  • Verizon joins O-RAN Alliance board

    After announcing earlier this year that the xRAN Forum and C-RAN Alliance were merging, the O-RAN Alliance announced new board members—including Verizon—and a collaboration with the Linux Foundation on open source software.

    Verizon’s participation in the O-RAN Alliance isn’t a surprise given its work on Open RAN initiatives and its earlier involvement in the xRAN Forum—it was a contributor to the xRAN fronthaul specification that was released in April. That specification defines open interfaces between the remote radio unit/head (RRU/RRH) and the baseband unit (BBU) to simplify interoperability between suppliers.

    [...]

    O-RAN also said it has started collaboration arrangements with The Linux Foundation to establish an open source software community for the creation of open source RAN software. Collaboration with The Linux Foundation will enable the creation of open source software supporting the O-RAN architecture and interfaces.

  • O-RAN Alliance and Linux to create an open source software community

    The O-RAN Alliance announced that Reliance Jio, TIM, and Verizon have joined the O-RAN board.

    AT&T CTO Andre Fuetsch says, “It’s encouraging to see the O-RAN Alliance off to such a strong start and gaining momentum as we welcome three new board members.

    “It’s important that the wireless industry continues to come together to drive forward O-RAN’s goals for open networking, software, and virtualisation in global wireless networks especially as 5G is closer than ever.”

  • Hyperledger Onboards 12 New Members Including Alibaba Cloud, Deutsche Telekom and Citi

    Hyperledger has onboarded 12 new members, including such major firms as Alibaba Cloud, Citi, and Deutsche Telekom, according to an announcement published on Dec. 11.
    Launched in 2016, Hyperledger is an open source project created by the Linux Foundation and created to support the development of blockchain-based distributed ledgers.
    The new members were announced at the Hyperledger Global Forum in Basel, Switzerland. The latest general members that joined the initiative include Alibaba Cloud, a subsidiary of the e-commerce giant; financial services firm Citigroup, Deutsche Telekom, one of the largest telecoms providers in Europe; and European blockchain trading platform we.trade, among others.

  • Open Source Compliance in the Enterprise

    Open Source Compliance in the Enterprise, 2nd edition, by Ibrahim Haddad outlines best practices for organizations to adopt and use open source code in products and services, as well as participate in open source communities in a legal and responsible way.

  • Linux Foundation Brings the Year to a Close with 21 New Members Making the Commitment to Open Source

    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced the addition of 18 Silver members and 3 Associate members. Linux Foundation members help support development of shared technology resources, while accelerating their own innovation through open source leadership and participation in some of the world’s most successful open source projects including Hyperledger, Kubernetes, Linux, Node.js and ONAP. Linux Foundation member contributions help provide the infrastructure and resources that enable the world’s largest open collaboration communities.

    Since the start of 2018, on average a new organization has joined The Linux Foundation every day.

The Hackaday Superconference is over, which is a shame, but one of the great things about our conference is the people who manage to trek out to Pasadena every year to show us all the cool stuff they’re working on. One of those people was [Piotr Esden-Tempski], founder of 1 Bit Squared, and he brought some goodies that would soon be launched on a few crowdfunding platforms. The coolest of these was the iCEBreaker, an FPGA development kit that makes it easy to learn FPGAs with an Open Source toolchain.

Poor IT governance prevented the IRS from making progress on a long-term effort to migrate 141 legacy applications from proprietary vendor software to open source Linux operating systems, according to an audit by the Treasury Inspector General for Tax Administration.

Under a migration plan developed in 2014, two-thirds of targeted applications and databases were supposed to have been successfully migrated by December 2016.

However, only eight of the 141 applications targeted have successfully transitioned to Linux as of February 2018. More than one third have not even started.

  • Wayland's Weston Switching Over To The Meson Build System

    Complementing the Meson build system support for Wayland itself, the Weston reference compositor now has been Meson-ized.

    Pekka Paalanen and Daniel Stone, both of Collabora, have landed the Meson build system support for the Weston compositor. At this stage the new build system should be fully working and correct.

  • AMDGPU DC Gets Polaris Corruption Fix, Some Code Refactoring

    AMD has published their latest batch of "DC" Display Core patches for the AMDGPU Linux kernel driver.

    This batch of 45 patches against this display code for the AMDGPU Direct Rendering Manager driver has some code cleanups and refactoring, changes some error messages to just warnings, and has a display corruption fix affecting some Polaris hardware.

  • Investigating GitLab

    The Direct Rendering Manager (DRM) kernel subsystem is a fairly small part of the kernel, he said. It is also a fairly small part of the open-source graphics stack, which is under the X.Org umbrella. DRM sits in the middle between the two, so the project has learned development tools and workflows from both of the larger projects.

    The kernel brought DRM into the Git world in 2006, which was just a year after Git came about; it was a "rough ride" back then, Vetter said. With Git came "proper commit messages". Prior to that, the X.org commit messages might just be a single, unhelpful line; now those messages explain why the change is being made and what it does. The idea of iterating on a patch series on the mailing list came from the kernel side as did the "benevolent dictator" model of maintainership. DRM, the X server, Wayland, and others all followed that model along the way.

    From the X.Org side came things like the committer model; in Mesa, every contributor had commit rights. That model has swept through the graphics community, so now DRM, the X server, and Wayland are all run using that scheme. Testing and continuous integration (CI) is something that DRM has adopted from X.Org; the kernel also does this, but DRM has adopted the X.Org approach, tooling, and test suites. For historical reasons, "almost everything" is under the MIT license, which comes from X.Org projects as well.

    There has been a lot of movement of tools and development strategies in both directions via the DRM subsystem. He thinks that using GitLab may be "the next big wave of changes" coming from the user-space side to kernel graphics, and maybe to the kernel itself eventually. This won't happen this year or next year, Vetter predicted, but over the next few years we will see GitLab being used more extensively.

  • AMDGPU For Linux 4.20 Gets The Final Radeon RX 590 Fix, Adds The New Vega PCI IDs

    With just over one week to go until the expected Linux 4.20 kernel release, Alex Deucher of AMD today sent in the latest batch of fixes to the DRM tree for landing at the end of this cycle.

    Notable about this latest set of "fixes" for the AMDGPU kernel graphics driver are:

    - The final Radeon RX 590 fix so this newer Polaris GPU no longer hangs under load. So once this Linux 4.20 material is merged to mainline, this month-old Polaris graphics card should now be happily running on Linux -- assuming you also have the latest Polaris firmware files and a recent version of Mesa. See our Radeon RX 590 benchmarks article for more details.

  • AMDVLK 2018.Q4.4 Driver Update Brings Performance Improvements, New Vulkan Bits

    AMD developers today outed their latest "AMDVLK" open-source Vulkan driver code drop dubbed AMDVLK 2018.Q4.4.

  • NVIDIA 415.23 Driver Fixes Build Issues Against Linux 4.20 Kernel

    The NVIDIA 415.23 driver was issued just to fix a build issue against the near-final Linux 4.20 kernels. In particular, there has been a build failure around the vm_insert_pfn function that is now worked around when building the NVIDIA proprietary driver's shim against the Linux 4.20 release candidates.

  • 2018-2019 Elections Underway with Calls for Candidates and New Members

    Earlier this week, on Tuesday, Dec. 11, 2018, the Elections Committee posted the Schedule for the 2018-2019 openSUSE Board Elections, along with the announcement of a Membership Drive and a call for nominations and applications for Candidates to fill three vacant seats on the openSUSE Board.

    The annual Board Elections are normally expected to run in November and December, with ballots cast and results published in time for the newly-elected Board Members to take their seats on the Board at the beginning of January. However, some additional work needed to be completed for this election, and the elections were delayed in part to accommodate the additional work.

  • SUSE Linux Enterprise 12 Service Pack 4 is Generally Available

    SUSE Linux Enterprise 12 Service Pack 4 is now generally available. Service Pack 4 marks the fourth generation of SUSE Linux Enterprise Server 12, a major code stream and product foundation with a lifecycle from 2014 to 2024 plus Long Term Support (10+3 years).
    This release consolidates all fixes and updates introduced since SUSE Linux Enterprise 12 Service Pack 3.

  • Making the Selection

    You’ve likely read or heard a lot about today’s data explosion and how it’s affecting enterprises. After combing through all the overexcited rhetoric about how quickly data is multiplying or how

    many petabytes you’ll soon have to handle, one thing remains clear: You need to find a new way to store and manage your data or you’ll get left behind.

    While that mandate puts pressure on your organization to act quickly, it’s also the catalyst to a whole new world of exciting opportunities. More data can mean deeper, more accurate insights into your operations and customer needs, which empowers you to streamline processes and personalize experiences like never before. More data can also lead to greater innovation and new sources of revenue.

Programming/Development: mental illness, newt, and more

  • One developer's road: Programming and mental illness

    The next year, I went to college and learned about SUSE Linux 6.1 and the Java SE 1.2 programming language. Another student introduced me to free software and the GNU GPL License and helped me install SuSE 7.1 on my new Compaq Evo N160c notebook.

    There was no more Microsoft software on my computer. The GNU/Linux operating system was exactly what I wanted, offering editors, compilers, and a command line that did auto-completion.

    Six months later, I installed Debian GNU/Linux. Since YaST2 was just a front end to configuration files, I had to use Debian Potato. My bootloader of choice was LILO, and the Second Extended File System was reliable—not buggy, like ReiserFS.

    In spring 2002, I read a book about the C programming language. I wanted to learn to do UIs like javax.swing, and a friend recommended Gtk+ 2.0, which was about to be released. At this point, I stopped using the KDE Desktop Environment. Gnome 2 was different and provided anti-aliased fonts with hinting. I used it to play Chromium B.S.U., and KNOPPIX did the magic.

  • newt

    I've been helping teach robotics programming to students in grades 5 and 6 for a number of years. The class uses Lego models for the mechanical bits, and a variety of development environments, including Robolab and Lego Logo on both Apple ][ and older Macintosh systems. Those environments are quite good, but when the Apple ][ equipment died, I decided to try exposing the students to an Arduino environment so that they could get another view of programming languages.

    The Arduino environment has produced mixed results. The general nature of a full C++ compiler and the standard Arduino libraries means that building even simple robots requires a considerable typing, including a lot of punctuation and upper case letters. Further, the edit/compile/test process is quite long making fixing errors slow. On the positive side, many of the students have gone on to use Arduinos in science research projects for middle and upper school (grades 7-12).

    In other environments, I've seen Python used as an effective teaching language; the direct interactive nature invites exploration and provides rapid feedback for the students. It seems like a pretty good language to consider for early education -- "real" enough to be useful in other projects, but simpler than C++/Arduino has been. However, I haven't found a version of Python that seems suitable for the smaller microcontrollers I'm comfortable building hardware with.

  • The Linux Link Tech Show Episode 787
  • FLOSS Weekly 510: YottaDB

    A lifelong hacker and geek, K.S. Bhaskar has been programming for almost half a century, and as a consequence of the technology gap between India and the US when he was an undergraduate, has programmed computers designed in the 1950s. He spent many years in the electronic test and measurement, and scientific computing worlds before moving to databases and the predecessor of YottaDB. He led GT.M, the predecessor of YottaDB from 1995 to 2017, before founding YottaDB in 2017 to take that code base – which by then felt to him like one of his children – to new markets and applications.

    Christopher is a true geek, and from a young start always wondered how the world works. He knew from a young age the computer field is where he was going to wind up working due to the infinite ways they could be used and cool things they could be made to do. Christopher has spent time in the healthcare industry working with YottaDB/GT.M/M and applying modern software development techniques to it. He also is a maker with more Raspberry Pis, Arduinos, other development boards, along with a 3d printer to keep himself busy.

LWN Articles About Linux (Kernel)

  • Bounded loops in BPF programs

    The BPF verifier is charged with ensuring that any given BPF program is safe for the kernel to load and run. Programs that fail to terminate are clearly unsafe, as they present an opportunity for denial-of-service attacks. In current kernels, the verifier uses a heavy-handed technique to block such programs: it disallows any program containing loops. This works, but at the cost of disallowing a wide range of useful programs; if the verifier could determine whether any given loop would terminate within a bounded time, this restriction could be lifted. John Fastabend presented a plan for doing so during the BPF microconference at the 2018 Linux Plumbers Conference.

