[$] Adopting DNSSEC

sze, 2016-12-14 21:21
The Domain Name System (DNS) is an amazing technological achievement, but it suffers from a historical excess of trust, which makes it possible for people who rely on it to be lied to. The DNS Security Extensions (formally DNSSEC-bis, more usually just DNSSEC) are a mechanism for including robust trust information within the DNS. Here we discuss briefly what DNSSEC does, how it does it, and how (and whether) you can use it to secure your domains.

Krita 3.1 released

sze, 2016-12-14 18:29
Version 3.1 of the Krita image editor is available. "Krita 3.1 is the result of half a year of intense work and contains many new features, performance improvements and bug fixes. It’s now possible to use render animations (using ffmpeg) to gif or various video formats. You can use a curve editor to animate properties. Soft-proofing was added for seeing how your artwork will look in print. A new color picker that allows selecting wide-gamut colors. There is also a new brush engine that paints fast on large canvases, a stop-based gradient editor." See the release notes for more information.

[$] AMD's Display Core difficulties

k, 2016-12-13 20:26
Back in 2007, the announcement that AMD intended to reverse its longstanding position and create an upstream driver for its graphics processors was joyfully received by Linux users worldwide. As 2017 approaches, an attempt by AMD to merge a driver for an upcoming graphics chip has been rejected by the kernel's graphics subsystem maintainer — a decision that engendered rather less joy. A look at this discussion reveals a pattern seen many times before; the positions and decisions taken can seem arbitrary to the wider world but they are not without their reasons and will, hopefully, lead to a better kernel in the long run.

The 4.9 kernel has been released

v, 2016-12-11 21:55
Linus has released the 4.9 kernel, as expected. Some of the headline features in 4.9 include improved security with virtually mapped kernel stacks, the memory-protection keys system calls, the BBR congestion-control algorithm, support for the Greybus bus architecture, shared extents in the XFS filesystem (which will be used to support lightweight copy operations among other things), and much more. The code name has also been changed to "Roaring Lionus". In the end, 16,216 non-merge changesets were pulled for the 4.9 release, making this development cycle the busiest ever by far.

Stable kernels 4.8.13 and 4.4.37

cs, 2016-12-08 21:36
Greg Kroah-Hartman has announced the release of the 4.8.13 and 4.4.37 stable kernels. As usual, there are fixes throughout the tree and users of those kernel series should upgrade.

Note that the fix for the kernel code execution vulnerability using AF_PACKET sockets (also known as CVE-2016-8655) has not made it into these stable kernels. Those running systemd may want to check Lennart Poettering's blog post on how to mitigate the problem for services started by systemd.

Remembering a friend: Matthew Williams (Fedora Community Blog)

cs, 2016-12-08 19:15
Over at the Fedora Community Blog, Brian Proffitt writes about Fedora member Matthew Williams who passed away recently from cancer. "Matthew’s passion to constantly improve the software and hardware with which he worked created a tireless advocate for the Fedora Project, and his presence was felt at conferences across the nation: SCaLE, Ohio LinuxFest, and the former Indiana LinuxFest, an Indianapolis-based event that he helped found. Matthew also devoted time to interviewing and archiving notable figures in the free and open source software communities to learn what drove people to work on their projects. He was also very driven to share what he knew, launching the Open FOSS training site in 2015 to help new Linux users with getting involved with any Linux distribution. While he was active in the Fedora community, Matthew was also very involved with Ubuntu as well."
