OpenStreetMap Migrates To Debian 12 For Enhanced Performance
by Peter Reutemann 04 Dec '24

04 Dec '24

'OpenStreetMap (OSM), the collaborative project to create a free and open map of the world, has migrated its servers to Debian 12 (Bookworm) after 18 years on Ubuntu. This transition brings with it a number of benefits, including improved speed and closer ties with the Debian community. Why the Switch? The decision to migrate was driven by a number of factors, with performance being a key consideration. OSM's infrastructure relies heavily on physical hardware, and the team encountered significant I/O performance issues with certain kernel versions on systems using NVMe storage. Debian 12 offered a solution by allowing the installation of backported kernels, effectively resolving these performance bottlenecks. Another motivating factor was the desire to align more closely with the maintainers of the software packages that OSM relies on. Debian boasts a strong reputation for package maintenance, and many Debian maintainers are deeply invested in the software they support, ensuring prompt attention to critical bugs. A Smooth Transition The migration process was facilitated by OSM's infrastructure management practices. Their server setup is largely code-driven, and rigorous testing is performed using tools like Test Kitchen and Inspec. By adding Debian as a test target platform, the team was able to identify and address any compatibility issues early on. The required code changes were relatively minor, primarily involving adjustments to package names and configuration filenames. The transition involved the following key steps: - Frontend Server Migration: OSM successfully migrated its frontend servers to Debian 12, resulting in a Ruby version upgrade from 3.0 to 3.1. This upgrade allowed for a corresponding upgrade to the Ruby on Rails framework used for the www.openstreetmap.org website. - Networking Management Shift: OSM transitioned from using netplan, the default network management tool in Ubuntu, to systemd-networkd, Debian's preferred tool. This change streamlined network management across both Ubuntu and Debian systems, ensuring consistency. - Custom Package Management: OSM adopted aptly to manage their own Debian package repository. This shift from Ubuntu's Personal Package Archives (PPA) was driven by the need to manage pre-release or custom patches of OSM software. A Shared Community The move to Debian also reflects the strong overlap between the OSM and Debian communities. Many OSM contributors are also active within the Debian ecosystem, fostering a shared understanding and collaborative spirit.' -- source: https://ostechnix.com/openstreetmap-migrates-to-debian-12-for-enhanced-perf… Cheers, Peter

Code found online exploits LogoFAIL to install Bootkitty Linux backdoor
by Peter Reutemann 02 Dec '24

02 Dec '24

'Researchers have discovered malicious code circulating in the wild that hijacks the earliest stage boot process of Linux devices by exploiting a year-old firmware vulnerability when it remains unpatched on affected models. The critical vulnerability is one of a constellation of exploitable flaws discovered last year and given the name LogoFAIL. These exploits are able to override an industry-standard defense known as Secure Boot and execute malicious firmware early in the boot process. Until now, there were no public indications that LogoFAIL exploits were circulating in the wild. The discovery of code downloaded from an Internet-connected web server changes all that. While there are no indications the public exploit is actively being used, it is reliable and polished enough to be production-ready and could pose a threat in the real world in the coming weeks or months. Both the LogoFAIL vulnerabilities and the exploit found on-line were discovered by Binarly, a firm that helps customers identify and secure vulnerable firmware.' -- source: https://arstechnica.com/security/2024/11/code-found-online-exploits-logofai… Cheers, Peter

GIMP 3.0 - a Milestone For Open-Source Image Editing
by Peter Reutemann 30 Nov '24

30 Nov '24

'The long-awaited release of the GNU Image Manipulation Program (GIMP) 3.0 is on the way, marking the first major update since version 2.10 was released in April 2018. It now features a GTK 3 user interface and GIMP 3.0 introduces significant changes to the core platform and plugins. This release also brings performance and usability improvements, as well as more compatibility with Wayland and complex input sources. GIMP 3.0 is the first release to use GTK 3, a more modern foundation than the GTK 2 base of prior releases. GTK 4 has been available for a few years now, and is on the project's radar, but the plan was always to finish the GTK 3 work first. Moving to GTK 3 brings initial Wayland compatibility and HiDPI scaling. In addition, this allows for GIMP users to take advantage of multi-touch input, bringing pinch-to-zoom gestures to the program, and offering a better experience when working with complex peripherals, such as advanced drawing tablets. These features were not previously possible due to the limitations of GTK 2. A secondary result of the transition to GTK 3 is a refreshed user interface (UI), now with support for CSS themes included. In this release, four themes are available by default, including light, dark, and gray themes, along with a high-contrast theme for users with visual impairments. Additionally, this release has transitioned to using GTK's header bar component, typically used to combine an application's toolbar and title bar into one unit. To maintain familiarity with previous releases, however, GIMP 3.0 still supports the traditional menu interface.' -- source: https://tech.slashdot.org/story/24/11/29/134239/ Cheers, Peter

Both KDE and GNOME To Offer Official Distros
by Peter Reutemann 30 Nov '24

30 Nov '24

'KDE and GNOME have decided that because they're not big and complicated enough already, they might work better if they have their own custom distributions underneath. What's the worst that could happen? A talk from this year's KDE conference, Akademy 2024, looks like it's going to become real. The talk, by KDE developer Harald Sitter, was entitled An Operating System of Our Own, and the idea sounds simple enough: Sitter proposed an official KDE Linux distribution. Now the proposal is gathering steam and a plan is coming together for an official KDE Linux -- codenamed "Project Banana."' -- source: https://tech.slashdot.org/story/24/11/29/2055220 Cheers, Peter

file browser
by Peter Reutemann 26 Nov '24

26 Nov '24

Hi there Today, I decided to finally switch my default file browser to krusader: https://krusader.org/ For a number of years, I've been using double-commander: https://doublecmd.sourceforge.io/ Mostly, I was quite happy with double-commander, as it had my preferred two-panel approach for managing files (I frequently copy files between various directories around for testing models etc). The two-panel approach was something I came to appreciate back in the DOS days when using the Norton Commander. With Double-commander I could also have an arbitrary number of tabs within a panel. The function buttons at the bottom (rename/copy/view/terminal/etc) were also quite handy when using the mouse. And, very importantly, Double-commander is available for Windows as well. However, remote access via sftp was quite slow (viewing and copying files) and that's when I had to fall back on caja, as it had a much higher throughput. Compared to caja, krusader is much faster when listing remote files. Waiting around for caja to refresh a few thousand files was taking way too long (sometimes up to 30 seconds). That's what gave me the final push to make the switch (on my development machine). Double-commander will still be my go-to tool for Windows machines. Anyway, what is your preferred file browser? Cheers, Peter

g: An Elegant Alternative for the ls Command in Linux
by Peter Reutemann 25 Nov '24

25 Nov '24

Hi everyone Just came across this post: '“g” is a free and open-source cross-platform alternative to the ls command, offering more advanced features than any other alternative, such as what “exa” can provide. The developer named this tool “g” because it’s written in Go, and “g” is simply easy to remember. It offers various ways to customize output, multiple ways to layout the output, integrated support for Git, advanced sorting mechanisms, fuzzy path matching, and hyperlink support.' -- source: https://linuxtldr.com/g-alternative-of-the-ls-command/ Looks like an interesting alternative. :-) Cheers, Peter

Red Hat is Becoming an Official Microsoft 'Windows Subsystem for Linux' Distro
by Peter Reutemann 24 Nov '24

24 Nov '24

'You can use any Linux distribution inside of the Windows Subsystem for Linux" Microsoft recently reminded Windows users, "even if it is not available in the Microsoft Store, by importing it with a tar file." But being an official distro "makes it easier for Windows Subsystem for Linux users to install and discover it with actions like wsl --list --online and wsl --install," Microsoft pointed out this week. And "We're excited to announce that Red Hat will soon be delivering a Red Hat Enterprise Linux WSL distro image in the coming months..." Thank you to the Red Hat team as their feedback has been invaluable as we built out this new architecture, and we're looking forwards to the release...! Ron Pacheco, senior director, Red Hat Enterprise Linux Ecosystem, Red Hat says: "Developers have their preferred platforms for developing applications for multiple operating systems, and WSL is an important platform for many of them. Red Hat is committed to driving greater choice and flexibility for developers, which is why we're working closely with the Microsoft team to bring Red Hat Enterprise Linux, the largest commercially available open source Linux distribution, to all WSL users." Read Pacheco's own blog post here. But in addition Microsoft is also releasing "a new way to make WSL distros," they announced this week, "with a new architecture that backs how WSL distros are packaged and installed." Up until now, you could make a WSL distro by either creating an appx package and distributing it via the Microsoft Store, or by importing a .tar file with wsl -import. We wanted to improve this by making it possible to create a WSL distro without needing to write Windows code, and for users to more easily install their distros from a file or network share which is common in enterprise scenarios... With the tar based architecture, you can start with the same .tar file (which can be an exported Linux container!) and just edit it to add details to make it a WSL distro... These options will describe key distro attributes, like the name of the distro, its icon in Windows, and its out of box experience (OOBE) which is what happens when you run WSL for the first time. You'll notice that the oobe_command option points to a file which is a Linux executable, meaning you can set up your full experience just in Linux if you wish.

Ubuntu Linux Impacted By Decade-Old 'needrestart' Flaw That Gives Root
by Peter Reutemann 21 Nov '24

21 Nov '24

'Five local privilege escalation (LPE) vulnerabilities in the Linux utility "needrestart" -- widely used on Ubuntu to manage service updates -- allow attackers with local access to escalate privileges to root. The flaws were discovered by Qualys in needrestart version 0.8, and fixed in version 3.8. BleepingComputer reports: Complete information about the flaws was made available in a separate text file, but a summary can be found below: - CVE-2024-48990: Needrestart executes the Python interpreter with a PYTHONPATH environment variable extracted from running processes. If a local attacker controls this variable, they can execute arbitrary code as root during Python initialization by planting a malicious shared library. - CVE-2024-48992: The Ruby interpreter used by needrestart is vulnerable when processing an attacker-controlled RUBYLIB environment variable. This allows local attackers to execute arbitrary Ruby code as root by injecting malicious libraries into the process. - CVE-2024-48991: A race condition in needrestart allows a local attacker to replace the Python interpreter binary being validated with a malicious executable. By timing the replacement carefully, they can trick needrestart into running their code as root. - CVE-2024-10224: Perl's ScanDeps module, used by needrestart, improperly handles filenames provided by the attacker. An attacker can craft filenames resembling shell commands (e.g., command|) to execute arbitrary commands as root when the file is opened. - CVE-2024-11003: Needrestart's reliance on Perl's ScanDeps module exposes it to vulnerabilities in ScanDeps itself, where insecure use of eval() functions can lead to arbitrary code execution when processing attacker-controlled input. The report notes that attackers would need to have local access to the operation system through malware or a compromised account in order to exploit these flaws. "Apart from upgrading to version 3.8 or later, which includes patches for all the identified vulnerabilities, it is recommended to modify the needrestart.conf file to disable the interpreter scanning feature, which prevents the vulnerabilities from being exploited," adds BleepingComputer.' -- source: https://it.slashdot.org/story/24/11/21/0057206 Cheers, Peter

Linux Kernel 6.12 Has Been Released
by Peter Reutemann 18 Nov '24

18 Nov '24

'Slashdot unixbhaskar writes: Linus has released a fresh Linux kernel for public consumption. Please give it a try and report any glitches to the maintainers for improvement. Also, please do not forget to express your appreciation to those tireless folks who did all the hard work for you. The blog OMG Ubuntu calls it "one of the most biggest kernel releases for a while," joking that it's a "really real-time kernel." The headline feature in Linux 6.12 is mainline support for PREEMPT_RT. This patch set dramatically improves the performance of real-time applications by making kernel processes pre-emptible — effectively enabled proper real-time computing... Meanwhile, Linus Torvalds himself contributes a new method for user-space address masking designed to claw back some of the performance lost due to Spectre-v1 mitigations. You might have heard that kernel devs have been working to add QR error codes to Linux's kernel panic BSOD screen (as a waterfall of error text is often cut off and not easily copied for ad-hoc debugging). Well, Linux 6.12 adds support for those during Direct Rendering Manager panics... A slew of new RISC-V CPU ISA extensions are supported in Linux 6.12; hybrid CPU scaling in the Intel P-State driver lands ahead of upcoming Intel Core Ultra 2000 chips; and AMD P-State driver improves AMD Boost and AMD Preferred Core features. More coverage from the blog 9to5Linux highlights a new scheduler called sched_ext, Clang support (including LTO) for nolibc, support for NVIDIA's virtual command queue implementation for SMMUv3, and "an updated cpuidle tool that now displays the residency value of cpuidle states for a clearer and more detailed view of idle state information when using cpuidle-info." Linux kernel 6.12 also introduces SWIG bindings for libcpupower to make it easier for developers to write scripts that use and extend the functionality of libcpupower, support for translating normalized error addresses reported by an AMD memory controller into system physical addresses using a UEFI mechanism called platform runtime mechanism (PRM), as well as simplified loading of microcode patches on AMD Zen and newer CPUs by using the family, model, and stepping encoded in the patch revision number... Moreover, Linux 6.12 adds support for running as a protected guest on Android as well as perf and support for a bunch of new interconnect PMUs. It also adds the final conversions to the new Intel VFM CPU model matching macros, rewrites the PCM buffer allocation handling and locking optimizations, and improves the USB audio driver...

mailing list alternatives
by Peter Reutemann 18 Nov '24

18 Nov '24

Hi everyone Here is a list of all the potential options for having the WLUG mailing list continue in some form after the University of Waikato will shut down their mailman instance next month: 1. TechnologyWise would support us and host it at Catalyst (Wellington) Type: unspecified (since general hosting, could be mailman?) Comment: TW ran the BOP LUG that way 2. Linux Australia (https://lists.linux.org.au/mailman/listinfo) Type: mailman (open-source) Comment: not yet contacted whether they'd be open to it 3. Don Gould Type: unspecified (has FLOSS platform, so could be mailman) 4. NZOSS Type: discourse (open-source, at community.iridescent.nz) Comment: unlikely to migrate archives 5. Outlook Groups option Type: MS Outlook (proprietary) Comment: just email distribution, probably no archives In terms of WLUG list archives... I've experimented with hypermail (https://github.com/hypermail-project/hypermail) and was able to turn the 53MB mbox file containing all our posts from the last 25 years into 183MB of HTML. That way, we can at least ensure that the old content doesn't get lost completely. I also talked to Daniel Lawson, who's hosting the old WLUG website and wiki. Though he is not keen on managing mail (bit of a nightmare nowadays according to him), he'd be willing to host the HTML version of the archives. Please reply to this post with your preferred option(s) by Saturday night (e.g., "1" or "1 3 4"). On Sunday, I will then create a final tally (hopefully). Thanks again for your suggestions!

New systemd update will bring Windows’ infamous Blue Screen of Death to Linux
by Peter Reutemann 18 Nov '24

18 Nov '24

'Windows' infamous "Blue Screen of Death" is a bit of a punchline. People have made a hobby of spotting them out in the wild, and in some circles, they remain a byword for the supposed flakiness and instability of PCs. To this day, networked PCs in macOS are represented by beige CRT monitors displaying a BSOD. But the BSOD is supposed to be a diagnostic tool, an informational screen that technicians can use to begin homing in on the problem that caused the crash in the first place; that old Windows' BSOD error codes were often so broad and vague as to be useless doesn't make the idea a bad one. Today, version 255 of the Linux systemd project honors that original intent by adding a systemd-bsod component that generates a full-screen display of some error messages when a Linux system crashes. The systemd-bsod component is currently listed as "experimental" and "subject to change." But the functionality is simple: any logged error message that reaches the LOG_EMERG level will be displayed full-screen to allow people to take a photo or write it down. Phoronix reports that, as with BSODs in modern Windows, the Linux version will also generate a QR code to make it easier to look up information on your phone.' -- source: https://arstechnica.com/gadgets/2023/12/linux-distros-are-about-to-get-a-ki… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GIMP 3.0 Release Candidate Is Now Available for Public Testing
by Peter Reutemann 07 Nov '24

07 Nov '24

'The development team behind the popular GIMP open-source image editing software announced today the general availability of the Release Candidate (RC) milestone of the highly anticipated GIMP 3.0 release. Featuring a much-refined interface, GIMP 3.0 introduces massive improvements to color management, a stable public API to allow porting of plug-ins and scripts from the GIMP 2.10 series, support for loading layers from TIFF files saved in the Autodesk Sketchbook format, and support for 64 bits per pixel images for the BMP format. GIMP 3.0 also promises improvements to non-destructive editing by introducing an optional “Merge Filters” checkbox at the bottom of NDE filters that merges down the filter immediately after it’s committed, along with non-destructive filters on layer groups and the implementation of storing version of filters in GIMP’s XCF project files. “This will allow us to update filters in the future without impacting how older project files look when they’re opened. Additional work will be needed in GEGL to fully implement this feature, but that can be done after 3.0 without impacting existing project files,” said the devs. Among other noteworthy changes, the updated UI of GIMP 3.0 allows the use of the mouse scroll wheel to flip through different dockable dialogue tabs, GEGL and babl components have been updated with new features and many improvements, such as Inner Glow, Bevel, and GEGL Styles filters, and some plugins saw small enhancements. On top of all that, GIMP 3.0 also comes with a new logo, a new splash screen, improvements to the legacy icon theme to look great on HiDPI screens, and the ability to export images with different settings while leaving the original image unchanged.' -- source: https://9to5linux.com/gimp-3-0-release-candidate-is-now-available-for-publi… Cheers, Peter

Linux Mint and Framework Laptops Join Forces
by Peter Reutemann 07 Nov '24

07 Nov '24

'Linux Mint and Framework Laptops Join Forces The October 2024 edition of Linux Mint’s Monthly News brings exciting updates, including a significant announcement about collaboration with Framework Laptops, having potential to advance Mint’s compatibility with hardware designed with flexibility, repairability, and sustainability in mind. For those unfamiliar, unlike most traditional laptops, which are often difficult or impossible to repair or upgrade, Framework laptops are built to be user-friendly, making it easy to replace or upgrade components. This modular approach extends the laptop’s lifespan and promotes sustainability by reducing e-waste. According to Clement Lefebvre, the driving force behind the Linux Mint project, the team recently received Framework’s Laptop 13, and initial impressions are promising. But more importantly, this partnership could open new avenues for Linux Mint, allowing the development team to work with advanced components and technologies featured in Framework’s offerings that haven’t previously been on the project’s radar. Of course, this also means that if compatibility progresses smoothly, Linux Mint could confidently recommend Framework Laptops to its community without hesitation. As Lefebvre noted, the full review of the Laptop 13 will be available in next month’s update, but early sentiments are already positive. Apart from that, the Linux Mint team is currently working on integrating Night Light support into the Cinnamon desktop environment, thus aiming to reduce eye strain for its users. Furthermore, efforts are ongoing to migrate key Cinnamon dialogs to Clutter, enhancing functionality and design. This includes familiar dialogs like the one used to unlock keyrings or confirm display settings.' -- source: https://linuxiac.com/linux-mint-and-framework-laptops-join-forces/ Cheers, Peter

How to Use Syntax Highlighting in Nano Editor
by Peter Reutemann 07 Nov '24

07 Nov '24

I thought, the following tutorial on how to enable syntax highlighting in nano would be quite a useful one for people commonly using that editor: 'Nano is a simple and user-friendly command-line text editor for Linux, which is often used for basic text editing tasks, such as creating and editing configuration files, scripts, or simple documents. However, many users don’t know that Nano supports syntax highlighting, which can make editing code files easier by coloring different parts of the text (like keywords, variables, and comments) for better visibility.

KDE’s New Distro: Btrfs-Based, Immutable Linux OS, with Flatpak and Snap
by Peter Reutemann 04 Nov '24

04 Nov '24

'Surprises never end. The KDE project is about to take a bold step by introducing its own Linux distribution. Here’s what it’s all about. Introduced at Akademy 2024, KDE Linux (codenamed “Project Banana”) is a brand-new, still-in-development initiative by the KDE devs to bring a seamless, user-friendly experience that merges KDE software’s reliability and rich interface with cutting-edge Linux technologies. Immediately, we want to clarify that this isn’t a rebranded version of the well-known KDE Neon developed by the KDE community. KDE Linux is an entirely new project with a completely different technical approach under the hood and ambitious goals for both developers and end users. The distro is designed to be a bulletproof, highly user-friendly operating system that showcases the best of KDE technology—a system that KDE can confidently recommend to casual users and hardware manufacturers. With an eye on simplicity, the OS will use Btrfs for its file system and introduce an image-based (immutable) approach, allowing users to easily switch between different OS versions, ensuring a secure, flexible experience without the stress of traditional system management. KDE Linux will feature rolling OS updates based on snapshot releases and employs systemd-boot with custom theming. All mutable data, such as user home directories and cache locations, is encrypted for enhanced security. Moreover, the architecture also includes an image-based A/B update mechanism with rollback capabilities and a recovery partition for added resilience. Users can benefit from an automatic backup system using Btrfs snapshots, which includes a user-friendly GUI similar to Apple’s Time Machine. Using Arch as a base, KDE Linux aims to attract a broad audience, including KDE developers, enthusiasts, and hardware vendors. It will include applications from Flatpak (and possibly Snap), helping to keep the core system and applications separate for greater stability.' -- source: https://linuxiac.com/kde-announced-its-kde-linux-distro/ Cheers, Peter

Local Privilege Escalation Vulnerability Affecting X.Org Server For 18 Years
by Peter Reutemann 30 Oct '24

30 Oct '24

'Phoronix's Michael Larabel reports: CVE-2024-9632 was made public today as the latest security vulnerability affecting the X.Org Server. The CVE-2024-9632 security issue has been present in the codebase now for 18 years and can lead to local privilege escalation. Introduced in the X.Org Server 1.1.1 release back in 2006, CVE-2024-9632 affects the X.Org Server as well as XWayland too. By providing a modified bitmap to the X.Org Server, a heap-based buffer overflow privilege escalation can occur. This security issue is within _XkbSetCompatMap() and stems from not updating the heap size properly and can lead to local privilege escalation if the server is run as root or as a remote code execution with X11 over SSH.' -- source: https://it.slashdot.org/story/24/10/29/2029233 Cheers, Peter

Debian's "secret" sauce
by Peter Reutemann 29 Oct '24

29 Oct '24

'While Debian's "sauce" is not actually all that secret, it is not particularly well-known either, Samuel Henrique said at the start of his DebConf24 talk. There is a lot of software-engineering effort that has been put in place by the distribution in order to create and maintain its releases, but ""loads of people are not aware"" of it. That may be due to the fact that all of that is not really documented anywhere in a central location that he can just point someone to. Recognizing that is what led him to give the talk; hopefully it will be a ""first step toward"" helping solve the problem. Henrique said that he is a Brazilian and has been a Debian Developer since 2018. He mostly works in the security tools packaging team, but also maintains some packages outside of that team, including curl and rsync. In addition, he mentors Debian newcomers, mostly on packaging tasks. He works on the Amazon Linux security team. He noted that his web site contains links to the slides from the talk; a WebM video is also available. [Update: A YouTube video with subtitles in English and Portuguese is also available.]' -- source: https://lwn.net/Articles/990177/ Cheers, Peter

Discovering the Joys of E-Books with Calibre
by Ben Cottrell 29 Oct '24

29 Oct '24

I was lucky to come across a collection of Cybersecurity E-Books on Humble Bundle, spending around 40 NZD to receive 21 books. After paying for and downloading the books, the PDF’s weren’t named tidily, so I decided to use Calibre to organize my collection. Calibre categorized the books under author subdirectories and named them by title nicely. It couldn’t open the PDF’s itself, it does a good job cataloguing. Do you have any favourite tools or scripts for managing E-Books? Please let me know 😊 Cheers, Ben

Raspberry Pi OS’s yearslong switch from X Window to Wayland is now official
by Peter Reutemann 29 Oct '24

29 Oct '24

'There have been times when it seemed like X Window System would be with us forever, even though it's more than 40 years old, and the last true version was issued in 2012. But with great effort, some organizations and operating systems have moved on. Raspberry Pi has now joined the forward momentum, with its latest release of Raspberry Pi OS swapping in Wayland—and it's hoping the change is hardly noticeable. You might want to wait a moment before upgrading, though. Simon Long wrote on Raspberry Pi's blog that the organization started thinking about switching to Wayland about 10 years ago, though it was "nowhere near ready to use" back then. Over the last few years, the Pi team has done some things to prep a real switch: - Used mutter as an X window manager in 2021's Bullseye release because it could also be used as a Wayland compositor - Switched from mutter to wayfire in 2023's Bookworm release and made Wayland the default for Raspberry Pi 4 and 5 - Switched one last time to labwc, which better fit Raspberry Pi's graphics hardware than wayfire Because labwc is built on wlroots, a modular system that allows for building a Wayland compositor without whole-cloth reinvention, it was easier to adapt to Raspberry Pi's needs. After efforts throughout 2024, the team is ready to call it the year of Wayland on Raspberry Pi desktops. "After much optimisation for our hardware, we have reached the point where labwc desktops run just as fast as X on older Raspberry Pi models," Long wrote. "Today, we make the switch with our latest desktop image: Raspberry Pi Desktop now runs Wayland by default across all models."' -- source: https://arstechnica.com/gadgets/2024/10/raspberry-pi-oss-years-long-switch-… Cheers, Peter

AI Scams In The Knitting And Crochet World
by Lawrence D'Oliveiro 26 Oct '24

26 Oct '24

I suppose if you spend much time in online software support forums, you’ve come across the newbie who asked an AI to generate some code for them, and then asks for help to figure out why it didn’t work. But did you know that knitting and crochet patterns are like computer code, too? And that people are using AI to generate those? And that the same problems of quality control are afflicting them? Unlike computer software, where once you track down the bug, you can usually fix just that one line and run the code again, a flaw in a knitting or crochet pattern can require you to throw away hours of work, unpicking your way back to the point where the flaw was introduced, before you can fix it and continue from that point again. And food recipes are becoming infested with AI rubbish as well. Here you might be tricked into following some interesting-looking recipe, perhaps quite complicated, only to end up with an inedible, revolting mess, and money wasted on all the ingredients, as well as time wasted doing the work. <https://www.zdnet.com/article/ai-scams-have-infiltrated-the-knitting-and-cr…>

5 Stand-Out LibreOffice Features That Make It My Go-To Office Suite
by Lawrence D'Oliveiro 17 Oct '24

17 Oct '24

From <https://www.zdnet.com/home-and-office/work-life/5-stand-out-libreoffice-fea…>: Customizable GUI: For example, when writing a novel, I want the sidebar always readily available because I need quick access to formatting options. If I'm working on a more traditional document, I might go with the tabbed UI. For spreadsheets, I want the simplest UI that I can use, such as the contextual single UI. LibreOffice makes this possible, with the ability to switch between a standard toolbar, tabbed, single toolbar, sidebar, tabbed compact, groupedbar compact, and contextual single. You can even make changes to different tools, which allows you to have one UI for Writer, one for Calc, and one for Presents. Customizable styles: What I like about this feature is that it allows me to get very granular with the styles, even to the point where I can define what style comes next, how drop caps are handled, transparency, borders, indents & spacing, text flow, font, position, highlights, much more. No AI: (what more needs to be said?) Microsoft Office compatibility: For a while, I was writing everything in Google Docs; that is, until one of my editors complained of incompatibility issues (even when exporting to the .docx format with Docs). Once I switched from Google Docs to LibreOffice (for my fiction writing), those issues all went away. Document export: LibreOffice document export allows you to export your Writer documents to XHTML, PDF, EPUB, MediaWiki, Writer Indexing Export XML, JPEG, Writer Layout XML, PNG, and WEBP. You can also save as ODF, ODF Template, Flat XML, Unified Office Format, Word 2010-365, Word 2007, Word 2007 Template, Word 2003 XML, Rich Text, Word 97-2003, and other types. If there's a format you need, more than likely LibreOffice can export it. ... I can also ask what version of MS Office a collaborator is using and make sure to export it to the most compatible version. Because, you know, even Microsoft Office cannot manage 100% compatibility with Microsoft Office ...

