bpo-43577: Fix deadlock with SSLContext._msg_callback and sni_callback (GH-24957)#24957
Conversation
OpenSSL copies the internal message callback from SSL_CTX->msg_callback to SSL->msg_callback. SSL_set_SSL_CTX() does not update SSL->msg_callback to use the callback value of the new context. PySSL_set_context() now resets the callback and _PySSL_msg_callback() resets thread state in error path. Signed-off-by: Christian Heimes <christian@python.org>
