The OpenBSD project has announced OpenBSD 7.6, its 57th release.

As the next release is slowly cooking, I'd like to mention an artist that I love: @pmjv, or prahou. He's been dedicated to submitting awesome artwork about his universe, here at /c/unix_surrealism, which features many openbsd related comics (puffy being an important protagonist).

I was thus wondering how an artist could pretend at submitting an artwork for the next release ? Is it a shortlist ? Do you simply upload some on the mail list ?

Upcoming EuroBSDCon OpenBSD talk Confidential Computing with OpenBSD by Hans-Jörg Höxer

Confidential computing is a family of techniques to enhance security
and confidentiality for data in use. One technical approach is strong
isolation for virtual machines.

AMDs Secure Encrypted Virtualization (SEV) offers several feature sets
for isolation of guest virtual machines from an non-trusted host hypervisor
and operating system. These feature sets include memory encryption,
encryption of guest state including CPU registers and an attestation
framework.

In this talk we will explore some of the AMD SEV feature sets. We will
describe how to use them to run OpenBSD as both

  • a confidential guest VM and
  • a host hypervisor providing a confidential execution environment.

Topics covered are CPU feature detection, low level kernel initialization,
memory management, virtio(4) device drivers and the virtual machine
daemon vmd(8).

Tickets are still available and this talk will be streamed and recorded for later release.

Utils:

ssh

  • obvious

mg

  • debloated emacs
    • even smaller than nvi/nex!

tmux

  • a lot of people don't realize this is an OpenBSD project
  • session retention

doas

  • configuring sudo feels horrible after configuring doas
  • invaluable in ports

pf

  • ironic that this is most popular outside of OpenBSD (PFSense)

ifconfig

  • command line interface translates directly to configuration files

login.conf/login

  • anything on PenguinOS seems insane by comparison
    • especially oom killer

sndio

  • actually works
    • hopefully this gets popular outside of OpenBSD ;) ;) ;)

vmm/vmd

  • still in its early stages, but I love it

got (technically not an OpenBSD project, but adjacent)

  • debloated git
  • partial git compatibility

Library Functions/Syscalls:

pledge & unveil

  • interesting new approach to jails
  • set and forget, no interaction needed on the user's end
    • with exceptions like chromium & firefox

strtonum

  • far nicer than strto* functions in stdlib

malloc

  • now with use after free and leak detection! who needs valgrind?

The download page leads to install75.img, but the front page still says 7.4.

For anyone wanting to have a nice little cli tool to search the OpenBSD packages repository. Also, there are emojis and much more.

Running a slightly modified version of Lemmy based on 0.18.5. Needed to upgrade a few of the dependencies. The worst was a segfault from the Rust crate jsonwebtoken!

Just spreading love for sysupgrade(8). I had a private server running 7.2 dutyfully serving a PHP software for a local organisation for the past 4 years.

Our provider suffered an outage which brought the server down for a few hours. When it got back up, I decided to use this outage to upgrade it to 7.4.

Two sysupgrade and one pkg_add -u later, the server is up and running again, without further intervention needed.

I did it all from my phone, in a train with a a laggy connection.

Thanks OpenBSD for caring this much about your users ! 🐡♥️

I am a bit surprised no one posted this here yet, but OpenBSD 7.4 was released:

How long does it usually take for you to unhibernate after a ZZZ?

I timed my laptop where it stops at the "unhibernating @ block xxxxxx length xxxMB", and these are my times:

length 65MB: 1m 47s
length 285MB: 3m 29s

Are these normal times?

Setting vm.swapencrypt.enable=0 makes no difference, and according to dmesg "acpi0: sleep states S0 S3 S4 S5".

Hello, I've tried to find someone else using OpenBSD in various places for a while now, but with no success, so I'm hoping someone will read this.

I'm wondering what your output is from file(1) on a file you know has text encoded as UTF-8.

On my system (7.3-stable) the output is "Non-ISO extended-ASCII text", and I'm trying to figure out if this is how it should be, or if I did something wrong setting up the system.

So, if you have a computer with OpenBSD and a minute to spare, could you try running file(1) on a UTF-8 file and see if it identifies it as UTF-8 or "Non-ISO extended-ASCII text"?

Thanks in advance

Considering that OpenBSD's umb(4) and umsm(4) drivers support cards like the Quectel EC25, which comes in a USB variant, I was wondering if it was (at least in theory) possible to make calls using OpenBSD. I know you can get to the internet and send SMS with the smstools port, but what about calling ?
