      • Dell XPS 13 Developer Edition review: The perfect machine for normies to try Linux

        Linux, it’s a scary word for some and an unknown realm for others. For many, Linux is a way of life, and they’ve been using it for a very long time. Even if you’ve never heard of Linux and are scared to try it, you probably already use it daily. This review of the Dell XPS 13 Developer Edition isn’t for those who are experienced. This review is for the normies.

        Linux is widely used on server farms all over the world. Your email, your website host, and even your employer likely use Linux in some form. Even your Android device is a flavor of Linux, so you’re probably using it day in and day out. The Dell XPS 13 Developer Edition brings Linux to the average person’s fingertips with no need to go through installing or configuring ahead of time.

        While I have installed and configured many Linux distros on many different laptops over the years, I have to admit having the work done for you is half the battle. I know many Linux lovers will disagree with me, but they’re not thinking with the same head a normal user would. Turn back now Linux purists; this particular Dell XPS 13 Developer Editon review is not for you. If you’re just a normal Windows or Mac user looking for an alternative and wondering what this device is all about, let’s jump into it.

    • Kernel Space

      • Linux Kernel 5.12 Released

        After two months of development, Linus Torvalds has released the latest version of the Linux kernel, saying that “despite the extra week, this was actually a fairly small release overall.”

        According to the KernelNewbies page, this release introduces idmapped mounts, which let you “map the user id of a mount to a different one. This makes it possible to share files more easily between multiple users or multiple machines especially in complex scenarios.”

      • BPF: Application Development and libbpf

        A while back, I posted a blog series on BPF, including some suggestions about setting up a BPF development environment. Much has changed since then in terms of BPF features, so it's worth revisiting how BPF applications are developed now.

        The key change - at least for the BPF projects I work on - is that libbpf has become central to BPF application development. Why?

        The SYS_BPF syscall is the Swiss Army knife of BPF; it allows you to for example inject a BPF program into the kernel and verify it, create associated maps and attach the program to its target. When these basic tasks were all that was needed, they could be carried out using simple wrappers to the SYS_BPF system call.

        However BPF programs do a lot more now and there's a huge amount of interplay between userspace and kernel required to set up a program to run. libbpf solves a bunch of problems for you. I'll try and describe a few of them here.

      • Intel Bus Lock Detection Merged For Linux 5.13 - Phoronix

        Intel's code for Linux kernel bus lock detection that works in conjunction with newer Intel CPUs has landed in the Linux kernel.

        Last year Intel contributed split lock detection for Linux 5.7+ for finding out when an atomic instruction ends up spanning multiple cache lines. Those split locks can incur significant performance penalties and now that kernel code has been extended to cover bus lock detection too with Linux 5.13+ on recent Intel processors.

      • Updated FUTEX2 System Call Patches Posted For Helping Wine/Proton, Other Use-Cases - Phoronix

        It's been several months since the last round of FUTEX2 patches for this system call to address the shortcomings of the current FUTEX system call. FUTEX2, which is designed in part with Wine/Proton in mind for better matching Windows semantics, has now seen a third iteration of the patches.

        FUTEX2 aims to better match the behavior of Windows and can wait on multiple futexes, among other improvements over the original system call. It's important for Wine/Proton and ultimately Steam Play for enjoying Windows games on Linux with optimal performance and reliability.

      • Linux Kernel Runtime Guard 0.9.1 Is Released - LinuxReviews

        The Linux Kernel Runtime Guard (LKRG) is a Linux kernel security module developed by Openwall for security enthusiasts, Internet-facing production servers and hosting providers that provides additional run-time integrity and security checks for the Linux kernel. The latest version adds support for CONFIG_HAVE_STATIC_CALL on Linux 5.10+ and a fix for a false positive bug on machines with SELinux enabled. make install no longer enables it by default. There is, instead, a message explaining how to enable it using the systemd service file it provides.

      • Stupid RCU Tricks: A tour through rcutorture - Paul E. McKenney's Journal — LiveJournal

        Although Linux-kernel RCU gets most of the attention, without rcutorture, RCU would not be what it is today. To see this, note that the old saying “If it ain't tested, it don't work!” is if anything more valid today than it was back then. After all, software has not gotten any simpler, workloads have not become less demanding, and systems have not grown smaller, except in terms of physical size. That said, the decrease in size has been truly impressive. Back when Jack and I invented RCU, the hardware contained in my laptop would have filled no fewer than fifteen standard racks, and that ignores the hardware that simply was not available back then, and also ignores the reliability issues that would have resulted from such an imposing agglomeration of hardware.

      • Linux Software Raid 1 Setup

        RAID 1 is a hard disk configuration where the contents from one hard disk are mirrored onto another. This provides the user with some redundancy in case a disk fails. On your Linux system, the two hard drives are represented as a single file system. But in the background, making changes to your files is actually writing the changes to two disks at the same time. You can also add more than two disks to the configuration, as long as you keep the number even. Otherwise, something like RAID 5 will be more suitable.

        There are many ways to configure a RAID setup. One of the easiest and most accessible ways is through the mdadm software package, which can be installed and used on any major Linux distribution. This is easier than some other RAID setups, since it doesn't require any special hardware (like a RAID controller) and isn't that hard to configure.

        In this guide, we'll go through the step by step instructions to install and setup mdadm on Linux, and create a RAID 1 configuration for two hard disks. Our example scenario will consist of two empty hard disks that are each 10 GB in size. This is in addition to our main hard disk, which is just used for the operating system.

      • Jon Chiappetta: Small Network Speed Testing Web Server

        So I wanted to test the internal LAN speeds of our wireless bridge, switches, and cables in between – from one end of the network to the other. There is an old iMac running on one side of the bridge and I didn’t want the speed test to slow down due to disk I/O reasons. I wrote a small python based web server which pre-initializes a memory buffer with random data and then sends random chunks inside of it throughout the fake “download” process (jumps around from index to index).

      • Linux Gaming vs. Windows Gaming: Everything You Need to Know

        Linux has made significant strides over the last couple of years when it comes to gaming. But has it reached the stage where it can be considered as a viable alternative to Windows? Well, the answer depends on you – what games you play and how you use your OS apart from gaming.

        If you are looking for the OS with the most natively supported games, then Windows takes the cake – no argument!

        However, it’s more than likely you don’t plan on playing “every” PC game out there! Maybe you have a few favorites! And Linux’s gaming catalog covers almost all the popular titles, so you are extremely likely to find your favorite game compatible on Linux. Also, believe it or not, but some games actually perform better on Linux than Windows – provided you are running on the same hardware.

        As such, it’s clearly understandable why the PC gaming community is constantly engaged in a heated debate over Linux vs. Windows gaming – which is better. And so, for this read, we have decided to shed some light on the topic – giving you the pros and cons of both OSes in terms of gaming.

        Now that there's a Linux port available that performs well, this might perhaps entice a few people into Humble Choice to pick up a good deal. Usually it costs $39.99 on Steam without any discounts, so the Humble Choice for May is a good way to get it which usually costs about $19.99 for the whole set. Humble have also announced that for May's Humble Choice there will be Darksiders Genesis, Hellpoint, and 9 more games so it seems like overall it's going to be quite a good one.

        • KaOS 2021.04

          Time goes fast, it is eight years ago this week that KaOS started, so this is kind of an April anniversary release.

          It has also been eight years that the same initramfs creation tool has been used (Mkinitcpio), but with Dracut being the more widely used and constantly maintained, it is time to move to this new tool for KaOS. For almost two years Mkinitcpio did not have a maintainer and upstream had talks about abandoning this tool. This will be a major change and will require lots of work for the ISO creation, but a start has been made, the linux-next kernel already defaults to Dracut for initramfs creation.

        • KaOS Linux Celebrates 8th Anniversary with New ISO Release Featuring KDE Gear 21.04

          KaOS 2021.04 is here as the first ISO snapshot to switch to Dracut as the default tool for creating the Linux boot image (initramfs), replacing Mkinitcpio, which is no longer supported. This is a major change and requires a lot of work to be fully integrates, but, for now, the linux-next kernel defaults to Dracut for initramfs creation.

