Recent changes for virtual machine support and the new powerd utility have been rolled into the release branch for DragonFly. They’ll probably be in the next point release, or you can rebuild a release machine now for immediate access.
Also mentioned in the update from Matthew Dillon, DragonFly-master users should upgrade carefully as DragonFly migrates to using LibreSSL in base, and dports-based LibreSSL in dports.
Happy birthday to my younger daughter.
BSDNow episode 158 has an interview with Diane Bruce about ham radio and Raspberry Pi hardware, plus the usual news.
The’Errata 793‘ issue is apparently a bug where an AMD CPU can hang under very specific circumstances. Sepherosa Ziehau has a fix – please try it if you have the appropriate hardware.
How long does it take to build all 24,000 packages in the DragonFly ports collection? Apparently about 22 hours on a dual Xeon machine (with I think 36 cores) or 48-core Opteron. This is with synth. I used to measure pkgsrc builds in weeks.
DragonFly now has version 2.4.2 of LibreSSL and uses it in base. Ports may still link to OpenSSL, though – it’s still built by default, though make.conf can be configured to prevent that.
NYCBUG is meeting tomorrow night, with George Neville-Neil presenting DTrace work used as college-level teaching material, and talking about more places it could be used. Go if you are near New York City, interested in teaching, or you know – BSD. It’s in a different location than the normal monthly meetings.
This post fleshed out at the last minute, between road trips.
A week of travel didn’t get in the way of links! RSS feeds are still fantastic tools for those who know how to use them.
I’m a day late posting this because of travel, but: BSDNow 157 has an interview with Richard Yao about ZFS (on Linux?), and more story links. I found the “NetFlix and Fill” article link interesting – those are BSD appliances they are talking about that eat so much of the Internet’s traffic.
This makes sense once you think about it: copy-on-write filesystems (like Hammer2 and ZFS and probably others) actually do nothing when “zeroing” out filespace.
DragonFly-master (i.e. 4.7) now disables DSA keys by default. If you are using a DSA key for SSH/SFTP/whatever, you should change it anyway. Otherwise, it won’t work without workarounds after your next 4.7 upgrade, or by the time of the next DragonFly release.
GCC has been updated by John Marino from 5.3 to 5.4 in DragonFly – the 5.4 closed bug list on the GCC site is a good way to find out the benefits.
KnoxBUG’s next meeting is tomorrow night, and Mark Sumter is presenting on ZFS. Visit if you are near Tennessee.
Enjoy! I am going to have irregular network access over the next week, so this may be the only post for several days.
I don’t know how I ended up with 3 pfSense items to lead with – it just happened.
It’s been a very slow news week, but at least there’s a new BSDNow episode: The Fresh BSD Experience. There’s an interview with the FreeBSD Foundation intern, Drew Gurkowski, and a lot of ARM news.
Accidental nostalgia theme!
For once, I’m not working on Saturday, so even though this is last minute, at least I’m not in a race with the clock.
There’s been multiple reports of pulseaudio causing problems for DragonFly users. It would get pulled in as a dependency, and audio would suddenly stop working. Uninstall, and audio is fine. John Marino has removed it from dports, to prevent that exact problem.
BSDNow 155: no Allan, but an interview with Myke Geiger about using FreeBSD in an ISP role, and a bunch of news items.
There’s been a number of commits lately around higher optimization levels for your DragonFly kernel. It looks you can even set it systemwide. Boot code remains at -O; any higher level will make it explode. Is this safe? I have no idea!
If you are on DragonFly-current, AKA DragonFly 4.7, make sure to perform a full buildworld on your next upgrade. Tomohiro Kusumi changed a Hammer ioctl, and the buildworld is needed to keep everything in sync.
A manageable batch of links this week.

