GNU/Linux on Laptops: Chrome OS and Pop_OS

  • Chrome OS Now Supports Linux Apps, But Only On Google Pixelbook

    In a stunning new development, Chrome OS now supports full-fledged Linux apps, with a preview available beginning May 8 for Google Pixelbook users.

    Being able to run Linux is a drastic addition to Chrome OS, Google's proprietary operating system, which up until now has only supported web-based Chrome apps and Android apps. The arrival of Linux marks the first time Chrome OS will be able to run full desktop applications.

    As VentureBeat reports, Chrome OS product management director Kan Liu says users can use Linux-based tools, editors, and integrated development environments on a Chromebook, and the installation process is similar to that on a typical Linux machine.

  • Cats and dogs living together, Linux on Chromium, mass hysteria ...

    First we find out that Microsoft's best selling server is running on Linux and now you will be able to run Debian flavoured Linux apps such as Linux terminal, Git, Sublime, Vim and Android Studio on the Pixelbook.  This should help bridge the gap between Chromium and its far more popular and capable sibling, Android.  According to The Inquirer, Google expects this to be a seamless integration without requiring extra steps to launch the apps.  Perhaps one day we will see these two OSes start to combine as both Microsoft and Google seem to have noticed the unpopularity of skinny versions of their operating systems.

  • System76 Galago Pro Linux laptop now has two screen size options

    Just yesterday, we shared the news that System76 had refreshed its popular Oryx Pro laptop. The Linux community was abuzz with excitement over the thinner and faster notebook. After all, it offers a lot of horsepower at a very affordable price. Heck, the battery life has even doubled compared to its predecessor!

    The computer seller is apparently not ready to slow down, however, as today it also refreshes its affordable and svelte Galago Pro Linux ultrabook. What's particularly exciting about the new model is that it has two screen sizes -- 13 inch HiDPI or 14 inch 1080p (in matte). Regardless of which you choose, the overall dimensions stay the same. How can that be, you ask? Well, for the 14 inch model, the bezels are just thinner.

    Hello everyone! A lot has happened behind the scenes since my last design report. Until now, I have been reporting on our design work mainly on the software front, but our effort is obviously not limited to that. The experience that people can have with their physical device is also very important. So in this post I will summarize some recent design decisions we have made both on the software side and the hardware product “experience” design.

  • VIA Joins In The AI Race, Linux/Android Support For Their New Developer Kit

KDE and GNOME: Cutelyst 2.3.0, Discovering Gwenview, First Look at GNOME’s Stylish New Login & Lock Screens

  • Cutelyst 2.3.0 released

    Cutelyst – The C++ Web Framework built with Qt, has a new release.

    In this release a behavior change was made, when asking for POST or URL query parameters and cookies that have multiple keys the last inserted one (closer to the right) is returned, previously QMap was filled in reverse order so that values() would have them in left to right order. However this is not desired and most other frameworks also return the last inserted value. To still have the ordered list Request::queryParameters(“key”) builds a list in the left to right order (while QMap::values() will have them reversed).

    Some fixes on FastCGI implementation as well as properly getting values when uWSGI FastCGI protocol was in use.

  • Discovering the Gwenview photo viewer

    The Gwenview photo viewer is a great application and one of the reasons why I never looked back when I switched from Windows (Vista) to openSUSE (11.1). The application is installed by default when you install openSUSE with the KDE plasma desktop environment. But even if you have the GNOME desktop environment installed, I would recommend that you to install Gwenview. In my opinion, it is superior to the GNOME image viewer application.

    Default applications often get overlooked. We just expect them to be there. But there are big differences when it comes to default applications. Take for instance the GNOME image viewer or Windows Photo Viewer. You can do a couple of basic things like zoom in, zoom out and move from photo to photo. You can put it in full screen mode and go back. And of course you can open, save, print and close photos. But that is basically it. Gwenview does a lot more.

    So lets get to it. There are basically 2 ways to open Gwenview. The first way is to (double) click a photo in the Dolphin file manager (another great default application). The second way is to open Gwenview via the kickoff menu, by typing in the name in the search box or by looking at the Graphics section of the menu.

  • Misunderstood Intel Documentation Leads to Multivendor Vulnerability

    Major operating system vendors including Microsoft, Apple and Linux distributions somehow misinterpreted Intel documentation about a hardware debugging feature and ended up exposing users to potential risk. 

    The flaw, which has been identified as CVE-2018-8897, was publicly reported on May 8, though impacted vendors were notified on April 30 and have already released patches. The flaw could have enabled an unauthenticated user to read sensitive data in memory or control low-level operating system functions.

    "In some circumstances, some operating systems or hypervisors may not expect or properly handle an Intel architecture hardware debug exception," CERT warned in its advisory on the issue. "The error appears to be due to developer interpretation of existing documentation for certain Intel architecture interrupt/exception instructions, namely MOV to SS and POP to SS."

  • Ubuntu Developers Once Again Debate Dropping i386 Images, Then Discontinuing i386 Port

    While the Ubuntu desktop official images are no longer 32-bit/i386 and more Ubuntu derivatives are dropping their 32-bit x86 installers, not all 32-bit images/installers have been discontinued and the i386 package archive / port remains. That matter though is back to being debated.

    As has been common to see every once in a while over the past few years, Ubuntu developers are back to debating the i386 status following the latest Ubuntu 18.04 LTS cycle. Canonical's Bryan Quigley is proposing that i386 be dropped -- initially for images/installers but with an end goal of dropping the i386 port.

