Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree: 1) Free hooks via call_rcu to speed up netns release path, from Florian Westphal. 2) Reduce memory footprint of hook arrays, skip allocation if family is not present - useful in case decnet support is not compiled built-in. Patches from Florian Westphal. 3) Remove defensive check for malformed IPv4 - including ihl field - and IPv6 headers in x_tables and nf_tables. 4) Add generic flow table offload infrastructure for nf_tables, this includes the netlink control plane and support for IPv4, IPv6 and mixed IPv4/IPv6 dataplanes. This comes with NAT support too. This patchset adds the IPS_OFFLOAD conntrack status bit to indicate that this flow has been offloaded. 5) Add secpath matching support for nf_tables, from Florian. 6) Save some code bytes in the fast path for the nf_tables netdev, bridge and inet families. 7) Allow one single NAT hook per point and do not allow to register NAT hooks in nf_tables before the conntrack hook, patches from Florian. 8) Seven patches to remove the struct nf_af_info abstraction, instead we perform direct calls for IPv4 which is faster. IPv6 indirections are still needed to avoid dependencies with the 'ipv6' module, but these now reside in struct nf_ipv6_ops. 9) Seven patches to handle NFPROTO_INET from the Netfilter core, hence we can remove specific code in nf_tables to handle this pseudofamily. 10) No need for synchronize_net() call for nf_queue after conversion to hook arrays. Also from Florian. 11) Call cond_resched_rcu() when dumping large sets in ipset to avoid softlockup. Again from Florian. 12) Pass lockdep_nfnl_is_held() to rcu_dereference_protected(), patch from Florian Westphal. 13) Fix matching of counters in ipset, from Jozsef Kadlecsik. 14) Missing nfnl lock protection in the ip_set_net_exit path, also from Jozsef. 15) Move connlimit code that we can reuse from nf_tables into nf_conncount, from Florian Westhal. And asorted cleanups: 16) Get rid of nft_dereference(), it only has one single caller. 17) Add nft_set_is_anonymous() helper function. 18) Remove NF_ARP_FORWARD leftover chain definition in nf_tables_arp. 19) Remove unnecessary comments in nf_conntrack_h323_asn1.c From Varsha Rao. 20) Remove useless parameters in frag_safe_skb_hp(), from Gao Feng. 21) Constify layer 4 conntrack protocol definitions, function parameters to register/unregister these protocol trackers, and timeouts. Patches from Florian Westphal. 22) Remove nlattr_size indirection, from Florian Westphal. 23) Add fall-through comments as -Wimplicit-fallthrough needs this, from Gustavo A. R. Silva. 24) Use swap() macro to exchange values in ipset, patch from Gustavo A. R. Silva. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
