374: OpenBSD’s 25th anniversary

JT Pennington — Thu, 29 Oct 2020 07:00:00 -0400

OpenBSD 6.8 has been released, NetBSD 9.1 is out, OpenZFS devsummit report, BastilleBSD’s native container management for FreeBSD, cleaning up old tarsnap backups, Michael W. Lucas’ book sale, and more.

NOTES

Headlines

OpenBSD 6.8

> Released Oct 18, 2020. (OpenBSD's 25th anniversary)

NetBSD 9.1 Released

> The NetBSD Project is pleased to announce NetBSD 9.1, the first update of the NetBSD 9 release branch. It represents a selected subset of fixes deemed important for security or stability reasons, as well as new features and enhancements.

OpenZFS Developer Summit 2020

> As with most other conferences in the last six months, this year’s OpenZFS Developer’s Summit was a bit different than usual. Held via Zoom to accommodate for 2020’s new normal in terms of social engagements, the conference featured a mix of talks delivered live via webinars, and breakout sessions held as regular meetings. This helped recapture some of the “hallway track” that would be lost in an online conference.
• After attending the conference, I wrote up some of my notes from each of the talks
• Part 2

News Roundup

BastilleBSD - native container management for FreeBSD

> Some time ago, I had the requirement to use FreeBSD in a project, and soon the question came up if Docker and Kubernetes can be used.
> On FreeBSD, Docker is not very well supported, and even if you can get it running, Linux is used in a Docker container. My experience with Docker on FreeBSD is awful, and so I started looking for alternatives.
> A quick search on one of the most significant online search engines led me to Jails and then to BastilleBSD.

Tarsnap – cleaning up old backups

> I use Tarsnap for my critical data. Case in point, I use it to backup my Bacula database dump. I use Bacula to backup my hosts. The database in question keeps track of what was backed up, from what host, the file size, checksum, where that backup is now, and many other items. Losing this data is annoying but not a disaster. It can be recreated from the backup volumes, but that is time consuming. As it is, the file is dumped daily, and rsynced to multiple locations.

MWL - BookSale

> For those interested in such things, I recently posted my 60,000th tweet. This prodded me to try an experiment I’ve been pondering for a while.
> Over at my ebookstore, two of my books are now on a “Name Your Own Price” sale. You can get git commit murder and PAM Mastery for any price you wish, with a minimum of $1.

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-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." ***

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
Be 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 ***

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

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
