I've been slowly transitioning the TODO list to a github issue tracker here: https://github.com/KSPP/linux/issues/ > If you have any items not owned, please share me the info.

I'm not aware of anyone working on those currently, so they would be very welcome! :) Thanks for reaching out! -- Kees Cook
