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.

+# Script to apply kernel patches.
+#   usage: patch-kernel [ sourcedir [ patchdir [ stopversion ] [ -acxx ] ] ]
+#     The source directory defaults to /usr/src/linux, and the patch
+#     directory defaults to the current directory.
+# e.g.
+#   scripts/patch-kernel . ..
+#      Update the kernel tree in the current directory using patches in the
+#      directory above to the latest Linus kernel
+#   scripts/patch-kernel . .. -ac
+#      Get the latest Linux kernel and patch it with the latest ac patch
+#   scripts/patch-kernel . .. 2.4.9
+#      Gets standard kernel 2.4.9
+#   scripts/patch-kernel . .. 2.4.9 -ac
+#      Gets 2.4.9 with latest ac patches
+#   scripts/patch-kernel . .. 2.4.9 -ac11
+#      Gets 2.4.9 with ac patch ac11
+#   Note: It uses the patches relative to the Linus kernels, not the
+#   ac to ac relative patches
+#
+# It determines the current kernel version from the top-level Makefile.
+# It then looks for patches for the next sublevel in the patch directory.
+# This is applied using "patch -p1 -s" from within the kernel directory.
+# A check is then made for "*.rej" files to see if the patch was
+# successful.  If it is, then all of the "*.orig" files are removed.

+#
+# Added support for handling multiple types of compression. What includes
+# gzip, bzip, bzip2, zip, compress, and plaintext.
+#
+#       Adam Sulmicki <adam@cfar.umd.edu>, 1st January 1997.
+#
+# Added ability to stop at a given version number
+# Put the full version number (i.e. 2.3.31) as the last parameter
+#       Dave Gilbert <linux@treblig.org>, 11th December 1999.
+
+# Fixed previous patch so that if we are already at the correct version
+# not to patch up.
+#
+# Added -ac option, use -ac or -ac9 (say) to stop at a particular version
+#       Dave Gilbert <linux@treblig.org>, 29th September 2001.
+#
+# Add support for (use of) EXTRAVERSION (to support 2.6.8.x, e.g.);
+# update usage message;
+# fix some whitespace damage;
+# be smarter about stopping when current version is larger than requested;
+#	Randy Dunlap <rdunlap@xenotime.net>, 2004-AUG-18.
+#
+# Add better support for (non-incremental) 2.6.x.y patches;
+# If an ending version number if not specified, the script automatically
+# increments the SUBLEVEL (x in 2.6.x.y) until no more patch files are found;
+# however, EXTRAVERSION (y in 2.6.x.y) is never automatically incremented
+# but must be specified fully.
+#
+# patch-kernel does not normally support reverse patching, but does so when
+# applying EXTRAVERSION (x.y) patches, so that moving from 2.6.11.y to 2.6.11.z
+# is easy and handled by the script (reverse 2.6.11.y and apply 2.6.11.z).
