Replace all the occurrences of FIELD_SIZEOF() with sizeof_field() except
at places where these are defined. Later patches will remove the unused
definition of FIELD_SIZEOF().
This patch is generated using following script:

With indirect blocks, a driver can register for callbacks from a device
that is does not 'own', for example, a tunnel device. When registering to
or unregistering from a new device, a callback is triggered to generate
a bind/unbind event. This, in turn, allows the driver to receive any
existing rules or to properly clean up installed rules.
When first added, it was assumed that all indirect block registrations
would be for ingress offloads. However, the NFP driver can, in some
instances, support clsact qdisc binds for egress offload.
Change the name of the indirect block callback command in flow_offload to
remove the 'ingress' identifier from it. While this does not change
functionality, a follow up patch will implement a more more generic
callback than just those currently just supporting ingress offload.

Note that the sysctl write accessor functions guarantee that:
net->ipv4.sysctl_ip_prot_sock <= net->ipv4.ip_local_ports.range[0]
invariant is maintained, and as such the max() in selinux hooks is actually spurious.
ie. even though
if (snum < max(inet_prot_sock(sock_net(sk)), low) || snum > high) {
per logic is the same as
if ((snum < inet_prot_sock(sock_net(sk)) && snum < low) || snum > high) {
it is actually functionally equivalent to:
if (snum < low || snum > high) {
which is equivalent to:
if (snum < inet_prot_sock(sock_net(sk)) || snum < low || snum > high) {
even though the first clause is spurious.
But we want to hold on to it in case we ever want to change what what
inet_port_requires_bind_service() means (for example by changing
it from a, by default, [0..1024) range to some sort of set).

inconsistent state.
This patch adds nft_flow_rule_offload_abort() function which undoes the
updates that have been already processed if one command in this

this aborted transaction.

On 32-bit architectures, get_seconds() returns an unsigned 32-bit
time value, which also matches the type used in the nft_meta
code. This will not overflow in year 2038 as a time_t would, but
it still suffers from the overflow problem later on in year 2106.
Change this instance to use the time64_t type consistently
and avoid the deprecated get_seconds().
The nft_meta_weekday() calculation potentially gets a little slower
on 32-bit architectures, but now it has the same behavior as on
64-bit architectures and does not overflow.

The current xt_time driver suffers from the y2038 overflow on 32-bit
architectures, when the time of day calculations break.
Also, on both 32-bit and 64-bit architectures, there is a problem with
info->date_start/stop, which is part of the user ABI and overflows in
in 2106.
Fix the first issue by using time64_t and explicit calls to div_u64()
and div_u64_rem(), and document the seconds issue.
The explicit 64-bit division is unfortunately slower on 32-bit
architectures, but doing it as unsigned lets us use the optimized
division-through-multiplication path in most configurations. This should
be fine, as the code already does not allow any negative time of day
values.
Using u32 seconds values consistently would probably also work and
be a little more efficient, but that doesn't feel right as it would
propagate the y2106 overflow to more place rather than fewer.

If the offset is within the ethernet + vlan header size boundary, then
rebuild the ethernet + vlan header and use it to copy the bytes to the
register. Otherwise, subtract the vlan header size from the offset and
fall back to use skb_copy_bits().
There is one corner case though: If the offset plus the length of the
payload instruction goes over the ethernet + vlan header boundary, then,
fetch as many bytes as possible from the rebuilt ethernet + vlan header
and fall back to copy the remaining bytes through skb_copy_bits().

This patch adds the dataplane hardware offload to the flowtable
infrastructure. Three new flags represent the hardware state of this
flow:
* FLOW_OFFLOAD_HW: This flow entry resides in the hardware.
* FLOW_OFFLOAD_HW_DYING: This flow entry has been scheduled to be remove
from hardware. This might be triggered by either packet path (via TCP
RST/FIN packet) or via aging.
* FLOW_OFFLOAD_HW_DEAD: This flow entry has been already removed from
the hardware, the software garbage collector can remove it from the
software flowtable.
This patch supports for:
* IPv4 only.
* Aging via FLOW_CLS_STATS, no packet and byte counter synchronization
at this stage.
This patch also adds the action callback that specifies how to convert
the flow entry into the flow_rule object that is passed to the driver.

Same as commit 1b4a75108d5b ("netfilter: ipset: Copy the right MAC
address in bitmap:ip,mac and hash:ip,mac sets"), another copy and paste
went wrong in commit 8cc4ccf58379 ("netfilter: ipset: Allow matching on
destination MAC address for mac and ipmac sets").
When I fixed this for IPv4 in 1b4a75108d5b, I didn't realise that
hash:ip,mac sets also support IPv6 as family, and this is covered by a
separate function, hash_ipmac6_kadt().
In hash:ip,mac sets, the first dimension is the IP address, and the
second dimension is the MAC address: check the IPSET_DIM_TWO_SRC flag
in flags while deciding which MAC address to copy, destination or
source.
This way, mixing source and destination matches for the two dimensions
of ip,mac hash type works as expected, also for IPv6. With this setup:
ip netns add A
ip link add veth1 type veth peer name veth2 netns A
ip addr add 2001:db8::1/64 dev veth1
ip -net A addr add 2001:db8::2/64 dev veth2
ip link set veth1 up
ip -net A link set veth2 up
dst=$(ip netns exec A cat /sys/class/net/veth2/address)
ip netns exec A ipset create test_hash hash:ip,mac family inet6
ip netns exec A ipset add test_hash 2001:db8::1,${dst}
ip netns exec A ip6tables -A INPUT -p icmpv6 --icmpv6-type 135 -j ACCEPT
ip netns exec A ip6tables -A INPUT -m set ! --match-set test_hash src,dst -j DROP
ipset now correctly matches a test packet:
# ping -c1 2001:db8::2 >/dev/null
# echo $?

The net,iface equal functions currently compares the full interface
names. In several cases, wildcard (or prefix) matching is useful. For
example, when converting a large iptables rule-set to make use of ipset,
I was able to significantly reduce the number of set elements by making
use of wildcard matching.
Wildcard matching is enabled by adding "wildcard" when adding an element
to a set. Internally, this causes the IPSET_FLAG_IFACE_WILDCARD-flag to
be set. When this flag is set, only the initial part of the interface
name is used for comparison.
Wildcard matching is done per element and not per set, as there are many
cases where mixing wildcard and non-wildcard elements are useful. This
means that is up to the user to handle (avoid) overlapping interface
names.
