fix(s3): include static identities in listing operations (#8903)
* fix(s3): include static identities in listing operations Static identities loaded from -s3.config file were only stored in the S3 API server's in-memory state. Listing operations (s3.configure shell command, aws iam list-users) queried the credential manager which only returned dynamic identities from the backend store. Register static identities with the credential manager after loading so they are included in LoadConfiguration and ListUsers results, and filtered out before SaveConfiguration to avoid persisting them to the dynamic store. Fixes https://github.com/seaweedfs/seaweedfs/discussions/8896 * fix: avoid mutating caller's config and defensive copies - SaveConfiguration: use shallow struct copy instead of mutating the caller's config.Identities field - SetStaticIdentities: skip nil entries to avoid panics - GetStaticIdentities: defensively copy PolicyNames slice to avoid aliasing the original * fix: filter nil static identities and sync on config reload - SetStaticIdentities: filter nil entries from the stored slice (not just from staticNames) to prevent panics in LoadConfiguration/ListUsers - Extract updateCredentialManagerStaticIdentities helper and call it from both startup and the grace.OnReload handler so the credential manager's static snapshot stays current after config file reloads * fix: add mutex for static identity fields and fix ListUsers for store callers - Add sync.RWMutex to protect staticIdentities/staticNames against concurrent reads during config reload - Revert CredentialManager.ListUsers to return only store users, since internal callers (e.g. DeletePolicy) look up each user in the store and fail on non-existent static entries - Merge static usernames in the filer gRPC ListUsers handler instead, via the new GetStaticUsernames method - Fix CI: TestIAMPolicyManagement/managed_policy_crud_lifecycle was failing because DeletePolicy iterated static users that don't exist in the store * fix: show static identities in admin UI and weed shell The admin UI and weed shell s3.configure command query the filer's credential manager via gRPC, which is a separate instance from the S3 server's credential manager. Static identities were only registered on the S3 server's credential manager, so they never appeared in the filer's responses. - Add CredentialManager.LoadS3ConfigFile to parse a static S3 config file and register its identities - Add FilerOptions.s3ConfigFile so the filer can load the same static config that the S3 server uses - Wire s3ConfigFile through in weed mini and weed server modes - Merge static usernames in filer gRPC ListUsers handler - Add CredentialManager.GetStaticUsernames helper - Add sync.RWMutex to protect concurrent access to static identity fields - Avoid importing weed/filer from weed/credential (which pulled in filer store init() registrations and broke test isolation) - Add docker/compose/s3_static_users_example.json * fix(admin): make static users read-only in admin UI Static users loaded from the -s3.config file should not be editable or deletable through the admin UI since they are managed via the config file. - Add IsStatic field to ObjectStoreUser, set from credential manager - Hide edit, delete, and access key buttons for static users in the users table template - Show a "static" badge next to static user names - Return 403 Forbidden from UpdateUser and DeleteUser API handlers when the target user is a static identity * fix(admin): show details for static users GetObjectStoreUserDetails called credentialManager.GetUser which only queries the dynamic store. For static users this returned ErrUserNotFound. Fall back to GetStaticIdentity when the store lookup fails. * fix(admin): load static S3 identities in admin server The admin server has its own credential manager (gRPC store) which is a separate instance from the S3 server's and filer's. It had no static identity data, so IsStaticIdentity returned false (edit/delete buttons shown) and GetStaticIdentity returned nil (details page failed). Pass the -s3.config file path through to the admin server and call LoadS3ConfigFile on its credential manager, matching the approach used for the filer. * fix: use protobuf is_static field instead of passing config file path The previous approach passed -s3.config file path to every component (filer, admin). This is wrong because the admin server should not need to know about S3 config files. Instead, add an is_static field to the Identity protobuf message. The field is set when static identities are serialized (in GetStaticIdentities and LoadS3ConfigFile). Any gRPC client that loads configuration via GetConfiguration automatically sees which identities are static, without needing the config file. - Add is_static field (tag 8) to iam_pb.Identity proto message - Set IsStatic=true in GetStaticIdentities and LoadS3ConfigFile - Admin GetObjectStoreUsers reads identity.IsStatic from proto - Admin IsStaticUser helper loads config via gRPC to check the flag - Filer GetUser gRPC handler falls back to GetStaticIdentity - Remove s3ConfigFile from AdminOptions and NewAdminServer signature |

chore: remove ~50k lines of unreachable dead code (#8913)
* chore: remove unreachable dead code across the codebase Remove ~50,000 lines of unreachable code identified by static analysis. Major removals: - weed/filer/redis_lua: entire unused Redis Lua filer store implementation - weed/wdclient/net2, resource_pool: unused connection/resource pool packages - weed/plugin/worker/lifecycle: unused lifecycle plugin worker - weed/s3api: unused S3 policy templates, presigned URL IAM, streaming copy, multipart IAM, key rotation, and various SSE helper functions - weed/mq/kafka: unused partition mapping, compression, schema, and protocol functions - weed/mq/offset: unused SQL storage and migration code - weed/worker: unused registry, task, and monitoring functions - weed/query: unused SQL engine, parquet scanner, and type functions - weed/shell: unused EC proportional rebalance functions - weed/storage/erasure_coding/distribution: unused distribution analysis functions - Individual unreachable functions removed from 150+ files across admin, credential, filer, iam, kms, mount, mq, operation, pb, s3api, server, shell, storage, topology, and util packages * fix(s3): reset shared memory store in IAM test to prevent flaky failure TestLoadIAMManagerFromConfig_EmptyConfigWithFallbackKey was flaky because the MemoryStore credential backend is a singleton registered via init(). Earlier tests that create anonymous identities pollute the shared store, causing LookupAnonymous() to unexpectedly return true. Fix by calling Reset() on the memory store before the test runs. * style: run gofmt on changed files * fix: restore KMS functions used by integration tests * fix(plugin): prevent panic on send to closed worker session channel The Plugin.sendToWorker method could panic with "send on closed channel" when a worker disconnected while a message was being sent. The race was between streamSession.close() closing the outgoing channel and sendToWorker writing to it concurrently. Add a done channel to streamSession that is closed before the outgoing channel, and check it in sendToWorker's select to safely detect closed sessions without panicking. |

fix(s3): allow deleting the anonymous user from admin webui (#8706)
Remove the block that prevented deleting the "anonymous" identity and stop auto-creating it when absent. If no anonymous identity exists (or it is disabled), LookupAnonymous returns not-found and both auth paths return ErrAccessDenied for anonymous requests. To enable anonymous access, explicitly create the "anonymous" user. To revoke it, delete the user like any other identity. Closes #8694 |

