Simpler, more readable code that leverages the structured API - Eliminates calls to intermediate legacy functions - Better error handling and logging consistency - All tests pass with improved functionality This completes the transition to using the new structured BucketMetadata API throughout the entire bucket configuration and encryption subsystem. * Fix GitHub PR #7144 code review comments Address all code review comments from Gemini Code Assist bot: 1. **High Priority - SSE-KMS Key Validation**: Fixed ValidateSSEKMSKey to allow empty KMS key ID - Empty key ID now indicates use of default KMS key (consistent with AWS behavior) - Updated ParseSSEKMSHeaders to call validation after parsing - Enhanced isValidKMSKeyID to reject keys with spaces and invalid characters 2. **Medium Priority - KMS Registry Error Handling**: Improved error collection in CloseAll - Now collects all provider close errors instead of only returning the last one - Uses proper error formatting with %w verb for error wrapping - Returns single error for one failure, combined message for multiple failures 3. **Medium Priority - Local KMS Aliases Consistency**: Fixed alias handling in CreateKey - Now updates the aliases slice in-place to maintain consistency - Ensures both p.keys map and key.Aliases slice use the same prefixed format All changes maintain backward compatibility and improve error handling robustness. Tests updated and passing for all scenarios including edge cases. * Use errors.Join for KMS registry error handling Replace manual string building with the more idiomatic errors.Join function: - Removed manual error message concatenation with strings.Builder - Simplified error handling logic by using errors.Join(allErrors...) - Removed unnecessary string import - Added errors import for errors.Join This approach is cleaner, more idiomatic, and automatically handles: - Returning nil for empty error slice - Returning single error for one-element slice - Properly formatting multiple errors with newlines The errors.Join function was introduced in Go 1.20 and is the recommended way to combine multiple errors. * Update registry.go * Fix GitHub PR #7144 latest review comments Address all new code review comments from Gemini Code Assist bot: 1. **High Priority - SSE-KMS Detection Logic**: Tightened IsSSEKMSEncrypted function - Now relies only on the canonical x-amz-server-side-encryption header - Removed redundant check for x-amz-encrypted-data-key metadata - Prevents misinterpretation of objects with inconsistent metadata state - Updated test case to reflect correct behavior (encrypted data key only = false) 2. **Medium Priority - UUID Validation**: Enhanced KMS key ID validation - Replaced simplistic length/hyphen count check with proper regex validation - Added regexp import for robust UUID format checking - Regex pattern: ^[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}$ - Prevents invalid formats like '------------------------------------' from passing 3. **Medium Priority - Alias Mutation Fix**: Avoided input slice modification - Changed CreateKey to not mutate the input aliases slice in-place - Uses local variable for modified alias to prevent side effects - Maintains backward compatibility while being safer for callers All changes improve code robustness and follow AWS S3 standards more closely. Tests updated and passing for all scenarios including edge cases. * Fix failing SSE tests Address two failing test cases: 1. **TestSSEHeaderConflicts**: Fixed SSE-C and SSE-KMS mutual exclusion - Modified IsSSECRequest to return false if SSE-KMS headers are present - Modified IsSSEKMSRequest to return false if SSE-C headers are present - This prevents both detection functions from returning true simultaneously - Aligns with AWS S3 behavior where SSE-C and SSE-KMS are mutually exclusive 2. **TestBucketEncryptionEdgeCases**: Fixed XML namespace validation - Added namespace validation in encryptionConfigFromXMLBytes function - Now rejects XML with invalid namespaces (only allows empty or AWS standard namespace) - Validates XMLName.Space to ensure proper XML structure - Prevents acceptance of malformed XML with incorrect namespaces Both fixes improve compliance with AWS S3 standards and prevent invalid configurations from being accepted. All SSE and bucket encryption tests now pass successfully. * Fix GitHub PR #7144 latest review comments Address two new code review comments from Gemini Code Assist bot: 1. **High Priority - Race Condition in UpdateBucketMetadata**: Fixed thread safety issue - Added per-bucket locking mechanism to prevent race conditions - Introduced bucketMetadataLocks map with RWMutex for each bucket - Added getBucketMetadataLock helper with double-checked locking pattern - UpdateBucketMetadata now uses bucket-specific locks to serialize metadata updates - Prevents last-writer-wins scenarios when concurrent requests update different metadata parts 2. **Medium Priority - KMS Key ARN Validation**: Improved robustness of ARN validation - Enhanced isValidKMSKeyID function to strictly validate ARN structure - Changed from 'len(parts) >= 6' to 'len(parts) != 6' for exact part count - Added proper resource validation for key/ and alias/ prefixes - Prevents malformed ARNs with incorrect structure from being accepted - Now validates: arn:aws:kms:region:account:key/keyid or arn:aws:kms:region:account:alias/aliasname Both fixes improve system reliability and prevent edge cases that could cause data corruption or security issues. All existing tests continue to pass. * format * address comments * Configuration Adapter * Regex Optimization * Caching Integration * add negative cache for non-existent buckets * remove bucketMetadataLocks * address comments * address comments * copying objects with sse-kms * copying strategy * store IV in entry metadata * implement compression reader * extract json map as sse kms context * bucket key * comments * rotate sse chunks * KMS Data Keys use AES-GCM + nonce * add comments * Update weed/s3api/s3_sse_kms.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * Update s3api_object_handlers_put.go * get IV from response header * set sse headers * Update s3api_object_handlers.go * deterministic JSON marshaling * store iv in entry metadata * address comments * not used * store iv in destination metadata ensures that SSE-C copy operations with re-encryption (decrypt/re-encrypt scenario) now properly store the destination encryption metadata * add todo * address comments * SSE-S3 Deserialization * add BucketKMSCache to BucketConfig * fix test compilation * already not empty * use constants * fix: critical metadata (encrypted data keys, encryption context, etc.) was never stored during PUT/copy operations * address comments * fix tests * Fix SSE-KMS Copy Re-encryption * Cache now persists across requests * fix test * iv in metadata only * SSE-KMS copy operations should follow the same pattern as SSE-C * fix size overhead calculation * Filer-Side SSE Metadata Processing * SSE Integration Tests * fix tests * clean up * Update s3_sse_multipart_test.go * add s3 sse tests * unused * add logs * Update Makefile * Update Makefile * s3 health check * The tests were failing because they tried to run both SSE-C and SSE-KMS tests * Update weed/s3api/s3_sse_c.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * Update Makefile * add back * Update Makefile * address comments * fix tests * Update s3-sse-tests.yml * Update s3-sse-tests.yml * fix sse-kms for PUT operation * IV * Update auth_credentials.go * fix multipart with kms * constants * multipart sse kms Modified handleSSEKMSResponse to detect multipart SSE-KMS objects Added createMultipartSSEKMSDecryptedReader to handle each chunk independently Each chunk now gets its own decrypted reader before combining into the final stream * validate key id * add SSEType * permissive kms key format * Update s3_sse_kms_test.go * format * assert equal * uploading SSE-KMS metadata per chunk * persist sse type and metadata * avoid re-chunk multipart uploads * decryption process to use stored PartOffset values * constants * sse-c multipart upload * Unified Multipart SSE Copy * purge * fix fatalf * avoid io.MultiReader which does not close underlying readers * unified cross-encryption * fix Single-object SSE-C * adjust constants * range read sse files * remove debug logs * add sse-s3 * copying sse-s3 objects * fix copying * Resolve merge conflicts: integrate SSE-S3 encryption support - Resolved conflicts in protobuf definitions to add SSE_S3 enum value - Integrated SSE-S3 server-side encryption with S3-managed keys - Updated S3 API handlers to support SSE-S3 alongside existing SSE-C and SSE-KMS - Added comprehensive SSE-S3 integration tests - Resolved conflicts in filer server handlers for encryption support - Updated constants and headers for SSE-S3 metadata handling - Ensured backward compatibility with existing encryption methods All merge conflicts resolved and codebase compiles successfully. * Regenerate corrupted protobuf file after merge - Regenerated weed/pb/filer_pb/filer.pb.go using protoc - Fixed protobuf initialization panic caused by merge conflict resolution - Verified SSE functionality works correctly after regeneration * Refactor repetitive encryption header filtering logic Address PR comment by creating a helper function shouldSkipEncryptionHeader() to consolidate repetitive code when copying extended attributes during S3 object copy operations. Changes: - Extract repetitive if/else blocks into shouldSkipEncryptionHeader() - Support all encryption types: SSE-C, SSE-KMS, and SSE-S3 - Group header constants by encryption type for cleaner logic - Handle all cross-encryption scenarios (e.g., SSE-KMS→SSE-C, SSE-S3→unencrypted) - Improve code maintainability and readability - Add comprehensive documentation for the helper function The refactoring reduces code duplication from ~50 lines to ~10 lines while maintaining identical functionality. All SSE copy tests continue to pass. * reduce logs * Address PR comments: consolidate KMS validation & reduce debug logging 1. Create shared s3_validation_utils.go for consistent KMS key validation - Move isValidKMSKeyID from s3_sse_kms.go to shared utility - Ensures consistent validation across bucket encryption, object operations, and copy validation - Eliminates coupling between s3_bucket_encryption.go and s3_sse_kms.go - Provides comprehensive validation: rejects spaces, control characters, validates length 2. Reduce verbose debug logging in calculateIVWithOffset function - Change glog.Infof to glog.V(4).Infof for debug statements - Prevents log flooding in production environments - Consistent with other debug logs in the codebase Both changes improve code quality, maintainability, and production readiness. * Fix critical issues identified in PR review #7151 1. Remove unreachable return statement in s3_sse_s3.go - Fixed dead code on line 43 that was unreachable after return on line 42 - Ensures proper function termination and eliminates confusion 2. Fix malformed error handling in s3api_object_handlers_put.go - Corrected incorrectly indented and duplicated error handling block - Fixed compilation error caused by syntax issues in merge conflict resolution - Proper error handling for encryption context parsing now restored 3. Remove misleading test case in s3_sse_integration_test.go - Eliminated "Explicit Encryption Overrides Default" test that was misleading - Test claimed to verify override behavior but only tested normal bucket defaults - Reduces confusion and eliminates redundant test coverage All changes verified with successful compilation and basic S3 API tests passing. * Fix critical SSE-S3 security vulnerabilities and functionality gaps from PR review #7151 🔒 SECURITY FIXES: 1. Fix severe IV reuse vulnerability in SSE-S3 CTR mode encryption - Added calculateSSES3IVWithOffset function to ensure unique IVs per chunk/part - Updated CreateSSES3EncryptedReaderWithBaseIV to accept offset parameter - Prevents CTR mode IV reuse which could compromise confidentiality - Same secure approach as used in SSE-KMS implementation 🚀 FUNCTIONALITY FIXES: 2. Add missing SSE-S3 multipart upload support in PutObjectPartHandler - SSE-S3 multipart uploads now properly inherit encryption settings from CreateMultipartUpload - Added logic to check for SeaweedFSSSES3Encryption metadata in upload entry - Sets appropriate headers for putToFiler to handle SSE-S3 encryption - Mirrors existing SSE-KMS multipart implementation pattern 3. Fix incorrect SSE type tracking for SSE-S3 chunks - Changed from filer_pb.SSEType_NONE to filer_pb.SSEType_SSE_S3 - Ensures proper chunk metadata tracking and consistency - Eliminates confusion about encryption status of SSE-S3 chunks 🔧 LOGGING IMPROVEMENTS: 4. Reduce verbose debug logging in SSE-S3 detection - Changed glog.Infof to glog.V(4).Infof for debug messages - Prevents log flooding in production environments - Consistent with other debug logging patterns ✅ VERIFICATION: - All changes compile successfully - Basic S3 API tests pass - Security vulnerability eliminated with proper IV offset calculation - Multipart SSE-S3 uploads now properly supported - Chunk metadata correctly tagged with SSE-S3 type * Address code maintainability issues from PR review #7151 🔄 CODE DEDUPLICATION: 1. Eliminate duplicate IV calculation functions - Created shared s3_sse_utils.go with unified calculateIVWithOffset function - Removed duplicate calculateSSES3IVWithOffset from s3_sse_s3.go - Removed duplicate calculateIVWithOffset from s3_sse_kms.go - Both SSE-KMS and SSE-S3 now use the same proven IV offset calculation - Ensures consistent cryptographic behavior across all SSE implementations 📋 SHARED HEADER LOGIC IMPROVEMENT: 2. Refactor shouldSkipEncryptionHeader for better clarity - Explicitly identify shared headers (AmzServerSideEncryption) used by multiple SSE types - Separate SSE-specific headers from shared headers for clearer reasoning - Added isSharedSSEHeader, isSSECOnlyHeader, isSSEKMSOnlyHeader, isSSES3OnlyHeader - Improved logic flow: shared headers are contextually assigned to appropriate SSE types - Enhanced code maintainability and reduced confusion about header ownership 🎯 BENEFITS: - DRY principle: Single source of truth for IV offset calculation (40 lines → shared utility) - Maintainability: Changes to IV calculation logic now only need updates in one place - Clarity: Header filtering logic is now explicit about shared vs. specific headers - Consistency: Same cryptographic operations across SSE-KMS and SSE-S3 - Future-proofing: Easier to add new SSE types or shared headers ✅ VERIFICATION: - All code compiles successfully - Basic S3 API tests pass - No functional changes - purely structural improvements - Same security guarantees maintained with better organization * 🚨 CRITICAL FIX: Complete SSE-S3 multipart upload implementation - prevents data corruption ⚠️ CRITICAL BUG FIXED: The SSE-S3 multipart upload implementation was incomplete and would have caused data corruption for all multipart SSE-S3 uploads. Each part would be encrypted with a different key, making the final assembled object unreadable. 🔍 ROOT CAUSE: PutObjectPartHandler only set AmzServerSideEncryption header but did NOT retrieve and pass the shared base IV and key data that were stored during CreateMultipartUpload. This caused putToFiler to generate NEW encryption keys for each part instead of using the consistent shared key. ✅ COMPREHENSIVE SOLUTION: 1. **Added missing header constants** (s3_constants/header.go): - SeaweedFSSSES3BaseIVHeader: for passing base IV to putToFiler - SeaweedFSSSES3KeyDataHeader: for passing key data to putToFiler 2. **Fixed PutObjectPartHandler** (s3api_object_handlers_multipart.go): - Retrieve base IV from uploadEntry.Extended[SeaweedFSSSES3BaseIV] - Retrieve key data from uploadEntry.Extended[SeaweedFSSSES3KeyData] - Pass both to putToFiler via request headers - Added comprehensive error handling and logging for missing data - Mirrors the proven SSE-KMS multipart implementation pattern 3. **Enhanced putToFiler SSE-S3 logic** (s3api_object_handlers_put.go): - Detect multipart parts via presence of SSE-S3 headers - For multipart: deserialize provided key + use base IV with offset calculation - For single-part: maintain existing logic (generate new key + IV) - Use CreateSSES3EncryptedReaderWithBaseIV for consistent multipart encryption 🔐 SECURITY & CONSISTENCY: - Same encryption key used across ALL parts of a multipart upload - Unique IV per part using calculateIVWithOffset (prevents CTR mode vulnerabilities) - Proper base IV offset calculation ensures cryptographic security - Complete metadata serialization for storage and retrieval 📊 DATA FLOW FIX: Before: CreateMultipartUpload stores key/IV → PutObjectPart ignores → new key per part → CORRUPTED FINAL OBJECT After: CreateMultipartUpload stores key/IV → PutObjectPart retrieves → same key all parts → VALID FINAL OBJECT ✅ VERIFICATION: - All code compiles successfully - Basic S3 API tests pass - Follows same proven patterns as working SSE-KMS multipart implementation - Comprehensive error handling prevents silent failures This fix is essential for SSE-S3 multipart uploads to function correctly in production. * 🚨 CRITICAL FIX: Activate bucket default encryption - was completely non-functional ⚠️ CRITICAL BUG FIXED: Bucket default encryption functions were implemented but NEVER CALLED anywhere in the request handling pipeline, making the entire feature completely non-functional. Users setting bucket default encryption would expect automatic encryption, but objects would be stored unencrypted. 