Very cool! Stefan Sperling (stsp@)'s initial implementation of #OpenBSD WPA3 support is now available testing! 🥳 This project was funded by The NLnet foundation's NGI0 Commons Fund, which supported Stefan's work on a new open source #WPA3 implementation for OpenBSD.

Not great timing, I know, but I'd like to replace my aging/noisy AMD Zen1+ desktop, maybe w/ an Intel mini PC (e.g: N150, 11th Gen i5/i7) for my #OpenBSD testing & hacking, Any help towards this would be greatly appreciated. ☺️ www.paypal.com/donate/?host...

Stefan Sperling (stsp@) shared yet another important milestone on the road to OpenBSD #WPA3 support: The first ever WORKING SAE handshake on #OpenBSD! 😎🐡 bsd.network/@stsp/116930...

Support for the loongson platform has been retired in #OpenBSD -current and has been unhooked from the build. 7.9 is the last release for this platform. marc.info?l=openbsd-cv... marc.info?l=openbsd-cv...

#EuroBSDCon 2026 schedule is up, very much looking forward to Ori Bernstein (ori@)'s talk "GEFS: The File Shredder of the Future"😅 events.eurobsdcon.org/2026/talk/NV... events.eurobsdcon.org/2026/schedule/

if you need me my superpower is they can't get me fired I'm already unemployed. 🖕🤣

Mark Kettenis added support for heartbeat blinking LEDs based on system load averages to OpenBSD/arm64 and OpenBSD/riscv64 boards. 😎 marc.info?l=openbsd-cv... Similar functionality also exists on sparc64 and HP PA-RISC machines. #OpenBSD #blinkenlights

OpenSSH 10.4 has just been released This release includes a number of security and bug fixes, as well as a handful of new features - most notable experimental support for a hybrid post-quantum signature scheme (ML-DSA 44 with Ed25519). www.openssh.org/releasenotes...

Happy 4th of July to all my American pals. 🍕

A few people have asked me recently about how OpenSSH sshd implements privilege separation after the changes of the last couple of years, such as splitting sshd into multiple binaries. I finally got around to writing it up - please take a look if you're curious. github.com/openssh/open...

#OpenBSD #g2k26 hackathon report: Rafael Sadowski (rsadowski@), Netherlands 2026

Fun read. oldvcr.blogspot.com/2026/06/work...

I'm already sensing an uptick in #defcon / #blackhat related posts in my feed lately, so if you're attending either this summer, don't forget the #1 hacker conference rule: "Unattended laptops will be upgraded to OpenBSD -current" Buy my mix tape

Hello shiny new followers! Hello slightly less shiny old followers.

Mark Kettenis has brought over the generic binary codepatching infrastructure to the OpenBSD/arm64 kernel, and is using it to NOP out costly mitigations for microarchitectural vulnerabilities on CPUs that are not vulnerable. (1/2)

Hope my fellow #OpenBSD developers are having an amazing time this week at the #g2k26 #hackathon in Kloosterburen (The Netherlands)! 😎 (g2k26 hackathon artwork by Niki Hettwer)

#OpenBSD -current has cranked the kernel virtual address space (VM_MAX_KERNEL_ADDRESS) on amd64 from 4GB to 512GB (one PML4 entry with 4-level paging). marc.info?l=openbsd-cv... Good news for people with AMD Radeon GPUs with lots of VRAM. 😎

Happy Father's Day to all the fathers out there that don't ghost their children throughout their entire adult life.

I could really use a few extra pizzas this month, friends. 🍕🐡 #HelpSky #MutualAid

Stefan Sperling (stsp@) shared some WPA3 progress on Mastodon today! 😎 "The first ever successful SAE [WPA3-Personal] message exchange between #OpenBSD (iwx driver) and linux hostapd has occurred. There is still some work left do but the hard part is done!"

Hope all my *BSD friends visiting Canada for #BSDCan this week have fun in Ottawa! 😊 ... but not too much fun. 🤨

Years ago, there was a BSD search page at google dot com/bsd (long gone), amusingly, the custom logo is still hosted on Google's servers. www.google.com/sitesearch/b...

FreeBSD 15.1 released! Upgrade to OpenBSD 7.9 today! ☺️

Seems the macOS 27 beta bootpicker issue has been resolved in the Asahi install script, but the beta should still be avoided for now (SMC issues). github.com/AsahiLinux/a... #OpenBSD #NetBSD #FreeBSD

I'll be slacking^Wwatching thfr@ (bsd.network/@thfr) stream @wadjeteyegames.com's Unavowed game on #OpenBSD using IndieRunner/scummvm! #PlayOnBSD

After a flurry of recent commits by Claudio Jeker (claudio@), an important development milestone has been reached, mwx(4), the WIP #OpenBSD driver for Mediatek chips, can now associate and RX/TX with an open WiFi AP! 🎉 "This commit was done over mwx(4) with a MT7921" marc.info?l=openbsd-cv...

I'm noticing a recent uptick in sportsball posts..

I appreciate all the people who continue to support my silly pizza and occasional OpenBSD antics here, even if I'm a bit less active. 🫶

An #OpenBSD story just before summer break from Miod Vallat, lock in, this one is a bit of doozy, "Trojaned OpenSSH" (2002) Certain names have been redacted. 😅

The total smaller donations from the #OpenBSD community to the OpenBSD Foundation has already reached Iridium tier again for 2026 and it's only June! Very cool! 😎 www.openbsdfoundation.org/campaign2026...

Before the inevitable "Apple KILLS unsupported OSes" spin. If Apple wanted to kill Linux (or *BSD), they wouldn't have to subtly break it in a macOS beta. They designed the security model on these machines to allow booting 3rd party OS's. It's not a jailbreak. asahilinux.org/docs/platfor...

Heads up: This very likely also affects booting other non-Linux OS's on Apple silicon, don't upgrade to the macOS 27 beta. #OpenBSD #FreeBSD #NetBSD

PSA for #AsahiLinux users: Do NOT upgrade to macOS 27 Golden Gate! Apple has changed how the boot picker and Startup Disk applications detect valid OS boot volumes. When using either from macOS 27, your Asahi partition will not be visible! We believe this to be a bug, and have filed a report.

#OpenBSD has a new browser in -current ports! #LibreWolf! marc.info?l=openbsd-po... Thanks goes to Leah Rowe (maintainer) for sticking with it and getting the port into shape and ready for import!

Some days I think I should record tech videos/stream, but then I remember I live like a slob and don't own any fake plants. 😔

While I genuinely appreciate any pizza gifts/donations, I'm going to hack on what I want to hack on, not what someone else wants me to hack on. No strings attached, please. 😔

7.8/7.9 errata patches for vmd, xorg, and OpenSMTPD have been released, along with binary syspatches for amd64/i386 and arm64. Reminder: You can subscribe to email notifications of security and reliability fixes via the #OpenBSD announce@ mailing list: lists.openbsd.org/cgi-bin/mj_w...

Domains renewed.

Heads up! The base versions of LLVM/Clang/lld have been updated to 22.1.6 from 19.1.x in #OpenBSD -current. 🐡 marc.info?l=openbsd-cv... marc.info?l=openbsd-cv... marc.info?l=openbsd-cv... UPDATE: robert@'s commit msgs accidentally say 21.1.6, but it's actually 22.1.6. 😎

Good news for Apple T2 Mac owners, @jcs.org has committed a fix to #OpenBSD -current for the T2 NVMe controller found on later Intel machines. 👍 "This gets NVMe working on the 2018 Mac Mini." marc.info?l=openbsd-cv...
