Mrunal Patel 084505425b feat(auth): add OIDC/Keycloak authentication with RBAC and scope-based permissions (#935)
* feat(auth): add OIDC/Keycloak authentication with RBAC

Add OAuth2/OIDC authentication to the gateway server with role-based
access control, CLI login flows, and full deployment plumbing.

Server: JWT validation against configurable OIDC issuer (oidc.rs),
JWKS key caching with TTL and rotation handling, method classification
(unauthenticated/sandbox-secret/dual-auth/bearer), identity extraction
with provider-agnostic Identity type, and RBAC enforcement via
AuthzPolicy with configurable admin/user roles and auth-only mode.

CLI: browser-based Authorization Code + PKCE flow, Client Credentials
flow for CI/automation, token storage with refresh, gateway add/login/
logout commands, OIDC bearer token injection over mTLS transport,
discovery endpoint for auto-configuration.

Security: sandbox-secret scope restriction on UpdateConfig (policy
sync only), anti-spoofing header stripping, dual-auth fallthrough
from sandbox-secret to Bearer token.

Deployment: OIDC config wired through DeployOptions, Docker env vars,
Helm values/templates, HelmChart manifest, cluster-entrypoint.sh, and
bootstrap scripts. Keycloak dev server script with pre-configured
realm (test users, roles, PKCE client, CI client).

Tested with Keycloak. The roles claim path and role names are
configurable to support other OIDC providers.

* feat(auth): add OAuth2 scope-based fine-grained permissions

Add opt-in scope enforcement on top of existing OIDC role-based access
control. When --oidc-scopes-claim is set, the server extracts scopes
from the JWT and checks them per-method against an exhaustive scope map.

Scopes: sandbox:read, sandbox:write, provider:read, provider:write,
config:read, config:write, inference:read, inference:write, and
openshell:all (wildcard). Methods not in the scope map require
openshell:all. Scopes layer on top of roles and cannot escalate
privilege. Auth-only mode (empty role names) still enforces scopes
when enabled.

Server: scopes_claim in OidcConfig, scope extraction from JWT
(space-delimited and JSON array formats), standard OIDC scope
filtering, scope check in AuthzPolicy after role check.

CLI: --oidc-scopes on gateway add/start stored in metadata and
consumed by gateway login, --oidc-scopes-claim on gateway start
forwarded to server, scopes parameter in browser and client
credentials OAuth2 flows with openid deduplication.

Deployment: oidc_scopes_claim wired through DeployOptions, docker.rs,
Helm, bootstrap scripts, and cluster entrypoint.

Keycloak: realm config updated with built-in OIDC scopes and 9
OpenShell client scopes as optional on openshell-cli and openshell:all
as default on openshell-ci.

* fix(auth): address branch review findings

Add GetInferenceBundle to sandbox-secret methods so sandbox inference
route refresh works under OIDC. Make GetSandboxConfig dual-auth so CLI
users can read sandbox settings with Bearer tokens.

Preserve OIDC gateway metadata on restart — a bare gateway start
without --oidc-* flags no longer erases the stored OIDC registration.

Document CI client ID requirement (openshell-ci vs openshell-cli) in
the testing guide. Add security note about auth-only mode blast radius
for GitHub Actions.

* fix(auth): complete review findings for OIDC auth boundary

Move OpenShell/GetSandboxConfig from sandbox-secret-only to dual-auth
so CLI users can read sandbox settings with Bearer tokens while sandbox
supervisors continue using the shared secret.

Add sandbox secret interceptor to the inference bundle fetch path so
GetInferenceBundle works under OIDC-enabled gateways. Extract shared
interceptor constructor to avoid duplication.

Add GetSandboxConfig to the config:read scope map so scope enforcement
applies consistently when scopes are enabled.

Refactor OIDC metadata preservation into apply_oidc_gateway_metadata()
with explicit resume semantics — only preserve existing OIDC metadata
on real resume paths, not on fresh deployments.

