Description Christopher Wawak 2021-04-09 14:09:04 UTC 
Description of problem:
When adding dns rules within an egress firewall, (seemingly random, more than 5), the firewall never applies successfully nor generates error messages indicating a failure.

This is reproduced on a clean OCP 4.7.4 cluster.

Version-Release number of selected component (if applicable):
OCP 4.7.4

How reproducible:
If you add more than 5 DNS rules, it's more likely to reproduce. It's been seen with one. Doesn't always reproduce the same result.

Steps to Reproduce:
1. Install 4.7.4 cluster on vmware ipi, designate OVN-Kubernetes
2. Apply egress firewall definition yaml

Actual results:
Firewall does not apply, leaving egress unsecured.

Expected results:
Firewall applies

We agreed that embargo is not necessary for this case.
The CVE-2021-3499 is public since now.
