Origintunneld has been observed to continue sending reply packets to the first incoming connection it received, even if a newer connection is observed to be sending the requests.
OTD uses the funnel library from cloudflared, which is why the changes are here.
In theory, cloudflared has the same type of bug where a ping session switching between quic connections will continue sending replies to the first connection. This bug has not been tested or confirmed though, but this PR will fix if it exists.
Remove send and return methods from Funnel interface. Users of Funnel can provide their own send and return methods without wrapper to comply with the interface.
Move packet router to ingress package to avoid circular dependency
ProxyHTTP now processes middleware Handler before executing the request.
A chain of handlers is now executed and appropriate response status
codes are sent.
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.
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.

A funnel is an abstraction for 1 source to many destinations.
As part of this refactoring, shared logic between Darwin and Linux are moved into icmp_posix
