bluetooth: Properly clone LSM attributes to newly created child connections
The Bluetooth stack has internal connection handlers for all of the various Bluetooth protocols, and unfortunately, they are currently lacking the LSM hooks found in the core network stack's connection handlers. I say unfortunately, because this can cause problems for users who have have an LSM enabled and are using certain Bluetooth devices. See one problem report below: * http://bugzilla.redhat.com/show_bug.cgi?id=741703 In order to keep things simple at this point in time, this patch fixes the problem by cloning the parent socket's LSM attributes to the newly created child socket. If we decide we need a more elaborate LSM marking mechanism for Bluetooth (I somewhat doubt this) we can always revisit this decision in the future. Reported-by: James M.
