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.

+ZHAW InES PTP time stamping IP core
+
+The IP core needs two different kinds of nodes.  The control node
+lives somewhere in the memory map and specifies the address of the
+control registers.  There can be up to three port handles placed as
+attributes of PHY nodes.  These associate a particular MII bus with a
+port index within the IP core.
+
+Required properties of the control node:
+
+- compatible:		"ines,ptp-ctrl"
+- reg:			physical address and size of the register bank
+
+Required format of the port handle within the PHY node:
+
+- timestamper:		provides control node reference and
+			the port channel within the IP core
+
+Example:
+
+	tstamper: timestamper@60000000 {
+		compatible = "ines,ptp-ctrl";
+		reg = <0x60000000 0x80>;

+* Freescale QorIQ 1588 timer based PTP clock
+
+General Properties:
+
+  - compatible   Should be "fsl,etsec-ptp" for eTSEC
+                 Should be "fsl,fman-ptp-timer" for DPAA FMan
+                 Should be "fsl,dpaa2-ptp" for DPAA2
+                 Should be "fsl,enetc-ptp" for ENETC
+  - reg          Offset and length of the register set for the device
+  - interrupts   There should be at least two interrupts. Some devices
+                 have as many as four PTP related interrupts.
+
+Clock Properties:
+
+  - fsl,cksel        Timer reference clock source.
+  - fsl,tclk-period  Timer reference clock period in nanoseconds.
+  - fsl,tmr-prsc     Prescaler, divides the output clock.
+  - fsl,tmr-add      Frequency compensation value.
+  - fsl,tmr-fiper1   Fixed interval period pulse generator.
+  - fsl,tmr-fiper2   Fixed interval period pulse generator.
+  - fsl,tmr-fiper3   Fixed interval period pulse generator.
+                     Supported only on DPAA2 and ENETC hardware.
+  - fsl,max-adj      Maximum frequency adjustment in parts per billion.
+  - fsl,extts-fifo   The presence of this property indicates hardware
+		     support for the external trigger stamp FIFO.
+  - little-endian    The presence of this property indicates the 1588 timer
+		     IP block is little-endian mode. The default endian mode
+		     is big-endian.
+
+  These properties set the operational parameters for the PTP
+  clock. You must choose these carefully for the clock to work right.
+  Here is how to figure good values:
+
+  TimerOsc     = selected reference clock   MHz
+  tclk_period  = desired clock period       nanoseconds
+  NominalFreq  = 1000 / tclk_period         MHz
+  FreqDivRatio = TimerOsc / NominalFreq     (must be greater that 1.0)
+  tmr_add      = ceil(2^32 / FreqDivRatio)
+  OutputClock  = NominalFreq / tmr_prsc     MHz
+  PulseWidth   = 1 / OutputClock            microseconds
+  FiperFreq1   = desired frequency in Hz
+  FiperDiv1    = 1000000 * OutputClock / FiperFreq1
+  tmr_fiper1   = tmr_prsc * tclk_period * FiperDiv1 - tclk_period
+  max_adj      = 1000000000 * (FreqDivRatio - 1.0) - 1
+
+  The calculation for tmr_fiper2 is the same as for tmr_fiper1. The
+  driver expects that tmr_fiper1 will be correctly set to produce a 1
+  Pulse Per Second (PPS) signal, since this will be offered to the PPS
+  subsystem to synchronize the Linux clock.
+
+  Reference clock source is determined by the value, which is holded
+  in CKSEL bits in TMR_CTRL register. "fsl,cksel" property keeps the
+  value, which will be directly written in those bits, that is why,
+  according to reference manual, the next clock sources can be used:
+
+  For eTSEC,
+  <0> - external high precision timer reference clock (TSEC_TMR_CLK
+        input is used for this purpose);
+  <1> - eTSEC system clock;
+  <2> - eTSEC1 transmit clock;
+  <3> - RTC clock input.
+
+  For DPAA FMan,
+  <0> - external high precision timer reference clock (TMR_1588_CLK)
+  <1> - MAC system clock (1/2 FMan clock)
+  <2> - reserved
+  <3> - RTC clock oscillator
+
+  When this attribute is not used, the IEEE 1588 timer reference clock
+  will use the eTSEC system clock (for Gianfar) or the MAC system
+  clock (for DPAA).
+
+Example:
+
+	ptp_clock@24e00 {
+		compatible = "fsl,etsec-ptp";
+		reg = <0x24E00 0xB0>;
+		interrupts = <12 0x8 13 0x8>;
+		interrupt-parent = < &ipic >;
+		fsl,cksel       = <1>;
+		fsl,tclk-period = <10>;
+		fsl,tmr-prsc    = <100>;
+		fsl,tmr-add     = <0x999999A4>;
+		fsl,tmr-fiper1  = <0x3B9AC9F6>;
+		fsl,tmr-fiper2  = <0x00018696>;

+Time stamps from MII bus snooping devices
+
+This binding supports non-PHY devices that snoop the MII bus and
+provide time stamps.  In contrast to PHY time stamping drivers (which
+can simply attach their interface directly to the PHY instance), stand
+alone MII time stamping drivers use this binding to specify the
+connection between the snooping device and a given network interface.
+
+Non-PHY MII time stamping drivers typically talk to the control
+interface over another bus like I2C, SPI, UART, or via a memory mapped
+peripheral.  This controller device is associated with one or more
+time stamping channels, each of which snoops on a MII bus.
+
+The "timestamper" property lives in a phy node and links a time
+stamping channel from the controller device to that phy's MII bus.
+
+Example:
+
+	tstamper: timestamper@10000000 {
+		compatible = "ines,ptp-ctrl";
+		reg = <0x10000000 0x80>;
+	};
+
+	ethernet@20000000 {
+		mdio {
+			ethernet-phy@1 {
+				timestamper = <&tstamper 0>;
+			};
+		};
+	};
+
+	ethernet@30000000 {
+		mdio {
+			ethernet-phy@2 {
+				timestamper = <&tstamper 1>;
+			};
+		};
+	};
+
+In this example, time stamps from the MII bus attached to phy@1 will
+appear on time stamp channel 0 (zero), and those from phy@2 appear on
+channel 1.
