fix(s3): omit NotResource:null from bucket policy JSON response (#8658)
* fix(s3): omit NotResource:null from bucket policy JSON response (#8657) Change NotResource from value type to pointer (*StringOrStringSlice) so that omitempty properly omits it when unset, matching the existing Principal field pattern. This prevents IaC tools (Terraform, Ansible) from detecting false configuration drift. Add bucket policy round-trip idempotency integration tests. * simplify JSON comparison in bucket policy idempotency test Use require.JSONEq directly on the raw JSON strings instead of round-tripping through unmarshal/marshal, since JSONEq already handles normalization internally. * fix bucket policy test cases that locked out the admin user The Deny+NotResource test cases used Action:"s3:*" which denied the admin's own GetBucketPolicy call. Scope deny to s3:GetObject only, and add an Allow+NotResource variant instead. * fix(s3): also make Resource a pointer to fix empty string in JSON Apply the same omitempty pointer fix to the Resource field, which was emitting "Resource":"" when only NotResource was set. Add NewStringOrStringSlicePtr helper, make Strings() nil-safe, and handle *StringOrStringSlice in normalizeToStringSliceWithError. * improve bucket policy integration tests per review feedback - Replace time.Sleep with waitForClusterReady using ListBuckets - Use structural hasKey check instead of brittle substring NotContains - Assert specific NoSuchBucketPolicy error code after delete - Handle single-statement policies in hasKey helper |

s3/iam: reuse one request id per request (#8538)
* request_id: add shared request middleware
* s3err: preserve request ids in responses and logs
* iam: reuse request ids in XML responses
* sts: reuse request ids in XML responses
* request_id: drop legacy header fallback
* request_id: use AWS-style request id format
* iam: fix AWS-compatible XML format for ErrorResponse and field ordering
- ErrorResponse uses bare <RequestId> at root level instead of
<ResponseMetadata> wrapper, matching the AWS IAM error response spec
- Move CommonResponse to last field in success response structs so
<ResponseMetadata> serializes after result elements
- Add randomness to request ID generation to avoid collisions
- Add tests for XML ordering and ErrorResponse format
* iam: remove duplicate error_response_test.go
Test is already covered by responses_test.go.
* address PR review comments
- Guard against typed nil pointers in SetResponseRequestID before
interface assertion (CodeRabbit)
- Use regexp instead of strings.Index in test helpers for extracting
request IDs (Gemini)
* request_id: prevent spoofing, fix nil-error branch, thread reqID to error writers
- Ensure() now always generates a server-side ID, ignoring client-sent
x-amz-request-id headers to prevent request ID spoofing. Uses a
private context key (contextKey{}) instead of the header string.
- writeIamErrorResponse in both iamapi and embedded IAM now accepts
reqID as a parameter instead of calling Ensure() internally, ensuring
a single request ID per request lifecycle.
- The nil-iamError branch in writeIamErrorResponse now writes a 500
Internal Server Error response instead of returning silently.
- Updated tests to set request IDs via context (not headers) and added
tests for spoofing prevention and context reuse.
* sts: add request-id consistency assertions to ActionInBody tests
* test: update admin test to expect server-generated request IDs
The test previously sent a client x-amz-request-id header and expected
it echoed back. Since Ensure() now ignores client headers to prevent
spoofing, update the test to verify the server returns a non-empty
server-generated request ID instead.
* iam: add generic WithRequestID helper alongside reflection-based fallback
Add WithRequestID[T] that uses generics to take the address of a value
type, satisfying the pointer receiver on SetRequestId without reflection.
The existing SetResponseRequestID is kept for the two call sites that
operate on interface{} (from large action switches where the concrete
type varies at runtime). Generics cannot replace reflection there since
Go cannot infer type parameters from interface{}.
* Remove reflection and generics from request ID setting
Call SetRequestId directly on concrete response types in each switch
branch before boxing into interface{}, eliminating the need for
WithRequestID (generics) and SetResponseRequestID (reflection).
