Description Graham Leggett 2021-01-10 14:56:25 UTC 
Description of problem:

Certificate allowed_uses are not indexed by net-snmp. As a result, the trustCert option works the first time snmpd is started, but fails thereafter.

In addition, there is no support for intermediate certificates (they are ignored) and as a result no possibility to use net-snmp with Let's Encrypt.

Version-Release number of selected component (if applicable):

net-snmp-libs-5.8-17.el8

How reproducible:

Always.

Steps to Reproduce:
1. Configure net-snmp for DTLS using localCert and trustCert.
2. Load net-snmp once with empty index.
3. Reload net-snmp.

Actual results:

trustCert is no longer recognised, as the "CA" flag is unindexed and missing.

Expected results:

trustCert works properly.

Additional info:

Patches to update net-snmp to fix this index issue, as well as to properly support CA certificates are available here:
