Upstream fix: commit df9fe124d650bc438c531673492569da87523d20 Author: Ján Tomko <jtomko> AuthorDate: 2016-01-14 14:31:17 +0100 Commit: Ján Tomko <jtomko> CommitDate: 2016-01-20 09:32:59 +0100 leaseshelper: fix crash when no mac is specified If dnsmasq specified DNSMASQ_IAID (so we're dealing with an IPv6 lease) but no DNSMASQ_MAC, we skip creation of the new lease object. Also skip adding it to the leases array. https://bugzilla.redhat.com/show_bug.cgi?id=1202350 git describe: v1.3.1-12-gdf9fe12 backported as v1.2.13.2-2-g931888e and v1.2.18.2-2-gd5ef3cb
