+Subject: [PATCH 1/2] Don't send a status_request extension in a
+ CertificateRequest message
+
+If a TLSv1.3 server configured to respond to the status_request extension
+also attempted to send a CertificateRequest then it was incorrectly
+inserting a non zero length status_request extension into that message.
+
+The TLSv1.3 RFC does allow that extension in that message but it must
+always be zero length.
+
+In fact we should not be sending the extension at all in that message
+because we don't support it.
+
+Fixes #9767
