From d2393c431a6a6b65c2d3aa210976ace87c8a265b Mon Sep 17 00:00:00 2001 From: Miguel Angel Ajo Pelayo Date: Fri, 19 Jun 2026 10:49:15 +0200 Subject: [PATCH 01/10] fix: add logging to authentication errors in controller and router Log authentication failures across the controller service (Listen, GetLease, RequestLease, ReleaseLease, ListLeases, Register, Unregister, Status, Dial), the Auth helpers (AuthClient, AuthExporter) which cover all ClientService call sites, the router service, and the Python exporter's PassphraseInterceptor. The peer IP address is extracted from the gRPC context and included in every auth log entry. For ClientService paths the peer is attached via peerAddr(); for ControllerService unary handlers logContext() is called at the start of each method so the peer propagates into all subsequent log entries including the auth failure. Log level: Info (not Error) is used intentionally, following the convention established by kube-apiserver. Authentication rejections are expected adversarial events, not controller bugs. Using Error would conflate "something is broken in the controller" with "a caller sent a bad token", muddying alerts. The controller-runtime/logr interface has no native Warn level (the backend is zapr, which maps logr.Info -> zap INFO and logr.Error -> zap ERROR with no WARN in between), so Info at the default V=0 verbosity is the correct choice for security-relevant but operationally normal events. Also fix the router JWT validation gRPC status code from codes.InvalidArgument to codes.Unauthenticated, which is the semantically correct code for a failed authentication.

Remove duplicate auth-failure log lines from controller_service.go; auth helpers (AuthClient/AuthExporter) already log at the single ownership point, so per-RPC re-logging was noisy and redundant. - Remove redundant ctx = logContext(ctx) calls from GetLease, RequestLease, ReleaseLease, ListLeases, and Register; the gRPC unary interceptor already enriches every unary context, and the stream interceptor (wrappedStream) does the same for streaming RPCs. - Unify peer format: logContext now strips the port via net.SplitHostPort, matching the format used by peerAddr in auth.go, so the "peer" key is consistently IP-only across all log sites. - router_service.go Stream: call logContext before authenticate so the peer IP is available in the router auth-failure log entry. -

Self-contained and excluded from the compat suites, which run against old controller images. - Direct-listener passphrase rejection specs now also assert the exporter-side warning log (with the RPC method name and without the presented passphrase value). - utils: add SetYAMLField, ControllerLogsSince and ProcessTracker.StartExporterWithConfig helpers.
