Summary by CodeRabbit

  • Bug Fixes

    • Corrected security-group cleanup so only the intended group reference is revoked, preserving other node security-group rules.
    • Improved handling of instances that no longer exist, allowing lifecycle checks to return the correct status instead of reporting unexpected errors.
    • AWS API error metrics now reflect final failures after retries, avoiding duplicate counts for transient errors.
  • Maintenance

    • Updated Kubernetes and supporting dependencies to newer releases.
    • Extended load balancer cleanup retry windows to improve end-to-end test reliability.

hugolevino and others added 9 commits June 30, 2026 21:00
buildSecurityGroupRuleReferences inserted the whole ec2 IpPermission when
any one of its UserIdGroupPairs referenced the security group being removed.
removeOwnedSecurityGroups then passed that consolidated permission straight
to RevokeSecurityGroupIngress, so a single revoke removed every pair sharing
the same protocol/port tuple. EC2 commonly consolidates the node/cluster SG's
all-traffic (-1) self-reference and the controller's LB->node rule into one
IpPermission, so cleaning up the managed SG on a CLB managed->BYO SG
transition also revoked the self-reference and broke cross-node pod traffic.

Narrow the linked permission to only the matching UserIdGroupPair (and clear
the CIDR / prefix-list dimensions), matching the single-pair revoke pattern
already used by the CLB delete and NLB paths, so unrelated pairs such as the
node SG self-reference are preserved.

Hi @cloud-team-rebase-bot[bot]. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Walkthrough

The change updates Kubernetes and Go dependencies, corrects controller configuration, normalizes missing AWS instance errors, records terminal AWS API metrics, narrows security-group revocations, and extends NLB cleanup retries.

Changes

AWS provider and platform updates

Layer / File(s) Summary
Dependency and controller configuration
go.mod, tests/e2e/go.mod, pkg/controllers/tagging/tagging_controller_wrapper.go
Dependencies move to Kubernetes 1.37 releases. The tagging controller reads NodeMonitorPeriod from NodeLifecycleController.
Instance lifecycle error handling
pkg/providers/v1/aws.go, pkg/providers/v1/instances_v2.go, pkg/providers/v1/instances_v2_test.go
AWS instance-not-found responses map to cloudprovider.InstanceNotFound. Instance checks return (false, nil) for deleted instances and preserve other errors.
Terminal AWS API metrics
pkg/providers/v1/aws_metrics.go, pkg/providers/v1/aws_sdk.go, pkg/providers/v1/aws.go, pkg/providers/v1/aws_api_metrics_test.go
Metrics use Finalize middleware before SDK retries and count terminal HTTP failures once. Tests cover retries, successful calls, and missing HTTP responses.
Security-group revocation narrowing
pkg/providers/v1/aws_loadbalancer.go, pkg/providers/v1/aws_loadbalancer_test.go
Revocation permissions contain only the matched UserIdGroupPair. Tests cover consolidated permissions with node security-group self-references.
End-to-end cleanup retry windows
tests/e2e/loadbalancer.go
NLB cleanup retries use a six-minute timeout with ten-second intervals in three scenarios.

Full details: Docstring Coverage

Explanation

Docstring coverage is 35.71% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 14 functions across 10 files. (2 skipped: 2 unsupported.)

Full details: Stable And Deterministic Test Names

Explanation

No changed Ginkgo test title violates the check. The PR adds only Go testing subtests (t.Run), not Ginkgo titles. In tests/e2e/loadbalancer.go, the diff changes only cleanup timeout values. The existing Describe, Context, and It(tc.name, ...) lines are identical in origin/main and HEAD, and their case names are static literals.

Full details: Test Structure And Quality

Explanation

The changed Ginkgo code is limited to three existing BYO security-group cleanup callbacks in tests/e2e/loadbalancer.go. Each uses DeferCleanup and an explicit Eventually timeout, changed from 2 minutes to 6 minutes with 10-second polling. No new It, BeforeEach, or AfterEach blocks were introduced. The other changed test files use standard Go testing and testify, not Ginkgo. Cluster setup and cleanup code was not newly introduced, and no new indefinite wait or missing assertion message was found.

Full details: Microshift Test Compatibility

Explanation

PASS — The PR adds no new Ginkgo e2e tests. The only changed e2e source file, tests/e2e/loadbalancer.go, changes three BYO security-group cleanup timeouts from 2 minutes/5 seconds to 6 minutes/10 seconds. The diff adds no It, Describe, Context, or When registrations and references no MicroShift-unavailable APIs or namespaces.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The PR adds no new Ginkgo e2e declarations. The added tests are standard Go unit tests (func Test...) under pkg/providers/v1. The only e2e change updates existing BYO security-group cleanup retry timing in tests/e2e/loadbalancer.go; existing Describe/It registrations are unchanged. Therefore, no SNO multi-node compatibility failure condition is introduced.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS. The non-vendored PR diff changes Go modules, AWS provider behavior, test code, and one controller wrapper. No deployment manifest changed. The only controller change switches the node monitor period configuration; it does not create or modify pod scheduling fields. The changed e2e deployment helper only changes security-group cleanup timeouts. Diff scans found no added affinity, topology spread, toleration, node selector, replica, PDB, or control-plane scheduling constraints.

