When updating the PBMC register, we read its current value,
modify desired fields, then write it back.
The port_buffer_size field within PBMC is Read-Only (RO).
If this RO field contains a non-zero value when read,
attempting to write it back will cause the entire PBMC
register update to fail.
This commit ensures port_buffer_size is explicitly cleared
to zero after reading the PBMC register but before writing
back the modified value.
This allows updates to other fields in the PBMC register to succeed.

Although setup_ns() set net.ipv4.conf.default.rp_filter=0,
loading certain module such as ipip will automatically create a tunl0 interface
in all netns including new created ones. In the script, this is before than
default.rp_filter=0 applied, as a result tunl0.rp_filter remains set to 1
which causes the test report FAIL when ipip module is preloaded.
Before fix:

After fix:

The scratchmap size depends on the number of elements in the set.
For huge sets, each scratch map can easily require very large

The matching algorithm has implemented thrice:
1. data path lookup, generic version
2. data path lookup, avx2 version
3. control plane lookup
Merge 1 and 3 by refactoring pipapo_get as a common helper, then make
nft_pipapo_lookup and nft_pipapo_get both call the common helper.
Aside from the code savings this has the benefit that we no longer allocate
temporary scratch maps for each control plane get and insertion operation.

This stems from a time when sets and nft_dynset resided in different kernel
modules. We can replace this with a direct call.
We could even remove both ->update and ->delete, given its only
supported by rhashtable, but on the off-chance we'll see runtime
add/delete for other types or a new set type keep that as-is for now.

Return the extension pointer instead of passing it as a function
argument to be filled in by the callee.
As-is, whenever false is returned, the extension pointer is not used.
For all set types, when true is returned, the extension pointer was set
to the matching element.
Only exception: nft_set_bitmap doesn't support extensions.
Return a pointer to a static const empty element extension container.
return false -> return NULL
return true -> return the elements' extension pointer.
This saves one function argument.

Introduce NFNL_HOOK_TYPE_NFT_FLOWTABLE to distinguish flowtable hooks
from base chain ones. Nested attributes are shared with the old NFTABLES
hook info type since they fit apart from their misleading name.
Old nftables in user space will ignore this new hook type and thus
continue to print flowtable hooks just like before, e.g.:
| family netdev {
| hook ingress device test0 {
| 0000000000 nf_flow_offload_ip_hook [nf_flow_table]
| }
| }
With this patch in place and support for the new hook info type, output
becomes more useful:
| family netdev {
| hook ingress device test0 {
| 0000000000 flowtable ip mytable myft [nf_flow_table]
| }
| }

Some specified options rely on NETFILTER_XTABLES_LEGACY to be enabled.
IP_NF_TARGET_TTL for instance depends on IP_NF_MANGLE which in turn
depends on IP_NF_IPTABLES_LEGACY -> NETFILTER_XTABLES_LEGACY.
Enable relevant iptables config options explicitly, this is needed
to avoid breakage when symbols related to iptables-legacy
will depend on NETFILTER_LEGACY resp. IP_TABLES_LEGACY.
This also means that the classic tables (Kernel modules) will
not be enabled by default, so enable them too.

The seqcount xt_recseq is used to synchronize the replacement of
xt_table::private in xt_replace_table() against all readers such as
ipt_do_table()
To ensure that there is only one writer, the writing side disables
bottom halves. The sequence counter can be acquired recursively. Only the
first invocation modifies the sequence counter (signaling that a writer
is in progress) while the following (recursive) writer does not modify
the counter.
The lack of a proper locking mechanism for the sequence counter can lead
to live lock on PREEMPT_RT if the high prior reader preempts the
writer. Additionally if the per-CPU lock on PREEMPT_RT is removed from
local_bh_disable() then there is no synchronisation for the per-CPU
sequence counter.
The affected code is "just" the legacy netfilter code which is replaced
by "netfilter tables". That code can be disabled without sacrificing
functionality because everything is provided by the newer
implementation. This will only requires the usage of the "-nft" tools
instead of the "-legacy" ones.
The long term plan is to remove the legacy code so lets accelerate the
progress.
Relax dependencies on iptables legacy, replace select with depends on,
this should cause no harm to existing kernel configs and users can still
toggle IP{6}_NF_IPTABLES_LEGACY in any case.
Make EBTABLES_LEGACY, IPTABLES_LEGACY and ARPTABLES depend on
NETFILTER_XTABLES_LEGACY. Hide xt_recseq and its users,
xt_register_table() and xt_percpu_counter_alloc() behind
NETFILTER_XTABLES_LEGACY. Let NETFILTER_XTABLES_LEGACY depend on
!PREEMPT_RT.
This will break selftest expecing the legacy options enabled and will be
addressed in a following patch.

Store firmware version in kvaser_pciefd_fw_version struct, specifying the
different components of the version number.
And drop debug prinout of firmware version, since later patches will expose
it via the devlink interface.

Commit e7607f7d6d81 ("ARM: 9443/1: Require linker to support KEEP within
OVERLAY for DCE") accidentally broke the binutils version restriction
that was added in commit 0d437918fb64 ("ARM: 9414/1: Fix build issue
with LD_DEAD_CODE_DATA_ELIMINATION"), reintroducing the segmentation
fault addressed by that workaround.
Restore the binutils version dependency by using
CONFIG_LD_CAN_USE_KEEP_IN_OVERLAY as an additional condition to ensure
that CONFIG_HAVE_LD_DEAD_CODE_DATA_ELIMINATION is only enabled with
binutils >= 2.36 and ld.lld >= 21.0.0.

After commit d5c8d6e0fa61 ("kbuild: Update assembler calls to use proper
flags and language target"), which updated as-instr to use the
'assembler-with-cpp' language option, the Kbuild version of as-instr
always fails internally for arch/arm with
<command-line>: fatal error: asm/unified.h: No such file or directory
compilation terminated.
because '-include' flags are now taken into account by the compiler
driver and as-instr does not have '$(LINUXINCLUDE)', so unified.h is not
found.
This went unnoticed at the time of the Kbuild change because the last
use of as-instr in Kbuild that arch/arm could reach was removed in 5.7
by commit 541ad0150ca4 ("arm: Remove 32bit KVM host support") but a
stable backport of the Kbuild change to before that point exposed this
potential issue if one were to be reintroduced.
Follow the general pattern of '-include' paths throughout the tree and
make unified.h absolute using '$(srctree)' to ensure KBUILD_AFLAGS can
be used independently.
