This is an automated email from the git hooks/post-receive script. dgoulet pushed a commit to branch main in repository tor. commit 287c78c5a82f0447af01f3558748f048c9f3d2b2 Author: Micah Elizabeth Scott <beth@torproject.org> AuthorDate: Wed Mar 15 11:52:45 2023 -0700 sandbox: allow stack mmap with prot_none This fixes a failure that was showing up on i386 Debian hosts with sandboxing enabled, now that cpuworker is enabled on clients. We already had allowances for creating threads and creating stacks in the sandbox, but prot_none (probably used for a stack guard) was not allowed so thread creation failed.
