Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.

Core & protocols:

- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT

- Use flex array for netdevice priv area, ensure its cache alignment

- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful

- Support scheduling transmission of packets based on CLOCK_TAI

- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets

- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address

- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync

- Improve TCP compliance with RFC 9293 for simultaneous connect()

- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it

- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled

- Introduce IPPROTO_SMC for selecting SMC when socket is created

- Allow UDP GSO transmit from devices with no checksum offload

- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding

- nf_tables: shrink memory consumption for transaction objects

Things we sprinkled into general kernel code:

- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]

- Add IRQ information in sysfs for auxiliary bus

- Introduce guard definition for local_lock

- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures

BPF:

- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered

- Add new kfuncs for a generic, open-coded bits iterator

- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head

- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules

- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs

- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter

- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs

Driver API:

- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose

- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits

- Track additional RSS contexts in the core, make sure configuration
changes don't break them

- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
ESP data paths

- Support updating firmware on SFP modules

Tests and tooling:

- mptcp: use net/lib.sh to manage netns

tracepoints

idpf: XDP chapter I: convert Rx to libeth

Alexander Lobakin says:

XDP for idpf is currently 5 chapters:
* convert Rx to libeth (this);
* convert Tx and stats to libeth;
* generic XDP and XSk code changes, libeth_xdp;
* actual XDP for idpf via libeth_xdp;
* XSk for idpf (^).

Part I does the following:
* splits &idpf_queue into 4 (RQ, SQ, FQ, CQ) and puts them on a diet;
* ensures optimal cacheline placement, strictly asserts CL sizes;
* moves currently unused/dead singleq mode out of line;
* reuses libeth's Rx ptype definitions and helpers;
* uses libeth's Rx buffer management for both header and payload;
* eliminates memcpy()s and coherent DMA uses on hotpath, uses
napi_build_skb() instead of in-place short skb allocation.

Most idpf patches, except for the queue split, removes more lines
than adds.

Expect far better memory utilization and +5-8% on Rx depending on
the case (+17% on skb XDP_DROP :>).

* '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
idpf: use libeth Rx buffer management for payload buffer
idpf: convert header split mode to libeth + napi_build_skb()
libeth: support different types of buffers for Rx
idpf: remove legacy Page Pool Ethtool stats
idpf: reuse libeth's definitions of parsed ptype structures
idpf: compile singleq code only under default-n CONFIG_IDPF_SINGLEQ
idpf: merge singleq and splitq &net_device_ops
idpf: strictly assert cachelines of queue and queue vector structures
idpf: avoid bloating &idpf_q_vector with big %NR_CPUS
idpf: split &idpf_queue into 4 strictly-typed queue structures
idpf: stop using macros for accessing queue descriptors
libeth: add cacheline / struct layout assertion helpers
page_pool: use __cacheline_group_{begin, end}_aligned()
cache: add __cacheline_group_{begin, end}_aligned() (+ couple more)

idpf: compile singleq code only under default-n CONFIG_IDPF_SINGLEQ

Currently, all HW supporting idpf supports the singleq model, but none
of it advertises it by default, as splitq is supported and preferred
for multiple reasons. Still, this almost dead code often times adds
hotpath branches and redundant cacheline accesses.
While it can't currently be removed, add CONFIG_IDPF_SINGLEQ and build
the singleq code only when it's enabled manually. This corresponds to
-10 Kb of object code size and a good bunch of hotpath checks.
idpf_is_queue_model_split() works as a gate and compiles out to `true`
when the config option is disabled.

Merge tag 'net-next-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

- Complete rework of garbage collection of AF_UNIX sockets.

AF_UNIX is prone to forming reference count cycles due to fd
passing functionality. New method based on Tarjan's Strongly
Connected Components algorithm should be both faster and remove a
lot of workarounds we accumulated over the years.

- Add TCP fraglist GRO support, allowing chaining multiple TCP
packets and forwarding them together. Useful for small switches /
routers which lack basic checksum offload in some scenarios (e.g.
PPPoE).

- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't use
NAPI. This helps move the processing out of the softirq jumble.

- Continue work of converting from rtnl lock to RCU protection.

Don't require rtnl lock when reading: IPv6 routing FIB, IPv6
address labels, netdev threaded NAPI sysfs files, bonding driver's
sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics,
TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot
of the link information available via rtnetlink.

- Small optimizations from Eric to UDP wake up handling, memory
accounting, RPS/RFS implementation, TCP packet sizing etc.

- Allow direct page recycling in the bulk API used by XDP, for +2%
PPS.

- Support peek with an offset on TCP sockets.

- Add MPTCP APIs for querying last time packets were received/sent/acked
and whether MPTCP "upgrade" succeeded on a TCP socket.

- Add intra-node communication shortcut to improve SMC performance.

- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol
driver.

- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.

- Add reset reasons for tracing what caused a TCP reset to be sent.

- Introduce direction attribute for xfrm (IPSec) states. State can be
used either for input or output packet processing.

Things we sprinkled into general kernel code:

- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().

This required touch-ups and renaming of a few existing users.

- Add Endian-dependent __counted_by_{le,be} annotations.

- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.

Netfilter:

- Use GFP_KERNEL to clone elements, to deal better with OOM
situations and avoid failures in the .commit step.

BPF:

- Add eBPF JIT for ARCv2 CPUs.

- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function
entry and return, the entry program can decide if the return
program gets executed and the entry program can share u64 cookie
value with return program. "Session mode" is a common use-case for
tetragon and bpftrace.

