Chromebooks Switching Over To The BFQ I/O Scheduler

On Chromebooks when moving to the latest Chrome OS that switches over to a Linux 4.19 based kernel, BFQ has become the default I/O scheduler. BFQ has been maturing nicely and as of late there's been an uptick in interest around this I/O scheduler with some also calling for it to be used by default in distributions. Google has decided BFQ is attractive enough to enable by default for Chromebooks to provide better responsiveness. Read more

Debian: Salsa, Promoting Debian LTS and Debian Patch Porting System

  • salsa.debian.org: Postmortem of failed Docker registry move

    The Salsa admin team provides the following report about the failed migration of the Docker container registry. The Docker container registry stores Docker images, which are for example used in the Salsa CI toolset. This migration would have moved all data off to Google Cloud Storage (GCS) and would have lowered the used file system space on Debian systems significantly. [...] On 2019-08-06 the migration process was started. The migration itself went fine, although it took a bit longer than anticipated. However, as not all parts of the migration had been properly tested, a test of the garbage collection triggered a bug in the software. On 2019-08-10 the Salsa admins started to see problems with garbage collection. The job running it timed out after one hour. Within this timeframe it not even managed to collect information about all used layers to see what it can cleanup. A source code analysis showed that this design flaw can't be fixed. On 2019-08-13 the change was rolled back to storing data on the file system.

  • Raphaël Hertzog: Promoting Debian LTS with stickers, flyers and a video

    With the agreement of the Debian LTS contributors funded by Freexian, earlier this year I decided to spend some Freexian money on marketing: we sponsored DebConf 19 as a bronze sponsor and we prepared some stickers and flyers to give out during the event. The stickers only promote the Debian LTS project with the semi-official logo we have been using and a link to the wiki page. You can see them on the back of a laptop in the picture below.

    Like each month, here comes a report about the work of paid contributors to Debian LTS.

  • Jaskaran Singh: GSoC Final Report

    The Debian Patch Porting System aims to systematize and partially automate the security patch porting process. In this Google Summer of Code (2019), I wrote a webcrawler to extract security patches for a given security vulnerability identifier. This webcrawler or patch-finder serves as the first step of the Debian Patch Porting System. The Patch-finder should recognize numerous vulnerability identifiers. These identifiers can be security advisories (DSA, GLSA, RHSA), vulnerability identifiers (OVAL, CVE), etc. So far, it can identify CVE, DSA (Debian Security Advisory), GLSA (Gentoo Linux Security Advisory) and RHSA (Red Hat Security Advisory). Each vulnerability identifier has a list of entrypoint URLs associated with it. These URLs are used to initiate the patch finding.

Marek’s Take: Why open source communities are critical to operators

Open source locks down standards in code and makes sure it is interoperable, Rice said. “That’s why it’s symbiotic. Standards are options but they come together because they are built on one another.”

And, similar to standards bodies, where delegates work side-by-side with competitors to develop global specifications, the same occurs in open source groups.
