Chris Lu c47eab1a5d admin: attach admin-signed Bearer token on filer IAM gRPC calls (#9498)
* admin: attach admin-signed Bearer token on filer IAM gRPC calls

PR #9442 added Bearer-JWT enforcement on the filer's IAM gRPC service
but didn't update its only production client, IamGrpcStore. The admin
UI Users/Groups pages went through that client and started failing in
4.24 with either Unimplemented (filer refuses to register the service
when jwt.filer_signing.key is empty) or Unauthenticated (the client
sent no token). Issues #9495 and #9496 both trace to this gap.

Plumb jwt.filer_signing.key into IamGrpcStore via a new SetAdminSigning
hook called from the admin server, and append a freshly minted Bearer
token to outgoing metadata on every call. The mint helper
security.GenJwtForFilerAdmin existed since #9442 but had no production
caller; this wires it up.

Add an integration test alongside grpc_store.go that runs a real
IamGrpcServer over a real grpc.Server listener and exercises the store
end-to-end: matching key succeeds, wrong key returns Unauthenticated,
no key returns Unauthenticated. Without the client-side token attach
the success path fails, so the regression cannot land again.

Chris Lu e77f8ae204 fix(s3api): route STS GetFederationToken to STS handler (#9157) (#9167)
* fix(s3api): route STS GetFederationToken requests to STS handler (#9157)

The STS GetFederationToken handler was implemented but never reachable.
Three routing gaps sent requests to the S3/IAM path instead of STS:

- No explicit mux route for Action=GetFederationToken in the URL query
- iamMatcher did not exclude GetFederationToken, so authenticated POSTs
  with Action in the form body were matched and dispatched to IAM
- UnifiedPostHandler only dispatched AssumeRole* and GetCallerIdentity
  to STS, leaving GetFederationToken to fall through to DoActions and
  return NotImplemented

Add the missing route, the matcher exclusion, and the dispatch branch.

Also wire TestSTS, TestAssumeRoleWithWebIdentity, and TestServiceAccount
into the s3-iam-tests workflow as a new "sts" matrix entry. Before this
change, none of test/s3/iam/s3_sts_get_federation_token_test.go's four
test functions ran in CI, which is why this regression shipped.

* test(iam): make orphaned STS/service-account tests pass under auth-enabled CI

Follow-up to wiring STS tests into CI: fixes several pre-existing issues
that made the newly-included tests fail locally.

Server fixes:
- weed/s3api/s3api_sts.go: handleGetFederationToken no longer 500s when
  the caller is a legacy S3-config identity (not in the IAM user store).
  Previously any GetPoliciesForUser error short-circuited to InternalError,
  which hard-failed every SigV4 caller using keys from -s3.config.
- weed/s3api/s3api_embedded_iam.go: CreateServiceAccount now generates IDs
  in the sa:<parent>:<uuid> format required by
  credential.ValidateServiceAccountId. The old "sa-XXXXXXXX" format failed
  the persistence-layer regex and caused every CreateServiceAccount call
  to return 500 once a filer-backed credential store validated the ID.

Test helpers:
- test/s3/iam/s3_sts_assume_role_test.go: callSTSAPIWithSigV4 no longer
  sets req.Header["Host"]. aws-sdk-go v1 v4.Signer already signs Host from
  req.URL.Host, and a manual Host header made the signer emit host;host in
  SignedHeaders, producing SignatureDoesNotMatch. Updated missing_role_arn
  subtest to match the existing SeaweedFS behavior (user-context
  assumption).
- test/s3/iam/s3_service_account_test.go: callIAMAPI now SigV4-signs
  requests when STS_TEST_{ACCESS,SECRET}_KEY env vars are set. Unsigned
  IAM writes otherwise fall through to the STS fallback and return
  InvalidAction.

CI matrix:
- .github/workflows/s3-iam-tests.yml: skip
  TestServiceAccountLifecycle/use_service_account_credentials only. The
  rest of the service-account suite passes; that one subtest depends on a
  separate credential-reload issue where new ABIA keys briefly register
  into accessKeyIdent but aren't persisted to the filer, so they vanish
  on the next reload. Out of scope for the #9157 GetFederationToken fix.

