F-001 (P3): GenerateDERCRL scoped to issuer via composite index
- Add RevocationRepository.ListByIssuer leveraging migration 000012's
idx_certificate_revocations_issuer_serial composite index as a
prefix-scan target. Previously CAOperationsSvc.GenerateDERCRL called
ListAll() and filtered by IssuerID in Go — O(total revocations)
regardless of how many revocations belonged to the target issuer.
- Rewrite GenerateDERCRL to call ListByIssuer(ctx, issuerID) so PostgreSQL
drives a prefix scan of the composite index. Drops the in-memory filter.
- New regression test in ca_operations_test.go asserts the CRL hot path
invokes ListByIssuer exactly once and never ListAll, and that the
issuerID is threaded through correctly.
F-002 (P3): digest.go admin-auth endpoints no longer leak internal errors
- PreviewDigest (GET /api/v1/digest/preview) and SendDigest
(POST /api/v1/digest/send) previously wrote err.Error() into the HTTP
response body on 500s. Replace with slog.Error server-side logging plus
a generic "internal error" response body, matching the house pattern
in certificates.go and export.go.
F-003 (P4): three blocking time.Sleep sites now honor ctx cancellation
- internal/connector/issuer/acme/acme.go:672 (DNS-01 propagation wait)
now runs under a select{case <-ctx.Done(): CleanUp + return ctx.Err();
case <-time.After(d):} so graceful shutdown doesn't get stuck behind
the propagation delay.
- internal/connector/issuer/acme/acme.go:786 (dns-persist-01 propagation
wait) same pattern, returns ctx.Err() on cancel.
- cmd/agent/main.go:272 (polling backoff inside the heartbeat loop) now
wraps the sleep in select{case <-ctx.Done(): continue; case <-time.After(backoff):}
so the outer <-ctx.Done() case on the parent loop fires cleanly.
Verification: build, vet, and race-enabled short tests green across all
55+ packages. govulncheck reports zero vulnerabilities in the code path.
No migration needed — F-001 reuses the existing 000012 composite index.
No frontend changes.
RFC 5280 §5.2.3 defines certificate serial number uniqueness per issuing CA,
not globally. The prior unique index on `certificate_revocations.serial_number`
enforced a stricter invariant than the spec: with 12 issuer connectors (Local
CA, ACME, Vault, step-ca, OpenSSL, DigiCert, Sectigo, Google CAS, AWS ACM PCA,
Entrust, GlobalSign, EJBCA), two distinct certificates legitimately issued by
different CAs can share a serial number. Recording a revocation for the second
collision silently dropped via `ON CONFLICT DO NOTHING`, leaving the second
cert persistently absent from OCSP/CRL responses.
Changes:
- Migration 000012 drops `idx_certificate_revocations_serial` and creates
`idx_certificate_revocations_issuer_serial` UNIQUE ON (issuer_id,
serial_number). Adds a non-unique `idx_certificate_revocations_serial_lookup`
to preserve the serial-only fast path for OCSP/CRL probes that already know
the issuer scope.
- `CertificateRevocationRepository.Create` targets the new composite key in
`ON CONFLICT` — same-issuer idempotency preserved, cross-issuer collisions
now recorded as distinct rows.
- `GetBySerial(serial)` renamed `GetByIssuerAndSerial(issuerID, serial)` on
the interface and Postgres impl. All callers (OCSP responder, CRL
generator, short-lived-cert exemption check) already have `issuerID` in
scope because the protocol paths carry it (`/api/v1/ocsp/{issuer_id}/{serial}`,
`/api/v1/crl/{issuer_id}`).
- Repository integration test added: `TestRevocationRepository_CrossIssuerSerialCollision`
asserts that serial `CAFEBABE01` can be stored under two issuers
simultaneously, that lookups return the correct row per (issuer, serial),
and that same-issuer idempotency still works (re-inserting (issuer, serial)
does not error and does not duplicate).
- Existing tests and service/integration mocks updated for the rename.
Wire-format invariants preserved: CRL DER bytes, OCSP response bytes, and
AES-256-GCM config encryption are unaffected — this change touches only
revocation-record uniqueness scope.
CWE-664.
Implements core revocation infrastructure: POST /api/v1/certificates/{id}/revoke
with all 8 RFC 5280 reason codes, JSON-formatted CRL at GET /api/v1/crl, webhook
and email revocation notifications, best-effort issuer notification, and immutable
revocation audit trail. Includes 48 new tests across service, handler, integration,
and domain layers (600+ total). Fixes 3 pre-existing test bugs (team_test error
matching, agent_group delete status code, team handler per_page validation).
