RHBA-2017:1755 - Bug Fix Advisory

Topic

An update is now available for Red Hat Ceph Storage 2.3.

Description

Red Hat Ceph Storage is a scalable, open, software-defined storage platform
that combines the most stable version of the Ceph storage system with a
Ceph management platform, deployment utilities, and support services.

Bug Fixes:

• Due to an incorrect time comparison in the rgw_dir_suggest_changes() function, under certain circumstances, deleted objects were incorrectly interpreted as incomplete delete transactions. As a consequence, the delete operations were reported successful in the Ceph Object Gateway logs, but the deleted objects were not correctly removed from bucket indexes. The incorrect time comparison has been fixed, and deleting objects work correctly. (BZ#1464099)
• In the Ceph Object Gateway multi-site configuration, when the data log for replication was larger than 1000 entries, queries to list the data log entered to an infinite loop and used all memory. As a consequence, objects were not replicated from the primary to the secondary Ceph Object Gateway. With this update, the queries no longer loop over the entries, which prevents them to enter to infinite loops. As a result, the objects are replicated as expected. (BZ#1465446)

Enhancement:

• The Ceph Object Gateway now supports a mechanism to associate opaque data to the object entries in internal bucket index metadata, and to recover this uninterpreted data in a custom HTTP header in bucket listing operations. This new feature enables users to store any user-defined data in the bucket index. Currently, interfaces to set and return user data are only available using the Swift access protocol. (BZ#1445891)
