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.

+Special thanks to:
+
+  Inaky Perez Gonzalez <inaky@peloncho.fis.ucm.es> for starting the
+  Linux USB driver effort and writing much of the larger uusbd driver.
+  Much has been learned from that effort.
+
+  The NetBSD & FreeBSD USB developers.  For being on the Linux USB list
+  and offering suggestions and sharing implementation experiences.
+
+Additional thanks to the following companies and people for donations
+of hardware, support, time and development (this is from the original
+THANKS file in Inaky's driver):

+        of Linux USB / UUSBD:
+
+	- 3Com GmbH for donating a ISDN Pro TA and supporting me
+	  in technical questions and with test equipment. I'd never 
+	  expect such a great help.
+
+        - USAR Systems provided us with one of their excellent USB
+          Evaluation Kits. It allows us to test the Linux-USB driver
+          for compliance with the latest USB specification. USAR
+          Systems recognized the importance of an up-to-date open
+          Operating System and supports this project with
+          Hardware. Thanks!.
+
+        - Thanks to Intel Corporation for their precious help.
+
+        - We teamed up with Cherry to make Linux the first OS with
+          built-in USB support. Cherry is one of the biggest keyboard
+          makers in the world.

+
+        - Many thanks to ing büro h doran [http://www.ibhdoran.com]!
+          It was almost impossible to get a PC backplate USB connector
+          for the motherboard here at Europe (mine, home-made, was
+          quite lousy :). Now I know where to acquire nice USB stuff!
+
+        - Genius Germany donated a USB mouse to test the mouse boot
+          protocol. They've also donated a F-23 digital joystick and a
+          NetMouse Pro. Thanks! 
+
+        - AVM GmbH Berlin is supporting the development of the Linux
+          USB driver for the AVM ISDN Controller B1 USB. AVM is a

+          and CAPI 2.0-based software. The active design of the AVM B1
+          is open for all OS platforms, including Linux.
+
+        - Thanks to Y-E Data, Inc. for donating their FlashBuster-U
+          USB Floppy Disk Drive, so we could test the bulk transfer
+          code.
+
+        - Many thanks to Logitech for contributing a three axis USB
+          mouse. 
+
+          Logitech designs, manufactures and markets
+          Human Interface Devices, having a long history and
+          experience in making devices such as keyboards, mice,
+          trackballs, cameras, loudspeakers and control devices for
+          gaming and professional use.
+
+          Being a recognized vendor and seller for all these devices,
+          they have donated USB mice, a joystick and a scanner, as a
+          way to acknowledge the importance of Linux and to allow
+          Logitech customers to enjoy support in their favorite
+          operating systems and all Linux users to use Logitech and
+          other USB hardware.
+
+          Logitech is official sponsor of the Linux Conference on
+          Feb. 11th 1999 in Vienna, where we'll will present the
+          current state of the Linux USB effort.
+

+	  serial converter, and the documentation for the device to
+	  allow a driver to be written.
+
+	- Thanks to ADMtek for providing Pegasus and Pegasus II
+	  evaluation boards, specs and valuable advices during
+	  the driver development.
+	
+        And thanks go to (hey! in no particular order :)
