OpenBSD developer Vadim Zhukov (zhukov@) has added preliminary OpenBSD support to Open Broadcaster Software (OBS) Studio release 26.1.0 and later. The changes come as part of an ongoing collaboration between the upstream OBS project and OpenBSD developers.

Preliminary OpenBSD support was added in two commits. One introduced sndio(7) support. This adds a sndio plugin which Zhukov advises will provide more reliable, lower latency audio mixing than the ffmpeg plugin for OpenBSD users. The other provides basic support such as help evaluating OpenBSD-specific filesystem paths.

A link to the release was posted on Reddit, with a title claiming full OpenBSD support. Bryan Steele (brynet@) was quick to provide helpful context in a comment:

Note that this is still a WIP and it hasn't been submitted to the ports mailing list or committed to the ports tree, zhuk@ and others have been working with the upstream. As I understand there are issues that still remain, so "full OpenBSD support" is a bit premature.

With the following commit, Marcus Glocker (mglocker@) added an enhanced privacy control for video recording:

Module name:	src
Changes by:	mglocker@cvs.openbsd.org	2020/12/28 11:28:11

Modified files:
	sys/dev        : video.c 
	sys/kern       : kern_sysctl.c 
	sys/sys        : sysctl.h 

Log message:
Analog to the the kern.audio.record sysctl parameter for audio(4)
devices, introduce kern.video.record for video(4) devices.  By default
kern.video.record will be set to zero, blanking all data delivered
by device drivers which attach to video(4).

The idea was initially proposed by
Laurence Tratt <laurie AT tratt DOT net>.

This is analogous to kern.audio.record, which was first seen in OpenBSD 6.4.

Undeadly.org co-editor Peter Hansteen writes in, saying,

On Saturday November 7th I remote participated in OpenFest 2020 with an updated version of the OpenBSD and you talk.

Recordings will be released after the conference, but I was happy enough with my dry run or backup recording that I'm making that available too, along with the slides to follow along. I hope this will be useful in your advocacy or education on OpenBSD and why the project matters.

In case you were wondering, this is an update on a talk we covered previously, with updates to cover the more recent OpenBSD 6.8.

Solène Rapenne (solene@) has written a blog entry on the software system underlying the building of -stable packages:

In this long blog post, I will write about the technical details of the OpenBSD stable packages building infrastructure. I have setup the infrastructure with the help of Theo De Raadt who provides me the hardware in summer 2019, since then, OpenBSD users can upgrade their packages using pkg_add -u for critical updates that has been backported by the contributors. Many thanks to them, without their work there would be no packages to build.

(-stable packages have been the subject of earlier articles.)

Readers are reminded that they can express their gratitude to solene@ and others by donating!

On its 25^th birthday, the OpenBSD project has released OpenBSD 6.8, the 49^th release.

The new release comes with a large number of improvements and debuts a new architecture, OpenBSD/powerpc64, running on the POWER9 family of processors. The full list of changes can be found in the announcement and on the release page. Some highlights:

• As already mentioned, this release debuts the OpenBSD/powerpc64 architecture, supporting the POWER9 [and POWER8] family of processors.
• Numerous kernel improvements such as better time measurements across several architectures, (see eg this article), updated graphics support, and of course numerous improvements in hardware support with updated drivers across several platforms.
• Numerous network stack improvements, including those described by kn@ in his k2k20 hackathon report.
• wg(4), an in-kernel driver for WireGuard VPN [reported previously]
• login_ldap added to base [reported previously]
• FFS2 improvements [some of which were reported earlier]
• LibreSSL 3.2.2 with TLSv1.3 enabled for both client and server, and a new-and-improved X509 certificate chain validator (see beck@'s k2k20 hackathon report).

Those upgrading from 6.7 should consult the Upgrade Guide.

Thanks to the developers for all the good work that went into this excellent new release!

While your install sets download or when your packages update, please take the time to look at and use one or more of the recommended ways to support the project, such as making a donation, buying T-shirts. Corporate entities may prefer sending some money in the direction of the OpenBSD Foundation, which is a Canadian non-profit corporation.

Introduction

Hitherto, releases of the fwobac software (which underlies Undeadly) have been unsigned. This is overdue for change, so for the latest release [version 1.7], we are providing a digital signature. As signing is being performed manually, why not employ an additional [hardware] factor?

signify(1) does not support the use of FIDO authenticators. However, recent versions of OpenSSH do support signing using the [under-appreciated] -Y sign option of ssh-keygen(1), and with the recent addition of FIDO authenticator support to OpenSSH [as reported previously], we have a means (using tools in base OpenBSD) of using a hardware factor when signing files.

Todd Mortimer (mortimer@) has committed RETGUARD (see previous coverage) for the macppc (powerpc) and powerpc64 platforms:

Ingo (schwarze@) writes in about a side project he's been working on to do his own accounting:

Sometimes, it happens to me that i make little progress with the work i planned to do (so let's not talk about the badly needed mandoc release today) and instead end up doing work that wasn't planned at all.

Fresh off the k2k20 hackathon, Rafael Sadowski (rsadowski@) writes in:

Due to the pandemic, this hackathon seemed to be called very spontaneously. Fortunately, the hackathon was over a weekend. This enabled me to attend without missing any professional obligations. On Friday morning, shortly after sunrise, I took the train to Bad Liebenzell. On the train I worked for my employer until I reached Karlsruhe at about 11am. I swapped my MacBook for my OpenBSD ThinkPad T470s.
