| | | | | | | | | | | We actively use only the latest DCID received. And retire only DCIDs requested by the peer to be retired. Also changed the active_conn_id_limit to 2 as the minimum value allowed.

| | | | | | | | | | | | | Though the RXFC was designed for stream flow control, its logic is generic enough to use to control MAX_STREAMS generation. Control of when _we_ can open streams is already done in a bespoke fashion and doesn't use a TXFC, however (see ossl_quic_stream_map_update_state).

* QUIC APL: Defer default XSO creationHugo Landau2023-05-122-25/+127
| | | | | | | | | | | | | | | | QUIC in single-stream mode could be used with a protocol where the server writes first or the client writes first. This determines whether the single stream would be client or server initiated, which affects the stream ID allocated to the stream. We should support both client-sends-first and server-sends-first application protocols. Thus, defer default XSO creation until the point in time at which we know whether a client-first or server-first application protocol is being used. We do this by taking whether SSL_read() or SSL_write() is called first as a cue.

* QUIC APL: Create QUIC CHANNEL up front rather than deferring creationHugo Landau2023-05-121-60/+22
| | | | | | | | | | | | | | | | We switch to instantiating the QUIC_CHANNEL up front at QCSO instantiation time. This creates the QUIC_STREAM_MAP early and makes it easy for us to allocate streams prior to connection initiation. The role (client or server) is determined at QCSO allocation time and cannot be changed. SSL_set_connect/accept_state() are still modelled but their usage must be consistent with the chosen SSL_METHOD which dictates which role is being used.