Resetting USB Controllers After Error
by Lawrence D'Oliveiro 16 Oct '24

16 Oct '24

I was doing my semi-regular backup of some core essential files onto USB sticks today, and hit an error writing to one of the sticks (I replaced it with a spare). However, the error left the USB on my main machine in a strange state: it still thought the bad USB stick was present on the bus, even though it had been removed. And also my USB audio interface stopped working (though thankfully not my mouse or keyboard). I found the “usbreset” utility program. Trying to reset the nonexistent device of course returned an error that it did not exist. It listed three USB hubs, and I thought if I reset the one that the stick had been connected to, that might work. I was able to reset two of the hubs, but it hung on the third one (very likely the source of the problem). And the problem remained unfixed. I thought I was going to have to reboot my machine. Then, after hunting around online, I found this little shell script <https://unix.stackexchange.com/questions/704341/how-to-reset-usb-controllers>, which finds all your USB controller interfaces and tells them to “unbind”, and then “rebind”, all devices attached to each. And that worked! I have my 5.1 USB audio working again! Of course, I can’t guarantee it’ll work for you, if you hit a similar problem, but I figure, how could it hurt to try? ;)

If I Buy Something, Do I Own It?
by Lawrence D'Oliveiro 12 Oct '24

12 Oct '24

For some reason, it was never considered deceptive for shops to advertise themselves as “selling” CDs and tapes and videocassettes and DVDs and video games; if you bothered to ask, you discovered that what you were buying was a “licence” to use the product, not ownership of the product as such. Well, that’s changing, at least in some places. The US state of California has now decreed that not mentioning this distinction between “licence” and “ownership” constitutes false advertising, so vendors had better make it clear <https://arstechnica.com/gaming/2024/10/steam-now-reminds-you-that-it-really…>. In case customers get upset at discovering something they should have realized before, the article ends with the reassuring words: So long as Steam lasts forever, however, this new language should not be that alarming.

Thousands of Linux systems infected by stealthy malware since 2021
by Peter Reutemann 04 Oct '24

04 Oct '24

'Thousands of machines running Linux have been infected by a malware strain that’s notable for its stealth, the number of misconfigurations it can exploit, and the breadth of malicious activities it can perform, researchers reported Thursday. The malware has been circulating since at least 2021. It gets installed by exploiting more than 20,000 common misconfigurations, a capability that may make millions of machines connected to the Internet potential targets, researchers from Aqua Security said. It can also exploit CVE-2023-33426, a vulnerability with a severity rating of 10 out of 10 that was patched last year in Apache RocketMQ, a messaging and streaming platform that’s found on many Linux machines. Perfctl storm The researchers are calling the malware Perfctl, the name of a malicious component that surreptitiously mines cryptocurrency. The unknown developers of the malware gave the process a name that combines the perf Linux monitoring tool and ctl, an abbreviation commonly used with command line tools. A signature characteristic of Perfctl is its use of process and file names that are identical or similar to those commonly found in Linux environments. The naming convention is one of the many ways the malware attempts to escape notice of infected users. Perfctl further cloaks itself using a host of other tricks. One is that it installs many of its components as rootkits, a special class of malware that hides its presence from the operating system and administrative tools. Other stealth mechanisms include: - Stopping activities that are easy to detect when a new user logs in - Using a Unix socket over TOR for external communications - Deleting its installation binary after execution and running as a background service thereafter - Manipulating the Linux process pcap_loop through a technique known as hooking to prevent admin tools from recording the malicious traffic - Suppressing mesg errors to avoid any visible warnings during execution. The malware is designed to ensure persistence, meaning the ability to remain on the infected machine after reboots or attempts to delete core components. Two such techniques are (1) modifying the ~/.profile script, which sets up the environment during user login so the malware loads ahead of legitimate workloads expected to run on the server and (2) copying itself from memory to multiple disk locations. The hooking of pcap_loop can also provide persistence by allowing malicious activities to continue even after primary payloads are detected and removed. Besides running using the machine resources to mine cryptocurrency, Perfctl also turns the machine into a profit-making proxy that paying customers use to relay their Internet traffic. Aqua Security researchers have also observed the malware serving as a backdoor to install other families of malware.' -- source: https://arstechnica.com/security/2024/10/persistent-stealthy-linux-malware-… Cheers, Peter

Mozilla's massive lapse in judgement causes clash with uBlock Origin developer
by Peter Reutemann 02 Oct '24

02 Oct '24

'Software developers who publish their products on third-party stores face all kinds of problems sometimes. From rejected apps or extensions to removed products or unjustified claims about them. Raymond "gorhill" Hill, maker of the world's most popular content blocker uBlock Origin received two emails from Mozilla recently about his Firefox add-on uBlock Origin Lite. Good to know: uBlock Origin Lite is a Manifest V3-compatible version of the content blocker. It is less powerful, but since Google is disabling Manifest V2 support in Chrome, it is what will remain from uBlock Origin for Chromium-based browsers. Mozilla says that it has reviewed the extension and found violations. The following claims were made: - The extension is not asking for consent for data collecting. - The extension contains "minified, concatenated or otherwise machine-generated code". - There is no privacy policy. As a consequence, Mozilla disabled the extension on the Firefox Add-ons Store. Hill refuted all three claims that Mozilla made on the GitHub repository stating that the extension is not collecting any data, that there is no minified code in uBlock Origin Lite, and that there is a privacy policy. He admitted further that he does not "have the time or motivation to spend time on this nonsense" and won't react to the allegations made or appeal the decision.' -- source: https://www.ghacks.net/2024/10/01/mozillas-massive-lapse-in-judgement-cause… Cheers, Peter

I'm using Windows at the moment: what's keeping me back
by Ben Cottrell 01 Oct '24

01 Oct '24

Hi, I'm using Windows 11 on my Lenovo ThinkBook 16p Gen 2, with an NVIDIA GeForce RTX 3060, and an AMD Ryzen 5600H (with integrated Radeon graphics). In the past I've distro hopped, and here were my experiences. I've stuck with Windows because NVIDIA has still not fully committed to supporting the standards needed for Wayland. OpenSUSE Tumbleweed: The first distro that properly worked with UEFI secure booting, in terms of enrolling keys. NVIDIA's drivers would not be loaded by the kernel unless the keys were enrolled. Ubuntu: Good default GTK theme. Good beginner distro. Installing NVIDIA drivers is a little easier than OpenSUSE. NixOS: Cutting edge, and allowed me to run certain applications to run with GPU acceleration. Easy to rollback system wide changes, but I couldn't really grasp their config language. I'm not sure if the issue is down to an insufficient allocation of staff by NVIDIA, or if there's a conflict of interest with Microsoft. Cheers, Ben

Critical Unauthenticated RCE Flaw Impacts All GNU/Linux Systems
by Peter Reutemann 27 Sep '24

27 Sep '24

'"Looks like there's a storm brewing, and it's not good news," writes ancient Slashdot reader jd. "Whether or not the bugs are classically security defects or not, this is extremely bad PR for the Linux and Open Source community. It's not clear from the article whether this affects other Open Source projects, such as FreeBSD." From a report: A critical unauthenticated Remote Code Execution (RCE) vulnerability has been discovered, impacting all GNU/Linux systems. As per agreements with developers, the flaw, which has existed for over a decade, will be fully disclosed in less than two weeks. Despite the severity of the issue, no Common Vulnerabilities and Exposures (CVE) identifiers have been assigned yet, although experts suggest there should be at least three to six. Leading Linux distributors such as Canonical and RedHat have confirmed the flaw's severity, rating it 9.9 out of 10. This indicates the potential for catastrophic damage if exploited. However, despite this acknowledgment, no working fix is still available. Developers remain embroiled in debates over whether some aspects of the vulnerability impact security.' -- source: https://it.slashdot.org/story/24/09/25/2150210 Cheers, Peter

Tor Project Merges With Tails
by Peter Reutemann 27 Sep '24

27 Sep '24

'The Tor Project: Today the Tor Project, a global non-profit developing tools for online privacy and anonymity, and Tails, a portable operating system that uses Tor to protect users from digital surveillance, have joined forces and merged operations. Incorporating Tails into the Tor Project's structure allows for easier collaboration, better sustainability, reduced overhead, and expanded training and outreach programs to counter a larger number of digital threats. In short, coming together will strengthen both organizations' ability to protect people worldwide from surveillance and censorship. Countering the threat of global mass surveillance and censorship to a free Internet, Tor and Tails provide essential tools to help people around the world stay safe online. By joining forces, these two privacy advocates will pool their resources to focus on what matters most: ensuring that activists, journalists, other at-risk and everyday users will have access to improved digital security tools. In late 2023, Tails approached the Tor Project with the idea of merging operations. Tails had outgrown its existing structure. Rather than expanding Tails's operational capacity on their own and putting more stress on Tails workers, merging with the Tor Project, with its larger and established operational framework, offered a solution. By joining forces, the Tails team can now focus on their core mission of maintaining and improving Tails OS, exploring more and complementary use cases while benefiting from the larger organizational structure of The Tor Project. This solution is a natural outcome of the Tor Project and Tails' shared history of collaboration and solidarity. 15 years ago, Tails' first release was announced on a Tor mailing list, Tor and Tails developers have been collaborating closely since 2015, and more recently Tails has been a sub-grantee of Tor. For Tails, it felt obvious that if they were to approach a bigger organization with the possibility of merging, it would be the Tor Project.' -- source: https://yro.slashdot.org/story/24/09/26/1431201 Cheers, Peter

NIST proposes barring some of the most nonsensical password rules
by Peter Reutemann 26 Sep '24

26 Sep '24

'The National Institute of Standards and Technology (NIST), the federal body that sets technology standards for governmental agencies, standards organizations, and private companies, has proposed barring some of the most vexing and nonsensical password requirements. Chief among them: mandatory resets, required or restricted use of certain characters, and the use of security questions. Choosing strong passwords and storing them safely is one of the most challenging parts of a good cybersecurity regimen. More challenging still is complying with password rules imposed by employers, federal agencies, and providers of online services. Frequently, the rules—ostensibly to enhance security hygiene—actually undermine it. And yet, the nameless rulemakers impose the requirements anyway. [...] 1. Verifiers and CSPs SHALL require passwords to be a minimum of eight characters in length and SHOULD require passwords to be a minimum of 15 characters in length. 2. Verifiers and CSPs SHOULD permit a maximum password length of at least 64 characters. 3. Verifiers and CSPs SHOULD accept all printing ASCII [RFC20] characters and the space character in passwords. 4. Verifiers and CSPs SHOULD accept Unicode [ISO/ISC 10646] characters in passwords. Each Unicode code point SHALL be counted as a single character when evaluating password length. 5. Verifiers and CSPs SHALL NOT impose other composition rules (e.g., requiring mixtures of different character types) for passwords. 6. Verifiers and CSPs SHALL NOT require users to change passwords periodically. However, verifiers SHALL force a change if there is evidence of compromise of the authenticator. 7. Verifiers and CSPs SHALL NOT permit the subscriber to store a hint that is accessible to an unauthenticated claimant. 8. Verifiers and CSPs SHALL NOT prompt subscribers to use knowledge-based authentication (KBA) (e.g., “What was the name of your first pet?”) or security questions when choosing passwords. 9. Verifiers SHALL verify the entire submitted password (i.e., not truncate it).' -- source: https://arstechnica.com/security/2024/09/nist-proposes-barring-some-of-the-… Cheers, Peter

Kubuntu Focus Ir14 Gen 2 review: Using Linux instead of messing with it
by Peter Reutemann 25 Sep '24

25 Sep '24

'There are lots of laptops—maybe all of them—on which you can run a Linux desktop. There are a few vendors that offer laptops with extensive Linux compatibility. And then there are a select few that specialize in Linux laptops, support them, and even customize them. Kubuntu Focus is one of the select few. It sent me one of its laptops to test the Ir14 Gen 2, which runs, of course, Kubuntu, the KDE desktop variant of Ubuntu. The “Focus” in the company name comes from what it is hoping to provide: a device on which you can just do your work without worrying about what’s happening deeper in your system. Go ahead and sudo apt update, says the Focus team; we’ve got you. I used the Ir14 Gen 2 for Ars Technica work and my personal needs for at least two weeks. Setting the system up with Focus’ guided wizard, installing apps from its store, and refusing to touch any of the deeper system files, I achieved something pretty remarkable: no unexpected behaviors on a Linux laptop. Had anything gone wrong, I could reasonably lean back on the system’s rollbacks, which I used a couple of times with no problem. Is this what it could be like? Does using Linux on the desktop not have to involve compiling from source, searching for that one relevant forum comment related to a problem, wondering where the fault lies along the chain from kernel to desktop to repository to me? Maybe. Can you surrender a bit of your upgrade and tinkering curiosity in exchange for knowing that things will work when they get to you? It might be trickier than you think. A Kubuntu Focus Ir14 Gen 2 laptop includes these things: - A laptop made by Carbon Systems, which supplies a lot of fleet and enterprise systems, and happens to make them relatively upgrade and repair-friendly - A stock Kubuntu 24.04 LTS system with a Plasma desktop, with Focus’ integrations built in - A few software tools from Focus, including power profiles and rollback The Focus is not meant to let you do whatever you want but to keep doing what you do. Researchers, developers, and jet propulsion labs are some of Focus’ customers. Focus tests everything that will arrive on official update channels to the device. When kernel updates appear in the upstream, Focus makes sure everything on the device works with it, while also contributing back to Ubuntu, Kubuntu, KDE, and the kernel itself. You don’t get interim releases. You don’t get staff in the forums helping you with running Arch or Fedora. There’s no custom desktop environment or windowing system (“We felt building a separate distribution and ecosystem is the last thing anyone needed,” the company writes). Focus chose reliability for daily-driver devices running Linux. It can, in other words, save you from yourself, if you’re a lot like me. Besides testing, Focus also makes a bunch of tweaks to the system before shipping: some keyboard shortcuts, screen scaling and console font alterations, automatic power profiles on plug and unplug, and the like. Focus has also written up almost every corner of your system you want help on; you can check it out on its site.' -- source: https://arstechnica.com/gadgets/2024/09/kubuntu-focus-ir14-gen-2-review-usi… Cheers, Peter

Linux boots in 4.76 days on the Intel 4004
by Peter Reutemann 24 Sep '24

24 Sep '24

'Hardware hacker Dmitry Grinberg recently achieved what might sound impossible: booting Linux on the Intel 4004, the world's first commercial microprocessor. With just 2,300 transistors and an original clock speed of 740 kHz, the 1971 CPU is incredibly primitive by modern standards. And it's slow—it takes about 4.76 days for the Linux kernel to boot. Initially designed for a Japanese calculator called the Busicom 141-PF, the 4-bit 4004 found limited use in commercial products of the 1970s before being superseded by more powerful Intel chips, such as the 8008 and 8080 that powered early personal computers—and then the 8086 and 8088 that launched the IBM PC era. If you're skeptical that this feat is possible with a raw 4004, you're right: The 4004 itself is far too limited to run Linux directly. Instead, Grinberg created a solution that is equally impressive: an emulator that runs on the 4004 and emulates a MIPS R3000 processor—the architecture used in the DECstation 2100 workstation that Linux was originally ported to.

Zen Browser: a New Firefox-based Alternative to Chromium Browsers
by Peter Reutemann 24 Sep '24

24 Sep '24

'First released on July 11th, the Firefox-based Zen browser is "taking a different approach to the user interface," according to the blog It's FOSS. The Register says the project "reminds us strongly of Arc, a radical Chromium-based web browser... to modernize the standard web browser UI by revising some fundamental assumptions." [Arc] removes the URL bar from front and center, gets rid of the simple flat list of tabs, and so on. Zen is trying to do some similar things, but in a slightly more moderate way — and it's doing it on the basis of Mozilla's Firefox codebase... Instead of the tired old horizontal tab bar you'll see in both Firefox and Chrome, Zen implements its own tab bar... By default, this tab bar is narrow and just shows page icons — but there are some extra controls at the bottom of the sidebar, one of which expands the sidebar to show page titles too. For us, it worked better than Vivaldi's fancier sidebar. The article concludes it's "a new effort to modernize web browsing by bringing tiling, workspaces, and so on — and it's blissfully free of Google code." One Reddit comment swooned over Zen's "extraordinary" implementation of a distraction-free "Compact Mode" (hiding things like the sidebar and top bar). And It's Foss described it as a "tranquil," browser, "written using CSS, C++, JavaScript, and a few other programming languages, with a community of over 30 people contributing to it." The layout of the interface felt quite clean to me; there were handy buttons on the top to control the webpage, manage extensions, and a menu with additional options... The split-view functionality allows you to open up two different tabs on the same screen, allowing for easy multitasking when working across different webpages... I split two tabs, but in my testing, I could split over 10+ tabs... If you have a larger monitor, then you are in for a treat... The Zen Sidebar feature... can run web apps alongside any open tabs. This can be helpful in situations where you need to quickly access a service like a note-taking app, Wikipedia, Telegram, and others. On the customization side of things, you will find that Zen Browser supports everything that Firefox does, be it the settings, adding new extensions/themes/plugins, etc. The Register points out it's easy to give it a try. "Being based on Firefox means that as well as running existing extensions, it can connect to Mozilla's Sync service and pick up not just your bookmarks, but also your tabs from other instances." And beyond all that, "There's just something satisfying about switching browsers every now and again..." argues the tech site Pocket-Lint: Zen Browser's vertical tabs layout is superb and feels much better than anything available in standard Firefox. [Firefox recently offered vertical tabs and a new sidebar experience in Nightly/Firefox Labs 131.] The tab bar can be set to automatically hide and show up whenever you hover near it, and it also contains quick access buttons to bookmarks, settings, and browsing history. The tab bar also contains a profile switcher... One of the greatest parts of the Zen Browser is the community that has popped up around it. At its heart, Zen Browser is a community-driven project... Zen Browser themes are aesthetic and functional tweaks to the UI. While there aren't a ton available right now, the ones that are show a lot of promise for the browser's future... I've personally gotten great use out of the Super URL Bar theme, which makes your URL bar expand and become the focus of your screen while typing in it... There's a lot you can do to make Zen Browser feel nearly exactly like what you want it to feel like. The "Business Standard calls it "an open-source alternative to Chromium-based browsers," adding "Where Zen truly shines is it offers a range of customisation, tab management, and workspace management..." Their theme store offers a range of options, including modifications to the bookmark toolbar, a floating URL bar, private mode theming, and removal of browser padding. In addition to these, users can also choose from custom colour schemes and built-in theming options... The Sidebar is another neat feature which allows you to open tabs in a smaller, smartphone-sized window. You can view websites in mobile layout by using this panel. It's "focused on being always at the latest version of Firefox," according to its official site, noting that Firefox is known for its security features. But then, "We also have additional security features like https only built into Zen Browser to help keep you safe online." And it also promises automated Releases "to ensure security." It's FOSS adds that you can get Zen Browser for Linux, Windows, and macOS from its official website (adding "They also offer it on the Flathub store for further accessibility on Linux.") And its source code is available on GitHub.' -- source: https://news.slashdot.org/story/24/09/23/0353206 Cheers, Peter

As Companies Try 'Open Source Rug Pull', Open Source Foundations Considered Helpful
by Peter Reutemann 22 Sep '24

22 Sep '24

'"In the era of the open source rug pull, the role of open source foundations is more important than ever," argues the co-founder of the developer-focused industry analyst firm RedMonk: The "rug pull" here refers to companies that have used open source as a distribution mechanism, building a community and user base, before changing the license to be restricted, rather than truly open source. "This is capitalism, yo. We've got shareholders to satisfy. It's time to relicense that software, move to a Business Source license." [...] Where open source used to be a sustainable commitment, today too often it feels like a short term tactic. Commercial open source isn't what it used to be. Which means that open source foundations, which provide ongoing governance and intellectual property management for open source projects, are in an interesting position, in some cases becoming more adversarial than they historically have been with vendors.... [T]he Apache Software Foundation (ASF) has done a great job of fostering sustainable, commercial, open source for decades now, most notably in the data infrastructure space — think Hadoop, Spark, Kafka, Flink etc. ["[C]ommercial open source would almost certainly never have achieved critical mass and continued success without foundations in the mix," the article notes later. "The ASF was founded in 1999, and underpinned the adoption of open source middleware in the enterprise..."] One premise behind the Cloud Native Computing Foundation (CNCF) is that user organisations can within reason trust it to stand behind the projects it incubates and manages. While not an explicit commitment, adopters generally, and enterprises specifically, have seen the CNCF imprimatur as one that they can rely on. In the era of the open source rug pull this kind of promise becomes even more important.... Sid Sijbrandij, CEO of GitLab has argued that open source companies should commit to an Open Charter as a mechanism to protect users from open source rug pulls. "Open source software isn't useful if people can't rely on the project remaining open source. Adopting Open Charter offers open source users predictability amidst the growing licensing switch trend." With a CNCF project, though, the need for this kind of charter becomes less important, because the code is by design not single source, but has a diverse set of contributors. Which is to say that open source foundations can make rug pulls a lot less likely than adoption of open source technology built by a single company. Relying on benevolent dictators is generally pretty risky. And recently the benevolent dictators have seemed... less benevolent. In conclusion, "Open Source Foundations Considered Helpful," according to the post's title. It does argue that "Any company is within its rights to relicense its software, but it can certainly be problematic from a community and project health perspective. "Which is exactly why open source foundations are more important than ever."' -- source: https://news.slashdot.org/story/24/09/21/0530234 Cheers, Peter

List Of IPTV Resources
by Lawrence D'Oliveiro 22 Sep '24

22 Sep '24

This user <https://github.com/iptv-org> just popped up in my GitHub feed. One repo <https://github.com/iptv-org/iptv> claims to be a list of links to over 8000 streaming TV channels from nations all over the world, while the other is a list of tools*, providers and other resources. Do be aware it’s a bit of a mixed bag: yes, there are legitimate channels (no encryption so far that I have noticed), but also some dubious-looking links. *Oddly, FFmpeg and youtube-dl aren’t in the list.

Trying Out IPv6
by Lawrence D'Oliveiro 19 Sep '24

19 Sep '24

My new ISP supports IPv6, and I’ve been doing a few tentative tests with it. I actually disabled the DHCPv6 support in my router, and manually configured an address in the ISP-delegated range into my main machine, just for testing. And now I’ve discovered that my other Linux machines have picked up addresses in the delegated range as well, all by themselves! Turns out this is through a mechanism called “SLAAC” (“Stateless Address Autoconfiguration”). My main worry was that, since IPv6 allows direct connections without needing NAT, that internal machines with IPv6 addresses would be directly visible on the Internet. But checking with an external IPv6 ping site seems to show this is not the case: my router is blocking incoming attempts to access nodes on IPv6 addresses by default. The router responds to pings on its own IPv6 address from the public Internet, of course; but other allocated addresses in the range do not respond. Here is a site <https://test-ipv6.com/> I found to test your IPv6 connectivity. It also gives details of the tests it runs, and a handy list of some random places you can access via IPv6.

Real-Time Linux Is Now Mainstream
by Lawrence D'Oliveiro 19 Sep '24

19 Sep '24

The PREEMPT_RT patches (aka “Real-Time Linux”) originated as a set of out-of-tree mods to the Linux kernel about 20 years ago. Bit by bit, over time, various parts of them have been incorporated into the mainline code. Some of these patches have found uses in, shall we say, more mainstream application areas. And beginning with kernel version 6.12, the last of those out-of-tree patches have been merged, and the out-of-tree PREEMPT_RT patchset is no more. This article <https://www.zdnet.com/article/20-years-later-real-time-linux-makes-it-to-th…> by long-time Linux fan Steven J Vaughan-Nichols, gives some background. Including the fact that musicians have been using Linux for audio work for decades, because Linux with the real-time patches was the cheapest way of recording pro-quality audio, much cheaper than buying “real” pro audio gear.

Is Your Windows Licence Legal?
by Lawrence D'Oliveiro 18 Sep '24

18 Sep '24

How do you know your Windows-running PC is running a legitimately-licensed copy of Windows? It seems you can’t: <https://www.zdnet.com/article/is-your-windows-license-legal-should-you-even…>. The article says “You almost certainly have a valid Windows license if you acquired it in ...” and goes on to list the usual ways that users obtain their copies. But note that “almost”: there is nothing you end up with -- no document or artifact or anything else -- that definitively says your copy of Windows is genuine. The final decision always goes back to Microsoft: if they decide not to sue you, then your copy is probably legit.

Chrome Switching To NIST-Approved ML-KEM Quantum Encryption
by Peter Reutemann 18 Sep '24

18 Sep '24

'Google is updating the post-quantum cryptography in Chrome, replacing the experimental Kyber with the fully standardized Module Lattice Key Encapsulation Mechanism (ML-KEM) to enhance protection against quantum computing attacks. BleepingComputer reports: This change comes roughly five months after Google rolled out the post-quantum secure TLS key encapsulation system on Chrome stable for all users, which also caused some problems with TLS exchanges. The move from Kyber to ML-KEM though is not related to those early problems, that got resolved soon after manifesting. Rather, its a strategic choice to abandon an experimental system for a NIST-approved and fully standardized mechanism. ML-KEM was fully endorsed by the U.S. National Institute of Standards and Technology (NIST) in mid-August, with the agency publishing the complete technical specifications of the final version at the time. Google explains that despite the technical changes from Kyber to ML-KEM being minor, the two are essentially incompatible, so a switch had to be made. "The changes to the final version of ML-KEM make it incompatible with the previously deployed version of Kyber," explains Google. "As a result, the codepoint in TLS for hybrid post-quantum key exchange is changing from 0x6399 for Kyber768+X25519, to 0x11EC for ML-KEM768+X25519."

