Rootcanal HCI HAL: Set read from socket blocking

In HciSocketDevice::SendHci, rootcanal first writes to HCI socket one
byte HCI packet type first, then HCI packet body. When the stack
receives the first byte, it tries to read the entire packet, but
sometimes the rest of packet was not delivered yet, so the stack will
crash. Instead, the stack should be blocked until all bytes are read,
with a 3 second timeout when rootcanal can't deliver all bytes to stack.

Test: try cert/run_cert.sh multiple times

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 14.04 with Clang 3.5.0 and 16.10 with Clang 3.8.0

Download source

mkdir ~/fluoride
cd ~/fluoride
git clone https://android.googlesource.com/platform/system/bt

Install dependencies (require sudo access):

cd ~/fluoride/bt
build/install_deps.sh

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/aac
git clone https://android.googlesource.com/platform/external/libchrome
git clone https://android.googlesource.com/platform/external/libldac
git clone https://android.googlesource.com/platform/external/modp_b64
git clone https://android.googlesource.com/platform/external/tinyxml2

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

NOTE: If system/bt is checked out under AOSP, then create symbolic links instead of downloading sources

cd system/bt
mkdir third_party
cd third_party
ln -s ../../../external/aac aac
ln -s ../../../external/libchrome libchrome
ln -s ../../../external/libldac libldac
ln -s ../../../external/modp_b64 modp_b64
ln -s ../../../external/tinyxml2 tinyxml2
ln -s ../../../external/googletest googletest

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

Eclipse IDE Support

  1. Follows the Chromium project Eclipse Setup Instructions until "Optional: Building inside Eclipse" section (don't do that section, we will set it up differently)

  2. Generate Eclipse settings:

cd system/bt
gn gen --ide=eclipse out/Default

  1. In Eclipse, do File->Import->C/C++->C/C++ Project Settings, choose the XML location under system/bt/out/Default

  2. Right click on the project. Go to Preferences->C/C++ Build->Builder Settings. Uncheck "Use default build command", but instead using "ninja -C out/Default"

  3. Goto Behaviour tab, change clean command to "-t clean"