* iam: return pointer responses in action dispatch
* Fix IAM error handling consistency and ensure request IDs on all responses
- UpdateUser/CreatePolicy error branches: use writeIamErrorResponse instead
of s3err.WriteErrorResponse to preserve IAM formatting and request ID
- ExecuteAction: accept reqID parameter and generate one if empty, ensuring
every response carries a RequestId regardless of caller
* Clean up inline policies on DeleteUser and UpdateUser rename
DeleteUser: remove InlinePolicies[userName] from policy storage before
removing the identity, so policies are not orphaned.
UpdateUser: move InlinePolicies[userName] to InlinePolicies[newUserName]
when renaming, so GetUserPolicy/DeleteUserPolicy work under the new name.
Both operations persist the updated policies and return an error if
the storage write fails, preventing partial state.

Allow multipart upload operations when s3:PutObject is authorized (#8445)
* Allow multipart upload operations when s3:PutObject is authorized
Multipart upload is an implementation detail of putting objects, not a separate
permission. When a policy grants s3:PutObject, it should implicitly allow:
- s3:CreateMultipartUpload
- s3:UploadPart
- s3:CompleteMultipartUpload
- s3:AbortMultipartUpload
- s3:ListParts
This fixes a compatibility issue where clients like PyArrow that use multipart
uploads by default would fail even though the role had s3:PutObject permission.
The session policy intersection still applies - both the identity-based policy
AND session policy must allow s3:PutObject for multipart operations to work.
Implementation:
- Added constants for S3 multipart action strings
- Added multipartActionSet to efficiently check if action is multipart-related
- Updated MatchesAction method to implicitly grant multipart when PutObject allowed
* Update weed/s3api/policy_engine/types.go
Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>
* Add s3:ListMultipartUploads to multipart action set
Include s3:ListMultipartUploads in the multipartActionSet so that listing
multipart uploads is implicitly granted when s3:PutObject is authorized.
ListMultipartUploads is a critical part of the multipart upload workflow,
allowing clients to query in-progress uploads before completing them.
Changes:
- Added s3ListMultipartUploads constant definition
- Included s3ListMultipartUploads in multipartActionSet initialization
- Existing references to multipartActionSet automatically now cover ListMultipartUploads
All policy engine tests pass (0.351s execution time)
* Refactor: reuse multipart action constants from s3_constants package
Remove duplicate constant definitions from policy_engine/types.go and import
the canonical definitions from s3api/s3_constants/s3_actions.go instead.
This eliminates duplication and ensures a single source of truth for
multipart action strings:
- ACTION_CREATE_MULTIPART_UPLOAD
- ACTION_UPLOAD_PART
- ACTION_COMPLETE_MULTIPART
- ACTION_ABORT_MULTIPART
- ACTION_LIST_PARTS
- ACTION_LIST_MULTIPART_UPLOADS
All policy engine tests pass (0.350s execution time)
* Fix S3_ACTION_LIST_MULTIPART_UPLOADS constant value
Move S3_ACTION_LIST_MULTIPART_UPLOADS from bucket operations to multipart
operations section and change value from 's3:ListBucketMultipartUploads' to
's3:ListMultipartUploads' to match the action strings used in policy_engine
and s3_actions.go.
This ensures consistent action naming across all S3 constant definitions.
* refactor names
* Fix S3 action constant mismatches and MatchesAction early return bug
Fix two critical issues in policy engine:
1. S3Actions map had incorrect multipart action mappings:
- 'ListMultipartUploads' was 's3:ListMultipartUploads' (should be 's3:ListBucketMultipartUploads')
- 'ListParts' was 's3:ListParts' (should be 's3:ListMultipartUploadParts')
These mismatches caused authorization checks to fail for list operations
2. CompiledStatement.MatchesAction() had early return bug:
- Previously returned true immediately upon first direct action match
- This prevented scanning remaining matchers for s3:PutObject permission
- Now scans ALL matchers before returning, tracking both direct match and PutObject grant
- Ensures multipart operations inherit s3:PutObject authorization even when
explicitly requested action doesn't match (e.g., s3:ListMultipartUploadParts)
Changes:
- Track matchedAction flag to defer
Fix two critical issues in policy engine:
1. S3Actions map had incorrect multipart action mappings:
- 'ListMultipartUploads' was 's3:ListMultipartUplPer
1. S3Actions map had incorrect multiparAll - 'ListMultipartUploads(0.334s execution time)
* Refactor S3Actions map to use s3_constants
Replace hardcoded action strings in the S3Actions map with references to
canonical S3_ACTION_* constants from s3_constants/s3_action_strings.go.
