Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski: "Core:
- Add dedicated kmem_cache for typical/small skb->head, avoid having to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used to describe messages used by each family and auto-generate parsers. Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols:
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt races of the out-of-band /proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.

- Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return error messages directly to user space, update the SJW handling, including the definition of a new default value that will benefit CAN-FD controllers, by increasing their oscillator tolerance.

Merge branch 'rmnet-tx-pkt-aggregation'
Daniele Palmas says:
==================== net: add tx packets aggregation to ethtool and rmnet
Hello maintainers and all,
this patchset implements tx qmap packets aggregation in rmnet and generic ethtool support for that.
Some low-cat Thread-x based modems are not capable of properly reaching the maximum allowed throughput both in tx and rx during a bidirectional test if tx packets aggregation is not enabled.
I verified this problem with rmnet + qmi_wwan by using a MDM9207 Cat. 4 based modem (50Mbps/150Mbps max throughput). What is actually happening is pictured at https://drive.google.com/file/d/1gSbozrtd9h0X63i6vdkNpN68d-9sg8f9/view
Testing with iperf TCP, when rx and tx flows are tested singularly there's no issue in tx and minor issues in rx (not able to reach max throughput). When there are concurrent tx and rx flows, tx throughput has an huge drop. rx a minor one, but still present.
The same scenario with tx aggregation enabled is pictured at https://drive.google.com/file/d/1jcVIKNZD7K3lHtwKE5W02mpaloudYYih/view showing a regular graph.
This issue does not happen with high-cat modems (e.g. SDX20), or at least it does not happen at the throughputs I'm able to test currently: maybe the same could happen when moving close to the maximum rates supported by those modems. Anyway, having the tx aggregation enabled should not hurt.
The first attempt to solve this issue was in qmi_wwan qmap implementation, see the discussion at https://lore.kernel.org/netdev/20221019132503.6783-1-dnlplm@gmail.com/
However, it turned out that rmnet was a better candidate for the implementation.
Moreover, Greg and Jakub suggested also to use ethtool for the configuration: not sure if I got their advice right, but this patchset add also generic ethtool support for tx aggregation.
The patches have been tested mainly against an MDM9207 based modem through USB and SDX55 through PCI (MHI).
v2 should address the comments highlighted in the review: the implementation is still in rmnet, due to Subash's request of keeping tx aggregation there.
v3 fixes ethtool-netlink.rst content out of table bounds and a W=1 build warning for patch 2.
v4 solves a race related to egress_agg_params. ====================

net: qualcomm: rmnet: add tx packets aggregation
Add tx packets aggregation.
Bidirectional TCP throughput tests through iperf with low-cat Thread-x based modems revelead performance issues both in tx and rx.
The Windows driver does not show this issue: inspecting USB packets revealed that the only notable change is the driver enabling tx packets aggregation.
Tx packets aggregation is by default disabled and can be enabled by increasing the value of ETHTOOL_A_COALESCE_TX_MAX_AGGR_FRAMES.
The maximum aggregated size is by default set to a reasonably low value in order to support the majority of modems.
This implementation is based on patches available in Code Aurora repositories (msm kernel) whose main authors are

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.

net: add per-cpu storage and net->core_stats
Before adding yet another possibly contended atomic_long_t, it is time to add per-cpu storage for existing ones: dev->tx_dropped, dev->rx_dropped, and dev->rx_nohandler
Because many devices do not have to increment such counters, allocate the per-cpu storage on demand, so that dev_get_stats() does not have to spend considerable time folding zero counters.
Note that some drivers have abused these counters which were supposed to be only used by core networking stack.
v4: should use per_cpu_ptr() in dev_get_stats() (Jakub) v3: added a READ_ONCE() in netdev_core_stats_alloc() (Paolo) v2: add a missing include (reported by kernel test robot <lkp@intel.com>) Change in netdev_core_stats_alloc() (Jakub)
