📝 WalkthroughWalkthroughAdded a Go admin token issuer proxy with Vault-backed token signing, API Keys metadata caching and readiness handling, HTTP endpoints, Bazel and OCI packaging, tests, documentation, and release integration. Updated BSD license detection and dependency classifications. ChangesAdmin token issuer proxy
Dependency license classification
Release and catalog maintenance
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to High merge risk remains because the service can mint administrative credentials for any caller admitted by surrounding network controls, while also accepting plaintext Vault endpoints and incomplete metadata that can produce invalid authorization values. These security and correctness issues should be fixed or explicitly accepted before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)
✅ Passed checks (3 passed)
Full details: Linked Issues checkExplanation The implementation satisfies issue Full details: Out of Scope Changes checkExplanation Most changes support the stated migration and cold-start objectives. However, changing initial version settings for unrelated compute-plane, self-managed, observability, and NVCA release subprojects is not directly related to issue Full details: Docstring CoverageExplanation Docstring coverage is 25.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 40 functions across 24 files. (5 skipped: 5 unsupported.)

Inline comments:
In
`@src/control-plane-services/admin-token-issuer-proxy/cmd/admin-issuer-proxy/image_entrypoint_mode_test.sh`:
- Around line 15-21: Update the candidate-processing loop to capture each
successful tar listing once, then run the regular-expression match against that
captured output instead of piping tar directly into grep under pipefail.
Preserve the existing archive-validation check and continue behavior, while
ensuring a matching usr/bin/admin-issuer-proxy entry is accepted reliably.
In
`@src/control-plane-services/admin-token-issuer-proxy/cmd/admin-issuer-proxy/main.go`:
- Line 78: Update main around the run invocation to create the root context with
signal.NotifyContext, listening for SIGTERM (and the existing termination signal
set), and defer the returned stop function. Pass this signal-aware context to
run instead of context.Background() so runCtx.Done() triggers the existing
graceful shutdown path.
In
`@src/control-plane-services/admin-token-issuer-proxy/internal/handlers/handlers.go`:
- Around line 99-101: Update the Keys, Health, and Ready handlers to replace
free-form log.Printf calls with the established structured logger and required
request, function, cluster, and organization context fields. Add tracing around
each Vault call and record request-rate, error, and duration metrics for every
endpoint, preserving wrapped errors with %w where errors are propagated.
- Around line 157-164: Update the JWT claim handling in the relevant handler so
a DecodeJWTClaims error logs the failure and immediately returns HTTP 500
instead of constructing default JWTClaims. Remove the placeholder scopes
fallback and ensure no response containing the signed token is produced when
decoding fails; preserve normal metadata generation for successfully decoded
claims.
- Around line 98-110: Update the Keys handler to enforce caller authorization
before minting any admin-scoped JWT, using the established gateway authorization
mechanism or an equivalent in-process check; also ensure the plain HTTP listener
is restricted to workload-only access where applicable. Preserve the existing
method and service-readiness checks.
In
`@src/control-plane-services/admin-token-issuer-proxy/internal/platform/vault/client.go`:
- Line 48: Update the Vault client configuration around the Address field and
SetToken flow to prevent transmitting the Vault token over plain HTTP: require
an HTTPS VAULT_ADDR, or explicitly enforce an authenticated protected local
transport boundary before Logical().Write sends X-Vault-Token. Reject insecure
configurations before setting or using the token.
In `@src/control-plane-services/admin-token-issuer-proxy/README.md`:
- Line 154: Update the README note about the JWT aud claim to state that it is
parsed for RFC 7519 compatibility only, not used for token validation or
response fields; clarify that handlers.Keys decodes claims for created_at,
expires_at, scopes, and owner_id without reading aud, while response audience
fields come from cached service metadata.
In `@tools/collect-dependencies/common.go`:
- Line 220: Extend the BSD-3-Clause detection logic near the existing checks in
the license classifier to recognize the unlabelled “Neither my name … may be
used …” and “None of the names … may be used …” variants, preventing them from
falling through to BSD-2-Clause. Add regression cases in the relevant tests and
regenerate the dependency documentation.

