From f03585689fdff4ae256edd45a35bc2dd83d3684a Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 18 May 2010 13:20:32 +0200 Subject: Bluetooth: Add blacklist support for incoming connections In some circumstances it could be desirable to reject incoming connections on the baseband level. This patch adds this feature through two new ioctl's: HCIBLOCKADDR and HCIUNBLOCKADDR. Both take a simple Bluetooth address as a parameter. BDADDR_ANY can be used with HCIUNBLOCKADDR to remove all devices from the blacklist.

The only flag available for now is HCI_UART_RAW_DEVICE which allows to initialize a UART device into RAW mode from userspace. This is particularly useful for experimenting with Bluetooth controllers that don't yet have proper support in BlueZ.
