Security Patches in OpenSUSE and SUSE

Security
SUSE
  • Two Tumbleweed Snapshots update PostgreSQL, Mesa

    Snapshot 20201117 provides the latest update of packages for the rolling release. Among the packages to update was Mozilla Thunderbird to version 78.4.3; the email client updated a Rust patch and brought in a new feature from a previous minor version that prompts for an address to be used when starting an email from an address book entry with multiple addresses. KDE’s Plasma 5.20.3 stopped the loading of multiple versions of the same plugin in the task manager KSysGuard and there were many other bug fixes for Plasma users. Four months of shell scripts were updated in the hxtools 20201116 version; one of the changes to gpsh changed the tmp location to /var/tmp, which was to avoid saving potentially large files to tmpfs. The Linux Kernel made a jump from 5.9.1 to 5.9.8, which had a change for Btrfs as well as several USB changes. Database package postgresql 13 had its first point release to 13.1, which took care of three Common Vulnerabilities and Exposures and fixed a time test case so it works when the USA is not observing daylight-savings time. The graphical tool for administering virtual machines, virt-manager slimmed down the filesystem device editor User Interface. Text editor vim had a fix for when a crash happens when using a popup window with “latin1” encoding and python 3.8.6 took care of CVE-2019-20916.

  • SolidRun launches i.MX 8M Plus SOM and devkit for AI/ML applications

    SolidRun already offers NXP based solutions with AI accelerators through products such as SolidRun i.MX 8M Mini SoM with Gyrfalcon Lightspeeur 2803S AI accelerator, or Janux GS31 Edge AI server with NXP LX2160A networking SoC, various i.MX 8M SoCs and up to 128 Gyrfalcon accelerators.

    All those solutions are based on one or more external Gyrfalcon AI chips, but earlier this year, NXP introduced i.MX 8M Plus SoC with a built-in 2.3 TOPS neural processing unit (NPU), and now SolidRun has just unveiled the SolidRun i.MX 8M Plus SoM with the processor together with development kits based on HummingBoard carrier boards.

  • SolidRun takes on Google's Raspberry Pi-like computer

    Israeli edge-computing outfit SolidRun has launched a new lineup of Raspberry Pi-like computers based on NXP's new i.MX 8M Plus application processor.

    SolidRun makes edge computing kit containing Arm-based and Intel chips. Earlier this year, it teamed up with application-specific integrated circuit (ASIC) chip manufacturer Gyrfalcon Technology to build the Arm-based, Linux Janux GS31 AI inference server.

  • Linux Syscall User Dispatch Close To Mainline For Better Handling Windows Games - Phoronix

    Earlier this year we reported on Linux kernel work for better handling Windows games/apps that make system call instructions that bypass the Windows API. Directly making the system calls without going through the WinAPI has become an increasingly common occurrence for modern Windows games, likely as part of their Digital Rights Management schemes. Syscall User Dispatch is now the latest take on that effort.

    The syscall user redirection support has been led by Collabora engineers working in cooperation with Valve. That work evolved into the "Syscall User Dispatch" feature that is now up to its seventh code revision and likely soon to be mainlined in the Linux kernel.

  • Collabora put up their patches for Linux Kernel work to help Windows games on Linux | GamingOnLinux

    Collabora, one of the companies working under contract for Valve to help improve Windows game emulation on Linux with the likes of Wine have now sent in some patches to the Linux Kernel mailing list for discussion.

    This is going to be another big step forward for compatibility, hopefully, to help with the likes of anti-tamper and DRM which often skip over the Windows API which causes issues for Linux and the Wine compatibility layer (and so Steam Play Proton too). You can get an overview of it in this previous article and also this article if you want some background on it all. To be clear: a Valve developer did mention it's not for anti-cheat.

  • Civilization VI - Babylon Pack is out now with the 'Heroes and Legends' mode | GamingOnLinux

    Civilization VI has a new DLC out with the Babylon Pack, part of the ongoing New Frontier Pass or you can buy it as a single DLC if you prefer. This brand new DLC follows on from the surprisingly fun free Pirates game mode update, that Firaxis Games released for everyone back in late October.

    This new content pack introduces Hammurabi as the leader of Babylon. The Babylon civilization excels at Science, as well as Government and Infrastructure. Additionally, it also brings with it a "Heroes and Legends" game mode which adds in legendary figures from various cultures as playable characters on the world.

  • Total War: WARHAMMER II – The Twisted & The Twilight announced for December | GamingOnLinux

    Total War: WARHAMMER II – The Twisted & The Twilight is the next expansion for the huge strategy game from Creative Assembly, SEGA and porting studio Feral Interactive. Arriving for Windows on December 3, Feral Interactive have confirmed that it will arrive on Linux (and macOS) "shortly" after Windows. This could be anything from a day to a few weeks, hopefully not long though.

    This Lords Pack for Total War: WARHAMMER II introduces two new Legendary lords for the Skaven and the Wood Elves. Each leads their own faction and features new characters, units, unique gameplay mechanics and narrative objectives.

  • Tenderfoot Tactics sold well enough to fund another game, more updates coming | GamingOnLinux

    Tenderfoot Tactics is probably one of the best games released this year. An open-world tactics RPG that mixed real-time exploration and turn-based tactical battles, with a really gorgeous simple visual style with bright colours.

    Badru, one of the team responsible for creating it mentioned in a recent update that they're working on another tactics RPG. This is because sales of Tenderfoot Tactics "are good enough that I'm likely going to be able to self-fund another game". Work hasn't stopped on Tenderfoot though, far from it.

  • Pharaoh-like isometric city builder Nebuchadnezzar to release February 17, 2021 | GamingOnLinux

    Nebuchadnezzar has been announced for release on February 17, 2021 and it will be coming with full Linux support from Nepos Games. If you love city-builders, you're going to want to take a look at this. In it you will experience "the mysterious history and culture of ancient Mesopotamia" with a campaign that has you rule over influential historical cities filled with complex monuments.

Qt and Qt Creator Releases

Development

  • Qt 5.15.2 Released

    We have released Qt 5.15.2 today. As a patch release, Qt 5.15.2 does not add any new functionality but provides bug fixes.

    Compared to Qt 5.15.1, the new Qt 5.15.2 contains 176 bug fixes.  For details of the most important changes, please check the Change files of Qt 5.15.2.

    Qt 5.15.2 can be installed by using the maintenance tool. Note that we have recently released new version of the installer, so unless you already have updated to it, you need to run the installer update first . 

  • Qt 5.15.2 Released With Another 176 Bug Fixes - Phoronix

    Two months ago Qt 5.15.1 released with over 400 bug fixes and today the second point release of Qt 5.15 LTS is out with another nearly two hundred fixes. 

    While all eyes are on Qt 6.0 that should be shipping in December, Qt 5.15 is very important considering it's a long-term support (LTS) release where as Qt6 won't be seeing an LTS release for another year until Qt 6.2. There were tons of fixes poured into Qt 5.15.1 and it remains that way with the newly minted Qt 5.15.2 LTS. 

  • Qt Creator 4.13.3 released

    We are happy to announce the release of Qt Creator 4.13.3 !

    For this release we updated the prebuilt binaries to Qt 5.15.2, which fixes drag & drop on macOS. Please see our change log for an overview of the other improvements.

  • Qt Creator 4.14 Beta2 released

    We are happy to announce the release of Qt Creator 4.14 Beta2 !

  • How To Install FTP Server on Linux Mint 20 - idroot

    In this tutorial, we will show you how to install FTP Server on Linux Mint 20. For those of you who didn’t know, FTP stands for “file transfer protocol”, and it allows you to transfer files to a remote computer. The most common FTP server software for Ubuntu is the vsftpd package, which stands for “very secure FTP daemon.” It’s the default FTP package for Ubuntu, and most other Linux distributions as well.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation of FTP Server on a Linux Mint 20 (Ulyana).

