Subject: Isolate the UTS namespace's domainname and hostname back
From: Pavel Emelyanov <xemul@xxxxxxxxxx>
The commit
commit 7d69a1f4a72b18876c99c697692b78339d491568
Author: Cedric Le Goater <clg@xxxxxxxxxx>
Date: Sun Jul 15 23:40:58 2007 -0700
remove CONFIG_UTS_NS and CONFIG_IPC_NS
accidentally removed the code, that prevented the uts->hostname
and uts->domainname values from being overwritten from another
namespace. In other words, setting hostname/domainname via sysfs
(echo xxx > /proc/sys/kernel/(host|domain)name) cased the new
value to be set in init UTS namespace only.
Return the isolation back.
