Linux Executable Basic Block Random Access Disassembly with Python3

Lexxeous's Python Basic Blocks:

Summary:

This program takes a Linux executable as an input, and optionally a list of values as manual basic block leader addresses, and disassembles the executable's .text section, at an assembly level, into all of its unique, basic logic blocks.

You can read more about basic blocks from the Wikipedia page.

How to Run:

You can run basic_blocks.py manually using:

python3 basic_blocks.py <executable_path> [space_separated_list_of_values]

where <executable_path> can also be `which <executable_name>`.

Using Make:

Alternatively, you can take advantage of the Makefile by using:

make <executable_name>

which will disassemble all of the basic blocks for an exacutable called <executable_name>.

To include a list of manual leaders, use:

make <executable_name> leaders=<value>\ <value>\ ... \ <value>

where the list of values is separated by escaped space characters "\ ".

Values in the leaders list represent addresses in the .text section of the chosen executable. The values must be within range and may be of formats hexidecimal or decimal integer.

Output Files:

The output of all basic blocks is to a file called basic_blocks.txt.

The .text section and the entire <explore> list is outputted to a file called text_section.txt.

Cleaning Up:

Using make clean will remove these two output files. They will be recreated upon running the program again.
