I don't suppose that I have any #bsd #unix #foss #infosec friends out there willing to signal boost, by chance?

AKA canadianbryan. I like tinkering with #OpenBSD and occasionally other Unix-like systems. In other words, not a MCP. He/Him. 🍕💻🇨🇦
Mark Kettenis has brought over the generic binary codepatching infrastructure to the #OpenBSD/arm64 kernel, and is using it to NOP out costly mitigations for microarchitectural vulnerabilities on CPUs that are not vulnerable.
The codepatch code is put in a separate section which gets unmapped after boot, making it unavailable for use in ROP attacks. 
The commit addresses CVE-2025-10263 too, I guess.
Hope my fellow #OpenBSD developers are having an amazing time this week at the #g2k26 #hackathon in Kloosterburen (The Netherlands)!

#OpenBSD -current has cranked the kernel virtual address space (VM_MAX_KERNEL_ADDRESS) on amd64 from 4GB to 512GB (one PML4 entry with 4-level paging).

Good news for people with AMD Radeon GPUs with lots of VRAM.
Happy Father's Day to all the fathers out there that don't ghost their children throughout their entire adult life.
Stefan SperlingI could really use a few extra pizzas this month, friends. 
Hope all my *BSD friends visiting Canada for #BSDCan this week have fun in Ottawa! 
... but not too much fun. 
Years ago, there was a BSD search page at google dot com/bsd (long gone), amusingly, the custom logo is still hosted on Google's servers.
If any of my work on #OpenBSD, or my highlight posts here (or elsewhere) has been helpful in the past, a small recurring monthly donation would be extremely appreciated.
