EuroBSDCon 2014 talks and tutorials

OpenBSD adopts SipHash

  • Even more DJB crypto somehow finds its way into OpenBSD’s base system
  • This time it’s SipHash, a family of pseudorandom functions that’s resistant to hash bucket flooding attacks while still providing good performance
  • After an initial import and some clever early usage, a few developers agreed that it would be better to use it in a lot more places
  • It will now be used in the filesystem, and the plan is to utilize it to protect all kernel hash functions
  • Some 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 episode
  • The first maintenance update for the 10.x branch is out, improving upon a lot of things found in 10.0-RELEASE
  • The 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 ZFS
  • Lots of new ARM hardware is supported now, including SMP support for most of them
  • A new kernel selection menu was added to the loader, so you can switch between newer and older kernels at boot time
  • 10.1 is the first to support UEFI booting on amd64, which also has serial console support now
  • Lots of third party software (OpenSSH, OpenSSL, Unbound..) and drivers have gotten updates to newer versions
  • It’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 today
  • Check the detailed release notes for more information on all the changes
  • Also take a look at some of the known problems to see if you’ll be affected by any of them
  • PC-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 Quebec
  • The 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 time
  • It 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 uses
  • There’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 it
  • Very detailed and informative presentation, and the slides can be found here
  • A 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-system’s” 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.”

Interview – Justin Cormack – justin@netbsd.org / @justincormack

NetBSD on Xen, rump kernels, various topics

News Roundup

The FreeBSD foundation’s biggest donation

  • The FreeBSD foundation has a new blog post about the largest donation they’ve ever gotten
  • From the CEO of WhatsApp comes a whopping one million dollars in a single donation
  • It also has some comments from the donor about why they use BSD and why it’s important to give back
  • Because the FreeBSD Foundation is a 501(c)(3) it must show that it has support of the general public, not just a small number of large donors. That is why individual donations are so important
  • Donate even just $5, just to increase the number of names on the donors list
  • Don’t know what to get your favourite FreeBSD developer for Christmas? Donations can be dedicated to others
  • Spread the money around, donate to the foundation of each BSD you use when you can – every little bit helps: OpenBSD, NetBSD and DragonFly
  • You use OpenSSH don’t you? gzip (bsd licensed gzip is from NetBSD)?, newfs_msdos (making FAT(32) file systems for USB devices etc, also from NetBSD)

OpenZFS Dev Summit 2014 videos

BSDTalk 248

  • Our friend Will Backman is still busy getting BSD interviews as well
  • This time he sits down with Matthew Dillon, the lead developer of DragonFly BSD
  • We’ve never had Dillon on the show, so you’ll definitely want to give this one a listen
  • They mainly discuss all the big changes coming in DragonFly’s upcoming 4.0 release

pkgng 1.2 released

  • bapt and bdrewery from the portmgr team released pkgng 1.2 final
  • New features include an improved build system, plugin improvements, new bootstrapping command, SRV mirror improvements, a new \”pkg config\” command, repo improvements, vuXML is now default, new fingerprint features and much more
  • Really simple to upgrade, check our pkgng tutorial if you want some easy instructions
  • It\’s also made its way into Dragonfly
  • See the show notes for the full list of new features and fixes

ChaCha20 and Poly1305 in OpenSSH

  • Damien Miller recently committed support for a new authenticated encryption cipher for OpenSSH, chacha20-poly1305
  • Long blog post explaining what these are and why we need them
  • This cipher combines two primitives: the ChaCha20 cipher and the Poly1305 MAC
  • RC4 is broken, we needed an authenticated encryption mode to complement AES-GCM that doesn\’t show the packet length in cleartext
  • Great explanation of the differences between EtM, MtE and EaM and their advantages
  • \”Both AES-GCM and the EtM MAC modes have a small downside though: because we no longer desire to decrypt the packet as we go, the packet length must be transmitted in plaintext. This unfortunately makes some forms of traffic analysis easier as the attacker can just read the packet lengths directly.\”

Is it time to dump Linux and move to BSD

  • ITworld did an article about switching from Linux to BSD
  • The author\’s interest was sparked from a review he was reading that said \”I feel the BSD communities, especially the FreeBSD-based projects, are where the interesting developments are happening these days. Over in FreeBSD land we have efficient PBI bundles, a mature advanced file system in the form of ZFS, new friendly and powerful system installers, a new package manager (pkgng), a powerful jail manager and there will soon be new virtualization technology coming with the release of FreeBSD 10.0\”
  • The whole article can be summed up with \”yes\” – ok, next story!

OpenZFS devsummit videos

  • Kicking off the ZFS episode, we\’ve got…
  • The OpenZFS developer summit discussion and presentation videos are up
  • People from various operating systems (FreeBSD, Mac OS X, illumos, etc.) were there to discuss ZFS on their platforms and the challenges they faced
  • Question and answer session from representatives of every OS – had a couple FreeBSD guys there including one from the foundation
  • Presentations both about ZFS itself and some hardware-based solutions for implementing ZFS in production
  • TONS of video, about 6 hours\’ worth
  • This leads us into our interview, which is…

Interview – George Wilson – Soft Eng at Delphix – wilzun@gmail.com / @zfsdude

  • KM: Can you tell us a little about yourself how you first got involved with ZFS?
  • AJ: Which features have you worked on in the past?
  • KM: Which platform do you personally use ZFS on, and for what tasks?
  • AJ: So what exactly is the OpenZFS project about?
  • KM: What do you hope the future of OpenZFS will bring?
  • AJ: When are we going to see native encryption?
  • KM: Are there some new features you\’re currently hacking on?
  • AJ: Is there anything specific you\’d like to see added to ZFS in the future?
