[20160424] NetBSD and Google's Summer of Code 2016: Projects announced
This year, NetBSD is part of Google's Summer of Code again, and the students that will work on NetBSD projects and what their project proposals this year are have been announced: Have a look at the links to learn more about the students and the projects. To all the students - welcome to NetBSD! :-)

[20160422] Two more NetBSD Security Advisories: compatibility layers, Bozohttpd
Two more security advisories have been released:

[Tags: , , ]


[20160416] NetBSD Security Advisories: ntp, libXfont, calendar
NetBSD has released a number of security advisories:
  • 2016-001: Multiple vulnerabilities in ntp daemon
  • 2016-002: BDF file parsing issues in libXfont
  • 2016-003: Privilege escalation in calendar(1)
See the advisories for more information on NetBSD releases that are and are not affected, the severity of the vulnerability as well as the date by which which NetBSD release branch was fixed.

The advisories also contain an abstract of the problem as well as in-depth technicals with solutions and workarounds. Go and have a look!

[20160213] Article: The Complexity of Doing Things Right in Distributed Board Elections
David Maxwell has volunteered to guide the election process of the NetBSD Foundation's Board of Directors for the upcoming election. In this article on LinkedIn David writes about the challenges of voting in a distributed project, and how they are adressed in the early stages of the voting process: ``A secure voting process shares a lot in common with cryptography. The creators have to understand the inputs, the quality of the randomness supplied, and the transformations applied to the data. The designer also needs to understand the properties which are meant to be guaranteed by the process, such as transparency and individual confirmation of the entire process in this case.''

[20160213] Using GPIO on the Raspberry Pi
Marina Brown asked on port-arm how to get GPIO ports going with NetBSD on the Raspberry Pi, has collected the answers and posted the link to the document to the list.

In short, the key is to enable GPIO ports during boot when the system has not raised the securelevel yet.

[20160213] NetBSD on Google's Compute Engine (Update #1)
Benny Siegert posted to Twitter that he got NetBSD going on Google Compute Engine. Similar to Amazon's AWS, Google Compute Engine, according to their website, ``lets you create and run virtual machines on Google infrastructure. Compute Engine offers scale, performance, and value that allows you to easily launch large compute clusters on Google's infrastructure. There are no upfront investments and you can run thousands of virtual CPUs on a system that has been designed to be fast, and to offer strong consistency of performance.''

For more information, see dmesg output.

Update: Twitter link fixed

[20160131] NetBSD on KVM
KVM is one of many hypervisors that can run NetBSD. In the past the combination did have some issues, but this was fixed after the NetBSD 7 release now, and NetBSD works on KVM. See Emile 'iMil' Heitor's blog posting about more details on the fix and how to start things.

[20151126] Hosted NetBSD (and others) from Serveraptor
Quoting shamelessly from their homepage, ``Serveraptor lets you create VM and install Operating Systems which are hard to find in other providers' offers. You can choose from all active BSD systems, Minix and some niche distributions of GNU/Linux. ''

Packages range from Compsognathus and Deinonychus over Triceratops and Tyrannosaurus up to the Diplodocus, the latter of which comes with 8GB of RAM, 4 CPU cores and 80 GB disk storage. There should be something for everyone!

Check it out: www.serveraptor.com (no dinosaurs were harmed in the making of this blog post!)

[20151126] Wireless, finally - with NetBSD on my Raspberry Pi
I've (literally) coughed up some time to play with my RPI2 the last few days, and I finally got it working with my LogiLink RALINK RA5370 USB-WiFi dongle. Patches are thanks to rjs@, and this gets the machine into a state that I think it's useful to start toying with GPIO and I2C.

For a start, src/share/examples/wpa_supplicant/wpa_supplicand.conf now has an example for a WPA network with no SSID broadcast.

For kicks, here's the full dmesg output:

[20151017] The people behind NetBSD - Seven Interviews for NetBSD 7.0
Surrounding the release of NetBSD 7.0, polish BSD news site Sektor BSD has published a number of interviews with NetBSD developers. Now that the release-dust has settled a bit, here is a list of all the interviews to learn more about the people bringing NetBSD 7.0 to you, in no particular order:

All developers have their unique background, and are working passionately on their own specific areas. As free, non-commercial Open Source project, NetBSD always depends on individuals devoting their time for the cause. It is this devotion and enthusiasm that makes NetBSD - and all of Open Source, really - such a great thing.

If you feel like getting involved, run NetBSD, subscribe to our mailing lists to become part of our community, and have a look at our projects page. Particular areas that are always welcome for contributions are code and documentation, but there is much more. Have a look!
