There are no known issues about the above. As ConnMan is compiled either
as a 64bit or 32bit application, it's up to the Linux multiarch support
to get the surrounding pieces in place. As D-Bus is used as IPC, we can
be sure that the proper data types of proper length is relayed between
applications. The C compiler does it 64/32 bit job properly and as we
don't play any tricks with data types all is fine.
I think you are thinking of generic 64bit/32bit multiarch problems
above.
