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.

+# This file has some examples for creating a MIN_CONFIG.
+# (A .config file that is the minimum for a machine to boot, or
+#  to boot and make a network connection.)
+#
+# A MIN_CONFIG is very useful as it is the minimum configuration
+# needed to boot a given machine. You can debug someone else's
+# .config by only setting the configs in your MIN_CONFIG. The closer
+# your MIN_CONFIG is to the true minimum set of configs needed to
+# boot your machine, the closer the config you test with will be
+# to the users config that had the failure.
+#
+# The make_min_config test allows you to create a MIN_CONFIG that
+# is truly the minimum set of configs needed to boot a box.
+#
+# In this example, the final config will reside in
+# ${CONFIG_DIR}/config-new-min and ${CONFIG_DIR}/config-new-min-net.
+# Just move one to the location you have set for MIN_CONFIG.
+#
+# The first test creates a MIN_CONFIG that will be the minimum
+# configuration to boot ${MACHINE} and be able to ssh to it.
+#
+# The second test creates a MIN_CONFIG that will only boot
+# the target and most likely will not let you ssh to it. (Notice
+# how the second test uses the first test's result to continue with.
+# This is because the second test config is a subset of the first).
+#
+# The ${CONFIG_DIR}/config-skip (and -net) will hold the configs
+# that ktest.pl found would not boot the target without them set.
+# The config-new-min holds configs that ktest.pl could not test
+# directly because another config that was needed to boot the box
+# selected them. Sometimes it is possible that this file will hold
+# the true minimum configuration. You can test to see if this is
+# the case by running the boot test with BOOT_TYPE = allnoconfig and
+# setting setting the MIN_CONFIG to ${CONFIG_DIR}/config-skip. If the
+# machine still boots, then you can use the config-skip as your MIN_CONFIG.
+#
+# These tests can run for several hours (and perhaps days).
+# It's OK to kill the test with a Ctrl^C. By restarting without
+# modifying this config, ktest.pl will notice that the config-new-min(-net)
+# exists, and will use that instead as the starting point.
+# The USE_OUTPUT_MIN_CONFIG is set to 1 to keep ktest.pl from asking
+# you if you want to use the OUTPUT_MIN_CONFIG as the starting point.
+# By using the OUTPUT_MIN_CONFIG as the starting point will allow ktest.pl to
+# start almost where it left off.