iam: add IAM group management (#8560)
* iam: add Group message to protobuf schema Add Group message (name, members, policy_names, disabled) and add groups field to S3ApiConfiguration for IAM group management support (issue #7742). * iam: add group CRUD to CredentialStore interface and all backends Add group management methods (CreateGroup, GetGroup, DeleteGroup, ListGroups, UpdateGroup) to the CredentialStore interface with implementations for memory, filer_etc, postgres, and grpc stores. Wire group loading/saving into filer_etc LoadConfiguration and SaveConfiguration. * iam: add group IAM response types Add XML response types for group management IAM actions: CreateGroup, DeleteGroup, GetGroup, ListGroups, AddUserToGroup, RemoveUserFromGroup, AttachGroupPolicy, DetachGroupPolicy, ListAttachedGroupPolicies, ListGroupsForUser. * iam: add group management handlers to embedded IAM API Add CreateGroup, DeleteGroup, GetGroup, ListGroups, AddUserToGroup, RemoveUserFromGroup, AttachGroupPolicy, DetachGroupPolicy, ListAttachedGroupPolicies, and ListGroupsForUser handlers with dispatch in ExecuteAction. * iam: add group management handlers to standalone IAM API Add group handlers (CreateGroup, DeleteGroup, GetGroup, ListGroups, AddUserToGroup, RemoveUserFromGroup, AttachGroupPolicy, DetachGroupPolicy, ListAttachedGroupPolicies, ListGroupsForUser) and wire into DoActions dispatch. Also add helper functions for user/policy side effects. * iam: integrate group policies into authorization Add groups and userGroups reverse index to IdentityAccessManagement. Populate both maps during ReplaceS3ApiConfiguration and MergeS3ApiConfiguration. Modify evaluateIAMPolicies to evaluate policies from user's enabled groups in addition to user policies. Update VerifyActionPermission to consider group policies when checking hasAttachedPolicies. * iam: add group side effects on user deletion and rename When a user is deleted, remove them from all groups they belong to. When a user is renamed, update group membership references. Applied to both embedded and standalone IAM handlers. * iam: watch /etc/iam/groups directory for config changes Add groups directory to the filer subscription watcher so group file changes trigger IAM configuration reloads. * admin: add group management page to admin UI Add groups page with CRUD operations, member management, policy attachment, and enable/disable toggle. Register routes in admin handlers and add Groups entry to sidebar navigation. * test: add IAM group management integration tests Add comprehensive integration tests for group CRUD, membership, policy attachment, policy enforcement, disabled group behavior, user deletion side effects, and multi-group membership. Add "group" test type to CI matrix in s3-iam-tests workflow. * iam: address PR review comments for group management - Fix XSS vulnerability in groups.templ: replace innerHTML string concatenation with DOM APIs (createElement/textContent) for rendering member and policy lists - Use userGroups reverse index in embedded IAM ListGroupsForUser for O(1) lookup instead of iterating all groups - Add buildUserGroupsIndex helper in standalone IAM handlers; use it in ListGroupsForUser and removeUserFromAllGroups for efficient lookup - Add note about gRPC store load-modify-save race condition limitation * iam: add defensive copies, validation, and XSS fixes for group management - Memory store: clone groups on store/retrieve to prevent mutation - Admin dash: deep copy groups before mutation, validate user/policy exists - HTTP handlers: translate credential errors to proper HTTP status codes, use *bool for Enabled field to distinguish missing vs false - Groups templ: use data attributes + event delegation instead of inline onclick for XSS safety, prevent stale async responses * iam: add explicit group methods to PropagatingCredentialStore Add CreateGroup, GetGroup, DeleteGroup, ListGroups, and UpdateGroup methods instead of relying on embedded interface fallthrough. Group changes propagate via filer subscription so no RPC propagation needed. * iam: detect postgres unique constraint violation and add groups index Return ErrGroupAlreadyExists when INSERT hits SQLState 23505 instead of a generic error. Add index on groups(disabled) for filtered queries. * iam: add Marker field to group list response types Add Marker string field to GetGroupResult, ListGroupsResult, ListAttachedGroupPoliciesResult, and ListGroupsForUserResult to match AWS IAM pagination response format. * iam: check group attachment before policy deletion Reject DeletePolicy if the policy is attached to any group, matching AWS IAM behavior. Add PolicyArn to ListAttachedGroupPolicies response. * iam: include group policies in IAM authorization Merge policy names from user's enabled groups into the IAMIdentity used for authorization, so group-attached policies are evaluated alongside user-attached policies. * iam: check for name collision before renaming user in UpdateUser Scan identities and inline policies for newUserName before mutating, returning EntityAlreadyExists if a collision is found. Reuse the already-loaded policies instead of loading them again inside the loop. * test: use t.Cleanup for bucket cleanup in group policy test * iam: wrap ErrUserNotInGroup sentinel in RemoveGroupMember error Wrap credential.ErrUserNotInGroup so errors.Is works in groupErrorToHTTPStatus, returning proper 400 instead of 500. * admin: regenerate groups_templ.go with XSS-safe data attributes Regenerated from groups.templ which uses data-group-name attributes instead of inline onclick with string interpolation. * iam: add input validation and persist groups during migration - Validate nil/empty group name in CreateGroup and UpdateGroup - Save groups in migrateToMultiFile so they survive legacy migration * admin: use groupErrorToHTTPStatus in GetGroupMembers and GetGroupPolicies * iam: short-circuit UpdateUser when newUserName equals current name * iam: require empty PolicyNames before group deletion Reject DeleteGroup when group has attached policies, matching the existing members check. Also fix GetGroup error handling in DeletePolicy to only skip ErrGroupNotFound, not all errors. * ci: add weed/pb/** to S3 IAM test trigger paths * test: replace time.Sleep with require.Eventually for propagation waits Use polling with timeout instead of fixed sleeps to reduce flakiness in integration tests waiting for IAM policy propagation. * fix: use credentialManager.GetPolicy for AttachGroupPolicy validation Policies created via CreatePolicy through credentialManager are stored in the credential store, not in s3cfg.Policies (which only has static config policies). Change AttachGroupPolicy to use credentialManager.GetPolicy() for policy existence validation. * feat: add UpdateGroup handler to embedded IAM API Add UpdateGroup action to enable/disable groups and rename groups via the IAM API. This is a SeaweedFS extension (not in AWS SDK) used by tests to toggle group disabled status. * fix: authenticate raw IAM API calls in group tests The embedded IAM endpoint rejects anonymous requests. Replace callIAMAPI with callIAMAPIAuthenticated that uses JWT bearer token authentication via the test framework. * feat: add UpdateGroup handler to standalone IAM API Mirror the embedded IAM UpdateGroup handler in the standalone IAM API for parity. * fix: add omitempty to Marker XML tags in group responses Non-truncated responses should not emit an empty <Marker/> element. * fix: distinguish backend errors from missing policies in AttachGroupPolicy Return ServiceFailure for credential manager errors instead of masking them as NoSuchEntity. Also switch ListGroupsForUser to use s3cfg.Groups instead of in-memory reverse index to avoid stale data. Add duplicate name check to UpdateGroup rename. * fix: standalone IAM AttachGroupPolicy uses persisted policy store Check managed policies from GetPolicies() instead of s3cfg.Policies so dynamically created policies are found. Also add duplicate name check to UpdateGroup rename. * fix: rollback inline policies on UpdateUser PutPolicies failure If PutPolicies fails after moving inline policies to the new username, restore both the identity name and the inline policies map to their original state to avoid a partial-write window. * fix: correct test cleanup ordering for group tests Replace scattered defers with single ordered t.Cleanup in each test to ensure resources are torn down in reverse-creation order: remove membership, detach policies, delete access keys, delete users, delete groups, delete policies. Move bucket cleanup to parent test scope and delete objects before bucket. * fix: move identity nil check before map lookup and refine hasAttachedPolicies Move the nil check on identity before accessing identity.Name to prevent panic. Also refine hasAttachedPolicies to only consider groups that are enabled and have actual policies attached, so membership in a no-policy group doesn't incorrectly trigger IAM authorization. * fix: fail group reload on unreadable or corrupt group files Return errors instead of logging and continuing when group files cannot be read or unmarshaled. This prevents silently applying a partial IAM config with missing group memberships or policies. * fix: use errors.Is for sql.ErrNoRows comparison in postgres group store * docs: explain why group methods skip propagateChange Group changes propagate to S3 servers via filer subscription (watching /etc/iam/groups/) rather than gRPC RPCs, since there are no group-specific RPCs in the S3 cache protocol. * fix: remove unused policyNameFromArn and strings import * fix: update service account ParentUser on user rename When renaming a user via UpdateUser, also update ParentUser references in service accounts to prevent them from becoming orphaned after the next configuration reload. * fix: wrap DetachGroupPolicy error with ErrPolicyNotAttached sentinel Use credential.ErrPolicyNotAttached so groupErrorToHTTPStatus maps it to 400 instead of falling back to 500. * fix: use admin S3 client for bucket cleanup in enforcement test The user S3 client may lack permissions by cleanup time since the user is removed from the group in an earlier subtest. Use the admin S3 client to ensure bucket and object cleanup always succeeds. * fix: add nil guard for group param in