Subject: netfilter: nf_ct_reasm: fix conntrack reassembly expire code
From: Haibo Xi <[email protected]>
commit 97cf00e93cc24898493e7a058105e3215257ee04 upstream.
Commit b836c99fd6c9 (ipv6: unify conntrack reassembly expire
code with standard one) use the standard IPv6 reassembly
code(ip6_expire_frag_queue) to handle conntrack reassembly expire.
In ip6_expire_frag_queue, it invoke dev_get_by_index_rcu to get
which device received this expired packet.so we must save ifindex
when NF_conntrack get this packet.
With this patch applied, I can see ICMP Time Exceeded sent
from the receiver when the sender sent out 1/2 fragmented
IPv6 packet.
