If you’ve ever wondered what packages are needed to build a DragonFly release: here they are in one dports metapackage.
DragonFly 5.2.1 tagged
I’ve tagged a x.x.1 release – DragonFly 5.2.1, available now. It includes the recently-mentioned fix for CVE-2018-8897 and some other minor updates. See my email to users@ for the details.

ACPICA update to 20180508 in DragonFly
Sascha Wildner has brought in the last 9 months of ACPICA updates to DragonFly. This may mean better power or motherboard support for your hardware in DragonFly. I always have a hard time pointing directly to ACPICA updates and how they benefit, but looking at the changelog update may help.
BSDNow 246: Properly Coordinated Disclosure
BSDNow 246’s title is talking about CVE-2018-8897, which was (unlike the original Spectre/Meltdown) responsibly disclosed to many different operating system vendors, including the BSDs. As a result, fixes arrived a lot faster… seems like a good idea. No interview in this episode, but as always there’s other topics explored.
ipfw3: highspeed lockless in-kernel NAT
This commit from Bill Yuan says “highspeed lockless in-kernel NAT”, and lists a huge number of changes for ipfw3. How much of a change is it? I don’t know; there isn’t a matching documentation update and I don’t have a way to test.
Your OS and international politics
I like pointing out how political world events push their way into computer updates.
SemiBUG, tonight
SemiBUG‘s having a hands-on server workshop tonight. Go, if you are near, and bring something networked to type on.
GCC 8.0 in DragonFly
Thanks to Rimvydas Jasinskas, GCC 8.0 has been imported into DragonFly. It’s not built by default, so you’ll need to set WORLD_ALTCOMPILER to get it. Rimvydas mentions this is part of a 3-year upgrade cycle.
Note that he went the extra mile and made sure dports could handle it too.

BSDNow 248: ZFS User Conf 2018
Hey, another terse title, and I didn’t even write it! This BSDNow episode talks about the recent ZFS conference. It’s interesting to think there can be a meetup about a file system that isn’t really held to a vendor at this point. There ‘s a number of other articles, too – I’m just a bit late noting it.
CVE-2018-8897 fix in, more Spectre fixes for DragonFly
A recent and new CPU bug, CVE-2018-8897, is fixed in DragonFly. THis applies to both Intel and AMD processors. I’m happy to see that the CERT page lists equal notification timing for a whole lot of operating systems, rather than the few that heard about Spectre/Meltdown early.
Following that topic, Matthew Dillon has “fleshed out” Spectre mitigations, and his commit message details the current state. The sysctl ‘machdep.spectre_mitigation’ will tell you what’s set at any given point.
Update: update.
WOL igb BSD
You can now use Wake On LAN functionality with igb(4) cards in DragonFly.
(I like acronymic titles a little too much, I know.)
BSDNow 244: C is a Lie
I managed to miss posting about BSDNow 244, “C is a Lie”. That provocative title is about how C isn’t a low-level language, not that it doesn’t work. Among other things, this week has new-to-me history about the Larrabee architecture, which I only have heard about indirectly.

systat improvements in DragonFly
systat in DragonFly has gained some new fields when using -pv. Read up on the tool if you have not used it before.
How nice is nice?
Matthew Dillon’s made some changes to the scheduler, with the result that nice(1) is really vigorous now about enforcing priority.