Linus Torvalds Muses About Maintainer Gray Hairs, Next 'King of Linux'
by Peter Reutemann 17 Sep '24

17 Sep '24

'A report from ZDNet, written by Steven Vaughan-Nichols: In a candid keynote chat at the Linux Foundation's Open Source Summit Europe, Linux creator Linus Torvalds shared his thoughts on kernel development, the integration of Rust, and the future of open source. Dirk Hohndel, Verizon's Open Source Program Office head and Torvalds friend, moderated their conversation about the Linux ecosystem. Torvalds emphasized that kernel releases, like the recent 6.11 version, are intentionally not exciting. "For almost 15 years, we've had a very good regular cadence of releases," he explained. With releases every nine weeks, this regularity aims for timeliness and reliability rather than flashy new features. The Linux creator noted that while drivers still make up the bulk of changes, core kernel development continues to evolve. "I'm still surprised that we're doing very core development," Torvalds said, mentioning ongoing work in virtual file systems and memory management. [...] Shifting back to another contentious subject -- maintainer burnout and succession planning -- Hohndel observed that "maintainers are aging. Strangely, some of us have, you know, not quite as much or the right hair color anymore." (Torvalds interjected that "gray is the right color.") Hohndel continued, "So the question that I always ask myself: Is it about time to talk about there being a mini-Linus?" Torvalds turned the question around. True, the Linux maintainers are getting older and people do burn out and go away. "But that's kind of normal. What is not normal is that people actually stay around for decades. That's the unusual thing, and I think that's a good sign." At the same time, Torvalds admitted, it can be intimidating for a younger developer to join the Linux kernel team "when you see all these people who have been around for decades, but at the same time, we have many new developers. Some of those new developers come in, and three years later, they are top maintainers." Hohndel noted that "to be the king of Linux, the main maintainer, you have to have a lot of experience. And the backup right now is Greg KH (Greg Kroah-Hartman, maintainer of the stable Linux kernel), who is about the same age as we are and has even less hair." True, Torvalds responded, "But the thing is, Greg hasn't always been Greg. Before Greg, there's been Andrew {Morton) and Alan (Cox). After Greg, there will be Shannon and Steve. The real issue is you have to have a person or a group of people that the development community can trust, and part of trust is fundamentally about having been around for long enough that people know how you work, but long enough does not mean to be 30 years." Hohndel made one last comment: "What I'm trying to say is, you've been doing this for 33 years. I don't want to be morbid, but I think in 33 years, you may no longer be doing this?" Torvalds, making motions as though he was using a walker, replied, "I would love to still do this conference with you." The report notes the contention around the integration of Rust, highlighted by the recent departure of Rust for Linux maintainer Wedson Filho. Despite resistance from some devs who prefer C and are skeptical of Rust, Torvalds remains optimistic about Rust's future in the kernel. He said: "Rust is a very different thing, and there are a lot of people who are used to the C model. They don't like the differences, but that's OK. In the kernel itself, absolutely nobody understands everything. I don't. I rely heavily on maintainers of various subsystems. I think the same can be true of Rust and C. I think it's one of our strengths in the kernel that we can specialize. Clearly, some people just don't like the notion of Rust and having Rust encroach on their area. But we've only been doing Rust for a couple of years, so it's way too early to say Rust is a failure." Meanwhile, Torvalds confirmed that the long-anticipated real-time Linux (RTLinux) project will finally be integrated into the kernel with the upcoming release of Linux 6.12.' -- source: https://linux.slashdot.org/story/24/09/16/2047217 Cheers, Peter

Linux Kernel 6.11 is Out
by Peter Reutemann 17 Sep '24

17 Sep '24

'Linux creator Linus Torvalds has released version 6.11 of the open-source operating system kernel. The new release, while not considered major by Torvalds, introduces several notable improvements for AMD hardware users and Arch Linux developers. ZDNet: This latest version introduces several enhancements, particularly for AMD hardware users, while offering broader system improvements and new capabilities. These include: RDNA4 Graphics Support: The kernel now includes baseline support for AMD's upcoming RDNA4 graphics architecture. This early integration bodes well for future AMD GPU releases, ensuring Linux users have day-one support. Core Performance Boost: The AMD P-State driver now includes handling for AMD Core Performance Boost. This driver gives AMD Core users more granular control over turbo and boost frequency ranges. Fast Collaborative Processor Performance Control (CPPC) Support: Overclockers who want the most power possible from their computers will be happy with this improvement to the AMD P-State driver. This feature enhances power efficiency on recent Ryzen (Zen 4) mobile processors. This can improve performance by 2-6% without increasing power consumption. AES-GCM Crypto Performance: AMD and Intel CPUs benefit from significantly faster AES-GCM encryption and decryption processing, up to 160% faster than previous versions.' -- source: https://linux.slashdot.org/story/24/09/16/1928224 Cheers, Peter

Neofetch is over, but many screenshot system info tools stand ready
by Peter Reutemann 16 Sep '24

16 Sep '24

'Almost nobody truly needed Neofetch, but the people who did use it? They really liked it. Neofetch, run from a terminal, displayed key system information alongside an ASCII-art image of the operating system or distribution running on that system. You knew most of this data, but if you're taking a screenshot of your system, it looked cool and conveyed a lot of data in a small space. "The overall purpose of Neofetch is to be used in screen-shots of your system," wrote Neofetch's creator, Dylan Araps, on its Github repository. "Neofetch shows the information other people want to see." Neofetch did that, providing cool screenshots and proof-of-life images across nearly 150 OS versions until late April. The last update to the tool was made three years before that, and Araps' Github profile now contains a rather succinct coda: "Have taken up farming." Araps joins "going to a commune in Vermont" and "I now make furniture out of wood" in the pantheon of programmers who do not just leave the field, but flee into another realm entirely.

Haiku (Originally 'OpenBeOS') Releases Long Awaited R1/Beta5
by Peter Reutemann 16 Sep '24

16 Sep '24

'Haiku (the MIT-licensed operating system, inspired by BeOS) has released its fifth beta for Haiku R1. Some new features include improved UI color management, improved dark mode coloring, Tracker improvements, TUN/TAP support for VPN connections, TCP throughput improvements, performance optimizations, UFS2 (BSD's filesystem) read-only support, new FAT filesystem driver, improved hardware support, improved POSIX compliance, improved performance, and more. Slashdot has been covering the fate of the BeOS since 2000 (as well as the short-lived derivative project ZETA — and Haiku). And now "With a history of over two decades and previously known as OpenBeOS, today's Haiku is pushing forward..." writes the site NotebookCheck: Haiku is a spiritual successor to BeOS, with a focus on a clean and user-friendly design paired with low system requirements. The minimum system requirements are still an Intel Pentium II/AMD Athlon CPU or better, at least 384 MB RAM, an 800x600 screen, and at least 3GB storage. It works on both 32-bit and 64-bit x86 PCs, and the 32-bit version can run many unmodified BeOS applications. It might be the best desktop open-source operating system not based on Linux or Unix... It works well in a virtual machine like VirtualBox or UTM. ' -- source: https://news.slashdot.org/story/24/09/14/158240 Anybody ever tried running/using Haiku? Cheers, Peter

'Samba is "a free software re-implementation of the SMB networking protocol," according to Wikipedia. And now the Samba project "has secured significant funding (€688,800.00) from the German Sovereign Tech Fund to advance the project," writes Jeremy Allison — Sam (who is Slashdot reader #8,157 — and also a long standing member of Samba's core team): The investment was successfully applied for by [information security service provider] SerNet. Over the next 18 months, Samba developers from SerNet will tackle 17 key development subprojects aimed at enhancing Samba's security, scalability, and functionality. The Sovereign Tech Fund is a German federal government funding program that supports the development, improvement, and maintenance of open digital infrastructure. Their goal is to sustainably strengthen the open source ecosystem. The project's focus is on areas like SMB3 Transparent Failover, SMB3 UNIX extensions, SMB-Direct, Performance and modern security protocols such as SMB over QUIC. These improvements are designed to ensure that Samba remains a robust and secure solution for organizations that rely on a sovereign IT infrastructure. Development work began as early as September the 1st and is expected to be completed by the end of February 2026 for all sub-projects. All development will be done in the open following the existing Samba development process. First gitlab CI pipelines have already been running and gitlab MRs will appear soon! Back in 2000, Jeremy Allison answered questions from Slashdot readers about Samba. Allison is now a board member at both the GNOME Foundation and the Software Freedom Conservancy, a distinguished engineer at Rocky Linux creator CIQ, and a long-time free software advocate.' -- source: https://news.slashdot.org/story/24/09/14/1726252 Cheers, Peter

Rogue WHOIS server gives researcher superpowers no one should ever have
by Peter Reutemann 12 Sep '24

12 Sep '24

'It’s not every day that a security researcher acquires the ability to generate counterfeit HTTPS certificates, track email activity, and the position to execute code of his choice on thousands of servers—all in a single blow that cost only $20 and a few minutes to land. But that’s exactly what happened recently to Benjamin Harris. Harris, the CEO and founder of security firm watchTowr, did all of this by registering the domain dotmobiregistry.net. The domain was once the official home of the authoritative WHOIS server for .mobi, a top-level domain used to indicate that a website is optimized for mobile devices. At some point—it’s not clear precisely when—this WHOIS server, which acts as the official directory for every domain ending in .mobi, was relocated, from whois.dotmobiregistry.net to whois.nic.mobi. While retreating to his Las Vegas hotel room during last month’s Black Hat security conference in Las Vegas, Harris noticed that the previous dotmobiregistry.net owners had allowed the domain to expire. He then scooped it up and set up his own .mobi WHOIS server there.' -- source: https://arstechnica.com/security/2024/09/rogue-whois-server-gives-researche… Cheers, Peter

Hi everyone Just came across the Floorp browser, which is based on Firefox. Refreshing news, as most new browsers nowadays seem to be Chromium-based... 'Floorp, an amazing free and open-source browser backed by a Japanese company, has gained quite a bit of attention recently for offering data and privacy protection, including high customization options such as Vivaldi in relation to Chrome. The browser's performance was quite fascinating, as it was able to achieve 60% more speed compared to Firefox when tested with Speedometer and JetStream 2 benchmarking tools. If your current browser is Firefox and you love to tweak your browser, then I highly recommend you give it a try. The following is a list of data privacy and customization options offered by Floorp: - An option to enable strong fingerprints, disabling WebGL, and HTTPs for every site is available. - Open the link, image, and media in a new tab and immediately move to it. - Provide a vertical tab on the right side of the browser to quickly open certain sites or browser settings. - Built-in option to change between different user agents. - Offers a preset of 80 keyboard shortcuts for different browser actions. - It comes with Floorp Notes Sync, similar to Vivialdi, to keep your notes. - Integrated with Firefox sync to synchronize your browser bookmarks, cookies, logins, open tabs, etc.' -- source: https://ubuntushell.com/install-floorp/ -- project: https://floorp.app/ Cheers, Peter

Mostly monochrome, but I still found several of them mind-blowing. Not sure if the audio was part of the same AI process, or if the artist (yes, I’d call them an artist) created that separately. Yeah, there are lots of glitches and bugs and hilariously impossible occlusions and the like. But that just adds to the hallucinatory feel. And each one is short, which leaves you wanting more. Wouldn’t you like to spend some time in a world like one of those? Just try to ignore the glitches in the matrix and go with the flow. ;)

'The YubiKey 5, the most widely used hardware token for two-factor authentication based on the FIDO standard, contains a cryptographic flaw that makes the finger-size device vulnerable to cloning when an attacker gains brief physical access to it, researchers said Tuesday. ArsTechnica: The cryptographic flaw, known as a side channel, resides in a small microcontroller that's used in a vast number of other authentication devices, including smartcards used in banking, electronic passports, and the accessing of secure areas. While the researchers have confirmed all YubiKey 5 series models can be cloned, they haven't tested other devices using the microcontroller, which is SLE78 made by Infineon and successor microcontrollers known as the Infineon Optiga Trust M and the Infineon Optiga TPM. The researchers suspect that any device using any of these three microcontrollers and the Infineon cryptographic library contain the same vulnerability. YubiKey-maker Yubico issued an advisory in coordination with a detailed disclosure report from NinjaLab, the security firm that reverse-engineered the YubiKey 5 series and devised the cloning attack. All YubiKeys running firmware prior to version 5.7 -- which was released in May and replaces the Infineon cryptolibrary with a custom one -- are vulnerable. Updating key firmware on the YubiKey isn't possible. That leaves all affected YubiKeys permanently vulnerable.' -- source: https://it.slashdot.org/story/24/09/03/1810216 Cheers, Peter

Microsoft Says Its Recall Uninstall Option in Windows 11 is Just a Bug
by Peter Reutemann 03 Sep '24

03 Sep '24

'While the latest update to Windows 11 makes it look like the upcoming Recall feature can be easily removed by users, Microsoft tells us it's just a bug and a fix is coming. Deskmodder spotted the change last week in the latest 24H2 version of Windows 11, with KB5041865 seemingly delivering the ability to uninstall Recall from the Windows Features section. "We are aware of an issue where Recall is incorrectly listed as an option under the 'Turn Windows features on or off' dialog in Control Panel," says Windows senior product manager Brandon LeBlanc in a statement to The Verge. "This will be fixed in an upcoming update."' -- source: https://it.slashdot.org/story/24/09/02/2241242 The only way to push a feature that users don't want: make it mandatory!

Rust for Linux Maintainer Steps Down in Frustration With 'Nontechnical Nonsense'
by Peter Reutemann 03 Sep '24

03 Sep '24

'Efforts to add Rust code to the Linux kernel has suffered a setback as one of the maintainers of the Rust for Linux project has stepped down -- citing frustration with "nontechnical nonsense." The Register: Wedson Almeida Filho, a software engineer at Microsoft who has overseen the Rust for Linux project, announced his resignation in a message to the Linux kernel development mailing list. "I am retiring from the project," Filho declared. "After almost four years, I find myself lacking the energy and enthusiasm I once had to respond to some of the nontechnical nonsense, so it's best to leave it up to those who still have it in them." [...] Memory safety bugs are regularly cited as the major source of serious software vulnerabilities by organizations overseeing large projects written in C and C++. So in recent years there's been a concerted push from large developers like Microsoft and Google, and well as from government entities like the US Cybersecurity and Infrastructure Security Agency, to use memory-safe programming languages -- among them Rust. Discussions about adding Rust to Linux date back to 2020 and were realized in late 2022 with the release of Linux 6.1. "I truly believe the future of kernels is with memory-safe languages," Filho's note continued. "I am no visionary but if Linux doesn't internalize this, I'm afraid some other kernel will do to it what it did to Unix."' -- source: https://linux.slashdot.org/story/24/09/02/194205 Cheers, Peter

Public DNS Services
by Lawrence D'Oliveiro 02 Sep '24

02 Sep '24

So I finally got connected to fibre today, and I was pleased to discover that the ISP (https://simplybroadband.co.nz/) offers IPv6 as well. Is this common nowadays? We all know about the public DNS services offered by Google (8.8.8.8, 8.8.4.4) and Cloudflare (1.1.1.1, 1.0.0.1); did you know these addresses have names as well? And of course there are IPv6 addresses to go with the IPv4 ones. Try this command to find out all the related Google DNS services: host -a dns.google. (Yup, that’s “dns.google.”, no “.com” or anything else on the end.) That’s quite a breathtaking list of entries. For Cloudflare, try host one.one.one.one. Note that the “-a” option (“tell me everything”) doesn’t work with Cloudflare; quite a few online services are now imposing restrictions on these “all info” lookups, but clearly not Google, at least not on this domain: obviously they want it to remain easy for people to discover the services they’re offering.

Linux 6.12 To Optionally Display A QR Code During Kernel Panics
by Peter Reutemann 31 Aug '24

31 Aug '24

'A new feature has been submitted for inclusion in Linux 6.12, allowing the display of a QR code when a kernel panic occurs using the DRM Panic handler. This QR code can capture detailed error information that is often missed in traditional text-based panic messages, making it more user-friendly. The feature, written in Rust, is optional and can be enabled via a specific build switch. This implementation follows similar ideas from other operating systems and earlier discussions in the Linux community.' -- source: https://linux.slashdot.org/story/24/08/30/1856206 Cheers, Peter

Malware Infiltrates Pidgin Messenger's Official Plugin Repository
by Peter Reutemann 31 Aug '24

31 Aug '24

'The Pidgin messaging app removed the ScreenShareOTR plugin from its third-party plugin list after it was found to be used to install keyloggers, information stealers, and malware targeting corporate networks. BleepingComputer reports: The plugin was promoted as a screen-sharing tool for secure Off-The-Record (OTR) protocol and was available for both Windows and Linux versions of Pidgin. According to ESET, the malicious plugin was configured to infect unsuspecting users with DarkGate malware, a powerful malware threat actors use to breach networks since QBot's dismantling by the authorities. [...] Those who installed it are recommended to remove it immediately and perform a full system scan with an antivirus tool, as DarkGate may be lurking on their system. After publishing our story, Pidgin's maintainer and lead developer, Gary Kramlich, notified us on Mastodon to say that they do not keep track of how many times a plugin is installed. To prevent similar incidents from happening in the future, Pidgin announced that, from now on, it will only accept third-party plugins that have an OSI Approved Open Source License, allowing scrutiny into their code and internal functionality.' -- source: https://it.slashdot.org/story/24/08/30/2047211 Cheers, Peter

$50 2GB Raspberry Pi 5 comes with a lower price and a tweaked, cheaper CPU
by Peter Reutemann 30 Aug '24

30 Aug '24

'We're many months past the worst of the Raspberry Pi shortages, and the board is finally widely available at its suggested retail price at most sites without wait times or quantity limitations. One sign that the Pi Foundation is feeling more confident about the stock situation: the launch of a new 2GB configuration of the Raspberry Pi 5, available starting today for $50. That's $10 less than the 4GB configuration and $30 less than the 8GB version of the board. Raspberry Pi CEO Eben Upton writes that the 2GB version of the board includes a revised version of the Broadcom BCM2712C1 SoC that is slightly cheaper to manufacture. Upton says that the D0 stepping of the BCM2712C1 strips out some "dark silicon" built-in functionality that the Pi wasn't using but was still taking up space on the silicon die and increasing the cost of the chip. "From the perspective of a Raspberry Pi user, [the chip] is functionally identical to its predecessor: the same fast quad-core processor; the same multimedia capabilities; and the same PCI Express bus that has proven to be one of the most exciting features of the Raspberry Pi 5 platform," Upton writes. "However, it is cheaper to make, and so is available to us at somewhat lower cost. And this, combined with the savings from halving the memory capacity, has allowed us to take $10 out of the cost of the finished product." At $50, the price tag is still north of the baseline $35 price that the Pi started at for many years. The Pi 4 had a 1GB model for $35 when it launched, and there was a $35 2GB model available for a while in 2020, but widespread shortages and supply chain issues led to a "temporary" price increase in late 2021 that is, as of this writing, still in place. At least the 2GB Pi 5 is only $5 more expensive than the 2GB version of the Pi 4, which is still in stock for $45 at many retailers.' -- source: https://arstechnica.com/gadgets/2024/08/new-2gb-raspberry-pi-5-option-knock… Cheers, Peter

'Uncertainty' Drives LinkedIn To Migrate From CentOS To Azure Linux
by Peter Reutemann 30 Aug '24

30 Aug '24

'The Register's Liam Proven reports: Microsoft's in-house professional networking site is moving to Microsoft's in-house Linux. This could mean that big changes are coming for the former CBL-Mariner distro. Ievgen Priadka's post on the LinkedIn Engineering blog, titled Navigating the transition: adopting Azure Linux as LinkedIn's operating system, is the visible sign of what we suspect has been a massive internal engineering effort. It describes some of the changes needed to migrate what the post calls "most of our fleet" from the end-of-life CentOS 7 to Microsoft Azure Linux -- the distro that grew out of and replaced its previous internal distro, CBL-Mariner. This is an important stage in a long process. Microsoft acquired LinkedIn way back in 2016. Even so, as recently as the end of last year, we reported that a move to Azure had been abandoned, which came a few months after it laid off almost 700 LinkedIn staff -- the majority in R&D. The blog post is over 3,500 words long, so there's quite a lot to chew on -- and we're certain that this has been passed through and approved by numerous marketing and management people and scoured of any potentially embarrassing admissions. Some interesting nuggets remain, though. We enjoyed the modest comment that: "However, with the shift to CentOS Stream, users felt uncertain about the project's direction and the timeline for updates. This uncertainty created some concerns about the reliability and support of CentOS as an operating system." [...] There are some interesting technical details in the post too. It seems LinkedIn is running on XFS -- also the RHEL default file system, of course -- with the notable exception of Hadoop, and so the Azure Linux team had to add XFS support. Some CentOS and actual RHEL is still used in there somewhere. That fits perfectly with using any of the RHELatives. However, the post also mentions that the team developed a tool to aid with deploying via MaaS, which it explicitly defines as Metal as a Service. MaaS is a Canonical service, although it does support other distros -- so as well as CentOS, there may have been some Ubuntu in the LinkedIn stack as well. Some details hint at what we suspect were probably major deployment headaches. [...] Some of the other information covers things the teams did not do, which is equally informative.

Microsoft Donates the Mono Project To Wine
by Peter Reutemann 28 Aug '24

28 Aug '24

'Microsoft has decided to donate the Mono Project to the developers of Wine, FOSS that allows Windows applications to run on Unix-like operating systems. "Mono is a software platform designed to allow developers to easily create cross platform applications," notes GameOnLinux's Liam Dawe. "It is an open source implementation of Microsoft's .NET Framework based on the ECMA standards for C# and the Common Language Runtime." "Wine already makes use of Mono and this move makes sense with Microsoft focusing on open-source .NET and other efforts," adds Phoronix's Michael Larabel. "Formally handing over control of the upstream Mono project to WineHQ is a nice move by Microsoft rather than just letting the upstream Mono die off or otherwise forked." Microsoft's Jeff Schwartz announced the move on the Mono website and in a GitHub post: The Mono Project (mono/mono) ('original mono') has been an important part of the .NET ecosystem since it was launched in 2001. Microsoft became the steward of the Mono Project when it acquired Xamarin in 2016. The last major release of the Mono Project was in July 2019, with minor patch releases since that time. The last patch release was February 2024. We are happy to announce that the WineHQ organization will be taking over as the stewards of the Mono Project upstream at wine-mono / Mono - GitLab ( winehq.org) Source code in existing mono/mono and other repos will remain available, although repos may be archived. Binaries will remain available for up to four years. Microsoft maintains a modern fork of Mono runtime in the dotnet/runtime repo and has been progressively moving workloads to that fork. That work is now complete, and we recommend that active Mono users and maintainers of Mono-based app frameworks migrate to .NET which includes work from this fork. We want to recognize that the Mono Project was the first .NET implementation on Android, iOS, Linux, and other operating systems. The Mono Project was a trailblazer for the .NET platform across many operating systems. It helped make cross-platform .NET a reality and enabled .NET in many new places and we appreciate the work of those who came before us. Thank you to all the Mono developers!' -- source: https://tech.slashdot.org/story/24/08/27/2043216 Cheers, Peter

OSMC Vero V
by Lawrence D'Oliveiro 28 Aug '24

28 Aug '24

Just thought I’d mention, I got one of these gadgets <https://osmc.tv/> (the latest “Vero V” model) delivered to my doorstep today. This is to replace a Western Digital “WDTV” media streamer that I got from Dick Smith over a decade ago, that I have been getting more annoyed with. The OSMC software is built on Kodi, with some extra stuff of their own. You should be able to download it and set up your own installation, I just decided to get one of their boxes preassembled and preinstalled. They’re based in the UK. That WDTV box was always fussy about the kinds of files it would play, and what codecs and what bit rates etc it could cope with. When I tried something like .flv files for example, it would play OK if I didn’t try going fast forward/reverse, otherwise it would get stuck. Certain kinds of files could screw it up so badly, the only way to recover was to turn it off and on again. This new box is built on a much more modern Linux base, so I expect its media support will be correspondingly improved. Already it has started playing a .webm file, which the old box wouldn’t even look at. If anybody is curious to know more, just ask. I see there is even an online “store” of addons I can install, for extra capabilities.

The Linux Kernel Gets 60 CVEs A Week
by Lawrence D'Oliveiro 23 Aug '24

23 Aug '24

The Linux kernel team gets 60 logged reports of security vulnerabilities each week, according to longtime developer Greg Kroah-Hartman. He ought to know; he is the point of first contact for such reports, according to <https://www.zdnet.com/article/the-linux-security-team-issues-60-cves-a-week…>. On the bright side, most of them will likely not affect you. The total kernel source tree is up to 38 million lines of code, and your typical OS installation uses only a small fraction of that. To quote GregKH: “Your phone, the most complex beast out there, uses about 4 million lines of code”. They don’t take their time about dealing with vulnerabilities, either: This crew doesn't take embargoes or use pre-announcements. Why not? Because they believe -- with reason -- all these approaches do is lead to information leaks. Instead, they aim to get fixes out to users as quickly as possible. Typically, this is done within a week of having a patch available. This approach ensures that users are promptly notified of security issues and can update their systems accordingly. Another GregKH quote: “If you're not using the latest stable/long-term kernel system, your system is insecure”. Which means, you need to do a kernel update just about every week. The thing is, Kroah-Hartman said, "We have proof this can be done. Debian runs over 80% of the world's servers and they're using stable kernel updates. Android, billions of devices out there, takes every stable kernel update on a couple months lag, but they're doing it and keeping their devices secure. There's nothing more complex than embedded into the system, and there's nothing more common and easy to use than a Debian server.

