From 7d489dcdf5fd71b5052ffd401b869a627e1c751f Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 6 Jul 2015 12:15:12 -0600 Subject: [PATCH] vfio: fix return type of pread size_t is an unsigned type, thus the error case is never reached in the below call to pread. If bytes is negative, it will be seen as a very high positive value. Spotted by Coverity.
