Chip vendors controlling the security of OSes should be more transparent in their selection process. They should maintain a list of OSVs that they maintain embargoed fixes. Then uses could determine if they want to trust the OS or not, or try to lobby to try and get the ISA vendor to support their OS. Is the OS on the list, ok then they may have some chance at fixing things. If not on the list I expect to be vulnerable until the embargo ends. There are MANY more OSes than Microsoft Windows, Apple macOS, a limited number of Linux distros, and sometimes FreeBSD.
In some forums, Bryan Cantrill is crafting a fiction. He is saying the FPU problem (and other problems) were received as a leak. He is not being truthful, inventing a storyline, and has not asked me for the facts. This was discovered by guessing Intel made a mistake. We are doing the best for OpenBSD. Our commit is best effort for our user community when Intel didn’t reply to mails asking for us to be included. But we were not included, there was no reply. End of story. That leaves us to figure things out ourselves. Bryan is just upset we guessed right. It is called science.
