Security
  • Security updates for Wednesday

    Security updates have been issued by CentOS (firefox and kernel), Debian (thunderbird), Fedora (curl), openSUSE (curl and python-Werkzeug), Oracle (kernel and thunderbird), Red Hat (rh-nginx114-nginx), SUSE (curl, ibus, MozillaFirefox, firefox-glib2, firefox-gtk3, openldap2, openssl, openssl1, python-urllib3, and util-linux and shadow), and Ubuntu (linux, linux-aws, linux-azure, linux-lts-trusty, linux-lts-xenial, linux-oracle, linux-raspi2, linux-snapdragon, and wpa).

  • SGX and security modules

    Software Guard Extensions (SGX) is a set of security-related instructions for Intel processors; it allows the creation of private regions of memory, called "enclaves". The aim of this feature is to work like an inverted sandbox: instead of protecting the system from malicious code, it protects an application from a compromised kernel hypervisor, or other application. Linux support for SGX has existed out-of-tree for years, and the effort of upstreaming it has reached an impressive version 22 of the patch set. During the upstreaming discussion, the kernel developers discovered that the proposed SGX API did not play nicely with existing security mechanisms, including Linux security modules (LSMs).

LWN Articles About Linux (Kernel): Linux Plumbers Conference, Staging, Linux Conference North America, Stable Statistics

Filed under
Linux
  • Topics from the Open Printing microconference

    On day two of the 2019 Linux Plumbers Conference, two of the principals behind the Open Printing project led the very first Open Printing microconference. Project leader Till Kamppeter and program manager Aveek Basu described the current state of printing on Linux and some of the plans for the future, including supporting scanning for multi-function devices. The picture they painted was rosy, at least for printing, which may not quite match the experience of many Linux users. As with many projects, though, Open Printing is starved for contributors—something that was reflected in the sparse attendance at the microconference.

    Basu began by pointing out that some attendees had likely printed their boarding passes from Linux, which highlights the importance of printing for Linux. People use it for bank documents, transport tickets, and more. He has been at Lexmark for 11 years, working on printing for Linux, macOS, and other Unix-based systems. Kamppeter said that he has been the Open Printing leader since 2001. The idea of the project is to do everything possible to make printing "just work" with Linux and other operating systems; the goal is "plug and print".

  • What happens to kernel staging-tree code

    The staging tree was added to the kernel in 2008 for the 2.6.28 development cycle as a way to ease the process of getting substandard device drivers into shape and merged into the mainline. It has been followed by controversy for just about as long. The recent disagreements over the EROFS and exFAT filesystems have reignited many of the arguments over whether the staging tree is beneficial to the kernel community or not. LWN cannot answer that question, but we can look into what has transpired in the staging tree in its first eleven years to see if there are any conclusions to be drawn there.

    The core idea behind the staging tree is that it is open to code that does not live up to the normal standards for inclusion into the kernel. Once a driver is added there, it is available to anybody who is brave enough to try to make use of it, but the real purpose is to allow developers to improve the code to the point that it is ready to go into the kernel proper. It serves as an easy place for new developers to try out simple changes and, when it works well, it helps the kernel to gain hardware support that might otherwise languish out-of-tree indefinitely.

  • The USB debugging arsenal

    At the 2019 Embedded Linux Conference North America, which was held in San Diego in August, Krzysztof Opasiak gave a presentation on demystifying the ways to monitor—and even change—USB traffic on a Linux system. He started with the basics of the USB protocol and worked up into software and hardware tools to observe, modify, and fuzz the messages that get sent. Those tools are part of the arsenal that is available to those interested in looking deeply into USB.

    Opasiak works in Poland for what he called a "small Korean company" (Samsung). He noted that it is not that easy to sniff USB traffic and that the ways to do so are not well known. But "there are no dragons"; nothing bad will happen if you do so. In some ways, USB is like the internet and some of the same tools can be used for both.

  • 5.3 Kernel development cycle statistics

    It's that time of the development cycle again: work on the 5.3 kernel is winding down with an expected final release date of September 15. Read on for LWN's traditional look at where the code in 5.3 came from in this relatively busy development cycle.
    As of this writing, 14,435 non-merge changesets have been pulled into the mainline repository for 5.3; these changes were contributed by 1,846 developers

Kmdr – Display CLI Commands Explanation In Terminal

Filed under
Software

A while ago, we wrote about ExplainShell, a web-based tool to learn what each part of a Linux command does. It divides the complex and lengthy Linux commands into multiple parts and gives explanation for each part. Using this tool, a Linux newbie can learn about various command line parameters and options without having to refer man pages. However, It will only help you to learn Linux commands. But what if you want to learn other CLI commands, for example Python? You won’t find explanation of Python commands in ExplainShell. No worries! Today, I stumbled upon a similar tool named Kmdr that provides CLI commands explanation for hundreds of programs. It helps you to easily learn CLI commands without leaving the terminal and without having to go through lengthy man pages. Not just Linux commands, Kmdr provides explanation for a lot of CLI commands including ansible, conda, docker, git, go, kubectl, mongo, mysql, npm, ruby gems, vagrant and hundreds of other programs such as those built into bash.

