netfilter updates for net-next
This pull request contains changes for the *net-next* tree.
1. Change IPv6 stack to keep conntrack references until ipsec policy
checks are done, like ipv4, from Madhu Koriginja.
This update was missed when IPv6 NAT support was added 10 years ago.
2. get rid of old 'compat' structure layout in nf_nat_redirect
core and move the conversion to the only user that needs the
old layout for abi reasons. From Jeremy Sowden.
3. Compact some common code paths in nft_redir, also from Jeremy.
4. Time to remove the 'default y' knob so iptables 32bit compat interface
isn't compiled in by default anymore, from myself.
5. Move ip(6)tables builtin icmp matches to the udptcp one.
This has the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used.
Also from myself.
* 'main' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next:
netfilter: keep conntrack reference until IPsecv6 policy checks are done
xtables: move icmp/icmpv6 logic to xt_tcpudp
netfilter: xtables: disable 32bit compat interface by default
netfilter: nft_masq: deduplicate eval call-backs
netfilter: nft_redir: use `struct nf_nat_range2` throughout and deduplicate eval call-backs

When requesting a TX queue at a given index, warn on out-of-bounds
referencing if the index is greater than the allocated number of
queues.
Specifically, since this function is used heavily in the networking
stack use DEBUG_NET_WARN_ON_ONCE to avoid executing a new branch on
every packet.

The following patches are an outcome of Raed's work to add packet
offload support to libreswan [1].
The series includes:
* Priority support to IPsec policies
* Statistics per-SA (visible through "ip -s xfrm state ..." command)
* Support to IKE policy holes
* Fine tuning to acquire logic.

`nf_nat_redirect_ipv4` takes a `struct nf_nat_ipv4_multi_range_compat`,
but converts it internally to a `struct nf_nat_range2`. Change the
function to take the latter, factor out the code now shared with
`nf_nat_redirect_ipv6`, move the conversion to the xt_REDIRECT module,
and update the ipv4 range initialization in the nft_redir module.
Replace a bare hex constant for 127.0.0.1 with a macro.
Remove `WARN_ON`. `nf_nat_setup_info` calls `nf_ct_is_confirmed`:
/* Can't setup nat info for confirmed ct. */
if (nf_ct_is_confirmed(ct))
return NF_ACCEPT;
This means that `ct` cannot be null or the kernel will crash, and
implies that `ctinfo` is `IP_CT_NEW` or `IP_CT_RELATED`.
nft_redir has separate ipv4 and ipv6 call-backs which share much of
their code, and an inet one switch containing a switch that calls one of
the others based on the family of the packet. Merge the ipv4 and ipv6
ones into the inet one in order to get rid of the duplicate code.
Const-qualify the `priv` pointer since we don't need to write through
it.
Assign `priv->flags` to the range instead of OR-ing it in.
Set the `NF_NAT_RANGE_PROTO_SPECIFIED` flag once during init, rather
than on every eval.

The SGMII core found in several MediaTek SoCs is identical to what can
also be found in MediaTek's MT7531 Ethernet switch IC.
As this has not always been clear, both drivers developed different
implementations to deal with the PCS.
Recently Alexander Couzens pointed out this fact which lead to the
development of this shared driver.
Add a dedicated driver, mostly by copying the code now found in the
Ethernet driver. The now redundant code will be removed by a follow-up
commit.

The Amlogic Meson internal PHY's have the same register layout as
certain SMSC PHY's (also for non-c22-standard registers). This seems
to be more than just coincidence. Apparently they also need the same
workaround for EDPD mode (energy detect power down). Therefore let's
export SMSC PHY driver functionality for use by the meson-gxl PHY

During XFRM acquire flow, a default SA is created to be updated later,
once acquire netlink message is handled in user space. When the relevant
policy is offloaded this default SA is also offloaded to IPsec offload
supporting driver, however this SA does not have context suitable for
offloading in HW, nor is interesting to offload to HW, consequently needs
a special driver handling apart from other offloaded SA(s).
Add a special flag that marks such SA so driver can handle it correctly.

