Bluetooth fixes for 2.6.20-rc5

Bluetooth fixes for 2.6.20-rc5

[Marcel Holtmann]

Hi Dave,

here are two additional fixes for the Bluetooth subsystem that should go
in before the final 2.6.20 release. It was possible that the well known
PSM could be bound by anybody. That should not be possible like TCP/IP
ports below 1024 are also restricted. The other one is a simple endian
fix. Please forward them to Linus as soon as possible.

Regards

Marcel

    [Bluetooth] Restrict well known PSM to privileged users
    
    The PSM values below 0x1001 of L2CAP are reserved for well known
    services. Restrict the possibility to bind them to privileged
    users.

    [Bluetooth] Missing endian swapping for L2CAP socket list
    
    The PSM value in the L2CAP socket list must be converted to host
    order before printing it.

Pulled, thanks Marcel.

BTW, do you know if anyone has successfully used the Linux
Bluetooth stack to communicate with the Nintendo Wii
controllers?  I am under the impression that they speak
bluetooth. :)

I have one of these and I played with it. They use HID over Bluetooth as
protocol, but all reports are vendor specific. So you need a specific
driver to make something useful out of these events.

However it is fun to switch on the leds and play with rumble pack or
motion sensor.

It really shouldn't be hard to reverse engineer this right?
Just press a button and see what it spits out?

Sure, the rotational events from the motion sensor et al. might take a
little time to figure out, but it should be doable.

Hehe :-)

some stuff has already been done in this area. I put some information
and a link to it on my page:

http://www.holtmann.org/linux/bluetooth/wiimote.html

The hardest part at the moment is to get the speaker on the Wiimote
doing something useful and I personally wanna get to the internal flash
area of the Bluetooth chip.
