SubjectIssue with clone() and CLONE_NEWUSER as unprivileged user
Date
Hi,

I am trying to use clone() and CLONE_NEWUSER for creating a new user namespace as an unprivileged user. I always get an operation not permitted error. However when I used fork() + unshare() as unprivileged user, I can create the new user namespace just fine.

Is there something obvious that I am missing? My understand is that CLONE_NEWUSER should not require any special capabilities. I tried the sample code from the manpage and also from LWN.net, but both give me the same error.

Regards

Marcel