Full details: Ote Binary Stdout Contract

Explanation

No OTE stdout contract failure was introduced. The repository has no openshift-tests or OTE binary integration. tests/e2e/suite_test.go and both main.go entrypoints are unchanged. The changed e2e source only adjusts cleanup timeouts. The upgraded Ginkgo direct fmt.Println additions are in its CLI packages, not the linked test suite; FdOutput is disabled by default. The changed application code adds no process-level stdout writes.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

No new Ginkgo e2e test was added. The only non-vendored e2e change modifies three BYO security-group cleanup timeouts in tests/e2e/loadbalancer.go. The existing Ginkgo tests and existing URL construction are unchanged. The other added tests use Go's standard testing package and are not e2e tests. Therefore, no IPv4 or external-connectivity failure condition was introduced.

Full details: No-Weak-Crypto

Explanation

PASS: The PR does not introduce weak-crypto usage or custom cryptography. The changed application code contains no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, or secret/token comparison logic. Existing MD5 and SHA1 call sites in pkg/controllers/tagging/tagging_controller.go and pkg/providers/v1/aws_loadbalancer.go are unchanged. The golang.org/x/crypto version bump does not add weak packages to the production vendor tree; legacy Blowfish/SSH code in the e2e vendor tree was already present before the PR.

Full details: Container-Privileges

Explanation

No privilege condition was introduced by this PR. The PR changes no deployment manifest, Dockerfile, or container build file. Added non-vendored source lines contain no privilege-related settings. Existing hostNetwork: true settings remain unchanged. Updated vendored Kubernetes test manifests contain pre-existing privileged or host-namespace settings, but their added diff lines contain none of the checked conditions.

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

Explanation

No sensitive-data logging was introduced. The production diff adds no logging calls or sensitive logging fields; the only non-vendor matches are test error fixtures. pkg/providers/v1/log_handler.go, which logs AWS request parameters, is unchanged. The AWS changes add terminal status metrics and do not log request data. The vendored consistency-detector diff logging existed before this PR and remains opt-in for CI use.

AWS NLB ENIs can take several minutes to detach after the load balancer
is removed. The previous 2-minute Eventually timeout for BYO security
group deletion appears occasionally insufficient in loaded CI environments.
Increase the timeout to 6 minutes to cover the realistic ENI detachment tail,
and bump the poll interval from 5s to 10s accordingly.
…ach-timeout

e2e: increase BYO SG deletion timeout from 2 to 6 minutes
…s_total

cloudprovider_aws_api_response_status_total was recorded by a Deserialize
middleware, which runs inside the SDK retry loop and reads the HTTP status from
out.RawResponse. It therefore incremented once per attempt: a call that received
a 5xx/throttle response and then succeeded on retry was still counted as an
error, so the metric over-counted transient responses the SDK recovered from and
could not be used to measure the actual AWS API error rate.

Move the middleware to a Finalize step inserted before the SDK Retry middleware
so it wraps the whole retry loop and runs once per logical call, recording the
status only of terminal errors (read from the terminal *awshttp.ResponseError).
A response that is retried and then succeeds is no longer counted. The metric
name and {service, operation, status_code} labels are unchanged.

Attach the middleware via a shared addAWSAPIMetricsMiddleware option at the two
existing call sites (default clients and the STS client).

Assert that the 400 response uses one attempt.

This test verifies the metric count but not its “first attempt” claim. The metric still increments once if the retryer incorrectly retries the 400 response.

Retry InvalidInstanceID.NotFound before returning cloudprovider.InstanceNotFound.

EC2 can return this error during eventual consistency after RunInstances, even when the instance will become visible. When a node has no provider ID, InstanceExists can convert this sentinel to (false, nil) and treat a live node as absent. Use a bounded retry before mapping the error.

In `@pkg/providers/v1/aws.go` around lines 3528 - 3532, Add a bounded retry for
IsAWSErrorInstanceNotFound(err) in the DescribeInstances flow before returning
cloudprovider.InstanceNotFound, allowing eventual consistency after RunInstances
to resolve. Preserve the existing sentinel mapping after retries are exhausted,
and use the surrounding instance lookup/retry mechanism rather than introducing
unbounded polling.

Don't read LDFLAGS from env, in brew we set C specific flags that cause
the build to break.
Adds .spec file for building the ecr credential provider.

We build this using brew, and tooling from ART. This means we don't need
to worry about setting env vars (e.g OS_GIT_VERSION) and where Source0
is set.
- Create load balancers according to the Kubernetes Service API

Changing the IP address type would invalidate the target group name,
because you cannot have an IPv4 and IPv6 target for the same
port/protocol set.
