Long-time Slashdot reader internet-redstar writes: In little longer than 1 year, RHEL7 and CentOS 7 will go EOL. Large enterprises with thousands of these servers are struggling to meet that deadline. Now they also have the option to use Project78 from Linux Belgium which offers a Cloud and OnPrem version to aid in the transition to RHEL 8 or Rocky Linux 8. It promises a 100% success rate for in-place OS upgrading and a 95% success rate for application migrations in a Upgrade-as-a-Service package.
In April Red Hat's senior technical marketing manager shared their thoughts about next year's end of life for CentOS Linux and the End-of-Maintenance for Red Hat Enterprise Linux 7 (along with some tips): The good news is that these events won't require a complete infrastructure overhaul. Tools are available to move from your current configuration to a place where you'll have years of support. While June of '24 may sound a ways off, do not delay. It will be here faster than you think. Start planning now. Start moving soon. Give yourself plenty of runway, and don't forget that we aren't just your software vendor at Red Hat. We are your partners and are here to help you with these transitions.
UPDATE (7/3): Thursday Red Hat announced an add-on option for four more years of "extended support" for RHEL 7: As we near the end of the standard 10-year life cycle of RHEL 7, some IT organizations are finding that they cannot complete their planned migrations before June 30, 2024. To support IT teams while they catch up on their migration schedules, Red Hat is announcing a one-time, 4 year ELS maintenance period for RHEL 7 ELS. While Red Hat is providing more time, we strongly recommend customers migrate to a newer version of RHEL to take advantage of new features and enhancements...

For organizations that need to remain on a major release beyond the standard life cycle, we offer the Extended Life Cycle Support (ELS) Add-On. This add-on currently extends support of major releases for up to 2 years after the end of the standard release life cycle. As an optional, add-on subscription, ELS gives you access to troubleshooting for the last minor release, selected urgent priority bug fixes and certain Red Hat-defined security fixes...

ELS for RHEL 7 is now available for 4 years, starting on July 1, 2024. Organizations must be on RHEL 7.9 to take advantage of this. Compared to previous major releases, ELS for RHEL 7 (RHEL 7.9) expands the scope of security fixes by including updates that address Important CVEs. It also includes maintenance for Red Hat Enterprise Linux for SAP Solutions and Red Hat Enterprise Linux High Availability and Resilient Storage add-ons. And to help you create your long-term IT infrastructure strategy, Red Hat plans to offer ELS for 3 years for both RHEL 8 and 9.

When you're ready to upgrade from RHEL 7 — or any other version — Red Hat is here to help. We offer in-place upgrade tools and detailed guidance to streamline upgrades and application migrations. You can also engage Red Hat Consulting to plan and execute your upgrade projects.

"CentOS Stream will now be the sole repository for public RHEL-related source code releases..." Red Hat posted this week on its blog, arguing that "The engagement around CentOS Stream, the engineering levels of investment, and the new priorities we're addressing for customers and partners now make maintaining separate, redundant, repositories inefficient."

Long-time Slashdot reader slack_justyb notes this means patches and changes will now hit CentOS Stream before actually hitting RHEL, which "will make it difficult for other distributions such as Alma Linux, Rocky Linux, and Oracle Linux to provide assured binary compatibility as their only source now will be ahead of what RHEL is actually using."

"Some commentators are pointing out that it's possible to sign up for a free Red Hat Developer account, and obtain the source code legitimately that way," writes the Register. "This is perfectly true, but the problem is that the license agreement that you have to sign to get that account prevents you from redistributing the software." Hackaday notes that beyond the the GPL v2 license on the kernel, Red Hat also has "an additional user agreement that terminates access to updates if the code is re-published."

Rocky Linux officially "remains confident in its ability to continue as a bug-for-bug compatible and freely available alternative to Red Hat Enterprise Linux, despite changes in accessibility." While this decision does change the automation we use for building Rocky Linux, we have already created a short term mitigation and are developing the longer term strategy. There will be no disruption or change for any Rocky Linux users, collaborators, or partners... The project pledges to keep its promise to maintain the full life-span of support for Rocky 8 and 9, and to continue to produce future RHEL-compatible versions as long as the option remains, allowing organizations to maintain the flexibility, control, and freedom they rely upon for their critical infrastructure. This is the open source way.
Gregory Kurtzer, founder of the Rocky Linux project, calls Red Hat's move "a minor inconvenience for the Rocky Linux team," but with "no disruption to Rocky Linux users. Moving forward we are becoming even more stable, supported, and secure."

