Subject: Isolate the UTS namespace's domainname and hostname back
X-Git-Tag: v2.6.24-rc4~54
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=32df81cbd5b41d281cc3d7e7ff6a98ac6201e197;p=pandora-kernel.git

Isolate the UTS namespace's domainname and hostname back

Commit 7d69a1f4a72b18876c99c697692b78339d491568 ("remove CONFIG_UTS_NS
and CONFIG_IPC_NS") by Cedric Le Goater 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.
