Move the timeout/expire/flag members from nft_trans_one_elem struct into
a dybamically allocated structure, only needed when timeout update was
requested.
This halves size of nft_trans_one_elem struct and allows to compact up to
124 elements in one transaction container rather than 62.
This halves memory requirements for a large flush or insert transaction,
where ->update remains NULL.
Care has to be taken to release the extra data in all spots, including
abort path.

Add helpers to release the individual elements contained in the
trans_elem container structure.
No functional change intended.
Followup patch will add 'nelems' member and will turn 'priv' into
a flexible array.
These helpers can then loop over all elements.
Care needs to be taken to handle a mix of new elements and existing
elements that are being updated (e.g. timeout refresh).
Before this patch, NEWSETELEM transaction with update is released
early so nft_trans_set_elem_destroy() won't get called, so we need
to skip elements marked as update.

Commit 4598380f9c54 ("bonding: fix ns validation on backup slaves")
tried to resolve the issue where backup slaves couldn't be brought up when
receiving IPv6 Neighbor Solicitation (NS) messages. However, this fix only
worked for drivers that receive all multicast messages, such as the veth
interface.
For standard drivers, the NS multicast message is silently dropped because
the slave device is not a member of the NS target multicast group.
To address this, we need to make the slave device join the NS target
multicast group, ensuring it can receive these IPv6 NS messages to validate
the slave’s status properly.
There are three policies before joining the multicast group:
1. All settings must be under active-backup mode (alb and tlb do not support
arp_validate), with backup slaves and slaves supporting multicast.
2. We can add or remove multicast groups when arp_validate changes.
3. Other operations, such as enslaving, releasing, or setting NS targets,
need to be guarded by arp_validate.

In this commit, we make fib_validate_source() and __fib_validate_source()
return -reason instead of errno on error.
The return value of fib_validate_source can be -errno, 0, and 1. It's hard
to make fib_validate_source() return drop reasons directly.
The fib_validate_source() will return 1 if the scope of the source(revert)
route is HOST. And the __mkroute_input() will mark the skb with
IPSKB_DOREDIRECT in this case (combine with some other conditions). And
then, a REDIRECT ICMP will be sent in ip_forward() if this flag exists. We
can't pass this information to __mkroute_input if we make
fib_validate_source() return drop reasons.
Therefore, we introduce the wrapper fib_validate_source_reason() for
fib_validate_source(), which will return the drop reasons on error.
In the origin logic, LINUX_MIB_IPRPFILTER will be counted if
fib_validate_source() return -EXDEV. And now, we need to adjust it by
checking "reason == SKB_DROP_REASON_IP_RPFILTER". However, this will take
effect only after the patch "net: ip: make ip_route_input_noref() return
drop reasons", as we can't pass the drop reasons from
fib_validate_source() to ip_rcv_finish_core() in this patch.
Following new drop reasons are added in this patch:
SKB_DROP_REASON_IP_LOCAL_SOURCE
SKB_DROP_REASON_IP_INVALID_SOURCE

RTNL_FLAG_DOIT_PERNET_WIP.
Currently, rtnl_setlink() and rtnl_dellink() cannot be fully converted
to per-netns RTNL due to a lack of handling peer/lower/upper devices in
different netns.
For example, when we change a device in rtnl_setlink() and need to
propagate that to its upper devices, we want to avoid acquiring all netns
locks, for which we do not know the upper limit.
The same situation happens when we remove a device.
rtnl_dellink() could be transformed to remove a single device in the
requested netns and delegate other devices to per-netns work, and
rtnl_setlink() might be ?
Until we come up with a better idea, let's use a new flag
RTNL_FLAG_DOIT_PERNET_WIP for rtnl_dellink() and rtnl_setlink().
This will unblock converting RTNL users where such devices are not related.

In ops->newlink(), veth, vxcan, and netkit call rtnl_link_get_net() with
a net pointer, which is the first argument of ->newlink().
rtnl_link_get_net() could return another netns based on IFLA_NET_NS_PID
and IFLA_NET_NS_FD in the peer device's attributes.
We want to get it and fill rtnl_nets->nets[] in advance in rtnl_newlink()
for per-netns RTNL.
All of the three get the peer netns in the same way:
1. Call rtnl_nla_parse_ifinfomsg()
2. Call ops->validate() (vxcan doesn't have)
3. Call rtnl_link_get_net_tb()
Let's add a new field peer_type to struct rtnl_link_ops and prefetch
netns in the peer ifla to add it to rtnl_nets in rtnl_newlink().

