      KVM: MMU: Fix memory leak on guest demand faults · e48bb497
      Avi Kivity 提交于
      While backporting 72dc67a6, a gfn_to_page()
      call was duplicated instead of moved (due to an unrelated patch not being
      present in mainline).  This caused a page reference leak, resulting in a
      fairly massive memory leak.
      
      Fix by removing the extraneous gfn_to_page() call.

      KVM: VMX: Restore tss even on x86_64 · 5dc83262
      Avi Kivity 提交于
      The vmx hardware state restore restores the tss selector and base address, but
      not its length.  Usually, this does not matter since most of the tss contents
      is within the default length of 0x67.  However, if a process is using ioperm()
      to grant itself I/O port permissions, an additional bitmap within the tss,
      but outside the default length is consulted.  The effect is that the process
      will receive a SIGSEGV instead of transparently accessing the port.
      
      Fix by restoring the tss length.  Note that i386 had this working already.
      
      Closes bugzilla 10246.
