From 94bf7c8a626d71a7c206b3e0cdfb43aca305c862 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 5 Apr 2023 15:48:10 +0200 Subject: [PATCH] ACPICA: struct acpi_resource_vendor: Replace 1-element array with flexible array ACPICA commit 446d05d5ea77946b8b3b8d0c638d1a446b18503e Similar to commit 7ba2f3d91a32 ("Replace one-element array with flexible-array"), replace the 1-element array with a proper flexible array member as defined by C99. This allows the code to operate without tripping compile-time and run-time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds, and/or -fstrict-flex-arrays=3). No binary changes appear in the .text nor .data sections. Link: https://github.com/acpica/acpica/commit/446d05d5 Signed-off-by: Bob Moore Signed-off-by: Rafael J.
