From 92513ca196125bbc8d01e412750cde0dcf4d914a Mon Sep 17 00:00:00 2001 From: weliang1 Date: Mon, 10 Aug 2026 22:36:40 -0400 Subject: [PATCH] test/networking: Add TLS Profile Compliance tests for networking components Add comprehensive e2e tests to verify TLS compliance for OpenShift networking components (multus-cni, ovn-kubernetes, cluster-network-operator, networking-console) across different TLS profiles and adherence policies. Test coverage: - Three TLS profile configurations: * Intermediate + LegacyAdheringComponentsOnly * Modern + LegacyAdheringComponentsOnly * Modern + StrictAllComponents - Networking components tested per profile: * multus-cni kube-rbac-proxy (port 9091) * cluster-network-operator metrics (port 9091) * networking-console plugin (port 9443) * ovn-kubernetes control-plane metrics (port 9108) * ovn-kubernetes node metrics (ports 9103, 9105) - Port-forward based TLS handshake verification using tls.Dial - Automatic cluster configuration and MCP rollout wait - Separate test cases for TLS 1.2 and TLS 1.3 where applicable Test behavior by profile and adherence policy: - Intermediate + LegacyAdheringComponentsOnly: Accept TLS 1.2 and 1.3 - Modern + LegacyAdheringComponentsOnly: Accept TLS 1.2 and 1.3 (legacy components) - Modern + StrictAllComponents: Enforce TLS 1.3 only, reject TLS 1.2 Implementation details: - Serial execution required due to cluster-wide TLS profile changes - Robust MCP rollout detection with retry logic - Component-specific port configurations matching actual deployments - Helper functions for TLS config, pod selection, and connection verification - Extended timeout (60s) for TLS handshake to handle slow environments - Suite tags: [sig-network][Feature:TLS][Serial] - Feature gate detection for proper test categorization Also update test/extended/util/tls.go: - Support port-forwarding to pods in addition to services - Increase connection timeout for TLS verification - Add pod namespace and name parameters to VerifyTLSConnection
