RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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:
