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: NDavid S. Miller <davem@davemloft.net>

And the frame size which is less than the default value should not be set to the hardware.

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.

When using the MAPv4 packet format, receive checksum offload can be enabled in hardware. The checksum computation over pseudo header is not offloaded but the rest of the checksum computation over the payload is offloaded. This applies only for TCP / UDP packets which are not fragmented. rmnet validates the TCP/UDP checksum for the packet using the checksum from the checksum trailer added to the packet by hardware. The validation performed is as following - 1. Perform 1's complement over the checksum value from the trailer 2. Compute 1's complement checksum over IPv4 / IPv6 header and subtracts it from the value from step 1 3. Computes 1's complement checksum over IPv4 / IPv6 pseudo header and adds it to the value from step 2 4. Subtracts the checksum value from the TCP / UDP header from the value from step 3. 5. Compares the value from step 4 to the checksum value from the TCP / UDP header. 6. If the comparison in step 5 succeeds, CHECKSUM_UNNECESSARY is set and the packet is passed on to network stack. If there is a failure, then the packet is passed on as such without modifying the ip_summed field. The checksum field is also checked for UDP checksum 0 as per RFC 768 and for unexpected TCP checksum of 0. If checksum offload is disabled when using MAPv4 packet format in receive path, the packet is queued as is to network stack without the validations above.

The MAPv4 packet format adds support for RX / TX checksum offload. For a bi-directional UDP stream at a rate of 570 / 146 Mbps, roughly 10% CPU cycles are saved. For receive path, there is a checksum trailer appended to the end of the MAP packet. The valid field indicates if hardware has computed the checksum. csum_start_offset indicates the offset from the start of the IP header from which hardware has computed checksum. csum_length is the number of bytes over which the checksum was computed and the resulting value is csum_value. In the transmit path, a header is appended between the end of the MAP header and the start of the IP packet. csum_start_offset is the offset in bytes from which hardware will compute the checksum if the csum_enabled bit is set. udp_ip4_ind indicates if the checksum value of 0 is valid or not. csum_insert_offset is the offset from the csum_start_offset where hardware will insert the computed checksum. The use of this additional packet format for checksum offload is explained in subsequent patches. Signed-off-by: NSubash Abhinov Kasiviswanathan <subashab@codeaurora.org> Signed-off-by: NDavid S.

The real device over which the rmnet devices are installed also aggregate multiple IP packets and sends them as a single large aggregate frame to the hardware. This causes degraded throughput for TCP TX due to bufferbloat. To overcome this problem, pacing shift value of 8 is set using the sk_pacing_shift_update() helper. This value was determined based on experiments with a single stream TCP TX using iperf for a duration of 30s.
