[Qemu-devel] [PATCH 50/53] block: qemu-iotests - add check for multiplication overflow in vpc |
Date: |
Thu, 30 Jul 2015 06:33:05 -0500 |
From: Jeff Cody <address@hidden>
This checks that VPC is able to successfully fail (without segfault)
on an image file with a max_table_entries that exceeds 0x40000000.
This table entry is within the valid range for VPC (although too large
for this sample image).
