📝 WalkthroughWalkthroughUpdates Priority: ⬇️ Low Merge Risk: 🟡 Moderate · up to Strictly adhered cluster profiles can cause operator connections to use weak TLS settings. Restore the TLS 1.2 and approved-cipher floor before merging. Important Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional. ❌ Failed checks (1 error)
✅ Passed checks (14 passed)
Full details: No-Weak-CryptoExplanation The pull request introduces SHA-1 cipher usage. The new test configures Resolution Reject custom or built-in profiles that use SHA-1 or other prohibited algorithms before creating the TLS configuration. Require at least TLS 1.2 and allow only approved secure cipher suites, falling back to the Intermediate profile when validation fails. Update the test to use a secure cipher and TLS version.

Summary
Add a shared
ResolveTLSConfigentry point for OpenShift operators. It resolves the cluster TLS profile and adherence policy into a reusableConfigResultcontaining the TLS configuration function and resolved metadata.Design
APIServerresource once so the TLS profile and adherence policy always come from the same resource version.NoOpinionorLegacyAdheringComponentsOnly.Oldprofile and custom profiles using TLS 1.0 or TLS 1.1.SecurityProfileWatchereven when an invalid version requires the applied TLS configuration to fall back to Intermediate.APIServerAvailable=false; a missing singleton or transient error keeps it true so a watcher can recover when the resource becomes available.APIServerAvailableso consumers can decide whether to registerSecurityProfileWatcher.Why
Operators need consistent TLS behavior without duplicating APIServer lookup, adherence-policy handling, profile resolution, error classification, and fallback logic. Strict adherence means the component follows the administrator's selected cluster profile, including legacy settings for environments that still require them. Reading one APIServer snapshot prevents profile and adherence values from being combined across concurrent updates. Preserving the observed profile also prevents a malformed configuration from causing the watcher to restart the process repeatedly.
Testing
make testmake lintmake verifyOldand TLS 1.1 profiles, malformed-version fallback, watcher-safe profile state, transient errors, missing singleton recovery, and fail-closed permission or unexpected errors.
