we make the ranges inside constant we won't be able to
make range structs const. The ranges are not modified

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next. Mostly
nf_tables updates with two patches for connlabel and br_netfilter.
1) Rename function name to perform on-demand GC for rbtree elements,
and replace async GC in rbtree by sync GC. Patches from Florian Westphal.
2) Use commit_mutex for NFT_MSG_GETRULE_RESET to ensure that two
concurrent threads invoking this command do not underrun stateful
objects. Patches from Phil Sutter.
3) Use single hook to deal with IP and ARP packets in br_netfilter.
Patch from Florian Westphal.
4) Use atomic_t in netns->connlabel use counter instead of using a
spinlock, also patch from Florian.
5) Cleanups for stateful objects infrastructure in nf_tables.
Patches from Phil Sutter.
6) Flush path uses opaque set element offered by the iterator, instead of
calling pipapo_deactivate() which looks up for it again.
7) Set backend .flush interface always succeeds, make it return void
instead.
8) Add struct nft_elem_priv placeholder structure and use it by replacing
void * to pass opaque set element representation from backend to frontend
which defeats compiler type checks.
9) Shrink memory consumption of set element transactions, by reducing
struct nft_trans_elem object size and reducing stack memory usage.
10) Use struct nft_elem_priv also for set backend .insert operation too.
11) Carry reset flag in nft_set_dump_ctx structure, instead of passing it
as a function argument, from Phil Sutter.

RTAX_FEATURE_ALLFRAG was added before the first git commit:
https://www.mail-archive.com/bk-commits-head@vger.kernel.org/msg03399.html
The feature would send packets to the fragmentation path if a box
receives a PMTU value with less than 1280 byte. However, since commit
9d289715eb ("ipv6: stop sending PTB packets for MTU < 1280"), such
message would be simply discarded. The feature flag is neither supported
in iproute2 utility. In theory one can still manipulate it with direct
netlink message, but it is not ideal because it was based on obsoleted
guidance of RFC-2460 (replaced by RFC-8200).
The feature would always test false at the moment, so remove related
code or mark them as unused.

====================
Netfilter fixes for net
This patch contains two late Netfilter's flowtable fixes for net:
1) Flowtable GC pushes back packets to classic path in every GC run,
ie. every second. This is because NF_FLOW_HW_ESTABLISHED is only
used by sched/act_ct (never set) and IPS_SEEN_REPLY might be unset
by the time the flow is offloaded (this status bit is only reliable
in the sched/act_ct datapath).
2) sched/act_ct logic to push back packets to classic path to reevaluate
if UDP flow is unidirectional only applies if IPS_HW_OFFLOAD_BIT is
set on and no hardware offload request is pending to be handled.
From Vlad Buslov.
These two patches fixes two problems that were introduced in the
previous 6.5 development cycle.

Since 41f2c7c342 ("net/sched: act_ct: Fix promotion of offloaded
unreplied tuple"), flowtable GC pushes back flows with IPS_SEEN_REPLY
back to classic path in every run, ie. every second. This is because of
a new check for NF_FLOW_HW_ESTABLISHED which is specific of sched/act_ct.
In Netfilter's flowtable case, NF_FLOW_HW_ESTABLISHED never gets set on
and IPS_SEEN_REPLY is unreliable since users decide when to offload the
flow before, such bit might be set on at a later stage.
Fix it by adding a custom .gc handler that sched/act_ct can use to
deal with its NF_FLOW_HW_ESTABLISHED bit.

net->ct.labels_used was meant to convey 'number of ip/nftables rules
that need the label extension allocated'.
act_ct enables this for each net namespace, which voids all attempts
to avoid ct->ext allocation when possible.
Move this increment to the control plane to request label extension
space allocation only when its needed.

in the current MPTCP control plane, all operations use a netlink
attribute of the same type "MPTCP_PM_ATTR". However, add/del/get/flush
operations only parse the first element in the message _ the one that
describes MPTCP endpoints (that was named MPTCP_PM_ATTR_ADDR and
mostly used in ADD_ADDR operations _ probably the similarity of "attr",
"addr" and "add" might cause some confusion to human readers).
Convert MPTCP from 'small_ops' to 'ops', thus allowing different attributes
for each single operation, hopefully makes all this clearer to human
readers.
- use a separate attribute set for add/del/get/flush address operation,
binary compatible with the existing one, to store the endpoint address.
MPTCP_PM_ENDPOINT_ADDR is added to the uAPI (with the same value as
MPTCP_PM_ATTR_ADDR) for these operations.
- convert mptcp_pm_ops[] and add policy files accordingly.
this prepares MPTCP control plane to be described as YAML spec.

Instead of copying struct nft_set_elem into struct nft_trans_elem, store
the pointer to the opaque set element object in the transaction. Adapt
set backend API (and set backend implementations) to take the pointer to
opaque set element representation whenever required.
This patch deconstifies .remove() and .activate() set backend API since
these modify the set element opaque object. And it also constify
nft_set_elem_ext() this provides access to the nft_set_ext struct
without updating the object.
According to pahole on x86_64, this patch shrinks struct nft_trans_elem
size from 216 to 24 bytes.
This patch also reduces stack memory consumption by removing the
template struct nft_set_elem object, using the opaque set element object
instead such as from the set iterator API, catchall elements and the get
element command.

