  • February 2018 coreboot update now available

    Hey everyone, I’m happy to announce the release of an update to our coreboot images for Librem 13 v2 and Librem 15 v3 machines.

    All new laptops will come pre-loaded with this new update, and everyone else can update their machines using our existing build script which was updated to build the newest image. Some important remarks:

  • Purism Releases Updated Coreboot Images For Their Laptops

    Purism has released updated Coreboot images for their Librem 13 v2 and Librem 15 v3 laptops.

    The updated Coreboot images are now re-based to Coreboot 4.7, Intel FSP 2.0, IOMMU (VT-d) support is now available, TPM support is also enabled, and there are fixed ATA errors for 6Gbps speeds.

  • New Inventory with TPM by Default, Free International Shipping

    In November, we announced the availability of our Trusted Platform Module as a $99 add-on for early adopters, something that would allow us to cover the additional parts & labor costs, as well as test the waters to see how much demand there might be for this feature. We thought there would be “some” interest in that as an option, but we were not sure how much, especially since it was clearly presented as an “early preview” and offered at extra cost.

Canonical Releases Major Kernel Security Update for Ubuntu 14.04 to Fix 26 Flaws

Filed under
Linux

A total of 26 security flaws were fixed in today's kernel update for Ubuntu 14.04 LTS systems and derivatives, including an out-of-bounds write vulnerability in Linux kernel's F2F (Flash-Friendly File System) file system, a use-after-free flaw in Linux kernel's ALSA PCM subsystem, and an integer overflow in Linux kernel's sysfs interface for the QLogic 24xx+ series SCSI driver.

Additionally, the kernel update addresses a use-after-free vulnerability in Linux kernel's SCTP protocol implementation, as well as a race condition in the LEGO USB Infrared Tower driver and a use-after-free vulnerability in the USB serial console driver, both allowing a physically proximate attacker to execute arbitrary code or crash the system with a denial of service attack.

Plasma Mobile Could Give Life to a Mobile Linux Experience

KDE
Linux

In the past few years, it’s become clear that, outside of powering Android, Linux on mobile devices has been a resounding failure. Canonical came close, even releasing devices running Ubuntu Touch. Unfortunately, the idea of Scopes was doomed before it touched down on its first piece of hardware and subsequently died a silent death.

The next best hope for mobile Linux comes in the form of the Samsung DeX program. With DeX, users will be able to install an app (Linux On Galaxy—not available yet) on their Samsung devices, which would in turn allow them to run a full-blown Linux distribution. The caveat here is that you’ll be running both Android and Linux at the same time—which is not exactly an efficient use of resources. On top of that, most Linux distributions aren’t designed to run on such small form factors. The good news for DeX is that, when you run Linux on Galaxy and dock your Samsung device to DeX, that Linux OS will be running on your connected monitor—so form factor issues need not apply.

Overview Of tcpdump With Examples

Filed under
Linux

You can view information about traffic coming and going from a given network interface using tcpdump. This diagnostic tool allows you to see packet information, that is where incoming packets come from and where outgoing packets are heading to on an interface, with some extra information. You can even save the output to a file to inspect later on. This article will demonstrate the simple examples of tcpdump.

Kernel: CH341 and LWN Articles (Just Freed)

  • Linux Adds CH341 GPIO

    There was a time when USB to serial hardware meant one company: FTDI. But today there are quite a few to choose from and one of the most common ones is the WCH CH341. There’s been support for these chips in Linux for a while, but only for use as a communication port. The device actually has RS232, I2C, SPI, and 8 general purpose I/O (GPIO) pins. [ZooBaB] took an out-of-tree driver that exposes the GPIO, and got it working with some frightening-looking CH341 boards.

  • Shrinking the kernel with an axe

    This is the third article of a series discussing various methods of reducing the size of the Linux kernel to make it suitable for small environments. The first article provided a short rationale for this topic, and covered link-time garbage collection. The second article covered link-time optimization (LTO) and compared its results to link-time garbage collection. In this article we'll explore ways to make LTO more effective at optimizing kernel code away, as well as more assertive strategies to achieve our goal.

  • The rest of the 4.16 merge window

    At the close of the 4.16 merge window, 11,746 non-merge changesets had been merged; that is 5,000 since last week's summary. This merge window is thus a busy one, though not out of line with its predecessors — 4.14 had 11,500 changesets during its merge window, while 4.15 had 12,599. Quite a bit of that work is of the boring internal variety; over 600 of those changesets were device-tree updates, for example. But there was still a fair amount of interesting work merged in the second half of the 4.16 merge window; read on for the highlights.

  • Linux Kernel Module Growth

    The Linux kernel grows at an amazing pace, each kernel release adds more functionality, more drivers and hence more kernel modules. I recently wondered what the trend was for kernel module growth per release, so I performed module builds on kernels v2.6.24 through to v4.16-rc2 for x86-64 to get a better idea of growth rates...

  • A Linux Kernel Driver Is Being Worked On For Valve's Steam Controller

    Right now to make most use of the Steam Controller on Linux you need to be using the Steam client while there have been independent user-space programs like SC-Controller to enable Steam Controller functionality without the Steam client running. A new and independent effort is a Linux kernel driver for the Steam Controller.

