In Other BSDs for 2016/09/03

A week of travel didn’t get in the way of links! RSS feeds are still fantastic tools for those who know how to use them.

See Michael W. Lucas talk about BSD, several places.

BSDNow 157: ZFS, The “Universal” File-system

I’m a day late posting this because of travel, but: BSDNow 157 has an interview with Richard Yao about ZFS (on Linux?), and more story links. I found the “NetFlix and Fill” article link interesting – those are BSD appliances they are talking about that eat so much of the Internet’s traffic.

Zeroing does nothing

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.

DSA keys disabled on DragonFly

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 update

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.

BSDNow 156: The Fresh BSD Experience

It’s been a very slow news week, but at least there’s a new BSDNow episode: The Fresh BSD Experience. There’s an interview with the FreeBSD Foundation intern, Drew Gurkowski, and a lot of ARM news.

Pulseaudio removed from dports

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.

BSDNow 155: Cabling Up FreeBSD

BSDNow 155: no Allan, but an interview with Myke Geiger about using FreeBSD in an ISP role, and a bunch of news items.

Optimizing your kernel

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!

Buildworld for -current users

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.

BSDNow 154: Myths, Pi’s & Features, oh my!

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.

You probably didn’t use this anyway

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.

IPI benchmarks in DragonFly

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.