AlmaLinux also weighs in: Can you just use CentOS Stream sources?
No, we are committed to remaining a downstream RHEL clone, and using CentOS Stream sources would make us upstream of RHEL. CentOS Stream sources, while being upstream of RHEL, do not always include all patches and updates that are included in RHEL packages.

Is Red Hat trying to kill downstream clones?
We cannot speak to Red Hat's intentions, and can only point to the things they have said publicly. We have had an incredible working relationship with Red Hat through the life of AlmaLinux OS and we hope to see that continue.

SUSE's latest release of SUSE Linux Enterprise 15 Service Pack 5 (SLE 15 SP5) has a focus on security, claiming it as the first distro to offer full support for confidential computing to protect data. From a report: According to SUSE, the latest version of its enterprise platform is designed to deliver high-performance computing capabilities, with an inevitable mention of AI/ML workloads, plus it claims to have extended its live-patching capabilities. The release also comes just weeks after the community release openSUSE Leap 15.5 was made available, with the two sharing a common core. The Reg's resident open source guru noted that Leap 15.6 has now been confirmed as under development, which implies that a future SLE 15 SP6 should also be in the pipeline.

SUSE announced the latest version at its SUSECON event in Munich, along with a new report on cloud security issues claiming that more than 88 percent of IT teams have reported at least one cloud security incident over the the past year. This appears to be the justification for the claim that SLE 15 SP5 is the first Linux distro to support "the entire spectrum" of confidential computing, allowing customers to run fully encrypted virtual machines on their infrastructure to protect applications and their associated data. Confidential computing relies on hardware-based security mechanisms in the processor to provide this protection, so enterprises hoping to take advantage of this will need to ensure their servers have the necessary support, such as AMD's Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP) and Intel's Trust Domain Extensions (TDX).

Long-time Slashdot reader waspleg shared this story from Hot Hardware: Red Hat Linux developer Richard WM Jones has shared an eyebrow raising tale of Linux bug hunting. Jones noticed that Linux 6.4 has a bug which means it will hang on boot about 1 in 1,000 times. Jones set out to pinpoint the bug, and prove he had caught it red handed. However, his headlining travail, involving booting Linux 292,612 times (and another 1,000 times to confirm the bug) apparently "only took 21 hours." It also seems that the bug is less common with Intel hardware than AMD based machines.

Slashdot reader e065c8515d206cb0e190 shared the big announcement from Debian.org: After 1 year, 9 months, and 28 days of development, the Debian project is proud to present its new stable version 12 (code name bookworm).

bookworm will be supported for the next 5 years thanks to the combined work of the Debian Security team and the Debian Long Term Support team...

This release contains over 11,089 new packages for a total count of 64,419 packages, while over 6,296 packages have been removed as obsolete. 43,254 packages were updated in this release. The overall disk usage for bookworm is 365,016,420 kB (365 GB), and is made up of 1,341,564,204 lines of code.

bookworm has more translated man pages than ever thanks to our translators who have made man-pages available in multiple languages such as: Czech, Danish, Greek, Finnish, Indonesian, Macedonian, Norwegian (Bokmål), Russian, Serbian, Swedish, Ukrainian, and Vietnamese. All of the systemd man pages are now completely available in German.

The Debian Med Blend introduces a new package: shiny-server which simplifies scientific web applications using R. We have kept to our efforts of providing Continuous Integration support for Debian Med team packages. Install the metapackages at version 3.8.x for Debian bookworm.

The Debian Astro Blend continues to provide a one-stop solution for professional astronomers, enthusiasts, and hobbyists with updates to almost all versions of the software packages in the blend. astap and planetary-system-stacker help with image stacking and astrometry resolution. openvlbi, the open source correlator, is now included.

Support for Secure Boot on ARM64 has been reintroduced: users of UEFI-capable ARM64 hardware can boot with Secure Boot mode enabled to take full advantage of the security feature.
9to5Linux has screenshots, and highlights some new features: Debian 12 also brings read/write support for APFS (Apple File System) with the apfsprogs and apfs-dkms utilities, a new tool called ntfs2btrfs that lets you convert NTFS drives to Btrfs, a new malloc implementation called mimalloc, a new kernel SMB server called ksmbd-tools, and support for the merged-usr root file system layout...

