Subject: [PATCH v11 15/26] KVM: s390: Clear Crypto Control Block when using vSIE
Date: Tue, 25 Sep 2018 19:16:30 -0400 [thread overview]
Message-ID: <20180925231641.4954-16-akrowiak@linux.vnet.ibm.com> (raw)
In-Reply-To: <20180925231641.4954-1-akrowiak@linux.vnet.ibm.com>
From: Pierre Morel <pmorel@linux.ibm.com>
When we clear the Crypto Control Block (CRYCB) used by a guest
level 2, the vSIE shadow CRYCB for guest level 3 must be updated
before the guest uses it.
We achieve this by using the KVM_REQ_VSIE_RESTART synchronous
request for each vCPU belonging to the guest to force the reload
of the shadow CRYCB before rerunning the guest level 3.
