MED-1 (verification only): Fix 01's CRIT-1 router-gate sweep already wraps every read endpoint with rbacGate(reg.Checker, '<resource>.read', ...). Verified post-sweep that GET /api/v1/certificates, /profiles, /issuers, /targets, /agents, /audit all carry the corresponding *.read permission gate. MED-2: ListSessions now gates ?actor_id=<other> on auth.session.list.all via the new permissionChecker projection installed by WithPermissionChecker. cmd/server/main.go threads the existing authCheckerAdapter into the handler. When caller's actor_id != caller.ActorID AND the handler has a checker, an inline CheckPermission(..., 'auth.session.list.all', 'global', nil) call fires; on false → 403 with explanatory message; on repository error → 500. Defense-in-depth: the router-level rbacGate enforces auth.session.list as the floor; the .list.all re-check is the privilege-elevation guard for cross-actor queries that the rbacGate can't express (it can't see the query parameter). MED-3: ship DELETE /api/v1/auth/sessions?except=current — the 'sign out all other sessions' flow. Gated by auth.session.revoke; the handler reads the caller's current session ID from session.SessionFromContext(ctx) (cookie-mode); empty for Bearer-mode callers (in which case ALL the actor's sessions revoke, matching 'log me out everywhere' semantic for API-key users). New repository method SessionRepository.RevokeAllExceptForActor: UPDATE sessions SET revoked_at = NOW() WHERE actor_id = AND actor_type = AND tenant_id = AND revoked_at IS NULL AND id != returning rowcount. Added to the interface in internal/repository/session.go, wired into postgres impl, and added to all SessionRepo test stubs (handler stubSessionRepo, service-test stubSessionRepo, benchmark slowSessionRepo). The session.SessionRepo internal interface also gains the method so the bench_test.go forwarder compiles. Audit row records the count for compliance evidence (one summary row per invocation per the existing audit policy). OpenAPI parity exception added for the new route — the unbounded-DELETE-with-query-flag shape doesn't fit standard REST CRUD operations cleanly; matches the documented-inline pattern set by the streaming audit-export endpoint. GUI button (SessionsPage 'Sign out all other sessions') deferred to Phase D.

shankar0123	1697845493	fix(auth): wire RevokeAllForActor + RotateCSRFToken to mutation paths ... Closes HIGH-1 + HIGH-2 of the 2026-05-10 audit. HIGH-1: breakglass.Service.SetPassword and RemoveCredential now call sessions.RevokeAllForActor(targetActorID, "User") best-effort after the mutation completes. A phished-then-rotated password no longer leaves the attacker's session alive (CWE-613). Failure to revoke is audited with outcome=session_revoke_failed and logged at WARN level but does NOT roll back the credential change (the operator rotated for a reason; forcing rollback opens a worse window). - breakglass.SessionMinter interface extended with RevokeAllForActor. - cmd/server/main.go::breakglassSessionMinterAdapter gains the bridge to session.Service.RevokeAllForActor. - stubSessions in service_test.go tracks revokeAllIDs / revokeAllTypes / revokeAllErr. - Three regression tests: - TestService_SetPassword_RevokesExistingSessions - TestService_RemoveCredential_RevokesExistingSessions - TestService_SetPassword_RevokeFailureDoesNotRollback HIGH-2: New session.Service.RotateCSRFTokenForActor(ctx, actorID, actorType) int method walks ListByActor and rotates the CSRF token on every active (non-revoked, non-expired) row. Returns count rotated; per-row failures log WARN + skip, never errors to caller. New handler.CSRFRotator interface + AuthHandler.WithCSRFRotator(r) setter; AssignRoleToKey and RevokeRoleFromKey invoke it post-success as defense-in-depth (a CSRF token leaked while the actor held a lower- priv role no longer rides through to the elevated role). - SessionRepo interface gains ListByActor (already implemented on the postgres SessionRepository; stubs in service_test.go + bench_test.go updated to match). - cmd/server/main.go calls .WithCSRFRotator(sessionService) on the AuthHandler. - Two regression tests: - TestRotateCSRFTokenForActor_RotatesAllActiveRows (asserts revoked / expired / other-actor rows are skipped) - TestRotateCSRFTokenForActor_NoSessionsReturnsZero Verification gate green: gofmt clean, go vet clean, go test -short -count=1 ./internal/auth/breakglass/ ./internal/auth/session/ ./internal/api/handler/ ./internal/api/router/ ./cmd/server/ ./internal/domain/auth/ — all pass. CRIT-1..CRIT-5 + HIGH-1 + HIGH-2 of the 2026-05-10 audit now closed on this branch. Spec at cowork/auth-bundles-fixes-2026-05-10/06-high-1-2-revoke-and-rotate.md.