How we develop success metrics for open source events

Filed under
OSS

As many open source communities grow larger and older, they may face problems managing members' engagement. People turn towards metrics to understand large systems and prioritize resources, but there has not been a consensus set of metrics for understanding open source communities.

The Community Health Analytics Open Source Software (CHAOSS) project, a Linux Foundation-sponsored community of industry professionals and academics, is working to solve this problem by defining metrics for open source projects. The CHAOSS project focused first on developing metrics for open source event organizers because open source communities often depend on events like hackathons, meetups, conferences, and user group meetings to grow their communities and work on important project updates.

What do open source product teams do?

Filed under
OSS

If you go to any hip product management conference, you'll hear about product teams. At a minimum, a product team has a product manager, but it often includes roles in marketing, technical architecture, and even user experience (UX). Previous articles in this series have covered open source as a supply chain model and defining products in the open source software supply chain, and this article specifically focuses on the role of product management within the product team.

Product managers and product marketing managers are the two most common product management roles, but product management can be further split into any number of roles, including competitive analysis, business strategy, sales enablement, revenue growth, content creation, sales tools, and more. With a very large product, even the product management role may be broken up into separate roles. You may even hear titles like technical marketing manager, product evangelist, and business owner, not to mention people-management roles for groups of individual contributor roles. For the purpose of this article, I refer to all of these roles collectively as "product management."

  • Intel Preparing To Restore Frame-Buffer Compression For Tiger Lake - Phoronix

    This summer Intel disabled frame-buffer compression for Gen12 Tiger Lake graphics. While FBC helps conserve memory bandwidth and can be beneficial to power-savings, under-run issues and related problems resorted Intel to disabling this common feature for Tiger Lake.

    But now the open-source Intel Linux developers are preparing to restore frame-buffer compression for benefiting these latest-generation Intel laptops. Well, at least in part.

  • Robert O'Callahan: Debugging With Screenshots In Pernosco

    When debugging graphical applications it can be helpful to see what the application had on screen at a given point in time. A while back we added this feature to Pernosco.

    This is nontrivial because in most record-and-replay debuggers the state of the display (e.g., the framebuffer) is not explicitly recorded. In rr for example, a typical application displays content by sending data to an X11 server, but the X11 server is not part of the recording.

    Pernosco analyzes the data sent to the X11 server and reconstructs the updates to window state. Currently it only works for simple bitmap copies, but that's enough for Firefox, Chrome and many other modern applications, because the more complicated X drawing primitives aren't suitable for those applications and they do their complex drawing internally.

  • Paalanen: Developing Wayland Color Management and High Dynamic Range [LWN.net]

    Over on the Collabora blog, Pekka Paalanen writes about adding color management and high dynamic range (HDR) support to the Wayland display server protocol.

  • Developing Wayland Color Management and High Dynamic Range

    Wayland (the protocol and architecture) is still lacking proper consideration for color management. Wayland also lacks support for high dynamic range (HDR) imagery which has been around in movie and broadcasting industry for a while now (e.g. Netflix HDR UI).

    While there are well established tools and workflows for how to do color management on X11, even X11 has not gained support for HDR. There were plans for it (Alex Goins, DeepColor Visuals), but as far as I know nothing really materialized from them. Right now, the only way to watch HDR content on a HDR monitor in Linux is to use the DRM KMS API directly, in other words, not use any window system, which means not using any desktop environment. Kodi is one of the very few applications that can do this at all.

    This is a story about starting the efforts to fix the situation on Wayland.

