[Bluez-devel] Multiple user/device model?

[Bluez-devel] Multiple user/device model?

[Fredrik Noring]

Hi,

Can multiple users have different sets of Bluetooth devices? I.e.
something like this:

    /home/peter/.bluetooth/devices/00:11:22:33:44:55/linkkeys
    /home/maria/.bluetooth/devices/99:88:77:66:55:44/linkkeys

With the following properties:

    1. User pairing and device management don't require
       administrative (root) privileges.
    2. Peter cannot remove/modify Maria's devices and vice versa.
    3. Would be excellent if Peter and Maria could use Bluetooth
       simultaneously, but good enough if only one at the time.

Any thoughts?

Thanks,
Fredrik

the idea is not bad, but it will never work this way. This is because
how the Bluetooth security architecture is designed. We need a central
root service that deals with the kernel side of HCI. However the control
of pairing etc. for users will be handled over D-Bus.

Regards

Marcel

Ah. Is there any documentation on how this D-BUS interface works?

Thanks,
Fredrik

Claudio has written something, but nothing is written in stone.

Hi Fredrik,

I sent a lot of emails about bluetoothd specification, but I didn't
receive enough feedbacks. bluetoothd will be the main entity
responsible to handle user requests(connections, device setup,
security, ...).

Currently, we are working on hcid D-Bus services. hcid is our
playground for validate some ideas. I developed a internal version
of the bluetoothd, but I need align with bluez community and
use the new communication interface (between kernel and the userspace)
that is being developed.

There is docs about bluetoothd available at:
http://www.cin.ufpe.br/~ckt/bluez

Your feedback is welcome!

Regards,
Claudio.
