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.
windows-fixture
Sends synthetic Windows Event Log-shaped PushBatchRequests directly to
ingest's gRPC endpoint, bypassing the actual Windows agent entirely.
What this does and doesn't test
Tests: can the pipeline (ingest → ClickHouse → search → api → web)
correctly handle Windows-shaped data — the winevt.* attributes, the
record_id join between SQL and full-text search, Windows severity
levels mapping onto the right column values? This is exactly what's
automatable without a Windows host, and it's genuinely exercised: five
realistic, well-known Windows events (failed/successful logon, a service
state change, an application crash, an unexpected reboot) with real
EventIDs and providers.
Does not test: whether the real Windows agent's EvtSubscribe/ETW
integration actually works, whether Windows service registration
succeeds, whether ETW session creation/provider enabling works. Those are
fundamentally different questions — they need a real or virtualized
Windows host, and nothing here pretends otherwise. See
/docs/phase-1-runbook.md for exactly which is which.
Running
Requires the docker-compose stack up (ingest reachable, dev certs
generated):
cd hack/windows-fixture
go run . --count 5
sent 5 synthetic Windows-shaped records, ingest accepted 5
[SEVERITY_WARN] An account failed to log on. (event_id=4625 provider=Microsoft-Windows-Security-Auditing)
...
Then confirm both query paths see it:
curl -s -X POST http://localhost:8080/query -H 'Content-Type: application/json' \
-d '{"query": "SELECT host, severity, message, attributes['"'"'winevt.event_id'"'"'] AS event_id FROM logs WHERE host = '"'"'WIN-FIXTURE-01'"'"' ORDER BY timestamp DESC"}'
curl -s -X POST http://localhost:8080/query -H 'Content-Type: application/json' \
-d '{"query": "notepad"}'
Flags: --addr (default localhost:4317), --ca/--cert/--key
(default to ../dev-certs/out/{ca,client,client-key}.pem), --count
(default 5, cycles through the fixed event list if higher).
