Description Dan Winship 2021-04-13 12:53:17 UTC
New e2e test in 4.8:

[sig-network] Netpol [LinuxOnly] NetworkPolicy between server and client should enforce ingress policy allowing any port traffic to a server on a specific protocol [Feature:NetworkPolicy] [Feature:UDP] [Suite:openshift/conformance/parallel] [Suite:k8s]

This tests that

  kind: NetworkPolicy
  apiVersion: networking/v1
  metadata:
    name: allow-tcp
  spec:
    podSelector: {}
    ingress:
    - ports:
      - protocol: TCP

works. ie, "allow ingress on all TCP ports but not UDP"

This is a dumb feature and we never bothered to implement it in either openshift-sdn or ovn-kubernetes but there's a test for it now and it's easy to fix so it's better to implement it than to keep skipping the test.

(This needs to be fixed in both openshift-sdn and ovn-kubernetes, and then the e2e skip rules will need to updated in openshift/origin (for ovn-kubernetes) and openshift/kubernetes (for openshift-sdn).)