  • Acer Aspire Switch 10 E SW3-016's (and SW5-012's) horrible EFI firmware

    Depending on what OS the BIOS thinks it is booting it renames one of these 2 to _HID. This is weird given that it will only boot if EFI/Microsoft/Boot/bootmgfw.efi exists, but it still does this. Worse it looks at the actual contents of EFI/Boot/bootx64.efi for this. It seems that that file must be signed, otherwise it goes in OS unknown mode and keeps the 2 above DSDT bits as is, so there is no _HID defined for the wifi's mmc controller and thus no wifi. I hit this issue when I replaced EFI/Boot/bootx64.efi with grubx64.efi to break the bootloop. grubx64.efi is not signed so the DSDT as Linux saw it contained the above AML code.

A Review of NixOS

Filed under
Reviews

Most reviews go over desktop tools and default tools, but such reviews are not very useful for describing NixOS, as the power of NixOS lies elsewhere. People who choose NixOS must be willing to do their own partitioning, and you will not be doing them any favours by telling them the default desktop manager can suit their needs.

With that said, if you can follow the NixOS manual, you will be fine. You can choose a default desktop environment if you want, but make sure you are comfortable with the command line and can edit a text file for configuration tasks.

  • How to Secure the SSH Server in Ubuntu 20.04 from Basic to Advanced – Linux Hint

    Just like all other servers, the SSH server is also prone to unauthorized access attempts. Therefore, whenever you wish to use an SSH server, you must have considered securing it first to save yourselves from any unwanted situation in the longer run. Generally, the term “securing a server” is also known as “hardening a server.” This can be done by taking multiple measures. These measures depend upon the level of security that you require.
    The measures of securing the SSH server range from basic to advanced, and as we said earlier, you can pick them up according to the level of security that you need. You can skip any of the prescribed measures if you have sufficient knowledge about the consequences and if you are in a good position to face them. Also, we can never say that a single step will ensure 100% security, or a certain step is better than the other.

    It all depends upon which type of security we actually need. Therefore, today we intend to give you a very deep insight into the basic and advanced steps for securing an SSH server in Ubuntu 20.04. Apart from these methods, we will also be sharing with you some additional tips for securing your SSH server as a bonus. So let us get started with today’s interesting discussion.

  • Sebastian Kügler: Bringing light to life

    Some of you may be wondering what I have been up to lately since I took a break from my work in the KDE community. Well, it was time for a change, a change towards family, friends and a more local life. The result is a more balanced, a more grown up me. These changes in my life lead to me having a small family and a group of new friends, both of which I spend a lot of time with. They brought more light into my life, one could say.

  • If you want to go far, together is faster (II).

    If you work in an environment where Continuous Delivery is the norm, those behind the execution will understand which actions have a positive correlation between throughput and stability. Your job will only be associated to link those actions with the ones you are familiar with in the community health and collaboration space. If not, you work will be harder, but still worth it.

    For our particular case, you might find for instance, that a simple measure to digest the increasing number of commits (bug fixes) can be to scale up the build capacity if you have remaining budget. You might find though that you have problems doing so when reviewing acceptance criteria because you lack automation, or that your current testing-on-hardware capacity is almost fixed due to limitations in the system that manage your test benches and additional effort to improve the situation is required.

    Establishing experiments that consider not just the collaboration side but also the software delivery one as well as translating into production those experiments that demonstrate a positive correlation of the target metrics, increasing all of them, might bring you to surprising results, sometimes far from common knowledge among those focused on collaboration aspects only, but closer to those focused in execution.

  • OSI Seeks to Hire Executive Director [Ed: More evidence that the Open Source Initiative is collapsing after Microsoft took over much of it.]

    It is with great pride and excitement that I announce that OSI, as of today, is embarking on a search for an Executive Director.

    This is the culmination of many years of work and dedication on the part of countless individuals, and should be taken as a sign that OSI is maturing as an organization. We are following in the footsteps of many organizations that have come before us: nonprofits often start as a scrappy band of volunteers, which then hire staff for day-to-day operations, and eventually the staff are empowered to lead the organization.

  • Transparency

    Technology must be transparent in order to be knowable. Technology must be knowable in order for us to be able to consent to it in good faith. Good faith informed consent is necessary to preserving our (digital) autonomy.

    Let’s now look at this in reverse, considering first why informed consent is necessary to our digital autonomy.

    Let’s take the concept of our digital autonomy as being one of the highest goods. It is necessary to preserve and respect the value of each individual, and the collectives we choose to form. It is a right to which we are entitled by our very nature, and a prerequisite for building the lives we want, that fulfill us. This is something that we have generally agreed on as important or even sacred. Our autonomy, in whatever form it takes, in whatever part of our life it governs, is necessary and must be protected.

    [...]

    As long as the source code that powers computing technology is proprietary and opaque, we cannot truly know whether backdoors exist and how secure we are in our digital spaces and even our own computers, phones, and other mobile devices.

    NEWS
    
    * New features added
    
      - In the testsuite summary, the "for $(PACKAGE_STRING)" suffix
        can be overridden with the AM_TESTSUITE_SUMMARY_HEADER variable.
    
    * Bugs fixed
    
      - Python 3.10 version number no longer considered to be 3.1.
    
      - Broken links in manual fixed or removed, and new script
        contrib/checklinkx (a small modification of W3C checklink) added,
        with accompany target checklinkx to recheck urls.
    
      - install-exec target depends on $(BUILT_SOURCES).
    
      - valac argument matching more precise, to avoid garbage in DIST_COMMON.
    
      - Support for Vala in VPATH builds fixed so that both freshly-generated and
        distributed C files work, and operation is more reliable with or without
        an installed valac.
    
      - Dejagnu doesn't break on directories containing spaces.
    
    * Distribution
    
      - new variable AM_DISTCHECK_DVI_TARGET, to allow overriding the
        "make dvi" that is done as part of distcheck.
    
    * Miscellaneous changes
    
      - install-sh tweaks:
        . new option -p to preserve mtime, i.e., invoke cp -p.
        . new option -S SUFFIX to attempt backup files using SUFFIX.
        . no longer unconditionally uses -f when rm is overridden by RMPROG.
        . does not chown existing directories.
    
      - Removed function up_to_date_p in lib/Automake/FileUtils.pm.
        We believe this function is completely unused.
    
      - Support for in-tree Vala libraries improved.
    
    
  • TOP500 Expands Exaflops Capacity Amidst Low Turnover

    The 56th edition of the TOP500 saw the Japanese Fugaku supercomputer solidify its number one status in a list that reflects a flattening performance growth curve. Although two new systems managed to make it into the top 10, the full list recorded the smallest number of new entries since the project began in 1993.

    The entry level to the list moved up to 1.32 petaflops on the High Performance Linpack (HPL) benchmark, a small increase from 1.23 petaflops recorded in the June 2020 rankings. In a similar vein, the aggregate performance of all 500 systems grew from 2.22 exaflops in June to just 2.43 exaflops on the latest list. Likewise, average concurrency per system barely increased at all, growing from 145,363 cores six months ago to 145,465 cores in the current list.

  • Daniel Silverstone: Withdrawing Gitano from support

    Unfortunately, in Debian in particular, libgit2 is undergoing a transition which is blocked by gall. Despite having had over a month to deal with this, I've not managed to summon the tuits to update Gall to the new libgit2 which means, nominally, I ought to withdraw it from testing and possibly even from unstable given that I'm not really prepared to look after Gitano and friends in Debian any longer.

  • The 20 Best Scala Books For Beginner and Expert Developers

    Scala is an elevated level language that joins object-oriented and practical programming in one succinct. Certain static kinds of Scala help us dodge bugs in complex applications; moreover, its JVM, and JavaScript runtimes let us manufacture elite frameworks with simple admittance to colossal biological systems libraries. In the field of software, Scala is a very unique and multidimensional language. To learn Scala programming is not an easy job for someone new to this field, and therefore, a perfect set of Scala books is inevitably important for accurate guidance.

  • Comparing a new language for tiny machines

    Upstream seemed surprised that I was writing real programs in Cowgol, so I'm led to believe I might be the only one using the language. But that's fine. Let's write a simple program in C and in Cowgol so that we can compare them. Even if you're not going to use Cowgol, comparing programming languages I find to be a fun exercise and it might help you think about your own language choices, no matter what languages you choose to use.

  • How to Install and Use FFmpeg in CentOS 8? – Linux Hint

    If you’d like a fast way of converting between audio and video files in Linux and would like something that doesn’t chew on resources and does the task properly, then you may give FFmpeg a try. FFmpeg is vital for keeping some level of familiarity between files uploaded by multiple users, as well as help maintain your storage space under control. When using FFmpeg, you can translate, adjust sample rates, record audio/video streams, and resize files between different video and audio formats. It provides a collection of audio and video libraries that are shared, including libavcodec, libavformat, and libavutil. Whenever it refers to converting files, FFmpeg has several command-line choices, and it is also recommended to use it from the CLI. Follow me on, and I’ll lead you to install FFmpeg in Centos 8. FFmpeg is not offered in the default repositories of Centos 8. You may opt to build FFmpeg utilities from the source or install them from the Negativo17 directory via DNF. In this article, we’ll move ahead with the second choice. It is also the fastest way to implement FFmpeg on the Centos 8 OS.

  • How to Kill Zombie Processes on Linux

    Linux, of course, has to keep track of all the applications and daemons running on your computer. One of the ways it does this is by maintaining the process table. This is a list of structures in kernel memory. Each process has an entry in this list that contains some information about it. There isn’t a great deal in each of the process table structures. They hold the process ID, a few other data items, and a pointer to the process control block (PCB) for that process. It’s the PCB that holds the many details Linux needs to look up or set for each process. The PCB is also updated as a process is created, given processing time, and finally destroyed.

  • How to Use arping Command in Linux – Linux Hint

    To a network administrator, the ARP protocol may sound familiar. ARP is a protocol that Layer 2 devices implement for discovering and communicating with each other. The arping tool works using this protocol. Now, why would you need arping? Imagine you are working with a small office network. Using the classic ping command to ping hosts to verify their availability is very tempting, right? Well, if you are using the ICMP protocol, then you are actually performing ARP requests for probing devices in the network. This is where the arping tool comes in. Like ping, arping pings network hosts using network layer ARP packets. This method is useful for hosts that do not respond to Layer 3 and Layer 4 ping requests. This article shows you how to use arping command in Linux.

  • How to configure YAML schema to make editing files easier - Red Hat Developer

    YAML is a friendly data serialization standard that works with all programming languages. While configuration files are often defined in YAML, it can even be used as a programming language, like the workflow language at Google, or Apache Camel K. It has the advantage of not having any braces, making it lightweight visually. One of the drawbacks is that editing YAML files may not always be easy. For instance, writing a tag at the wrong indentation level can be hard to detect. To help with editing, it is possible to provide a YAML schema that can be leveraged by a large set of integrated development environments (IDEs). Unfortunately, this practice is not widespread. Consequently, users waste time searching for a missing or extra space and browsing documentation. In this article, you will discover the benefits of providing a YAML schema and how to make it consumable for all your users, making it easier to edit YAML files.

  • How to connect and share data between two Linux systems

    I got an interesting request (not from singles in my area). One of my readers asked me, how does one go about connecting two Linux boxes - I presume for sharing purposes. This is a topic I've touched upon frequently, but often indirectly. As Commandant Lasard from Police Academy would say, there are many, many, many, many different ways to do this. So perhaps it's time for a proper tutorial. I will show you several common, robust ways to have two Linux systems communicate over network. We'll do it on the command line, then move up to file managers, and finally, also perform a remote data backup using a friendly GUI tool. Let's start.