Benefits:
- Single source of truth for S3 action values
- Eliminates string duplication across codebase
- Ensures consistency between policy engine and middleware
- Reduces maintenance burden when action strings need updates
All policy engine tests pass (0.334s execution time)
* Remove unused S3Actions map
The S3Actions map in types.go was never referenced anywhere in the codebase.
All action mappings are handled by GetActionMappings() in integration.go instead.
This removes 42 lines of dead code.
* Fix test: reload configuration function must also reload IAM state
TestEmbeddedIamAttachUserPolicyRefreshesIAM was failing because the test's
reloadConfigurationFunc only updated mockConfig but didn't reload the actual IAM
state. When AttachUserPolicy calls refreshIAMConfiguration(), it would use the
test's incomplete reload function instead of the real LoadS3ApiConfigurationFromCredentialManager().
Fixed by making the test's reloadConfigurationFunc also call
e.iam.LoadS3ApiConfigurationFromCredentialManager() so lookupByIdentityName()
sees the updated policy attachments.

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. |

fix: authenticate before parsing form in IAM API (#7803)
fix: authenticate before parsing form in IAM API (#7802) The AuthIam middleware was calling ParseForm() before AuthSignatureOnly(), which consumed the request body before signature verification could hash it. For IAM requests (service != 's3'), the signature verification needs to hash the request body. When ParseForm() was called first, the body was already consumed, resulting in an empty body hash and SignatureDoesNotMatch error. The fix moves authentication before form parsing. The streamHashRequestBody function preserves the body after reading, so ParseForm() works correctly after authentication. Fixes #7802 |

feat(iam): add SetUserStatus and UpdateAccessKey actions (#7750)
feat(iam): add SetUserStatus and UpdateAccessKey actions (#7745) Add ability to enable/disable users and access keys without deleting them. ## Changes ### Protocol Buffer Updates - Add `disabled` field (bool) to Identity message for user status - false (default) = enabled, true = disabled - No backward compatibility hack needed since zero value is correct - Add `status` field (string: Active/Inactive) to Credential message ### New IAM Actions - SetUserStatus: Enable or disable a user (requires admin) - UpdateAccessKey: Change access key status (self-service or admin) ### Behavior - Disabled users: All API requests return AccessDenied - Inactive access keys: Signature validation fails - Status check happens early in auth flow for performance - Backward compatible: existing configs default to enabled (disabled=false) ### Use Cases 1. Temporary suspension: Disable user access during investigation 2. Key rotation: Deactivate old key before deletion 3. Offboarding: Disable rather than delete for audit purposes 4. Emergency response: Quickly disable compromised credentials Fixes #7745 |

Embed IAM API into S3 server (#7740)
* Embed IAM API into S3 server This change simplifies the S3 and IAM deployment by embedding the IAM API directly into the S3 server, following the patterns used by MinIO and Ceph RGW. Changes: - Add -iam flag to S3 server (enabled by default) - Create embedded IAM API handler in s3api package - Register IAM routes (POST to /) in S3 server when enabled - Deprecate standalone 'weed iam' command with warning Benefits: - Single binary, single port for both S3 and IAM APIs - Simpler deployment and configuration - Shared credential manager between S3 and IAM - Backward compatible: 'weed iam' still works with deprecation warning Usage: - weed s3 -port=8333 # S3 + IAM on same port (default) - weed s3 -iam=false # S3 only, disable embedded IAM - weed iam -port=8111 # Deprecated, shows warning * Fix nil pointer panic: add s3.iam flag to weed server command The enableIam field was not initialized when running S3 via 'weed server', causing a nil pointer dereference when checking *s3opt.enableIam. * Fix nil pointer panic: add s3.iam flag to weed filer command The enableIam field was not initialized when