prisoninmate shares a report from 9to5Linux: Canonical released today Ubuntu 24.04 LTS (Noble Numbat) as the latest version of its popular Linux-based operating system featuring some of the latest GNU/Linux technologies and Open Source software. Powered by Linux kernel 6.8, Ubuntu 24.04 LTS features the latest GNOME 46 desktop environment, an all-new graphical firmware update tool called Firmware Updater, Netplan 1.0 for state-of-the-art network management, updated Ubuntu font, support for the deb822 format for software sources, increased vm.max_map_count for better gaming, and Mozilla Thunderbird as a Snap by default.

It also comes with an updated Flutter-based graphical desktop installer that's now capable of updating itself and features a bunch of changes like support for accessibility features, guided (unencrypted) ZFS installations, a new option to import auto-install configurations for templated custom provisioning, as well as new default installation options, such as Default selection (previously Minimal) and Extended selection (previously Normal)."

An anonymous reader quotes a report from Ars Technica: There's a new Linux distro on the scene today, and it's a bit specialized. Its development was led by the automotive electronics supplier Elektrobit, and it's the first open source OS that complies with the automotive industry's functional safety requirements. [...] With Elektrobit's EB corbos Linux for Safety Applications (that sure is a long name), there's an open source Linux distro that finally fits the bill, having just been given the thumbs up by the German organization TUV Nord. (It also complies with the IEC 61508 standard for safety applications.) "The beauty of our concept is that you don't even need to safety-qualify Linux itself," said Moritz Neukirchner, a senior director at Elektrobit overseeing SDVs. Instead, an external safety monitor runs in a hypervisor, intercepting and validating kernel actions.

"When you look at how safety is typically being done, look at communication -- you don't safety-certify the communication specs or Ethernet stack, but you do a checker library on top, and you have a hardware anchor for checking down below, and you insure it end to end but take everything in between out of the certification path. And we have now created a concept that allows us to do exactly that for an operating system," Neukirchner told me. "So in the end, since we take Linux out of the certification path and make it usable in a safety-related context, we don't have any problems in keeping up to speed with the developer community," he explained. "Because if you start it off and say, 'Well, we're going to do Linux as a one-shot for safety,' you're going to have the next five patches and you're off [schedule] again, especially with the security regulation that's now getting toward effect now, starting in July with the UNECE R155 that requires continuous cybersecurity management vulnerability scanning for all software that ends up in the vehicle."

"In the end, we see roughly 4,000 kernel security patches within eight years for Linux. And this is the kind of challenge that you're being put up to if you want to participate in that speed of innovation of an open source community as rich as that of Linux and now want to combine this with safety-related applications," Neukirchner said. Elektrobit developed EB corbos Linux for Safety Applications together with Canonical, and together they will share the maintenance of keeping it compliant with safety requirements over time.

prisoninmate writes: Fedora Linux 40 distribution has been officially released -- powered by the latest Linux 6.8 kernel series, and featuring the GNOME 46 and KDE Plasma 6 desktop environments, reports 9to5Linux:

"Powered by the latest and greatest Linux 6.8 kernel series, the Fedora Linux 40 release ships with the GNOME 46 desktop environment for the flagship Fedora Workstation edition and the KDE Plasma 6 desktop environment for the Fedora KDE Spin, which defaults to the Wayland session as the X11 session was completely removed."

"Fedora Linux 40 also includes some interesting package management changes, such as dropping Delta RPMs and disabling support in the default configuration of DNF / DNF5. It also changes the DNF behavior to no longer download filelists by default. However, this release doesn't ship with the long-awaited DNF5 package manager. For AMD GPUs, Fedora Linux 40 ships with AMD ROCm 6.0 as the latest release of AMD's software optimized for AI and HPC workload performance, which enables support for the newest flagship AMD Instinct MI300A and MI300X datacenter GPUs."

SiliconANGLE reports that to help organizations detect vulnerabilities earlier, Red Hat has "announced updates to its Trusted Software Supply Chain that enable organizations to shift security 'left' in the software supply chain." Red Hat announced Trusted Software Supply Chain in May 2023, pitching it as a way to address the rising threat of software supply chain attacks. The service secures software pipelines by verifying software origins, automating security processes and providing a secure catalog of verified open-source software packages. [Thursday's updates] are aimed at advancing the ability for customers to embed security into the software development life cycle, thereby increasing software integrity earlier in the supply chain while also adhering to industry regulations and compliance standards.

They start with a new tool called Red Hat Trust Artifact Signer. Based on the open-source Sigstore project [founded at Red Hat and now part of the Open Source Security Foundation], Trust Artifact Signer allows developers to sign and verify software artifacts cryptographically without managing centralized keys, to enhance trust in the software supply chain. The second new release, Red Hat Trusted Profile Analyzer, provides a central source for security documentation such as Software Bill of Materials and Vulnerability Exploitability Exchange. The tool simplifies vulnerability management by enabling proactive identification and minimization of security threats.

The final new release, Red Hat Trusted Application Pipeline, combines the capabilities of the Trusted Profile Analyzer and Trusted Artifact Signer with Red Hat's internal developer platform to provide integrated security-focused development templates. The feature aims to standardize and accelerate the adoption of secure development practices within organizations.
Specifically, Red Hat's announcement says organizations can use their new Trust Application Pipeline feature "to verify pipeline compliance and provide traceability and auditability in the CI/CD process with an automated chain of trust that validates artifact signatures, and offers provenance and attestations."

Michael Larabel reports via Phoronix: While Fedora 41 in late 2024 is aiming to have more reproducible package builds, openSUSE Factory has already achieved a significant milestone in bit-by-bit reproducible builds. Since last month openSUSE Factory has been producing bit-by-bit reproducible builds sans the likes of embedded signatures. OpenSUSE Tumbleweed packages for that rolling-release distribution are being verified for bit-by-bit reproducible builds. SUSE/openSUSE is still verifying all packages are yielding reproducible builds but so far it's looking like 95% or more of packages are working out. You can learn more via the openSUSE blog.

BrianFagioli shares a report from BetaNews: Mozilla has announced Firefox Nightly for ARM64. This release will cater to the growing demand for support on ARM64 platforms, commonly referred to as AArch64. Feedback from the community has led Mozilla to expand the availability of Firefox Nightly. Users can now access the browser as both .tar archives and .deb packages, depending on their preference and requirements for installation.

For those who favor traditional methods, the .tar.bz2 binaries are accessible through Mozilla's downloads page by selecting the option for Firefox Nightly for Linux ARM64/AArch64. Meanwhile, users looking to utilize updates and installation through Mozilla's APT repository can follow specific instructions to install the firefox-nightly package.

Linus Torvalds, discussing the AI hype, in a conversation with Dirk Hohndel, Verizon's Head of the Open Source Program Office: Torvalds snarked, "It's hilarious to watch. Maybe I'll be replaced by an AI model!" As for Hohndel, he thinks most AI today is "autocorrect on steroids." Torvalds summed up his attitude as, "Let's wait 10 years and see where it actually goes before we make all these crazy announcements."

That's not to say the two men don't think AI will be helpful in the future. Indeed, Torvalds noted one good side effect already: "NVIDIA has gotten better at talking to Linux kernel developers and working with Linux memory management," because of its need for Linux to run AI's large language models (LLMs) efficiently.

Torvalds is also "looking forward to the tools actually to find bugs. We have a lot of tools, and we use them religiously, but making the tools smarter is not a bad thing. Using smarter tools is just the next inevitable step. We have tools that do kernel rewriting, with very complicated scripts, and pattern recognition. AI can be a huge help here because some of these tools are very hard to use because you have to specify things at a low enough level." Just be careful, Torvalds warns of "AI BS." Hohndel quickly quipped, "He meant beautiful science. You know, "Beautiful science in, beautiful science out."

Michael Larabel reports via Phoronix: Within yesterday's Linux 6.9-rc4 release is an interesting little nugget by Linus Torvalds to battle Kconfig parsers that can't correctly handle tabs but rather just assume spaces for whitespace for this kernel configuration format. Due to a patch having been queued last week to replace a tab with a space character in the kernel tracing Kconfig file, Linus Torvalds decided to take matters into his own hand for Kconfig parsers that can't deal with tabs... Torvalds authored a patch to intentionally add some tabs of his own into Kconfig for throwing off any out-of-tree/third-party parsers that can't correctly handle them. Torvalds added these intentional hidden tabs to the common Kconfig file for handling page sizes for the kernel. Thus sure to cause dramatic and noticeable breakage for any parsers not having tabs correctly.

