Super cool. Also, love reading high quality linux patches. I think many, myself previously included, are afraid to even read the kernel source as one thinks it must be super complex. Of course some parts really are. However, the code is honestly of such high quality. I also highly value that feeling of realizing something once thought 'arcane' was actually only made by other humans, and it is legal to go read it and learn from it.

Better tooling for kpatch would be nice tho
IIRC canonical makes patches for official ubuntu kernels but acts like a Chinese restaurant (closed kitchen, orders come in through a small hatch behind the counter)

Clever! I know some will say it's like closing the barn door after the horse left, but having this in place to mitigate future vulnerabilities will be handy.

ok, but what kind of nefarious use case will it enable if it is accessible to malfeasance.

I guess it could disable the killswitch

If I'm a malicious actor that gets root, can I killswitch the killswitch?

Once you’ve got root, you don’t need to exploit compromised code to do whatever you want.

you're on the other side of the secure door already

killswitch is to prevent you from gaining root
