  • KRACK Vulnerability: What You Need To Know

    This week security researchers announced a newly discovered vulnerability dubbed KRACK, which affects several common security protocols for Wi-Fi, including WPA (Wireless Protected Access) and WPA2. This is a bad vulnerability in that it likely affects billions of devices, many of which are hard to patch and will remain vulnerable for a long time. Yet in light of the sometimes overblown media coverage, it’s important to keep the impact of KRACK in perspective: KRACK does not affect HTTPS traffic, and KRACK’s discovery does not mean all Wi-Fi networks are under attack. For most people, the sanest thing to do is simply continue using wireless Internet access.

Anarchy Linux Dispels Fear of Arch

Filed under
Linux
Reviews

Arch-Anywhere/Anarchy Linux is one of the nicest Arch-based distributions I have encountered. However, Anarchy Linux still requires familiarity with terminology and processes that usually are not needed to install Linux distros from a fully-functioning live session installation disk. Not having a demo mode to preview how the OS runs on your particular hardware can be a time-consuming setback.

However, once you have Anarchy Linux up and running, it will give you a very pleasing computing experience. Much of what happens after installation depends on the desktop environment you selected.

If you have a desktop preference or prefer one of the included window manager environments instead, you can forget about the sullied reputation that comes with Arch Linux distros. For many reasons, Anarchy Linux is a winning choice.

Why it's pointless to criticize Amazon for being 'bad' at open source

Filed under
OSS

Apparently AWS is B-A-D because it's a net consumer of open source software. You know, like every single company on earth, inside or outside of tech, probably even including Red Hat. The simple truth is that everyone consumes far more open source software than they contribute. It's just how the world works.

For those trying to keep score, however, and paint Amazon Web Services (AWS) as a bad open source citizen, the question is "Why?" Accusations of open source parsimony don't seem to have damaged developers' love for AWS as a platform, so exactly what are critics hoping to accomplish? Is it simply a matter of "paying a tax," as some suggest? If we've been reduced to inventing taxes to be paid, with no apparent reason for imposing them, we're doing open source wrong.

Running Android on Top of a Linux Graphics Stack

Filed under
Android
Linux
Interviews

Traditional Linux graphics systems (like X11) mostly did not use planes. But modern graphics systems like Android and Wayland can take full advantage of it.

Android has the most mature implementation of plane support in HWComposer, and its graphics stack is a bit different from the usual Linux desktop graphics stack. On desktops, the typical compositor just uses the GPU for all composition, because this is the only thing that exists on the desktop.

Most embedded and mobile chips have specialized 2D composition hardware that Android is designed around. The way this is done is by dividing the things that are displayed into layers, and then intelligently feeding the layers to hardware that is optimized to handle layers. This frees up the GPU to work on the things you actually care about, while at the same time, it lets hardware that is more efficient do what it does best.

Ubuntu 17.10: Hands-on with Artful Aardvark

Filed under
Reviews
Ubuntu

Ubuntu 17.10, Artful Aardvark, has now been officially released. I have not been much of an Ubuntu fan for a long time now, but this release includes a lot of significant changes, many of which might address some of my most serious objections about Ubuntu. So I think I should take a closer look at it than I normally do.

The release announcement mentions the major updates and changes - including the biggest of all, the switch from Unity back to Gnome 3 / Gnome Shell for the desktop. As I have not liked Unity from the very first time I saw it (that's a polite way to phrase it), I am very, very pleased with this change.

The release notes (for all versions) give a more complete list of packages updated, and a list of known issues. It also includes a statement that I know some users will not be pleased with:

Fedora: Fedora Workstation and Fedora Council

  • Looking back at Fedora Workstation so far

    So I have over the last few years blogged regularly about upcoming features in Fedora Workstation. Well I thought as we putting the finishing touches on Fedora Workstation 27 I should try to look back at everything we have achieved since Fedora Workstation was launched with Fedora 21. The efforts I highlight here are efforts where we have done significant or most development. There are of course a lot of other big changes that has happened over the last few years by the wider community that we leveraged and offer in Fedora Workstation, examples here include things like Meson and Rust. This post is not about those, but that said I do want to write a post just talking about the achievements of the wider community at some point, because they are very important and crucial too. And along the same line this post will not be speaking about the large number of improvements and bugfixes that we contributed to a long list of projects, like to GNOME itself. This blog is about taking stock and taking some pride in what we achieved so far and major hurdles we past on our way to improving the Linux desktop experience.

  • Resigning from Fedora Council for Fedora 27

    Since I became a Fedora contributor in August 2015, I’ve spent a lot of time in the community. One of the great things about a big community like Fedora is that there are several different things to try out. I’ve always tried to do the most help in Fedora with my contributions. I prefer to make long-term, in-depth contributions than short-term, “quick fix”-style work. However, like many others, Fedora is a project I contribute to in my free time. Over the last month, I’ve come to a difficult realization.

