Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP

- Number of code moves to help the compiler with inlining. Avoid
output arguments for returning drop reason where possible

- Rework drop handling within qdiscs to include more metadata about
the reason and dropping qdisc in the tracepoints

- Remove the rtnl_lock use from IP Multicast Routing

- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two

- Report TCP delayed ack timer information via socket diag

- Add ip_local_port_step_width sysctl to allow distributing the
randomly selected ports more evenly throughout the allowed space

- Add support for per-route tunsrc in IPv6 segment routing

- Start work of switching sockopt handling to iov_iter

- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up

- Support MSG_EOR in MPTCP

- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage

- Remove UDP-Lite support (as announced in 2023)

- Remove support for building IPv6 as a module. Remove the now
unnecessary function calling indirection

Cross-tree stuff:

- Move Michael MIC code from generic crypto into wireless, it's
considered insecure but some WiFi networks still need it

Netfilter:

- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.

Florian W reports this gets us ~13% higher packet rate

- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex

- Add more opinionated input validation to lower security exposure

- Make IPVS hash tables to be per-netns and resizable

Wireless:

- Finished assoc frame encryption/EPPKE/802.1X-over-auth

- Radar detection improvements

- Add 6 GHz incumbent signal detection APIs

- Multi-link support for FILS, probe response templates and client
probing

- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware

Driver API:

- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs

- Add standard counters for reporting pause storm events (implement
in mlx5 and fbnic)

- Add configuration API for completion writeback buffering (implement
in mana)

- Support driver-initiated change of RSS context sizes

- Support DPLL monitoring input frequency (implement in zl3073x)

- Support per-port resources in devlink (implement in mlx5)

Misc:

- Expand the YAML spec for Netfilter

Merge branch 'convert-config_ipv6-to-built-in-and-remove-stubs'

Fernando Fernandez Mancera says:

====================
Convert CONFIG_IPV6 to built-in and remove stubs

Historically, the Linux kernel has supported compiling the IPv6 stack as
a loadable module. While this made sense in the early days of IPv6
adoption, modern deployments and distributions overwhelmingly either
build IPv6 directly into the kernel (CONFIG_IPV6=y) or disable it
entirely (CONFIG_IPV6=n). The modular IPv6 use-case offers image size
and memory savings for specific setups, this benefit is outweighed by
the architectural burden it imposes on the subsystems on implementation
and maintenance.

In addition, most of the distributions are already using CONFIG_IPV6=y
by default [1], including openWRT [2] and Android gki_defconfig [3]. So
this won't have an impact on them. The most impacted architecture would
probably be arm64 as their default config is still using CONFIG_IPV6=m.

To allow core networking, BPF, Netfilter, and various device drivers to
safely interact with a potentially unloaded IPv6 module, the kernel
relies on indirect call structures like ipv6_stub, ipv6_bpf_stub, and
nf_ipv6_ops, along with dynamic RCU registrations for things like ICMPv6
senders.

This patch series addresses this by changing CONFIG_IPV6 from a tristate
to a boolean, enforcing that IPv6 is either built-in or disabled. This
allows us to completely rip out the stub infrastructures and safely
replace them with direct function calls.

The bloat-o-meter report the following results for m68k, arm64, x86_64
defconfig.

m68k (keep on mind that CONFIG_IPV6 is disabled now):
add/remove: 65/938 grow/shrink: 36/254 up/down: 3022/-49692 (-46670)

arm64:
add/remove: 1251/265 grow/shrink: 81/46 up/down: 448740/-71519 (377221)

x86_64:
add/remove: 62/98 grow/shrink: 10/39 up/down: 2497/-4357 (-1860)

Considering that each new kernel release increases sizes by 30-40KiB on
average, this size increase isn't a huge jump for the distributions that
are still using CONFIG_IPV6=m. For the ones that are already using
CONFIG_IPV6=y, the size is reduced actually.

All the patches has been independently build tested. With allmodconfig
and allmodconfig + CONFIG_IPV6=n. In addition, net selftest has been run
against them on virtme-ng.

The series applied as a whole as been tested with allyesconfig and also
allyesconfig + CONFIG_IPV6=n but not all patches has been independently
tested this way.

ipv6: convert CONFIG_IPV6 to built-in only and clean up Kconfigs

Maintaining a modular IPv6 stack offers image size savings for specific
setups, this benefit is outweighed by the architectural burden it
imposes on the subsystems on implementation and maintenance. Therefore,
drop it.

