Summary

Adds 4 automated OTE test cases for WMCO TLS security profile enforcement (WINC-1988 / PR #4340):

  • OCP-90117: Verify default Intermediate TLS profile is loaded and ServiceMonitor exists
  • OCP-90118: Verify WMCO restarts when the APIServer TLS security profile changes
  • OCP-90119: Verify Modern profile enforces TLS 1.3 and refuses TLS 1.2 via openssl s_client
  • OCP-90120: Verify Custom profile with specific cipher suites is negotiated

All tests require StrictAllComponents adherence policy on apiserver/cluster. Tests skip gracefully on clusters that do not support the tlsAdherence field.

Implementation changes

  • Added TLS checker pod helpers using the cluster-local OpenShift tools image.
  • Generated checker pod names now use lowercase hexadecimal suffixes that comply with Kubernetes naming rules.
  • Updated restart detection to track the WMCO Pod UID/start time and the manager container restart count/container ID. This detects both Pod recreation and in-place container restarts.
  • Updated all WMCO and proxy restart checks to use the new restart-state helper.
  • Made the restart timeout message generic so it applies to TLS profile and proxy changes.
  • Avoided removing immutable tlsAdherence during cleanup; tests require StrictAllComponents to be preconfigured.
  • Restored an unset API server TLS profile as the explicit default Intermediate profile because the API server can reject removing the field after defaulting it.
  • Corrected the test name typo from tls-adherance to tls-adherence.

Test results

Using the rebuilt OTE binary and a cluster configured with tlsAdherence=StrictAllComponents:

  • OCP-90117: Passed
  • OCP-90118: Passed
  • OCP-90119: Passed
  • OCP-90120: Passed

The initial failures of OCP-90118, OCP-90119, and OCP-90120 were false negatives caused by checking only the Pod status.startTime. WMCO restarts the manager container in place, so the Pod is not recreated. After tracking the container restart state, the tests passed.

📝 Walkthrough

Walkthrough

The change adds API server TLS restoration, TLS checker pod, OpenSSL, and WMCO restart-state helpers. It adds four Windows end-to-end tests for Intermediate, Modern, Old, and Custom TLS profiles. The tests verify WMCO restarts, logs, protocol behavior, cipher negotiation, and the windows-exporter ServiceMonitor. Proxy tests now use the new restart-state helper.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to 21532

The TLS e2e coverage can be silently skipped after real profile-patch failures, or fail when a cluster already has the target TLS profile. Correct the setup and error handling before merge so the new tests reliably validate TLS enforcement.

Full details: Go Best Practices & Build Tags

Explanation

The pull request introduces four new ignored errors in ote/test/e2e/winc.go: TLS cleanup reads assign Output() errors to _ at the two deferred cleanup blocks. These errors can affect configuration-change detection and are neither checked nor logged. The new runTLSCheck helper also returns execInPod errors without adding context with fmt.Errorf(... %w). The changed OTE files do not introduce daemon or controller code, so the build-tag rules are not implicated. No new panic or nil dereference was found.

Resolution

Capture and handle each TLS configuration read error in both cleanup blocks. Log or otherwise report read failures instead of assigning errors to _. Handle the error returned by checkWMCORestarted in cleanup rather than discarding it. Update runTLSCheck to wrap execInPod failures with operation and endpoint context using fmt.Errorf("running TLS check against %s:%s: %w", host, port, err).

Full details: Test Structure And Quality

Explanation

The pull request adds many assertions without diagnostic messages. For example, ote/test/e2e/winc.go:2075, 2159, 2218, 2253, and 2337 use o.Expect(...).NotTo(o.HaveOccurred()) without context. The repository pattern and the check require messages that identify the failed cluster operation. The new TLS checker pod also has a cleanup gap: createTLSCheckerPod creates the pod at utils.go:1348, but the caller registers defer deleteTLSCheckerPod only after the helper returns. If the 120-second readiness wait at utils.go:1351 fails, the created pod remains. API-server restoration logs patch failures as warnings at utils.go:1296-1317, so cleanup can also leave the cluster-scoped TLS configuration changed. The added waits have finite timeouts, and the tests generally follow the repository's deferred-cleanup pattern, so those parts do not independently fail this check.

