Summary by CodeRabbit

  • Bug Fixes

    • KMS preflight deployments now generate unique remote key IDs and clear them during cleanup.
    • Repeated deployments with the same configuration retain a stable remote key ID.
  • Tests

    • Improved encryption tests now verify KMS preflight completion, freshness, configuration matching, healthy status, and availability of a remote key ID.
    • Added clearer validation and error reporting for KMS preflight status checks.

Walkthrough

The change makes KMS preflight remote key IDs unique per deployment or configuration. Encryption test helpers now read and validate operator preflight status, including success, configuration matching, remote key presence, and freshness.

Changes

KMS preflight validation

Layer / File(s) Summary
Remote key ID generation
pkg/operator/encryption/kms/preflight/always_succeed_deployer.go, test/e2e-encryption/encryption_test.go
The always-succeed deployer generates random hexadecimal remote key IDs and clears them during cleanup. The configurable test deployer includes the configuration hash in its remote key ID.
Preflight status assertions
test/library/encryption/assertion.go, test/library/encryption/helpers.go, test/library/encryption/scenarios.go
Helpers read operator status and decode the KMS preflight snapshot. Assertions poll for successful non-degraded status, matching configuration hashes, a populated remote key ID, and a fresh result. The KMS scenario checks the previous and updated snapshots.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 92940

The new preflight assertion can hide underlying read failures and report only a timeout, making diagnosis slower for certain access or connectivity errors. This is a bounded, localized risk that is mergeable with owner follow-up.

Explanation

PASS: The PR diff from merge-base 6a2a406 to HEAD changes five files, but it adds no Ginkgo title declarations (It, Describe, Context, When, or similar) and does not modify any test title. Random and configuration-derived remote key IDs appear only in deployer status data and assertion logic, not in test titles.

Full details: Test Structure And Quality

Explanation

The PR introduces an assertion without a meaningful failure message at test/library/encryption/scenarios.go:81: require.NoError(e, err) checks the preflight snapshot read but does not identify that operation or the operator. The new KMS polling assertion has a detailed message, and the polling has a one-minute timeout. The PR does not add resource creation without cleanup. The failure is limited to the new assertion message requirement.

Full details: Microshift Test Compatibility

Explanation

The check is not applicable. The pull request adds no Ginkgo It, Describe, Context, or When test. The repository search found no Ginkgo test declarations. It changes existing Go testing helpers and scenario functions. Although the new KMS helper queries operator.openshift.io resources, the stated check is limited to newly added Ginkgo e2e tests.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS. The pull request adds no new Ginkgo tests or Ginkgo declarations. It changes existing Go test helpers and KMS preflight assertions. The diff contains no assumptions about node counts, scheduling, affinity, failover, draining, scaling, or multi-endpoint load balancing. The added logic uses standard OpenShift APIs and operators, which are supported on SNO.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only KMS preflight test/deployer behavior and assertion helpers. The exact diff adds random remote-key IDs, status decoding, polling, and test assertions. It adds no manifests, replicas, affinity, topology spread, node selectors/affinity, tolerations, PDBs, or deployment-controller scheduling hooks. Therefore it introduces no topology scheduling constraint covered by this check.

Full details: Ote Binary Stdout Contract

Explanation

No changed code writes non-JSON data to stdout from process-level code. The PR changes deployer methods, test helpers, and test-case functions. Added logging uses testing.TB methods, not stdout. The existing fmt.Printf and fmt.Println calls are in test logging helpers and were not changed; they run during individual tests, which this check excludes. The existing init() only registers a scheme and remains unchanged.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS. The pull request adds no Ginkgo test nodes and introduces no IPv4 literals, IP parsing, URL construction, DNS lookup, public-host connection, image pull, or external download. The new assertion uses the Kubernetes dynamic client with cluster API resources. The vault.example.com and registry strings in test/e2e-encryption/encryption_test.go are pre-existing test fixtures and are not changed by this pull request; the configurable deployer does not connect to them.

Full details: No-Weak-Crypto

Explanation

PASS. The PR range changes five files and adds no MD5, SHA1, DES, 3DES, RC4, Blowfish, or ECB usage. The only cryptographic addition is crypto/rand for a random remote key ID, encoded with encoding/hex; this is not weak crypto or a custom crypto implementation. The new equality checks compare status values, configuration hashes, and remote key IDs, not secrets or tokens. No non-constant-time secret comparison was introduced.

Full details: Container-Privileges

Explanation

PASS. The PR changes only Go source and test files. The diff adds no Kubernetes or container manifests and contains no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, or allowPrivilegeEscalation settings. The changed code generates and checks KMS key IDs and reads operator status; it does not create privileged workloads or change container security settings.

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

Explanation

PASS: The pull request adds no logging of passwords, tokens, API keys, PII, session IDs, hostnames, or customer data. The new test failure message includes only KMS status fields: a configuration hash and RemoteKeyID. The API documentation defines RemoteKeyID as a non-cryptographic identifier for the KEK, and the configuration hash is computed as a hash. The always-succeed deployer generates a random synthetic identifier. No sensitive value is logged.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Return the dynamic-client read error.

The callback discards every Get error. A forbidden response, invalid resource mapping, or transport failure waits until timeout and hides the original cause. Return err from the callback.

Proposed fix
 		obj, err := dynamicClient.Resource(gvr).Get(ctx, name, metav1.GetOptions{})
 		if err != nil {
-			return false, nil
+			return false, err
 		}

As per coding guidelines and path instructions, “Never ignore error returns.”

I have one non-blocker comment. Other than that changes look good to me.

This is probably not important but wouldn't it be better to assert preflight before the AssertEncryptionConfig?

we need to make sure the preflight ran after setting the encryption mode/cfg which happens in the SetAndWaitForEncryptionType function. does it make sense ?

That is correct. But conceptually this should be in this order;

AssertKMSPreflightSucceededForOperator(ctx, e, clientSet, scenario.OperatorNamespace, previousPreflight)
AssertEncryptionConfig(e, clientSet, scenario.EncryptionConfigSecretName, scenario.EncryptionConfigSecretNamespace, scenario.TargetGRs)
