On this week’s mini-episode, we’ll be talking with Baptiste Daroussin about packaging the FreeBSD base system with pkgng. Is this the best way going forward, or are we getting dangerously close to being Linux-like? We’ll find out, and also get to a couple of your emails while we’re at it, on BSD Now – the place to B.. SD.

Xen dom0 in FreeBSD 11-CURRENT

FreeBSD has just gotten dom0 support for the Xen hypervisor, something NetBSD has had for a while now
The ports tree will now have a Xen kernel and toolstack, meaning that they can be updated much more rapidly than if they were part of base
It’s currently limited to Intel boxes with EPT and a working IOMMU, running a recent version of the -CURRENT branch, but we’ll likely see it when 11.0 comes out
How will this affect interest in Bhyve?

A tale of two educational moments

Here we have a blog post from an OpenBSD developer about some experiences he had helping people get involved with the project
It’s split into two stories: one that could’ve gone better, and one that went really well
For the first one, he found that someone was trying to modify a package from their ports tree to have fewer dependencies
Experience really showed its worth, and he was able to write a quick patch to do exactly what the other person had been working on for a few hours – but wasn’t so encouraging about getting it committed
In the second story, he discussed updating a different port with a user of a forum, and ended up improving the new user’s workflow considerably with just a few tips
The lesson to take away from this is that we can all help out to encourage and assist new users – everyone was a newbie once

What’s coming in NetBSD 7

We first mentioned NetBSD 7.0 on the show in July of 2014, but it still hasn’t been released and there hasn’t been much public info about it
This blog post outlines some of the bigger features that we can expect to see when it actually does come out
Their total platform count is now over 70, so you’d be hard-pressed to find something that it doesn’t run on
There have been a lot of improvements in the graphics area, particularly with DRM/KMS, including Intel Haswell and Nouveau (for nVidia cards)
Many ARM boards now have full SMP support
Clang has also finally made its way into the base system, something we’re glad to see, and it should be able to build the base OS on i386, AMD64 and ARM – other architectures are still a WIP
In the crypto department: their PNRG has switched from the broken RC4 to the more modern ChaCha20, OpenSSL has been updated in base and LibreSSL is in pkgsrc
NetBSD’s in-house firewall, npf, has gotten major improvements since its initial debut in NetBSD 6.0
Looking to the future, NetBSD hopes to integrate a stable ZFS implementation later on

OpenZFS office hours

We mentioned a couple weeks back that the OpenZFS office hours series was starting back up
They’ve just uploaded the recording of their most recent freeform discussion, with Justin Gibbs being the main presenter
In it, they cover how Justin got into ZFS, running in virtualized environments, getting patches into the different projects, getting more people involved, reviewing code, spinning disks vs SSDs, defragging, speeding up resilvering, zfsd and much more

FreeBSD 10 as a firewall

Back in 2012, the author of this site wrote an article stating you should avoid FreeBSD 9 for a firewall and use OpenBSD instead
Now, with the release of 10.0, he\’s apparently changed his mind and switched back over
It mentions the SMP version of pf, general performance advantages and more modern features
The author is a regular listener of BSD Now, hi Joe!

Network Noise Reduction Using Free Tools

Really long blog post, based on a BSDCan presentation, about fighting spam with OpenBSD
Peter Hansteen, author of the book of PF, goes through how he uses OpenBSD\’s spamd and other security features to combat spam and malware
He goes through his experiences with content filtering and disappointment with a certain proprietary vendor
Not totally BSD-specific, lots of people can enjoy the article – lots of virus history as well

FreeBSD ASLR patches submitted

So far, FreeBSD hasn\’t had Address Space Layout Randomization
ASLR is a nice security feature, see wikipedia for more information
With a giant patch from Shawn Webb, it might be integrated into a future version (after a vicious review from the security team of course)
We might have Shawn on the show to talk about it, but he\’s also giving a presentation at BSDCan about his work with ASLR

Old-style pkg_ tools retired

At last the old pkg_add tools are being retired in FreeBSD
pkgng is a huge improvement, and now portmgr@ thinks it\’s time to cut the cord on the legacy toolset
Ports aren\’t going away, and probably never will, but for binary package fans and new users that are used to things like apt, pkgng is the way to go
All pkg_ tools will be considered unsupported on September 1, 2014 – even on older branches

News Roundup

FreeBSD on OpenStack

OpenStack is a cloud computing project
It consists of \”a series of interrelated projects that control pools of processing, storage, and networking resources throughout a datacenter, able to be managed or provisioned through a web-based dashboard, command-line tools, or a RESTful API.\”
Until now, there wasn\’t a good way to run a full BSD instance on OpenStack
With a project in the vein of Colin Percival\’s AWS startup scripts, now that\’s no longer the case!

FOSDEM BSD videos

This year\’s FOSDEM had seven BSD presentations
The videos are slowly being uploaded for your viewing pleasure
Not all of the BSD ones are up yet, but by the time you\’re watching this they might be!
Check this directory for most of \’em
The BSD dev room was full, lots of interest in what\’s going on from the other communities

The FreeBSD challenge finally returns!

Due to prodding from a certain guy of a certain podcast, the \”FreeBSD Challenge\” series has finally resumed
Our friend from the Linux foundation picks up with day 11 and day 12 on his switching from Linux journey
This time he outlines the upgrade process of going from 9 to 10, using freebsd-update
There\’s also some notes about different options for upgrading ports and some extra tips

PCBSD weekly digest

After the big 10.0 release, the PCBSD crew is focusing on bug fixes for a while
During their \”fine tuning phase\” users are encouraged to submit any and all bugs via the trac system
Warden got some fixes and the package manager got some updates as well
Huge size reduction in PBI format

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?
KM: How did the developer summit and hackathon go?
AJ: Where can people go to get involved with development, and what\’s currently needed?
KM: Anything else you\’d like to mention?
