qlowenergycontroller_bluez: too many open sockets and memory leak

Hey,

In my program bluetooth server I use only one static instance of "QLowEnergyController" class in "QLowEnergyController::PeripheralRole" during program lifetime.
I start to advertise waiting for client incoming connection .. after I serve him and he is disconnected I repeat advertising cycle. After few such cycles I noticed too many open sockets and no new connection could be established (Please look: qtconnectivity_5.9.7_to_many_open_files.log )

I compiled qtconnectivity 5.9.7 with patch (qtconnectivity_5.9.7_debug.patch) and was able to identify not released socket. In log qtconnectivity_5.9.7_debug.log :

qt.bluetooth.bluez: closeServerSocket : 3065 close socket: 12
qt.bluetooth.bluez: handleConnectionRequest : 3039 before setSocketDescriptor: 12
qt.bluetooth.bluez: handleConnectionRequest : 3053 after setSocketDescriptor: 13
qt.bluetooth.bluez: void QBluetoothSocketPrivate::_q_readNotify() 13 error: -1 "Connection reset by peer"
qt.bluetooth.bluez: closeServerSocket : 3065 close socket: 13
qt.bluetooth.bluez: handleConnectionRequest : 3039 before setSocketDescriptor: 13
qt.bluetooth.bluez: handleConnectionRequest : 3053 after setSocketDescriptor: 14
qt.bluetooth.bluez: void QBluetoothSocketPrivate::_q_readNotify() 14 error: -1 "Connection reset by peer"
qt.bluetooth.bluez: closeServerSocket : 3065 close socket: 14
qt.bluetooth.bluez: handleConnectionRequest : 3039 before setSocketDescriptor: 14
qt.bluetooth.bluez: handleConnectionRequest : 3053 after setSocketDescriptor: 15
qt.bluetooth.bluez: void QBluetoothSocketPrivate::_q_readNotify() 15 error: -1 "Connection reset by peer"

socket from line "handleConnectionRequest : 3039" is never closed

The same function "void QLowEnergyControllerPrivate::handleConnectionRequest"
is almost the same for version 5.13.

I believe there is also memory leak (no l2cpSocket deallocation).
I was manage to fix it with patch:
qtconnectivity_5.9.7_bluez_handleConnectionRequest.patch

Please evaluate it.
Thank you in advance,
Piotr
