EdgeRouter Lite, meet OpenBSD

• The ERL, much like the Raspberry Pi and a bunch of other cheap boards, is getting more and more popular as more things get ported to run on it
• We've covered installing NetBSD and FreeBSD on them before, but OpenBSD has gotten a lot better support for them as well now (including the onboard storage in 5.8)
• Ted Unangst got a hold of one recently and kindly wrote up some notes about installing and using OpenBSD on it
• He covers doing a network install, getting the (slightly strange) bootloader working with u-boot and some final notes about the hardware
• More discussion can be found on Hacker News and various other places
• One thing to note about these devices: because of their MIPS64 processor, they'll have weaker ASLR than X86 CPUs (and no W^X at all) ***

Design and Implementation of the FreeBSD Operating System interview

• For those who don't know, the "Design and Implementation of the FreeBSD Operating System" is a semi-recently-revived technical reference book for FreeBSD development
• InfoQ has a review of the book up for anyone who might be interested, but they also have an interview the authors
• "The book takes an approach to FreeBSD from inside out, starting with kernel services, then moving to process and memory management, I/O and devices, filesystems, IPC and network protocols, and finally system startup and shutdown. The book provides dense, technical information in a clear way, with lots of pseudo-code, diagrams, and tables to illustrate the main points."
• Aside from detailing a few of the chapters, the interview covers who the book's target audience is, some history of the project, long-term support, some of the newer features and some general OS development topics ***

Path list parameter in OpenBSD tame

• We've mentioned OpenBSD's relatively new "tame" subsystem a couple times before: it's an easy-to-implement "self-containment" framework, allowing programs to have a reduced feature set mode with even less privileges
• One of the early concerns from users of other process containment tools was that tame was too broad in the way it separated disk access - you could either read/write files or not, nothing in between
• Now there's the option to create a whitelist of specific files and directories that your binary is allowed to access, giving a much finer-grained set of controls to developers
• The next step is to add tame restraints to the OpenBSD userland utilities, which should probably be done by 5.9
• More discussion can be found on Reddit and Hacker News ***

FreeBSD & PC-BSD 10.2-RELEASE

• The FreeBSD team has released the second minor version bump to the 10.x branch, including all the fixes from 10-STABLE since 10.1 came out
• The Linux compatibility layer has been updated to support CentOS 6, rather than the much older Fedora Core base used previously, and the DRM graphics code has been updated to match Linux 3.8.13
• New installations (and newly-upgraded systems) will use the quarterly binary package set, rather than the rolling release model that most people are used to
• A VXLAN driver was added, allowing you to create virtual LANs by encapsulating the ethernet frame in a UDP packet
• The bhyve codebase is much newer, enabling support for AMD CPUs with SVM and AMD-V extensions
• ARM and ARM64 code saw some fixes and improvements, including SMP support on a few specific boards and support for a few new boards
• The bootloader now supports entering your GELI passphrase before loading the kernel in full disk encryption setups
• In addition to assorted userland fixes and driver improvements, various third party tools in the base system were updated: resolvconf, ISC NTPd, netcat, file, unbound, OpenSSL, sendmail
• Check the full release notes for the rest of the details and changes
• PC-BSD also followed with their 10.2-RELEASE, sporting a few more additional features ***

NetBSD at Open Source Conference Shimane

• We weren't the only ones away at conferences last week - the Japanese NetBSD guys are always raiding one event or another
• This time they had NetBSD running on some Sony NWS devices (MIPS-based)
• JavaStations were also on display - something we haven't ever seen before (made between 1996-2000) ***

BAFUG videos

• The Bay Area FreeBSD users group has been uploading some videos of their recent meetings
• Devin Teske hosts the first one, discussing adding GELI support to the bootloader, including some video demonstrations of how it works
• Shortly after beginning, Adrian Chadd takes over the conversation and they discuss various problems (and solutions) related to the bootloader - for example, how can we type encryption passwords with non-US keyboard layouts
• In a second video, Jordan Hubbard and Kip Macy introduce "NeXTBSD aka FreeBSD X"
• In it, they discuss their ideas of merging more Mac OS X features into FreeBSD (launchd to replace the init system, some APIs, etc)
• People should record presentations at their BSD users groups and send them to us ***

L2TP over IPSEC on OpenBSD

• If you've got an OpenBSD box and some Mac OS X clients that need secure communications, surprise: they can work together pretty well
• Using only the base tools in both operating systems, you can build a nice IPSEC setup for tunneling all your traffic
• This guide specifically covers L2TP, using npppd and pre-shared keys
• Server setup, client setup, firewall configuration and routing-related settings are all covered in detail ***

Reliable bare metal with TrueOS

• Imagine a server version of PC-BSD with some useful utilities preinstalled - that's basically TrueOS
• This article walks you through setting up a FreeBSD -CURRENT server (using TrueOS) to create a pretty solid backup solution
• Most importantly, he also covers how to keep everything redundant and deal with hard drives failing
• The author chose to go with the -CURRENT branch because of the delay between regular releases, and newer features not making their way to users as fast as he'd like
• Another factor is that there are no binary snapshots of FreeBSD -CURRENT that can be easily used for in-place upgrades, but with TrueOS (and some other BSDs) there are ***

