Subject: [PATCH 2/8] netfilter: ipv6: add IPSKB_REROUTED exclusion to NF_HOOK/POSTROUTING invocation
Date: Tue, 13 Apr 2010 14:37:41 +0200 [thread overview]
Message-ID: <1271162268-28131-3-git-send-email-jengelh@medozas.de> (raw)
In-Reply-To: <1271162268-28131-1-git-send-email-jengelh@medozas.de>
Similar to how IPv4's ip_output.c works, have ip6_output also check
the IPSKB_REROUTED flag. It will be set from xt_TEE for cloned packets
since Xtables can currently only deal with a single packet in flight
at a time.
