From 45c3094a6424614e6fea135e4e1afd8e0a65f468 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= Date: Thu, 27 Nov 2014 20:03:13 +0100 Subject: [PATCH] KVM: x86: allow 256 logical x2APICs again MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit While fixing an x2apic bug, 17d68b7 KVM: x86: fix guest-initiated crash with x2apic (CVE-2013-6376) we've made only one cluster available. This means that the amount of logically addressible x2APICs was reduced to 16 and VCPUs kept overwriting themselves in that region, so even the first cluster wasn't set up correctly. This patch extends x2APIC support back to the logical_map's limit, and keeps the CVE fixed as messages for non-present APICs are dropped.
