g2k19 hackathon report from Claudio Jeker

Contributed by Paul 'WEiRD' de Weerd on from the route me up before you go-go dept.

With the latest hackathon finished, the subsequent BSDCan completed and its attendees having returned home, Claudio Jeker (claudio@) writes in with the first report from g2k19:

Travelling to the hackathon was a bit of an adventure this year. The software troubles with the 737 MAX caused frequent scheduling changes. At Montreal airport I ran into tb@ and naddy@ but all of us were on different airplanes to Ottawa. When I finally arrived a different crew of people were waiting for me and my luggage. It is pretty clear that this is a general hackathon if you run into developers everywhere along the way. The last todo item after a long travel day was beer and food at the local pub where all the others were.

docbook2mdoc-1.0.0 released

Contributed by Ingo Schwarze on from the DocBook-considered-woeful dept.

After doing active development on it for about a month, i just released version 1.0.0 of the DocBook to mdoc converter, docbook2mdoc(1). The OpenBSD port was updated, too. In a nutshell, docbook2mdoc was brought from experimental status to an early release that can be considered mostly usable for production, though no doubt there are still many rough edges. That's why i called it 1.0.0 and not 1.1.1.

t2k19 Hackathon Report: Putting the hack(6) in hackathon, and other stories

Contributed by Anthony J. Bentley on from the hack the hack(6) dept.

Fresh from the t2k19 hackathon comes a report from Anthony J. Bentley (bentley@), who writes:

Seeing an Asia hackathon coming up was pretty exciting; I’d never been there before. I spent a month or so preparing by getting through the more mundane things in my backlog, mostly new ports and updates. That left my time in Taipei open to focus on fixing some bugs and broken things.

a2k19 hackathon report from Ken Westerback (krw@)

Contributed by Paul 'WEiRD' de Weerd on from the shire lease dept.

Ken Westerback (krw@) writes in with his report from a2k19, the hackathon in New Zealand:

Due to an earlier (pre-737Max) airplane problem on the flight back from n2k18 in Usti nad Labem, a loosely worded compensation coupon and the cooperation of beck@ in exploiting said wording, I was able to fly Business Class over the Pacific and thus arrived well rested in BNE. Could have been even more rested if I hadn't had to rouse myself to raise a(nother) glass of champagne as we crossed the date line and it became someone's birthday. First world problems.

The alert reader will have noted that BNE is not where a2k19 was. But beck@ and I had decided to personally drag various Australians onto the flight to Wellington the next day.

OpenBSD 6.5

0022019-05-16 RELIABILITY LibreSSL servers did not provide an SRTP profile, so DTLS negotiation failed.
0012019-05-03 RELIABILITY If a userland program sets the IPv6 checksum offset on a raw socket, an incoming packet could crash the kernel. ospf6d is such a program.
