"The new Linux kernel was released and it's kind of a big deal," writes longtime Slashdot reader rexx mainframe. "Here is what you can expect." Linuxiac reports: A key update in Linux 7.0 is the removal of the experimental label from Rust support. That (of course) does not make Rust a dominant language in kernel development, but it is still an important step in its gradual integration into the project. Another notable security-related change is the addition of ML-DSA post-quantum signatures for kernel module authentication, while support for SHA-1-based module-signing schemes has been removed. The kernel now includes BPF-based filtering for io_uring operations, providing administrators with improved control in restricted environments. Additionally, BTF type lookups are now faster due to binary search. At the same time, this release continues ongoing cleanup in the kernel's lower layers. The removal of linuxrc initrd code advances the transition to initramfs as the sole early-userspace boot mechanism. Linux 7.0 also introduces NULLFS, an immutable and empty root filesystem designed for systems that mount the real root later. Plus, preemption handling is now simpler on most architectures, with further improvements to restartable sequences, workqueues, RCU internals, slab allocation, and type-based hardening. Filesystems and storage receive several updates as well. Non-blocking timestamp updates now function correctly, and filesystems must explicitly opt in to leases rather than receiving them by default. Phoronix has compiled a list of the many exciting changes. Linus Torvalds himself announced the release, which can be downloaded directly from his git tree or from the kernel.org website. Linux 7.0 has a major new version number but it's "largely a numbering reset [...], not a sign of some unusually disruptive release," notes Linuxiac.

Booking.com says hackers accessed customer reservation data in a breach that may have exposed booking details, names, email addresses, phone numbers, addresses, and messages shared with accommodations. PCMag reports: On Sunday, users reported receiving emails from Booking.com, warning them that "unauthorized third parties may have been able to access certain booking information associated with your reservation." The email suggests the hackers have already exploited customer information. "We recently noticed suspicious activity affecting a number of reservations, and we immediately took action to contain the issue," Booking.com wrote. "Based on the findings of our investigation to date, accessed information could include booking details and name(s), emails, addresses, phone numbers associated with the booking, and anything that you may have shared with the accommodation." Amsterdam-based Booking.com has now generated new PINs for customer reservations to prevent hackers from accessing them. Still, the incident risks exposing affected customers to potential phishing scams. The Australian Broadcasting Corporation and several Reddit users say they received scam messages from accounts posing as Booking.com.

According to the Financial Times, Meta is developing an AI avatar of Mark Zuckerberg that could interact with employees using his voice, image, mannerisms, and public statements, "so that employees might feel more connected to the founder through interactions with it." The Verge reports: Meta may start allowing creators to make AI avatars of themselves if the experiment with Zuckerberg succeeds, according to the Financial Times. [...] Zuckerberg is involved in training the AI avatar, the Financial Times reports, and has also started spending five to 10 hours per week coding on Meta's other AI projects and participating in technical reviews.

It shouldn't be a surprise that companies - and for our field, technology companies specifically - working with the defense industry tends to raise eyebrows. With things like the genocide in Gaza, the threats of genocide and war crimes against Iran, the mass murder in Lebanon, it's no surprise that western companies working with the militaries and defense companies involved in these atrocities are receiving some serious backlash. With that in mind, it seems Red Hat, owned by IBM, is desperately trying to scrub a certain white paper from the internet. Titled "Compress the kill cycle with Red Hat Device Edge", the 2024 white paper details how Red Hat's products and technologies can make it easier and faster to, well, kill people. Links to the white paper throw up 404s now, but it can still easily be found on the Wayback Machine and other places. It's got some disturbingly euphemistic content. The find, fix, track, target, engage, assess (F2T2EA) process requires ubiquitous access to data at the strategic, operational and tactical levels. Red Hat Device Edge embeds captured, analyzed, and federated data sets in a manner that positions the warfighter to use artificial intelligence and machine learning (AI/ML) to increase the accuracy of airborne targeting and mission-guidance systems. Delivering near real-time data from sensor pods directly to airmen, accelerating the sensor-to-shooter cycle. Sharing near real-time sensor fusion data with joint and multinational forces to increase awareness, survivability, and lethality. The new software enabled the Stalker to deploy updated, AI-based automated target recognition capabilities. If the target is an adversary tracked vehicle on the far side of a ridge, a UAS carrying a server running Red Hat Device Edge could transmit video and metadata directly to shooters. ↫ Red Hat white paper titled "Compress the kill cycle with Red Hat Device Edge" I don't think there's something inherently wrong with working together with your nation's military or defense companies, but that all hinges on what, exactly, said military is doing and how those defense companies' products are being used. The focus should be on national defense, aid during disasters, and responding to the legitimate requests of sovereign, democratic nations to come to their defense (e.g. helping Ukraine fight off the Russian invasion). There's always going to be difficult grey areas, but any military or defense company supporting the genocide in Gaza or supplying weapons to kill women and children in Iran is unequivocally wrong, morally reprehensible, and downright illegal on both an international and national level. It clearly seems someone at Red Hat feels the same way, as the company has been trying really hard to memory-hole this particular white paper, and considering its word choices and the state of the world today, it's easy to see why. Of course, the internet never forgets, and I certainly don't intend to let something like this slide. We all know companies like Microsoft, Oracle, and Google have no qualms about making a few bucks from a genocide or two, but it always feels a bit more traitorous to the cause when it's an open source company doing the profiting. It feels like Red Hat is trying to have its cake and eat it too, by, as an IBM subsidiary, trying to both profit from the vast sums of money sloshing around in the US military industrial complex as well as maintain its image as a scrappy open source business success story shitting bunnies and rainbows. It's a long time ago now that Red Hat felt like a genuine part of the open source community. Most of us - both outside and inside of Red Hat, I'm sure - have been well aware for a long time now that those days are well behind us, and I guess Red Hat doesn't like seeing its kill cycle this compressed.

If you want to run FreeBSD on a laptop, you're often yanked back to the Linux world of 20 years ago, with many components and parts not working and other issues such as sleep and wake problems. FreeBSD has been hard at work improving the experience of using FreeBSD on laptops, and now this has resulted in a list of laptops which work effortlessly with the venerable operating system. There's only about 10 laptops on the list so far, but they do span a range of affordability and age, with some of them surely being quite decent bargains on eBay or whatever other used stuff marketplace you use. If you want to use FreeBSD on a laptop, but don't want to face any surprises or do any difficult setup, get one of the laptops on this list - a list which will surely expand over time.

It may sound unbelievable to some, but not everyone has a datacenter beast with 128GB of VRAM shoved in their desktop PCs. Around the world people tell the tale of a particularly fierce group of Linux gamers: Those who dare attempt to play games with only 8 gigabytes of VRAM, or even less. Truly, it takes exceedingly strong resilience and determination to face the stutters and slowdowns bound to occur when the system starts running low on free VRAM. Carnage erupts inside the kernel driver as every application fights for as much GPU memory as it can hold on to. Any game caught up in this battle for resources will surely not leave unscathed. That is, until now. Because I fixed it. ↫ Natalie Vock The solution is to use cgroups to control the kernel's memory eviction policies, so that applications that should get priority when it comes to VRAM allocation - like games - don't get their memory evicted from VRAM to system RAM. Basically, evict everything else from VRAM before touching the protected application. This way, something like a game will have much more consistent access to more VRAM, thereby reducing needless memory evictions that harm performance. It's a clever solution that makes use of a ton of existing Linux tools, meaning it's also much easier to upstream, implement, and support. Excellent work.
