Fix integer overflow when parsing avrc response Convert min_len from 16 bits to 32 bits to avoid length checking overflow. Also, use calloc instead of malloc for list allocation since caller need to clean up string memory in the list items Bug: 242459126 Test: fuzz_avrc Tag: #security Ignore-AOSP-First: Security Merged-In: I7250509f2b320774926a8b24fd28828c5217d8a4 Change-Id: I7250509f2b320774926a8b24fd28828c5217d8a4 (cherry picked from commit 1b455b40fa104acb2527b351b80c3b5e66f79bfb) Merged-In: I7250509f2b320774926a8b24fd28828c5217d8a4
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
