If any of my past work on #OpenBSD, or my highlight posts here (or Twitter/Mastodon) has been helpful to you, a small recurring monthly donation would be extremely appreciated. Reposts welcome. ๐๐ก

this is an erogenous zone
I'd like to hear more about your upcoming podcast.
Cool.

A lot of hubbub over a crash, a DoS, not a privesc or RCE.
OpenBSD never claimed to have zero remote crashes. The goal has always been to minimize attack surface and mitigate the impact of attacks.
Errata + binary syspatches have been out for 7.7/7.8 release users for ~3 weeks.
no idea about the original HIMEM.SYS, but mickey@'s himem.sys for OpenBSD/i386 was indeed cursed ๐
brynet.ca/pub/himem.sys (diff backup)
Not a "zero-day" as the quoted post claimed. OpenBSD fixed the SACK issue almost a month ago. It's a crash, not a RCE, either (unlike the FreeBSD issue).
> GTA (grand-theft-autocomplete), "27-year-old bug found in OpenBSD ..."
Fixed by human beings, w/ errata/binary syspatches released to users ~90 minutes after committed to -rHEAD.

Lost another monthly donation.. tthat's okay. ๐
I don't suppose that I have any #openbsd #linux #infosec (or #bitcoin millionaire) friends out there willing to signal boost my pinned profile post, by chance? You'd really be helping me out a bunch! ๐กโค๏ธ
Whoever it is, I'm still going to silently judge them if they're eating the cauliflower wings.
In lieu of kstat(1), kettenis@ tested on:
* Lenovo x13s (Snapdragon 8c): Cortex-A78C -> E + Cortex-X1C -> P
* Rock 5B (Rockchip RK3588): Cortex-A55 -> E + Cortex-A76 -> P
* Apple Mac mini (M2 Pro): Blizzard -> E + Avalanche -> P
* Radxa Orion O6 (Cix CD8180): Cortex-A520 -> L + Cortex-A720 -> P
Mark Kettenis has added arm64 support for the new hw.blockcpu sysctl, classifying CPU types based on device-tree and ACPI CPPC (Collaborative Processor Performance Control) information.

HID support might even be useful, just without all the netbt/AF_BLUETOOTH socket(2) stuff. ๐
#OpenBSD -current has introduced a new hw.blockcpu sysctl to offer more control over which CPU core types (Performance, Efficiency, and SMT) are available to schedule processes on. Modern Intel (and ARM) CPUs additionally have slower LP-E (low-power) core that severely hinder system performance.
openbsd mitigates this by not having a forum
Kirill A. Korinsky (kirill@) has added 160MHz channel width support (5GHz) to #OpenBSD's net80211 wireless stack, with the first driver receiving support being iwx(4) for Intel WiFi 6/6E devices.

In addition to funding #opensource projects you use, if you can, please consider extending support to the individual contributors/developers personally who work on those projects, many are volunteers and even a small monthly contribution could mean the difference. โฅ๏ธ

@jack on Twitter/X: "is the future value of "open source" code anymore? i believe it's shifting to data, provenance, protocols, evals, and weights. in that order."
Or maybe the true "future value" is in the human beings who write, review, and maintain the open source code.
Just a heads up, the unveil of sendmail/cpp "x" is not pointless, and the unveil of / "r" doesn't make them readable. This is a common misunderstanding of unveil(2), which Theo de Raadt clarified here.
David Leadbeater (welcome dgl@! ๐) has shared some information regarding the recent __pledge_open(2) changes in #OpenBSD 7.9-beta, including some good advice for porters.
