Author	SHA1	Message	Date
Chris Lu	5472061231	Fix: Populate Claims from STS session RequestContext for policy variable substitution (#8082) * 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	3 days ago
Chris Lu	51735e667c	Fix S3 conditional writes with versioning (Issue #8073) (#8080) * Fix S3 conditional writes with versioning (Issue #8073) Refactors conditional header checks to properly resolve the latest object version when versioning is enabled. This prevents incorrect validation against non-versioned root objects. * Add integration test for S3 conditional writes with versioning (Issue #8073) * Refactor: Propagate internal errors in conditional header checks - Make resolveObjectEntry return errors from isVersioningConfigured - Update checkConditionalHeaders checks to return 500 on internal resolve errors * Refactor: Stricter error handling and test assertions - Propagate internal errors in checkConditionalHeaders*WithGetter functions - Enforce strict 412 PreconditionFailed check in integration test * Perf: Add early return for conditional headers + safety improvements - Add fast path to skip resolveObjectEntry when no conditional headers present - Avoids expensive getLatestObjectVersion retries in common case - Add nil checks before dereferencing pointers in integration test - Fix grammar in test comments - Remove duplicate comment in resolveObjectEntry * Refactor: Use errors.Is for robust ErrNotFound checking - Update checkConditionalHeaders* to use errors.Is(err, filer_pb.ErrNotFound) - Update resolveObjectEntry to use errors.Is for wrapped error compatibility - Remove duplicate comment lines in s3api handlers * Perf: Optimize resolveObjectEntry for conditional checks - Refactor getLatestObjectVersion to doGetLatestObjectVersion supporting variable retries - Use 1-retry path in resolveObjectEntry to avoid exponential backoff latency * Test: Enhance integration test with content verification - Verify actual object content equals expected content after successful conditional write - Add missing io and errors imports to test file * Refactor: Final refinements based on feedback - Optimize header validation by passing parsed headers to avoid redundant parsing - Simplify integration test assertions using require.Error and assert.True - Fix build errors in s3api handler and test imports * Test: Use smithy.APIError for robust error code checking - Replace string-based error checking with structured API error - Add smithy-go import for AWS SDK v2 error handling * Test: Use types.PreconditionFailed and handle io.ReadAll error - Replace smithy.APIError with more specific types.PreconditionFailed - Add proper error handling for io.ReadAll in content verification * Refactor: Use combined error checking and add nil guards - Use smithy.APIError with ErrorCode() for robust error checking - Add nil guards for entry.Attributes before accessing Mtime - Prevents potential panics when Attributes is uninitialized	3 days ago
粒粒橙	52882aed70	fix(s3api): missing `Vary: Origin` header on non-CORS and `OPTIONS` requests (#8072) * fix: Refactor CORS middleware to consistently apply the `Vary: Origin` header when a configuration exists and streamline request processing logic. * fix: Add Vary: Origin header to CORS OPTIONS responses and refactor request handling for clarity and correctness. * fix: update CORS middleware tests to correctly parse and check for 'Origin' in Vary header. * refactor: extract `hasVaryOrigin` helper function to simplify Vary header checks in tests. * test: Remove `Vary: Origin` header from CORS test expectations. * refactor: consolidate CORS request handling into a new `processCORS` method using a `next` callback.	3 days ago

Chris Lu	7d788ae73c	Fix: S3 CORS headers missing for non-existent buckets (#8078) Fix S3 CORS for non-existent buckets Enable fallback to global CORS configuration when a bucket is not found (s3err.ErrNoSuchBucket). This ensures consistent CORS behavior and prevents information disclosure.	3 days ago
Chris Lu	3d1f710485	remove the .versions directory when all versions are deleted	4 days ago
Chris Lu	f6a2ef11ff	Fix CORS headers not applied to non-existent bucket responses (#8070) Fixes #8065 Problem: - CORS headers were only applied after checking bucket existence - Non-existent buckets returned responses without CORS headers - This caused CORS preflight failures and information disclosure vulnerability - Unauthenticated users could infer bucket existence from CORS header presence Solution: - Moved CORS evaluation before bucket existence check in middleware - CORS headers now applied consistently regardless of bucket existence - Preflight requests succeed for non-existent buckets (matching AWS S3) - Actual requests still return NoSuchBucket error but with CORS headers Changes: - Modified Handler() and HandleOptionsRequest() in middleware.go - Added comprehensive test suite for non-existent bucket scenarios - All 39 tests passing (31 existing + 8 new) Security Impact: - Prevents information disclosure about bucket existence - Bucket existence cannot be inferred from CORS header presence/absence AWS S3 Compatibility: - Improved compatibility with AWS S3 CORS behavior - Preflight requests now succeed for non-existent buckets	4 days ago
Chris Lu	bc8a077561	Fix: Propagate OIDC claims for dynamic IAM policies (#8060) Fix: Propagate OIDC claims to IAM identity for dynamic policy variables Fixes #8037.

Chris Lu	ee3813787e	feat(s3api): Implement S3 Policy Variables (#8039) * feat: Add AWS IAM Policy Variables support to S3 API Implements policy variables for dynamic access control in bucket policies. Supported variables: - aws:username - Extracted from principal ARN - aws:userid - User identifier (same as username in SeaweedFS) - aws:principaltype - IAMUser, IAMRole, or AssumedRole - jwt:* - Any JWT claim (e.g., jwt:preferred_username, jwt:sub) Key changes: - Added PolicyVariableRegex to detect ${...} patterns - Extended CompiledStatement with DynamicResourcePatterns, DynamicPrincipalPatterns, DynamicActionPatterns - Added Claims field to PolicyEvaluationArgs for JWT claim access - Implemented SubstituteVariables() for variable replacement from context and JWT claims - Implemented extractPrincipalVariables() for ARN parsing - Updated EvaluateConditions() to support variable substitution - Comprehensive unit and integration tests Resolves #8037 * feat: Add LDAP and PrincipalAccount variable support Completes future enhancements for policy variables: - Added ldap:* variable support for LDAP claims - ldap:username - LDAP username from claims - ldap:dn - LDAP distinguished name from claims - ldap:* - Any LDAP claim - Added aws:PrincipalAccount extraction from ARN - Extracts account ID from principal ARN - Available as ${aws:PrincipalAccount} in policies Updated SubstituteVariables() to check LDAP claims Updated extractPrincipalVariables() to extract account ID Added comprehensive tests for new variables * feat(s3api): implement IAM policy variables core logic and optimization * feat(s3api): integrate policy variables with S3 authentication and handlers * test(s3api): add integration tests for policy variables * cleanup: remove unused policy conversion files * Add S3 policy variables integration tests and path support - Add comprehensive integration tests for policy variables - Test username isolation, JWT claims, LDAP claims - Add support for IAM paths in principal ARN parsing - Add tests for principals with paths * Fix IAM Role principal variable extraction IAM Roles should not have aws:userid or aws:PrincipalAccount according to AWS behavior. Only IAM Users and Assumed Roles should have these variables. Fixes TestExtractPrincipalVariables test failures. * Security fixes and bug fixes for S3 policy variables SECURITY FIXES: - Prevent X-SeaweedFS-Principal header spoofing by clearing internal headers at start of authentication (auth_credentials.go) - Restrict policy variable substitution to safe allowlist to prevent client header injection (iam/policy/policy_engine.go) - Add core policy validation before storing bucket policies BUG FIXES: - Remove unused sid variable in evaluateStatement - Fix LDAP claim lookup to check both prefixed and unprefixed keys - Add ValidatePolicy call in PutBucketPolicyHandler These fixes prevent privilege escalation via header injection and ensure only validated identity claims are used in policy evaluation. * Additional security fixes and code cleanup SECURITY FIXES: - Fixed X-Forwarded-For spoofing by only trusting proxy headers from private/localhost IPs (s3_iam_middleware.go) - Changed context key from "sourceIP" to "aws:SourceIp" for proper policy variable substitution CODE IMPROVEMENTS: - Kept aws:PrincipalAccount for IAM Roles to support condition evaluations - Removed redundant STS principaltype override - Removed unused service variable - Cleaned up commented-out debug logging statements - Updated tests to reflect new IAM Role behavior These changes prevent IP spoofing attacks and ensure policy variables work correctly with the safe allowlist. * Add security documentation for ParseJWTToken Added comprehensive security comments explaining that ParseJWTToken is safe despite parsing without verification because: - It's only used for routing to the correct verification method - All code paths perform cryptographic verification before trusting claims - OIDC tokens: validated via validateExternalOIDCToken - STS tokens: validated via ValidateSessionToken Enhanced function documentation with clear security warnings about proper usage to prevent future misuse. * Fix IP condition evaluation to use aws:SourceIp key Fixed evaluateIPCondition in IAM policy engine to use "aws:SourceIp" instead of "sourceIP" to match the updated extractRequestContext. This fixes the failing IP-restricted role test where IP-based policy conditions were not being evaluated correctly. Updated all test cases to use the correct "aws:SourceIp" key. * Address code review feedback: optimize and clarify PERFORMANCE IMPROVEMENT: - Optimized expandPolicyVariables to use regexp.ReplaceAllStringFunc for single-pass variable substitution instead of iterating through all safe variables. This improves performance from O(n*m) to O(m) where n is the number of safe variables and m is the pattern length. CODE CLARITY: - Added detailed comment explaining LDAP claim fallback mechanism (checks both prefixed and unprefixed keys for compatibility) - Enhanced TODO comment for trusted proxy configuration with rationale and recommendations for supporting cloud load balancers, CDNs, and complex network topologies All tests passing. * Address Copilot code review feedback BUG FIXES: - Fixed type switch for int/int32/int64 - separated into individual cases since interface type switches only match the first type in multi-type cases - Fixed grammatically incorrect error message in types.go CODE QUALITY: - Removed duplicate Resource/NotResource validation (already