Rimvydas Jasinskas has consolidated/restored/updated a large number of papers into share/doc on DragonFly. I’m not going to link to his large number of commits, but instead point you at the directory where they all went. There’s a number of design documents in there that date back to 4.4BSD and beyond (and some much newer), which may interest or educate you. Of special note: The Guide to the Dungeons of Doom, for rogue, or the KAME IPv6 implementation notes.
The slides from yesterday’s shell-fu presentation at NYCBUG have been posted.
NYCBUG is having a presentation tomorrow, February 3rd, 18:45, Stone Creek Bar & Lounge at 140 E 27th St. in New York City. The presenter will be Isaac Levy and the title is “shell-fu”. .ike is an energetic speaker and it’s worth your time if you are near enough.
For those of you running DragonFly-current, the already-mentioned library privatization going on means that ports have to be rebuilt. You will want to do it yourself, or wait a little bit before upgrading if you want to install binaries.
John Marino has opened up his new utility for testing: Synth. It’s made for building custom package repositories, similar to poudriere, but much less setup work. If you’ve ever said “I like binary installs, but I want my own build options”, this is for you. The README includes screenshots to show all the things it can do.
Christmas doesn’t stop BSDNow from happening, and this week – along with the normal news summary – has an interview with Trent Thompson about virtualization on FreeBSD. Specifically, iohyve, the new management system.
(Linking directly to the broadcast site instead of the page with the full summary on the BSDNow site, because that summary page isn’t up as of me posting this.)
For those of you that are very bandwidth-constrained, or just impatient, there are xz-compressed images of DragonFly 4.4 available. (see ‘download live image’ area) The mirrors should have them too.
The latest episode interviews Robert N. M. Watson and George V. Neville-Neil for 36 minutes, about teachbsd.org. Also, BSDTalk has been running for 10 years! It’s been long enough I couldn’t remember if it started before the Digest.
The DragonFly installer has been modified to produce disk arrangements that will generally match between UFS and Hammer installs, plus directories where you usually don’t want Hammer history or backups (like /tmp or /usr/obj) are now under /build and null-mounted to where you’d expect, since null-mounting works transparently well on DragonFly. Matthew Dillon has a note explaining the whole thing.
For those of you looking to rent a place to run DragonFly, Nuno Antunes has very helpfully written out his procedure for installing DragonFly on a Digital Ocean ‘droplet’.
As mentioned previously, Sepherosa Ziehau is printing up some DragonFly T-shirts for WeChat users. He’s going to have a few left over, so he is sending them to me to hand to non-China people. If you want one, leave a note saying so in the comments. Here’s the front and back.
You need to provide some way for me to contact you – preferably email, and the size you’d want. (Use the Land’s End Men’s Shirts chart for sizing, because why not.) I’ll only have a few, so no guarantees.
Update: I have more responses than probable shirts at this point – sorry! I’ll get in contact with each of you once the shirts come in and arrange delivery.
It’s tonight at 7 PM, with the details found on the NYCBUG mailing list. RSVP as soon as you can if you are near enough to go – and you should go.
If you are a WeChat user and want a DragonFly BSD shirt, send your Chinese address and mobile number to firstname.lastname@example.org, or scan this image to join the WeChat DragonFly BSD group.
This is exclusive to China right now, as it’s being done by DragonFly developer Sepherosa Ziehau – who, as you might guess by now, is based in China.
BSDNow 119 is up, with even lengthier news summaries than usual, and an interview of Paul Goyette about his testing work with NetBSD.
John Marino has created two custom make variables – .MAKE.DF.OSREL and .MAKE.DF.VERSION. (They return the current DragonFly versioning, if you can’t tell from the name.) Apparently, if you build all 22,000 or so ports together, about 15% of the total time is just awk looking up the system version, and this removes that repeated task.
Matthew Dillon has added two Hammer2 directives – ‘info’ and ‘mountall’. See his commit message for a explanation of each. This predates the 4.4 branch, so it’s available in the current release. The usual caveat applies: Hammer2 is for development only; don’t use this to store data you want to use.
Sharp-eyed users will note that release is happening with version 4.4.1, rather than the 4.4.0 you’d expect. That’s because I tagged 4.4.0, built the images, and then OpenSSL 1.0.1q was released. Rather than make everyone who installs DragonFly need to immediately update, Sascha Wildner brought in the OpenSSL update to the 4.4 branch, and I built 4.4.1 instead.
BSDNow 118 is up, and it has an interview with Mark Heily about relaunchd, along with a number of other BSD news things that I haven’t even read yet because I didn’t expect the episode before today.
