Project Description

Currently kernel module signature be attached in the end of kernel module (ko file). Scott Bahling has raised that there have some benefits that kernel allows to load module with a separate signature file.

Current module signature is PKCS#7 format, I thought that it's not hard to do that. But we will need a new system call for this.

Goal for this Hackweek

Implement a proof of concept in hackweek 20.

Resources

Base on the latest kernel mainline.
