From 58a6f4f92d055e4822546d7d2ed9d094631ad804 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Tue, 3 Sep 2013 18:08:37 -0700 Subject: [PATCH] Bluetooth: Disable upper layer connections when user channel is active When the device has the user channel flag set, it means it is driven by an user application. In that case do not allow any connections from L2CAP or SCO sockets. This is the same situation as when the device has the raw flag set and it will then return EHOSTUNREACH.