running S3 via 'weed filer -s3', causing a nil pointer dereference when checking *s3opt.enableIam. * Add integration tests for embedded IAM API Tests cover: - CreateUser, ListUsers, GetUser, UpdateUser, DeleteUser - CreateAccessKey, DeleteAccessKey, ListAccessKeys - CreatePolicy, PutUserPolicy, GetUserPolicy - Implicit username extraction from authorization header - Full user lifecycle workflow test These tests validate the embedded IAM API functionality that was added in the S3 server, ensuring IAM operations work correctly when served from the same port as S3. * Security: Use crypto/rand for IAM credential generation SECURITY FIX: Replace math/rand with crypto/rand for generating access keys and secret keys. Using math/rand is not cryptographically secure and can lead to predictable credentials. This change: 1. Replaces math/rand with crypto/rand in both: - weed/s3api/s3api_embedded_iam.go (embedded IAM) - weed/iamapi/iamapi_management_handlers.go (standalone IAM) 2. Removes the seededRand variable that was initialized with time-based seed (predictable) 3. Updates StringWithCharset/iamStringWithCharset to: - Use crypto/rand.Int() for secure random index generation - Return an error for proper error handling 4. Updates CreateAccessKey to handle the new error return 5. Updates DoActions handlers to propagate errors properly * Fix critical bug: DeleteUserPolicy was deleting entire user instead of policy BUG FIX: DeleteUserPolicy was incorrectly deleting the entire user identity from s3cfg.Identities instead of just clearing the user's inline policy (Actions). Before (wrong): s3cfg.Identities = append(s3cfg.Identities[:i], s3cfg.Identities[i+1:]...) After (correct): ident.Actions = nil Also: - Added proper iamDeleteUserPolicyResponse / DeleteUserPolicyResponse types - Fixed return type from iamPutUserPolicyResponse to iamDeleteUserPolicyResponse Affected files: - weed/s3api/s3api_embedded_iam.go (embedded IAM) - weed/iamapi/iamapi_management_handlers.go (standalone IAM) - weed/iamapi/iamapi_response.go (response types) * Add tests for DeleteUserPolicy to prevent regression Added two tests: 1. TestEmbeddedIamDeleteUserPolicy - Verifies that: - User is NOT deleted (identity still exists) - Credentials are NOT deleted - Only Actions (policy) are cleared to nil 2. TestEmbeddedIamDeleteUserPolicyUserNotFound - Verifies: - Returns 404 when user doesn't exist These tests ensure the bug fixed in the previous commit (deleting user instead of policy) doesn't regress. * Fix race condition: Add mutex lock to IAM DoActions The DoActions function performs a read-modify-write operation on the shared IAM configuration without any locking. This could lead to race conditions and data loss if multiple requests modify the IAM config concurrently. Added mutex lock at the start of DoActions in both: - weed/s3api/s3api_embedded_iam.go (embedded IAM) - weed/iamapi/iamapi_management_handlers.go (standalone IAM) The lock protects the entire read-modify-write cycle: 1. GetS3ApiConfiguration (read) 2. Modify s3cfg based on action 3. PutS3ApiConfiguration (write) * Fix action comparison and document CreatePolicy limitation 1. Replace reflect.DeepEqual with order-independent string slice comparison - Added iamStringSlicesEqual/stringSlicesEqual helper functions - Prevents duplicate policy statements when actions are in different order 2. Document CreatePolicy limitation in embedded IAM - Added TODO comment explaining that managed policies are not persisted - Users should use PutUserPolicy for inline policies 3. Fix deadlock in standalone IAM's CreatePolicy - Removed nested lock acquisition (DoActions already holds the lock) Files changed: - weed/s3api/s3api_embedded_iam.go - weed/iamapi/iamapi_management_handlers.go * Add rate limiting to embedded IAM endpoint Apply circuit breaker rate limiting to the IAM endpoint to prevent abuse. Also added request tracking for IAM operations. The IAM endpoint now follows the same pattern as other S3 endpoints: - track() for request metrics - s3a.iam.Auth() for authentication - s3a.cb.Limit() for rate limiting * Fix handleImplicitUsername to properly look