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 Dominik Holler 2017-06-07 07:20:07 UTC
Description of problem:

The allowed TLS versions for OVN Southbound DB and OVN Northbound DB can be set by the command line option --ssl-protocols of ovsdb-server, which hosts the two DBs.
ovsdb-server is started by ovn-ctl.
But it is not possible to pass the command line option --ssl-protocols by  ovn-ctl, so it is not possible to start ovsdb-server with restricted TLS versions.

Version-Release number of selected component (if applicable): 2.7


How reproducible:


Steps to Reproduce:
1. Configure OVN Southbound DB and OVN Northbound DB to use only TLSv1.2
2.
3.

Actual results:

All TLS version are accepted by OVN Southbound DB and OVN Northbound DB, since configuration is not yet possible.

Expected results:

Only TLSv1.2 is accepted by OVN Southbound DB and OVN Northbound DB

Comment 2 Lance Richardson 2017-06-07 12:54:50 UTC
I don't think we need to add a new option to ovn-ctl. SSL key and
certificate configuration for OVN nb/sb ovsdb-server is handled solely
through db entries (no command-line option for these in ovn-ctl), so
we should do the same for SSL protocol and cipher configuration.

Having these configuration items in the db has the benefit of not having
to restart ovsdb-server if/when they need to be changed.
