diff -u: Automated Bug Reporting

Filed under
Linux

A variety of automated bug-hunters are roaming around reporting bugs. One of them is Syzbot, an open-source tool specifically designed to find bugs in Linux and report them. Dmitry Vyukov recently sent in a hand-crafted email asking for help from the community to make Syzbot even more effective.

The main problems were how to track bugs after Syzbot had reported them and how to tell when a patch went into the kernel to address a given bug.

It turned out that Andrey Ryabinin and Linus Torvalds got together to collaborate on an easy solution for Dmitry's problem: Syzbot should include a unique identifier in its own email address. The idea is that anything after a "+" in an email address is completely ignored. So zbrown@gmail.com is exactly the same as zbrown+stoptrump@gmail.com. Andrey and Linus suggested that Syzbot use this technique to include a hash value associated with each bug report. Then, Linux developers would include that email address in the "Reported-By" portion of their patch submissions as part of the normal developer process.

Real-time Linux based automation controller supports up to 16 I/O modules

Filed under
Linux

Opto 22 announced its first Linux-based automation controller: a rugged “Groov EPIC” system that runs real-time Linux on a quad-core ARM SoC, and supports process and machine control, SCADA/RTU, and industrial IoT edge gateway applications.

Increasingly, industrial equipment manufacturers must not only compete on features, but also meet their clients’ need to attract the best developers. That often means shifting from proprietary RTOS or Windows based solutions to Linux. The latest to make the switch is Opto 22, whose announcement suggests the Groov EPIC controller represents a major new product direction compared to its previous Groov products.

Patent Troll MPEG LA Wants People to Stay With MPEG

Filed under
Movies
  • Waddawewant? Free video codecs! When do we... oh, look, the last MPEG-2 patent expired!

    It's almost of historical interest only, but everywhere except the Philippines and Malaysia, the last MPEG-2 video encoder/decoder patents have expired.

    As *nixcraft noted, what it means is that there will never again be the risk of an MPEG-2 decoder being bombed in the libre operating system world.

    The company that had the patents wrapped up for licensing, MPEG LA, told the world the last US patent expired on 13 February here .

  • Race on to bring AV1 open source codec to market, as code freezes

    The long-heralded open source AV1 codec is now set for development of commercial product, with the code complete and ready to be frozen over the next few weeks. This has been confirmed by contributors to the standard such as Austrian transcoding software developer Bitmovin, which hopes to be among the first to bring out a product. That will happen once members of the Alliance for Open Media (AOM) that developed the codec sign off its performance.

    Khronos' glTF transmission format for 3D scenes and models continues getting better. This 3D format has seen adoption by countless applications and engines and even usage within Microsoft products. Khronos' latest advancement to glTF 2.0 is a compression extension.

  • Intel Open-Sources LLVM Graphics Compiler, Compute Runtime With OpenCL 2.1+

    Now it's clear why Intel hasn't been working on the Beignet code-base in months as they have been quietly working on a new and better OpenCL stack and run-time! On open-source Intel OpenCL you can now have OpenCL 2.1 while OpenCL 2.2 support is on the way.

    Intel by way of their Open-Source Technology Center quietly open-sourced a new compute runtime as well as an LLVM-based graphics compiler. Thanks to a sharp-eyed Phoronix reader for spotting and pointing out to us this new Intel OpenCL stack that hasn't really received any attention at all yet.

  • DRI3 v1.1 Updated by Collabora For Modifiers & Multi-Plane Support

    As a sign that DRI3 v1.1 is hopefully ready to go, Louis-Francis Ratté-Boulianne of Collabora on Friday sent out his latest set of patches adding modifiers and multi-plane support to the Direct Rendering Infrastructure.

    DRI3 v1.1 has been a long, ongoing project for this first major addition to the DRI3 infrastructure. Namely there is support for explicit format modifiers and pixmaps backed by multi-planar buffers. Collabora has also already been working on some experimental DRI3 v1.2 patches for DMA fences, which originally was part of the v1.1 patches, but then pushed back to their own series.

  • Solus 4 To Offer Experimental GNOME Wayland Session, MATE UI Refresh

    The Solus Linux distribution has offered up some new details this week on their upcoming Solus 4 release.

    First up, their integration of Snap package management (snapd) has been deferred so it's no longer a release blocker. They will land the Snap support though still in the future when it's ready.

  • KDE Amarok Music Player Receives Revived Port To Qt5 / KF5

    While Amarok was once KDE's dominant music player, it hasn't seen a new release now in about five years and has yet to see a release based on Qt5 and KDE Frameworks 5. But there's hope that might still happen.

    In the absence of a modern Amarok release there have been plenty of other KDE media players coming about like Elisa and Babe, but coming out today is an updated patch for bringing Amarok to a Qt5/KF5 world.

How to make sense of the Apache 2 patent license

Filed under
Red Hat
OSS
Legal

In essence, when a software developer contributes code to a project (i.e., the Work under the license), he or she becomes a Contributor. Under the above term, Contributors are granting permission to use any of their patents that may read on their contribution. This provides peace of mind to users since the Contributor would likely be prevented from pursuing patent royalties from any users of the software covering that contribution to the project.

Complexities arise when the software developer contributes code that is not claimed by any of the Contributor's patents by itself, but only when combined with the Apache 2.0 licensed open source program to which the contribution was made (i.e., the Work under the license). Thus, the Contributor owning such a patent could pursue patent royalties against a user of that revised Work. The authors of the Apache 2.0 license were forward thinking and account for this scenario. Section 3 states that the license applies to "patent claims licensable by such Contributor that are necessarily infringed... by a combination of their Contribution(s) with the Work to which such Contributions was submitted."

  • Ubuntu Adds New “Minimal Installation” Option For Fewer Preinstalled Packages

    The development of the next Ubuntu LTS release, i.e., Ubuntu 18.04 Bionic Beaver, is going on in full swing. The desktop development team has decided to add a new option in the installation process that allows you to perform a lean installation of Ubuntu.

    The Unity 7.4.5 update isn’t big on new features but it is big on bug fixes and general all-round improvements.

  • Snapcraft through the eyes of it’s biggest community contributor

    If you’ve spent any time in the Snapcraft forum, it’s quite likely you’ve come across Dan Llewellyn – a keen community advocate or self-proclaimed Snapcrafter. Dan has always had a passion for computing and is completely self-taught. Outside of the community, Dan is a freelance WordPress developer. After getting into the open source world around 1998, he has switched between various Linux distros including Suse, RedHat, Gentoo before settling on Ubuntu from the 5.04 release onwards. A longtime participant in the UK Ubuntu chatroom – where he met Canonical’s Alan Pope – Dan admits he was never that active before Snapcraft came along.

    It was spending time in the UK chatroom around 2016 that he discovered snaps which piqued his interest. “I saw the movement of changing Clicks to snaps and thought it was an interesting idea. It’s more widely focused than a mobile app delivery system and I’ve always liked things that also worked on the server, IoT and elsewhere” Dan comments. With a previous desire to get into mobile app development and seeing the move away from Ubuntu Touch, Dan was eager to see Snapcraft succeed and felt like it was something he could contribute to.

OpenBSD Gets Mitigated For Meltdown CPU Vulnerability

  • OpenBSD Gets Mitigated For Meltdown CPU Vulnerability
    A few days back FreeBSD 11 stable was mitigated for Meltdown (and Spectre vulnerabilities), which came more than one month after these nasty CPU vulnerabilities were disclosed while DragonFlyBSD was quickly mitigated and the first of the BSDs to do so. While OpenBSD is known for its security features and focus, only today did it land its initial Meltdown mitigation.
  • Meltdown fix committed by guenther@

    Meltdown mitigation is coming to OpenBSD. Philip Guenther (guenther@) has just committed a diff that implements a new mitigation technique to OpenBSD: Separation of page tables for kernel and userland. This fixes the Meltdown problems that affect most CPUs from Intel. Both Philip and Mike Larkin (mlarkin@) spent a lot of time implementing this solution, talking to various people from other projects on best approaches.

    In the commit message, Philip briefly describes the implementation [...]

France Proposes Software Security Liability For Manufacturers, Open Source As Support Ends

It sometimes seems as though barely a week can go by without yet another major software-related hardware vulnerability story. As manufacturers grapple with the demands of no longer building simple appliances but instead supplying them containing software that may expose itself to the world over the Internet, we see devices shipped with insecure firmware and little care for its support or updating after the sale. The French government have a proposal to address this problem that may be of interest to our community, to make manufacturers liable for the security of a product while it is on the market, and with the possibility of requiring its software to be made open-source at end-of-life. In the first instance it can only be a good thing for device security to be put at the top of a manufacturer’s agenda, and in the second the ready availability of source code would present reverse engineers with a bonanza.
