Predrag Punosevac has some notes on how he cleaned up some HAMMER drives and freed up half his disk space.
fetch and timeouts
This will matter most to you if your connection to the Internet is poor: fetch(1) now will time out on data transfers too.
Where the (dports) action is
I mentioned a new committer for DragonFly, Sergey Zigachev, recently. He hasn’t shown in the commit logs for DragonFly directly – cause he’s fixing up dports. I’m mentioning that because the amount of work that goes into dports to keep all those ports working on DragonFly is separate and unseen – but necessary.
New committer: Sergey Zigachev
Welcome Sergey Zigachev, new DragonFly committer who has already committed an amdgpu fix.
A debug difference
If you pay attention to your daily security run emails on your DragonFly system, you may see entries like this:
+nlookup() at nlookup+0x623 0xffffffff806eff13 +kern_rmdir() at kern_rmdir+0x25 0xffffffff80706db5 +sys_rmdir() at sys_rmdir+0x4c 0xffffffff80706f0c +syscall2() at syscall2+0x11e 0xffffffff80bd9f9e
I see it on the machine where I run this Digest, as the caching mechanism adds and deletes files rapidly. Matthew Dillon has placed it behind a sysctl, so your messages log will be a little less noisy by default.
makefs(8) now supports HAMMER2
makefs(8) now supports HAMMER2 on DragonFly, so you can create HAMMER2 file system images, same as a CD image or a DOS disk.
Hetzner cloud and DragonFly
When you are setting up a DragonFly machine on Hetzner, pay attention to this bug report for dhcp setup. The short answer is “use dhcpcd”.
rEFInd design for all the BSDs
Ian Grindley has created a BSD theme for rEFInd that covers all the BSDs – including DragonFly.
Closing credit
Two versions, both right
An interesting thought: since HAMMER2 is intended to be a multi-master file system, it has to figure out – and quickly – which is the most up to date versions of any given file. That means you could have multiple versions of a file existing at the same time until that decision is made. That wouldn’t be visible from a user perspective.
DragonFly 6.2.2 out
Hopefully there’s a new ISO/img on the mirrors for DragonFly 6.2.2 by the time you read this – or you can just update your installation. The changelog is short, because this is a bugfix-level release. Also, don’t forget there’s a new set of binary packages out; update that too if you haven’t.
virtio_console bug report
If you’re interested in having virtio_console on DragonFly, keep an eye on this bug report.
New dports, new point release
There’s a new dports build, and there’s been some updates so a new point release to 6.2.2 for DragonFly is a good idea. The new binary packages are available now with ‘pkg upgrade’, and I’ll work on 6.2.2 over the next few days.
A proper mlockall()
mlockall(2) in DragonFly has been revamped for compatibility with other implementations. This should have no obvious end user impact, other than a bit easier to port stuff. I want to mention it to note the work done.
Interface descriptions on DragonFly
You can now set a description for a network interface on DragonFly. Don’t use ETH0, please.
IPv6 and NAT fix
If you are trying to use both NAT and IPv6 with pf on DragonFly, there was a bug (seen here with FreeBSD) with :0 where it would use link-local addresses. It’s now fixed.
Behavior change for skip in pf
If you are using ‘set skip on …’ in your pf config, it used to match any interface that matched the specified type. It now only matches members of that named group. That may change behavior of your pf rules; check the commit to see what to look for.
sysctl for sysctl
There’s a new sysctl(8) setting, sysctl.debug, which shows you which sysctl nodes are being requested. I am entertained by the pseudo-recursive style of my explanation.
HAMMER2 fixes
There’s some bugfixes for HAMMER2 and the kernel that will probably mean a point release soon.
CI feed on DragonFly site
Headlines from this here Digest show up on dragonflybsd.org, and have for a long time. They are now joined with reports from the continuous integration builds of DragonFly (i.e. Jenkins) DragonFly is automatically rebuilt to test recent commits, and there’s a report for each build on the build machine.