This release also includes completely new artwork called Emerald, designed (once again) by Juliette Taka. New fonts are also present in this major Debian release, along with a new fnt command-line tool for accessing 1,500 DFSG-compliant fonts.
Debian 12 "bookworm" ships with several desktop environments, including:

• Gnome 43,
• KDE Plasma 5.27,
• LXDE 11,
• LXQt 1.2.0,
• MATE 1.26,
• Xfce 4.18

Linux computer vendor System76 shared some news in a recent blog post. "We prefer to disable the Intel Management Engine wherever possible to reduce the amount of closed firmware running on System76 hardware. We've resolved a coreboot bug that allows the Intel ME (Management Engine) to once again be disabled."

Phoronix reports that the move will "benefit their latest Intel Core 13th Gen 'Raptor Lake' wares as well as prior generation devices." Intel ME is disabled for their latest Raptor lake laptops and most older platforms with some exceptions like where having a silicon issue with Tiger Lake. System76 has also added a new firmware setup menu option for enabling/disabling UEFI Secure Boot. The motivation here with making it easier to toggle Secure Boot is for allowing Windows 11 support with SB active while running System76 Open Firmware.

The Red Hat Package Managers for LibreOffice "have recently been orphaned," according to a post by Red Hat manager Matthias Clasen on the "LibreOffice packages" mailing list, "and I thought it would be good to explain the reasons behind this." The Red Hat Display Systems team (the team behind most of Red Hat's desktop efforts) has maintained the LibreOffice packages in Fedora for years as part of our work to support LibreOffice for Red Hat Enterprise Linux. We are adjusting our engineering priorities for RHEL for Workstations and focusing on gaps in Wayland, building out HDR support, building out what's needed for color-sensitive work, and a host of other refinements required by Workstation users. This is work that will improve the workstation experience for Fedora as well as RHEL users, and which, we hope, will be positively received by the entire Linux community.

The tradeoff is that we are pivoting away from work we had been doing on desktop applications and will cease shipping LibreOffice as part of RHEL starting in a future RHEL version. This also limits our ability to maintain it in future versions of Fedora.

We will continue to maintain LibreOffice in currently supported versions of RHEL (RHEL 7, 8 and 9) with needed CVEs and similar for the lifetime of those releases (as published on the Red Hat website). As part of that, the engineers doing that work will contribute some fixes upstream to ensure LibreOffice works better as a Flatpak, which we expect to be the way that most people consume LibreOffice in the long term.

Any community member is of course free to take over maintenance, both for the RPMs [Red Hat Package Managers] in Fedora and the Fedora LibreOffice Flatpak, but be aware that this is a sizable block of packages and dependencies and a significant amount of work to keep up with.
Commenters on LWN.net are now debating its impact.

One pointed out that "You will still find it in GNOME Software, which will install a Flatpak from FlatHub rather than an RPM from the distro."

motang writes: Canonical, the sponsor of widely popular Ubuntu Linux, plans on shipping the next LTS in two versions. In addition to the traditional version, there will be one immutable desktop OS flavor. From Canonical blog: The technology behind snaps extends beyond the distribution of desktop applications however. With Ubuntu Core this philosophy of security and stability applies equally to the components that make up the entire Ubuntu operating system. Rather than treating the OS as a single immutable 'blob,' Ubuntu Core breaks it up into discrete components. The base of Ubuntu Core, for example, is built on four primary snaps:

Gadget: Defines the system's bootloader, partition layout and default configurations for snaps.
Kernel: Containing the Linux kernel and hardware drivers.
Base: A minimal Ubuntu OS image containing only the necessary services and utilities to support the applications running on top.
Snapd: Manages the lifecycle of all snaps in an Ubuntu Core system.
Additional OS snaps can then be layered onto this image to enable other elements of the operating system such as a desktop environment.

When Red Hat laid off 4% of its global staff, Fedora Program Manager Ben Cotton was "a member of that 4%," according to a new post on Cotton's blog: I've received so much support from people since the news started spreading. It's like that end scene of "It's a Wonderful Life" and I'm George Bailey. I'm proud of the contributions I've made to the Fedora community over the last five years, and it feels good to have others recognize that.
Cotton joined Red Hat in 2018, but "I was a Fedora contributor long before" Cotton writes, adding later that "I fully intend to still be participating in the Fedora community when my account hits the 20-year mark in May 2029." (Cotton's first foray into Fedora was joining its Docs team in 2009, and then volunteering to be the Docs project leader in 2011...)

And the blog post adds that professionally Cotton is "already pursuing a few opportunities... In the meantime, I have (at least) a few weeks to relax for a bit." I've told folks that if Fedora falls off the rails, then I have failed. I'm working with Matthew, Justin, and others to ensure coverage of the core job duties one way or another. I've worked hard over the years to automate tasks that can be automated. The documentation is far more comprehensive than what I inherited. No doubt there are gaps in what I've left for my successors. However, my goal is that in a few months, nobody will notice that I'm gone. That's my measure of success...

As to what the broader implication behind the loss of my position might be, I don't know. There's no indication that my role was targeted specifically. There are definitely people in Red Hat who continue to view Fedora as strategically important.

ZDNet reports that Jim Zemlin, executive director at the Linux Foundation, recently noted rounds of tech-industry layoffs "in the name of cost-cutting." But then Zemlin added that "open source is countercyclical to these trends. The Linux Foundation itself, for instance, had its best first quarter ever."

As Hilary Carter, SVP of research and communications at the Linux Foundation, said in her keynote speech at Open Source Summit North America in Vancouver, Canada: "In spite of what the headlines are saying, the facts are 57% of organizations are adding workers this year." Carter was quoting figures from the Linux Foundation's latest job survey, which was released at the event.

Other research also points to brighter signs in tech employment trends. CompTIA's recent analysis of the latest Bureau of Labor Statistics (BLS) data suggests the tech unemployment rate climbed by just 2.3% in April. In fact, more organizations plan to increase their technical staff levels rather than decrease.

The demand for skilled tech talent remains strong, particularly in fast-developing areas, such as cloud and containers, cybersecurity, and artificial intelligence and machine learning. So, what do these all areas of technology have in common? The answer is they're all heavily dependent on open source and Linux technologies.
While layoffs are happening at Microsoft, Amazon, Google, IBM, and even Red Hat, "the Linux Foundation found senior technical roles are seeing the biggest cuts," the article points out. "New hiring is focused on developers and IT managers." And companies are also spending more on training for existing technical staff, "driven by the fact that there aren't enough experts in hot technologies, such as Kubernetes and generative AI, to go around." Interestingly, a college degree is no longer seen as such a huge benefit. Businesses responding to the Linux Foundation's research felt upskilling (91%) and certifications (77%) are more important than a university education (58%) when it comes to addressing technology needs.

Roblox's new anti-cheat software puts a stop to in-game exploits, but at what cost? According to Liam Dawe from Gaming On Linux, it's blocking the Wine application, meaning "you won't be able to play it on Linux any more, at all, unless you find some sort of special workaround." He adds: "Previously the roll-out of this update was being tested only with some users. Now though it's here for everyone giving a 64 bit client and introducing their Hyperion anti-cheat software which they are intentionally blocking Wine with." Here's what one of their staff had to say about this: Hi - thanks for the question. I definitely get where you're coming from, and as you point out, you deserve a clear, good-faith answer. Unfortunately that answer is essentially "no."

From a personal perspective, a lot of people at Roblox would love to support Linux (including me). Practically speaking, there's just no way for us to justify it. If we release a client, we have to support it, which means QA, CS, documentation, etc., all of which is much more difficult on a fragmented platform. We release weekly on a half-dozen platforms. Adding in the time to test, debug, and release a Linux client would be expensive, which means time taken away from improving Roblox on our current platforms.

Even Wine support is difficult because of anti-cheat. As wonderful as it would be to allow Roblox under Wine, the number of users who would take advantage of that is minuscule compared with our other platforms, and it's not worthwhile if it makes it easy for exploiters to cheat.

I'm sorry to be such a downer about this, but it's the reality. We have to spend our time porting to and supporting the platforms that will grow our community.

Again, I'm personally sorry to have to say this. Way back in 2000 I had a few patches accepted into the kernel, and I led the port of Roblox game servers from Windows to Linux several years ago. From a technical and philosophical perspective, it would be a wonderful thing to do. But our first responsibility is to our overall community, and the opportunity cost of supporting a Linux client is far, far too high to justify.

