From both a technical perspective and if the maintainers of these anti-cheat will consider porting or re-writing kernel level anti-cheat to work on linux, is it possible? Do you think that the maintainers of kernel level anti-cheat will be adamant in not doing it, or that the kernel even supports it or will support it. I think that if it ever happens, there will be a influx of people moving to linux, or abandoning their duelboots, and that alot of people will hate that such a thing is available on linux.

    I’m not a programmer or cheater or anything, but I think the answer is yes and no. Yes it could technically be done and even work as intended as long as the device is locked down to prevent the user from replacing the shipped kernel (which would be a bad thing for users). However, savvy people could (in theory) make custom kernels that lie to the kernel module, causing the module to report there is no cheating when there is. It’s my understanding that it’s close to the current situation with Windows and virtual machines and anticheat: you can cheat by running your game in a VM and then have that virtual hardware extract secret information or flip bits in the right spots. Most competitive games will refuse to run in a VM for this reason.

      Kernel level anti cheats require secure boot. You can’t just “lie” and load an unsigned kernel.

      This is where TPMs, measured boot, and remote attestation come in.

      You can run whatever kernel you want, but if it is not an approved kernel, you wouldn’t be able to attest to running an approved kernel; allowing whatever DRM scheme the developer put in to active.

      I believe this is how the higher levels of Android’s Play Integrity system work.
