+Subject: [PATCH] upstream: Ensure FIDO/PKCS11 libraries contain expected
+ symbols
+
+This checks via nlist(3) that candidate provider libraries contain one
+of the symbols that we will require prior to dlopen(), which can cause
+a number of side effects, including execution of constructors.
+
+Feedback deraadt; ok markus