  • CF Summit Panel Discussion: Cloud Foundry Test Kitchen

    At the recent Cloud Foundry Summit EU in the Netherlands, Jeff Hobbs of SUSE participated in a re-named “Will it Blend?” panel discussion, talking about whether Kubernetes is the future of Cloud Foundry and how other technologies could potentially be integrated. It seems that Kubernetes and Cloud Foundry did indeed blend and the future is looking bright!

    Cloud Foundry Foundation has posted all recorded talks from CF Summit EU on YouTube. Check them out if you want to learn more about what is happening in the Cloud Foundry world! I’ll be posting more SUSE Cloud Application Platform talks here over the coming days. Watch Vlad’s talk below:

  • FOSDEMs bespoke video hardware and software.

    You can see the white hdmi cable running from the lime2 hdmi out to the monitor. This old monitor is my test "projector", the fact that it is 4:3 makes it a good test subject.

    You can also see a black cable from the capture board to another blue board with a red led. This is a banana-pi M1 as this is the current SBC being used in the FOSDEM video boxes, and i had one lying around anyway, doing nothing. It spews out a test image.

    What you are seeing here is live captured data at 1280x720@60Hz, displayed on the monitor, and in the background of the status LCD, with a 1 to 2 frame delay.

  • Ubucon Europe 2019: Ubucon talks schedule is live!

    It is now 3 weeks before Ubucon starts, and what better way to remind everyone that we are ready to go by showing our full schedule!

    Don’t forget to register to our pre-ubucon cultural events if you want to know a little bit more of Sintra, and don’t forget as well to register for the event if you would like to receive some swag!

    All of this would not be possible without the support of our sponsors and the participation of volunteers and speakers for which we are very grateful.

  • Qt Contributors' Summit 2019

    The Qt Contributors' Summit is an annual event open to anyone who has contributed toward the Qt project in the past year. Contributions can include code, helping on the forum, maintaining the wiki, or any other form of moving the Qt project forward.

    After visiting beautiful Oslo in June last year, we invite you this year to the premises of The Qt Company in Berlin-Adlershof. And because of Qt 6 on the horizon, we have extended the event to three days! The first day will be all about sharing a common vision, while the following two days will be organized as an Unconference. We will have plenty of space to allow you to meet, collaborate, and get stuff done.

Samba 4.11

Filed under
Software
  • Samba 4.11.0 Available for Download
    Samba 4.11 has changed how the AD database is stored on disk. AD users should
    not really be affected by this change when upgrading to 4.11. However, AD
    users should be extremely careful if they need to downgrade from Samba 4.11 to
    an older release.
    
    Samba 4.11 maintains database compatibility with older Samba releases. The
    database will automatically get rewritten in the new 4.11 format when you
    first start the upgraded samba executable.
    
    However, when downgrading from 4.11 you will need to manually downgrade the AD
    database yourself. Note that you will need to do this step before you install
    the downgraded Samba packages. For more details, see:
    https://wiki.samba.org/index.php/Downgrading_an_Active_Directory_DC
    
    When either upgrading or downgrading, users should also avoid making any
    database modifications between installing the new Samba packages and starting
    the samba executable.
    
  • Samba 4.11 Released With Much Better Scalability While Disabling SMB1 By Default

    Samba 4.11 is out as the latest big feature update to this SMB/CIFS/AD implementation for offering better Windows interoperability with Linux and other platforms. The changes in Samba 4.11 are aplenty that we are a bit surprised it wasn't called Samba 5.0.

    Perhaps most exciting is Samba 4.11 having big scalability improvements to the point that it should be able to scale to 100,000+ users.

  • AMD EPYC 7H12 Announced As New 280 Watt Processor For High Performance Computing

    From Rome, Italy this afternoon AMD not only announced more than 100 world records have been broken with their new EPYC "Rome" processors, but there is also a new SKU! Meet the EPYC 7H12.

