Infinite loop on goroutine with http.ResponseController changes #5671

JeDaYoshi · 2023-08-02T21:35:40Z

Not sure what happened - I was running master on this server for a while, last updated to commit e041962 I believe. I got notified for the Caddy 2.7 release, I re-built it, and now ~~HTTP/3 fails on this specific server by crashing on the first request it gets~~ it seems to be crashing when encode is enabled and the client requests compression.

Caddy version is v2.7.0 h1:ZrAwnBzZ/FBoNw+WBlF2HER8oEs/O7c20ku6nbWFqco=, running on Fedora 38.
Built using Go v1.20.7. (Past working build was on v1.20.6)

systemd[1]: Started caddy.service - Caddy.
caddy[69585]: runtime: goroutine stack exceeds 1000000000-byte limit
caddy[69585]: runtime: sp=0xc0209e0398 stack=[0xc0209e0000, 0xc0409e0000]
caddy[69585]: fatal error: stack overflow
systemd[1]: caddy.service: Main process exited, code=exited, status=2/INVALIDARGUMENT
systemd[1]: caddy.service: Failed with result 'exit-code'.

The info below is now invalid, as it seems to be unrelated.

zsh: terminated  curl3 --http3 -v https://xxx

(Not sure what's up with my curl there - it eats all the RAM it can until the OOM killer terminates it. On Firefox it stays infinitely loading.)

The config isn't something big, either:

xxx {
	import common

	header {
		X-Robots-Tag "none"
		-X-Powered-By
		-Server
	}

	header /api/collect {
		Access-Control-Max-Age "86400"
	}

	reverse_proxy 127.0.0.1:3000
}

common is merely this:

(common) {
	encode {
		zstd
		gzip
	}
}

HTTP/2 seems to be experiencing no crashes, only HTTP/3.

The text was updated successfully, but these errors were encountered:

QUIC_GO_ENABLE_GSO=true is unrelated - crashes without it. Will keep trying to see if I can pinpoint when was the issue introduced/what triggers it.

mholt · 2023-08-02T21:40:06Z

Also noticing some issues now.

Very strange -- was not having issues with testing earlier even today.

mholt · 2023-08-02T21:45:09Z

Pinging @marten-seemann just in case

marten-seemann · 2023-08-02T21:46:56Z

Can you post the stack trace please?

JeDaYoshi · 2023-08-02T21:50:58Z

@marten-seemann It doesn't throw a trace while crashing. I can get it for you; just not sure how at the moment.

Also, I checked out commit e198c60 and the server's back functional. Wondering if cd486c2 could be the cause? (@mholt / @francislavoie)

Keep in mind that I'm not enabling enable_full_duplex on my config.

francislavoie · 2023-08-02T22:01:57Z

Can you try without encode and without header as well to narrow it down?

Sorry about this 😩 I guess we were a bit hasty with that commit.

JeDaYoshi · 2023-08-02T22:14:05Z

Seems like HTTP/3 isn't related in here, and cd486c2 is indeed the culprit. Must have been a coincidence in my case...

@francislavoie Disabling encode fixed it. Works with or without header, just not encode.

francislavoie · 2023-08-02T22:27:13Z

I'm trying to reproduce but I'm having trouble with HTTP/3 locally 😬 why do browsers make it so hard to force HTTP/3 😢 and my usual build of curl https://github.com/yurymuski/curl-http3 doesn't support --compressed. Setting up a VM now to test it instead.

JeDaYoshi · 2023-08-02T22:29:10Z

As mentioned, doesn't seem to be related to HTTP/3 - it's crashing for me on HTTP/2 too, my belief of it being related to HTTP/3 was likely something else doing a request to the server at the same time I was doing one too. It's just merely related to compression.

francislavoie · 2023-08-02T22:29:35Z

Oh, well I can't get it to crash with HTTP/2 either. 🤔

I have encountered the same issue. Here stacktrace:

Ah, @hwilok beat me to it. :)

ueffel · 2023-08-02T22:38:26Z

I'm also getting this. I don't think it has anything to do with h2 or h3.
Its an recursive call here

francislavoie · 2023-08-02T22:41:31Z

Could any/all of you try out a build with #5672? I still can't reproduce it 😩 but I think that should be the fix. Sorry for the trouble! You can build with xcaddy build 9004678

JeDaYoshi · 2023-08-02T22:41:55Z

That was a fast fix - I will try it out and update in here.

JeDaYoshi · 2023-08-02T22:44:41Z

Yep, that seems to be working. No longer crashes for me.

francislavoie · 2023-08-02T22:45:07Z

Thank you! We'll make a v2.7.1 build in the next hour or two.

ueffel · 2023-08-02T22:46:24Z

LGTM too

I happens to me when reverse proxing. Maybe that helps to reproduce?

Edit: The example Caddyfile in #4314 reproduces the stack overflow.

francislavoie · 2023-08-02T23:06:30Z

Thanks @ueffel, you're right that reproduces it. And I confirmed the fix myself as well.

ueffel · 2023-08-02T23:12:01Z

Maybe a test I didn't add for #4314 should be considered 😅

francislavoie · 2023-08-02T23:47:26Z

If you'd like to write a test that'd be great ☺️ I don't have time for it right now.

marten-seemann · 2023-08-03T00:00:28Z

Regarding the patch release, maybe wait on the quic-go patch release (see quic-go/quic-go#4012). Will release tomorrow morning.

mholt · 2023-08-03T00:17:05Z

Ugh, sorry everyone. I am traveling and have a 100 KBps connection. My laptop is not yet configured with my signing key. Give me a little while to get a new tag pushed. In the meantime I'll merge the fix.

@marten-seemann I might still tag ASAP because it's basically broken (somehow tests didn't catch it). Can do a .2 release later though :)

mholt · 2023-08-03T04:32:54Z

Ok, 2.7.1 (and now 2.7.2) are released. Thanks for your patience and sorry for the trouble. In the future I will be more judicious about which changes get included right before a release.

@marten-seemann Sorry for the noise. Thanks for your attentiveness though 😁

Thank you to everyone who helped while I was traveling today.
