| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All values are prefixed with name and separated from it using colon. Multiple values are listed without commas in between. Rationale: this greatly simplifies log parsing for analysis.
| * | | | | | | | | | | | | | | | | | | | | | | QUIC: single function for frame debug logging.Vladimir Homutov2020-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function may be called for any initialized frame, both rx and tx. While there, shortened level names.

Acknowledgement Frequency A receiver SHOULD send an ACK frame after receiving at least two ack-eliciting packets.
| * | | | | | | | | | | | | | | | | | | | | | | QUIC: added missing "quic" prefix in debug messages.Vladimir Homutov2020-10-23

Limiting Ranges by Tracking ACK Frames When a packet containing an ACK frame is sent, the largest acknowledged in that frame may be saved. When a packet containing an ACK frame is acknowledged, the receiver can stop acknowledging packets less than or equal to the largest acknowledged in the sent ACK frame.
| * | | | | | | | | | | | | | | | | | | | | | | QUIC: added ACK frame range support.Vladimir Homutov2020-10-20

Up to NGX_QUIC_MAX_RANGES ranges is stored. As a result, instead of separate ack frames, single frame with ranges is sent.

It sets the endpoint key used to generate stateless reset tokens and enables feature. If the endpoint receives short-header packet that can't be matched to existing connection, a stateless reset packet is generated with a proper token. If a valid stateless reset token is found in the incoming packet, the connection is closed. Example configuration: http { quic_stateless_reset_token_key "foo"; ... }

The presence of c->quic pointer is sufficient to enable execution of ngx_quic_close_quic(). The ngx_quic_new_connection() function now returns the allocated quic connection object and the c->quic pointer is set by the caller. If an early error occurs before secrets initialization (i.e. in cases of invalid retry token or nginx exiting), it is still possible to generate an error response by trying to initialize secrets directly in the ngx_quic_send_cc() function. Before the change such early errors failed to send proper connection close message and logged an error. An auxilliary ngx_quic_init_secrets() function is introduced to avoid verbose call to ngx_quic_set_initial_secret() requiring local variable.

The packet processing is centralized in the ngx_quic_process_packet() function which decides if the packet should be accepted, ignored or connection should be closed, depending on the connection state. As a result of refactoring, behavior has changed in some places: - minimal size of Initial packet is now always tested - connection IDs are always tested in existing connections - old keys are discarded on encryption level switch

Redundant checks from ngx_quic_parse_short_header() and ngx_quic_parse_long_header() are removed.
