Security

First up, in this release, the Docker Engine will now automatically verify the provenance and integrity of all Official Repos using digital signatures. Official Repos are Docker images curated and optimized by the Docker community to be the best building blocks for assembling distributed applications. A valid signature provides an added level of trust by indicating that the Official Repo image has not been tampered with.

The Advantages of Computer Hardware Designed For Linux

Filed under
Linux

When you buy a computer with Linux pre-installed, like when you buy from Apple, you can be sure that the hardware works beautifully with your chosen operating system. OK, so the hardware may not have been designed specifically to run Linux, but the computer vendor has chosen that hardware specifically because it DOES work well with Linux -- any Linux!

You can install Linux on almost any computer hardware -- Mac or Windows PC. There is a reason, when you buy a computer to run Linux, that you should get one with Linux pre-installed. It's because you can be sure you'll have the "just works" experience with whatever version of Linux you choose to install in the future.

Integrating Trac, Jenkins and Cobbler—Customizing Linux Operating Systems for Organizational Needs

Filed under
GNU
Linux

Organizations supporting Linux operating systems commonly have a need to build customized software to add or replace packages on production systems. This need comes from timing and policy differences between customers and the upstream distribution maintainers. In practice, bugs and security concerns reported by customers will be prioritized to appropriate levels for the distribution maintainers who are trying to support all their customers. This means that customers often need to support patches to fill the gap, especially for unique needs, until distribution maintainers resolve the bugs.

Sony Z1 and Z2 added to Xperia open-source project with unified kernels

Filed under
Android
Linux
Gadgets

The Xperia Z1 and Xperia Z2 are now a part of Sony's open source efforts, and unifies them with a common kernel based on the Qualcomm MSM8974 platform. This won't mean much for everyday users, since applying the software to either device means you won't be able to take pictures or make phone calls, but it will make life easier for folks who tinker with custom ROMs.

The kernel unification means developers will be able to cook something up for both devices at once, rather than needing separate ROMs for each. This is a great start, but there are plenty of Z variant models that could benefit from this AOSP treatment as well.

JIM ZEMLIN is excited. We've caught up with him backstage at LinuxCon in Dusseldorf where, as executive director of The Linux Foundation, he has just given a keynote. But it's not that which is exciting him right now. It's the fact that he's in the home of Kraftwerk.

"The other people with me in the room hadn't heard of this band, but did you know that Kraftwerk are from Dusseldorf? One of the original German electronica bands! I told you guys!" he beams.

On Tuesday, Munich's first mayor finally reacted to an inquiry by the Green Party (in German) related to rumours regarding a possible switch back to a Windows-based desktop environment. The answer to the inquiry shows that there is no factual basis for the claims made by first mayor and second mayor. An evaluation of the IT infrastructure and -processes is underway. FSFE calls on the city council to include vendor independence as well as interoperability as factors in the investigation, since they were central reasons for Munich to switch to Free Software in the first place.

What ARC does have is Linux support. In fact, Synopsys’s brand new ARC HS38 processor supports both “standard” single-core and SMP multicore implementations of Linux, something a bit new and unusual in the DIY processor arena. So just because you’ve rolled your own processor hardware doesn’t mean you have to give up on familiar operating systems.

Linux-Turned-FreeBSD Distro Comes Up With A New Software License

Filed under
Linux
BSD

While the likes of SprezzOS as the "most beautiful and performant" Linux and OSu as the ultimate operating system have disappeared at the end of the day and are no longer providing comic relief or interesting ambitious debates to Linux users, that other distribution based on Ubuntu and then turned into a FreeBSD distribution is still standing. They're out with an update today and have introduced their own open-source license.

The OS being talked about here for today's after-hours forum discussion fodder is Jabir OS, the operating system that now claims to be an independent fork of FreeBSD and most recently they've been trying to make their own operating system GUI.

    The above are just a sampling of this week's SDN and NFV news, attesting to the industry interest in the emerging technologies, interest that was further evidenced by yesterday's announcement from Dell'Oro Group that SDN datacenter sales will grow more than 65 percent this year. "With architectures ratified and production deployments under way, network security appliances and Ethernet switches will continue to comprise the majority of SDN's impact, with SDN gaining a foothold outside of the major cloud providers," the research firm said while hawking a for-sale report.

