      mm: Fix MREMAP_DONTUNMAP accounting on VMA merge · dadbd85f
      Brian Geffon authored
      When remapping a mapping where a portion of a VMA is remapped
      into another portion of the VMA it can cause the VMA to become
      split. During the copy_vma operation the VMA can actually
      be remerged if it's an anonymous VMA whose pages have not yet
      been faulted. This isn't normally a problem because at the end
      of the remap the original portion is unmapped causing it to
      become split again.
      
      However, MREMAP_DONTUNMAP leaves that original portion in place which
      means that the VMA which was split and then remerged is not actually
      split at the end of the mremap. This patch fixes a bug where
      we don't detect that the VMAs got remerged and we end up
      putting back VM_ACCOUNT on the next mapping which is completely
      unreleated. When that next mapping is unmapped it results in
      incorrectly unaccounting for the memory which was never accounted,
      and eventually we will underflow on the memory comittment.
      
      There is also another issue which is similar, we're currently
      accouting for the number of pages in the new_vma but that's wrong.
      We need to account for the length of the remap operation as that's
      all that is being added. If there was a mapping already at that
      location its comittment would have been adjusted as part of
      the munmap at the start of the mremap.
      
      A really simple repro can be seen in:
