The creator of systemd (Lennart Poettering) has recently created a new company dedicated to bringing hardware attestation to open source software.
What might this entail? A previous blog post could provide some clues:
So, let’s see how I would build a desktop OS. The trust chain matters, from the boot loader all the way to the apps. This means all code that is run must be cryptographically validated before it is run. This is in fact where big distributions currently fail pretty badly. This is a fault of current Linux distributions though, not of SecureBoot in general.
If this technology is successful, the end result could be that we would see our Linux laptops one day being as locked down as an Iphone or Android device.
There are lots of others who are equally concerned about this possibility: https://news.ycombinator.com/item?id=46784572
I wonder if this would allow an anti-cheat system to get acceptable trust of a system without having to access ring 0.
Of course, we’d then need the OS / kernel images to be signed. I think most gamers run stock kernels anyway.
I just don’t want see the garbage that is the Android Play Store where apps refuse to run because we run an OS that isn’t profitable to Google.