Update architecture docs and testing guide to reflect the corrected
method classifications and add new test coverage for interceptor
injection, scope requirements, metadata preservation, and dual-auth
classification.

* refactor(auth): use oauth2 crate for CLI OIDC flows

Replace hand-written PKCE generation, authorization URL construction,
token exchange, client credentials, and token refresh with the oauth2
crate's typed API.

Eliminates sha2, hex, and getrandom dependencies from the CLI. The
custom urlencoded() helper and manual form POST logic are replaced by
BasicClient methods with proper type-state safety.

Discovery and the callback server remain custom since the oauth2 crate
does not provide OIDC discovery or a localhost redirect listener.

* refactor(auth): move server auth modules into auth/ directory

Group oidc.rs, authz.rs, identity.rs, and the auth HTTP endpoints
under src/auth/ module directory. No behavioral changes.

  auth/mod.rs      — module root, re-exports HTTP router
  auth/oidc.rs     — JWT validation, JWKS caching, method classification
  auth/authz.rs    — role and scope authorization policy
  auth/identity.rs — provider-agnostic Identity type
  auth/http.rs     — /auth/connect and /auth/oidc-config endpoints

* fix(auth): use RequestBody auth type for client credentials flow

The oauth2 crate defaults to BasicAuth (HTTP Basic header) but Keycloak
and most OIDC providers expect client_secret_post (credentials in the
request body). Set AuthType::RequestBody explicitly to match the
pre-refactor behavior.

Also re-export Identity, IdentityProvider, and JwksCache from the auth
module so ServerState's public API remains nameable by external consumers.

* fix(auth): forward OPENSHELL_OIDC_SCOPES through cluster bootstrap

Pass --oidc-scopes to gateway start so the metadata includes requested
scopes after cluster bootstrap. Without this, users had to manually
edit metadata.json to set scopes for gateway login.

Usage: OPENSHELL_OIDC_SCOPES="openshell:all" mise run cluster

* test(auth): add OIDC e2e tests for RBAC, scopes, and client credentials

Add 10 end-to-end tests covering OIDC authentication against a live
K3s cluster with Keycloak:

RBAC (5 tests): admin can create providers, user cannot, user can list
sandboxes, unauthenticated requests rejected, health probe works
without auth.

Scopes (4 tests): sandbox-scoped token can list sandboxes but not
providers, openshell:all grants full access, no-scopes token denied.

Client credentials (1 test): CI token via client_credentials grant.

Tests are opt-in via OPENSHELL_E2E_OIDC=1 and OPENSHELL_E2E_OIDC_SCOPES=1
env vars. They derive the Keycloak URL from gateway metadata to match
the server's configured issuer.

Run with:

  OPENSHELL_E2E_OIDC=1 OPENSHELL_E2E_OIDC_SCOPES=1 \
  PYTHONPATH=python uv run pytest e2e/python/oidc/ -v

* fix(docs): fix markdown lint errors in OIDC architecture docs

Add blank lines before lists and fenced code blocks to satisfy
markdownlint MD031 and MD032 rules.

* ci(docker): use prebuilt Rust binaries by default

Flip Docker image builds to consume staged native Rust artifacts, remove in-Docker Rust build stages, and publish per-arch images with a manifest merge.

Add local staging support for prebuilt gateway and sandbox binaries so development image builds continue to work without CI artifacts.

Adam Miller d44d8a1e27 feat: Openshell driver podman (#904)
* feat(podman): add Podman compute driver for rootless sandbox management

Adds openshell-driver-podman, a new compute driver that manages OpenShell
sandboxes as rootless Podman containers via the Podman REST API over a
Unix socket. Enables local workstation sandboxes without Kubernetes.

