20.1.0
^^^^^^


Upgrade Notes
*************

* This release introduces a new configuration option,
  "vmdk_allowed_types", that specifies the list of VMDK image
  subformats that Cinder will allow.  The default setting allows only
  the 'streamOptimized' and 'monolithicSparse' subformats, which do
  not use named extents.


Security Issues
***************

* This release introduces a new configuration option,
  "vmdk_allowed_types", that specifies the list of VMDK image
  subformats that Cinder will allow in order to prevent exposure of
  host information by modifying the named extents in a VMDK image. The
  default setting allows only the 'streamOptimized' and
  'monolithicSparse' subformats, which do not use named extents.

* As part of the fix for Bug #1996188
  (https://bugs.launchpad.net/cinder/+bug/1996188), cinder is now more
  strict in checking that the "disk_format" recorded for an image (as
  revealed by the Image Service API image-show response) matches what
  cinder detects when it downloads the image.  Thus, some requests to
  create a volume from a source image that had previously succeeded
  may fail with an "ImageUnacceptable" error.


Bug Fixes
*********

* RBD Driver bug #1957073
  (https://bugs.launchpad.net/cinder/+bug/1957073): Fixed snapshot
  deletion failure when its volume doesn't exist.

* IBM Spectrum Virtualize Family driver: Bug #1976499
  (https://bugs.launchpad.net/cinder/+bug/1976499): Setting correct
  SVC Code level for lsfcportsetmember call.

* Bug #1978729 (https://bugs.launchpad.net/cinder/+bug/1978729):
  Fixed context.message_action is None on errors by backup drivers.
  The message_* properties of the context were not passed during rpc,
  which caused a double exception when a backup driver raised an
  exception, masking the actual backup driver exception.

* Infinidat Driver bug #1981354
  (https://bugs.launchpad.net/cinder/+bug/1981354): Fixed Infinidat
  driver to return all configured and enabled iSCSI portals for a
  given network space.

* Bug #1996188 (https://bugs.launchpad.net/cinder/+bug/1996188):
  Fixed issue where a VMDK image file whose createType allowed named
  extents could expose host information.  This change introduces a new
  configuration option, "vmdk_allowed_types", that specifies the list
  of VMDK image subformats that Cinder will allow.  The default
  setting allows only the 'streamOptimized' and 'monolithicSparse'
  subformats.

* RBD driver bug #1916843
  (https://bugs.launchpad.net/cinder/+bug/1916843): Fixed rpc timeout
  when backing up RBD snapshot. We no longer flatten temporary volumes
  and snapshots.

* NFS driver bug #1946059
  (https://bugs.launchpad.net/cinder/+bug/1946059): Fixed revert to
  snapshot operation.

* Hitachi driver bug #1989176
  (https://bugs.launchpad.net/cinder/+bug/1989176): Fixed Hitachi
  driver to output a message for resource lock correctly.

* NetApp SolidFire driver Bug #1934435
  (https://bugs.launchpad.net/cinder/+bug/1934435): Fixed errors that
  might occur when an operation is made to a volume at the same time
  as the Element OS upgrades.

* PowerMax driver bug #1979668
  (https://bugs.launchpad.net/cinder/+bug/1979668): Fixed visibility
  of manageable volumes in multiple storage groups.

* PowerStore driver bug #1981068
  (https://bugs.launchpad.net/cinder/+bug/1981068): Fixed request data
  validation for the REST client.


Other Notes
***********

* Unified how cinder calculates the virtual free storage space for a
  pool. Previously Cinder had 2 different mechanisms for calculating
  the virtual free storage.  Now both the Capacity Filter and the
  Capacity Weigher use the same mechanism, which is based upon the
  defined terms in https://specs.openstack.org/openstack/cinder-
  specs/specs/queens/provisioning-improvements.html
