From 509f8cb2fff927eeb5eb0ebdd410ec6f40430173 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Mon, 20 Jan 2025 06:12:01 -0700 Subject: [PATCH] apparmor: Fix checking address of an array in accum_label_info() clang warns: security/apparmor/label.c:206:15: error: address of array 'new->vec' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] 206 | AA_BUG(!new->vec); | ~~~~~~^~~ The address of this array can never be NULL because it is not at the beginning of a structure. Convert the assertion to check that the new pointer is not NULL.
