Netfilter/IPVS fixes for net

The following patchset contains Netfilter/IPVS fixes for your net tree:

1) Infinite loop in IPVS when net namespace is released, from
   Tan Hu.

2) Do not show negative timeouts in ip_vs_conn by using the new
   jiffies_delta_to_msecs(), patches from Matteo Croce.

3) Set F_IFACE flag for linklocal addresses in ip6t_rpfilter,
   from Florian Westphal.

4) Fix overflow in set size allocation, from Taehee Yoo.

5) Use netlink_dump_start() from ctnetlink to fix memleak from
   the error path, again from Florian.

6) Register nfnetlink_subsys in last place, otherwise netns
   init path may lose race and see net->nft uninitialized data.
   This also reverts previous attempt to fix this by increase
   netns refcount, patches from Florian.

7) Remove conntrack entries on layer 4 protocol tracker module
   removal, from Florian.

8) Use GFP_KERNEL_ACCOUNT for xtables blob allocation, from
   Michal Hocko.

9) Get tproxy documentation in sync with existing codebase,
   from Mate Eckl.

10) Honor preset layer 3 protocol via ctx->family in the new nft_ct
    timeout infrastructure, from Harsha Sharma.

11) Let uapi nfnetlink_osf.h compile standalone with no errors,
    from Dmitry V. Levin.

12) Missing braces compilation warning in nft_tproxy, patch from
    Mate Eclk.

13) Disregard bogus check to bail out on non-anonymous sets from
    the dynamic set update extension.

If set cbs parameters calculated for 1000Mb, but use on 100Mb port
w/o h/w offload (for cpsw offload it doesn't matter), it works
incorrectly. According to the example and testing board, second port
is 100Mb interface. Correct them on recalculated for 100Mb interface.
It allows to use the same command for CBS software implementation for
board in example.

Recently, transparent proxy support has been added to nf_tables so that
this document should be updated with the new information.

- Nft commands are added as alternatives to iptables ones.
- The link for a patched iptables is removed as it is already part of
  the mainline iptables implementation (and the link is dead).
- tcprdr is added as an example implementation of a transparent proxy

Preventing the kernel from responding to ICMP Echo Requests messages
can be useful in several ways. The sysctl parameter
'icmp_echo_ignore_all' can be used to prevent the kernel from
responding to IPv4 ICMP echo requests. For IPv6 pings, such
a sysctl kernel parameter did not exist.

Add the ability to prevent the kernel from responding to IPv6
ICMP echo requests through the use of the following sysctl
parameter : /proc/sys/net/ipv6/icmp/echo_ignore_all.
Update the documentation to reflect this change.

The BTF conflicts were simple overlapping changes.

The virtio_net conflict was an overlap of a fix of statistics counter,
happening alongisde a move over to a bonafide statistics structure
rather than counting value on the stack.

After IPv4 packets are forwarded, the priority of the corresponding SKB
is updated according to the TOS field of IPv4 header. This overrides any
prioritization done earlier by e.g. an skbedit action or ingress-qos-map
defined at a vlan device.

Such overriding may not always be desirable. Even if the packet ends up
being routed, which implies this is an L3 network node, an administrator
may wish to preserve whatever prioritization was done earlier on in the
pipeline.

Therefore introduce a sysctl that controls this behavior. Keep the
default value at 1 to maintain backward-compatible behavior.

The UCAN driver supports the microcontroller-based USB/CAN
adapters from Theobroma Systems. There are two form-factors
that run essentially the same firmware:

* Seal: standalone USB stick ( https://www.theobroma-systems.com/seal )

* Mule: integrated on the PCB of various System-on-Modules from
  Theobroma Systems like the A31-µQ7 and the RK3399-Q7
  ( https://www.theobroma-systems.com/rk3399-q7 )

The USB wire protocol has been designed to be as generic and
hardware-indendent as possible in the hope of being useful for
implementation on other microcontrollers.
