commit 6e71519769645a9baef50a2c469f887bb1d2d69b
Author: Michael Poole <[email protected]>
Date: Sun Dec 11 14:13:58 2016 -0500
IPcheck: Bugfix for IPv6 /48 rejections from a new /64.
After "IPcheck: Rate-limit connections per IPv6 /48.", if a connection
from a rate-limited /48 came from a /64 that had no current connections,
then `entry` can be null in this path.
