Static buffers are used instead in functions where decryption takes place.
The pkt->plaintext points to the beginning of a static buffer.
The pkt->payload.data points to decrypted data actual start.
+ ngx_quic_encrypt():
- no longer accepts pool as argument
- pkt is 1st arg
- payload is passed as pkt->payload
- performs encryption to the specified static buffer
+ ngx_quic_create_long/short_packet() functions:
- single buffer for everything, allocated by caller
- buffer layout is: [ ad | payload | TAG ]
the result is in the beginning of buffer with proper length
- nonce is calculated on stack
- log is passed explicitly, pkt is 1st arg
- no more allocations inside
+ ngx_quic_create_long_header():
- args changed: no need to pass str_t
+ added ngx_quic_create_short_header()
+ Client-related errors (i.e. parsing) are done at INFO level
+ c->log->action is updated through the process of receiving, parsing.
handling packet/payload and generating frames/output.
For ngx_http_process_request() part to work, this required to set both
r->http_connection->ssl and c->ssl on a QUIC stream. To avoid damaging
global SSL object, ngx_ssl_shutdown() is managed to ignore QUIC streams.
+ ngx_quic_init_ssl_methods() is no longer there, we setup methods on SSL
connection directly.
+ the handshake_handler is actually a generic quic input handler
+ updated c->log->action and debug to reflect changes and be more informative
+ c->quic is always set in ngx_quic_input()
+ the quic connection state is set by the results of SSL_do_handshake();
note:
+ parameters are available in SSL connection since they are obtained by ssl
stack

During connection establishment, both endpoints make authenticated
declarations of their transport parameters. These declarations are
made unilaterally by each endpoint.
and really, we send our parameters before we read client's.
no handling of incoming parameters is made by this patch.
- integer parameters can be configured using the following directives:
quic_max_idle_timeout
quic_max_ack_delay
quic_max_packet_size
quic_initial_max_data
quic_initial_max_stream_data_bidi_local
quic_initial_max_stream_data_bidi_remote
quic_initial_max_stream_data_uni
quic_initial_max_streams_bidi
quic_initial_max_streams_uni
quic_ack_delay_exponent
quic_active_migration
quic_active_connection_id_limit
- only following parameters are actually sent:
active_connection_id_limit
initial_max_streams_uni
initial_max_streams_bidi
initial_max_stream_data_bidi_local
initial_max_stream_data_bidi_remote
initial_max_stream_data_uni
(other parameters are to be added into ngx_quic_create_transport_params()
function as needed, should be easy now)
- draft 24 and draft 27 are now supported
(at compile-time using quic_version macro)
