...so that we can read out the mount point between init
and start() in order to feed it to Client before it connects
to the MDS.
Signed-off-by: John Spray <john.spray@redhat.com>
Following sequence of events can happen.
- Client releases an inode, queues cap release message.
- A 'lookup' reply brings the same inode back, but the reply
doesn't contain xattrs because MDS didn't receive the cap release
message and thought client already has up-to-data xattrs.
The fix is force sending a getattr request to MDS if xattrs_version is 0.
The getattr mask is set to CEPH_STAT_CAP_XATTR, so MDS knows client does
not have xattr.

* Removing tiers from a base pool in use by CephFS is forbidden.
* Using CephFS pools as tiers is forbidden.

Fixes two things:
* EC pools are now permissible if they have a cache overlay
* Pools are not permissible if they are a cache tier.

The auth_cephx_key check always fails if there is a default
keyring in /etc/ceph/ available. Check if keyring exists and
fail with error message if keyring file in path.

set new inode's xattr version to 1 even if it has no xattr. This allow
client to differentiate no xattr in inode from MDS skips sending xattr
to client (because MDS think client already has uptodate xattr).

This is mostly relevant in testing clusters, but it ensures that an OSD
disconnecting from the monitor at the wrong time will still see any recent
map updates and prevent accidental loss of map injection into the OSD cluster.

Cancel the command op timeout event before we clear out the op from the
session struct. This isn't strictly necessary because command_op_cancel
will "gracefully" handle the case where the tid is no longer present, but
this avoids that noise and is cleaner.

The C_CancelOp path assumes op->session != NULL. Cancel that op before
we clear it. This fixes a crash like

We did this forever ago with mkcephfs, but ceph-disk didn't. Note that for
modern XFS this option is obsolete, but for older kernels it was not the
default.
