Defined ErrVersionTokenMismatch and ErrCodeConflict for better optimistic concurrency support. * s3tables: update bucket handlers for multi-account support Ensured bucket ownership is correctly attributed to the authenticated account ID and updated ARNs to use the request-derived account ID. Added standard S3 existence checks for bucket deletion. * s3tables: update namespace handlers for multi-account support Updated namespace creation to use authenticated account ID for ownership and unified permission checks across all namespace operations to use the correct account principal. * s3tables: implement optimistic concurrency for table deletion Added VersionToken validation to handleDeleteTable. Refactored table listing to use request context for accurate ARN generation and fixed cross-namespace pagination issues. * s3tables: improve resource resolution and error mapping for policies and tagging Refactored resolveResourcePath to return resource type, enabling accurate NoSuchBucket vs NoSuchTable error codes. Added existence checks before deleting policies. * s3tables: enhance test robustness and resilience Updated random string generation to use crypto/rand in s3tables tests. Increased resilience of IAM distributed tests by adding "connection refused" to retryable errors. * s3tables: remove legacy principal fallback header Removed the fallback to X-Amz-Principal in getPrincipalFromRequest as S3 Tables is a new feature and does not require legacy header support. * s3tables: remove unused ExtractPrincipalFromContext function Removed the unused ExtractPrincipalFromContext utility and its accompanying iam/utils import to keep the new s3tables codebase clean. * s3tables: allow hyphens in namespace and table names Relaxed regex validation in utils.go to support hyphens in S3 Tables namespaces and table names, improving consistency with S3 bucket naming and allowing derived names from services like S3 Storage Lens. * s3tables: add isAuthError helper to handler.go * s3tables: refactor permission checks to use resource owner in bucket handlers * s3tables: refactor permission checks to use resource owner in namespace handlers * s3tables: refactor permission checks to use resource owner in table handlers * s3tables: refactor permission checks to use resource owner in policy and tagging handlers * ownerAccountID * s3tables: implement strict AWS-aligned name validation for buckets, namespaces, and tables * s3tables: enforce strict resource ownership and implement result filtering for buckets * s3tables: enforce strict resource ownership and implement result filtering for namespaces * s3tables: enforce strict resource ownership and implement result filtering for tables * s3tables: align getPrincipalFromRequest with account ID for IAM compatibility * s3tables: fix inconsistent permission check in handleCreateTableBucket * s3tables: improve pagination robustness and error handling in table listing handlers * s3tables: refactor handleDeleteTableBucket to use strongly typed AuthError * s3tables: align ARN regex patterns with S3 standards and refactor to constants * s3tables: standardize access denied errors using ErrAccessDenied constant * go fmt * s3tables: fix double-write issue in handleListTables Remove premature HTTP error writes from within WithFilerClient closure to prevent duplicate status code responses. Error handling is now consistently performed at the top level using isAuthError. * s3tables: update bucket name validation message Remove "underscores" from error message to accurately reflect that bucket names only allow lowercase letters, numbers, and hyphens. * s3tables: add table policy test coverage Add comprehensive test coverage for table policy operations: - Added PutTablePolicy, GetTablePolicy, DeleteTablePolicy methods to test client - Implemented testTablePolicy lifecycle test validating Put/Get/Delete operations - Verified error handling for missing policies * follow aws spec * s3tables: add request body size limiting Add request body size limiting (10MB) to readRequestBody method: - Define maxRequestBodySize constant to prevent unbounded reads - Use io.LimitReader to enforce size limit - Add explicit error handling for oversized requests - Prevents potential DoS attacks via large request bodies * S3 Tables API now properly enforces resource policies addressing the critical security gap where policies were created but never evaluated. * s3tables: Add upper bound validation for MaxTables parameter MaxTables is user-controlled and influences gRPC ListEntries limits via uint32(maxTables2). Without an upper bound, very large values can overflow uint32 or cause excessively large directory scans. Cap MaxTables to 1000 and return InvalidRequest for out-of-range values, consistent with S3 MaxKeys handling. s3tables: Add upper bound validation for MaxBuckets parameter MaxBuckets is user-controlled and used in uint32(maxBuckets2) for ListEntries. Very large values can overflow uint32 or trigger overly expensive scans. Cap MaxBuckets to 1000 and reject out-of-range values, consistent with MaxTables handling and S3 MaxKeys validation elsewhere in the codebase. s3tables: Validate bucket name in parseBucketNameFromARN() Enforce the same bucket name validation rules (length, characters, reserved prefixes/suffixes) when extracting from ARN. This prevents accepting ARNs that the system would never create and ensures consistency with CreateTableBucket validation. * s3tables: Fix parseTableFromARN() namespace and table name validation - Remove dead URL unescape for namespace (regex [a-z0-9_]+ cannot contain percent-escapes) - Add URL decoding and validation of extracted table name via validateTableName() to prevent callers from bypassing request validation done in other paths * s3tables: Rename tableMetadataInternal.Schema to Metadata The field name 'Schema' was confusing given it holds a TableMetadata struct and serializes as 'metadata' in JSON. Rename to 'Metadata' for clarity and consistency with the JSON tag and intended meaning. s3tables: Improve bucket name validation error message Replace misleading character-only error message with generic 'invalid bucket name'. The isValidBucketName() function checks multiple constraints beyond character set (length, reserved prefixes/suffixes, start/end rules), so a specific character message is inaccurate. * s3tables: Separate permission checks for tagging and untagging - Add CanTagResource() to check TagResource permission - Add CanUntagResource() to check UntagResource permission - Update CanManageTags() to check both operations (OR logic) This prevents UntagResource from incorrectly checking 'ManageTags' permission and ensures each operation validates the correct permission when per-operation permissions are enforced. * s3tables: Consolidate getPrincipalFromRequest and getAccountID into single method Both methods had identical implementations - they return the account ID from request header or fall back to handler's default. Remove the duplicate getPrincipalFromRequest and use getAccountID throughout, with updated comment explaining its dual role as both caller identity and principal for permission checks. * s3tables: Fetch bucket policy in handleListTagsForResource for permission evaluation Update handleListTagsForResource to fetch and pass bucket policy to CheckPermission, matching the behavior of handleTagResource/handleUntagResource. This enables bucket-policy-based permission grants to be evaluated for ListTagsForResource, not just ownership-based checks. * s3tables: Extract resource owner and bucket extraction into helper method Create extractResourceOwnerAndBucket() helper to consolidate the repeated pattern of unmarshaling metadata and extracting bucket name from resource path. This pattern was duplicated in handleTagResource, handleListTagsForResource, and handleUntagResource. Update all three handlers to use the helper. Also update remaining uses of getPrincipalFromRequest() (in handler_bucket_create, handler_bucket_get_list_delete, handler_namespace) to use getAccountID() after consolidating the two identical methods. * s3tables: Add log message when cluster shutdown times out The timeout path (2 second wait for graceful shutdown) was silent. Add a warning log message when it occurs to help diagnose flaky test issues and indicate when the mini cluster didn't shut down cleanly. * s3tables: Use policy_engine wildcard matcher for complete IAM compatibility Replace the custom suffix-only wildcard implementation in matchesActionPattern and matchesPrincipal with the policy_engine.MatchesWildcard function from PR #8052. This enables full wildcard support including: - Middle wildcards: s3tables:GetTable matches GetTable - Question mark wildcards: Get? matches any single character - Combined patterns: s3tables:Table* matches any action containing 'Table' Benefits: - Code reuse: eliminates duplicate wildcard logic - Complete IAM compatibility: supports all AWS wildcard patterns - Performance: uses efficient O(n) backtracking algorithm - Consistency: same wildcard behavior across S3 API and S3 Tables Add comprehensive unit tests covering exact matches, suffix wildcards, middle wildcards, question marks, and combined patterns