RHBA-2016:0688 - Bug Fix Advisory

Topic

Updated OpenStack Block Storage packages that resolve various issues are
now available for Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo)
for RHEL 7.

Description

Red Hat Enterprise Linux OpenStack Platform provides the facilities for
building a private or public infrastructure-as-a-service (IaaS) cloud
running on commonly available physical hardware. This advisory includes
packages for:

• OpenStack Block Storage service

OpenStack Block Storage (cinder) manages block storage mounting and the
presentation of such mounted block storage to instances. The back-end
physical storage can consist of local disks, Fiber Channel, iSCSI, and/or
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 through the Block Storage service's
API.

Changes to the openstack-cinder component:

• Previously, Cinder calculated filters, limits, and offset locally instead of in the database. This would result in large amounts of memory being required to perform these calculations because all non-deleted entries in the database would need to be retrieved. With this update, these calculations are now performed in the database, and only the data required for listing the output is retrieved. (BZ#1279547)
• Previously, Cinder did not take the "X-Forwarded-Host" header into account when generating pagination links, using the real server IP address instead of that of the load balancer. With this update, the "X-Forwarded-Host" header is used to build links if present. (BZ#1320098)

Solution