Ubuntu 24.10 [expected this October] and Debian GNU/Linux 13 "Trixie" [expected June-July 2025] "will feature a refined APT command-line interface," reports 9to5Linux: APT developer and Canonical engineer Julian Andres Klode took to LinkedIn to present the revamped APT interface powered by the upcoming APT 3.0 package manager that looks to give users a more concise and well-laid-out command-line output when updating, installing, or removing packages via the terminal emulator.

The new APT 3.0 UI brings a columnar display that will make it easier for users to quickly scan for a package name, support for colors (red for removals and green for other changes), which makes it easier to quickly distinguish commands at a glance, and smoother install progress bars using Unicode blocks.

In addition, the new APT 3.0 command-line interface will be less verbose and offer more padding to make it easier to separate sections and extract the relevant information for you.

An anonymous reader shared this report from BleepingComputer: Researchers have demonstrated the "first native Spectre v2 exploit" for a new speculative execution side-channel flaw that impacts Linux systems running on many modern Intel processors. Spectre V2 is a new variant of the original Spectre attack discovered by a team of researchers at the VUSec group from VU Amsterdam. The researchers also released a tool that uses symbolic execution to identify exploitable code segments within the Linux kernel to help with mitigation.

The new finding underscores the challenges in balancing performance optimization with security, which makes addressing fundamental CPU flaws complicated even six years after the discovery of the original Spectre....

As the CERT Coordination Center (CERT/CC) disclosed yesterday, the new flaw, tracked as CVE-2024-2201, allows unauthenticated attackers to read arbitrary memory data by leveraging speculative execution, bypassing present security mechanisms designed to isolate privilege levels. "An unauthenticated attacker can exploit this vulnerability to leak privileged memory from the CPU by speculatively jumping to a chosen gadget," reads the CERT/CC announcement. "Current research shows that existing mitigation techniques of disabling privileged eBPF and enabling (Fine)IBT are insufficient in stopping BHI exploitation against the kernel/hypervisor."
"For a complete list of impacted Intel processors to the various speculative execution side-channel flaws, check this page updated by the vendor."

According to StatCounter, Linux on the desktop has continued to rise and remain above 4%. GamingOnLinux reports: First hitting over 4% in February, their March data is now in showing not just staying above 4% but rising a little once again showing the trend is clear that Linux use is rising. Slow and steady wins the race as they say. [Last March, Linux on the desktop was at 2.85%.]

Technically, ChromeOS is also Linux, and while people like to debate that if you do include Linux and ChromeOS together it would actually be 6.32%. A number that is getting steadily harder for developers of all kinds to ignore. It terms of overall percentage, it's still relatively small but when you think about how many people that actually is, it's a lot. Since StatCounter gets its data from web traffic, it's unlikely the rise is due to the Steam Deck and its SteamOS. "I doubt all that many browse the web regularly on Deck," writes GameOnLinux's Liam Dawe. "However, indirectly? Possible, I've seen lots and lots of posts about people enjoying Linux thanks to the Desktop Mode on the Steam Deck."

The Document Foundation: Following a successful pilot project, the northern German federal state of Schleswig-Holstein has decided to move from Microsoft Windows and Microsoft Office to Linux and LibreOffice (and other free and open source software) on the 30,000 PCs used in the local government. As reported on the homepage of the Minister-President: "Independent, sustainable, secure: Schleswig-Holstein will be a digital pioneer region and the first German state to introduce a digitally sovereign IT workplace in its state administration. With a cabinet decision to introduce the open-source software LibreOffice as the standard office solution across the board, the government has given the go-ahead for the first step towards complete digital sovereignty in the state, with further steps to follow."

Bill Toulas reports via BleepingComputer: Firmware security firm Binarly has released a free online scanner to detect Linux executables impacted by the XZ Utils supply chain attack, tracked as CVE-2024-3094. CVE-2024-3094 is a supply chain compromise in XZ Utils, a set of data compression tools and libraries used in many major Linux distributions. Late last month, Microsoft engineer Andres Freud discovered the backdoor in the latest version of the XZ Utils package while investigating unusually slow SSH logins on Debian Sid, a rolling release of the Linux distribution.

The backdoor was introduced by a pseudonymous contributor to XZ version 5.6.0, which remained present in 5.6.1. However, only a few Linux distributions and versions following a "bleeding edge" upgrading approach were impacted, with most using an earlier, safe library version. Following the discovery of the backdoor, a detection and remediation effort was started, with CISA proposing downgrading the XZ Utils 5.4.6 Stable and hunting for and reporting any malicious activity.

