Add support to ignore unclean TLS shutdowns #503

Closed vanElden closed 4 months ago

vanElden commented 5 months ago

The behaviour with respect to peers that fail to shutdown a TLS connection cleanly has changed in OpenSSL 3. While the correct fix for this is to update the application in question and make sure they send the mandatory close_notify alert on shutdown, this is not always feasible. Therefore add an option to ignore the unexpected EOF that happens in this case.