DragonFly has historically performed very well with NFS. I don’t have hard numbers to point at (an interesting exercise if someone wanted it), but in any case: DragonFly now can tune up to a much larger iosize, which means better NFS performance. DragonFly <-> DragonFly NFS performance can now max out a GigE link, or with anything else that can handle the larger iosize. That plus additional readahead, also in that commit, means easier netboots.
Since DragonFly 4.4 has been branched, bleeding-edge DragonFly is now at version 4.5. As John Marino detailed in his post, that means pkg on 4.5 systems will look in a new place for downloads. (“dragonfly:4.6:x86:64”, since it always uses even numbers)
To cover for this, set ABI to point at DragonFly 4.4 packages in pkg.conf for now. They’re freshly built and functionally the same, anyway. Once there’s a 4.6 download path, that ABI setting can be removed. Packages for DragonFly-current are available now and probably at the mirrors by the time this posts.
Update: as John Marino pointed out to me, anyone on DragonFly-master who upgrades now will be at version 4.5. This means pkg will get the new (4.5) packages on the next pkg upgrade. That means a mix of old and new packages unless you either reinstall anything (pkg update -f) or hardcode the 4.4 download path until you are ready to switch everything.
So: DragonFly-current users should either hardcode the 4.4 path for now or force an pkg upgrade for everything. DragonFly 4.2-release users are unaffected.
Thanksgiving holiday in the U.S. isn’t slowing down BSDNow, cause there’s a new episode up with Bryan Cantrill talking about the awfulness that is Linux interfaces, along with a bunch of summary news items written out on the page.
I don’t think I linked to this anywhere else: Why did I choose the DragonFlyBSD Operating System? By Siju George, at BSD Magazine.
It’s Thursday and there’s a new BSDNow: Controlling the Transmissions. The interview this week is with Hiren Panchasara, about “improving TCP”, though I haven’t yet listened to it for details. There’s also the normal news roundup.
BSDNow 110 is now available. It’s back to the text summary format, so I can tell you easily that it includes an interview with Benno Rice, about Isilon and their interactions with FreeBSD.
NYCBUG is having “true(1) and false(1), The Classical Code Reading Group of Stockholm, NYC*BUG Mix Tape Edition” happen this Wednesday the 7th. You may remember a similar event at the end of August. This will be led by George Brocklehurst from the original event, with NYCBUG members present. If you missed the previous one, try this out – by all accounts, these code readings are inordinately fun.
The package x11-themes/dragonfly-wallpapers exists, thanks to John Marino, and gives you DragonFly-themed backgrounds in KDE. Or probably any other window manager, if you install it and point your wm at the directory.
Update: John Marino helpfully posted a link to the images. It’s not yet built as a binary, but it’s not exactly time-consuming to build from source.
It has finally happened: There’s no more IPv4 addresses left to allocate, at least for ARIN – and that’s going to affect most people reading this. Ask your ISP for IPv6 access. The next step is being forced to implement either wonky 6to4 mappings, or just plain IPv6 networks.
If you happen to still be running DragonFly 4.0 – that’s two releases ago and not supported – you may be noticing less ports are building. There’s been enough significant changes in DragonFly since that release that it’s reducing the number of buildable ports.
DragonFly 4.0 to 4.2 is not a difficult jump, so jump when you can. The converse of this, of course, is that there’s even more building on 4.2 and DragonFly-current.
BSDNow 106 is up. The interview is with Nigel Williams about, you guessed it, multipath TCP. There’s the normal roundup and not a pun to be seen anywhere. I feel so confused!
If you missed last night’s DNSSEC presentation at CDBUG, here’s the slides.
Why buy ECC RAM? This is a discussion I’ve seen many times. I’ve always heard that without the error checking, you can’t tell if a random bit was flipped by a cosmic particle. That seems like a very remote threat. Over the last week, I went to Science North in Sudbury, Canada, and saw the Diffusion Cloud Chamber. I took a photo myself. Both of those picture represent an instant in time, and each of those squiggles in the chamber in that instant represents some particle zipping through space that miiiiiight scramble your RAM. That’s… a lot more common than I thought.
If you are sure you don’t need to look at your boot menu for very long in DragonFly, you can make it zip by quickly.
A DragonFly machine with a lot of network traffic will have a significant amount of memory consumed by all the running network connections. (as with any system) It’s now possible to adjust the amount of memory set aside for those operations, live. This sort of fine-tuning will only matter if you run an extremely busy machine, but it’s worth it if you do.
