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.
I like pointing out how political world events push their way into computer updates.
SemiBUG‘s having a hands-on server workshop tonight. Go, if you are near, and bring something networked to type on.
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.

Your rights-oriented hardware project of the week: NeTV2, a Bunnie Huang project. A neat device worth funding on its own, and worth having to show what capabilities are being denied us by law.
This came together very nicely.

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.
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.
You can now use Wake On LAN functionality with igb(4) cards in DragonFly.
(I like acronymic titles a little too much, I know.)
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.
A theme of rebellion this week.

systat in DragonFly has gained some new fields when using -pv. Read up on the tool if you have not used it before.
Matthew Dillon’s made some changes to the scheduler, with the result that nice(1) is really vigorous now about enforcing priority.
Here’s something that doesn’t have an immediate impact now, but will be useful down the road: Francois Tigeot has been working on DRM support in DragonFly, and has been quite successful with Intel video support. His strategy has been to adopt Linux methods where possible, to reduce the amount of support work. The payoff has been excellent, and prompt, accelerated video support in DragonFly. The most recent work is “git: drm: Implement parts of the Linux irq subsystem“, which is going to come in handy for someone, I’m sure.
NYCBUG is having a social (i.e. no presenter) meeting this month – tonight, in fact. Go, talk BSD, drink.
Sascha Wildner has ported FreeBSD’s driver, for LSI Fusion-MPT 3/3.5 SAS controllers. It includes mpr(4), mps(4), and the mpsutil(8)/mprutil(8) management program. It’s in the kernel by default, in fact.
There’s a social meeting for KnoxBUG tonight – go, if you are near.
