From baab793225c9badf46309f56982eb1012dbaac80 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 4 Sep 2016 05:13:46 +0200 Subject: [PATCH] Bluetooth: Fix wrong New Settings event when closing HCI User Channel When closing HCI User Channel, the New Settings event was send out to inform about changed settings. However such event is wrong since the exclusive HCI User Channel access is active until the Index Added event has been sent. @ USER Close: test @ MGMT Event: New Settings (0x0006) plen 4 Current settings: 0x00000ad0 Bondable Secure Simple Pairing BR/EDR Low Energy Secure Connections = Close Index: 00:14:EF:22:04:12 @ MGMT Event: Index Added (0x0004) plen 0 Calling __mgmt_power_off from hci_dev_do_close requires an extra check for an active HCI User Channel.
