Kristaps Dzonsons, of mandoc and acme-client (and more) fame, has written a detailed article entitled "why pledge(2) …or, how I learned to love web application sandboxing".
The tl;dr section starts:For practical web applications, pledge(2) presents the best compromise of development simplicity and security coverage. This alone gives BCHS applications even more of a boost beyond the many other advantages of programming on OpenBSD.
The article discusses the advantages of pledge(2) over other sandboxing systems.
It gives an overview (with relevant links) of recent significant changes in -current.
Update: there is now a second part.
Today's big news comes from the OpenBSD Foundation, via director Ken Westerback. The official word from the foundation is:
The OpenBSD Foundation is excited to announce that it has received its largest ever donation. Smartisan (http://www.smartisan.com) has become our first Iridium level donor with a donation of CDN$280,000.00.
Smartisan has donated tickets sales from its new product launch events to the open source community since 2014. In 2016 alone, over 10,000 developers and tech-enthusiasts attended its events. This year Smartisan chose to donate the proceeds to the OpenBSD Foundation.
We thank Smartisan for its very generous support! This donation will no doubt fund many exciting projects in the next few years.
Here at Undeadly we join the Foundation in thanking the good people at Smartisan for their generous contribution.
And if you, dear reader want to make a similar contribution (all sizes acceptable), please head on over to the Foundation's Donations page.
The first report out of the just completed l2k16 (LibreSSL focused) hackathon comes from Ingo Schwarze, who writes:
Hackathons are great for starting or finishing tasks. This time, for me, finishing it was. Read more...
The next b2k16 hackathon report comes from Daniel Jakots, who writes:
This was my second hackathon (after p2k16). I was looking forward to it as I had a really great time in Nantes. Read more...
New contributor doctrit writes,
An interesting news article title caught my attention and I was pleasantly surprised to find OpenBSD having a prominent place within the article's content. 8^)
We (editors@) of course agree with the article author that our favorite operating system is worth supporting for all the goodness the project consistently produces.
The first report from the b2k16 hackathon comes from Antoine Jacoutot, who writes:
I was so happy to go back to Budapest for a hackathon. I've been there more times than I can count and it's an awesome city made even more awesome thanks to our host robert@ !
I arrived late the eve of the event along with other flying frogs (espie@, landry@, danj@). We were immediately brought to a Pub to drink an unreasonnable amount of Dreher... fuel up for next day! Read more...
Your next b2k16 report comes form Jeremy Evans, who writes:
I started off b2k16 by channeling tedu@, and removing a lot of ports, including lang/ruby/2.0, lang/io, convertors/ruby-json, databases/dbic++, databases/ruby-swift, databases/ruby-jdbc-*, x11/ruby-profiligacy, and mail/ruby-mailfactory. Read more...
Our next b2k16 report comes from Landry Breuil, who writes:
6 years after my last visit to Budapest.. it's been a while, but the basics of a port hackathon there didn't change:
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: email@example.com 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 in the series of g2k16 hackathon reports is this one from Florian Obser, who writes:
One of the first things to do when attending a hackathon is travel
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...
