Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following batch contains netfilter fixes for your net tree, they are: 1) Fix use after free in nfnetlink when sending a batch for some unsupported subsystem, from Denys Fedoryshchenko. 2) Skip autoload of the nat module if no binding is specified via ctnetlink, from Florian Westphal. 3) Set local_df after netfilter defragmentation to avoid a bogus ICMP fragmentation needed in the forwarding path, also from Florian. 4) Fix potential user after free in ip6_route_me_harder() when returning the error code to the upper layers, from Sergey Popovich. 5) Skip possible bogus ICMP time exceeded emitted from the router (not valid according to RFC) if conntrack zones are used, from Vasily Averin. 6) Fix fragment handling when nf_defrag_ipv4 is loaded but nf_conntrack is not present, also from Vasily. ==================== Signed-off-by: David S.