propagating store log calls Prevent potential nil dereference when logging group.Name in CreateGroup and UpdateGroup of PropagatingCredentialStore. * fix: validate Disabled field in UpdateGroup handlers Reject values other than "true" or "false" with InvalidInputException instead of silently treating them as false. * fix: seed mergedGroups from existing groups in MergeS3ApiConfiguration Previously the merge started with empty group maps, dropping any static-file groups. Now seeds from existing iam.groups before overlaying dynamic config, and builds the reverse index after merging to avoid stale entries from overridden groups. * fix: use errors.Is for filer_pb.ErrNotFound comparison in group loading Replace direct equality (==) with errors.Is() to correctly match wrapped errors, consistent with the rest of the codebase. * fix: add ErrUserNotFound and ErrPolicyNotFound to groupErrorToHTTPStatus Map these sentinel errors to 404 so AddGroupMember and AttachGroupPolicy return proper HTTP status codes. * fix: log cleanup errors in group integration tests Replace fire-and-forget cleanup calls with error-checked versions that log failures via t.Logf for debugging visibility. * fix: prevent duplicate group test runs in CI matrix The basic lane's -run "TestIAM" regex also matched TestIAMGroup* tests, causing them to run in both the basic and group lanes. Replace with explicit test function names. * fix: add GIN index on groups.members JSONB for membership lookups Without this index, ListGroupsForUser and membership queries require full table scans on the groups table. * fix: handle cross-directory moves in IAM config subscription When a file is moved out of an IAM directory (e.g., /etc/iam/groups), the dir variable was overwritten with NewParentPath, causing the source directory change to be missed. Now also notifies handlers about the source directory for cross-directory moves. * fix: validate members/policies before deleting group in admin handler AdminServer.DeleteGroup now checks for attached members and policies before delegating to credentialManager, matching the IAM handler guards. * fix: merge groups by name instead of blind append during filer load Match the identity loader's merge behavior: find existing group by name and replace, only append when no match exists. Prevents duplicates when legacy and multi-file configs overlap. * fix: check DeleteEntry response error when cleaning obsolete group files Capture and log resp.Error from filer DeleteEntry calls during group file cleanup, matching the pattern used in deleteGroupFile. * fix: verify source user exists before no-op check in UpdateUser Reorder UpdateUser to find the source identity first and return NoSuchEntityException if not found, before checking if the rename is a no-op. Previously a non-existent user renamed to itself would incorrectly return success. * fix: update service account parent refs on user rename in embedded IAM The embedded IAM UpdateUser handler updated group membership but not service account ParentUser fields, unlike the standalone handler. * fix: replay source-side events for all handlers on cross-dir moves Pass nil newEntry to bucket, IAM, and circuit-breaker handlers for the source directory during cross-directory moves, so all watchers can clear caches for the moved-away resource. * fix: don't seed mergedGroups from existing iam.groups in merge Groups are always dynamic (from filer), never static (from s3.config). Seeding from iam.groups caused stale deleted groups to persist. Now only uses config.Groups from the dynamic filer config. * fix: add deferred user cleanup in TestIAMGroupUserDeletionSideEffect Register t.Cleanup for the created user so it gets cleaned up even if the test fails before the inline DeleteUser call. * fix: assert UpdateGroup HTTP status in disabled group tests Add require.Equal checks for 200 status after UpdateGroup calls so the test fails immediately on API errors rather than relying on the subsequent Eventually timeout. * fix: trim whitespace from group name in filer store operations Trim leading/trailing whitespace from group.Name before validation in CreateGroup and UpdateGroup to prevent whitespace-only filenames. Also merge groups by name during multi-file load to prevent duplicates. * fix: add nil/empty group validation in gRPC store Guard CreateGroup and UpdateGroup against nil group or empty name to prevent panics and invalid persistence. * fix: add nil/empty group validation in postgres store Guard CreateGroup and UpdateGroup against nil group or empty name to prevent panics from nil member access and empty-name row inserts. * fix: add name collision check in embedded IAM UpdateUser The embedded IAM handler renamed users without checking if the target name already existed, unlike the standalone handler. * fix: add ErrGroupNotEmpty sentinel and map to HTTP 409 AdminServer.DeleteGroup now wraps conflict errors with ErrGroupNotEmpty, and groupErrorToHTTPStatus maps it to 409 Conflict instead of 500. * fix: use appropriate error message in GetGroupDetails based on status Return "Group not found" only for 404, use "Failed to retrieve group" for other error statuses instead of always saying "Group not found". * fix: use backend-normalized group.Name in CreateGroup response After credentialManager.CreateGroup may normalize the name (e.g., trim whitespace), use group.Name instead of the raw input for the returned GroupData to ensure consistency. * fix: add nil/empty group validation in memory store Guard CreateGroup and UpdateGroup against nil group or empty name to prevent panics from nil pointer dereference on map access. * fix: reorder embedded IAM UpdateUser to verify source first Find the source identity before checking for collisions, matching the standalone handler's logic. Previously a non-existent user renamed to an existing name would get EntityAlreadyExists instead of NoSuchEntity. * fix: handle same-directory renames in metadata subscription Replay a delete event for the old entry name during same-directory renames so handlers like onBucketMetadataChange can clean up stale state for the old name. * fix: abort GetGroups on non-ErrGroupNotFound errors Only skip groups that return ErrGroupNotFound. Other errors (e.g., transient backend failures) now abort the handler and return the error to the caller instead of silently producing partial results. * fix: add aria-label and title to icon-only group action buttons Add accessible labels to View and Delete buttons so screen readers and tooltips provide meaningful context. * fix: validate group name in saveGroup to prevent invalid filenames Trim whitespace and reject empty names before writing group JSON files, preventing creation of files like ".json". * fix: add /etc/iam/groups to filer subscription watched directories The groups directory was missing from the watched directories list, so S3 servers in a cluster would not detect group changes made by other servers via filer. The onIamConfigChange handler already had code to handle group directory changes but it was never triggered. * add direct gRPC propagation for group changes to S3 servers Groups now have the same dual propagation as identities and policies: direct gRPC push via propagateChange + async filer subscription. - Add PutGroup/RemoveGroup proto messages and RPCs - Add PutGroup/RemoveGroup in-memory cache methods on IAM - Add PutGroup/RemoveGroup gRPC server handlers - Update PropagatingCredentialStore to call propagateChange on group mutations * reduce log verbosity for config load summary Change ReplaceS3ApiConfiguration log from Infof to V(1).Infof to avoid noisy output on every config reload. * admin: show user groups in view and edit user modals - Add Groups field to UserDetails and populate from credential manager - Show groups as badges in user details view modal - Add group management to edit user modal: display current groups, add to group via dropdown, remove from group via badge x button * fix: remove duplicate showAlert that broke modal-alerts.js admin.js defined showAlert(type, message) which overwrote the modal-alerts.js version showAlert(message, type), causing broken unstyled alert boxes. Remove the duplicate and swap all callers in admin.js to use the correct (message, type) argument order. * fix: unwrap groups API response in edit user modal The /api/groups endpoint returns {"groups": [...]}, not a bare array. * Update object_store_users_templ.go * test: assert AccessDenied error code in group denial tests Replace plain assert.Error checks with awserr.Error type assertion and AccessDenied code verification, matching the pattern used in other IAM integration tests. * fix: propagate GetGroups errors in ShowGroups handler getGroupsPageData was swallowing errors and returning an empty page with 200 status. Now returns the error so ShowGroups can respond with a proper error status. * fix: reject AttachGroupPolicy when credential manager is nil Previously skipped policy existence validation when credentialManager was nil, allowing attachment of nonexistent policies. Now returns a ServiceFailureException error. * fix: preserve groups during partial MergeS3ApiConfiguration updates UpsertIdentity calls MergeS3ApiConfiguration with a partial config containing only the updated identity (nil Groups). This was wiping all in-memory group state. Now only replaces groups when config.Groups is non-nil (full config reload). * fix: propagate errors from group lookup in GetObjectStoreUserDetails ListGroups and GetGroup errors were silently ignored, potentially showing incomplete group data in the UI. * fix: use DOM APIs for group badge remove button to prevent XSS Replace innerHTML with onclick string interpolation with DOM createElement + addEventListener pattern. Also add aria-label and title to the add-to-group button. * fix: snapshot group policies under RLock to prevent concurrent map access evaluateIAMPolicies was copying the map reference via groupMap := iam.groups under RLock then iterating after RUnlock, while PutGroup mutates the map in-place. Now copies the needed policy names into a slice while holding the lock. * fix: add nil IAM check to PutGroup and RemoveGroup gRPC handlers Match the nil guard pattern used by PutPolicy/DeletePolicy to prevent nil pointer dereference when IAM is not initialized. |