DragonFly ships with wpa_supplicant, for setting up WiFi. However, there’s no guarantee it’s the latest version. A solution exists: security/wpa_supplicant in dports. However, this has a chicken-and-egg problem, where you need wpa_supplicant to get online and download the dports version of wpa_supplicant. So, DragonFly still includes wpa_supplicant in the base system, but you should upgrade to the dports version when possible.
There was a newer release of OpenSSL (1.0.1p) last week, so there’s a new revision of the DragonFly release – 4.2.3. There’s little major change other than the security fix for OpenSSL.
Those readers who can count past 2 may notice that there wasn’t a 4.2.2. We went straight from 4.2.1 to 4.2.3. That’s my fault. I screwed up tagging and Git doesn’t like repeated, deleted tags.
Something I’ve wanted for a long time: DragonFly stickers. Or ‘decals’, if you want to sound fancier. Markus Pfeiffer has them set up on Stickermule.
I just created an account there, and apparently I can supply a referral link which gets you and me both a $10 credit, if you use that. It’ll make you sign up, then you’ll probably have to go back in with the direct link for the DragonFly sticker.
BSDNow 096 has the usual new links, even more BSDCan 2015 video links, and an interview with Jun Ebihara about some of NetBSD’s lesser-known architectures.
(I like trying to guess the interview subject from each week’s obscure title; I was going to guess RetroBSD… which would make a good topic to explore.)
There’s a minor update for DragonFly 4.2 – this covers a problem with i915 support, so it’s worth upgrading if you have an Intel video chipset.
If you wanted to try IPFW3 and NAT, nans_nans1 has done the experimentation for you, and wrote down the steps.
I’ve uploaded DragonFly 4.0.6 ISO and .img files. (Does that capitalization make sense?) They should be available at your nearest mirror, or will be shortly. I am still working on the 4.2 release candidate images.
This week’s BSDNow has a talk with DragonFly’s very own Sepherosa Ziehau, about the huge amount of work he’s done on the network stack.
The direct memory access reservation on DragonFly has been set to 128M. It used to be 16, but anyone using a system for more than a text console would want the greater memory reservation. It can be set back to 16M, which is useful probably if you are one of those text console users, or if you have a strangely underpowered video card.
If you are using a DragonFly system with accelerated video, and you have noticed that you can’t return to a text console after exiting xorg – Sascha Wildner/Imre Vadasz have a branch for you to try. Please do so if you have time and are on master; this is the last big item to fix before the next release.
That’s Non Uniform Memory Architecture, and John Baldwin is talking about how it works on FreeBSD, tonight/now, in New York City for NYCBUG. There’s several more events this month with NYCBUG, so look at the announcement for tonight’s location and more dates.
If you were running a version of DragonFly 4.1 (i.e. the master version, not release) built between the 20th and 25th, rebuild. There’s a UFS bug introduced in that short timeframe.
If you are running 4.0.x release or built your version of DragonFly-master outside of that date range – you are unaffected.
If you’re running DragonFly-master and you have an Intel video chipset, Francois Tigeot has an update for you. It brings accelerated Intel video up to match the Linux 3.14 version, adds Broadwell chipset support, and should generally improve performance. He lists how to test right in the message.
DragonFly now has GCC 5.1 release. If you are running DragonFly master (i.e. 4.1), you’ll probably want to both rebuild world and kernel, and update your packages so they all match. There’s already packages built with GCC 5.1, so binary package upgrades can happen quickly. There’s GCC 4.7 packages still available if you aren’t making the jump yet.
If you’re on DragonFly 4.0.x – nothing’s changed.
Here’s some comments from Matthew Dillon on page coloring in DragonFly; a topic that comes up every year for some reason.
The release candidate for GCC5 (5.1.0) is out, and it’s in DragonFly too. It’s not yet switched over to run as the default – that’ll require the release.
The default compiler in DragonFly is going to change over from GCC 4.7 to GCC 5.x very soon, to match the GCC 5.1 release. This means that packages built for DragonFly-master won’t be compatible with the old ones. You will need to reinstall packages when you next ‘pkg install’. John Marino has an extensive writeup detailing what’s needed, and the actual change is some days off.
If you are using DragonFly 4.0.x (the release), this doesn’t affect you at all.
I have had trouble with my daily/weekly periodic reports never making it to my GMail account. Sascha Wildner pointed out to me that periodic.conf has its own answer already:
… and newsyslog is already set to take care of them. There’s more in the periodic.conf man page.
Happy Easter! It means chocolate for me.

John Marino’s written an extensive page about wireless and DragonFly, on dragonflybsd.org.