for both action and principal matching. * go fmt * s3tables: Fix vet error - remove undefined c.t reference in Stop() The TestCluster.Stop() method doesn't have access to testing.T object. Remove the log statement and keep the timeout handling comment for clarity. The original intent (warning about shutdown timeout) is still captured in the code comment explaining potential issues. * clean up * s3tables: Add t field to TestCluster for logging Add testing.T field to TestCluster struct and initialize it in startMiniCluster. This allows Stop() to properly log warnings when cluster shutdown times out. Includes the t field in the test cluster initialization and restores the logging statement in Stop(). s3tables: Fix bucket policy error handling in permission checks Replace error-swallowing pattern where all errors from getExtendedAttribute were ignored for bucket policy reads. Now properly distinguish between: - ErrAttributeNotFound: Policy not found is expected; continue with empty policy - Other errors: Return internal server error and stop processing Applied fix to all bucket policy reads in: - handleDeleteTableBucketPolicy (line 220) - handleTagResource (line 313) - handleUntagResource (line 405) - handleListTagsForResource (line 488) - And additional occurrences in closures This prevents silent failures and ensures policy-related errors are surfaced to callers rather than being silently ignored. * s3tables: Pre-validate namespace to return 400 instead of 500 Move validateNamespace call outside of filerClient.WithFilerClient closure so that validation errors return HTTP 400 (InvalidRequest) instead of 500 (InternalError). Before: Validation error inside closure → treated as internal error → 500 After: Validation error before closure → handled as bad request → 400 This provides correct error semantics: namespace validation is an input validation issue, not a server error. * Update weed/s3api/s3tables/handler.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * s3tables: Normalize action names to include service prefix Add automatic normalization of operations to full IAM-style action names (e.g., 's3tables:CreateTableBucket') in CheckPermission(). This ensures policy statements using prefixed actions (s3tables:) correctly match operations evaluated by permission helpers. Also fixes incorrect r.Context() passed to GetIdentityNameFromContext which expects http.Request. Now passes r directly. * s3tables: Use policy framework for table creation authorization Replace strict ownership check in CreateTable with policy-based authorization. Now checks both namespace and bucket policies for CreateTable permission, allowing delegation via resource policies while still respecting owner bypass. Authorization logic: - Namespace policy grants CreateTable → allowed - Bucket policy grants CreateTable → allowed - Otherwise → denied (even if same owner) This enables cross-principal table creation via policies while maintaining security through explicit allow/deny semantics. * s3tables: Use policy framework for GetTable authorization Replace strict ownership check with policy-based authorization in GetTable. Now checks both table and bucket policies for GetTable permission, allowing authorized non-owners to read table metadata. Authorization logic: - Table policy grants GetTable → allowed - Bucket policy grants GetTable → allowed - Otherwise → 404 NotFound (no access disclosed) Maintains security through policy evaluation while enabling read delegation. * s3tables: Generate ARNs using resource owner account ID Change ARN generation to use resource OwnerAccountID instead of caller identity (h.getAccountID(r)). This ensures ARNs are stable and consistent regardless of which principal accesses the resource. Updated generateTableBucketARN and generateTableARN function signatures to accept ownerAccountID parameter. All call sites updated to pass the resource owner's account ID from metadata. This prevents ARN inconsistency issues when multiple principals have access to the same resource via policies. * s3tables: Fix remaining policy error handling in namespace and bucket handlers Replace silent error swallowing (err == nil) with proper error distinction for bucket policy reads. Now properly checks ErrAttributeNotFound and propagates other errors as internal server errors. Fixed 5 locations: - handleCreateNamespace (policy fetch) - handleDeleteNamespace (policy fetch) - handleListNamespaces (policy fetch) - handleGetNamespace (policy fetch) - handleGetTableBucket (policy fetch) This prevents masking of filer issues when policies cannot be read due