2025-03-04	kunit/overflow: Fix DEFINE_FLEX tests for counted_by	Kees Cook
	Unfortunately, __builtin_dynamic_object_size() does not take into account flexible array sizes, even when they are sized by __counted_by. As a result, the size tests for the flexible arrays need to be separated to get an accurate check of the compiler's behavior. While at it, fully test sizeof, __struct_size (bdos(..., 0)), and __member_size (bdos(..., 1)). I still think this is a compiler design issue, but there's not much to be done about it currently beyond adjusting these tests. GCC and Clang agree on this behavior at least. :) Reported-by: "Thomas Weißschuh" <linux@weissschuh.net> Closes: https://lore.kernel.org/lkml/e1a1531d-6968-4ae8-a3b5-5ea0547ec4b3@t-8ch.de/ Fixes: 9dd5134c6158 ("kunit/overflow: Adjust for __counted_by with DEFINE_RAW_FLEX()") Signed-off-by: Kees Cook <kees@kernel.org>