Litespeed Cache bug exposes millions of WordPress sites to takeover attacks
by Peter Reutemann 22 Aug '24

22 Aug '24

'A critical vulnerability in the LiteSpeed Cache WordPress plugin can let attackers take over millions of websites after creating rogue admin accounts. LiteSpeed Cache is open-source and the most popular WordPress site acceleration plugin, with over 5 million active installations and support for WooCommerce, bbPress, ClassicPress, and Yoast SEO. The unauthenticated privilege escalation vulnerability (CVE-2024-28000) was found in the plugin's user simulation feature and is caused by a weak hash check in LiteSpeed Cache up to and including version 6.3.0.1. Security researcher John Blackbourn submitted the flaw to Patchstack's bug bounty program on August 1. The LiteSpeed team developed a patch and shipped it with LiteSpeed Cache version 6.4, released on August 13. Successful exploitation enables any unauthenticated visitors to gain administrator-level access, which can be used to completely take over websites running vulnerable LiteSpeed Cache versions by installing malicious plugins, changing critical settings, redirecting traffic to malicious websites, distributing malware to visitors, or stealing user data.' -- source: https://www.bleepingcomputer.com/news/security/litespeed-cache-bug-exposes-… Cheers, Peter

“Something has gone seriously wrong,” dual-boot systems warn after Microsoft update
by Peter Reutemann 21 Aug '24

21 Aug '24

'Last Tuesday, loads of Linux users—many running packages released as early as this year—started reporting their devices were failing to boot. Instead, they received a cryptic error message that included the phrase: “Something has gone seriously wrong.” The cause: an update Microsoft issued as part of its monthly patch release. It was intended to close a 2-year-old vulnerability in GRUB, an open source boot loader used to start up many Linux devices. The vulnerability, with a severity rating of 8.6 out of 10, made it possible for hackers to bypass secure boot, the industry standard for ensuring that devices running Windows or other operating systems don’t load malicious firmware or software during the bootup process. CVE-2022-2601 was discovered in 2022, but for unclear reasons, Microsoft patched it only last Tuesday. Tuesday’s update left dual-boot devices—meaning those configured to run both Windows and Linux—no longer able to boot into the latter when Secure Boot was enforced. When users tried to load Linux, they received the message: “Verifying shim SBAT data failed: Security Policy Violation. Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation.” Almost immediately support and discussion forums lit up with reports of the failure. “Note that Windows says this update won't apply to systems that dual-boot Windows and Linux,” one frustrated person wrote. “This obviously isn't true, and likely depends on your system configuration and the distribution being run. It appears to have made some linux efi shim bootloaders incompatible with microcrap efi bootloaders (that's why shifting from MS efi to 'other OS' in efi setup works). It appears that Mint has a shim version that MS SBAT doesn't recognize.” The reports indicate that multiple distributions, including Debian, Ubuntu, Linux Mint, Zorin OS, Puppy Linux, are all affected. Microsoft has yet to acknowledge the error publicly, explain how it wasn’t detected during testing, or provide technical guidance to those affected. Company representatives didn’t respond to an email seeking answers.' -- source: https://arstechnica.com/security/2024/08/a-patch-microsoft-spent-2-years-pr… Cheers, Peter

Check Linux / Unix configuration files for syntax errors
by Peter Reutemann 14 Aug '24

14 Aug '24

Just came across this post, which I thought quite handy: 'In Linux and UNIX system services are configured using various text files located in /etc/ or /usr/local/etc/ directory tree. A typical server system could have dozens of configuration files. You can check your configuration files for syntax errors without starting the server and validate all settings. In some cases, it is possible to check the sanity of specific data/config options and directories. Text files are easier to manage remotely. You can use ssh and a text editor. If there is an error in configuration, the server may not start. It may result in a disaster. This post explains how to quickly find out a syntax error for popular servers and test configuration file for syntax errors.' -- source: https://www.cyberciti.biz/tips/check-unix-linux-configuration-file-for-synt… Cheers, Peter

Almost unfixable “Sinkclose” bug affects hundreds of millions of AMD chips
by Peter Reutemann 12 Aug '24

12 Aug '24

'Security flaws in your computer's firmware, the deep-seated code that loads first when you turn the machine on and controls even how its operating system boots up, have long been a target for hackers looking for a stealthy foothold. But only rarely does that kind of vulnerability appear not in the firmware of any particular computer maker, but in the chips found across hundreds of millions of PCs and servers. Now security researchers have found one such flaw that has persisted in AMD processors for decades, and that would allow malware to burrow deep enough into a computer's memory that, in many cases, it may be easier to discard a machine than to disinfect it. At the Defcon hacker conference, Enrique Nissim and Krzysztof Okupski, researchers from the security firm IOActive, plan to present a vulnerability in AMD chips they're calling Sinkclose. The flaw would allow hackers to run their own code in one of the most privileged modes of an AMD processor, known as System Management Mode, designed to be reserved only for a specific, protected portion of its firmware. IOActive's researchers warn that it affects virtually all AMD chips dating back to 2006, or possibly even earlier.' -- source: https://arstechnica.com/security/2024/08/almost-unfixable-sinkclose-bug-aff… Cheers, Peter

Mozilla Wants You To Love Firefox Again
by Peter Reutemann 12 Aug '24

12 Aug '24

'Mozilla's interim CEO Laura Chambers "says the company is reinvesting in Firefox after letting it languish in recent years," reports Fast Company, "hoping to reestablish the browser as independent alternative to the likes of Google's Chrome and Apple's Safari. "But some of those investments, which also include forays into generative AI, may further upset the community that's been sticking with Firefox all these years..." Chambers acknowledges that Mozilla lost sight of Firefox in recent years as it chased opportunities outside the browser, such as VPN service and email masking. When she replaced Mitchell Baker as CEO in February, the company scaled back those other efforts and made Firefox a priority again. "Yes, Mozilla is refocusing on Firefox," she says. "Obviously, it's our core product, so it's an important piece of the business for us, but we think it's also really an important part of the internet." Some of that focus involves adding features that have become table-stakes in other browsers. In June, Mozilla added vertical tab support in Firefox's experimental branch, echoing a feature that Microsoft's Edge browser helped popularize three years ago. It's also working on tab grouping features and an easier way to switch between user profiles. Mozilla is even revisiting the concept of web apps, in which users can install websites as freestanding desktop applications. Mozilla abandoned work on Progressive Web Apps in Firefox a few years ago to the dismay of many power users, but now it's talking with community members about a potential path forward. "We haven't always prioritized those features as highly as we should have," Chambers says. "That's been a real shift that's been very felt in the community, that the things they're asking for . . . are really being prioritized and brought to life." Firefox was criticized for testing a more private alternative to tracking cookies which could make summaries of aggregated data available to advertisers. (Though it was only tested on a few sites, "Privacy-Preserving Attribution" was enabled by default.) But EFF staff technologist Lena Cohen tells Fast Company that approach was "much more privacy-preserving" than Google's proposal for a "Privacy Sandbox." And according to the article, "Mozilla's system only measures the success rate of ads — it doesn't help companies target those ads in the first place — and it's less susceptible to abuse due to limits on how much data is stored and which parties are allowed to access it." In June, Mozilla also announced its acquisition of Anonym, a startup led by former Meta executives that has its own privacy-focused ad measurement system. While Mozilla has no plans to integrate Anonym's tech in Firefox, the move led to even more anxiety about the kind of company Mozilla was becoming. The tension around Firefox stems in part from Mozilla's precarious financial position, which is heavily dependent on royalty payments from Google. In 2022, nearly 86% of Mozilla's revenue came from Google, which paid $510 million to be Firefox's default search engine. Its attempts to diversify, through VPN service and other subscriptions, haven't gained much traction. Chambers says that becoming less dependent on Google is "absolutely a priority," and acknowledges that building an ad-tech business is one way of doing that. Mozilla is hoping that emerging privacy regulations and wider adoption of anti-tracking tools in web browsers will increase demand for services like Anonym and for systems like Firefox's privacy-preserving ad measurements. Other revenue-generating ideas are forthcoming. Chambers says Mozilla plans to launch new products outside of Firefox under a "design sprint" model, aimed at quickly figuring out what works and what doesn't. It's also making forays into generative AI in Firefox, starting with a chatbot sidebar in the browser's experimental branch. Chambers "says to expect a bigger marketing push for Firefox in the United States soon, echoing a 'Challenge the default' ad campaign that was successful in Germany last summer. Mozilla's nonprofit ownership structure, and the idea that it's not beholden to corporate interests, figures heavily into those plans."' -- source: https://tech.slashdot.org/story/24/08/11/1635254 Cheers, Peter

Ubuntu Will Start Shipping With the Latest Upstream Linux Kernel - Even Release Candidates
by Peter Reutemann 12 Aug '24

12 Aug '24

'Here's a question from the blog OMG Ubuntu. "Ever get miffed reading about a major new Ubuntu release only to learn it doesn't come with the newest Linux kernel? "Well, that'll soon be a thing of the past." Canonical's announced a big shift in kernel selection process for future Ubuntu release, an "aggressive kernel version commitment policy" pivot that means it will ship the latest upstream kernel code in development at the time of a new Ubuntu release. Yes, even if that upstream kernel hasn't yet seen a formal stable release (and received the requisite newspaper-graphic-topped rundown on this blog). Which is a huge change. Currently, new Ubuntu releases include the most recent stable Linux kernel release at the time of the kernel freeze milestone in the Ubuntu development cycle. Here's the official announcement by Canonical's Brett Grandbois. "Ubuntu will now ship the absolute latest available version of the upstream Linux kernel at the specified Ubuntu release freeze date, even if upstream is still in Release Candidate status..." It is actually expected that Late Releases will be the exception rather than the norm and in most releases these guidelines will not be necessary as the upstream kernel will release with enough time for the Ubuntu kernel to stabilize. However, adopting a more aggressive kernel version commitment policy does require us to be prepared for a possible Late Release situation and therefore informing the community on what they can expect.

You can kick the alpha tires on System76’s Cosmic, a new Linux desktop
by Peter Reutemann 09 Aug '24

09 Aug '24

'System76 has released an alpha version of its Cosmic desktop environment for Linux and Unix-like systems. The Linux hardware firm isn't targeting only its customers with its GNOME replacement; it also hopes to get distro maintainers and app makers on board with its Rust-built, UX-focused desktop. While the Cosmic desktop will be built into the Linux vendor's Pop!_OS (which is also in the alpha ISO), it's also available to other systems, as you might expect. System76 provides drop-in instructions for Fedora and Arch Linux installs, among others. System76 says it is "excited to see COSMIC integration elevate Linux as a whole," along with what results "from making UX-building more accessible." By building Cosmic natively in the Rust language, System76 also intends to provide a more stable and memory-safe environment for apps. Cosmic shows deep attention to tiling, keyboard shortcuts, and panel and dock customization, as has been present on its Pop!_OS. I'm a bit of a boring side-by-side, single-workspace type; Gardiner Bryant on YouTube went deeper into the Cosmic alpha's tiling, panels, and GTK app acceptance. I found that getting Cosmic into a reasonable shape I could work from, and picking up its keyboard window shortcuts, was easier than with either KDE or GNOME. One thing System76 made clear in its push for Cosmic is its readiness for more deeply integrated themes. System76 offered a few examples in its press materials, and I must admit a fondness for its over-the-top examples. -- source: https://arstechnica.com/gadgets/2024/08/you-can-kick-the-alpha-tires-on-sys… Cheers, Peter

Chrome’s Manifest V3, and its changes for ad blocking, are coming real soon
by Peter Reutemann 07 Aug '24

07 Aug '24

'Google Chrome's long, long project to implement a new browser extension platform is seemingly going to happen, for real, after six years of cautious movement. One of the first ways people are seeing this is if they use uBlock Origin, a popular ad-blocking extension, as noted by Bleeping Computer. Recently, Chrome users have seen warnings pop up that "This extension may soon no longer be supported," with links asking the user to "Remove or replace it with similar extensions" from Chrome's Web Store. You might see a similar warning on some extensions if you head to Chrome's Extensions page (chrome://extensions). What's happening is Chrome preparing to make Manifest V3 required for extensions that want to run on its platform. First announced in 2018, the last word on Manifest V3 was that V2 extensions would start being nudged out in early June on the Beta, Dev, and Canary update channels. Users will be able to manually re-enable V2 extensions "for a short time," Google has said, "but over time, this toggle will go away as well." The shift for enterprise Chrome deployments is expected to be put off until June 2025. ' -- source: https://arstechnica.com/gadgets/2024/08/chromes-manifest-v3-and-its-changes… Cheers, Peter

Germany to Fund Open Source Software Maintainers Through New Fellowship Program

'If you’re of the ilk to complain about governments giving money away and what that means for taxpayers, the Germans — or at least their government — are doing this because it will be good for the economy, meaning they think it’ll make folks better able to pay their taxes rather just empty their pockets for the taxman. This is also why they’ve already spending a substantial amount of money to help fund over 40 FOSS projects. “Open source infrastructure is the backbone of our digital world – and the work of the people who maintain it is essential to ensuring the security and availability of this global resource,” Mirko Swillus wrote in a blog that was published on Thursday. “They lead project development, review changes, manage community interactions, and tackle security issues.” Swillus is program manager at Sovereign Tech Fund, and the blog was to announce fund’s new Fellowship for Maintainers program. “With this new fellowship program, we’re directly investing in the people behind the code by paying maintainers of critical open source components for their work,” he wrote.' -- source: https://fossforce.com/2024/08/germany-to-fund-open-source-software-maintain… Cheers, Peter

How to replace Windows with Linux Mint on your PC
by Peter Reutemann 05 Aug '24

05 Aug '24

'Are you sick of Windows fouling up? Do you want to try something different? Then, it's time to try the best Linux desktop, Linux Mint 22. I've used more operating systems than you can shake a stick at. I cut my teeth on IBM 360/OS in the 1970s. Since then, I've used every Apple and Microsoft operating system you've heard of, and many you've never known, such as A/UX and Microsoft Xenix. I've also used well over 100 different Unix and Linux distributions. So, when I say Linux Mint 22 -- the latest long-term support (LTS) version of Linux Mint -- is not just the best Linux desktop, but the best desktop, it means something. - Materials needed: Windows PC, internet connection, and a DVD-RW or USB stick with 3GB or more storage - Estimated time: 2 hours - Estimated cost: $5' -- source: https://www.zdnet.com/article/how-to-replace-windows-with-linux-mint-on-you… With the continuing enshittification [1] of Windows, maybe a good time to get folks moved to a less intrusive operating system...

First Look at Serpent OS: Minimal GNOME Desktop and Rust-Based Package Manager
by Peter Reutemann 02 Aug '24

02 Aug '24

'The wait is finally over and Ikey Doherty’s long-anticipated Serpent OS distribution has an ISO image that people can download and test on bare metal hardware or virtual machines to see what the fuss is all about. Four years ago I broke news that Ikey Doherty is making a new distro called Serpent Linux (it was later changed to Serpent OS) aiming to provide the Linux community with a truly modern distribution for people who want to just use Linux. The name of the distribution is inspired by the Serpent game created by Ikey Doherty. At that time, Serpent OS was supposed to ship with the KDE Plasma desktop environment by default, but things have changed and GNOME was chosen as the default for the initial release. The first pre-alpha ISO image includes the older GNOME 45.3 release, but I’m sure the final release will use a more recent version. Serpent OS offers a minimal GNOME desktop experience with only a handful of apps pre-installed, such as the Mozilla Firefox web browser, GNOME Console terminal emulator, GNOME Text Editor text editing app, Zed code editor, GNOME’s Loupe image viewer, and GNOME Extensions. However, Serpent OS supports Flatpak apps if you need to install the apps you need, but Flatpak support is not installed by default in this pre-alpha release.' -- source: https://9to5linux.com/first-look-at-serpent-os-minimal-gnome-desktop-and-ru… Cheers, Peter

The Unintended Consequences Linux’s Wayland Adoption Will Have on BSD
by Peter Reutemann 31 Jul '24

31 Jul '24

'Like most people who use Linux as their daily driver, I’ve been pleased lately to see that Wayland is finally getting some serious traction and is on its way to being the default display server for most mainstream Linux distributions. It’s been a long trip from the days when we first heard that X was on its way out and that Wayland was on its way in — 15 years as a matter of fact — so the better performance, more svelte code base, enhanced security, and all of the other advantages that Wayland brings to the table being just about here for some of us, and already here for others, is indeed good news. But before we pop the cork on the champagne bottles and start the celebrations, perhaps we should consider that this good news for Linux might not be good news for those running BSD or one of the Unixes, which is something that normally would never occur to me to think about since I’ve never tried to use BSD. The only reason I’m thinking about it now is because this weekend I ran across a post by Chris Siebenmann, a Unix systems administrator at the University of Toronto’s CS Labs. Being a Unix guy by day (and I suspect a BSD guy by night), he’s all on what Wayland on Linux means to BSD/Unix stuck on X, and he’s been thinking about what Linux’s move to Wayland is going to mean for desktop BSDs and Unixes. “Once upon a time, the future of Unix desktops looked fairly straightforward,” he wrote. “Everyone ran on X, so the major threat to cross-Unix portability in major desktops was the use of Linux only APIs, which became especially D-Bus and systemd related things. Unix desktops that were less attached to tight integration with the Linux environment would probably stay easily available on FreeBSD, OpenBSD, and so on.” The main thing I got from that is that for a long time, the BSDs have benefited somewhat from Linux. In this case, because both operating systems use X, it was relatively easy (“relatively” probably being the key word here) to port most popular “Linux” desktop environments to BSD. The trouble is, according to Siebenmann, those days might be coming to an end.' -- source: https://fossforce.com/2024/07/the-unintended-consequences-linuxs-wayland-ad… Cheers, Peter

LZ4 Compression Algorithm Gets Multi-Threaded Update
by Peter Reutemann 29 Jul '24

29 Jul '24

'Slashdot reader Seven Spirals brings news about the lossless compression algorithm LZ4: The already wonderful performance of the LZ4 compressor just got better with multi-threaded additions to it's codebase. In many cases, LZ4 can compress data faster than it can be written to disk giving this particular compressor some very special applications. The Linux kernel as well as filesystems like ZFS use LZ4 compression extensively. This makes LZ4 more comparable to the Zstd compression algorithm, which has had multi-threaded performance for a while, but cannot match the LZ4 compressor for speed, though it has some direct LZ4. >From Linuxiac.com: - On Windows 11, using an Intel 7840HS CPU, compression time has improved from 13.4 seconds to just 1.8 seconds — a 7.4 times speed increase. - macOS users with the M1 Pro chip will see a reduction from 16.6 seconds to 2.55 seconds, a 6.5 times faster performance. - For Linux users on an i7-9700k, the compression time has been reduced from 16.2 seconds to 3.05 seconds, achieving a 5.4 times speed boost... The release supports lesser-known architectures such as LoongArch, RISC-V, and others, ensuring LZ4's portability across various platforms.

What Happens If You Connect Windows XP To the Internet In 2024?

'Long-time Slashdot reader sandbagger writes: Have you ever wondered if it's true you can instantly get malware? In this video, a person connects an XP instance directly to the internet with no firewall to see just how fast it gets compromised by malware, rootkits, malicious services and new user accounts. The answer — fast! Malwarebytes eventually finds eight different viruses/Trojan horses -- and a DNS changer. (One IP address leads back to the Russian federation.) It's fun to watch -- within just a few hours a new Windows user has even added themself. And for good measure, he also opens up Internet Explorer... - Windows XP -- very insecure, they conclude at the end of the video. Very easy for random software from the internet to get more privileges than you, and it is very hard to solve that. - Also, just out of curiosity I tried this on Windows 7.

Secure Boot is completely broken on 200+ models from 5 big device makers
by Peter Reutemann 26 Jul '24

26 Jul '24

'On Thursday, researchers from security firm Binarly revealed that Secure Boot is completely compromised on more than 200 device models sold by Acer, Dell, Gigabyte, Intel, and Supermicro. The cause: a cryptographic key underpinning Secure Boot on those models that was compromised in 2022. In a public GitHub repository committed in December of that year, someone working for multiple US-based device manufacturers published what’s known as a platform key, the cryptographic key that forms the root-of-trust anchor between the hardware device and the firmware that runs on it. The repository was located at https://github.com/raywu-aaeon/Ryzen2000_4000.git, and it's not clear when it was taken down. The repository included the private portion of the platform key in encrypted form. The encrypted file, however, was protected by a four-character password, a decision that made it trivial for Binarly, and anyone else with even a passing curiosity, to crack the passcode and retrieve the corresponding plain text. The disclosure of the key went largely unnoticed until January 2023, when Binarly researchers found it while investigating a supply-chain incident. Now that the leak has come to light, security experts say it effectively torpedoes the security assurances offered by Secure Boot. “It’s a big problem,” said Martin Smolár, a malware analyst specializing in rootkits who reviewed the Binarly research and spoke to me about it. “It’s basically an unlimited Secure Boot bypass for these devices that use this platform key. So until device manufacturers or OEMs provide firmware updates, anyone can basically… execute any malware or untrusted code during system boot. Of course, privileged access is required, but that’s not a problem in many cases.”' -- source: https://arstechnica.com/security/2024/07/secure-boot-is-completely-compromi… Cheers, Peter

distrobox
by Peter Reutemann 26 Jul '24

26 Jul '24

Just came across distrobox, which seems a useful extension to container managers like docker/podman/lilipod, allowing you to run other distros in your shell: 'Use any Linux distribution inside your terminal. Enable both backward and forward compatibility with software and freedom to use whatever distribution you’re more comfortable with. Distrobox uses podman, docker or lilipod to create containers using the Linux distribution of your choice. The created container will be tightly integrated with the host, allowing sharing of the HOME directory of the user, external storage, external USB devices and graphical apps (X11/Wayland), and audio.' -- source: https://distrobox.it/ That should be especially useful for people working in environments where they are forced to use a specific host OS. As long as they have one of the supported container managers available, they can easily switch! Cheers, Peter

Anyone can Access Deleted and Private Repository Data on GitHub
by Peter Reutemann 26 Jul '24

26 Jul '24

'You can access data from deleted forks, deleted repositories and even private repositories on GitHub. And it is available forever. This is known by GitHub, and intentionally designed that way. This is such an enormous attack vector for all organizations that use GitHub that we’re introducing a new term: Cross Fork Object Reference (CFOR). A CFOR vulnerability occurs when one repository fork can access sensitive data from another fork (including data from private and deleted forks). Similar to an Insecure Direct Object Reference, in CFOR users supply commit hashes to directly access commit data that otherwise would not be visible to them.

It Never Rains But It Pours
by Lawrence D'Oliveiro 24 Jul '24

24 Jul '24

Instructive to read this notice <https://rimuhosting.com/maintenance.jsp?server_maint_oid=5241959612&sn_oid=…> about progress in fixing an issue in the Dallas co-lo centre for Rimu hosting. As a customer, I wasn’t affected (though I could have been), and I have no complaints with the way this was handled--it was great that they kept customers like me apprised of developments like this. The interesting part is how a single initial failure can lead to a cascade of other failures. From the description, the original problem was a breakdown of a transformer feeding power from the grid. To allow it to be repaired, the power was switched to a backup generator. The generator then shut down with a belt problem. So power went to UPS batteries. These ran flat before the generator could be brought back to operation. So various parts of the facility were left without power. After power was restored, it was discovered that some (network?) switches had failed to come up. So a bunch of physical boxes holding customers’ VMs had to be physically moved to a different location where they could get connectivity again. From that point, the disruption was (mostly) over as far as customers were concerned, though there was obviously still work to be done to get the infrastructure back to its normal state. I think that a lot of theoretical statistical modelling of the odds of system failures tends to assume that failures of individual components will be independent of each other. Yet time and time again in the real world, we discover that this is not the case.

Switzerland Now Requires All Government Software To Be Open Source
by Peter Reutemann 24 Jul '24

24 Jul '24

'Switzerland has enacted the "Federal Law on the Use of Electronic Means for the Fulfillment of Government Tasks" (EMBAG), mandating open-source software (OSS) in the public sector to enhance transparency, security, and efficiency. "This new law requires all public bodies to disclose the source code of software developed by or for them unless third-party rights or security concerns prevent it," writes ZDNet's Steven Vaughan-Nichols. "This 'public money, public code' approach aims to enhance government operations' transparency, security, and efficiency." From the report: Making this move wasn't easy. It began in 2011 when the Swiss Federal Supreme Court published its court application, Open Justitia, under an OSS license. The proprietary legal software company Weblaw wasn't happy about this. There were heated political and legal fights for more than a decade. Finally, the EMBAG was passed in 2023. Now, the law not only allows the release of OSS by the Swiss government or its contractors, but also requires the code to be released under an open-source license "unless the rights of third parties or security-related reasons would exclude or restrict this." Professor Dr. Matthias Sturmer, head of the Institute for Public Sector Transformation at the Bern University of Applied Sciences, led the fight for this law. He hailed it as "a great opportunity for government, the IT industry, and society." Sturmer believes everyone will benefit from this regulation, as it reduces vendor lock-in for the public sector, allows companies to expand their digital business solutions, and potentially leads to reduced IT costs and improved services for taxpayers. In addition to mandating OSS, the EMBAG also requires the release of non-personal and non-security-sensitive government data as Open Government Data (OGD). This dual "open by default" approach marks a significant paradigm shift towards greater openness and practical reuse of software and data. Implementing the EMBAG is expected to serve as a model for other countries considering similar measures. It aims to promote digital sovereignty and encourage innovation and collaboration within the public sector. The Swiss Federal Statistical Office (BFS) is leading the law's implementation, but the organizational and financial aspects of the OSS releases still need to be clarified.

