v12.2.11 Luminous released

This is the eleventh bug fix release of the Luminous v12.2.x long term stable
release series. We recommend that all users upgrade to this release. Please note
the following precautions while upgrading.

Notable Changes

  • This release fixes the pg log hard limit bug from v12.2.9 (https://tracker.ceph.com/issues/36686).
    A flag called pglog_hardlimit has been introduced, which is off by default.
    This flag enables the feature that limits the length of the pg log. Users
    should run ceph osd set pglog_hardlimit after completely upgrading to
    12.2.11. Once the cluster has this flag set, the length of the pg log will
    be capped by a hard limit. Once set, the flag must not be unset anymore.
  • There have been fixes to RGW dynamic and manual resharding, which no longer
    leaves behind stale bucket instances to be removed manually. For finding and
    cleaning up older instances from a reshard a radosgw-admin command reshard
    stale-instances list
    and reshard stale-instances rm should do the necessary
    cleanup.
  • CVE-2018-14662: mon: limit caps allowed to access the config store
  • CVE-2018-16846: rgw: enforce bounds on max-keys/max-uploads/max-parts issue#35994
  • CVE-2018-16889: rgw: sanitize customer encryption keys from log output in v4 auth issue#37847
