Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextgrafted

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.

   - Add support for per action HW stats in TC.

   - Support hardware miss to TC action (continue processing in SW from
     a specific point in the action chain).

   - 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.

+* ASPEED AST2400 and AST2500 coprocessor interrupt controller
+
+This file describes the bindings for the interrupt controller present
+in the AST2400 and AST2500 BMC SoCs which provides interrupt to the
+ColdFire coprocessor.
+
+It is not a normal interrupt controller and it would be rather
+inconvenient to create an interrupt tree for it as it somewhat shares
+some of the same sources as the main ARM interrupt controller but with
+different numbers.
+
+The AST2500 supports a SW generated interrupt
+
+Required properties:
+- reg: address and length of the register for the device.
+- compatible: "aspeed,cvic" and one of:
+		"aspeed,ast2400-cvic"
+	      or
+		"aspeed,ast2500-cvic"
+
+- valid-sources: One cell, bitmap of supported sources for the implementation
+
+Optional properties;
+- copro-sw-interrupts: List of interrupt numbers that can be used as
+		       SW interrupts from the ARM to the coprocessor.
+		       (AST2500 only)
+
+Example:
+
+	cvic: copro-interrupt-controller@1e6c2000 {
+		compatible = "aspeed,ast2500-cvic";
+		valid-sources = <0xffffffff>;
+		copro-sw-interrupts = <1>;
+		reg = <0x1e6c2000 0x80>;
+	};

+======================================================================
+Device tree bindings for Aspeed AST2400/AST2500 PCI-to-AHB Bridge Control Driver
+======================================================================
+
+The bridge is available on platforms with the VGA enabled on the Aspeed device.
+In this case, the host has access to a 64KiB window into all of the BMC's
+memory.  The BMC can disable this bridge.  If the bridge is enabled, the host
+has read access to all the regions of memory, however the host only has read
+and write access depending on a register controlled by the BMC.
+
+Required properties:
+===================
+
+ - compatible: must be one of:
+	- "aspeed,ast2400-p2a-ctrl"
+	- "aspeed,ast2500-p2a-ctrl"
+
+Optional properties:
+===================
+
+- reg: A hint for the memory regions associated with the P2A controller
+- memory-region: A phandle to a reserved_memory region to be used for the PCI
+		to AHB mapping
+
+The p2a-control node should be the child of a syscon node with the required
+property:
+
+- compatible : Should be one of the following:
+		"aspeed,ast2400-scu", "syscon", "simple-mfd"
+		"aspeed,ast2500-scu", "syscon", "simple-mfd"

+* Atmel SSC driver.
+
+Required properties:
+- compatible: "atmel,at91rm9200-ssc" or "atmel,at91sam9g45-ssc"
+	- atmel,at91rm9200-ssc: support pdc transfer
+	- atmel,at91sam9g45-ssc: support dma transfer
+- reg: Should contain SSC registers location and length
+- interrupts: Should contain SSC interrupt
+- clock-names: tuple listing input clock names.
+	Required elements: "pclk"
+- clocks: phandles to input clocks.
+
+
+Required properties for devices compatible with "atmel,at91sam9g45-ssc":
+- dmas: DMA specifier, consisting of a phandle to DMA controller node,
+  the memory interface and SSC DMA channel ID (for tx and rx).
+  See Documentation/devicetree/bindings/dma/atmel-dma.txt for details.
+- dma-names: Must be "tx", "rx".
+
+Optional properties:
+  - atmel,clk-from-rk-pin: bool property.
+     - When SSC works in slave mode, according to the hardware design, the
+       clock can get from TK pin, and also can get from RK pin. So, add
+       this parameter to choose where the clock from.
+     - By default the clock is from TK pin, if the clock from RK pin, this
+       property is needed.
+  - #sound-dai-cells: Should contain <0>.
+     - This property makes the SSC into an automatically registered DAI.

