FreeBSD -- hwpmc fails to detach PMCs during exec credential transitions

Problem Description: When a process calls execve2 to execute a setuid or setgid image, hwpmc4 is supposed to detach PMCs owned by unprivileged processes. An inverted check meant that this scenario was not handled properly. Impact: An unprivileged local user who has attached PMCs to a process can...