          Since KaOS focuses on Qt and KDE, the KaOS 2021.04 release ships with the KDE Plasma 5.21.3 desktop environment, which is accompanied by the latest KDE Gear 21.04 and KDE Frameworks 5.81 software suites, all built against the Qt 5.15.2 open-source application framework.

          I must confess, I was guilty of being reactionary when I first read and wrote about a situation between two IBM employees, one of whom is a Linux kernel maintainer. I reacted because open-source is near and dear to my heart, something I've been passionate about since the late nineties. But my initial reaction was based on only one side of the story, the kernel maintainer's. Since then, I've had a chance to speak with IBM, hear their account of what happened and gain a better understanding of how the company works to support the Linux open-source community.

        • Fedora 34 Released With GNOME 40 And Wayland By Default

          Fedora Linux 34 is one of the major releases in Fedora’s history and a bold one. The Fedora Project’s emphasis on delivering the latest open source updates with all levels of users in mind, from beginners to experts.

          Fedora team announced the Fedora 34 release across workstations, spins, and servers. The latest version on this popular Linux distribution comes with Linux Kernel 5.11 which brings support for the latest hardware across processors, graphics cards, ports, and other devices.


          Btrfs has been the default filesystem for Fedora Workstations since Fedora 33, but the Fedora Project team has done one better in Fedora 34. In this release, the zstd compression is made as default when using Btrfs. This compression will be essential for increasing read and write performance of larger files, with the potential to speed up related workflows.

          Fedora 34 has successfully managed to switch over to PipeWire from PulseAudio for its audio needs. Overall, PipeWire is more secure and offers a better audio experience in Fedora 34 than with PulseAudio sound daemon, which was the default in previous Fedora releases.

        • Fedora 34 Releases with GNOME 40, Linux Kernel 5.11, and a New i3 Spin

          After the release of the Fedora 34 beta a week ago, Fedora 34 stable release is finally here with exciting changes and improvements.

          As expected this release of Fedora arrives with the latest Linux kernel 5.11 along with significant changes such as Gnome 40, PipeWire, availability of a Fedora i3 Spin, and various other changes.

          Let’s take a look at the important changes coming to Fedora 34.


          One of the biggest highlights is the arrival of the GNOME 40 desktop. Fedora 34 is one of the few distributions in which you can experience the latest Gnome 40 right now. So, this change is worth noting.

          Taking a look at KDE Plasma, Wayland becomes the default display server for KDE Plasma in Fedora 34. Moreover, KDE Plasma Desktop image is available for AArch64 ARM devices as well.

        • AlmaLinux vs. CentOS Comparison: Is AlmaLinux Up to the Challenge?

          With the announcement from Red Hat that they’re choosing to sunset CentOS and focus on CentOS Stream, many users have been wondering what’s next. The community was able to step in and take over the CentOS legacy in the form of AlmaLinux. Still, this has left many users wondering if AlmaLinux is up to the task. Here we discuss AlmaLinux and CentOS and whether AlmaLinux is up to the challenge of replacing CentOS.

          Red Hat has announced the release of Red Hat Enterprise Linux 8.4, forming the foundation of the company’s new Red Hat Edge Initiative to power the next wave of edge computing.

          Red Hat announced the latest release of its enterprise Linux platform, Red Hat Enterprise Linux (RHEL) 8.4, during this week’s virtual Red Hat Summit.

          RHEL 8.4 furthers the operating system as a foundation for the open hybrid cloud from the data centre to the edge, adding new Linux container, deployment and management capabilities scaled for the needs of edge computing.

          Red Hat's "The State of Enterprise Open Source" research identified 72% of IT leaders expect open source to drive adoption of edge computing over the next two years. The Linux Foundation’s “2021 State of the Edge” report predicts that the Internet of Things (IoT) and edge-related devices will produce around 90 zettabytes of data by 2025.

