2018-01-09net/mlx5e: E-switch, Add steering drop countersEugenia Emantayev4-2/+112
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>

2018-01-09net/mlx5e: Support offloading TC NIC hairpin flowsOr Gerlitz2-12/+172
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>

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>

2018-01-08net: hns3: Unify the strings display of packet statisticsJian Shen4-66/+69
Some members of packet statistics are named in different styles. This patch unifies them with new internal name rules, the main modification are below: trans --> tx rcv --> rx rcb_q%d_tx --> txq#%d rcb_q%d_rx --> rxq#%d sw_err_cnt(tx side) --> tx_dropped sw_err_cnt(rx side) --> rx_dropped pkts --> packets tx_err_cnt --> errors rx_err_cnt --> errors Signed-off-by: Jian Shen <shenjian15@huawei.com> Signed-off-by: Peng Li <lipeng321@huawei.com> Signed-off-by: David S.

2018-01-08Merge branch 'net-qualcomm-rmnet-Enable-csum-offloads'David S. Miller8-25/+378
Subash Abhinov Kasiviswanathan says: ==================== net: qualcomm: rmnet: Enable csum offloads This series introduces the MAPv4 packet format for checksum offload plus some other minor changes. Patches 1-3 are cleanups. Patch 4 renames the ingress format to data format so that all data formats can be configured using this going forward. Patch 5 uses the pacing helper to improve TCP transmit performance. Patch 6-9 defines the the MAPv4 for checksum offload for RX and TX. A new header and trailer format are used as part of MAPv4. For RX checksum offload, only the 1's complement of the IP payload portion is computed by hardware. The meta data from RX header is used to verify the checksum field in the packet. Note that the IP packet and its field itself is not modified by hardware. This gives metadata to help with the RX checksum. For TX, the required metadata is filled up so hardware can compute the checksum.
