作为第四个 Mimic v13.2.x 的长期支持版本,Ceph 13.2.4 Mimic 发布了。其中包含 13.2.3 的两项安全程序更新。建议所有用户升级。

Ceph 13.2.4 Mimic 更新内容如下

  • CVE-2018-16846: rgw: enforce bounds on max-keys/max-uploads/max-parts ( issue#35994 )

    • A new param rgw max listing results controls the upper bound  max-keys on Bucket listing operations (ListBucket, ListBucketVersions, ListBucketMultipartUploads( max-uploads ), ListMultipartUploadParts( max-parts )

  • CVE-2018-14662: mon: limit caps allowed to access the config store

Ceph 13.2.3 Mimic 更新内容如下

  • The default memory utilization for the mons has been increased

    somewhat. Rocksdb now uses 512 MB of RAM by default, which should

    be sufficient for small to medium-sized clusters; large clusters

    should tune this up. Also, the mon_osd_cache_size has been

    increase from 10 OSDMaps to 500, which will translate to an

    additional 500 MB to 1 GB of RAM for large clusters, and much less

    for small clusters.

  • Ceph v13.2.2 includes a wrong backport, which may cause mds to go into

    ‘damaged’ state when upgrading Ceph cluster from previous version.

    The bug is fixed in v13.2.3. If you are already running v13.2.2,

    upgrading to v13.2.3 does not require special action.

  • The bluestore_cache_* options are no longer needed. They are replaced

    by osd_memory_target, defaulting to 4GB. BlueStore will expand

    and contract its cache to attempt to stay within this

    limit. Users upgrading should note this is a higher default

    than the previous bluestore_cache_size of 1GB, so OSDs using

    BlueStore will use more memory by default.

    For more details, see the  BlueStore docs .

  • This version contains an upgrade bug, http://tracker.ceph.com/issues/36686 ,

    due to which upgrading during recovery/backfill can cause OSDs to fail. This

    bug can be worked around, either by restarting all the OSDs after the upgrade,

    or by upgrading when all PGs are in “active+clean” state. If you have already

    successfully upgraded to 13.2.2, this issue should not impact you. Going

    forward, we are working on a clean upgrade path for this feature.
