[$] 4.15 Merge window part 1

Friday 17th of November 2017 04:07:28 PM
When he released 4.14, Linus Torvalds warned that the 4.15 merge window might be shorter than usual due to the US Thanksgiving holiday. Subsystem maintainers would appear to have heard him; as of this writing, over 8,800 non-merge changesets have been pulled into the mainline since the opening of the 4.15 merge window. Read on for a summary of the most interesting changes found in that first set of patches.

Introducing container-diff, a tool for quickly comparing container images (Google Open Source Blog)

Friday 17th of November 2017 12:03:10 AM
Google has announced that it has released its container-diff tool under the Apache v2 license. "container-diff helps users investigate image changes by computing semantic diffs between images. What this means is that container-diff figures out on a low-level what data changed, and then combines this with an understanding of package manager information to output this information in a format that’s actually readable to users. The tool can find differences in system packages, language-level packages, and files in a container image. Users can specify images in several formats - from local Docker daemon (using the prefix `daemon://` on the image path), a remote registry (using the prefix `remote://`), or a file in the .tar in the format exported by "docker save" command. You can also combine these formats to compute the diff between a local version of an image and a remote version."

[$] SPDX identifiers in the kernel

Thursday 16th of November 2017 05:28:02 PM
Observers of the kernel's commit stream or mailing lists will have seen a certain amount of traffic referring to the addition of SPDX license identifiers to kernel source files. For many, this may be their first encounter with SPDX. But the SPDX effort has been going on for some years; this article describes SPDX, along with why and how the kernel community intends to use it.

NumPy will drop Python 2 support

Wednesday 15th of November 2017 05:48:44 PM
The NumPy project is phasing out support for Python 2. "The Python core team plans to stop supporting Python 2 in 2020. The NumPy project has supported both Python 2 and Python 3 in parallel since 2010, and has found that supporting Python 2 is an increasing burden on our limited resources; thus, we plan to eventually drop Python 2 support as well. Now that we're entering the final years of community-supported Python 2, the NumPy project wants to clarify our plans, with the goal of to helping our downstream ecosystem make plans and accomplish the transition with as little disruption as possible." NumPy releases will fully support both Python 2 and Python 3 until December 31, 2018. New feature releases will support only Python 3 as of January 1, 2019. (Thanks to Nathaniel Smith)

[$] SciPy reaches 1.0

Wednesday 15th of November 2017 05:29:58 PM

After 16 years of evolution, the SciPy project has reached version 1.0. SciPy, a free-software project, has become one of the most popular computational toolkits for scientists from a wide range of disciplines, and is largely responsible for the ascendancy of Python in many areas of scientific research. While the 1.0 release is significant, much of the underlying software has been stable for some time; the "1.0" version number reflects that the project as a whole is on solid footing.

[$] KAISER: hiding the kernel from user space

Wednesday 15th of November 2017 01:16:56 AM
Since the beginning, Linux has mapped the kernel's memory into the address space of every running process. There are solid performance reasons for doing this, and the processor's memory-management unit can ordinarily be trusted to prevent user space from accessing that memory. More recently, though, some more subtle security issues related to this mapping have come to light, leading to the rapid development of a new patch set that ends this longstanding practice for the x86 architecture.

Firefox 57

Tuesday 14th of November 2017 04:36:09 PM
Firefox 57 has been released. From the release notes: "Brace yourself for an all-new Firefox. It’s fast. Really fast. It’s over twice as fast as Firefox from 6 months ago, built on a completely overhauled core engine with brand new technology from our advanced research group, and graced with a clean, modern interface. Today is the first of several releases we’re calling Firefox Quantum, all designed to get to the things you love and the stuff you need faster than ever before. Experience the difference on desktops running Windows, macOS, and Linux; on Android, speed improvements are landing as well, and both Android and iOS have a new look and feel. To learn more about Firefox Quantum, visit the Mozilla Blog."

[$] ROCA: Return Of the Coppersmith Attack

Tuesday 14th of November 2017 04:33:11 PM

On October 30, 2017, a group of Czech researchers from Masaryk University presented the ROCA paper at the ACM CCS Conference, which earned the Real-World Impact Award. We briefly mentioned ROCA when it was first reported but haven't dug into details of the vulnerability yet. Because of its far-ranging impact, it seems important to review the vulnerability in light of the new results published recently.

Fedora 27 released

Tuesday 14th of November 2017 02:15:11 PM
The Fedora 27 release is now available. "The Workstation edition of Fedora 27 features GNOME 3.26. In the new release, both the Display and Network configuration panels have been updated, along with the overall Settings panel appearance improvement. The system search now shows more results at once, including the system actions. GNOME 3.26 also features color emoji support, folder sharing in Boxes, and numerous improvements in the Builder IDE tool."

Attendees have put together reports from all five days (two for Netconf and three for Netdev) that LWN is happy to publish for them.

Red Hat Enterprise Linux for ARM64

Monday 13th of November 2017 06:49:21 PM
Red Hat has announced a version of its RHEL 7.4 distribution for the ARM64 architecture. "Red Hat took a pragmatic approach to Arm servers by helping to drive open standards and develop communities of customers, partners and a broad ecosystem. Our goal was to develop a single operating platform across multiple 64-bit ARMv8-A server-class SoCs from various suppliers while using the same sources to build user functionality and consistent feature set that enables customers to deploy across a range of server implementations while maintaining application compatibility." More information about what works at this point can be found in the release notes.