    Fastabend started by noting that the lack of loops hurts; BPF developers are doing "crazy things" to work around their absence. He is working to enable the use of simple loops that can be modeled by the verifier. There is academic work on ways to verify more complex loops, but that is a problem for later. For now, the objective is to detect simple loops and verify that they will terminate; naturally, it's important that the verifier, too, is able to terminate in a reasonable amount of time.

  • Binary portability for BPF programs

    The BPF virtual machine is the same on all architectures where it is supported; architecture-specific code takes care of translating BPF to something the local processor can understand. So one might be tempted to think that BPF programs would be portable across architectures but, in many cases, that turns out not to be true. During the BPF microconference at the Linux Plumbers Conference, Alexei Starovoitov (assisted by Yonghong Song, who has done much of the work described) explained the problem and the work that has been done toward "compile once, run everywhere" BPF.

    Many BPF programs are indeed portable, in that they will load and execute properly on any type of processor. Packet-filtering programs, in particular, usually just work. But there is a significant class of exceptions in the form of tracing programs, which are one of the biggest growth areas for BPF. Most tracing tools have two components: a user-space program invoked by the user, and a BPF program that is loaded into the kernel to filter, acquire, and possibly boil down the needed data. Both programs are normally written in C.

  • Taming STIBP

    The Spectre class of hardware vulnerabilities was apparently so-named because it can be expected to haunt us for some time. One aspect of that haunting can be seen in the fact that, nearly one year after Spectre was disclosed, the kernel is still unable to prevent one user-space process from attacking another in some situations. An attempt to provide that protection using a new x86 microcode feature called STIBP has run into trouble once its performance impact was understood; now a more nuanced approach may succeed in providing protection where it is needed without slowing down everybody else.

    The Spectre variant 2 vulnerability works by polluting the CPU's branch-prediction buffer (BPB), which is used during speculative execution to make a guess about which branch(es) the code will take; see this article for a refresher on the Spectre vulnerabilities if needed. Closing this hole requires changes at a number of levels, but a fundamental part of the problem is preventing any code that may be targeted from running with a BPB that has been trained by an attacker.

  • The x32 subarchitecture may be removed

    The x32 subarchitecture is a software variant of x86-64; it runs the processor in the 64-bit mode, but uses 32-bit pointers and arithmetic. The idea is to get the advantages of x86-64 without the extra memory usage that goes along with it. It seems, though, that x32 is not much appreciated; few distributions support it and the number of users appears to be small.

Linux on the Desktop: Are We Nearly There Yet?

Filed under
GNU
Linux

The numbers are pretty stark: Linux might be the backbone of everything from embedded devices to mainframes and super computers. But it has just a 2% share of desktops and laptops.

It seems the only way to get most people to even touch it is to rip away everything you recognise as Linux to rebuild it as Android.

Until recently, I was in the 98%. I honestly wasn’t even conflicted. I used Linux most days both for work and for hobbies – but always in the cloud or on one of those handy little project boards that are everywhere now. For my daily driver, it was Windows all the way.

I guess what’s kept me with Windows so long is really that it’s just been good enough as a default option that I haven’t been prompted to even think about it. Which, to be fair, is a great quality in an operating system.

The last time I tried a dual boot Linux/Windows setup was about 15 years ago. I was using Unix at university, and was quite attracted to the idea of free and open source software, so I decided to give it a go.

This was back when, if you wanted to install Linux, you went to the newsagent and bought a magazine that had a CD-ROM on the front cover. I don’t exactly remember what distro it was – probably something like Slackware or Red Hat.

Legal

I am the current licensing and compliance manager for the FSF, though I've had several roles in my time here. The Lab handles all the free software licensing work for the FSF. Copyleft is the best legal tool we have for protecting the rights of users, and the Lab makes sure that tool is at full power by providing fundamental licensing education. From publishing articles and resources on free software licensing, to doing license compliance work for the GNU Project, to handling our certification programs like Respects Your Freedom, if there is a license involved, the Lab is on the case.

When I started working at the FSF part-time in 2008, the GNU General Public License version 3 (GPLv3) was only a year old. Our Respects Your Freedom certification program didn't yet exist. The Free Software Directory wasn't yet a wiki that could be updated by the community at large. Things have changed a lot over the years, as has our ability to help users to understand and share freely licensed works. I'd like to take just a moment as 2018 draws to a close to look back on some of the great work we accomplished.
