fix: return an error response for unresolved ExtensionRef by shreemaan-abhishek · Pull Request #481 · api7/api7-ingress-controller

shreemaan-abhishek · 2026-09-15T15:16:22Z

Type of change:

Bugfix

What this PR does / why we need it:

This change validates both the group and kind of ExtensionRef filters and accepts only apisix.apache.org/PluginConfig references.

Unsupported references and missing PluginConfig or Secret objects now set ResolvedRefs=False. The affected HTTPRoute or GRPCRoute rule remains programmed with an HTTP 500 response, while other valid rules remain active. Valid ExtensionRef filters are unchanged.

Unit coverage includes reference validation, status conditions, HTTPRoute and GRPCRoute translation, and ExtensionRef indexers. An end-to-end HTTPRoute case verifies both the condition and the 500 response.

Fixes #452

Breaking changes

Rules with invalid or unresolved ExtensionRef filters that previously forwarded requests without applying that filter now return HTTP 500. To migrate, use apisix.apache.org/PluginConfig and ensure the referenced PluginConfig and Secrets exist. Valid ExtensionRef filters are unchanged.

Pre-submission checklist:

Did you explain what problem does this PR solve? Or what new features have been added?
Have you added corresponding test cases?
Have you modified the corresponding document?
Is this PR backward compatible? If it is not backward compatible, please discuss on the mailing list first

No documentation changes are needed because this corrects route reference handling.

Summary by CodeRabbit

Bug Fixes
- Invalid, missing, or unresolved route extension references now produce clear resolution errors and HTTP 500 responses only for affected rules.
- Route processing continues for unaffected rules when an extension reference fails.
- Unsupported extension-reference groups and kinds are now correctly rejected.
- Plugin and secret lookup failures now preserve accurate route status and error reporting.
Tests
- Added coverage for extension-reference validation, resolution failures, rule-level fault responses, and end-to-end behavior.

Changes

ExtensionRef resolution

Layer / File(s)	Summary
Reference contracts and PluginConfig loading `internal/types/...`, `internal/controller/extensionref.go`, `internal/adc/translator/plugin_test.go`	PluginConfig references now require the supported API group and kind. PluginConfig and secret loading uses the provided context and returns typed errors for missing objects.
Route status and extension indexing `internal/controller/*route_controller.go`, `internal/controller/indexer/...`, `internal/controller/extensionref_resolution_test.go`	Route reconciliation records extension-reference failures in `ResolvedRefs`. HTTPRoute and GRPCRoute indexers use the shared reference predicate.
Per-rule translator responses `internal/adc/translator/...`, `test/e2e/gatewayapi/httproute.go`	Translation applies an HTTP 500 fault-injection response to the affected rule and continues processing other rules. Unit and end-to-end tests cover unsupported, missing, and unrenderable references.

Some unresolved references can return HTTP 500 while route status reports them as resolved, misleading operators and status consumers; this should be corrected before merge.

Full details: E2e Test Quality Review

Explanation

The PR adds one real E2E flow for an unsupported HTTPRoute ExtensionRef, including ResolvedRefs=False and an HTTP 500 response. However, the PR also changes unresolved ExtensionRef handling for GRPCRoute, while test/e2e/gatewayapi/grpcroute.go only covers a successful PluginConfig reference. Missing PluginConfig and Secret failures are covered only by fake-client or translator tests. This leaves critical failure paths without full API-to-data-plane coverage, which violates the scenario coverage requirement.

Resolution

Add E2E tests for unresolved GRPCRoute ExtensionRefs. Assert the route reports ResolvedRefs=False and that the gRPC request receives the configured error response. Add at least one E2E scenario for a missing PluginConfig or Secret, and verify that a valid rule remains active when another rule has the unresolved reference.

internal/controller/httproute_controller.go:247-255
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Propagate ExtensionRef read errors to ResolvedRefs. In both httproute_controller.go and grpcroute_controller.go, loadPluginConfigExtensionRef returns non-ReasonError PluginConfig or Secret read errors. The reconciliation branch sets Accepted=False but leaves backendRefErr nil, so SetRouteConditionResolvedRefs reports ResolvedRefs=True. Gateway API requires ResolvedRefs=False when a reference cannot be resolved. Assign the error to backendRefErr in this branch for both route kinds.

internal/controller/httproute_controller.go:247-255
🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Propagate ExtensionRef render failures to ResolvedRefs. loadPluginConfigExtensionRef stores PluginConfig without rendering it. renderPluginConfig rejects array-valued Config.Raw, and TranslateHTTPRoute converts that error into a per-rule HTTP 500 fallback while returning no error. Therefore processHTTPRoute succeeds, backendRefErr stays nil, and SetRouteConditionResolvedRefs reports ResolvedRefs=True. Propagate this render failure to the ResolvedRefs status input. The current non-ReasonError branch only sets Accepted=False and does not correct ResolvedRefs.
