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
