Hi! A couple of changes since v1: - Dropped the dentry->d_flags change in ceph_mkdir(). Thanks to Xiubo suggestion, patch 0001 now skips calling ceph_fscrypt_prepare_context() if we're handling a snapshot. - Added error handling to ceph_get_snapdir() in patch 0001 (Jeff had already pointed that out but I forgot to include that change in previous revision). - Rebased patch 0002 to the latest wip-fscrypt branch. - Added some documentation regarding snapshots naming restrictions. As before, in order to test this code the following PRs are required: mds: add protection from clients without fscrypt support #45073 mds: use the whole string as the snapshot long name #45192 mds: support alternate names for snapshots #45224 mds: limit the snapshot names to 240 characters #45312 Luís Henriques (3): ceph: add support for encrypted snapshot names ceph: add support for handling encrypted snapshot names ceph: update documentation regarding snapshot naming limitations Documentation/filesystems/ceph.rst | 10 ++ fs/ceph/crypto.c | 158 +++++++++++++++++++++++++---- fs/ceph/crypto.h | 11 +- fs/ceph/inode.c | 31 +++++- 4 files changed, 182 insertions(+), 28 deletions(-)
