ovn-ctl is not able to specify TLS version used by ovsdb-server [master]
Last modified: 2017-06-07 08:54:50 EDT
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
Steps to Reproduce:
1. Configure OVN Southbound DB and OVN Northbound DB to use only TLSv1.2
All TLS version are accepted by OVN Southbound DB and OVN Northbound DB, since configuration is not yet possible.
Only TLSv1.2 is accepted by OVN Southbound DB and OVN Northbound DB
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.