  • Setting the SDN Agenda

    So what are going to be the hot topics of debate this week? I've been here a day, sitting in on the Open Networking Foundation (ONF) workshop and chatting to a number of companies with a vested interest in SDN's future success, and there are a number of debates likely to rage all week:

  • State of Linux Containers
    In this video from the Stanford HPC Conference, Christian Kniep from Docker Inc. presents: State of Containers. “This talk will recap the history of and what constitutes Linux Containers, before laying out how the technology is employed by various engines and what problems these engines have to solve. Afterward, Christian will elaborate on why the advent of standards for images and runtimes moved the discussion from building and distributing containers to orchestrating containerized applications at scale. In conclusion, attendees will get an update on what problems still hinder the adoption of containers for distributed high performance workloads and how Docker is addressing these issues.”
  • ONS 2018: Networking Reimagined
    For the past seven years, Open Networking Summit (ONS) has brought together the networking industry’s ecosystem of network operators, vendors, open source projects, leading researchers, and investors to discuss the latest SDN and NFV developments that will shape the future of the networking industry. With this year’s event, taking place March 26-29, 2018 in Los Angeles, ONS will evolve its approach as the premier open source networking event. We’re excited to share three new aspects of this year’s ONS that you won’t want to miss:
  • AT&T contributes code to Linux open source edge computing project
    The Linux Foundation recently announced a new project, dubbed Akraino, to develop an open source software stack capable of supporting high-availability cloud services for edge computing systems and applications. To kick off the project, AT&T will contribute code made for carrier-scale edge computing applications running in virtual machines and containers.
  • AT&T Brings Akraino Networking Project to Edge of the Linux Foundation
    The Linux Foundation has been particularly busy in 2018 thus far consolidating its existing networking project under a single umbrella, known as LF Networking. That umbrella might need to get a bit larger, as on Feb. 20 the Linux Foundation announced the new Akraino project, with code coming initially from AT&T.

  • Getting Debian booting on a Lenovo Yoga 720
    I recently got a new work laptop, a 13” Yoga 720. It proved difficult to install Debian on; pressing F12 would get a boot menu allowing me to select a USB stick I have EFI GRUB on, but after GRUB loaded the kernel and the initrd it would just sit there never outputting anything else that indicated the kernel was even starting. I found instructions about Ubuntu 17.10 which helped but weren’t the complete picture. What seems to be the situation is that the kernel won’t happily boot if “Legacy Support” is not enabled - enabling this (and still booting as EFI) results in a happier experience.
  • Dell PowerEdge T30
    I just did a Debian install on a Dell PowerEdge T30 for a client. The Dell web site is a bit broken at the moment, it didn’t list the price of that server or give useful specs when I was ordering it. I was under the impression that the server was limited to 8G of RAM, that’s unusually small but it wouldn’t be the first time a vendor crippled a low end model to drive sales of more expensive systems. It turned out that the T30 model I got has 4*DDR4 sockets with only one used for an 8G DIMM. It apparently can handle up to 64G of RAM.
  • Quad-Ethernet SBC and controller tap new Renesas RZ/N1D SoC
    Emtrion’s Linux-ready “SBC-RZN1D” SBC, which will soon power a “Flex2COM” controller, features a Renesas dual-core -A7 RZ/N1D SoC and 4x LAN ports, and is designed for multi-protocol fieldbus communications. Emtrion, which recently announced its emCON-RZ/G1H module based on an octa-core Renesas RZ/G1H SoC, has unveiled a Renesas based, quad-LAN port SBC-RZN1D SBC focused on industrial communication. The SBC-RZN1D taps the Renesas RZ/N1D (R9006G032), one of a new line of RZ/N1D SoCs launched last year by Renesas for industrial multi-protocol communications. Renesas recently collaborated with Avnet to ship its own dual-Ethernet Renesas RZ/N1D Solution Kit (see farther below).
  • Postage-Stamp Linux
    There was a time when big operating systems ran on big iron. IBM, Data General, Burroughs, DEC, and other computer makers built big machines with big, blinking lights, and big price tags. They ran grown-up software and they supported multiuser operating systems. If you wanted a toy, you built a microcomputer. If you wanted a real machine for serious work, you bought a mainframe. Maybe a minicomputer, if it were for lesser tasks.

  • Radcom partners with Red Hat for NFV management
    Radcom announced it is collaborating with Red Hat to provide operators with a fully virtualized network visibility solution running on Red Hat OpenStack Platform. As operators transition to NFV, a critical first step is gaining end-to-end network visibility. This collaboration enables operators to attain cloud-native network visibility without the hassle of building their own private cloud infrastructure, the vendor said. Once the operator's transition to NFV matures, integration efforts with the NFV and MANO infrastructure can be simplified.

    In December, I received the happy news of an offer for a internship position at UNICEF in the Office of Innovation. The Office of Innovation drives rapid technological innovation by rapid prototyping of new ideas and building full-stack products to make a positive impact in the lives of children. This is a simple answer, but a more detailed description is on our website. My internship at UNICEF is unique: I support open source community engagement and research as my primary task for the MagicBox project. For years, I’ve done this in open source communities in my free time (namely SpigotMC and Fedora), but never in a professional role. As I navigate my way through this exciting opportunity, I plan to document some of the experience as I go through blogging. My intent is that my observations and notes will be useful to someone else in the humanitarian open source space (or maybe to a future me).

    DevOps, it has often been pointed out, is a culture that emphasizes mutual respect, cooperation, continual improvement, and aligning responsibility with authority.

This opens the request from the binary nature of "yes" and "no" toward having a nuanced discussion around priority, capacity, and responsibility.

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 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 [...]