in ValidateStatement) - Added comprehensive comment explaining isEnabled() logic and security implications - Improved trusted proxy NOTE comment to be more concise while noting limitations All tests passing. * Fix test failures after extractSourceIP security changes Updated tests to work with the security fix that only trusts X-Forwarded-For/X-Real-IP headers from private IP addresses: - Set RemoteAddr to 127.0.0.1 in tests to simulate trusted proxy - Changed context key from "sourceIP" to "aws:SourceIp" - Added test case for untrusted proxy (public RemoteAddr) - Removed invalid ValidateStatement call (validation happens in ValidatePolicy) All tests now passing. * Address remaining Gemini code review feedback CODE SAFETY: - Deep clone Action field in CompileStatement to prevent potential data races if the original policy document is modified after compilation TEST CLEANUP: - Remove debug logging (fmt.Fprintf) from engine_notresource_test.go - Remove unused imports in engine_notresource_test.go All tests passing. * Fix insecure JWT parsing in IAM auth flow SECURITY FIX: - Renamed ParseJWTToken to ParseUnverifiedJWTToken with explicit security warnings. - Refactored AuthenticateJWT to use the trusted SessionInfo returned by ValidateSessionToken instead of relying on unverified claims from the initial parse. - Refactored ValidatePresignedURLWithIAM to reuse the robust AuthenticateJWT logic, removing duplicated and insecure manual token parsing. This ensures all identity information (Role, Principal, Subject) used for authorization decisions is derived solely from cryptographically verified tokens. * Security: Fix insecure JWT claim extraction in policy engine - Refactored EvaluatePolicy to accept trusted claims from verified Identity instead of parsing unverified tokens - Updated AuthenticateJWT to populate Claims in IAMIdentity from verified sources (SessionInfo/ExternalIdentity) - Updated s3api_server and handlers to pass claims correctly - Improved isPrivateIP to support IPv6 loopback, link-local, and ULA - Fixed flaky distributed_session_consistency test with retry logic * fix(iam): populate Subject in STSSessionInfo to ensure correct identity propagation This fixes the TestS3IAMAuthentication/valid_jwt_token_authentication failure by ensuring the session subject (sub) is correctly mapped to the internal SessionInfo struct, allowing bucket ownership validation to succeed. * Optimized isPrivateIP * Create s3-policy-tests.yml * fix tests * fix tests * tests(s3/iam): simplify policy to resource-based \ (step 1) * tests(s3/iam): add explicit Deny NotResource for isolation (step 2) * fixes * policy: skip resource matching for STS trust policies to allow AssumeRole evaluation * refactor: remove debug logging and hoist policy variables for performance * test: fix TestS3IAMBucketPolicyIntegration cleanup to handle per-subtest object lifecycle * test: fix bucket name generation to comply with S3 63-char limit * test: skip TestS3IAMPolicyEnforcement until role setup is implemented * test: use weed mini for simpler test server deployment Replace 'weed server' with 'weed mini' for IAM tests to avoid port binding issues and simplify the all-in-one server deployment. This improves test reliability and execution time. * security: prevent allocation overflow in policy evaluation Add maxPoliciesForEvaluation constant to cap the number of policies evaluated in a single request. This prevents potential integer overflow when allocating slices for policy lists that may be influenced by untrusted input. Changes: - Add const maxPoliciesForEvaluation = 1024 to set an upper bound - Validate len(policies) < maxPoliciesForEvaluation before appending bucket policy - Use append() instead of make([]string, len+1) to avoid arithmetic overflow - Apply fix to both IsActionAllowed policy evaluation paths	1 week ago

Chris Lu	06391701ed	Add AssumeRole and AssumeRoleWithLDAPIdentity STS actions (#8003) * test: add integration tests for AssumeRole and AssumeRoleWithLDAPIdentity STS actions - Add s3_sts_assume_role_test.go with comprehensive tests for AssumeRole: * Parameter validation (missing RoleArn, RoleSessionName, invalid duration) * AWS SigV4 authentication with valid/invalid credentials * Temporary credential generation and usage - Add s3_sts_ldap_test.go with tests for AssumeRoleWithLDAPIdentity: * Parameter validation (missing LDAP credentials, RoleArn) * LDAP authentication scenarios (valid/invalid credentials) * Integration with LDAP server (when configured) - Update Makefile with new test targets: * test-sts: run all STS tests * test-sts-assume-role: run AssumeRole tests only * test-sts-ldap: run LDAP STS tests only * test-sts-suite: run tests with full service lifecycle - Enhance setup_all_tests.sh: * Add OpenLDAP container setup for LDAP testing * Create test LDAP users (testuser, ldapadmin) * Set LDAP environment variables for tests * Update cleanup to remove LDAP container - Fix setup_keycloak.sh: * Enable verbose error logging for realm creation * Improve error diagnostics Tests use fail-fast approach (t.Fatal) when server not configured, ensuring clear feedback when infrastructure is missing. * feat: implement AssumeRole and AssumeRoleWithLDAPIdentity STS actions Implement two new STS actions to match MinIO's STS feature set: **AssumeRole Implementation:** - Add handleAssumeRole with full AWS SigV4 authentication - Integrate with existing IAM infrastructure via verifyV4Signature - Validate required parameters (RoleArn, RoleSessionName) - Validate DurationSeconds (900-43200 seconds range) - Generate temporary credentials with expiration - Return AWS-compatible XML response **AssumeRoleWithLDAPIdentity Implementation:** - Add handleAssumeRoleWithLDAPIdentity handler (stub) - Validate LDAP-specific parameters (LDAPUsername, LDAPPassword) - Validate common STS parameters (RoleArn, RoleSessionName, DurationSeconds) - Return proper error messages for missing LDAP provider - Ready for LDAP provider integration **Routing Fixes:** - Add explicit routes for AssumeRole and AssumeRoleWithLDAPIdentity - Prevent IAM handler from intercepting authenticated STS requests - Ensure proper request routing priority **Handler Infrastructure:** - Add IAM field to STSHandlers for SigV4 verification - Update NewSTSHandlers to accept IAM reference - Add STS-specific error codes and response types - Implement writeSTSErrorResponse for AWS-compatible errors The AssumeRole action is fully functional and tested. AssumeRoleWithLDAPIdentity requires LDAP provider implementation. * fix: update IAM matcher to exclude STS actions from interception Update the IAM handler matcher to check for STS actions (AssumeRole, AssumeRoleWithWebIdentity, AssumeRoleWithLDAPIdentity) and exclude them from IAM handler processing. This allows STS requests to be handled by the STS fallback handler even when they include AWS SigV4 authentication. The matcher now parses the form data to check the Action parameter and returns false for STS actions, ensuring they are routed to the correct handler. Note: This is a work-in-progress fix. Tests are still showing some routing issues that need further investigation. * fix: address PR review security issues for STS handlers This commit addresses all critical security issues from PR review: Security Fixes: - Use crypto/rand for cryptographically secure credential generation instead of time.Now().UnixNano() (fixes predictable credentials) - Add sts:AssumeRole permission check via VerifyActionPermission to prevent unauthorized role assumption - Generate proper session tokens using crypto/rand instead of placeholder strings Code Quality Improvements: - Refactor DurationSeconds parsing into reusable parseDurationSeconds() helper function used by all three STS handlers - Create generateSecureCredentials() helper for consistent and secure temporary credential generation - Fix iamMatcher to check query string as fallback when Action not found in form data LDAP Provider Implementation: - Add go-ldap/ldap/v3 dependency - Create LDAPProvider implementing IdentityProvider interface with full LDAP authentication support (connect, bind, search, groups) - Update ProviderFactory to create real LDAP providers - Wire LDAP provider into AssumeRoleWithLDAPIdentity handler Test Infrastructure: - Add LDAP user creation verification step in setup_all_tests.sh * fix: address PR feedback (Round 2) - config validation & provider improvements - Implement `validateLDAPConfig` in `ProviderFactory` - Improve `LDAPProvider.Initialize`: - Support `connectionTimeout` parsing (string/int/float) from config map - Warn if `BindDN` is present but `BindPassword` is empty - Improve `LDAPProvider.GetUserInfo`: - Add fallback to `searchUserGroups` if `memberOf` returns no groups (consistent with Authenticate) * fix: address PR feedback (Round 3) - LDAP connection improvements & build fix - Improve `LDAPProvider` connection handling: - Use `net.Dialer` with configured timeout for connection establishment - Enforce TLS 1.2+ (`MinVersion: tls.VersionTLS12`) for both LDAPS and StartTLS - Fix build error in `s3api_sts.go` (format verb for ErrorCode) * fix: address PR feedback (Round 4) - LDAP hardening, Authz check & Routing fix - LDAP Provider Hardening: - Prevent re-initialization - Enforce single user match in `GetUserInfo` (was explicit only in Authenticate) - Ensure connection closure if StartTLS fails - STS Handlers: - Add robust provider detection using type assertion - **Security**: Implement authorization check (`VerifyActionPermission`) after LDAP authentication - Routing: - Update tests to reflect that STS actions are handled by STS handler, not generic IAM * fix: address PR feedback (Round 5) - JWT tokens, ARN formatting, PrincipalArn CRITICAL FIXES: - Replace standalone credential generation with STS service JWT tokens - handleAssumeRole now generates proper JWT session tokens - handleAssumeRoleWithLDAPIdentity now generates proper JWT session tokens - Session tokens can be validated across distributed instances - Fix ARN formatting in responses - Extract role name from ARN using utils.ExtractRoleNameFromArn() - Prevents malformed ARNs like "arn:aws:sts::assumed-role/arn:aws:iam::..." - Add configurable AccountId for federated users - Add AccountId field to STSConfig (defaults to "111122223333") - PrincipalArn now uses configured account ID instead of hardcoded "aws" - Enables proper trust policy validation IMPROVEMENTS: - Sanitize LDAP authentication error messages (don't leak internal details) - Remove duplicate comment in provider detection - Add utils import for ARN parsing utilities * feat: implement LDAP connection pooling to prevent resource exhaustion PERFORMANCE IMPROVEMENT: - Add connection pool to LDAPProvider (default size: 10 connections) - Reuse LDAP connections across authentication requests - Prevent file descriptor exhaustion under high load IMPLEMENTATION: - connectionPool struct with channel-based