OpenBSD Foundation 2014/2015 News & Fundraising
Contributed by tbert on Thu Feb 26 08:51:13 2015 (GMT)
from the donate-now-operators-are-standing-by dept.

Ken Westerback (krw@) wrote in on behalf of the OpenBSD Foundation to let us know what happened last year, and what's in store for us now:

2014 was the most successful year to date for the OpenBSD Foundation. Both in the amount of money we raised and in the support we provided for the OpenBSD and related projects. We are extremely grateful for the support shown by our contributers large and small.

A detailed summary of the Foundation's activities in 2014 can be seen at

s2k15 Hackathon Report: krw@ on improvements in dhclient(8), fdisk(8) and more
Contributed by pitrh on Sat Feb 21 22:22:26 2015 (GMT)
from the do dropbears dream of IP addresses dept.

The second s2k15 hackathon reports comes from Ken Westerback (krw@), who writes:

I arrived in Brisbane with Theo in tow and was quickly whisked away by dlg@ to the lovely surroundings of St. Leo's college. The hackroom was across the street and very nice once you got past the giant turkey nest being contructed by a turkey on the sidewalk. Australian birds are weird. The net was especially good. Obviously somebody competent was running it and using a particularly good firewall.

s2k15 Hackathon Report: mpi@ on network stack SMP
Contributed by tbert on Wed Feb 18 08:20:58 2015 (GMT)
from the stacked-in-our-favor dept.

Martin Pieuchot (mpi@) writes in with his report from the s2k15 hackathon:

s2k15 was definitely a hackathon to get things started and for me, the 's' was clearly for SMP. I arrived a bit earlier to be able to finally meet and discuss with David (dlg@), our host, in order to define a strategy to continue moving some bits and pieces of the network stack out of the big lock.

And that's what we did. So we had a look at the glue between the network drivers and the stack and found a way to improve the integration of pseudo drivers in the Ethernet layer. The goal of this refactoring is to avoid recursion and decouple code paths in order to make it easier to turn every pseudo driver MP-safe. That's why I rapidly commited a new interface and then started to convert various drivers.

As usual I committed some bug fixes and other small cleanups in the nework stack and I also took advantage of the fact that Miod (miod@) was sitting next to me, to bother him with some powerpc related questions. We ended up fixing some small bugs for G5 machines. As a result they can now use radeondrm(4) and correctly see all their available memory.

I really enjoyed this shiny week of hacking, thank you very much David for hosting us here and thanks to Theo and the OpenBSD foundation for taking care of my flight and accomodation!

Thanks to Martin for being the first with his post-hackathon write-up!

OpenBSD booth at SCALE 13x
Contributed by tj on Fri Feb 13 02:12:16 2015 (GMT)
from the does-it-scale dept.

Seth writes in to announce the OpenBSD booth at this year's SCALE 13x conference:

The OpenBSD vendor booth rides again this February at Scale 13x. As usual, we'll be peddling OpenBSD merchandise including the much sought after 5.6 CD sets, t-shirts, books, coffee mugs, posters and stickers.

Stop by to shoot the bull, stuff the donation jar, or just straighten out that keel with a shot of 'Puffy-go-go-juice' fresh from our on-site espresso machine. (Sadly, our drone shipment of Puffy-Bolivian-marching-powder is not going to make it this year)

If you can help staff the booth for at minimum 2-3 hours on both Saturday and Sunday, there's a free conference pass waiting on arrival with your name on it. Developers preferred, but anyone with a modicum of social skills is welcome to volunteer. Email Scale13xOpenBSD@hush.ai for more info.


It's being held on February 19th-22nd at the Hilton Los Angeles Airport in Los Angeles, California.

OpenBSD Just Works
Contributed by jj on Thu Feb 12 13:44:38 2015 (GMT)
from the match-on-ix-rdr-to-henning dept.

After what appears to have been a very successful s2k15 hackathon, two significant thank you themed posts have appeared on OpenBSD mailing lists. The first came on misc@ from longtime user and supporter Diana Eichert, with the subject a thankyou to OpenBSD. Diana writes,

I don't post much any more, my OpenBSD systems "just work".

