Subject: Log an error message with the node's name when receiving bad SPTPS packets.
X-Git-Tag: release-1.1pre11~28
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=b90c42a33b78f22b7046da5a5445c712020f30eb

Log an error message with the node's name when receiving bad SPTPS packets.

The SPTPS code doesn't know about nodes, so when it logs an error about
a bad packet, it doesn't log which node it came from. So add a log
message with the node's name and hostname in receive_udppacket().
