https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239894 --- Comment #10 from Kurt Miller <kurt@intricatesoftware.com> --- (In reply to Konstantin Belousov from comment #8) Thank you for writing this. However, it doesn't address the interaction between kernel placed guard pages and pthreads. Consider for example setting security.bsd.stack_guard_page to 513 will call all future pthread_create(2) calls to fail that use default pthread attr (default stack size (512 pages) and guard page (1 page)). An administrator attempting to be more secure will cause most multithreaded applications to fail to work entirely. -- You are receiving this mail because: You are the assignee for the bug.