Linux Mint 22 “Wilma” Is Now Available for Download, Here’s What’s New
by Peter Reutemann 24 Jul '24

24 Jul '24

'Linux Mint 22 is now available for download as the latest stable release of this popular Ubuntu-based operating system for the masses featuring the Cinnamon, Xfce, and MATE desktop environments. Dubbed “Wilma”, Linux Mint 22 is based on the Ubuntu 24.04 LTS (Noble Numbat) operating system series and uses the Linux 6.8 kernel. It will receive security updates until 2029 and new kernel versions as they’re available upstream in the Ubuntu 24.04 LTS repositories. The flagship edition features the latest Cinnamon 6.2 desktop environment while the Xfce and MATE editions ship with the Xfce 4.18 and MATE 1.26 desktop environments. The Wayland session in the Cinnamon edition is still in an experimental state and Linux Mint 22 Cinnamon will default to X11. Linux Mint 22 comes with PipeWire as the default sound server, support for the new Debian DEB822 format, GTK4 support for themes, improved HiDPI support during boot, better language support, artwork improvements, and FAT32 in File System Transposition mode support for the ISO images. Software-wise, Linux Mint 22 features the Mozilla Thunderbird email client as a native DEB package, a new GNOME Online Accounts GTK independent XApp to support the Online Accounts functionality, and a new Web App called Matrix, which is preinstalled by default and connects you to the Matrix chat network. Furthermore, it features JXL (JPEG-XL) image support in the Pix image viewer, a confirmation dialog pop-up when deleting a snapshot in the Timeshift backup tool, the ability to configure the default position of newly created notes in the Sticky note-taking app, and support for the Xed text editor to duplicate selected text. It also disables unverified Flatpak apps by default in the Software Manager app, which received some welcome changes like improved multi-threading, a new preferences page, and a banner slideshow. In addition, Software Manager now loads faster than before and the main window appears instantly. On top of that, Linux Mint 22 comes with a new package called xapp-thumbnailer-gimp that provides a thumbnailer for GIMP (.xcf) files and an updated xfce4-xapp-status-plugin tray applet that lets you configure icon sizes for full-color and symbolic icons.' -- source: https://9to5linux.com/linux-mint-22-wilma-is-now-available-for-download-her… Cheers, Peter

Apache Software Foundation is Retiring its Feather Logo
by Peter Reutemann 23 Jul '24

23 Jul '24

'The Apache Software Foundation (ASF) has announced plans to evolve its corporate logo and brand system to better represent its "community over code" ethos and promote inclusivity. Why? Because the ASF took seriously concerns raised by Natives in Tech and other members of the open-source community regarding the appropriateness of using Indigenous imagery. So, the ASF will retire its iconic feather logo, which has been a central part of the foundation's identity since 1999. The organization acknowledges that, as a non-Indigenous entity, it is inappropriate to continue using Indigenous themes or language in its branding. The group also realizes that the logo has been very popular for almost 30 years, but they feel this is the right thing to do. This comes after ASF changed the name of its flagship event to Community Over Code from ApacheCon. The ASF's Marketing and publicity team, along with a Branding Steering Committee composed of ASF Members, is collaborating with branding and design vendors to develop a new logo. This new visual identity will embody the Foundation's history of providing software for the public good while reflecting its global contributor base. The decision to update the brand extends beyond the logo. Changes also apply to ASF open-source projects that currently use Indigenous imagery. It will not--I and the ASF repeat--not change the Apache License or any released software. ' -- source: https://opensourcewatch.beehiiv.com/p/apache-software-foundation-retiring-f… Cheers, Peter

Imperfect, Linux-powered, DIY smart TV is the embodiment of ad fatigue
by Peter Reutemann 23 Jul '24

23 Jul '24

'Smart TV owners have been subjected to a growing amount of ads and tracking. Ad fatigue, only worsened by a trend that sees streaming providers trying to force customers into subscriptions with commercials, is understandable. We’re at the point where someone would rather use a broken laptop dangling off a TV than be subjected to the watchful eye of the TV's native operating system. Earlier this month, as spotted by Tom’s Hardware, a blogger named Carl Riis, who says he’s a software engineer, shared his DIY project, a Linux-based “smart TV.” Riis’ project doesn’t stand out because it’s the most unique, clever, or clean. In fact, if you’re the type of person willing to pay a lot for TVs with strong aesthetic appeal, like TVs that can look like artwork or appear transparent, you’ll be put off by the EarlGreyTV. The system uses an old Lenovo laptop that has a broken keyboard and is attached to a TV by a string. As Riis wrote: “This may look a little insane, but it has been a great way to keep things neat while retaining access to the laptop."' -- source: https://arstechnica.com/gadgets/2024/07/broken-linux-laptop-makes-for-a-fin… Cheers, Peter

Microsoft: Linux Is the Top Operating System on Azure Today
by Peter Reutemann 23 Jul '24

23 Jul '24

'Azure used to be a cloud platform dedicated to Windows. Now, it's the most widely used operating system on Microsoft Azure. The New Stack's Joab Jackson writes: These days, Microsoft expends considerable effort that Linux runs as smoothly as possible on Azure, according to a talk given earlier this year at the Linux Foundation Open Source Summit given by two Microsoft Azure Linux Platforms Group program managers, Jack Aboutboul, and Krum Kashan. "Linux is the #1 operating system in Azure today," Aboutoul said. And all must be supported in a way that Microsoft users have come to expects. Hence, the need for the Microsoft's Linux Platforms Group, which provides support Linux to both the internal customers and to Azure customers. These days, the duo of engineers explained, Microsoft knows about as much as anyone about how to operate Linux at hyperscale. [...] As of today, there are hundreds of Azure and Azure-based services running on Linux, including the Azure Kubernetes Service (AKS), OpenAI, HDInsight, and many of the other database services. "A lot of the infrastructure powering everything else is running on Linux," Aboutoul said. "They're different flavors of Linux running all over the place," Aboutoul said. To run these services, Microsoft maintains its own kernel, Azure Linux, and in 2023 the company released its own version of Linux, Azure Linux. But Azure Linux is just a small portion of all the other flavors of Linux running on Azure, all of which Microsoft must work with to support. Overall, there are about 20,000 third-party Software as a Service (SaaS) packages in the Azure marketplace that rely on some Linux distribution. And when things go wrong, it is the Azure service engineers who get the help tickets. The company keeps a set of endorsed Linux distributions, which include Red Hat Enterprise Linux, Debian, Flatcar, Suse, Canonical, and Oracle Linux and CentOS (as managed by OpenLogic, not Red Hat). [...] Overall, the company gets about 1,000 images a month from these endorsed partners alone. Many of the distributions have multiple images (Suse has a regular one, and another one for high-performance computing, for instance).

Nvidia Will Fully Transition To Open-Source GPU Kernel Modules With R560 Drivers
by Peter Reutemann 19 Jul '24

19 Jul '24

'Nvidia is ready to fully transition to open-source Linux GPU kernel drivers, starting with the R555 series and planning a complete shift with the R560 series. The open-source kernel modules will only be available for select newer GPUs, while older architectures like Maxwell, Pascal, and Volta must continue using proprietary drivers. TechSpot reports: According to Nvidia, the open-source GPU kernel modules have helped deliver "equivalent or better" application performance compared to its proprietary kernels. The company has also added new features like Heterogeneous Memory Management (HMM) support, confidential computing, and the coherent memory architectures of the Grace platform to its open-source kernels. [...] For compatible GPUs, the default version of the driver installed by all methods is switching from proprietary to open-source. However, users will have the ability to manually select the closed-source modules if they are still available for their platform. Unfortunately, the open-source kernel modules are not available for GPUs from the older Maxwell, Pascal, and Volta architectures, meaning people still running a GTX 980 or GTX 1080 will have to continue using Nvidia's proprietary drivers. For mixed deployments with older and newer GPUs in the same system, Nvidia recommends continuing to use the proprietary driver for full compatibility. "Nvidia has moved most of its proprietary functions into a proprietary, closed-source firmware blob," adds Ars Technica's Kevin Purdy. "The parts of Nvidia's GPUs that interact with the broader Linux system are open, but the user-space drivers and firmware are none of your or the OSS community's business."

SUSE Requests openSUSE to Rebrand
by Peter Reutemann 18 Jul '24

18 Jul '24

'Believe it or not, an unexpected conflict has arisen in the openSUSE community with its long-time supporter and namesake, the SUSE company. At the heart of this tension lies a quiet request that has stirred not-so-quiet ripples across the open source landscape: SUSE has formally asked openSUSE to discontinue using its brand name. Richard Brown, a key figure within the openSUSE project, shared insights into the discussions that have unfolded behind closed doors. Despite SUSE’s request’s calm and respectful tone, the implications of not meeting it could be far-reaching, threatening the symbiotic relationship that has benefited both entities over the years. Let’s face it: SUSE has been more than just a namesake for openSUSE; it has actively provided resources and support far beyond what it would ordinarily need for its business operations. This generosity has fostered a thriving openSUSE project that has excelled under SUSE’s goodwill and informal support, including contributions made by SUSE employees on company time. However, the recent request for a branding separation has overshadowed this partnership. If openSUSE does not handle this request with the sensitivity and cooperation it demands, the project risks not just a reduction in support from SUSE but a potential shift in priorities away from it. The “Factory first” policy, a cornerstone of the engineering synergy between SUSE and openSUSE, could also be scrutinized, emphasizing the gravity of the current situation.' -- source: https://linuxiac.com/suse-requests-opensuse-to-rebrand/ Cheers, Peter

No more boot loader: Please use the kernel instead
by Peter Reutemann 09 Jul '24

09 Jul '24

'We are working on a new scheme to replace the GRUB bootloader with a fast, secure, Linux-based, user-space solution: nmbl (for no more boot loader). Most people are familiar with GRUB, a powerful, flexible, fully-featured bootloader that is used on multiple architectures (x86_64, aarch64, ppc64le OpenFirmware). Although GRUB is quite versatile and capable, its features create complexity that is difficult to maintain, and that both duplicate and lag behind the Linux kernel while also creating numerous security holes. On the other hand, the Linux kernel, which has a large developer base, benefits from fast feature development, quick responses to vulnerabilities and greater overall scrutiny. We (Red Hat boot loader engineering) will present our solution to this problem, which is to use the Linux kernel as its own bootloader. Loaded by the EFI stub on UEFI, and packed into a unified kernel image (UKI), the kernel, initramfs, and kernel command line, contain everything they need to reach the final boot target. All necessary drivers, filesystem support, and networking are already built in and code duplication is avoided. We will showcase the work done so far, and ask you for your feedback and use cases.' -- source: https://pretalx.com/devconf-cz-2024/talk/W3AVCT/ -- video: https://www.youtube.com/watch?v=ywrSDLp926M Cheers, Peter

FreeBSD Contributor Mocks Gloomy Predictions for the Open Source Movement
by Peter Reutemann 08 Jul '24

08 Jul '24

'In Communications of the ACM,/em>, long-time FreeBSD contributor Poul-Henning Kamp mocks the idea that the free and open-source software has "come apart" and "will end in tears and regret." Economists and others focused on money — like my bank — have had a lot of trouble figuring out the free and open source software (FOSS) phenomenon, and eventually they seem to have reached the conclusion that it just makes no sense. So, they go with the flow. Recently, very serious people in the FOSS movement have started to write long and thoughtful opinion pieces about how it has all come apart and will end in tears and regret. Allow me to disagree... What follows is a humorous history of how the Open Source movement bested a series of ill-conceived marketing failures starting after the "utterly bad" 1980s when IBM had an "unimaginably huge monopoly" — and an era of vendor lock-in from companies trying to be the next IBM: Out of that utter market failure came Minix, (Net/Free/Open)BSD, and Linux, at a median year of approximately 1991. I can absolutely guarantee that if we had been able to buy a reasonably priced and solid Unix for our 32-bit PCs — no strings attached — nobody would be running FreeBSD or Linux today, except possibly as an obscure hobby. Bill Gates would also have had a lot less of our money... The essay moves on to when "that dot-com thing happened, fueled by the availability of FOSS operating systems, which did a much better job than any operating system you could buy — not just for the price, but in absolute terms of performance on any given piece of hardware. Thus, out of utter market failure, the FOSS movement was born." And ultimately, the essay ends with our present day, and the phenomenon of companies that "make a business out of FOSS or derivatives thereof..." The "F" in FOSS was never silent. In retrospect, it seems clear that open source was not so much the goal itself as a means to an end, which is freedom: freedom to fix broken things, freedom from people who thought they could clutch the source code tightly and wield our ignorance of it as a weapon to force us all to pay for and run Windows Vista. But the FOSS movement has won what it wanted, and no matter how much oldsters dream about their glorious days as young revolutionaries, it is not coming back; the frustrations and anger of IT in 2024 are entirely different from those of 1991. One very big difference is that more people have realized that source code is a liability rather than an asset. For some, that realization came creeping along the path from young teenage FOSS activists in the late 1990s to CIOs of BigCorp today. For most of us, I expect, it was the increasingly crushing workload of maintaining legacy code bases...' -- source: https://news.slashdot.org/story/24/07/07/0243241 Cheers, Peter

“RegreSSHion” vulnerability in OpenSSH gives attackers root on Linux
by Peter Reutemann 03 Jul '24

03 Jul '24

'Researchers have warned of a critical vulnerability affecting the OpenSSH networking utility that can be exploited to give attackers complete control of Linux and Unix servers with no authentication required. The vulnerability, tracked as CVE-2024-6387, allows unauthenticated remote code execution with root system rights on Linux systems that are based on glibc, an open source implementation of the C standard library. The vulnerability is the result of a code regression introduced in 2020 that reintroduced CVE-2006-5051, a vulnerability that was fixed in 2006. With thousands, if not millions, of vulnerable servers populating the Internet, this latest vulnerability could pose a significant risk. [...] The vulnerability affects the following: - OpenSSH versions earlier than 4.4p1 are vulnerable to this signal handler race condition unless they are patched for CVE-2006-5051 and CVE-2008-4109. - Versions from 4.4p1 up to, but not including, 8.5p1 are not vulnerable due to a transformative patch for CVE-2006-5051, which made a previously unsafe function secure. - The vulnerability resurfaces in versions from 8.5p1 up to, but not including, 9.8p1 due to the accidental removal of a critical component in a function.' -- source: https://arstechnica.com/security/2024/07/regresshion-vulnerability-in-opens… OpenSSH 9.8 was released July 1st: https://www.openssh.com/ Cheers, Peter

Made Move To Wayland
by Lawrence D'Oliveiro 01 Jul '24

01 Jul '24

I’d been running Wayland OK on my laptop for some months now, but I held off putting it on my main machine for one reason: when I logged into a Wayland session, Emacs would not recognize my Compose key (which I have set to Caps Lock). Today I finally figured out I have to install the “emacs-pgtk” package instead of “emacs-gtk”; the former is built with a version of GTK that works with Wayland. And yes, my Compose key works again. Still have to get used to slightly different input behaviour: previously, once I hit Compose, nothing would appear until I finished the whole key sequence. Now it echoes each keystroke immediately as I type it, in place, overwriting the previous echo (starting with an underline for the Compose key itself), then when I have typed the last key, it overwrites the echo area with the final character.

From Jupyter To JupyterLab
by Lawrence D'Oliveiro 28 Jun '24

28 Jun '24

I’ve been using Jupyter <https://jupyter.org/> as a convenient basis for “scratchpad” programming (not just in Python, but also some other languages) for a while now. I had heard about this next-generation “JupyterLab” thing they were working on, but always held off trying it out. Then I did my usual monthly upgrade of Debian Unstable on my main machine a few days ago, and this time my Jupyter installation broke. So I updated my wrapper scripts for building Jupyter from source, to check out more recent versions of all the necessary components. Got the build done, started it up, and ... it seems my Jupyter has turned into JupyterLab. Yup, it has a new interface now. The file-manager display no longer seems to open things with a single click; that now only selects items, and you then have to perform an action (like open a notebook) from a right-click menu. And there is no “open in new tab/window” menu item; creating a new tab always happens when opening a notebook, while opening a subfolder always replaces the current tab contents. I used to be able to middle-click on a folder to open it in a new tab, but that option is now gone. There is an option in the right-click menu to “Copy Shareable Link”. When you do this on a notebook or folder and paste the result into the address bar, it opens the item in what I can only call “lab” mode. The window now has three panes, with the middle one an editor-type display, for viewing/editing notebook contents and other document content. The left-hand pane can show various things, selected by clicking one of the icons in its leftmost margin: it can show folder contents, or the table of contents of the current notebook, or a summary of open notebooks, running processes etc. And in the right-hand pane, there are various kinds of “tools” (for debugging, inspection etc) that only seem to appear when viewing notebook content. Ah, discovered how to control the visibility of this “tool” pane: it has two icons for selecting the two different categories of this it can display. But if you click the icon for the section that is already showing, the whole pane shrinks down to a narrow strip just showing the icons. Click again to expand the pane, of course. Further ah, same thing happens with the left-hand pane: click the icon for the section that’s already showing, and that pane too shrinks down. Hiding both the left- and right-hand panes brings you almost back to the old-style minimal-frills notebook/document display, except it only takes a click to bring one of those extras back. The middle pane has its own tab system, to let you have multiple documents open at once. You can drag its internal tabs around to tile them vertically or horizontally. And you can just drag a document to here from the folder display on the left to open it. Click on the document tab header, and that item opens in a separate browser window/tab. If nothing is open here it defaults to showing a “Launcher” tab, with icons for creating notebooks, opening terminal sessions, and creating other document types. The “lab” mode is activated by having an extra “/lab” part in the URL; if you remove this, it reverts to the old-style view of a single folder or notebook. Another thing that has changed is the way notebooks are saved. Previously, there was a menu option to “save and checkpoint” (with no option to do a manual save without checkpointing). And I found that if you tried to close the view of a modified notebook, it would ask to confirm you wanted to close the tab/window, but regardless of which you selected, the notebook would still be saved back to the file. Now that confirm-close trick no longer does saving; you have to explicitly select Save from the File menu, or hit CTRL/S. Checkpointing might still happen automatically as part of autosaving; I can’t find a menu option for explicitly creating a checkpoint, only for restoring from one. So anyway, a lot of intriguing new stuff in there to discover. If you like experimenting with code (as I do), Jupyter can be a great way to do it.

Superfile: A Modern Terminal File Manager for Linux and macOS
by Peter Reutemann 20 Jun '24

20 Jun '24

'Superfile is a modern terminal file manager that recently caught my attention; it’s not only easy to use but is very user-friendly compared to its alternatives, such as Ranger, MC, or nnn. It allows you to create files and directories, view (process, metadata, clipboard), provide a navigation pane, create multiple panels to work in two separate directories, support plugins, offer a variety of themes, and much more. The project is new, so there have been active updates every week, allowing you to see new features quickly. I’ve also been using it for a few days, and honestly, one key factor in using DE in Linux for me was its easy-to-use file manager, but with Superfile, there’s no need for that now.' -- source: https://linuxtldr.com/installing-superfile/ I've used mc in the past, being familiar with norton commander, but I might give Superfile a go in the future.

'"The KDE community announced the latest release of their popular desktop environment: Plasma 6.1," writes longtime Slashdot reader jrepin. From the announcement: While Plasma 6.0 was all about getting the migration to the underlying Qt 6 frameworks correct, Plasma 6.1 is where developers start implementing the features that will take you desktop to a new level. In this release, you will find features that go far beyond subtle changes to themes and tweaks to animations (although there is plenty of those too). Among some of the new features in this release you will find improved remote desktop support with a new built-in server, overhauled and streamlined desktop edit mode, restoration of open applications from the previous session on Wayland, synchronization of keyboard LED colors with the desktop accent color, making mouse cursor bigger and easier to find by shaking it, edge barriers (a sticky area for mouse cursor near the edges between screens), explicit sync support eliminates flickering and glitches for NVidia graphics card users on Wayland, and triple buffering support for smoother animations and screen rendering.' -- source: https://tech.slashdot.org/story/24/06/18/2050203 Cheers, Peter

Ransomware attackers quickly weaponize PHP vulnerability with 9.8 severity rating
by Peter Reutemann 17 Jun '24

17 Jun '24

'Ransomware criminals have quickly weaponized an easy-to-exploit vulnerability in the PHP programming language that executes malicious code on web servers, security researchers said. As of Thursday, Internet scans performed by security firm Censys had detected 1,000 servers infected by a ransomware strain known as TellYouThePass, down from 1,800 detected on Monday. The servers, primarily located in China, no longer display their usual content; instead, many list the site’s file directory, which shows all files have been given a .locked extension, indicating they have been encrypted. An accompanying ransom note demands roughly $6,500 in exchange for the decryption key. The vulnerability, tracked as CVE-2024-4577 and carrying a severity rating of 9.8 out of 10, stems from errors in the way PHP converts Unicode characters into ASCII. A feature built into Windows known as Best Fit allows attackers to use a technique known as argument injection to convert user-supplied input into characters that pass malicious commands to the main PHP application. Exploits allow attackers to bypass CVE-2012-1823, a critical code execution vulnerability patched in PHP in 2012. CVE-2024-4577 affects PHP only when it runs in a mode known as CGI, in which a web server parses HTTP requests and passes them to a PHP script for processing. Even when PHP isn’t set to CGI mode, however, the vulnerability may still be exploitable when PHP executables such as php.exe and php-cgi.exe are in directories that are accessible by the web server. This configuration is extremely rare, with the exception of the XAMPP platform, which uses it by default. An additional requirement appears to be that the Windows locale—used to personalize the OS to the local language of the user—must be set to either Chinese or Japanese.' -- source: https://arstechnica.com/security/2024/06/thousands-of-servers-infected-with… Cheers, Peter

Raspberry Pi is Now a Public Company
by Peter Reutemann 12 Jun '24

12 Jun '24

'Who would have thought that Raspberry Pi, the maker of the tiny, cheap, single-board computers, would become a public company? Yet, this is exactly what's happening: Raspberry Pi priced its IPO on the London Stock Exchange on Tuesday morning at $3.56 per share, valuing it at $689 million. Shortly after that, the company's shares jumped a nice 32% to $4.70. It means that Raspberry Pi could end up raising more than $200 million during its IPO process. Raspberry Pi has sold 60 million units since its inception. In 2023 alone, Raspberry Pi generated $266 million in revenue and $66 million in gross profit. Raspberry Pi Ltd, the public company, is the commercial subsidiary of the Raspberry Pi Foundation. The Foundation says it wants to make it easier for people to learn coding through a low-cost, programmable computer. It also remains the main shareholder of Raspberry Pi Ltd.' -- source: https://tech.slashdot.org/story/24/06/11/144251 Cheers, Peter

One-Line Patch For Intel Meteor Lake Yields Up To 72% Better Performance
by Peter Reutemann 11 Jun '24

11 Jun '24

'Michael Larabel reports via Phoronix: Covered last week on Phoronix was a new patch from Intel that with tuning to the P-State CPU frequency scaling driver was showing big wins for Intel Core Ultra "Meteor Lake" performance and power efficiency. I was curious with the Intel claims posted for a couple benchmarks and thus over the weekend set out to run many Intel Meteor Lake benchmarks on this one-line kernel patch... The results are great for boosting the Linux performance of Intel Core ultra laptops with as much as 72% better performance. [...] When looking at the CPU power consumption overall, for the wide variety of workloads tested it was just a slight uptick in power use and thus overall leading to slightly better power efficiency too. See all the data here. So this is quite a nice one-line Linux kernel patch for Meteor Lake and will hopefully be mainlined to the Linux kernel for Linux 6.11 if not squeezing it in as a "fix" for the current Linux 6.10 cycle. It's just too bad though that it took six months after launch for this tuned EPP value to be determined. Fresh benchmarks between Intel Core Ultra and AMD Ryzen on the latest Linux software will be coming up soon on Phoronix.' -- source: https://hardware.slashdot.org/story/24/06/10/2031256 Cheers, Peter

Nasty Linux Bug, CVE-2024-1086, is on the loose
by Peter Reutemann 05 Jun '24

05 Jun '24

'A few months back, CVE-2024-1086, a nasty use-after-free vulnerability in the Linux kernel's netfilter, was revealed. With a Common Vulnerability Scoring System (CVSS) score of 7.8, this bug, with the foundation for most Linux network firewall and Network Address Translation (NAT) programs, was a nasty little security hole. With it, Netfliter's table component could be exploited to achieve local privilege escalation. Worse still, you didn't need to be terribly clever to use it, so a local attacker could escalate privileges from a regular user to root in no time flat. Adding insult to injury, this vulnerability was present in pretty much all the major Linux distributions, including Debian, Fedora, Red Hat, and Ubuntu. In short, pretty much any Linux distribution using any kernel version between 5.14 and 6.6.14 could be hacked. Ouch! But, the fix has been in place since January 2024, when the flaw was patched. So, if we've been good little system administrators, we shouldn't have anything to worry about, right? Right!? Wrong. The US Cybersecurity and Infrastructure Security Agency (CISA) has flagged it and added it to the Known Exploited Vulnerabilities (KEV) catalog. It turns out that it's being actively exploited in the wild.' -- source: https://opensourcewatch.beehiiv.com/p/nasty-linux-bug-cve20241086-loose Cheers, Peter

'Today, Raspberry Pi introduced a new kit that adds AI functionality to the Raspberry Pi 5. ZDNet reports: The Raspberry Pi AI kit combines an M.2-format Hailo 8L AI accelerator with the Raspberry Pi M.2 HAT+ to create a powerful yet power-efficient solution. The Hailo-8L NPU (Neural Processing Unit) chip, capable of 13 trillion operations per second (TOPS), is built into an M.2 2242 form factor module that attaches to the M.2 HAT+. When connected to a Raspberry Pi 5 board running the latest Raspberry Pi OS, the NPU is automatically available for AI computing tasks. The AI module also has direct access to the Raspberry Pi's camera software stack and works with both first-party and third-party cameras. The NPU allows the Raspberry Pi 5 to perform AI tasks such as object and facial recognition, human pose analysis, and more. Using an NPU frees up the Raspberry Pi 5's CPU, allowing it to focus on other tasks, making your projects more efficient and powerful. The Raspberry Pi AI kit is also compatible with the Raspberry Pi Active Cooler, ensuring optimal performance without overheating. Additionally, you can purchase a clear protective layer to prevent damage to the board, giving you peace of mind while working on your projects. The AI kit is priced at $70. It's available from Raspberry Pi Approved Resellers, including PiHut, PiShop.us, and CanaKit. ' -- source: https://hardware.slashdot.org/story/24/06/04/2037238 Cheers, Peter

CentOS 7’s Final Countdown: 30 Days Left Until Support Ends
by Peter Reutemann 04 Jun '24

04 Jun '24

'In just 30 days, we’ll witness the end of an era for Linux with the cessation of support for CentOS 7—the last supported version of this once-dominant server operating system still receiving updates. Let’s take a quick look back at its journey. Ten years ago, on July 7, 2014, CentOS 7 was released as a fully compatible fork of Red Hat Enterprise Linux 7. Since its initial CentOS 2 version in 2004, the distribution has become extremely popular, establishing itself as the go-to server operating system over the last decade. After nine minor version updates, the latest being CentOS 7.9, in November 2020, Red Hat made a significant announcement. It marked the end of CentOS as a server operating system and transitioned it to CentOS Stream—a rolling release distro and upstream public development branch for Red Hat Enterprise Linux (RHEL). To complicate things further, CentOS 8, expected to receive updates until 2029, was prematurely retired at the end of December 2021. This leaves only CentOS 7 as the only version to complete its entire maintenance period, which ends in just 30 days on June 30, 2024. So, consider this as a final reminder if you’re still using CentOS 7 and haven’t yet migrated your system. Time is running out, and here are some alternative options to switch to a RHEL-compatible and supported replacement.' -- source: https://linuxiac.com/centos-7-has-30-days-left-until-support-ends/ Cheers, Peter

Fun With The du Command
by Lawrence D'Oliveiro 29 May '24

Looking at the space taken up by my copy of the Blender source code: ldo(a)theon:projects> du -ks blender 1444272 blender Most of that is in the commit history: ldo(a)theon:projects> du -ks blender/.git 1139640 blender/.git So how much isn’t? ldo(a)theon:projects> du -ks blender/.git blender 1139640 blender/.git 304632 blender Do you see what happened there? If you specify a directory, and then its containing directory on the same command, du will subtract the usage of the former from the latter. This gives you an easy way of determining the space taken up by a directory, not including particular subdirectories. This can be broken down even more: ldo(a)theon:projects> du -ks blender/.git blender/extern blender/intern blender/source blender 1139640 blender/.git 40536 blender/extern 15712 blender/intern 105188 blender/source 143196 blender Here, “extern” is various open-source libraries from other sources, that have been copied into the Blender source tree, while “intern” is code that originated from Blender itself, that has been organized into its own libraries. And as you can see, there is still a whole bunch left in other subdirectories. Does this work recursively? ldo(a)theon:projects> du -ks blender/.git blender/intern/cycles blender/intern blender 1139640 blender/.git 8880 blender/intern/cycles 6832 blender/intern 288920 blender Yes it does.

datamash - basic numeric, textual and statistical operations

Memory Sealing 'mseal' System Call Merged For Linux 6.10
by Peter Reutemann 27 May '24

27 May '24

'"Merged this Friday evening into the Linux 6.10 kernel is the new mseal() system call for memory sealing," reports Phoronix: The mseal system call was led by Jeff Xu of Google's Chrome team. The goal with memory sealing is to also protect the memory mapping itself against modification. The new mseal Linux documentation explains: "Modern CPUs support memory permissions such as RW and NX bits. The memory permission feature improves security stance on memory corruption bugs, i.e. the attacker can't just write to arbitrary memory and point the code to it, the memory has to be marked with X bit, or else an exception will happen. Memory sealing additionally protects the mapping itself against modifications. This is useful to mitigate memory corruption issues where a corrupted pointer is passed to a memory management system... Memory sealing can automatically be applied by the runtime loader to seal .text and .rodata pages and applications can additionally seal security-critical data at runtime. A similar feature already exists in the XNU kernel with the VM_FLAGS_PERMANENT flag and on OpenBSD with the mimmutable syscall." The mseal system call is designed to be used by the likes of the GNU C Library "glibc" while loading ELF executables to seal non-writable memory segments or by the Google Chrome web browser and other browsers for protecting security sensitive data structures.' -- source: https://linux.slashdot.org/story/24/05/26/2117251 Cheers, Peter

Ubuntu 24.04 Now Runs on the Nintendo Switch (Unofficially)
by Peter Reutemann 27 May '24

27 May '24

'"The fact it's possible at all is a credit to the ingenuity of the open-source community," writes the blog OMG Ubuntu: Switchroot is an open-source project that allows Android and Linux-based distros like Ubuntu to run on the Nintendo Switch — absolutely not something Nintendo approves of much less supports, endorses, or encourages, etc! I covered the loophole that made this possible back in 2018. Back then the NVIDIA Tegra X1-powered Nintendo Switch was still new and Linux support for much of the console's internal hardware in a formative state (a polite way to say 'not everything worked'). But as the popularity of Nintendo's handheld console ballooned (to understate it) so the 'alternative OS' Switch scene grew, and before long Linux support for Switch hardware was in full bloom... A number of Linux for Switchroot (L4S) distributions have since been released, designated as Linux for Tegra (L4T) builds. As these can boot from a microSD card it's even possible to dualboot the Switch OS with Linux, which is neat! Recently, a fresh set of L4T Ubuntu images were released based on the newest Ubuntu 24.04 LTS release. These builds work on all Switch versions, from the OG (exploit-friendly) unit through to newer, patched models (where a modchip is required)... I'm told all of the Nintendo Switch internal hardware now works under Linux, including Wi-Fi, Bluetooth, sleep mode, accelerated graphics, the official dock... Everything, basically. And despite being a 7 year old ARM device the performance is said to remain decent.