- Add the ability to specify and retrieve BPF cookie for raw
tracepoint programs in order to ease migration from classic to raw
tracepoints.

- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V
JITs. This allows inlining functions which need to access per-CPU
state.

- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86
instruction. Support BPF arena on ARM64.

- Add a new bpf_wq API for deferring events and refactor
process-context bpf_timer code to keep common code where possible.

- Harden the BPF verifier's and/or/xor value tracking.

- Introduce crypto kfuncs to let BPF programs call kernel crypto
APIs.

- Support bpf_tail_call_static() helper for BPF programs with GCC 13.

- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.

Driver API:

- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by
rule.

- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line)
config.

- Initial bits of a queue control API, for now allowing a single
queue to be reset without disturbing packet flow to other queues.

- Common (ethtool) statistics for hardware timestamping.

Tests and tooling:

- Remove the need to create a config file to run the net forwarding
tests so that a naive "make run_tests" can exercise them.

- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test
machine). Add a few such tests.

- Create a shared code library for writing Python tests. Expose the
YAML Netlink library from tools/ to the tests for easy Netlink
access.

- Move netfilter tests under net/, extend them, separate performance
tests from correctness tests, and iron out issues found by running
them "on every commit".

- Refactor BPF selftests to use common network helpers.

- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF
info, TC u32 mark, TC police action.

- Teach Python YAML Netlink to decode attribute policies.

- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.

- Add hyperlinks between definitions in generated Netlink docs.

Drivers:

- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application
rather than dmesg (large number of driver changes from Asbjørn
Sloth Tønnesen).

- Ethernet high-speed NICs:
- Broadcom (bnxt):
- support multiple RSS contexts and steering traffic to them
- support XDP metadata
- make page pool allocations more NUMA aware

====================
net: intel: start The Great Code Dedup + Page Pool for iavf

Alexander Lobakin says:

Here's a two-shot: introduce {,Intel} Ethernet common library (libeth and
libie) and switch iavf to Page Pool. Details are in the commit messages;
here's a summary:

Not a secret there's a ton of code duplication between two and more Intel
ethernet modules. Before introducing new changes, which would need to be
copied over again, start decoupling the already existing duplicate
functionality into a new module, which will be shared between several
Intel Ethernet drivers. The first name that came to my mind was
"libie" -- "Intel Ethernet common library". Also this sounds like
"lovelie" (-> one word, no "lib I E" pls) and can be expanded as
"lib Internet Explorer" :P
The "generic", pure-software part is placed separately, so that it can be
easily reused in any driver by any vendor without linking to the Intel
pre-200G guts. In a few words, it's something any modern driver does the
same way, but nobody moved it level up (yet).
The series is only the beginning. From now on, adding every new feature
or doing any good driver refactoring will remove much more lines than add
for quite some time. There's a basic roadmap with some deduplications
planned already, not speaking of that touching every line now asks:
"can I share this?". The final destination is very ambitious: have only
one unified driver for at least i40e, ice, iavf, and idpf with a struct
ops for each generation. That's never gonna happen, right? But you still
can at least try.
PP conversion for iavf lands within the same series as these two are tied
closely. libie will support Page Pool model only, so that a driver can't
use much of the lib until it's converted. iavf is only the example, the
rest will eventually be converted soon on a per-driver basis. That is
when it gets really interesting. Stay tech.

* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
MAINTAINERS: add entry for libeth and libie
iavf: switch to Page Pool
iavf: pack iavf_ring more efficiently
libeth: add Rx buffer management
page_pool: add DMA-sync-for-CPU inline helper
page_pool: constify some read-only function arguments
slab: introduce kvmalloc_array_node() and kvcalloc_node()
iavf: drop page splitting and recycling
iavf: kill "legacy-rx" for good

net: intel: introduce {, Intel} Ethernet common library

Not a secret there's a ton of code duplication between two and more Intel
ethernet modules.

Before introducing new changes, which would need to be copied over again,
start decoupling the already existing duplicate functionality into a new
module, which will be shared between several Intel Ethernet drivers.
Add the lookup table which converts 8/10-bit hardware packet type into
a parsed bitfield structure for easy checking packet format parameters,
such as payload level, IP version, etc. This is currently used by i40e,
ice and iavf and it's all the same in all three drivers.
The only difference introduced in this implementation is that instead of
defining a 256 (or 1024 in case of ice) element array, add unlikely()
condition to limit the input to 154 (current maximum non-reserved packet
type). There's no reason to waste 600 (or even 3600) bytes only to not
hurt very unlikely exception packets.
The hash computation function now takes payload level directly as a
pkt_hash_type. There's a couple cases when non-IP ptypes are marked as
L3 payload and in the previous versions their hash level would be 2, not
3. But skb_set_hash() only sees difference between L4 and non-L4, thus
this won't change anything at all.
The module is behind the hidden Kconfig symbol, which the drivers will
select when needed. The exports are behind 'LIBIE' namespace to limit
the scope of the functions.

Not that non-HW-specific symbols will live in yet another module,
libeth. This is done to easily distinguish pretty generic code ready
for reusing by any other vendor and/or for moving the layer up from
the code useful in Intel's 1-100G drivers only.

net: handle HAS_IOPORT dependencies

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for
those drivers requiring them. For the DEFXX driver the use of I/O
ports is optional and we only need to fence specific code paths. It also
turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need
the !S390 dependency and successfully builds the bpqether driver.
