Subject: [PATCH] gcov: use strscpy() instead of strcpy() in init_node()
Date: Mon, 31 Aug 2026 20:19:53 +0530 [thread overview]
Message-ID: <20260831144953.324441-1-hrushirajg23@gmail.com> (raw)
node->name is a flexible array member sized to exactly strlen(name) +
1 bytes at allocation time in new_node(), so this copy can never
actually overflow. Still, prefer the bounded strscpy() over strcpy()
on general principle; pass the same strlen(name) + 1 bound the
allocation used, since sizeof() cannot be applied to a flexible array
member.
No functional change.
