Announcing NetBSD Hackathon in Paris - 6 and 7th of November, 2010.

September 29, 2010 posted by Guillaume Lasmayous

On the 6 and 7th November 2010 will be run the first NetBSD Hackathon in Paris, France. The event will be held at ESPCI Paris.

Everybody that has an interest in NetBSD, from developers, documentation writers, translators, to advanced users, are invited to attend.
If you just want to come and discuss NetBSD with some NetBSD enthusiasts, you are also welcome.

The idea is to take this opportunity to meet with the French and French-speaking NetBSD community, for a hacking week-end: contributions to src, pkgsrc, xsrc, wiki, documentation in French on NetBSDfr wiki, submitting or closing PRs, etc.. Let's meet on Saturday, November 6th, starting at 9 am in ESPCI Paris Tech (thanks manu@ for hosting us).

If you wish to join us, please send a mail to guigui _AT_ netbsdfr _DOT_ org (as we need to provide a list of attendees in order to get access to the ESPCI premises).

NB: Accommodation and food will be the responsibility of the attendee. However the organisers are currently looking into a meal at a local restaurant on Saturday night.

Revolutionizing Kernel Development: Testing With Rump

August 19, 2010 posted by Antti Kantee

There are numerous good tools which do an excellent job of testing kernel features and help to catch bugs. The more frequently they are run as part of the regular development cycle, the more bugs they expose before the bugs are shipped to be discovered by end users. However, prior to being able to execute kernel tests configuration is required. Examples of configuration steps include mounting the file system under test, setting up an NFS server, selecting a network interface and configuring an IP address or setting up a test network. This makes taking a kernel test suite into use unnecessarily complicated and reduces the likelihood of all tests being run by any single kernel developer as part of the development process, thereby reducing the number of bugs which are caught early on.

This article explains how rump is the enabling technology for a safe, fast and run-anywhere kernel test suite which requires absolutely no configuration from the person running the tests. We will look at various kernel tests, such as those related to file systems, IP routing and kernel data structures, and point out the advantages of using rump as compared to conventional testing approaches.

Google Summer of Code project Implementing HTTP support for libsa

July 18, 2010 posted by Brett Lymn

Zoltan Arnold NAGY has been busy coding away on his project to add support for booting over HTTP to libsa. Early on in his work he found that the current libsa PXE support used the UDP support functions in the PXE ROM which is unsuitable for HTTP as this requires a TCP transport. Zoltan has written a net_if driver for libsa that uses the PXE UNDI functions to allows both UDP and TCP network packets to be sent. Using the new net_if he was able to boot a kernel using tftp which proved that the basic networking functions were working correctly.

Once the underlying network layer was available Zoltan moved on to the primary aim of the project, booting over HTTP. He has made good progress on this and reports that he can boot a kernel three out of four times via HTTP, clearly one of the goals for the remainder of the Summer of Code is to get this to a 100% hit rate for booting.

There is still a fair bit of work to be done but I believe that Zoltan is on track to providing a useful factility to libsa. Zoltan posted a link to his patches in a posting to the tech-net mailing list

Testing NetBSD: Easy Does It

June 24, 2010 posted by Antti Kantee

It requires only one command to run the NetBSD test suite on a fresh installation or to check if code changes have caused regressions. This article explains why and how, and looks into the ATF and Anita tools which make testing so easy everyone should be doing it.

Solutions Linux 2010 - 16-18th March, Paris Porte de Versailles

April 02, 2010 posted by Guillaume Lasmayous

For the 11th year, was held the "Solutions Linux and Opensource" event in Paris Porte de Versailles, from March 16th to 18th.

NetBSD has been running a booth for the 2nd year in the "Associations' village", where visitors could find most of the active Free and Open Source Software associations: April, {Ubuntu,Mandriva,Fedora}-fr, as well as FreeBSD-fr and BSDFrance, among many others.

4 NetBSD developers were present on the event:

  • Emile "imil" Heitor
  • Antoine "tonio" Reilles
  • Jean-Yves "jym" Migeon
  • Guillaume "gls" Lasmayous
Several other active members of the french NetBSD community were also present to man the booth.

Even though this event is primarily business-oriented, the vast majority of questions were "end-users" oriented questions, the most common one being: how does NetBSD compare to Linux/Ubuntu ? However this year, we had a number of more technical questions, mainly from people willing to run embedded NetBSD.

We distributed something like 150 Jibbed live CDs, 250 NetBSD stickers, and 25 "Powered by NetBSD" case badges.

Next French events where NetBSD will be present:
  • Rencontre Bretonnes du Logiciel Libre, on May, 15-16 in Rennes.
  • Journées Méditérranéennes du Logiciel Libre on November 26-27 in Nice/Sophia-Antipolis.



Kernel modules for macppc and shark

January 19, 2010 posted by Julio Merino

As of past night, the macppc and shark ports have support for the new-style kernel modules. I've added support for these through a workaround in the build system, which makes the compiler generate long jumps for all calls in the code, avoiding unsupported ELF relocation types. This allows us to use the modules even if the kernel-level loader is not able to deal with such relocations. The kernel-level support is now enabled by default in macppc and shark GENERIC kernels.

We'll need to revisit this in the future and implement real support for dealing with those relocation types. Why? The modules built with this flag are slower than they should be... but at least they do work.



Hardware accelerated Xorg on Shark is back

November 25, 2009 posted by Michael Lorenz

Hardware accelerated X for Rev. 4 Sharks using the xf86-video-chips driver has been around for a while but Rev. 5 Sharks were stuck with a dumb framebuffer driver. This has changed, a few days ago I committed an Xorg driver for the IGS CyberPro 2010 graphics controller found in Rev. 5 Sharks.

OpenGrok for NetBSD

November 03, 2009 posted by Zafer Aydoğan

The opengrok code search and cross reference service has been set up and is available at:

It contains the NetBSD sources which are updated every three hours.
This service is running on NetBSD-5 using opengrok with openjdk from pkgsrc.

Happy Grokking :)



BSD Magazine: NetBSD sshfs

In BSD Magazine issue 4/2009 I write about out-of-the-box support for sshfs on NetBSD 5.0. The article goes over the basic principles, use, tuning, and features in store beyond NetBSD 5.0. See the magazine website for purchase/subscription instructions.
