SymBisect

To do

Feature

• handle some the Linux kernel functions, e.g., kmalloc()
• under constraint symbolic execution
• terminate state at low priority basic block and stop at target basic block, which could be set in config json
• handle indirect function call by MLTA default, also accept specify callee from config json
• easily expanded, just inherit class Listener and add it in function preparation()

Build

sudo apt install -y git cmake vim curl make unzip
sudo apt install -y autoconf automake libtool g++ build-essential pkg-config flex bison 
sudo apt install -y libgflags-dev libgtest-dev libc++-dev libssl-dev libelf-dev libsqlite3-dev

build with apt install llvm & z3 (sudo)

sudo apt install llvm-11 clang-11 z3
mkdir ./cmake-build
cd ./cmake-build
cmake -DCMAKE_BUILD_TYPE=Debug \
  -DLLVM_CONFIG_BINARY=/usr/bin/llvm-config-11 \
  -DENABLE_SOLVER_Z3=ON \
  -DENABLE_UNIT_TESTS=OFF \
  -DENABLE_SYSTEM_TESTS=OFF \
  -DENABLE_TCMALLOC=OFF \
  -DENABLE_DOXYGEN=OFF \
  -G "CodeBlocks - Unix Makefiles" \
  ..
make -j

build llvm & z3 & klee (no sudo)

export PATH_PROJECT=$PWD
mkdir $PATH_PROJECT/build
mkdir $PATH_PROJECT/install

# generate environment.sh
cd $PATH_PROJECT

echo "export PKG_CONFIG_PATH=$PATH_PROJECT/install/lib/pkgconfig:\$PKG_CONFIG_PATH" >> environment.sh
echo "export PATH_PROJECT=$PATH_PROJECT" >> environment.sh

Usage

klee --config=config.json

look at config.json to know more about the config json file.
