[PATCH] XSM/policy: Allow the source domain access to settime and setdomainhandle domctls while creating domain.

[PATCH] XSM/policy: Allow the source domain access to settime and setdomainhandle domctls while creating domain.

[Anshul]

From: Anshul Makkar <anshul.makkar@citrix.com>

This patch resolves the following permission denied scenarios while creating
new domU :
avc:  denied  { setdomainhandle } for domid=0 target=1
scontext=system_u:system_r:dom0_t tcontext=system_u:system_r:domU_t tclass=domain

avc:  denied  { settime } for domid=0 target=1 scontext=system_u:system_r:dom0_t
tcontext=system_u:system_r:domU_t tclass=domain
