From f3b67e79edf76174b3fca6f8eb07e38671c72ff5 Mon Sep 17 00:00:00 2001 From: Brian Kane Date: Fri, 13 Feb 2026 21:53:48 +0000 Subject: [PATCH] feat: implement foundation - context cleanup and security (Part 1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements Part 1 of the policy refactor plan, establishing a clean and secure context structure for Application-scoped policies. Key Changes: 1. Security: Metadata Filtering - Added filterUserMetadata() to filter internal annotations/labels - Prevents policies from accessing system annotations (app.oam.dev/*, kubernetes.io/*, kubectl.kubernetes.io/*, etc.) - O(1) map-based filtering for performance 2. Explicit Context Fields - Added context.appName (instead of context.application.metadata.name) - Added context.namespace, context.appRevision, context.appRevisionNum - Added filtered context.appLabels and context.appAnnotations - All exposed via process.Context infrastructure 3. Controlled Application Spec Access - Added context.appComponents (components array only) - Added context.appWorkflow (workflow object only) - Added context.appPolicies (policies array only) - Prevents unintended access to full Application CR 4. Removed context.application - Completely removed to enforce explicit field access - Deleted cleanApplicationForPolicyContext() helper function - Forces security best practices 5. Removed context.prior - Simplified incremental policy feature (can be added back later) - Deleted associated test coverage Test Changes: - Deleted 3 test blocks relying on removed features - Fixed TTL test expectation (CRD default is -1, not 0) - Fixed WorkflowStep struct initialization - All tests passing Benefits: - ✅ Clean API with explicit fields - ✅ Security: No bypass to unfiltered metadata - ✅ Forces best practices - ✅ Simpler for policy authors 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../v1beta1/application/policy_transforms.go | 101 +--- .../application/policy_transforms_test.go | 531 ++++-------------- pkg/cue/process/handle.go | 7 + pkg/cue/process/keyword.go | 6 + 4 files changed, 162 insertions(+), 483 deletions(-) diff --git a/pkg/controller/core.oam.dev/v1beta1/application/policy_transforms.go b/pkg/controller/core.oam.dev/v1beta1/application/policy_transforms.go index 56548c7a3..9e5331eca 100644 --- a/pkg/controller/core.oam.dev/v1beta1/application/policy_transforms.go +++ b/pkg/controller/core.oam.dev/v1beta1/application/policy_transforms.go @@ -38,6 +38,8 @@ import ( utilfeature "k8s.io/apiserver/pkg/util/feature" "sigs.k8s.io/controller-runtime/pkg/client" + "k8s.io/apimachinery/pkg/apis/meta/v1/unstructured" + "github.com/oam-dev/kubevela/apis/core.oam.dev/common" "github.com/oam-dev/kubevela/apis/core.oam.dev/v1beta1" "github.com/oam-dev/kubevela/apis/types" @@ -48,7 +50,6 @@ import ( "github.com/oam-dev/kubevela/pkg/oam" "github.com/oam-dev/kubevela/pkg/utils/apply" oamprovidertypes "github.com/oam-dev/kubevela/pkg/workflow/providers/types" - "k8s.io/apimachinery/pkg/apis/meta/v1/unstructured" ) const ( @@ -60,12 +61,12 @@ const ( // and applies transforms from any Application-scoped PolicyDefinitions. // // Two-level caching strategy: -// 1.
