GDB-Python script to trace calls to `malloc()` and `free()`

	# This script can print out the arguments and return values of `malloc()` and
	# `free()`, thanks to the power of GDB-Python.
	#
	# Usage: load the target program in gdb, wait until libc is loaded (e.g. by
	# executing `start`), then execute `source malloc-trace.py`, and enjoy!
	#
	# Note: this only works for Linux x86_64. Porting should not be difficult if
	# you are familiar with the C calling convention on the target platform.
	#
	# Also, feel free to extend this script with the functionalities you want (e.g.

Kernel pwn exploit submitter, useful in CTF competitions, optimized for larger binaries and better terminal interactions

	'''
	A kernel pwn exploit submitter, optimized for larger binaries and better terminal interactions.

	Best suitable when you have a large binary to send (>= 500 KiB), and other (non-chunked and
	non-flow-controlled) senders result in truncated and corrupted binaries.

	This normally runs at ~150 KiB/s for base64 encoded data, sufficient for use in CTF competitions.

	Requires python-pwntools to be installed.