Last week Linus Torvalds personally cleaned up the x86 memory copy code for Linux 6.4, Phoronix reports — and this week "he's merged more of his own code as he took issue with some of the code merged by Intel engineers as part of their Linear Address Masking enabling." Back during the Linux 6.2 days at the end of last year, Linus rejected the Intel LAM code at the time for various technical issues. Intel then reworked it for Linux 6.4. This time around Linus merged Intel LAM into Linux 6.4 as this new CPU feature for letting user-space store metadata within some bits of pointers without masking it out before use. Intel LAM — like Arm TBI — can be of use to virtual machines, profiling / sanitizers / tagging, and other applications. But this time around there were some less than ideal code that he personally took to sprucing up...

Torvalds reworked around one hundred lines of code for cleaning it up.
It's fun to read Torvalds' commit messages (included in both Phoronix articles). Torvalds begins by writing that the LAM updates "made me unhappy about how 'access_ok()' was done, and it actually turned out to have a couple of small bugs in it too..."

Phoronix reports: With the financial backing of Amazon Web Services, sudo and su are being rewritten in the Rust programming language in order to increase the memory safety for the widely relied upon software... to further enhance Linux/open-source security.
"[B]ecause it's written in C, sudo has experienced many vulnerabilities related to memory safety issues," according to a blog post announcing the project: It's important that we secure our most critical software, particularly from memory safety vulnerabilities. It's hard to imagine software that's much more critical than sudo and su.

This work is being done by a joint team from Ferrous Systems and Tweede Golf with generous support from Amazon Web Services. The work plan is viewable here. The GitHub repository is here.

For Red Hat's 30th anniversary, North Carolina's News & Observer newspaper ran a special four-part series of articles.

In the first article Red Hat co-founder Bob Young remembers Red Hat's first big breakthrough: winning InfoWorld's "OS of the Year" award in 1998 — at a time when Microsoft's Windows controlled 85% of the market. "How is that possible," Young said, "that one of the world's biggest technology companies, on this strategically critical product, loses the product of the year to a company with 50 employees in the tobacco fields of North Carolina?" The answer, he would tell the many reporters who suddenly wanted to learn about his upstart company, strikes at "the beauty" of open-source software.

"Our engineering team is an order of magnitude bigger than Microsoft's engineering team on Windows, and I don't really care how many people they have," Young would say. "Like they may have thousands of the smartest operating system engineers that they could scour the planet for, and we had 10,000 engineers by comparison...."

Young was a 40-year-old Canadian computer equipment salesperson with a software catalog when he noticed what Marc Ewing was doing. [Ewing was a recent college graduate bored with his two-month job at IBM, selling customized Linux as a side hustle.] It's pretty primitive, but it's going in the right direction, Young thought. He began reselling Ewing's Red Hat product. Eventually, he called Ewing, and the two met at a tech conference in New York City. "I needed a product, and Marc needed some marketing help," said Young, who was living in Connecticut at the time. "So we put our two little businesses together."

Red Hat incorporated in March 1993, with the earliest employees operating the nascent business out of Ewing's Durham apartment. Eventually, the landlord discovered what they were doing and kicked them out.
The four articles capture the highlights. ("A visual effects group used its Linux 4.1 to design parts of the 1997 film Titanic.") And it doesn't leave out Red Hat's skirmishes with Microsoft. ("Microsoft was owned by the richest person in the world. Red Hat engineers were still linking servers together with extension cords. ") "We were changing the industry and a lot of companies were mad at us," says Michael Ferris, Red Hat's VP of corporate development/strategy. Soon there were corporate partnerships with Netscape, Intel, Hewlett-Packard, Compaq, Dell, and IBM — and when Red Hat finally goes public in 1999, its stock sees the eighth-largest first-day gain in Wall Street history, rising in value in days to over $7 billion and "making overnight millionaires of its earliest employees."

But there's also inspiring details like the quote painted on the wall of Red Hat's headquarters in Durham: "Every revolution was first a thought in one man's mind; and when the same thought occurs to another man, it is the key to that era..." It's fun to see the story told by a local newspaper, with subheadings like "It started with a student from Finland" and "Red Hat takes on the Microsoft Goliath."

