Greetings, This is the second minor release in the Tentacle series. We recommend that all users update to this release. Notable Changes --------------- Rocky 10 package-based installs are now supported starting with v20.2.2. Please see the supported platforms ( https://docs.ceph.com/en/latest/start/os-recommendations/#platforms ) or current and planned support in Ceph. MDS (Metadata Server) --------------------- * Segmentation fault fixed due to incorrect queueing of request retries. OSD (Object Storage Daemon) --------------------------- * PGLog Missed List: Fixed a bug to ensure the correct version is attached to the missing list when ignoring log entries. * Data Integrity Asserts: Added assertions to explicitly catch potential corruption in the OSD missing list. RGW (RADOS Gateway) ------------------- * Lifecycle Management: Fixed lifecycle transition issues affecting encrypted multipart objects. * REST & Query Handling: RESTArgs::get_string() now properly URL-decodes incoming query parameters. RADOS / librados / neorados --------------------------- * Linger Operations: Rewrote safety checks to eliminate use-after-free vulnerabilities and LingerOp memory leaks when an unwatch operation returns ENOTCONN. Replaced the flawed is_valid_watch() check with a safe linger_by_cookie() lookup which safely manages LingerOp references using intrusive_ptr. Ensured librados linger callbacks hold a persistent reference to LingerOp to protect against races with simultaneous linger_cancel() requests. Configured librados::IoCtxImpl::aio_unwatch() to asynchronously deliver ENOTCONN to AioCompletion instead of returning the error directly. * Watch/Notify: Fixed neorados notification queue bounds enforcement so that an overflow marker is only appended on the first message exceeding capacity, rather than duplicating it on every subsequent message. Prevented double-cleanup triggers in watch/notify operations when incoming errors arrive after maybe_cleanup() runs. Fixed a bug where notify would lose original error values by ensuring it no longer attempts to decode empty responses. Enhanced io_context shutdown procedures to clear handlers and route cleanly through linger_cancel to avoid use-after-free states. * Async Utilities: Fixed an issue regarding the improper removal of objects from the async service list. Dashboard ----------------- * NVMeoF Revamp: Complete UI overhaul with DHCHAP controller key support, namespace encryption, and secure listeners configuration. * Pools & RGW: Added stretch cluster validation for pools, fixed RGW restart/stop issues, storage class restrictions, sync policy fixes, and MSR EC Profile support. * NFS: Toggle visibility for CephFS snapshots, fixed export creation and path value consistency issues ceph-volume ----------- * Inventory Scanning: Enhanced inventory discovery logic to automatically skip RAM disk devices (/dev/ram*). External Block Device (extblkdev) --------------------------------- * Plugin Stability: Fixed an assertion failure in the FCM plugin when encountering multivolume devices. Testing & QA (Suites / Tooling) ------------------------------- * OS Testing: Added CentOS 9 Stream as a supported host OS for the tentacle-p2p stress-split suite. * Dependency & Compilation: Configured bare-metal upgrade testing workloads (rbd-python) to inject python3-pytest via system packages to prevent test failures. Patched the blogbench workunit in qa/cephfs to gracefully handle "implicit declaration of function" warnings generated by newer GCC versions. Updated Lua scripts in qa/cephfs to respect missing kernels in the YAML configurations. * Boto3 Migration: Replaced outdated boto2 dependencies with boto3 across qa/radosgw_admin and qa/radosgw_admin_rest test frameworks, removing stale request log components and ACL test cases. * Tools: Resolved a crash occurring in tools/ceph-kvstore-tool during database closures, reduced BlueStore header exposure, and added missing compiler guards (WITH_BLUESTORE). We recommend users to update to this release.