* fix(credential): accept AWS IAM username chars in service-account IDs

Gemini review on #9167 pointed out that ServiceAccountIdPattern's
parent-user segment was more restrictive than an AWS IAM username:
`[A-Za-z0-9_-]` vs. IAM's `[\w+=,.@-]`. Realistic usernames with
`@`, `.`, `+`, `=`, or `,` (e.g. email-style principals) would fail
validation at the filer store even though the embedded IAM API
happily created them.

Broaden the regex to `[A-Za-z0-9_+=,.@-]` (matching the AWS IAM spec
at https://docs.aws.amazon.com/IAM/latest/APIReference/API_User.html)
and add a table-driven test that locks the expansion in.

* address PR review feedback on #9167

All five review items were valid; changes keyed to review bullets:

- weed/s3api/s3api_sts.go: handleGetFederationToken no longer swallows
  arbitrary policy-lookup failures. Only credential.ErrUserNotFound is
  treated leniently (the legacy-config SigV4 path); any other error now
  returns InternalError so we don't mint tokens with an incomplete
  policy set.
- weed/credential/grpc/grpc_identity.go: GetUser translates gRPC
  NotFound back to credential.ErrUserNotFound so errors.Is(...) above
  matches for gRPC-backed stores, not just memory/filer-direct.
- weed/s3api/s3api_embedded_iam.go: CreateServiceAccount now validates
  the generated saId against credential.ValidateServiceAccountId before
  returning. Surfaces a client 400 with the offending ID instead of the
  opaque 500 that used to bubble up from the persistence layer.
- weed/s3api/s3api_server_routing_test.go: seed a routing-test identity
  with a known AK/SK, sign TestRouting_GetFederationTokenAuthenticatedBody
  with aws-sdk-go v4.Signer so the request actually passes
  AuthSignatureOnly. Assert 503 ServiceUnavailable (from STSHandlers
  with no stsService) instead of just NotEqual(501) — 503 proves the
  dispatch reached STSHandlers.HandleSTSRequest.
- test/s3/iam/s3_service_account_test.go: callIAMAPI signs with
  service="iam" instead of "s3" (SeaweedFS verifies against whichever
  service the client signed with, but "iam" is semantically correct).
- weed/credential/validation_test.go: add positive rows for an
  uppercase parent (sa:ALICE:...) and a canonical hyphenated UUID
  suffix (sa:alice:123e4567-e89b-12d3-a456-426614174000).

The `CredentialManager` was updated to delegate these calls to the store.
Added common error variables for policy management.

* iam: implement managed policy methods in MemoryStore

Implemented `AttachUserPolicy`, `DetachUserPolicy`, and
`ListAttachedUserPolicies` in the MemoryStore.
Also ensured deep copying of identities includes PolicyNames.

Modified Postgres schema to include `policy_names` JSONB column in `users`.
Implemented `AttachUserPolicy`, `DetachUserPolicy`, and `ListAttachedUserPolicies`.
Updated user CRUD operations to handle policy names persistence.

* iam: implement managed policy methods in remaining stores

Implemented user policy management in:
- `FilerEtcStore` (partial implementation)
- `IamGrpcStore` (delegated via GetUser/UpdateUser)
- `PropagatingCredentialStore` (to broadcast updates)
Ensures cluster-wide consistency for policy attachments.

* s3api: refactor EmbeddedIamApi to use managed policy APIs

- Refactored `AttachUserPolicy`, `DetachUserPolicy`, and `ListAttachedUserPolicies`
  to use `e.credentialManager` directly.
- Fixed a critical error suppression bug in `ExecuteAction` that always
  returned success even on failure.
- Implemented robust error matching using string comparison fallbacks.
- Improved consistency by reloading configuration after policy changes.

* s3api: update and refine IAM integration tests

- Updated tests to use a real `MemoryStore`-backed `CredentialManager`.
- Refined test configuration synchronization using `sync.Once` and
  manual deep-copying to prevent state corruption.
- Improved `extractEmbeddedIamErrorCodeAndMessage` to handle more XML
  formats robustly.
- Adjusted test expectations to match current AWS IAM behavior.