connection management - getConnection(): retrieves from pool or creates new connection - returnConnection(): returns healthy connections to pool - createConnection(): establishes new LDAP connection with TLS support - Close(): cleanup method to close all pooled connections - Connection health checking (IsClosing()) before reuse BENEFITS: - Reduced connection overhead (no TCP handshake per request) - Better resource utilization under load - Prevents "too many open files" errors - Non-blocking pool operations (creates new conn if pool empty) * fix: correct TokenGenerator access in STS handlers CRITICAL FIX: - Make TokenGenerator public in STSService (was private tokenGenerator) - Update all references from Config.TokenGenerator to TokenGenerator - Remove TokenGenerator from STSConfig (it belongs in STSService) This fixes the "NotImplemented" errors in distributed and Keycloak tests. The issue was that Round 5 changes tried to access Config.TokenGenerator which didn't exist - TokenGenerator is a field in STSService, not STSConfig. The TokenGenerator is properly initialized in STSService.Initialize() and is now accessible for JWT token generation in AssumeRole handlers. * fix: update tests to use public TokenGenerator field Following the change to make TokenGenerator public in STSService, this commit updates the test files to reference the correct public field name. This resolves compilation errors in the IAM STS test suite. * fix: update distributed tests to use valid Keycloak users Updated s3_iam_distributed_test.go to use 'admin-user' and 'read-user' which exist in the standard Keycloak setup provided by setup_keycloak.sh. This resolves 'unknown test user' errors in distributed integration tests. * fix: ensure iam_config.json exists in setup target for CI The GitHub Actions workflow calls 'make setup' which was not creating iam_config.json, causing the server to start without IAM integration enabled (iamIntegration = nil), resulting in NotImplemented errors. Now 'make setup' copies iam_config.local.json to iam_config.json if it doesn't exist, ensuring IAM is properly configured in CI. * fix(iam/ldap): fix connection pool race and rebind corruption - Add atomic 'closed' flag to connection pool to prevent racing on Close() - Rebind authenticated user connections back to service account before returning to pool - Close connections on error instead of returning potentially corrupted state to pool * fix(iam/ldap): populate standard TokenClaims fields in ValidateToken - Set Subject, Issuer, Audience, IssuedAt, and ExpiresAt to satisfy the interface - Use time.Time for timestamps as required by TokenClaims struct - Default to 1 hour TTL for LDAP tokens * fix(s3api): include account ID in STS AssumedRoleUser ARN - Consistent with AWS, include the account ID in the assumed-role ARN - Use the configured account ID from STS service if available, otherwise default to '111122223333' - Apply to both AssumeRole and AssumeRoleWithLDAPIdentity handlers - Also update .gitignore to ignore IAM test environment files * refactor(s3api): extract shared STS credential generation logic - Move common logic for session claims and credential generation to prepareSTSCredentials - Update handleAssumeRole and handleAssumeRoleWithLDAPIdentity to use the helper - Remove stale comments referencing outdated line numbers * feat(iam/ldap): make pool size configurable and add audience support - Add PoolSize to LDAPConfig (default 10) - Add Audience to LDAPConfig to align with OIDC validation - Update initialization and ValidateToken to use new fields * update tests * debug * chore(iam): cleanup debug prints and fix test config port * refactor(iam): use mapstructure for LDAP config parsing * feat(sts): implement strict trust policy validation for AssumeRole * test(iam): refactor STS tests to use AWS SDK signer * test(s3api): implement ValidateTrustPolicyForPrincipal in MockIAMIntegration * fix(s3api): ensure IAM matcher checks query string on ParseForm error * fix(sts): use crypto/rand for secure credentials and extract constants * fix(iam): fix ldap connection leaks and add insecure warning * chore(iam): improved error wrapping and test parameterization * feat(sts): add support for LDAPProviderName parameter * Update weed/iam/ldap/ldap_provider.go Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update weed/s3api/s3api_sts.go Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * fix(sts): use STSErrSTSNotReady when LDAP provider is missing * fix(sts): encapsulate TokenGenerator in STSService and add getter --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>	2 weeks ago
Chris Lu	1ea6b0c0d9	cleanup: deduplicate environment variable credential loading Previously, `weed mini` logic duplicated the credential loading process by creating a temporary IAM config file from environment variables. `auth_credentials.go` also had fallback logic to load these variables. This change: 1. Updates `auth_credentials.go` to *always* check for and merge AWS environment variable credentials (`AWS_ACCESS_KEY_ID`, etc.) into the identity list. This ensures they are available regardless of whether other configurations (static file or filer) are loaded. 2. Removes the redundant file creation logic from `weed/command/mini.go`. 3. Updates `weed mini` user messages to accurately reflect that credentials are loaded from environment variables in-memory. This results in a cleaner implementation where `weed/s3api` manages all credential loading logic, and `weed mini` simply relies on it.	2 weeks ago
Chris Lu	7f1182472a	fix: enable dual loading of static and dynamic IAM configuration Refactored `NewIdentityAccessManagementWithStore` to remove mutual exclusivity between static (file-based) and dynamic (filer-based) configuration loading. Previously, if a static config configuration was present (including the legacy `IamConfig` option used by `weed mini`), it prevented loading users from the filer. Now, the system loads the static configuration first (if present), and then *always* attempts to merge in the dynamic configuration from the filer. This ensures that: 1. Static users (e.g. from `weed mini` env vars or `-s3.config`) are loaded and protected. 2. Dynamic users (e.g. created via Admin UI and stored in Filer) are also loaded and available.	2 weeks ago
Chris Lu	451b897d56	fix: support loading static config from IamConfig option for mini mode `weed mini` sets the `-s3.iam.config` flag instead of `-s3.config`, which populates `S3ApiServerOption.IamConfig`. Previously, `NewIdentityAccessManagementWithStore` only checked `option.Config`. This caused `weed mini` generated credentials (written to a temp file passed via IamConfig) to be ignored, breaking S3 access in mini mode even when environment variables were provided. This change ensures we try to load the configuration from `IamConfig` if `Config` is empty, restoring functionality for `weed mini`.	2 weeks ago
Chris Lu	48ded6b965	fix: allow environment variable fallback when filer config is empty Fixed regression where AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables were not being loaded as fallback credentials. The issue was that configLoaded was set to true when filer call succeeded, even if it returned an empty configuration. This blocked the environment variable fallback logic. Now only set configLoaded = true when we actually have loaded identities, allowing env vars to work correctly in mini mode and other scenarios where filer config is empty.	2 weeks ago
Chris Lu	4e835a1d81	fix(s3api): ensure S3 configuration persistence and refactor authorization tests (#7989) * fix(s3api): ensure static config file takes precedence over dynamic updates When a static S3 configuration file is provided, avoid overwriting the configuration from dynamic filer updates. This ensures the documented "Highest Priority" for the configuration file is respected. * refactor(s3api): implement merge-based static config with immutable identities Static identities from config file are now immutable and protected from dynamic updates. Dynamic identities (from admin panel) can be added and updated without affecting static entries. - Track identity names loaded from static config file - Implement merge logic that preserves static identities - Allow dynamic identities to be added or updated - Remove blanket block on config file updates * fix: address PR review comments for static config merge logic Critical Bugs: - Fix existingIdx always-false condition causing duplicate identities - Fix race condition in static config initialization (move useStaticConfig inside mutex) Security & Robustness: - Add nil identity check in VerifyActionPermission to fail closed - Mask access keys in STS validation logs to avoid exposing credentials - Add nil guard for s3a.iam in subscription handler Test Improvements: - Add authCalled tracking to MockIAMIntegration for explicit verification - Lower log level for static config messages to reduce noise * fix: prevent duplicates and race conditions in merge logic Data Integrity: - Prevent service account credential duplicates on repeated merges - Clean up stale accessKeyIdent entries when replacing identities - Check existing credentials before appending Concurrency Safety: - Add synchronization to IsStaticConfig method Test Improvements: - Add mux route vars for proper GetBucketAndObject extraction - Add STS session token header to trigger correct auth path	2 weeks ago
Chris Lu	abfa64456b	Fix STS authorization in streaming/chunked uploads (#7988) * Fix STS authorization in streaming/chunked uploads During streaming/chunked uploads (SigV4 streaming), authorization happens twice: 1. Initial authorization in authRequestWithAuthType() - works correctly 2. Second authorization in verifyV4Signature() - was failing for STS The issue was that verifyV4Signature() only used identity.canDo() for permission checks, which always denies STS identities (they have empty Actions). This bypassed IAM authorization completely. This commit makes verifyV4Signature() IAM-aware by adding the same fallback logic used in authRequestWithAuthType(): - Traditional identities (with Actions) use legacy canDo() check - STS/JWT identities (empty Actions) fall back to IAM authorization Fixes: https://github.com/seaweedfs/seaweedfs/pull/7986#issuecomment-3723196038 * Add comprehensive unit tests for STS authorization in streaming uploads Created test suite to verify that verifyV4Signature properly handles STS identities by falling back to IAM authorization when shouldCheckPermissions is true. Tests cover: - STS identities with IAM integration (allow and deny cases) - STS identities without IAM integration (should deny) - Traditional identities with Actions (canDo check) - Permission check bypass when shouldCheckPermissions=false - Specific streaming upload scenario from bug report - Action determination based on HTTP method All tests pass successfully. * Refactor authorization logic to avoid duplication Centralized the authorization logic into IdentityAccessManagement.VerifyActionPermission. Updated auth_signature_v4.go and auth_credentials.go to use this new helper. Updated tests to clarify that they mirror the centralized logic. * Refactor tests to use VerifyActionPermission directly Introduced IAMIntegration interface to facilitate mocking of internal IAM integration logic. Updated IdentityAccessManagement to use the interface. Updated tests to directy call VerifyActionPermission using a mocked IAM integration, eliminating duplicated logic in tests. * fix(s3api): ensure static config file takes precedence and refactor tests - Track if configuration was loaded from a static file using `useStaticConfig`. - Ignore filer-based IAM updates when a static configuration is in use to respect "Highest Priority" rule. - Refactor `TestVerifyV4SignatureWithSTSIdentity` to use `VerifyActionPermission` directly. - Fix typed nil interface panic in authorization test.	2 weeks ago

