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.

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.

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.