    The EPYC 7H12 doesn't quite follow the naming convention of the rest of the EPYC Rome line-up announced back in August as it's a special part. The EPYC 7H12 is more akin to Intel's Cascadelake-AP line-up but with more broad availability and just a higher clocked / higher power part as opposed to tacking on extra dies. But it carries the same focus on delivering maximum HPC performance.

  • Nvidia Open Sources Its Deep Learning Compiler

  • NVIDIA Bringing Up Open-Source Volta GPU Support For Their Xavier SoC

    While NVIDIA doesn't contribute much open-source Linux driver code as it concerns their desktop GPUs (though they have been ramping up documentation), when it comes to Tegra/embedded is where they have contributed improvements and new hardware support to Nouveau and associated driver code in the past several years. NVIDIA's open-source Tegra/embedded contributions come as a result of customer demand/requirements. Their latest work is preparing to finally bring-up the "GV11B" Volta graphics found within last year's Tegra Xavier SoC.

  • Valve's ACO Shader Compiler Under Review For The Mesa Radeon Vulkan Driver

    The RADV "ACO" shader compiler announced by Valve back in July for the fastest compilation speeds and best possible code generation may soon be hitting mainline Mesa for the open-source AMD Linux graphics stack.

    The ACO shader compiler as an alternative to the existing AMDGPU LLVM shader compiler back-end has shown quite promising results for Linux games. ACO has become more featureful over time and is now largely at feature parity to the existing shader compilation support while generally offering some performance advantages, thanks to the effort and funding by Valve.

  • Noodlings | Commander X16, BDLL and openSUSE News

    The mission of the computer. Similar to the Commodore 64 but made with off the shelf components. As far as the architecture goes, it is actually closer to the VIC-20 on board design but far, far more capable. I am rarely excited about new things, I like my old computers and really existing technology. I tend to drag my heels at the very thought of getting something new. This, for whatever reason gets me excited and I can’t exactly put my finger on it.

    This all started out as a kind of pondering in 2018 and in February 2019 with a video from David Murray, the 8-bit Guy’s Dream Computer. the discussion started by the 8-bit Guy

    The initial design started with the Gameduino for the video chip which had some technical hurdles and was based on an obsolete, as in, no longer supported, chip that doesn’t have a large pool of developers and hackers working on it.

    After some discussions and planning, it was decided to base it largely off of the VIC-20 as most of the chips are still available today and it is a known working design. Some of the changes would be a faster processor, better video and better sound components.

    Mozilla will turn the Firefox crank faster in 2020, releasing a new version of its web browser every four weeks instead of every six. If you're using the browser, the change should deliver new features to you faster since there will be less waiting between when developers build them and when they arrive.

    "In recent quarters, we've had many requests to take features to market sooner. Feature teams are increasingly working in sprints that align better with shorter release cycles. Considering these factors, it is time we changed our release cadence," Firefox team members Ritu Kothari and Yan Or said in a blog post Tuesday. "Shorter release cycles provide greater flexibility to support product planning and priority changes due to business or market requirements."

Debian May Need To Re-Evaluate Its Interest In "Init System Diversity"

Filed under
Debian

Debian Project Leader Sam Hartman has shared his August 2019 notes where he outlines the frustrations and issues that have come up as a result of init system diversity with some developers still aiming to viably support systemd alternatives within Debian.

Stemming from elogind being blocked from transitioning to testing and the lack of clarity into that, Hartman was pulled in to try to help mediate the matter and get to the bottom of the situation with a lack of cooperation between the elogind and systemd maintainers for Debian as well as the release team. Elogind is used by some distributions as an implementation of systemd's logind, well, outside of systemd as a standalone daemon. Elogind is one of the pieces to the puzzle for trying to maintain a modern, systemd-free Linux distribution.

  • Linux 5.4 Power Management Updates Sent In But Without AMD CPPC Changes

    The Linux 5.4 power management changes have been submitted for this next version of the Linux kernel.

    This time around the power management work isn't particularly exciting with no breakthroughs for the Intel P-State driver, no major changes to the other prominent CPUFreq drivers/governors, and no AMD CPPC support for their new processors.

  • Linux 5.4 Preps For Intel Tiger Lake, Elkhart Lake & Lightning Mountain + Killing MPX

    The Linux 5.4 x86/cpu changes are as busy as always on the Intel side.

    The Linux 5.4 x86/cpu code changes include cleaning up the Intel CPU naming conventions within definitions in the code. The changes now provide a standardized convention for dealing with Intel CPU core names and their variations within the kernel code rather than the naming convention mess that had come about over the years. This doesn't impact end-users, but cleans up the kernel code to be less confusing.