    Through reverse-engineering, Rodrigo Rivas Costa has been developing a kernel driver for the Valve Steam Controller. This driver supports both USB cable and USB wireless adapters for the Steam Controller. This driver is being developed as a proper HID kernel driver so it should work with all existing Linux programs and doesn't require the use of the proprietary Steam client.

GNOME and Fedora

  • RFC: Integrating rsvg-rs into librsvg
    I have started an RFC to integrate rsvg-rs into librsvg. rsvg-rs is the Rust binding to librsvg. Like the gtk-rs bindings, it gets generated from a pre-built GIR file.
  • 1+ year of Fedora and GNOME hardware enablement
    A year and a couple of months ago, Christian Schaller asked me to pivot a little bit from working full time on Fleet Commander to manage a new team we were building to work on client hardware enablement for Fedora and GNOME with an emphasis on upstream. The idea was to fill the gap in the organization where nobody really owned the problem of bringing up new client hardware features vertically across the stack (from shell down to the kernel), or rather, ensure Fedora and GNOME both work great on modern laptops. Part of that deal was to take over the bootloader and start working closer to customers and hardware manufacturing parnters.
  • Fedora Atomic Workstation: Works on the beach
    My trip is getting really close, so I decided to upgrade my system to rawhide. Wait, what ? That is usually what everybody would tell you not to do. Rawhide has this reputation for frequent breakage, and who knows if my apps will work any given day. Not something you want to deal with while traveling.

Why You Shouldn’t Use Firefox Forks (and Proprietary Opera)

  • Why You Shouldn’t Use Firefox Forks Like Waterfox, Pale Moon, or Basilisk
    Mozilla Firefox is an open source project, so anyone can take its code, modify it, and release a new browser. That’s what Waterfox, Pale Moon, and Basilisk are—alternative browsers based on the Firefox code. But we recommend against using any of them.
  • Opera Says Its Next Opera Release Will Have the Fastest Ad Blocker on the Block
    Opera Software promoted today its upcoming Opera 52 web browser to the beta channel claiming that it has the faster ad blocker on the market compared to previous Opera release and Google Chrome. One of the key highlights of the Opera 52 release will be the improved performance of the built-in ad blocker as Opera claims to have enhanced the string matching algorithm of the ad blocker to make it open web pages that contain ads much faster than before, and, apparently than other web browsers, such as Chrome.

Graphics: Glxinfo, ANV, SPIR-V

  • Glxinfo Gets Updated With OpenGL 4.6 Support, More vRAM Reporting
    The glxinfo utility is handy for Linux users in checking on their OpenGL driver in use by their system and related information. But it's not often that glxinfo itself gets updated, except that changed today with the release of mesa-demos-8.4.0 as the package providing this information utility. Mesa-demos is the collection of glxinfo, eglinfo, glxgears, and utilities related to Mesa. With the Mesa-demos 8.4.0 it is predominantly glxinfo updates.
  • Intel ANV Getting VK_KHR_16bit_storage Support Wrapped Up
    Igalia's Jose Maria Casanova Crespo sent out a set of patches today for fixes that allow for the enabling of the VK_KHR_16bit_storage extension within Intel's ANV Vulkan driver. The patches are here for those interested in 16-bit storage support in Vulkan. This flips on the features for storageBuffer16BitAccess, uniformAndStorageBuffer16BitAccess, storagePushConstant16 and the VK_KHR_16bit_storage extension. This support is present for Intel "Gen 8" Broadwell graphics and newer. Hopefully the work will be landing in Mesa Git soon.
  • SPIR-V Support For Gallium3D's Clover Is Closer To Reality
    It's been a busy past week for open-source GPU compute with Intel opening up their new NEO OpenCL stack, Karol Herbst at Red Hat posting the latest on Nouveau NIR support for SPIR-V compute, and now longtime Nouveau contributor Pierre Moreau has presented his latest for SPIR-V Clover support. Pierre has been spending about the past year adding SPIR-V support to Gallium3D's "Clover" OpenCL state tracker. SPIR-V, of course, is the intermediate representation used now by OpenCL and Vulkan.

Security: Updates, Tinder, FUD and KPTI Meltdown Mitigation

  • Security updates for Friday
  • Tinder vulnerability let hackers [sic] take over accounts with just a phone number

    The attack worked by exploiting two separate vulnerabilities: one in Tinder and another in Facebook’s Account Kit system, which Tinder uses to manage logins. The Account Kit vulnerability exposed users’ access tokens (also called an “aks” token), making them accessible through a simple API request with an associated phone number.

  • Another Potential Performance Optimization For KPTI Meltdown Mitigation
    Now that the dust is beginning to settle around the Meltdown and Spectre mitigation techniques on the major operating systems, in the weeks and months ahead we are likely to see more performance optimizations come to help offset the performance penalties incurred by mitigations like kernel page table isolation (KPTI) and Retpolines. This week a new patch series was published that may help with KPTI performance.
