CORENET-7479: Add status.vrfName and shortNames to UDN/CUDN CRDs

[jluhrsen]

What this does

Adds status.vrfName and short names to the UserDefinedNetwork (UDN) and
ClusterUserDefinedNetwork (CUDN) CRDs that CNO ships in
bindata/network/ovn-kubernetes/common/001-crd.yaml.

Two edits, applied identically to both CRDs:

1. status.vrfName — a string (maxLength 15) added under status.properties
   (after conditions, preserving controller-gen's alphabetical ordering).
2. shortNames — udn on the UDN CRD and cudn on the CUDN CRD, added under
   spec.names.

Why

Upstream ovn-kubernetes PR openshift/ovn-kubernetes#6845 ("udn, cudn: publish the
derived VRF name in status.vrfName") landed in the 08-31 downstream merge
openshift/ovn-kubernetes#3426. The cluster-manager UDN controller
(cluster-user-defined-network-controller) now actively writes status.vrfName
on both UDN and CUDN objects.

Downstream, these CRDs are shipped by CNO, not by ovn-kubernetes. CNO's copy of
the schema did not have status.vrfName, so the API server rejected every status
apply-patch with:

failed to create typed patch object (... Kind=ClusterUserDefinedNetwork):
.status.vrfName: field not declared in schema

This caused the controller to error on every UDN/CUDN reconcile, failing ~19 e2e
jobs on the merge PR. This PR unblocks openshift/ovn-kubernetes#3426.

Mirrors upstream commits:

• e0ae49b4a — cudn API: add status.vrfName
• 418d3eed7 — udn API: add status.vrfName
• 272e9873b — fix: add short names for (c)udn

Scope / notes

• 5.1 (4.21 / master) only — must not be backported to 5.0.
• No feature gate, intentionally (decided that a feature gate is overkill here).
• These CRDs are hand-maintained in CNO (copied from upstream ovn-kubernetes); they
  are not produced by hack/update-codegen.sh, so hand-editing is correct.
  hack/update-codegen.sh runs clean and leaves this file untouched.

TODO for reviewer / human

⚠️ A suitable OCPBUGS Jira still needs to be prepended to the PR title and
commit so the jira-lifecycle bot is satisfied. None of the bugs listed on the
merge PR (OCPBUGS-114403 EVPN panic, OCPBUGS-112563 OpenTelemetry CVE,
OCPBUGS-99451 DNS pod role, OCPBUGS-99273 EgressIP host-cidrs) is the UDN
vrfName issue, and no dedicated OCPBUGS for this schema breakage was found — so
one should be identified or created rather than guessed.

Summary by CodeRabbit

• New Features
  • Added udn and cudn short names for quicker access to user-defined network resources.
  • Added status information showing the Linux VRF device name for primary networks.
  • VRF device names are limited to 15 characters.

Walkthrough

The CRDs now support udn and cudn short names. Their status schemas now include the Linux VRF device name for primary networks, limited to 15 characters.

Changes

UDN CRD metadata and status schema

Layer / File(s)	Summary
CRD aliases and VRF status fields bindata/network/ovn-kubernetes/common/001-crd.yaml	UserDefinedNetwork supports the udn short name. ClusterUserDefinedNetwork supports the cudn short name. Both status schemas define vrfName as a string with a maximum length of 15 characters.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 84a98

The PR adds status.vrfName and short names to the shipped UDN/CUDN CRDs. A corresponding bindata validation test is still needed to prevent these schema entries from drifting or being omitted, so merge readiness depends on adding that check or documenting a valid exception.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)

Full details: Pr Quality

Explanation

The PR is small and the description clearly explains what changes, why they are needed, the root cause, and the fix. It also includes upstream issue/PR references. However, this is a non-trivial functional CRD and bug-fix change, and the description has no “How to verify it” or “Testing” section identifying automated CNO CI jobs and platforms. The 22-line diff is reasonably scoped.

Full details: Commit Message Quality

Explanation

The PR contains one non-merge, self-contained commit. Its body is present and explains the API-server failure, controller impact, and intended fix. The subject is concise and descriptive, and it is not vague or a line-by-line changelog. However, the commit changes the scoped networking/ovn-kubernetes CRD, while the subject lacks an affected-component prefix. Repository history uses prefixes such as network:, bindata:, and ovn-kubernetes: for scoped changes.

Full details: Unit Tests For Go Changes

Explanation

The PR modifies the bindata YAML template bindata/network/ovn-kubernetes/common/001-crd.yaml by adding vrfName and CRD short names. The base-to-HEAD diff contains only this YAML file and no *_test.go changes. This matches the explicit failure condition.

Resolution

Add or modify a corresponding *_test.go file for the bindata template change. If tests are not valid because the change is trivial or existing coverage is sufficient, document that justification under How to verify it in the PR description. After all other pre-merge checks pass, use @coderabbitai ignore pre-merge checks to override.

Full details: E2e Tests For Feature Changes

Explanation

PASS: The pull-request diff contains only bindata/network/ovn-kubernetes/common/001-crd.yaml (+22 lines). It adds CRD short names and status.vrfName, but it does not add or modify any Go source file under pkg/ or cmd/. Therefore this check's E2E requirement is not applicable.

