I had a chance to review the net-snmp code. My previous claim was
incorrect -- net-snmp DOES NOT suffer from the problem documented in
this PR. The code in net-snmp which uses kvm_getprocs(3) is for the
hrSW*Run OIDs, which (properly) uses KERN_PROC_ALL to ensure they count
kernel threads for kernel modules.
The hrSystemProcesses OID with net-snmp returns the correct number of
system processes (not including threads). Verification:
icarus# snmpwalk -v2c -c public localhost hrSystemProcesses
HOST-RESOURCES-MIB::hrSystemProcesses.0 = Gauge32: 60
So this PR/issue is specific to bsnmpd. Sorry to waste your time,
The PR should remain open as bsnmpd needs to be fixed.
