Improve logging and error messages when mismatch between client and server protocol/TLS

[JamesNK]

My experience with gRPC is that it is very common to run into trouble establishing a connection between the client and the server because of incorrect protocol/TLS.

The logging and error messages that Kestrel/IIS provides should do as much as possible to to help developers fix their own mistakes. Also I would like to make sure that we're sending the best response to clients in these situations to help the client give the developer a good understanding of what is wrong.

Common problem situations:

1. Client (HTTP/2 with and without TLS) calling HTTP/1 only port
2. Client (HTTP/1 with and without TLS) calling HTTP/2 only port
3. Client (HTTP/2 without TLS) calling HTTP/1 and HTTP/2 port (will fail because no negotiation and default to 1.1)
4. Client (no TLS) calling TLS port
5. Client (TLS) calling no TLS port

[Tratcher]

Do you have examples for the client and server errors you see for each of these? Expect different client errors in browsers vs libraries (HttpClient).

1 Client (HTTP/2 with and without TLS) calling HTTP/1 only port

With TLS:
The client should get an ALPN error. The server will only see the client disconnect with an incomplete handshake, it can't tell why.

Without TLS:
It would require sniffing the "PRI *" preamble in the HTTP/1 parser. Cost: Small

2 Client (HTTP/1 with and without TLS) calling HTTP/2 only port

Similar to case 1. We should already be logging a decent error for the non-TLS scenario when the preamble doesn't match, but we may not be sending it to the client.

3 Client (HTTP/2 without TLS) calling HTTP/1 and HTTP/2 port (will fail because no negotiation and default to 1.1)

There's no such thing as a HTTP/1 + HTTP/2 port without TLS (Upgrades asside). The two can only be combine with TLS and ALPN. In practice this is the same as case 1 above.

4 Client (no TLS) calling TLS port

Would require intercepting the TLS handshake. Cost: Medium.

5 Client (TLS) calling no TLS port

I thought we already added a server log for this in 3.0? Sending an error to the client here would be hard, we'd have to emulate TLS. A TLS fatal Alert maybe?

[Tratcher]

Since the cause, solution, and priority for each of these is so different we'll want to break out any we decide to address into individual issues.

[JamesNK]

I'll investigate. Will update this issue and then we can create more targeted issues.

Nice permutation. You're not logging the client errors?

Next would be grouping by error message.

I'm doing the same exercise with HttpClient on dotnet/corefx 😄

@JamesNK Can we recognize that the handshake failed because the client is not using TLS?

@JamesNK Can we recognize that HTTP/1.1 is being used on a HTTP/2 endpoint? Also, it seems odd that HTTP/2 + TLS generates the same message on a HTTP/2 + no TLS endpoint.

@JamesNK I don't see how this could work, but there is no error on the server. Logging shows the connection being reset then eventually closed. Can we do anything here?

Edit: Is this silently downgrading to 1.1? Could the server log that?

@JamesNK The stopped and closing logs here might be coming from other HttpClients being closed. I should probably have disposed them after each scenario 😄

Is there proposed action here? I think this seems good and I'm all for sniffing different protocol stuff to produce better errors, but we need to break it down into specific actions we want to take.

Action: Let's build the matrix and try to produce useful errors for all the combinations in the logs at least. We may be able to do things like return 400 errors or TLS alerts, but I don't want to make the scope of this too big :).

I posed some questions when I grouped all the errors together. The action is for a server expert to figure out whether these errors could be improved.

I don't think improving them is worth spending a lot of resources on, but it would be good to figure out if there are any quick wins to improve the debugging experience.
