@mataha: Can you capture an strace of the command that's showing this error ? If you're trying to run a Windows command with interop disabled, this error is expected.

@mataha: Can you capture an strace of the command that's showing this error ? If you're trying to run a Windows command with interop disabled, this error is expected.

It's not a Windows command (though it runs on Windows just fine) - in fact, I can run it without any hiccups if I disable WSLInterop manually:

$ sudo sh -c 'echo -1 >"/proc/sys/fs/binfmt_misc/WSLInterop"'
$ ./make --version

But that defeats the point of interop.enabled = false in the first place; not to mention I have to do that every time I start WSL.

Setting interop.enabled = false won't disable WSLInterop. It seems broken! Contents of/proc/sys/fs/binfmt_misc/ after restart:

zcobol@toto:~$ ls -l /proc/sys/fs/binfmt_misc/
total 0
-rw-r--r-- 1 root root 0 Aug 13 13:58 WSLInterop
-rw-r--r-- 1 root root 0 Aug 13 13:59 WSLInterop-late
--w------- 1 root root 0 Aug 13 13:59 register
-rw-r--r-- 1 root root 0 Aug 13 13:58 status

WSLInterop and WSLInterop-late are present:

zcobol@toto:~$ cat /proc/sys/fs/binfmt_misc/WSLInterop
enabled
interpreter /init
flags: PF
offset 0
magic 4d5a

The file make used for testing has the same magic number as Windows binaries:

zcobol@toto:~$ xxd -l 2 make
00000000: 4d5a                                     MZ

and if running it when WSLInterop is enabled, this is the output:

zcobol@toto:~$ ./make --version
error: APE is running on WIN32 inside WSL. You need to run: sudo sh -c 'echo -1 > /proc/sys/fs/binfmt_misc/WSLInterop'

File info:

zcobol@toto:~$ file make
make: DOS/MBR boot sector; partition 1 : ID=0x7f, active, start-CHS (0x0,0,1), end-CHS (0x3ff,255,63), startsector 0, 4294967295 sectors

The test can be done with a Windows binary, i.e. notepad, using an APE binary is not necessary:

zcobol@toto:~$ notepad.exe
<3>WSL (413) ERROR: UtilAcceptVsock:251: accept4 failed 110

Ok I see. This is unfortunately the same issue as #8203. There seems to be support for binfmt namespacing in recent kernels so we might be able to finally implement this.

/dupe #8203
