Backport of #60181 to release/6.0
Fixes#60133
In case of a shutdown by a transport we would throw
QuicOperationAbortedExceptionout ofAcceptStreamAsync, which would wrongly imply that it was our side who initiated the connection shutdown.This is a quick safe fix to make the logic throw
QuicConnectionAbortedExceptioninstead./cc @ManickaP
Customer Impact
Kestrel runs into retry loop in all HTTP/3 end-to-end scenarios with browsers. As a result, it will consume lots of CPU and request response time increases -- basically DoS.
Testing
Manually confirmed it fixes the issue.
Fix also confirmed by the Kestrel team cc @sebastienros
Risk
Very low, S.N.Quic is isolated to HTTP/3 scenarios only. Fix changes only type of the exception thrown, not when and why.
