[Bug 1847822] Re: CephFS authorize fails with unknown cap type

[Billy Olsen]

I've added the regression-update tag due to this being introduced in the
12.2.12 update via the SRU process.

I've also built a package in a PPA with the latest version for testing
purposes. You can find it at https://launchpad.net/~billy-
olsen/+archive/ubuntu/lp1847822 and can verify that commit 9c18bd4e from
the aforementioned PR fixes this.

Title:
  CephFS authorize fails with unknown cap type

Bug description:
  Attempting to provide access to a user within Ceph to a specific mount
  path fails with unknown cap type. This appears to be due to the
  monitor not knowing how to validate the caps that are provided with
  the mount path per upstream bug https://tracker.ceph.com/issues/39395
  and subsequent pull requests.

  This is fixed in Mimic (13.1.0+) and included in the current Luminous
  devel release (upcoming 12.2.13).

  
  Steps to recreate:

  1. Install ceph w/ ceph-fs.

  2. Mount ceph filesystem and create subdirectory for restricting access
  $ ceph-fuse -k /etc/ceph/ceph.client.foo.keyring --id foo -m 10.5.0.5:6789 /mnt/ceph-fs
  $ mkdir /mnt/ceph-fs/bar

  3. Authorize access for ceph user to rw a directory
  $ ceph fs authorize ceph-fs client.foo /bar rw

  Expected Results:

  The authorize command to succeed

  Actual Results:

  Error EINVAL: unknown cap type '/bar'
