view src/os/unix/ngx_sunpro_x86.il @ 7672:8d6ac639feac quic
Added support of multiple QUIC packets in single datagram.
- now NEW_CONNECTION_ID frames can be received and parsed
The packet structure is created in ngx_quic_input() and passed
to all handlers (initial, handshake and application data).
The UDP datagram buffer is saved as pkt->raw;
The QUIC packet is stored as pkt->data and pkt->len (instead of pkt->buf)
(pkt->len is adjusted after parsing headers to actual length)
The pkt->pos is removed, pkt->raw->pos is used instead.
