[$] How to unbreak LTTng

화, 2020/04/21 - 7:37오전
Back in February, the kernel community discussed the removal of a couple of functions that could be used by loadable modules to gain access to symbols (functions and data structures) that were not meant to be available to them. That change was merged during the 5.7 merge window. This change will break a number of external modules that depended on the removed functions; since many of those modules are proprietary, this fact does not cause a great deal of anguish in the kernel community. But there are a few out-of-tree modules with GPL-compatible licenses that are also affected by this change; one of those is LTTng. Fixing LTTng may not be entirely straightforward.

Python 2.7.18, the end of an era

화, 2020/04/21 - 1:12오전
Python 2.7.18 is out. This is the last release and end of support for Python 2. "Python 2.7 has been under active development since the release of Python 2.6, more than 11 years ago. Over all those years, CPython's core developers and contributors sedulously applied bug fixes to the 2.7 branch, no small task as the Python 2 and 3 branches diverged. There were large changes midway through Python 2.7's life such as PEP 466's feature backports to the ssl module and hash randomization. Traditionally, these features would never have been added to a branch in maintenance mode, but exceptions were made to keep Python 2 users secure. Thank you to CPython's community for such dedication."

Kernel prepatch 5.7-rc2

월, 2020/04/20 - 7:12오전
The 5.7-rc2 kernel prepatch is out for testing. "Everything continues to look fairly normal, with commit counts right in the middle of what you'd expect for rc2. And most of the changes are tiny and don't look scary at all."

Greg Kroah-Hartman has released the 5.6.5, 5.5.18, 5.4.33, and 4.19.116 stable kernels. They contain a seemingly larger-than-usual collection of fixes throughout the kernel tree; users of those series should upgrade.

[$] Debian discusses Discourse

토, 2020/04/18 - 1:35오전
Much of the free software we run every day was developed over email, and the developers of that software, who may have been using email for decades, tend to be somewhat attached to it. The newer generation of developers that came later, though, has proved remarkably resistant to the charms of email-based communication. That has led to an ongoing push to replace email with other forms of communication; often the "other form" of choice is a web-based system called Discourse. Moving to Discourse tends to be controversial; LWN covered related discussions in the Fedora and Python projects in 2018. Now it is Debian's turn to confront this question.

How to livestream a conference in just under a week (FSF)

토, 2020/04/18 - 12:24오전
On the FSF blog, Zoe Kooyman describes how the LibrePlanet 2020 conference was converted to a virtual conference in a week's time—using free software, naturally. "In 2016, we gained some livestreaming experience when we interviewed Edward Snowden live from Moscow. To minimize the risk of failed recordings due to overly complex or error-prone software systems, we made it a priority to achieve a pipeline with low latency, good image quality, and low CPU usage. The application we used then was Jitsi Meet, and the tech info and scripts we used for streaming from 2016 are available for your information and inspiration. Naturally, for this year, with no time for researching other applications, we opted to build on our experience with Jitsi Meet. We hosted our own instance for remote speakers to connect to and enter a video call with the conference organizers. A screen capture of this call was then simultaneously recorded by the FSF tech team, and streamed out to the world via Gstreamer and Icecast."

[$] The integrity policy enforcement security module

금, 2020/04/17 - 6:15오전
There are many ways to try to keep a system secure. One of those, often employed in embedded or other dedicated-purpose systems, is to try to ensure that only code that has been approved (by whoever holds that power over the system in question) can be executed. The secure boot mechanism, which is intended to keep a computer from booting anything but a trusted kernel, is one piece of this puzzle, but its protection only extends through the process of booting the kernel itself. Various mechanisms exist for protecting a system after it boots; a new option for this stage is the Integrity Policy Enforcement (IPE) security module, posted by Deven Bowers.
