From 56faeb9bb6872b3f926b3b3e0452a70beea10af2 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 5 Jun 2017 18:01:38 +0100 Subject: [PATCH] block/gluster.c: Handle qdict_array_entries() failure In qemu_gluster_parse_json(), the call to qdict_array_entries() could return a negative error code, which we were ignoring because we assigned the result to an unsigned variable. Fix this by using the 'int' type instead, which matches the return type of qdict_array_entries() and also the type we use for the loop enumeration variable 'i'. (Spotted by Coverity, CID 1360960.)
