-Subject: [PATCH 083/103] module: Add retpoline tag to VERMAGIC
-
-commit 6cfb521ac0d5b97470883ff9b7facae264b7ab12 upstream.
-
-Add a marker for retpoline to the module VERMAGIC. This catches the case
-when a non RETPOLINE compiled module gets loaded into a retpoline kernel,
-making it insecure.
-
-It doesn't handle the case when retpoline has been runtime disabled. Even
-in this case the match of the retcompile status will be enforced. This
-implies that even with retpoline run time disabled all modules loaded need
-to be recompiled.