  • Firefox Quantum, Bcachefs, Ubuntu, Devuan 2.0

    It would seem that the main Ubuntu distribution may not be the only *buntu to drop support for 32-bit x86 (i386) architectures. A proposal has just been put forth by Bryan Quigley to drop support for Lubuntu, Xubuntu, Kylin and Kubuntu.

    Now that we know the codename of the next Ubuntu release, Ubuntu 18.10, it's time to take a closer look at the release schedule, which suffered some changes for this cycle, and the proposed release date.

    Development on Ubuntu 18.10 (Cosmic Cuttlefish) kicked off officially earlier this week with the latest GCC (GNU Compiler Collection) 8.1 release, though it's not yet the default system compiler. However, Canonical plans to migrate from GCC 7, which is currently used in the latest Ubuntu 18.04 LTS (Bionic Beaver) release to the GCC 8.x series.

  • AFL in Ubuntu 18.04 is broken

    At is has been reported on the discussion list for American Fuzzy Lop lately, unfortunately the fuzzer is broken in Ubuntu 18.04 “Bionic Beaver”. Ubuntu Bionic ships AFL 2.52b, which is the current version at the moment of writing this blog post. The particular problem comes from the accompanying gcc-7 package, which is pulled by afl via the build-essential package. It was noticed in the development branch for the next Debian release by continuous integration (#895618) that introducing a triplet-prefixed as in gcc-7 7.3.0-16 (like same was changed for gcc-8, see #895251) affected the -B option in way that afl-gcc (the gcc wrapper) can’t use the shipped assembler (/usr/lib/afl-as) anymore to install the instrumentation into the target binary (#896057, thanks to Jakub Wilk for spotting the problem).

  • Linux sandboxing improvements in Firefox 60

    Continuing our past work, Firefox 60 brings further important improvements to security sandboxing on Linux, making it harder for attackers that find security bugs in the browser to escalate those into attacks against the rest of the system.

    The most important change is that content processes — which render Web pages and execute JavaScript — are no longer allowed to directly connect to the Internet, or connect to most local services accessed with Unix-domain sockets (for example, PulseAudio).

    This means that content processes have to follow any network access restrictions Firefox imposes — for example, if the browser has been set up to use a proxy server, connecting directly to the internet is no longer possible. But more important are the restrictions on connections to local services: they often assume that anything connecting to them has the full authority of the user running it, and either allow it to ask for arbitrary code to run, or aren't careful about preventing that. Normally that's not a security problem because the client could just run that code itself, but if it's a sandboxed Firefox process, that could have meant a sandbox escape.

    In case you encounter problems that turn out to be associated with this feature, the `security.sandbox.content.level` setting described previously can be used for troubleshooting; the network/socket isolation is controlled by level 4. Obviously we'd love to hear from you on Bugzilla too.

  • Switching to JSON for update manifests

    We plan on switching completely to JSON update manifests on Firefox and AMO. If you self-distribute your add-on please read ahead for details.

    AMO handles automatic updates for all add-ons listed on the site. For self-hosted add-ons, developers need to set an update URL and manage the update manifest file it returns. Today, AMO returns an RDF file, a common legacy add-on feature. A JSON equivalent of this file is now supported in Firefox. JSON files are smaller and easier to read. This also brings us closer to removing complex RDF parsing from Firefox code.

    Firefox 62, set to release September 5, 2018, will stop supporting the RDF variant of the update manifest. Firefox ESR users can continue using RDF manifests until the release of Firefox 68 in 2019. Nevertheless, all developers relying on RDF for their updates should read the documentation and switch soon. Firefox 45 introduced this feature, so all current versions of Firefox support it.

i.MX8 QuadMax module available in early access program

Filed under
Linux

Toradex has opened an early access program for sampling its Linux powered, wireless enabled Apalis iMX8 module, which offers NXP’s i.MX8 QuadMax SoC with 2x Cortex-A72, 4x -A53, 2x -M4F, and 2x GPU cores, supported with up to 4GB LPDDR4.

Toradex may have jumped the gun a bit when it announced the world’s first embedded board built on NXP’s i.MX8M QuadMax back in Mar. 2017. However, it may still end up being one of the first to reach market. The Swiss embedded technology firm just announced that it has “opened early access for selected customers” to the SODIMM-style Apalis iMX8 module. A sign-up form offers the potential for newcomers to get an early look. The only other announced module we’ve seen based on the hexacore SoC is iWave’s iW-RainboW-G27M 82 x 50mm SMARC module.

Read-Only Memory

Filed under
Linux

Igor Stoppa posted a patch to allow kernel memory pools to be made read-only. Memory pools are a standard way to group memory allocations in Linux so their time cost is more predictable. With Igor's patch, once a memory pool was made read-only, it could not be made read-write again. This would secure the data for good and against attackers. Of course, you could free the memory and destroy the pool. But short of that, the data would stay read-only.

There was not much controversy about this patch. Kees Cook felt that XFS would work well with the feature. And, having an actual user would help Igor clarify the usage and nail down the API.

This apparently had come up at a recent conference, and Dave Chinner was ready for Igor's patch. He remarked, "we have a fair amount of static data in XFS that we set up at mount time and it never gets modified after that. I'm not so worried about VFS level objects (that's a much more complex issue) but there is a lot of low hanging fruit in the XFS structures we could convert to write-once structures."
