selftests: openvswitch: add support for upcall testing

2023-04-17T07:12:33Z

The upcall socket interface can be exercised now to make sure that future feature adjustments to the field can maintain backwards compatibility. Signed-off-by: Aaron Conole Signed-off-by: David S. Miller

selftests: openvswitch: add flow dump support

2023-04-17T07:12:33Z

Add a basic set of fields to print in a 'dpflow' format. This will be used by future commits to check for flow fields after parsing, as well as verifying the flow fields pushed into the kernel from userspace. Signed-off-by: Aaron Conole Signed-off-by: David S. Miller

selftests: openvswitch: add interface support

2023-04-17T07:12:33Z

Includes an associated test to generate netns and connect interfaces, with the option to include packet tracing. This will be used in the future when flow support is added for additional test cases. Signed-off-by: Aaron Conole Signed-off-by: David S. Miller

selftests: openvswitch: adjust datapath NL message declaration

2023-04-13T17:01:23Z

The netlink message for creating a new datapath takes an array of ports for the PID creation. This shouldn't cause much issue but correct it for future cases where we need to do decode of datapath information that could include the per-cpu PID map.

selftests: add openvswitch selftest suite

2022-10-27T10:31:24Z

Previous commit resolves a WARN splat that can be difficult to reproduce, but with the ovs-dpctl.py utility, it can be trivial. Introduce a test case which creates a DP, and then downgrades the feature set. This will include a utility 'ovs-dpctl.py' that can be extended to do additional tests and diagnostics.
