diff --git a/block/gluster.c b/block/gluster.c index 031596a..addceed 100644 --- a/block/gluster.c +++ b/block/gluster.c @@ -493,8 +493,7 @@ static int qemu_gluster_parse_json(BlockdevOptionsGluster *gconf, Error *local_err = NULL; char *str = NULL; const char *ptr; - size_t num_servers; - int i, type; + int i, type, num_servers; /* create opts info from runtime_json_opts list */ opts = qemu_opts_create(&runtime_json_opts, NULL, 0, &error_abort);
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.)
