Understanding the modernization of the OpenBSD network stack, part 2: A story of if_get(9)
Contributed by pitrh on Fri Jan 13 15:50:03 2017 (GMT)
from the puffy the interface juggler dept.

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.

Contributed by pitrh on Mon Jan 9 13:33:21 2017 (GMT)
from the Puffy off the wire dept.

OpenBSD as WiFi access points look set to be making a comeback in the near future.

With this diff https://marc.info/?l=openbsd-tech&m=148396652007923&w=2, Stefan Sperling added 802.11n hostap mode, with full support initially for the Atheros chips supported by the athn(4) driver.

This diff adds 11n support to the athn(4) driver.
Requires -current net80211 code from today.

Tested in hostap mode and client mode with:

athn0 at pci1 dev 0 function 0 "Atheros AR9281" rev 0x01: apic 2 int 16
athn0: AR9280 rev 2 (2T2R), ROM rev 22, adddress xx:xx:xx:xx:xx:xx

Get your name in the relayd book
Contributed by rueda on Sun Jan 8 04:02:42 2017 (GMT)
from the bit-part-for-sale dept.

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!

Peter Hansteen on OpenBSD and you
Contributed by weerd on Tue Dec 27 15:42:29 2016 (GMT)
from the pitrh-promotes-puffy dept.

Undeadly editor Peter Hansteen (pitrh) recently spoke to the Bergen (BSD and) Linux User Group (BLUG) on the subject "OpenBSD and you", and has shared the slides from the talk.

These make a great resource for preaching to the as-yet-unconverted.

Kristaps Dzonsons on pledge(2)
Contributed by rueda on Sat Nov 26 03:28:17 2016 (GMT)
from the the joy of pledge(2) dept.

Kristaps Dzonsons, of mandoc and acme-client (and more) fame, has written a detailed article entitled "why pledge(2) …or, how I learned to love web application sandboxing".

The tl;dr section starts:

For practical web applications, pledge(2) presents the best compromise of development simplicity and security coverage. This alone gives BCHS applications even more of a boost beyond the many other advantages of programming on OpenBSD.

The article discusses the advantages of pledge(2) over other sandboxing systems.
