** [tickets:#526] dtm: Error paths use NULL pointer and uninitialized data**
**Status:** fixed

If dtm_node_new() returns NULL, the call to LOG_ER() below will dereference the
returned NULL pointer. This code is in file dtm_node_sockets.c, line 1335 -
1341, tag 4.2.4RC1:
new_node = dtm_node_new(&node);
if (new_node == NULL) {
LOG_ER("DTM: dtm_node_add failed .node_ip: %s, node_id:
%u", new_node->node_ip, new_node->node_id);
dtm_comm_socket_close(&new_conn_sd);
goto node_fail;
}
Also, if inet_ntop() fails, the error message will contain the uninitialized
output buffer from from inet_ntop().
