Catanzaro: On WebKit security updates

Tuesday 2nd of February 2016 08:57:33 PM
Michael Catanzaro describes the sad state of WebKit security on Linux distributions and the challenges of security support for such a complex package in general. "We regularly receive bug reports from users with very old versions of WebKit, who trust their distributors to handle security for them and might not even realize they are running ancient, unsafe versions of WebKit. I strongly recommend using a distribution that releases WebKitGTK+ updates shortly after they’re released upstream. That is currently only Arch and Fedora. (You can also safely use WebKitGTK+ in Debian testing — except during its long freeze periods — and Debian unstable, and maybe also in openSUSE Tumbleweed. Just be aware that the stable releases of these distributions are currently not receiving our security updates.)" Lots of information here, worth a read for anybody interested in the topic.

[$] Whole-house audio with free hardware and software

Monday 1st of February 2016 10:55:22 PM
The Black Forest fire destroyed over 500 Colorado houses in June 2013; one of those belonged to longtime Debian developer Bdale Garbee. As he reported during his talk at the 2016 Multimedia and Music miniconf, the house has been redesigned and rebuilt and life is generally better now. Part of the rebuilding process included the incorporation of a whole-house audio system; naturally, Bdale took a unique approach to that task. His talk showed what can be done when one starts from scratch — and doesn't mind designing a circuit board along the way.

Fifteen years of SELinux

Monday 1st of February 2016 07:52:13 PM
This Red Hat blog post celebrates the fifteenth anniversary of the first SELinux release. "With the question of open source security long behind us, we are now focused on providing an even more flexible security model through SELinux. With the rise of composite, distributed applications that can span hundreds of physical and virtual machines as well as disparate cloud instances and Linux container deployments, one-off usage of SELinux is not enough. Instead, we are focused on providing “defense in depth” for modern computing scenarios, effectively building and deploying SELinux policies at each level of the datacenter."

Kernel prepatch 4.5-rc2

Monday 1st of February 2016 02:52:59 AM
The 4.5-rc2 kernel prepatch is out. Linus says things aren't going so slowly anymore: "As late as Friday, I was planning on talking about how nice it is to see this new trend of tiny rc2 releases, because there really hadn't been very many pull requests at all. But it turns out the pull requests were just heavily skewed to the end of the week, and 4.5-rc2 isn't particularly small after all. It pretty much doubled over the weekend." Still, he seems to think that things are working well enough.

NSA Hacker Chief Explains How to Keep Him Out of Your System (Wired)

Thursday 28th of January 2016 08:08:21 PM
Wired reports on a talk at the USENIX Enigma conference by Rob Joyce of the US National Security Agency (NSA). Joyce is the head of the NSA's Tailored Access Operations, which is tasked with breaking into the systems of adversaries and sometimes allies. He spoke about ways to thwart the NSA and other nation-state-level attackers. "'We put the time in …to know [that network] better than the people who designed it and the people who are securing it,' he said. 'You know the technologies you intended to use in that network. We know the technologies that are actually in use in that network. Subtle difference. You'd be surprised about the things that are running on a network vs. the things that you think are supposed to be there.'"

[$] The Linux Foundation changes its bylaws

Wednesday 27th of January 2016 05:44:17 PM
The Linux Foundation's board of directors is not usually a hotbed of controversy; for the most part it does its work in the background, quietly going about the business of directing the non-profit organization. In mid-January that all changed. The bylaws that governed how some at-large board seats were allocated were changed, which caused quite an uproar within the Linux world. While there is speculation about the motive for the change—as well as an official statement of sorts—it certainly seems like the whole thing could have been handled a lot better.