shankar0123	9b6294e83d	auth-bundle-2 Phase 14: session + OIDC validation benchmarks (steady-state + cold paths) + auth-benchmarks.md operator doc + Makefile targets ... Closes Phase 14 of cowork/auth-bundle-2-prompt.md. Ships four benchmarks producing four numbers + the operator-doc table; three default-tag benchmarks runnable on every CI runner, the fourth (cold-cache OIDC) runnable on operator-side Docker hosts via the new make target. Files ===== internal/auth/session/bench_test.go (NEW): * BenchmarkSession_SteadyState (target p99 < 1ms; measured 5µs). Warm in-memory repo + warm session row. Pure CPU: parseCookie + HMAC verify + map lookup + sentinel checks. * BenchmarkSession_ColdProcess (target p99 < 10ms; measured 7.1ms). Same pipeline but with a configurable per-call delay simulating a 1ms Postgres RTT on each repo call. Two repo calls per Validate (signing-key fetch + session-row fetch) = 2ms minimum; Go time.Sleep granularity adds ~1-2ms jitter. Documented why testcontainers Postgres isn't viable inside b.N: 30+ second container boot incompatible with per-iteration timing. * slowSessionRepo + slowKeyRepo wrappers add the per-call delay via time.Sleep; they delegate to the existing in-memory stubs. * reportPercentiles helper sorts + reports p50/p95/p99/max via b.ReportMetric (Go testing.B doesn't surface percentiles natively). internal/auth/oidc/bench_test.go (NEW): * BenchmarkOIDC_SteadyState (target p99 < 5ms; measured 1.5ms). Drives full HandleCallback against an in-process mockIdP (httptest.Server localhost loopback). Pre-warmed JWKS cache via RefreshKeys at setup. Pipeline: pre-login consume + state compare + token exchange (localhost ~50-200µs) + go-oidc Verify (RSA-2048 sig verify + alg pin) + service-layer iss/ aud/azp/at_hash/exp/iat/nonce re-checks + group-claim resolution + group→role mapping + user upsert + session mint. * The localhost-loopback /token call adds ~100-500µs of TCP overhead vs pure crypto; the prompt's "no network calls" steady-state framing accommodates this since the localhost loopback is the closest practical proxy for a same-region IdP /token call (which adds 5-15ms in production). internal/auth/oidc/bench_keycloak_test.go (NEW, //go:build integration): * BenchmarkOIDC_ColdCache (target p99 < 200ms; operator-runs). Drives RefreshKeys against a live Keycloak container from the Phase 10 testfixtures harness. Each iteration evicts the in-process cache + re-fetches discovery + re-fetches JWKS over real HTTP + re-runs the IdP-downgrade-attack defense. * Network-bounded: the cold path is dominated by HTTPS RTT to the IdP discovery endpoint, NOT crypto. The 200ms cap accommodates a geographically-distant IdP (~150ms RTT) plus the in-process JWKS fetch + downgrade-defense logic (~5ms locally). * Reuses the sharedKeycloak fixture from integration_keycloak_test.go (Phase 10) so the benchmark doesn't pay the 60-90s container boot cost separately. Skips with a clear message if invoked without the integration test setup. * Reports p50/p95/p99/max in MILLISECONDS (vs the microsecond-granularity steady-state benchmarks) since the cold path is two orders of magnitude slower. internal/auth/oidc/service_test.go (MODIFIED): * Refactored newMockIdP(t *testing.T) to delegate to a new newMockIdPWithTB(t testing.TB) sibling. Standard Go pattern for sharing test fixtures between *testing.T and *testing.B. No behavior change for existing service_test.go tests; the benchmark file in bench_test.go calls newMockIdPWithTB(b) to get the same fixture. docs/operator/auth-benchmarks.md (NEW): * Result table with all four benchmarks + targets + measured numbers + status markers. Four-row matrix for the default-tag benchmarks; the fourth row (cold-cache) is operator-recorded with an empty cell waiting for the first Docker-equipped run. * Hardware floor section pinning the 4 vCPU / 8 GiB RAM / Postgres 16 / Go 1.25 baseline. GitHub-hosted Ubuntu runners satisfy this; operators on weaker hardware re-record. * "What each benchmark covers (and what it doesn't)" section per benchmark, distinguishing the warm steady-state pipeline from the cold path's network-bounded budget. * "Cold-cache OIDC: how to run" subsection documenting the make target + the test+benchmark coupling needed to populate sharedKeycloak. Operator-recorded baseline table seeded empty for first runs. * "Why the cold path is bounded by network latency, not crypto" section explaining the budget breakdown: - TCP handshake (1 RTT) - TLS 1.3 handshake (1-2 RTTs) - 2 HTTPS GETs (discovery + JWKS, 1 RTT each) - In-process crypto on the certctl side (~5-10ms total) So the 200ms cap is operator-checkable: real measurement > 200ms means the IdP is slow OR network congestion OR DNS issues — the diagnosis is upstream of certctl. Real measurement < 200ms means the IdP is on a fast same-region link. * Methodology section pinning the per-iteration timing capture + sort + percentile-extract approach. * Pre-merge audit section for the Phase 14 exit gate: four benchmarks ran, four numbers recorded, steady-state targets met, cold path is operator-runnable + measurably-bounded. Makefile (MODIFIED): * Added `make benchmark-auth` (default-tag, runs three of four benchmarks at 2000 samples each). * Added `make benchmark-auth-coldcache` (integration-tagged, runs OIDC cold-cache against live Keycloak; requires Docker). * Both targets carry explanatory comment blocks. docs/README.md (MODIFIED): * Added the auth-benchmarks.md doc to the Operator nav table alongside performance-baselines.md. Measured baselines at Phase 14 close (linux/arm64, 4 vCPU) ========================================================== BenchmarkSession_SteadyState p99 = 5µs (target < 1ms) ✓ 200× under BenchmarkSession_ColdProcess p99 = 7.1ms (target < 10ms) ✓ BenchmarkOIDC_SteadyState p99 = 1.5ms (target < 5ms) ✓ 3× under BenchmarkOIDC_ColdCache operator-runs (Docker required) Verification ============ * gofmt -l on three new bench files: clean. * go vet ./internal/auth/session/... ./internal/auth/oidc/...: clean (default tag). * go vet -tags integration ./internal/auth/oidc/...: clean (integration tag covers the bench_keycloak_test.go file). * go test -short -count=1 across all 5 OIDC + session packages: green; the bench_*_test.go files compile but don't run under -short (testing.Short() guards + benchmarks are not selected by -run pattern). * All three runnable benchmarks executed and produce the numbers above; recorded in auth-benchmarks.md.	2026-05-10 16:51:28 +00:00
