Fix L2cap LE COC security record leaks - When we are client, we don't need to register security during L2cap registration. - When we are done, we clean up security record by PSM; Service ID might be invalid. - Once the btif topshim facade initial commit is done, we can repro this and verify the fix with test automation. Tag: #stability Bug: 193142224 Test: CtsVerifier LE COC Client for many times; later we will have an automated test for this Change-Id: I90fd23ce26c65ca3314e0754a2630d3f63c5d5d8
Just build AOSP - Fluoride is there by default.
Instructions for a Debian based distribution:
You'll want to download some pre-requisite packages as well. If you're currently configured for AOSP development, you should have most required packages. Otherwise, you can use the following apt-get list or use the bootstrap script (see below) to get a list of packages missing on your system:
sudo apt-get install repo git-core gnupg flex bison gperf build-essential \ zip curl zlib1g-dev gcc-multilib g++-multilib \ x11proto-core-dev libx11-dev libncurses5 \ libgl1-mesa-dev libxml2-utils xsltproc unzip liblz4-tool libssl-dev \ libc++-dev libevent-dev \ flatbuffers-compiler libflatbuffers1 openssl \ libflatbuffers-dev libtinyxml2-dev \ libglib2.0-dev libevent-dev libnss3-dev libdbus-1-dev \ libprotobuf-dev ninja-build generate-ninja protobuf-compiler \ libre2-9
You will also need a recent-ish version of Rust and Cargo. Please follow the instructions on Rustup to install a recent version.
mkdir ~/fluoride cd ~/fluoride git clone https://android.googlesource.com/platform/packages/modules/Bluetooth/system
bootstrap.py is a helper script provided to set up your build environment. It will set up your build staging directory and also make sure you have all required system packages to build (should work on Debian and Ubuntu). You will still need to build some unpackaged dependencies.
To use it:
./bootstrap.py --base-dir=path/to/staging/dir --bt-dir=path/to/bt/dir
The following third-party dependencies are necessary but currently unavailable via a package manager. You may have to build these from source and install them to your local environment.
We provide a script to produce debian packages for those components. Please see the instructions in build/dpkg/README.txt for more details.
cd build/dpkg mkdir -p outdir/{modp_b64,libchrome} # Build and install modp_b64 pushd modp_b64 ./gen-src-pkg.sh $(readlink -f ../outdir/modp_b64) popd sudo dpkg -i outdir/modp_b64/*.dpkg # Build and install libchrome pushd libchrome ./gen-src-pkg.sh $(readlink -f ../outdir/libchrome) popd sudo dpkg -i outdir/libchrome/*.dpkg
The googletest packages provided by Debian/Ubuntu (libgmock-dev and libgtest-dev) do not provide pkg-config files, so you can build your own googletest using the steps below:
git clone https://github.com/google/googletest.git -b release-1.10.0 cd googletest # Main directory of the cloned repository. mkdir build # Create a directory to hold the build output. cd build cmake .. # Generate native build scripts for GoogleTest. sudo make install -DCMAKE_INSTALL_PREFIX=/usr # Optional steps if pkgconfig isn't installed to desired location # Modify the source (/usr/lib/x86_64-linux-gnu) and target (/usr/lib) based on # your local installation. for f in $(ls /usr/lib/x86_64-linux-gnu/pkgconfig/{gtest,gmock}*); do \ ln -sf $f /usr/lib/pkgconfig/$(basename $f); done
Note: Handled by bootstrap script.
Run the following to install Rust dependencies:
cargo install cxxbridge-cmd
Note: Handled by bootstrap script.
For host build, we depend on a few other repositories:
Clone these all somewhere and create your staging environment.
export STAGING_DIR=path/to/your/staging/dir mkdir ${STAGING_DIR} mkdir -p ${STAGING_DIR}/external ln -s $(readlink -f ${PLATFORM2_DIR}/common-mk) ${STAGING_DIR}/common-mk ln -s $(readlink -f ${PLATFORM2_DIR}/.gn) ${STAGING_DIR}/.gn ln -s $(readlink -f ${RUST_CRATE_DIR}) ${STAGING_DIR}/external/rust ln -s $(readlink -f ${PROTO_LOG_DIR}) ${STAGING_DIR}/external/proto_logging
We provide a build script to automate building assuming you've staged your build environment already as above. At this point, make sure you have all the pre-requisites installed (i.e. bootstrap script and other dependencies above) or you will see failures. In addition, you may need to set a --libdir= if your libraries are not stored in /usr/lib64 by default.
./build.py --output ${OUTPUT_DIR} --platform-dir ${STAGING_DIR} --clang
This will build all targets to the output directory you've given. You can also build each stage separately (if you want to iterate on something specific):
You can choose to run only a specific stage by passing an arg via --target.
Currently, Rust builds are a separate stage that uses Cargo to build. See gd/rust/README.md for more information.
By default on Linux, we statically link libbluetooth so you can just run the binary directly. By default, it will try to run on hci0 but you can pass it --hci=N, where N corresponds to /sys/class/bluetooth/hciN.
$OUTPUT_DIR/debug/btadapterd --hci=$HCI INIT_gd_hci=true