Addressed the four review-body nits in 91d7203: Vault write errors now wrap the resolved signing path; service-cache tests use strings.Contains; deprecated net.Error.Temporary usage is removed; and metadata requests now carry the startup context so in-flight requests cancel during shutdown. Regression suites pass under Go, the race detector, vet, and Bazel. |

golangci-lint noctx linter net.Listen httptest.NewRequest http.NewRequest
💡 Result:
The noctx linter in golangci-lint is designed to detect function and method calls that should ideally use a context.Context but are being called without one [1][2]. Regarding the specific functions you mentioned: - net.Listen: Yes, noctx flags net.Listen. It requires using (*net.ListenConfig).Listen instead, which accepts a context.Context [3][4]. - net/http.NewRequest: Yes, noctx flags net/http.NewRequest. It recommends using net/http.NewRequestWithContext instead [3][5]. - net/http/httptest.NewRequest: Yes, noctx flags net/http/httptest.NewRequest. It recommends using net/http/httptest.NewRequestWithContext (or ensuring appropriate context usage) [3]. Over time, the noctx linter has expanded its scope significantly beyond the initial net/http requests to include various net package functions (like net.Dial, net.Listen) and even os/exec.Command [6][7][4]. If you encounter these issues in code where adding context is not immediately feasible or desired, you can use //nolint:noctx to suppress the warning or configure the linter in your .golangci.yml file to exclude specific paths or patterns [8][7].

github.com/hashicorp/vault/api v1.23.0 Logical WriteWithContext Write source context cancellation
💡 Result:
In version 1.23.0 of the HashiCorp Vault Go API, the WriteWithContext method and the underlying write helper function suffered from a context handling pattern that could lead to premature cancellation of the request context [1][2][3]. Specifically, the write function (which WriteWithContext calls) used c.c.withConfiguredTimeout(ctx) to create a derived context and a cancelFunc, which was then deferred to execute as soon as the write function returned [2]. This meant that if the response body was still being read or processed by the caller after write returned, the context bound to that response body would be cancelled [1][3]. While this was often masked for small responses that were fully buffered in memory, it frequently caused spurious "context canceled" errors for larger responses or streaming scenarios where the body was read after the function returned [1][3]. This defect was identified in issue #31986 and addressed in commit e4390e0 [1][3]. The fix involved removing the withConfiguredTimeout wrapping and the deferred cancelFunc from the raw write/patch paths, allowing the context passed by the caller to remain active for the duration of the response body reading [3]. Users of version 1.23.0 may experience this issue, and it is resolved in subsequent versions by delegating context management more directly to the underlying RawRequestWithContext without premature cancellation [3].

Propagate the request context to the Vault write.
handlers.Keys does not pass r.Context() to VaultSigner.SignToken. SignToken calls Logical().Write, which delegates to WriteWithContext(context.Background(), ...). A canceled HTTP request therefore cannot cancel the Vault request. Update the interface and callers to accept context.Context, then call WriteWithContext. Add a cancellation test.

Add telemetry for the metadata request path.
FetchContext performs a cross-service request but emits no structured log, OpenTelemetry span, or RED metric. Add the established telemetry with function context and bounded labels. Initialize counters before use.
As per path instructions, “Request-handling and cross-service paths should add OpenTelemetry spans with propagated W3C context and RED metrics with bounded labels and initialized counters.”

Reject service metadata with an empty ServiceID.
If services[0] is {}, FetchContext caches it and IsReady returns true. handlers.Keys can then return 200 with an empty IssuerServiceID and policy Aud. Reject the record before caching and add a test.

admin-token-issuer-proxysource into the public NVCF monorepo/healthzfor liveness and/readyzfor metadata readiness; token requests return 503 until initialization completesCloses #1229.
Why readiness, not a startup probe
The process is healthy while API Keys is starting; it is only not ready to issue tokens. A startup probe would hide that distinction and delay liveness coverage. The chart should therefore keep liveness on
/healthz, use/readyzfor readiness, and omit a startup probe.Compatibility
