From 4e7df6206eb0d97b6982d4ca5b904532d5248103 Mon Sep 17 00:00:00 2001 From: didericis Date: Fri, 17 Jul 2026 18:02:59 -0400 Subject: [PATCH] refactor(gateway): remove the single-tenant data-plane paths (audit #400 finding 3) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All three backends (docker, firecracker, macos-container) now launch through the consolidated orchestrator, and every production gateway sets BOT_BOTTLE_ORCHESTRATOR_URL — so the legacy single-tenant (`resolver is None`) branches in the shared gateway's data plane were unreachable dead code, a second security-relevant path to keep correct in parallel with the live one. Make the orchestrator resolver mandatory and delete the single-tenant paths from the three data-plane modules. egress_addon.py: drop the static routes file entirely — EGRESS_ROUTES, _reload, the SIGHUP handler, self.config, and the SUPERVISE_BOTTLE_SLUG env slug. The per-request /resolve is the only policy source; __init__ fail-closes if BOT_BOTTLE_ORCHESTRATOR_URL is unset. Introspection (`_egress.local/allowlist`) now reports the calling bottle's *resolved* routes. The block/redact log gates and _req_ctx redaction now read the per-flow config/env from the request-time stash, so they use each bottle's log level and token set (they silently used the empty static config before). Nothing sends `docker kill --signal HUP` to the gateway in the consolidated model (the egress applicators fail closed), so removing the SIGHUP reload is safe. git_http_backend.py: resolver mandatory; no flat-root fallback. main() refuses to start without an orchestrator URL; a request whose source resolves to no bottle 404s. supervise_server.py: resolver mandatory; every proposal is attributed to the source-IP-resolved bottle. Remove handle_list_egress_routes (the proxy-fetch introspection that only worked when the proxy carried one bottle's identity) — list-egress-routes is answered from the resolved policy. main() refuses to start without an orchestrator URL. Tests: a host-side fake resolver serves each test's Config through the real parse path (a small YAML-subset emitter round-trips route_to_yaml_dict); the response/websocket hooks stash it as request() would. Deletes the tests for the removed static-config, SIGHUP-reload, and single-tenant-passthrough paths; adds fail-closed-without-orchestrator coverage. Follow-up: gateway_init still forwards SIGHUP to the egress child (now dormant — no one sends it); the README still describes the docker backend's per-bottle topology. Both are outside the data-plane teardown.
