Several companies clarify GPL enforcement policies

h, 2017-11-27 16:24
Here is a press release from Red Hat on GPL enforcement: "To provide greater predictability to users of open source software, Red Hat, Facebook, Google and IBM today each committed to extending the GPLv3 approach for license compliance errors to the software code that each licenses under GPLv2 and LGPLv2.1 and v2." This is, in effect, a reiteration of the approach to enforcement recently adopted by many kernel developers, but it extends to all GPLv2-licensed software contributed by those companies.

Kernel prepatch 4.15-rc1

h, 2017-11-27 02:24
The 4.15-rc1 kernel prepatch is out. "So it's been the usual two weeks of merge window, and rc1 is out. And that normal time length is about the only thing usual about this merge window. Because of the indiscriminate mass slaughter of turkeys in the US last week, lots of people - including me - were on vacation. That meant that I had asked for people to try to make the merge window front-heavy, but it also meant that then during the second week I was rather more strict than usual in what I pulled."

Stable kernel updates

p, 2017-11-24 17:12
Greg Kroah-Hartman has released stable kernels 4.14.2, 4.13.16, 4.9.65, 4.4.101, 4.4.102, and 3.18.84. This is the last 4.13.y kernel and users should upgrade to 4.14 now. For the two 4.4 updates Greg says: "[4.4.102] is a bugfix for an issue if PAGE_POISONING is enabled in the kernel configuration. If you do not run your kernel with that option, no need to upgrade, just stick with 4.4.101."

7 tools for analyzing performance in Linux with bcc/BPF (opensource.com)

sze, 2017-11-22 17:37
Brendan Gregg introduces a set of BPF-based tracing tools on opensource.com. "Traditional analysis of filesystem performance focuses on block I/O statistics—what you commonly see printed by the iostat(1) tool and plotted by many performance-monitoring GUIs. Those statistics show how the disks are performing, but not really the filesystem. Often you care more about the filesystem's performance than the disks, since it's the filesystem that applications make requests to and wait for. And the performance of filesystems can be quite different from that of disks! Filesystems may serve reads entirely from memory cache and also populate that cache via a read-ahead algorithm and for write-back caching. xfsslower shows filesystem performance—what the applications directly experience."

[$] Replacing x86 firmware with Linux and Go

h, 2017-11-20 20:07

The Intel Management Engine (ME), which is a separate processor and operating system running outside of user control on most x86 systems, has long been of concern to users who are security and privacy conscious. Google and others have been working on ways to eliminate as much of that functionality as possible (while still being able to boot and run the system). Ronald Minnich from Google came to Prague to talk about those efforts at the 2017 Embedded Linux Conference Europe.

[$] 4.15 Merge window part 1

p, 2017-11-17 17:07
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)

p, 2017-11-17 01:03
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

cs, 2017-11-16 18:28
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

sze, 2017-11-15 18:48
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

sze, 2017-11-15 18:29

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.
