Linux KPI-Based DRM Modules Now Working On FreeBSD 11

Filed under
Linux
BSD

Thanks to work done by Hans Petter Selasky and others, this drm-next-kmod port is working on FreeBSD 11 stable. What's different with this package from the ports collection versus the ported-from-Linux Direct Rendering Modules found within the FreeBSD 11 kernel is that these DRM modules are using the linuxkpi interface.

FreeBSD Finally Gets Mitigated For Spectre & Meltdown (and Hugs)

  • FreeBSD Finally Gets Mitigated For Spectre & Meltdown

    Landing in FreeBSD today was the mitigation work for the Meltdown and Spectre CPU vulnerabilities.

    It's taken a few more weeks longer than most of the Linux distributions to be re-worked for Spectre/Meltdown mitigation as well as DragonFlyBSD, but with FreeBSD Revision 329462 it appears their initial fixes are in place.

    There is Meltdown mitigation for Intel CPUs via a KPTI implementation similar to Linux, the Kernel Page Table Isolation. There is also a PCID (Process Context Identifier) optimization for Intel Westmere CPUs and newer, just as was also done on Linux.

OPNsense 18.1

BSD
  • OPNsense 18.1 released

    For more than 3 years now, OPNsense is driving innovation through modularising and hardening the open source firewall, with simple and reliable firmware upgrades, multi-language support, HardenedBSD security, fast adoption of upstream software updates as well as clear and stable 2-Clause BSD licensing.

    We humbly present to you the sum of another major iteration of the OPNsense firewall. Over the second half of 2017 well over 500 changes have made it into this release, nicknamed "Groovy Gecko". Most notably, the firewall NAT rules have been reworked to be more flexible and usable via plugins, which is going to pave the way for subsequent API works on the core firewall functionality. For more details please find the attached list of changes below.

  • OPNsense 18.1 BSD Firewall/Network OS Released

    After hitting the RC phase a few weeks ago, OPNsense 18.1 has been officially released as the latest version of this pfSense-forked network/router-oriented BSD operating system.

    OPNsense 18.1 is based on FreeBSD 11.1 while pulling in the HardenedBSD security changes. OPNsense 18.1 reworks its firewall NAT rules, PHP 7.1 and jQuery 3 are powering the web interface, there is now OpenVPN multi-remote support for clients, IPv6 shared forwarding support, improvements for intrusion detection alerts, a rewritten firewall live log, reverse DNS support for insight reporting, and a variety of new plugins.

BSD: LLVM/Clang-Based AOCC and OpenBSD Foundation Fundraising Campaign

  • AMD AOCC Compiler 1.1 Released For Zen CPUs

    AOCC 1.1 is the second public release of the AMD Optimizing C/C++ Compiler designed for Ryzen/Threadripper/EPYC processors.

    Back in May AMD released AOCC 1.0 as their optimized compiler stack for Ryzen CPUs. AOCC is the replacement to the company's older AMD Open64 compiler designed for older CPUs. With Open64 sadly being a relic now of the past, AOCC is based upon LLVM/Clang.

  • Our 2018 Fundraising Campaign

    The OpenBSD Foundation needs your help to achieve our fundraising goal of $300,000 for 2018.

    Reaching this goal will ensure the continued health of the projects we support, will enable us to help them do more, and will avoid the distraction of financial emergencies that could spell the end of the projects.

Are the BSDs dying? Some security researchers think so

Filed under
BSD

Struck by the small number of reported BSD kernel vulnerabilities compared to Linux, von Sprundel sat down last summer and reviewed BSD source code in his spare time. "How come there are only a handful of BSD security kernel bugs advisories released every year?" he wanted to know. Is it because the BSDs are so much more secure? Or is it because no one is looking?

von Sprundel says he easily found around 115 kernel bugs across the three BSDs, including 30 for FreeBSD, 25 for OpenBSD, and 60 for NetBSD. Many of these bugs he called "low-hanging fruit." He promptly reported all the bugs, but six months later, at the time of his talk, many remained unpatched.

"By and large, most security flaws in the Linux kernel don't have a long lifetime. They get found pretty fast," von Sprundel says. "On the BSD side, that isn't always true. I found a bunch of bugs that have been around a very long time." Many of them have been present in code for a decade or more.

Some FreeBSD Users Are Still Running Into Random Lock-Ups With Ryzen

Filed under
BSD

While Linux has been playing happily with Ryzen CPUs as long as you weren't affected by the performance marginality problem where you had to swap out for a newer CPU (and Threadripper and EPYC CPUs have been running splendid in all of my testing with not having any worries), it seems the BSDs (at least FreeBSD) are still having some quirks to address.

This week on the FreeBSD mailing list has been another thread about Ryzen issues on FreeBSD. Some users are still encountering random lockups that do not correspond to any apparent load/activity on the system.

The Top 10 Linux Distros You Never Heard About

Filed under
GNU
Linux
BSD

As I have mentioned in previous articles, the open-source community is littered with many distributions – some of which you might never get to hear about if you’re not connected to an affiliated party or happen to come across a reference ad.

Plus, it’s a new year and we have been dropping Top 10 (and sometimes higher) titles since it began so you shouldn’t be surprised that we are here with another one.

In case you missed it, we recently published an article on The Top 10 Linux Desktop Distros of 2017, and I thought it will be nice if we checked out a couple of distros that might not have made it to the limelight in 2017 but are still significant and will probably be of great use to our readers.
