[v3,net-next,0/5] selftests: openvswitch: add flow programming cases

Message

Aaron Conole Aug. 1, 2023, 9:22 p.m. UTC

The openvswitch selftests currently contain a few cases for managing the
datapath, which includes creating datapath instances, adding interfaces,
and doing some basic feature / upcall tests.  This is useful to validate
the control path.

Add the ability to program some of the more common flows with actions. This
can be improved overtime to include regression testing, etc.

v2->v3:
1. Dropped support for ipv6 in nat() case
2. Fixed a spelling mistake in 2/5 commit message.

v1->v2:
1. Fix issue when parsing ipv6 in the NAT action
2. Fix issue calculating length during ctact parsing
3. Fix error message when invalid bridge is passed
4. Fold in Adrian's patch to support key masks

  selftests: openvswitch: add an initial flow programming case
  selftests: openvswitch: add a test for ipv4 forwarding
  selftests: openvswitch: add basic ct test case parsing
  selftests: openvswitch: add ct-nat test case with ipv4

FTR, this apparently requires an [un?]fairly recent version of
pyroute2. Perhaps you could explicitly check for a minimum working
version and otherwise bail out (skip) the add-flow tests.

Cheers,

I'll make sure to get a follow up out ASAP that includes some check for
supported version and will skip if not.  I will try to also include some
additional robustness checks.

Thanks Paolo!
