Subject: [PATCH] XSM/policy: Allow the source domain access to settime and setdomainhandle domctls while creating domain.
Date: Thu, 7 Jul 2016 14:45:47 +0100	[thread overview]
Message-ID: <1467899147-22315-1-git-send-email-anshul.makkar@citrix.com> (raw)

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