Resolution

Add a meaningful message to every new assertion, including each API-server get/patch, WMCO readiness/restart check, pod-IP lookup, oc exec TLS check, log check, and ServiceMonitor lookup. Register checker-pod cleanup immediately after pod creation, or make createTLSCheckerPod delete the pod when readiness fails; use a lifecycle hook such as AfterEach if appropriate. Make API-server restoration fail visibly or retry with a bounded timeout, and wait for WMCO readiness after restoration so a failed or incomplete cleanup cannot leave the cluster in the modified TLS state.

Full details: Microshift Test Compatibility

Explanation

The four added Ginkgo tests run inside Describe("[OTP][sig-windows] Windows_Containers", ...), which has no MicroShift protection tag or runtime guard. They directly access apiserver/cluster and tlsSecurityProfile/tlsAdherence from config.openshift.io, an unavailable OpenShift API group. Test 90117 also accesses servicemonitor from the unavailable monitoring API, and tests 90119/90120 use the new istag tools:latest helper from the unavailable image API. The test names contain [tls-adherence], not an [apigroup:...] or [Skipped:MicroShift] tag. MicroShift therefore reaches unsupported API calls instead of skipping.

Resolution

MicroShift compatibility notice: These tests use APIs that are not available on MicroShift. If this repository's presubmit CI does not already include MicroShift jobs, verify the tests with the serial job: /payload-job periodic-ci-openshift-microshift-release-4.22-periodics-e2e-aws-ovn-ocp-conformance-serial If the tests are intentionally not applicable to MicroShift, add an appropriate [apigroup:...] tag to the test or enclosing Describe (for example, [apigroup:config.openshift.io]), add [Skipped:MicroShift], or add an exutil.IsMicroShiftCluster() check followed by g.Skip(). Ensure the protection covers all four new tests.

Full details: No-Sensitive-Data-In-Logs

Explanation

The pull request adds raw TLS diagnostic output to the test logs. runTLSCheck executes openssl s_client with stderr merged into stdout, and the new e2e.Logf calls print that entire output for TLS 1.2, TLS 1.3, and custom-cipher checks. openssl s_client output can include peer certificate subject/SAN data. This endpoint uses the windows-exporter service certificate, whose configured server name is windows-exporter.openshift-windows-machine-config-operator.svc; therefore the new logs may expose an internal hostname. The raw-output logging is introduced by this pull request.

Resolution

Do not log the complete openssl s_client output. Parse the output and log only the required protocol, cipher, and pass/fail result. If diagnostic output is required, redact certificate blocks and subject, issuer, SAN, and other endpoint identity fields before logging. Apply this to all new TLS-output log statements.

- Line 1358: Update the restart validation around the startTime comparison to
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.

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:

  1. Which payload image has bash + openssl (tools imagestream?)
  2. Whether to refactor all linuxDebugImage usage or just this new test
  3. 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.

Re-running the OTE suite to get a completed signal on f43be1ff2 ("Adding skip to non TLS tests") — it hasn't had a finished aws-e2e-ote run since it was pushed (the prior run was aborted moments before, and the check has sat pending since). This also informs how we scope the new aws-e2e-ote-techpreview variant in openshift/release#84451 (whether we can drop the CI-level TEST_SKIPS and rely on this in-code non-TLS skip instead).

@rrasouli heads-up — the latest /test aws-e2e-ote on f43be1ff2 didn't reach the suite; it failed at the image build (~15m in) with a compile error: duplicate function declarations in test/e2e/utils.go:

test/e2e/utils.go:1699:6: getWMCOTimestamp redeclared in this block
	test/e2e/utils.go:1284:6: other declaration of getWMCOTimestamp
test/e2e/utils.go:1707:6: checkWMCORestarted redeclared in this block
	test/e2e/utils.go:1293:6: other declaration of checkWMCORestarted
make: *** [Makefile:111: build-tests-ext] Error 1
→ DockerBuildFailed: windows-machine-config-operator-test image

getWMCOTimestamp and checkWMCORestarted are each defined twice (lines 1284/1699 and 1293/1707) — looks like the "Adding skip to non TLS tests" commit duplicated them, likely from a rebase/merge. Removing the duplicate pair should let it compile; then a fresh /test aws-e2e-ote will give a real suite signal on the non-TLS skip. (make build-tests-ext locally reproduces it before pushing.)

