This tests what FreeBSD-SA-26:56.hwpmc fixed. exec_setgid_drops_pmc asserts the kernel takes a process-mode PMC away when its target execs a set-gid program its owner is not entitled to trace. exec_setuid_no_double_unlink lets the target exec a set-uid program; the teardown must unlink the process descriptor exactly once, and completing at all is the assertion. Both need an unprivileged owner and must not drop privileges themselves, since p_candebug() would then refuse the target to its own owner; they ask for require.user instead.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
