cops: try to avoid uninitialized warning error
Valgrind 3.11.0 on the Ubuntu 16.04 buildbot reports that
cops_call->solicited is not initialized:
pdus_array = (GPtrArray *)wmem_map_lookup(cops_conv_info->pdus_tree, GUINT_TO_POINTER(handle_value));
/* ... */
for (i=0; i < pdus_array->len; i++) {
cops_call = (cops_call_t*)g_ptr_array_index(pdus_array, i);
if ( /* ... */
( (cops_call->op_code == COPS_MSG_KA && !(cops_call->solicited)) &&
^^^^^^^^^^^^^^^^^^^^
which is clearly bogus since the only place where cops_call could be
created is a few lines up:
ver_flags = tvb_get_guint8(tvb, offset);
is_solicited = (lo_nibble(ver_flags) == 0x01);
/* ... */
pdus_array = (GPtrArray *)wmem_map_lookup(cops_conv_info->pdus_tree, GUINT_TO_POINTER(handle_value));
if (pdus_array == NULL) {
pdus_array = g_ptr_array_new();
wmem_map_insert(cops_conv_info->pdus_tree, GUINT_TO_POINTER(handle_value), pdus_array);
}
/* ... */
cops_call = wmem_new(wmem_file_scope(), cops_call_t);
cops_call->op_code = op_code;
cops_call->solicited = is_solicited;
/* ... */
g_ptr_array_add(pdus_array, cops_call);
Try to zero the whole structure to avoid this bogus warning.
