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（統一碼）支持
+======================
+
+	（英文版）上次更新：2005-01-17，版本號 1.4
+
+此文檔由H. Peter Anvin <unicode@lanana.org>管理，是Linux註冊名稱與編號管理局
+（Linux Assigned Names And Numbers Authority，LANANA）項目的一部分。
+現行版本請見：
+
+	http://www.lanana.org/docs/unicode/admin-guide/unicode.rst
+
+簡介
+-----
+
+Linux內核代碼已被重寫以使用Unicode來將字符映射到字體。下載一個Unicode到字體
+（Unicode-to-font）表，八位字符集與UTF-8模式都將改用此字體來顯示。
+
+這微妙地改變了八位字符表的語義。現在的四個字符表是：
+
+=============== =============================== ================
+映射代號        映射名稱                        Escape代碼 (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
+=============== =============================== ================
+
+特別是 ESC ( U 不再是「直通字體」，因爲字體可能與IBM字符集完全不同。
+例如，即使加載了一個Latin-1字體，也允許使用塊圖形（block graphics）。
+
+請注意，儘管這些代碼與ISO 2022類似，但這些代碼及其用途都與ISO 2022不匹配；
+Linux有兩個八位代碼（G0和G1），而ISO 2022有四個七位代碼（G0-G3）。
+
+根據Unicode標準/ISO 10646，U+F000到U+F8FF被保留用於作業系統範圍內的分配
+（Unicode標準將其稱爲「團體區域（Corporate Zone）」，因爲這對於Linux是不準確
+的，所以我們稱之爲「Linux區域」）。選擇U+F000作爲起點，因爲它允許直接映射
+區域以2的大倍數開始（以防需要1024或2048個字符的字體）。這就留下U+E000到
+U+EFFF作爲最終用戶區。
+
+[v1.2]：Unicodes範圍從U+F000到U+F7FF已經被硬編碼爲直接映射到加載的字體，
+繞過了翻譯表。用戶定義的映射現在默認爲U+F000到U+F0FF，模擬前述行爲。實際上，
+此範圍可能較短；例如，vgacon只能處理256字符（U+F000..U+F0FF）或512字符
+（U+F000..U+F1FF）字體。
+
+Linux 區域中定義的實際字符
+---------------------------
+
+此外，還定義了Unicode 1.1.4中不存在的以下字符；這些字符由DEC VT圖形映射使用。
+[v1.2]此用法已過時，不應再使用；請參見下文。
+
+====== ======================================
+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字符矩陣，這些字符在DEC VT圖形字符集中形成一個平滑的過渡。
+我省略了掃描5行，因爲它也被用作塊圖形字符，因此被編碼爲U+2500 FORMS LIGHT
+HORIZONTAL。
+
+[v1.3]：這些字符已正式添加到Unicode 3.2.0中；它們在U+23BA、U+23BB、U+23BC、
+U+23BD處添加。Linux現在使用新值。
+
+[v1.2]：添加了以下字符來表示常見的鍵盤符號，這些符號不太可能被添加到Unicode
+中，因爲它們非常討厭地取決於特定供應商。當然，這是糟糕設計的一個好例子。
+
+====== ======================================
+U+F810 KEYBOARD SYMBOL FLYING FLAG
+U+F811 KEYBOARD SYMBOL PULLDOWN MENU
+U+F812 KEYBOARD SYMBOL OPEN APPLE
+U+F813 KEYBOARD SYMBOL SOLID APPLE
+====== ======================================
+
+克林貢（Klingon）語支持
+------------------------
+
+1996年，Linux是世界上第一個添加對人工語言克林貢支持的作業系統，克林貢是由
+Marc Okrand爲《星際迷航》電視連續劇創造的。這種編碼後來被徵募Unicode註冊表
+（ConScript Unicode Registry，CSUR）採用，並建議（但最終被拒絕）納入Unicode
+平面一。不過，它仍然是Linux區域中的Linux/CSUR私有分配。
+
+這種編碼已經得到克林貢語言研究所（Klingon Language Institute）的認可。
+有關更多信息，請聯繫他們：
+
+	http://www.kli.org/
+
+由於Linux CZ開頭部分的字符大多是dingbats/symbols/forms類型，而且這是一種
+語言，因此根據標準Unicode慣例，我將它放置在16單元的邊界上。
+
+.. note::
+
+  這個範圍現在由徵募Unicode註冊表正式管理。規範性引用文件爲：
+
+	https://www.evertype.com/standards/csur/klingon.html
+
+克林貢語有一個26個字符的字母表，一個10位數的位置數字書寫系統，從左到右
+，從上到下書寫。
+
+克林貢字母的幾種字形已經被提出。但是由於這組符號看起來始終是一致的，只有實際
+的形狀不同，因此按照標準Unicode慣例，這些差異被認爲是字體變體。

+其他虛構和人工字母
+-------------------
+
+自從分配了克林貢Linux Unicode塊之後，John Cowan <jcowan@reutershealth.com>
+和 Michael Everson <everson@evertype.com> 建立了一個虛構和人工字母的註冊表。
+徵募Unicode註冊表請訪問：
+
+	https://www.evertype.com/standards/csur/
+
+所使用的範圍位於最終用戶區域的低端，因此無法進行規範化分配，但建議希望對虛構
+字母進行編碼的人員使用這些代碼，以實現互操作性。對於克林貢語，CSUR採用了Linux
+編碼。CSUR的人正在推動將Tengwar和Cirth添加到Unicode平面一；將克林貢添加到
+Unicode平面一被拒絕，因此上述編碼仍然是官方的。
