Review needed!

  • switch to upstream quic-go
  • drop go 1.18 as quic-go no longer supports it
  • update import paths

lgtm. Didn't check vendor changes are correct.

As I have mentioned before in the PR, we can't accept these changes without the following commit either applied to a new fork of quic-go or ideally merged upstream to quic-go: Make max datagram frame size configurable: chungthuang/quic-go/commit/40b85c87

More specifically, you removed this line which we rely on: https://github.com/cloudflare/cloudflared/pull/945/files#diff-d22dda08284a6d0f67f2db14172dfa24bc8afd69bf40d47b7aa5e3ebede00cd5L603

We have not had the time yet to tackle this change since there was some API surface changes happening in quic-go that don't make the application of the commit just a rebase like it was previously.

I don't think that's necessary anymore. It was meant to fix the problem at quic-go/quic-go#3273, and it's resolved upsteam: quic-go/quic-go#3276. What do you think?

It was not meant to address the Windows MTU discoverability issue, that change was needed to set the max datagram size as defined in https://www.rfc-editor.org/rfc/rfc9221.html. It looks like there have been some changes in quic-go that make it easier to coordinate this change, but we still require this change to set the MaxDatagramFrameSize to 1350: https://github.com/cloudflare/cloudflared/blob/master/quic/param_unix.go#L6

I have started with a baseline of changes to add this to quic-go, but I haven't had the time yet to test it completely: DevinCarr/quic-go@d1f4eda. Once this change is added to either a fork or merged upstream, we can evaluate the quic-go upgrade and go 1.20 changes to cloudflared.

I have merged in the quic-go changes (9426b60) that should unblock the rest of this PR if you wish to restart it with just upgrading to go 1.20. Otherwise, I can close this and do it in the next couple of days.

We are still not on upstream quic-go but a fork with our applied patch. We have also started a conversation to see if we can get our patch changes into upstream quic-go as the changes should be RFC compliant for quic datagrams. quic-go/quic-go#3300

Thanks for your initial efforts to get this started!

- update all dependencies
- switch to devincarr/quic-go
- drop go 1.18 as quic-go no longer supports it

To support go 1.20 and upcoming go 1.21 (currently at rc4) bump to 0.37.1:

Suggested change
github.com/quic-go/quic-go v0.34.0
github.com/quic-go/quic-go v0.37.1

Of course some additional changes may be needed in addition to the usual go mod tidy and go mod vendor.

See https://github.com/quic-go/quic-go/releases/tag/v0.37.1 and https://github.com/quic-go/quic-go/releases/tag/v0.37.0

We are going to address this internally because it requires some more careful details due to QUIC-GO.
As of now we already compile with go1.20, and the next step will be 1.21 which as stated will require a little more effort.

For now, we will close this.
