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 'add-ethtool-support-for-completion-queue-event-size'

Subbaraya Sundeep says:

====================
Add ethtool support for completion queue event size

After a packet is sent or received by NIC then NIC posts
a completion queue event which consists of transmission status
(like send success or error) and received status(like
pointers to packet fragments). These completion events may
also use a ring similar to rx and tx rings. This patchset
introduces cqe-size ethtool parameter to modify the size
of the completion queue event if NIC hardware has that capability.
A bigger completion queue event can have more receive buffer pointers
inturn NIC can transfer a bigger frame from wire as long as
hardware(MAC) receive frame size limit is not exceeded.

Patch 1 adds support setting/getting cqe-size via
ethtool -G and ethtool -g.

Patch 2 includes octeontx2 driver changes to use
completion queue event size set from ethtool -G.

Merge tag '5.17-net-next' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core
----

- Defer freeing TCP skbs to the BH handler, whenever possible, or at
least perform the freeing outside of the socket lock section to
decrease cross-CPU allocator work and improve latency.

- Add netdevice refcount tracking to locate sources of netdevice and
net namespace refcount leaks.

- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.

- Various small optimizations throughout the stack from Eric Dumazet.

- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.

- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.

- Extend skb drop tracepoint with a drop reason.

- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.

BPF

don't have any quirks and where MAC capability bits fully express
what's supported. Allow PCS layer to participate in the validation.
Convert a number of drivers.

- Add support to set/get size of buffers on the Rx rings and size of
the tx copybreak buffer via ethtool.

ethtool and hns3 driver implements them.

Tx copybreak buf size is used for tx copybreak feature which for small size
packet or frag. Use ethtool --get-tunable command to get it, and ethtool
--set-tunable command to set it, examples are as follow:

1. set tx spare buf size to 102400:
$ ethtool --set-tunable eth1 tx-buf-size 102400

2. get tx spare buf size:
$ ethtool --get-tunable eth1 tx-buf-size
tx-buf-size: 102400

Rx buf len is buffer length of each rx BD. Use ethtool -g command to get
it, and ethtool -G command to set it, examples are as follow:

1. set rx buf len to 4096
$ ethtool -G eth1 rx-buf-len 4096

2. get rx buf len
$ ethtool -g eth1
...
RX Buf Len: 4096

Change log:
V5 -> V6
1.Fix compile error for divers/s390.

V4 -> V5
1.Change struct ethtool_ringparam_ext to kernel_ethtool_ringparam.
2.change "__u32 rx_buf_len" to "u32 rx_buf_len".

V3 -> V4
1.Fix a few allmodconfig compile warning.
2.Add more '=' synbol to ethtool-netlink.rst to refine format.
3.Move definement of struct ethtool_ringparam_ext to include/linux/ethtool.h.
4.Move related modify of rings_fill_reply() from patch 4/6 to patch 3/6.

V2 -> V3
1.Remove documentation for tx copybreak buf size, there is description for
it in userspace ethtool.
2.Move extending parameters for get/set_ringparam function from patch3/6
to patch 4/6.

V1 -> V2
1.Add documentation for rx buf len and tx copybreak buf size.
2.Extend structure ringparam_ext for extenal ring params.
3.Change type of ETHTOOL_A_RINGS_RX_BUF_LEN from NLA_U32 to
NLA_POLICY_MIN(NLA_U32, 1).
4.Add supported_ring_params in ethtool_ops to indicate if support external
params.
