amt does not need to access struct socket itself in the fast path;
it only reads struct sock, and struct socket is only used for tunnel
setup and teardown.
Let's store struct sock directly in struct amt.
amt_dev_stop() is called as dev->netdev_ops->ndo_stop().
synchronize_net() in unregister_netdevice_many_notify() ensures
that inflight amt RX fast paths finish before amt_dev is freed.
amt no longer needs synchronize_rcu() in udp_tunnel_sock_release().
Note that amt_dev_stop() looks buggy; cancel_delayed_work_sync()
should be called after udp_tunnel_sock_release().

We will remove synchronize_rcu() in udp_tunnel_sock_release().
We must ensure that vxlan_sock is freed after inflight RX fast path.
Let's free vxlan_sock with kfree_rcu().
Note that vxlan_sock.vni_list[] is 8K and struct rcu_head must
be placed before it.

Commit 3cf7203ca6 ("net/tunnel: wait until all sk_user_data
reader finish before releasing the sock") added synchronize_rcu()
in udp_tunnel_sock_release().
This was intended to protect the fast path of a dying vxlan device
from dereferencing vxlan_sock->sock->sk after sock_orphan() has set
sock->sk to NULL.
However, vxlan does not need to access struct socket itself in the
fast path; it only reads struct sock, and struct socket is only
used for tunnel setup and teardown.
Let's store struct sock directly in struct vxlan_sock.
In the next patch, we will free vxlan_sock with kfree_rcu(), then
vxlan no longer needs synchronize_rcu() in udp_tunnel_sock_release().

None of the udp_tunnel users need struct socket in their
fast paths; it is only used for tunnel setup / teardown.
While the UDP tunnel interface accepts struct socket, this
encourages users to store the pointer unnecessarily. This
leads to extra dereferences when accessing struct sock fields
(e.g., sk->sk_user_data instead of sock->sk->sk_user_data).
Furthermore, these dereferences necessitate synchronize_rcu()
in udp_tunnel_sock_release() to protect the fast paths from
sock_orphan() setting sk->sk_socket to NULL.
This overhead can be avoided if users store the struct sock
pointer directly in their private structures.
As a prep, let's change udp_tunnel_sock_release() to take
struct sock instead of struct socket.

In MLD, MRC and QQIC fields are not correctly encoded when
generating query packets. Since the receiver of the query
interprets these fields using the MLDv2 floating-point
decoding logic, any value that exceeds the linear threshold
is incorrectly parsed as an exponential value, leading to
an incorrect interval calculation.
Encode and assign the corresponding protocol fields during
query generation. Introduce the logic to dynamically
calculate the exponent and mantissa using bit-scan (fls).
This ensures MRC (16-bit) and QQIC (8-bit) fields are
properly encoded when transmitting query packets with
intervals that exceed their respective linear thresholds
(32768 for MRD; 128 for QQI).

Response Code field represents a floating-point value as

The cs89x0 driver is really two in one, and they are mutually exclusive:
- the ISA driver was used on 486-era PCs. It likely has no remaining
users, like the other ethernet drivers that got removed in
linux-7.1. The DMA support in here is the last device driver use of
the deprecated isa_bus_to_virt() interface, all other users are either
x86 specific or or got converted to the normal dma-mapping interface.
The driver was maintained by Andrew Morton at the time, based on
the linux-2.2 vendor driver from Cirrus Logic.
- the platform_driver instance was used on some embedded Arm boards
around the same time, such as the EP7211 Development Kit. This
is the same chip, but uses modern devicetree based probing and no DMA.
This was added by Alexander Shiyan.
Remove the ISA driver as a cleanup, including all of the outdated
documentation referring to its configuration.

Currently the kernel's TCP-AO implementation does the MAC and KDF
computations using the crypto_ahash API. This API is inefficient and
difficult to use, and it has required extensive workarounds in the form
of per-CPU preallocated objects (tcp_sigpool) to work at all.
Let's use lib/crypto/ instead. This means switching to straightforward
stack-allocated structures, virtually addressed buffers, and direct
function calls. It also means removing quite a bit of error handling.
This makes TCP-AO quite a bit faster.
This also enables many additional cleanups, which later commits will
handle: removing tcp-sigpool, removing support for crypto_tfm cloning,
removing more error handling, and replacing more dynamically-allocated
buffers with stack buffers based on the now-statically-known limits.

Commit db359fccf2 ("mm: introduce a new page type for page pool in
page type") added a page_type field to struct net_iov at the same
offset as struct page::page_type, so that page_pool_set_pp_info() can
call __SetPageNetpp() uniformly on both pages and net_iovs.
The page-type API requires the field to hold the UINT_MAX "no type"
sentinel before a type can be set; for real struct page that invariant
is established by the page allocator on free. struct net_iov is not
allocated through the page allocator, so the field is left as zero
(io_uring zcrx, which uses __GFP_ZERO) or as slab garbage (devmem,
which uses kvmalloc_objs() without zeroing). When the page pool then
calls page_pool_set_pp_info() on a freshly-bound niov,
__SetPageNetpp()'s VM_BUG_ON_PAGE(page->page_type != UINT_MAX) fires
and the kernel BUGs. Triggered in selftests by io_uring zcrx setup
through the fbnic queue restart path:

Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) IEEE1394 ARP payload contains no target hardware address in the
ARP packet. Apparently, arp_tables was never updated to deal with
IEEE1394 ARP properly. To deal with this, return no match in case
the target hardware address selector is used, either for inverse or
normal match. Moreover, arpt_mangle disallows mangling of the target
hardware and IP address because, it is not worth to adjust the
offset calculation to fix this, we suspect no users of arp_tables
for this family.
2) Use list_del_rcu() to delete device hooks in nf_tables, this hook
list is RCU protected, concurrent netlink dump readers can be
walking on this list, fix it by adding a helper function and use it
for consistency. From Florian Westphal.
3) Add list_splice_rcu(), this is useful for joining the local list of
new device hooks to the RCU protected hook list in chain and
flowtable. Reviewed by Paul E. McKenney.
4) Use list_splice_rcu() to publish the new device hooks in chain and
flowtable to fix concurrent netlink dump traversal.
5) Add a new hook transaction object to track device hook deletions.
The current approach moves device hooks to be deleted around during
the preparation phase, this breaks concurrent RCU reader via netlink
dump. This new hook transaction is combined with NFT_HOOK_REMOVE
flag to annotate hooks for removal in the preparation phase.
6) xt_policy inbound policy check in strict mode can lead to
out-of-bound access of the secpath array due to incorrect.
The iteration over the secpath needs to be reversed in the inbound
to check for the human readable policy, expecting inner in first
position and outer in second position, the secpath from inbound
actually stores outer in first position then in second position.
From Jiexun Wang.
7) Fix possible zero shift in nft_bitwise triggering UBSAN splat,
reject zero shift from control plane, from Kai Ma.
8) Replace simple_strtoul() in the conntrack SIP helper since it relies
on nul-terminated strings. From Florian Westphal.

The HT/VHT/HE/EHT/UHR operation can change, and might thus be
updated on each beacon update. Move them to the beacon struct
and parse them out of the beacon also on updates, not just on
starting the AP.
This also fixes checks in two ways:
- Regulatory checks in nl80211_validate_ap_phy_operation() are
now done also on updates, disallowing enabling HE/EHT/UHR on
channels that don't allow that after start. This checks only
operation now, but clients can't use it without operation.
- NL80211_ATTR_UHR_OPERATION is now required whenever UHR is
present in the beacon, and rejected otherwise.

someone wanted the code to stay. It is never very clear to me how many
of those people actually use the code vs are just nostalgic to see it
go. Amateur radio did have occasional users (or so I think) but most
users switched to user space implementations since its all super slow

Remove the amateur radio (AX.25, NET/ROM, ROSE) protocol implementation
and all associated hamradio device drivers from the kernel tree.
This set of protocols has long been a huge bug/syzbot magnet,
and since nobody stepped up to help us deal with the influx
of the AI-generated bug reports we need to move it out of tree
to protect our sanity.
The code is moved to an out-of-tree repo:
https://github.com/linux-netdev/mod-orphan
if it's cleaned up and reworked there we can accept it back.
Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP,
AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN)
so that the conditional integration code in arp.c and tun.c continues
to compile and work when the out-of-tree modules are loaded.

Remove CAIF (Communication CPU to Application CPU Interface), the
ST-Ericsson modem protocol. The subsystem has been orphaned since 2013.
The last meaningful changes from the maintainers were in March 2013:
a8c7687bf2 ("caif_virtio: Check that vringh_config is not null")
b2273be8d2 ("caif_virtio: Use vringh_notify_enable correctly")
0d2e1a2926 ("caif_virtio: Introduce caif over virtio")
Not-so-coincidentally, according to "the Internet" ST-Ericsson officially
shut down its modem joint venture in Aug 2013.
If anyone is using this code please yell!
In the 13 years since, the code has accumulated 200 non-merge commits,
of which 71 were cross-tree API changes, 21 carried Fixes: tags, and
the remaining ~110 were cleanups, doc conversions, treewide refactors,
and one partial removal (caif_hsi, ca75bcf0a8).
We are still getting fixes to this code, in the last 10 days there were
3 reports on security@ about CAIF that I have been CCed on.
UAPI constants (AF_CAIF, ARPHRD_CAIF, N_CAIF, VIRTIO_ID_CAIF) and the
SELinux classmap entry are intentionally kept for ABI stability.

pie_dump_stats() only runs with RTNL held,
reading fields that can be changed in qdisc fast path.
Add READ_ONCE()/WRITE_ONCE() annotations.
Alternative would be to acquire the qdisc spinlock, but our long-term
goal is to make qdisc dump operations lockless as much as we can.
tc_pie_xstats fields don't need to be latched atomically,
otherwise this bug would have been caught earlier.

Restore the flag that indicates that the hook is going away, ie.
NFT_HOOK_REMOVE, but add a new transaction object to track deletion
of hooks without altering the basechain/flowtable hook_list during
the preparation phase.
The existing approach that moves the hook from the basechain/flowtable
hook_list to transaction hook_list breaks netlink dump path readers
of this RCU-protected list.
It should be possible use an array for nft_trans_hook to store the
deleted hooks to compact the representation but I am not expecting
many hook object, specially now that wildcard support for devices
is in place.
Note that the nft_trans_chain_hooks() list contains a list of struct
nft_trans_hook objects for DELCHAIN and DELFLOWTABLE commands, while
this list stores struct nft_hook objects for NEWCHAIN and NEWFLOWTABLE.
Note that new commands can be updated to use nft_trans_hook for
consistency.
This patch also adapts the event notification path to deal with the list
of hook transactions.

From the MCTP Base specification (DSP0236 v1.2.1), the first byte of
the MCTP header contains a 4 bit reserved field, and 4 bit version.
On our current receive path, we require those 4 reserved bits to be
zero, but the 9500-8i card is non-conformant, and may set these
reserved bits.
DSP0236 states that the reserved bits must be written as zero, and
ignored when read. While the device might not conform to the former,
we should accept these message to conform to the latter.
Relax our check on the MCTP version byte to allow non-zero bits in the
reserved field.

tcp_get_timestamping_opt_stats() does not own the socket lock,
this is intentional.
It calls tcp_get_info_chrono_stats() while other threads could
