refactor(policy): move the tenant network guard to ValidatingPolicy - #5759
Kyverno is removing the current policy kind. Its replacement must preserve tenant isolation while letting existing applications reconcile normally.
What
Move the tenant network guard to the new policy kind. Existing policies can reconcile when their network rules stay unchanged; new or changed rules retain the boundary checks, and generated policies and rollout holds stay protected.
Keeps every refused shape, the DELETE guard on the generated floor names and
both applying-identity exemptions. The per-rule rows stay as per-check.yaml and
each check runs alone against them. Part of #4995.

Signed integration cd1a5751b38961c3a567e5651996ec0bef8383e4 incorporates main 21caad770dca36ebacc371d3461c179945bb9a85 and resolves all four conflicts. The shared admission driver retains both the network-policy kind and the newer team-resource kinds, and the action baseline preserves the other merged policy migrations.
The newer rollout-hold refusal needed explicit preservation in CEL. A real pinned-engine control first failed because the original migrated policy admitted the tenant's hold creation. The repaired policy passes 50 native controls: tenant create/update/delete, unchanged invalid old bodies, labelled and unlabelled namespaces, controller-name impersonation, exact-name/namespace boundaries, and the two platform actor exemptions. The five independent refusal families and their weakening controls still pass; the original 18 permitted and 78 refused tenant shapes remain unchanged. The unmanaged namespace now reports one explicit match-condition skip instead of disappearing through namespace-selector filtering.
Validation passes: 117 declarative Kyverno fixtures, the complete network-boundary regression, all four tenant-controller ownership families, fixture-evaluator regressions, policy-action baseline, ShellCheck, shfmt and gofmt. Local and production KSail validation each report 768 files validated; existing namespace-context and Helm value warnings remain. The rendered production infrastructure contains this ValidatingPolicy and its five denial checks. No production mutation was performed.
Fresh hosted CI and ordered current-head review are still required; the old review is stale. Keep this draft until those gates pass. Paired tenant-template PR devantler-tech/platform-tenant-template#274 follows this delivery; its current main-based admissibility failure is expected until then.
Readiness evaluated at cd1a5751b38961c3a567e5651996ec0bef8383e4. An isolated exact-head production render contains the intended ValidatingPolicy, fail-closed admission, Deny action and all five validations. The temporary evaluation worktree was clean and removed.
Independently read native tenant-policy execution: all 50 admission controls pass, including the ownership and refusal cases, and all four tenant admission families pass. The fixture execution reports 894 passed and zero failed. The manifest-validation job at that same head also passed. These observations exercise the policy with its real engine and establish the rendered effect; deployed acceptance remains the merge-group and post-merge readback.
All 56 reported checks are settled green/skipped, threads and non-thread findings are clear, the current-head Codex review is clean, the body contract passes, and the two-commit closing-keyword check reports zero findings. Fresh ownership reads found no holder or competing activity. The required aggregate and all three required workflows pass. code_quality setup is configured but its head verdict remains unverified; per the consumer merge policy, the ordinary protected merge API remains authoritative. No bypass or quality waiver is used. Paired tenant-template #274 follows after actual delivery.
Live observation during merge-group 41602267255 at e457df2814bf59aa2e0c9123b704b467e3384bac: two previously healthy tenant reconciliations began failing admission at approximately 08:40 UTC while their application artifact revisions remained unchanged. Both failures name the new tenant-network validation webhook: one ingress constraint and one egress constraint. The deployment step is still in progress. This is a production compatibility finding; the prior offline parity controls do not establish deployed acceptance. Let the ordinary deployment/recovery gates settle and diagnose before any requeue. Private readback is retained locally; no tenant policy was changed manually.

[P1] Stage compatibility for existing tenants before replacing the network guard
The current merge-group deployment at e457df2814bf59aa2e0c9123b704b467e3384bac has reached the new guard, but tenant reconciliation is now rejected during its normal dry-run, leaving the application layer unable to complete. Both affected tenant sources still report Ready. This is a deployed acceptance failure, despite the passing offline fixtures; it is not evidence that the public sites are down.
The existing public tenant manifests contain namespace selectors that these validations refuse: AS Coaching and Wedding app. The migration therefore needs a compatibility sequence for existing resources as well as the paired starter update. Add these supported inputs to the parity/admission controls and deliver their constrained replacements, with any platform-owned allowances, before retrying this migration. Keep the tenant boundary and required deployment checks intact.
Observed against PR head cd1a5751b38961c3a567e5651996ec0bef8383e4; production acceptance remains unverified while the merge-group deployment is running.
The compatibility gap is now reproduced offline with the deployed Kyverno 1.19.2 engine and only the committed fictional platform-author fixture. An UPDATE of its existing violating body under the tenant identity exits 0 with the current-main ClusterPolicy (pass: 2, fail: 0, error: 0, skip: 2). The reviewed CEL policy at cd1a5751b38961c3a567e5651996ec0bef8383e4 rejects both CREATE and an identical old/new UPDATE in the native engine. Its match constraints, conditions, variables, validations, actions and failure policy were independently matched against the observed policy. The upstream legacy validation handler explicitly skips a failed UPDATE when its prior response also fails and existing violations are allowed; Kyverno documents that behavior.
The currently green admission controls cover reserved ownership on unchanged invalid old bodies, but do not establish parity for an ordinary pre-existing violating policy. Preserve the reserved-name and rollout-hold refusals. Before another deployment, either migrate the affected consumers declaratively, or restore the established ordinary-update compatibility without granting new violations; prove the old/new decision difference with the same synthetic fixture. Do not requeue this head on unchanged evidence.
After the deterministic compatibility counterexample above and fresh exact-head/run/ownership reads, I submitted normal cancellation of merge-group 41602267255 at 09:04 UTC to let its existing always() recovery restore main. No force cancellation or direct policy/tenant mutation was used. Recovery and live reconciliation readback are still pending; do not requeue this head unchanged.