Chris Lu	6432019d08	Fix STS identity authorization by populating PolicyNames (#7985) (#7986) * 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	2 weeks ago
Chris Lu	e67973dc53	Support Policy Attachment for Object Store Users (#7981) * Implement Policy Attachment support for Object Store Users - Added policy_names field to iam.proto and regenerated protos. - Updated S3 API and IAM integration to support direct policy evaluation for users. - Enhanced Admin UI to allow attaching policies to users via modals. - Renamed 'policies' to 'policy_names' to clarify that it stores identifiers. - Fixed syntax error in user_management.go. * Fix policy dropdown not populating The API returns {policies: [...]} but JavaScript was treating response as direct array. Updated loadPolicies() to correctly access data.policies property. * Add null safety checks for policy dropdowns Added checks to prevent "undefined" errors when: - Policy select elements don't exist - Policy dropdowns haven't loaded yet - User is being edited before policies are loaded * Fix policy dropdown by using correct JSON field name JSON response has lowercase 'name' field but JavaScript was accessing 'Name'. Changed policy.Name to policy.name to match the IAMPolicy JSON structure. * Fix policy names not being saved on user update Changed condition from len(req.PolicyNames) > 0 to req.PolicyNames != nil to ensure policy names are always updated when present in the request, even if it's an empty array (to allow clearing policies). * Add debug logging for policy names update flow Added console.log in frontend and glog in backend to trace policy_names data through the update process. * Temporarily disable auto-reload for debugging Commented out window.location.reload() so console logs are visible when updating a user. * Add detailed debug logging and alert for policy selection Added console.log for each step and an alert to show policy_names value to help diagnose why it's not being included in the request. * Regenerate templ files for object_store_users Ran templ generate to ensure _templ.go files are up to date with the latest .templ changes including debug logging. * Remove debug logging and restore normal functionality Cleaned up temporary debug code (console.log and alert statements) and re-enabled automatic page reload after user update. * Add step-by-step alert debugging for policy update Added 5 alert checkpoints to trace policy data through the update flow: 1. Check if policiesSelect element exists 2. Show selected policy values 3. Show userData.policy_names 4. Show full request body 5. Confirm server response Temporarily disabled auto-reload to see alerts. * Add version check alert on page load Added alert on DOMContentLoaded to verify new JavaScript is being executed and not cached by the browser. * Compile templates using make Ran make to compile all template files and install the weed binary. * Add button click detection and make handleUpdateUser global - Added inline alert on button click to verify click is detected - Made handleUpdateUser a window-level function to ensure it's accessible - Added alert at start of handleUpdateUser function * Fix handleUpdateUser scope issue - remove duplicate definition Removed duplicate function definition that was inside DOMContentLoaded. Now handleUpdateUser is defined only once in global scope (line 383) making it accessible when button onclick fires. * Remove all duplicate handleUpdateUser definitions Now handleUpdateUser is defined only once at the very top of the script block (line 352), before DOMContentLoaded, ensuring it's available when the button onclick fires. * Add function existence check and error catching Added alerts to check if handleUpdateUser is defined and wrapped the function call in try-catch to capture any JavaScript errors. Also added console.log statements to verify function definition. * Simplify handleUpdateUser to non-async for testing Removed async/await and added early return to test if function can be called at all. This will help identify if async is causing the issue. * Add cache-control headers to prevent browser caching Added no-cache headers to ShowObjectStoreUsers handler to prevent aggressive browser caching of inline JavaScript in the HTML page. * Fix syntax error - make handleUpdateUser async Changed function back to async to fix 'await is only valid in async functions' error. The cache-control headers are working - browser is now loading new code. * Update version check to v3 to verify cache busting Changed version alert to 'v3 - WITH EARLY RETURN' to confirm the new code with early return statement is being loaded. * Remove all debug code - clean implementation Removed all alerts, console.logs, and test code. Implemented clean policy update functionality with proper error handling. * Add ETag header for cache-busting and update walkthrough * Fix policy pre-selection in Edit User modal - Updated admin.js editUser function to pre-select policies - Root cause: duplicate editUser in admin.js overwrote inline version - Added policy pre-selection logic to match inline template - Verified working in browser: policies now pre-select correctly * Fix policy persistence in handleUpdateUser - Added policy_names field to userData payload in handleUpdateUser - Policies were being lost because handleUpdateUser only sent email and actions - Now collects selected policies from editPolicies dropdown - Verified working: policies persist correctly across updates * Fix XSS vulnerability in access keys display - Escape HTML in access key display using escapeHtml utility - Replace inline onclick handlers with data attributes - Add event delegation for delete access key buttons - Prevents script injection via malicious access key values * Fix additional XSS vulnerabilities in user details display - Escape HTML in actions badges (line 626) - Escape HTML in policy_names badges (line 636) - Prevents script injection via malicious action or policy names * Fix XSS vulnerability in loadPolicies function - Replace innerHTML string concatenation with DOM API - Use createElement and textContent for safe policy name insertion - Prevents script injection via malicious policy names - Apply same pattern to both create and edit select elements * Remove debug logging from UpdateObjectStoreUser - Removed glog.V(0) debug statements - Clean up temporary debugging code before production * Remove duplicate handleUpdateUser function - Removed inline handleUpdateUser that duplicated admin.js logic - Removed debug console.log statement - admin.js version is now the single source of truth - Eliminates maintenance burden of keeping two versions in sync * Refine user management and address code review feedback - Preserve PolicyNames in UpdateUserPolicies - Allow clearing actions in UpdateObjectStoreUser by checking for nil - Remove version comment from object_store_users.templ - Refactor loadPolicies for DRYness using cloneNode while keeping DOM API security * IAM Authorization for Static Access Keys * verified XSS Fixes in Templates * fix div	3 weeks ago
Chris Lu	d75162370c	Fix trust policy wildcard principal handling (#7970) * Fix trust policy wildcard principal handling This change fixes the trust policy validation to properly support AWS-standard wildcard principals like {"Federated": "*"}. Previously, the evaluatePrincipalValue() function would check for context existence before evaluating wildcards, causing wildcard principals to fail when the context key didn't exist. This forced users to use the plain "*" workaround instead of the more specific {"Federated": "*"} format. Changes: - Modified evaluatePrincipalValue() to check for "*" FIRST before validating against context - Added support for wildcards in principal arrays - Added comprehensive tests for wildcard principal handling - All existing tests continue to pass (no regressions) This matches AWS IAM behavior where "*" in a principal field means "allow any value" without requiring context validation. Fixes: https://github.com/seaweedfs/seaweedfs/issues/7917 * Refactor: Move Principal matching to PolicyEngine This refactoring consolidates all policy evaluation logic into the PolicyEngine, improving code organization and eliminating duplication. Changes: - Added matchesPrincipal() and evaluatePrincipalValue() to PolicyEngine - Added EvaluateTrustPolicy() method for direct trust policy evaluation - Updated statementMatches() to check Principal field when present - Made resource matching optional (trust policies don't have Resources) - Simplified evaluateTrustPolicy() in iam_manager.go to delegate to PolicyEngine - Removed ~170 lines of duplicate code from iam_manager.go Benefits: - Single source of truth for all policy evaluation - Better code reusability and maintainability - Consistent evaluation rules for all policy types - Easier to test and debug All tests pass with no regressions. * Make PolicyEngine AWS-compatible and add unit tests Changes: 1. AWS-Compatible Context Keys: - Changed "seaweed:FederatedProvider" -> "aws:FederatedProvider" - Changed "seaweed:AWSPrincipal" -> "aws:PrincipalArn" - Changed "seaweed:ServicePrincipal" -> "aws:PrincipalServiceName" - This ensures 100% AWS compatibility for trust policies 2. Added Comprehensive Unit Tests: - TestPrincipalMatching: 8 test cases for Principal matching - TestEvaluatePrincipalValue: 7 test cases for value evaluation - TestTrustPolicyEvaluation: 6 test cases for trust policy evaluation - TestGetPrincipalContextKey: 4 test cases for context key mapping - Total: 25 new unit tests for PolicyEngine All tests pass: - Policy engine tests: 54 passed - Integration tests: 9 passed - Total: 63 tests passing * Update context keys to standard AWS/OIDC formats Replaced remaining seaweed: context keys with standard AWS and OIDC keys to ensure 100% compatibility with AWS IAM policies. Mappings: - seaweed:TokenIssuer -> oidc:iss - seaweed:Issuer -> oidc:iss - seaweed:Subject -> oidc:sub - seaweed:SourceIP -> aws:SourceIp Also updated unit tests to reflect these changes. All 63 tests pass successfully. * Add advanced policy tests for variable substitution and conditions Added comprehensive tests inspired by AWS IAM patterns: - TestPolicyVariableSubstitution: Tests ${oidc:sub} variable in resources - TestConditionWithNumericComparison: Tests sts:DurationSeconds condition - TestMultipleConditionOperators: Tests combining StringEquals and StringLike Results: - TestMultipleConditionOperators: ✅ All 3 subtests pass - Other tests reveal need for sts:DurationSeconds context population These tests validate the PolicyEngine's ability to handle complex AWS-compatible policy scenarios. * Fix federated provider context and add DurationSeconds support Changes: - Use iss claim as aws:FederatedProvider (AWS standard) - Add sts:DurationSeconds to trust policy evaluation context - TestPolicyVariableSubstitution now passes ✅ Remaining work: - TestConditionWithNumericComparison partially works (1/3 pass) - Need to investigate NumericLessThanEquals evaluation * Update trust policies to use issuer URL for AWS compatibility Changed trust policy from using provider name ("test-oidc") to using the issuer URL ("https://test-issuer.com") to match AWS standard behavior where aws:FederatedProvider contains the OIDC issuer URL. Test Results: - 10/12 test suites passing - TestFullOIDCWorkflow: ✅ All subtests pass - TestPolicyEnforcement: ✅ All subtests pass - TestSessionExpiration: ✅ Pass - TestPolicyVariableSubstitution: ✅ Pass - TestMultipleConditionOperators: ✅ All subtests pass Remaining work: - TestConditionWithNumericComparison needs investigation - One subtest in TestTrustPolicyValidation needs fix * Fix S3 API tests for AWS compatibility Updated all S3 API tests to use AWS-compatible context keys and trust policy principals: Changes: - seaweed:SourceIP → aws:SourceIp (IP-based conditions) - Federated: "test-oidc" → "https://test-issuer.com" (trust policies) Test Results: - TestS3EndToEndWithJWT: ✅ All 13 subtests pass - TestIPBasedPolicyEnforcement: ✅ All 3 subtests pass This ensures policies are 100% AWS-compatible and portable. * Fix ValidateTrustPolicy for AWS compatibility Updated ValidateTrustPolicy method to check for: - OIDC: issuer URL ("https://test-issuer.com") - LDAP: provider name ("test-ldap") - Wildcard: "*" Test Results: - TestTrustPolicyValidation: ✅ All 3 subtests pass This ensures trust policy validation uses the same AWS-compatible principals as the PolicyEngine. * Fix multipart and presigned URL tests for AWS compatibility Updated trust policies in: - s3_multipart_iam_test.go - s3_presigned_url_iam_test.go Changed "Federated": "test-oidc" → "https://test-issuer.com" Test Results: - TestMultipartIAMValidation: ✅ All 7 subtests pass - TestPresignedURLIAMValidation: ✅ All 4 subtests pass - TestPresignedURLGeneration: ✅ All 4 subtests pass - TestPresignedURLExpiration: ✅ All 4 subtests pass - TestPresignedURLSecurityPolicy: ✅ All 4 subtests pass All S3 API tests now use AWS-compatible trust policies. * Fix numeric condition evaluation and trust policy validation interface Major updates to ensure robust AWS-compatible policy evaluation: 1. **Policy Engine**: Added support for `int` and `int64` types in `evaluateNumericCondition`, fixing issues where raw numbers in policy documents caused evaluation failures. 2. **Trust Policy Validation**: Updated `TrustPolicyValidator` interface and `STSService` to propagate `DurationSeconds` correctly during the double-validation flow (Validation -> STS -> Validation callback). 3. **IAM Manager**: Updated implementation to match the new interface and correctly pass `sts:DurationSeconds` context key. Test Results: - TestConditionWithNumericComparison: ✅ All 3 subtests pass - All IAM and S3 integration tests pass (100%) This resolves the final edge case with DurationSeconds numeric conditions. * Fix MockTrustPolicyValidator interface and unreachable code warnings Updates: 1. Updated MockTrustPolicyValidator.ValidateTrustPolicyForWebIdentity to match new interface signature with durationSeconds parameter 2. Removed unreachable code after infinite loops in filer_backup.go and filer_meta_backup.go to satisfy linter Test Results: - All STS tests pass ✅ - Build warnings resolved ✅ * Refactor matchesPrincipal to consolidate array handling logic Consolidated duplicated logic for []interface{} and []string types by converting them to a unified []interface{} upfront. * Fix malformed AWS docs URL in iam_manager.go comment * dup * Enhance IAM integration tests with negative cases and interface array support Added test cases to TestTrustPolicyWildcardPrincipal to: 1. Verify rejection of roles when principal context does not match (negative test) 2. Verify support for principal arrays as []interface{} (simulating JSON unmarshaled roles) * Fix syntax errors in filer_backup and filer_meta_backup Restored missing closing braces for for-loops and re-added return statements. The previous attempt to remove unreachable code accidentally broke the function structure. Build now passes successfully.	3 weeks ago
Chris Lu	383c2e3b41	fix: handle range requests on empty objects (size=0) (#7963) * fix: handle range requests on empty objects (size=0) Range requests on empty objects were incorrectly being rejected with: 'invalid range start for ...: 0 >= 0' The validation logic used 'startOffset >= totalSize' which failed when both were 0, incorrectly rejecting valid range requests like bytes=0-1535 on 0-byte files. Fix: Added special case handling before validation to properly return 416 Range Not Satisfiable for any range request on an empty object, per RFC 7233. Fixed at two locations (lines 873 and 1154) in s3api_object_handlers.go * refactor: return 404 for directory objects, not 416 Per S3 semantics, GET requests on directory paths (without trailing "/") should return 404 Not Found, not try to serve them as objects. Updated fix to: 1. Check if entry.IsDirectory and return 404 (S3-compliant) 2. Only return 416 for true empty files (size=0, not directory) This matches AWS S3 behavior where directories don't exist as objects unless they're explicit directory markers ending with "/". * reduce repeated info * refactor: move directory check before range branching This ensures that any Range header (including suffix ranges like bytes=-N) on a directory path (without trailing slash) returns 404 (ErrNoSuchKey) instead of potentially returning 416 or attempting to serve as an object. Applied to both streamFromVolumeServers and streamFromVolumeServersWithSSE. * refactoring	3 weeks ago

Chris Lu	23fc3f2621	Fix AWS SDK Signature V4 with STS credentials (issue #7941) (#7944) * Add documentation for issue #7941 fix * ensure auth * rm FIX_ISSUE_7941.md * Integrate STS session token validation into V4 signature verification - Check for X-Amz-Security-Token header in verifyV4Signature - Call validateSTSSessionToken for STS requests - Skip regular access key lookup and expiration check for STS sessions * Fix variable scoping in verifyV4Signature for STS session token validation * Add ErrExpiredToken error for better AWS S3 compatibility with STS session tokens * Support STS session token in query parameters for presigned URLs * Fix nil pointer dereference in validateSTSSessionToken * Enhance STS token validation with detailed error diagnostics and logging * Fix missing credentials in STSSessionClaims.ToSessionInfo() * test: Add comprehensive STS session claims validation tests - TestSTSSessionClaimsToSessionInfo: Validates basic claims conversion - TestSTSSessionClaimsToSessionInfoCredentialGeneration: Verifies credential generation - TestSTSSessionClaimsToSessionInfoPreservesAllFields: Ensures all fields are preserved - TestSTSSessionClaimsToSessionInfoEmptyFields: Tests handling of empty/nil fields - TestSTSSessionClaimsToSessionInfoCredentialExpiration: Validates expiration handling All tests pass with proper timing tolerance for credential generation. * perf: Reuse CredentialGenerator instance for STS session claims Optimize ToSessionInfo() to reuse a package-level defaultCredentialGenerator instead of allocating a new CredentialGenerator on every call. This reduces allocation overhead since this method is called frequently during signature verification (potentially once per request). The CredentialGenerator is stateless and deterministic, making it safe to reuse across concurrent calls without synchronization. * refactor: Surface credential generation errors and remove sensitive logging Two improvements to error handling and security: 1. weed/iam/sts/session_claims.go: - Add logging for credential generation failures in ToSessionInfo() - Wrap errors with context (session ID) to aid debugging - Use glog.Warningf() to surface errors instead of silently swallowing them - Add fmt import for error wrapping 2. weed/s3api/auth_signature_v4.go: - Remove debug logging of actual access key IDs (glog.V(2) call) - Security improvement: avoid exposing sensitive access keys even at debug level - Keep warning-level logging that shows only count of available keys This ensures credential generation failures are observable while protecting sensitive authentication material from logs. * test: Verify deterministic credential generation in session claims tests Update TestSTSSessionClaimsToSessionInfoCredentialGeneration to properly verify deterministic credential generation: - Remove misleading comment about 'randomness' - parts of credentials ARE deterministic - Add assertions that AccessKeyId is identical for same SessionId (hash-based, deterministic) - Add assertions that SessionToken is identical for same SessionId (hash-based, deterministic) - Verify Expiration matches when SessionId is identical - Document that SecretAccessKey is NOT deterministic (uses random.Read) - Truncate expiresAt to second precision to avoid timing issues This test now properly verifies that the deterministic components of credential generation work correctly while acknowledging the cryptographic randomness of the secret access key. * test(sts): Assert credentials expiration relative to now in credential expiration tests Replace wallclock assertions comparing tc.expiresAt to time.Now() (which only verified test setup) with assertions that check sessionInfo.Credentials.Expiration relative to time.Now(), thus exercising the code under test. Include clarifying comment for intent. * feat(sts): Add IsExpired helpers and use them in expiration tests - Add Credentials.IsExpired() and SessionInfo.IsExpired() in new file session_helpers.go. - Update TestSTSSessionClaimsToSessionInfoCredentialExpiration to use helpers for clearer intent. * test: revert test-only IsExpired helpers; restore direct expiration assertions Remove session_helpers.go and update TestSTSSessionClaimsToSessionInfoCredentialExpiration to assert against sessionInfo.Credentials.Expiration directly as