X-Git-Tag: release-1.1pre15~70
X-Git-Url: https://tinc-vpn.org/git/browse?a=commitdiff_plain;h=ab13c14a1480561bb9f59ccfbbd6045e0484ce9c;hp=ab13c14a1480561bb9f59ccfbbd6045e0484ce9c;p=tinc

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.
