net: Listener crashes on windows #46125

almartino · 2021-05-12T14:57:28Z

What version of Go are you using (`go version`)?

$ go version
go version go1.15.12 windows/amd64

Does this issue reproduce with the latest release?

Yes, test done with:

1.15.12
1.16.3
1.16.4

What operating system and processor architecture are you using (`go env`)?

go env Output

What did you do?

The following program fails when launched directly in the IDE (Goland) and with go run main.go:

package main

import (
	"fmt"
	"log"
	"net"
	"runtime"
)

func main() {
	//handler := rest.RegisterRoutes()
	log.Println("starting server...")
	//if err := http.ListenAndServe("127.0.0.1:8081", handler); err != nil {
	//	log.Fatalf("could not listen and serve: %v", err)
	//}
	fmt.Println(runtime.GOOS)
	lis, err := net.Listen("tcp", "127.0.0.1:9080") // also tried with "tcp", ":9080"
	if err != nil {
		log.Fatal(err)
	}
	defer lis.Close()
	lis.Accept()
}

The same program is ok when launched in debug directly in the IDE(Goland)

The problem occurs also with windows firewall disabled

What did you expect to see?

A working http server / net listener

What did you see instead?

The following exception:

Goland run Output with listen on "127.0.0.1:9080"

This is a low-level crash in the runtime, not likely to be related to the program itself. I suggest disabling any antivirus software you have running.

cc @bradfitz @ianlancetaylor @bufflig

almartino · 2021-05-18T09:42:51Z

We tried the following steps:

uninstall the antivirus software
disable windows defender firewall
disable windows defender real-time protection

Same result.

networkimprov · 2021-05-18T15:07:00Z

On which version of Windows OS does this happen?

Could you try this

set GODEBUG=asyncpreemptoff=1
go run main.go

If that doesn't help, what happens if you close the Conn object returned by Accept?

I'm unable to reproduce this bug on Windows 10.

@almartino I also cannot reproduce this running on current Go tip on Windows 10

Sorry, but I don't have time to debug this.

I do this when installing a network server on Windows, altho I don't think it's the cause of your error:

netsh advfirewall firewall add rule action=allow protocol=tcp enable=yes direction=in ^

Windows 10 Home 2004 (build SO 19041.985)
With set GODEBUG=asyncpreemptoff=1 the error is the same and I can't close the Conn because the program crashes after go run

almartino · 2021-05-19T14:36:34Z

I don't know if this can help, but the same "crash" occurs when I build the executable.

netcrash.zip

alexbrainman · 2021-05-24T08:35:44Z

@almartino what I would do is download original version of Go and try it instead of using IDE.

You can download latest version in a zip file, for example

https://golang.org/dl/go1.16.4.windows-amd64.zip

from

https://golang.org/dl/

Then unzip it somewhere on your system. And then open cmd.exe and try building your program from command line by using go build command, and then try running built program.

To be able to run correct Go version (the one that you unzipped to your disk), you would have to modify your PATH variable before you build your program. You can temporarily change PATH when you open cmd.exe program. Just do this command:

set PATH=c:\directory_where_you_unzipped_go\bin;%PATH%

Just run go version before building the program to make sure you use correct version.

Hi @alexbrainman , we followed your suggested steps, same results.

Did you run go version command. Please show output of it.

Same for go build command. Show output of go build command.

Same for executing your program. Show output of your program.

Thank you.

networkimprov · 2021-05-24T18:09:27Z

Does this happen for a simple "hello world" program with only import "fmt" or is the net.Listen call required to trigger it?

Can you try a similar program in a different language (C#, C, Python, etc) on that machine?

almartino · 2021-05-25T08:10:47Z

Can you try a similar program in a different language (C#, C, Python, etc) on that machine?

the net.Listen call triggers the issue.
We also tried a simple java http server copied from Stackoverflow
(using the same port of the go program)

networkimprov · 2021-05-25T08:29:13Z

And your Java program runs fine?

Did you try the command I suggested in #46125 (comment)? (Requires Admin privs.)

almartino · 2021-05-25T08:56:39Z

And your Java program runs fine?

Did you try the command I suggested in #46125 (comment)? (Requires Admin privs.)

Yes, the java program runs fine, and the "test" handler works when invoked.
Yes, we also tried the command suggested in #46125 (comment), same result.

Additionally, I built the executable from my linux machine with
GOOS=windows GOARCH=amd64 go build -o test.exe ./main.go
And then we executed on the windows machine with no luck... The exception is the same.

We need to see complete stack trace output by test.exe program. Also

set GOTRACEBACK=crash

before you run test.exe so we can see as much detailed stacktrace as possible.

It appears that your go build command works fine on your computer. So it is running the program executable is the problem. Can you try and run your test.exe on another Windows computer?

Thank you.

Sorry I reported a bad info:
The executable built from my linux machine works fine on the windows machine without the exception (accept the connection, then closes the connection and terminates with exit code 0). I also tried the executable on another Windows VM and works without any problems.

Stack trace with set GOTRACEBACK=crash. We used the "system" installed golang version, which is 1.15.12. If you need I can post also the stacktrace with the latest version.

Since the executable built on Linux works, it might help to see a comparison of that with the executable built on Windows.

cc @ianlancetaylor for suggestions on comparing executable files...

alexbrainman · 2021-05-29T08:54:48Z

The executable built from my linux machine works fine on the windows machine without the exception (accept the connection, then closes the connection and terminates with exit code 0).

Good.

I also tried the executable on another Windows VM and works without any problems.

Good.

The stack trace you posted says that your program is running net/http.ListenAndServe, but your original issue #46125 (comment) does not mention net/http.ListenAndServe.

I need complete source code to be able to reproduce your problem. So, please, provide your program source and version of go that use. And do not use go run - just run your program directly. Less things to go wrong. Just do these commands

type main.go
go version
go build -o test.exe
set GOTRACEBACK=crash
test

and provide complete output of these commands.

Thank you.

Alex

Sorry for the delay, I can't investigate more this problem because it is on my colleague's machine.
I'm closing the issue for the moment.
If we find time/situation to do some more testing I'll reopen this.

Thanks for your help.

What version of Go are you using (go version)?

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

What did you do?

What did you expect to see?

What did you see instead?