Something I'd never thought of. 2001's 9/11 terrorist attack on the World Trade Center "destroyed the principal data centers of many Wall Street investment banks, which were housed in the twin towers. With their computers wiped out, financial institutions had to choose whether to rebuild with standard proprietary software or the emergent open source. Many picked the latter." And by the mid-2000s, "Red Hat was the world's largest provider of Linux...' according to part two of the series. "Soon, Red Hat was servicing more than 90% of Fortune 500 companies." By then, even the most vehement former critics were amenable to Red Hat's kind of software. Microsoft had begun to integrate open source into its core operations. "Microsoft was on the wrong side of history when open source exploded at the beginning of the century, and I can say that about me personally," Microsoft President Brad Smith later said.

In the 2010s, "open source has won" became a popular tagline among programmers. After years of fighting for legitimacy, former Red Hat executives said victory felt good. "There was never gloating," Tiemann said.

"But there was always pride."
In 2017 Red Hat's CEO answered questions from Slashdot's readers.

Linux Magazine argues that System76's Pop!_OS offers "something rare: a commercial distribution that was integrated into the hardware, with utilities designed specifically for System76 computers and keyboards." The only other example of an integrated commercial distro of which I am aware is Purism, a company in the same niche... With hardware and software coming from the same source — what business calls vertical integration — distributions like System76/Pop!_OS offer Linux users their first experiences with what Windows and macOS users have always enjoyed — to say nothing of the closest they can currently get to open hardware. Could Linux be finally becoming mainstream at last?
They interviewed System76 CEO Carl Richell (along with a marketing director and media relations manager), who remembered how System76 was actually founded in Carl's basement around 2005: He wanted to show the world how far Linux and open source software had come by delivering it preinstalled on high-quality computers backed by caring, knowledgeable customer support. Carl felt that making Linux computers that highlight the work of the community would be a great way to introduce the broader public to open source technology and its potential...

LM: What other hardware might System76 offer in the future?

S76: We are in the research and development process of designing our own in-house laptop. We'll eventually refresh our Meerkat mini desktop with a new Thelio-style aesthetic. That project will start sometime after our first in-house laptops start shipping. [In addition,] Launch keyboards and the System76 Keyboard Configurator work on macOS and Windows! We've also prepared ISO layouts for most Launch models but don't have a time frame for release.

LM: What are you willing to say at this point about the company's future directions?

S76: We're developing COSMIC DE — a desktop environment written in Rust — as well as a prototype for an open hardware laptop manufactured in-house. Finally, Nebula, a line of computer cases based on Thelio desktops will be arriving in the coming months.
My favorite line from the interview? "Seeing a flat sheet of aluminum transformed into a beautiful desktop is strikingly rewarding."

A new set of patches have been released for the Intel Linux graphics driver that "can provide 10-15% better performance when operating in the tuned mode," reports Phoronix. From the report: The set of Intel i915 Linux kernel graphics driver patches are about exposing the Intel RPS (Requested Power State) up/down thresholds. Right now the Intel Linux kernel driver has static values set for the up/down thresholds between power states while these patches would make them dynamically configurable by user-space. Google engineer Syed Faaiz Hussain raised the issue that they experimented with the Intel RPS tuning and were able to manage up to 15% better performance. With Counter-Strike: Global Offensive with OpenGL was a 14.5% boost, CS:GO with Vulkan was 12.9% faster, and Civilization VI with OpenGL was 11% faster while Strange Brigade was unchanged. No other game numbers were provided.

But as this is about changing the threshold for how aggressively the Intel graphics hardware switches power states, the proposed patches leave it up to user-space to adjust the thresholds as they wish. Google engineers are interested in hooking this into Feral's GameMode so that the values could be automatically tuned when launching games and then returning to their former state when done gaming, in order to maximize battery life / power efficiency. The only downside with these current patches are that they work only for non-GuC based platforms... So the latest Alder/Raptor Lake notebooks as well as Intel DG2/Alchemist discrete graphics currently aren't able to make use of this tuning option.

An anonymous reader quotes a report from ZDNet, written by Steven Vaughan-Nichols: The latest Linux kernel is out with a slew of new features -- and, for once, this release has been nice and easy. [...] Speaking of Rust, everyone's favorite memory-safe language, the new kernel comes with user-mode Linux support for Rust code. Miguel Ojeda, the Linux kernel developer, who's led the efforts to bring Rust to Linux, said the additions mean we're, "getting closer to a point where the first Rust modules can be upstreamed."