Full details: Rbac Least Privilege

Explanation

No RBAC rules changed. The pull request changes only bindata/network/ovn-kubernetes/common/001-crd.yaml, adding CRD shortNames and status.vrfName fields. The changed file contains no Role or ClusterRole declarations, and no added rules, verbs, or resources. The mutation and wildcard checks are therefore not applicable.

Full details: Docs For Feature And Behavior Changes

Explanation

PASS — The pull request changes only the shipped OVN-Kubernetes CRD manifest. It mirrors upstream CRD additions and fixes the schema mismatch that rejected controller status patches. It does not add CNO-specific control flow, architecture, or feature behavior. The check explicitly permits upstream CRD additions and bug fixes without documentation changes.

Full details: Stale Project Docs And Config

Explanation

The pull request changes only bindata/network/ovn-kubernetes/common/001-crd.yaml. It adds fields and short names to existing CRDs; it does not rename, move, or delete a path, code entity, operand, or architecture component. Searches found no UDN, CUDN, vrfName, or CRD-manifest references in .coderabbit.yaml, docs/**, or the repository AGENTS.md file. The existing .coderabbit.yaml path instruction for bindata/network/ovn-kubernetes/** remains accurate.

Full details: Go And Test Code Quality

Explanation

The pull request changes only bindata/network/ovn-kubernetes/common/001-crd.yaml. The committed diff contains no new or modified Go files, so none of the nine Go or test-code quality conditions applies.

Full details: Ai-Generated Code Smell

Explanation

PASS — The commit changes only the CRD YAML. The diff adds two short-name declarations and two status.vrfName schema fields with concise, functional API documentation. It adds no comments that merely restate code, no tests, no unnecessary executable logic, and no AI-tool or prompt references in the modified code. The repeated schema additions are required for the two separate CRDs.

Full details: Stable And Deterministic Test Names

Explanation

PASS: The pull request changes only bindata/network/ovn-kubernetes/common/001-crd.yaml. The patch adds CRD shortNames and status.vrfName schema fields. It adds no Ginkgo test files, test titles, or dynamic values in test titles.

Full details: Test Structure And Quality

Explanation

PASS — The pull request changes only bindata/network/ovn-kubernetes/common/001-crd.yaml. The exact diff adds CRD shortNames and status.vrfName schema fields. It adds or modifies no Ginkgo tests, It blocks, cluster operations, waits, or assertions, so this test-structure check is not applicable.

Full details: Microshift Test Compatibility

Explanation

PASS — the pull request adds only CRD YAML fields and short names in bindata/network/ovn-kubernetes/common/001-crd.yaml. The exact diff contains no new Ginkgo declarations or test files, so the MicroShift test compatibility check is not applicable.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The pull request changes only bindata/network/ovn-kubernetes/common/001-crd.yaml. The exact commit diff adds CRD short names and status.vrfName schema fields. It adds no Ginkgo e2e tests or other test code, so the SNO test-compatibility check does not apply.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only bindata/network/ovn-kubernetes/common/001-crd.yaml (+22/−0). The added lines define udn/cudn short names and the status.vrfName schema field for two CRDs. They add no deployments, controllers, replicas, affinity, topology spread, node selectors, tolerations, or PDBs. Therefore, the pull request introduces no scheduling constraint covered by this check.

Full details: Ote Binary Stdout Contract

Explanation

PASS: The pull request changes only bindata/network/ovn-kubernetes/common/001-crd.yaml, adding CRD schema fields and short names. The diff contains no Go code, OTE entry points, suite setup, or stdout/logging calls. Therefore, it introduces no process-level stdout write that can corrupt JSON output.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The pull request changes only the CRD YAML file. It adds udn, cudn, and status.vrfName; it adds no Ginkgo e2e tests or external network operations. The IPv6 and disconnected-network test compatibility check is therefore not applicable.

Full details: No-Weak-Crypto

Explanation

PASS: The PR changes only bindata/network/ovn-kubernetes/common/001-crd.yaml. The 22 added lines define CRD short names and the status.vrfName string schema. No added line contains MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, crypto, or cipher usage. The change contains no crypto implementation or secret/token comparison.

Full details: Container-Privileges

Explanation

PASS: The pull request changes only bindata/network/ovn-kubernetes/common/001-crd.yaml. The diff adds CRD short names and status.vrfName schema fields. It adds no container or pod security settings and no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, or allowPrivilegeEscalation entries.

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

Explanation

PASS — The pull request changes only a declarative CRD YAML file. The added lines define udn, cudn, and status.vrfName; they add no logging code or sensitive values. Searches of the added content found no passwords, tokens, API keys, PII, hostnames, session IDs, or customer data.

Full details: Title check

Explanation

The title clearly describes the CRD changes, uses the imperative mood, and is 64 characters long. However, it uses a CORENET issue key instead of the required OCPBUGS Jira key and does not prefix the affected component.

[tssurya]

what happens during upgrades? I bet the API upgrades first and then ovnkube components right? will the old objects be automatically updated for this new field? let's make sure we manually test upgrades from an old cluster with existing UDNs to this new patch and check ovnkube component logs to ensure no surprises.
Also is this field optional?

[tssurya]

is it that the vrfName field just appears for primary networks and is absent for secondary networks or that for secondary networks the value is empty?

On the relevant JIRA card please work with docs team to ensure this status condition shows up in OCPDOCS cc @JoeAldinger - lets not forget to update the API status for UDNs/CUDNs in product docs
