Though there is no other 4421| | application types that currently need discovery (NRs 4422| | accept notifications from contextEngineIDs that derive 4423| | from the NO not the NR). Also a lame excuse for doing 4424| | it here. 4425| | 3) Less important technically, but the net-snmp agent 4426| | doesn't currently handle registrations of different 4427| | engineIDs either and it would have been a lot more work 4428| | to implement there since we'd need to support that 4429| | first. :-/ Supporting multiple context engineIDs should 4430| | be done anyway, so it's not a valid excuse here. 4431| | 4) There is a lot less to do if we trump the agent at this 4432| | point; IE, the agent does a lot more unnecessary 4433| | processing when the only thing that should ever be in 4434| | this context by definition is the single scalar. 4435| | */ 4436| | 4437| | /* special RFC5343 engineID discovery engineID check */ 4438| 0| if (!netsnmp_ds_get_boolean(NETSNMP_DS_LIBRARY_ID, ------------------ | | 48| 0|#define NETSNMP_DS_LIBRARY_ID 0 ------------------ | Branch (4438:13): [True: 0, False: 0] ------------------ 4439| 0| NETSNMP_DS_LIB_NO_DISCOVERY) && ------------------ | | 98| 0|#define NETSNMP_DS_LIB_NO_DISCOVERY 38 /* don't support RFC5343 contextEngineID discovery */ ------------------ 4440| 0| SNMP_MSG_RESPONSE != pdu->command && ------------------ | | 127| 0|#define SNMP_MSG_RESPONSE (ASN_CONTEXT | ASN_CONSTRUCTOR | 0x2) /* a2=162 */ | | ------------------ | | | | 92| 0|#define ASN_CONTEXT 0x80U | | ------------------ | | #define SNMP_MSG_RESPONSE (ASN_CONTEXT | ASN_CONSTRUCTOR | 0x2) /* a2=162 */ | | ------------------ | | | | 96| 0|#define ASN_CONSTRUCTOR 0x20U | | ------------------ ------------------ | Branch (4440:13): [True: 0, False: 0] ------------------ 4441| 0| NULL != pdu->contextEngineID && ------------------ | Branch (4441:13): [True: 0, False: 0] ------------------ 4442| 0| pdu->contextEngineIDLen == 5 && ------------------ | Branch (4442:13): [True: 0, False: 0] ------------------ 4443| 0| pdu->contextEngineID[0] == 0x80 && ------------------ | Branch (4443:13): [True: 0, False: 0] ------------------ 4444| 0| pdu->contextEngineID[1] == 0x00 && ------------------ | Branch (4444:13): [True: 0, False: 0] ------------------ 4445| 0| pdu->contextEngineID[2] == 0x00 && ------------------ | Branch (4445:13): [True: 0, False: 0] ------------------ 4446| 0| pdu->contextEngineID[3] == 0x00 && ------------------ | Branch (4446:13): [True: 0, False: 0] ------------------ 4447| 0| pdu->contextEngineID[4] == 0x06) { ------------------ | Branch (4447:13): [True: 0, False: 0] ------------------ 4448| | 4449| | /* define a result so it doesn't get past us at this point 4450| | and gets dropped by future parts of the stack */ 4451| 0| result = SNMPERR_JUST_A_CONTEXT_PROBE;
