04e403e6627d8513d14f3236e52068837eabd2a5 - kunit/overflow: Fix DEFINE_FLEX tests for counted_by

Tue, 04 Mar 2025 18:28:48 +0100

kunit/overflow: Fix DEFINE_FLEX tests for counted_byUnfortunately, __builtin_dynamic_object_size() does not take into accountflexible array sizes, even when they are sized by __counted_by. As aresult, the size tests for the flexible arrays need to be separated toget an accurate check of the compiler's behavior. While at it, fully testsizeof, __struct_size (bdos(..., 0)), and __member_size (bdos(..., 1)).I still think this is a compiler design issue, but there's not much tobe done about it currently beyond adjusting these tests. GCC and Clangagree on this behavior at least. :)Reported-by: "Thomas Weißschuh" 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 List of files: /linux/lib/tests/overflow_kunit.c
