  • 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…

Red Hat changes its open-source licensing rules

From outside programming circles, software licensing may not seem important. In open-source, though, licensing is all important. So, when leading Linux company Red Hat announces that -- from here on out -- all new Red Hat-initiated open-source projects that use the GNU General Public License(GPLv2) or GNU Lesser General Public License (LGPL)v2.1 licenses will be expected to supplement the license with GPL version 3 (GPLv3)'s cure commitment language, it's a big deal.
