  • The Best Features Of The Linux 4.18 Kernel

    Following a one week delay, the Linux 4.18 kernel is set to be released this coming weekend. In case you forgot about the new features and improvements since the Linux 4.18 cycle kicked off back in June, here's a look back at some of the most prominent additions for this latest kernel version.

  • Linux kernel bug: TCP flaw lets remote attackers stall devices with tiny DoS attack

    Security researchers are warning Linux system users of a bug in the Linux kernel version 4.9 and up that could be used to hit systems with a denial-of-service attack on networking kit.

    The warning comes from Carnegie Mellon University's CERT/CC, which notes that newer versions of the Linux kernel can be "forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service (DoS)".

  • Speck Crypto Code Called For Removal From The Linux Kernel

    Now that Google will not be using the Speck crypto code for disk encryption on low-end Android devices but instead developing "HPolyC" as outlined in the aforelinked article, a plea has already been submitted to remove the current Speck code from the mainline Linux kernel.

    Following yesterday's mailing list announcement that Google has changed its mind on using Speck and instead investing in a new option, Linux developer Jason Donenfeld took the liberty of issuing a "request for comments" on removing the Speck crypto code. Donenfeld is the developer that's been working on WireGuard and the new Zinc crypto library.

Graphics: Freedreno Gallium3D and NVIDIA

  • Freedreno Gallium3D Lands MSAA Support For Qualcomm Adreno 600 Series
    While Qualcomm was busy hosting their Tech Summit this week in Hawaii, the independent open-source developers were pressing ahead with their reverse-engineered Qualcomm Adreno 3D graphics driver support. Rob Clark of Red Hat and Kristian Kristensen of Google landed their latest Freedreno Gallium3D driver improvements into Mesa 19.0. The most notable addition was multi-sample anti-aliasing support (MSAA) for the Adreno 600 series hardware. There is also now EXT_multisampled_render_to_texture support exposed by this Gallium3D driver. Besides that work there were also fixes and other changes.
  • NVIDIA Tegra X2 & Xavier Get HDMI Audio With Linux 4.21
    While it's not as exciting as if seeing full 3D open-source driver support, with the upcoming Linux 4.21 kernel are some mainline Tegra improvements that does include HDMI audio support for the X2 and Xavier SoCs. Thierry Reding of NVIDIA sent in the Tegra DRM driver updates this week for the upcoming Linux 4.21 cycle. He commented, "These changes contain a couple of minor fixes for host1x and the Falcon library in Tegra DRM. There are also a couple of missing pieces that finally enable support for host1x, VIC and display on Tegra194. I've also added a patch that enables audio over HDMI using the SOR which has been tested, and works, on both Tegra186 and Tegra194."

Powers of two, powers of Linux: 2048 at the command line

Hello and welcome to today's installment of the Linux command-line toys advent calendar. Every day, we look at a different toy for your terminal: it could be a game or any simple diversion that helps you have fun. Maybe you have seen various selections from our calendar before, but we hope there’s at least one new thing for everyone. Today's toy is a command-line version of one of my all-time favorite casual games, 2048 (which itself is a clone of another clone). Read more

More Radeon RX 590 Ubuntu Benchmarks - See How Your Linux GPU Performance Compares

Published on Friday was my Radeon RX 590 Linux benchmarks now that the kinks in the support for this latest Polaris refresh are worked out (at least in patch form). Here are some complementary data points with some of the OpenGL tests outside of the Steam games for those curious about the RX 590 performance in other workloads or wanting to see how your own GPU performance would compare to these results. The Radeon RX 590 continues running well with the patched Linux 4.20 kernel build (hopefully the last patch needed for the RX 590 will make it into 4.20 mainline soon) and in user-space was Mesa 19.0 from the Padoka PPA for this system running on Ubuntu 18.04 LTS.
