Summary: Security update for Xen

Details: XEN has been updated to fix various bugs and security issues: * CVE-2013-0153: (XSA 36) To avoid an erratum in early hardware, the Xen AMD IOMMU code by default choose to use a single interrupt remapping table for the whole system. This sharing implied that any guest with a passed through PCI device that is bus mastering capable can inject interrupts into other guests, including domain 0. This has been disabled for AMD chipsets not capable of it. * CVE-2012-6075: qemu: The e1000 had overflows under some conditions, potentially corrupting memory. * CVE-2013-0154: (XSA 37) Hypervisor crash due to incorrect ASSERT (debug build only) * CVE-2012-5634: (XSA-33) A VT-d interrupt remapping source validation flaw was fixed. Also the following bugs have been fixed: * bnc#805094 - xen hot plug attach/detach fails * bnc#802690 - domain locking can prevent a live migration from completing * bnc#797014 - no way to control live migrations o fix logic error in stdiostream_progress o restore logging in xc_save o add options to control migration tunables * bnc#806736: enabling xentrace crashes hypervisor * Upstream patches from Jan 26287-sched-credit-pick-idle.patch 26501-VMX-simplify-CR0-update.patch 26502-VMX-disable-SMEP-when-not-paging.patch 26516-ACPI-parse-table-retval.patch (Replaces CVE-2013-0153-xsa36.patch) 26517-AMD-IOMMU-clear-irtes.patch (Replaces CVE-2013-0153-xsa36.patch) 26518-AMD-IOMMU-disable-if-SATA-combined-mode.patch (Replaces CVE-2013-0153-xsa36.patch) 26519-AMD-IOMMU-perdev-intremap-default.patch (Replaces CVE-2013-0153-xsa36.patch) 26526-pvdrv-no-devinit.patch 26531-AMD-IOMMU-IVHD-special-missing.patch (Replaces CVE-2013-0153-xsa36.patch) * bnc#798188 - Add $network to xend initscript dependencies * bnc#799694 - Unable to dvd or cdrom-boot DomU after xen-tools update Fixed with update to Xen version 4.1.4 * bnc#800156 - L3: HP iLo Generate NMI function not working in XEN kernel * Upstream patches from Jan 26404-x86-forward-both-NMI-kinds.patch 26427-x86-AMD-enable-WC+.patch * bnc#793927 - Xen VMs with more than 2 disks randomly fail to start * Upstream patches from Jan 26332-x86-compat-show-guest-stack-mfn.patch 26333-x86-get_page_type-assert.patch (Replaces CVE-2013-0154-xsa37.patch) 26340-VT-d-intremap-verify-legacy-bridge.patch (Replaces CVE-2012-5634-xsa33.patch) 26370-libxc-x86-initial-mapping-fit.patch * Update to Xen 4.1.4 c/s 23432 * Update xenpaging.guest-memusage.patch add rule for xenmem to avoid spurious build failures * Upstream patches from Jan 26179-PCI-find-next-cap.patch 26183-x86-HPET-masking.patch 26188-x86-time-scale-asm.patch 26200-IOMMU-debug-verbose.patch 26203-x86-HAP-dirty-vram-leak.patch 26229-gnttab-version-switch.patch (Replaces CVE-2012-5510-xsa26.patch) 26230-x86-HVM-limit-batches.patch (Replaces CVE-2012-5511-xsa27.patch) 26231-memory-exchange-checks.patch (Replaces CVE-2012-5513-xsa29.patch) 26232-x86-mark-PoD-error-path.patch (Replaces CVE-2012-5514-xsa30.patch) 26233-memop-order-checks.patch (Replaces CVE-2012-5515-xsa31.patch) 26235-IOMMU-ATS-max-queue-depth.patch 26272-x86-EFI-makefile-cflags-filter.patch 26294-x86-AMD-Fam15-way-access-filter.patch CVE-2013-0154-xsa37.patch * Restore c/s 25751 in 23614-x86_64-EFI-boot.patch.