  • Microsoft exFAT File-System Mailed In For Linux 5.4 Along With Promoted EROFS & Greybus

    Greg Kroah-Hartman began volleying his Linux 5.4 kernel pull requests today of the subsystems he oversees. The most significant of this morning's pull requests are the staging area changes that include the Microsoft exFAT file-system support.

    As we've been expecting, Linux 5.4 is bringing exFAT support after last month's surprise announcement by Microsoft publishing the exFAT specification and giving it an open-source blessing for integrating the file-system support at long last into the Linux kernel.

  • Improved Fscrypt Sent In For Linux 5.4 To Offer Better Native File Encryption Handling

    In addition to submitting the FS-VERITY file authentication code for Linux 5.4, Google's Eric Biggers has sent out his big update to the fscrypt file encryption framework for this next kernel revision.

    Fscrypt as a reminder is a kernel framework providing native file encryption support to file-systems. Currently Fscrypt is used by EXT4, F2FS, and UBIFS while being used by Google for at least new Android use-cases. Fscrypt has been around for several kernel cycles now but for Linux 5.4 is seeing its first big update.

Ubuntu

Canonical announces full enterprise support for Kubernetes 1.16, with support covering Charmed Kubernetes, MicroK8s and kubeadm.

MicroK8s will be updated with Kubernetes 1.16 enabling users access to the latest upstream release with a single-line command in under 60 seconds. In addition, MicroK8s gets new add-ons with one line installs of Helm and Cilium as well as enhancements, upgrades and bug fixes. Cilium adds enhanced networking features including Kubernetes Network Policy support. With MicroK8s 1.16, users can develop and deploy enterprise grade Kubernetes on any Linux desktop, server or VM across 42 Linux distros.

Canonical’s Charmed Kubernetes 1.16 will come with exciting changes like support for Kata Containers, AWS IAM, SSL passthrough and more. Using Kata Containers, insecure or untrusted pods can be run safely in isolation without disrupting trusted pods in deployments. Identity Access Management on AWS can be used to login to your Charmed Kubernetes cluster. Users get more control over their deployments while benefitting from reduced complexity due to improved LXD support and enhanced Prometheus and OpenStack integration.

“At Canonical, we enable enterprises by reducing the complexity of their Kubernetes deployments. We are actively involved in the Kubernetes community to ensure we listen to, and support our users’ and partners’ needs. Staying on top of security flaws, community issues and features to improve Kubernetes is critical to us. We keep the Ubuntu ecosystem updated with the latest Kubernetes, as soon as it becomes available upstream,” commented Ammar Naqvi, Product Manager at Canonical.

Linux Distribution Comparison

Linux

There are currently nearly 300 active Linux distributions, which makes choosing just one somewhat difficult, especially if you would rather make your own informed decision instead of relying on the recommendation of someone else. The good news is that the number of major Linux distributions, which stand out in a significant way and are more than simple reskins of existing distributions, is much smaller.
If we were to represent the world of Linux distribution as a map, the 10 distributions listed in this article would be the continents of the world, while other distributions would be islands of various sizes. Just like there is no “best” continent in the real world, the same holds true in the world of Linux distributions.

Each Linux distribution is designed with a different use case in mind, and the same distribution can be perfect for one user and unusable for another one. That’s why the distributions in this article aren’t listed in any particular order and are numbered just for the sake of convenience.

Intel Icelake Thunderbolt Support, Stratix10 Additions & Other Material Hits Linux 5.4

The "char/misc" changes for the Linux 5.4 are as eventful as ever. Greg Kroah-Hartman sent in the char/misc changes earlier this week for the Linux 5.4 merge window that's now half-way through. The since merged material contains a lot of notable hardware support improvements. Exciting us the most is that the Intel Icelake Thunderbolt support is now squared away. Intel had most of the Icelake CPU support in good shape going back months including for the Gen11 graphics, but the Thunderbolt support was the last holdout. With Icelake, the Thunderbolt controller has moved onto the CPU package itself sans the power deliver infrastructure. These changes yielded additional work to get Icelake Thunderbolt support going under Linux, but it's finally there for Linux 5.4 with Icelake laptops beginning to hit retail channels. Read more

Geary 3.34 Debuts with Deeper GNOME Contacts Integration, Other Changes

The Geary email client has issued a brand new release, and in this post I tell you a bit about it. Geary 3.34.0 — you may recall that Geary switched to following GNOME numbering last year — is the latest update to this web-mail friendly mail tool, and there’s healthy dose of improvement on offer, as noted in the release notes.
