  commit 89d40f0682f9ad37091cc53685f3ecf63a44bb72
  Author: Jan Beulich <jbeulich@xxxxxxxx>
  Date:   Wed Aug 25 15:24:37 2021 +0200
  
      x86/p2m: guard (in particular) identity mapping entries
      
      Such entries, created by set_identity_p2m_entry(), should only be
      destroyed by clear_identity_p2m_entry(). However, similarly, entries
      created by set_mmio_p2m_entry() should only be torn down by
      clear_mmio_p2m_entry(), so the logic gets based upon p2m_mmio_direct as
      the entry type (separation between "ordinary" and 1:1 mappings would
      require a further indicator to tell apart the two).
      
      As to the guest_remove_page() change, commit 48dfb297a20a ("x86/PVH:
      allow guest_remove_page to remove p2m_mmio_direct pages"), which
      introduced the call to clear_mmio_p2m_entry(), claimed this was done for
      hwdom only without this actually having been the case. However, this
      code shouldn't be there in the first place, as MMIO entries shouldn't be
      dropped this way. Avoid triggering the warning again that 48dfb297a20a
      silenced by an adjustment to xenmem_add_to_physmap_one() instead.
      
      Note that guest_physmap_mark_populate_on_demand() gets tightened beyond
      the immediate purpose of this change.
      
      Note also that I didn't inspect code which isn't security supported,
      e.g. sharing, paging, or altp2m.
      
      This is CVE-2021-28694 / part of XSA-378.

  commit 89d40f0682f9ad37091cc53685f3ecf63a44bb72
  Author: Jan Beulich <jbeulich@xxxxxxxx>
  Date:   Wed Aug 25 15:24:37 2021 +0200
  
      x86/p2m: guard (in particular) identity mapping entries
      
      Such entries, created by set_identity_p2m_entry(), should only be
      destroyed by clear_identity_p2m_entry(). However, similarly, entries
      created by set_mmio_p2m_entry() should only be torn down by
      clear_mmio_p2m_entry(), so the logic gets based upon p2m_mmio_direct as
      the entry type (separation between "ordinary" and 1:1 mappings would
      require a further indicator to tell apart the two).
      
      As to the guest_remove_page() change, commit 48dfb297a20a ("x86/PVH:
      allow guest_remove_page to remove p2m_mmio_direct pages"), which
      introduced the call to clear_mmio_p2m_entry(), claimed this was done for
      hwdom only without this actually having been the case. However, this
      code shouldn't be there in the first place, as MMIO entries shouldn't be
      dropped this way. Avoid triggering the warning again that 48dfb297a20a
      silenced by an adjustment to xenmem_add_to_physmap_one() instead.
      
      Note that guest_physmap_mark_populate_on_demand() gets tightened beyond
      the immediate purpose of this change.
      
      Note also that I didn't inspect code which isn't security supported,
      e.g. sharing, paging, or altp2m.
      
      This is CVE-2021-28694 / part of XSA-378.
