📝 WalkthroughWalkthroughThe change adds WMCO restart detection and temporary Linux pod helpers for OpenSSL checks. It adds four Windows end-to-end tests for Intermediate, Modern, Old, and Custom TLS profiles. The tests update and restore API server TLS settings, verify WMCO restarts and logs, check protocol and cipher behavior, and validate the Suggested reviewers: Merge Risk: 🟡 Moderate · up to The PR adds TLS profile adherence tests, but the current implementation can report false-positive results, miss TLS command failures, and leave cluster TLS settings changed when cleanup fails; it also has bounded reliability issues for disconnected or IPv6 clusters.

reject an empty restart baseline instead of treating the newly available pod
timestamp as a restart. Return an error when startTime is unset, and assert
successful timestamp acquisition before each API server patch.
- Line 1385: Update the checker pod command in the test setup so it remains
running beyond the longest TLS specification, including the 20-minute timeout,
or persists until deferred cleanup; replace the five-minute sleep while
preserving the pod’s role as the target for the later openssl check.
- Line 1384: Update the new test pod definition near the image field so it uses
an image supplied by the cluster test payload or another guaranteed
cluster-local source instead of linuxDebugImage. Keep the pod’s existing
TLS-checking behavior unchanged.
- Line 1367: Update the error formatting in checkWMCORestarted to wrap pollErr
with the %w verb instead of formatting it with %v, preserving errors.Is and
errors.As inspection while keeping the existing context message.
- Line 1421: Update the OpenSSL command construction around the `cmd` assignment
to build the host-and-port target with `net.JoinHostPort(host, port)` instead of
formatting `%s:%s`, preserving the existing `tlsArg` and command behavior for
both IPv4 and IPv6 addresses.

Reject an empty restart baseline.
If startTime is empty, this comparison reports a restart when the existing pod timestamp becomes available. The restart assertions can then pass without a WMCO restart.
Return an error for an empty baseline. Assert successful timestamp acquisition before each API server patch.

Re: r3893603372 (disconnected cluster image concern)
The linuxDebugImage (registry.access.redhat.com/ubi9/ubi:latest) is used throughout the OTE test suite for Linux test pods (see winc.go lines 1109, 1807). This follows the existing pattern established in the codebase.
For disconnected clusters, the standard practice is to mirror required images including this UBI9 debug image. The test pod needs bash and openssl for TLS validation, which UBI9 provides.
If we need a cluster-local alternative, we'd need team guidance on:
- Which payload image has bash + openssl (tools imagestream?)
- Whether to refactor all linuxDebugImage usage or just this new test
- Cluster-local image discovery pattern to use
For now, this maintains consistency with existing OTE test patterns. Happy to update if there's a preferred cluster-local image source.
Add 4 automated test cases for WMCO TLS security profile enforcement: - OCP-90117: Verify default Intermediate TLS profile and ServiceMonitor - OCP-90118: Verify WMCO pod restarts on TLS profile change - OCP-90119: Verify Modern profile enforces TLS 1.3 via openssl - OCP-90120: Verify Custom profile with specific cipher suites Tests require StrictAllComponents adherence policy and skip gracefully on clusters that do not support the tlsAdherence field.

Summary
Adds 4 automated OTE test cases for WMCO TLS security profile enforcement (WINC-1988 / PR #4340):
All tests require StrictAllComponents adherence policy on apiserver/cluster. Tests skip gracefully on clusters that do not support the tlsAdherence field.
Helper functions added to utils.go: createTLSCheckerPod, deleteTLSCheckerPod, runTLSCheck.
