Subject: Prevent underflow when sending UDP probes.
X-Git-Url: https://tinc-vpn.org/git/browse?a=commitdiff_plain;h=ca7502b6de1e1ae49a62ad6b7a7ae8b760fa51ff;hp=ca7502b6de1e1ae49a62ad6b7a7ae8b760fa51ff;p=tinc

Prevent underflow when sending UDP probes.

Make sure send_udp_probe_packet() never tries to send a packet smaller
than MIN_PROBE_SIZE, otherwise length calculation could potentially wrap.

Fixes #351 on GitHub.
