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.

Sudarsan Reddy d678584d89 TUN-4655: ingress.StreamBasedProxy.EstablishConnection takes dest input
This change extracts the need for EstablishConnection to know about a
request's entire context. It also removes the concern of populating the
http.Response from EstablishConnection's responsibilities.

Sudarsan Reddy f1b57526b3 TUN-4626: Proxy non-stream based origin websockets with http Roundtrip.
Reuses HTTPProxy's Roundtrip method to directly proxy websockets from
eyeball clients (determined by websocket type and ingress not being
connection oriented , i.e. Not ssh or smb for example) to proxy
websocket traffic.

Igor Postelnik 3ad99b241c TUN-4168: Transparently proxy websocket connections using stdlib HTTP client instead of gorilla/websocket; move websocket client code into carrier package since it's only used by access subcommands now (#345). 2021-04-07 16:25:46 +00:00
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.

Igor Postelnik da4d0b2bae TUN-4067: Reformat code for consistent import order, grouping, and fix formatting. Added goimports target to the Makefile to make this easier in the future. 2021-03-24 10:53:29 -05:00
Lee Valentine 206523344f TUN-4017: Add support for using cloudflared as a full socks proxy.
To use cloudflared as a socks proxy, add an ingress on the server
side with your desired rules. Rules are matched in the order they
are added.  If there are no rules, it is an implicit allow.  If
there are rules, but no rule matches match, the connection is denied.

ingress:
  - hostname: socks.example.com
    service: socks-proxy
    originRequest:
      ipRules:
        - prefix: 1.1.1.1/24
          ports: [80, 443]
          allow: true
        - prefix: 0.0.0.0/0
          allow: false

On the client, run using tcp mode:
cloudflared access tcp --hostname socks.example.com --url 127.0.0.1:8080

Set your socks proxy as 127.0.0.1:8080 and you will now be proxying
all connections to the remote machine.

- 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