Other features in the Linux 6.3 kernel include support and enablement for upcoming and yet-to-be-released Intel and AMD CPUs and graphics hardware. While these updates will primarily benefit future hardware, several changes in this release directly impact today's users' day-to-day experience. The kernel now supports AMD's automatic Indirect Branch Restricted Speculation (IBRS) feature for Spectre mitigation, providing a less performance-intensive alternative to the retpoline speculative execution.

Linux 6.3 also includes new power management drivers for ARM and RISC-V architectures. RISC-V has gained support for accelerated string functions via the Zbb bit manipulation extension, while ARM received support for scalable matrix extension 2 instructions. For filesystems, Linux 6.3 brings AES-SHA2-based encryption support for NFS, optimizations for EXT4 direct I/O performance, low-latency decompression for EROFS, and a faster Brtfs file-system driver. Bottom line: many file operations will be a bit more secure and faster.

For gamers, the new kernel provides a native Steam Deck controller interface in HID. It also includes compatibility for the Logitech G923 Xbox edition racing wheel and improvements to the 8BitDo Pro 2 wired game controllers. Who says you can't game on Linux? Single-board computers, such as BannaPi R3, BPI-M2 Pro, and Orange Pi R1 Plus, also benefit from updated drivers in this release. There's also support for more Wi-Fi adapters and chipsets. These include: Realtek RTL8188EU Wi-Fi adapter support; Qualcomm Wi-Fi 7 wireless chipset support; and Ethernet support for NVIDIA BlueField 3 DPU. For users dealing with complex networks that have both old-school and modern networks, the new kernel can also handle multi-path TCP handling mixed flows with IPv4 and IPv6. Linux 6.3 is available from kernel.org. You can learn how to compile the Linux kernel yourself here.

According to Phoronix citing multiple local North Carolina news outlets, Red Hat is cutting "hundreds of jobs" in an initial round of layoffs announced today. From the report: According to WRAL, Red Hat CEO Matt Hicks is said to have told employees in an email "we will not reduce roles directly selling to customers or building our products," which is hopefully good news for their many upstream Linux developers they employ that ultimately build Red Hat Enterprise Linux and associated software products. Red Hat will begin notifying affected employees today in some countries while the process will continue through the end of the quarter. IBM, which acquired Red Hat in 2019, has already slashed some five thousand positions so far in 2023.

9to5Linux reports: KDE-focused and Arch Linux-inspired independent distribution KaOS Linux celebrates today 10 years of existence with a new stable ISO release that brings some of the latest GNU/Linux technologies and a preview of the upcoming KDE Plasma 6 desktop environment.

Yes, you're reading it right, KaOS is one of the very first GNU/Linux distributions to offer you a live ISO image with a pre-release version of the KDE Plasma 6 desktop, which, of course, is compiled against the latest Qt 6 open-source application framework...

Since this is a special ISO release, the devs also added an option to play music during the installation process.
"KaOS uses the Systemd-provided Systemd-boot for UEFI installs," according to the release notes.

The Linux Foundation, the nonprofit tech consortium that manages various open source efforts, today announced the launch of the TLA+ Foundation to promote the adoption and development of the TLA+ programming language. AWS, Oracle and Microsoft are among the inaugural members. From a report: What is the TLA+ programming language, you ask? It's a formal "spec" language developed by computer scientist and mathematician Leslie Lamport. Best known for his seminal work in distributed systems, Lamport -- now a scientist at Microsoft Research -- created TLA+ to design, model, document and verify software programs -- particularly those of the concurrent and distributed variety.

To give a few examples, ElasticSearch, the organization behind the search engine of the same name, used TLA+ to verify the correctness of their distributed systems algorithms. Elsewhere, Thales, the electrical systems manufacturing firm, used TLA+ to model and develop fault-tolerant modules for its industrial control platform. "TLA+ is unique in that it's intended for specifying a system, rather than for implementing software," a Linux Foundation spokesperson told TechCrunch via email. "Based on mathematical concepts, notably set theory and temporal logic, TLA+ allows for the expression of a system's desired correctness properties in a formal and rigorous manner."
