From 58cc06daeacc8158f7471f3331965ec34aa5a172 Mon Sep 17 00:00:00 2001 From: Sergey Popovich Date: Sat, 2 May 2015 19:28:18 +0200 Subject: [PATCH] netfilter: ipset: Fix hashing for ipv6 sets HKEY_DATALEN remains defined after first inclusion of ip_set_hash_gen.h, so it is incorrectly reused for IPv6 code. Undefine HKEY_DATALEN in ip_set_hash_gen.h at the end. Also remove some useless defines of HKEY_DATALEN in ip_set_hash_{ip{,mark,port},netiface}.c as ip_set_hash_gen.h defines it correctly for such set types anyway.
