  • The mysterious case of the Linux Page Table Isolation patches

    tl;dr: there is presently an embargoed security bug impacting apparently all contemporary CPU architectures that implement virtual memory, requiring hardware changes to fully resolve. Urgent development of a software mitigation is being done in the open and recently landed in the Linux kernel, and a similar mitigation began appearing in NT kernels in November. In the worst case the software fix causes huge slowdowns in typical workloads. There are hints the attack impacts common virtualization environments including Amazon EC2 and Google Compute Engine, and additional hints the exact attack may involve a new variant of Rowhammer.

  • Arcan 0.5.4, Durden 0.4

    From left to right, we have a little Raspberry  running the ‘prio’ WM using the broadcom binary blob drivers (so lacks some of the features needed to run durden), with arcan and terminals eating up all of 20MB of ram. The left Macbook running OSX with Arcan/Durden in fullscreen, retina resolution, of course. The Macbook on the right is running the same system on OpenBSD 6.2. The three-headed monkey behind them is a voidlinux setup with two instances, one on an intel GPU, the other on an AMD GPU. If only the android devices on the wall could be brought in on the fun as well…

  • Arcan 0.5.4 Display Server Released With Durden 0.4 Desktop

    Remember Arcan? The Linux display server built off a game engine. The project is ending 2017 with the release of the Arcan 0.5.4 display server and its associated Durden v0.4 desktop.

    With the Arcan 0.5.4 release, its X.Org-backend has been ported to OpenBSD, its VRbridge tool now has basic OpenHMD support, improvements to its Wayland protocol handling, and a lot more.

Debian Developers: Google Summer of Code, Quick Recap of 2017

  • RHL'18 in Saint-Cergue, Switzerland
    In between eating fondue and skiing, I found time to resurrect some of my previous project ideas for Google Summer of Code. Most of them are not specific to Debian, several of them need co-mentors, please contact me if you are interested.
  • Quick recap of 2017
         After the Stretch release, it was time to attend DebConf’17 in Montreal, Canada. I’ve presented the latest news on the Debian Installer front there as well. This included a quick demo of my little framework which lets me run automatic installation tests. Many attendees mentioned openQA as the current state of the art technology for OS installation testing, and Philip Hands started looking into it. Right now, my little thing is still useful as it is, helping me reproduce regressions quickly, and testing bug fixes… so I haven’t been trying to port that to another tool yet. I also gave another presentation in two different contexts: once at a local FLOSS meeting in Nantes, France and once during the mini-DebConf in Toulouse, France. Nothing related to Debian Installer this time, as the topic was how I helped a company upgrade thousands of machines from Debian 6 to Debian 8 (and to Debian 9 since then). It was nice to have Evolix people around, since we shared our respective experience around automation tools like Ansible and Puppet.
