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%.

I’m hitting every type of BSD this week.
If you have iwm(4) network hardware, that driver now supports some more chipsets, plus it’s had some other updates, courtesy of Imre Vadasz.
(I think I spelled Imre’s name right for once!)
Friday’s garbage podcast is up, this one being number 29. It’s a one-man show this week, but you get to hear about joshua’s experience booting OpenBSD on an HP Chromebook 13.
The South East Linux Fest is starting tomorrow, and there will be a BSD presence (booth and talks) there – PC-BSD. Stop by if you are the Charlotte, NC area.
(I’d normally save this for In Other BSDs but the event would be half-done by then.)
BSDNow 145 has, along with a number of BSD links, an interview with Benno Rice. Rice works at Isilon/EMC which uses FreeBSD as their underlying storage platform.
Matthew Dillon has been testing on more NVMe hardware, or at least what is supposed to be NVMe hardware, and he has a writeup of the results that may be useful for anyone planning a shopping trip soon.
Remember Sepherosa Ziehau’s nginx tests on DragonFly? He’s using the same configuration to test performance of the accept(2) and close(2) calls. The result? Over 8000 concurrent connections, for 580,000 connections per second. That’s on one DragonFly machine.
Matthew Dillon has written a new, from scratch, driver for NMVe in DragonFly. If you haven’t encountered it yet, that’s SSD access over PCIe, which gives better throughput than ATA. He’s posted a summary of his work, and it’s possible to load it now as a module. It supports MSI-X, and there’s test results from using dd on supported NVMe hardware.
I managed to not post about BSDNow (144: The PF Life) or garbage (running with scissors for a while) last week, so I’m posting them now. That’s about 2 hours of BSD-ish conversation for you to listen to before this week’s episodes roll out.
This week is Esoterica week, for Lazy Reading.
Really, last minute – assembled from random tabs I’ve been saving, late Friday.
Tomohiro Kusumi has finished his port of autofs to DragonFly; you can now have a filesystem automatically mount when accessed, rather than requiring it at boot.
If you are running DragonFly in a virtual environment, there’s been some improvements to virtio(4). Update and try if you’ve had problems in the past.
It’s a Solaris episode – or to be exact, SunOS, on BSDTalk this week. Sun used to be BSD, up to version 4.1.4, and this is 17 minutes of talk about that version.
Sepherosa Ziehau has been working on network performance, including making more network calls asynchronous. His test case using nginx shows that a single DragonFly machine can now take enough traffic to max out 2 10Gb links. That’s with 16Kb requests, and 30,000 of them at the same time.
What are people using for a web framework these days? I was messing with Fat Free Framework, and there seems to be about a zillion options, for many languages, these days.
Your unrelated comics link of the week: The Digital Comics Museum.
The garbage podcast is out, and it’s covering OpenBSD, iOS, and Android topics, or at least that’s what I guess from the summary, cause I’m still at work.
If you have a ral(4) wireless card that didn’t function as expected, it may suddenly work for you now on DragonFly 4.5 due to the large wifi update. The ral(4) driver covers a lot of hardware, so check the man page for all the commercial names.
BSDNow 143 has the usual roundup of news, plus a conversation with Matthew Macy about graphics improvements in FreeBSD.
We need DragonFly people interviewed, since DragonFly graphics improvements have been leading the pack, so to speak. I’m linking to the Jupiter Broadcasting site again since I don’t see this episode up on the BSDNow site yet.
A reminder: Dru Lavigne is talking at KnoxBUG tomorrow (the 26th) at 6 PM. I’ve met Dru and she’s a good speaker with a wide range of experience – catch it if you are anywhere near.
Matthew Dillon and Adrian Chadd have updated the wifi setup in DragonFly, incorporating Adrian’s FreeBSD changes (and merging back some of Matt’s from DragonFly). This affects the ath, rum, iwm, iwn, run, bwn, urtwn, wi, ral, iwi, ndis, and wpi drivers. The ‘an’ driver has been removed, too. I’m not going to even try to link to all the commits.
If you’re on DragonFly master and are using one of these devices, now is the time to update and try. Note that this removes the separate network interface that’s specific to the device and creates only a wlanX device.
Update: Matt reminded me that at least half the work came from Imre Vadasz; I missed it because I was only looking at the commit email names – mea culpa.
Read this email thread for how to mount devices (e.g. USB drives) in DragonFly when you aren’t root.
A nice wide range of topics, again!
Summer convention season is coming; start scheduling!
karu.pruun managed to get xwayland working on DragonFly, and also took notes while doing it. That means you can try it out, too.
