel.org, Jakub Kicinski , Paolo Abeni , Shuah Khan , "David S. Miller" Errors-To: ovs-dev-bounces@openvswitch.org Sender: "dev" The OVS module can operate in conjunction with various types of tunnel ports. These are created as either explicit tunnel vport types, OR by creating a tunnel interface which acts as an anchor for the lightweight tunnel support. This patch adds the ability to add tunnel ports to an OVS datapath for testing various scenarios with tunnel ports. With this addition, the vswitch "plumbing" will at least be able to push packets around using the tunnel vports. Future patches will add support for setting required tunnel metadata for lwts in the datapath. The end goal will be to push packets via these tunnels, and will be used in an upcoming commit for testing the path MTU.

Miller" Errors-To: ovs-dev-bounces@openvswitch.org Sender: "dev" Until recently, the ovs-dpctl utility was used with a limited actions set and didn't need to have support for multiple similar actions. However, when adding support for tunnels, it will be important to support multiple set() actions in a single flow. When printing these actions, the existing code will be unable to print all of the sets - it will only print the first. Refactor this code to be easier to read and support multiple actions of the same type in an action list.

There is a difference between the ODP format between tunnel(): the 'key' flag is not actually a flag field, so we don't support it in the same way that the vswitchd userspace supports displaying it.

MIMEDefang 3.0 on 10.30.177.12 Subject: [ovs-dev] [PATCH net-next v3 5/7] selftests: openvswitch: Support implicit ipv6 arguments. X-BeenThere: ovs-dev@openvswitch.org X-Mailman-Version: 2.1.30 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: dev@openvswitch.org, Simon Horman , linux-kernel@vger.kernel.org, Stefano Brivio , Eric Dumazet , linux-kselftest@vger.kernel.org, Jakub Kicinski , Paolo Abeni , Shuah Khan , "David S. Miller" Errors-To: ovs-dev-bounces@openvswitch.org Sender: "dev" The current iteration of IPv6 support requires explicit fields to be set in addition to not properly support the actual IPv6 addresses properly. With this change, make it so that the ipv6() bare option is usable to create wildcarded flows to match broad swaths of ipv6 traffic.

X-BeenThere: ovs-dev@openvswitch.org X-Mailman-Version: 2.1.30 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: dev@openvswitch.org, Simon Horman , linux-kernel@vger.kernel.org, Stefano Brivio , Eric Dumazet , linux-kselftest@vger.kernel.org, Jakub Kicinski , Paolo Abeni , Shuah Khan , "David S. Miller" Errors-To: ovs-dev-bounces@openvswitch.org Sender: "dev" The current pmtu test infrastucture requires an installed copy of the ovs-vswitchd userspace. This means that any automated or constrained environments may not have the requisite tools to run the tests. However, the pmtu tests don't require any special classifier processing. Indeed they are only using the vswitchd in the most basic mode - as a NORMAL switch. However, the ovs-dpctl kernel utility can now program all the needed basic flows to allow traffic to traverse the tunnels and provide support for at least testing some basic pmtu scenarios. More complicated flow pipelines can be added to the internal ovs test infrastructure, but that is work for the future. For now, enable the most common cases - wide mega flows with no other prerequisites. Enhance the pmtu testing to try testing using the internal utility, first. As a fallback, if the internal utility isn't running, then try with the ovs-vswitchd userspace tools. Additionally, make sure that when the pyroute2 package is not available the ovs-dpctl utility will error out to properly signal an error has occurred and skip using the internal utility.
