# Description:
#
# This payload duplicates stdio, stdin and stderr to a file descriptor,
# stored on $s2, and executes /bin/sh.

# Assemble and create a relocatable object with:
# as -o stage_tcp_shell.o stage_tcp_shell.s
#
# Assemble, link and create an executable ELF with:
# gcc -o stage_tcp_shell stage_tcp_shell.s
#
# The tool "tools/metasm_shell.rb" can be used to easily
# generate the string to place on:
