TuxMachines: Linux Kernel Developer: Steven Rostedt

Thursday 5th of April 2018 04:39:17 PM

Linus Torvalds recently released version 4.16 of the Linux kernel. These releases typically occur every nine to ten weeks, and each one contains the work of more than 1,600 developers representing over 200 corporations, according to the 2017 Linux Kernel Development Report, written by Jonathan Corbet and Greg Kroah-Hartman. In this series, we’re highlighting some of the developers who contribute to the kernel.

Steven Rostedt, Open Source Programmer at VMware, maintains the Real Time Stable releases of the Linux kernel, among other things. Rostedt is one of the original developers of the PREEMPT_RT patch and began working on it in 2004 with the goal of turning Linux into a real-time designed operating system. He is also the main author, developer, and maintainer of Ftrace, a tool designed to help developers find what is going on inside the kernel. According to the Ftrace wiki, the tool can be used for debugging or analyzing latencies and performance issues that take place outside of user-space.

TuxMachines: Security: Intel Lockout/Lockdown, Windows Issues

Thursday 5th of April 2018 03:27:23 PM
  • Security updates for Thursday
  • Intel won't be patching the Spectre V2 flaw in its older chips any time soon

    Intel might not be able to fix the second version of the Spectre flaw that affects more than 230 models of its processors, due to how difficult it is to remove the vulnerability.

    The microcode revisions to fix the Spectre Varian 2 flaw in chips from the Bloomfield Xeon, Clarksfield, Gulftown, and Yorkfield families of chips to name a few, are marked as stopped due to several reasons.

  • Matthew Garrett Elaborates More On Lockdown + Secure Boot Pairing

    A few days back we covered the heated exchange on the kernel mailing list over the path being pursued by the Linux kernel "lockdown" patches. Those back and forth messages between Google's Matthew Garrett and Linus Torvalds have now spilled over into a blog post by Garrett.

    Linus Torvalds isn't against the kernel lockdown patches, he just is against it being explicitly enabled with UEFI SecureBoot and can't be easily turned off in that scenario. Matthew Garrett has written a blog post to lay out the case for UEFI SecureBoot with the lockdown functionality.

  • Public Hearing on IoT Risks

  • Hacking your brain(scan): [Windows] security bugs in EEG software open hospitals to attack

    Today, Cisco's Talos security research group revealed five security vulnerabilities in NeuroWorks, a Windows-based software that is used in multiple electroencephalogram systems sold by Nautus. The Windows-based Natus Xltek NeuroWorks 8 software uses hospitals' Ethernet networks to connect to EEG devices and integrate with patient data systems, and it is vulnerable to attacks that could allow remote code execution—allowing an attacker to gain access to the data on the device and to other systems on the hospital network—and denial of service. The systems hosting the software could then be used to stage wider attacks on hospital networks.

  • Cyberattack Bleeds Into Utility Space With Billing Delays

    At least five U.S. pipeline companies have said their electronic communications systems were shut down over the past few days, with four confirming the service disruptions were caused by a cyberattack. Energy Transfer Partners LP, Boardwalk Pipeline Partners LP, Chesapeake Utilities Corp.’s Eastern Shore Natural Gas and the TransCanada Corp.-operated Portland Natural Gas Transmission System were among the companies affected by data outages, while Oneok Inc. said it disabled its system as a precaution.

Reddit: News Corp Australia and Red Hat Enterprise Linux

Thursday 5th of April 2018 11:52:35 AM

As part of my job I find myself visiting a lot of offices and I always look to see what they use for a desktop. 80% of the time its Windows, 19% of the time its macOS and now I've seen my first Linux shop.

The troubling thing is that I was visiting News Corporation in Brisbane where a group of desktops were running what looked like GNOME but other than that I couldn't tell what they were using but I think i was RHEL because Ubuntu doesn't ship stock GNOME, SUSE barely has a presence in Australia and RHEL has like 5 or 6 offices here, including one in Brisbane, and basically powers this entire state's servers (and the Navy's). Anyway...

In case you don't know, News Corporation is basically the propaganda wing of the Turnbull regime, which is one of the most regressive and conservative governments in Australia's history that has chipped away at privacy controls and open source free software ideals. How can we put pressure on RH to stop dealing with News Corp?

LXer: Containerization, Atomic Distributions, and the Future of Linux

Thursday 5th of April 2018 11:46:36 AM
Linux has come a long way since Linus Torvalds announced it in 1991. It has become the dominant operating system in the enterprise space. And, although we’ve seen improvements and tweaks in the desktop environment space, the model of a typical Linux distribution has largely remained the same over the past 25+ years. The traditional package management based model has dominated both the desktop and server space.

  • Linux Needs Deep Pockets

    I love the operating systems revolving around the Linux Kernel. I think it’s amazing that something so good comes to the world so cheap or mostly free. You can do tremendous work on this platform, so it begs the question: Why aren’t more people using it? Here are the known benefits:

  • Open Standards, Open Source Come Together With New Tech-World Partnership

    The open-source-focused Linux Foundation is teaming with TM Forum, a communications technology industry group that has upped its open standards game in recent years.

    With a new partnership, the world of telecom is jumping into the world of open source with both feet.

    Last month, TM Forum, an association that represents communications service providers (CSPs) as they interact in the digital supply chain, announced it would team with the Linux Foundation, the nonprofit best known for shepherding its namesake, the open-source operating system on which the modern internet is largely built.

    The foundation is also known as a key steward of major open-source projects, and with the partnership, TM Forum will boost its open-source game, a change advocated by the CSPs it represents.

  • RADV Vulkan Driver Lands Out-of-Order Rasterization Support, Small Performance Boost

    The Mesa-based RADV Vulkan driver has landed initial support for out-of-rasterization support, but it's currently disabled by default.

    Back in 2016 AMD developers introduced the VK_AMD_rasterization_order extension for out-of-order rasterization handling. This VK_AMD_rasterization_order extension has been present since Vulkan 1.0.12 and has already been supported in AMDGPU-PRO.

  • dwm: A Minimalist Tiling Window Manager For Linux

    Tiling window managers have several advantages over their more popular cousins such as Gnome, KDE, XFCE, or Fluxbox. The feature of this post, dwm, takes these advantages to their most extreme.

    While most tiling managers strive to be lightweight, dwm keeps itself on a starvation diet of 2000 lines of code or fewer. All its configuration is done when it’s compiled, so it doesn’t read a runtime configuration file. It uses tags (the numbers 1 through 9), rather than arbitrarily-named window spaces, to group programs together. It can also be run entirely with keyboard commands, though it does incorporate mouse support for selecting and dragging windows when appropriate.

  • Clear Linux Shedding More Light On Their "Magic" Performance Work

    If you have been a Phoronix reader for any decent amount of time, you have likely seen how well Intel's Clear Linux distribution continues to run in our performance comparisons against other distributions. The developers behind this Linux distribution have begun a new blog series on "behind the magic" for some of the areas they are making use of for maximizing the out-of-the-box Linux performance.

    Their first post in their "behind the magic" series is on transparent use of library packages optimized for Intel's architecture... While they are optimizing for their own hardware as one would expect, let's not forget, Clear Linux does run on AMD hardware too; they are not doing any voodoo magic, which is why it pains me that more Linux distributions have not taken such a stance for better out-of-the-box speed. In fact, it runs on AMD hardware darn well as we have shown with our Ryzen and EPYC benchmarks. Obviously Intel tweaks their software packages for their own x86_64 CPUs, but even when testing on the AMD hardware Clear Linux tends to perform the best in terms of out-of-the-box performance and that Intel isn't doing anything to sabotage the performance otherwise.

    Full disclosure; this is an edited version of a live broadcast. You've heard me say it, and warn you about it. On this occasion, I decided it would be fun to take you through a tour of Linux based music player applications. To get said music on my system, I was also going to show you how to rip music from CDs using various applications. That's when things fell apart and my desktop lost track of the CD hardware. I do recover however and the whole thing does make for an interesting exercise in trying to figure out just what the heck went wrong so I can fix it before I submit to the growing panic. Because things went horribly wrong, at least for a while, I had to reboot my system which meant the show was suddenly in multiple parts. In assembling said parts into a semi-coherent whole, I may have added things here and there.

Graphics: VC4 and AMDVLK Driver

  • VC4 display, VC5 kernel submitted
    For VC5, I renamed the kernel driver to “v3d” and submitted it to the kernel. Daniel Vetter came back right away with a bunch of useful feedback, and next week I’m resolving that feedback and continuing to work on the GMP support. On the vc4 front, I did the investigation of the HDL to determine that the OLED matrix applies before the gamma tables, so we can expose it in the DRM for Android’s color correction. Stefan was also interested in reworking his fencing patches to use syncobjs, so hopefully we can merge those and get DRM HWC support in mainline soon. I also pushed Gustavo’s patch for using the new core DRM infrastructure for async cursor updates. This doesn’t simplify our code much yet, but Boris has a series he’s working on that gets rid of a lot of custom vc4 display code by switching more code over to the new async support.
  • V3D DRM Driver Revised As It Works To Get Into The Mainline Kernel
    Eric Anholt of Broadcom has sent out his revised patches for the "V3D" DRM driver, which up until last week was known as the VC5 DRM driver. As explained last week, the VC5 driver components are being renamed to V3D since it ends up supporting more than just VC5 with Broadcom VC6 hardware already being supported too. Eric is making preparations to get this VideoCore driver into the mainline Linux kernel and he will then also rename the VC5 Gallium3D driver to V3D Gallium3D.
  • AMDVLK Driver Gets Fixed For Rise of the Tomb Raider Using Application Profiles
    With last week's release of Rise of the Tomb Raider on Linux ported by Feral Interactive, when it came to Radeon GPU support for this Vulkan-only Linux game port the Mesa RADV driver was supported while the official AMDVLK driver would lead to GPU hangs. That's now been fixed. With the latest AMDVLK/XGL source code as of today, the GPU hang issue for Rise of the Tomb Raider should now be resolved.

AMD Ryzen 7 2700X Linux Performance Boosted By Updated BIOS/AGESA

With last week's initial launch-day Linux benchmarks of the Ryzen 5 2600X / Ryzen 7 2700X some found the Linux performance to be lower than Windows. While the root cause is undetermined, a BIOS/AGESA update does appear to help the Linux performance significantly at least with the motherboard where I've been doing most of my tests with the Ryzen 7 2700X. Here are the latest benchmark numbers. Read more

GNU: The GNU C Library 2.28 and Guix on Android

  • Glibc 2.28 Upstream Will Build/Run Cleanly On GNU Hurd
    While Linux distributions are still migrating to Glibc 2.27, in the two months since the release changes have continued building up for what will eventually become the GNU C Library 2.28. The Glibc 2.28 work queued thus far isn't nearly as exciting as all the performance optimizations and more introduced with Glibc 2.27, but it's a start. Most notable at this point for Glibc 2.28 is that it will now build and run cleanly on GNU/Hurd without requiring any out-of-tree patches. There has been a ton of Hurd-related commits to Glibc over the past month.
  • Guix on Android!
    Last year I thought to myself: since my phone is just a computer running an operating system called Android (or Replicant!), and that Android is based on a Linux kernel, it's just another foreign distribution I could install GNU Guix on, right? It turned out it was absolutely the case. Today I was reminded on IRC of my attempt last year at installing GNU Guix on my phone. Hence this blog post. I'll try to give you all the knowledge and commands required to install it on your own Android device.
  • GNU Guix Wrangled To Run On Android
    The GNU Guix transactional package manager can be made to run on Android smartphones/tablets, but not without lots of hoops to jump through first.
