Kees Cook	fe8e353bfd	lkdtm/fortify: Consolidate FORTIFY_SOURCE tests ... The FORTIFY_SOURCE tests were split between bugs.c and fortify.c. Move tests into fortify.c, standardize their naming, add CONFIG hints, and add them to the lkdtm selftests.

Francis Laniel	febebaf366	drivers/misc/lkdtm: add new file in LKDTM to test fortified strscpy ... This new test ensures that fortified strscpy has the same behavior than vanilla strscpy (e.g. returning -E2BIG when src content is truncated). Finally, it generates a crash at runtime because there is a write overflow in destination string.
