I had to fix a reject here: the put_nsproxy(old_ns) has disappeared from
this code.
end result:
int unshare_nsproxy_namespaces(unsigned long unshare_flags,
struct nsproxy **new_nsp, struct fs_struct *new_fs)
{
int err = 0;
if (!(unshare_flags & (CLONE_NEWNS | CLONE_NEWUTS | CLONE_NEWIPC |
CLONE_NEWUSER)))
return 0;
if (!capable(CAP_SYS_ADMIN))
return -EPERM;
*new_nsp = create_new_namespaces(unshare_flags, current,
new_fs ? new_fs : current->fs);
if (IS_ERR(*new_nsp))
err = PTR_ERR(*new_nsp);
goto out;
}
err = ns_container_clone(current);
if (err)
put_nsproxy(*new_nsp);
out:
return err;
}
