Describe your changes

The provider form accepts anything and finds out later. A typo in the upstream, a key pasted a character short, an AWS access key in a field that wants a Bedrock API key — all save cleanly, then surface minutes later as a failed request or an empty model picker, with nothing pointing back at the record that caused it.

CreateProvider now spends the credential once against the vendor's own model listing, and UpdateProvider does the same when the upstream, the key or the catalog provider changed — only then, so renames, model rows and price edits neither wait on a vendor nor fail because one is having a bad day. The catalog entry counts because it decides which vendor is asked and under which auth header: moving a record between them offers an unchanged credential somewhere it has never been accepted. Both run before the store write, so a rejected rotation leaves the working key exactly where it was.

The check reuses the discovery Fetch rather than a lighter status probe. It exercises the path the model picker will take, so a URL answering 200 with a login page fails here instead of passing a status check and producing an empty picker later.

Failures that mean "we cannot ask" are not failures. A gateway with no listing endpoint, a Bedrock record behind a proxy where no control-plane host can be derived, and a self-hosted endpoint on a private network that the proxy reaches through the tunnel but management cannot — all still save. None is evidence the record is wrong, and refusing them would make this a lockout. That covers 11 of the 15 catalog entries; descriptors for the rest are separate work.

Every other failure blocks, vendor outages included. 5xx, 429 and timeouts fail the same as a rejected credential: the record went unverified either way, and saving what we could not check is the thing this prevents.

The message an operator sees carries no status code and never echoes their URL — WriteError lowercases it and paths are case-sensitive, so an echoed URL would come back altered and describe something they did not type. The vendor's status is logged instead.

Trigger message
401, 403 the provider rejected the credential
404, 405 the upstream url did not answer a model listing
200, unparseable the upstream url answered, but not with a model listing
dns, refused, tls, timeout the upstream url could not be reached: <which one>
5xx, 429 the provider returned an error

Returns 422 rather than 400: status.InvalidArgument maps to 422 in WriteError, and every existing provider validation error already goes out that way.

Two things the listing could not vouch for on its own.

A discovery request naming a saved record resolved its upstream from the stored row, so a URL retyped on the form could not be listed against without also rotating the credential — the one field the API never returns. The request now reads as a partial edit of the record it names, the same way PUT on a provider already does: an upstream in the body overrides the stored one, an omitted upstream keeps it. The credential and the catalog entry still come from the record only. This adds no reach a caller did not have — the same PUT runs the check against any upstream it likes, and no role grants providers Create without Update.

And Bedrock lists from the control plane while it infers on the runtime host, so a successful listing said nothing about the URL on the record. An upstream matching no catalog template left no region to derive, which skipped the check entirely: a record pointed at a host that does not exist saved clean. Entries declaring a listing host of their own now have their configured upstream resolved on its own account — one that will not resolve blocks, one resolving privately stays the unverifiable case it already was.

Checklist

  • Is it a bug fix
  • Is a typo/documentation fix
  • Is a feature enhancement
  • It is a refactor
  • Created tests that fail without the change (if possible)
  • I ran and tested this change locally — I did not rely on CI to find out whether it works
  • This PR has a single purpose (not a fix + refactor + feature in one)
  • This change is a trivial fix, OR it links an issue the NetBird team agreed on beforehand. Changes to the public API, gRPC protocols, functionality behavior, CLI / service flags, or new features always need that agreement first. See CONTRIBUTING.md.

On testing: build, unit tests and golangci-lint pass locally on every touched package. The Agent Network E2E workflow was dispatched against this branch (run 167, then 168 green end to end) and the live suite passed for all three vendors — OpenAI, Anthropic and Bedrock each refuse a corrupted key on their listing endpoint and accept the real one, which is the assumption the feature rests on and the one thing a unit test cannot establish.

Run 167 also found two things, both fixed in 6c7a6c3fb. A hostname that does not resolve failed inside the SSRF guard before any request was built, so it never became an UnreachableError and reached the operator as "could not be checked" rather than "could not be reached" — the commonest way an upstream is wrong. And newProvider in the e2e fixtures pointed a dummy key at the real api.openai.com, which the check correctly refuses; it wants a provider row to hang a policy off, so it moved to a private upstream that is left unchecked either way.

A third came out of the same run and is worth naming separately: this sandbox egresses through a proxy on loopback, so the dial-time guard refused the proxy as a private host, which classified as "cannot be checked" and let every save through. A proxied deployment would have installed this feature and had it quietly do nothing. bfc96ec9b fixes it and a test pins it.

Host resolution now shares one deadline with the request it precedes, rather than each lookup taking its own eight seconds from a background context — so fetchTimeout bounds the whole call and a caller that gives up is not left waiting on a resolver.

The remaining failures in run 167 are the pre-existing GeoLite2 startup stall (initGeoLookup downloads with a 2-minute timeout inside a 90s readiness wait; main's scheduled run fails the same way) and a guardrail TTL assertion that also failed on the previous run.