Kernel Space: Linux, Graphics

  • Linux kernel bug delivers corrupt TCP/IP data to Mesos, Kubernetes, Docker containers
    The Linux Kernel has a bug that causes containers that use veth devices for network routing (such as Docker on IPv6, Kubernetes, Google Container Engine, and Mesos) to not check TCP checksums. This results in applications incorrectly receiving corrupt data in a number of situations, such as with bad networking hardware. The bug dates back at least three years and is present in kernels as far back as we’ve tested. Our patch has been reviewed and accepted into the kernel, and is currently being backported to -stable releases back to 3.14 in different distributions (such as Suse, and Canonical). If you use containers in your setup, I recommend you apply this patch or deploy a kernel with this patch when it becomes available. Note: Docker’s default NAT networking is not affected and, in practice, Google Container Engine is likely protected from hardware errors by its virtualized network.
  • Performance problems
    Just over a year ago I implemented an optimization to the SPI core code in Linux that avoids some needless context switches to a worker thread in the main data path that most clients use. This was really nice, it was simple to do but saved a bunch of work for most drivers using SPI and made things noticeably faster. The code got merged in v4.0 and that was that, I kept on kicking a few more ideas for optimizations in this area around but that was that until the past month.
  • Compute Shader Code Begins Landing For Gallium3D
    Samuel Pitoiset began pushing his Gallium3D Mesa state tracker changes this morning for supporting compute shaders via the GL_ARB_compute_shader extension. Before getting too excited, the hardware drivers haven't yet implemented the support. It was back in December that core Mesa received its treatment for compute shader support and came with Intel's i965 driver implementing CS.
  • Libav Finally Lands VDPAU Support For Accelerated HEVC Decoding
    While FFmpeg has offered hardware-accelerated HEVC decoding using NVIDIA's VDPAU API since last summer, this support for the FFmpeg-forked libav landed just today. In June was when FFmpeg added support to its libavcodec for handling HEVC/H.265 video decoding via NVIDIA's Video Decode and Presentation API for Unix interface. Around that same time, developer Philip Langdale who had done the FFmpeg patch, also submitted the patch for Libav for decoding HEVC content through VDPAU where supported.

Unixstickers, Linux goes to Washington, Why Linux?

  • Unixstickers sent me a package!
    There's an old, popular saying, beware geeks bearing gifts. But in this case, I was pleased to see an email in my inbox, from, asking me if I was interested in reviewing their products. I said ye, and a quick few days later, there was a surprise courier-delivered envelope waiting for me in the post. Coincidentally - or not - the whole thing happened close enough to the 2015 end-of-the-year holidays to classify as poetic justice. On a slightly more serious note, Unixstickers is a company shipping T-shirts, hoodies, mugs, posters, pins, and stickers to UNIX and Linux aficionados worldwide. Having been identified one and acquired on the company's PR radar, I am now doing a first-of-a-kind Dedoimedo non-technical technical review of merchandise related to our favorite software. So not sure how it's gonna work out, but let's see.
  • Linux goes to Washington: How the White House/Linux Foundation collaboration will work
    No doubt by now you've heard about the Obama Administration's newly announced Cybersecurity National Action Plan (CNAP). You can read more about it on here and here. But what you may not know is that the White House is actively working with the Linux and open source community for CNAP. In a blog post Jim Zemlin, the executive director of the Linux Foundation said, “In the proposal, the White House announced collaboration with The Linux Foundation’s Core Infrastructure Initiative (CII) to better secure Internet 'utilities' such as open-source software, protocols and standards.”
  • Why Linux?
    Linux may inspire you to think of coders hunched over their desks (that are littered with Mountain Dew cans) while looking at lines of codes, faintly lit by the yellow glow of old CRT monitors. Maybe Linux sounds like some kind of a wild cat and you have never heard the term before. Maybe you have use it every day. It is an operating system loved by a few and misrepresented to many.

RebeccaBlackOS 2016-02-08 Review. Why? Because it’s Friday.

These are the types of problems found in an independent distro build from scratch. I cannot understand how a system built on Debian could be this buggy and apparently have zero VM support which Debian comes with by default. I can take some solace in the fact that it was built by one person and that one person is a Rebecca Black fan but as far as a Linux Distribution is concerned there is not much here. Some could say “Well its not supposed to be taken as a serious Distribution.” True except it is listed and kept up with on DistroWatch therefor it should be held as a system ready distribution especially when it was not released as a beta or an RC. If this distribution is ever going to be considered a real platform it has a long way to go. I give it about as many thumbs down as the Rebecca Black Friday video. Read more