LWN on Linux: LTS, API, Pointer Leaks and Linux Plumbers Conference (LPC)

  • Cramming features into LTS kernel releases
    While the 4.14 development cycle has not been the busiest ever (12,500 changesets merged as of this writing, slightly more than 4.13 at this stage of the cycle), it has been seen as a rougher experience than its predecessors. There are all kinds of reasons why one cycle might be smoother than another, but it is not unreasonable to wonder whether the fact that 4.14 is a long-term support (LTS) release has affected how this cycle has gone. Indeed, when he released 4.14-rc3, Linus Torvalds complained that this cycle was more painful than most, and suggested that the long-term support status may be a part of the problem. A couple of recent pulls into the mainline highlight the pressures that, increasingly, apply to LTS releases. As was discussed in this article, the 4.14 kernel will include some changes to the kernel timer API aimed at making it more efficient, more like contemporary in-kernel APIs, and easier to harden. While API changes are normally confined to the merge window, this change was pulled into the mainline for the 4.14-rc3 release. The late merge has led to a small amount of grumbling in the community.
  • Improving the kernel timers API
    The kernel's timer interface has been around for a long time, and its API shows it. Beyond a lack of conformance with current in-kernel interface patterns, the timer API is not as efficient as it could be and stands in the way of ongoing kernel-hardening efforts. A late addition to the 4.14 kernel paves the way toward a wholesale change of this API to address these problems.
  • What's the best way to prevent kernel pointer leaks?
    An attacker who seeks to compromise a running kernel by overwriting kernel data structures or forcing a jump to specific kernel code must, in either case, have some idea of where the target objects are in memory. Techniques like kernel address-space layout randomization have been created in the hope of denying that knowledge, but that effort is wasted if the kernel leaks information about where it has been placed in memory. Developers have been plugging pointer leaks for years but, as a recent discussion shows, there is still some disagreement over the best way to prevent attackers from learning about the kernel's address-space layout. There are a number of ways for a kernel pointer value to find its way out to user space, but the most common path by far is the printk() function. There are on the order of 50,000 printk() calls in the kernel, any of which might include the value of a kernel pointer. Other places in the kernel use the underlying vsprintf() mechanism to format data for virtual files; they, too, often leak pointer values. A blanket ban on printing pointer values could solve this problem — if it could be properly enforced — but it would also prevent printing such values when they are really needed. Debugging kernel problems is one obvious use case for printing pointers, but there are others.
  • Continuous-integration testing for Intel graphics
    Two separate talks, at two different venues, give us a look into the kinds of testing that the Intel graphics team is doing. Daniel Vetter had a short presentation as part of the Testing and Fuzzing microconference at the Linux Plumbers Conference (LPC). His colleague, Martin Peres, gave a somewhat longer talk, complete with demos, at the X.Org Developers Conference (XDC). The picture they paint is a pleasing one: there is lots of testing going on there. But there are problems as well; that amount of testing runs afoul of bugs elsewhere in the kernel, which makes the job harder. Developing for upstream requires good testing, Peres said. If the development team is not doing that, features that land in the upstream kernel will be broken, which is not desirable. Using continuous-integration (CI) along with pre-merge testing allows the person making a change to make sure they did not break anything else in the process of landing their feature. That scales better as the number of developers grows and it allows developers to concentrate on feature development, rather than bug fixing when someone else finds the problem. It also promotes a better understanding of the code base; developers learn more "by breaking stuff", which lets them see the connections and dependencies between different parts of the code.

An update on GnuPG

The GNU Privacy Guard (GnuPG) is one of the fundamental tools that allows a distributed group to have trust in its communications. Werner Koch, lead developer of GnuPG, spoke about it at Kernel Recipes: what's in the new 2.2 version, when older versions will reach their end of life, and how development will proceed going forward. He also spoke at some length on the issue of best-practice key management and how GnuPG is evolving to assist. It is less than three years since attention was focused on the perilous position of GnuPG; because of systematic failure of the community to fund its development, Koch was considering packing it all in. The Snowden revelations persuaded him to keep going a little longer, then in the wake of Heartbleed there was a resurgent interest in funding the things we all rely on. Heartbleed led to the founding of the Core Infrastructure Initiative (CII). A grant from CII joined commitments from several companies and other organizations and an upsurge in community funding has put GnuPG on a more secure footing going forward. Read more

Ubuntu: GNOME, New Video, Ubuntu Podcast, Refreshing the Xubuntu Logo

  • Ubuntu 17.10: We're coming GNOME! Plenty that's Artful in Aardvark, with a few Wayland wails
    Ubuntu has done a good job of integrating a few plugins that improve GNOME's user experience compared to stock GNOME – most notably a modified version of the Dash-to-Dock and the App Indicator extensions, which go a long way toward making GNOME a bit more like Unity. It's worth noting that Ubuntu's fork of Dash-to-Dock lacks some features of the original, but you can uninstall the Ubuntu version in favour of the original if you prefer. In fact you can really revert to a pretty stock GNOME desktop with just a few tweaks. Canonical said it wasn't going to heavily modify GNOME and indeed it hasn't.
