Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains a second batch of Netfilter updates for your net-next tree. This includes a rework of the core hook infrastructure that improves Netfilter performance by ~15% according to synthetic benchmarks. Then, a large batch with ipset updates, including a new hash:ipmac set type, via Jozsef Kadlecsik. This also includes a couple of assorted updates. Regarding the core hook infrastructure rework to improve performance, using this simple drop-all packets ruleset from ingress: nft add table netdev x nft add chain netdev x y { type filter hook ingress device eth0 priority 0\; } nft add rule netdev x y drop And generating traffic through Jesper Brouer's samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh script using -i option. perf report shows nf_tables calls in its top 10: 17.30% kpktgend_0 [nf_tables] [k] nft_do_chain 15.75% kpktgend_0 [kernel.vmlinux] [k] __netif_receive_skb_core 10.39% kpktgend_0 [nf_tables_netdev] [k] nft_do_chain_netdev I'm measuring here an improvement of ~15% in performance with this patchset, so we got +2.5Mpps more. I have used my old laptop Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz 4-cores. This rework contains more specifically, in strict order, these patches: 1) Remove compile-time debugging from core. 2) Remove obsolete comments that predate the rcu era. These days it is well known that a Netfilter hook always runs under rcu_read_lock(). 3) Remove threshold handling, this is only used by br_netfilter too. We already have specific code to handle this from br_netfilter, so remove this code from the core path. 4) Deprecate NF_STOP, as this is only used by br_netfilter. 5) Place nf_state_hook pointer into xt_action_param structure, so this structure fits into one single cacheline according to pahole. This also implicit affects nftables since it also relies on the xt_action_param structure. 6) Move state->hook_entries into nf_queue entry. The hook_entries pointer is only required by nf_queue(), so we can store this in the queue entry instead. 7) use switch() statement to handle verdict cases. 8) Remove hook_entries field from nf_hook_state structure, this is only required by nf_queue, so store it in nf_queue_entry structure. 9) Merge nf_iterate() into nf_hook_slow() that results in a much more simple and readable function. 10) Handle NF_REPEAT away from the core, so far the only client is nf_conntrack_in() and we can restart the packet processing using a simple goto to jump back there when the TCP requires it. This update required a second pass to fix fallout, fix from Arnd Bergmann. 11) Set random seed from nft_hash when no seed is specified from userspace. 12) Simplify nf_tables expression registration, in a much smarter way to save lots of boiler plate code, by Liping Zhang. 13) Simplify layer 4 protocol conntrack tracker registration, from Davide Caratti. 14) Missing CONFIG_NF_SOCKET_IPV4 dependency for udp4_lib_lookup, due to recent generalization of the socket infrastructure, from Arnd Bergmann. 15) Then, the ipset batch from Jozsef, he describes it as it follows: * Cleanup: Remove extra whitespaces in ip_set.h * Cleanup: Mark some of the helpers arguments as const in ip_set.h * Cleanup: Group counter helper functions together in ip_set.h * struct ip_set_skbinfo is introduced instead of open coded fields in skbinfo get/init helper funcions. * Use kmalloc() in comment extension helper instead of kzalloc() because it is unnecessary to zero out the area just before explicit initialization. * Cleanup: Split extensions into separate files. * Cleanup: Separate memsize calculation code into dedicated function. * Cleanup: group ip_set_put_extensions() and ip_set_get_extensions() together. * Add element count to hash headers by Eric B Munson. * Add element count to all set types header for uniform output across all set types. * Count non-static extension memory into memsize calculation for userspace. * Cleanup: Remove redundant mtype_expire() arguments, because they can be get from other parameters. * Cleanup: Simplify mtype_expire() for hash types by removing one level of intendation. * Make NLEN compile time constant for hash types. * Make sure element data size is a multiple of u32 for the hash set types. * Optimize hash creation routine, exit as early as possible. * Make struct htype per ipset family so nets array becomes fixed size and thus simplifies the struct htype allocation. * Collapse same condition body into a single one. * Fix reported memory size for hash:* types, base hash bucket structure was not taken into account. * hash:ipmac type support added to ipset by Tomasz Chilinski. * Use setup_timer() and mod_timer() instead of init_timer() by Muhammad Falak R Wani, individually for the set type families. 16) Remove useless connlabel field in struct netns_ct, patch from Florian Westphal. 17) xt_find_table_lock() doesn't return ERR_PTR() anymore, so simplify {ip,ip6,arp}tables code that uses this. ==================== Signed-off-by: David S.