Summary by CodeRabbit

  • New Features

    • Provider credentials are now validated against upstream model listings when creating or updating configurations.
    • Invalid credentials, unreachable services, outages, and timeouts return clear validation errors.
    • Configurations with unavailable or private discovery endpoints can be saved as unverified.
    • Failed credential updates no longer overwrite the previously working key.
    • Changes to provider, catalog, or upstream settings trigger appropriate revalidation.
  • Documentation

    • Clarified how stored and form-provided credentials and upstream URLs are used during model discovery.

The provider form accepted anything and found out later. A typo in the
upstream, a key pasted a character short, an AWS access key in a field that
wants a Bedrock API key — all saved cleanly, then surfaced minutes later as a
failed request or an empty model picker, with nothing pointing back at the
record that caused it.

CreateProvider now spends the credential once against the vendor's own model
listing, and UpdateProvider does the same when the upstream or the key
changed — only then, so renames, model rows and price edits neither wait on a
vendor nor fail because one is having a bad day. Both run before the store
write, so a rejected rotation leaves the working key exactly where it was.

The check reuses the discovery Fetch rather than a lighter status probe. It
exercises the path the model picker will take, so a URL answering 200 with a
login page fails here instead of passing a status check and producing an empty
picker later.

Failures that mean "we cannot ask" are not failures: a gateway with no listing
endpoint, a Bedrock record behind a proxy where no control-plane host can be
derived, and a self-hosted endpoint on a private network that the proxy
reaches through the tunnel but management cannot. None of those are evidence
the record is wrong, and refusing them would make this a lockout.

Discovery failures are typed for it. The message an operator sees carries no
status code and never echoes their URL — WriteError lowercases it, and paths
are case-sensitive, so an echoed URL would come back altered and describe
something they did not type. The vendor's status is logged instead.
The OpenAPI change is the 422 both provider routes can now answer, plus what
decides it: the create path checks the pair before storing, the update path
checks only when the upstream or the key moved, and an update omitting the key
is checked against the stored one.

The live tests cover what a unit test structurally cannot. Mocked refusals
prove the classifier maps a status to a message; they cannot show that these
vendors refuse a bad key on their listing endpoint at all, which is the
assumption the feature rests on. The good-key case earns its place beside the
bad one — a check that refused everything would satisfy a test asserting only
the refusal.

The rotation case pins the state worth the most: after a rejected key, an edit
that reuses the stored one still passes. The API never returns a key, so that
is the only way to show the working credential is still there.
The SSRF guard resolves the host before any request is built, so a name that
does not resolve fails there rather than at the transport, and that error
reached the caller unclassified — an operator with a typo in the hostname was
told the provider could not be checked rather than that the url could not be
reached. It is the commonest way for an upstream to be wrong.

The live suite is what caught it: the unit tests construct the transport
errors directly and so never went through the guard.

The management fixture moves to a private upstream in the same change. It
wants a provider row to hang a policy off, not a working vendor, and it was
pointing a dummy key at the real api.openai.com — which the credential check
now correctly refuses. A private address is left unchecked whether or not the
run has vendor keys, and covers that path while it is there.

📝 Walkthrough

Walkthrough

Provider creation and updates now validate changed credentials through model discovery before persistence. Discovery failures use typed classifications. Unit, bootstrap, API contract, and live end-to-end tests cover the new behavior.

Changes

Provider credential validation

Layer / File(s) Summary
Discovery failure contracts

Environment-gated tests validate OpenAI, Anthropic, and AWS Bedrock credentials, unreachable URLs, rejected rotations, and preservation of working keys. Provider fixtures use a private unreachable upstream.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to afffc

The change adds pre-save upstream and credential validation, but the current head can still permit cleartext runtime URLs, route stored credentials to caller-controlled hosts, and mishandle rejected saves or host failures. These issues could expose credentials or persist invalid provider state, so the PR is not merge-ready without fixes or explicit owner acceptance.

The dial-time guard reported every non-public address as ErrPrivateHost, which
the credential check reads as "this upstream cannot be reached from here, so
save it unchecked". checkPublicHost has already cleared the target by the time
anything is dialled, so an address refused at the socket is never the
operator's upstream — it is a rebinding attempt, or an HTTP proxy the
management server egresses through. A deployment behind such a proxy would
install this feature and have it silently do nothing on every provider.

It now reports an ordinary failure, which classifies as unreachable and blocks.
Only the resolve-stage check still means "cannot be checked", and that one
knows it is looking at the operator's own host.

This is also why the three fixtures below passed locally and failed in CI: a
sandbox that egresses through a loopback proxy skipped the check entirely,
while CI reached the real api.openai.com and had the dummy key refused. They
want a provider row rather than a working vendor, so they move to a private
address and no longer depend on where a hostname resolves or whether the runner
has egress.

Use the caller context for host resolution.

Fetch creates its timeout after discoveryURL, while checkPublicHost uses a separate context.Background() timeout. DNS validation can therefore consume 8 seconds before the HTTP request gets another 8 seconds, and caller cancellation cannot stop it. Pass ctx into host validation so fetchTimeout bounds the full operation.