link_ops is protected by link_ops_mutex and no longer needs RTNL,
so we have no reason to have __rtnl_link_register() separately.
Let's remove it and call rtnl_link_register() from ifb.ko and

Note that both modules' init() work on init_net only, so we need
not export pernet_ops_rwsem and can use rtnl_net_lock() there.

rtnl_link_unregister() holds RTNL and calls synchronize_srcu(),
but rtnl_newlink() will acquire SRCU frist and then RTNL.
Then, we need to unlink ops and call synchronize_srcu() outside
of RTNL to avoid the deadlock.
rtnl_link_unregister() rtnl_newlink()

lock(rtnl_mutex);
lock(&ops->srcu);
lock(rtnl_mutex);

Let's move as such and add a mutex to protect link_ops.
Now, link_ops is protected by its dedicated mutex and
rtnl_link_register() no longer needs to hold RTNL.
While at it, we move the initialisation of ops->dellink and
ops->srcu out of the mutex scope.

rtnl_link_unregister() holds RTNL and calls __rtnl_link_unregister(),
where we call synchronize_srcu() to wait inflight RTM_NEWLINK requests
for per-netns RTNL.
We put synchronize_srcu() in __rtnl_link_unregister() due to ifb.ko

However, rtnl_newlink() will acquire SRCU before RTNL later in this
series. Then, lockdep will detect the deadlock:
rtnl_link_unregister() rtnl_newlink()

lock(rtnl_mutex);
lock(&ops->srcu);

To avoid the problem, we must call synchronize_srcu() before RTNL in
rtnl_link_unregister().
As a preparation, let's remove __rtnl_link_unregister().

MCTP control protocol implementations are transport binding dependent.
Endpoint discovery is mandatory based on transport binding.
Message timing requirements are specified in each respective transport
binding specification.
However, we currently have no means to get this information from MCTP
links.
Add a IFLA_MCTP_PHYS_BINDING netlink link attribute, which represents
the transport type using the DMTF DSP0239-defined type numbers, returned
as part of RTM_GETLINK data.
We get an IFLA_MCTP_PHYS_BINDING attribute for each MCTP link, for
example:
- 0x00 (unspec) for loopback interface;
- 0x01 (SMBus/I2C) for mctpi2c%d interfaces; and
- 0x05 (serial) for mctpserial%d interfaces.

Convert the "tos" parameter of ip_route_output() to dscp_t. This way
we'll have a dscp_t value directly available when .flowi4_tos will
eventually be converted to dscp_t.
All ip_route_output() callers but one set this "tos" parameter to 0 and
therefore don't need to be adapted to the new prototype.
Only br_nf_pre_routing_finish() needs conversion. It can just use
ip4h_dscp() to get the DSCP field from the IPv4 header.

4) Use nft_trans_elem_alloc() in catchall flush, from Florian Westphal.
5) A series of 7 patches to fix false positive with CONFIG_RCU_LIST=y.
Florian also sees possible issue with 10 while module load/removal
when requesting an expression that is available via module. As for
patch 11, object is being updated so reference on the module already
exists so I don't see any real issue.
Florian says:
"Unfortunately there are many more errors, and not all are false positives.
First patches pass lockdep_commit_lock_is_held() to the rcu list traversal
macro so that those splats are avoided.
The last two patches are real code change as opposed to
'pass the transaction mutex to relax rcu check':
Those two lists are not protected by transaction mutex so could be altered
in parallel.
This targets nf-next because these are long-standing issues."

8c873e219970 ("netfilter: core: free hooks with call_rcu") removed
synchronize_net() call when unregistering basechain hook, however,
net_device removal event handler for the NFPROTO_NETDEV was not updated
to wait for RCU grace period.
Note that 835b803377f5 ("netfilter: nf_tables_netdev: unregister hooks
on net_device removal") does not remove basechain rules on device
removal, I was hinted to remove rules on net_device removal later, see
5ebe0b0eec9d ("netfilter: nf_tables: destroy basechain and rules on
netdevice removal").
Although NETDEV_UNREGISTER event is guaranteed to be handled after
synchronize_net() call, this path needs to wait for rcu grace period via
rcu callback to release basechain hooks if netns is alive because an
ongoing netlink dump could be in progress (sockets hold a reference on
the netns).
Note that nf_tables_pre_exit_net() unregisters and releases basechain
hooks but it is possible to see NETDEV_UNREGISTER at a later stage in
the netns exit path, eg. veth peer device in another netns:
cleanup_net()
default_device_exit_batch()
unregister_netdevice_many_notify()
notifier_call_chain()
nf_tables_netdev_event()
__nft_release_basechain()
In this particular case, same rule of thumb applies: if netns is alive,
then wait for rcu grace period because netlink dump in the other netns
could be in progress. Otherwise, if the other netns is going away then
no netlink dump can be in progress and basechain hooks can be released
inmediately.
While at it, turn WARN_ON() into WARN_ON_ONCE() for the basechain
validation, which should not ever happen.

