voidwalker 0.1.0

A GDB toolbox for low-level debugging

(void)walker is a toolbox for GDB which provides utilities for debugging software on an instruction level.

Requirements

• GDB 7.5 or later built with support for Python extensions.

• FlowUI 0.2.1 or later.

Currently (void)walker has support for the following architectures:

* X86
* X86-64
* MIPS

Usage

(void)walker can be loaded manually from within GDB by running:

python from voidwalker import voidwalker

By adding the previous line to ~/.gdbinit (void)walker will be loaded automatically whenever GDB is launched.

Also register the following hooks in ~/.gdbinit:

define hook-stop
    voidwalker hook-stop
end

Commands

Here follows a list of a few commands, see the README for a complete list.

Dumping the context of the current stack frame:

Dumping data by specifying address and length:

voidwalker dump data <address> <length>

Dumping disassembly by specifying address and the number of instructions:
