commit e3bfa4003ceaa2746cdd77655953ab2601acaf9c
Author: Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>
Date:   Wed Apr 1 10:12:19 2015 +0100

    Limit XEN_DOMCTL_memory_mapping hypercall to only process up to 64 GFNs (or 
less)
    
    Said hypercall for large BARs can take quite a while. As such
    we can require that the hypercall MUST break up the request
    in smaller values.
    
    Another approach is to add preemption to it - whether we do the
    preemption using hypercall_create_continuation or returning
    EAGAIN to userspace (and have it re-invocate the call) - either
    way the issue we cannot easily solve is that in 'map_mmio_regions'
    if we encounter an error we MUST call 'unmap_mmio_regions' for the
    whole BAR region.
    
    Since the preemption would re-use input fields such as nr_mfns,
    first_gfn, first_mfn - we would lose the original values -
    and only undo what was done in the current round (i.e. ignoring
    anything that was done prior to earlier preemptions).
    
    Unless we re-used the return value as 'EAGAIN|nr_mfns_done<<10' but
    that puts a limit (since the return value is a long) on the amount
    of nr_mfns that can provided.
    
    This patch sidesteps this problem by:
     - Setting an hard limit of nr_mfns having to be 64 or less.
     - Toolstack adjusts correspondingly to the nr_mfn limit.
     - If the there is an error when adding the toolstack will call the
       remove operation to remove the whole region.
    
    The need to break this hypercall down is for large BARs can take
    more than the guest (initial domain usually) time-slice. This has
    the negative result in that the guest is locked out for a long
    duration and is unable to act on any pending events.
    
    We also augment the code to return zero if nr_mfns instead
    of trying to the hypercall.
    
    This is XSA-125 / CVE-2015-2752.
