ceph: select FS_ENCRYPTION_ALGS if FS_ENCRYPTION

2024-01-25T23:45:13+00:00

commit 9c896d6bc3dfef86659a6a1fb25ccdea5dbef6a3 upstream.

The kconfig options for filesystems that support FS_ENCRYPTION are
supposed to select FS_ENCRYPTION_ALGS.  This is needed to ensure that
required crypto algorithms get enabled as loadable modules or builtin as
is appropriate for the set of enabled filesystems.  Do this for CEPH_FS
so that there aren't any missing algorithms if someone happens to have
CEPH_FS as their only enabled filesystem that supports encryption.

Merge tag 'ceph-for-6.7-rc1' of https://github.com/ceph/ceph-client

2023-11-10T17:52:56+00:00

Pull ceph updates from Ilya Dryomov:

 - support for idmapped mounts in CephFS (Christian Brauner, Alexander
   Mikhalitsyn).

   The series was originally developed by Christian and later picked up
   and brought over the finish line by Alexander, who also contributed
   an enabler on the MDS side (separate owner_{u,g}id fields on the
   wire).

   The required exports for mnt_idmap_{get,put}() in VFS have been acked
   by Christian and received no objection from Christoph.

 - a churny change in CephFS logging to include cluster and client
   identifiers in log and debug messages (Xiubo Li).

   This would help in scenarios with dozens of CephFS mounts on the same
   node which are getting increasingly common, especially in the
   Kubernetes world.

ceph: allow idmapped mounts

2023-11-03T22:28:34+00:00

Now that we converted cephfs internally to account for idmapped mounts
allow the creation of idmapped mounts on by setting the FS_ALLOW_IDMAP
flag.