to I/O errors or other transient failures. * ci: Pin GitHub Actions to commit SHAs for s3-tables-tests Update all action refs to use pinned commit SHAs instead of floating tags: - actions/checkout: @v6 → @8e8c483 (v4) - actions/setup-go: @v6 → @0c52d54 (v5) - actions/upload-artifact: @v6 → @65d8626 (v4) Pinned SHAs improve reproducibility and reduce supply chain risk by preventing accidental or malicious changes in action releases. Aligns with repository conventions used in other workflows (e.g., go.yml). * s3tables: Add resource ARN validation to policy evaluation Implement resource-specific policy validation to prevent over-broad permission grants. Add matchesResource and matchesResourcePattern functions to validate statement Resource fields against specific resource ARNs. Add new CheckPermissionWithResource function that includes resource ARN validation, while keeping CheckPermission unchanged for backward compatibility. This enables policies to grant access to specific resources only: - statements with Resource: "arn:aws:s3tables:...:bucket/specific-bucket/" will only match when accessing that specific bucket - statements without Resource field match all resources (implicit ) - resource patterns support wildcards (* for any sequence, ? for single char) For future use: Handlers can call CheckPermissionWithResource with the target resource ARN to enforce resource-level access control. * Revert "ci: Pin GitHub Actions to commit SHAs for s3-tables-tests" This reverts commit `01da26fbcb`. * s3tables: Remove duplicate bucket extraction logic in helper Move bucket name extraction outside the if/else block in extractResourceOwnerAndBucket since the logic is identical for both ResourceTypeTable and ResourceTypeBucket cases. This reduces code duplication and improves maintainability. The extraction pattern (parts[1] from /tables/{bucket}/...) works for both resource types, so it's now performed once before the type-specific metadata unmarshaling. * go fmt * s3tables: Fix ownership consistency across handlers Address three related ownership consistency issues: 1. CreateNamespace now sets OwnerAccountID to bucketMetadata.OwnerAccountID instead of request principal. This prevents namespaces created by delegated callers (via bucket policy) from becoming unmanageable, since ListNamespaces filters by bucket owner. 2. CreateTable now: - Fetches bucket metadata to use correct owner for bucket policy evaluation - Uses namespaceMetadata.OwnerAccountID for namespace policy checks - Uses bucketMetadata.OwnerAccountID for bucket policy checks - Sets table OwnerAccountID to namespaceMetadata.OwnerAccountID (inherited) 3. GetTable now: - Fetches bucket metadata to use correct owner for bucket policy evaluation - Uses metadata.OwnerAccountID for table policy checks - Uses bucketMetadata.OwnerAccountID for bucket policy checks This ensures: - Bucket owner retains implicit "owner always allowed" behavior even when evaluating bucket policies - Ownership hierarchy is consistent (namespace owned by bucket, table owned by namespace) - Cross-principal delegation via policies doesn't break ownership chains * s3tables: Fix ListTables authorization and policy parsing Make ListTables authorization consistent with GetTable/CreateTable: 1. ListTables authorization now evaluates policies instead of owner-only checks: - For namespace listing: checks namespace policy AND bucket policy - For bucket-wide listing: checks bucket policy - Uses CanListTables permission framework 2. Remove owner-only filter in listTablesWithClient that prevented policy-based sharing of tables. Authorization is now enforced at the handler level, so all tables in the namespace/bucket are returned to authorized callers (who have access either via ownership or policy). 3. Add flexible PolicyDocument.UnmarshalJSON to support both single-object and array forms of Statement field: - Handles: {"Statement": {...}} - Handles: {"Statement": [{...}, {...}]} - Improves AWS IAM compatibility This ensures cross-account table listing works when delegated via bucket/namespace policies, consistent with the authorization model for other operations. * go fmt * s3tables: Separate table name pattern constant for clarity Define a separate tableNamePatternStr constant for the table name component in the ARN regex, even though it currently has the same value as tableNamespacePatternStr. This improves code clarity and maintainability, making it easier to modify if the naming rules for tables and namespaces diverge in the future. * refactor --------- Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>	5 days ago

