Subject: Preserve IPv6 scope_id in edges.
X-Git-Tag: release-1.0.29~10
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=48e353e9fdf189c4fd5fa7ebc76a72535b4f6632;hp=48e353e9fdf189c4fd5fa7ebc76a72535b4f6632

Preserve IPv6 scope_id in edges.

When creating an edge after authenticating a peer, we copy the address
used for the TCP connection, but change the port to that used for UDP.
But the way we did it discarded the scope_id for IPv6 addresses. This
prevented UDP communication from working correctly when connecting to a
peer on the same LAN using an IPv6 link-local address.

Thanks to Rafał Leśniak for pointing out this issue.
