Richard Palethorpe	5d0b549049	feat(gallery): verify backend OCI images with keyless cosign (#9823) ... * feat(gallery): verify backend OCI images with keyless cosign Close a trust gap where a registry compromise or MITM could silently replace a backend image: the gallery YAML tells LocalAI which image to pull, but until now nothing verified the bytes came from our CI. Consumer (pkg/oci/cosignverify): - New package using sigstore-go to verify keyless-cosign signatures. - OCI 1.1 referrers API + new bundle format (no legacy :tag.sig). - Policy fields: Issuer / IssuerRegex / Identity / IdentityRegex / NotBefore. NotBefore is the revocation lever — keyless Fulcio certs are ephemeral so revocation is policy-side; advancing not_before in the gallery YAML invalidates every signature predating the cutoff. - TUF trusted root cached process-wide so N backends from one gallery do 1 fetch, not N. Plumbing: - pkg/downloader: ImageVerifier interface + WithImageVerifier option threaded through DownloadFileWithContext. Verification runs between oci.GetImage and oci.ExtractOCIImage, with digest pinning via pinnedImageRef to close the TOCTOU window. Skips the verifier's HEAD when the ref is already digest-pinned. - core/config: Gallery.Verification YAML block. - core/gallery: backendDownloadOptions builds the verifier from the policy; applied on initial URI, mirrors, and tag fallbacks. - core/gallery/upgrade: the upgrade path now routes through the same options builder. A regression Ginkgo spec pins this contract — without it, UpgradeBackend silently bypassed verification. - core/cli: --require-backend-integrity (LOCALAI_REQUIRE_BACKEND_INTEGRITY) escalates missing policy / empty SHA256 from warn to hard-fail. Producer (.github/workflows/backend_merge.yml): - id-token: write at job scope (PR-fork-safe via existing event gate). - sigstore/cosign-installer@v3 pinned to v2.4.1. - After each docker buildx imagetools create, resolve the manifest list digest and run cosign sign --recursive --new-bundle-format --registry-referrers-mode=oci-1-1 against repo@digest. --recursive signs the index and every per-arch entry, matching how the consumer resolves a tag to a platform-specific manifest before verifying. Rollout: backend/index.yaml has no `verification:` block yet, so this PR is backward-compatible — installs proceed with a warning until the gallery is populated. Strict mode is opt-in.

This leaked process state into the gallery package and made the flag impossible to override per-call or test without touching the env. Add RequireBackendIntegrity to ApplicationConfig (with a matching WithRequireBackendIntegrity AppOption) and thread the bool through every install/upgrade path: InstallBackend, InstallBackendFromGallery, UpgradeBackend, InstallModelFromGallery, InstallExternalBackend, ApplyGalleryFromString/File, startup.InstallModels. Worker subcommands gain the same env-bound flag on WorkerFlags so distributed-worker installs honor it consistently with the worker daemon path. Add a forbidigo lint rule against os.Getenv / os.LookupEnv / os.Environ to keep the env-leak pattern from creeping back. Existing offenders (p2p, config loaders, etc.) are baseline-grandfathered by the existing new-from-merge-base: origin/master setting; targeted path exclusions cover the legitimate cases — kong CLI entry points, backend subprocesses, system capability probes, gRPC AUTH_TOKEN inheritance, test gating env vars.

Ettore Di Giacinto	8ab0744458	feat: backend versioning, upgrade detection and auto-upgrade (#9315) ... * feat: add backend versioning data model foundation Add Version, URI, and Digest fields to BackendMetadata for tracking installed backend versions and enabling upgrade detection. Add Version field to GalleryBackend. Add UpgradeAvailable/AvailableVersion fields to SystemBackend. Implement GetImageDigest() for lightweight OCI digest lookups via remote.Head. Record version, URI, and digest at install time in InstallBackend() and propagate version through meta backends. * feat: add backend upgrade detection and execution logic Add CheckBackendUpgrades() to compare installed backend versions/digests against gallery entries, and UpgradeBackend() to perform atomic upgrades with backup-based rollback on failure. Includes Agent A's data model changes (Version/URI/Digest fields, GetImageDigest). * feat: add AutoUpgradeBackends config and runtime settings Add configuration and runtime settings for backend auto-upgrade: - RuntimeSettings field for dynamic config via API/JSON - ApplicationConfig field, option func, and roundtrip conversion - CLI flag with LOCALAI_AUTO_UPGRADE_BACKENDS env var - Config file watcher support for runtime_settings.json - Tests for ToRuntimeSettings, ApplyRuntimeSettings, and roundtrip * feat(ui): add backend version display and upgrade support - Add upgrade check/trigger API endpoints to config and api module - Backends page: version badge, upgrade indicator, upgrade button - Manage page: version in metadata, context-aware upgrade/reinstall button - Settings page: auto-upgrade backends toggle * feat: add upgrade checker service, API endpoints, and CLI command - UpgradeChecker background service: checks every 6h, auto-upgrades when enabled - API endpoints: GET /backends/upgrades, POST /backends/upgrades/check, POST /backends/upgrade/:name - CLI: `localai backends upgrade` command, version display in `backends list` - BackendManager interface: add UpgradeBackend and CheckUpgrades methods - Wire upgrade op through GalleryService backend handler - Distributed mode: fan-out upgrade to worker nodes via NATS * fix: use advisory lock for upgrade checker in distributed mode In distributed mode with multiple frontend instances, use PostgreSQL advisory lock (KeyBackendUpgradeCheck) so only one instance runs periodic upgrade checks and auto-upgrades. Prevents duplicate upgrade operations across replicas. Standalone mode is unchanged (simple ticker loop). * test: add e2e tests for backend upgrade API - Test GET /api/backends/upgrades returns 200 (even with no upgrade checker) - Test POST /api/backends/upgrade/:name accepts request and returns job ID - Test full upgrade flow: trigger upgrade via API, wait for job completion, verify run.sh updated to v2 and metadata.json has version 2.0.0 - Test POST /api/backends/upgrades/check returns 200 - Fix nil check for applicationInstance in upgrade API routes	2026-04-11 22:31:15 +02:00