Updated getPrincipalFromRequest to prioritize X-Amz-Account-ID header and
added getAccountID helper. Defined ErrVersionTokenMismatch and ErrCodeConflict
for better optimistic concurrency support.

* s3tables: update bucket handlers for multi-account support

Ensured bucket ownership is correctly attributed to the authenticated
account ID and updated ARNs to use the request-derived account ID. Added
standard S3 existence checks for bucket deletion.

* s3tables: update namespace handlers for multi-account support

Updated namespace creation to use authenticated account ID for ownership
and unified permission checks across all namespace operations to use the
correct account principal.

* s3tables: implement optimistic concurrency for table deletion

Added VersionToken validation to handleDeleteTable. Refactored table
listing to use request context for accurate ARN generation and fixed
cross-namespace pagination issues.

Refactored resolveResourcePath to return resource type, enabling accurate
NoSuchBucket vs NoSuchTable error codes. Added existence checks before
deleting policies.

* s3tables: enhance test robustness and resilience

Updated random string generation to use crypto/rand in s3tables tests.
Increased resilience of IAM distributed tests by adding "connection refused"
to retryable errors.

* s3tables: remove legacy principal fallback header

Removed the fallback to X-Amz-Principal in getPrincipalFromRequest as
S3 Tables is a new feature and does not require legacy header support.

* s3tables: remove unused ExtractPrincipalFromContext function

Removed the unused ExtractPrincipalFromContext utility and its
accompanying iam/utils import to keep the new s3tables codebase clean.

* s3tables: allow hyphens in namespace and table names

* s3tables: fix inconsistent permission check in handleCreateTableBucket

* s3tables: improve pagination robustness and error handling in table listing handlers

* s3tables: refactor handleDeleteTableBucket to use strongly typed AuthError

* s3tables: align ARN regex patterns with S3 standards and refactor to constants

* s3tables: standardize access denied errors using ErrAccessDenied constant

* go fmt

* s3tables: fix double-write issue in handleListTables

* s3tables: update bucket name validation message

Remove "underscores" from error message to accurately reflect that
bucket names only allow lowercase letters, numbers, and hyphens.

* s3tables: add table policy test coverage

Add comprehensive test coverage for table policy operations:
- Added PutTablePolicy, GetTablePolicy, DeleteTablePolicy methods to test client
- Implemented testTablePolicy lifecycle test validating Put/Get/Delete operations
- Verified error handling for missing policies

* follow aws spec

* s3tables: add request body size limiting

Add request body size limiting (10MB) to readRequestBody method:
- Define maxRequestBodySize constant to prevent unbounded reads
- Use io.LimitReader to enforce size limit
- Add explicit error handling for oversized requests
- Prevents potential DoS attacks via large request bodies

* S3 Tables API now properly enforces resource policies

addressing the critical security gap where policies were created but never evaluated.

* s3tables: Add upper bound validation for MaxTables parameter

MaxTables is user-controlled and influences gRPC ListEntries limits via
uint32(maxTables*2). Without an upper bound, very large values can overflow
uint32 or cause excessively large directory scans. Cap MaxTables to 1000 and
return InvalidRequest for out-of-range values, consistent with S3 MaxKeys
handling.

* s3tables: Add upper bound validation for MaxBuckets parameter

MaxBuckets is user-controlled and used in uint32(maxBuckets*2) for ListEntries.
Very large values can overflow uint32 or trigger overly expensive scans. Cap
MaxBuckets to 1000 and reject out-of-range values, consistent with MaxTables
handling and S3 MaxKeys validation elsewhere in the codebase.

* s3tables: Validate bucket name in parseBucketNameFromARN()

Enforce the same bucket name validation rules (length, characters, reserved
prefixes/suffixes) when extracting from ARN. This prevents accepting ARNs
that the system would never create and ensures consistency with
CreateTableBucket validation.

