Subject: Do not append an address to ANS_KEY messages if we don't know any address.
X-Git-Tag: release-1.0.14~47
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=4b6a9f1c1f645ce5989692655337d9e23ca28648;hp=798fa2f04c52b0639713f74b1195847bec40c16a

Do not append an address to ANS_KEY messages if we don't know any address.

This would let tinc raise an exception when an ANS_KEY request crossed a
DEL_EDGE request for the node sending the key.
