https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=209233 Bug ID: 209233 Summary: [patch] pthread_suspend_all_np races with check_suspend Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Some People Priority: --- Component: threads Assignee: freebsd-threads@FreeBSD.org Reporter: le277@cam.ac.uk Keywords: patch Created attachment 169926 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=169926&action=edit Patch to fix race Currently the suspend all implementation in libthr only sets the NEED_SUSPEND flag if a thread does not have the SUSPENDED flag set. However, that thread may be in the process of resuming, and so its NEED_SUSPEND flag should always be set if we wish a thread to stay suspended, even if already has the SUSPENDED flag set. -- You are receiving this mail because: You are the assignee for the bug.home | help