Binarly says the approach taken so far in the threat mitigation efforts relies on simple checks such as byte string matching, file hash blocklisting, and YARA rules, which could lead to false positives. This approach can trigger significant alert fatigue and doesn't help detect similar backdoors on other projects. To address this problem, Binarly developed a dedicated scanner that would work for the particular library and any file carrying the same backdoor. [...] Binarly's scanner increases detection as it scans for various supply chain points beyond just the XZ Utils project, and the results are of much higher confidence. Binarly has made a free API available to accomodate bulk scans, too.

"What a time we live in," writes Phoronix, "where Microsoft not only continues contributing significantly to the Linux kernel but doing so to further flesh out the design of the Linux kernel's Rust programming language support..." Microsoft engineer Wedson Almeida Filho has sent out the latest patches working on Allocation APIs for the Rust Linux kernel code and also in leveraging those proposed APIs [as] a means of allowing in-place module initialization for Rust kernel modules. Wedson Almeida Filho has been a longtime Rust for Linux contributor going back to his Google engineering days and at Microsoft the past two years has shown no signs of slowing down on the Rust for Linux activities...

The Rust for Linux kernel effort remains a very vibrant effort with a wide variety of organizations contributing, even Microsoft engineers.

BrianFagioli shares a report from BetaNews: In a recent security announcement, Red Hat's Information Risk and Security and Product Security teams have identified a critical vulnerability in the latest versions of the 'xz' compression tools and libraries. The affected versions, 5.6.0 and 5.6.1, contain malicious code that could potentially allow unauthorized access to systems. Fedora Linux 40 users and those using Fedora Rawhide, the development distribution for future Fedora builds, are at risk.

The vulnerability, designated CVE-2024-3094, impacts users who have updated to the compromised versions of the xz libraries. Red Hat urges all Fedora Rawhide users to immediately cease using the distribution for both work and personal activities until the issue is resolved. Plans are underway to revert Fedora Rawhide to the safer xz-5.4.x version, after which it will be safe to redeploy Fedora Rawhide instances. Although Fedora Linux 40 builds have not been confirmed to be compromised, Red Hat advises users to downgrade to a 5.4 build as a precautionary measure. An update reverting xz to 5.4.x has been released and is being distributed to Fedora Linux 40 users through the normal update system. Users can expedite the update by following instructions provided by Red Hat. Further reader submissions: xz/liblzma Backdoored, Facilitating ssh Compromise;

An anonymous reader shares a report: Mutterings of alarm are emerging from the cloisters of Red Hat after the world's largest management consultancy was hired to help the IBM subsidiary focus engineers on their highest-value work. Red Hat confirmed the partnership with McKinsey & Company to The Reg, sharing this extract from an email from CTO Chris Wright to the Global Engineering Team:

"Hey everyone -- as I mentioned during the recent Q1 All Hands, my goal is to have Global Engineering recognized as the world's greatest open-source software engineering organization. This team is already doing amazing work, and we have several initiatives in progress to help us achieve the goal I've set. One of those is a partnership with McKinsey. The objective of this project is to help us understand and incorporate learnings on working models, development practices, and tooling from across the software industry.

"We've heard your feedback in person, during All Hands, and through RHAS [the annual Red Hat Associate Survey]. This project will help us to identify and remove mundane tasks that drain your energy so that you can focus on the most engaging and highest value work â" to make your job better. The work with McKinsey is one piece of the overall plan to help us become the world's greatest open-source software engineering organization"

Michael Larabel reports via Phoronix: Given the recent change by Redis to adopt dual source-available licensing for all their releases moving forward (Redis Source Available License v2 and Server Side Public License v1), the Linux Foundation announced today their fork of Redis. The Linux Foundation went public today with their intent to fork Valkey as an open-source alternative to the Redis in-memory store. Due to the Redis licensing changes, Valkey is forking from Redis 7.2.4 and will maintain a BSD 3-clause license. Google, AWS, Oracle, and others are helping form this new Valkey project.

The Linux Foundation press release shares: "To continue improving on this important technology and allow for unfettered distribution of the project, the community created Valkey, an open source high performance key-value store. Valkey supports the Linux, macOS, OpenBSD, NetBSD, and FreeBSD platforms. In addition, the community will continue working on its existing roadmap including new features such as a more reliable slot migration, dramatic scalability and stability improvements to the clustering system, multi-threaded performance improvements, triggers, new commands, vector search support, and more. Industry participants, including Amazon Web Services (AWS), Google Cloud, Oracle, Ericsson, and Snap Inc. are supporting Valkey. They are focused on making contributions that support the long-term health and viability of the project so that everyone can benefit from it."

