Description of problem: When sending traps on SNMP v3 using net-snmp-5.8-20 in RHEL 8.4, the engineTime value remains zero. This is a problem as the receiving agent does not accept engineTime with a zero value, it expects engineTime and engineBoots values to progress. snmptrap by default runs the code below to set session.engineBoots and session.engineTime for SNMP v3 traps (not inform). ~~~ session.engineBoots = 1; if (session.engineTime == 0) /* not really correct, */ session.engineTime = get_uptime(); /* but it'll work. Sort of. */ ~~~ Version-Release number of selected component (if applicable): net-snmp-5.8-20.el8 How reproducible: Reproduced by customer Steps to Reproduce: 1. Sending traps on SNMP v3 using net-snmp-5.8-20 in RHEL 8.4 2. If receiving agent does not accept engineTime with a zero value, it will fail Actual results: Unable to send SNMP traps. Expected results: Should be able to send SNMP traps. Additional info: Upstream patch is already in place for snmptrap binary. It resolves the issue by setting the library engineBoots and engineTime values before sending.