Pressing "Load models from provider" against a key the vendor refuses answered
"internal server error". Every outcome on that path is the operator's own key
or upstream, so a 500 was wrong twice over: it told them the server broke, and
it named nothing they could act on.

The failures are already typed and already have sentences written for them —
the save-time check translates the same set. Discovery now runs them through
the same classifier, so the button reports a refused credential or an
unreachable url in the words the form uses elsewhere.

ErrNoDiscovery and ErrInvalidRequest pass through untouched. The handler maps
both already, and a provider with no listing endpoint is a fact about the
catalog entry rather than a failure — the caller falls back to the catalog's
own models instead of showing an error at all.

Classify non-checkable host errors on the discovery path.

Lines 66-68 return ErrNoDiscoveryHost and ErrPrivateHost unchanged because credentialCheckFailure returns an empty message for both. The documented handler passthrough covers only ErrNoDiscovery and ErrInvalidRequest. These host errors can therefore use the generic 500 path instead of returning the required 422 response.

Keep these errors non-blocking for provider saves. Map them to a safe InvalidArgument message in discoveryFailure. Add discovery-flow tests for both sentinels.

Editing a provider's upstream URL meant retyping its API key. The key is the
one field the API never returns, so there was nothing to retype from, and the
dashboard had to demand it because a provider_id request resolved the upstream
from the stored row — listing the old endpoint while the form showed the new
one.

The request now reads as a partial edit of the record it names, the same way
PUT on a provider already does: an upstream in the body overrides the stored
one, an omitted upstream keeps it. The credential and the catalog entry still
come from the record only, so a caller cannot aim a stored key at a vendor of
their choosing.

Restrict URL overrides before sending the stored credential.

When recordID is set for a catalog entry without a fixed discovery host, Fetch derives the host from req.UpstreamURL, checks only that it resolves publicly, then attaches req.APIKey. A caller with Create permission can send a stored provider key to an attacker-controlled public host. Reject unapproved URL overrides or require explicit host authorization.

In `@management/internals/modules/agentnetwork/manager.go` around lines 233 - 240,
Update Fetch and the UpstreamURL override handling around recordID so
caller-supplied URLs cannot receive record.APIKey unless their host is
explicitly authorized for the catalog entry. Reject unapproved overrides before
credential attachment, while preserving permitted fixed discovery hosts and
existing stored-URL fallback behavior.

Bedrock lists from the control plane and infers on the runtime host, so a
successful listing says nothing about the URL on the record. An upstream
matching no catalog template left no region to derive, which skipped the check
entirely: a record pointed at a host that does not exist saved clean, and every
request it later served went nowhere.

Entries that declare a listing host of their own now have their configured
upstream resolved on its own account. A host that will not resolve blocks the
save; one that resolves privately does not, since Bedrock behind a proxy is a
supported configuration and stays the unverifiable case it already was.

Reject cleartext runtime upstream URLs.

url.Parse accepts http:// URLs, and this function only checks Hostname(). For providers such as Bedrock, the HTTPS control-plane listing can succeed and allow an http:// runtime upstream to be saved. Reject every scheme except HTTPS before resolving the host. Add a regression test for an http:// UpstreamURL.

Proposed fix
 parsed, err := url.Parse(strings.TrimSpace(upstreamURL))
-if err != nil || parsed.Hostname() == "" {
+if err != nil || !strings.EqualFold(parsed.Scheme, "https") || parsed.Hostname() == "" {
   return fmt.Errorf("%w: provider upstream %q is not a usable URL", ErrInvalidRequest, upstreamURL)
 }

As per coding guidelines, never accept http:// where https:// is expected.

Two gaps a review surfaced.

Moving a record from one catalog provider to another changed neither field the
check looked at, so an unchanged credential started being offered to a
different vendor, under a different auth header, with nothing asking whether it
was accepted there.

And each host lookup built its own eight-second budget from a background
context, so a slow resolver could spend one before the request spent another,
and a caller that gave up was still waiting. Bedrock made that three: it now
checks its runtime host as well. One deadline is taken at the top of Fetch and
carried through both lookups and the request.

The create description also had the exemption backwards, reading as though an
upstream the check cannot reach is stored unverified. Unreachable blocks; only
what cannot be checked at all is exempt.
The generated file carries the schema descriptions as doc comments, so editing
them leaves it behind and the release job's diff check fails. Comments only —
no field or type moved.

Two gaps a review found in the live suite.

The rotation test finished by renaming the provider and expecting that to
succeed. A rename touches none of the fields the check looks at, so it is
stored without asking the vendor anything — it would have passed just as well
against a key the rotation had already replaced. It now moves the upstream by a
trailing slash, which reaches the same host but differs as a string, so the
check runs and the stored key is what has to satisfy it.

And the refused-url test only asserted the error. An error is not the same fact
as an absent record, so it now lists the providers and looks for the one that
must not be there — which the refused-key test beside it already did.

The discovery upstream override is logged. It sends the stored credential to a
host the caller named, which the same permission set can already do by pointing
the record there and letting the write check it — but that leaves an activity
event behind, and this would otherwise leave nothing.
