ovpn: introduce the ovpn_peer object2025-04-17T10:30:02+00:00Antonio Quartulliantonio@openvpn.net2025-04-15T11:17:22+00:00urn:sha1:80747caef33d77f5c1b3d24644e6d7dae69066b5
An ovpn_peer object holds the whole status of a remote peer
(regardless whether it is a server or a client).
This includes status for crypto, tx/rx buffers, napi, etc.
Only support for one peer is introduced (P2P mode).
Multi peer support is introduced with a later patch.
Along with the ovpn_peer, also the ovpn_bind object is introcued
as the two are strictly related.
An ovpn_bind object wraps a sockaddr representing the local
coordinates being used to talk to a specific peer.
