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.

+DT bindings for Xilinx video IP cores
+-------------------------------------
+
+Xilinx video IP cores process video streams by acting as video sinks and/or
+sources. They are connected by links through their input and output ports,
+creating a video pipeline.
+
+Each video IP core is represented by an AMBA bus child node in the device
+tree using bindings documented in this directory. Connections between the IP
+cores are represented as defined in ../video-interfaces.txt.
+
+The whole  pipeline is represented by an AMBA bus child node in the device
+tree using bindings documented in ./xlnx,video.txt.
+
+Common properties
+-----------------
+
+The following properties are common to all Xilinx video IP cores.
+
+- xlnx,video-format: This property represents a video format transmitted on an
+  AXI bus between video IP cores, using its VF code as defined in "AXI4-Stream
+  Video IP and System Design Guide" [UG934]. How the format relates to the IP
+  core is described in the IP core bindings documentation.
+
+- xlnx,video-width: This property qualifies the video format with the sample
+  width expressed as a number of bits per pixel component. All components must
+  use the same width.
+
+- xlnx,cfa-pattern: When the video format is set to Mono/Sensor, this property
+  describes the sensor's color filter array pattern. Supported values are
+  "bggr", "gbrg", "grbg", "rggb" and "mono". If not specified, the pattern
+  defaults to "mono".

+title: Xilinx MIPI CSI-2 Receiver Subsystem
+
+maintainers:
+  - Vishal Sagar <vishal.sagar@xilinx.com>
+
+description: |
+  The Xilinx MIPI CSI-2 Receiver Subsystem is used to capture MIPI CSI-2
+  traffic from compliant camera sensors and send the output as AXI4 Stream
+  video data for image processing.
+  The subsystem consists of a MIPI D-PHY in slave mode which captures the
+  data packets. This is passed along the MIPI CSI-2 Rx IP which extracts the
+  packet data. The optional Video Format Bridge (VFB) converts this data to
+  AXI4 Stream video data.
+  For more details, please refer to PG232 Xilinx MIPI CSI-2 Receiver Subsystem.
+  Please note that this bindings includes only the MIPI CSI-2 Rx controller
+  and Video Format Bridge and not D-PHY.

+Xilinx Video Test Pattern Generator (TPG)
+-----------------------------------------
+
+Required properties:
+
+- compatible: Must contain at least one of
+
+    "xlnx,v-tpg-5.0" (TPG version 5.0)
+    "xlnx,v-tpg-6.0" (TPG version 6.0)
+
+  TPG versions backward-compatible with previous versions should list all
+  compatible versions in the newer to older order.
+
+- reg: Physical base address and length of the registers set for the device.
+
+- clocks: Reference to the video core clock.
+
+- xlnx,video-format, xlnx,video-width: Video format and width, as defined in
+  video.txt.
+
+- port: Video port, using the DT bindings defined in ../video-interfaces.txt.
+  The TPG has a single output port numbered 0.
+
+Optional properties:
+
+- xlnx,vtc: A phandle referencing the Video Timing Controller that generates
+  video timings for the TPG test patterns.
+
+- timing-gpios: Specifier for a GPIO that controls the timing mux at the TPG
+  input. The GPIO active level corresponds to the selection of VTC-generated
+  video timings.
+
+The xlnx,vtc and timing-gpios properties are mandatory when the TPG is
+synthesized with two ports and forbidden when synthesized with one port.
+
+Example:
+
+	tpg_0: tpg@40050000 {
+		compatible = "xlnx,v-tpg-6.0", "xlnx,v-tpg-5.0";
+		reg = <0x40050000 0x10000>;
+		clocks = <&clkc 15>;
+
+		xlnx,vtc = <&vtc_3>;
+		timing-gpios = <&ps7_gpio_0 55 GPIO_ACTIVE_LOW>;
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				reg = <0>;
+
+				xlnx,video-format = <XVIP_VF_YUV_422>;
+				xlnx,video-width = <8>;
+
+				tpg_in: endpoint {
+					remote-endpoint = <&adv7611_out>;
+				};
+			};
+			port@1 {
+				reg = <1>;
+
+				xlnx,video-format = <XVIP_VF_YUV_422>;
+				xlnx,video-width = <8>;
+
+				tpg1_out: endpoint {
+					remote-endpoint = <&switch_in0>;
+				};
+			};
+		};
+	};

+Xilinx Video IP Pipeline (VIPP)
+-------------------------------
+
+General concept
+---------------
+
+Xilinx video IP pipeline processes video streams through one or more Xilinx
+video IP cores. Each video IP core is represented as documented in video.txt
+and IP core specific documentation, xlnx,v-*.txt, in this directory. The DT
+node of the VIPP represents as a top level node of the pipeline and defines
+mappings between DMAs and the video IP cores.
+
+Required properties:
+
+- compatible: Must be "xlnx,video".
+
+- dmas, dma-names: List of one DMA specifier and identifier string (as defined
+  in Documentation/devicetree/bindings/dma/dma.txt) per port. Each port
+  requires a DMA channel with the identifier string set to "port" followed by
+  the port index.
+
+- ports: Video port, using the DT bindings defined in ../video-interfaces.txt.
+
+Required port properties:
+
+- direction: should be either "input" or "output" depending on the direction
+  of stream.
+
+Example:
+
+	video_cap {
+		compatible = "xlnx,video";
+		dmas = <&vdma_1 1>, <&vdma_3 1>;
+		dma-names = "port0", "port1";
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				reg = <0>;
+				direction = "input";
+				vcap0_in0: endpoint {
+					remote-endpoint = <&scaler0_out>;
+				};
+			};
+			port@1 {
+				reg = <1>;
+				direction = "input";
+				vcap0_in1: endpoint {
+					remote-endpoint = <&switch_out1>;
+				};
+			};
+		};
+	};
