Functrace - A Function Tracer
functrace is a tool that helps to analyze a binary file with dynamic instrumentation using DynamoRIO (http://dynamorio.org/).
These are some implemented features (based on DynamoRIO):
- disassemble all the executed code
- disassemble a specific function (dump if these are addresses)
- get arguments of a specific function (dump if these are addresses)
- get return value of a specific function (dump if this is an address)
- monitors application signals
- generate a report file
- ghidra(https://ghidra-sre.org/) coverage script (based on the functrace report file)
Setup
$ wget https://github.com/DynamoRIO/dynamorio/releases/download/release_7_0_0_rc1/DynamoRIO-Linux-7.0.0-RC1.tar.gz
$ tar xvzf DynamoRIO-Linux-7.0.0-RC1.tar.gz
$ wget https://github.com/DynamoRIO/dynamorio/releases/download/cronbuild-7.91.18047/DynamoRIO-x86_64-Linux-7.91.18047-0.tar.gz
$ tar xvzf DynamoRIO-x86_64-Linux-7.91.18047-0.tar.gz
$ git clone https://github.com/invictus1306/functrace
$ mkdir -p functrace/build
$ cd functrace/build
$ cmake .. -DDynamoRIO_DIR=/full_DR_path/cmake/
$ make -j4
Using functrace
$ drrun -c libfunctrace.so -report_file report -- target_program [args]
Options
The following [functrace](https://github.com/invictus1306/functrace) options are supported:
-disassembly -> disassemble all the functions
-disas_func function_name -> disassemble only the function function_name
-wrap_function function_name -> wrap the function function_name
-wrap_function_args num_args -> number of arguments of the wrapped function
-cbr -> remove the bb from the cache (in case of conditional jump)
-report_file file_name -> report file name (required)
-verbose -> verbose
Simple usage
Option -verbose
$ drrun -c libfunctrace.so -report_file report -verbose -- target_program [args]
Option -disassemby
$ drrun -c libfunctrace.so -report_file report -disassembly -- target_program [args]
Option -disas_func
$ drrun -c libfunctrace.so -report_file report -disas_func name_function -- target_program [args]
Option -wrap_function and -wrap_function_args
$ drrun -c libfunctrace.so -report_file report -wrap_function name_function -wrap_function_args num_args -- target_program [args]
Option -cbr
$ drrun -c libfunctrace.so -report_file report -cbr -- target_program [args]
