* net/mlx5e: E-switch, Add steering drop countersEugenia Emantayev2018-01-09
| | | | | | | | | | | | | | | | | | | | | | | | Add flow counters to count packets dropped due to drop rules configured in eswitch egress and ingress ACLs. These counters will count VFs violations and incoming traffic drops. Will be presented on hypervisor via standard 'ip -s link show' command. Example: "ip -s link show dev enp5s0f0" 6: enp5s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether 24:8a:07:a5:28:f0 brd ff:ff:ff:ff:ff:ff RX: bytes packets errors dropped overrun mcast 0 0 0 0 0 2 TX: bytes packets errors dropped carrier collsns 1406 17 0 0 0 0 vf 0 MAC 00:00:ca:fe:ca:fe, vlan 5, spoof checking off, link-state auto, trust off, query_rss off RX: bytes packets mcast bcast dropped 1666 29 14 32 0 TX: bytes packets dropped 2880 44 2412 Signed-off-by: Eugenia Emantayev <eugenia@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

* net/mlx5e: Support offloading TC NIC hairpin flowsOr Gerlitz2018-01-09
| | | | | | | | | | | | | | | | | | | | | | | We refer to TC NIC rule that involves forwarding as "hairpin". All hairpin rules from the current NIC device (called "func" in the code) to a given NIC device ("peer") are steered into the same hairpin RQ/SQ pair. The hairpin pair is set on demand and removed when there are no TC rules that need it. Here's a TC rule that matches on icmp, does header re-write of the dst mac and hairpin from RX/enp1s2f1 to TX/enp1s2f2 (enp1s2f1/2 are two mlx5 devices): tc filter add dev enp1s2f1 protocol ip parent ffff: prio 2 flower skip_sw ip_proto icmp action pedit ex munge eth dst set 10:22:33:44:55:66 pipe action mirred egress redirect dev enp1s2f2 Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

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>

| * netfilter: nf_tables: flow offload expressionPablo Neira Ayuso2018-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new instruction for the nf_tables VM that allows us to specify what flows are offloaded into a given flow table via name. This new instruction creates the flow entry and adds it to the flow table. Only established flows, ie. we have seen traffic in both directions, are added to the flow table. You can still decide to offload entries at a later stage via packet counting or checking the ct status in case you want to offload assured conntracks. This new extension depends on the conntrack subsystem. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the IPv4 flow table type, that implements the datapath flow table to forward IPv4 traffic. Rationale is: 1) Look up for the packet in the flow table, from the ingress hook. 2) If there's a hit, decrement ttl and pass it on to the neighbour layer for transmission. 3) If there's a miss, packet is passed up to the classic forwarding path.

| * netfilter: add generic flow table infrastructurePablo Neira Ayuso2018-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch defines the API to interact with flow tables, this allows to add, delete and lookup for entries in the flow table. This also adds the generic garbage code that removes entries that have expired, ie. no traffic has been seen for a while. Users of the flow table infrastructure can delete entries via flow_offload_dead(), which sets the dying bit, this signals the garbage collector to release an entry from user context.

| * netfilter: nf_tables: add flow table netlink frontendPablo Neira Ayuso2018-01-08
| | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a netlink control plane to create, delete and dump flow tables. Flow tables are identified by name, this name is used from rules to refer to an specific flow table. Flow tables use the rhashtable class and a generic garbage collector to remove expired entries. This also adds the infrastructure to add different flow table types, so we can add one for each layer 3 protocol family. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
| * netfilter: nf_conntrack: add IPS_OFFLOAD status bitPablo Neira Ayuso2018-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new bit tells us that the conntrack entry is owned by the flow table offload infrastructure. # cat /proc/net/nf_conntrack ipv4 2 tcp 6 src=10.141.10.2 dst=147.75.205.195 sport=36392 dport=443 src=147.75.205.195 dst=192.168.2.195 sport=443 dport=36392 [OFFLOAD] mark=0 zone=0 use=2 Note the [OFFLOAD] tag in the listing. The timer of such conntrack entries look like stopped from userspace. In practise, to make sure the conntrack entry does not go away, the conntrack timer is periodically set to an arbitrary large value that gets refreshed on every iteration from the garbage collector, so it never expires- and they display no internal state in the case of TCP flows. This allows us to save a bitcheck from the packet path via nf_ct_is_expired(). Conntrack entries that have been offloaded to the flow table infrastructure cannot be deleted/flushed via ctnetlink. The flow table infrastructure is also responsible for releasing this conntrack entry. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| * netfilter: remove defensive check on malformed packets from raw socketsPablo Neira Ayuso2018-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Users cannot forge malformed IPv4/IPv6 headers via raw sockets that they can inject into the stack. Specifically, not for IPv4 since 55888dfb6ba7 ("AF_RAW: Augment raw_send_hdrinc to expand skb to fit iphdr->ihl (v2)"). IPv6 raw sockets also ensure that packets have a well-formed IPv6 header available in the skbuff. At quick glance, br_netfilter also validates layer 3 headers and it drops malformed both IPv4 and IPv6 packets. Therefore, let's remove this defensive check all over the place.

| | | | | | | | | | | | | | | | Since NFPROTO_INET is handled from the core, we don't need to maintain extra infrastructure in nf_tables to handle the double hook registration, one for IPv4 and another for IPv6. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
| * netfilter: nf_tables_inet: don't use multihook infrastructure anymorePablo Neira Ayuso2018-01-08
| | | | | | | | | | | | | | Use new native NFPROTO_INET support in netfilter core, this gets rid of ad-hoc code in the nf_tables API codebase. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
| * netfilter: core: support for NFPROTO_INET hook registrationPablo Neira Ayuso2018-01-08
| | | | | | | | | | | | | | Expand NFPROTO_INET in two hook registrations, one for NFPROTO_IPV4 and another for NFPROTO_IPV6. Hence, we handle NFPROTO_INET from the core. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
| * netfilter: core: pass family as parameter to nf_remove_net_hook()Pablo Neira Ayuso2018-01-08
| | | | | | | | | | | | So static_key_slow_dec applies to the family behind NFPROTO_INET. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
| * netfilter: core: pass hook number, family and device to nf_find_hook_list()Pablo Neira Ayuso2018-01-08
| | | | | | | | | | | | | | Instead of passing struct nf_hook_ops, this is needed by follow up patches to handle NFPROTO_INET from the core. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
| * netfilter: core: add nf_remove_net_hookPablo Neira Ayuso2018-01-08
| | | | | | | | | | | | | | Just a cleanup, __nf_unregister_net_hook() is used by a follow up patch when handling NFPROTO_INET as a real family from the core. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
| * netfilter: nf_tables: add nft_set_is_anonymous() helperPablo Neira Ayuso2018-01-08
| | | | | | | | | | | | Add helper function to test for the NFT_SET_ANONYMOUS flag. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
