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.

    Short answer: no

    Long answer: only the most important things should even have such low-level access to the system. A fucking game is not in that category. Nooooooo

    I can’t wait until I am able to give random programs kernel access on my system! That doesn’t sound problematic in the least! After all, I have the fullest confidence that for companies developing anticheat, my security is their highest concern! /s

          He’s just being pedantic.

          Technically ‘ls’ has kernel access because it depends on system calls in order to produce its output.

          System calls are the mechanisms through which programs request services from the Linux kernel, allowing them to perform tasks like file management, process control, and device management. Any program that’s running on your machine has the access required to make syscalls and so you could say they have access to the kernel. They won’t have kernel-level privileges, so they can’t act as the kernel, but they do have access. Obviously the original user was referring to kernel anti-cheat modules which act as the kernel with all of the same privileges.

    I surely hope they never will, no user program should ever be allowed to run at kernel level, that’s what malware does.

    I personally avoid those kind of games, but those who won’t can dual-boot.

    Sure hope not. If I wanted to run rookits I’d just use Windows. Why bother with Linux?

    This is why I don’t want more Linux adoption and don’t understand people cheering every new user. We’re in a sweet spot where a lot of games enable userland anticheat while we don’t get kernel level ports (however they may be shipped doesn’t matter). The only thing that’ll come out of more adoption is kernel level anticheat ports that’ll probably work with a few corporate backed distros only and we’ll actually lose the games we have today. Because those will switch over the kernel level alternatives too.

    The only way I’d like Linux to be a generic multiplayer platform is server side anticheats. It is very obviously the way to go and we are seeing extremely slow adoption (e.g. Marvel Rivals).

      On one side, I’m one of those glad for people coming to Linux because Linux is truly fantastic and it can make your life easier on many things, I’m happy for them.

      On the other side, I share your concerns, because everything that gets adopted by the masses is inevitably subject to enshittification, I would never want that to happen to Linux.

      We should find a sweet middle-point tho I have no idea what that would be.

      TBH I’m not sure wider adoption would worsen things ? Gaming distros would probably ship bullshit anticheat modules by default while the others would not, or at most provide some documentation on how to opt in.

      I think it’s quite similar to the situation with NVIDIA proprietary drivers? (I don’t own a graphics card so I’m not super aware on this topic)

        My point is you would either have to run those modules on Linux or not play the games. Which is the same as running them on Windows or not play the games with the exception that you’d lose the games that run on Linux with userland anticheat now.

    AFAIK Microsoft have plans to block kernel level anti-cheat on Windows. After the CrowdSec issues last year, they’re rethinking which types of programs should even be allowed to run in kernel space.

    Edit: I was wrong. They actually want to increase what can be done in user mode, to reduce reliance on kernel mode code.

      They actually want to increase what can be done in user mode, to reduce reliance on kernel mode code.

      That’s basically what Apple did with macOS 11. They deprecated kernel extensions and replaced them with “system extensions”, and created new APIs so security tools, VPNs and such could function without kernel-level privileges.

        Thanks. I looked into it a bit more and it looks like they actually want to increase what can be done in userland, to reduce the reliance on kernel mode. That’s still a good solution, if things the anti-cheat code needs to do can be moved into userland.

    From technical point of view it is possible. eBPF already has almost everything needed for doing that. And I think it can be done with a simple LKM but if they want it included in the main tree I’m sure they’ll get some colorful email from Linus.

    It’s relatively trivial, you just need to write a kernel module. You’d just need/want to make it gpl so everything it does is fully audited and transparent. That’s not a problem, is it? Right?

    From a technical standpoint, you could argue that someone could create a fork of the kernel that spoofs the interface that the anticheat uses to make it ignore things. You can, of course, also do something similar in Windows, but security theatre never let practicality get in the way.

    I think its less a question of the technical feasibility, and more of an issue that we, as users, don’t want more closed-source blobs in our kernels. Meanwhile, the publishers insist that they can’t open-source their anti-cheat code; Their idea being that if we know what’s in it, it will be easier to bypass.

    Basically, one distro or a few(at most) may get anti-cheat integrated one day(like, say, SteamOS), but it will likely never be in your standard Linux kernal.

    They could go the rought of kernel modules, I would think, but for whatever reason, we’re still having this conversation.

      Valve also has server side anticheat in his games (Counter Strike or Deadlock). They are also against it.

      Kernel-level anticheats can be bypassed anyways, but they are the easy solution for the corps that want to sell their multiplayer game.

          If you want it to still be steam OS and compatible with games then you couldn’t use kernel.org kernels that’s the point.

          If a person stands to make a lot of money figuring out how to use a regular, non-anticheat kernel then they will do it. It would be a lot less difficult to do when the kernel code is open source.

          For anti-cheats, it isn’t the case, as with Windows, where you can semi-trust that the kernel isn’t lying. If an anti-cheat runs and wants to see what DMA devices are connected it uses the kernel to do that and it trusts that the kernel isn’t lying. You could trivially modify the Linux kernel’s source code to not list a specific card when asked by a kernel module.

    Absolutely nothing prevents somebody from writing a kernel level anticheat on Linux.

      It would need to be open source, distributing proprietary kernel modules is a nightmare that can cause the OS to fail to boot after every kernel update. An open source anticheat kernel module would probably be useless and easy to bypass.

        It doesn’t “need” to be anything. It could be a DKMS module that is mandatory for playing a game.

    It already works, but studios using anticheats that DO support Linux CURRENTLY don’t bother implementing it because we’re maaaaaybe 3% of the market on a good day, so they say “fuck it” and don’t expend a few dev hours to enable it because they see it as a pain to deal with v users who need it.

      AFAIK the current anticheat systems on Linux only run in userspace not at kernel level. This does mean Linux is theoretically easier to bypass compared to windows, some games just dont seem to want to take that risk. For as you said 3% of the market.

      I personally disagree with that stance though, because all it takes is a hardware device and all software anticheats are useless no matter the os (think a raspberry pi, and capture card). So anticheat is really a losing battle anyways.

        Yeah… Apex Legends dropped Linux support a while ago and that’s one of the reasons they cited; and tbf, there were publicly available Linux cheats that ran under proton.

        But there’s also loads of publicly available “external” cheats that run the way you described. Some run through a virtual machine even. It’s just not a robust solution for preventing cheating, and mostly hurts the legit Linux players.

      So true. And worse than that, we’re probably also the 3% most likely to skip buying a game that requires anti-cheat, anyway. Many of us are famously un-friendly toward closed source code running with invasive permissions.

      It’s a lot more than just “a few dev hours”. You need to invest in training your testers on Linux, potentially purchasing new hardware, invest in programmers that can deal with writing for Linux, etc… Just because something like BattlEye has a checkbox for Linux support doesn’t mean that all it takes is to click the button and rebuild your game.

    Meanwhile in indie land, I just tried to cheat my way through a Chapter 3 minigame in Deltarune, and Toby Fox himself showed up in his dogsona to blow up the game and make me start the minigame over.

    This is the extent to which anti-cheat measures should go.