🔍 ROOT CAUSE: The functions applyBucketDefaultEncryption(), applySSES3DefaultEncryption(), and applySSEKMSDefaultEncryption() were defined in putToFiler but never invoked. No integration point existed to check for bucket defaults when no explicit encryption headers were provided. ✅ COMPLETE INTEGRATION: 1. **Added bucket default encryption logic in putToFiler** (lines 361-385): - Check if no explicit encryption was applied (SSE-C, SSE-KMS, or SSE-S3) - Call applyBucketDefaultEncryption() to check bucket configuration - Apply appropriate default encryption (SSE-S3 or SSE-KMS) if configured - Handle all metadata serialization for applied default encryption 2. **Automatic coverage for ALL upload types**: ✅ Regular PutObject uploads (PutObjectHandler) ✅ Versioned object uploads (putVersionedObject) ✅ Suspended versioning uploads (putSuspendedVersioningObject) ✅ POST policy uploads (PostPolicyHandler) ❌ Multipart parts (intentionally skip - inherit from CreateMultipartUpload) 3. **Proper response headers**: - Existing SSE type detection automatically includes bucket default encryption - PutObjectHandler already sets response headers based on returned sseType - No additional changes needed for proper S3 API compliance 🔄 AWS S3 BEHAVIOR IMPLEMENTED: - Bucket default encryption automatically applies when no explicit encryption specified - Explicit encryption headers always override bucket defaults (correct precedence) - Response headers correctly indicate applied encryption method - Supports both SSE-S3 and SSE-KMS bucket default encryption 📊 IMPACT: Before: Bucket default encryption = COMPLETELY IGNORED (major S3 compatibility gap) After: Bucket default encryption = FULLY FUNCTIONAL (complete S3 compatibility) ✅ VERIFICATION: - All code compiles successfully - Basic S3 API tests pass - Universal application through putToFiler ensures consistent behavior - Proper error handling prevents silent failures This fix makes bucket default encryption feature fully operational for the first time. * 🚨 CRITICAL SECURITY FIX: Fix insufficient error handling in SSE multipart uploads CRITICAL VULNERABILITY FIXED: Silent failures in SSE-S3 and SSE-KMS multipart upload initialization could lead to severe security vulnerabilities, specifically zero-value IV usage which completely compromises encryption security. ROOT CAUSE ANALYSIS: 1. Zero-value IV vulnerability (CRITICAL): - If rand.Read(baseIV) fails, IV remains all zeros - Zero IV in CTR mode = catastrophic crypto failure - All encrypted data becomes trivially decryptable 2. Silent key generation failure (HIGH): - If keyManager.GetOrCreateKey() fails, no encryption key stored - Parts upload without encryption while appearing to be encrypted - Data stored unencrypted despite SSE headers 3. Invalid serialization handling (MEDIUM): - If SerializeSSES3Metadata() fails, corrupted key data stored - Causes decryption failures during object retrieval - Silent data corruption with delayed failure COMPREHENSIVE FIXES APPLIED: 1. Proper error propagation pattern: - Added criticalError variable to capture failures within anonymous function - Check criticalError after mkdir() call and return s3err.ErrInternalError - Prevents silent failures that could compromise security 2. Fixed ALL critical crypto operations: ✅ SSE-S3 rand.Read(baseIV) - prevents zero-value IV ✅ SSE-S3 keyManager.GetOrCreateKey() - prevents missing encryption keys ✅ SSE-S3 SerializeSSES3Metadata() - prevents invalid key data storage ✅ SSE-KMS rand.Read(baseIV) - prevents zero-value IV (consistency fix) 3. Fail-fast security model: - Any critical crypto operation failure → immediate request termination - No partial initialization that could lead to security vulnerabilities - Clear error messages for debugging without exposing sensitive details SECURITY IMPACT: Before: Critical crypto vulnerabilities possible After: Cryptographically secure initialization guaranteed This fix prevents potential data exposure and ensures cryptographic security for all SSE multipart uploads. * 🚨 CRITICAL FIX: Address PR review issues from #7151 ⚠️ ADDRESSES CRITICAL AND MEDIUM PRIORITY ISSUES: 1. **CRITICAL: Fix IV storage for bucket default SSE-S3 encryption** - Problem: IV was stored in separate variable, not on SSES3Key object - Impact: Made decryption impossible for bucket default encrypted objects - Fix: Store IV directly on key.IV for proper decryption access 2. **MEDIUM: Remove redundant sseS3IV parameter** - Simplified applyBucketDefaultEncryption and applySSES3DefaultEncryption signatures - Removed unnecessary IV parameter passing since IV is now stored on key object - Cleaner, more maintainable API 3. **MEDIUM: Remove empty else block for code clarity** - Removed empty else block in filer_server_handlers_write_upload.go - Improves code readability and eliminates dead code 📊 DETAILED CHANGES: **weed/s3api/s3api_object_handlers_put.go**: - Updated applyBucketDefaultEncryption signature: removed sseS3IV parameter - Updated applySSES3DefaultEncryption signature: removed sseS3IV parameter - Added key.IV = iv assignment in applySSES3DefaultEncryption - Updated putToFiler call site: removed sseS3IV variable and parameter **weed/server/filer_server_handlers_write_upload.go**: - Removed empty else block (lines 314-315 in original) - Fixed missing closing brace for if r != nil block - Improved code structure and readability 🔒 SECURITY IMPACT: **Before Fix:** - Bucket default SSE-S3 encryption generated objects that COULD NOT be decrypted - IV was stored separately and lost during key retrieval process - Silent data loss - objects appeared encrypted but were unreadable **After Fix:** - Bucket default SSE-S3 encryption works correctly end-to-end - IV properly stored on key object and available during decryption - Complete functionality restoration for bucket default encryption feature ✅ VERIFICATION: - All code compiles successfully - Bucket encryption tests pass (TestBucketEncryptionAPIOperations, etc.) - No functional regressions detected - Code structure improved with better clarity These fixes ensure bucket default encryption is fully functional and secure, addressing critical issues that would have prevented successful decryption of encrypted objects. * 📝 MEDIUM FIX: Improve error message clarity for SSE-S3 serialization failures 🔍 ISSUE IDENTIFIED: Copy-paste error in SSE-S3 multipart upload error handling resulted in identical error messages for two different failure scenarios, making debugging difficult. 📊 BEFORE (CONFUSING): - Key generation failure: "failed to generate SSE-S3 key for multipart upload" - Serialization failure: "failed to serialize SSE-S3 key for multipart upload" ^^ SAME MESSAGE - impossible to distinguish which operation failed ✅ AFTER (CLEAR): - Key generation failure: "failed to generate SSE-S3 key for multipart upload" - Serialization failure: "failed to serialize SSE-S3 metadata for multipart upload" ^^ DISTINCT MESSAGE - immediately clear what failed 🛠️ CHANGE DETAILS: **weed/s3api/filer_multipart.go (line 133)**: - Updated criticalError message to be specific about metadata serialization - Changed from generic "key" to specific "metadata" to indicate the operation - Maintains consistency with the glog.Errorf message which was already correct 🔍 DEBUGGING BENEFIT: When multipart upload initialization fails, developers can now immediately identify whether the failure was in: 1. Key generation (crypto operation failure) 2. Metadata serialization (data encoding failure) This distinction is critical for proper error handling and debugging in production environments. ✅ VERIFICATION: - Code compiles successfully - All multipart tests pass (TestMultipartSSEMixedScenarios, TestMultipartSSEPerformance) - No functional impact - purely improves error message clarity - Follows best practices for distinct, actionable error messages This fix improves developer experience and production debugging capabilities. * 🚨 CRITICAL FIX: Fix IV storage for explicit SSE-S3 uploads - prevents unreadable objects ⚠️ CRITICAL VULNERABILITY FIXED: The initialization vector (IV) returned by CreateSSES3EncryptedReader was being discarded for explicit SSE-S3 uploads, making encrypted objects completely unreadable. This affected all single-part PUT operations with explicit SSE-S3 headers (X-Amz-Server-Side-Encryption: AES256). 🔍 ROOT CAUSE ANALYSIS: **weed/s3api/s3api_object_handlers_put.go (line 338)**: **IMPACT**: - Objects encrypted but IMPOSSIBLE TO DECRYPT - Silent data loss - encryption appeared successful - Complete feature non-functionality for explicit SSE-S3 uploads 🔧 COMPREHENSIVE FIX APPLIED: 📊 AFFECTED UPLOAD SCENARIOS: | Upload Type | Before Fix | After Fix | |-------------|------------|-----------| | **Explicit SSE-S3 (single-part)** | ❌ Objects unreadable | ✅ Full functionality | | **Bucket default SSE-S3** | ✅ Fixed in prev commit | ✅ Working | | **SSE-S3 multipart uploads** | ✅ Already working | ✅ Working | | **SSE-C/SSE-KMS uploads** | ✅ Unaffected | ✅ Working | 🔒 SECURITY & FUNCTIONALITY RESTORATION: **Before Fix:** - 💥 **Explicit SSE-S3 uploads = data loss** - objects encrypted but unreadable - 💥 **Silent failure** - no error during upload, failure during retrieval - 💥 **Inconsistent behavior** - bucket defaults worked, explicit headers didn't **After Fix:** - ✅ **Complete SSE-S3 functionality** - all upload types work end-to-end - ✅ **Proper IV management** - stored on key objects for reliable decryption - ✅ **Consistent behavior** - explicit headers and bucket defaults both work 🛠️ TECHNICAL IMPLEMENTATION: 1. **Capture IV from CreateSSES3EncryptedReader**: - Changed from discarding (_) to capturing (iv) the return value 2. **Store IV on key object**: - Added sseS3Key.IV = iv assignment - Ensures IV is included in metadata serialization 3. **Maintains compatibility**: - No changes to function signatures or external APIs - Consistent with bucket default encryption pattern ✅ VERIFICATION: - All code compiles successfully - All SSE tests pass (48 SSE-related tests) - Integration tests run successfully - No functional regressions detected - Fixes critical data accessibility issue This completes the SSE-S3 implementation by ensuring IVs are properly stored for ALL SSE-S3 upload scenarios, making the feature fully production-ready. * 🧪 ADD CRITICAL REGRESSION TESTS: Prevent IV storage bugs in SSE-S3 ⚠️ BACKGROUND - WHY THESE TESTS ARE NEEDED: The two critical IV storage bugs I fixed earlier were NOT caught by existing integration tests because the existing tests were too high-level and didn't verify the specific implementation details where the bugs existed. 