One blocking compatibility finding, reproduced with the deployed native engine and recorded inline. The unsuccessful deployment must recover before another trial.
Recovery readback at 09:19 UTC: the merge-group recovery restored the ClusterPolicy, removed the ValidatingPolicy, and both tenant Kustomizations returned to Ready (platform-live-health OK at 09:20 UTC). For the consumer-migration option above, I filed #5823. Tenant toFQDNs egress currently needs a tenant-authored kube-system DNS-proxy rule that the guard refuses, so dropping the tenants' DNS rules alone would break their FQDN egress. This comment only adds evidence; ownership of this PR stays with its active run.
Recovery is verified: the normally cancelled merge-group run 41602267255 completed, and its Heal Prod job succeeded. A fresh independent live-health check reports PLATFORM-HEALTH=OK. The compatibility finding remains unresolved at cd1a5751b38961c3a567e5651996ec0bef8383e4; that head is out of the merge queue and must be repaired and revalidated before another trial. The production recovery does not resolve the inline finding.
Unparked 2026-11-09. The #5846 dependency no longer holds: CI run 42491256713 on the 8 November head (f93c4bf3) failed only one check, the fixture-evaluation self-test, and that failure was this PR's own. Its "shorthand kinds" negative control still edited restrict-tenant-network-policies.yaml for a CiliumNetworkPolicy kind line, which no longer exists once the guard is a ValidatingPolicy, so the control broke nothing and reported exit 0.
Head c3a19589 merges current main and moves that control onto restrict-arc-retirement (the ExternalSecret kind of fence-credential-recreation), with a check that fails if the edit stops applying. The full self-test passes locally with Kyverno CLI 1.19.2, the version CI pins (35/35 cases).
2026-11-09 ~09:15Z. CI passed at c3a19589 (66 passed, 14 skipped). The CodeRabbit full review there found one Major security issue: a carved-out reserved key matched with NotIn/DoesNotExist beside an ordinary label escapes the namespace pin, because Cilium skips namespace injection for a selector naming a reserved: key. Fixed in 830f3c54 with two new attack fixtures; the thread is resolved.
2026-11-09 ~10:25Z.e78ffa53 also moves the controller-coverage test pin (78 → 80 refusals). CI is green there (Code Coverage passed on rerun after unrelated fixture timeouts). CodeRabbit refused the re-review (rate limited) and Codex and Bugbot are down, so a local review round was posted (review 5824390943, GREEN). No production CiliumNetworkPolicy uses the newly refused pattern (0 of 199). Promoted and enqueued head-pinned at e78ffa53.

The tenant network guard is a ValidatingPolicy on this branch, so the
CiliumNetworkPolicy kind edit no longer applied and the negative control
passed nothing. Break the ExternalSecret kind of restrict-arc-retirement
instead, and fail if the edit stops applying.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The tenant network policy changes from a Kyverno ClusterPolicy to a CEL-based ValidatingPolicy. The policy applies to managed ksail and kro namespaces and the exact staging-hold policy. It adds ingress, egress, default-deny, reserved-name, and plural specs checks, with an exception for unchanged-spec updates to ordinary policies. The shell and Kyverno tests are updated to cover the new policy and admission cases.
devantler-tech/platform#5344: It changes the managed namespace labels and generated policy names that this PR scopes and checks.
devantler-tech/platform#5411: It adds the staging-hold name protection that this PR carries into the ValidatingPolicy migration.
Merge Risk: Moderate · previous review c3a19
The new tenant network guard still lets a tenant write a selector that matches pods in other namespaces, because negative operators on the reserved kube-apiserver and ingress keys pass the checks. Fix this before relying on the guard for tenant isolation. The other open items are inaccurate fixture comments and have no runtime impact.

