Merge tag 'net-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"The sprinkling of SPI drivers is because we added a new one and Mark
sent us a SPI driver interface conversion pull request.

Core
----

- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).

- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.

- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).

- Continue the work of annotating packet drop reasons throughout the
stack.

- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.

- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.

- Extend the ref_tracker to allow catching use-after-free bugs.

BPF
---

- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower iTLB
pressure and prevents identity mapping huge pages from getting
split.

- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.

- Convert the BPF preload to use light skeleton and drop the
user-mode-driver dependency.

- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.

- Allow local storage memory to be allocated with GFP_KERNEL if
called from a hook allowed to sleep.

- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).

- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.

- Allow cgroup BPF progs to return custom errors to user space.

- Add support for AF_UNIX iterator batching.

- Allow iterator programs to use sleepable helpers.

- Support JIT of add, and, or, xor and xchg atomic ops on arm64.

- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.

- Large number of libbpf API improvements, cleanups and deprecations.

Protocols
---------

- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.

- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.

- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.

- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.

- Support inserting IPv6 IOAM information to a fraction of frames.

- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)

- Support setting socket and IPv6 options via cmsg on ping6 sockets.

- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.

- Add support for locked bridge ports (for 802.1X).

- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.

- IPv6 extension header handling in Open vSwitch.

- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.

- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY

- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)

- Multi-BSSID beacon handling in AP mode for WiFi.

- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events

- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements

- Increase the max PDU size in CAN ISOTP to 64 kB.

Driver API
----------

- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.

- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.

- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.

- Add header/data split indication to guide user space enabling of
TCP zero-copy Rx.

- Allow configuring completion queue event size.

- Refactor page_pool to enable fragmenting after allocation.

- Add allocation and page reuse statistics to page_pool.

- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.

- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

Merge branch 'bpf-light-skel'

Alexei Starovoitov says:

====================
The libbpf performs a set of complex operations to load BPF programs.
With "loader program" and "CO-RE in the kernel" the loading job of
libbpf was diminished. The light skeleton became lean enough to perform
program loading and map creation tasks without libbpf.
It's now possible to tweak it further to make light skeleton usable
out of user space and out of kernel module.
This allows bpf_preload.ko to drop user-mode-driver usage,
drop host compiler dependency, allow cross compilation and simplify the
code. It's a building block toward safe and portable kernel modules.

v3->v4:
- inlined skel_prep_init_value() as direct assignment in lskel

v2->v3:
- dropped vm_mmap() and switched to bpf_loader_ctx->flags & KERNEL approach.
It allows bpf_preload.ko to be built-in.
The kernel is able to load bpf progs before init process starts.
- added comments (Yonghong's review)
- added error checks in lskel (Andrii's review)
- added Acks in all but 2nd patch.

v1->v2:
- removed redundant anon struct and added comments (Andrii's reivew)
- added Yonghong's ack
- fixed build warning when JIT is off

bpf: Convert bpf_preload.ko to use light skeleton.

The main change is a move of the single line
#include "iterators.lskel.h"
from iterators/iterators.c to bpf_preload_kern.c.
Which means that generated light skeleton can be used from user space or
user mode driver like iterators.c or from the kernel module or the kernel itself.
The direct use of light skeleton from the kernel module simplifies the code,
since UMD is no longer necessary. The libbpf.a required user space and UMD. The
CO-RE in the kernel and generated "loader bpf program" used by the light
skeleton are capable to perform complex loading operations traditionally
provided by libbpf. In addition UMD approach was launching UMD process
every time bpffs has to be mounted. With light skeleton in the kernel
the bpf_preload kernel module loads bpf iterators once and pins them
multiple times into different bpffs mounts.