* s3tables: Fix parseTableFromARN() namespace and table name validation

- Remove dead URL unescape for namespace (regex [a-z0-9_]+ cannot contain
  percent-escapes)
- Add URL decoding and validation of extracted table name via
  validateTableName() to prevent callers from bypassing request validation
  done in other paths

* s3tables: Rename tableMetadataInternal.Schema to Metadata

The field name 'Schema' was confusing given it holds a *TableMetadata struct
and serializes as 'metadata' in JSON. Rename to 'Metadata' for clarity and
consistency with the JSON tag and intended meaning.

* s3tables: Improve bucket name validation error message

Replace misleading character-only error message with generic 'invalid bucket
name'. The isValidBucketName() function checks multiple constraints beyond
character set (length, reserved prefixes/suffixes, start/end rules), so a
specific character message is inaccurate.

* s3tables: Separate permission checks for tagging and untagging

- Add CanTagResource() to check TagResource permission
- Add CanUntagResource() to check UntagResource permission
- Update CanManageTags() to check both operations (OR logic)

This prevents UntagResource from incorrectly checking 'ManageTags' permission
and ensures each operation validates the correct permission when per-operation
permissions are enforced.

* s3tables: Consolidate getPrincipalFromRequest and getAccountID into single method

Both methods had identical implementations - they return the account ID from
request header or fall back to handler's default. Remove the duplicate
getPrincipalFromRequest and use getAccountID throughout, with updated comment
explaining its dual role as both caller identity and principal for permission
checks.

* s3tables: Fetch bucket policy in handleListTagsForResource for permission evaluation

Update handleListTagsForResource to fetch and pass bucket policy to
CheckPermission, matching the behavior of handleTagResource/handleUntagResource.
This enables bucket-policy-based permission grants to be evaluated for
ListTagsForResource, not just ownership-based checks.

* s3tables: Extract resource owner and bucket extraction into helper method

Create extractResourceOwnerAndBucket() helper to consolidate the repeated pattern
of unmarshaling metadata and extracting bucket name from resource path. This
pattern was duplicated in handleTagResource, handleListTagsForResource, and
handleUntagResource. Update all three handlers to use the helper.

Also update remaining uses of getPrincipalFromRequest() (in handler_bucket_create,
handler_bucket_get_list_delete, handler_namespace) to use getAccountID() after
consolidating the two identical methods.

* s3tables: Add log message when cluster shutdown times out

The timeout path (2 second wait for graceful shutdown) was silent. Add a
warning log message when it occurs to help diagnose flaky test issues and
indicate when the mini cluster didn't shut down cleanly.

* s3tables: Use policy_engine wildcard matcher for complete IAM compatibility

Replace the custom suffix-only wildcard implementation in matchesActionPattern
and matchesPrincipal with the policy_engine.MatchesWildcard function from
PR #8052. This enables full wildcard support including:

- Middle wildcards: s3tables:Get*Table matches GetTable
- Question mark wildcards: Get? matches any single character
- Combined patterns: s3tables:*Table* matches any action containing 'Table'

Benefits:
- Code reuse: eliminates duplicate wildcard logic
- Complete IAM compatibility: supports all AWS wildcard patterns
- Performance: uses efficient O(n) backtracking algorithm
- Consistency: same wildcard behavior across S3 API and S3 Tables

Add comprehensive unit tests covering exact matches, suffix wildcards,
middle wildcards, question marks, and combined patterns for both action
and principal matching.

* go fmt

* s3tables: Fix vet error - remove undefined c.t reference in Stop()

The TestCluster.Stop() method doesn't have access to testing.T object.
Remove the log statement and keep the timeout handling comment for clarity.
The original intent (warning about shutdown timeout) is still captured in
the code comment explaining potential issues.

* clean up

* s3tables: Add t field to TestCluster for logging

Add *testing.T field to TestCluster struct and initialize it in
startMiniCluster. This allows Stop() to properly log warnings when
cluster shutdown times out. Includes the t field in the test cluster
initialization and restores the logging statement in Stop().