RISC-V Now Supports Rust In the Linux Kernel
by Peter Reutemann 24 May '24

24 May '24

'Michael Larabel reports via Phoronix: The latest RISC-V port updates have been merged for the in-development Linux 6.10 kernel. Most notable with today's RISC-V merge to Linux 6.10 is now supporting the Rust programming language within the Linux kernel. RISC-V joins the likes of x86_64, LoongArch, and ARM64 already supporting the use of the in-kernel Rust language support. The use of Rust within the mainline Linux kernel is still rather limited with just a few basic drivers so far and a lot of infrastructure work taking place, but there are a number of new drivers and other subsystem support on the horizon. RISC-V now supporting Rust within the Linux kernel will become more important moving forward. The RISC-V updates for Linux 6.10 also add byte/half-word compare-and-exchange, support for Zihintpause within hwprobe, a PR_RISCV_SET_ICACHE_FLUSH_CTX prctl(), and support for lockless lockrefs. More details on these RISC-V updates for Linux 6.10 via this Git merge. ' -- source: https://linux.slashdot.org/story/24/05/22/2337254 Cheers, Peter

A Root-Server at the Internet's Core Lost Touch With Its Peers. We Still Don't Know Why.
by Peter Reutemann 24 May '24

24 May '24

'A server maintained by Cogent Communications, one of the 13 root servers crucial to the Internet's domain name system, fell out of sync with its peers for over four days due to an unexplained glitch. This issue, which could have caused worldwide stability and security problems, was resolved on Wednesday. The root servers store cryptographic keys necessary for authenticating intermediate servers under the DNSSEC mechanism. Inconsistencies in these keys across the 13 servers could lead to an increased risk of attacks such as DNS cache poisoning. Engineers postponed planned updates to the .gov and .int domain name servers' DNSSEC to use ECDSA cryptographic keys until the situation stabilized. Cogent stated that it became aware of the issue on Tuesday and resolved it within 25 hours. ArsTechnica, which has a great writeup about the incident, adds: Initially, some people speculated that the depeering of Tata Communications, the c-root site outage, and the update errors to the c-root itself were all connected somehow. Given the vagueness of the statement, the relation of those events still isn't entirely clear.' -- source: https://it.slashdot.org/story/24/05/23/1745246 Cheers, Peter

Mozilla Says It's Concerned About Windows Recall
by Peter Reutemann 23 May '24

23 May '24

'Microsoft's Windows Recall feature is attracting controversy before even venturing out of preview. From a report: The principle is simple. Windows takes a snapshot of a user's active screen every few seconds and dumps it to disk. The user can then scroll through the snapshots and, when something is selected, the user is given options to interact with the content. Mozilla's Chief Product Officer, Steve Teixeira, told The Register: "Mozilla is concerned about Windows Recall. From a browser perspective, some data should be saved, and some shouldn't. Recall stores not just browser history, but also data that users type into the browser with only very coarse control over what gets stored. While the data is stored in encrypted format, this stored data represents a new vector of attack for cybercriminals and a new privacy worry for shared computers. "Microsoft is also once again playing gatekeeper and picking which browsers get to win and lose on Windows -- favoring, of course, Microsoft Edge. Microsoft's Edge allows users to block specific websites and private browsing activity from being seen by Recall. Other Chromium-based browsers can filter out private browsing activity but lose the ability to block sensitive websites (such as financial sites) from Recall. "Right now, there's no documentation on how a non-Chromium based, third-party browser, such as Firefox, can protect user privacy from Recall. Microsoft did not engage our cooperation on Recall, but we would have loved for that to be the case, which would have enabled us to partner on giving users true agency over their privacy, regardless of the browser they choose."' -- source: https://tech.slashdot.org/story/24/05/22/1939244 Cheers, Peter

Linux 6.10 Honors One Last Request By Hans Reiser
by Peter Reutemann 22 May '24

22 May '24

'Phoronix: ReiserFS lead developer and convicted murderer Hans Reiser a few months back wrote letters to be made public apologizing for his social mistakes and other commentary. In his written communications he also made a last request for ReiserFS in the Linux kernel: "Assuming that the decision is to remove [ReiserFS] V3 from the kernel, I have just one request: that for one last release the README be edited to add Mikhail Gilula, Konstantin Shvachko, and Anatoly Pinchuk to the credits, and to delete anything in there I might have said about why they were not credited. It is time to let go." Hans credits his improved social and communication skills learned in prison among other details shared in the public letters. Per the indirect request by Hans Reiser, SUSE's Jan Kara has now altered the ReiserFS README file with the changes going in today to the Linux 6.10 kernel. The negative language was removed and instead acknowledging their contributions.' -- source: https://linux.slashdot.org/story/24/05/21/217228 Cheers, Peter

New Windows AI feature records everything you’ve done on your PC
by Peter Reutemann 22 May '24

22 May '24

'At a Build conference event on Monday, Microsoft revealed a new AI-powered feature called "Recall" for Copilot+ PCs that will allow Windows 11 users to search and retrieve their past activities on their PC. To make it work, Recall records everything users do on their PC, including activities in apps, communications in live meetings, and websites visited for research. Despite encryption and local storage, the new feature raises privacy concerns for certain Windows users. "Recall uses Copilot+ PC advanced processing capabilities to take images of your active screen every few seconds," Microsoft says on its website. "The snapshots are encrypted and saved on your PC’s hard drive. You can use Recall to locate the content you have viewed on your PC using search or on a timeline bar that allows you to scroll through your snapshots." By performing a Recall action, users can access a snapshot from a specific time period, providing context for the event or moment they are searching for. It also allows users to search through teleconference meetings they've participated in and videos watched using an AI-powered feature that transcribes and translates speech. At first glance, the Recall feature seems like it may set the stage for potential gross violations of user privacy. Despite reassurances from Microsoft, that impression persists for second and third glances as well. For example, someone with access to your Windows account could potentially use Recall to see everything you've been doing recently on your PC, which might extend beyond the embarrassing implications of pornography viewing and actually threaten the lives of journalists or perceived enemies of the state. Despite the privacy concerns, Microsoft says that the Recall index remains local and private on-device, encrypted in a way that is linked to a particular user's account. "Recall screenshots are only linked to a specific user profile and Recall does not share them with other users, make them available for Microsoft to view, or use them for targeting advertisements. Screenshots are only available to the person whose profile was used to sign in to the device," Microsoft says. Users can pause, stop, or delete captured content and can exclude specific apps or websites. Recall won't take snapshots of InPrivate web browsing sessions in Microsoft Edge or DRM-protected content. However, Recall won't actively hide sensitive information like passwords and financial account numbers that appear on-screen.' -- source: https://arstechnica.com/gadgets/2024/05/microsofts-new-recall-feature-will-… Talking about intrusive OS... I wonder whether there will be an ad-supported, cheap version of Windows in the future where the user can't turn Recall off, giving Microsoft a large pool of free training data... Cheers, Peter

Ubuntu 24.10 to Default to Wayland for NVIDIA Users
by Peter Reutemann 20 May '24

20 May '24

'OMG Ubuntu: Ubuntu first switched to using Wayland as its default display server in 2017 before reverting the following year. It tried again in 2021 and has stuck with it since. But while Wayland is what most of us now log into after installing Ubuntu, anyone doing so on a PC or laptop with an NVIDIA graphics card present instead logs into an Xorg/X11 session. This is because NVIDIA's proprietary graphics drivers (which many, especially gamers, opt for to get the best performance, access to full hardware capabilities, etc) have not supported Wayland as well as as they could've. Past tense as, thankfully, things have changed in the past few years. NVIDIA's warmed up to Wayland (partly as it has no choice given that Wayland is now standard and a 'maybe one day' solution, and partly because it wants to: opportunities/benefits/security). With the NVIDIA + Wayland sitch' now in a better state than before — but not perfect — Canonical's engineers say they feel confident enough in the experience to make the Ubuntu Wayland session default for NVIDIA graphics card users in Ubuntu 24.10.' -- source: https://news.slashdot.org/story/24/05/20/013218 Cheers, Peter

Linux Foundation Announces Launch of 'High Performance Software Foundation'
by Peter Reutemann 20 May '24

20 May '24

'This week the nonprofit Linux Foundation announced the launch of the High Performance Software Foundation, which "aims to build, promote, and advance a portable core software stack for high performance computing" (or HPC) by "increasing adoption, lowering barriers to contribution, and supporting development efforts." It promises initiatives focused on "continuously built, turnkey software stacks," as well as other initiatives including architecture support and performance regression testing. Its first open source technical projects are: - Spack: the HPC package manager. - Kokkos: a performance-portable programming model for writing modern C++ applications in a hardware-agnostic way. - Viskores (formerly VTK-m): a toolkit of scientific visualization algorithms for accelerator architectures. - HPCToolkit: performance measurement and analysis tools for computers ranging from desktop systems to GPU-accelerated supercomputers. - Apptainer: Formerly known as Singularity, Apptainer is a Linux Foundation project providing a high performance, full featured HPC and computing optimized container subsystem. - E4S: a curated, hardened distribution of scientific software packages. As use of HPC becomes ubiquitous in scientific computing and digital engineering, and AI use cases multiply, more and more data centers deploy GPUs and other compute accelerators. The High Performance Software Foundation will provide a neutral space for pivotal projects in the high performance computing ecosystem, enabling industry, academia, and government entities to collaborate on the scientific software. The High Performance Software Foundation benefits from strong support across the HPC landscape, including Premier Members Amazon Web Services (AWS), Hewlett Packard Enterprise, Lawrence Livermore National Laboratory, and Sandia National Laboratories; General Members AMD, Argonne National Laboratory, Intel, Kitware, Los Alamos National Laboratory, NVIDIA, and Oak Ridge National Laboratory; and Associate Members University of Maryland, University of Oregon, and Centre for Development of Advanced Computing. In a statement, an AMD vice president said that by joining "we are using our collective hardware and software expertise to help develop a portable, open-source software stack for high-performance computing across industry, academia, and government." And an AWS executive said the high-performance computing community "has a long history of innovation being driven by open source projects. AWS is thrilled to join the High Performance Software Foundation to build on this work. In particular, AWS has been deeply involved in contributing upstream to Spack, and we're looking forward to working with the HPSF to sustain and accelerate the growth of key HPC projects so everyone can benefit." The new foundation will "set up a technical advisory committee to manage working groups tackling a variety of HPC topics," according to the announcement, following a governance model based on the Cloud Native Computing Foundation.' -- source: https://tech.slashdot.org/story/24/05/19/2234254 Cheers, Peter

Why a 'Frozen' Distribution Linux Kernel Isn't the Safest Choice for Security
by Peter Reutemann 20 May '24

20 May '24

'Jeremy Allison — Sam (Slashdot reader #8,157) is a Distinguished Engineer at Rocky Linux creator CIQ. This week he published a blog post responding to promises of Linux distros "carefully selecting only the most polished and pristine open source patches from the raw upstream open source Linux kernel in order to create the secure distribution kernel you depend on in your business." But do carefully curated software patches (applied to a known "frozen" Linux kernel) really bring greater security? "After a lot of hard work and data analysis by my CIQ kernel engineering colleagues Ronnie Sahlberg and Jonathan Maple, we finally have an answer to this question. It's no." The data shows that "frozen" vendor Linux kernels, created by branching off a release point and then using a team of engineers to select specific patches to back-port to that branch, are buggier than the upstream "stable" Linux kernel created by Greg Kroah-Hartman. How can this be? If you want the full details the link to the white paper is here. But the results of the analysis couldn't be clearer. - A "frozen" vendor kernel is an insecure kernel. A vendor kernel released later in the release schedule is doubly so. - The number of known bugs in a "frozen" vendor kernel grows over time. The growth in the number of bugs even accelerates over time. - There are too many open bugs in these kernels for it to be feasible to analyze or even classify them.... [T]hinking that you're making a more secure choice by using a "frozen" vendor kernel isn't a luxury we can still afford to believe. As Greg Kroah-Hartman explicitly said in his talk "Demystifying the Linux Kernel Security Process": "If you are not using the latest stable / longterm kernel, your system is insecure." CIQ describes its report as "a count of all the known bugs from an upstream kernel that were introduced, but never fixed in RHEL 8." For the most recent RHEL 8 kernels, at the time of writing, these counts are: RHEL 8.6 : 5034 RHEL 8.7 : 4767 RHEL 8.8 : 4594 In RHEL 8.8 we have a total of 4594 known bugs with fixes that exist upstream, but for which known fixes have not been back-ported to RHEL 8.8. The situation is worse for RHEL 8.6 and RHEL 8.7 as they cut off back-porting earlier than RHEL 8.8 but of course that did not prevent new bugs from being discovered and fixed upstream.... This whitepaper is not meant as a criticism of the engineers working at any Linux vendors who are dedicated to producing high quality work in their products on behalf of their customers. This problem is extremely difficult to solve. We know this is an open secret amongst many in the industry and would like to put concrete numbers describing the problem to encourage discussion. Our hope is for Linux vendors and the community as a whole to rally behind the kernel.org stable kernels as the best long term supported solution. As engineers, we would prefer this to allow us to spend more time fixing customer specific bugs and submitting feature improvements upstream, rather than the endless grind of backporting upstream changes into vendor kernels, a practice which can introduce more bugs than it fixes. ZDNet calls it "an open secret in the Linux community." It's not enough to use a long-term support release. You must use the most up-to-date release to be as secure as possible. Unfortunately, almost no one does that. Nevertheless, as Google Linux kernel engineer Kees Cook explained, "So what is a vendor to do? The answer is simple: if painful: Continuously update to the latest kernel release, either major or stable." Why? As Kroah-Hartman explained, "Any bug has the potential of being a security issue at the kernel level...." Although [CIQ's] programmers examined RHEL 8.8 specifically, this is a general problem. They would have found the same results if they had examined SUSE, Ubuntu, or Debian Linux. Rolling-release Linux distros such as Arch, Gentoo, and OpenSUSE Tumbleweed constantly release the latest updates, but they're not used in businesses.' -- source: https://linux.slashdot.org/story/24/05/19/0030248 Cheers, Peter

Google patches its fifth zero-day vulnerability of the year in Chrome
by Peter Reutemann 13 May '24

13 May '24

'Google has updated its Chrome browser to patch a high-severity zero-day vulnerability that allows attackers to execute malicious code on end user devices. The fix marks the fifth time this year the company has updated the browser to protect users from an existing malicious exploit. The vulnerability, tracked as CVE-2024-4671, is a “use after free,” a class of bug that occurs in C-based programming languages. In these languages, developers must allocate memory space needed to run certain applications or operations. They do this by using “pointers” that store the memory addresses where the required data will reside. Because this space is finite, memory locations should be deallocated once the application or operation no longer needs it. Use-after-free bugs occur when the app or process fails to clear the pointer after freeing the memory location. In some cases, the pointer to the freed memory is used again and points to a new memory location storing malicious shellcode planted by an attacker’s exploit, a condition that will result in the execution of this code. On Thursday, Google said an anonymous source notified it of the vulnerability. The vulnerability carries a severity rating of 8.8 out of 10. In response, Google said, it would be releasing versions 124.0.6367.201/.202 for macOS and Windows and 124.0.6367.201 for Linux in subsequent days. “Google is aware that an exploit for CVE-2024-4671 exists in the wild,” the company said.' -- source: https://arstechnica.com/security/2024/05/google-patches-its-fifth-zero-day-… Cheers, Peter

Linux Kernel 6.9 Officially Released
by Peter Reutemann 13 May '24

13 May '24

'"6.9 is now out," Linus Torvalds posted on the Linux kernel mailing list, "and last week has looked quite stable (and the whole release has felt pretty normal)." Phoronix writes that Linux 6.9 "has a number of exciting features and improvements for those habitually updating to the newest version." And Slashdot reader prisoninmate shared this report from 9to5Linux: Highlights of Linux kernel 6.9 include Rust support on AArch64 (ARM64) architectures, support for the Intel FRED (Flexible Return and Event Delivery) mechanism for improved low-level event delivery, support for AMD SNP (Secure Nested Paging) guests, and a new dm-vdo (virtual data optimizer) target in device mapper for inline deduplication, compression, zero-block elimination, and thin provisioning. Linux kernel 6.9 also supports the Named Address Spaces feature in GCC (GNU Compiler Collection) that allows the compiler to better optimize per-CPU data access, adds initial support for FUSE passthrough to allow the kernel to serve files from a user-space FUSE server directly, adds support for the Energy Model to be updated dynamically at run time, and introduces a new LPA2 mode for ARM 64-bit processors... Linux kernel 6.9 will be a short-lived branch supported for only a couple of months. It will be succeeded by Linux kernel 6.10, whose merge window has now been officially opened by Linus Torvalds. Linux kernel 6.10 is expected to be released in mid or late September 2024. "Rust language has been updated to version 1.76.0 in Linux 6.9," according to the article. And Linus Torvalds shared one more details on the Linux kernel mailing list. "I now have a more powerful arm64 machine (thanks to Ampere), so the last week I've been doing almost as many arm64 builds as I have x86-64, and that should obviously continue during the upcoming merge window too."' -- source: https://linux.slashdot.org/story/24/05/12/2212235 Cheers, Peter

Fedora Asahi Remix 40 is another big step forward for Linux on Apple Silicon Mac
by Peter Reutemann 10 May '24

10 May '24

'Asahi Linux, the project that aims to bring desktop Linux to Apple hardware with Apple silicon—the M series of chips—is out with Fedora Asahi Remix 40. More hardware features of Apple devices are supported, the Fedora Linux 40-based distro ships with KDE's new Plasma 6 desktop, and untold numbers of bugs are squashed, to be replaced with reams more. Fedora Asahi Remix is a "fully integrated distro," according to the Asahi team, and you can "expect a solid and high-quality experience without any unwanted surprises." It supports all the M1 and M2 devices in the MacBook, Mac Mini, Mac Studio, and iMac lines. It's OpenGL 4.6 and OpenGL ES 3.2 certified, and comes with "the best Linux laptop audio you've ever heard." So, should you install it on your Mac? Keep scrolling down Asahi's release page and check the "Device support" section. Still missing from most M-series Apple devices are support for Thunderbolt and USB4, built-in microphones, and Touch ID, as well as USB-C display support. Speakers are not supported on the iMac. And HDMI audio is in rough shape, being able to "break audio on the system completely." Still, for someone using an Apple laptop primarily as a portable device, or simply connecting to a monitor with less modern all-in-one cables, there is a desktop awaiting. Installing it is a single cURL command.' -- source: https://arstechnica.com/gadgets/2024/05/fedora-asahi-remix-40-is-another-bi… Cheers, Peter

Raspberry Pis get a built-in remote access tool: Raspberry Pi Connect
by Peter Reutemann 08 May '24

08 May '24

'One Raspberry Pi often leads to another. Soon enough, you're running out of spots in your free RealVNC account for your tiny boards and "real" computers. Even if you go the hardened route of SSH or an X connection, you have to keep track of where they all are. All of this is not the easiest thing to tackle if you're new to single-board computers or just eager to get started. Enter Raspberry Pi Connect, a new built-in way to access a Rasbperry Pi from nearly anywhere you can open a browser, whether to control yourself or provide remote assistance. On a Raspberry Pi 4, 5, or Pi 400 kit, you install Pi connect with a single terminal line, reboot the Pi, and then click a new tray icon to connect the Pi to a Raspberry Pi ID (and then enable two-factor authentication, of course). >From then on, visiting connect.raspberrypi.com gives you an encrypted connection to your desktop. It's a direct connection if possible, and if not, it runs through relay servers in London, encrypting it with DTLS and keeping only the metadata needed for the service to work. The Pi will show a notification in its tray that somebody has connected, and you can manage screen sharing from there. The Pi's docs site has a lot more on the particulars. Connect works only on 64-bit systems running the Bookworm version of Pi OS with a Wayland window server. Connect was created partly due to Pi's transition to Wayland from X, which offered its own remote desktop option. According to the Pi firm, the service runs on a peer-to-peer WebRTC connection, similar to that of Zoom, Slack, Teams, and other video-sharing services. The whole service is in beta at the moment, and the company says it's not quite sure how much traffic to expect through its relay servers.' -- source: https://arstechnica.com/gadgets/2024/05/raspberry-pis-get-a-built-in-remote… Cheers, Peter

Novel attack against virtually all VPN apps neuters their entire purpose
by Peter Reutemann 07 May '24

07 May '24

'Researchers have devised an attack against nearly all virtual private network applications that forces them to send and receive some or all traffic outside of the encrypted tunnel designed to protect it from snooping or tampering. TunnelVision, as the researchers have named their attack, largely negates the entire purpose and selling point of VPNs, which is to encapsulate incoming and outgoing Internet traffic in an encrypted tunnel and to cloak the user’s IP address. The researchers believe it affects all VPN applications when they’re connected to a hostile network and that there are no ways to prevent such attacks except when the user's VPN runs on Linux or Android. They also said their attack technique may have been possible since 2002 and may already have been discovered and used in the wild since then. The effect of TunnelVision is “the victim's traffic is now decloaked and being routed through the attacker directly,” a video demonstration explained. “The attacker can read, drop or modify the leaked traffic and the victim maintains their connection to both the VPN and the Internet.” The attack works by manipulating the DHCP server that allocates IP addresses to devices trying to connect to the local network. A setting known as option 121 allows the DHCP server to override default routing rules that send VPN traffic through a local IP address that initiates the encrypted tunnel. By using option 121 to route VPN traffic through the DHCP server, the attack diverts the data to the DHCP server itself.' -- source: https://arstechnica.com/security/2024/05/novel-attack-against-virtually-all… Cheers, Peter

Kernel Modules Are Now Compressed

Not sure if this is mentioned in any release notes anywhere, but the .ko files (loadable kernel modules) that would live in /lib/modules/«kernel version»/ are now .ko.xz files. Looks like this happened starting with the 6.6 kernel. I discovered this a few minutes ago, while trying to count how many .ko files came with my 6.7.9 Debian kernel, with find /lib/modules/$(uname -r) -name \*.ko | wc -l and was surprised to see that the answer was 0. A suitably adjusted command find /lib/modules/$(uname -r) -name \*.ko\* | wc -l returns 4165

Yet Another New systemd Feature
by Lawrence D'Oliveiro 06 May '24

06 May '24

Lennart Poettering wants to get rid of sudo now, and replace it with a new systemd feature called “run0” <https://itwire.com/business-it-news/open-source/poettering-announces-tool-i…>. It is hard to write code that runs setuid, and sudo has had quite a few security vulnerabilities over the years. So Poettering’s idea is to replace the setuid executable with another use of the existing PolicyKit system. Interesting that Poettering thinks we should get rid of the whole idea of setuid altogether. AT&T actually got a patent on the concept, back in the early days of Unix. Other OSes had the concept of privileged code, but what made setuid different is that any user can set this mode on any executable they create, and when other users run this executable (if they are allowed to), they temporarily get the permissions of the owning user. On Linux, this concept was always constrained a bit: I think it only works on compiled machine-code executables, not on interpreted scripts.

