kms: remove unused EncryptionConfigurationComputer interface

[bertinatto]

Preflight now always computes encryption configuration via EncryptionPlanner, so drop the noop interface and its parameter from controller constructors.

Summary by CodeRabbit

• Refactor
  • Simplified encryption controller configuration by removing an unnecessary compatibility dependency.
  • Encryption preflight processing now consistently uses the active encryption deployer and Kubernetes configuration.
• Tests
  • Updated encryption validation and integration tests to reflect the streamlined configuration flow.
  • Added coverage confirming encryption configuration is supplied during deployment scenarios.

Walkthrough

The encryption controller construction API no longer accepts EncryptionConfigurationComputer. KMS preflight configuration now always uses the planner-based path. Unit and end-to-end tests use the updated deployment wiring.

Changes

Encryption controller wiring

Layer / File(s)	Summary
Remove configuration computer from controller construction pkg/operator/apiserver/controllerset/apiservercontrollerset.go, pkg/operator/encryption/controllers.go	The public construction APIs and builder stop accepting, storing, and forwarding EncryptionConfigurationComputer.
Use planner-based preflight configuration pkg/operator/encryption/controllers/kms_preflight_controller.go	The controller removes the configuration computer abstraction, injection field, constructor parameter, and runtime fallback.
Update controller validation and integration pkg/operator/encryption/controllers/kms_preflight_controller_test.go, test/e2e-encryption/encryption_test.go	Tests remove fake computer fixtures and call-count checks, configure the encryption deployer and secret selector, and validate non-nil encryption configurations. End-to-end setup uses the updated constructor.

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

Merge Risk: 🔵 Low · up to 2cf24

The change removes an unused encryption-configuration dependency and updates its callers. The PR is mergeable with explicit owner follow-up because one test should directly confirm that deployment occurred.

Full details: Stable And Deterministic Test Names

Explanation

No failure condition is introduced. The changed Go test files use standard testing with Test... and t.Run, not Ginkgo title declarations. The t.Run titles come from static scenario strings. The diff removes one obsolete scenario and does not add dynamic values to any test title. Dynamic names, namespaces, timestamps, and hashes remain in test setup or assertions, not titles.

Full details: Test Structure And Quality

Explanation

PASS. The pull request does not modify Ginkgo tests. The changed KMS test uses standard Go table-driven t.Run with fake clients and direct sync calls. It adds no cluster resource creation or wait operation, and its changed assertion has a diagnostic message. The e2e test change only removes one constructor argument; it does not add setup, cleanup, or waiting logic. Existing e2e waits use wait.PollUntilContextTimeout, and existing cleanup remains unchanged.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request adds no new Ginkgo e2e tests. test/e2e-encryption/encryption_test.go only removes the NoopEncryptionConfigurationComputer argument from the existing TestEncryptionIntegration function. The other changed test is a Go unit test and only updates fixtures. No MicroShift-incompatible API, namespace, or unsupported feature is introduced by a new test.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

No new Ginkgo e2e tests were added. The only e2e change removes the controllers.NoopEncryptionConfigurationComputer{} constructor argument. The diff adds no It(), Describe(), Context(), or When() declarations, and it introduces no SNO-related multi-node assumptions.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The commit changes constructor parameters and encryption-configuration computation only. The patch introduces no affinity, topology spread, replica, PDB, node selector, toleration, taint, or topology logic. The KMS preflight pod template, deployer, and asset are unchanged. The existing master-node selector is therefore pre-existing and is not caused by this pull request.

Full details: Ote Binary Stdout Contract

Explanation

PASS: The PR only removes EncryptionConfigurationComputer parameters and updates related tests. The added-line scan found no fmt.Print*, log.Print*, klog output, RunSpecs, suite hooks, TestMain, main, or init code. The existing fmt.Printf calls are unchanged test logging helpers, and the existing klog call remains inside controller logic, not process-level setup. No stated OTE stdout contract violation was introduced.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

No new Ginkgo e2e test was added. The only e2e file change removes a constructor argument from test/e2e-encryption/encryption_test.go. The changed test files contain no It(), Describe(), Context(), or When() declarations, and the added lines contain no IPv4 or external-connectivity assumptions.

Full details: No-Weak-Crypto

Explanation

PASS. The pull request only removes EncryptionConfigurationComputer parameters, fields, fixtures, and call arguments, and activates the existing EncryptionPlanner path. The added diff contains no MD5, SHA1, DES, 3DES, RC4, Blowfish, ECB, custom cryptographic implementation, or non-constant-time secret/token comparison. The existing key generation uses crypto/rand with AES-256 and is unchanged by this pull request.

Full details: Container-Privileges

Explanation

PASS: The pull request changes five Go source/test files only. No manifest-like path changed, and no added or deleted line contains privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, or root settings. Existing privilege settings in unrelated manifests are not introduced by this pull request.

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

Explanation

PASS: The pull request adds no production logging. The only added logging-like calls are test assertions and a fake deploy error. The existing KMS hash log is unchanged, and the diff does not add passwords, tokens, API keys, PII, session IDs, hostnames, or customer data to logs.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert that deployment occurred.

The current guard checks deployedEncryptionConfig only when fakeDeployerInstance.deployed is true. If Deploy is skipped, this check passes. Add an expectedDeployed scenario field and assert the deployment call before checking the encryption configuration.
