* S3: Implement IAM defaults and STS signing key fallback logic
* S3: Refactor startup order to init SSE-S3 key manager before IAM
* S3: Derive STS signing key from KEK using HKDF for security isolation
* S3: Document STS signing key fallback in security.toml
* fix(s3api): refine anonymous access logic and secure-by-default behavior
- Initialize anonymous identity by default in `NewIdentityAccessManagement` to prevent nil pointer exceptions.
- Ensure `ReplaceS3ApiConfiguration` preserves the anonymous identity if not present in the new configuration.
- Update `NewIdentityAccessManagement` signature to accept `filerClient`.
- In legacy mode (no policy engine), anonymous defaults to Deny (no actions), preserving secure-by-default behavior.
- Use specific `LookupAnonymous` method instead of generic map lookup.
- Update tests to accommodate signature changes and verify improved anonymous handling.
* feat(s3api): make IAM configuration optional
- Start S3 API server without a configuration file if `EnableIam` option is set.
- Default to `Allow` effect for policy engine when no configuration is provided (Zero-Config mode).
- Handle empty configuration path gracefully in `loadIAMManagerFromConfig`.
- Add integration test `iam_optional_test.go` to verify empty config behavior.
* fix(iamapi): fix signature mismatch in NewIdentityAccessManagementWithStore
* fix(iamapi): properly initialize FilerClient instead of passing nil
* fix(iamapi): properly initialize filer client for IAM management
- Instead of passing `nil`, construct a `wdclient.FilerClient` using the provided `Filers` addresses.
- Ensure `NewIdentityAccessManagementWithStore` receives a valid `filerClient` to avoid potential nil pointer dereferences or limited functionality.
* clean: remove dead code in s3api_server.go
* refactor(s3api): improve IAM initialization, safety and anonymous access security
* fix(s3api): ensure IAM config loads from filer after client init
* fix(s3): resolve test failures in integration, CORS, and tagging tests
- Fix CORS tests by providing explicit anonymous permissions config
- Fix S3 integration tests by setting admin credentials in init
- Align tagging test credentials in CI with IAM defaults
- Added goroutine to retry IAM config load in iamapi server
* fix(s3): allow anonymous access to health targets and S3 Tables when identities are present
* fix(ci): use /healthz for Caddy health check in awscli tests
* iam, s3api: expose DefaultAllow from IAM and Policy Engine
This allows checking the global "Open by Default" configuration from
other components like S3 Tables.
* s3api/s3tables: support DefaultAllow in permission logic and handler
Updated CheckPermissionWithContext to respect the DefaultAllow flag
in PolicyContext. This enables "Open by Default" behavior for
unauthenticated access in zero-config environments. Added a targeted
unit test to verify the logic.
* s3api/s3tables: propagate DefaultAllow through handlers
Propagated the DefaultAllow flag to individual handlers for
namespaces, buckets, tables, policies, and tagging. This ensures
consistent "Open by Default" behavior across all S3 Tables API
endpoints.
* s3api: wire up DefaultAllow for S3 Tables API initialization
Updated registerS3TablesRoutes to query the global IAM configuration
and set the DefaultAllow flag on the S3 Tables API server. This
completes the end-to-end propagation required for anonymous access in
zero-config environments. Added a SetDefaultAllow method to
S3TablesApiServer to facilitate this.
* s3api: fix tests by adding DefaultAllow to mock IAM integrations
The IAMIntegration interface was updated to include DefaultAllow(),
breaking several mock implementations in tests. This commit fixes
the build errors by adding the missing method to the mocks.

* Fix: Populate Claims from STS session RequestContext for policy variable substitution
When using STS temporary credentials (from AssumeRoleWithWebIdentity) with
AWS Signature V4 authentication, JWT claims like preferred_username were
not available for bucket policy variable substitution (e.g., ${jwt:preferred_username}).
Root Cause:
- STS session tokens store user claims in the req_ctx field (added in PR #8079)
- validateSTSSessionToken() created Identity but didn't populate Claims field
- authorizeWithIAM() created IAMIdentity but didn't copy Claims
- Policy engine couldn't resolve ${jwt:*} variables without claims
Changes:
1. auth_signature_v4.go: Extract claims from sessionInfo.RequestContext
and populate Identity.Claims in validateSTSSessionToken()
2. auth_credentials.go: Copy Claims when creating IAMIdentity in
authorizeWithIAM()
3. auth_sts_identity_test.go: Add TestSTSIdentityClaimsPopulation to
verify claims are properly populated from RequestContext
This enables bucket policies with JWT claim variables to work correctly
with STS temporary credentials obtained via AssumeRoleWithWebIdentity.
Fixes#8037
* Refactor: Idiomatic map population for STS claims
* Fix STS identity authorization by populating PolicyNames (#7985)
This commit fixes GitHub issue #7985 where STS-assumed identities
received empty identity.Actions, causing all S3 operations to be denied
even when the role had valid IAM policies attached.
Changes:
1. Populate PolicyNames field from sessionInfo.Policies in
validateSTSSessionToken() to enable IAM-based authorization for
STS identities
2. Fix bucket+objectKey path construction in canDo() method to include
proper slash separator between bucket and object key
3. Add comprehensive test suite to validate the fix and prevent
regression
The fix ensures that STS-assumed identities are properly authorized
through the IAM path when iamIntegration is available, allowing roles
with valid IAM policies to perform S3 operations as expected.
* Update STS identity tests to be more rigorous and use actual implementation path
* Fix regression in canDo() path concatenation
The previous fix blindly added a slash separator, which caused double
slashes when objectKey already started with a slash (common in existing
tests and some code paths). This broke TestCanDo and
TestObjectLevelListPermissions.
This commit updates the logic to only add the slash separator if
objectKey is not empty and does not already start with a slash.
This fixes the regressions while maintaining the fix for issue #7985.
* Refactor STS identity tests: extract helpers and simplify redundant logic
- Extracted setupTestSTSService and newTestIdentity helper functions
- Removed redundant if-else verification blocks that were already covered by assertions
- Cleaned up test cases to improve maintainability as suggested in code review.
* Add canDo() verification to STS identity tests
Address code review suggestion: verify that identities with empty
Actions correctly return false for canDo() checks, which confirms the
behavior that forces authorization to fall back to the IAM path.
* Simplify TestCanDoPathConstruction variable names
Rename expectedPath to fullPath and simplify logging/assertion logic
based on code review feedback.
* Refactor path construction and logging in canDo()
- Compute fullPath early and use it for logging to prevent double slashes
- Update TestCanDoPathConstruction to use robust path verification
- Add test case for objectKey with leading slash to ensure correct handling
