Regarding the patch, I will check with the author.

As to the functionality we indeed ignored all posth-handshake messages, but now when TLS_HANDSHAKE messages are received they are feeded to gnutls for processing via [gnutls_handshake_write()](https://www.gnutls.org/manual/gnutls.html#index-gnutls_005fhandshake_005fwrite). GnuTLS derives new keys and sends them to kernel via [_gnutls_ktls_set_keys()](https://gitlab.com/gnutls/gnutls/-/blob/master/lib/system/ktls.c#L83) then sends the key_update message to the peer.