The Lumina release is the highlight of the week.
It’s a good week to learn: BSDNow 154 has no interview, but a lot of tutorials, including ones on GhostBSD, Enlightenment, Steam on FreeBSD, and so on.
The last bits of Linux emulation have been removed from DragonFly. It’s 32-bit, so it’s been unsupported since DragonFly went to 64-bit only with the 4.0 release. Also, some other 32-bit only items are gone, including the cs, ep, ex, fe, and vx network drivers. It’s almost impossible that anyone was using it, but it’s notable because that’s some… 15-20k lines of code gone? Removal of unused code is also positive.
Alex Merritt noticed that one of the new characteristics of DragonFly 4.6 was “improved IPI signalling”. He asked about benchmarks, Sepherosa Ziehau pointed at tools, and Matthew Dillon provided some results.
Because this always happens just after I create a DragonFly release, there’s a new version of OpenSSL. However, this is for version 1.0.2. 1.0.1 is what’s in the release, and it’s supported through the end of the year.
OpenSSH has a major version bump in DragonFly, to 7.3p1. This means some features – specifically patches for High Performance Networking – are no longer there, and you’ll get an error if your config file requires them. Either remove the options from your config, or install OpenSSH from dports.
Did you know that ACPICA has its own internal ‘coding language’, called AML? I did not, but it’s in DragonFly now in any case. Every program eventually grows big enough to read email, and every specification eventually includes its own programming segment.
If you’re one of the people who can easily read ‘systat -vm’ output, the data presented there has been modified. If you’re not one of those people, it’s a good way to monitor system health.
Getting esoteric this week.

Garbage 37 is out, with talk about their format and timing, OpenBSD material, and more Chromebook discussion.
Here is some coverage of the DragonFly 4.6 release, which may be interesting to read because of the comments: Hacker News, Hacker News again, and lobste.rs.
A reaction to the initial creation of DragonFly I never saw before, and Matthew Dillon’s followup. (via)
I like the summary in the very first comment of this story on DragonFly removing page-zeroing.
It’s Thursday, so that means BSDNow 153, with a title inspired by the lead news item, “my int is too big”. (No, not spoon, int.) No interview this week, but lots of links.
Thanks to a reminder from IRC user ‘cgag’, I’ve put an uncompressed ISO image of DragonFly 4.6 up on the main site. It’s linked on the download page, and should be available within 24 hours on the mirrors. If you are buying service from a virtual host provider, and can install an operating system directly from a downloadable URL, this is for you.
After some testing of different ways to pre-zero out memory pages, Matthew Dillon came to the conclusion: page zeroing doesn’t matter any more. The idea dates all the way back to CSRG, and he’s removed it from DragonFly.
DragonFly 4.6 is officially released! Download from your nearest mirror, or update your source files and build – my users@ email describes the steps.
If you are near New York City, NYCBUG’s InstallFest is happening just before 7 PM Wednesday at the usual Stone Creek bar meeting location. Go, see what strange hardware turns up.
A mix of hard thinking and jokes today.

