From fd4d9c6495109979eb17779e07666c7c11c79c6a Mon Sep 17 00:00:00 2001 From: "Zhang, Chao B" Date: Tue, 16 Aug 2016 10:21:42 +0800 Subject: [PATCH 1/1] SecurityPkg: AuthVariableLib: Fix inconsistent CertDB case 2 steps are used to create/delete a time based variable. For create step 1: Insert Signer Cert to CertDB. Step 2: Insert Payload to Variable. For delete step 1: Delete Variable. Step 2: Delete Cert from CertDB. System may breaks between step 1 & step 2, so CertDB may contains useless Cert in the next reboot. AuthVariableLib choose to sync consistent state between CertDB & Time Auth Variable on initialization. However, it doesn't apply Time Auth attribute check. Now add it.