        • The Mosquito and the Hurricane: Jim Whitehurst on the Past, Present, and Future of IBM

          The modern consumer has taken a much more active role in corporate policy development and direction than in decades past. “Vote with your dollar” campaigns and boycott movements have gone from mosquitoes to hurricanes, forcing dramatic shifts in how investors and corporate executives navigate change and interact with their customers. While social and environmental issues were once considered both opaque and risky, they are now front and center in every conversation about our new digital economy’s future. Though many activist discussions used to be reserved for the camps of Occupy Wall Street, it is clear that a monumental shift has occurred. Impact investing has manifested itself as the logical market response to a rapidly growing cohort of consumers that expect higher ethical standards from the businesses and institutions they support.

          After almost two decades of innovation, seemingly for innovation’s sake, the digitally transformed economy so many yearned for seems to be within reach. Activated like a bolt of lightning by the global pandemic, this transformation reaches further into citizens’ daily lives than anyone, save maybe Orwell, could have ever imagined. Whether or not this new digital economy will serve the best interests of humanity will be a question answered by the actions of citizens and corporations alike. It is no longer a debate; we are living through an era of enlightenment many futurists and forward-looking evangelists have spent decades preparing us for. It is essential to take a moment to recognize this prescience, take a step back, and examine how we got here.

          There aren’t many people more qualified to help the world understand this historical trajectory than Jim Whitehurst, president of IBM, former CEO of Red Hat, and possibly most influential proponent of open-source computing in history. Whitehurst led Red Hat to become the first $1B open-source software company, seven years before being acquired by IBM in 2019 for $34B the single largest acquisition in IBM’s 110-year history.

    • Free, Libre, and Open Source Software

      • Open Source: More Dominant Than You Think

        Though open source has taken over in enterprise networking over the last several years, open source isn’t a new concept. Open source software spun off of the related, but different, free software movement. Richard Stallman, a programmer at MIT’s artificial intelligence lab said he would create a free alternative to the AT&T-owned Unix operating system in 1983.

        Stallman’s alternative was about more than giving away software, it was about giving users the freedom to use, modify, or share the software as they saw fit.

        In September 1983, Stallman launched the GNU Project, in 1985 he started work on the GCC system, and by 1989 the project launched the first General Public License — this license gave users freedom but required them to share modified source code. This requirement to share modified source code is what ultimately allowed free software and open source to take off.

        By the mid 90s, Linux gained popularity and free software was borderline mainstream. In 1997, the essay “The Cathedral and the Bazaar” was published. The essay compared and contrasted the development of Linux and GCC. The principles introduced in the essay would later be central to the DevOps movement. The essay also brought the concept of free software to a broader audience and swayed software executives into trying free software licenses.

        The author of the essay, Eric S. Raymond was pivotal in coining the term open source and the creation of the Open Source Institute. After Netscape released Mozilla’s source code in 1998, Raymond and peers gathered to rebrand free software. Christine Peterson coined the term and Raymond and Bruce Perens started the institute.

        Serving as the foundation of the internet in the 90s, open source became widely used in the 2000s. Open source serves as the foundation for Twitter and Kickstarter, in 2006 companies like eBay and Facebook started contributing to open source software data analyst Hadoop, and in 2008 Google moved open source to your pocket with the release of the Android phone.

          • Phabricator Etiquette Part 2: The Author

            Just as with reviewers, the author is also responsible for making sure the revision is in the appropriate state. As a reminder, ambiguous states happen when the revision needs action from someone, but doesn’t show up in their queue.

            As the author, a common way to get into this predicament is failing to re-request review when no changes are submitted. A typical review might start with the revision in Needs Review (in the reviewer’s queue). The reviewer may request some changes and set it to Needs Revision, which is now back in the author’s queue. The author will then fix the problems and re-submit their patch. Importantly, moz-phab (or maybe Phabricator itself?) will automatically set the state back to Needs Review and all is right with the world.

          • Examining JavaScript Inter-Process Communication in Firefox – Attack & Defense

            Firefox uses Inter-Process Communication (IPC) to implement privilege separation, which makes it an important cornerstone in our security architecture. A previous blog post focused on fuzzing the C++ side of IPC. This blog post will look at IPC in JavaScript, which is used in various parts of the user interface. First, we will briefly revisit the multi-process architecture and upcoming changes for Project Fission, Firefox’ implementation for Site Isolation. We will then move on to examine two different JavaScript patterns for IPC and explain how to invoke them. Using Firefox’s Developer Tools (DevTools), we will be able to debug the browser itself.

            Once equipped with this knowledge, we will revisit a sandbox escape bug that was used in a 0day attack against Coinbase in 2019 and reported as CVE-2019-11708. This 0day-bug has found extensive coverage in blog posts and publicly available exploits. We believe the bug provides a great case study and the underlying techniques will help identify similar issues. Eventually, by finding more sandbox escapes you can help secure hundreds of millions of Firefox users as part of the Firefox Bug Bounty Program.


            In this blog post, we have given an introduction to Firefox IPC using JavaScript and how to debug the child and the parent process using the Content Toolbox and the Browser Toolbox, respectively. Using this setup, you are now able to simulate a fully compromised child process, audit the message passing in source code and analyze the runtime behavior across multiple processes.

            If you are already experienced with Fuzzing and want to analyze how high-level concepts from JavaScript get serialized and deserialized to pass the process boundary, please check our previous blog post on Fuzzing the IPC layer of Firefox.

            If you are interested in testing and analyzing the source code at scale, you might also want to look into the CodeQL databases that we publish for all Firefox releases.

            If you want to know more about how our developers port legacy MessageManager interfaces to JSActors, you can take another look at our JSActors documentation and at how Mike Conley ported the popup blocker in his Joy of Coding live stream Episode 204.

            Finally, we at Mozilla are really interested in the bugs you might find with these techniques – bugs like confused-deputy attacks, where the parent process can be tricked into using its privileges in a way the content process should not be able to (e.g. reading/writing arbitrary files on the filesystem) or UXSS-type attacks, as well as bypasses of exploit mitigations.

          Digital civil society organisations make four demands for a digitally sovereign society to politicians for the 2021 federal election. Among them is the Free Software Foundation Europe, which works to ensure that software developed with public money shall be published under a Free Software licence.

          On 1 April 2020, civil society organisations working for an independent digital infrastructure and free access to knowledge called on politicians: Learn from the crisis - strengthen digital civil society! (German) In an open letter, the undersigned organisations also made concrete recommendations for action. However, far too little has happened since then. The past year has made it clear that politics and public administration are overwhelmed with their own digital transformation and are setting priorities in digital policy that do not meet the needs of society. We are far from a digitally sovereign society.


          At the launch event, Julia Reda (former member of the EU Parliament), Henning Tillmann (software developer and co-chair of D64) and Julia Kloiber (co-founder Superrr Lab) will discuss these four demands on 5 May 2021 from 18:00 to 19:30. The panel will be moderated by Katja Jäger (betterplace lab). Afterwards, all participants will have the opportunity to exchange ideas on solutions, measures and calls for action in four thematic rooms. FSFE's Alexander Sander will moderate the room on "Public Money? Public Code!".

        • CMake Bitrot

          CMake is a (meta-)buildsystem that handles finding-dependencies and building-things. It’s been around for many years, and has been in use by the KDE community for 14 years. In that time, CMake itself has changed quite a bit: there’s “legacy CMake”, version 2.8, and “modern CMake” which is roughly everything after version 3.0. But even within the 3.0 series there is a slow shift in language and tooling. This means that for released software, the CMake buildsystem “bitrots”, to some extent. I’ll give some examples revealed by the CMake 3.20 release.


          Up-to-date software with current releases tends to have fewer issues – even when a change unexpectedly introduces build failures, we can count on the Open Source community to contribute fixes. So GNOME evolution-data-server had fixes in upstream git before I even noticed (and I spotted them only after I’d independently writted roughly-the-same-patch).

          Ancient MySQL releases, on the other hand, need new patches. This can be a somewhat frustrating rabbit hole of building old stuff for no other purpose than fixing the old stuff you don’t use anyway.

          Patches all end up in the FreeBSD ports collection git tree. Search for “CMake 3.20” for the kind of things that needed updating.

SIGUSR1 or SIGUSR2 can be sent to the application to trigger printing of more information.

        • The MIR C interpreter and Just-in-Time (JIT) compiler

          For the past two years I’ve worked on a project implementing a universal lightweight Just-in-Time (JIT) compiler known as MIR. The cornerstone of the project is a machine-independent medium-level intermediate representation (MIR).

          A big part of the project consists of code that compiles C source code into MIR. Because MIR can be interpreted and just-in-timed, I easily extended this C-to-MIR compiler into a C interpreter and JIT compiler.

          I have previously written about other parts of the MIR project (see MIR: A lightweight JIT compiler project, but I never wrote in detail about the C-to-MIR compiler, C interpreter, or JIT. In this article, I would like to correct these omissions.


          Also, I want to extend the C language in the future to mark program points where the C-to-MIR compiler should profile the code and generate speculative and de-optimized code depending on the execution profile. For example, the C code implementing the CRuby virtual machine’s plus bytecode for integers checks the operand types. It also checks that the plus method for integers was not redefined, that there is no overflow, that it doesn’t need to use multi-precision numbers, and so on. All these checks would be the marked program points I am talking about.

          It is hard to implement such extensions for GCC or Clang, get approval to include them into GCC or Clang repositories, or support them on the side.

          So I decided to write my own C-to-MIR compiler first. It should implement standard C11 without rarely used optional standard features such as variable arrays, complex numbers, and atomic data.

          The major implementation goal was simplicity, not compilation speed. This makes studying the code easier for other people and reduces the effort required to maintain it.

          Ruby’s IRB is a lovely interactive console. By leveraging a custom .irbrc configuration file, we can make the experience even better.

          The .irbrc file is nothing else than a Ruby file that gets evaluated whenever we start the console with irb or rails c. We can place it in a home directory (~/.irbrc) or in the project directory (to scope it per project). But only one of these files will take effect, and the global one has precedence.

            A returning question I get is: “I see, that you can send alerts from syslog-ng to Slack and Telegram, but do you happen to support XYZ?” Replace XYZ with Discord and countless others. So, last week I showed you how to send alerts to Discord using the http() destination of syslog-ng and introduced you to Apprise, a notification library for Python.

            From this blog, you can learn how to make your syslog-ng destination developed in Python more flexible using templates, and how to make it easier to use with using blocks. We use the Apprise notification library again. On the feature side, the Python code is a lot closer to being production ready. It has most features a user would want to use. Still, it is rather just an inspiration, not something production ready, as among others, it is missing error handling and reporting.

            Fedora 34, a feature-packed new release of Red Hat's leading edge Linux distribution, was released today, though the main Java package maintainer has quit, urging "affected maintainers to drop dependencies on Java."

            Fedora 34 is used by Red Hat to try out new features that are likely to end up in first CentOS Stream and then Red Hat Enterprise Linux (RHEL), the commercial offering.


            Spoiling the celebrations, Fedora's main Java package maintainer Fabio Valentini said yesterday: "I can no longer in good conscience be the primary maintainer of (most) Java packages in Fedora."

            It is worse than that; in a post entitled "The Death of Java (packages)" he said "new versions and even security issues have been piling up for months," that "Java package maintainers from Red Hat have been exceptionally unhelpful, and have not substantially contributed to Java packages in Fedora in years," that the Eclipse Java-based IDE (the packages for which are maintained by someone else) is a "dumpster fire" and that "I see no way for the situation to improve."

            Valentini decided to orphan "all Java packages I am the main admin of" adding that "since this is the majority of remaining Java software in Fedora … I expect a decent amount of dependent packages will be affected." His solution is to "urge affected maintainers to drop dependencies on Java, if at all possible."

      • How automation can transform storage provisioning

        The diversity of systems and software running business operations has increased to the point where managing all the components can consume most of a data center teams’ energy, taking precious time away from planning and implementing new initiatives that move an agency’s mission forward.

        To ease the burden on team bandwidth, data center leaders frequently rely on monitoring software that continually checks for system faults and outages so operations don’t fail. That’s useful for meeting uptime and data protection service level agreements (SLAs). However, it still doesn’t provide real-time monitoring that can ensure systems and software are optimized both individually and holistically. That optimization should cover adjusting applications, hypervisor, servers, networks and storage for peak performance and uptime.

      • Artificial Intelligence Is Misreading Human Emotion [Ed: Can we quit calling every computer and computer program "hey hi"?]

        At a remote outpost in the mountainous highlands of Papua New Guinea, a young American psychologist named Paul Ekman arrived with a collection of flash cards and a new theory. It was 1967, and Ekman had heard that the Fore people of Okapa were so isolated from the wider world that they would be his ideal test subjects.

        Like Western researchers before him, Ekman had come to Papua New Guinea to extract data from the indigenous community. He was gathering evidence to bolster a controversial hypothesis: that all humans exhibit a small number of universal emotions, or affects, that are innate and the same all over the world. For more than half a century, this claim has remained contentious, disputed among psychologists, anthropologists, and technologists. Nonetheless, it became a seed for a growing market that will be worth an estimated $56 billion by 2024. This is the story of how affect recognition came to be part of the artificial-intelligence industry, and the problems that presents.

              • How To Get A University Banned From The Linux Kernel

                Once again the Linux kernel was in the news and not for anything good, but they weren't the cause, the cause was a certain University, the University of Minnesota that allowed for a fairly questionable study to take place of the course of the previous year.

              • Minnesota University Apologizes for Contributing Malicious Code to the Linux Project

                Researchers from the University of Minnesota apologized to the maintainers of Linux Kernel Project on Saturday for intentionally including vulnerabilities in the project's code, which led to the school being banned from contributing to the open-source project in the future.

                "While our goal was to improve the security of Linux, we now understand that it was hurtful to the community to make it a subject of our research, and to waste its effort reviewing these patches without its knowledge or permission," assistant professor Kangjie Lu, along with graduate students Qiushi Wu and Aditya Pakki, said in an email.

                "We did that because we knew we could not ask the maintainers of Linux for permission, or they would be on the lookout for the hypocrite patches," they added.

              • University of Minnesota responds to Linux security patch requests

                If you're just catching up on this story, here's the quick recap: University of Minnesota researchers deliberately submitted patches that would have put the Use-After-Free (UAF) vulnerability into the Linux kernel. When it appeared they were trying once more to put garbage patches into the kernel, Greg Kroah-Hartman, the Linux kernel maintainer for the stable branch, banned UMN developers from submitting to the kernel and pulled existing suspicious UMN patches. The Linux Foundation followed up with a list of requests for the UMN to comply with if they wanted to work with the Linux kernel again. Now, ZDNet has obtained a copy of UMN's response to the Linux community.

              • University Of Minnesota Apologizes To Unwavering Linux Community Over Kernel Kerfuffle

                Last week, we reported on a Linux Kernel developer banned The University of Minnesota for some ethically questionable research. Since then, UMN issued an apology and started an investigation into how this all happened, but some people are having none of it. This week in the Linux Kernel security saga, Greg Kroah-Hartman announced that the Linux Foundation and its Technical Advisory Board sent a letter to UMN outlining what must be done to regain the trust of the Linux community, and no further discussion will be had.

                Earlier this year, three researchers from UMN published a paper that proved that vulnerabilities could be slipped past Linux Kernel maintainers. The team used three easily fixed bugs in the Linux kernel, which all had the trappings of becoming a vulnerability, and submitted them to see if the maintainers detected a problem. Once the maintainers replied to the patch, the UMN researchers explained the bug and gave an actual patch instead of the one originally submitted.

              • The Linux Foundation Has a Few Demands for Banned University

                The researchers who got the University of Minnesota (UMN) banned from contributing to the Linux kernel are going to have to do more than apologize for their actions. ZDNet reported that the Linux Foundation’s Technical Advisory board sent a list of demands the university will have to meet before it can seek forgiveness.

                A quick recap: UMN researchers contributed intentionally flawed code to the Linux kernel in August 2020 for a paper on these so-called “hypocrite commits” that was published in February. A separate project meant to “automatically identify bugs introduced by other patches” then drew the ire of Greg Kroah-Hartman, the developer who oversees the Linux kernel’s stable release channel last week.

                Kroah-Hartman banned the entire UMN system from contributing to the Linux kernel as a result of the research projects. That decision was followed by an apology from the UMN Department of Computer Science and Engineering (CSE), a significant amount of discussion amongst the Linux community, and then a separate apology from the faculty and students who actually conducted the controversial research.

              • Linux kernel security uproar: What some people missed

                Recently the Linux kernel community was aflame due to efforts by researchers at the University of Minnesota to intentionally torpedo Linux security by submitting faulty patches. While the University's Department of Computer Science apologized, the damage was done, and Linux kernel maintainer Greg Kroah-Hartman banned the University from contributing to the kernel.

                However you feel about what these researchers did (Chris Gaun, for example, argued, "A researcher showed how vulnerabilities can EASILY make it through [the] approval process"), this isn't really about Linux, or open source, security. It's always been the case that it's possible to get bad code into good open source projects. Open source software isn't inherently secure. Rather, it's the open source process that is secure, and while that process kicks in during development, it's arguably most potent after vulnerabilities are discovered.

          • SniperPhish: An all-in-one open-source phishing toolkit

            “The idea to develop SniperPhish came to me in a period during which the company I previously worked with did many social engineering assessments. Most of the assessment included phishing campaigns, which means creating and hosting phishing websites and crafting email campaigns. The available tools had certain limitations and were not very effective at simultaneously tracking data from the phishing emails and websites,” security consultant Gem George, the tool’s creator, told Help Net Security.

            “For example, the client didn’t want us to capture the users’ passwords that were submitted to the phishing website. For each project, we were required to code for tracking data from phishing websites. Additionally, the data captured from this website needed to be mapped to the mail campaign, which was a time-consuming and often resulted in errors.”

          • Linux Kernel Bug Opens Door to Wider Cyberattacks

            The information-disclosure flaw allows KASLR bypass and the discovery of additional, unpatched vulnerabilities in ARM devices.

            An information-disclosure security vulnerability has been discovered in the Linux kernel, which can be exploited to expose information in the kernel stack memory of vulnerable devices.

            Specifically, the bug (CVE-2020-28588) exists in the /proc/pid/syscall functionality of 32-bit ARM devices running Linux, according to Cisco Talos, which discovered the vulnerability. It arises from an improper conversion of numeric values when reading the file.

          The number of patents for inventions related to low-carbon energy technologies around the world grew by an average rate of 3.3% per year in the 2017-19 period, a new joint study published today by the European Patent Office (EPO) and the International Energy Agency (IEA) shows.

          The European Patent Office (EPO) has adopted a new environmental policy that outlines its plan to be carbon neutral by 2030. The policy will serve as an agreed framework that outlines the Office's overall strategy and defines measurable objectives. The EPO recognises that as a large employer with sites across Europe, it has a responsibility to contribute to environmental efforts at local and global levels.

        • How patents transformed the world of architecture

          People widely describe architecture as a meeting of science and art, says associate professor of art history Peter Christensen at the University of Rochester. But his latest project, still in the early phases of research, aims to look at that characterization in detail. He’s using the measure of patents and patentability in the history of architecture to tease apart the distinctions people have made between technology and art—and to see how architectural “authorship” has functioned.


          “The Architectural Patent” will be Christensen’s third sole-authored book, following on Germany and the Ottoman Railways: Art, Empire, and Infrastructure (Yale University Press, 2017) and “Materialized: German Steel in Global Ecology” (currently in production at Penn State Press).

          When the pandemic lifts and he can travel safely again, he plans to visit major European archives, including the European Patent Office in Munich, the National Archives in the UK and the National Archives in Paris, to carry out some of his research.

          Christensen is excited that his newest work will take him in a new direction as a scholar. Rather than drilling down into a highly specialized topic, as he did in his first two books, Christensen sees his latest work, with his exploration of authorship as it pertains to architecture, as an opportunity to make a broader—or what he calls a more “horizontal”—contribution to the field of art history.
