From 83170f3beccccd7ceb4f9a0ac0c4dc736afde90c Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Thu, 26 May 2016 19:08:10 +0200 Subject: netfilter: nf_dup_ipv6: set again FLOWI_FLAG_KNOWN_NH at flowi6_flags With the commit 48e8aa6e3137 ("ipv6: Set FLOWI_FLAG_KNOWN_NH at flowi6_flags") ip6_pol_route() callers were asked to to set the FLOWI_FLAG_KNOWN_NH properly and xt_TEE was updated accordingly, but with the later refactor in commit bbde9fc1824a ("netfilter: factor out packet duplication for IPv4/IPv6") the flowi6_flags update was lost. This commit re-add it just before the routing decision.
