cthuang 59f5b0df83 TUN-6530: Implement ICMPv4 proxy
This proxy uses unprivileged datagram-oriented endpoint and is shared by all quic connections

Igor Postelnik 3da1c25471 TUN-6381: Write error data on QUIC stream when we fail to talk to the origin; separate logging for protocol errors vs. origin errors. 2022-06-15 13:06:45 +00:00
Nuno Diegues 475939a77f TUN-6191: Update quic-go to v0.27.1 and with custom patch to allow keep alive period to be configurable
The idle period is set to 5sec.

We now also ping every second since last activity.
This makes the quic.Connection less prone to being closed with
no network activity, since we send multiple pings per idle
period, and thus a single packet loss cannot cause the problem.

Nuno Diegues ed2bac026d TUN-5621: Correctly manage QUIC stream closing
Until this PR, we were naively closing the quic.Stream whenever
the callstack for handling the request (HTTP or TCP) finished.
However, our proxy handler may still be reading or writing from
the quic.Stream at that point, because we return the callstack if
either side finishes, but not necessarily both.

This is a problem for quic-go library because quic.Stream#Close
cannot be called concurrently with quic.Stream#Write

Furthermore, we also noticed that quic.Stream#Close does nothing
to do receiving stream (since, underneath, quic.Stream has 2 streams,
1 for each direction), thus leaking memory, as explained in:
https://github.com/lucas-clemente/quic-go/issues/3322

This PR addresses both problems by wrapping the quic.Stream that
is passed down to the proxying logic and handle all these concerns.

Igor Postelnik 8445b88d3c TUN-5593: Read full packet from UDP connection, even if it exceeds MTU of the transport. When packet length is greater than the MTU of the transport, we will silently drop packets (for now). 2021-12-22 17:18:22 -06:00
