OpenZFS with ZSTD land in FreeBSD 13

• ZStandard Compression for OpenZFS > The primary benefit is maintaining a completely shared code base with the community allowing FreeBSD to receive new features sooner and with less effort. > I would advise against doing 'zpool upgrade' or creating indispensable pools using new features until this change has had a month+ to soak.
• Rebasing FreeBSD’s OpenZFS on the new upstream was sponsored by iXsystems
• The competition of ZSTD support for OpenZFS was sponsored by the FreeBSD Foundation ***

LibreSSL documentation status update

More than six years ago, LibreSSL was forked from OpenSSL, and almost two years ago, i explained the status of LibreSSL documentation during EuroBSDCon 2018 in Bucuresti. So it seems providing an update might be in order.
Note that this is not an update regarding LibreSSL status in general because i'm not the right person to talk about the big picture of working on the LibreSSL code, my work has been quite focussed on documentation. All the same, it is fair to say that even though the number of developers working on it is somewhat limited, the LibreSSL project is quite alive, typically having a release every few months. Progress continues being made with respect to porting and adding new functionality (for example regarding TLSv1.3, CMS, RSA-PSS, RSA-OAEP, GOST, SM3, SM4, XChaCha20 during the last two years), OpenSSL compatibility improvements (including providing additional OpenSSL-1.1 APIs), and lots of bug fixes and code cleanup.

FreeBSD on SPARC64 (is dead)

’m coming pretty late to the party, because SPARC64 support in FreeBSD is apparently doomed: After the POWER platform made the switch to a LLVM/Clang-based toolchain, SPARC64 is one of the last ones that still uses the ancient GCC 4.2-based toolchain that the project wants to finally get rid off (it has already happened as I was writing this – looks like the firm plan was not so firm after all, since they killed it off early). And compared to the other platforms it has seen not too much love in recent times… SPARC64 being a great platform, I’d be quite sad to see it go. But before that happens let’s see what the current status is and what would need to be done if it were to survive, shall we?

News Roundup

Bringing zpool checkpoints to a FreeBSD bootloader

Almost two years ago I wrote a blog post about checkpoints in ZFS. I didn’t hide that I was a big fan of them. That said, after those two years, I still feel that there are underappreciated features in the ZFS world, so I decided to do something about that.
Currently, one of the best practices for upgrading your operating system is to use boot environments. They are a great feature for managing multiple kernels and userlands. They are based on juggling which ZFS datasets are mounted. Each dataset has its own version of the system. Unfortunately, boot environments have their limitations. If we, for example, upgrade our ZFS pool, we may not be able to use older versions of the system anymore.
The big advantage of boot environments is that they have very good tools. Two main tools are beadm (which was created by vermaden) and bectl (which currently is in the FreeBSD base system). These tools allow us to create and manage boot environments.

Password gropers take spamtrap bait

• Our friend Peter Hansteen, who keeps his eyes glued to his log files, has a new blog post
• He seems to have discovered another new weird phenomenon in his pop3 logs
• "yes, I still run one, for the same bad reasons more than a third of my readers probably do: inertia"
• Someone tried to log in to his service with an address that was known to be invalid
• The rest of the post goes into detail about his theory of why someone would use a list of invalid addresses for this purpose ***

Inside the Atheros wifi chipset

Defend your network and privacy, FreeBSD version

• Back in episode 39, we covered a blog post about creating an OpenBSD gateway - partly based on our tutorial
• This is a follow-up post, by the same author, about doing a similar thing with FreeBSD
• He mentions some of the advantages and disadvantages between the two operating systems, and encourages users to decide for themselves which one suits their needs
• The rest is pretty much the same things: firewall, VPN, DHCP server, DNSCrypt, etc. ***

Don't encrypt all the things

• Another couple of interesting blog posts from Ted Unangst about encryption
• It talks about how Google recently started ranking sites with HTTPS higher in their search results, and then reflects on how sometimes encryption does more harm than good
• After heartbleed, the ones who might be able to decrypt your emails went from just a three-letter agency to any script kiddie
• He also talks a bit about some PGP weaknesses and a possible future replacement
• He also has another, similar post entitled "in defense of opportunistic encryption" ***

New automounter lands in FreeBSD

• The work on the new automounter has just landed in 11-CURRENT
• With help from the FreeBSD Foundation, we'll have a new "autofs" kernel option
• Check the SVN viewer online to read over the man pages if you're not running -CURRENT
• You can also read a bit about it in the recent newsletter ***

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

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

• Check our interview with GNN for more information about the journal ***

OpenSSL, more like OpenSS-Hell

• We mentioned this huge OpenSSL bug last week during all the chaos, but the aftermath is just as messy
• There's been a pretty vicious response from security experts all across the internet and in all of the BSD projects - and rightfully so
• We finally have a timeline of events
• Reactions from ISC, PCBSD, Tarsnap, the Tor project, FreeBSD, NetBSD, oss-sec, PHK, Varnish and Akamai
• pfSense released a new version to fix it
• OpenBSD disabled heartbeat entirely and is very unforgiving of the IETF
• Ted Unangst has two good write-ups about the issue and how horrible the OpenSSL codebase is
• A nice quote from one of the OpenBSD lists: "Given how trivial one-liner fixes such as #2569 have remained unfixed for 2.5+ years, one can only assume that OpenSSL's bug tracker is only used to park bugs, not fix them"
• Sounds like someone else was having fun with the bug for a while too
• There's also another OpenSSL bug that OpenBSD patched - it allows an attacker to inject data from one connection into another
• OpenBSD has also imported the most current version of OpenSSL and are ripping it apart from the inside out - we're seeing a fork in real time ***

Portable signify

• Back in episode 23 we talked with Ted Unangst about the new "signify" tool in OpenBSD
• Now there's a (completely unofficial) portable version of it on github
• If you want to verify your OpenBSD sets ahead of time on another OS, this tool should let you do it
• Maybe other BSD projects can adopt it as a replacement for gpg and incorporate it into their base systems ***

• 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
• All commits to this branch require approval of portmgr, looks like it'll start in 2014Q1 ***
