This is a conscious choice to disable something that could potentially allow for an entire class of security vulnerabilities. I suppose a decent analogy could be they chose to amputate a damaged foot before it had time to turn gangrenous.
- nbsd4life 8y agoYes, it's probably easier to exploit with hyperthreading, but does disabling hyperthreading stop the exploits? No, it's just an incomplete solution and a minor setback at an enormous cost. OpenBSD does these often, and it looks silly doing it.
- antoinealb 8y agoEnormous cost? If you want to re-enable hyperthreading its just a sysctl away. I mean, OpenBSD is something you are expected to tweak anyway.