+* Freescale Management Complex
+
+The Freescale Management Complex (fsl-mc) is a hardware resource
+manager that manages specialized hardware objects used in
+network-oriented packet processing applications. After the fsl-mc
+block is enabled, pools of hardware resources are available, such as
+queues, buffer pools, I/O interfaces. These resources are building
+blocks that can be used to create functional hardware objects/devices
+such as network interfaces, crypto accelerator instances, L2 switches,
+etc.
+
+For an overview of the DPAA2 architecture and fsl-mc bus see:
+Documentation/networking/device_drivers/ethernet/freescale/dpaa2/overview.rst
+
+As described in the above overview, all DPAA2 objects in a DPRC share the
+same hardware "isolation context" and a 10-bit value called an ICID
+(isolation context id) is expressed by the hardware to identify
+the requester.
+
+The generic 'iommus' property is insufficient to describe the relationship
+between ICIDs and IOMMUs, so an iommu-map property is used to define
+the set of possible ICIDs under a root DPRC and how they map to
+an IOMMU.
+
+For generic IOMMU bindings, see
+Documentation/devicetree/bindings/iommu/iommu.txt.
+
+For arm-smmu binding, see:
+Documentation/devicetree/bindings/iommu/arm,smmu.yaml.
+
+The MSI writes are accompanied by sideband data which is derived from the ICID.
+The msi-map property is used to associate the devices with both the ITS
+controller and the sideband data which accompanies the writes.
+
+For generic MSI bindings, see
+Documentation/devicetree/bindings/interrupt-controller/msi.txt.
+
+For GICv3 and GIC ITS bindings, see:

+* Xilinx SDFEC(16nm) IP *
+
+The Soft Decision Forward Error Correction (SDFEC) Engine is a Hard IP block
+which provides high-throughput LDPC and Turbo Code implementations.
+The LDPC decode & encode functionality is capable of covering a range of
+customer specified Quasi-cyclic (QC) codes. The Turbo decode functionality
+principally covers codes used by LTE. The FEC Engine offers significant
+power and area savings versus implementations done in the FPGA fabric.
+
+
+Required properties:
+- compatible: Must be "xlnx,sd-fec-1.1"
+- clock-names : List of input clock names from the following:
+    - "core_clk", Main processing clock for processing core (required)
+    - "s_axi_aclk", AXI4-Lite memory-mapped slave interface clock (required)
+    - "s_axis_din_aclk", DIN AXI4-Stream Slave interface clock (optional)
+    - "s_axis_din_words-aclk", DIN_WORDS AXI4-Stream Slave interface clock (optional)
+    - "s_axis_ctrl_aclk",  Control input AXI4-Stream Slave interface clock (optional)
+    - "m_axis_dout_aclk", DOUT AXI4-Stream Master interface clock (optional)
+    - "m_axis_dout_words_aclk", DOUT_WORDS AXI4-Stream Master interface clock (optional)
+    - "m_axis_status_aclk", Status output AXI4-Stream Master interface clock (optional)
+- clocks : Clock phandles (see clock_bindings.txt for details).
+- reg: Should contain Xilinx SDFEC 16nm Hardened IP block registers
+  location and length.
+- xlnx,sdfec-code : Should contain "ldpc" or "turbo" to describe the codes
+  being used.
+- xlnx,sdfec-din-words : A value 0 indicates that the DIN_WORDS interface is
+  driven with a fixed value and is not present on the device, a value of 1
+  configures the DIN_WORDS to be block based, while a value of 2 configures the
+  DIN_WORDS input to be supplied for each AXI transaction.
+- xlnx,sdfec-din-width : Configures the DIN AXI stream where a value of 1
+  configures a width of "1x128b", 2 a width of "2x128b" and 4 configures a width
+  of "4x128b".
+- xlnx,sdfec-dout-words : A value 0 indicates that the DOUT_WORDS interface is
+  driven with a fixed value and is not present on the device, a value of 1
+  configures the DOUT_WORDS to be block based, while a value of 2 configures the
+  DOUT_WORDS input to be supplied for each AXI transaction.
+- xlnx,sdfec-dout-width : Configures the DOUT AXI stream where a value of 1
+  configures a width of "1x128b", 2 a width of "2x128b" and 4 configures a width
+  of "4x128b".
+Optional properties:
+- interrupts: should contain SDFEC interrupt number
