This bug arrived with this commit:
b068e758f MINOR: quic: simplify rescheduling for handshake
This commit introduced a bad side effect. Haproxy always replied by an ACK-only
datagram when it received the first client Initial packet. Then it handled
the CRYPTO data insided. And finally, it sent its own CRYPTO data. This broke
the packet coalescing rule whose aim is to optimally build and send as more
as QUIC packets by datagram.
To fix this, simply partially reverts this commit, to make the low level I/O
task return again if some CRYPTO were received. This will delay the
acknowledgement which will be sent with the CRYPTO data from the same
datagram again.
Must be backported to 3.0.
