#Timeslice 4.6 code#

This release, which includes source code for qemu-traditional and qemu-upstream, contains the following security fixes. However, you can check a=shortlog (between tags qemu-xen-4.6.3 and qemu-xen-4.6.4). This release also contains changes to qemu-upstream, whose changelogs we do not list here as it contains many changes that are not directly releated to the Xen Project Hypervisor and thus this release.

  • cff044b: virtio: error out if guest exceeds virtqueue size.
    • In addition, this release also contains the following fixes to qemu-traditional:
  • eac595f: x86/pv: Remove unsafe bits from the mod_l?_entry() fastpath.
  • dfe85d3: x86/entry: Avoid SMAP violation in compat_create_bounce_frame().
  • db42305: xen/arm: system: Use the correct parameter name in local_irq_restore.
  • ad0e68e: xen/arm: p2m: Pass the vCPU in parameter to get_page_from_gva.
  • 625c3e4: xen/arm: p2m: Restrict usage of get_page_from_gva to the current vCPU.
  • 0905c2a: serial: fix incorrect length of strncmp for dtuart.
  • 6fd1c8e: nested vmx: intercept guest rdmsr for MSR_IA32_VMX_VMFUNC.
