strlcpy is the one function in this directory's reach that nothing here covers, and a machine directory may override it like any other. Sweep every source and destination alignment pair against sizes 1 to 64, and for each of those every capacity from zero to one past the length. Check the return value, which is the length of src whether or not the copy fit, the truncation point, the content, that a capacity of zero writes nothing at all, and that nothing lands past the terminator. The alignment pairs are the point. An implementation that walks one of the two pointers to a boundary and then copies a register at a time is correct whenever the two agree, so a test that only ever passes matching alignments says nothing about it. The timing half is guarded. perf_gettime() is not a system call, so an application reaches it only where the C library builds its own copy or where the application and the kernel are one image; calling it unconditionally leaves the test unbuildable on a kernel build, which is where the correctness half is still wanted.
