ping? any update
Apparently Jaime no longer maintains this, so reassigning to coldpool. Could someone from the list pick it up? It is long overdue.
Submitted where the code have been found: 15sp4,15sp3,15sp2,15sp1,15,12sp5,12sp4/openvswitch TW/openvswitch already fixed by a version update. I believe all fixed.

Our tracking also has these as affected, but based on version numbers I'd say they are not. - SUSE:SLE-12-SP2:Update - SUSE:SLE-12-SP3:Update Could you verify this? Thanks!
