LLVM Clang Moves A Bit Closer To Compiling The Linux 3.16 Kernel

Filed under
Development
Linux
BSD

The latest Linux 3.16 kernel pull request worth covering on Phoronix are the latest LLVMLinux patches for being able to compile the kernel with Clang rather than GCC.

With Linux 3.15 came the patch-set to come close to being able to compile under Clang and now with Linux 3.16 it's a bit closer. A set of five LLVMLinux patches are called for merging that affect ARM and Shash Crypto code.

From pre-history to beyond the global thermonuclear war

Filed under
Development
Linux

This is a short and vague glimpse to the interfaces that the Linux kernel offers to user space for display and graphics management, from the history to what is hot and new, to what might perhaps be coming after. The topic came current for me when I started preparing Weston for global thermonuclear war.

10 essential upgrades for your Raspberry Pi

Filed under
Development

If you’re anything like us – and dear Lord we hope you are not – you sometimes sit staring at your Raspberry Pi, willing it to do more. Unfortunately our mental prowess is not powerful enough to materialise extra features or tweak the performance of the ARM chip, so we instead turned to the internet and looked for ways to upgrade our Pi.

We came away with ten items that can help make your Raspberry Pi usage just that little bit better; from the simplest of USB cable switches to full-on touch screen LCD displays for the Pi. We then wrote a feature about it which you can read all about in the latest issue of Linux User & Developer.

GTK+ 3.13.2 Arrives with Interactive Debugging and Gestures Support

Filed under
Development

This latest update for GTK arrives with a multitude of changes and new features, but this is understandable because this is a development release.

According to the changelog, interactive debugging support has been implemented, gesture support has finally landed, the GTK+ widgets can now draw outside their allocation zone, by setting a clip with gtk_widget_set_clip(), GtkStack has added a few more transition types, and the GtkProgressBar is now narrower.

Building The Linux Kernel With LLVM's Clang Yields Comparable Performance

Filed under
Development
Graphics/Benchmarks
Linux
BSD

We have covered the LLVMLinux project many times with an increasing number of developers from the x86 and ARM world being interested in building the kernel with Clang. Among the reasons for wanting to build the Linux kernel with Clang is for possible performance advantages, faster kernel compilation times when debugging the kernel, using Clang's static analysis abilities on the kernel code itself, improving the quality of LLVM and Clang by finding missing/broken compiler features, and improving the overall code quality of the Linux kernel by making the code compatible with more compilers.

Git v2.0.0: Released

Filed under
Development

The latest feature release Git v2.0.0 is now available at the
usual places.

We had to delay the final release by a week or so because we found a
few problems in earlier release candidates (request-pull had a
regression that stopped it from showing the "tags/" prefix in
"Please pull tags/frotz" when the user asked to compose a request
for 'frotz' to be pulled; a code path in git-gui to support ancient
versions of Git incorrectly triggered for Git 2.0), which we had to
fix in an extra unplanned release candidate.

  • Rust pattern: Precise closure capture clauses
    This is the second in a series of posts about Rust compiler errors. Each one will talk about a particular error that I got recently and try to explain (a) why I am getting it and (b) how I fixed it. The purpose of this series of posts is partly to explain Rust, but partly just to gain data for myself. I may also write posts about errors I’m not getting – basically places where I anticipated an error, and used a pattern to avoid it. I hope that after writing enough of these posts, I or others will be able to synthesize some of these facts to make intermediate Rust material, or perhaps to improve the language itself.

  • Mozilla publishes recommendations on government vulnerability disclosure in Europe
    As we’ve argued on many occasions, effective government vulnerability disclosure (GVD) review processes can greatly enhance cybersecurity for governments, citizens, and companies, and help mitigate risk in an ever-broadening cyber threat landscape. In Europe, the EU is currently discussing a new legislative proposal to enhance cybersecurity across the bloc, the so-called ‘EU Cybersecurity Act’. In that context, we’ve just published our policy recommendations for lawmakers, in which we call on the EU to seize the opportunity to set a global policy norm for government vulnerability disclosure.

  • Supporting Same-Site Cookies in Firefox 60
    Firefox 60 will introduce support for the same-site cookie attribute, which allows developers to gain more control over cookies. Since browsers will include cookies with every request to a website, most sites rely on this mechanism to determine whether users are logged in. Attackers can abuse the fact that cookies are automatically sent with every request to force a user to perform unwanted actions on the site where they are currently logged in. Such attacks, known as cross-site request forgeries (CSRF), allow attackers who control third-party code to perform fraudulent actions on the user’s behalf. Unfortunately current web architecture does not allow web applications to reliably distinguish between actions initiated by the user and those that are initiated by any of the third-party gadgets or scripts that they rely on.
  • Enterprise Policy Support in Firefox
    Last year, Mozilla ran a survey to find out top enterprise requirements for Firefox. Policy management (especially Windows Group Policy) was at the top of that list. For the past few months we’ve been working to build that support into Firefox in the form of a policy engine. The policy engine adds desktop configuration and customization features for enterprise users to Firefox. It works with any tool that wants to set policies including Windows Group Policy.
  • any.js
    Thanks to Ms2ger web-platform-tests is now even more awesome (not in the American sense). To avoid writing HTML boilerplate, web-platform-tests supports .window.js, .worker.js, and .any.js resources, for writing JavaScript that needs to run in a window, dedicated worker, or both at once. I very much recommend using these resource formats as they ease writing and reviewing tests and ensure APIs get tested across globals.

Fedora Workstation 28 Coming Soon

  • Warming up for Fedora Workstation 28
    Been some time now since my last update on what is happening in Fedora Workstation and with current plans to release Fedora Workstation 28 in early May I thought this could be a good time to write something. As usual this is just a small subset of what the team has been doing and I always end up feeling a bit bad for not talking about the avalanche of general fixes and improvements the team adds to each release.
  • Fedora Workstation 28 Is Shaping Up To Be Another Terrific Update
    Fedora Workstation 28 is shaping up to be another compelling update for those that are fans of this bleeding-edge Red Hat sponsored Linux distribution. I've been running Fedora Workstation 28 snapshots on a few laptops and test machines here and am quite happy with how it's shaped up as another Fedora release that delivers not only the latest features, but doing so in a seemingly sane and stable manner: I haven't encountered any problems unlike some of the past notorious Fedora releases from years ago. Overall, I am quite excited for next month's Fedora 28 release and will be upgrading my main production system to it.

Configuring local storage in Linux with Stratis

Configuring local storage is something desktop Linux users do very infrequently—maybe only once, during installation. Linux storage tech moves slowly, and many storage tools used 20 years ago are still used regularly today. But some things have improved since then. Why aren't people taking advantage of these new capabilities? This article is about Stratis, a new project that aims to bring storage advances to all Linux users, from the simple laptop single SSD to a hundred-disk array. Linux has the capabilities, but its lack of an easy-to-use solution has hindered widespread adoption. Stratis's goal is to make Linux's advanced storage features accessible. Read more
