vmm(4)/vmd(8) support for seabios and linux guests

6 óra 14 perc

Mike Larkin (mlarkin@) writes on tech@:

I just committed the last parts of my working tree to enable both seabios and alpine linux support (using serial console).

This should be enough for people to create images and help find and fix bugs.

See a mailing list archive for the full message.

golang now has native support for OpenBSD's pledge(2)

cs, 2017-03-23 10:37
Google's golang, collaboratively developed by Unix and C pioneers like Ken Thompson, Rob Pike et al has been very BSD friendly (the language itself is BSD licensed) and it just got even friendlier for OpenBSD's pledge mechanism.

To quote the diff:

"unix: add support for OpenBSD pledge

Pledge, the privilege-restricting syscall and mitigation mechanism, was missing from syscall_openbsd.go. As of the latest release, it is officially supported in 'stable'."

Link to the full golang diff here: https://go.googlesource.com/sys/+/8fd966b47dbdd4faa03de0d06e3d733baeb9a1a9%5E%21/

What happened to my vlan?

sze, 2017-02-22 10:54

Hrvoje Popovski kindly wrote in to point out that Martin Pieuchot (mpi@) has written a piece entitled What happened to my vlan?.

The piece begins:

A long term goal of the effort I'm driving to unlock OpenBSD's Network Stack is obviously to increase performances. So I'd understand that you find confusing when some of our changes introduce performance regressions.

Understanding the modernization of the OpenBSD network stack, part 2: A story of if_get(9)

p, 2017-01-13 17:50
Martin Pieuchot has written another article chronicling the modernization of the network stack. Martin writes,

I wrote a second article about the network MP thingy.

The article talks about a new API built on top of a generic solution for a MP problem.

The article, A story of if_get(9), is a followup to the part one article we featured earlier as Understanding the modernization of the OpenBSD network stack, part 1: ART single thread performances.

Read both for a deep dive in the ongoing and exciting work going on right now in the OpenBSD network stack.

Needless to say, editors@ really look forward to seeing more articles in this series.

Get your name in the relayd book

v, 2017-01-08 06:02

Michael W Lucas is offering the chance to get your name in his forthcoming book on relayd and httpd:

There’s a long tradition amongst science fiction writers of selling bit parts in books in exchange for charity donations. It’s called tuckerization.

I see no reason why science fiction writers should have all the fun.

I need a sample user for the forthcoming book on OpenBSD’s httpd and relayd. This user gets referred to in the user authentication sections as well as on having users manage web sites. They will also get randomly called out whenever it makes sense to me.

That sample user could be you.

All it would cost is a donation to the OpenBSD Foundation.

See Michael's blog for details, and donate your way to fame(?) if you can!
