Description

when last letter of keyring is modified, ceph-fuse can still mount the fs with this wrong keyring and write/read operation is allowed.

For example the original keyring is:
AQD6wjRZQPEcORAAeXPNPkN36VEiwc7Y/OBZcw==

the modified keyring is:
AQD6wjRZQPEcORAAeXPNPkN36VEiwc7Y/OBZcx==

or
AQD6wjRZQPEcORAAeXPNPkN36VEiwc7Y/OBZcy==

A change pattern seems like change the "w" to "x" or"A" to "B", it always work.
Numbers of keyrings are tested and the problem remains.
