such as metadata and extended attributes are reported for the upper
directory only. These attributes of the lower directory are hidden.
credentials
-----------
By default, all access to the upper, lower and work directories is the
recorded mounter's MAC and DAC credentials. The incoming accesses are
checked against the caller's credentials.
In the case where caller MAC or DAC credentials do not overlap, a
use case available in older versions of the driver, the
override_creds mount flag can be turned off and help when the use
pattern has caller with legitimate credentials where the mounter
does not. Several unintended side effects will occur though. The
caller without certain key capabilities or lower privilege will not
always be able to delete files or directories, create nodes, or
search some restricted directories. The ability to search and read
a directory entry is spotty as a result of the cache mechanism not
retesting the credentials because of the assumption, a privileged
caller can fill cache, then a lower privilege can read the directory
cache. The uneven security model where cache, upperdir and workdir
are opened at privilege, but accessed without creating a form of
privilege escalation, should only be used with strict understanding
of the side effects and of the security policies.
