Bug Description
=== SRU Justification ===
There is an abi incompatibility with current compat-wireless lbm and what we have in 3.0. 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-
=== Original Description ===
The bluetooth module doesn't seem to be compatible with the kernel.
$ sudo modprobe bluetooth
FATAL: Error inserting bluetooth (/lib/modules/
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.
