The scratchmap size depends on the number of elements in the set.
For huge sets, each scratch map can easily require very large
allocations, e.g. for 100k entries each scratch map will require
close to 64kbyte of memory.

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.

selftests: drv-net: Fix and improve command requirement checking
This series fixes remote command checking and cleans up command
requirement calls across tests.
The first patch fixes require_cmd() incorrectly checking commands
locally even when remote=True was specified due to a missing host
parameter.
The second patch makes require_cmd() usage explicit about local/remote
requirements, avoiding unnecessary test failures and consolidating
duplicate calls.

Make require_cmd() calls explicit about whether commands are needed
locally, remotely, or both.
Since require_cmd() defaults to local=True, tests should explicitly set
local=False when commands are only needed remotely.
- socat: Set local=False since it's only needed on remote hosts.
- iperf3: Use single call with both local=True and remote=True since
it's needed on both hosts.
This avoids unnecessary test failures when commands are missing locally
but available remotely where actually needed, and consolidates a
duplicate require_cmd() call into single call that checks both hosts.

"
These warnings indicate that the stack frame size exceeds 1024 bytes in
these functions.
To resolve this, instead of allocating large memory buffers on the stack,
it is better to use kvzalloc to allocate memory dynamically on the heap.
This approach reduces stack usage and eliminates these frame size warnings.

For basic types we "flatten" setters. If a request "a" has a simple
nest "b" with value "val" we print helpers like:
req_set_a_b(struct a *req, int val)
{
req->_present.a = 1;
req->b._present.val = 1;
req->b.val = ...
}
This is not possible for multi-attr because they have to be allocated
dynamically by the user. Print "object level" setters so that user
preparing the object doesn't have to futz with the presence bits
and other YNL internals.
Add the ability to pass in the variable name to generated setters.
Using "req" here doesn't feel right, while the attr is part of a request
it's not the request itself, so it seems cleaner to call it "obj".
Example:
static inline void
netdev_queue_id_set_id(struct netdev_queue_id *obj, __u32 id)
{
obj->_present.id = 1;
obj->id = id;
}

In general YNL provides allocation and free helpers for types.
For pure nested structs which are used as multi-attr (and therefore
have to be allocated dynamically) we already print a free helper
as it's needed by free of the containing struct.
Add printing of the alloc helper for consistency. The helper
takes the number of entries to allocate as an argument, e.g.:
static inline struct netdev_queue_id *netdev_queue_id_alloc(unsigned int n)
{
return calloc(n, sizeof(struct netdev_queue_id));
}

Pull networking fixes from Paolo Abeni:
"Including fixes from can and xfrm.
The TI regression notified last week is actually on our net-next tree,
it does not affect 6.16.
We are investigating a virtio regression which is quite hard to
reproduce - currently only our CI sporadically hits it. Hopefully it
should not be critical, and I'm not sure that an additional week would
be enough to solve it.
Current release - fix to a fix:
- sched: sch_qfq: avoid sleeping in atomic context in qfq_delete_class
Previous releases - regressions:
- xfrm:
- set transport header to fix UDP GRO handling
- delete x->tunnel as we delete x
- eth:
- mlx5: fix memory leak in cmd_exec()
- i40e: when removing VF MAC filters, avoid losing PF-set MAC
- gve: fix stuck TX queue for DQ queue format
Previous releases - always broken:
- can: fix NULL pointer deref of struct can_priv::do_set_mode
- eth:
- ice: fix a null pointer dereference in ice_copy_and_init_pkg()
- ism: fix concurrency management in ism_cmd()
- dpaa2: fix device reference count leak in MAC endpoint handling
- icssg-prueth: fix buffer allocation for ICSSG
Misc:
- selftests: mptcp: increase code coverage"

The SMMU engine on HIP09 chip has a hardware issue.
SMMU pagetable prefetch features may prefetch and use a invalid PTE
even the PTE is valid at that time. This will cause the device trigger
fake pagefaults. The solution is to avoid prefetching by adding a
SYNC command when smmu mapping a iova. But the performance of nic has a
sharp drop. Then we do this workaround, always enable tx bounce buffer,
avoid mapping/unmapping on TX path.
This issue only affects HNS3, so we always enable
tx bounce buffer when smmu enabled to improve performance.

The s390x ISM device data sheet clearly states that only one
request-response sequence is allowable per ISM function at any point in
time. Unfortunately as of today the s390/ism driver in Linux does not
honor that requirement. This patch aims to rectify that.
This problem was discovered based on Aliaksei's bug report which states
that for certain workloads the ISM functions end up entering error state
(with PEC 2 as seen from the logs) after a while and as a consequence
connections handled by the respective function break, and for future
connection requests the ISM device is not considered -- given it is in a
dysfunctional state. During further debugging PEC 3A was observed as
well.
A kernel message like
[ 1211.244319] zpci: 061a:00:00.0: Event 0x2 reports an error for PCI function 0x61a
is a reliable indicator of the stated function entering error state
with PEC 2. Let me also point out that a kernel message like
[ 1211.244325] zpci: 061a:00:00.0: The ism driver bound to the device does not support error recovery
is a reliable indicator that the ISM function won't be auto-recovered
because the ISM driver currently lacks support for it.
On a technical level, without this synchronization, commands (inputs to
the FW) may be partially or fully overwritten (corrupted) by another CPU
trying to issue commands on the same function. There is hard evidence that
this can lead to DMB token values being used as DMB IOVAs, leading to
PEC 2 PCI events indicating invalid DMA. But this is only one of the
failure modes imaginable. In theory even completely losing one command
and executing another one twice and then trying to interpret the outputs
as if the command we intended to execute was actually executed and not
the other one is also possible. Frankly, I don't feel confident about
providing an exhaustive list of possible consequences.

This patch adds selftests to cover invalid narrower loads on the
context. These used to cause kernel warnings before the previous patch.
To trigger the warning, the load had to be aligned, to read an affected
context field (ex., skb->sk), and not starting at the beginning of the
field.
The nine new cases all fail without the previous patch.

The following BPF program, simplified from a syzkaller repro, causes a
kernel warning:
r0 = *(u8 *)(r1 + 169);
exit;
With pointer field sk being at offset 168 in __sk_buff. This access is
detected as a narrower read in bpf_skb_is_valid_access because it
doesn't match offsetof(struct __sk_buff, sk). It is therefore allowed
and later proceeds to bpf_convert_ctx_access. Note that for the
"is_narrower_load" case in the convert_ctx_accesses(), the insn->off
is aligned, so the cnt may not be 0 because it matches the
offsetof(struct __sk_buff, sk) in the bpf_convert_ctx_access. However,
the target_size stays 0 and the verifier errors with a kernel warning:
verifier bug: error during ctx access conversion(1)
This patch fixes that to return a proper "invalid bpf_context access
off=X size=Y" error on the load instruction.
The same issue affects multiple other fields in context structures that
allow narrow access. Some other non-affected fields (for sk_msg,
sk_lookup, and sockopt) were also changed to use bpf_ctx_range_ptr for
consistency.
Note this syzkaller crash was reported in the "Closes" link below, which
used to be about a different bug, fixed in
commit fce7bd8e385a ("bpf/verifier: Handle BPF_LOAD_ACQ instructions
in insn_def_regno()"). Because syzbot somehow confused the two bugs,
the new crash and repro didn't get reported to the mailing list.
