Where do things stand wrt LSM hooks for kdbus? I don't see any security
hook calls in the kdbus tree except for the purpose of metadata
collection of process security labels. But nothing for enforcing MAC
over kdbus IPC. binder has a set of security hooks for that purpose, so
it would be a regression wrt MAC enforcement to switch from binder to
kdbus without equivalent checking there.