* s3tables: Fix bucket policy error handling in permission checks

Replace error-swallowing pattern where all errors from getExtendedAttribute
were ignored for bucket policy reads. Now properly distinguish between:

- ErrAttributeNotFound: Policy not found is expected; continue with empty policy
- Other errors: Return internal server error and stop processing

Applied fix to all bucket policy reads in:
- handleDeleteTableBucketPolicy (line 220)
- handleTagResource (line 313)
- handleUntagResource (line 405)
- handleListTagsForResource (line 488)
- And additional occurrences in closures

This prevents silent failures and ensures policy-related errors are surfaced
to callers rather than being silently ignored.

* s3tables: Pre-validate namespace to return 400 instead of 500

Move validateNamespace call outside of filerClient.WithFilerClient closure
so that validation errors return HTTP 400 (InvalidRequest) instead of 500
(InternalError).

Before: Validation error inside closure → treated as internal error → 500
After: Validation error before closure → handled as bad request → 400

This provides correct error semantics: namespace validation is an input
validation issue, not a server error.

* Update weed/s3api/s3tables/handler.go

* s3tables: Normalize action names to include service prefix

Add automatic normalization of operations to full IAM-style action names
(e.g., 's3tables:CreateTableBucket') in CheckPermission(). This ensures
policy statements using prefixed actions (s3tables:*) correctly match
operations evaluated by permission helpers.

Also fixes incorrect r.Context() passed to GetIdentityNameFromContext
which expects *http.Request. Now passes r directly.

* s3tables: Use policy framework for table creation authorization

Replace strict ownership check in CreateTable with policy-based authorization.
Now checks both namespace and bucket policies for CreateTable permission,
allowing delegation via resource policies while still respecting owner bypass.

Authorization logic:
- Namespace policy grants CreateTable → allowed
- Bucket policy grants CreateTable → allowed
- Otherwise → denied (even if same owner)

This enables cross-principal table creation via policies while maintaining
security through explicit allow/deny semantics.

* s3tables: Use policy framework for GetTable authorization

Replace strict ownership check with policy-based authorization in GetTable.
Now checks both table and bucket policies for GetTable permission, allowing
authorized non-owners to read table metadata.

Authorization logic:
- Table policy grants GetTable → allowed
- Bucket policy grants GetTable → allowed
- Otherwise → 404 NotFound (no access disclosed)

Maintains security through policy evaluation while enabling read delegation.

* s3tables: Generate ARNs using resource owner account ID

Change ARN generation to use resource OwnerAccountID instead of caller
identity (h.getAccountID(r)). This ensures ARNs are stable and consistent
regardless of which principal accesses the resource.

Updated generateTableBucketARN and generateTableARN function signatures
to accept ownerAccountID parameter. All call sites updated to pass the
resource owner's account ID from metadata.

This prevents ARN inconsistency issues when multiple principals have
access to the same resource via policies.

* s3tables: Fix remaining policy error handling in namespace and bucket handlers

Replace silent error swallowing (err == nil) with proper error distinction
for bucket policy reads. Now properly checks ErrAttributeNotFound and
propagates other errors as internal server errors.

Fixed 5 locations:
- handleCreateNamespace (policy fetch)
- handleDeleteNamespace (policy fetch)
- handleListNamespaces (policy fetch)
- handleGetNamespace (policy fetch)
- handleGetTableBucket (policy fetch)

This prevents masking of filer issues when policies cannot be read due
to I/O errors or other transient failures.

* ci: Pin GitHub Actions to commit SHAs for s3-tables-tests

Update all action refs to use pinned commit SHAs instead of floating tags:
- actions/checkout: @v6 → @8e8c483 (v4)
- actions/setup-go: @v6 → @0c52d54 (v5)
- actions/upload-artifact: @v6 → @65d8626 (v4)

Pinned SHAs improve reproducibility and reduce supply chain risk by
preventing accidental or malicious changes in action releases. Aligns
with repository conventions used in other workflows (e.g., go.yml).