Full details: Title check
Explanation
The title names the main change: the tenant network guard moves to Kyverno's ValidatingPolicy kind. The raw summary confirms the core change converts the ClusterPolicy resource to a policies.kyverno.io/v1 ValidatingPolicy, and the objectives state the same intent. The title is concise, uses Conventional Commits form, and is specific enough for a teammate scanning history.
Full details: Description check
Explanation
The description states the purpose (Kyverno is removing the current policy kind, so the replacement must preserve tenant isolation and let existing applications reconcile). It also describes the change (moving the tenant network guard to the new policy kind, with unchanged rules reconciling and generated policies and rollout holds protected). It links the related issues and a merge-order constraint. It is related to the changeset and is not off-topic. The template comment and the generated-by line are boilerplate and do not affect the result.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Fix the comment: the policy does not use a namespaceSelector.
The policy is now a ValidatingPolicy. It scopes namespaces with a matchConditions expression that reads namespaceObject labels. The tenant-namespace-or-exact-staging-hold condition does this. The policy comments say a policy-level selector is deliberately avoided, because the exact rollout hold would then depend on mutable namespace labels. A maintainer who follows the comment will look for a selector that does not exist.
-# runs. The policy uses a namespaceSelector, so the CLI needs the namespace labels-# declared explicitly.+# runs. The policy reads namespace labels through namespaceObject in matchConditions,+# so the CLI needs the namespace labels declared explicitly.
Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Document that rule is a harness key, not a policy identifier.
The ValidatingPolicy has five unnamed spec.validations. The cnp-* values in rule: do not match any name in the policy. scripts/tests/test-restrict-tenant-network-policies.sh pairs each name with a validation by array index. It then strips rule before it runs kyverno test.
This file does not state that coupling. A maintainer who reorders or adds a validation gets a confusing failure from the shell test. Add a header comment that states the contract:
rule selects rows for one check.
The check order here must match the order of spec.validations.
📝 Proposed header comment
+# `rule` is a harness key, not a policy rule name. The ValidatingPolicy validations+# are unnamed. scripts/tests/test-restrict-tenant-network-policies.sh maps each+# `rule` value to a validation by position, so keep the order of the checks there+# equal to the order of spec.validations. The script strips `rule` before it runs+# `kyverno test`.

The same wording appears in the other changed kyverno-test.yaml files, so this comment covers those locations too. See the comment on tests/restrict-tenant-network-policies/kyverno-test.yaml.
The CIDR identity bypass is not reachable through these selectors.
For Cilium 1.20.4, cidr:, cidrgroup:, fqdn:, and bare or any: selectors receive the policy namespace constraint. The generated CIDR-group identities do not carry that namespace label, so the selector cannot match them. Adding these prefixes to broadSelectorKey is not required to close the claimed path.
179-185: Stability & Availability
The namespace controller’s DELETE can be denied, but the evidence does not establish that namespace teardown remains blocked. Kyverno has a separate, exempt cleanup path for the generated policies. The staging hold already had a DELETE guard at the PR base.
…ector keys
Cilium skips namespace injection for an endpoint selector that names a
`reserved:` key, so a `NotIn` or `DoesNotExist` expression on the
carved-out kube-apiserver/ingress keys beside an ordinary label selected
that label in every namespace. Require `In` or `Exists` for those keys on
both the ingress and egress side, add an attack fixture for each, and
correct the test comments that still described a namespaceSelector.

Scope: the whole PR had a CodeRabbit full review at c3a19589 (review 5823584107). Its one actionable finding was the reserved-key escape; this round reviews the two commits since then (830f3c54, e78ffa53) and re-checks that finding is closed.
What I checked:
The new constraint applies to every matchExpressions item whose key matches broadSelectorKey. Any such key outside the carve-out list is already refused, so in effect it binds only the carved-out kube-apiserver (and, for ingress, ingress) keys, in all three spellings, and allows only In and Exists.
The remaining positive forms stay inside the boundary: Exists or In on a reserved key requires the selected identity to carry that reserved label, so a selector that also names an ordinary label still selects only the reserved identity. In with a value other than the empty string selects nothing. A negative expression on an ordinary key beside a positive reserved key is likewise bounded by the reserved key.
An item with no key reads as '', which does not match broadSelectorKey, so it is judged by the existing constrained-selector checks and not let through by this one.
Both new attack fixtures (DoesNotExist on reserved:kube-apiserver for egress, NotIn on reserved:ingress for ingress) are refused by their own rule in per-check.yaml, and the existing kube-apiserver and ingress selector controls still pass both rules.
The two pinned summaries (test-restrict-tenant-network-policies.sh, test-tenant-controller-namespace-coverage.sh) moved from 78 to 80 refusals with passes unchanged at 18, which is exactly the two added attacks.
Live impact: none of the 199 CiliumNetworkPolicies on the production cluster uses a negative operator on these keys, so no deployed tenant policy is affected. Existing policies also stay admitted on unchanged updates.
Every check is green at this head. The one failure, 📊 Code Coverage, was fixture timeouts in the unrelated refresh-flux-ghcr-auth package (tracked by #5862) and passed on rerun.
What this means for a user: a tenant can still allow traffic to and from the API server and the Gateway, and can no longer use that allowance to reach workloads in other namespaces.

Why
Kyverno is removing the current policy kind. Its replacement must preserve tenant isolation while letting existing applications reconcile normally.
What
Move the tenant network guard to the new policy kind. Existing policies can reconcile when their network rules stay unchanged; new or changed rules retain the boundary checks, and generated policies and rollout holds stay protected.
