It may only happens when there is no data to forward but a last stream frame must be sent with the FIN bit. It is not invalid, but it is useless to send an empty H3 DATA frame in that case. (cherry picked from commit 6697e87ae5e1f569dc87cf690b5ecfc049c4aab0) [ad: This patch was merely considered as an optimization. However, it is in fact mandatory as it fixes a bug on QUIC zero-copy implementation. As such, it must be backported up to 2.9. This bug can happen when iobuf data is null in done_ff, indicating that no data were transferred. Despite this, qcc_send_stream() was always called with data incorrectly incremented to iobuf offset, which is equal to HTTP/3 frame header length. This could cause garbage data emission by QUIC MUX. The most visible effect is that it provokes a BUG_ON() crash when QCS instance is released due to Tx offsets desynchronization. This bug is related to github issue #2678.] Signed-off-by: Amaury Denoyelle <adenoyelle@haproxy.com> |
