Extra DragonFly links
These would be ‘In Other BSD’ links, but this isn’t Other BSD – It’s DragonFly:
Towards a HAMMER1 master/slave encrypted setup with LUKS.
Intro, Installation, and Fun with Hammer2.
Building your own DragonFly
Mixed in with the other documentation on the DragonFly website is a “how to build a release” explanation. I use it every time there’s a new DragonFly version. If you were wanting to build a DragonFly ISO/IMG with changes or different preinstalled dports, I’ve added some notes about what’s relevant for non-relea [...]

Half billion tries for a HAMMER2 bug

Errata patches for x86 floating-point units have been released for OpenBSD 6.3.
Intel CPUs speculatively access FPU registers even when the FPU is disabled,
so data (including AES keys) from previous contexts could be discovered if
using the lazy-save approach.
Binary updates for the amd64 platform are available via the syspatch utility.
So [...]
