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.

+|
+|	Input: Double-extended number X in location pointed to
+|		by address register a0.
+|
+|	Output: The function values are returned in Fp0.
+|
+|	Accuracy and Monotonicity: The returned result is within 2 ulps in
+|		64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|		result is subsequently rounded to double precision. The
+|		result is provably monotonic in double precision.
+|
+|	Speed: The program stwotox takes approximately 190 cycles and the
+|		program stentox takes approximately 200 cycles.

+|	Algorithm:
+|
+|	twotox
+|	1. If |X| > 16480, go to ExpBig.
+|
+|	2. If |X| < 2**(-70), go to ExpSm.
+|
+|	3. Decompose X as X = N/64 + r where |r| <= 1/128. Furthermore
+|		decompose N as
+|		 N = 64(M + M') + j,  j = 0,1,2,...,63.
+|
+|	4. Overwrite r := r * log2. Then
+|		2**X = 2**(M') * 2**(M) * 2**(j/64) * exp(r).
+|		Go to expr to compute that expression.
+|
+|	tentox
+|	1. If |X| > 16480*log_10(2) (base 10 log of 2), go to ExpBig.
+|
+|	2. If |X| < 2**(-70), go to ExpSm.
+|
+|	3. Set y := X*log_2(10)*64 (base 2 log of 10). Set
+|		N := round-to-int(y). Decompose N as
+|		 N = 64(M + M') + j,  j = 0,1,2,...,63.
+|
+|	4. Define r as
+|		r := ((X - N*L1)-N*L2) * L10
+|		where L1, L2 are the leading and trailing parts of log_10(2)/64
+|		and L10 is the natural log of 10. Then
+|		10**X = 2**(M') * 2**(M) * 2**(j/64) * exp(r).
+|		Go to expr to compute that expression.
+|
+|	expr
+|	1. Fetch 2**(j/64) from table as Fact1 and Fact2.
+|
+|	2. Overwrite Fact1 and Fact2 by
+|		Fact1 := 2**(M) * Fact1
+|		Fact2 := 2**(M) * Fact2
+|		Thus Fact1 + Fact2 = 2**(M) * 2**(j/64).
+|
+|	3. Calculate P where 1 + P approximates exp(r):
+|		P = r + r*r*(A1+r*(A2+...+r*A5)).
+|
+|	4. Let AdjFact := 2**(M'). Return
+|		AdjFact * ( Fact1 + ((Fact1*P) + Fact2) ).
