Five OpenBSD 6.0 CD-ROM copies were signed by 40 developers during the g2k16 Hackathon in Cambridge, UK. These copies are being auctioned sequentially on ebay.
All proceeds will be donated to the OpenBSD Foundation to support and further the development of free software based on the OpenBSD operating system. Read more...
With a small commit, OpenBSD now has a hypervisor and virtualization in-tree. This has been a lot of hard work by Mike Larkin, Reyk Flöter, and many others. VMM requires certain hardware features (Intel Nehalem or later, and virtualization enabled in the BIOS) in order to provide VM services, and currently only supports OpenBSD guests. CVSROOT: /cvs Module name: src Changes by: firstname.lastname@example.org 2016/10/12 02:30:26 Modified files: sys/arch/amd64/conf: GENERIC Log message: enable vmm This has been enabled in snapshots for a week, so your favourite mirror is already ready for you to upgrade. Of course, please report any bugs you run into. This work was partially sponsored by The OpenBSD Foundation, and if you like it, please donate or bid on the signed cd set.
Alexander Bluhm (bluhm@) contributed our next report (which even includes a picture):
Big plans what to do at a hackathon don't work. There is always something unexpected that requires your attention. So I was expecting the unexpected. The TCP send performance has dropped to a very low throughput in some environments. It was pretty clear that it was related with claudio@'s change to speed up TCP by using large mbufs instead of chaining small ones. Mbufs are used inside the kernel to hold network data. Using a lot of them requires many allocations and frees. This can be avoided by using larger mbufs. But why did it get slower? Together with mikeb@ we found out that it was related to the mbuf space limit in the socket buffer. One large mbuf filled the send buffer, so no new mbufs could be inserted until TCP received the acknowledgements for everything. So the sliding window algorithm with mbufs cycling through the socket buffer did not work anymore. After identifying the problem, the fix was easy, just increase the default socket buffer mbuf size limit.Read more...
The g2k16 hackathon must have been a really great one, because here is yet another report, this time from Patrick Wildt, who writes:
I knew that if I had any plans for the hackathon, they would have been thrown out of the window as soon as I arrived there. That was a good plan actually, since exactly that happened. Read more...
The g2k16 hackathon reports keep coming, and we love it! In this fresh report, Martin Pieuchot writes,
Since some years now, I cannot attend a hackathon without having to deal with a USB problem. It's generally a bug that one of the hackers in the room can expose with his hardware. But in Cambridge it was different! Read more...
doas, so its clearly time to write a book. Or maybe a pamphlet.
Matthieu Herrb supplied our next g2k16 report:
I arrived in Cambridge on Tuesday afternoon, after a nice 9h train trip from Toulouse through Paris and the tunnel. I started the hackathon by upgrading a number of packages in Xenocara. The most noteworthy being the XCB (X protocol C-language Bindings) suite updated to the most recent 1.12 version.Read more...
Vincent Gross supplied the next hackathon report:
Although I did attend two hackathons previously, g2k16 at Cambridge was my first general hackathon. I had three targets on my list for this week : iked(8), armv7 and sys/netinet.Read more...
Here's yet another g2k16 hackathon report, this one from Antoine Jacoutot, who writes:
This was my first time in Cambridge and I must say I really enjoyed the place. It's a gorgeous town and avsm@ and Gemma's organization of the hackathon was just perfect. So first of all, thank you very much to them and to the OpenBSD Foundation. Read more...

Next up with a g2k16 Hackathon report is Jasper Lievisse Adriaanse:
Shortly before the hackathon I contacted mpi@ to check up on the status of his Dynamic Profiling (read DTrace) work. This eventually led me to my goal for this hackathon of making a start integrating CTF into our kernel.Read more...
Next up in our series of g2k16 hackathon reports is Christian Weisgerber, who writes:
Another hackathon, another devel/gettext update. This proved to be disappointingly routine and after some other, equally uneventful port updates, I turned my attention to the kernel. Read more...
Our next g2k16 report comes from Brent Cook (bcook@), who writes:
One of the delicate parts of attending an OpenBSD gathering is explaining to immigration officials how you're going to be hacking on security code with people you met on the internet for a week. This is usually a ticket to a second-level security screening, or at least a raised eyebrow.Read more...

This was my second trip to Cambridge, after a whirlwind tour during a EuroBSDCon past. Very happy to return. There's some really old stuff here! Read more...

Next up in our series of g2k16 hackathon reports is this one from Martin Natano:
I arrived at the g2k16 hackathon with the expectation of working on fusefs and indeed on the first day I've committed a diff to clean up the attribute handling in the kernel and libfuse. Next on my list was a bug that manifested itself by fuse mount points becoming unusable after heavy usage of another mount point. Doh! I came up with a diff to fix it. (Reviews welcome!) That fixed, I joined a group of hackers for beer and proper burgers.Read more...
Next in the g2k16 series is the Otto Moerbeek's report. Otto writes,
It has been a while since I was at a hackathon, due to various reasons the last hackathon I attended was in 2008 where I did commit my implementation of malloc. During the years, various improvements to my malloc were done, both by others and myself. Read more...
