Cannot reuse a TLS socket for a HTTP2 session

Version: v14.2.0
Platform: Linux solus 5.6.4-152.current deps: update openssl to 1.0.1j #1 SMP PREEMPT Mon Apr 20 03:18:11 UTC 2020 x86_64 GNU/Linux
Subsystem: http2

What steps will reproduce the bug?

const http2 = require('http2');
const tls = require('tls');

const options = {
  ALPNProtocols: ['h2'],
  host: 'nghttp2.org',
  servername: 'nghttp2.org',
  port: 443,
  settings: {}
};

tls._connect = tls.connect;

/*
tls.connect = (...args) => {
    console.log(...args, args[1].toString());
    return tls._connect(...args);
};
*/

const socket = tls._connect(options, () => {
    console.log('Connected!');
    const session = http2.connect('https://nghttp2.org', {
        createConnection: () => socket
    });

    session.once('remoteSettings', () => {
        console.log('Received remote settings!');
    });
});

How often does it reproduce? Is there a required condition?

Always.

What is the expected behavior?

Connected!
Received remote settings!

What do you see instead?

Connected!

Reference: #16256

The latest code does not reproduce this issue.

What latest code? Do you mean Node.js master branch?

Yes, it may have been fixed in some commit, I didn't reproduce this issue in macOS v10.14.

Indeed, it's fixed on the master branch. Feel free to close the issue, but I'd prefer to keep this open until there's a release that fixes it.

Closing since a fix has been released a while ago.

I ran into this too. I've done some quick tests with the repro above, and:

I can reproduce this in the latest Node 12 (12.18.3)
I can't reproduce this in Node 14.3+. It fails in 14.1 & 14.2, but seems to be fixed from that point onwards. I've specifically tested 14.3, 14.6 and 14.8 (the latest release).

Doing some digging through the changelog, looks like this is the fix: #33209.

That hasn't yet been backported to v12 though. It'd be great if that could be included in the next v12 release to get this fixed, since it causes some big problems for lots of interesting HTTP/2 use cases (like detecting HTTP/2 support during TLS setup, as in https://github.com/szmarczak/http2-wrapper/). I'm not sure where to get started with making that happen, but maybe @addaleax can help?

@szmarczak

Same here, I tested v8.17.0, v10.22.0, v12.18.3, v14.8.0, and only v12.18.3 could reproduce this problem.

@addaleax

This is a really serious bug, could it please be opened up? cc @addaleax

Especially serious since 12 is LTS. My fetch-h2 package, which is relatively well used is totally broken because of this.

@grantila

@grantila Correct me if I’m wrong, but based on the conversation above, backporting #33209 to v12.x would fix this, right? I’ll open a backport PR as suggested over there, there isn’t really anything to do here in the issue anymore. If there’s still problems with backporting, feel free to help with debugging those

#34859

@grantila

@grantila Also, I might be wrong, but if the fix works, then socket.on('secureConnect', () => socket.secureConnecting = false); should be a functional workaround.

@addaleax

I'll be damned, it does work @addaleax, thanks!

fix(node): fixed https connection issue on Node.js 12 and 13
