bt address memory copy error in btif_av_state_opening_handler()

[Problem]
In btif_av_state_opening_handler() BTIF_AV_CONNECT_REQ_EVT
handling, it reported the wrong bt address. It happened when remote speaker
connected back and local also tried to initiate the connection almost at the
same time, so that A2dpStateMachine recognized mTargetDevice and mIncomingDevice
as two different deivices. When it was final connected, A2dpStateMachine ignored
the connected event as "ERROR: current, target, or mIncomingDevice not null in
Disconnected".

[Solution]
Modify (bt_bdaddr_t*)p_data to ((btif_av_connect_req_t *)p_data)->target_bda in
btif_av_state_opening_handler() BTIF_AV_CONNECT_REQ_EVT handling. In previous
design, it would copy the address of target_bda and uuid in
btif_av_connect_req_t rather than the real address pointed by target_bda.

Fluoride Bluetooth stack

Building and running on AOSP

Just build AOSP - Fluoride is there by default.

Building and running on Linux

Instructions for Ubuntu, tested on 15.10 with GCC 5.2.1.

Install required libraries

sudo apt-get install libevent-dev

Install build tools

  • Install ninja build system
sudo apt-get install ninja-build

or download binary from https://github.com/ninja-build/ninja/releases

  • Install gn - meta-build system that generates NinjaBuild files.

Get sha1 of current version from here and then download corresponding executable:

wget -O gn http://storage.googleapis.com/chromium-gn/<gn.sha1>

i.e. if sha1 is "3491f6687bd9f19946035700eb84ce3eed18c5fa" (value from 24 Feb 2016) do

wget -O gn http://storage.googleapis.com/chromium-gn/3491f6687bd9f19946035700eb84ce3eed18c5fa

Then make binary executable and put it on your PATH, i.e.:

chmod a+x ./gn
sudo mv ./gn /usr/bin

Download source

mkdir ~/fluoride
cd ~/fluoride
git clone https://android.googlesource.com/platform/packages/modules/Bluetooth/system

Then fetch third party dependencies:

cd ~/fluoride/bt
mkdir third_party
cd third_party
git clone https://github.com/google/googletest.git
git clone https://android.googlesource.com/platform/external/libchrome
git clone https://android.googlesource.com/platform/external/modp_b64
git clone https://android.googlesource.com/platform/external/tinyxml2
git clone https://android.googlesource.com/platform/hardware/libhardware

And third party dependencies of third party dependencies:

cd fluoride/bt/third_party/libchrome/base/third_party
mkdir valgrind
cd valgrind
curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/valgrind.h?format=TEXT | base64 -d > valgrind.h
curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/memcheck.h?format=TEXT | base64 -d > memcheck.h

Generate your build files

cd ~/fluoride/bt
gn gen out/Default

Build

cd ~/fluoride/bt
ninja -C out/Default all

This will build all targets (the shared library, executables, tests, etc) and put them in out/Default. To build an individual target, replace "all" with the target of your choice, e.g. ninja -C out/Default net_test_osi.

Run

cd ~/fluoride/bt/out/Default
LD_LIBRARY_PATH=./ ./bluetoothtbd -create-ipc-socket=fluoride
