Date: Thu, 20 Jun 2024 08:55:55 -0400 Message-ID: <20240620125601.15755-2-aconole@redhat.com> In-Reply-To: <20240620125601.15755-1-aconole@redhat.com> References: <20240620125601.15755-1-aconole@redhat.com> Precedence: bulk X-Mailing-List: netdev@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 X-Scanned-By: MIMEDefang 3.0 on 10.30.177.15 X-Patchwork-Delegate: kuba@kernel.org 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.

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.

Since set() will use the key parsing routine, we also make sure to prepend it with an open paren, for the action parsing to properly understand it.

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.

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.
