from the puffy-is-the-captain-of-the-wpa2-enterprise dept.

After seeing discussions on misc@ about where wpa_supplicant would and would not work, Mark Kettenis (kettenis@) decided to take a look at wpa2-enterprise mode for wifi.

This is what he wrote:

Binary patches with BinpatchNG

For many server administrators it may not be desirable to keep a full src tree around to update a system when an errata is published. While this may still be something that could work out just fine on large/fast servers, it's a dreadful task to do this on embedded systems or servers with little diskspace (like CF storage) or limited CPU power (Soekris, Alix, etc).

Debugging the OpenBSD kernel via QEMU
Contributed by pitrh on Thu Jan 10 20:02:02 2013 (GMT)
from the now-the-heisenbug-is-gone-again dept.

Mark Shroyer writes in about how he used QEMU to track down an OpenBSD kernel bug:

Recently I had to track down a minor bug in the OpenBSD kernel. I tapped QEMU and GDB as debugging tools for the task, running on Ubuntu 12.04 as the host OS. This combination worked extremely well, so for the record here’s how I set it all up.

OpenBSD comes equipped with two kernel debugging mechanisms: ddb and kgdb. ddb(4) is an in-kernel debugger, enabled by default in the GENERIC kernel, and can be invoked either explicitly from the console or automatically in the event of a panic. It is analogous to the Linux debugger kdb in that it can be used to set breakpoints and examine the stack or register state, but (like kdb) it is not a source-level debugger.

Sun4v logical domain support coming up.
Contributed by jj on Mon Dec 17 10:58:55 2012 (GMT)
from the yo-dawg-I-heard-you-like-logical-domains dept.

So this stuff is in a usable state now. Below are some instructions on how to use things, and I encourage people with access to suitable hardware to play with it. If you do, you probably should be very current and rebuild your kernel and ldomctl(8) from absolutely -current sources before doing so.

Have fun!

hackathon report covering g2k12 and c2k12 by schwarze@
Contributed by phessler on Thu Nov 22 10:06:18 2012 (GMT)
from the may-the-schwarze-be-with-you dept.

OpenBSD developer Ingo Schwarze (schwarze@) writes in to tell us about the work he has done at two recent hackathons, g2k12 in Budapest Hungary during July, and c2k12 in Coimbra Portugal in November.

The mdoc(7) language can now easily be used to document portable software

Whenever possible, people want to write documentation using the modern, nice, structured BSD mdoc(7) language and not using the dated, ugly, low-level UNIX man(7) language. However, some archaic operating systems like Solaris still do not ship with an mdoc(7) formatter - a fact that is easy to understand when you consider that mdoc(7) was only invented quite recently: It first appeared in 4.4BSD, released in June 1993,
which is less than twenty years ago.