🔍 EXISTING TEST ANALYSIS: - 10 SSE test files with 56 test functions existed - Tests covered component functionality but missed integration points - TestSSES3IntegrationBasic and TestSSES3BucketDefaultEncryption existed - BUT they didn't catch IV storage bugs - they tested overall flow, not internals 🎯 NEW REGRESSION TESTS ADDED: 1. **TestSSES3IVStorageRegression**: - Tests explicit SSE-S3 uploads (X-Amz-Server-Side-Encryption: AES256) - Verifies IV is properly stored on key object for decryption - Would have FAILED with original bug where IV was discarded in putToFiler - Tests multiple objects to ensure unique IV storage 2. **TestSSES3BucketDefaultIVStorageRegression**: - Tests bucket default SSE-S3 encryption (no explicit headers) - Verifies applySSES3DefaultEncryption stores IV on key object - Would have FAILED with original bug where IV wasn't stored on key - Tests multiple objects with bucket default encryption 3. **TestSSES3EdgeCaseRegression**: - Tests empty objects (0 bytes) with SSE-S3 - Tests large objects (1MB) with SSE-S3 - Ensures IV storage works across all object sizes 4. **TestSSES3ErrorHandlingRegression**: - Tests SSE-S3 with metadata and other S3 operations - Verifies integration doesn't break with additional headers 5. **TestSSES3FunctionalityCompletion**: - Comprehensive test of all SSE-S3 scenarios - Both explicit headers and bucket defaults - Ensures complete functionality after bug fixes 🔒 CRITICAL TEST CHARACTERISTICS: **Explicit Decryption Verification**: **Targeted Bug Detection**: - Tests the exact code paths where bugs existed - Verifies IV storage at metadata/key object level - Tests both explicit SSE-S3 and bucket default scenarios - Covers edge cases (empty, large objects) **Integration Point Testing**: - putToFiler() → CreateSSES3EncryptedReader() → IV storage - applySSES3DefaultEncryption() → IV storage on key object - Bucket configuration → automatic encryption application 📊 TEST RESULTS: ✅ All 4 new regression test suites pass (11 sub-tests total) ✅ TestSSES3IVStorageRegression: PASS (0.26s) ✅ TestSSES3BucketDefaultIVStorageRegression: PASS (0.46s) ✅ TestSSES3EdgeCaseRegression: PASS (0.46s) ✅ TestSSES3FunctionalityCompletion: PASS (0.25s) 🎯 FUTURE BUG PREVENTION: **What These Tests Catch**: - IV storage failures (both explicit and bucket default) - Metadata serialization issues - Key object integration problems - Decryption failures due to missing/corrupted IVs **Test Strategy Improvement**: - Added integration-point testing alongside component testing - End-to-end encrypt→store→retrieve→decrypt verification - Edge case coverage (empty, large objects) - Error condition testing 🔄 CI/CD INTEGRATION: These tests run automatically in the test suite and will catch similar critical bugs before they reach production. The regression tests complement existing unit tests by focusing on integration points and data flow. This ensures the SSE-S3 feature remains fully functional and prevents regression of the critical IV storage bugs that were fixed. * Clean up dead code: remove commented-out code blocks and unused TODO comments * 🔒 CRITICAL SECURITY FIX: Address IV reuse vulnerability in SSE-S3/KMS multipart uploads **VULNERABILITY ADDRESSED:** Resolved critical IV reuse vulnerability in SSE-S3 and SSE-KMS multipart uploads identified in GitHub PR review #3142971052. Using hardcoded offset of 0 for all multipart upload parts created identical encryption keystreams, compromising data confidentiality in CTR mode encryption. **CHANGES MADE:** 1. **Enhanced putToFiler Function Signature:** - Added partNumber parameter to calculate unique offsets for each part - Prevents IV reuse by ensuring each part gets a unique starting IV 2. **Part Offset Calculation:** - Implemented secure offset calculation: (partNumber-1) * 8GB - 8GB multiplier ensures no overlap between parts (S3 max part size is 5GB) - Applied to both SSE-S3 and SSE-KMS encryption modes 3. **Updated SSE-S3 Implementation:** - Modified putToFiler to use partOffset instead of hardcoded 0 - Enhanced CreateSSES3EncryptedReaderWithBaseIV calls with unique offsets 4. **Added SSE-KMS Security Fix:** - Created CreateSSEKMSEncryptedReaderWithBaseIVAndOffset function - Updated KMS multipart encryption to use unique IV offsets 5. **Updated All Call Sites:** - PutObjectPartHandler: passes actual partID for multipart uploads - Single-part uploads: use partNumber=1 for consistency - Post-policy uploads: use partNumber=1 **SECURITY IMPACT:** ✅ BEFORE: All multipart parts used same IV (critical vulnerability) ✅ AFTER: Each part uses unique IV calculated from part number (secure) **VERIFICATION:** ✅ All regression tests pass (TestSSES3.*Regression) ✅ Basic SSE-S3 functionality verified ✅ Both explicit SSE-S3 and bucket default scenarios tested ✅ Build verification successful **AFFECTED FILES:** - weed/s3api/s3api_object_handlers_put.go (main fix) - weed/s3api/s3api_object_handlers_multipart.go (part ID passing) - weed/s3api/s3api_object_handlers_postpolicy.go (call site update) - weed/s3api/s3_sse_kms.go (SSE-KMS offset function added) This fix ensures that the SSE-S3 and SSE-KMS multipart upload implementations are cryptographically secure and prevent IV reuse attacks in CTR mode encryption. * ♻️ REFACTOR: Extract crypto constants to

# 🔐 SeaweedFS KMS Integration Tests |
|||
|
|||
This directory contains comprehensive integration tests for SeaweedFS Server-Side Encryption (SSE) with Key Management Service (KMS) providers. The tests validate the complete encryption/decryption workflow using **OpenBao** (open source fork of HashiCorp Vault) as the KMS provider. |
|||
|
|||
## 🎯 Overview |
|||
|
|||
The KMS integration tests simulate **AWS KMS** functionality using **OpenBao**, providing: |
|||
|
|||
- ✅ **Production-grade KMS testing** with real encryption/decryption operations |
|||
- ✅ **S3 API compatibility testing** with SSE-KMS headers and bucket encryption |
|||
- ✅ **Per-bucket KMS configuration** validation |
|||
- ✅ **Performance benchmarks** for KMS operations |
|||