up username from AccessKeyId According to AWS spec, when UserName is not specified in an IAM request, IAM should determine the username implicitly based on the AccessKeyId signing the request. Previously, the code incorrectly extracted s[2] (region field) from the SigV4 credential string as the username. This fix: 1. Extracts the AccessKeyId from s[0] of the credential string 2. Looks up the AccessKeyId in the credential store using LookupByAccessKey 3. Uses the identity's Name field as the username if found Also: - Added exported LookupByAccessKey wrapper method to IdentityAccessManagement - Updated tests to verify correct access key lookup behavior - Applied fix to both embedded IAM and standalone IAM implementations * Fix CreatePolicy to not trigger unnecessary save CreatePolicy validates the policy document and returns metadata but does not actually store the policy (SeaweedFS uses inline policies attached via PutUserPolicy). However, 'changed' was left as true, triggering an unnecessary save operation. Set changed = false after successful CreatePolicy validation in both embedded IAM and standalone IAM implementations. * Improve embedded IAM test quality - Remove unused mock types (mockCredentialManager, mockEmbeddedIamApi) - Use proto.Clone instead of proto.Merge for proper deep copy semantics - Replace brittle regex-based XML error extraction with proper XML unmarshalling - Remove unused regexp import - Add state and field assertions to tests: - CreateUser: verify username in response and user persisted in config - ListUsers: verify response contains expected users - GetUser: verify username in response - CreatePolicy: verify policy metadata in response - PutUserPolicy: verify actions were attached to user - CreateAccessKey: verify credentials in response and persisted in config * Remove shared test state and improve executeEmbeddedIamRequest - Remove package-level embeddedIamApi variable to avoid shared test state - Update executeEmbeddedIamRequest to accept API instance as parameter - Only call xml.Unmarshal when v != nil, making nil-v cases explicit - Return unmarshal error properly instead of always returning it - Update all tests to create their own EmbeddedIamApiForTest instance - Each test now has isolated state, preventing test interdependencies * Add comprehensive test coverage for embedded IAM Added tests for previously uncovered functions: - iamStringSlicesEqual: 0% → 100% - iamMapToStatementAction: 40% → 100% - iamMapToIdentitiesAction: 30% → 70% - iamHash: 100% - iamStringWithCharset: 85.7% - GetPolicyDocument: 75% → 100% - CreatePolicy: 91.7% → 100% - DeleteUser: 83.3% → 100% - GetUser: 83.3% → 100% - ListAccessKeys: 55.6% → 88.9% New test cases for helper functions, error handling, and edge cases. * Document IAM code duplication and reference GitHub issue #7747 Added comments to both IAM implementations noting the code duplication and referencing the tracking issue for future refactoring: - weed/s3api/s3api_embedded_iam.go (embedded IAM) - weed/iamapi/iamapi_management_handlers.go (standalone IAM) See: https://github.com/seaweedfs/seaweedfs/issues/7747 * Implement granular IAM authorization for self-service operations Previously, all IAM actions required ACTION_ADMIN permission, which was overly restrictive. This change implements AWS-like granular permissions: Self-service operations (allowed without admin for own resources): - CreateAccessKey (on own user) - DeleteAccessKey (on own user) - ListAccessKeys (on own user) - GetUser (on own user) - UpdateAccessKey (on own user) Admin-only operations: - CreateUser, DeleteUser, UpdateUser - PutUserPolicy, GetUserPolicy, DeleteUserPolicy - CreatePolicy - ListUsers - Operations on other users The new AuthIam middleware: 1. Authenticates the request (signature verification) 2. Parses the IAM Action and target UserName 3. For self-service actions, allows if user is operating on own resources 4. For all other actions or operations on other users, requires admin * Fix misleading comment in standalone IAM CreatePolicy The comment incorrectly stated that CreatePolicy only validates the policy document. In