Subject[PATCH 3.4 15/32] ipv6: fix leaking uninitialized port number of offender sockaddr
Date
3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hannes Frederic Sowa <hannes@stressinduktion.org>

[ Upstream commit 1fa4c710b6fe7b0aac9907240291b6fe6aafc3b8 ]

Offenders don't have port numbers, so set it to 0.