Maximum-Severity GitLab Flaw Allowing Account Hijacking Under Active Exploitation
by Peter Reutemann 03 May '24

03 May '24

'Dan Goodin reports via Ars Technica: A maximum severity vulnerability that allows hackers to hijack GitLab accounts with no user interaction required is now under active exploitation, federal government officials warned as data showed that thousands of users had yet to install a patch released in January. A change GitLab implemented in May 2023 made it possible for users to initiate password changes through links sent to secondary email addresses. The move was designed to permit resets when users didn't have access to the email address used to establish the account. In January, GitLab disclosed that the feature allowed attackers to send reset emails to accounts they controlled and from there click on the embedded link and take over the account. While exploits required no user interaction, hijackings worked only against accounts that weren't configured to use multi-factor authentication. Even with MFA, accounts remained vulnerable to password resets. The vulnerability, tracked as CVE-2023-7028, carries a severity rating of 10 out of a possible 10. The vulnerability, classified as an improper access control flaw, could pose a grave threat. GitLab software typically has access to multiple development environments belonging to users. With the ability to access them and surreptitiously introduce changes, attackers could sabotage projects or plant backdoors that could infect anyone using software built in the compromised environment. An example of a similar supply chain attack is the one that hit SolarWinds in 2021, infecting more than 18,000 of its customers. Other recent examples of supply chain attacks are here, here, and here. These sorts of attacks are powerful. By hacking a single, carefully selected target, attackers gain the means to infect thousands of downstream users, often without requiring them to take any action at all. According to Internet scans performed by security organization Shadowserver, more than 2,100 IP addresses showed they were hosting one or more vulnerable GitLab instances. In order to protect your system, you should enable MFA and install the latest patch. "GitLab users should also remember that patching does nothing to secure systems that have already been breached through exploits," notes Goodin.' -- source: https://it.slashdot.org/story/24/05/02/1934220 Cheers, Peter -- My Open Source Blog - http://open.fracpete.org

I Have No Luck With Keyboards ...
by Lawrence D'Oliveiro 01 May '24

01 May '24

Yesterday I decided that my heavily-used clicky mechanical keyboard (a Das Keyboard 4) had accumulated far too much grime, and it was time to take the risk of cleaning it. In the past, every time I’ve tried cleaning a keyboard, it has never worked right afterwards. I’m a software guy, not a hardware guy. I found the keys quite easy to pry off. A light amount of leverage with a small screwdriver was helpful when space was tight, but once I’d cleared sufficient room around a key, I could pull it off just with my fingers. Even the wider keys were not hard. I found some warnings online against removing these, because of the trickiness of their extra stabilization mechanisms. But these were actually quite simple: a steel spring with its ends poked through two tiny brackets (removable, but best left in place) at each end of the key. It took a bit of pressure with the screwdriver to bend one end of the spring far enough to take it out of the hole, but it snapped immediately back to its original shape after I had taken the key out, so I saw no problem putting things back afterwards. The space bar was even simpler: just two additional support posts at the ends, in addition to the usual post (common to all the keys) that held the actual switch in the middle. After I had got all the keys off, the grime on the keyboard itself was a wonder to behold (I’ll spare you the details). I tried to use a bunched-up corner of a wet cloth, and even a vacuum cleaner with the smallest nozzle (again heeding warnings online against compressed air), and I was able to remove maybe half the accumulation of deposits, not much more. I figured that was good enough. Of course, in the process, I likely got some water into two slots that were exposed after I removed the keys. There was a recommendation online to leave things to dry for at least 6 hours. Call me impatient; I left it for just 5. Afterwards, I plugged it in, without the key caps, and tried a few keys, and was gratified to find they still worked. After that, I put back all the keys, now nice and clean and dry. Even the ones with those extra springs went back with only a slight amount of fiddling to re-engage with those brackets on the keys. And afterwards, the keyboard still worked. I left it plugged in, and went to do something else. Half an hour later, I came back to my computer ... and the keyboard was dead. Not a single response from any key. Put it back in the heater cupboard and left it overnight. No change this morning: still dead. So I feel very sad. I thought I had broken my keyboard jinx. But it’s currently zero for three. I have some other keyboards, of course, including a colourful oddity I bought from Dick Smith (whose layout leaves out the right-hand super/windows key), and a Kensington “washable” (dare I risk it?), with the pipe/backslash key in a different position. But I had grown accustomed to the volume control knob and other niceties of the Das Keyboard. Looking back through my records, I was surprised to discover I had bought it about ten years ago, from Mighty Ape. So I suppose it’s had a good run. But it seems nobody in NZ sells the things any more. So currently I mourn, and I also look for alternatives ...

Hackers try to exploit WordPress plugin vulnerability that’s as severe as it gets
by Peter Reutemann 29 Apr '24

29 Apr '24

'Hackers are assailing websites using a prominent WordPress plugin with millions of attempts to exploit a high-severity vulnerability that allows complete takeover, researchers said. The vulnerability resides in WordPress Automatic, a plugin with more than 38,000 paying customers. Websites running the WordPress content management system use it to incorporate content from other sites. Researchers from security firm Patchstack disclosed last month that WP Automatic versions 3.92.0 and below had a vulnerability with a severity rating of 9.9 out of a possible 10. The plugin developer, ValvePress, silently published a patch, which is available in versions 3.92.1 and beyond. Researchers have classified the flaw, tracked as CVE-2024-27956, as a SQL injection, a class of vulnerability that stems from a failure by a web application to query backend databases properly. SQL syntax uses apostrophes to indicate the beginning and end of a data string. By entering strings with specially positioned apostrophes into vulnerable website fields, attackers can execute code that performs various sensitive actions, including returning confidential data, giving administrative system privileges, or subverting how the web app works.' -- source: https://arstechnica.com/security/2024/04/hackers-make-millions-of-attempts-… Cheers, Peter

Alternative To Microsoft Access
by Lawrence D'Oliveiro 27 Apr '24

27 Apr '24

If anybody asks about an alternative to Microsoft Access, I think SQLite used in combination with LibreOffice will give you a lot of functionality, including comprehensive SQL support and scalability to much larger databases. Of course you can use other backends, like MariaDB/MySQL, as well. SQLite just makes it easy to have an actual database file that you can copy/move about the place, without having to do database dumps/restores. If you don’t need multiuser support, it is very convenient. I notice that libreoffice-base is now a separate package under Debian (and I suppose its derivatives as well), no longer included in the “base” (heh) LibreOffice package. Make sure to install this, along with libsqliteodbc. Now, say you have an existing SQLite3 database that you want to access from LibreOffice. Suppose it is in the file /home/ldo/hack/lo_try/test.db. In order for databases to be accessible via ODBC, they need to have entries in your ~/.odbc.ini file. This is just a text file, in the good old .ini tradition. The format for entries is very simple, e.g.: [test-db] Description=Test database for LibreOffice Base Driver=SQLite3 Database=/home/ldo/hack/lo_try/test.db Now, when you launch the LibreOffice Base database wizard, you have options to “create a new database”, “open an existing database file”, or “connect to an existing database”. Choose that last one “connect to an existing database”. The popup menu shows the available back-end drivers: choose “ODBC”. Now, when you click “Next”, there should be a text field with a “Browse...” button; clicking this should show the names of entries in your ~/.odbc.ini file, e.g. “test-db” if you used the name in my example above. Select this, and click “Finish”. Next you will be prompted for a name to save the “database file”. This is just the LibreOffice Base document that contains the settings for connecting to the actual database: LibreOffice doesn’t know or care where the database back-end keeps the actual data. After having named the LibreOffice database file, you should see the main LibreOffice Base window. In the lower half, under “Tables”, you should see a list of the tables from the database file. You can double-click a table name to see a quick list of all its records. That’s as far as I’ve got. I see a “Design View”, “Form Wizards”, and “Report Wizards”, and all kinds of other fun stuff. Should be great for building simple database applications, with a minimum of programming.

Ex WH Cyber Policy Director: Microsoft Is A Threat To US National Security
by Lawrence D'Oliveiro 23 Apr '24

23 Apr '24

Microsoft has become so dominant a supplier to the US Government that it cannot be effectively called to account on its repeated security lapses <https://www.theregister.com/2024/04/21/microsoft_national_security_risk/>. Even something as basic as event logging (which would have helped track exposure to things like the SolarWinds breach) was an extra-cost service that Microsoft customers had to pay for. Microsoft is squeezing a lot of profit out of those customers, and it feels no need to let up.

Ubuntu 24.04 Yields a 20% Performance Advantage Over Windows 11 On Ryzen 7 Framework Laptop
by Peter Reutemann 19 Apr '24

19 Apr '24

'Michael Larabel reports via Phoronix: With the Framework 16 laptop one of the performance pieces I've been meaning to carry out has been seeing out Linux performs against Microsoft Windows 11 for this AMD Ryzen 7 7840HS powered modular/upgradeable laptop. Recently getting around to it in my benchmarking queue, I also compared the performance of Ubuntu 23.10 to the near final Ubuntu 24.04 LTS on this laptop up against a fully-updated Microsoft Windows 11 installation. The Framework 16 review unit as a reminder was configured with the 8-core / 16-thread AMD Ryzen 7 7840HS Zen 4 SoC with Radeon RX 7700S graphics, a 512GB SN810 NVMe SSD, MediaTek MT7922 WiFi, and a 2560 x 1600 display. In the few months of testing out the Framework 16 predominantly under Linux it's been working out very well. With also having a Windows 11 partition as shipped by Framework, after updating that install it made for an interesting comparison against the Ubuntu 23.10 and Ubuntu 24.04 performance. The same Framework 16 AMD laptop was used throughout all of the testing for looking at the out-of-the-box performance across Microsoft Windows 11, Ubuntu 23.10, and the near-final state of Ubuntu 24.04. [...] Out of 101 benchmarks carried out on all three operating systems with the Framework 16 laptop, Ubuntu 24.04 was the fastest in 67% of those tests, the prior Ubuntu 23.10 led in 22% (typically with slim margins to 24.04), and then Microsoft Windows 11 was the front-runner just 10% of the time... If taking the geomean of all 101 benchmark results, Ubuntu 23.10 was 16% faster than Microsoft Windows 11 while Ubuntu 24.04 enhanced the Ubuntu Linux performance by 3% to yield a 20% advantage over Windows 11 on this AMD Ryzen 7 7840HS laptop. Ubuntu 24.04 is looking very good in the performance department and will see its stable release next week. ' -- source: https://hardware.slashdot.org/story/24/04/18/2321230 Cheers, Peter

FFmpeg 7.0 “Dijkstra”: Best New Features
by Peter Reutemann 19 Apr '24

19 Apr '24

'One of the major updates in FFmpeg 7.0 is the parallel execution of operations for unpacking/packing media containers, decoding, encoding, and applying filters using the ffmpeg command line utility. This feature allows for the simultaneous execution of multiple tasks, resulting in a significant improvement in performance and efficiency, particularly when working with large-scale multimedia projects. Another notable addition is the support for encoding and decoding video in MPEG-5 format (EVC – Essential Video Coding) using the external library libxevd. This new format provides high efficiency transmission and storage of all screen resolutions, supports video with an extended dynamic range (HDR), and panoramic video in 360-degree mode. In addition, FFmpeg 7.0 has added unpackers and packers of media containers (demuxer/muxer) for the QOA (Quite OK Audio) format, which is used for transmitting audio with loss of quality. QOA decoding is claimed to be three times faster than Ogg-Vorbis while achieving higher quality and compression levels compared to ADPCM. The new version also includes unpackers and packers of media containers (demuxer/muxer) for the IAMF (Immersive Audio Model and Format) format, which defines a container for distributing surround sound. The format provides for the transmission of additional information necessary for the operation of sound stage reconstruction and sound mixing algorithms, and takes into account the propagation of sound signals in three-dimensional space to recreate sound as close to natural as possible. An experimental decoder for the VVC (Versatile Video Coding) format, also known as the H.266 video compression standard, has been added in FFmpeg 7.0. This new format provides high efficiency transmission and storage of all screen resolutions, supports video with an extended dynamic range (HDR), and panoramic video in 360-degree mode. The ffplay utility has added support for hardware acceleration of decoding using the Vulkan and libplacebo APIs, and the ability to use API D3D12VA (Direct 3D 12 Video Encoding) for hardware acceleration of decoding of H264, HEVC, VP9, AV1, MPEG-2 and VC1 formats has been implemented. [...] Remember: This version is NOT backward compatible. That means, many CLI options and API are removed which are long deprecated. So use caution before upgrading to version 7.0.' -- source: https://www.debugpoint.com/ffmpeg-7-0-features/ Cheers, Peter -- My Open Source Blog - http://open.fracpete.org

High Priority PuTTY Vulnerability Threatens Server Access Security
by Peter Reutemann 19 Apr '24

19 Apr '24

'A critical security vulnerability in PuTTY, a very popular software for secure terminal access to remote servers, has been discovered. This vulnerability could put the private keys of many users at risk. Cataloged as CVE-2024-31497, the vulnerability affects PuTTY version numbers between 0.68 and 0.80. So, if you have been using PuTTY during this time, it is important to be aware of what this means for your data security. Fabian Bäumer and Marcus Brinkmann of the Ruhr University Bochum found the vulnerability. It concerns how PuTTY forms signatures from the ECDSA private keys on the NIST P521 curve. The vulnerability with PuTTY is that it creates a component of the signature called ‘nonce’ during the generation process. This randomly generated number can be used once in a cryptographic communication, thus ensuring that old communications cannot be reused in replay attacks. However, PuTTY used a deterministic method to generate nonces due to the lack of a high-quality random number generator in early Windows systems. This deterministic method was biased for the P521 curve, which made the private key recovery possible. Simply put, an attacker who gets hold of multiple signed messages can potentially recover your private key due to a specific bias in the signature creation process. This would allow them to forge signatures and access any servers where you’ve used this key.' -- source: https://linuxiac.com/high-priority-putty-vulnerability-found/ Cheers, Peter -- My Open Source Blog - http://open.fracpete.org

Packages With “t64” On The Ends Of Their Names
by Lawrence D'Oliveiro 15 Apr '24

15 Apr '24

Lately, in Debian Unstable, I have noticed package names starting to appear with “t64” on the ends. No doubt this will percolate through to Debian derivatives as well. I wondered what this was about, and found this forum thread <https://www.antixforum.com/forums/topic/t64-at-the-end-of-a-package-title/>. This has to do with the “year-2038” problem, which should only affect 32-bit systems anyway. But it seems some people are sufficiently concerned about this to ensure that their code will build with a 64-bit size for time_t (the POSIX type for holding the number of seconds since 1st January 1970), even on 32-bit systems. This is controlled at build time by setting the _TIME_BITS symbol to the value 64. There is a file /usr/include/features-time64.h (present if you have the libc6-dev package installed) that does the necessary setup of other time-related API calls based on this. On 64-bit systems (which is what most of us would be running by now), there would be absolutely no difference in the code with this setting. So the change in package name is I think only to maintain compatibility with 32-bit architectures.

“Highly capable” hackers root corporate networks by exploiting firewall 0-day
by Peter Reutemann 15 Apr '24

15 Apr '24

'Highly capable hackers are rooting multiple corporate networks by exploiting a maximum-severity zero-day vulnerability in a firewall product from Palo Alto Networks, researchers said Friday. The vulnerability, which has been under active exploitation for at least two weeks now, allows the hackers with no authentication to execute malicious code with root privileges, the highest possible level of system access, researchers said. The extent of the compromise, along with the ease of exploitation, has earned the CVE-2024-3400 vulnerability the maximum severity rating of 10.0. The ongoing attacks are the latest in a rash of attacks aimed at firewalls, VPNs, and file-transfer appliances, which are popular targets because of their wealth of vulnerabilities and direct pipeline into the most sensitive parts of a network.' -- source: https://arstechnica.com/security/2024/04/highly-capable-hackers-root-corpor… Cheers, Peter

New Spectre V2 Attack Impacts Linux Systems On Intel CPUs
by Peter Reutemann 14 Apr '24

14 Apr '24

'BleepingComputer reports: 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."

In a First, AlmaLinux Patches a Security Hole That Remains Unpatched in Upstream RHEL
by Peter Reutemann 10 Apr '24

10 Apr '24

'AlmaLinux, a three year old Linux distribution that started life as a clone of Red Hat Enterprise Linux, on Tuesday announced that it had created a patch to fix CVE-2024-1086, a security vulnerability that Red Hat evidently doesn’t think is important enough to patch in RHEL right away. “Though this was flagged as something to be fixed in Red Hat Enterprise Linux, Red Hat has only rated this as a moderate impact,” benny Vasquez, chairperson at the AlmaLinux Foundation explained in an article on the distro’s website on Tuesday. “Our users have asked us to patch this more quickly, and as such, we have opted to include patches ourselves. We released this kernel patch to the testing repo last weekend and plan to push it to production on Wednesday, April 3rd.” Since Vasquez’s post a production ready version of the fix was made available through the distro’s repositories, and Red Hat has re-evaluated the threat from its end and raised the severity level from “moderate” to “important.” There is still no sign of a patch from Red Hat, however, although the company has posted several methods for mitigating the threat. “This flaw is trivially exploitable on most RHEL-equivalent systems,” Vasquez said. “There are many proof-of-concept posts available now, including one from our Infrastructure team lead, Jonathan Wright (Dealing with CVE-2024-1086). In multi-user scenarios, this flaw is especially problematic.”' -- source: https://fossforce.com/2024/04/in-a-first-almalinux-patches-a-security-hole-… Cheers, Peter

EndeavourOS Bids Farewell to ARM Branch
by Peter Reutemann 10 Apr '24

10 Apr '24

'In a heartfelt announcement today, Bryan Poerwo, founder and project leader of EndeavourOS, marked the end of its ARM product branch. This project has been part of the EndeavourOS journey since its inception from the remnants of Antergos in 2019. The initiative, which began with the help of a passionate community member known as Pudge, later a leading figure of the EndeavourOS ARM team, aimed to extend the reach of EndeavourOS to ARM devices such as the ODROID N2, ODROID XU4, and Raspberry Pi 4. Over nearly five years, EndeavourOS ARM flourished, witnessing additions like support for the PineBook Pro and Raspberry Pi 5 and implementing a Calamares install option alongside the original scripts. However, the journey was challenging. The rapid advancement of Linux and desktop environments on x86_64 devices contrasted sharply with the slower pace of development in the ARM landscape, presenting a series of obstacles that tested the resolve of the project’s pioneers. The widening gap between ARM and x86_64 architectures, reduced external support, and personal transitions in hardware preferences led to a heartfelt decision to conclude the EndeavourOS ARM project. But not all is lost. As the project ends, the community remains hopeful, inviting anyone willing to carry the torch forward. The project’s GitHub repository continues to be available, serving as a foundation for future endeavors in the ARM Linux space.' -- source: https://linuxiac.com/endeavouros-bids-farewell-to-arm-branch/ Cheers, Peter

TrueNAS Moving From FreeBSD To Debian
by Lawrence D'Oliveiro 09 Apr '24

09 Apr '24

TrueNAS, makers of a turnkey system installation designed for NAS servers, announced close to a month ago that they were changing the emphasis in their product development from “TrueNAS CORE” (which is FreeBSD-based) to “TrueNAS SCALE” (which is Linux-based, specifically Debian-based) <https://www.theregister.com/2024/03/18/truenas_abandons_freebsd/>. This article <https://blocksandfiles.com/2024/04/08/ixsystems-no-one-is-getting-marooned/> gives some more background on the move: Kris Moore, SVP for engineering, told us: “Upstream has shifted. So first of all, ZFS, that’s kind of the heart and soul of TrueNAS and was for FreeNAS as well. Most of that [development] work takes place on Linux these days; features testing, all that happens on Linux. FreeBSD is the thing you port to and you’re done. So that momentum has moved.” ... “We had a huge chunk of our engineering staff spending time improving FreeBSD as opposed to working on features and functionalities. What’s happened now with the transition to having a Debian basis, the people I used to have 90 percent of their time working on FreeBSD, they’re working on ZFS features now … That’s what I want to see; value add for everybody versus sitting around, implementing something Linux had a years ago.” The irony in that is, ZFS was deliberately released by Sun (now Oracle) under a licence that is designed to be incompatible with the GPL that covers the Linux kernel. If you want to argue otherwise, consider that Oracle still refuses to include ZFS with its own Linux distro, preferring to offer you btrfs instead. Of course, you could also view that as a sign of a lack of confidence in its own home-grown filesystem ...

Tip For Repairing Ancient Linux Installations
by Lawrence D'Oliveiro 02 Apr '24

02 Apr '24

Here’s the scenario: there is a malfunctioning server running a really ancient Linux installation (e.g. 2.6.x-series kernel). You boot up with a reasonably recent copy of SystemRescue, mount the machine’s filesystem, try to chroot into it and run a shell ... and it segfaults. Seems there has been a subtle incompatible change in Linux kernel behaviour since those times, to do with the disabling of something called the “vsyscall” mechanism (which is specific to 64-bit x86-based machines, I understand). This was supposed to be a way to speed up certain commonly-executed system calls (I think getting the system time was one of them) by allowing direct transfers to certain entry points with fixed memory addresses for invoking them. It was later decided this was a bad idea (I think for security reasons). The mechanism has not been completely removed (yet), but nowadays it is disabled by default. To get around this, you need to boot SystemRescue with a change to the kernel command-line parameters, adding this item vsyscall=emulate After you get to a shell, you can confirm that this setting is in effect by checking the /proc/self/maps file (the memory mappings for your own process). At the bottom, there should be an entry with “[vdso]” in it, and below that another line with “[vsyscall]”. The presence of the latter line indicates that vsyscall emulation is in effect. This is not present when I check a process on my own machine, for example. Linus is legendary for being a stickler for never, ever breaking backward compatibility for userland. So the reasons for turning this off must have been pretty compelling, for him to agree to it. But the compromise is, it’s still there to be enabled if you really, really need it. There’s a bit more technical info here <https://0xax.gitbooks.io/linux-insides/content/SysCall/linux-syscall-3.html>, if you are interested. By the way, the above page is part of a book beginning here <https://0xax.gitbooks.io/linux-insides/content/>, about the insides of the Linux kernel. The whole book seems to be accessible from that link, but if you step up a level, the site doesn’t seem to have any idea about the existence of that book.

We all know SQL injection attacks are an ongoing problem <https://www.theregister.com/2024/03/26/fbi_cisa_sql_injection/>. What interested me about this article is this part: Software vendors have been advised to use parameterized queries with prepared statements to mitigate SQL injection vulnerabilities. According to the authorities, these allow user-input data to be separated from SQL queries and "better embody a secure by design approach" compared to input sanitization techniques. These are deployed by some vendors, but were branded "brittle" by CISA and the FBI. They said they're also difficult to deploy on a large scale and are more easily bypassed. Funny, that. Every time I post examples of how I dynamically construct SQL query strings with proper quoting of user input, I get yelled at and told to use “parameterized queries” and “prepared statements”, or even an ORM. Yet here we have the security experts saying that that is not a good solution, just like I thought all along.

Mozilla’s privacy service drops a provider with ties to people-search sites
by Peter Reutemann 26 Mar '24

26 Mar '24

'Mozilla's Monitor Plus, a service launched by the privacy-minded tech firm in February, notes on its pitch page that there is "a $240 billion industry of data brokers selling your private information for profit" and that its offering can "take back your privacy." Mozilla's most recent move to protect privacy has been to cut out one of the key providers of Monitor Plus' people-search protections, Onerep. That comes after reporting from security reporter Brian Krebs, who uncovered Onerep CEO and founder Dimitri Shelest as the founder of "dozens of people-search services since 2010," including one, Nuwber, that still sells the very kind of "background reports" that Monitor Plus seeks to curb. Shelest told Krebs in a statement (PDF) that he did have an ownership stake in Nuwber, but that Nuwber has "zero cross-over or information-sharing with Onerep" and that he no longer operates any other people-search sites. Shelest admitted the bad look but said that his experience with people search gave Onerep "the best tech and team in the space." Brandon Borrman, vice president of communications at Mozilla, said in a statement that while "customer data was never at risk, the outside financial interests and activities of Onerep’s CEO do not align with our values." Mozilla is "working now to solidify a transition plan," Borrman said. A Mozilla spokesperson confirmed to Ars today that Mozilla is continuing to offer Monitor Plus, suggesting no pause in subscriptions, at least for the moment.' -- source: https://arstechnica.com/gadgets/2024/03/mozillas-privacy-service-drops-a-pr… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

decrypting PDFs
by Peter Reutemann 22 Mar '24

22 Mar '24

Hi everyone I've long had a problem with being unable to open some PDFs that could be either viewed on Windows or on Google Drive. For some reason, some PDFs appear to be encrypted (but not requiring a password??). Today, I found an approach that allows me to access these files also on my Linux machine using pdftk. pdftk allows you to decrypt PDFs by supplying a password (https://www.ubuntumint.com/remove-password-from-pdf-on-linux/) pdftk <protected>.pdf input_pw <password> output <new>.pdf However, the following seemed to work on these weird PDF files, without having to supply a password: pdftk <protected>.pdf output <new>.pdf And now my PDF viewers (okular, xreader, etc) no longer complain that they can't open the file. :-) Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Formula 1 Chief Appalled to Find Team Using Excel to Manage 20,000 Car Parts
by Lawrence D'Oliveiro 21 Mar '24

21 Mar '24

<https://arstechnica.com/cars/2024/03/formula-1-chief-appalled-to-find-team-…>: The Williams car build workbook, with roughly 20,000 individual parts, was "a joke," Vowles recently told The Race. "Impossible to navigate and impossible to update." This colossal Excel file lacked information on how much each of those parts cost and the time it took to produce them, along with whether the parts were already on order. ... Banks cited Tim Worstall's 2013 contention that Excel could be "the most dangerous software on the planet." Back then, international investment bankers were found manually copying and pasting Excel between Excel sheets to do their work, and it raised alarm.

