The offending commit commit 69e450b170995e8a4e3eb94fb14c822553124870 Author: Dan Li <ashimida@xxxxxxxxxxxxxxxxx> Date: Tue Sep 14 11:44:02 2021 arm64: Mark __stack_chk_guard as __ro_after_init The 4.4.y kernel does not have the ro_after_init section defined at all, stable kernel 4.9.y is the first to have it. I do not have an overview of this feature, but it appears to have started with commit commit c74ba8b3480da6ddaea17df2263ec09b869ac496 Author: Kees Cook <keescook@xxxxxxxxxxxx> Date: Wed Feb 17 23:41:15 2016 arch: Introduce post-init read-only memory -- Best regards, Hans-Christian Noren Egtvedt.
