sze, 2017-02-22 09:54

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.

I knew that as soon as I stepped out of the airplane, I would be going to melt. In preparation for my impeding death I had spent the week before on debugging and bringing up the OpenBSD/arm64 port in QEMU.

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

p, 2017-01-13 16:50
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 05:02

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!

Kristaps Dzonsons on pledge(2)

szo, 2016-11-26 04:28

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.
