Linux Kernel 4.15 Delayed

  • Linux Kernel 4.15 Delayed Until Next Week as Linus Torvalds Announces a Rare RC9

    While the Linux community was looking forwards to the final Linux 4.15 kernel release today, Linus Torvalds just delayed it for another week, announcing the ninth Release Candidate (RC) instead.

    It's not every day that you see a ninth Release Candidate in the development cycle of a new Linux kernel branch, but here we go, and we can only blame it on those pesky Meltdown and Spectre security vulnerabilities that affect us all, putting billions of devices at risk of attacks.

  • Linux 4.15 becomes slowest release since 2011

    Linus Torvalds has decided that Linux 4.15 needs a ninth release candidate, making it the first kernel release to need that much work since 2011.

    Torvalds flagged the possibility of an extra release candidate last week, with the caveat that “it obviously requires this upcoming week to not come with any huge surprises” after “all the Meltdown and Spectre hoopla” made his job rather more complicated in recent weeks.

    Fast-forward another week and Torvalds has announced “I really really wanted to just release 4.15 today, but things haven't calmed down enough for me to feel comfy about it”.

  • No 4.15 final release today

    As might have been expected from watching the commit stream, the 4.15 kernel is not ready for release, so we'll get 4.15-rc9 instead. Linus said: "I really really wanted to just release 4.15 today, but things haven't calmed down enough for me to feel comfy about it, and Davem tells me he still has some networking fixes pending. Laura Abbott found and fixed a very subtle boot bug introduced this development cycle only yesterday, and it just didn't feel right to say that we're done."

Linus Torvalds Calls Linux Patch for Intel CPUs "Complete and Utter Garbage"

Filed under
Linux

The patch submitted by David Woodhouse, ex-Intel kernel engineer that now works for Amazon described a so-called new feature for Intel processors to address Indirect Branch Restricted Speculation (IBRS) by creating macros that would restrict or unrestrict Indirect Branch Speculation based on if the Intel CPU will advertise "I am able to be not broken."

The "x86/enter: Create macros to restrict/unrestrict Indirect Branch Speculation" feature implies that the IBRS (Indirect Branch Restricted Speculation) bit needed to be set at boot time to "ask" the processor not to be broken. Linus Torvalds immediately reacted to the patch calling it "complete and utter garbage" despite the developer's efforts to explain why he implemented the nasty hack.

Reviews

Long-time readers of the Linux distribution reviews on this blog know that I am a fan of Linux Mint, but I have had somewhat mixed experiences with KDE. When I've reviewed a new release of Linux Mint, I have occasionally reviewed its KDE edition in addition to its GNOME/MATE/Cinnamon and Xfce editions, generally finding that the KDE edition has too many minor bugs and not enough compelling features compared to the more mainstream editions. Apparently the Linux Mint developers feel similarly, as this is the last release of a KDE edition for Linux Mint; henceforth, they are only releasing MATE, Cinnamon, and Xfce editions for a tighter focus on GTK-based DEs and applications. With that in mind, I figured it was worth reviewing a KDE edition of Linux Mint one final time. I tested it on a live USB system made with the "dd" command. Follow the jump to see what it's like.

Raspberry Pi Alternatives

Filed under
Linux

The phenomenon behind the Raspberry Pi computer series has been pretty amazing. It's obvious why it has become so popular for Linux projects—it's a low-cost computer that's actually quite capable for the price, and the GPIO pins allow you to use it in a number of electronics projects such that it starts to cross over into Arduino territory in some cases. Its overall popularity has spawned many different add-ons and accessories, not to mention step-by-step guides on how to use the platform. I've personally written about Raspberry Pis often in this space, and in my own home, I use one to control a beer fermentation fridge, one as my media PC, one to control my 3D printer and one as a handheld gaming device.

  • Octogenarianhood

    2018 began for me with an absolutely incredible 80th birthday celebration called Knuth80, held in the delightful city of Piteå in northern Sweden. It's impossible for me to thank adequately all of the wonderful people who contributed their time to making this event such a stunning success, certainly one of the greatest highlights of my life. Many of the happenings were also captured digitally in state-of-the-art audio and video, so that others will be able to share some of this joy. I'll link to that data when it becomes available.