Context on why this matters beyond this PR: openshift/release#84451 (the new aws-e2e-ote-techpreview variant) is trying to rely on this in-code non-TLS skip so it can drop the CI-level TEST_SKIPS (which currently zero-matches on master and lets the non-TLS LB [Slow] test flake on release-5.0). So once f43be1ff2 builds + this PR merges (and backports to release-5.0), #84451 can go green cleanly. Happy to re-run /test aws-e2e-ote here once you've pushed the fix.

@rrasouli one design question on the non-TLS skip, so we can wire up openshift/release#84451 (the aws-e2e-ote-techpreview variant) to match:

The g.Skip("[WINC-2016](https://redhat.atlassian.net/browse/WINC-2016): Skipping non-TLS test") calls in f43be1ff2 are unconditional (first line of each g.It). That means once this merges, the ~25 non-TLS specs will be skipped in the regular aws-e2e-ote job too — not just the techpreview/TLS run — which is a coverage regression on the main presubmit.

Could we make the skip conditional on an env var that only the techpreview job sets? Something like:

if os.Getenv("WINC_TLS_ADHERENCE_ONLY") != "true" {
    // run normally
} else {
    g.Skip("WINC-2016: Skipping non-TLS test")
}

Then #84451's techpreview stanza sets WINC_TLS_ADHERENCE_ONLY: "true", the regular job keeps full coverage, and the TLS job runs only 90117/90118. If you're happy with that approach, let's agree on the exact env-var name so I can set the matching value in #84451.

Two related notes for the techpreview wiring:

  • The TLS specs (90117/90118) are tagged [Serial][Disruptive]. So #84451 must not carry a \[Disruptive\] in TEST_SKIPS (it would skip the very tests we want). The plan there is to drop TEST_SKIPS entirely and rely on this in-code skip — the env-var gate above makes that clean.
  • The tests self-g.Skip if spec.tlsAdherence doesn't exist, so #84451's enable-tls-adherence step (which turns on the TLSAdherence gate via CustomNoUpgrade) stays — otherwise 90117/90118 would skip and the job would run zero tests. Worth confirming the release-5.0 backport pairs the gate support with the tests.

Happy to re-run /test aws-e2e-ote here once the compile fix + (optional) env-var gate are pushed.

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.

Establish the Intermediate profile before checking it.

This condition checks only tlsAdherence. If the cluster uses StrictAllComponents with a Modern, Old, or Custom profile, the test still expects VersionTLS12 and fails without testing the default profile.

Require an absent or Intermediate profile, or apply Intermediate and restore it after the test. The PR objective requires verification of the default Intermediate profile.

Make TLS restoration cleanup validate reconciliation.

The first two cleanup callbacks discard the (bool, error) result from checkWMCORestarted and the error from waitForDeploymentReady. The cleanup callbacks can therefore complete after a failed or incomplete WMCO restoration.

The direct deferred calls at lines 2199 and 2298 invoke restoreAPIServerTLS, which returns no error and only logs patch failures. They also do not wait for the asynchronous WMCO restart or deployment readiness that restoration can trigger.

Use one shared cleanup path for all four sites. It must propagate restoration errors, capture the WMCO baseline before restoration, require the restart check to succeed, and handle the deployment-readiness error. Keep the Windows-node readiness check in the second cleanup path.

Ensure each profile patch changes the TLS profile.

The Modern, Old, and Custom tests capture restart baselines before patching fixed profiles. They do not select a known alternate profile first. Restoration also restores the captured original profile, which can be the next test's target.

The SecurityProfileWatcher compares the effective profile with reflect.DeepEqual and invokes WMCO shutdown only when it changes. If the current profile already matches the target, the patch does not trigger a restart and checkWMCORestarted can fail after its six-minute poll. Apply a known alternate profile and wait for that transition before each target baseline, or otherwise ensure that every target differs from the current profile.

Do not convert profile patch failures into skips.

The Modern and Custom patches update only spec.tlsSecurityProfile; they do not request spec.tlsAdherence. Any authorization, validation, or API error is therefore reported as unsupported tlsAdherence, and the test skips its TLS checks.

Check adherence support before applying the profile. Then require each profile patch to succeed.
