Subject: Use AF_UNSPEC instead of AF_UNKNOWN for unspecified local address in add_edge_h().
X-Git-Tag: release-1.1pre12~162
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=8028e01100eb40f64da5e50ef33fbf9e3f8099de

Use AF_UNSPEC instead of AF_UNKNOWN for unspecified local address in add_edge_h().

AF_UNKNOWN is reserved for valid addresses that the local node cannot
parse, but remote nodes possibly can.
