selftests: openvswitch: Add version check for pyroute2

2023-10-25T10:16:15+00:00

commit 92e37f20f20a23fec4626ae72eda50f127acb130 upstream.

Paolo Abeni reports that on some systems the pyroute2 version isn't
new enough to run the test suite.  Ensure that we support a minimum
version of 0.6 for all cases (which does include the existing ones).
The 0.6.1 version was released in May of 2021, so should be
propagated to most installations at this point.

The alternative that Paolo proposed was to only skip when the
add-flow is being run.  This would be okay for most cases, except
if a future test case is added that needs to do flow dump without
an associated add (just guessing).  In that case, it could also be
broken and we would need additional skip logic anyway.  Just draw
a line in the sand now.

selftests: openvswitch: Fix the ct_tuple for v4

2023-10-25T10:16:15+00:00

commit 8eff0e062201e26739c74ac2355b7362622b7190 upstream.

The ct_tuple v4 data structure decode / encode routines were using
the v6 IP address decode and relying on default encode. This could
cause exceptions during encode / decode depending on how a ct4
tuple would appear in a netlink message.

Caught during code review.

selftests: openvswitch: Catch cases where the tests are killed

2023-10-25T10:16:15+00:00

commit af846afad5ca1c1a24d320adf9e48255e97db84e upstream.

In case of fatal signal, or early abort at least cleanup the current
test case.

selftests: openvswitch: add support for upcall testing

2023-04-17T07:12:33+00:00

The upcall socket interface can be exercised now to make sure that
future feature adjustments to the field can maintain backwards
compatibility.

selftests: openvswitch: add flow dump support

2023-04-17T07:12:33+00:00

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.

selftests: openvswitch: add interface support

2023-04-17T07:12:33+00:00

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.

selftests: openvswitch: adjust datapath NL message declaration

2023-04-13T17:01:23+00:00

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

2022-10-27T10:31:24+00:00

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.
