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

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.

3. Compute and set 1's complement of partial checksum field in

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.

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.
