Given the length of the patch, it would be nice to attribute it to its author. You could commit it with git commit --author="Mati Aharoni <muts@kali.org>" or at least mention its name and origin in the git commit message.

@rhertzog You're right, i force pushed the commit with the correct credits.

Thanks