s3api: cache parsed IAM policy engines for fallback auth
Previously, evaluateIAMPolicies created a new PolicyEngine and re-parsed the JSON policy document for every policy on every request. This adds a shared iamPolicyEngine field that caches compiled policies, kept in sync by PutPolicy, DeletePolicy, and bulk config reload paths. - PutPolicy deletes the old cache entry before setting the new one, so a parse failure on update does not leave a stale allow. - Log warnings when policy compilation fails instead of silently discarding errors. - Add test for valid-to-invalid policy update regression. |

Fix S3 signature verification behind reverse proxies (#8444)
* Fix S3 signature verification behind reverse proxies When SeaweedFS is deployed behind a reverse proxy (e.g. nginx, Kong, Traefik), AWS S3 Signature V4 verification fails because the Host header the client signed with (e.g. "localhost:9000") differs from the Host header SeaweedFS receives on the backend (e.g. "seaweedfs:8333"). This commit adds a new -s3.externalUrl parameter (and S3_EXTERNAL_URL environment variable) that tells SeaweedFS what public-facing URL clients use to connect. When set, SeaweedFS uses this host value for signature verification instead of the Host header from the incoming request. New parameter: -s3.externalUrl (flag) or S3_EXTERNAL_URL (environment variable) Example: -s3.externalUrl=http://localhost:9000 Example: S3_EXTERNAL_URL=https://s3.example.com The environment variable is particularly useful in Docker/Kubernetes deployments where the external URL is injected via container config. The flag takes precedence over the environment variable when both are set. At startup, the URL is parsed and default ports are stripped to match AWS SDK behavior (port 80 for HTTP, port 443 for HTTPS), so "http://s3.example.com:80" and "http://s3.example.com" are equivalent. Bugs fixed: - Default port stripping was removed by a prior PR, causing signature mismatches when clients connect on standard ports (80/443) - X-Forwarded-Port was ignored when X-Forwarded-Host was not present - Scheme detection now uses proper precedence: X-Forwarded-Proto > TLS connection > URL scheme > "http" - Test expectations for standard port stripping were incorrect - expectedHost field in TestSignatureV4WithForwardedPort was declared but never actually checked (self-referential test) * Add Docker integration test for S3 proxy signature verification Docker Compose setup with nginx reverse proxy to validate that the -s3.externalUrl parameter (or S3_EXTERNAL_URL env var) correctly resolves S3 signature verification when SeaweedFS runs behind a proxy. The test uses nginx proxying port 9000 to SeaweedFS on port 8333, with X-Forwarded-Host/Port/Proto headers set. SeaweedFS is configured with -s3.externalUrl=http://localhost:9000 so it uses "localhost:9000" for signature verification, matching what the AWS CLI signs with. The test can be run with aws CLI on the host or without it by using the amazon/aws-cli Docker image with --network host. Test covers: create-bucket, list-buckets, put-object, head-object, list-objects-v2, get-object, content round-trip integrity, delete-object, and delete-bucket — all through the reverse proxy. * Create s3-proxy-signature-tests.yml * fix CLI * fix CI * Update s3-proxy-signature-tests.yml * address comments * Update Dockerfile * add user * no need for fuse * Update s3-proxy-signature-tests.yml * debug * weed mini * fix health check * health check * fix health checking --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: Chris Lu <chris.lu@gmail.com> |

S3: Implement IAM defaults and STS signing key fallback (#8348)
* S3: Implement IAM defaults and STS signing key fallback logic * S3: Refactor startup order to init SSE-S3 key manager before IAM * S3: Derive STS signing key from KEK using HKDF for security isolation * S3: Document STS signing key fallback in security.toml * fix(s3api): refine anonymous access logic and secure-by-default behavior - Initialize anonymous identity by default in `NewIdentityAccessManagement` to prevent nil pointer exceptions. - Ensure `ReplaceS3ApiConfiguration` preserves the anonymous identity if not present in the new configuration. - Update `NewIdentityAccessManagement` signature to accept `filerClient`. - In legacy mode (no policy engine), anonymous defaults to Deny (no actions), preserving secure-by-default behavior. - Use specific `LookupAnonymous` method instead of generic map lookup. - Update tests to accommodate signature changes and verify improved anonymous handling. * feat(s3api): make IAM configuration optional - Start S3 API server without a configuration file if `EnableIam` option is set. - Default to `Allow` effect for policy engine when no configuration is provided (Zero-Config mode). - Handle empty configuration path gracefully in `loadIAMManagerFromConfig`. - Add integration test `iam_optional_test.go` to verify empty config behavior. * fix(iamapi): fix signature mismatch in NewIdentityAccessManagementWithStore * fix(iamapi): properly initialize FilerClient instead of passing nil * fix(iamapi): properly initialize filer client for IAM management - Instead of passing `nil`, construct a `wdclient.FilerClient` using the provided `Filers` addresses. - Ensure `NewIdentityAccessManagementWithStore` receives a valid `filerClient` to avoid potential nil pointer dereferences or limited functionality. * clean: remove dead code in s3api_server.go * refactor(s3api): improve IAM initialization, safety and anonymous access security * fix(s3api): ensure IAM config loads from filer after client init * fix(s3): resolve test failures in integration, CORS, and tagging tests - Fix CORS tests by providing explicit anonymous permissions config - Fix S3 integration tests by setting admin credentials in init - Align tagging test credentials in CI with IAM defaults - Added goroutine to retry IAM config load in iamapi server * fix(s3): allow anonymous access to health targets and S3 Tables when identities are present * fix(ci): use /healthz for Caddy health check in awscli tests * iam, s3api: expose DefaultAllow from IAM and Policy Engine This allows checking the global "Open by Default" configuration from other components like S3 Tables. * s3api/s3tables: support DefaultAllow in permission logic and handler Updated CheckPermissionWithContext to respect the DefaultAllow flag in PolicyContext. This enables "Open by Default" behavior for unauthenticated access in zero-config environments. Added a targeted unit test to verify the logic. * s3api/s3tables: propagate DefaultAllow through handlers Propagated the DefaultAllow flag to individual handlers for namespaces, buckets, tables, policies, and tagging. This ensures consistent "Open by Default" behavior across all S3 Tables API endpoints. * s3api: wire up DefaultAllow for S3 Tables API initialization Updated registerS3TablesRoutes to query the global IAM configuration and set the DefaultAllow flag on the S3 Tables API server. This completes the end-to-end propagation required for anonymous access in zero-config environments. Added a SetDefaultAllow method to S3TablesApiServer to facilitate this. * s3api: fix tests by adding DefaultAllow to mock IAM integrations The IAMIntegration interface was updated to include DefaultAllow(), breaking several mock implementations in tests. This commit fixes the build errors by adding the missing method to the mocks. * env * ensure ports * env * env * fix default allow * add one more test using non-anonymous user * debug * add more debug * less logs |

test: add Trino Iceberg catalog integration test (#8228)
* test: add Trino Iceberg catalog integration test - Create test/s3/catalog_trino/trino_catalog_test.go with TestTrinoIcebergCatalog - Tests integration between Trino SQL engine and SeaweedFS Iceberg REST catalog - Starts weed mini with all services and Trino in Docker container - Validates Iceberg catalog schema creation and listing operations - Uses native S3 filesystem support in Trino with path-style access - Add workflow job to s3-tables-tests.yml for CI execution * fix: preserve AWS environment credentials when replacing S3 configuration When S3 configuration is loaded from filer/db, it replaces the identities list and inadvertently removes AWS_ACCESS_KEY_ID credentials that were added from environment variables. This caused auth to remain disabled even though valid credentials were present. Fix by preserving environment-based identities when replacing the configuration and re-adding them after the replacement. This ensures environment credentials persist across configuration reloads and properly enable authentication. * fix: use correct ServerAddress format with gRPC port encoding The admin server couldn't connect to master because the master address was missing the gRPC port information. Use pb.NewServerAddress() which properly encodes both HTTP and gRPC ports in the address string. Changes: - weed/command/mini.go: Use pb.NewServerAddress for master address in admin - test/s3/policy/policy_test.go: Store and use gRPC ports for master/filer addresses This fix applies to: 1. Admin server connection to master (mini.go) 2. Test shell commands that need master/filer addresses (policy_test.go) * move * move * fix: always include gRPC port in server address encoding The NewServerAddress() function was omitting the gRPC port from the address string when it matched the port+10000 convention. However, gRPC port allocation doesn't always follow this convention - when the calculated port is busy, an alternative port is allocated. This caused a bug where: 1. Master's gRPC port was allocated as 50661 (sequential, not port+10000) 2. Address was encoded as '192.168.1.66:50660' (gRPC port omitted) 3. Admin client called ToGrpcAddress() which assumed port+10000 offset 4. Admin tried to connect to 60660 but master was on 50661 → connection failed Fix: Always include explicit gRPC port in address format (host:httpPort.grpcPort) unless gRPC port is 0. This makes addresses unambiguous and works regardless of the port allocation strategy used. Impacts: All server-to-server gRPC connections now use properly formatted addresses. * test: fix Iceberg REST API readiness check The Iceberg REST API endpoints require authentication. When checked without credentials, the API returns 403 Forbidden (not 401 Unauthorized). The readiness check now accepts both auth error codes (401/403) as indicators that the service is up and ready, it just needs credentials. This fixes the 'Iceberg REST API did not become ready' test failure. * Fix AWS SigV4 signature verification for base64-encoded payload hashes AWS SigV4 canonical requests must use hex-encoded SHA256 hashes, but the X-Amz-Content-Sha256 header may be transmitted as base64. Changes: - Added normalizePayloadHash() function to convert base64 to hex - Call normalizePayloadHash() in extractV4AuthInfoFromHeader() - Added encoding/base64 import Fixes 403 Forbidden errors on POST requests to Iceberg REST API when clients send base64-encoded content hashes in the header.

fix: IAM authentication with AWS Signature V4 and environment credentials (#8099)
* fix: IAM authentication with AWS Signature V4 and environment credentials Three key fixes for authenticated IAM requests to work: 1. Fix request body consumption before signature verification - iamMatcher was calling r.ParseForm() which consumed POST body - This broke AWS Signature V4 verification on subsequent reads - Now only check query string in matcher, preserving body for verification - File: weed/s3api/s3api_server.go 2. Preserve environment variable credentials across config reloads - After IAM mutations, config reload overwrote env var credentials - Extract env var loading into loadEnvironmentVariableCredentials() - Call after every config reload to persist credentials - File: weed/s3api/auth_credentials.go 3. Add authenticated IAM tests and test infrastructure - New TestIAMAuthenticated suite with AWS SDK + Signature V4 - Dynamic port allocation for independent test execution - Flag reset to prevent state leakage between tests - CI workflow to run S3 and IAM tests separately - Files: test/s3/example/*, .github/workflows/s3-example-integration-tests.yml All tests pass: - TestIAMCreateUser (unauthenticated) - TestIAMAuthenticated (with AWS Signature V4) - S3 integration tests * fmt * chore: rename test/s3/example to test/s3/normal * simplify: CI runs all integration tests in single job * Update s3-example-integration-tests.yml * ci: run each test group separately to avoid raft registry conflicts |

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

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

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. |

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. |

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`. |

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. |

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 |

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. |

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 |

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

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 |

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(). Fixes #7912 * add AuthPostPolicy * refactor * Optimizing Auth Credentials * Update auth_credentials.go * Update auth_credentials.go |

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. |

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). |

s3: allow -s3.config and -s3.iam.config to work together (#7727)
When both -s3.config and -s3.iam.config are configured, traditional credentials from -s3.config were failing with Access Denied because the authorization code always used IAM authorization when IAM integration was configured. The fix checks if the identity has legacy Actions (from -s3.config). If so, use the legacy canDo() authorization. Only use IAM authorization for JWT/STS identities that don't have legacy Actions. This allows both configuration options to coexist: - Traditional credentials use legacy authorization - JWT/STS credentials use IAM authorization Fixes #7720 |

s3: enable auth when IAM integration is configured (#7726)
When only IAM integration is configured (via -s3.iam.config) without traditional S3 identities, the isAuthEnabled flag was not being set, causing the Auth middleware to bypass all authentication checks. This fix ensures that when SetIAMIntegration is called with a non-nil integration, isAuthEnabled is set to true, properly enforcing authentication for all requests. Added negative authentication tests: - TestS3AuthenticationDenied: tests rejection of unauthenticated, invalid, and expired JWT requests - TestS3IAMOnlyModeRejectsAnonymous: tests that IAM-only mode properly rejects anonymous requests Fixes #7724 |

s3: add s3:ExistingObjectTag condition support for bucket policies (#7677)
* s3: add s3:ExistingObjectTag condition support in policy engine
Add support for s3:ExistingObjectTag/<tag-key> condition keys in bucket
policies, allowing access control based on object tags.
Changes:
- Add ObjectEntry field to PolicyEvaluationArgs (entry.Extended metadata)
- Update EvaluateConditions to handle s3:ExistingObjectTag/<key> format
- Extract tag value from entry metadata using X-Amz-Tagging-<key> prefix
This enables policies like:
{
"Condition": {
"StringEquals": {
"s3:ExistingObjectTag/status": ["public"]
}
}
}
Fixes: https://github.com/seaweedfs/seaweedfs/issues/7447
* s3: update EvaluatePolicy to accept object entry for tag conditions
Update BucketPolicyEngine.EvaluatePolicy to accept objectEntry parameter
(entry.Extended metadata) for evaluating tag-based policy conditions.
Changes:
- Add objectEntry parameter to EvaluatePolicy method
- Update callers in auth_credentials.go and s3api_bucket_handlers.go
- Pass nil for objectEntry in auth layer (entry fetched later in handlers)
For tag-based conditions to work, handlers should call EvaluatePolicy
with the object's entry.Extended after fetching the entry from filer.
* s3: add tests for s3:ExistingObjectTag policy conditions
Add comprehensive tests for object tag-based policy conditions:
- TestExistingObjectTagCondition: Basic tag matching scenarios
- Matching/non-matching tag values
- Missing tags, no tags, empty tags
- Multiple tags with one matching
- TestExistingObjectTagConditionMultipleTags: Multiple tag conditions
- Both tags match
- Only one tag matches
- TestExistingObjectTagDenyPolicy: Deny policies with tag conditions
- Default allow without tag
- Deny when specific tag present
* s3: document s3:ExistingObjectTag support and feature status
Update policy engine documentation:
- Add s3:ExistingObjectTag/<tag-key> to supported condition keys
- Add 'Object Tag-Based Access Control' section with examples
- Add 'Feature Status' section with implemented and planned features
Planned features for future implementation:
- s3:RequestObjectTag/<key>
- s3:RequestObjectTagKeys
- s3:x-amz-server-side-encryption
- Cross-account access
* Implement tag-based policy re-check in handlers
- Add checkPolicyWithEntry helper to S3ApiServer for handlers to re-check
policy after fetching object entry (for s3:ExistingObjectTag conditions)
- Add HasPolicyForBucket method to policy engine for efficient check
- Integrate policy re-check in GetObjectHandler after entry is fetched
- Integrate policy re-check in HeadObjectHandler after entry is fetched
- Update auth_credentials.go comments to explain two-phase evaluation
- Update documentation with supported operations for tag-based conditions
This implements 'Approach 1' where handlers re-check the policy with
the object entry after fetching it, allowing tag-based conditions to
be properly evaluated.
* Add integration tests for s3:ExistingObjectTag conditions
- Add TestCheckPolicyWithEntry: tests checkPolicyWithEntry helper with various
tag scenarios (matching tags, non-matching tags, empty entry, nil entry)
- Add TestCheckPolicyWithEntryNoPolicyForBucket: tests early return when no policy
- Add TestCheckPolicyWithEntryNilPolicyEngine: tests nil engine handling
- Add TestCheckPolicyWithEntryDenyPolicy: tests deny policies with tag conditions
- Add TestHasPolicyForBucket: tests HasPolicyForBucket method
These tests cover the Phase 2 policy evaluation with object entry metadata,
ensuring tag-based conditions are properly evaluated.
* Address code review nitpicks
- Remove unused extractObjectTags placeholder function (engine.go)
- Add clarifying comment about s3:ExistingObjectTag/<key> evaluation
- Consolidate duplicate tag-based examples in README
- Factor out tagsToEntry helper to package level in tests
* Address code review feedback
- Fix unsafe type assertions in GetObjectHandler and HeadObjectHandler
when getting identity from context (properly handle type assertion failure)
- Extract getConditionContextValue helper to eliminate duplicated logic
between EvaluateConditions and EvaluateConditionsLegacy
- Ensure consistent handling of missing condition keys (always return
empty slice)
* Fix GetObjectHandler to match HeadObjectHandler pattern
Add safety check for nil objectEntryForSSE before tag-based policy
evaluation, ensuring tag-based conditions are always evaluated rather
than silently skipped if entry is unexpectedly nil.
Addresses review comment from Copilot.
* Fix HeadObject action name in docs for consistency
Change 'HeadObject' to 's3:HeadObject' to match other action names.
* Extract recheckPolicyWithObjectEntry helper to reduce duplication
Move the repeated identity extraction and policy re-check logic from
GetObjectHandler and HeadObjectHandler into a shared helper method.
* Add validation for empty tag key in s3:ExistingObjectTag condition
Prevent potential issues with malformed policies containing
s3:ExistingObjectTag/ (empty tag key after slash).

s3: fix ListBuckets not showing buckets created by authenticated users (#7648)
* s3: fix ListBuckets not showing buckets created by authenticated users Fixes #7647 ## Problem Users with proper Admin permissions could create buckets but couldn't list them. The issue occurred because ListBucketsHandler was not wrapped with the Auth middleware, so the authenticated identity was never set in the request context. ## Root Cause - PutBucketHandler uses iam.Auth() middleware which sets identity in context - ListBucketsHandler did NOT use iam.Auth() middleware - Without the middleware, GetIdentityNameFromContext() returned empty string - Bucket ownership checks failed because no identity was present ## Changes 1. Wrap ListBucketsHandler with iam.Auth() middleware (s3api_server.go) 2. Update ListBucketsHandler to get identity from context (s3api_bucket_handlers.go) 3. Add lookupByIdentityName() helper method (auth_credentials.go) 4. Add comprehensive test TestListBucketsIssue7647 (s3api_bucket_handlers_test.go) ## Testing - All existing tests pass (1348 tests in s3api package) - New test TestListBucketsIssue7647 validates the fix - Verified admin users can see their created buckets - Verified admin users can see all buckets - Verified backward compatibility maintained * s3: fix ListBuckets for JWT/Keycloak authentication The previous fix broke JWT/Keycloak authentication because JWT identities are created on-the-fly and not stored in the iam.identities list. The lookupByIdentityName() would return nil for JWT users. Solution: Store the full Identity object in the request context, not just the name. This allows ListBucketsHandler to retrieve the complete identity for all authentication types (SigV2, SigV4, JWT, Anonymous). Changes: - Add SetIdentityInContext/GetIdentityFromContext in s3_constants/header.go - Update Auth middleware to store full identity in context - Update ListBucketsHandler to retrieve identity from context first, with fallback to lookup for backward compatibility * s3: optimize lookupByIdentityName to O(1) using map Address code review feedback: Use a map for O(1) lookups instead of O(N) linear scan through identities list. Changes: - Add nameToIdentity map to IdentityAccessManagement struct - Populate map in loadS3ApiConfiguration (consistent with accessKeyIdent pattern) - Update lookupByIdentityName to use map lookup instead of loop This improves performance when many identities are configured and aligns with the existing pattern used for accessKeyIdent lookups. * s3: address code review feedback on nameToIdentity and logging Address two code review points: 1. Wire nameToIdentity into env-var fallback path - The AWS env-var fallback in NewIdentityAccessManagementWithStore now populates nameToIdentity map along with accessKeyIdent - Keeps all identity lookup maps in sync - Avoids potential issues if handlers rely on lookupByIdentityName 2. Improve access key lookup logging - Reduce log verbosity: V(1) -> V(2) for failed lookups - Truncate access keys in logs (show first 4 chars + ***) - Include key length for debugging - Prevents credential exposure in production logs - Reduces log noise from misconfigured clients * fmt * s3: refactor truncation logic and improve error handling Address additional code review feedback: 1. DRY principle: Extract key truncation logic into local function - Define truncate() helper at function start - Reuse throughout lookupByAccessKey - Eliminates code duplication 2. Enhanced security: Mask very short access keys - Keys <= 4 chars now show as '***' instead of full key - Prevents any credential exposure even for short keys - Consistent masking across all log statements 3. Improved robustness: Add warning log for type assertion failure - Log unexpected type when identity context object is wrong type - Helps debug potential middleware or context issues - Better production diagnostics 4. Documentation: Add comment about future optimization opportunity - Note potential for lightweight identity view in context - Suggests credential-free view for better data minimization - Documents design decision for future maintainers |

Support multiple filers for S3 and IAM servers with automatic failover (#7550)
* Support multiple filers for S3 and IAM servers with automatic failover
This change adds support for multiple filer addresses in the 'weed s3' and 'weed iam' commands, enabling high availability through automatic failover.
Key changes:
- Updated S3ApiServerOption.Filer to Filers ([]pb.ServerAddress)
- Updated IamServerOption.Filer to Filers ([]pb.ServerAddress)
- Modified -filer flag to accept comma-separated addresses
- Added getFilerAddress() helper methods for backward compatibility
- Updated all filer client calls to support multiple addresses
- Uses pb.WithOneOfGrpcFilerClients for automatic failover
Usage:
weed s3 -filer=localhost:8888,localhost:8889
weed iam -filer=localhost:8888,localhost:8889
The underlying FilerClient already supported multiple filers with health
tracking and automatic failover - this change exposes that capability
through the command-line interface.
* Add filer discovery: treat initial filers as seeds and discover peers from master
Enhances FilerClient to automatically discover additional filers in the same
filer group by querying the master server. This allows users to specify just
a few seed filers, and the client will discover all other filers in the cluster.
Key changes to wdclient/FilerClient:
- Added MasterClient, FilerGroup, and DiscoveryInterval fields
- Added thread-safe filer list management with RWMutex
- Implemented discoverFilers() background goroutine
- Uses cluster.ListExistingPeerUpdates() to query master for filers
- Automatically adds newly discovered filers to the list
- Added Close() method to clean up discovery goroutine
New FilerClientOption fields:
- MasterClient: enables filer discovery from master
- FilerGroup: specifies which filer group to discover
- DiscoveryInterval: how often to refresh (default 5 minutes)
Usage example:
masterClient := wdclient.NewMasterClient(...)
filerClient := wdclient.NewFilerClient(
[]pb.ServerAddress{"localhost:8888"}, // seed filers
grpcDialOption,
dataCenter,
&wdclient.FilerClientOption{
MasterClient: masterClient,
FilerGroup: "my-group",
},
)
defer filerClient.Close()
The initial filers act as seeds - the client discovers and adds all other
filers in the same group from the master. Discovered filers are added
dynamically without removing existing ones (relying on health checks for
unavailable filers).
* Address PR review comments: implement full failover for IAM operations
Critical fixes based on code review feedback:
1. **IAM API Failover (Critical)**:
- Replace pb.WithGrpcFilerClient with pb.WithOneOfGrpcFilerClients in:
* GetS3ApiConfigurationFromFiler()
* PutS3ApiConfigurationToFiler()
* GetPolicies()
* PutPolicies()
- Now all IAM operations support automatic failover across multiple filers
2. **Validation Improvements**:
- Add validation in NewIamApiServerWithStore() to require at least one filer
- Add validation in NewS3ApiServerWithStore() to require at least one filer
- Add warning log when no filers configured for credential store
3. **Error Logging**:
- Circuit breaker now logs when config load fails instead of silently ignoring
- Helps operators understand why circuit breaker limits aren't applied
4. **Code Quality**:
- Use ToGrpcAddress() for filer address in credential store setup
- More consistent with rest of codebase and future-proof
These changes ensure IAM operations have the same high availability guarantees
as S3 operations, completing the multi-filer failover implementation.
* Fix IAM manager initialization: remove code duplication, add TODO for HA

- Remove duplicate code for getting first filer address
- Extract filerAddr variable once and reuse
- Add TODO comment documenting the HA limitation for IAM manager
- Document that loadIAMManagerFromConfig and NewS3IAMIntegration need
updates to support multiple filers for full HA
Note: This is a known limitation when using filer-backed IAM stores.
The interfaces need to be updated to accept multiple filer addresses.
For now, documenting this limitation clearly.
* Document credential store HA limitation with TODO
Addresses review comment on auth_credentials.go:149
Changes:
- Add TODO comment documenting that SetFilerClient interface needs update
for multi-filer support
- Add informative log message indicating HA limitation
- Document that this is a known limitation for filer-backed credential stores
The SetFilerClient interface currently only accepts a single filer address.
To properly support HA, the credential store interfaces need to be updated
to handle multiple filer addresses.
* Track current active filer in FilerClient for better HA
Add GetCurrentFiler() method to FilerClient that returns the currently
active filer based on the filerIndex which is updated on successful
operations. This provides better availability than always using the
first filer.
Changes:
- Add FilerClient.GetCurrentFiler() method that returns current active filer
- Update S3ApiServer.getFilerAddress() to use FilerClient's current filer
- Add fallback to first filer if FilerClient not yet initialized
- Document IAM limitation (doesn't have FilerClient access)
Benefits:
- Single-filer operations (URLs, ReadFilerConf, etc.) now use the
currently active/healthy filer
- Better distribution and failover behavior
- FilerClient's round-robin and health tracking automatically
determines which filer to use
* Document ReadFilerConf HA limitation in lifecycle handlers
Addresses review comment on s3api_bucket_handlers.go:880
Add comment documenting that ReadFilerConf uses the current active filer
from FilerClient (which is better than always using first filer), but
doesn't have built-in multi-filer failover.
Add TODO to update filer.ReadFilerConf to support multiple filers for
complete HA. For now, it uses the currently active/healthy filer tracked
by FilerClient which provides reasonable availability.
* Document multipart upload URL HA limitation
Addresses review comment on s3api_object_handlers_multipart.go:442
Add comment documenting that part upload URLs point to the current
active filer (tracked by FilerClient), which is better than always
using the first filer but still creates a potential point of failure
if that filer becomes unavailable during upload.
Suggest TODO solutions:
- Use virtual hostname/load balancer for filers
- Have S3 server proxy uploads to healthy filers
Current behavior provides reasonable availability by using the
currently active/healthy filer rather than being pinned to first filer.
* Document multipart completion Location URL limitation
Addresses review comment on filer_multipart.go:187
Add comment documenting that the Location URL in CompleteMultipartUpload
response points to the current active filer (tracked by FilerClient).
Note that clients should ideally use the S3 API endpoint rather than
this direct URL. If direct access is attempted and the specific filer
is unavailable, the request will fail.
Current behavior uses the currently active/healthy filer rather than
being pinned to the first filer, providing better availability.
* Make credential store use current active filer for HA
Update FilerEtcStore to use a function that returns the current active
filer instead of a fixed address, enabling high availability.
Changes:
- Add SetFilerAddressFunc() method to FilerEtcStore
- Store uses filerAddressFunc instead of fixed filerGrpcAddress
- withFilerClient() calls the function to get current active filer
- Keep SetFilerClient() for backward compatibility (marked deprecated)
- Update S3ApiServer to pass FilerClient.GetCurrentFiler to store
Benefits:
- Credential store now uses currently active/healthy filer
- Automatic failover when filer becomes unavailable
- True HA for credential operations
- Backward compatible with old SetFilerClient interface
This addresses the credential store limitation - no longer pinned to
first filer, uses FilerClient's tracked current active filer.
* Clarify multipart URL comments: filer address not used for uploads
Update comments to reflect that multipart upload URLs are not actually
used for upload traffic - uploads go directly to volume servers.
Key clarifications:
- genPartUploadUrl: Filer address is parsed out, only path is used
- CompleteMultipartUpload Location: Informational field per AWS S3 spec
- Actual uploads bypass filer proxy and go directly to volume servers
The filer address in these URLs is NOT a HA concern because:
1. Part uploads: URL is parsed for path, upload goes to volume servers
2. Location URL: Informational only, clients use S3 endpoint
This addresses the observation that S3 uploads don't go through filers,
only metadata operations do.
* Remove filer address from upload paths - pass path directly
Eliminate unnecessary filer address from upload URLs by passing file
paths directly instead of full URLs that get immediately parsed.
Changes:
- Rename genPartUploadUrl() → genPartUploadPath() (returns path only)
- Rename toFilerUrl() → toFilerPath() (returns path only)
- Update putToFiler() to accept filePath instead of uploadUrl
- Remove URL parsing code (no longer needed)
- Remove net/url import (no longer used)
- Keep old function names as deprecated wrappers for compatibility
Benefits:
- Cleaner code - no fake URL construction/parsing
- No dependency on filer address for internal operations
- More accurate naming (these are paths, not URLs)
- Eliminates confusion about HA concerns
This completely removes the filer address from upload operations - it was
never actually used for routing, only parsed for the path.
* Remove deprecated functions: use new path-based functions directly
Remove deprecated wrapper functions and update all callers to use the
new function names directly.
Removed:
- genPartUploadUrl() → all callers now use genPartUploadPath()
- toFilerUrl() → all callers now use toFilerPath()
- SetFilerClient() → removed along with fallback code
Updated:
- s3api_object_handlers_multipart.go: uploadUrl → filePath
- s3api_object_handlers_put.go: uploadUrl → filePath, versionUploadUrl → versionFilePath
- s3api_object_versioning.go: toFilerUrl → toFilerPath
- s3api_object_handlers_test.go: toFilerUrl → toFilerPath
- auth_credentials.go: removed SetFilerClient fallback
- filer_etc_store.go: removed deprecated SetFilerClient method
Benefits:
- Cleaner codebase with no deprecated functions
- All variable names accurately reflect that they're paths, not URLs
- Single interface for credential stores (SetFilerAddressFunc only)
All code now consistently uses the new path-based approach.
* Fix toFilerPath: remove URL escaping for raw file paths
The toFilerPath function should return raw file paths, not URL-escaped
paths. URL escaping was needed when the path was embedded in a URL
(old toFilerUrl), but now that we pass paths directly to putToFiler,
they should be unescaped.
This fixes S3 integration test failures:
- test_bucket_listv2_encoding_basic
- test_bucket_list_encoding_basic
- test_bucket_listv2_delimiter_whitespace
- test_bucket_list_delimiter_whitespace
The tests were failing because paths were double-encoded (escaped when
stored, then escaped again when listed), resulting in %252B instead of
%2B for '+' characters.
Root cause: When we removed URL parsing in putToFiler, we should have
also removed URL escaping in toFilerPath since paths are now used
directly without URL encoding/decoding.
* Add thread safety to FilerEtcStore and clarify credential store comments
Address review suggestions for better thread safety and code clarity:
1. **Thread Safety**: Add RWMutex to FilerEtcStore
- Protects filerAddressFunc and grpcDialOption from concurrent access
- Initialize() uses write lock when setting function
- SetFilerAddressFunc() uses write lock
- withFilerClient() uses read lock to get function and dial option
- GetPolicies() uses read lock to check if configured
2. **Improved Error Messages**:
- Prefix errors with "filer_etc:" for easier debugging
- "filer address not configured" → "filer_etc: filer address function not configured"
- "filer address is empty" → "filer_etc: filer address is empty"
3. **Clarified Comments**:
- auth_credentials.go: Clarify that initial setup is temporary
- Document that it's updated in s3api_server.go after FilerClient creation
- Remove ambiguity about when FilerClient.GetCurrentFiler is used
Benefits:
- Safe for concurrent credential operations
- Clear error messages for debugging
- Explicit documentation of initialization order
* Enable filer discovery: pass master addresses to FilerClient
Fix two critical issues:
1. **Filer Discovery Not Working**: Master client was not being passed to
FilerClient, so peer discovery couldn't work
2. **Credential Store Design**: Already uses FilerClient via GetCurrentFiler
function - this is the correct design for HA
Changes:
**Command (s3.go):**
- Read master addresses from GetFilerConfiguration response
- Pass masterAddresses to S3ApiServerOption
- Log master addresses for visibility
**S3ApiServerOption:**
- Add Masters []pb.ServerAddress field for discovery
**S3ApiServer:**
- Create MasterClient from Masters when available
- Pass MasterClient + FilerGroup to FilerClient via options
- Enable discovery with 5-minute refresh interval
- Log whether discovery is enabled or disabled
**Credential Store:**
- Already correctly uses filerClient.GetCurrentFiler via function
- This provides HA without tight coupling to FilerClient struct
- Function-based design is clean and thread-safe
Discovery Flow:
1. S3 command reads filer config → gets masters + filer group
2. S3ApiServer creates MasterClient from masters
3. FilerClient uses MasterClient to query for peer filers
