This time on the show, we'll be talking with Justin Cormack about NetBSD rump kernels. We'll learn how to run them on other operating systems, what's planned for the future and a lot more. As always, answers to viewer-submitted questions and all the news for the week, on BSD Now - the place to B.. SD.

OpenBSD adopts SipHash
Even more DJB crypto somehow finds its way into OpenBSD's base systemThis time it's SipHash, a family of pseudorandom functions that's resistant to hash bucket flooding attacks while still providing good performanceAfter an initial import and some clever early usage, a few developers agreed that it would be better to use it in a lot more placesIt will now be used in the filesystem, and the plan is to utilize it to protect all kernel hash functionsSome other places that Bernstein's work can be found in OpenBSD include the ChaCha20-Poly1305 authenticated stream cipher and Curve25519 KEX used in SSH, ChaCha20 used in the RNG, and Ed25519 keys used in signify and SSH***
FreeBSD 10.1-RELEASE
FreeBSD's release engineering team likes to troll us by uploading new versions just a few hours after we finish recording an episodeThe first maintenance update for the 10.x branch is out, improving upon a lot of things found in 10.0-RELEASEThe vt driver was merged from -CURRENT and can now be enabled with a loader.conf switch (and can even be used on a PlayStation 3)Bhyve has gotten quite a lot of fixes and improvements from its initial debut in 10.0, including boot support for ZFSLots of new ARM hardware is supported now, including SMP support for most of themA new kernel selection menu was added to the loader, so you can switch between newer and older kernels at boot time10.1 is the first to support UEFI booting on amd64, which also has serial console support nowLots of third party software (OpenSSH, OpenSSL, Unbound..) and drivers have gotten updates to newer versionsIt's a worthy update from 10.0, or a good time to try the 10.x branch if you were avoiding the first .0 release, so grab an ISO or upgrade todayCheck the detailed release notes for more information on all the changesAlso take a look at some of the known problems to see if you'll be affected by any of themPC-BSD was also updated accordingly with some of their own unique features and changes***
arc4random - Randomization for All Occasions
Theo de Raadt gave an updated version of his EuroBSDCon presentation at Hackfest 2014 in QuebecThe presentation is mainly about OpenBSD's arc4random function, and outlines the overall poor state of randomization in the 90s and how it has evolved in OpenBSD over timeIt begins with some interesting history on OpenBSD and how it became a security-focused OS - in 1996, their syslogd got broken into and "suddenly we became interested in security"The talk also touches on how low-level changes can shake up the software ecosystem and third party packages that everyone usesThere's some funny history on the name of the function (being called arc4random despite not using RC4 anymore) and an overall status update on various platforms' usage of itVery detailed and informative presentation, and the slides can be found hereA great quote from the beginning: "We consider ourselves a community of (probably rather strange) people who work on software specifically for the purpose of trying to make it better. We take a 'whole-systems' approach: trying to change everything in the ecosystem that's under our control, trying to see if we can make it better. We gain a lot of strength by being able to throw backwards compatibility out the window. So that means that we're able to do research and the minute that we decide that something isn't right, we'll design an alternative for it and push it in. And if it ends up breaking everybody's machines from the previous stage to the next stage, that's fine because we'll end up in a happier place."***

News Roundup
The FreeBSD foundation's biggest donation
The FreeBSD foundation has a new blog post about the largest donation they've ever gottenFrom the CEO of WhatsApp comes a whopping one million dollars in a single donationIt also has some comments from the donor about why they use BSD and why it's important to give backBe sure to donate to the foundation of whatever BSD you use when you can - every little bit helps, especially for OpenBSD, NetBSD and DragonFly who don't have huge companies supporting them regularly like FreeBSD does***
