Fix an integer overflow bug in avdt_msg_asmbl This is a backport of Iaa4d603921fc4ffb8cfb5783f99ec0963affd6a2 to rvc-dev Bug: 280633699 Test: manual Ignore-AOSP-First: security Tag: #security (cherry picked from https://googleplex-android-review.googlesource.com/q/commit:26347d4bdba646bbba4d27337d2888a04de42639) Merged-In: Iaa4d603921fc4ffb8cfb5783f99ec0963affd6a2 Change-Id: Iaa4d603921fc4ffb8cfb5783f99ec0963affd6a2 (cherry picked from commit 788961b7ff13f65dfc64e992a01fd5aa04596c5e)
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 all required packages. Otherwise, you can use the following apt-get list:
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 lib32z-dev libncurses5 \ libgl1-mesa-dev libxml2-utils xsltproc unzip liblz4-tool libssl-dev \ libc++-dev libevent-dev \ flatbuffers-compiler libflatbuffers1 \ openssl openssl-dev
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/system/bt
Install dependencies (require sudo access). This adds some Ubuntu dependencies and also installs GN (which is the build tool we're using).
cd ~/fluoride/bt build/install_deps.sh
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 follow the instructions in build/dpkg/README.txt.
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
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.
./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:
cd ~/fluoride/bt/out/Default ./bluetoothtbd -create-ipc-socket=fluoride
