RedHat: RHSA-2020-4391:01 Moderate: openstack-cinder security update
Summary
OpenStack Block Storage (cinder) manages block storage mounting and the
presentation of such mounted block storage to instances. The backend
physical storage can consist of local disks, or Fiber Channel, iSCSI, and
NFS mounts attached to Compute nodes. In addition, Block Storage supports
volume backups, and snapshots for temporary save and restore operations.
Programmatic management is available via Block Storage's API.
Security Fix(es):
* Improper handling of ScaleIO backend credentials (CVE-2020-10755)
For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.
Bug Fix(es):
* Before this update, FC live migration was failing. With this update, the
correct device information is now sent to os-brick for FC for the
corresponding host. Also, the device is now removed from the correct
masking view when the live migration process has failed on the Compute
node. (BZ#1841157)
* Before this update, the 3PAR driver did not look at the `_name_id` field
for a possible volume ID, which caused volumes to be unusable after a live
migration. With this update, the driver is now aware of the `_name_id`
field as an alternative location for the volume ID, and live migrated
volumes now work as expected. (BZ#1841866)
* Before this update, the internal temporary snapshot, created during async
migration when creating a volume from a snapshot, was not being deleted
from the VNX storage.
For example, if we create a new volume, V2, from snapshot S1, which we
created from volume V1, an internal temporary snapshot, S2, is created from
copying S1. V1 now has two snapshots, S1 and S2. Although we delete V1, V2
and S1 from OpenStack Block Storage (cinder), S2 is not deleted. This
causes both V1 and S2 to remain on the VNX storage.
With this update, the temporary snapshot, S2, is deleted, and V1 can be
successfully deleted. (BZ#1843196)