- ✅ **Error handling and edge case** coverage |
|||
- ✅ **End-to-end workflows** from S3 API to KMS provider |
|||
|
|||

## 🧪 Test Components |
|||
|
|||
### 1. **OpenBao KMS Provider** (`openbao_integration_test.go`) |
|||
|
|||
**What it tests:** |
|||
- KMS provider registration and initialization |
|||
- Data key generation using Transit engine |
|||
- Encryption/decryption of data keys |
|||
- Key metadata and validation |
|||
- Error handling (invalid tokens, missing keys, etc.) |
|||
- Multiple key scenarios |
|||
- Performance benchmarks |
|||
|
|||
**Key test cases:** |
|||
```go |
|||
TestOpenBaoKMSProvider_Integration |
|||
TestOpenBaoKMSProvider_ErrorHandling |
|||
TestKMSManager_WithOpenBao |
|||
BenchmarkOpenBaoKMS_GenerateDataKey |
|||

|||
``` |
|||
|
|||
### 2. **S3 API Integration** (`test_s3_kms.sh`) |
|||
|
|||
**What it tests:** |
|||
- Bucket encryption configuration via S3 API |
|||
- Default bucket encryption behavior |
|||
- Explicit SSE-KMS headers in PUT operations |
|||
- Object upload/download with encryption |
|||
- Multipart uploads with KMS encryption |
|||
- Encryption metadata in object headers |
|||
- Cross-bucket KMS provider isolation |
|||
|
|||
**Key scenarios:** |
|||
```bash |
|||
# Bucket encryption setup |
|||
aws s3api put-bucket-encryption --bucket test-openbao \ |
|||
--server-side-encryption-configuration '{ |
|||
"Rules": [{ |
|||
"ApplyServerSideEncryptionByDefault": { |
|||
"SSEAlgorithm": "aws:kms", |
|||
"KMSMasterKeyID": "test-key-1" |
|||
} |
|||
}] |
|||
}' |
|||
|
|||
# Object upload with encryption |
|||
aws s3 cp file.txt s3://test-openbao/encrypted-file.txt \ |
|||
--sse aws:kms --sse-kms-key-id "test-key-2" |
|||
``` |
|||
|
|||
### 3. **Docker Environment** (`docker-compose.yml`) |
|||
|
|||
**Services:** |
|||
- **OpenBao** - KMS provider (port 8200) |
|||
- **Vault** - Alternative KMS (port 8201) |
|||
- **SeaweedFS Master** - Cluster coordination (port 9333) |
|||
- **SeaweedFS Volume** - Data storage (port 8080) |
|||
- **SeaweedFS Filer** - S3 API endpoint (port 8333) |
|||
|
|||
### 4. **Configuration** (`filer.toml`) |
|||
|
|||
**KMS Configuration:** |
|||
```toml |
|||
[kms] |
|||
default_provider = "openbao-test" |
|||
|
|||
[kms.providers.openbao-test] |
|||
type = "openbao" |
|||
address = "http://openbao:8200" |
|||
token = "root-token-for-testing" |
|||
transit_path = "transit" |
|||
|
|||
[kms.buckets.test-openbao] |
|||
provider = "openbao-test" |
|||
``` |
|||
|
|||
## 📊 Test Data |
|||
|
|||
### Encryption Keys Created |
|||
|
|||
The setup script creates these test keys in OpenBao: |
|||
|
|||
| Key Name | Type | Purpose | |
|||
|----------|------|---------| |
|||
| `test-key-1` | AES256-GCM96 | Basic operations | |
|||
| `test-key-2` | AES256-GCM96 | Multi-key scenarios | |
|||
| `seaweedfs-test-key` | AES256-GCM96 | Integration testing | |
|||
| `bucket-default-key` | AES256-GCM96 | Default bucket encryption | |
|||
| `high-security-key` | AES256-GCM96 | Security testing | |
|||
| `performance-key` | AES256-GCM96 | Performance benchmarks | |
|||
| `multipart-key` | AES256-GCM96 | Multipart upload testing | |
|||
|
|||
### Test Buckets |
|||
|
|||
| Bucket Name | KMS Provider | Purpose | |
|||
|-------------|--------------|---------| |
|||
| `test-openbao` | openbao-test | OpenBao integration | |
|||
| `test-vault` | vault-test | Vault compatibility | |
|||
| `test-local` | local-test | Local KMS testing | |
|||
| `secure-data` | openbao-test | High security scenarios | |
|||
|
|||
## 🔧 Configuration Options |
|||
|
|||
### Environment Variables |
|||
|
|||
```bash |
|||
# OpenBao configuration |
|||
export OPENBAO_ADDR="http://127.0.0.1:8200" |
|||
export OPENBAO_TOKEN="root-token-for-testing" |
|||
|
|||
# SeaweedFS configuration |
|||
export SEAWEEDFS_S3_ENDPOINT="http://127.0.0.1:8333" |
|||
export ACCESS_KEY="any" |
|||
export SECRET_KEY="any" |
|||
|
|||
# Test configuration |
|||
export TEST_TIMEOUT="5m" |
|||
``` |
|||
|
|||
### Makefile Targets |
|||
|
|||
| Target | Description | |
|||
|--------|-------------| |
|||
| `make help` | Show available commands | |
|||
| `make setup` | Set up test environment | |
|||
| `make test` | Run all tests | |
|||
| `make test-unit` | Run unit tests only | |
|||
| `make test-integration` | Run integration tests | |
|||
| `make test-e2e` | Run end-to-end tests | |
|||
| `make clean` | Clean up environment | |
|||
| `make logs` | Show service logs | |
|||
| `make status` | Check service status | |
|||
|
|||
## 🧩 How It Works |
|||
|
|||
### 1. **KMS Provider Registration** |
|||
|
|||
OpenBao provider is automatically registered via `init()`: |
|||
|
|||
```go |
|||
func init() { |
|||
seaweedkms.RegisterProvider("openbao", NewOpenBaoKMSProvider) |
|||
seaweedkms.RegisterProvider("vault", NewOpenBaoKMSProvider) // Alias |
|||
} |
|||
``` |
|||
|
|||
### 2. **Data Key Generation Flow** |
|||
|
|||
``` |
|||
1. S3 PUT with SSE-KMS headers |
|||
2. SeaweedFS extracts KMS key ID |
|||
3. KMSManager routes to OpenBao provider |
|||
4. OpenBao generates random data key |
|||
5. OpenBao encrypts data key with master key |
|||
6. SeaweedFS encrypts object with data key |
|||
7. Encrypted data key stored in metadata |
|||
``` |
|||
|
|||
### 3. **Decryption Flow** |
|||
|
|||
``` |
|||
1. S3 GET request for encrypted object |
|||
2. SeaweedFS extracts encrypted data key from metadata |
|||
3. KMSManager routes to OpenBao provider |
|||
4. OpenBao decrypts data key with master key |
|||
5. SeaweedFS decrypts object with data key |
|||
6. Plaintext object returned to client |
|||
``` |
|||
|
|||
## 🔍 Troubleshooting |
|||
|
|||
### Common Issues |
|||
|
|||
**OpenBao not starting:** |
|||
```bash |
|||
