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
Sudarsan Reddy 951d13d76c TUN-4456: Replaced instances of Tick() with Ticker() in h2mux paths
time.Tick() does not get garbage collected because the channel
underneath never gets deleted and the underlying Ticker can never be
recovered by the garbage collector. We replace this with NewTicker() to
avoid this.

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.

- 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. Unified error handling between h2mux and http2 connections so we log and retry errors the same way, regardless of underlying transport. 2021-01-28 10:38:30 -06:00
Igor Postelnik d503aeaf77 TUN-3118: Changed graceful shutdown to immediately unregister tunnel from the edge, keep the connection open until the edge drops it or grace period expires 2021-01-22 11:14:36 -06:00
Igor Postelnik db0562c7b8 Fixed connection error handling by removing duplicated errors, standardizing on non-pointer error types 2021-01-22 10:58:06 -06:00
Nuno Diegues 2d0b86f2e4 TUN-3777: Fix /ready endpoint for classic tunnels
Classic tunnels flow was triggering an event for RegisteringTunnel for
every connection that was about to be established, and then a Connected
event for every connection established.

However, the RegistreringTunnel event had no connection ID, always
causing it to unset/disconnect the 0th connection making the /ready
endpoint report incorrect numbers for classic tunnels.
