  • Here Is A Linux 4.5-rc2 Kernel To Play With The New AMDGPU Functionality

    With a report that Linux 4.5-rc2 manages to improve the AMD R9 Fury (Fiji) performance, I spun up a Linux 4.5-rc2 kernel this morning for easing those wanting to test the AMDGPU driver atop Ubuntu.

    While the Ubuntu Mainline Kernel PPA ships with the AMDGPU DRM driver enabled, it doesn't yet enable the new PowerPlay Kconfig option for getting faster performance on hardware like Fiji, Tonga, etc. Their kernel also doesn't ship with the experimental CIK GPU support enabled. Thus I spun a 4.5-rc2 kernel this morning that enables these extra AMDGPU tunables.

  • AMDGPU Driver Said To Be Much Faster With Linux 4.5-rc2 Kernel

    With Linux 4.5-rc2 that was released last night, the new AMDGPU DRM driver is supposedly much faster compared to last week's 4.5-rc1 kernel.

    A Phoronix reader commented, "I read through the changelog and saw that there were several amdgpu patches. I just built this RC, rebooted, and ran some 3d benchmarks an the result is: a) double or quadruple the framerates that I got with RC1, and Cool no more overheating. I have the same model R9 Fury that Michael excluded from the last round of benchmarks due to performance/stability problems."

  • The Linux Foundation Announces Session Lineup for ApacheCon(TM) Europe
  • OpenShift Commons Gathering event preview
    We're just two months out from the OpenShift Commons Gathering coming up on November 7, 2016 in Seattle, Washington, co-located with KubeCon and CloudNativeCon. OpenShift Origin is a distribution of Kubernetes optimized for continuous application development and multi-tenant deployment. Origin adds developer and operations-centric tools on top of Kubernetes to enable rapid application development, easy deployment and scaling, and long-term lifecycle maintenance for small and large teams. And we're excited to say, the 1.3 GA release of OpenShift Origin, which includes Kubernetes 1.3, is out the door! Hear more about the release from Lead Architect for OpenShift Origin, Clayton Coleman.

Security News

  • Report: Linux security must be upgraded to protect future tech
    The summit was used to expose a number of flaws in Linux's design that make it increasingly unsuitable to power modern devices. Linux is the operating system that runs most of the modern world. It is behind everything from web servers and supercomputers to mobile phones. Increasingly, it's also being used to run connected Internet of Things (IoT) devices, including products like cars and intelligent robots.
  • security things in Linux v4.6
    Hector Marco-Gisbert removed a long-standing limitation to mmap ASLR on 32-bit x86, where setting an unlimited stack (e.g. “ulimit -s unlimited“) would turn off mmap ASLR (which provided a way to bypass ASLR when executing setuid processes). Given that ASLR entropy can now be controlled directly (see the v4.5 post), and that the cases where this created an actual problem are very rare, means that if a system sees collisions between unlimited stack and mmap ASLR, they can just adjust the 32-bit ASLR entropy instead.
