cthuang 3449ea35f2 TUN-6791: Calculate ICMPv6 checksum 2022-09-22 15:18:53 +00:00
Sudarsan Reddy 7f487c2651 TUN-6775: Add middleware.Handler verification to ProxyHTTP
ProxyHTTP now processes middleware Handler before executing the request.
A chain of handlers is now executed and appropriate response status
codes are sent.

Sudarsan Reddy 9bb7628fbc TUN-6772: Add a JWT Validator as an ingress verifier
This adds a new verifier interface that can be attached to ingress.Rule.
This would act as a middleware layer that gets executed at the start of
proxy.ProxyHTTP.

A jwt validator implementation for this verifier is also provided. The
validator downloads the public key from the access teams endpoint and
uses it to verify the JWT sent to cloudflared with the audtag (clientID)
information provided in the config.

Sudarsan Reddy eb36716ba4 TUN-6774: Validate OriginRequest.Access to add Ingress.Middleware
We take advantage of the JWTValidator middleware and attach it to an
ingress rule based on Access configurations. We attach the Validator
directly to the ingress rules because we want to take advantage of
caching and token revert/handling that comes with go-oidc.

Sudarsan Reddy 91eba53035 TUN-6639: Validate cyclic ingress configuration
This reverts commit d4d9a43dd7.

We revert this change because the value this configuration addition
brings is small (it only stops an explicit cyclic configuration versus
not accounting for local hosts and ip based cycles amongst other things)
whilst the potential inconvenience it may cause is high (for example,
someone had a cyclic configuration as an ingress rule that they weren't
even using).

Sudarsan Reddy d4d9a43dd7 TUN-6639: Validate cyclic ingress configuration
It is currently possible to set cloudflared to proxy to the hostname
that traffic is ingressing from as an origin service. This change checks
for this configuration error and prompts a change.

Igor Postelnik f2339a7244 TUN-6380: Enforce connect and keep-alive timeouts for TCP connections in both WARP routing and websocket based TCP proxy.
For WARP routing the defaults for these new settings are 5 seconds for connect timeout and 30 seconds for keep-alive timeout. These values can be configured either remotely or locally. Local config lives under "warp-routing" section in config.yaml.

For websocket-based proxy, the defaults come from originConfig settings (either global or per-service) and use the same defaults as HTTP proxying.

Nuno Diegues 5e6f606f4e TUN-6293: Update yaml v3 to latest hotfix
This addresses https://security.snyk.io/vuln/SNYK-GOLANG-GOPKGINYAMLV3-2841557
by updating yaml v3 to latest version.

It also stops using yaml v2 directly (we were using both v2 and v3 mixed).
We still rely on yaml v2 indirectly, via urfave cli, though.

Note that the security vulnerability does not affect v2.

Nuno Diegues 0ab6867ae5 TUN-4947: Use http when talking to Unix sockets origins
Right now the proxying of cloudflared -> unix socket is a bit of
a no man's land, where we do not have the ability to specify the
actual protocol since the user just configures "unix:/path/"

In practice, we proxy using an HTTP client.
But it could be that the origin expects HTTP or HTTPS. However,
we have no way of knowing.

So how are we proxying to it? We are configuring the http.Request
in ways that depend on the transport and edge implementation, and
it so happens that for h2mux and http2 we are using a http.Request
whose Scheme is HTTP, whereas for quic we are generating a http.Request
whose scheme is HTTPS.

Since it does not make sense to have different behaviours depending
on the transport, we are making a (hopefully temporary) change so
that proxied requests to Unix sockets are systematically HTTP.

In practice we should do https://github.com/cloudflare/cloudflared/issues/502
to make this configurable.

João Oliveirinha 7e47667b08 TUN-5481: Create abstraction for Origin UDP Connection
Creates an abstraction over UDP Conn for origin "connection" which can
be useful for future support of complex protocols that may require
changing ports during protocol negotiation (eg. SIP, TFTP)
In addition, it removes a dependency from ingress on connection package.