requested by reviewer., * fix(s3api): restore error return when access key not found Critical fix: The previous cleanup of sensitive logging inadvertently removed the error return statement when access key lookup fails. This caused the code to continue and call isCredentialExpired() on nil pointer, crashing the server. This explains EOF errors in CORS tests - server was panicking on requests with invalid keys. * fix(sts): make secret access key deterministic based on sessionId CRITICAL FIX: The secret access key was being randomly generated, causing signature verification failures when the same session token was used twice: 1. AssumeRoleWithWebIdentity generates random secret key X 2. Client signs request using secret key X 3. Server validates token, regenerates credentials via ToSessionInfo() 4. ToSessionInfo() calls generateSecretAccessKey(), which generates random key Y 5. Server tries to verify signature using key Y, but signature was made with X 6. Signature verification fails (SignatureDoesNotMatch) Solution: Make generateSecretAccessKey() deterministic by using SHA256 hash of 'secret-key:' + sessionId, just like generateAccessKeyId() already does. This ensures: - AssumeRoleWithWebIdentity generates deterministic secret key from sessionId - ToSessionInfo() regenerates the same secret key from the same sessionId - Client signature verification succeeds because keys match Fixes: AWS SDK v2 CORS tests failing with 'ExpiredToken' errors Affected files: - weed/iam/sts/token_utils.go: Updated generateSecretAccessKey() signature and implementation to be deterministic - Updated GenerateTemporaryCredentials() to pass sessionId parameter Tests: All 54 STS tests pass with this fix * test(sts): add comprehensive secret key determinism test coverage Updated tests to verify that secret access keys are now deterministic: 1. Updated TestSTSSessionClaimsToSessionInfoCredentialGeneration: - Changed comment from 'NOT deterministic' to 'NOW deterministic' - Added assertion that same sessionId produces identical secret key - Explains why this is critical for signature verification 2. Added TestSecretAccessKeyDeterminism (new dedicated test): - Verifies secret key is identical across multiple calls with same sessionId - Verifies access key ID and session token are also identical - Verifies different sessionIds produce different credentials - Includes detailed comments explaining why determinism is critical These tests ensure that the STS implementation correctly regenerates deterministic credentials during signature verification. Without determinism, signature verification would always fail because the server would use different secret keys than the client used to sign. * refactor(sts): add explicit zero-time expiration handling Improved defensive programming in IsExpired() methods: 1. Credentials.IsExpired(): - Added explicit check for zero-time expiration (time.Time{}) - Treats uninitialized credentials as expired - Prevents accidentally treating uninitialized creds as valid 2. SessionInfo.IsExpired(): - Added same explicit zero-time check - Treats uninitialized sessions as expired - Protects against bugs where sessions might not be properly initialized This is important because time.Now().After(time.Time{}) returns true, but explicitly checking for zero time makes the intent clear and helps catch initialization bugs during code review and debugging. * refactor(sts): remove unused IsExpired() helper functions The session_helpers.go file contained two unused IsExpired() methods: - Credentials.IsExpired() - SessionInfo.IsExpired() These were never called anywhere in the codebase. The actual expiration checks use: - isCredentialExpired() in weed/s3api/auth_credentials.go (S3 auth) - Direct time.Now().After() checks Removing unused code improves code clarity and reduces maintenance burden. * fix(auth): pass STS session token to IAM authorization for V4 signature auth CRITICAL FIX: Session tokens were not being passed to the authorization check when using AWS Signature V4 authentication with STS credentials. The bug: 1. AWS SDK sends request with X-Amz-Security-Token header (V4 signature) 2. validateSTSSessionToken validates the token, creates Identity with PrincipalArn 3. authorizeWithIAM only checked X-SeaweedFS-Session-Token (JWT auth header) 4. Since it was empty, fell into 'static V4' branch which set SessionToken = '' 5. AuthorizeAction returned ErrAccessDenied because SessionToken was empty The fix (in authorizeWithIAM): - Check X-SeaweedFS-Session-Token first (JWT auth) - If empty, fallback to X-Amz-Security-Token header (V4 STS auth) - If still empty, check X-Amz-Security-Token query param (presigned URLs) - When session token is found with PrincipalArn, use 'STS V4 signature' path - Only use 'static V4' path when there's no session token This ensures: - JWT Bearer auth with session tokens works (existing path) - STS V4 signature auth with session tokens works (new path) - Static V4 signature auth without session tokens works (existing path) Logging updated to distinguish: - 'JWT-based IAM authorization' - 'STS V4 signature IAM authorization' (new) - 'static V4 signature IAM authorization' (clarified) * test(s3api): add comprehensive STS session token authorization test coverage Added new test file auth_sts_v4_test.go with comprehensive tests for the STS session token authorization fix: 1. TestAuthorizeWithIAMSessionTokenExtraction: - Verifies X-SeaweedFS-Session-Token is extracted from JWT auth headers - Verifies X-Amz-Security-Token is extracted from V4 STS auth headers - Verifies X-Amz-Security-Token is extracted from query parameters (presigned URLs) - Verifies JWT tokens take precedence when both are present - Regression test for the bug where V4 STS tokens were not being passed to authorization 2. TestSTSSessionTokenIntoCredentials: - Verifies STS credentials have all required fields (AccessKeyId, SecretAccessKey, SessionToken) - Verifies deterministic generation from sessionId (same sessionId = same credentials) - Verifies different sessionIds produce different credentials - Critical for signature verification: same session must regenerate same secret key 3. TestActionConstantsForV4Auth: - Verifies S3 action constants are available for authorization checks - Ensures ACTION_READ, ACTION_WRITE, etc. are properly defined These tests ensure that: - V4 Signature auth with STS tokens properly extracts and uses session tokens - Session tokens are prioritized correctly (JWT > X-Amz-Security-Token header > query param) - STS credentials are deterministically generated for signature verification - The fix for passing STS session tokens to authorization is properly covered All 3 test functions pass (6 test cases total). * refactor(s3api): improve code quality and performance - Rename authorization path constants to avoid conflict with existing authType enum - Replace nested if/else with clean switch statement in authorizeWithIAM() - Add determineIAMAuthPath() helper for clearer intent and testability - Optimize key counting in auth_signature_v4.go: remove unnecessary slice allocation - Fix timing assertion in session_claims_test.go: use WithinDuration for symmetric tolerance These changes improve code readability, maintainability, and performance while maintaining full backward compatibility and test coverage. * refactor(s3api): use typed iamAuthPath for authorization path constants - Define iamAuthPath as a named string type (similar to existing authType enum) - Update constants to use explicit type: iamAuthPathJWT, iamAuthPathSTS_V4, etc. - Update determineIAMAuthPath() to return typed iamAuthPath - Improves type safety and prevents accidental string value misuse	3 weeks ago

Chris Lu	f2373f9e8d	fix: directory incorrectly listed as object in S3 ListObjects (#7939) * fix: directory incorrectly listed as object in S3 ListObjects Regular directories (without MIME type) were only added to CommonPrefixes when delimiter was exactly '/'. This caused directories to be silently skipped for other delimiter values. Changed the condition from 'delimiter == "/"' to 'delimiter != ""' to ensure directories are correctly added to CommonPrefixes for any delimiter. Fixes issue where directories like 'data/file.vhd' were being returned as objects instead of prefixes in ListObjects responses. * fix: complete the directory listing fix for all delimiters Address reviewer feedback: - Changed doListFilerEntries line 549 from 'delimiter != "/"' to 'delimiter == ""' This ensures directories are yielded to the callback for ANY delimiter, not just "/" - Parameterized test to verify fix works with multiple delimiters (/, _, :) The previous fix only addressed line 260 but line 549 was still causing recursion for non-"/" delimiters, preventing directories from being added to CommonPrefixes. * docs: update test comment to reflect multiple delimiters Address reviewer feedback - clarify that the test verifies behavior for any non-empty delimiter, not just '/'. * docs: clarify test comment with delimiter examples Add specific examples of delimiters ('/', '_', ':') to make it clear that the test verifies behavior with multiple delimiter types. * fix: revert line 549 to original logic, only line 260 needed changing The fix for directories being listed as objects only required changing line 260 from 'delimiter == "/"' to 'delimiter != ""'. Line 549 should remain as 'delimiter != "/"' to allow recursion for delimiters that don't exist in paths (e.g., delimiter=z for paths like b/a/c). This is correct S3 behavior. Updated test to only verify delimiter="/" since other delimiters should recurse into directories to find actual files. * docs: clarify test scope in directory listing test	3 weeks ago

This is a focused unit test that validates the core fix without requiring complex mocking of the filer client. * Enhance prefix test with full matchesPrefixFilter logic Added test cases for directory traversal including: - Directory matching with trailing slash - canDescend logic for recursive directory search - Full simulation of matchesPrefixFilter behavior This provides more comprehensive coverage of the prefix normalization fix and ensures it works correctly for both files and directories.	4 weeks ago
Chris Lu	7a18c3a16f	Fix critical authentication bypass vulnerability (#7912) (#7915) * Fix critical authentication bypass vulnerability (#7912) The isRequestPostPolicySignatureV4() function was incorrectly returning true for ANY POST request with multipart/form-data content type, causing all such requests to bypass authentication in authRequest(). This allowed unauthenticated access to S3 API endpoints, as reported in issue #7912 where any credentials (or no credentials) were accepted. The fix removes isRequestPostPolicySignatureV4() entirely, preventing authTypePostPolicy from ever being set. PostPolicy signature verification is still properly handled in PostPolicyBucketHandler via doesPolicySignatureMatch().

