From d8e45f2929b94099913eb66c3ebb18b5063e9421 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 6 Mar 2024 15:51:36 -0800 Subject: overflow: Change DEFINE_FLEX to take __counted_by member The norm should be flexible array structures with __counted_by annotations, so DEFINE_FLEX() is updated to expect that. Rename the non-annotated version to DEFINE_RAW_FLEX(), and update the few existing users. Additionally add selftests for the macros. Reviewed-by: Gustavo A. R.
