From b015d4965ef296b7b31adae9165c5c049cf9026c Mon Sep 17 00:00:00 2001 From: Roman Arutyunyan Date: Wed, 23 Nov 2022 18:50:26 +0400 Subject: [PATCH] QUIC: fixed triggering stream read event (ticket #2409). If a client packet carrying a stream data frame is not acked due to packet loss, the stream data is retransmitted later by client. It's also possible that the retransmitted range is bigger than before due to more stream data being available by then. If the original data was read out by the application, there would be no read event triggered by the retransmitted frame, even though it contains new data. --- src/event/quic/ngx_event_quic_streams.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/event/quic/ngx_event_quic_streams.c b/src/event/quic/ngx_event_quic_streams.c index 78650b04f..73272ff95 100644 --- a/src/event/quic/ngx_event_quic_streams.c +++ b/src/event/quic/ngx_event_quic_streams.c @@ -1147,7 +1147,7 @@ ngx_quic_handle_stream_frame(ngx_connection_t *c, ngx_quic_header_t *pkt, return ngx_quic_close_stream(qs); } - if (f->offset == qs->recv_offset) { + if (f->offset <= qs->recv_offset) { ngx_quic_set_event(qs->connection->read); }
