OpenBSD developers from around the world have just gathered in Nantes, France for the p2k16 hackathon. This event is technically a ports hackathon, but many non-porters have showed up too, which means you can expect a variety of different improvements.As an early example, ajacoutot@ has just set sysmerge to run automatically during the upgrade process.Head over to the hackathons page to see the artwork, and stay tuned to Undeadly for some post-hackathon reports.

This year's AsiaBSDCon has come to an end, with a number of OpenBSD-related talks being presented. Two developers were also invited to the smaller "bhyvecon" event to discuss vmm(4) and future plans.Antoine Jacoutot (ajacoutot@) - OpenBSD rc.d(8) (slides | paper)Henning Brauer (henning@) - Running an ISP on OpenBSD (slides)Mike Belopuhov (mikeb@) - Implementation of Xen PVHVM drivers in OpenBSD (slides | paper)Mike Belopuhov (mikeb@) - OpenBSD project status update (slides)Mike Larkin (mlarkin@) - OpenBSD vmm Update (slides)Reyk Floeter (reyk@) - OpenBSD vmd Update (slides)Videos will likely be uploaded later on. And finally, you can usually find most of the OpenBSD-related presentations at openbsd.org/papers. Future conferences can also be seen at openbsd.org/events.html.

The 5.9 festivities are starting earlier than usual this time around, with the songs being available before the OS! Accompanying the release media are the following tracks:"Doctor W^X" (mp3 | ogg)"Systemagic (Anniversary Edition)" (mp3 | ogg | lyrics)Seasoned OpenBSD users may notice that the second song is a reprisal of "Systemagic" from way back in the 3.1 release days.Enjoy the tunes! If you're an audio snob like a couple of us here at Undeadly, the uncompressed lossless versions can be found on the 5.9 CD set as always.
on (#15MMG)
As noted by Bernard Spil, the OpenSSL bugs disclosed on 2016-03-01 have very little impact on LibreSSL, especially on OpenBSD. However, we will briefly mention the two high-profile issues:LibreSSL (on any platform) is not affected by DROWN. Support for SSLv2 was flensed out quite a while ago.Cachebleed is local-only, and requires a lot effort to get. This is thought to be very difficult to exploit on OpenBSD due to many of the normal mitigations on an OpenBSD system. Other systems without such mitigations may not be so lucky.
