* 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

* fix test_bucket_list_objects_anonymous and test_bucket_listv2_objects_anonymous
The tests test_bucket_list_objects_anonymous and test_bucket_listv2_objects_anonymous were failing because they try to set bucket ACL to public-read, but SeaweedFS only supported private ACL.
Updated PutBucketAclHandler to use the existing ExtractAcl function which already supports all standard S3 canned ACLs
Replaced the hardcoded check for only private ACL with proper ACL parsing that handles public-read, public-read-write, authenticated-read, bucket-owner-read, bucket-owner-full-control, etc.
Added unit tests to verify all standard canned ACLs are accepted