4. Background goroutine refreshes peer list every 5 minutes
5. Credential store uses GetCurrentFiler to get active filer
Now filer discovery actually works! ��
* Use S3 endpoint in multipart Location instead of filer address
* Add multi-filer failover to ReadFilerConf
* Address CodeRabbit review: fix buffer reuse and improve lock safety
Address two code review suggestions:
1. **Fix buffer reuse in ReadFilerConfFromFilers**:
- Use local []byte data instead of shared buffer
- Prevents partial data from failed attempts affecting successful reads
- Creates fresh buffer inside callback for masterClient path
- More robust to future changes in read helpers
2. **Improve lock safety in FilerClient**:
- Add *WithHealth variants that accept health pointer
- Get health pointer while holding lock, then release before calling
- Eliminates potential for lock confusion (though no actual deadlock existed)
- Clearer separation: lock for data access, atomics for health ops
Changes:
- ReadFilerConfFromFilers: var data []byte, create buf inside callback
- shouldSkipUnhealthyFilerWithHealth(health *filerHealth)
- recordFilerSuccessWithHealth(health *filerHealth)
- recordFilerFailureWithHealth(health *filerHealth)
- Keep old functions for backward compatibility (marked deprecated)
- Update LookupVolumeIds to use WithHealth variants
Benefits:
- More robust multi-filer configuration reading
- Clearer lock vs atomic operation boundaries
- No lock held during health checks (even though atomics don't block)
- Better code organization and maintainability
* add constant
* Fix IAM manager and post policy to use current active filer
* Fix critical race condition and goroutine leak
* Update weed/s3api/filer_multipart.go
Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>
* Fix compilation error and address code review suggestions
Address remaining unresolved comments:
1. **Fix compilation error**: Add missing net/url import
- filer_multipart.go used url.PathEscape without import
- Added "net/url" to imports
2. **Fix Location URL formatting** (all 4 occurrences):
- Add missing slash between bucket and key
- Use url.PathEscape for bucket names
- Use urlPathEscape for object keys
- Handles special characters in bucket/key names
- Before: http://host/bucketkey
- After: http://host/bucket/key (properly escaped)
3. **Optimize discovery loop** (O(N*M) → O(N+M)):
- Use map for existing filers (O(1) lookup)
- Reduces time holding write lock
- Better performance with many filers
- Before: Nested loop for each discovered filer
- After: Build map once, then O(1) lookups
Changes:
- filer_multipart.go: Import net/url, fix all Location URLs
- filer_client.go: Use map for efficient filer discovery
Benefits:
- Compiles successfully
- Proper URL encoding (handles spaces, special chars)
- Faster discovery with less lock contention
- Production-ready URL formatting
* Fix race conditions and make Close() idempotent
Address CodeRabbit review #3512078995:
1. **Critical: Fix unsynchronized read in error message**
- Line 584 read len(fc.filerAddresses) without lock
- Race with refreshFilerList appending to slice
- Fixed: Take RLock to read length safely
- Prevents race detector warnings
2. **Important: Make Close() idempotent**
- Closing already-closed channel panics
- Can happen with layered cleanup in shutdown paths
- Fixed: Use sync.Once to ensure single close
- Safe to call Close() multiple times now
3. **Nitpick: Add warning for empty filer address**
- getFilerAddress() can return empty string
- Helps diagnose unexpected state
- Added: Warning log when no filers available
4. **Nitpick: Guard deprecated index-based helpers**
- shouldSkipUnhealthyFiler, recordFilerSuccess/Failure
- Accessed filerHealth without lock (races with discovery)
- Fixed: Take RLock and check bounds before array access
- Prevents index out of bounds and races
Changes:
- filer_client.go:
- Add closeDiscoveryOnce sync.Once field
- Use Do() in Close() for idempotent channel close
- Add RLock guards to deprecated index-based helpers
- Add bounds checking to prevent panics
- Synchronized read of filerAddresses length in error
- s3api_server.go:
- Add warning log when getFilerAddress returns empty
Benefits:
- No race conditions (passes race detector)
- No panic on double-close
- Better error diagnostics
- Safe with discovery enabled
- Production-hardened shutdown logic
* Fix hardcoded http scheme and add panic recovery
Address CodeRabbit review #3512114811:
1. **Major: Fix hardcoded http:// scheme in Location URLs**
- Location URLs always used http:// regardless of client connection
- HTTPS clients got http:// URLs (incorrect)
- Fixed: Detect scheme from request
- Check X-Forwarded-Proto header (for proxies) first
- Check r.TLS != nil for direct HTTPS
- Fallback to http for plain connections
- Applied to all 4 CompleteMultipartUploadResult locations
2. **Major: Add panic recovery to discovery goroutine**
- Long-running background goroutine could crash entire process
- Panic in refreshFilerList would terminate program
- Fixed: Add defer recover() with error logging
- Goroutine failures now logged, not fatal
3. **Note: Close() idempotency already implemented**
- Review flagged as duplicate issue
- Already fixed in commit 3d7a65c7e
- sync.Once (closeDiscoveryOnce) prevents double-close panic
- Safe to call Close() multiple times
Changes:
- filer_multipart.go:
- Add getRequestScheme() helper function
- Update all 4 Location URLs to use dynamic scheme
- Format: scheme://host/bucket/key (was: http://...)
- filer_client.go:
- Add panic recovery to discoverFilers()
- Log panics instead of crashing
Benefits:
- Correct scheme (https/http) in Location URLs
- Works behind proxies (X-Forwarded-Proto)
- No process crashes from discovery failures
- Production-hardened background goroutine
- Proper AWS S3 API compliance
* Fix S3 WithFilerClient to use filer failover
Critical fix for multi-filer deployments:
**Problem:**
- S3ApiServer.WithFilerClient() was creating direct connections to ONE filer
- Used pb.WithGrpcClient() with single filer address
- No failover - if that filer failed, ALL operations failed
- Caused test failures: "bucket directory not found"
- IAM Integration Tests failing with 500 Internal Error
**Root Cause:**
- WithFilerClient bypassed filerClient connection management
- Always connected to getFilerAddress() (current filer only)
- Didn't retry other filers on failure
- All getEntry(), updateEntry(), etc. operations failed if current filer down
**Solution:**
1. Added FilerClient.GetAllFilers() method
- Returns snapshot of all filer addresses
- Thread-safe copy to avoid races
2. Implemented withFilerClientFailover()
- Try current filer first (fast path)
- On failure, try all other filers
- Log successful failover
- Return error only if ALL filers fail
3. Updated WithFilerClient()
- Use filerClient for failover when available
- Fallback to direct connection for testing/init
**Impact:**
✅ All S3 operations now support multi-filer failover
✅ Bucket metadata reads work with any available filer
✅ Entry operations (getEntry, updateEntry) failover automatically
✅ IAM tests should pass now
✅ Production-ready HA support
**Files Changed:**
- wdclient/filer_client.go: Add GetAllFilers() method
- s3api/s3api_handlers.go: Implement failover logic
This fixes the test failure where bucket operations failed when
the primary filer was temporarily unavailable during cleanup.
* Update current filer after successful failover
Address code review: https://github.com/seaweedfs/seaweedfs/pull/7550#pullrequestreview-3512223723
**Issue:**
After successful failover, the current filer index was not updated.
This meant every subsequent request would still try the (potentially
unhealthy) original filer first, then failover again.
**Solution:**
1. Added FilerClient.SetCurrentFiler(addr) method:
- Finds the index of specified filer address
- Atomically updates filerIndex to point to it
- Thread-safe with RLock
2. Call SetCurrentFiler after successful failover:
- Update happens immediately after successful connection
- Future requests start with the known-healthy filer
- Reduces unnecessary failover attempts
**Benefits:**
✅ Subsequent requests use healthy filer directly
✅ No repeated failover to same unhealthy filer
✅ Better performance - fast path hits healthy filer
✅ Comment now matches actual behavior
* Integrate health tracking with S3 failover
Address code review suggestion to leverage existing health tracking
instead of simple iteration through all filers.
**Changes:**
1. Added address-based health tracking API to FilerClient:
- ShouldSkipUnhealthyFiler(addr) - check circuit breaker
- RecordFilerSuccess(addr) - reset failure count
- RecordFilerFailure(addr) - increment failure count
These methods find the filer by address and delegate to
existing *WithHealth methods for actual health management.
2. Updated withFilerClientFailover to use health tracking:
- Record success/failure for every filer attempt
- Skip unhealthy filers during failover (circuit breaker)
- Only try filers that haven't exceeded failure threshold
- Automatic re-check after reset timeout
**Benefits:**
✅ Circuit breaker prevents wasting time on known-bad filers
✅ Health tracking shared across all operations
✅ Automatic recovery when unhealthy filers come back
✅ Reduced latency - skip filers in failure state
✅ Better visibility with health metrics
**Behavior:**
- Try current filer first (fast path)
- If fails, record failure and try other HEALTHY filers
- Skip filers with failureCount >= threshold (default 3)
- Re-check unhealthy filers after resetTimeout (default 30s)
- Record all successes/failures for health tracking
* Update weed/wdclient/filer_client.go

* Enable filer discovery with empty filerGroup
Empty filerGroup is a valid value representing the default group.
The master client can discover filers even when filerGroup is empty.
**Change:**
- Remove the filerGroup != "" check in NewFilerClient
- Keep only masterClient != nil check
- Empty string will be passed to ListClusterNodes API as-is
This enables filer discovery to work with the default group.