Just wanted to post a thank you to OpenBSD because it does
"just work".

You can check the entire message and followup thread here.

The second came from Henning Brauer (henning@), writing to tech@, with the subject A thanks to the donors, and a small request. Henning writes,

The OpenBSD foundation has just acquired 4 Dell r210s for my OpenBSD
development setup to replace their aging predecessors from 2007.

I would like to take the opportunity to thank everybody who has donated
to the foundation, you made this possible.

And here's a message to potential donors - you can help complete the setup for optimal development conditions:

To complete the setup, I need at least 2 single and one dual port
10GBaseT ix(4) cards. There is one previously donated on in Australia
that I could use, unfortunately we cannot quite figure out right
now whether it is single or dual - depending on that, I'll need 2
single or 1 single and 1 dual port one on top.

The machines come without the rackmount rails, having them would make
it considerably easier for me - for regular 4-post racks.

Henning also notes that for most efficient use of everybody's time, it would be best if the equipment 'just shows up'. You can read the rest of the message here.

If you can help make this happen, please dive in!

For other equipment requests, make sure to check the Hardware Wanted page, or go to the Donations page.

Jazz concert with OpenBSD synths
Contributed by weerd on Wed Feb 11 13:33:46 2015 (GMT)
from the audio0 at hexagone0 dept.

Everybody's favourite audio hacker Alexandre Ratchov (ratchov@) is inviting you to a concert in Grenoble (France). Read on to find out how this relates to OpenBSD:

Announcing a jazz concert here might sound off-topic, but for this one all synthesizers will run on a OpenBSD box. Unfortunately there are no sample recordings available on the web, only this site (in French).

For non-French speakers, the concert takes place at "the Hexagone" in the Grenoble area, Feb 27, 2015. You're welcome.

The music is experimental jazz using micro-tonal instruments, played by great jazz musicians: virtuoso flutist Magic Malik, Maxime Zampieri on the drums and Jean-Luc Lehr on the bass. We use acoustic instruments (fretless bass, drums) and synthesizers (flute-like synths, pads, and percussions). All synths and corresponding effect processors run on a OpenBSD/amd64 box.

There're few input midi(4) devices: a keyboard, a flute-like wind controller, a kit of drum pads, and control surface (bunch of knobs). They send short messages (aka midi events) whenever a key is pressed on the keyboard, the breath pressure changes on the wind controller, or a pad is hit with the stick. The synthesizer is a program (not published yet) that listens on a sndio(7) midithru port, calculates the wave corresponding to input midi events in real-time then sends the result for audio playback to a envy(4) based card. Then, the resulting analog signal is mixed with other analog sources (bass and microphones) and amplified. Everything is configured to have few milliseconds of latency between the moment a midi message arrives and the corresponding signal hits the amplifier.

The music is based on a theory developed by Frederic Faure which is too long to explain here, but it brings a unique sound by carefully choosing note pitches. So we use an additional program to calculate the pitch of each note submitted to the synth and to visualize various aspects of the theory to assist musicians, it also runs on the same box.

There will be a masterclass on this music presented by Malik, Frederic and me on Feb. 25, 2015. We'll discuss practical and theoretical aspects of this music, and if there's interest internals of the synths and the setup.

Maybe see you at the masterclass and/or for a beer after the concert.

So, if you happen to be in the neighbourhood, make sure to stop by. Thanks to Alexandre for his story!

s2k15: Authenticated TLS 'constraints' in ntpd(8)
Contributed by tbert on Tue Feb 10 10:34:10 2015 (GMT)
from the stuck-with-the-MitM-with-you dept.

Reyk Flöter (reyk@) wrote in to tech@, talking about some work he'd done at s2k15:

Hi!

Theo, Henning, and me developed an idea to utilize TLS in some way for authenticated time in ntpd(8). We are not intending to use it as a direct time source, but as a "constraint" to verify the NTP responses. I came up with an implementation that has been designed to be an optional, non-intrusive feature that is now part of OpenBSD -current.
