Revision 5caaf5346892d1e7f0b8b7223062644f8538483f authored by Ian Munsie on 07 July 2015, 05:45:46 UTC, committed by Michael Ellerman on 08 July 2015, 05:17:46 UTC
This patch makes the mmap call fail outright if the requested region is larger than the problem state area assigned to the context so the error is reported immediately rather than waiting for an attempt to access an address out of bounds. Although we never expect users to map more than the assigned problem state area and are not aware of anyone doing this (other than for testing), this does have the potential to break users if someone has used a larger range regardless. I'm submitting it for consideration, but if this change is not considered acceptable the previous patch is sufficient to prevent access out of bounds without breaking anyone.
