oa_soap NULL dereference code paths

[openhpi2]

We have three instances of code like this: rdr = oh_get_rdr_by_type(oh_handler->rptcache, resource_id, SAHPI_SENSOR_RDR, OA_SOAP_SEN_TEMP_STATUS);

sensor_info = (struct oa_soap_sensor_info *)oh_get_rdr_data(oh_handler->rptcache, resource_id,rdr->RecordId);

The problem is that oh_get_rdr_by_type can potentially return NULL so we will crash with rdr->RecordId. We need to make this a bit more robust.

Instances:

• plugins/oa_soap/oa_soap_interconnect_event.c +795
• plugins/oa_soap/oa_soap_enclosure_event.c +146
• plugins/oa_soap/oa_soap_server_event.c +1282
