Subject: ip6_finish_output2 change broke netfilter xt_TEE target
Date: Tue, 17 Sep 2013 12:54:34 -0700 [thread overview]
Message-ID: <20130917195434.GA8424@linuxace.com> (raw)
The change made in commit 6fd6ce20 (ipv6: Do not depend on rt->n in
ip6_finish_output2) broke the xt_TEE target for IPv6 packets. Instead
of using the nexthop provided in the --gateway option, ip6_finish_output2
is now performing neighbor solicitation for the original daddr in the
copied skb.
Similar breakage occurred in IPv4, and was fixed (in 2ad5b9e4) by using
the flag FLOWI_FLAG_KNOWN_NH. I can find no easy way to make use of that
flag here. Reverting 6fd6ce20 makes TEE work again, but I am not clear
on what problem that commit was attempting to solve. Yoshifuji?
Phil
