Hello plaisthos, flichtenheld,
I'd like you to do a code review.
Please visit
http://gerrit.openvpn.net/c/openvpn/+/1039?usp=email
to review the following change.
Change subject: Multi-socket: local_list clean-up
......................................................................
Multi-socket: local_list clean-up
Optimize the current local_list implementation
by replacing the static array with a resizable
one, as the static allocation serves no real
purpose, particularly on the client side.
Github: #682
