[Xen-devel] Dom0 crash after bad use of gntdev

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

I have a bug in some code running in Dom0 that uses gntdev and it's
crashing Dom0 when it goes wrong. I'm not sure exactly what it's doing
wrong but is it acceptable for this to happen? The things I know are
that I'm passing an invalid array to xc_gnttab_map_grant_refs and then
unmapping it without checking the result of the mapping. I'm not sure
what else is going on aside from those two things.
