openstack/cinder — Week of 2026-11-14

NetApp ASAr2. The headline feature is snapshot and cache acceleration support for the NetApp ASAr2 driver, landing at roughly 1,700 lines in a single change (971174). It's by far the largest piece of the week.

Hardening, with backports. Three security-flavored fixes landed on master and were fanned out across stable branches. Invalid IQNs are now rejected on Cinder iSCSI targets (four branches), the SSH injection sanitizer utility was repaired (four branches), and attachments are now scoped by their own volume's project rather than the request context, with an accompanying fix for cross-project attachment access (four branches plus a follow-up). Together these account for over a dozen of the week's merges.

Driver fixes. copy_image_to_volume was fixed for the Quobyte driver, Dell PowerFlex got a volume detach fix, Everpure's network interface filter was corrected, and IBM SVC downgrades a noisy SSH error to a warning in _run_ssh. Test fixtures for Hitachi replication and Pure manageable snapshots were changed to operate on copies instead of mutating shared state.

Elsewhere. Volume usage notifications now carry cluster_name, the fields status constants were simplified across ~420 lines, and Everpure and Hitachi bumped driver versions for 2027.1 (Indri).
