** Description changed: === SRU Justification === - There is an abi incompatability with current compat-wireless lbm and what we have in 3.0. That means that we have no way to load the bluetooth modules.

That means that we have no way to load the bluetooth modules. This is a serious problem for anyone that has a newer wireless card but also wants to use bluetooth == Fix == Remove the security_sk_clone call. This is just a call to copy over security information when cloning a socket, but it's something that we have never had in linux-3.0. This call was not exported in the linux-3.0 code which is why we can't load the module with that call included == Test Case == - Install inux-backports-modules-3.0.0 for Oneiric and confirm that you can't load bluetooth module or drivers like btusb because of symbol resolution errors. Apply the patch and notice that you cand load bluetooth and drivers with no problems. + Install inux-backports-modules-3.0.0 for Oneiric and confirm that you can't load bluetooth module or drivers like btusb because of symbol resolution errors. Apply the patch and notice that you can load bluetooth and drivers with no problems. === Original Description === The bluetooth module doesn't seem to be compatible with the kernel. $ sudo modprobe bluetooth FATAL: Error inserting bluetooth (/lib/modules/3.0.0-15-generic/updates/cw-3.1/bluetooth.ko): Unknown symbol in module, or unknown parameter (see dmesg) flo@flomedio: ~ $ dmesg [ 460.266866] bluetooth: Unknown symbol security_sk_clone (err 0) The same occurs on version 3.0.0-14 of this backports package. It makes bluetooth unavailable if linux-backports-* is installed.