the standalone IAM server, CreatePolicy actually persists the policy via iama.s3ApiConfig.PutPolicies(). The changed flag is false because it doesn't modify s3cfg.Identities, not because nothing is stored. * Simplify IAM auth and add RequestId to responses - Remove redundant ACTION_ADMIN fallback in AuthIam: The action parameter in authRequest is for permission checking, not signature verification. If auth fails with ACTION_READ, it will fail with ACTION_ADMIN too. - Add SetRequestId() call before writing IAM responses for AWS compatibility. All IAM response structs embed iamCommonResponse which has SetRequestId(). * Address code review feedback for IAM implementation 1. auth_credentials.go: Add documentation warning that LookupByAccessKey returns internal pointers that should not be mutated. 2. iamapi_management_handlers.go & s3api_embedded_iam.go: Add input guards for StringWithCharset/iamStringWithCharset when length <= 0 or charset is empty to avoid runtime errors from rand.Int. 3. s3api_embedded_iam_test.go: Don't ignore xml.Marshal errors in test DoActions handler. Return proper error response if marshaling fails. 4. s3api_embedded_iam_test.go: Use obviously fake access key IDs (AKIATESTFAKEKEY*) to avoid CI secret scanner false positives. * Address code review feedback for IAM implementation (batch 2) 1. iamapi/iamapi_management_handlers.go: - Redact Authorization header log (security: avoid exposing signature) - Add nil-guard for iama.iam before LookupByAccessKey call 2. iamapi/iamapi_test.go: - Replace real-looking access keys with obviously fake ones (AKIATESTFAKEKEY*) to avoid CI secret scanner false positives 3. s3api/s3api_embedded_iam.go - CreateUser: - Validate UserName is not empty (return ErrCodeInvalidInputException) - Check for duplicate users (return ErrCodeEntityAlreadyExistsException) 4. s3api/s3api_embedded_iam.go - CreateAccessKey: - Return ErrCodeNoSuchEntityException if user doesn't exist - Removed implicit user creation behavior 5. s3api/s3api_embedded_iam.go - getActions: - Fix S3 ARN parsing for bucket/path patterns - Handle mybucket, mybucket/*, mybucket/path/* correctly - Return error if no valid actions found in policy 6. s3api/s3api_embedded_iam.go - handleImplicitUsername: - Redact Authorization header log - Add nil-guard for e.iam 7. s3api/s3api_embedded_iam.go - DoActions: - Reload in-memory IAM maps after credential mutations - Call LoadS3ApiConfigurationFromCredentialManager after save 8. s3api/auth_credentials.go - AuthSignatureOnly: - Add new signature-only authentication method - Bypasses S3 authorization checks for IAM operations - Used by AuthIam to properly separate signature verification from IAM-specific permission checks * Fix nil pointer dereference and error handling in IAM 1. AuthIam: Add nil check for identity after AuthSignatureOnly - AuthSignatureOnly can return nil identity with ErrNone for authTypePostPolicy or authTypeStreamingUnsigned - Now returns ErrAccessDenied if identity is nil 2. writeIamErrorResponse: Add missing error code cases - ErrCodeEntityAlreadyExistsException -> HTTP 409 Conflict - ErrCodeInvalidInputException -> HTTP 400 Bad Request 3. UpdateUser: Use consistent error handling - Changed from direct ErrInvalidRequest to writeIamErrorResponse - Now returns correct HTTP status codes based on error type * Add IAM config reload to standalone IAM server after mutations Match the behavior of embedded IAM (s3api_embedded_iam.go) by reloading the in-memory identity maps after persisting configuration changes. This ensures newly created access keys are visible to LookupByAccessKey immediately without requiring a server restart. * Minor improvements to test helpers and log masking 1. iamapi_test.go: Update mustMarshalJSON to use t.Helper() and t.Fatal() instead of panic() for better test diagnostics 2. s3api_embedded_iam.go: Mask access key in 'not found' log message to avoid exposing full access key IDs in logs * Mask access key in standalone IAM log message for consistency Match the embedded IAM version by masking the access key ID in the 'not found' log message (show only first 4 chars). |
