    vmm enabled

    sze, 2016-10-12 10:57
    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: 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.

    g2k16 Hackathon Report: Alexander Bluhm on mbufs and more

    szo, 2016-09-17 14:18

    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.

    g2k16 Hackathon Report: Patrick Wildt on arm, LLVM and other progress

    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...

    Ted Unangst on "doas mastery"

    k, 2016-09-13 12:14

    Ted Unangst (tedu@) has written an item regarding doas:

    It’s been a year since the introduction of doas, so it’s clearly time to write a book. Or maybe a pamphlet.

    See his flak entry for the full story (and bear in mind he's referring to -current at the time of writing).

    g2k16 Hackathon Report: Matthieu Herrb on xenodm

    v, 2016-09-11 14:58

    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.

    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[6].

    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...

    One of the first things to do when attending a hackathon is travel planning.

    For me this started a few months back when I got annoyed that getting there would waste a whole day. And I live somewhat close by! Shall I go by train? But how do I figure this out? I could fly, but to where, and then what, need to figure out train options... 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.

    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.

    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.