We can change tcp_sk() to propagate its argument const qualifier,
thanks to container_of_const().
We have two places where a const sock pointer has to be upgraded
to a write one. We have been using const qualifier for lockless
listeners to clearly identify points where writes could happen.
Add tcp_sk_rw() helper to better document these.
tcp_inbound_md5_hash(), __tcp_grow_window(), tcp_reset_check()
and tcp_rack_reo_wnd() get an additional const qualififer
for their @tp local variables.
smc_check_reset_syn_req() also needs a similar change.

wwan_port_fops_write inputs the SKB parameter to the TX callback of
the WWAN device driver. However, the WWAN device (e.g., t7xx) may
have an MTU less than the size of SKB, causing the TX buffer to be
sliced and copied once more in the WWAN device driver.
This patch implements the slicing in the WWAN subsystem and gives
the WWAN devices driver the option to slice(by frag_len) or not. By
doing so, the additional memory copy is reduced.
Meanwhile, this patch gives WWAN devices driver the option to reserve
headroom in fragments for the device-specific metadata.

KVM_HC_CLOCK_PAIRING currently fails inside SEV-SNP guests because the
guest passes an address to static data to the host. In confidential
computing the host can't access arbitrary guest memory so handling the
hypercall runs into an "rmpfault". To make the hypercall work, the guest
needs to explicitly mark the memory as decrypted. Do that in
kvm_arch_ptp_init(), but retain the previous behavior for
non-confidential guests to save us from having to allocate memory.
Add a new arch-specific function (kvm_arch_ptp_exit()) to free the
allocation and mark the memory as encrypted again.

Add an internal flag to indicate whether MDB entries are configured or
not. Set the flag after installing the first MDB entry and clear it
before deleting the last one.
The flag will be consulted by the data path which will only perform an
MDB lookup if the flag is set, thereby keeping the MDB overhead to a
minimum when the MDB is not used.
Another option would have been to use a static key, but it is global and
not per-device, unlike the current approach.

Implement MDB control path support, enabling the creation, deletion,
replacement and dumping of MDB entries in a similar fashion to the
bridge driver. Unlike the bridge driver, each entry stores a list of
remote VTEPs to which matched packets need to be replicated to and not a
list of bridge ports.
The motivating use case is the installation of MDB entries by a user
space control plane in response to received EVPN routes. As such, only
allow permanent MDB entries to be installed and do not implement
snooping functionality, avoiding a lot of unnecessary complexity.
Since entries can only be modified by user space under RTNL, use RTNL as
the write lock. Use RCU to ensure that MDB entries and remotes are not
freed while being accessed from the data path during transmission.
In terms of uAPI, reuse the existing MDB netlink interface, but add a
few new attributes to request and response messages:
* IP address of the destination VXLAN tunnel endpoint where the
multicast receivers reside.
* UDP destination port number to use to connect to the remote VXLAN
tunnel endpoint.
* VXLAN VNI Network Identifier to use to connect to the remote VXLAN
tunnel endpoint. Required when Ingress Replication (IR) is used and
the remote VTEP is not a member of originating broadcast domain
(VLAN/VNI) [1].
* Source VNI Network Identifier the MDB entry belongs to. Used only when
the VXLAN device is in external mode.
* Interface index of the outgoing interface to reach the remote VXLAN
tunnel endpoint. This is required when the underlay destination IP is
multicast (P2MP), as the multicast routing tables are not consulted.
All the new attributes are added under the 'MDBA_SET_ENTRY_ATTRS' nest
which is strictly validated by the bridge driver, thereby automatically
rejecting the new attributes.

In my previous commit 0349b8779c ("sched: add new attr TCA_EXT_WARN_MSG
to report tc extact message") I didn't notice the tc action use different
enum with filter. So we can't use TCA_EXT_WARN_MSG directly for tc action.
Let's add a TCA_ROOT_EXT_WARN_MSG for tc action specifically and put this
param before going to the TCA_ACT_TAB nest.

I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but
we still put a slightly different license on the uAPI header
than the rest of the code. Use the Linux-syscall-note on all
the specs and all generated code. It's moot for kernel code,
