From 77c102c26ead946fe7589d4bddcdfa5cb431ebfe Mon Sep 17 00:00:00 2001 From: Jeff Cody Date: Fri, 24 Jul 2015 10:26:52 -0400 Subject: [PATCH] block: qemu-iotests - add check for multiplication overflow in vpc 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).
