Add the logic to handle the following entities:

Domain:
  A domain is an unamed object containing a number of buses. A
  domain is automatically created when an instance of kdbusfs
  is mounted, and destroyed when it is unmounted.
  Every domain offers its own "control" device node to create
  buses.  Domains have no connection to each other and cannot
  see nor talk to each other.

Bus:
  A bus is a named object inside a domain. Clients exchange messages
  over a bus. Multiple buses themselves have no connection to each
  other; messages can only be exchanged on the same bus. The default
  entry point to a bus, where clients establish the connection to, is
  the "bus" device node /dev/kdbus/<bus name>/bus.  Common operating
  system setups create one "system bus" per system, and one "user
  bus" for every logged-in user. Applications or services may create
  their own private named buses.

might need a resync with the documentation.
