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.
Your unrelated link of the week: Mea Culpa. (via)
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.
Half of this was done while trapped in day 3 of a 3-day planning and training meeting at work.

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.
This is limited to some users of specific Intel video chipsets, but: if you get odd screen artifacts in X, the ‘vesa’ driver may work just fine for you. Or turn acceleration off. Or set ‘drm.i915.enable_execlists=0’ according to zrj on #dragonflybsd.
(Updated to reflect all the answers in the thread and elsewhere.)
BSDNow 147 is available, with an interview of Glen Barber and Peter Wemm. They’re talking about release engineering, as you may have guessed from the title.
If you didn’t already know about it, you will find this useful: DragonFly has a tuning(7) man page, about getting the best performance from your system. Matthew Dillon recently updated the man page with some tips about SSD setup.
Tomohiro Kasumi wrote a lengthy explanation of what “@@” means, in the context of the Hammer file system. It acts as a sort of signifier for each actual Hammer pseudo-file-system, since it’s possible to null-mount these anywhere in DragonFly, under all sorts of names. Don’t trust my summary, though – read his.
Sepherosa Ziehau needs to run DragonFly under Hyper-V at work, so he’s making improvements .
I got me a retro Teasmade, so as you read this, I’m probably waking up to a fresh cup. It’s not very practical, but it is fun.

If you didn’t already look at it, BSDNow’s summary of BSDCan events is worth going to; it’s complete enough I deliberately left BSDCan links out of here. Undeadly has an OpenBSD-specific summary too.
garbage has BSDCan trip reports, OpenBSD news, and complaints about CVS, among other things. CVS is an easy target but I want to hear it.
There are USB devices out there that are sort of like a mouse, as in they work as a pointing device, but they don’t show up as a mouse device. For example, the PowerMate USB Multimedia Controller. It’s possible to pipe the events from this or similar ‘weird’ devices to sysmouse, and use it the way you’d expect, with this fix from user tautology.
BSDNow episode 146 is available, with an interview of Hans Petter Selasky about USB and FreeBSD. There’s also a nice collection of links to BSDCan material, including video from the event.
As part of his NVMe work, Matthew Dillon found I/O speed so fast that CRC checking actually got in the way of disk activity. He’s brought in a new CRC algorithm called xxHash. He also brought in Mark Adler’s hardware iscsi_crc32 implementation, but did not add it to Hammer2. There’s some work on read-ahead operations too, to deal with the NVMe throughput.
(Posting earlier than the usual ‘In Other BSDs’ content, because it’s happening tomorrow.)
NYCBUG is meeting tomorrow, June 15 at 18:45 Eastern time. It’ll be at Stone Creek Bar & Lounge, 140 E 27th St. in New York City. The speaker is Shawn Webb, and he’ll be talking about his HardenedBSD work in “Adventures in HardenedBSD”.
Remember how DragonFly now has autofs? That obsoletes amd, amq, and so on, in the am-utils suite. Now, am-utils has been removed. This may affect nobody, as am-utils wasn’t working well.
Did you know there’s a rescue image, created with crunchgen, in DragonFly? If your system can boot to single-user mode, you can use it to at least manipulate data on disk – it includes mined as a simple small editor. (Since vi assumes /usr is mountable.) This rescue image now includes undo, so you can back out changes on a Hammer volume.
Covering all the bases – history, UNIX, D&D, editors. No tea links, so I guess I’m not scoring 100%.
