Hi,

This series is the rest of the v2 series that was half landed last year,
and finally introduces KUnit runtime testing of the CONFIG_FORTIFY_SOURCE
APIs. Additionally FORTIFY failure messages are improved to give more
context about read/write and sizes.

-Kees

v3
 - rebase (goodbye strlcpy)
 - avoid extra macros for replacing fortify_panic() (nick)
 - generally clean up macro usage
 - avoid build warnings when testing known overflow conditions
v2 https://lore.kernel.org/all/20230407192717.636137-10-keescook@chromium.org/
v1 https://lore.kernel.org/lkml/20230405235832.never.487-kees@kernel.org/
