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.

+Unicode（统一码）支持
+======================
+
+	（英文版）上次更新：2005-01-17，版本号 1.4
+
+此文档由H. Peter Anvin <unicode@lanana.org>管理，是Linux注册名称与编号管理局
+（Linux Assigned Names And Numbers Authority，LANANA）项目的一部分。
+现行版本请见：
+
+	http://www.lanana.org/docs/unicode/admin-guide/unicode.rst
+
+简介
+-----
+
+Linux内核代码已被重写以使用Unicode来将字符映射到字体。下载一个Unicode到字体
+（Unicode-to-font）表，八位字符集与UTF-8模式都将改用此字体来显示。
+
+这微妙地改变了八位字符表的语义。现在的四个字符表是：
+
+=============== =============================== ================
+映射代号        映射名称                        Escape代码 (G0)
+=============== =============================== ================
+LAT1_MAP        Latin-1 (ISO 8859-1)            ESC ( B
+GRAF_MAP        DEC VT100 pseudographics        ESC ( 0
+IBMPC_MAP       IBM code page 437               ESC ( U
+USER_MAP        User defined                    ESC ( K
+=============== =============================== ================
+
+特别是 ESC ( U 不再是“直通字体”，因为字体可能与IBM字符集完全不同。
+例如，即使加载了一个Latin-1字体，也允许使用块图形（block graphics）。
+
+请注意，尽管这些代码与ISO 2022类似，但这些代码及其用途都与ISO 2022不匹配；
+Linux有两个八位代码（G0和G1），而ISO 2022有四个七位代码（G0-G3）。
+
+根据Unicode标准/ISO 10646，U+F000到U+F8FF被保留用于操作系统范围内的分配
+（Unicode标准将其称为“团体区域（Corporate Zone）”，因为这对于Linux是不准确
+的，所以我们称之为“Linux区域”）。选择U+F000作为起点，因为它允许直接映射
+区域以2的大倍数开始（以防需要1024或2048个字符的字体）。这就留下U+E000到
+U+EFFF作为最终用户区。
+
+[v1.2]：Unicodes范围从U+F000到U+F7FF已经被硬编码为直接映射到加载的字体，
+绕过了翻译表。用户定义的映射现在默认为U+F000到U+F0FF，模拟前述行为。实际上，
+此范围可能较短；例如，vgacon只能处理256字符（U+F000..U+F0FF）或512字符
+（U+F000..U+F1FF）字体。
+
+Linux 区域中定义的实际字符
+---------------------------
+
+此外，还定义了Unicode 1.1.4中不存在的以下字符；这些字符由DEC VT图形映射使用。
+[v1.2]此用法已过时，不应再使用；请参见下文。
+
+====== ======================================
+U+F800 DEC VT GRAPHICS HORIZONTAL LINE SCAN 1
+U+F801 DEC VT GRAPHICS HORIZONTAL LINE SCAN 3
+U+F803 DEC VT GRAPHICS HORIZONTAL LINE SCAN 7
+U+F804 DEC VT GRAPHICS HORIZONTAL LINE SCAN 9
+====== ======================================
+
+DEC VT220使用6x10字符矩阵，这些字符在DEC VT图形字符集中形成一个平滑的过渡。
+我省略了扫描5行，因为它也被用作块图形字符，因此被编码为U+2500 FORMS LIGHT
+HORIZONTAL。
+
+[v1.3]：这些字符已正式添加到Unicode 3.2.0中；它们在U+23BA、U+23BB、U+23BC、
+U+23BD处添加。Linux现在使用新值。
+
+[v1.2]：添加了以下字符来表示常见的键盘符号，这些符号不太可能被添加到Unicode
+中，因为它们非常讨厌地取决于特定供应商。当然，这是糟糕设计的一个好例子。
+
+====== ======================================
+U+F810 KEYBOARD SYMBOL FLYING FLAG
+U+F811 KEYBOARD SYMBOL PULLDOWN MENU
+U+F812 KEYBOARD SYMBOL OPEN APPLE
+U+F813 KEYBOARD SYMBOL SOLID APPLE
+====== ======================================
+
+克林贡（Klingon）语支持
+------------------------
+
+1996年，Linux是世界上第一个添加对人工语言克林贡支持的操作系统，克林贡是由
+Marc Okrand为《星际迷航》电视连续剧创造的。这种编码后来被征募Unicode注册表
+（ConScript Unicode Registry，CSUR）采用，并建议（但最终被拒绝）纳入Unicode
+平面一。不过，它仍然是Linux区域中的Linux/CSUR私有分配。
+
+这种编码已经得到克林贡语言研究所（Klingon Language Institute）的认可。
+有关更多信息，请联系他们：
+
+	http://www.kli.org/
+
+由于Linux CZ开头部分的字符大多是dingbats/symbols/forms类型，而且这是一种
+语言，因此根据标准Unicode惯例，我将它放置在16单元的边界上。
+
+.. note::
+
+  这个范围现在由征募Unicode注册表正式管理。规范性引用文件为：
+
+	https://www.evertype.com/standards/csur/klingon.html
+
+克林贡语有一个26个字符的字母表，一个10位数的位置数字书写系统，从左到右
+，从上到下书写。
+
+克林贡字母的几种字形已经被提出。但是由于这组符号看起来始终是一致的，只有实际
+的形状不同，因此按照标准Unicode惯例，这些差异被认为是字体变体。

+
+其他虚构和人工字母
+-------------------
+
+自从分配了克林贡Linux Unicode块之后，John Cowan <jcowan@reutershealth.com>
+和 Michael Everson <everson@evertype.com> 建立了一个虚构和人工字母的注册表。
+征募Unicode注册表请访问：
+
+	https://www.evertype.com/standards/csur/
+
+所使用的范围位于最终用户区域的低端，因此无法进行规范化分配，但建议希望对虚构
+字母进行编码的人员使用这些代码，以实现互操作性。对于克林贡语，CSUR采用了Linux
+编码。CSUR的人正在推动将Tengwar和Cirth添加到Unicode平面一；将克林贡添加到
+Unicode平面一被拒绝，因此上述编码仍然是官方的。
