From 2c428f6a0a745c753ecfe8904cd08be96c43f9fa Mon Sep 17 00:00:00 2001 From: Chris Lu Date: Fri, 2 Jan 2026 22:46:04 -0800 Subject: [PATCH] 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). ---
