v13.2.9 Mimic released

This is the ninth and very likely the last stable release in the Ceph Mimic
stable release series. This release fixes bugs across all components and also
contains a RGW security fix. We recommend all mimic users to upgrade to this version.

Notable Changes

  • CVE-2020-1760: Fixed XSS due to RGW GetObject header-splitting
  • The configuration value osd_calc_pg_upmaps_max_stddev used for upmap
    balancing has been removed. Instead use the mgr balancer config
    upmap_max_deviation which now is an integer number of PGs of deviation
    from the target PGs per OSD. This can be set with a command like
    ceph config set mgr mgr/balancer/upmap_max_deviation 2. The default
    upmap_max_deviation is 1. There are situations where crush rules
    would not allow a pool to ever have completely balanced PGs. For example, if
    crush requires 1 replica on each of 3 racks, but there are fewer OSDs in 1 of
    the racks. In those cases, the configuration value can be increased.
  • The cephfs-data-scan scan_links command now automatically repair inotables
    and snaptable.
