Reyk Floeter (reyk@): From BSDCan to t2k13
Contributed by jj on Thu Jun 13 15:23:03 2013 (GMT)
from the dont-get-laid-get-relayd dept.

I came to Canada to speak about OpenIKED at BSDCan 2013 in Ottawa, moved on with an amazing road trip through Eastern U.S., and finally arrived at the t2k13 OpenBSD Hackathon in Toronto. I usually don't have a fixed agenda for hackathons, so I arrived there, talked with fellow developers and decided about my coding tasks.

Alexander Bluhm (bluhm@) t2k13 report: network stack cleanup, PF, checksums, routing
Contributed by jj on Thu Jun 13 08:26:19 2013 (GMT)
from the it's all a bunch of tubes dept.

The newest entry in our continuing series of t2k13 hackathon reports comes from Alexander Bluhm (bluhm@), who offers some insight into his work in various parts of the network stack:

As a starter, I cleaned up some code in the IPv4 and IPv6 network stack. A hackathon is a great time to work as the other developers are around. You get fast OKs and can ask questions while doing the review. So I also looked into rtadvd, UTF-8 locale support, pf, IPv4 checksum calculation and IPv4 source routing.

Jasper Lievisse Adriaanses (jasper@) t2k13 report
Contributed by jj on Wed Jun 12 08:42:15 2013 (GMT)
from the hunt for red Octeon dept.

Jasper Lievisse Adriaanse (jasper@) writes about his experiences at t2k13:

Unlike previous hackathons I didn't have a clear idea what I wanted to work on, apart from "some ports" and "some octeon" stuff. Which as I came to learn is much better than having a fixed set of tasks...since you'll almost never do just that what you thought you would work on. There's always something more interesting that pops up.

Paul Irofti: t2k13: Hibernating on the Loongson
Contributed by pitrh on Wed Jun 12 08:07:36 2013 (GMT)
from the sleep deep dept.

Further swelling our t2k13 hackathon coverage, Paul Irofti (pirofti@) sent us this report:

I spent most of the hackathon adding hibernate support for the Loongson architecture.

I found the work that mlarkin@ and deraadt@ have done on hibernate to be quite interesting. Unfortunately during their initial work on i386 and amd64 I was focused on different topics and I kind of lost the train on that one.

No matter, I decided to join in on the hibernate effort and Loongson seemed like the perfect architecture for that. I already added suspend support for it a few years ago so hibernation would be the next logical step.

Antoine Jacoutot (ajacoutot@) t2k13 report
Contributed by phessler on Tue Jun 11 11:11:13 2013 (GMT)
from the a twisty maze of dependencies dept.

One of our resident Hobbits, Antoine Jacoutot (ajacoutot@) writes in with his report of the t2k13 Hackathon:

As usual, what I ended up doing during this hackathon was completely different from what I had in mind... which means my TODO list is still not shrinking :-/

Philip Guenther: t2k13: guenther's tale
Contributed by pitrh on Tue Jun 11 08:10:46 2013 (GMT)
from the time and threads unwinding dept.

Here is, as promised, the next installment in our series of t2k13 hackathon reports. This one comes from Philip Guenther (guenther@), who writes:

t2k13 had three phases for me:

1) time_t

As many of know, UNIX represents timestamps as a count of seconds since 1970-01-01 00:00:00 UTC. That's what is stored in the time_t type which is used in many kernel and library APIs, either directly or as part of many structures such as timeval, timespec, and stat.

Currently, OpenBSD defines time_t to be a signed 32bit type. Well, the maximum positive signed 32bit number is only 2147483647, which as a time_t represents 2038-01-19 03:14:07 UTC. That's less than 25 years away, so it's certainly time to get cracking on fixing it.

Landry Breuil: t2k13 hackathon report - firefox, webkit2 & xfce
Contributed by pitrh on Mon Jun 10 18:25:23 2013 (GMT)
from the puffies, lizards, spiders, oh my! dept.

The 8th report in our t2k13 hackathon report series comes from Landry Breuil (landry@), who writes about sundry news in the ports and packages collection:

Prior to t2k13, I had the luck to give a talk at BSDCan in Ottawa about Mozilla on OpenBSD, where I also found henning@, beck@, reyk@ and Peter Hansteen, along with some other friends from the FreeBSD/Dragonfly/NetBSD crowd. This was a really nice event with interesting talks (bhyve anyone ?), and I look forward to come back there next year.

Bob Beck: t2k13 report - buffer cache improvements
Contributed by weerd on Fri Jun 7 13:14:44 2013 (GMT)
from the flipping-and-tossing dept.

Next up in the t2k13 reports is Bob Beck (beck@). Bob has been with the project for a very long time, with lots of deep knowledge on the buffer cache, an area he worked on during this hackahton:

Well, I'm now back from the t2k13 hackathon in Toronto.

Interestingly, the only commit I actually made during the hackathon was to ports - something I rarely do - but I took a few minutes and extended the torture test suite to include a parallel core dumper Theo and I have been using extensively to abuse uvm, the scheduler and the IO midlayer.

Having said that most of the value I got from the hackathon was time to work with krw@ stabilizing the last bits of bugs in the amd64 buffer flipper diff (currently posted to tech@) which I now expect to go in once the tree stabilizes after the hackathon. I also had some really good discussions with tedu@ and guenther@ about several aspects of things, including the possibility of using the midlayer to add support for devices like sd cards that support trim along with an optimization to support tossing buffers we know the filesystem is no longer ineterested in - Something I am looking at as we speak in another window.... So hopefully users can see some payoff from this soon.

joshua stein: t2k13 Hackathon Report - ACPI, CVS, multitouch
Contributed by weerd on Fri Jun 7 13:14:50 2013 (GMT)
from the multi-touch-me dept.

We continue the hackathon reporting with this story from joshua stein (jcs@), who worked on A{HC,CP}I, trackpads, cvs and more during t2k13:

For the Toronto hackathon, my goals were to commit some M's that had been accumulating in my tree for months and to work on some new hardware drivers for better operation of OpenBSD on newer Apple MacBooks.

I sat at a table with Philip Guenther (guenther@), Ted Unangst (tedu@), and Matthew Dempsky (matthew@). Over the course of a week, I overheard more about threads, silly POSIX standards, and Chinese web hackers than I ever wanted to know.
