lol at that point you should argue to enable preempt_rt from userspace instead of kernelspace too

userspace vs kernelspace

ofc there's a ticking countdown on some of that, since those binary blobs in kernelspace are gonna have a lot fewer vulns going forward. but, well, there's still the human angle...

imo you're blackpilling too hard — fable is a file on a networked computer running kernelspace nvidia binary blobs operated by people without natsec security clearance. china no doubt has the file already. at some point they'll let someone distill release it; inverse silkworms

iirc this would make a ton of user to kernelspace jumps (at least, older iterations of this idea have) which will kill your round trip latency likely much, much slower than just regular swap on an SSD. modern linux is very optimized on async i/o

If I had to choose between: * commies inserting bugdoors into kernelspace, mesa, and openssl, or * My Opti OPL3-SA Sound Card and X not working without paying 4Front or Metro-Link money, I'm picking paying for closed-source X client and sound every day of the week.

Avatar² Watchmen Avatar² allows the user to hook various events during the orchestration. These hooks are user defined callbacks and allow to change or inspect the analyses state before or after the according event occurred. The first argument is the event to be hooked, the second argument specifies whether the callback shall be executed before or after the event is handled, and the third argument is a reference to the callback function to be executed. While all of the callbacks will get the avatar-instance passed as the first argument, additional arguments may be passed as well, as shown in the table. Quite notable, a lot of events will allow to inspect AvatarMessages. These are envelopes containing all important information about a specific event. These messages are normally generated by the targets' protocols and are passed to the avatar instance which dispatches them. github.com/avatartwo/avatar2… Avatar²: an open source binary firmware analysis framework 55 min video presentation  media.ccc.de/v/34c3-9195-ava… The Avatar project Improving embedded security with S²E, KLEE and Qemu Slide Presentation d/l s3.eurecom.fr/tools/avatar/b… EXTENDING DYNAMIC ANALYSIS FRAMEWORK AVATAR We implement automatic exploit generation for embedded systems firmwares, BY EXTENDING AN EXISTING DYNAMIC ANALYSIS FRAMEWORK CALLED AVATAR.

KernelScript 0.1 introduces an experimental type-safe DSL for writing eBPF, userspace, and kernelspace code from one codebase. linuxiac.com/kernelscript-0-… #Linux #Kernel #OpenSource

Sure lets say that, you can do harmful things to a machine from windows or linux kernelspace so might as well call them malware too I’m down for that i dont really mind its probably more accurate then too

the people complaining about this are ignorant boosting cpu freq for certain events is a common technique in envs where latency is important. your phones do this all the time. cpu boosts during touch events, app launch, camera shutter, etc. check out pixel’s libperfmgr for example (i forgot the name but caf/qcom has something similar in their power hal). it can even be done from kernelspace entirely for some events it’s clearly called low-latency mode and it’s clearly not on by default. shut up and let microsoft add something that isn’t copilot

Bedakan userspace dan kernelspace. Android meskipun pake kernel Linux, userlandnya beda dengan distro Linux pada umumnya.

My userspace solutions turned out to be ineffectively and unreliable, so I bit the bullet and went for the kernelspace solution. Binary patched the setxattr calls from Quarantine.kext out. Good-fucking-bye, com.apple.quarantine! Should have done that years ago.

Ho letto due cose al riguardo e benché abbia accessi preferenziali rispetto alle comuni applicazioni userspace, non ha componenti in kernelspace, almeno da quello che ho capito.

people in my comments 1. using slurs 2. in support of anti-cheat in kernelspace go ahead, lick the boot

anti-cheat does not need to run in kernelspace! good move from @PsyonixStudios

Diving deeper daily into @isovalent @ciliumproject eBPF, XDP, K8s And the Aya Rust implementations. Today's rabbit hole was all about perfbuf vs. ringbuf. Sharing data between userspace and kernelspace. Efficiency, data ordering, integrity- Study this #Rustlang

all we need now is to let claude run in kernelspace had a discussion about this with some people today actually and i think this could legitimately help w computer use (directly interfacing with quartz, winapi etc) problem being user adoption though (look at ring0 anticheats)

primarily the cost of copying the data and propagating from userspace to kernelspace and back

Lol, its been the general consensus that the current Kernelspace anticheat solutions need to be replaced for something that only runs in userspace, Valve entering into the console market with a PC nonetheless will change that, if the price of the Machine is enticing enough