Kernel W^X on i386

• We mentioned some big W^X kernel changes in OpenBSD a while back, but the work was mainly for x86_64 CPU architecture (which makes sense; that's what most people run now)
• Mike Larkin is back again, and isn't leaving the people with older hardware out, committing similar kernel work into the i386 platform now as well
• Check out our interview with Mike for some more background info on memory protections like W^X ***

BSD panel at Phoenix LUG

• The Phoenix, Arizona Linux users group had a special panel so they could learn a bit more about BSD
• It had one FreeBSD user and one OpenBSD user, and they answered questions from the organizer and the people in the audience
• They covered a variety of topics, including filesystems, firewalls, different development models, licenses and philosophy
• It was a good "real world" example of things potential switchers are curious to know about
• They closed by concluding that more diversity is always better, and even if you've got a lot of Linux boxes, putting a few BSD ones in the mix is a good idea ***

Book of PF signed copy auction

• Peter Hansteen (who we've had on the show) is auctioning off the first signed copy of the new Book of PF
• All the profits from the sale will go to the OpenBSD Foundation
• The updated edition of the book includes all the latest pf syntax changes, but also provides examples for FreeBSD and NetBSD's versions (which still use ALTQ, among other differences)
• If you're interested in firewalls, security or even just advanced networking, this book is a great one to have on your shelf - and the money will also go to a good cause
• Michael Lucas has challenged Peter to raise more for the foundation than his last book selling - let's see who wins
• Pause the episode, go bid on it and then come back! ***

FreeBSD Foundation goes to EuroBSDCon

• Some people from the FreeBSD Foundation went to EuroBSDCon this year, and come back with a nice trip report
• They also sponsored four other developers to go
• The foundation was there "to find out what people are working on, what kind of help they could use from the Foundation, feedback on what we can be doing to support the FreeBSD Project and community, and what features/functions people want supported in FreeBSD"
• They also have a second report from Kamil Czekirda
• A total of $2000 was raised at the conference ***

OpenBSD 5.6 released

• Note: we're doing this story a couple days early - it's actually being released on November 1st (this Saturday), but we have next week off and didn't want to let this one slip through the cracks - it may be out by the time you're watching this
• Continuing their always-on-time six month release cycle, the OpenBSD team has released version 5.6
• It includes support for new hardware, lots of driver updates, network stack improvements (SMP, in particular) and new security features
• 5.6 is the first formal release with LibreSSL, their fork of OpenSSL, and lots of ports have been fixed to work with it
• You can now hibernate your laptop when using a fully-encrypted filesystem (see our tutorial for that)
• ALTQ, Kerberos, Lynx, Bluetooth, TCP Wrappers and Apache were all removed
• This will serve as a "transitional" release for a lot of services: moving from Sendmail to OpenSMTPD, from nginx to httpd and from BIND to Unbound
• Sendmail, nginx and BIND will be gone in the next release, so either migrate to the new stuff between now and then or switch to the ports versions
• As always, 5.6 comes with its own song and artwork - the theme this time was obviously LibreSSL
• Be sure to check the full changelog (it's huge) and pick up a CD or tshirt to support their efforts
• If you don't already have the public key releases are signed with, getting a physical CD is a good "out of bounds" way to obtain it safely
• Here are some cool images of the set
• After you do your installation or upgrade, don't forget to head over to the errata page and apply any patches listed there ***

Updating FreeBSD's IPSEC stack

News Roundup

Clang in DragonFly BSD

• As we all know, FreeBSD got rid of GCC in 10.0, and now uses Clang almost exclusively on i386/amd64
• Some DragonFly developers are considering migrating over as well, and one of them is doing some work to make the OS more Clang-friendly
• We'd love to see more BSDs switch to Clang/LLVM eventually, it's a lot more modern than the old GCC most are using ***

reallocarray(): integer overflow detection for free

• One of the less obvious features in OpenBSD 5.6 is a new libc function: "reallocarray()"
• It's a replacement function for realloc(3) that provides integer overflow detection at basically no extra cost
• Theo and a few other developers have already started a mass audit of the entire source tree, replacing many instances with this new feature
• OpenBSD's explicit_bzero was recently imported into FreeBSD, maybe someone could also port over this too ***

Switching from Linux blog

• A listener of the show has started a new blog series, detailing his experiences in switching over to BSD from Linux
• After over ten years of using Linux, he decided to give BSD a try after listening to our show (which is awesome)
• So far, he's put up a few posts about his initial thoughts, some documentation he's going through and his experiments so far
• It'll be an ongoing series, so we may check back in with him again later on ***

