f1f50e0218 fscrypt: fix metadata directory permissions
Call Mount.Setup with SingleUserWritable constant instead of 0o755,
which is silently ignored and causes the /.fscrypt/{policy,protector}/
directories to have mode 000.

97cb1b6672 fscrypt: Update mount info before create context
NewContextFrom{Mountpoint,Path} functions use cached
`/proc/self/mountinfo` to find mounted file systems by device ID.
Since we run fscrypt as a library in a long-lived process the cached
information is likely to be stale. Stale entries may map device IDs to
mount points of already destroyed RBDs and fail context creation.
Updating the cache beforehand prevents this.

b7703faf37 util: make inode metrics optional in FilesystemNodeGetVolumeStats()
CephFS does not have a concept of "free inodes", inodes get allocated
on-demand in the filesystem.

This confuses alerting managers that expect a (high) number of free
inodes, and warnings get produced if the number of free inodes is not
high enough. This causes alerts to always get reported for CephFS.

To prevent the false-positive alerts from happening, the
NodeGetVolumeStats procedure for CephFS (and CephNFS) will not contain
inodes in the reply anymore.

71e5b3f922 rbd: remove dummy image workaround
To address the problem that snapshot
schedules are triggered for volumes
that are promoted, a dummy image was
disabled/enabled for replication.
This was done as a workaround, because the
promote operation was not triggering
the schedules for the image being promoted.

The bugs related to the same have been fixed in
RBD mirroring functionality and hence the
workaround #2656 can be removed from the code base.

c2280011d1 rbd: Report remote peer readiness if Up and status.Unknown
Current code uses an !A && !B condition incorrectly to
test A:Up and B:status for a remote peer image.

This should be !A || !B as we require both conditions to
be in the specified state (Up: true, and status Unknown).

This is corrected by this commit, and further fixes:
- check and return ready only when a remote site is
found in the status output
- check if all peer sites are ready, if multiple are found
and return ready appropriately

8d7b6ee59f rbd: consider mirror deamon state for ResyncVolume
During ResyncVolume we check if the image
is in an error state, and we resync.
After resync, the image will move to
either the `Error` or the `Resyncing` state.
And if the image is in the above two
conditions, we will return a successful
response and Ready=false so that the
consumer can wait until the volume is
ready to use. If the image is in any
other state we return an error message
to indicate the syncing is not going on.
The whole resync and image state change
depends on the rbd mirror daemon. If the
mirror daemon is not running, the image
can be in Resyncing or Unknown state.
The Ramen marks the volume replication as
secondary, and once the resync starts, it
will delete the volume replication CR as a
cleanup process.

As we dont have a check for the rbd mirror
daemon, we are returning a resync success
response and Ready=false. Due to this false
response Ramen is assuming the resync started
and deleted the volume replication CR, and
because of this, the cluster goes into a bad
state and needs manual intervention.

bc9ad3d9f1 rbd: add dummy attacher implementation
previously, it was a requirement to have attacher sidecar for CSI
drivers and there had an implementation of dummy mode of operation.
However skipAttach implementation has been stabilized and the dummy
mode of operation is going to be removed from the external-attacher.
Considering this driver  work on volumeattachment objects for NBD driver
use cases, we have to implement dummy controllerpublish and unpublish
and thus keep supporting our operations even in absence of dummy mode
of operation in the sidecar.

This commit make a NOOP controller publish and unpublish for RBD driver.

CephFS driver does not require attacher and it has already been made free
from the attachment operations.