Database-Based Operating System 'DBOS' Does Things Linux Can't
by Peter Reutemann 19 Mar '24

19 Mar '24

'Databricks CTO Matei Zaharia "said that Databricks had to keep track of scheduling a million things," remembers adjunct MIT professor Michael Stonebraker. " He said that this can't be done with traditional operating system scheduling, and so this was done out of a Postgres database. And then he started to whine that Postgres was too slow, and I told him we can do better than that...." This resulted in DBOS — short for "database operating system" — which they teamed up to build with teams Stanford and MIT, according to The Next Platform: They founded a company to commercialize the idea in April 2023 and secured $8.5 million initial seed funding to start building the real DBOS. Engine Ventures and Construct Capital led the funding, along with Sinewave and GutBrain Ventures... "The state that the operating system has to keep track of — memory, files, messages, and so on — is approximately linear to the resources you have got," says Stonebraker. "So without me saying another word, keeping track of operating system state is a database problem not addressed by current operating system schedulers. Moreover, OLTP [Online Transaction Processing] database performance has gone up dramatically, and that is why we thought instead of running the database system in user space on top of the operating system, why don't we invert our thinking 180 degrees and run the operating system on top of the database, with all of the operating services are coded in SQL...?" For now, DBOS can give the same kind of performance as that full blown Linux operating system, and thanks to the distributed database underpinnings of its kernel, it can do things that a Linux kernel just cannot do... One is provide reliable execution, which means that if a program running atop DBOS is ever interrupted, it starts where it left off and does not have to redo its work from some arbitrary earlier point and does not crash and have to start from the beginning. And because every little bit of the state of the operating system — and therefore the applications that run atop it — is preserved, you can go backwards in time in the system and restart the operating system if it experiences some sort of anomaly, such as a bad piece of application software running or a hack attack. You can use this "time travel" feature, as Stonebraker calls it, to reproduce what are called heisenbugs — ones that are very hard to reproduce precisely because there is no shared state in the distributed Linux and Kubernetes environment and that are increasingly prevalent in a world of microservices. The other benefit of the DBOS is that it presents a smaller attack surface for hackers, which boosts security, and that you analyze the metrics of the operating system in place since they are already in a NoSQL database that can be queried rather than aggregating a bunch of log files from up and down the software stack to try to figure out what is going on... There is also a custom tier for DBOS, which we presume costs money, that can use other databases and datastores for user application data, stores more than three days of log data, can have multiple users per account, that adds email and Slack support with DBOS techies, and that is available on other clouds as well as AWS. The operating system kernel/scheduler "is itself largely a database," with services written in TypeScript, according to the article. The first iteration used the FoundationDB distributed key-value store for its scheduling core (open sourced by Apple in 2018), according to the article — "a blazingly fast NoSQL database... Stonebraker says there is no reason to believe that DBOS can't scale across 1 million cores or more and support Java, Python, and other application languages as they are needed by customers..." And the article speculates they could take things even further. "There is no reason why DBOS cannot complete the circle and not only have a database as an operating system kernel, but also have a relational database as the file system for applications."' -- source: https://developers.slashdot.org/story/24/03/18/0038232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Ends its Privacy-Friendly GPS-Style Location Service
by Peter Reutemann 18 Mar '24

18 Mar '24

'Mozilla Location Service offered "a free, open way to offer GPS-style location detection features" for developers on devices without GPS hardware, remembers the Linux blog OMG Ubuntu. It used signals like Wi-Fi access points and Bluetooth beacons "without any of the privacy implications most competing geolocation services have." But Friday they reported that Mozilla "has announced it is ending access to Mozilla Location Service (MLS), which provides accurate, privacy-respecting, and crowdsourced geolocation data." Developers and 3rd-party projects that use MLS to detect a users' location, such as the freedesktop.org location framework GeoClue, which is used by apps like GNOME Maps and Weather, have only a few months left to continue using the service... In late March, POST data submissions will return 403 responses. Finally, on June 12, all 3rd-party API keys will be removed and MLS data only accessible by Mozilla... MLS' accuracy has declined in recent years. Patent infringement claims in 2019 saw Mozilla reach a settlement to avoid litigation. As part of that settlement it was forced to make changes to MLS that impacted its ability to invest in (commercially exploit?) and improve the service. The article notes that GeoClue "already supports multiple location detection methods, including IP-based ones," so it should continue operating. "But the sad reality is that there just aren't a lot of free, open, privacy-friendly, accurate, and (rather importantly for a framework built in to Linux desktops) reliable alternatives to Mozilla Location Services, which has built up a colossal 'signal map' from which to pinpoint locations." "We are grateful for the contributions of the community to MLS to both the code and the dataset," a Mozilla senior engineering manager said in a statement.' -- source: https://tech.slashdot.org/story/24/03/17/2150221/mozilla-ends-its-privacy-f… I wasn't even aware that Mozilla was offering such a service...

1986 Presentation On Setting A Computer’s Clock Correctly
by Lawrence D'Oliveiro 18 Mar '24

18 Mar '24

One of the recent additions to the Bitsavers vintage computing collection is this presentation from 1986 <http://bitsavers.trailing-edge.com/pdf/ibm/share/SHARE67_Presentation_on_Se…> at a session of SHARE (one of the IBM user groups), on how to ensure your computer’s time is set correctly. Remember, this was before NTP. But there was already a worldwide network of atomic clocks, keeping synchronization with each other, and there were shortwave stations, like WWV in Boulder, Colorado, that would broadcast pips once per second, synchronized to the atomic clock network. And there were even consumer-level gadgets, like the one mentioned in the article from Heath, that would automatically decode those broadcasts and output a time code a computer could read. The article has some nice background info. Like did you know there can be up to a 1-second discrepancy between GMT and UTC? (Actually I think from other sources the limit might be more like 0.9 seconds.) IBM’s mainframe OS developers were perceptive enough to realize that it can be useful to have the computer keep time in GMT, and maintain an offset for calculating local time. Particular site admins could of course have the choice of using local time for the system time, and setting the offset to zero. Changing the offset for daylight saving could be a fraught procedure, though. The level of confusion it could cause for running applications was such that it was safer to do a reboot. One little item I don’t recall coming across before, another of those NASA programming screwups: One of the famous programming mistakes of all time was by the programmer who thought the earth revolved on its axis once every 24 hours and used that fact to calculate landing sites for the Mercury space flights. Our first astronauts spent a lot more time in the water than they should have because of that.

Free/Libre 'GnuCOBOL' Compiler Reaches Maturity, Can Compete with Proprietary Offerings
by Peter Reutemann 18 Mar '24

18 Mar '24

'After 20 years of development, the open source GnuCOBOL "has reached an industrial maturity and can compete with proprietary offers in all environments," said OCamlPro founder and GnuCOBOL contributor Fabrice Le Fessant, in a FOSDEM talk about the technology. GnuCOBOL turns COBOL source code into executable applications. It is very cross-platform, running Linux, BSD, many proprietary Unixes, macOS, and Windows, even Android. And the latest version, v.32, is being used in many commercial settings... Sobisch noted that the GnuCOBOL is seeing a lot of commercial deployments, such as for banking back-end apps, many of which are being migrated from Micro Focus, with users reporting performance improvements as a result. The French DGFIP federal agency moved from a GCOS mainframe to GnuCOBOL, with the help of Le Fessant's firm. Originally called OpenCOBOL, the project was started in 2002 and renamed GnuCOBOL in 2013. In the past three years, it has received attention from 13 contributors with 460 commits. Most Linux package managers have a copy of GnuCOBOL for the program for downloading... It can compile to C code (C89+), making it extremely portable, from mainframes to Raspberry Pi's, Sobisch said... Also new is SuperBOL, a development studio for GnuCOBOL developed by Le Fessant's OCamlPro. It runs as a VSCode Extension and features a full COBOL processor (written in OCaml).

Never-before-seen Linux malware gets installed using 1-day exploits
by Peter Reutemann 12 Mar '24

12 Mar '24

'Researchers have unearthed Linux malware that circulated in the wild for at least two years before being identified as a credential stealer that’s installed by the exploitation of recently patched vulnerabilities. The newly identified malware is a Linux variant of NerbianRAT, a remote access Trojan first described in 2022 by researchers at security firm Proofpoint. Last Friday, Checkpoint Research revealed that the Linux version has existed since at least the same year, when it was uploaded to the VirusTotal malware identification site. Checkpoint went on to conclude that Magnet Goblin—the name the security firm uses to track the financially motivated threat actor using the malware—has installed it by exploiting “1-days,” which are recently patched vulnerabilities. Attackers in this scenario reverse engineer security updates, or copy associated proof-of-concept exploits, for use against devices that have yet to install the patches. Checkpoint also identified MiniNerbian, a smaller version of NerbianRAT for Linux that’s used to backdoor servers running the Magento ecommerce server, primarily for use as command and control servers that devices infected by NerbianRAT connect to. Researchers elsewhere have reported encountering servers that appear to have been compromised with MiniNerbian, but Checkpoint Research appears to have been the first to identify the underlying binary.' -- source: https://arstechnica.com/security/2024/03/never-before-seen-linux-malware-ge… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux 6.9 Will Be the First To Top 10 Million Git Objects
by Peter Reutemann 12 Mar '24

12 Mar '24

'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.' -- source: https://linux.slashdot.org/story/24/03/11/1620223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

“We Had To Educate Oracle About Our Contract”
by Lawrence D'Oliveiro 08 Mar '24

08 Mar '24

Slightly chilling words to hear, don’t you think? Corporations that do volume deals with proprietary suppliers like Oracle and SAP have to agree to allow periodic audits by the vendor to ensure they are complying with the licence terms. Vendors have been known to try to pull a fast one during these audits. This customer <https://www.theregister.com/2024/03/06/oracle_audits/> mentions that Oracle, in particular, had a tendency to assume the software was licensed under their current terms, when in fact the contract was agreed under quite different, older terms. Hence the need to keep “educating” (i.e. reminding) the vendor about what the correct criteria were.

Fedora Workstation 41 To No Longer Install GNOME X.Org Session By Default
by Peter Reutemann 08 Mar '24

08 Mar '24

'Michael Larabel writes via Phoronix: Fedora Workstation has long defaulted to using GNOME's Wayland session by default, but it has continued to install the GNOME X.Org session for fallback purposes or those opting to use it instead. But for the Fedora Workstation 41 release later in the year, there is a newly-approved plan to no longer have that GNOME X.Org session installed by default. Recently there was a Fedora Workstation ticket opened to no longer install the GNOME X.Org session by default. This is just about whether the X.Org session is pre-installed but would continue to live in the repository for those wanting to explicitly install it. The Fedora Workstation working group decided to go ahead with this change for the Fedora 41 cycle, not the upcoming Fedora 40 release. So pending any obstacles by FESCo, which is unlikely. Fedora Workstation 41 will not be installing the GNOME X.Org session by default.

French Court Issues Damages Award For Violation of GPL
by Peter Reutemann 04 Mar '24

04 Mar '24

'Some news from "Copyleft Currents", the blog of open-source/IP lawyer Heather Meeker: On February 14, 2024, the Court of Appeal of Paris issued an order stating that Orange, a major French telecom provider, had infringed the copyight of Entr'Ouvert's Lasso software and violated the GPL. They ordered Orange to pay €500,000 in compensatory damages and €150,000 for moral damages. This case has been ongoing for many years. Entr'ouvert is the publisher of Lasso, a reference library for the Security Assertion Markup Language (SAML) protocol, an open standard for identity providers to authenticate users and pass authentication tokens to online services. This is the open protocol that enables single sign-on (SSO). The Lasso product is dual licensed by Entr'Ouvert under GPL or commercial licenses. In 2005, Orange won a contract with the French Agency for the Development of Electronic Administration to develop parts of the service-public.fr portal, which allows users to interact online with the government for administrative procedures. Orange used the Lasso software in the solution, but did not pass on the rights to its modifications free of charge under GPL, or make the source code to its modifications available. Entr'Ouvert sued Orange in 2010, and the case wended its way through the courts, turning on, among other things, issues of proof of Entr'Ouvert 's copyright interest in the software, and whether the case properly sounded in breach of contract or copyright infringement... The compensatory damages were based on both lost profits of the plaintiff and disgorgement of profits of Orange. Moral damages compensate the plaintiff for harm to reputation or other non-monetary injury.' -- source: https://news.slashdot.org/story/24/03/03/030200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Paying People To Work on Open Source is Good Actually'
by Peter Reutemann 01 Mar '24

01 Mar '24

'Jacob Kaplan-Moss, one of the lead developers of Django, writes in a long post that he says has come from a place of frustration: [...] Instead, every time a maintainer finds a way to get paid, people show up to criticize and complain. Non-OSI licenses "don"t count" as open source. Someone employed by Microsoft is "beholden to corporate interests" and not to be trusted. Patreon is "asking for handouts." Raising money through GitHub sponsors is "supporting Microsoft's rent-seeking." VC funding means we're being set up for a "rug pull" or "enshitification." Open Core is "bait and switch." None of this is hypothetical; each of these examples are actual things I've seen said about maintainers who take money for their work. One maintainer even told me he got criticized for selling t-shirts! Look. There are absolutely problems with every tactic we have to support maintainers. It's true that VC investment comes with strings attached that often lead to problems down the line. It sucks that Patreon or GitHub (and Stripe) take a cut of sponsor money. The additional restrictions imposed by PolyForm or the BSL really do go against the Freedom 0 ideal. I myself am often frustrated by discovering that some key feature I want out of an open core tool is only available to paid licensees. But you can criticize these systems while still supporting and celebrating the maintainers! Yell at A16Z all you like, I don't care. (Neither do they.) But yelling at a maintainer because they took money from a VC is directing that anger in the wrong direction. The structural and societal problems that make all these different funding models problematic aren't the fault of the people trying to make a living doing open source. It's like yelling at someone for shopping at Dollar General when it's the only store they have access to. Dollar General's predatory business model absolutely sucks, as do the governmental policies that lead to food deserts, but none of that is on the shoulders of the person who needs milk and doesn't have alternatives.' -- source: https://news.slashdot.org/story/24/02/29/0746221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

HDMI Forum Rejects Open-Source HDMI 2.1 Driver Support Sought By AMD
by Peter Reutemann 01 Mar '24

01 Mar '24

'Michael Larabel, reporting at Phoronix: One of the limitations of AMD's open-source Linux graphics driver has been the inability to implement HDMI 2.1+ functionality on the basis of legal requirements by the HDMI Forum. AMD engineers had been working to come up with a solution in conjunction with the HDMI Forum for being able to provide HDMI 2.1+ capabilities with their open-source Linux kernel driver, but it looks like those efforts for now have concluded and failed. For three years there has been a bug report around 4K(a)120Hz being unavailable via HDMI 2.1 on the AMD Linux driver. Similarly, there have been bug reports like 5K @ 240Hz not possible either with the AMD graphics driver on Linux. As covered back in 2021, the HDMI Forum closing public specification access is hurting open-source support. AMD as well as the X.Org Foundation have been engaged with the HDMI Forum to try to come up with a solution to be able to provide open-source implementations of the now-private HDMI specs. AMD Linux engineers have spent months working with their legal team and evaluating all HDMI features to determine if/how they can be exposed in their open-source driver. AMD had code working internally and then the past few months were waiting on approval from the HDMI Forum. Sadly, the HDMI Forum has turned down AMD's request for open-source driver support.' -- source: https://it.slashdot.org/story/24/02/29/076217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

by Peter Reutemann 29 Feb '24

29 Feb '24

'Michael Larabel reports via Phoronix: Back in 2022 Cloudflare announced they were ditching Nginx for an in-house, Rust-written software called Pingora. Today Cloudflare is open-sourcing the Pingora framework. Cloudflare announced today that they have open-sourced Pingora under an Apache 2.0 license. Pingora is a Rust async multi-threaded framework for building programmable network services. Pingora has long been used internally within Cloudflare and is capable of sustaining a lot of traffic while now Pingora is being open-sourced for helping to build infrastructure outside of Cloudflare.' -- source: https://news.slashdot.org/story/24/02/28/2352248 -- github: https://github.com/cloudflare/pingora Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

KDE Plasma 6 Released
by Peter Reutemann 29 Feb '24

29 Feb '24

'"Today, the KDE Community is announcing a new major release of Plasma 6.0 and Gear 24.02," writes longtime Slashdot reader jrepin. "The new version brings new windows and desktop overview effects, improved color management, a cleaner theme, better overall performance, and much more." From the announcement: KDE Plasma is a modern, feature-rich desktop environment for Linux-based operating systems. Known for its sleek design, customizable interface, and extensive set of applications, it is also open source, devoid of ads, and makes protecting your privacy and personal data a priority. With Plasma 6, the technology stack has undergone two major upgrades: a transition to the latest version of the application framework, Qt 6, and a migration to the modern Linux graphics platform, Wayland. We will continue providing support for the legacy X11 session for users who prefer to stick with it for now. [...] KDE Gear 24.02 brings many applications to Qt 6. In addition to the changes in Breeze, many applications adopted a more frameless look for their interface.' -- source: https://tech.slashdot.org/story/24/02/28/2137237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GitHub besieged by millions of malicious repositories in ongoing attack
by Peter Reutemann 29 Feb '24

29 Feb '24

'GitHub is struggling to contain an ongoing attack that’s flooding the site with millions of code repositories. These repositories contain obfuscated malware that steals passwords and cryptocurrency from developer devices, researchers said. The malicious repositories are clones of legitimate ones, making them hard to distinguish to the casual eye. An unknown party has automated a process that forks legitimate repositories, meaning the source code is copied so developers can use it in an independent project that builds on the original one. The result is millions of forks with names identical to the original one that add a payload that’s wrapped under seven layers of obfuscation. To make matters worse, some people, unaware of the malice of these imitators, are forking the forks, which adds to the flood.' -- source: https://arstechnica.com/security/2024/02/github-besieged-by-millions-of-mal… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Open Documentation Academy' Offers On-Ramp To OSS
by Peter Reutemann 28 Feb '24

28 Feb '24

'"Documentation authors at Canonical have launched the Open Documentation Academy to offer an easy way to get started contributing to open-source projects," writes longtime Slashdot reader tykev. From the blog post: Open and inclusive collaboration, and the sharing of ideas, remains the best way to develop software (and to do many other things!), but we also recognise that this "getting involved" step can be difficult. Where do you start? Who do you ask? What needs to be done? We all very much want to help people become open source contributors by building an on-ramp process. It may take some time, and we will need to adapt, but this is exactly why we've started our Open Documentation Academy. To help you get involved, the Open Documentation Academy provides a curated list of documentation tasks. Choose one, let us know, and get started. Tasks include testing and fixing tutorials, updating the outdated, restructuring large documents, and anything else you may want to suggest. Our list is growing, and a big part of the Documentation Academy will be ensuring there's always a wide range of tasks available, across as many projects and technologies as possible. And of course, we're here to help. We'll guide you through your first contributions, provide advice on approaches, and help you build your confidence.

Tumblr and Wordpress Are Preparing To Sell User Data To OpenAI and Midjourney, Report Says
by Peter Reutemann 28 Feb '24

28 Feb '24

'Tumblr and Wordpress are preparing to sell user data to Midjourney and OpenAI, 404Media reported Tuesday, citing a source with internal knowledge about the deals and internal documents. From the report: The exact types of data from each platform going to each company are not spelled out in documentation we've reviewed, but internal communications reviewed by 404 Media make clear that deals between Automattic, the platforms' parent company, and OpenAI and Midjourney are imminent. The internal documentation details a messy and controversial process within Tumblr itself. One internal post made by Cyle Gage, a product manager at Tumblr, states that a query made to prepare data for OpenAI and Midjourney compiled a huge number of user posts that it wasn't supposed to. It is not clear from Gage's post whether this data has already been sent to OpenAI and Midjourney, or whether Gage was detailing a process for scrubbing the data before it was to be sent.

US Government Demands Memory-Safe Programming Languages
by Lawrence D'Oliveiro 28 Feb '24

28 Feb '24

The US Office of the National Cyber Director has put out a report on “a path towards secure and measurable software” <https://devclass.com/2024/02/27/white-house-demands-memory-safe-programming…>. It talks a lot about memory safety, including hardware techniques such as the old “capabilities” idea being resurrected in the CHERI project. And the Rust Foundation has chimed in with some comments about use of their language which is specifically designed to enforce memory safety. But a group of C++ fans has counterclaimed that memory safety is only “a very small part of security”, and that “C++ benefits from having a formal specification, a fully-specified memory model, and an active community of users and implementers”, and that education can improve the quality of code written in C and C++. It also tries to imply that Rust is somehow less desirable because it lacks a formal specification.

Is Windows 64-Bit Yet?
by Lawrence D'Oliveiro 27 Feb '24

27 Feb '24

Given that 64-bit Windows has been shipping for so long, you would think most Windows software, particularly Microsoft’s own software, would have made the transition from 32-bit long ago. After all, on a typical 64-bit Linux system, everything is 64-bit, and has been that way since the early days. So I was mildly surprised to discover that Visual Studio only became 64-bit in November 2021. And today I am even more surprised to discover that the change broke its own Windows Forms framework, and a fix is still not available to this day <https://devclass.com/2024/02/26/microsoft-struggles-to-address-fallout-from…>.

The State Of IoT
by Lawrence D'Oliveiro 23 Feb '24

23 Feb '24

This backflip from Microsoft <https://www.theregister.com/2024/02/21/microsoft_azure_iot_central/> retracting an earlier announcement that seemingly undermined a major part of its “Internet-of-Things” efforts seems to do little to clear the confusion. I found this part of the report quite revealing: The insider also pointed out that vendors struggle to produce value for organizations developing and deploying IoT applications. While the industry underestimated the scale of the challenge in connecting thousands of sensors, each of which could generate 86,400 values per day, it also failed to form a commercial model that worked for everyone. Vendors were focused only on owning the platform and were reluctant to build applications on anyone else's, creating a stalemate, the insider said. Meanwhile, the “maker” movement continues on its merry way, building its applications and toolkits on (and for) open-source platforms like the Raspberry Pi and Arduino, while completely failing to spend billions of dollars on proprietary products. And the proprietary companies can do nothing but search desperately for some lever that will give them that valuable vendor lock-in, but all they can achieve is wrestle each other to a stalemate. Me, I consider that a win-win situation. ;)

Linux Becomes a CVE Numbering Authority (Like Curl and Python). Is This a Turning Point?
by Peter Reutemann 19 Feb '24

19 Feb '24

'From a blog post by Greg Kroah-Hartman: As was recently announced, the Linux kernel project has been accepted as a CVE Numbering Authority (CNA) for vulnerabilities found in Linux. This is a trend, of more open source projects taking over the haphazard assignments of CVEs against their project by becoming a CNA so that no other group can assign CVEs without their involvment. Here's the curl project doing much the same thing for the same reasons. I'd like to point out the great work that the Python project has done in supporting this effort, and the OpenSSF project also encouraging it and providing documentation and help for open source projects to accomplish this. I'd also like to thank the cve.org group and board as they all made the application process very smooth for us and provided loads of help in making this all possible. As many of you all know, I have talked a lot about CVEs in the past, and yes, I think the system overall is broken in many ways, but this change is a way for us to take more responsibility for this, and hopefully make the process better over time. It's also work that it looks like all open source projects might be mandated to do with the recent rules and laws being enacted in different parts of the world, so having this in place with the kernel will allow us to notify all sorts of different CNA-like organizations if needed in the future. Kroah-Hartman links to his post on the kernel mailing list for "more details about how this is all going to work for the kernel." [D]ue to the layer at which the Linux kernel is in a system, almost any bug might be exploitable to compromise the security of the kernel, but the possibility of exploitation is often not evident when the bug is fixed. Because of this, the CVE assignment team are overly cautious and assign CVE numbers to any bugfix that they identify. This explains the seemingly large number of CVEs that are issued by the Linux kernel team... No CVEs will be assigned for unfixed security issues in the Linux kernel, assignment will only happen after a fix is available as it can be properly tracked that way by the git commit id of the original fix. No CVEs will be assigned for any issue found in a version of the kernel that is not currently being actively supported by the Stable/LTS kernel team. alanw (Slashdot reader #1,822) worries this could overwhelm the CVE infrastructure, pointing to an ongoing discussion at LWN.net. But reached for a comment, Greg Kroah-Hartman thinks there's been a misunderstanding. He told Slashdot that the CVE group "explicitly asked for this as part of our application... so if they are comfortable with it, why is no one else?"' -- source: https://linux.slashdot.org/story/24/02/17/1811258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Nginx core developer quits project in security dispute, starts “freenginx” fork
by Peter Reutemann 16 Feb '24

16 Feb '24

'A core developer of Nginx, currently the world's most popular web server, has quit the project, stating that he no longer sees it as "a free and open source project… for the public good." His fork, freenginx, is "going to be run by developers, and not corporate entities," writes Maxim Dounin, and will be "free from arbitrary corporate actions." Dounin is one of the earliest and still most active coders on the open source Nginx project and one of the first employees of Nginx, Inc., a company created in 2011 to commercially support the steadily growing web server. Nginx is now used on roughly one-third of the world's web servers, ahead of Apache. Nginx Inc. was acquired by Seattle-based networking firm F5 in 2019. Later that year, two of Nginx's leaders, Maxim Konovalov and Igor Sysoev, were detained and interrogated in their homes by armed Russian state agents. Sysoev's former employer, Internet firm Rambler, claimed that it owned the rights to Nginx's source code, as it was developed during Sysoev's tenure at Rambler (where Dounin also worked). While the criminal charges and rights do not appear to have materialized, the implications of a Russian company's intrusion into a popular open source piece of the web's infrastructure caused some alarm. Sysoev left F5 and the Nginx project in early 2022. Later that year, due to the Russian invasion of Ukraine, F5 discontinued all operations in Russia. Some Nginx developers still in Russia formed Angie, developed in large part to support Nginx users in Russia. Dounin technically stopped working for F5 at that point, too, but maintained his role in Nginx "as a volunteer," according to Dounin's mailing list post. Dounin writes in his announcement that "new non-technical management" at F5 "recently decided that they know better how to run open source projects. In particular, they decided to interfere with security policy nginx uses for years, ignoring both the policy and developers' position." While it was "quite understandable," given their ownership, Dounin wrote that it means he was "no longer able to control which changes are made in nginx," hence his departure and fork.' -- source: https://arstechnica.com/information-technology/2024/02/nginx-key-developer-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Asahi Linux Project's OpenGL Support On Apple Silicon Officially Surpasses Apple's
by Peter Reutemann 16 Feb '24

16 Feb '24

'Andrew Cunningham reports via Ars Technica: For around three years now, the team of independent developers behind the Asahi Linux project has worked to support Linux on Apple Silicon Macs, despite Apple's total lack of involvement. Over the years, the project has gone from a "highly unstable experiment" to a "surprisingly functional and usable desktop operating system." Even Linus Torvalds has used it to run Linux on Apple's hardware. The team has been steadily improving its open source, standards-conformant GPU driver for the M1 and M2 since releasing them in December 2022, and today, the team crossed an important symbolic milestone: The Asahi driver's support for the OpenGL and OpenGL ES graphics have officially passed what Apple offers in macOS. The team's latest graphics driver fully conforms with OpenGL version 4.6 and OpenGL ES version 3.2, the most recent version of either API. Apple's support in macOS tops out at OpenGL 4.1, announced in July 2010. Developer Alyssa Rosenzweig wrote a detailed blog post that announced the new driver, which had to pass "over 100,000 tests" to be deemed officially conformant. The team achieved this milestone despite the fact that Apple's GPUs don't support some features that would have made implementing these APIs more straightforward. "Regrettably, the M1 doesn't map well to any graphics standard newer than OpenGL ES 3.1," writes Rosenzweig. "While Vulkan makes some of these features optional, the missing features are required to layer DirectX and OpenGL on top. No existing solution on M1 gets past the OpenGL 4.1 feature set... Without hardware support, new features need new tricks. Geometry shaders, tessellation, and transform feedback become compute shaders. Cull distance becomes a transformed interpolated value. Clip control becomes a vertex shader epilogue. The list goes on." Now that the Asahi GPU driver supports the latest OpenGL and OpenGL ES standards -- released in 2017 and 2015, respectively -- the work turns to supporting the low-overhead Vulkan API on Apple's hardware. Vulkan support in macOS is limited to translation layers like MoltenVK, which translates Vulkan API calls to Metal ones that the hardware and OS can understand. [...] Rosenzweig's blog post didn't give any specific updates on Vulkan except to say that the team was "well on the road" to supporting it. In addition to supporting native Linux apps, supporting more graphics APIs in Asahi will allow the operating system to take better advantage of software like Valve's Proton, which already has a few games written for x86-based Windows PCs running on Arm-based Apple hardware.