* s3tables: Add resource ARN validation to policy evaluation

Implement resource-specific policy validation to prevent over-broad
permission grants. Add matchesResource and matchesResourcePattern functions
to validate statement Resource fields against specific resource ARNs.

Add new CheckPermissionWithResource function that includes resource ARN
validation, while keeping CheckPermission unchanged for backward compatibility.

This enables policies to grant access to specific resources only:
- statements with Resource: "arn:aws:s3tables:...:bucket/specific-bucket/*"
  will only match when accessing that specific bucket
- statements without Resource field match all resources (implicit *)
- resource patterns support wildcards (* for any sequence, ? for single char)

For future use: Handlers can call CheckPermissionWithResource with the
target resource ARN to enforce resource-level access control.

* Revert "ci: Pin GitHub Actions to commit SHAs for s3-tables-tests"

This reverts commit 01da26fbcb.

* s3tables: Remove duplicate bucket extraction logic in helper

Move bucket name extraction outside the if/else block in
extractResourceOwnerAndBucket since the logic is identical for both
ResourceTypeTable and ResourceTypeBucket cases. This reduces code
duplication and improves maintainability.

The extraction pattern (parts[1] from /tables/{bucket}/...) works for
both resource types, so it's now performed once before the type-specific
metadata unmarshaling.

* go fmt

* s3tables: Fix ownership consistency across handlers

Address three related ownership consistency issues:

1. CreateNamespace now sets OwnerAccountID to bucketMetadata.OwnerAccountID
   instead of request principal. This prevents namespaces created by
   delegated callers (via bucket policy) from becoming unmanageable, since
   ListNamespaces filters by bucket owner.

2. CreateTable now:
   - Fetches bucket metadata to use correct owner for bucket policy evaluation
   - Uses namespaceMetadata.OwnerAccountID for namespace policy checks
   - Uses bucketMetadata.OwnerAccountID for bucket policy checks
   - Sets table OwnerAccountID to namespaceMetadata.OwnerAccountID (inherited)

3. GetTable now:
   - Fetches bucket metadata to use correct owner for bucket policy evaluation
   - Uses metadata.OwnerAccountID for table policy checks
   - Uses bucketMetadata.OwnerAccountID for bucket policy checks

This ensures:
- Bucket owner retains implicit "owner always allowed" behavior even when
  evaluating bucket policies
- Ownership hierarchy is consistent (namespace owned by bucket, table owned by namespace)
- Cross-principal delegation via policies doesn't break ownership chains

* s3tables: Fix ListTables authorization and policy parsing

Make ListTables authorization consistent with GetTable/CreateTable:

1. ListTables authorization now evaluates policies instead of owner-only checks:
   - For namespace listing: checks namespace policy AND bucket policy
   - For bucket-wide listing: checks bucket policy
   - Uses CanListTables permission framework

2. Remove owner-only filter in listTablesWithClient that prevented policy-based
   sharing of tables. Authorization is now enforced at the handler level, so all
   tables in the namespace/bucket are returned to authorized callers (who have
   access either via ownership or policy).

3. Add flexible PolicyDocument.UnmarshalJSON to support both single-object and
   array forms of Statement field:
   - Handles: {"Statement": {...}}
   - Handles: {"Statement": [{...}, {...}]}
   - Improves AWS IAM compatibility

This ensures cross-account table listing works when delegated via bucket/namespace
policies, consistent with the authorization model for other operations.

* go fmt

* s3tables: Separate table name pattern constant for clarity

Define a separate tableNamePatternStr constant for the table name component in
the ARN regex, even though it currently has the same value as
tableNamespacePatternStr. This improves code clarity and maintainability, making
it easier to modify if the naming rules for tables and namespaces diverge in the
future.

* refactor