Owncloud in a FreeNAS jail

• One of the most common emails we get is about running Owncloud in FreeNAS
• Now, finally, someone made a video on how to do just that, and it's even jailed
• A member of the FreeNAS community has uploaded a video on how to set it up, with lighttpd as the webserver backend
• If you're looking for an easy way to back up and sync your files, this might be worth a watch ***

pfSense 2.1.4 released

• The pfSense team has released 2.1.4, shortly after 2.1.3 - it's mainly a security release
• Included within are eight security fixes, most of which are pfSense-specific
• OpenSSL, the WebUI and some packages all need to be patched (and there are instructions on how to do so)
• It also includes a large number of various other bug fixes
• Update all your routers! ***

DragonflyBSD's pf gets SMP

• While we're on the topic of pf...
• Dragonfly patches their old[er than even FreeBSD's] pf to support multithreading in many areas
• Stemming from a user's complaint, Matthew Dillon did his own work on pf to make it SMP-aware
• Altering your configuration's ruleset can also help speed things up, he found
• When will OpenBSD, the source of pf, finally do the same? ***

ChaCha usage and deployment

• A while back, we talked to djm about some cryptography changes in OpenBSD 5.5 and OpenSSH 6.5
• This article is sort of an interesting follow-up to that, showing which projects have adopted ChaCha20
• OpenSSH offers it as a stream cipher now, OpenBSD uses it for it's random number generator, Google offers it in TLS for Chromium and some of their services and lots of other projects seem to be adopting it
• Both Google's fork of OpenSSL and LibReSSL have upcoming implementations, while vanilla OpenSSL does not
• Unfortunately, this article has one mistake: FreeBSD does not use it - they still use the broken RC4 algorithm ***

BSDMag June 2014 issue

• The monthly online BSD magazine releases their newest issue
• This one includes the following articles: TLS hardening, setting up a package cluster in MidnightBSD, more GIMP tutorials, "saving time and headaches using the robot framework for testing," an interview and an article about the increasing number of security vulnerabilities
• The free pdf file is available for download as always ***

Preauthenticated decryption considered harmful

• Responding to a post from Adam Langley, Ted Unangst talks a little more about how signify and pkg_add handle signatures
• In the past, the OpenBSD installer would pipe the output of ftp straight to tar, but then verify the SHA256 at the end - this had the advantage of not requiring any extra disk space, but raised some security concerns
• With signify, now everything is fully downloaded and verified before tar is even invoked
• The pkg_add utility works a little bit differently, but it's also been improved in this area - details in the post
• Be sure to also read the original post from Adam, lots of good information ***

FreeBSD 9.3-RC2 is out

• As the -RELEASE inches closer, release candidate 2 is out and ready for testing
• Since the last one, it's got some fixes for NIC drivers, the latest file and libmagic security fixes, some serial port workarounds and various other small things
• The updated bsdconfig will use pkgng style packages now too
• A lesser known fact: there are also premade virtual machine images you can use too ***

pkgsrcCon 2014 wrap-up

• In what may be the first real pkgsrcCon article we've ever had!
• Includes wrap-up discussion about the event, the talks, the speakers themselves, what they use pkgsrc for, the hackathon and basically the whole event

OpenSSH 6.5 released

• We mentioned the CFT last week, and it's finally here!
• New key exchange using elliptic-curve Diffie Hellman in Daniel Bernstein's Curve25519 (now the default when both clients support it)
• Ed25519 public keys are now available for host keys and user keys, considered more secure than DSA and ECDSA
• Funny side effect: if you ONLY enable ed25519 host keys, all the compromised Linux boxes can't even attempt to login lol~
• New bcrypt private key type, 500,000,000 times harder to brute force
• Chacha20-poly1305 transport cipher that builds an encrypted and authenticated stream in one
• Portable version already in FreeBSD -CURRENT, and ports
• Lots more bugfixes and features, see the full release note or our interview with Damien
• Work has already started on 6.6, which can be used without OpenSSL! ***

Crazed Ferrets in a Berkeley Shower

• In 2000, MWL wrote an essay for linux.com about why he uses the BSD license: "It’s actually stood up fairly well to the test of time, but it’s fourteen years old now."
• This is basically an updated version about why he uses the BSD license, in response to recent comments from Richard Stallman
• Very nice post that gives some history about Berkeley, the basics of the BSD-style licenses and their contrast to the GNU GPL
• Check out the full post if you're one of those people that gets into license arguments
• The takeaway is "BSD is about making the world a better place. For everyone." ***

• Ok bapt, do it ***

The FreeBSD challenge continues

• Checking in with our buddy from the Linux foundation...
• The switching from Linux to FreeBSD blog series continues for his month-long trial
• Follow up from last week: "As a matter of fact, I did check out PC-BSD, and wanted the challenge. Call me addicted to pain and suffering, but the pride and accomplishment you feel from diving into FreeBSD is quite rewarding."
• Since we last mentioned it, he's decided to go from a VM to real hardware, got all of his common software installed, experimented with the Linux emulation, set up virtualbox, learned about slices/partitions/disk management, found BSD alternatives to his regularly-used commands and lots more ***

Ports gets a stable branch

• For the first time ever, FreeBSD's ports tree will have a maintained "stable" branch
• This is similar to how pkgsrc does things, with a rolling release for updated software and stable branch for only security and big 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! ***
