If exclude_non_seclabel_mounts() ever gets run on a kernel where
/proc/mounts only contains three columns, mount_info[3] will be used
"without being initialized in "strtok(mount_info[3], ",")" because
variable index would be 3 at the end of this loop:
index = 0;
item = strtok(buf, " ");
while (item != NULL) {
mount_info[index] = item;
if (index == 3)
break;
index++;
item = strtok(NULL, " ");
}
Swap the condition on index and its increment so that it gets to 4 only
when there are at least four columns.
This issue has been found using clang's static analyzer.
