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.

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

- 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):

tunnels
- nVidia/Mellanox:
- avoid over-copying payload to the skb's linear part (up to
60% win for LRO on slow CPUs like ARM64 V2)
- 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
- take advantage of the ability to dynamically change RSS
table size, even when table is configured by the user
- increase the max RSS table size for even traffic
distribution

Merge tag 'nf-next-26-05-25' of https://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next

Florian Westphal says:

====================
netfilter: updates for net-next

The following patchset contains Netfilter fixes and small enhancements:

1) Disable 32-bit x_tables compatibility (32bit binaries on 64bit
kernel) interface in user namespaces. This is 'last warning'
before this is removed for good.

2) Add a configuration toggle for netfilter GCOV profiling. Provide
dedicated toggles for ipset and ipvs.

3) Remove modular support for nfnetlink and restrict it to built-in only.
From Pablo Neira Ayuso.

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

5) Use nf_ct_exp_net() in ctnetlink expectation dumps.
From Pratham Gupta.

6) Remove a dead conditional in nft_set_rbtree.

7) Fix conntrack helper policy updates to apply per-class values correctly.
From David Carlier.

8) Fix an off-by-one OOB read in nf_conntrack_irc:parse_dcc(). Use strict
less-than comparison in the newline search loop to respect the
exclusive-end pointer convention. From Muhammad Bilal.

9) Fix typos in nf_conntrack_proto_tcp comments. From Avinash Duduskar.

10) Restore performance optimization in nft_set_pipapo_avx2 by passing
the next map index. Refactor lookup logic for clarity and add a
DEBUG_NET check to document this.

11) Avoid (harmless) u16 overflow in nf_conntrack_ftp when parsing FTP PORT
and EPRT commands. Ignore commands where single octet exceeds 255.
From Giuseppe Caruso.

Patch 12, which removes incorrect (and obviously unused) code from
nft_byteorder was kept back to avoid a net -> net-next merge conflict.

====================
Reimplement TCP-AO using crypto library

This series can also be retrieved from:

git fetch https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git tcp-ao-v2

This series is targeting net-next for 7.2. To make this series
self-contained in the networking code, I dropped the patches that remove
support for transformation cloning from the crypto API, which is a
further negative 275-line cleanup and optimization this series enables.
That will be done as a follow-up, either through the crypto tree for
7.3, or still through net-next for 7.2 at maintainer preference.

This series refactors the TCP-AO (TCP Authentication Option) code to do
MAC and KDF computations using lib/crypto/ instead of crypto_ahash.
This greatly simplifies the code and makes it much more efficient. The
entire tcp_sigpool mechanism becomes unnecessary and is removed, as the
problems it was designed to solve don't exist with the library APIs.

The crypto API's support for crypto transformation cloning also becomes
unnecessary and will be removed in follow-up patches. Note that as part
of that, we'll be able to roll back the addition of the reference count
to crypto_tfm, which had regressed performance for all crypto API users.

To make this simplification and optimization possible, this series also
updates the TCP-AO code to support a specific set of algorithms, rather
than arbitrary algorithms that don't make sense and are very likely not
being used, e.g. CRC-32 and HMAC-MD5.

Specifically, this series retains the support for AES-128-CMAC,
HMAC-SHA1, and HMAC-SHA256. AES-128-CMAC and HMAC-SHA1 are the only
algorithms that are actually standardized for use in TCP-AO, while
HMAC-SHA256 makes sense to continue supporting as a Linux extension. Of
course, other algorithms can still be (re-)added later if ever needed.
It's worth noting that TCP-AO MACs are limited to 20 bytes by the TCP
options space, which limits the benefit of further algorithm upgrades.

This series passes the tcp_ao selftests
(sudo make -C tools/testing/selftests/net/tcp_ao/ run_tests).

To get a sense for how much more efficient this makes the TCP-AO code,
here's a microbenchmark for tcp_ao_hash_skb() with skb->len == 128:

Algorithm Avg cycles (before) Avg cycles (after)
--------- ------------------- ------------------
HMAC-SHA1 3319 1256
HMAC-SHA256 3311 1344
AES-128-CMAC 2720 1107

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

Merge branch 'udp-retire-udp-lite'

Kuniyuki Iwashima says:

====================
udp: Retire UDP-Lite.

In 2023, syzbot found a null-ptr-deref bug triggered when UDP-Lite
attempted to charge an skb after the total memory usage for UDP-Lite
_and_ UDP exceeded a system-wide threshold, net.ipv4.udp_mem[1].

Since this threshold is shared with UDP, the bug would have been
easy to trigger if any real-world applications were using UDP-Lite;
however, only syzbot ever stumbled upon it.

The bug had persisted since 2016, suggesting that UDP-Lite had
remained unused for 7 years at that point.

The bug was fixed in commit ad42a35bdfc6 ("udplite: Fix NULL pointer
dereference in __sk_mem_raise_allocated()."), and we added another
commit be28c14ac8bb ("udplite: Print deprecation notice.") to
announce the deprecation plan.

Since then, no one has complained, so it is time to officially
retire UDP-Lite.

This series first removes IPv6 and IPv4 UDP-Lite sockets, then
gradually cleans up the remaining dead/unnecessary code within
the UDP stack.

By removing a bunch of conditionals for UDP-Lite from the fast
path, udp_rr with 20,000 flows sees a 10% increase in pps
(13.3 Mpps -> 14.7 Mpps) on an AMD EPYC 7B12 (Zen 2) 64-Core
Processor platform.

[ With FDO, the baseline is much higher and the delta was ~3%,
20.1 Mpps -> 20.7 Mpps ]

ipv4: Retire UDP-Lite.

We have deprecated IPv6 UDP-Lite sockets.

Let's drop support for IPv4 UDP-Lite sockets as well.

Most of the changes are similar to the IPv6 patch: removing
udplite.c and udp_impl.h, marking most functions in udp_impl.h
as static, moving the prototype for udp_recvmsg() to udp.h, and
adding INDIRECT_CALLABLE_SCOPE for it.

In addition, the INET_DIAG support for UDP-Lite is dropped.

We will remove the remaining dead code in the following patches.
