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.

+68060 SOFTWARE PACKAGE (Kernel version) SIMPLE TESTS
+-----------------------------------------------------
+
+The files itest.sa and ftest.sa contain simple tests to check
+the state of the 68060ISP and 68060FPSP once they have been installed.
+
+Release file format:
+--------------------
+The release files itest.sa and ftest.sa are essentially
+hexadecimal images of the actual tests. This format is the
+ONLY format that will be supported. The hex images were created
+by assembling the source code and then converting the resulting
+binary output images into ASCII text files. The hexadecimal
+numbers are listed using the Motorola Assembly syntax assembler
+directive "dc.l" (define constant longword). The files can be
+converted to other assembly syntaxes by using any word processor
+with a global search and replace function.
+
+To assist in assembling and linking these modules with other modules,
+the installer should add symbolic labels to the top of the files.
+This will allow the calling routines to access the entry points
+of these packages.
+
+The source code itest.s and ftest.s have been included but only
+for documentation purposes.
+
+Release file structure:
+-----------------------
+
+(top of module)
+	-----------------
+	|		| - 128 byte-sized section
+   (1)  |   Call-Out	| - 4 bytes per entry (user fills these in)
+	|		|
+	-----------------
+	|		| - 8 bytes per entry
+   (2)  | Entry Point	| - user does "bsr" or "jsr" to this address
+	|		|
+	-----------------
+	|		| - code section
+   (3)  ~		~
+	|		|
+	-----------------
+(bottom of module)
+
+The first section of this module is the "Call-out" section. This section
+is NOT INCLUDED in {i,f}test.sa (an example "Call-out" section is provided at
+the end of this file). The purpose of this section is to allow the test
+routines to reference external printing functions that must be provided
+by the host operating system. This section MUST be exactly 128 bytes in
+size. There are 32 fields, each 4 bytes in size. Each field corresponds
+to a function required by the test packages (these functions and their
+location are listed in "68060{ISP,FPSP}-TEST call-outs" below). Each field
+entry should contain the address of the corresponding function RELATIVE to
+the starting address of the "call-out" section. The "Call-out" section must
+sit adjacent to the {i,f}test.sa image in memory. Since itest.sa and ftest.sa
+are individual tests, they each require their own "Call-out" sections.
+
+The second section, the "Entry-point" section, is used by external routines
+to access the test routines. Since the {i,f}test.sa hex files contain
+no symbol names, this section contains function entry points that are fixed
+with respect to the top of the package. The currently defined entry-points
+are listed in section "68060{ISP,FPSP}-TEST entry points" below. A calling
+routine would simply execute a "bsr" or "jsr" that jumped to the selected
+function entry-point.
+
+For example, to run the 060ISP test, write a program that includes the
+itest.sa data and execute something similar to:
+
+	bsr	_060ISP_TEST+128+0
+
+(_060ISP_TEST is the starting address of the "Call-out" section; the "Call-out"
+section is 128 bytes long; and the 68060ISP test entry point is located
+0 bytes from the top of the "Entry-point" section.)
+
+The third section is the code section. After entering through an "Entry-point",
+the entry code jumps to the appropriate test code within the code section.
+
+68060ISP-TEST Call-outs:
+------------------------
+0x0: _print_string()
+0x4: _print_number()
+
+68060FPSP-TEST Call-outs:
+-------------------------
+0x0: _print_string()
+0x4: _print_number()
+
+The test packages call _print_string() and _print_number()
+as subroutines and expect the main program to print a string
+or a number to a file or to the screen.
+In "C"-like fashion, the test program calls:
+
+	print_string("Test passed");
+
+		or
+
+	print_number(20);
+
+For _print_string(), the test programs pass a longword address
+of the string on the stack. For _print_number(), the test programs pass
+a longword number to be printed.
+
+For debugging purposes, after the main program performs a "print"
+for a test package, it should flush the output so that it's not
+buffered. In this way, if the test program crashes, at least the previous
+statements printed will be seen.
+
+68060ISP-TEST Entry-points:
+---------------------------
+0x0: integer test
+
+68060FPSP-TEST Entry-points:
+----------------------------
+0x00: main fp test
+0x08: FP unimplemented test
+0x10: FP enabled snan/operr/ovfl/unfl/dz/inex
+
+The floating-point unit test has 3 entry points which will require
+3 different calls to the package if each of the three following tests
+is desired:
+
+main fp test: tests (1) unimp effective address exception
+		    (2) unsupported data type exceptions
+		    (3) non-maskable overflow/underflow exceptions
+
+FP unimplemented: tests FP unimplemented exception. this one is
+		  separate from the previous tests for systems that don't
+		  want FP unimplemented instructions.
+
+FP enabled: tests enabled snan/operr/ovfl/unfl/dz/inex.
+	    basically, it enables each of these exceptions and forces
+	    each using an implemented FP instruction. this process
+	    exercises _fpsp_{snan,operr,ovfl,unfl,dz,inex}() and
+	    _real_{snan,operr,ovfl,unfl,dz,inex}(). the test expects
+	    _real_XXXX() to do nothing except clear the exception
+	    and "rte". if a system's _real_XXXX() handler creates an
+	    alternate result, the test will print "failed" but this
+	    is acceptable.
+
+Miscellaneous:
+--------------
+Again, itest.sa and ftest.sa are simple tests and do not thoroughly
+test all 68060SP connections. For example, they do not test connections
+to _real_access(), _real_trace(), _real_trap(), etc. because these
+will be system-implemented several different ways and the test packages
+must remain system independent.
+
+Example test package set-up:
+----------------------------
+_print_str:
+	.			# provided by system
+	rts
+
+_print_num:
+	.			# provided by system
+	rts
