Hi Patrick,

1. >Can you describe the entire design, not just what you are changing? I 
assume that you will have to add some kind of access control somewhere to 
restrict device access. The goal is to explain why these controls cannot be 
circumvented.
At current NTB bt daemon use system dbus bus to implement NTB daemon method 
call.

However, if so, NTB daemon only run once. It means that NTB daemon only run on 
userA or userB.( system dbus will limit it)
I will modify the interface method call of NTB daemon to session dbus. It means 
that NTB daemon only run on userA and userB.
I don't modify any logic of NTB, just a little modification (modify system dbus 
interfaces to session dbus interfaces).

Best Regards
Zheng Wu

Can you describe the entire design, not just what you are changing? I assume 
that you will have to add some kind of access control somewhere to restrict 
device access. The goal is to explain why these controls cannot be circumvented.
