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

MeetBSD 2014 is approaching

  • The MeetBSD conference is coming up, and will be held on November 1st and 2nd in San Jose, California
  • MeetBSD has an “unconference” format, which means there will be both planned talks and community events
  • All the extra details will be on their site soon
  • It also has hotels and various other bits of useful information – hopefully with more info on the talks to come
  • Of course, EuroBSDCon is coming up before then

First experiences with OpenBSD

  • A new blog post that leads off with “tired of the sluggishness of Windows on my laptop and interested in experimenting with a Unix-like that I haven’t tried before”
  • The author read the famous “BSD for Linux users” series (that most of us have surely seen) and decided to give BSD a try
  • He details his different OS and distro history, concluding with how he “eventually became annoyed at the poor quality of Linux userland software”
  • From there, it talks about how he used the OpenBSD USB image and got a fully-working system
  • He especially liked the simplicity of OpenBSD’s “hostname.if” system for network configuration
  • Finally, he gets Xorg working and imports all his usual configuration files – seems to be a happy new user!

NetBSD rump kernels on bare metal (and Kansai OSC report)

  • When you’re developing a new OS or a very specialized custom solution, working drivers become one of the hardest things to get right
  • However, NetBSD’s rump kernels – a very unique concept – make this process a lot easier
  • This blog post talks about the process of starting with just a rump kernel and expanding into an internet-ready system in just a week
  • Also have a look back at episode 8 for our interview about rump kernels and what exactly they do
  • While on the topic of NetBSD, there were also a couple of very detailed reports (with lots of pictures!) of the various NetBSD-themed booths at the 2014 Kansai Open Source Conference that we wanted to highlight

OpenSSL and LibreSSL updates

  • OpenSSL pushed out a few new versions, fixing multiple vulnerabilities (nine to be precise!)
  • Security concerns include leaking memory, possible denial of service, crashing clients, memory exhaustion, TLS downgrades and more
  • LibreSSL released a new version to address most of the vulnerabilities, but wasn’t affected by some of them
  • Whichever version of whatever SSL you use, make sure it’s patched for these issues
  • DragonFly and OpenBSD are patched as of the time of this recording but, even after a week, FreeBSD (outside of -CURRENT) and NetBSD are not

Interview – Robert Watson – rwatson@freebsd.org

FreeBSD architecture, security research techniques, exploit mitigation

Protecting traffic with a BSD-based VPN

News Roundup

A FreeBSD-based CGit server

  • If you use git (like a certain host of this show) then you’ve probably considered setting up your own server
  • This article takes you through the process of setting up a jailed git server, complete with a fancy web frontend
  • It even shows you how to set up multiple repos with key-based user separation and other cool things
  • The author of the post is also a listener of the show, thanks for sending it in!

Backup devices for small businesses

  • In this article, different methods of data storage and backup are compared
  • After weighing the various options, the author comes to an obvious conclusion: FreeNAS is the answer
  • He praises FreeNAS and the FreeNAS Mini for their tight integration, rock solid FreeBSD base and the great ZFS featureset that it offers
  • It also goes over some of the hardware specifics in the FreeNAS Mini

A new Xenocara interview

  • As a follow up to last week’s OpenSMTPD interview, this Russian blog interviews Matthieu Herrb about Xenocara
  • If you’re not familiar with Xenocara, it’s OpenBSD’s version of Xorg with some custom patches
  • In this interview, he discusses how large and complex the upstream X11 development is, how different components are worked on by different people, how they test code (including a new framework) and security auditing
  • Matthieu is both a developer of upstream Xorg and an OpenBSD developer, so it’s natural for him to do a lot of the maintainership work there

Building a high performance FreeBSD samba server

  • If you’ve got to PXE boot several hundred Windows boxes to upgrade from XP to 7, what’s the best solution?
  • FreeBSD, ZFS and Samba obviously!
  • The master image and related files clock in at over 20GB, and will be accessed at the same time by all of those clients
  • This article documents that process, highlighting some specific configuration tweaks to maximize performance (including NIC bonding)
  • It doesn’t even require the newest or best hardware with the right changes, pretty cool

Feedback/Questions

  • All the tutorials are posted in their entirety at bsdnow.tv
  • We want to give a special thanks to our viewer Adam (aka bsdx) for writing most of today’s OpenVPN tutorial
  • Send questions, comments, show ideas/topics, or stories you want mentioned on the show to feedback@bsdnow.tv
  • Watch live Wednesdays at 2:00PM Eastern (18:00 UTC)