Change CONFIG_IPV6 from tristate to bool. Remove all Kconfig
dependencies across the tree that explicitly checked for IPV6=m. In
addition, remove MODULE_DESCRIPTION(), MODULE_ALIAS(), MODULE_AUTHOR()
and MODULE_LICENSE().

This is also replacing module_init() by device_initcall(). It is not
possible to use fs_initcall() as IPv4 does because that creates a race
condition on IPv6 addrconf.

Finally, modify the default configs from CONFIG_IPV6=m to CONFIG_IPV6=y
except for m68k as according to the bloat-o-meter the image is
increasing by 330KB~ and that isn't acceptable. Instead, disable IPv6 on
this architecture by default. This is aligned with m68k RAM requirements
and recommendations [1].

Henrik Bjoernlund says:

====================
net: bridge: cfm: Add support for Connectivity Fault Management(CFM)

Connectivity Fault Management (CFM) is defined in 802.1Q
section 12.14.

Connectivity Fault Management (CFM) comprises capabilities for
detecting, verifying, and isolating connectivity failures in Virtual
Bridged Networks. These capabilities can be used in networks
operated by multiple independent organizations, each with restricted
management access to each other’s equipment.

CFM functions are partitioned as follows:
— Path discovery
— Fault detection
— Fault verification and isolation
— Fault notification
— Fault recovery

The primary CFM protocol shims are called Maintenance Points (MPs).
A MP can be either a MEP or a MHF.
The MEP:
-It is the Maintenance association End Point
described in 802.1Q section 19.2.
-It is created on a specific level (1-7) and is assuring
that no CFM frames are passing through this MEP on lower levels.
-It initiates and terminates/validates CFM frames on its level.
-It can only exist on a port that is related to a bridge.
The MHF:
-It is the Maintenance Domain Intermediate Point
(MIP) Half Function (MHF) described in 802.1Q section 19.3.
-It is created on a specific level (1-7).
-It is extracting/injecting certain CFM frame on this level.
-It can only exist on a port that is related to a bridge.
-Currently not supported.

There are defined the following CFM protocol functions:
-Continuity Check
-Loopback. Currently not supported.
-Linktrace. Currently not supported.

This CFM component supports create/delete of MEP instances and
configuration of the different CFM protocols. Also status information
can be fetched and delivered through notification due to defect
status change.

The user interacts with CFM using the 'cfm' user space client
program, the client talks with the kernel using netlink.

Any notification emitted by CFM from the kernel can be monitored in
user space by starting 'cfm_server' program.

Currently this 'cfm' and 'cfm_server' programs are standalone placed
in a cfm repository https://github.com/microchip-ung/cfm but it is
considered to integrate this into 'iproute2'.

v1 -> v2
Added the CFM switchdev interface and also added utilization by
calling the interface from the kernel CFM implementation trying
to offload CFM functionality to HW. This offload (CFM driver) is
currently not implemented.

Corrections based on RCF comments:
-The single CFM kernel implementation Patch is broken up into
three patches.
-Changed the list of MEP instances from list_head to
hlist_head.
-Removed unnecessary RCU list traversing.
-Solved RCU unlocking problem.
-Removed unnecessary comments.
-Added ASSERT_RTNL() where required.
-Shaping up on error messages.
-Correction NETLINK br_fill_ifinfo() to be able to handle
'filter_mask' with multiple flags asserted.

v2 -> v3
-The switchdev definition and utilization has been removed as
there was no switchdev implementation.
-Some compiling issues are fixed as Reported-by:
kernel test robot <lkp@intel.com>.

v3 -> v4
-Fixed potential crash during hlist walk where elements are
removed.
-Giving all commits unique titles.
-NETLINK implementation split into three commits.
-Commit "bridge: cfm: Bridge port remove" is merged with
commit "bridge: cfm: Kernel space implementation of CFM. MEP
create/delete."

v4 -> v5
-Reordered members in struct net_bridge to bring member
frame_type_list to the first cache line.
-Helper functions nla_get_mac() and nla_get_maid() are removed.
-The NLA_POLICY_NESTED() macro is used to initialize the
br_cfm_policy array.
-Fixed reverse xmas tree.

v5 -> v6
-Fixed that the SKB buffer was not freed during error handling return.
-Removed unused struct definition.
-Changed bool to u8 bitfields for space save.
-Utilizing the NETLINK policy validation feature.

v6 -> v7
-Removed check of parameters in br_cfm_mep_config_set() and
br_cfm_cc_peer_mep_add() in first commit of MEP implementation
(Patch 4 out of 10)
