Nuno Diegues 1086d5ede5 TUN-5204: Unregister QUIC transports on disconnect
This adds various bug fixes when investigating why QUIC transports were
not being unregistered when they should (and only when the graceful shutdown
started).

Most of these bug fixes are making the QUIC transport implementation closer
to its HTTP2 counterpart:
 - ServeControlStream is now a blocking function (it's up to the transport to handle that)
 - QUIC transport then handles the control plane as part of its Serve, thus waiting for it on shutdown
 - QUIC transport now returns "non recoverable" for connections with similar semantics to HTTP2 and H2mux
 - QUIC transport no longer has a loop around its Serve logic that retries connections on its own (that logic is upstream)

Nuno Diegues e35f744b36 TUN-5393: Content-length is no longer a control header for non-h2mux transports
- Refactors some h2mux specific logic from connection/header.go to connection/h2mux_header.go
 - Do the same for the unit tests
 - Add a non-h2mux "is control response header" function (we don't need one for the request flow)
 - In that new function, do not consider "content-length" as a control header
 - Use that function in the non-h2mux flow for response (and it will be used also in origintunneld)

Sudarsan Reddy bccf4a63dc UN-5213: Increase MaxStreams value for QUIC transport
The default max streams value of 100 is rather small when subject to
high load in terms of connecting QUIC with streams faster than it can
create new ones. This high value allows for more throughput.

Sudarsan Reddy 27e1277a3b TUN-5142: Add asynchronous servecontrolstream for QUIC
ServeControlStream accidentally became non-blocking in the last quic
change causing stream to not be returned until a SIGTERM was received.
This change makes ServeControlStream be non-blocking for QUIC streams.

Sudarsan Reddy 8f3526289a TUN-4701: Split Proxy into ProxyHTTP and ProxyTCP
http.Request now is only used by ProxyHTTP and not required if the
proxying is TCP. The dest conversion is handled by the transport layer.

Nuno Diegues b06fe0fc5f TUN-4571: Fix proxying to unix sockets when using HTTP2 transport to Cloudflare Edge 2021-06-21 11:43:14 +01:00
Igor Postelnik 8ca0d86c85 TUN-3863: Consolidate header handling logic in the connection package; move headers definitions from h2mux to packages that manage them; cleanup header conversions
All header transformation code from h2mux has been consolidated in the connection package since it's used by both h2mux and http2 logic.
Exported headers used by proxying between edge and cloudflared so then can be shared by tunnel service on the edge.
Moved access-related headers to corresponding packages that have the code that sets/uses these headers.
Removed tunnel hostname tracking from h2mux since it wasn't used by anything. We will continue to set the tunnel hostname header from the edge for backward compatibilty, but it's no longer used by cloudflared.
Move bastion-related logic into carrier package, untangled dependencies between carrier, origin, and websocket packages.

cthuang e2262085e5 TUN-3617: Separate service from client, and implement different client for http vs. tcp origins
- extracted ResponseWriter from proxyConnection
 - added bastion tests over websocket
 - removed HTTPResp()
 - added some docstrings
 - Renamed some ingress clients as proxies
 - renamed instances of client to proxy in connection and origin
 - Stream no longer takes a context and logger.Service

Igor Postelnik cf562ef8c8 TUN-3635: Send event when unregistering tunnel for gracful shutdown so /ready endpoint reports down status befoe connections finish handling pending requests. 2021-02-08 15:38:42 +00:00
Igor Postelnik 0b16a473da TUN-3869: Improve reliability of graceful shutdown.
- Don't rely on edge to close connection on graceful shutdown in h2mux, start muxer shutdown from cloudflared.
- Don't retry failed connections after graceful shutdown has started.
- After graceful shutdown channel is closed we stop waiting for retry timer and don't try to restart tunnel loop.
- Use readonly channel for graceful shutdown in functions that only consume the signal

Igor Postelnik a945518404 TUN-3811: Better error reporting on http2 connection termination. Registration errors from control loop are now propagated out of the connection server code.
