Michał Szynkiewicz	53048ffffb	Add md5 checksum validation support on PutObject and UploadPart (#8367 ) * Add md5 checksum validation support on PutObject and UploadPart Per the S3 specification, when a client sends a Content-MD5 header, the server must compare it against the MD5 of the received body and return BadDigest (HTTP 400) if they don't match. SeaweedFS was silently accepting objects with incorrect Content-MD5 headers, which breaks data integrity verification for clients that rely on this feature (e.g. boto3). The error infrastructure (ErrBadDigest, ErrMsgBadDigest) already existed from PR #7306 but was never wired to an actual check. This commit adds MD5 verification in putToFiler after the body is streamed and the MD5 is computed, and adds Content-MD5 header validation to PutObjectPartHandler (matching PutObjectHandler). Orphaned chunks are cleaned up on mismatch. Refs: https://github.com/seaweedfs/seaweedfs/discussions/3908 * handle SSE, add uploadpart test * s3 integration test: fix typo and add multipart upload checksum test * s3api: move validateContentMd5 after GetBucketAndObject in PutObjectPartHandler * s3api: move validateContentMd5 after GetBucketAndObject in PutObjectHandler * s3api: fix MD5 validation for SSE uploads and logging in putToFiler * add SSE test with checksum validation - mostly ai-generated * Update s3_integration_test.go * Address S3 integration test feedback: fix typos, rename variables, add verification steps, and clean up comments. --------- Co-authored-by: Chris Lu <chris.lu@gmail.com>	3 days ago
Chris Lu	0d8588e3ae	S3: Implement IAM defaults and STS signing key fallback (#8348 ) * 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. * env * ensure ports * env * env * fix default allow * add one more test using non-anonymous user * debug * add more debug * less logs	5 days ago
Chris Lu	551a31e156	Implement IAM propagation to S3 servers (#8130 ) * Implement IAM propagation to S3 servers - Add PropagatingCredentialStore to propagate IAM changes to S3 servers via gRPC - Add Policy management RPCs to S3 proto and S3ApiServer - Update CredentialManager to use PropagatingCredentialStore when MasterClient is available - Wire FilerServer to enable propagation * Implement parallel IAM propagation and fix S3 cluster registration - Parallelized IAM change propagation with 10s timeout. - Refined context usage in PropagatingCredentialStore. - Added S3Type support to cluster node management. - Enabled S3 servers to register with gRPC address to the master. - Ensured IAM configuration reload after policy updates via gRPC. * Optimize IAM propagation with direct in-memory cache updates * Secure IAM propagation: Use metadata to skip persistence only on propagation * pb: refactor IAM and S3 services for unidirectional IAM propagation - Move SeaweedS3IamCache service from iam.proto to s3.proto. - Remove legacy IAM management RPCs and empty SeaweedS3 service from s3.proto. - Enforce that S3 servers only use the synchronization interface. * pb: regenerate Go code for IAM and S3 services Updated generated code following the proto refactoring of IAM synchronization services. * s3api: implement read-only mode for Embedded IAM API - Add readOnly flag to EmbeddedIamApi to reject write operations via HTTP. - Enable read-only mode by default in S3ApiServer. - Handle AccessDenied error in writeIamErrorResponse. - Embed SeaweedS3IamCacheServer in S3ApiServer. * credential: refactor PropagatingCredentialStore for unidirectional IAM flow - Update to use s3_pb.SeaweedS3IamCacheClient for propagation to S3 servers. - Propagate full Identity object via PutIdentity for consistency. - Remove redundant propagation of specific user/account/policy management RPCs. - Add timeout context for propagation calls. * s3api: implement SeaweedS3IamCacheServer for unidirectional sync - Update S3ApiServer to implement the cache synchronization gRPC interface. - Methods (PutIdentity, RemoveIdentity, etc.) now perform direct in-memory cache updates. - Register SeaweedS3IamCacheServer in command/s3.go. - Remove registration for the legacy and now empty SeaweedS3 service. * s3api: update tests for read-only IAM and propagation - Added TestEmbeddedIamReadOnly to verify rejection of write operations in read-only mode. - Update test setup to pass readOnly=false to NewEmbeddedIamApi in routing tests. - Updated EmbeddedIamApiForTest helper with read-only checks matching production behavior. * s3api: add back temporary debug logs for IAM updates Log IAM updates received via: - gRPC propagation (PutIdentity, PutPolicy, etc.) - Metadata configuration reloads (LoadS3ApiConfigurationFromCredentialManager) - Core identity management (UpsertIdentity, RemoveIdentity) * IAM: finalize propagation fix with reduced logging and clarified architecture * Allow configuring IAM read-only mode for S3 server integration tests * s3api: add defensive validation to UpsertIdentity * s3api: fix log message to reference correct IAM read-only flag * test/s3/iam: ensure WaitForS3Service checks for IAM write permissions * test: enable writable IAM in Makefile for integration tests * IAM: add GetPolicy/ListPolicies RPCs to s3.proto * S3: add GetBucketPolicy and ListBucketPolicies helpers * S3: support storing generic IAM policies in IdentityAccessManagement * S3: implement IAM policy RPCs using IdentityAccessManagement * IAM: fix stale user identity on rename propagation	4 weeks ago
Chris Lu	d664ca5ed3	fix: IAM authentication with AWS Signature V4 and environment credentials (#8099 ) * fix: IAM authentication with AWS Signature V4 and environment credentials Three key fixes for authenticated IAM requests to work: 1. Fix request body consumption before signature verification - iamMatcher was calling r.ParseForm() which consumed POST body - This broke AWS Signature V4 verification on subsequent reads - Now only check query string in matcher, preserving body for verification - File: weed/s3api/s3api_server.go 2. Preserve environment variable credentials across config reloads - After IAM mutations, config reload overwrote env var credentials - Extract env var loading into loadEnvironmentVariableCredentials() - Call after every config reload to persist credentials - File: weed/s3api/auth_credentials.go 3. Add authenticated IAM tests and test infrastructure - New TestIAMAuthenticated suite with AWS SDK + Signature V4 - Dynamic port allocation for independent test execution - Flag reset to prevent state leakage between tests - CI workflow to run S3 and IAM tests separately - Files: test/s3/example/, .github/workflows/s3-example-integration-tests.yml All tests pass: - TestIAMCreateUser (unauthenticated) - TestIAMAuthenticated (with AWS Signature V4) - S3 integration tests fmt * chore: rename test/s3/example to test/s3/normal * simplify: CI runs all integration tests in single job * Update s3-example-integration-tests.yml * ci: run each test group separately to avoid raft registry conflicts	4 weeks ago