BrianFagioli shares a report from BetaNews: Canonical, the company behind the popular Ubuntu operating system, has announced a significant extension to the support lifecycle of its long-term support (LTS) releases. The new paid Legacy Support add-on for Ubuntu Pro subscribers will now provide security maintenance and support for an impressive 12 years, extending the previous 10-year commitment. This enhancement is available starting with Ubuntu 14.04 LTS and will benefit both enterprises and individual users who rely on the stability and security of Ubuntu for their critical systems. By default, Ubuntu LTS releases receive five years of standard security maintenance. However, with Ubuntu Pro, this is expanded to 10 years for both the main and universe repositories, offering access to a broader range of secure open-source software.

The Legacy Support add-on further extends this period by an additional two years, ensuring that organizations can maintain their systems with the latest security patches and support services without the immediate need to upgrade to a newer OS version. This is particularly beneficial for large, established production systems where transitioning to a new OS can be a complex and risky endeavor due to the potential need to update the entire software stack. The extended support includes continuous vulnerability management for critical, high, and medium Common Vulnerabilities and Exposures (CVEs) across all software packages shipped with Ubuntu. Canonical's security team actively backports crucial fixes to all supported Ubuntu LTS releases, providing peace of mind to users and enterprises. In addition to security maintenance, the Legacy Support add-on also offers phone and ticket support, enhancing Canonical's commitment to assisting customers with troubleshooting, break fixes, bug fixes, and guidance.

"Until recently, Linux kernel developers have been the ones keeping long-term support (LTS) versions of the Linux kernel patched and up to date," writes ZDNet.

"Then, because it was too much work with too little support, the Linux kernel developers decided to no longer support the older kernels." Greg Kroah-Hartman, the Linux kernel maintainer for the stable branch, announced that the Linux 4.14.336 release was the last maintenance update to the six-year-old LTS Linux 4.14 kernel series. It was the last of the line for 4.14. Or was it?

Kroah-Hartman had stated, "All users of the 4.14 kernel series must upgrade." Maybe not. OpenELA, a trade association of the Linux distributors CIQ (the company backing Rocky Linux), Oracle, and SUSE, is now offering — via its kernel-lts — a new lease on life for 4.14.

This renewed version, tagged with the following format — x.y.z-openela — is already out as v4.14.339-openela. The OpenELA acknowledges the large debt they owe to Kroah-Hartman and Sasha Levin of the Linux Kernel Stable project but underlines that their project is not affiliated with them or any of the other upstream stable maintainers. That said, the OpenELA team will automatically pull most LTS-maintained stable tree patches from the upstream stable branches. When there are cases where patches can't be applied cleanly, OpenELA kernel-lts maintainers will deal with these issues. In addition, a digest of non-applied patches will accompany each release of its LTS kernel, in mbox format.
"The OpenELA kernel-lts project is the first forum for enterprise Linux distribution vendors to pool our resources," an Oracle Linux SVP tells ZDNet, "and collaborate on those older kernels after upstream support for those kernels has ended." And the CEO of CIQ adds that after community support has ended, "We believe that open collaboration is the best way to maintain foundational enterprise infrastructure.

"Through OpenELA, vendors, users, and the open source community at large can work together to provide the longevity that professional IT organizations require for enterprise Linux."

An anonymous reader shares a report: Linus Torvalds has released version 6.8 of the Linux Kernel. "So it took a bit longer for the commit counts to come down this release than I tend to prefer," Torvalds wrote on the Linx kernel mailing list on Sunday, "but a lot of that seemed to be about various selftest updates (networking in particular) rather than any actual real sign of problems."

"And the last two weeks have been pretty quiet, so I feel there's no real reason to delay 6.8." So he delivered it, ending his own speculation that this cut of the kernel might need an eighth release candidate. Torvalds found time to note what he described as "a bit of random git numerology" as when work ended on this version of the kernel the git repository used to track it contained 9.996 million objects."

"This is the last mainline kernel to have less than ten million git objects," Torvalds wrote. "Of course, there is absolutely nothing special about it apart from a nice round number. Git doesn't care," he added. Fair enough -- especially as noted that other trees, such as linux-next, have well and truly passed ten million objects.