    Rcpp has become the most popular way of enhancing GNU R with C or C++ code. As of today, 1288 packages on CRAN depend on Rcpp for making analytical code go faster and further, along with another 91 in BioConductor.

Security: Updates and Botched Updates

  • RedHat reverts patches to mitigate Spectre Variant 2

    RedHat previously released patches to mitigate this issue, however, in a rather controversial move, has decided to roll back these changes after complaints about systems failing to boot with the new patches, and instead is now recommending that, "subscribers contact their CPU OEM vendor to download the latest microcode/firmware for their processor."

  • Red Hat dumps Spectre CPU patches that brick servers

    Enterprise Linux vendor Red Hat will no longer distribute microcode patches to mitigate against the Spectre processor flaw after bugs in the patches stopped user systems from booting up.

    The company advised of its decision late last week after being alerted by its customers to problems with the patches.

    Red Hat is now reverting the microcode_ctl and linux-firmware packages it includes with its enterprise Linux distribution to older versions that are known to be stable.

    Microcode, also known as millicode and firmware, is software distributed by vendors to correct specific errors for processors.

  • This is Why you Must Consider Open-Source IoT Solutions

    The Internet of things is growing exponentially. Its applications are unique and that is one of the reasons that this technology has become renowned. Organizations are finding ways to utilize this technology for improving their workforce, while AI impacts IoT to create smarter applications. Making use of IoT seems to be costlier for companies who are still in their infancy phase. For companies like these, open-source IoT solutions have been created so that they too can reap the benefits of IoT as a technology.

  • Ellcrys is a Breath of Fresh Air for Open Source Collaborators

    Ellcrys is an up and coming blockchain network that aims to revolutionize the way developers work together. In addition to trying to revitalize collaborative efforts, the company has an ICO that promises to make the mining and distribution of its native cryptocurrency fairer and more accessible.

  • Genode OS Framework Making Plans For 2018

    The Genode open-source operating system framework project has shared some of their planned goals for 2018.

    Genode in 2018 is looking to advance their "Sculpt" general purpose system scenario for the operating system. Back during the Genode OS 17.11 release they described Sculpt as "the approach to start with a minimalistic generic live system that can be interactively shaped into a desktop scenario by the user without any reboot. This is made possible by combining Genode's unique dynamic reconfiguration concept with the recently introduced package management, our custom GUI stack, and the many ready-to-use device-driver components that we developed over the past years."

Ubuntu

Ubuntu MATE 17.10 is a solid release with a few minor caveats about the Mutiny layout. The Traditional MATE layout is very nice, but Mutiny still needs some work. For users who want the classic GNOME 2 look-and-feel, Ubuntu MATE is an excellent choice. However, Unity users looking for a Unity-like experience should still give Ubuntu MATE with the Mutiny layout a try, but need to be aware that it does have some issues and it won't work exactly like Unity. The Contemporary layout is also an option for Unity users, but is even further removed from the Unity experience than Mutiny is.

Our Favourite Apps for Ubuntu

Filed under
Ubuntu

We enjoy using Ubuntu mainly for gaming, writing, listening to music and browsing the web. (Lots and lots of browsing the web.) There are other apps that we would love to have on Ubuntu like Affinity Photo, a stunning image editor that’s on par with Adobe’s Photoshop that’s available on Windows and Mac as well as Bear, a beautifully designed note taking app that we do most of our writing on that’s only available for macOS.

However, the Ubuntu platform has moved forward in leaps and bounds in recent years when it comes to the official availability of popular apps and we are confident that this trend will continue.

Some FreeBSD Users Are Still Running Into Random Lock-Ups With Ryzen

Filed under

While Linux has been playing happily with Ryzen CPUs as long as you weren't affected by the performance marginality problem where you had to swap out for a newer CPU (and Threadripper and EPYC CPUs have been running splendid in all of my testing with not having any worries), it seems the BSDs (at least FreeBSD) are still having some quirks to address.

This week on the FreeBSD mailing list has been another thread about Ryzen issues on FreeBSD. Some users are still encountering random lockups that do not correspond to any apparent load/activity on the system.
