From 0d7b270cb28e88e33824420130513389fe4e67e8 Mon Sep 17 00:00:00 2001 From: Antonio Ojea Date: Thu, 23 Jul 2026 14:02:34 +0000 Subject: [PATCH 01/43] feat(security): transition from static policies.yaml to dynamic relational SQL policy API - Replaced local file-based policies.yaml with centralized SQL tables (roles and bindings) in Postgres/SQLite on the Control Plane. - Exposed a REST API (/policies) to dynamically retrieve and update policies on the Hub. - Refactored the policy compiler to build Biscuit Datalog rules from relational DB snapshots locally on the node. - Added support for periodic policy sync interval configuration flag (--policy-sync-interval) on the node. - Gracefully handled OIDC callback local server shutdown to prevent TCP reset issues during enrollment. - Removed obsolete --policy-file flags, volumes, and ConfigMaps from all GKE template and kind development configurations. - Integrated automated policy seeding via background port-forward curl commands post-rollout in GitHub actions and local kind runner scripts. - Updated policy and control plane website guides to document the new JSON API and database model. - Fixed all golangci-lint issues across the codebase. - Verified that all unit, integration, and E2E test suites pass successfully. --- .github/k8s/sam-control-plane-template.yaml | 48 -- .github/workflows/deploy.yaml | 35 + api/datalog.go | 1 + api/datalog_test.go | 1 + api/policy.go | 36 -

Hub Policy Schema (`policies.yaml`) -Admins define central permissions by mapping OIDC roles to specific capabilities. - -* **`allowed_targets`**: Defines which logical groups or specific peers a user can route messages to, analogous to Active Directory security groups. Target definitions must be formatted as resolved facts (e.g., `group:`, `user:`, `email:`, `role:`, or `node:`). *Note: These are evaluated dynamically at the destination node using its own identity (see Section 3.1).* -* **`allowed_services`**: Defines the application-level tools or endpoints a user can access. Services use a strict `type://name` convention (e.g., `mcp://db-agent` or `inference://openrouter`). - * **Strict Namespaces**: There are no implicit fallbacks. `system://...` is used for internal services, `mcp://...` for node services, `inference://...` for AI models, etc. Service names must be valid domain labels (e.g. `value1.value2.value3`). - * **Wildcards**: SAM natively supports domain-level wildcards to build complex policies. The hub generates specific facts like `granted_service_exact($type, $name)`, `granted_service_prefix($type, $prefix)`, `granted_service_suffix($type, $suffix)`, `granted_service_all_in_type($type)`, or `granted_service_all_types()`. You can grant access to an entire type via `mcp://*`, allow prefix-based wildcard matching like `mcp://*.service.local` (which matches services ending in `.service.local`), suffix-based wildcard matching like `mcp://service.*` (which matches services starting with `service.`), or global access to everything via `*`. Note that arbitrary partial matches (e.g., `dev-*` or `*-prod`) are not supported because they do not align with domain boundaries and will fail DNS name validation. - * **MCP Namespace Convention**: The `mcp://` prefix (`api.MCPServicePrefix`) is the explicit convention for all Model Context Protocol targets. When remote nodes query local nodes for tool catalogs, if the local service is an MCP server, the proxy layer strictly enforces the authorization policy against the `mcp://` prefix. -> [!NOTE] -> The `*` global wildcard is a special case.

Hub Policy Configuration (REST API) +Admins manage central permissions dynamically via the Control Plane REST API. The policy database defines a set of **Roles** and **Bindings**. + +* **Roles**: Define specific capabilities (allowed destinations and services). + * `allowed_targets`: Defines which logical groups or specific peers a user can route messages to, analogous to Active Directory security groups. Target definitions must be formatted as resolved facts (e.g., `group:`, `user:`, `email:`, `role:`, or `node:`). *Note: These are evaluated dynamically at the destination node using its own identity (see Section 3.1).* + * `allowed_services`: Defines the application-level tools or endpoints a user can access. Services use a strict `type://name` convention (e.g., `mcp://db-agent` or `inference://openrouter`). + * **Strict Namespaces**: There are no implicit fallbacks. `system://...` is used for internal services, `mcp://...` for node services, `inference://...` for AI models, etc. Service names must be valid domain labels (e.g. `value1.value2.value3`). + * **Wildcards**: SAM natively supports domain-level wildcards to build complex policies. The hub generates specific facts like `granted_service_exact($type, $name)`, `granted_service_prefix($type, $prefix)`, `granted_service_suffix($type, $suffix)`, `granted_service_all_in_type($type)`, or `granted_service_all_types()`. You can grant access to an entire type via `mcp://*`, allow prefix-based wildcard matching like `mcp://*.service.local` (which matches services ending in `.service.local`), suffix-based wildcard matching like `mcp://service.*` (which matches services starting with `service.`), or global access to everything via `*`. + * **MCP Namespace Convention**: The `mcp://` prefix (`api.MCPServicePrefix`) is the explicit convention for all Model Context Protocol targets. +* **Bindings**: Map OIDC identities (sub/user, email, group) to specific Roles. + +### 2.1 Updating Mesh Policy +Admins POST policy JSON updates to the Control Plane `/policies` endpoint using the admin authorization token: + +```bash +curl -X POST \ + -H "Authorization: Bearer " \ + -H "Content-Type: application/json" \ + -d '{ + "roles": [ + { + "name": "data-scientist-role", + "allowed_targets": ["group:backend-nodes", "node:12D3KooW..."], + "allowed_services": ["mcp://db-agent", "inference://openrouter", "mcp://*"] + } + ], + "bindings": [ + { + "role": "data-scientist-role", + "members": ["group:data-science-team"] + } + ] + }' \ + http://:8080/policies ``` ## 3.

migrate local kind integration - Created a customizable Helm chart under charts/sam-mesh to easily deploy Control Plane (Hub), Router, Console, Database, and Dex. - Automated baseline policy seeding and router bootstrap token generation via a dedicated Kubernetes Job in the chart. - Cleaned up raw Kubernetes YAML manifests from development/kind/. - Configured development/kind/run.sh to boot the local cluster using the Helm chart, with dynamic local helm fallback binary check. - Parameterized node.template.yaml to leverage Helm-based service discovery. - Confirmed that Helm lints successfully and all E2E / integration test suites pass. --- charts/sam-mesh/Chart.yaml | 6 + charts/sam-mesh/templates/_helpers.tpl | 51 +++++++ charts/sam-mesh/templates/bootstrap-job.yaml | 138
