From aefd9bcf9b6bbb9f1fd99abe5c1c90832be8bb93 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Wed, 21 May 2014 21:45:02 -0600 Subject: [PATCH] conf: fix backing store parse off-by-one Commit 546154e parses the type attribute from a element, but forgot that the earlier commit 9673418 added a placeholder element in the same 1.2.3 release; as a result, the C code was mistakenly allowing "none" as a type. Similarly, the same commit allows "none" as the sub-element type, even though that has been a placeholder since the 0.10.2 release with commit f772b3d. * src/conf/domain_conf.c (virDomainDiskBackingStoreParse): Require non-zero types.
