Stable kernels 4.16.17 and 4.14.51 have been released with lots of fixes throughout the tree. Users should upgrade.

[$] Mentoring and diversity for Python

Wednesday 20th of June 2018 09:38:38 PM

A two-part session at the 2018 Python Language Summit tackled the core developer diversity problem from two different angles. Victor Stinner outlined some work he has been doing to mentor new developers on their path toward joining the core development ranks; he has also been trying to document that path. Mariatta Wijaya gave a very personal talk that described the diversity problem while also providing some concrete action items that the project and individuals could take to help make Python more welcoming to minorities.

[$] Getting along in the Python community

Wednesday 20th of June 2018 07:04:32 PM

In a session with a title that used a common misquote of Rodney King ("can't we all just get along?"), several Python developers wanted to discuss an incident that had recently occurred on the python-dev mailing list. A rude posting to the list led to a thread that got somewhat out of control. Some short tempers among the members of the Python developer community likely escalated things unnecessarily. The incident in question was brought up as something of an object lesson; people should take some time to simmer down before firing off that quick, but perhaps needlessly confrontational, reply.

[$] PEP 572 and decision-making in Python

Wednesday 20th of June 2018 04:41:42 PM

The "PEP 572 mess" was the topic of a 2018 Python Language Summit session led by benevolent dictator for life (BDFL) Guido van Rossum. PEP 572 seeks to add assignment expressions (or "inline assignments") to the language, but it has seen a prolonged discussion over multiple huge threads on the python-dev mailing list—even after multiple rounds on python-ideas. Those threads were often contentious and were clearly voluminous to the point where many probably just tuned them out. At the summit, Van Rossum gave an overview of the feature proposal, which he seems inclined toward accepting, but he also wanted to discuss how to avoid this kind of thread explosion in the future.

Welcome to Fedora CoreOS

Wednesday 20th of June 2018 04:29:20 PM
Matthew Miller looks at how Red Hat's acquisition of CoreOS will affect the Fedora project. "This isn’t the place for technical details — see “what next?” at the bottom of this message for more. I expect that over the next year or so, Fedora Atomic Host will be replaced by a new thing combining the best from Container Linux and Project Atomic. This new thing will be “Fedora CoreOS” and serve as the upstream to Red Hat CoreOS."

[$] TCP small queues and WiFi aggregation — a war story

Monday 18th of June 2018 11:28:40 PM

This article describes our findings that connected TCP small queues (TSQ) with the behavior of advanced WiFi protocols and, in the process, solved a throughput regression. The resulting patch is already in the mainline tree, so before continuing, please make sure your kernel is updated. Beyond the fix, it is delightful to travel through history to see how we discovered the problem, how it was tackled, and how it was patched.

Subscribers can read on for the full story by guest authors Carlo Grazia and Natale Patriciello.

[$] 4.18 Merge window, part 2

Sunday 17th of June 2018 08:23:07 PM
By the time that Linus Torvalds released 4.18-rc1 and closed the merge window for this development cycle, 11,594 non-merge changesets had found their way into the mainline kernel repository. Nearly 4,500 of those were pulled after last week's summary was written. Thus, in terms of commit traffic, 4.18 looks to be quite similar to its predecessors. As usual, the entry of significant new features has slowed toward the end of the merge window, but there are still some important changes on the list.

A set of weekend stable kernel updates

The stable update machine continues to crank out releases: 4.17.2, 4.16.16, 4.14.50, 4.9.109, and 4.4.138 are all available with another set of important fixes.

Kernel prepatch 4.18-rc1

Sunday 17th of June 2018 02:14:04 AM
The first 4.18 prepatch is out, and the merge window has closed for this development cycle. "You may think it's still Saturday for me, and that I should give you one more day of merge window to send in some last-minute pull requests, but I know better. I'm in Japan, and it's Sunday here."

[$] Toward a fully reproducible Debian

Friday 15th of June 2018 02:55:52 PM
It's been a little over one year since we last covered Debian's reproducible builds project. The effort has not stopped in the interim; progress continues to be made, the message has sharpened up, and word is spreading. Chris Lamb, speaking about this at FLOSS UK in a talk called "You may think you're not a target: a tale of three developers", hinted that the end may be starting to come into sight.

Cook: security things in Linux v4.17

Friday 15th of June 2018 11:29:57 AM
Kees Cook describes the security-oriented changes included in the 4.17 kernel release. "It was possible that old memory contents would live in a new process’s kernel stack. While normally not visible, “uninitialized” memory read flaws or read overflows could expose these contents (especially stuff “deeper” in the stack that may never get overwritten for the life of the process). To avoid this, I made sure that new stacks were always zeroed. Oddly, this “priming” of the cache appeared to actually improve performance, though it was mostly in the noise."

Backdoored images downloaded 5 million times finally removed from Docker Hub (ars technica)

Friday 15th of June 2018 11:26:12 AM
Ars technica has the story of a set of Docker images containing cryptocurrency miners that persisted on Docker Hub for the better part of a year — after being discovered. "Neither the Docker Hub account nor the malicious images it submitted were taken down. Over the coming months, the account went on to submit 14 more malicious images. The submissions were publicly called out two more times, once in January by security firm Sysdig and again in May by security company Fortinet. Eight days after last month's report, Docker Hub finally removed the images."