I did all of this in a hour, because I had so many tabs saved from during the week. Don’t get overwhelmed!
Bonus DragonFly items, sent by Rolinh on IRC:
Recently published: BSDNow 152, “The Laporte has landed!“, with an interview of Leo Laporte and his move to BSD, and also garbage, with some OpenBSD release conversation scattered in there.
I’m a bit late on this, but: If you are using DragonFly-current, you will need to rebuild world. If you are on 4.4, this won’t matter until you go to 4.6, and you’d be rebuilding world and kernel for that anyway.
(4.6 will probably be tagged this weekend.)
DragonFly 4.6 release candidate 2 has been tagged. You can pull it directly from the master site in img or iso form (check your local mirror instead if possible), or shift to the new tag.
“Where is RC1?” you may ask? I tagged the first release candidate some days ago, and this bug was immediately found right after. It was easier to go right to RC2 once a fix was found.
This candidate will probably lead directly to a release version, so if you want to run the release version exactly, wait a few days.
Off-the-beaten-path links this week. Strap in!
Your unrelated animated GIF of the week: Permanent Wink.
Adding a new “BUG” category, cause there’s enough ongoing BSD user group activity these days that it’s a reoccurring theme. That makes me happy.
Matthew Dillon added NVMe support recently, and he also made some changes to DragonFly’s I/O system. His test system was able to reach over a million IOPS. That’s bananas!
Garbage 35 is up, with news about ChiBUG, an OpenBSD hackathon, and the ritual shaming of computer equipment.
HOPE starts today in New York City, and if you are going, there’s at least one BSD presence at the show that could use volunteers.
Fuzzing sounds cute, but it’s about finding security problems, not checking for adorable guinea pigs or llamas or something like that. It’s also episode 151 of BSDNow. It looks like there’s no specific interview this week, but plenty of interesting topics and links listed.
the i915 support in DragonFly now matches the Linux 4.4 kernel, which is good news if you have a Broxton, Skylake, or Cherryview processor, plus it adds a variety of fixes.
If you want to check battery life, ‘sysctl hw.acpi.battery.life’ may help, as Sepherosa Ziehau points out. I’ve always used ‘acpiconf -i 0‘, myself.
I like finding “This is how I did it” stories from people, as they are often really useful for anyone else trying to do the same “it”. Here’s Dave MacFarlane’s UEFI install story. (Note he’s still needing touchpad support.)
It’s a nerdy Lazy Reading today. Well, nerdier than usual, I think.
A useful tip: if your DragonFly machine isn’t usually on 24/7 (e.g. a laptop, not a server), you should move your Hammer cleanup from 3 AM to sometime when the computer is normally on.
Among other things, garbage brings up joshua stein’s desire to form a BSD user group near Chicago – contact him if you’re near.
BSDNow has reached their I think semicentennial episode, “Sprinkle A Little BSD Into Your Life“. For this episode, they interview Jim Brown about BSD Certification and his FreeBSD-running sprinkler system, plus more news.
karu.pruun shares a story of manually installing DragonFly on a UEFI-booting machine. In this case, it’s a Macbook, though there’s other non-fruit UEFI machines out there?
That’s one tip per subject, really. If you need to set up a ‘video’ group for xorg, here’s the one-liner to do so. If PulseAudio annoys you, which is not uncommon, ‘chmod -x /usr/local/bin/pulseaudio’ and it’ll go away.
It’s exactly what the title is: ipfw3 now does NAT in-kernel, without locking. I have no benchmarks to point at, unfortunately. The commit has usage examples.
This is a specialized use case, but Mono 4.x has some issues on DragonFly. Some minor testing has been done, but if you are already using it, please contribute.
Assembled hastily on Saturday, which is later than I’ve been in a long time.

I was on the road all this week, so this doesn’t range as far as usual. I’ll be charging through my RSS feed backlog over the next few days.
The NYCBUG meeting happening tomorrow night, June 6th, is on the two different BSDs (RetroBSD and LiteBSD) that can run on the super-tiny PIC32 microcontroller. Go if you are near.

Lots of user group items this week.
The system I had for running a go builder died. I am running out of extra hardware. Is there someone who is using Go and DragonFly and is willing to commit to running a semi-dedicated builder?
I’m actually linking to this week’s Garbage podcast on time. They have shirts coming in now!
This weeks’ BSDNow has an interview with Edicarla Andrade & Vinícius Zavam about FreeBSD-powered robots. Yep, robots. There’s other news there too, but it’s not as interesting unless it is about lasers.
There’s a new digital library in Kisumu, Kenya – and it’s running DragonFly for file storage.
Hammer2 now has inode indexing, which Matthew Dillon was avoiding while trying to create more efficient hardlink support. The result is now with that problem solved, more updates can come in: NFS support, mtime updates, output changes, code removal, and lots of other changes, not all of which I’m even linking.
If you have a NVMe chipset under DragonFly, you now can use a special utility to retrieve status information: nvmectl. Right now, only ‘info’ is implemented.
I was traveling and completely missed this, even though it’s on a regular schedule: garbage: Pirates of the Corebootean.
If you are running DragonFly 4.5 (i.e. bleeding edge), Sepherosa Ziehau made an ifnet change that will require a full buildkernel/world if you want things like netstat to keep working.
Did this early too, but ended up with lots of links.
A good amount of user group material this week.