Driver features:
- Bridge networking with ephemeral host-port mapping for rootless SSH reachability
- Named volumes for workspace storage, Podman native health checks, GPU via CDI
- Supervisor binary sideloaded via image volume mount (BYOC-compatible)
- SSH handshake secret injected via Podman secrets API (not plaintext env)
- Typed ContainerSpec structs, input validation, and path-traversal guards
- Cgroups v2 required; fails fast on v1 hosts
- Bounded event stream buffer; watch stream reconnection handled by server watch_loop
- Graceful shutdown and standalone driver binary with gRPC bridge

Rootless-specific fixes:
- Skip drop_privileges when user namespace lacks SETUID/SETGID/DAC_READ_SEARCH caps
- Add /run/netns tmpfs mount for ip netns in rootless containers
- Use secret_env map (not secrets array) for env-var injection in libpod API
- Resolve SSH endpoint to 127.0.0.1:<host_port> instead of unreachable bridge IP

Server/sandbox hardening:
- Split loopback and link-local SSRF gates; Podman/VM drivers allow loopback
- Close SSRF bypass in SSH tunnel Host path by resolving DNS before connecting
- Prevent OPENSHELL_* env var override by user-supplied spec environment maps
- Disable SQLite pool idle_timeout/max_lifetime for in-memory databases
- Emit deleted_event on 404-during-inspect instead of regressing sandbox phase
- Key delete cleanup by stable sandbox_id to survive container label drift

CLI fixes:
- Restore --name as a named flag on sandbox create (not positional)
- Fix exec command arg parsing to not consume sandboxed-command flags
- Propagate SSH verbosity via OPENSHELL_SSH_LOG_LEVEL

Build tooling:
- Add tasks/scripts/container-engine.sh: auto-detects Podman or Docker, exposes
  unified ce_* helpers; all build/cluster/VM scripts updated to use it
- Add docker:build:supervisor mise task for standalone supervisor image
- Add openshell-driver-podman to Dockerfile.images pre-fetch/build stages
- Add e2e/rust/e2e-podman.sh and e2e:podman mise task for full lifecycle testing

* fix(driver-podman): derive grpc endpoint from server bind port

When a user starts the gateway on a non-default port (e.g. --port 8081),
sandbox containers were receiving OPENSHELL_ENDPOINT pointing at the
default port 8080. The driver's auto-detection fallback read
OPENSHELL_BIND_ADDRESS from the environment, which was stale or unset,
and fell back to DEFAULT_SERVER_PORT.

Add gateway_port to PodmanComputeConfig and thread config.bind_address.port()
from the server into the driver so the fallback uses the actual listening
port. Remove the OPENSHELL_BIND_ADDRESS env var read and the
extract_port_from_bind_address helper which are no longer needed.

Add --gateway-port / OPENSHELL_GATEWAY_PORT to the standalone driver
binary for parity when the driver is run outside the embedded server path.

* fix(driver-podman): address PR feedback on env test safety and cluster DNS docs

Replace hand-rolled unsafe TempEnvVar RAII guard with temp_env::with_vars
and a static ENV_LOCK mutex, fixing a data race in parallel test execution.
The prior safety comment incorrectly claimed Cargo runs tests single-threaded.

Update debug-openshell-cluster skill to accurately document the DNS proxy
strategy (setup_dns_proxy + public DNS fallback) and clarify the separation
between cluster DNS and sandbox agent DNS enforcement.

* fix(e2e): resolve CI failures in auth timeout, test harness, and formatting

- Short-circuit browser_auth_flow when OPENSHELL_NO_BROWSER=1 instead
  of waiting the full 120s AUTH_TIMEOUT for a callback that never arrives
- Add timeout to SandboxGuard::create() and create_with_upload() to
  prevent indefinite hangs (matches create_keep() which already had one)
- Add missing '--' separator in no_proxy test before command args
- Add #![cfg(feature = "e2e")] gate to sandbox_lifecycle.rs
- Run cargo fmt on openshell-driver-podman
- Refine cluster DNS docs for Podman in debug-openshell-cluster skill

* refactor(server): remove allows_loopback_endpoints from ComputeRuntime

SSRF protection is now handled at the network and proxy layers
(openshell-core net.rs, openshell-sandbox proxy.rs) rather than
requiring per-driver flags on ComputeRuntime. Update architecture
docs to reflect supervisor relay SSH transport and add rootless
networking deep-dive.