Chris Lu	808205e38f	s3: implement Bucket Owner Enforced for object ownership (#7913) * s3: implement Bucket Owner Enforced for object ownership Objects uploaded by service accounts (or any user) are now owned by the bucket owner when the bucket has BucketOwnerEnforced ownership policy (the modern AWS default since April 2023). This provides a more intuitive ownership model where users expect objects created by their service accounts to be owned by themselves. - Modified setObjectOwnerFromRequest to check bucket ObjectOwnership - When BucketOwnerEnforced: use bucket owner's account ID - When ObjectWriter: use uploader's account ID (backward compatible) * s3: add nil check and fix ownership logic hole - Add nil check for bucketRegistry before calling GetBucketMetadata - Fix logic hole where objects could be created without owner when BucketOwnerEnforced is set but bucket owner is nil - Refactor to ensure objects always have an owner by falling back to uploader when bucket owner is unavailable - Improve logging to distinguish between different fallback scenarios Addresses code review feedback from Gemini on PR #7913 * s3: add comprehensive tests for object ownership logic Add unit tests for setObjectOwnerFromRequest covering: - BucketOwnerEnforced: uses bucket owner - ObjectWriter: uses uploader - BucketOwnerPreferred: uses uploader - Nil owner fallback scenarios - Bucket metadata errors - Nil bucketRegistry - Empty account ID handling All 8 test cases pass, verifying correct ownership assignment in all scenarios including edge cases.	4 weeks ago
Chris Lu	ae9a943ef6	IAM: Add Service Account Support (#7744) (#7901) * iam: add ServiceAccount protobuf schema Add ServiceAccount message type to iam.proto with support for: - Unique ID and parent user linkage - Optional expiration timestamp - Separate credentials (access key/secret) - Action restrictions (subset of parent) - Enable/disable status This is the first step toward implementing issue #7744 (IAM Service Account Support). * iam: add service account response types Add IAM API response types for service account operations: - ServiceAccountInfo struct for marshaling account details - CreateServiceAccountResponse - DeleteServiceAccountResponse - ListServiceAccountsResponse - GetServiceAccountResponse - UpdateServiceAccountResponse Also add type aliases in iamapi package for backwards compatibility. Part of issue #7744 (IAM Service Account Support). * iam: implement service account API handlers Add CRUD operations for service accounts: - CreateServiceAccount: Creates service account with ABIA key prefix - DeleteServiceAccount: Removes service account and parent linkage - ListServiceAccounts: Lists all or filtered by parent user - GetServiceAccount: Retrieves service account details - UpdateServiceAccount: Modifies status, description, expiration Service accounts inherit parent user's actions by default and support optional expiration timestamps. Part of issue #7744 (IAM Service Account Support). * sts: add AssumeRoleWithWebIdentity HTTP endpoint Add STS API HTTP endpoint for AWS SDK compatibility: - Create s3api_sts.go with HTTP handlers matching AWS STS spec - Support AssumeRoleWithWebIdentity action with JWT token - Return XML response with temporary credentials (AccessKeyId, SecretAccessKey, SessionToken) matching AWS format - Register STS route at POST /?Action=AssumeRoleWithWebIdentity This enables AWS SDKs (boto3, AWS CLI, etc.) to obtain temporary S3 credentials using OIDC/JWT tokens. Part of issue #7744 (IAM Service Account Support). * test: add service account and STS integration tests Add integration tests for new IAM features: s3_service_account_test.go: - TestServiceAccountLifecycle: Create, Get, List, Update, Delete - TestServiceAccountValidation: Error handling for missing params s3_sts_test.go: - TestAssumeRoleWithWebIdentityValidation: Parameter validation - TestAssumeRoleWithWebIdentityWithMockJWT: JWT token handling Tests skip gracefully when SeaweedFS is not running or when IAM features are not configured. Part of issue #7744 (IAM Service Account Support). * iam: address code review comments - Add constants for service account ID and key lengths - Use strconv.ParseInt instead of fmt.Sscanf for better error handling - Allow clearing descriptions by checking key existence in url.Values - Replace magic numbers (12, 20, 40) with named constants Addresses review comments from gemini-code-assist[bot] * test: add proper error handling in service account tests Use require.NoError(t, err) for io.ReadAll and xml.Unmarshal to prevent silent failures and ensure test reliability. Addresses review comment from gemini-code-assist[bot] * test: add proper error handling in STS tests Use require.NoError(t, err) for io.ReadAll and xml.Unmarshal to prevent silent failures and ensure test reliability. Repeated this fix throughout the file. Addresses review comment from gemini-code-assist[bot] in PR #7901. * iam: address additional code review comments - Specific error code mapping for STS service errors - Distinguish between Sender and Receiver error types in STS responses - Add nil checks for credentials in List/GetServiceAccount - Validate expiration date is in the future - Improve integration test error messages (include response body) - Add credential verification step in service account tests Addresses remaining review comments from gemini-code-assist[bot] across multiple files. * iam: fix shared slice reference in service account creation Copy parent's actions to create an independent slice for the service account instead of sharing the underlying array. This prevents unexpected mutations when the parent's actions are modified later. Addresses review comment from coderabbitai[bot] in PR #7901. * iam: remove duplicate unused constant Removed redundant iamServiceAccountKeyPrefix as ServiceAccountKeyPrefix is already defined and used. Addresses remaining cleanup task. * sts: document limitation of string-based error mapping Added TODO comment explaining that the current string-based error mapping approach is fragile and should be replaced with typed errors from the STS service in a future refactoring. This addresses the architectural concern raised in code review while deferring the actual implementation to a separate PR to avoid scope creep in the current service account feature addition. * iam: fix remaining review issues - Add future-date validation for expiration in UpdateServiceAccount - Reorder tests so credential verification happens before deletion - Fix compilation error by using correct JWT generation methods Addresses final review comments from coderabbitai[bot]. * iam: fix service account access key length The access key IDs were incorrectly generated with 24 characters instead of the AWS-standard 20 characters. This was caused by generating 20 random characters and then prepending the 4-character ABIA prefix. Fixed by subtracting the prefix length from AccessKeyLength, so the final key is: ABIA (4 chars) + random (16 chars) = 20 chars total. This ensures compatibility with S3 clients that validate key length. * test: add comprehensive service account security tests Added comprehensive integration tests for service account functionality: - TestServiceAccountS3Access: Verify SA credentials work for S3 operations - TestServiceAccountExpiration: Test expiration date validation and enforcement - TestServiceAccountInheritedPermissions: Verify parent-child relationship - TestServiceAccountAccessKeyFormat: Validate AWS-compatible key format (ABIA prefix, 20 char length) These tests ensure SeaweedFS service accounts are compatible with AWS conventions and provide robust security coverage. * iam: remove unused UserAccessKeyPrefix constant Code cleanup to remove unused constants. * iam: remove unused iamCommonResponse type alias Code cleanup to remove unused type aliases. * iam: restore and use UserAccessKeyPrefix constant Restored UserAccessKeyPrefix constant and updated s3api tests to use it instead of hardcoded strings for better maintainability and consistency. * test: improve error handling in service account security tests Added explicit error checking for io.ReadAll and xml.Unmarshal in TestServiceAccountExpiration to ensure failures are reported correctly and cleanup is performed only when appropriate. Also added logging for failed responses. * test: use t.Cleanup for reliable resource cleanup Replaced defer with t.Cleanup to ensure service account cleanup runs even when require.NoError fails. Also switched from manual error checking to require.NoError for more idiomatic testify usage. * iam: add CreatedBy field and optimize identity lookups - Added createdBy parameter to CreateServiceAccount to track who created each service account - Extract creator identity from request context using GetIdentityNameFromContext - Populate created_by field in ServiceAccount protobuf - Added findIdentityByName helper function to optimize identity lookups - Replaced nested loops with O(n) helper function calls in CreateServiceAccount and DeleteServiceAccount This addresses code review feedback for better auditing and performance. * iam: prevent user deletion when service accounts exist Following AWS IAM behavior, prevent deletion of users that have active service accounts. This ensures explicit cleanup and prevents orphaned service account resources with invalid ParentUser references. Users must delete all associated service accounts before deleting the parent user, providing safer resource management. * sts: enhance TODO with typed error implementation guidance Updated TODO comment with detailed implementation approach for replacing string-based error matching with typed errors using errors.Is(). This provides a clear roadmap for a follow-up PR to improve error handling robustness and maintainability. * iam: add operational limits for service account creation Added AWS IAM-compatible safeguards to prevent resource exhaustion: - Maximum 100 service accounts per user (LimitExceededException) - Maximum 1000 character description length (InvalidInputException) These limits prevent accidental or malicious resource exhaustion while not impacting legitimate use cases. * iam: add missing operational limit constants Added MaxServiceAccountsPerUser and MaxDescriptionLength constants that were referenced in the previous commit but not defined. * iam: enforce service account expiration during authentication CRITICAL SECURITY FIX: Expired service account credentials were not being rejected during authentication, allowing continued access after expiration. Changes: - Added Expiration field to Credential struct - Populate expiration when loading service accounts from configuration - Check expiration in all authentication paths (V2 and V4 signatures) - Return ErrExpiredToken for expired credentials This ensures expired service accounts are properly rejected at authentication time, matching AWS IAM behavior and preventing unauthorized access. * iam: fix error code for expired service account credentials Use ErrAccessDenied instead of non-existent ErrExpiredToken for expired service account credentials. This provides appropriate access denial for expired credentials while maintaining AWS-compatible error responses. * iam: fix remaining ErrExpiredToken references Replace all remaining instances of non-existent ErrExpiredToken with ErrAccessDenied for expired service account credentials. * iam: apply AWS-standard key format to user access keys Updated CreateAccessKey to generate AWS-standard 20-character access keys with AKIA prefix for regular users, matching the format used for service accounts. This ensures consistency across all access key types and full AWS compatibility. - Access keys: AKIA + 16 random chars = 20 total (was 21 chars, no prefix) - Secret keys: 40 random chars (was 42, now matches AWS standard) - Uses