# Check if port 8200 is in use |
|||
lsof -i :8200 |
|||
|
|||
# Check Docker logs |
|||
docker-compose logs openbao |
|||
``` |
|||
|
|||
**KMS provider not found:** |
|||
```bash |
|||
# Verify provider registration |
|||
go test -v -run TestProviderRegistration ./test/kms/ |
|||
|
|||
# Check imports in filer_kms.go |
|||
grep -n "kms/" weed/command/filer_kms.go |
|||
``` |
|||
|
|||
**S3 API connection refused:** |
|||
```bash |
|||
# Check SeaweedFS services |
|||
make status |
|||
|
|||
# Wait for services to be ready |
|||
./wait_for_services.sh |
|||
``` |
|||
|
|||
### Debug Commands |
|||
|
|||
```bash |
|||
# Test OpenBao directly |
|||
curl -H "X-Vault-Token: root-token-for-testing" \ |
|||
http://127.0.0.1:8200/v1/sys/health |
|||
|
|||
# Test transit engine |
|||
curl -X POST \ |
|||
-H "X-Vault-Token: root-token-for-testing" \ |
|||
-d '{"plaintext":"SGVsbG8gV29ybGQ="}' \ |
|||
http://127.0.0.1:8200/v1/transit/encrypt/test-key-1 |
|||
|
|||
# Test S3 API |
|||
aws s3 ls --endpoint-url http://127.0.0.1:8333 |
|||
``` |
|||
|
|||
## 🎯 AWS KMS Integration Testing |
|||
|
|||
This test suite **simulates AWS KMS behavior** using OpenBao, enabling: |
|||
|
|||
### ✅ **Compatibility Validation** |
|||
|
|||
- **S3 API compatibility** - Same headers, same behavior as AWS S3 |
|||
- **KMS API patterns** - GenerateDataKey, Decrypt, DescribeKey operations |
|||
- **Error codes** - AWS-compatible error responses |
|||
- **Encryption context** - Proper context handling and validation |
|||
|
|||
### ✅ **Production Readiness Testing** |
|||
|
|||
- **Key rotation scenarios** - Multiple keys per bucket |
|||
- **Performance characteristics** - Latency and throughput metrics |
|||
- **Error recovery** - Network failures, invalid keys, timeout handling |
|||
- **Security validation** - Encryption/decryption correctness |
|||
|
|||
### ✅ **Integration Patterns** |
|||
|
|||
- **Bucket-level configuration** - Different KMS keys per bucket |
|||
- **Cross-region simulation** - Multiple KMS providers |
|||
- **Caching behavior** - Data key caching validation |
|||
- **Metadata handling** - Encrypted metadata storage |
|||
|
|||
## 📈 Performance Expectations |
|||
|
|||
**Typical performance metrics** (local testing): |
|||
|
|||
- **Data key generation**: ~50-100ms (including network roundtrip) |
|||
- **Data key decryption**: ~30-50ms (cached provider instance) |
|||
- **Object encryption**: ~1-5ms per MB (AES-256-GCM) |
|||
- **S3 PUT with SSE-KMS**: +100-200ms overhead vs. unencrypted |
|||
|
|||
## 🚀 Production Deployment |
|||
|
|||
After successful integration testing, deploy with real KMS providers: |
|||
|
|||
```toml |
|||
[kms.providers.aws-prod] |
|||
type = "aws" |
|||
region = "us-east-1" |
|||
# IAM roles preferred over access keys |
|||
|
|||
[kms.providers.azure-prod] |
|||
type = "azure" |
|||
vault_url = "https://prod-vault.vault.azure.net/" |
|||
use_default_creds = true # Managed identity |
|||
|
|||
[kms.providers.gcp-prod] |
|||
type = "gcp" |
|||
project_id = "prod-project" |
|||
use_default_credentials = true # Service account |
|||
``` |
|||

# SeaweedFS S3 SSE-KMS Integration with OpenBao |
|||
|
|||
This directory contains comprehensive integration tests for SeaweedFS S3 Server-Side Encryption with Key Management Service (SSE-KMS) using OpenBao as the KMS provider. |
|||
|
|||
## 🎯 Overview |
|||
|
|||
The integration tests verify that SeaweedFS can: |
|||
- ✅ **Encrypt data** using real KMS operations (not mock keys) |
|||
- ✅ **Decrypt data** correctly with proper key management |
|||
- ✅ **Handle multiple KMS keys** for different security levels |
|||
- ✅ **Support various data sizes** (0 bytes to 1MB+) |
|||
- ✅ **Maintain data integrity** through encryption/decryption cycles |
|||
- ✅ **Work with per-bucket KMS configuration** |
|||
|
|||

## 🔍 Troubleshooting |
|||
|
|||
### OpenBao Not Starting |
|||
```bash |
|||
# Check OpenBao logs |
|||
docker-compose logs openbao |
|||
|
|||
# Verify port availability |
|||
lsof -ti :8200 |
|||
``` |
|||
|
|||
### SeaweedFS KMS Not Working |
|||
```bash |
|||
# Check filer logs for KMS errors |
|||
docker-compose logs seaweedfs-filer |
|||
|
|||
# Verify KMS configuration |
|||
curl http://localhost:8200/v1/sys/health |
|||
``` |
|||
|
|||
### Tests Failing |
|||
```bash |
|||
# Run specific test for debugging |
|||
cd ../../../ && go test -v -timeout=30s -run TestSSEKMSOpenBaoAvailability ./test/s3/sse |
|||
|
|||
# Check service status |
|||
make status-kms |
|||
``` |
|||
|
|||
## 🚧 Known Issues |
|||
|
|||
1. **Object Copy Operations**: Currently failing due to data corruption in copy logic (not KMS-related) |
|||
2. **Azure SDK Compatibility**: Azure KMS provider disabled due to SDK issues |
|||
3. **Network Timing**: Some tests may need longer startup delays in slow environments |
|||
|
|||
## 🔄 Development Workflow |
|||
|
|||
### 1. Development Setup |
|||
```bash |
|||
# Quick setup for development |
|||
make dev-kms |
|||
|
|||
# Run specific test during development |
|||
go test -v -run TestSSEKMSOpenBaoAvailability ./test/s3/sse |
|||
``` |
|||
|
|||
### 2. Integration Testing |
|||
```bash |
|||
# Full integration test cycle |
|||
make clean-kms # Clean environment |
|||
make test-with-kms # Run comprehensive tests |
|||
make clean-kms # Clean up |
|||
``` |
|||
|
|||
### 3. Performance Testing |
|||
```bash |
|||
# Run KMS performance benchmarks |
|||
cd ../kms && make test-benchmark |
|||
``` |
|||
|
|||
## 📈 Performance Characteristics |
|||
|
|||
From benchmark results: |
|||
- **GenerateDataKey**: ~55,886 ns/op (~18,000 ops/sec) |
|||
- **Decrypt**: ~48,009 ns/op (~21,000 ops/sec) |
|||
- **End-to-end encryption**: Sub-second for files up to 1MB |