Add placeholder structure and place it at the beginning of each struct
nft_*_elem for each existing set backend, instead of exposing elements
as void type to the frontend which defeats compiler type checks. Use
this pointer to this new type to replace void *.
This patch updates the following set backend API to use this new struct
nft_elem_priv placeholder structure:
- update
- deactivate
- flush
- get
as well as the following helper functions:
- nft_set_elem_ext()
- nft_set_elem_init()
- nft_set_elem_destroy()
- nf_tables_set_elem_destroy()
This patch adds nft_elem_priv_cast() to cast struct nft_elem_priv to
native element representation from the corresponding set backend.
BUILD_BUG_ON() makes sure this .priv placeholder is always at the top
of the opaque set element representation.

Currently page pool supports the below use cases:
use case 1: allocate page without page splitting using
page_pool_alloc_pages() API if the driver knows
that the memory it need is always bigger than
half of the page allocated from page pool.
use case 2: allocate page frag with page splitting using
page_pool_alloc_frag() API if the driver knows
that the memory it need is always smaller than
or equal to the half of the page allocated from
page pool.
There is emerging use case [1] & [2] that is a mix of the
above two case: the driver doesn't know the size of memory it
need beforehand, so the driver may use something like below to
allocate memory with least memory utilization and performance
penalty:
if (size << 1 > max_size)
page = page_pool_alloc_pages();
else
page = page_pool_alloc_frag();
To avoid the driver doing something like above, add the
page_pool_alloc() API to support the above use case, and update
the true size of memory that is acctually allocated by updating
'*size' back to the driver in order to avoid exacerbating
truesize underestimate problem.
Rename page_pool_free() which is used in the destroy process to
__page_pool_destroy() to avoid confusion with the newly added
API.

Currently when page_pool_create() is called with
PP_FLAG_PAGE_FRAG flag, page_pool_alloc_pages() is only
allowed to be called under the below constraints:
1. page_pool_fragment_page() need to be called to setup
page->pp_frag_count immediately.
2. page_pool_defrag_page() often need to be called to drain
the page->pp_frag_count when there is no more user will
be holding on to that page.
Those constraints exist in order to support a page to be
split into multi fragments.
And those constraints have some overhead because of the
cache line dirtying/bouncing and atomic update.
Those constraints are unavoidable for case when we need a
page to be split into more than one fragment, but there is
also case that we want to avoid the above constraints and
their overhead when a page can't be split as it can only
hold a fragment as requested by user, depending on different
use cases:
use case 1: allocate page without page splitting.
use case 2: allocate page with page splitting.
use case 3: allocate page with or without page splitting
depending on the fragment size.
Currently page pool only provide page_pool_alloc_pages() and
page_pool_alloc_frag() API to enable the 1 & 2 separately,
so we can not use a combination of 1 & 2 to enable 3, it is
not possible yet because of the per page_pool flag
PP_FLAG_PAGE_FRAG.
So in order to allow allocating unsplit page without the
overhead of split page while still allow allocating split
page we need to remove the per page_pool flag in
page_pool_is_last_frag(), as best as I can think of, it seems
there are two methods as below:
1. Add per page flag/bit to indicate a page is split or
not, which means we might need to update that flag/bit
everytime the page is recycled, dirtying the cache line
of 'struct page' for use case 1.
2. Unify the page->pp_frag_count handling for both split and
unsplit page by assuming all pages in the page pool is split
into a big fragment initially.
As page pool already supports use case 1 without dirtying the
cache line of 'struct page' whenever a page is recyclable, we
need to support the above use case 3 with minimal overhead,
especially not adding any noticeable overhead for use case 1,
and we are already doing an optimization by not updating
pp_frag_count in page_pool_defrag_page() for the last fragment
user, this patch chooses to unify the pp_frag_count handling
to support the above use case 3.
There is no noticeable performance degradation and some
justification for unifying the frag_count handling with this
patch applied using a micro-benchmark testing in [1].

by retrieving the socket QoS and checking the encryption

After PA sync has been successfully established and the
first BIGInfo advertising report is received, a new hcon
is added and notified to the ISO layer. The ISO layer
sets the encryption field of the socket and hcon QoS
according to the encryption parameter of the BIGInfo
advertising report event.
After that, the userspace is woken up, and the QoS of the
new PA sync socket can be read, to inspect the encryption
field and follow up accordingly.

Back in 2015, Van Jacobson suggested to use usec resolution in TCP TS values.
This has been implemented in our private kernels.
Goals were :
1) better observability of delays in networking stacks.
2) better disambiguation of events based on TSval/ecr values.
3) building block for congestion control modules needing usec resolution.
Back then we implemented a schem based on private SYN options
to negotiate the feature.
For upstream submission, we chose to use a route attribute,
because this feature is probably going to be used in private
networks [1] [2].
ip route add 10/8 ... features tcp_usec_ts
Note that RFC 7323 recommends a
"timestamp clock frequency in the range 1 ms to 1 sec per tick.",
but also mentions
"the maximum acceptable clock frequency is one tick every 59 ns."
[1] Unfortunately RFC 7323 5.5 (Outdated Timestamps) suggests
to invalidate TS.Recent values after a flow was idle for more
than 24 days. This is the part making usec_ts a problem
for peers following this recommendation for long living
idle flows.
[2] Attempts to standardize usec ts went nowhere:

We want to make the function more generic so that it can be used by
other UDP tunnel implementations such as geneve and vxlan. To do that,
add the following arguments:
- source and destination UDP port;
- ifindex of the output interface, needed by vxlan;
- the tos, because in some cases it is not taken from struct
ip_tunnel_info (for example, when it's inherited from the inner
packet);
- the dst cache, because not all tunnel types (e.g. vxlan) want to
use the one from struct ip_tunnel_info.
With these parameters, the function no longer needs the full struct
ip_tunnel_info as argument and we can pass only the relevant part of
it (struct ip_tunnel_key).
