GHSA-2v4p-qf9q-27wj is a panic in gRPC-Go's xDS routing interceptor: a request arriving with neither `:authority` nor `Host` indexes an empty slice, the per-RPC goroutine does not recover, and the process dies. High, and nine alerts, because nine go.mod files pin the same version -- eight directly, terraform indirectly. Nothing here was reachable. The interceptor is installed by `xds.NewGRPCServer`, which this repo never calls: the one production server is `grpc.NewServer(grpc.Creds(...))` in ingest/internal/grpcserver and the only other is a plain one in a searchclient test. That is also why security-scan has been green throughout -- govulncheck reports on reachability and found nothing on 1.83.1, while Dependabot reports on version ranges and found nine. Both were right. Taken anyway: it is a patch release, and the next advisory in this dependency may well land somewhere we do reach. `go mod tidy` carried the indirect requirements grpc 1.83.2 asks for -- x/net, x/text, x/sys and friends. No CI job builds or tests Go here, so all nine modules were built locally and api, ingest and enterprise tested with -count=1, since a cached pass would not have exercised the new version. The dependabot.yml is the other half. There was no config, so nothing opened a PR against any of this. Go majors stay out of the group, being import path changes rather than bumps.
hack
Local developer tooling that isn't part of any shipped component — scripts
you run against your own machine/dev stack, not code that ends up in a
container image (except dev-certs' output, which mounts into the
ingest container).
Not one of the top-level directories in the original monorepo scaffold —
added because dev-only mTLS cert generation didn't have a natural home in
/deploy (real deployment manifests), /transport, or any other existing
component. /hack is the conventional name for this in a lot of larger Go
monorepos (Kubernetes among them).
dev-certs/— generates a throwaway CA + server/client cert pair for local mTLS between the agent and ingest. See/docs/phase-0-runbook.mdfor when to run it.windows-fixture/— sends synthetic Windows Event Log-shaped records directly toingest, bypassing the real Windows agent. Tests whether the pipeline handles Windows-shaped data; doesn't test the realEvtSubscribe/ETW integration, which needs actual Windows. See/docs/phase-1-runbook.md.demo-simulator/— the public demo's synthetic world: a fictional fleet whose agents check in, report CPU/memory/disk, and ship realistically shaped logs for eight services. Backfills a window of history, then keeps generating in real time. Distinct frombenchmark-fixture/(volume, for the Phase 2 latency benchmark) andwindows-fixture/(correctness, for the Windows ingest path).check-web-routes.sh— assertsweb/nginx.conf's hand-maintained route allowlists still matchweb/src/routes.nginx.conf404s unknown paths, so it has to name the routes that have no prerendered file to match (dynamic ones, and any route withoutprerender = true). Drift here breaks production only — dev andnpm run previewnever readnginx.conf— so this runs in CI, likecheck-tenant-boundary.sh.demo-seed/— the rest of the demo deployment: its reset script, dashboards, alert rules, and the systemd unit that runsdemo-simulator.
