Please answer these questions before submitting your issue. Thanks!

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

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

centos 7 x86_64
What did you do?

build go from source
What did you expect to see?

build pass
What did you see instead?

Are you building as root or some other user?

LK4D4 · 2016-07-07T16:18:51Z

@luohoufu could you check if /proc/self/ns/user exists from your shell?
Also worth to check kernel version and CONFIG_USER_NS in /proc/config.gz or maybe it's somewhere in /boot on centos.

ianlancetaylor · 2016-07-07T17:09:35Z

It may also help to run

go test -c syscall
strace -f ./syscall.test

That should show us exactly which system call is failing with EINVAL.

luohoufu · 2016-07-12T03:57:27Z

@ianlancetaylor
i building go source code as root.

luohoufu · 2016-07-12T04:13:50Z

[root@snails src]# go test -c syscall
[root@snails src]# strace -o /root/go/src/syscall.strace.txt -f /root/go/src/syscall.test
syscall.strace.txt

LK4D4 · 2016-07-12T04:33:33Z

@luohoufu heh, sorry to ask you again, but can you try if unshare -Ur works for you from root and unprivileged user?

luohoufu · 2016-07-12T05:51:04Z

ah,i nerver use unshare,could you tell me how to use it as root user.

LK4D4 · 2016-07-12T14:18:46Z

@luan it's just command line utility. So, I'm doing it's just from my shell.

jessfraz · 2016-07-13T16:15:47Z

I dont think centos 7 has userns enabled out of box? or maybe it's an selinux issue?

jessfraz · 2016-07-13T16:16:25Z

@luohoufu try running

$ unshare --user -- ls -la

luohoufu · 2016-07-14T08:12:45Z

@jfrazelle i can't run with the comman d

Postponing to 1.8, since this only fails when run as root.

luohoufu · 2016-07-22T05:46:25Z

@jfrazelle
when i run you command which you give,i got error is "Invalid parameter",i use ushare -h just want to tell you the unshare usage maybe different with you platform。

jessfraz · 2016-07-25T18:13:32Z

what about unshare -Ur

luohoufu · 2016-07-26T04:53:18Z

@jfrazelle
when i run unshare -Ur i got the same error is "invalid parameter".

jessfraz · 2016-07-26T04:56:56Z

Can you strace it "strace -ff unshare -Ur "

I can repro this in a centos VM so I will fix

jessfraz · 2016-08-17T22:49:11Z

So the USER_NS support in centos 7 seems to be "fubar" (quoted from the first link)
It seems like they broke it, fixed it, then broke it again?

So, out of curiosity (I didn't see it mentioned earlier) you're doing this with 'user_namespace.enable=1' as a boot option to the kernel, correct?

@jperrin thx, now i not continue research this issue,just like @jfrazelle analyse。USER_NS support not well(maybe a bug) in CentOS 7 VM.

I have done some testing with both RHEL 7 and CentOS 7 kernel and I haven't been able to reproduce this issue.

I guess the issue is that RHEL/CentOS 7 don't have the user namespaces enabled by default(and IIRC are not supported). You need to make sure to enable the user_namespace using the kernel boot parameter "user_namespace.enable=1".

To verify the user_namsepaces are enabled use "cat /sys/module/user_namespace/parameters/enable". Double checking the "cat /proc/cmdline" might be good to.

@luohoufu could you provide the output of the above cmds ?

From the discussion, it sounds like this is not a Go problem but a CentOS 7 VM problem. Shall we close it?

Yes it is a CentOS issue, +1 to close
