+MIME-Version: 1.0 +Content-Type: text/plain; charset=UTF-8 +Content-Transfer-Encoding: 8bit + +My earlier commit be46f61326 was incomplete. It removed caching of +microcode version in the CPU driver, which means the capabilities XML +will see the correct microcode version. But it is also cached in the +QEMU capabilities cache where it is used to detect whether we need to +reprobe QEMU. By missing the second place, the original commit +be46f61326 made the situation even worse since libvirt would report +correct microcode version while still using the old host CPU model +(visible in domain capabilities XML). + +Signed-off-by: Jiri Denemark +Reviewed-by: Ján Tomko +(cherry picked from commit 673c62a3b7855a0685d8f116e227c402720b9ee9) + +CVE-2018-12126, CVE-2018-12127, CVE-2018-12130 + +Conflicts: + src/qemu/qemu_capabilities.c + - virQEMUCapsCacheLookupByArch refactoring (commits + 7948ad4129a and 1a3de67001c) are missing + +Signed-off-by: Jiri Denemark +--- + src/qemu/qemu_capabilities.c | 12 ++++++++---- + src/qemu/qemu_capabilities.h | 3 +-- + src/qemu/qemu_driver.c | 9 +-------- + tests/testutilsqemu.c | 2 +- + 4 files changed, 11 insertions(+), 15 deletions(-) + +diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c +index 4f2051a2bb..96aa1b15e4 100644 +--- a/src/qemu/qemu_capabilities.c ++++ b/src/qemu/qemu_capabilities.c +@@ -4625,7 +4625,7 @@ virQEMUCapsNewData(const char *binary, + priv->libDir, + priv->runUid, + priv->runGid, +- priv->microcodeVersion, ++ virHostCPUGetMicrocodeVersion(), + priv->kernelVersion);
