I have a number of BSD user group notifications here – please tell me if you have a group and I’m not regularly posting about it.
- NYCBUG meeting on the 4th: Setting up a convenient working environment, with Ivan Ivanov. I’ll post a reminder.
- ChiBUG is meeting on the 17th. RSVP on the mailing list if you are going. I’ll post a reminder.

- FreeBSD on RISC-V as a voting machine test. BSD is common for embedded, high-security hardware – and people tend to not know because it’s embedded, high-security hardware. (via)

For anyone who might need it in the future: some notes on getting Synaptics touchpads and trackpoints working.
Jails on DragonFly now have their own sysctl tree, inherited from defaults. And are no longer MPLOCKed.
The pleasingly-symmetrical BSD Now episode 313 is up now. If you use TLS (and you do), it may be interesting. Also, a link to a Thinkpad and BSD test – also of interest to many.
The radeon driver support on DragonFly now matches Linux 4.7.10. Update and test, especially if you have one of the chipsets mentioned.
First, history: DragonFly has had binaries of dports available for download for quite some time. These were originally built using poudriere, and then using the synth tool put together by John Marino. Synth worked both to build all software in dports, and as a way to test DragonFly’s SMP capability under extreme load.
Matthew Dillon is working on a new version, called dsynth. It is available now but not yet part of the build. He’s been working quickly on it and there’s plenty more commits than what I have linked here. It’s already led to finding more high-load fixes.
Following up on an earlier post, the new servers for DragonFly are in place. The old 40-core machine used for bulk build, monster, is being retired. The power efficiency of the new machines is startling. Incidentally, this is where donations go – infrastructure.
I’m covering all my areas of interest this week, or nearly so.
- Famous computer history quotes, some probably new to you.
- The Bit Player, a movie about Claude Shannon, and a review of it.
- A new Cyriak video, Breakfast. Another attempt to describe fractal infinity, I think. (via)
- D&D plus Shakespeare. (via)
- The Design of Dungeons and Dragons. Talking about the books themselves, not the game. (via)
- Noise Machines, including the nonrepeating sound of a data center. (via)
- Oddball analog smartphones.
- Voyager 1 and 2 are still talking, still active, and possibly the highest-latency communication problem possible. (via)
- Old video game advertisements. (via)
- Absolute scale corrupts absolutely. Lots of great pull quotes in this.
- Tumblr, the Day After. As a counterpoint to the last link, WordPress and Tumblr are two social networks that do not financially depend on either damaging privacy or encouraging outrage.
- Waldenponding, a term new to me.
- Paul Ford Uses This. I’ve linked to his excellent writing before.
- Chesses, variations on chess. Immediately understandable, and playable if you have a second player right there. (via)
Incidentally, my employer, REDCOM, uses FreeBSD as a base for its main product, is deployed in rough areas and in high-security government locations, and is one of the few electronics manufacturers still working entirely in the U.S.. REDCOM also has jobs to fill in New York, where I work. Please, apply if you see a job that interests you – and tell me.
- DistroTest.net, which happens to have runnable online versions of GhostBSD, FreeBSD, HardenedBSD, MidnightBSD, NetBSD, OpenBSD, OPNSense, and DragonFly. (via)
- The VBSDCon schedule (Sept 5-7, very soon!) is up.
- Update webmin/usermin if you have them installed.
- Impact of Tariff Increases. Eventually relevant even if you aren’t a U.S. reader.
- Project Trident 12-U3 and 19.08 now available.
- Valuable News for 2019/08/14 and 2019/08/19.
- Porting wine to amd64 on NetBSD, third evaluation report.
- USBNET: A story of networking and threads that won’t stop pulling.
- Getting the GNU gdbserver to work.
- Fuzzing NetBSD Filesystems via AFL. [Part 2].
- GSoC 2019 Report: Adding NetBSD KNF to clang-format, Part 2.
- Brutal Doom 64 on OpenBSD.
- OpenBSD -stable gets package updates! Release OpenBSD doesn’t normally get packages?
- Blueprint and progress status for mixed environment multilevel backup. Really, the thing to see is a spreadsheet.
- When a hacker tries to infiltrate an OpenBSD machine. Pufferfish reference.
- CFT: CBSD project switched to its own cloud images.
- Instant Workstation.
This week’s BSD Now covers a lot of topics, including linking to a gentle explanation of package management, which surely no reader here needs to have explained? Well, you are covered if so.
Here’s something I haven’t see before: at the time of me typing this, there are commits in DragonFly, FreeBSD, and I assume NetBSD (haven’t found the commit), but the 2019-5612 CVE entry is still shown as reserved and not public. This may change by the time you read this article, of course.
Update: the original source, found by an intrepid reader.
If you have an AM4 motherboard and also can’t EFI boot DragonFly on it, this recent change may fix that for you.
Also, if you are using a Corsair keyboard, this commit may be useful to you.
Matthew Dillon posted an extensive writeup about the hardware changes for dragonflybsd.org; price to performance ratio has been improving so much for multiprocessor machines that we can jump forward both for hosting hardware and for a testbed.
He also mentions his immediate thoughts on what to tackle next, since SMP has been so relentless improved in DragonFly. It resulted in a very long conversational chain as people weighed in with opinions, so I’ve held off posting it until the conversation finished. (I chimed in too.)
Again, way behind cause of being online only irregularly over the last week. There’s still plenty to look at – August is made for Lazy Reading.
This is a somewhat pre-made post coming off a week on the road, so I packed it chock-full.
Roy Marples, the ‘upstream‘ for dhcpcd(8), noticed that DragonFly was working with it as a dhclient/rtsold replacement, but the process wasn’t complete. So … welcome new committer!
DragonFly’s tap(4)/tun(4) devices have been historically precreated – tap0, tap1, tap2, tap3. They are now auto-cloned, which might surprise any software counting on the prior behavior. I don’t know of any specific packages that are affected by this, though. DragonFly version 5.6 is unaffected by this; it’s in -current only.
If you upgrade DragonFly and one of the shared libraries used by pkg gets updated, you can’t run pkg until you get files, but pkg is the program you use to bring in new files. This chicken-and-egg problem is solved with pkg-static, a version of pkg built without shared libraries.
You may have noticed some format flip-flopping between pkg and pkg-static if you had to run it after the most recent DragonFly upgrade; that is fixed. There’s a larger issue of certificate installation identified there; I don’t know a solution to it, but I do want to mention this for next time pkg breaks for someone – pkg-static will work as backup, including to bring in a new version of pkg.
I’m posting this late cause I was traveling when it went up: BSD Now 310 is a nice cross-BSD roundup this week. I might miss the next BSD Now too, so don’t wait for me to link to it.
