00:00:00 2001 From: Esity Date: Sat, 28 Mar 2026 23:35:55 -0500 Subject: [PATCH 073/129] add optional SPIFFE workload identity support (closes #8) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - WorkloadApiClient: Unix-domain socket Workload API client for fetching X.509 and JWT SVIDs from a local SPIRE agent; falls back to self-signed certificate when SPIRE is unavailable so callers never receive nil - SvidRotation: background thread mirroring CertRotation pattern; checks every 60s and rotates when remaining TTL fraction falls below renewal_window (default 50%) - IdentityHelpers: sign_with_svid, verify_svid_signature, extract_spiffe_id_from_cert, trusted_cert?, svid_identity — all operate on X509Svid/JwtSvid structs via stdlib OpenSSL, no new gems - Spiffe module: parse_id, valid_id?, enabled?, socket_path, trust_domain, workload_id accessors; SpiffeId/X509Svid/JwtSvid structs; full error hierarchy (InvalidSpiffeIdError, WorkloadApiError, SvidError) - Wired into Legion::Crypt.start/shutdown behind security.spiffe.enabled: false feature flag; delegation methods: spiffe_svid, fetch_svid, fetch_jwt_svid on Legion::Crypt - Fix decode_varint return value (was returning start_pos instead of bytes_consumed, breaking protobuf field extraction) - Fix self_signed_fallback subject CN (plain string, not spiffe:// URI, to satisfy OpenSSL::X509::Name.parse on Ruby 3.4) - 82 new specs, 478 total, 0 failures --- CHANGELOG.md | 6 +++- .../crypt/spiffe/workload_api_client.rb | 33

errors caused by the un-initialized global `::Vault` singleton (closes #1) +- `WorkloadApiClient#decode_varint`: returns `[value, bytes_consumed]` correctly; previous implementation returned `[value, start_pos]` causing the protobuf field scanner to never advance past the first tag, breaking `extract_proto_field` for any non-empty input +- `WorkloadApiClient#self_signed_fallback`: Subject CN is now a plain string (`legion-fallback-svid`) instead of the full `spiffe://` URI, preventing `TypeError: no implicit conversion of nil into String` from `OpenSSL::X509::Name.parse` on Ruby 3.4 +- `spiffe_identity_helpers_spec.rb`: test cert helper uses plain CN for the same reason ### Added - Specs for `kv_client`/`logical_client` routing: 20 examples covering multi-cluster path (cluster

Cluster-secret Vault synchronization now uses the documented `push_cluster_secret` setting, stores the new secret before pushing it, aligns Vault read/write path and field names, and invalidates cached derived key material on rotation - External JWT/JWKS verification now fails closed on missing issuer or audience expectations, keeps reserved claims library-controlled, requires HTTPS JWKS transport, and avoids repeated fresh-cache re-fetches for unknown `kid` values +- Multi-cluster Vault auth and helper routing now update live LDAP client tokens, avoid treating cluster connectivity as global Vault connectivity, allow explicit cluster-targeted helper calls, refresh lease metadata on renewal, and schedule short-lived token renewals before expiry ### Changed -

routing now update live LDAP client tokens, avoid treating cluster connectivity as global Vault connectivity, allow explicit cluster-targeted helper calls, refresh lease metadata on renewal, and schedule short-lived token renewals before expiry - SPIFFE X.509 fetch now fails closed by default, uses an explicit `allow_x509_fallback` development switch for self-signed fallback SVIDs, tags returned SVIDs with their source, and sends a valid 9-byte HTTP/2 SETTINGS frame during Workload API connection setup - Ed25519 helper key persistence now uses the supported `Legion::Crypt` API with normalized KV paths, and tenant erasure verification no longer reports success when Vault access itself failed +- Background worker lifecycle is now serialized and cooperative: repeated `Legion::Crypt.start` calls no longer spawn duplicate workers, renewal/rotation threads no longer use `Thread#kill`, and timed-out joins keep their live thread references instead of dropping them ###

The old approach silently reused stale credentials after Vault lease rotation, causing Apollo and other DB-backed services to lose access to data without any error indication. Now calls Legion::Data::Connection.reconnect_with_fresh_creds (added in legion-data 1.6.26) which tears down the pool and rebuilds it from current Settings values. Falls back to legacy path for older legion-data versions with an explicit warning. Reconnect failures now log at :error level (was :warn) since a failed reconnect means services are unavailable.
