6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kees Cook <keescook@xxxxxxxxxxxx> commit 3e00f5802fabf2f504070a591b14b648523ede13 upstream. We continue to see false positives from -Warray-bounds even in GCC 10, which is getting reported in a few places[1] still: security/security.c:811:2: warning: `memcpy' offset 32 is out of the bounds [0, 0] [-Warray-bounds] Lower the GCC version check from 11 to 10.
