Hello cron2, flichtenheld,
I'd like you to reexamine a change. Please visit
http://gerrit.openvpn.net/c/openvpn/+/909?usp=email
to look at the new patch set (#4).
The following approvals got outdated and were removed:
Code-Review+2 by cron2
The change is no longer submittable: Code-Review and checks~ChecksSubmitRule
are unsatisfied now.
Change subject: Mention address if not unspecific on DNS failure
......................................................................
Mention address if not unspecific on DNS failure
With the recent changes breaking configs that included lport 0, it became
apparent that having the address family in the error message when
resolving fails, would have made diagnosis in this case and probably others
much easier.
