This patch removes <mux_state> field from quic_conn structure. The purpose of this field was to indicate if MUX layer above quic_conn is not yet initialized, active, or already released. It became tedious to properly set it as initialization order of the various quic_conn/conn/MUX layers now differ between the frontend and backend sides, and also depending if 0-RTT is used or not. Recently, a new change introduced in connect_server() will allow to initialize QUIC MUX earlier if ALPN is cached on the server structure. This had another level of complexity. Thus, this patch removes <mux_state> field completely. Instead, a new flag QUIC_FL_CONN_XPRT_CLOSED is defined. It is set at a single place only on close XPRT callback invokation. It can be mixed with the new utility functions qc_wait_for_conn()/qc_is_conn_ready() to determine the status of conn/MUX layers now without an extra quic_conn field. |
