From: "Theo de Raadt" Subject: Re: Fix nested copy(9) for btrace's ustack To: Christian Ludwig Cc: tech@openbsd.org Date: Fri, 07 Mar 2025 09:14:43 -0700 It seems like a huge change in behaviour to have nested operations here. I'm suspicious that it only requires these two changes, and anticipate the entire mechanism can't be moved from singular to nested with just this. That prompts the questions: How did we get here, and is this viable recursion??? I strongly suspect no.
