I’m having a hard time understanding how this would work. udev will load kernel modules depending on your hardware, and these modules run in kernel space. Is there an assumption that a kernel module can’t cheat? Or do they have a checksum for each possible kernel module that can be loaded?
Also, how do they read the kernel space code? Userspace can’t do this afaik. Do they load a custom kernel module to do this? Who says it can’t just be replaced with a module that returns the “right” checksum?
For example, maybe branching is something you’d like to be able to do without it being a nightmare?
Services are automatically restarted. There is no automatic reboot by default, but that can be enabled if you really want to. Otherwise it’ll keep track of whether a reboot is necessary or not.
I’ve been running Debian stable with unattended-upgrades on servers for years and have had no issues whatsoever.
That joke has aged like milk
I expected some resolution or motivation for everything that had occurred, instead we got “God did it”.
It’s just a pity on a great show to have such a bad ending.
I’ve used LyX with good results, it’s a GUI that abstracts away many of the complexities of latex.
Unless there are security updates to install, then everything will be mercilessly killed
I think you commented on the wrong post Edit: nevermind, these are spam links that they bypass the spam filter by starting with some random text.
Word. First thing that gets installed by me on any windows install.
I have a 10 year old Canon MP280 still going strong. It’s one of the ultra cheap ones, I believe originally sold for something like 20$ at a sale. The only problem it has nowadays is that it occasionally makes some ink blotches in a corner of the page.
separate processor with hundreds of cores
Well, graphics rendering is very suited for parallelism. That’s why GPUs were invented.
Most other tasks are not. Most of the cores in a 128-core JPU would end up being unused. Also why JPU? It’s not like it’s significantly different from a normal CPU task.
They meant the command dtrx, the combination of dtrx as parameters to tar make no sense. Extract AND append?
Then comes a .tar.bz2 file along and you’re screwed. xtract je vucking file?
Pro tip: -z, -j are not needed by tar anymore since many years, tar will autodetect what compression was used if your distro is anything remotely modern.
Look up preemptive task scheduling. Basic processes will get interrupted after using a too long time slice.
Is there a 6502 backend?
Yeah it’s many years that I haven’t had to specify z, j etc.
Ah, so they don’t actually say that they read kernel space. They check the version of all installed packages and checksum the installed DLLs/SOs.
If the user still has root privileges, this may still not prevent sideloading of kernel modules. Even if it would detect a kernel module that has been sideloaded, I believe it’s possible to write a kernel module that will still be resident after you unload it. This kernel module can then basically do anything without the knowledge of userspace. It could for example easily replace any code running in userspace, and their anticheat would miss that as it doesn’t actually check what code is currently running. Most simply, code could be injected that skips the anticheat.
Of course, in their model, if a user isn’t given root privileges it seems much harder to do anything, then probably the first thing you’d want to look for is a privilege escalation attack to obtain root privileges. This might not be that hard if they for example run Xorg as it isn’t known to be the most secure - there’s a reason there’s a strong recommendation to not run any graphical UI on servers.
Another way if you don’t have root is to simply run the code on a system that does but that does have such a kernel module - or perhaps modify the binary itself to skip the anticheat. I don’t see anything preventing that in their scheme.
