Users, especially those who use Plugins, Jails, or VMs, are encouraged to update to this release in order to take advantage of the many improvements and bug fixes to those subsystems. Please report any bugs to https://redmine.ixsystems.com/projects/freenas/.

    To update to this release, select the 11.2-STABLE train in System → Update. Should you need to return to the 11.1 series after updating, reboot and select that boot environment from the boot menu.

    The folks at iX Systems have announced their first public beta of FreeNAS 11.2, their downstream of FreeBSD 11.2 focused on supporting network-attached storage (NAS) systems.

What is FreeBSD? Why Should You Choose It Over Linux?

Filed under
Linux
BSD

Not too long ago I wondered if and in what situations FreeBSD could be faster than Linux and we received a good amount of informative feedback. So far, Linux rules the desktop space and FreeBSD rules the server space.

In the meantime, though, what exactly is FreeBSD? And at what times should you choose it over a GNU/Linux installation? Let’s tackle these questions.

FreeBSD is a free and open source derivative of BSD (Berkeley Software Distribution) with a focus on speed, stability, security, and consistency, among other features. It has been developed and maintained by a large community ever since its initial release many years ago on November 1, 1993.

NetBSD 8.0 Release Candidate 2

Filed under
BSD

The NetBSD Project is pleased to announce NetBSD 8.0 RC 2, the second (and hopefully final) release candidate for the upcoming NetBSD 8.0 release.

Unfortunately the first release candidate did not hold up in our extensive testing (also know as eating our own dog food): many NetBSD.org servers/machines were updated to it and worked fine, but the auto build cluster, where we produce our binaries, did not work well. The issue was tracked down to a driver bug (Intel 10 GBit ethernet), only showing up in certain configurations, and it has been fixed now.

Other security events, like the new FPU related exploit on some Intel CPUs, caused further kernel changes, so we are not going to release NetBSD 8.0 directly, but instead provide this new release candidate for additional testing.

NetBSD Audio Improvements Are On The Way For Better Performance & Less Stuttering

Filed under
BSD

Being squared away for the NetBSD 8.1 release are audio improvements within the kernel.

The work being done by Nathanial Sloss eliminates some complexities in the existing code, stopping the copying of stream silence, caching of three blocks of audio, and more.

Rewards of Up to $500,000 Offered for FreeBSD, OpenBSD, NetBSD, Linux Zero-Days

Filed under
Security
BSD

Exploit broker Zerodium is offering rewards of up to $500,000 for zero-days in UNIX-based operating systems like OpenBSD, FreeBSD, NetBSD, but also for Linux distros such as Ubuntu, CentOS, Debian, and Tails.

The offer, first advertised via Twitter earlier this week, is available as part of the company's latest zero-day acquisition drive. Zerodium is known for buying zero-days and selling them to government agencies and law enforcement.

The company runs a regular zero-day acquisition program through its website, but it often holds special drives with more substantial rewards when it needs zero-days of a specific category.

Is FreeBSD faster than Linux?

Filed under
Linux
BSD

FreeBSD is a free and open-source Unix-like OS that powers desktops, servers, and embedded platforms. Unlike Linux, which refers to the kernel combined with GNU to form GNU/Linux, the Operating System, FreeBSD is a complete OS with its own kernel and a focus on stability and speed, among other features.

It is not true that FreeBSD is used on only servers and there are a variety of valid reasons why users argue that it does a better job in general than Linux so you might just give it a try. Both are stable and provide an efficient working environment.

However, the general consensus is that nearly all applications run faster on Linux than FreeBSD, but FreeBSD’s TCP/IP stack has way less latency (faster response time) than Linux. This is reportedly the reason why Netflix streams its shows on FreeBSD and even pay some of its engineers to contribute to its kernel codebase.

  • Workarounds To Get AMD Zen/Ryzen CPUs Running Solid On FreeBSD

    While the Linux support for AMD Ryzen/EPYC processors has been solid on Linux now largely the past number of months with just some exceptions like Raven Ridge display issues, the FreeBSD support has been a bit more choppy.

    The number of AMD Zen + FreeBSD issues has gone down in recent months when using the latest FreeBSD code, but some have still talked of stability issues that can creep up over time.

OpenBSD chief de Raadt says no easy fix for new Intel CPU bug

Filed under
Security
BSD

Recompiling is unlikely to be a catch-all solution for a recently unveiled Intel CPU vulnerability known as TLBleed, the details of which were leaked on Friday, the head of the OpenBSD project Theo de Raadt says.

The details of TLBleed, which gets its name from the fact that the flaw targets the translation lookaside buffer, a CPU cache, were leaked to the British tech site, The Register; the side-channel vulnerability can be theoretically exploited to extract encryption keys and private information from programs.
