Cause: During 4.5 to 4.6 upgrade, stricter security requirements of openssl versions included in 4.6 ovn-kubernetes components prevented the upgrade to complete successfully. Specifically the use of 1024 bit based DH params was disallowed on those openssl versions. Consequence: Upgrade of ovn-kuberentes and thus the cluster-network -operator does not progress to complete status and upgrade is stuck. Fix: Soften the openssl security requirements to allow the use of 1024 bit based DH params in ovn-kuberenetes componenets. Result: The use of 1024 bits based DH params with openssl no longer prevents the 4.5 to 4.6 upgrade to complete.
