If you’re using qemu and DragonFly, the latest update of ACPICA to version 20160422 may fix some issues introduced in a previous update. (I don’t have a specific bug report to point you at; sorry!)
The DragonFly 4.4.3 point release is out. There’s a commit page listing the changes between 4.4.2 and 4.4.3. Nobody will be surprised that there’s an OpenSSL update in there.
If you want a complete image, it’s available for download at your nearest mirror. If you want to upgrade an existing install:
cd /usr; make src-update
(or src-create-shallow if you don't already have source)
make buildworld && make buildkernel
make installkernel && make installworld
make upgrade
reboot
This is one of those weeks where a bunch of release all tumble together by chance.
- UbuntuBSD Is Looking To Become An Official Ubuntu Flavor. (still confusing)
- PC-BSD 10.3 out; PC-BSD 11 out next. 10.3 was out last week; I missed this link before.
- pfSense 2.3-RELEASE Now Available! (also seen here and here)
- PostgreSQL – Add BSD authentication method. (via)
- BSD and Toshiba Chromebook 2.
- FreeBSD 10.3-Release on AWS. As Colin Percival points out, the last half-dozen releases have been on AWS too.
- Undeadly and HTTPS. (via)
- Penguicon 2016 Lucas Track Schedule. For being called “Penguicon”, there’s a lot of BSD events there.
- DiscoverBSD for 2016/04/11.
- OPNsense 16.1.9 released.
- OPNsense 16.1.10 released.
- Unix’s file durability problem, which leads in comment to disks from the perspective of a file system (McKusick), which I thought I had linked before but maybe not. (via)
- FreeNAS, TrueNAS, and BadLock.
- UbuntuBSD Should Heed Kubuntu’s Cautionary Tale.
Tomohiro Kusumi would like to port Hammer (1) to FreeBSD, as noted in this bug discussion. It’s not even begun to happen, but if you can contribute, please do.
Tomohiro Kusumi has been creating a near-constant stream of bugfixes and cleanups to Hammer for quite some time. I don’t often link to it, because they are incremental improvements and hard to linkblog, so to speak. In an effort to make up for this deficit, I do want to draw attention to his two recent commits: “Make hammer commands print root volume path“, and “Print volume list after volume-add|del“. Small changes, but this is what makes complex systems usable.
If you remember this Baytrail problem, Daniel Bilik has gone and found a fix, as this appears to be a cross-platform bug, and he has patches for DragonFly. If it’s affecting you, you don’t have to wait for the patches to be added in; he’s made them available directly.
Update: it’s committed to DragonFly now.
I keep posting about Sepherosa Ziehau’s work on sustaining extremely high traffic loads in DragonFly. Now I’m posting about a tool to create that load: kq_sendrecv. It creates tens of thousands of TCP connections, without creating a process for each, and uses kqueue, as you might guess from the name. This may be useful if you really want to tax another system.
Do you have a Cherry Trail SoC? For example, a HP x2 210? Imre Vadasz’s recent commit may be useful for you, if you are running DragonFly on this detachable … thing?
Tim Darby is looking for motherboard recommendations. Specifically, mini-ITX with 4 SATA ports and at least one decent network link. Who’s got hardware to recommend? There’s already one set of suggestions.
By the time you read this, I will have already been at my second job for 5 hours.

If you have a Radeon video card in your DragonFly system, and are running bleeding-edge, there’s an update for you. This is a partial sync with Radeon code for Linux 3.18, with no additional notes in the commit but you can always check elsewhere.
unzip has been added to DragonFly, making it present in every BSD but I think OpenBSD.
Imre Vadasz has added the ability to create a UEFI bootloader in DragonFly. Can you use it? I don’t know; I haven’t tried it yet and I can’t tell from the commit.
John Marino has added the starting framework to use clang as the alternate base compiler in DragonFly. Note that it’s not hooked into the build yet. This is the first non-GCC compiler added into DragonFly, so there’s some work yet before you can have an all-clang system. This should replace GCC 4.7, which is the current alternate compiler. GCC 5.0 is the default, if you didn’t know.
Note that clang is present in dports, so it’s already been available for general use, for some time. This framework is for building DragonFly itself.
If you somehow have a device with multiple SD/MMC card slots, you can now access all of them under DragonFly. (Apparently done to make a tablet run DragonFly better, going by IRC conversation)
If you are running bleeding-edge DragonFly, Sepherosa Ziehau has made some networking changes that both reduce CPU usage in high-traffic situations and change some underlying network structures. This means a full buildworld is needed on your next update.
If you’re using DragonFly 4.4.x or older, you are unaffected.
If you find yourself using gpt and disklabel64 for a new disk, and aren’t quite sure what order to type everything in to create a disk slice, why not crib from Tim Darby’s notes? (note that the archive has added some line breaks to it.)
The ‘hammer show’ command can be used to dump the B-Tree structure of a Hammer volume, and CRC errors can be spotted. It’s rare that anyone would need it, but if you do, this dumped information will include file hierarchy information.
If that makes you a bit nervous to repost any of that information when talking about it in public, Tomohiro Kusumi has added an ‘obfuscate’ option to ‘hammer show’ that does just that – it hides path information from the debug output.
Sepherosa Ziehau has continued his quest of making large-scale data transmission on DragonFly effortless; his latest change has cut the kqueue contention rate by two-thirds when dealing with a connection rate of nearly 400,000 connections per second. Note that’s number of connections, without even tracking the bandwidth used by each.
John Marino rearranged how GCC5 handles CPUTYPE settings. If you are specifically setting the target CPU when compiling, his commit will give you an exact list of what to target.
Note that I am not saying another architecture – this is all x86_64. I also don’t recommend doing this unless you have a specific use for it – compiler overoptimizations often create more problems than they fix.
