From 74522fea27f8a0695f529089130da64ac98f1761 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 5 Apr 2023 15:50:18 +0200 Subject: ACPICA: actbl2: Replace 1-element arrays with flexible arrays ACPICA commit 44f1af0664599e87bebc3a1260692baa27b2f264 Similar to "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). The sizeof() uses with struct acpi_nfit_flush_address and struct acpi_nfit_smbios have been adjusted to drop the open-coded subtraction of the trailing single element. The result is no binary differences in .text nor .data sections.
