karu.pruun has been trying to get a Macbook’s hybrid graphics card to work in DragonFly. He’s been working on a gmux driver, but it needs a framework like Linux’s switcheroo. If this topic interests you, help him out.
I may have mentioned this in part before, but Matthew Dillon has a brief script to reload pf when an interface IP changes. I’m linking it here in case it’s useful in the future.
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.
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.
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.

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.
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.
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.
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.
