Keystore selinux and permission modules accept CStr instead of Context.
The libselinux wrapper provides a Context struct, that conveniently
wraps and owns a context string as returned by libselinux. However,
libbinder_rs provides a non owned string with a lifetime bounded
by the currently ongoing transaction. So instead of accepting
a reference to an owning Context, the check_access function in the
libselinux wrapper as well as the higher level permission function in
the permission module accept &CStr now which Context can also deref
into.