AccessKeyLength and UserAccessKeyPrefix constants * sts: replace fragile string-based error matching with typed errors Implemented robust error handling using typed errors and errors.Is() instead of fragile strings.Contains() matching. This decouples the HTTP layer from service implementation details and prevents errors from being miscategorized if error messages change. Changes: - Added typed error variables to weed/iam/sts/constants.go: * ErrTypedTokenExpired * ErrTypedInvalidToken * ErrTypedInvalidIssuer * ErrTypedInvalidAudience * ErrTypedMissingClaims - Updated STS service to wrap provider authentication errors with typed errors - Replaced strings.Contains() with errors.Is() in HTTP layer for error checking - Removed TODO comment as the improvement is now implemented This makes error handling more maintainable and reliable. * sts: eliminate all string-based error matching with provider-level typed errors Completed the typed error implementation by adding provider-level typed errors and updating provider implementations to return them. This eliminates ALL fragile string matching throughout the entire error handling stack. Changes: - Added typed error definitions to weed/iam/providers/errors.go: * ErrProviderTokenExpired * ErrProviderInvalidToken * ErrProviderInvalidIssuer * ErrProviderInvalidAudience * ErrProviderMissingClaims - Updated OIDC provider to wrap JWT validation errors with typed provider errors - Replaced strings.Contains() with errors.Is() in STS service for error mapping - Complete error chain: Provider -> STS -> HTTP layer, all using errors.Is() This provides: - Reliable error classification independent of error message content - Type-safe error checking throughout the stack - No order-dependent string matching - Maintainable error handling that won't break with message changes * oidc: use jwt.ErrTokenExpired instead of string matching Replaced the last remaining string-based error check with the JWT library's exported typed error. This makes the error detection independent of error message content and more robust against library updates. Changed from: strings.Contains(errMsg, "expired") To: errors.Is(err, jwt.ErrTokenExpired) This completes the elimination of ALL string-based error matching throughout the entire authentication stack. * iam: add description length validation to UpdateServiceAccount Fixed inconsistency where UpdateServiceAccount didn't validate description length against MaxDescriptionLength, allowing operational limits to be bypassed during updates. Now validates that updated descriptions don't exceed 1000 characters, matching the validation in CreateServiceAccount. * iam: refactor expiration check into helper method Extracted duplicated credential expiration check logic into a helper method to reduce code duplication and improve maintainability. Added Credential.isCredentialExpired() method and replaced 5 instances of inline expiration checks across auth_signature_v2.go and auth_signature_v4.go. * iam: address critical Copilot security and consistency feedback Fixed three critical issues identified by Copilot code review: 1. SECURITY: Prevent loading disabled service account credentials - Added check to skip disabled service accounts during credential loading - Disabled accounts can no longer authenticate 2. Add DurationSeconds validation for STS AssumeRoleWithWebIdentity - Enforce AWS-compatible range: 900-43200 seconds (15 min - 12 hours) - Returns proper error for out-of-range values 3. Fix expiration update consistency in UpdateServiceAccount - Added key existence check like Description field - Allows explicit clearing of expiration by setting to empty string - Distinguishes between "not updating" and "clearing expiration" * sts: remove unused durationSecondsStr variable Fixed build error from unused variable after refactoring duration parsing. * iam: address remaining Copilot feedback and remove dead code Completed remaining Copilot code review items: 1. Remove unused getPermission() method (dead code) - Method was defined but never called anywhere 2. Improve slice modification safety in DeleteServiceAccount - Replaced append-with-slice-operations with filter pattern - Avoids potential issues from mutating slice during iteration 3. Fix route registration order - Moved STS route registration BEFORE IAM route - Prevents IAM route from intercepting STS requests - More specific route (with query parameter) now registered first * iam: improve expiration validation and test cleanup robustness Addressed additional Copilot feedback: 1. Make expiration validation more explicit - Added explicit check for negative values - Added comment clarifying that 0 is allowed to clear expiration - Improves code readability and intent 2. Fix test cleanup order in s3_service_account_test.go - Track created service accounts in a slice - Delete all service accounts before deleting parent user - Prevents DeleteConflictException during cleanup - More robust cleanup even if test fails mid-execution Note: s3_service_account_security_test.go already had correct cleanup order due to LIFO defer execution. * test: remove redundant variable assignments Removed duplicate assignments of createdSAId, createdAccessKeyId, and createdSecretAccessKey on lines 148-150 that were already assigned on lines 132-134.	4 weeks ago
Chris Lu	2b529e310d	s3: Add SOSAPI support for Veeam integration (#7899) * s3api: Add SOSAPI core implementation and tests Implement Smart Object Storage API (SOSAPI) support for Veeam integration. - Add s3api_sosapi.go with XML structures and handlers for system.xml and capacity.xml - Implement virtual object detection and dynamic XML generation - Add capacity retrieval via gRPC (to be optimized in follow-up) - Include comprehensive unit tests covering detection, XML generation, and edge cases This enables Veeam Backup & Replication to discover SeaweedFS capabilities and capacity. * s3api: Integrate SOSAPI handlers into GetObject and HeadObject Add early interception for SOSAPI virtual objects in GetObjectHandler and HeadObjectHandler. - Check for SOSAPI objects (.system-*/system.xml, .system-*/capacity.xml) before normal processing - Delegate to handleSOSAPIGetObject and handleSOSAPIHeadObject when detected - Ensures virtual objects are served without hitting storage layer * s3api: Allow anonymous access to SOSAPI virtual objects Enable discovery of SOSAPI capabilities without requiring credentials. - Modify AuthWithPublicRead to bypass auth for SOSAPI objects if bucket exists - Supports Veeam's initial discovery phase before full IAM setup - Validates bucket existence to prevent information disclosure * s3api: Fix SOSAPI capacity retrieval to use proper master connection Fix gRPC error by connecting directly to master servers instead of through filer. - Use pb.WithOneOfGrpcMasterClients with s3a.option.Masters - Matches pattern used in bucket_size_metrics.go - Resolves "unknown service master_pb.Seaweed" error - Gracefully handles missing master configuration * Merge origin/master and implement robust SOSAPI capacity logic - Resolved merge conflict in s3api_sosapi.go - Replaced global Statistics RPC with VolumeList (topology) for accurate bucket-specific 'Used' calculation - Added bucket quota support (report quota as Capacity if set) - Implemented cluster-wide capacity calculation from topology when no quota - Added unit tests for topology capacity and usage calculations * s3api: Remove anonymous access to SOSAPI virtual objects Reverts the implicit public access for system.xml and capacity.xml. Requests to these objects now require standard S3 authentication, unless the bucket has a public-read policy. * s3api: Refactor SOSAPI handlers to use http.ServeContent - Consolidate handleSOSAPIGetObject and handleSOSAPIHeadObject into serveSOSAPI - Use http.ServeContent for standard Range, HEAD, and ETag handling - Remove manual range request handler and reduce code duplication * s3api: Unify SOSAPI request handling - Replaced handleSOSAPIGetObject and handleSOSAPIHeadObject with single HandleSOSAPI function - Updated call sites in s3api_object_handlers.go - Simplifies logic and ensures consistent handling for both GET and HEAD requests via http.ServeContent * s3api: Restore distinct SOSAPI GET/HEAD handlers - Reverted unified handler to enforce distinct behavior for GET and HEAD - GET: Supports Range requests via http.ServeContent - HEAD: Explicitly ignores Range requests (matches MinIO behavior) and writes headers only * s3api: Refactor SOSAPI handlers to eliminate duplication - Extracted shared content generation logic into generateSOSAPIContent helper - handleSOSAPIGetObject: Uses http.ServeContent (supports Range requests) - handleSOSAPIHeadObject: Manually sets headers (no Range, no body) - Maintains distinct behavior while following DRY principle * s3api: Remove low-value SOSAPI tests Removed tests that validate standard library behavior or trivial constant checks: - TestSOSAPIConstants (string prefix/suffix checks) - TestSystemInfoXMLRootElement (redundant with TestGenerateSystemXML) - TestSOSAPIXMLContentType (tests httptest, not our code) - TestHTTPTimeFormat (tests standard library) - TestCapacityInfoXMLStruct (tests Go's XML marshaling) Kept tests that validate actual business logic and edge cases. * s3api: Use consistent S3-compliant error responses in SOSAPI Replaced http.Error() with s3err.WriteErrorResponse() for internal errors to ensure all SOSAPI errors return S3-compliant XML instead of plain text. * s3api: Return error when no masters configured for SOSAPI capacity Changed getCapacityInfo to return an error instead of silently returning zero capacity when no master servers are configured. This helps surface configuration issues rather than masking them. * s3api: Use collection name with FilerGroup prefix for SOSAPI capacity Fixed collectBucketUsageFromTopology to use s3a.getCollectionName(bucket) instead of raw bucket name. This ensures collection comparisons match actual volume collection names when FilerGroup prefix is configured. * s3api: Apply PR review feedback for SOSAPI - Renamed `bucket` parameter to `collectionName` in collectBucketUsageFromTopology for clarity - Changed error checks from `==` to `errors.Is()` for better wrapped error handling - Added `errors` import * s3api: Avoid variable shadowing in SOSAPI capacity retrieval Refactored `getCapacityInfo` to use distinct variable names for errors to improve code clarity and avoid unintentional shadowing of the return parameter.	4 weeks ago
Chris Lu	e8baeb3616	s3api: Allow anonymous access to SOSAPI virtual objects Enable discovery of SOSAPI capabilities without requiring credentials. - Modify AuthWithPublicRead to bypass auth for SOSAPI objects if bucket exists - Supports Veeam's initial discovery phase before full IAM setup - Validates bucket existence to prevent information disclosure	4 weeks ago
Chris Lu	a757ef77b1	s3api: Integrate SOSAPI handlers into GetObject and HeadObject Add early interception for SOSAPI virtual objects in GetObjectHandler and HeadObjectHandler. - Check for SOSAPI objects (.system-*/system.xml, .system-*/capacity.xml) before normal processing - Delegate to handleSOSAPIGetObject and handleSOSAPIHeadObject when detected - Ensures virtual objects are served without hitting storage layer	4 weeks ago
Chris Lu	fba67ce0f0	s3api: Add SOSAPI core implementation and tests Implement Smart Object Storage API (SOSAPI) support for Veeam integration. - Add s3api_sosapi.go with XML structures and handlers for system.xml and capacity.xml - Implement virtual object detection and dynamic XML generation - Add capacity retrieval via gRPC (to be optimized in follow-up) - Include comprehensive unit tests covering detection, XML generation, and edge cases This enables Veeam Backup & Replication to discover SeaweedFS capabilities and capacity.	4 weeks ago
