This is the fifth backport release in the Squid series. We recommend all users update to this release. ## Notable Changes MDS (Metadata Server) --------------------- - Fixed a segmentation fault relating to MDSContext completion and request queuing. OSD (Object Storage Daemon) --------------------------- - Rollback & Vector Fixes: Corrected rollback logic for partial write object information (OI) and optimized Erasure Coding (EC) by ensuring Twiddle creates a full-sized vector. RGW (RADOS Gateway) ------------------- - TLS 1.3 Ciphersuites: Introduced the ssl_ciphersuites configuration option for the Beast front-end to support TLS 1.3 cipher customizations. - S3 PutObject ACLs Fix: Fixed a bug where PutObject requests were erroneously rejected under BlockPublicAcls due to an incorrect comparison return value from canned_acl.compare(). - Multisite Sync Robustness: Resolved an infinite loop scenario in RGWBucketFullSyncCR when a source bucket was deleted mid-sync by introducing a mechanism to clear stateful data in reused bucket_list_result objects. - SNS Policy Evaluation: Updated ListTopics to use the account root ARN for policy evaluation when invoked by a non-root account user, preventing unexpected implicit denies from identity-based policies. - Presigned URLs: Fixed an internal server error occurring during the authentication process of presigned URLs. - Prerequest Hook: Restructured the order of execution so that the prerequest hook now runs after the authorization process has completed. - Object Tagging: Added handling for plain-text object tags during execution of RGWObjTags::decode(). - Beast Frontend Stability: Applied a strand executor to the Beast timeout timer to avoid concurrent socket access and potential race conditions. - Bucket Statistics: Added a fix for bucket stats execution when the underlying bucket index does not exist. We recommend users to update to this release.