Add a 20-byte field ats to struct nfc_target and expose it as
NFC_ATTR_TARGET_ATS via the netlink interface. The payload contains
'historical bytes' that help to distinguish cards from one another.
The information is commonly used to assemble an emulated ATR similar
to that reported by smart cards with contacts.
Add a 20-byte field target_ats to struct nci_dev to hold the payload
obtained in nci_rf_intf_activated_ntf_packet() and copy it to over to
nfc_target.ats in nci_activate_target(). The approach is similar
to the handling of 'general bytes' within ATR_RES.
Replace the hard-coded size of rats_res within struct
activation_params_nfca_poll_iso_dep by the equal constant NFC_ATS_MAXSIZE
now defined in nfc.h
Within NCI, the information corresponds to the 'RATS Response' activation
parameter that omits the initial length byte TL. This loses no
information and is consistent with our handling of SENSB_RES that
also drops the first (constant) byte.
Tested with nxp_nci_i2c on a few type A targets including an
ICAO 9303 compliant passport.
I refrain from the corresponding change to digital_in_recv_ats()
to have the few drivers based on digital.h fill nfc_target.ats,
as I have no way to test it. That class of drivers appear not to set
NFC_ATTR_TARGET_SENSB_RES either. Consider a separate patch to propagate
(all) the parameters.

As the introduction of the support for vsock and unix sockets in sockmap,
tls_sw_has_ctx_tx/rx cannot presume the socket passed in must be IS_ICSK.
vsock and af_unix sockets have vsock_sock and unix_sock instead of
inet_connection_sock. For these sockets, tls_get_ctx may return an invalid
pointer and cause page fault in function tls_sw_ctx_rx.

Under CONFIG_PROVE_RCU_LIST + CONFIG_RCU_EXPERT
hlist_for_each_entry_rcu() provides very helpful splats, which help
to find possible issues. I missed CONFIG_RCU_EXPERT=y in my testing
config the same as described in
a3e4bf7f9675 ("configs/debug: make sure PROVE_RCU_LIST=y takes effect").
The fix itself is trivial: add the very same lockdep annotations
as were used to dereference ao_info from the socket.

Background: switchdev ports offload the Linux bridge, and most of the
packets they handle will never see the CPU. The ports between which
there exists no hardware data path are considered 'foreign' to switchdev.
These can either be normal physical NICs without switchdev offload, or
incompatible switchdev ports, or virtual interfaces like veth/dummy/etc.
In some cases, an offloaded filter can only do half the work, and the
rest must be handled by software. Redirecting/mirroring from the ingress
of a switchdev port towards a foreign interface is one example of
combined hardware/software data path. The most that the switchdev port
can do is to extract the matching packets from its offloaded data path
and send them to the CPU. From there on, the software filter runs
(a second time, after the first run in hardware) on the packet and
performs the mirred action.
It makes sense for switchdev drivers which allow this kind of "half
offloading" to sense the "skip_sw" flag of the filter/action pair, and
deny attempts from the user to install a filter that does not run in
software, because that simply won't work.
In fact, a mirred action on a switchdev port towards a dummy interface
appears to be a valid way of (selectively) monitoring offloaded traffic
that flows through it. IFF_PROMISC was also discussed years ago, but
(despite initial disagreement) there seems to be consensus that this
flag should not affect the destination taken by packets, but merely
whether or not the NIC discards packets with unknown MAC DA for local
processing.

====================
wireless-next patches for v6.13
The first -next "new features" pull request for v6.13. This is a big
one as we have not been able to send one earlier. We have also some
patches affecting other subsystems: in staging we deleted the rtl8192e
driver and in debugfs added a new interface to save struct
file_operations memory; both were acked by GregKH.
Because of the lib80211/libipw move there were quite a lot of
conflicts and to solve those we decided to merge net-next into
wireless-next.
Major changes:
cfg80211/mac80211
* stop exporting wext symbols
* new mac80211 op to indicate that a new interface is to be added
* support radio separation of multi-band devices
Wireless Extensions
* move wext spy implementation to libiw
* remove iw_public_data from struct net_device
brcmfmac
* optional LPO clock support
ipw2x00
* move remaining lib80211 code into libiw
