tests: fix remaining test failures under _FORTIFY_SOURCE

2026-05-01T02:58:48Z

The getgroups test is a NetBSD tests, so just apply our larger hammer and disable the feature entirely. The audit test can take a more surgical approach and use __ssp_real() appropriately, since it's a local one. PR: 294881 Reviewed by: markj Differential Revision: https://reviews.freebsd.org/D56735

ssp: fix our gets_s implementation under _FORTIFY_SOURCE

2026-05-01T02:58:48Z

Annex K specifies an interface for handling constraint violations from gets_s, but we previously broke this for some classes of get_s misuse. Provide a more nuanced version that tries to dodge errors that would trigger a constraint handler while still providing value. Notably, we don't want to trigger a failure unless the passed-in length reasonably fits within an RSIZE_MAX, because gets_s will immediately call larger lengths bogus and fail.

include/stdbit.h: declare size_t, (u)int_t, and (u)int_least_t

2026-04-20T20:59:54Z

These are required by ISO/IEC 9899:2024 § 7.18.1 ¶ 1 but were forgotten in my initial work. The current approach leaks intptr_t, uintptr_t, intmax_t, and uintmax_t through . This could be avoided using a more complicated approach if desired.

stddef.h: centralize definition of offsetof()

2026-02-19T15:10:32Z

Move to sys/_offsetof.h and use __builtin_offsetof() instead of __offsetof to avoid reintroducing sys/cdefs.h polution in stddef.h. This has the side effect of allowing sys/stddef.h to be included after stddef.h which can happen in compatability headers.
