Merge tag 'net-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

- Work on removing rtnl_lock protection throughout the stack
continues. In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal

- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.

- Support dumping qdiscs and page pools for a specific netdev. Even
tho user space wants a dump of all netdevs, most of the time, the
OOO programming model results in repeating the dump for each
netdev. Which, in absence of a cache, leads to a O(n^2) behavior.

- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.

- Rehash locally generated traffic to a different nexthop on
retransmit timeout.

- Honor oif when choosing nexthop for locally generated IPv6 traffic.

- Convert TCP Auth Option to crypto library, and drop non-RFC algos.

- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.

- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 >
40).

- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).

- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).

- Support binding GENEVE tunnels to a local address.

- Speed up UDP tunnel destruction (remove one synchronize_rcu()).

- Support exponential field encoding in multicast (IGMPv3 and MLDv2).

- Support attaching PSP crypto offload to containers (veth, netkit).

- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.

The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot
express reqid changes or migrate Transport mode selectors.

The new interface identifies the SA via SPI and mark, supports
reqid changes, address family changes, encap removal, and uses an
atomic create+install flow under x->lock to prevent SN/IV reuse
during AEAD SA migration.

- Implement GRO/GSO support for PPPoE.

- Convert sockopt callbacks in a number of protocols to iov_iter.

Cross-tree stuff:

- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto
API users, since it changed crypto transformation objects into
reference-counted objects.

- Add FCrypt-PCBC implementation to rxrpc and remove it from the
global crypto API as obsolete and insecure.

Wireless:

- Major rework of station bandwidth handling, fixing issues with
lower capability than AP.

- Cleanups for EMLSR spec issues (drafts differed).

- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)

- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).

- Fine Timing Measurement ranging (i.e. distance measurement) APIs.

Netfilter:

- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.

- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.

Deletions:

- Remove TLS + sockmap integration. TLS wants to pin user pages to
avoid a copy, and sockmap wants to write to the input stream. More
work on this integration is clearly needed, and we can't find any
users (original author admitted that they never deployed it).

- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from the
vendor that added this are AWOL.

- Remove more ATM code, trying to leave behind only what PPPoATM
needs, AAL5 and br2684 with permanent circuits.

- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.

- Disable 32-bit x_tables compatibility (32bit binaries on 64bit
kernel) interface in user namespaces. To be deleted completely,
soon.

- Remove 5/10 MHz support from cfg80211/mac80211.

Drivers:

- Software:
- Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit)
- bonding: add knob to strictly follow 802.3ad for link state

- New drivers:
- Alibaba Elastic Ethernet Adaptor (cloud vNIC).
- NXP NETC switch within i.MX94.

- DPLL:
- Add operational state to pins (implement in zl3073x).
- Add generic DPLL type, for daisy-chaining DPLLs (implement in ice).

- Ethernet high-speed NICs:
- Huawei (hinic3):
- enhance tc flow offload support with queue selection,
tunnels
- nVidia/Mellanox:
- avoid over-copying payload to the skb's linear part (up to

- expose more per-queue stats over the standard API
- support additional, unprivileged PFs in the DPU
configuration
- support Socket Direct (multi-PF) with switchdev offloads
- add a pool / frag allocator for DMA mapped buffers for
control objects, save memory on systems with 64kB page size

Merge branch 'consolidate-fcrypt-and-pcbc-code-into-net-rxrpc'

Eric Biggers says:

====================
Consolidate FCrypt and PCBC code into net/rxrpc/

The FCrypt "block cipher" and the PCBC mode of operation are obsolete
and insecure. Since their only user is net/rxrpc/, they belong there,
not in the crypto API.

Therefore, this series removes these algorithms from the crypto API and
replaces them with local implementations in net/rxrpc/.

The local implementations are simpler too, as they avoid the crypto API
boilerplate.

I don't know how to test all the code in net/rxrpc/, but everything
should still work. I added a KUnit test for the crypto functions.

net/rxrpc: Reimplement DES-PCBC using DES library

Since the use of "pcbc(des)" in rxkad_decrypt_ticket() is the only
remaining user of the crypto API "pcbc" template, just implement
DES-PCBC by locally implementing PCBC mode on top of the DES library.
Note that only the decryption direction is needed.

This will allow support for the obsolete PCBC mode to be removed from
the crypto API.

net/rxrpc: Use local FCrypt-PCBC implementation

Use the local implementation of FCrypt-PCBC instead of the crypto API
one. This will allow the crypto API one to be removed. It also
simplifies the code quite a bit.

The local FCrypt-PCBC implementation is also significantly faster than
the crypto API one, since the crypto API one had a lot of overhead. For
example, benchmarking on an x86_64 CPU, I see that FCrypt-PCBC
decryption throughput improved from 83 MB/s to 157 MB/s.

(Meanwhile, AES-256-GCM decryption is 8064 MB/s on the same CPU.
Clearly, anyone looking for good performance, or anything that is
actually secure for that matter, needs to look elsewhere anyway.)

Add a local implementation of FCrypt-PCBC encryption and decryption.
This will be used instead of the crypto API one, allowing the crypto API
one to be removed. It will also simplify rxkad.c quite a bit.

A KUnit test is included. The FCrypt-PCBC test vectors are borrowed
from the existing ones in crypto/testmgr.h. Note that this adds the
first KUnit test for net/rxrpc/, which previously had no KUnit tests.

The FCrypt code is based on crypto/fcrypt.c, but I simplified it a bit.
The PCBC part is straightforward and I just wrote it from scratch.

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

object allocations by using fib6_lookup() + RCU.

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

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:

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

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].
