Subject: Stable release 4.4.286 broken for ARM64 with CONFIG_CC_STACKPROTECTOR=y
Date: Wed, 6 Oct 2021 21:20:42 +0000 [thread overview]
Message-ID: <DM5PR11MB001226B8D03B8CC8FA093AC6DDB09@DM5PR11MB0012.namprd11.prod.outlook.com> (raw)
Hello,
latest stable release 4.4.286 does not build for me on ARM64 with
CONFIG_CC_STACKPROTECTOR=y.
The offending commit
commit 69e450b170995e8a4e3eb94fb14c822553124870
Author: Dan Li <ashimida@linux.alibaba.com>

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

arch: Introduce post-init read-only memory
