This bug impacts only the backends. Recent commits have modified quic_rx_pkt_parse() for the QUIC backend to handle the retry token, and version negotiation. This function is called for the quic_conn even when is closing state (so for the quic_conn_closed struct). The quic_conn struct and quic_conn_closed struct share some members thank to the leading QUIC_CONN_COMMON struct. The recent modification impacts some members which do not exist for the quic_connn_closed struct, leading to buffer overflows if modified. For the backends only this patch: 1- silently drops the Retry packet (received/parsed only by backends) 2- silently drops the Initial packets received in closing state This is safe for the Initial packets because in closing state the datagrams are entirely skipped thanks to qc_rx_check_closing() in quic_dgram_parse(). No backport needed because the backend support arrived with the current dev.
