Networking changes for 6.9.
Core & protocols ---------------- - Large effort by Eric to lower rtnl_lock pressure and remove locks: - Make commonly used parts of rtnetlink (address, route dumps etc.) lockless, protected by RCU instead of rtnl_lock. - Add a netns exit callback which already holds rtnl_lock, allowing netns exit to take rtnl_lock once in the core instead of once for each driver / callback. - Remove locks / serialization in the socket diag interface. - Remove 6 calls to synchronize_rcu() while holding rtnl_lock. - Remove the dev_base_lock, depend on RCU where necessary. - Support busy polling on a per-epoll context basis. Poll length and budget parameters can be set independently of system defaults. - Introduce struct net_hotdata, to make sure read-mostly global config variables fit in as few cache lines as possible. - Add optional per-nexthop statistics to ease monitoring / debug of ECMP imbalance problems. - Support TCP_NOTSENT_LOWAT in MPTCP. - Ensure that IPv6 temporary addresses' preferred lifetimes are long enough, compared to other configured lifetimes, and at least 2 sec. - Support forwarding of ICMP Error messages in IPSec, per RFC 4301. - Add support for the independent control state machine for bonding per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled control state machine. - Add "network ID" to MCTP socket APIs to support hosts with multiple disjoint MCTP networks. - Re-use the mono_delivery_time skbuff bit for packets which user space wants to be sent at a specified time. Maintain the timing information while traversing veth links, bridge etc. - Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets. - Simplify many places iterating over netdevs by using an xarray instead of a hash table walk (hash table remains in place, for use on fastpaths). - Speed up scanning for expired routes by keeping a dedicated list. - Speed up "generic" XDP by trying harder to avoid large allocations. - Support attaching arbitrary metadata to netconsole messages. Things we sprinkled into general kernel code -------------------------------------------- - Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena). - Rework selftest harness to enable the use of the full range of ksft exit code (pass, fail, skip, xfail, xpass). Netfilter --------- - Allow userspace to define a table that is exclusively owned by a daemon (via netlink socket aliveness) without auto-removing this table when the userspace program exits. Such table gets marked as orphaned and a restarting management daemon can re-attach/regain ownership. - Speed up element insertions to nftables' concatenated-ranges set type. Compact a few related data structures. BPF --- - Add BPF token support for delegating a subset of BPF subsystem functionality from privileged system-wide daemons such as systemd through special mount options for userns-bound BPF fs to a trusted & unprivileged application. - Introduce bpf_arena which is sparse shared memory region between BPF program and user space where structures inside the arena can have pointers to other areas of the arena, and pointers work seamlessly for both user-space programs and BPF programs. - Introduce may_goto instruction that is a contract between the verifier and the program. The verifier allows the program to loop assuming it's behaving well, but reserves the right to terminate it. - Extend the BPF verifier to enable static subprog calls in spin lock critical sections. - Support registration of struct_ops types from modules which helps projects like fuse-bpf that seeks to implement a new struct_ops type. - Add support for retrieval of cookies for perf/kprobe multi links. - Support arbitrary TCP SYN cookie generation / validation in the TC layer with BPF to allow creating SYN flood handling in BPF firewalls. - Add code generation to inline the bpf_kptr_xchg() helper which improves performance when stashing/popping the allocated BPF objects. Wireless -------- - Add SPP (signaling and payload protected) AMSDU support. - Support wider bandwidth OFDMA, as required for EHT operation. Driver API ---------- - Major overhaul of the Energy Efficient Ethernet internals to support new link modes (2.5GE, 5GE), share more code between drivers (especially those using phylib), and encourage more uniform behavior. Convert and clean up drivers. - Define an API for querying per netdev queue statistics from drivers. - IPSec: account in global stats for fully offloaded sessions. - Create a concept of Ethernet PHY Packages at the Device Tree level, to allow parameterizing the existing PHY package code. - Enable Rx hashing (RSS) on GTP protocol fields. Misc ---- - Improvements and refactoring all over networking selftests. - Create uniform module aliases for TC classifiers, actions, and packet schedulers to simplify creating modprobe policies. - Address all missing MODULE_DESCRIPTION() warnings in networking. - Extend the Netlink descriptions in YAML to cover message encapsulation or "Netlink polymorphism", where interpretation of nested attributes depends on link type, classifier type or some other "class type". Drivers ------- - Ethernet high-speed NICs: - Add a new driver for Marvell's Octeon PCI Endpoint NIC VF. - Intel (100G, ice, idpf): - support E825-C devices - nVidia/Mellanox: - support devices with one port and multiple PCIe links - Broadcom (bnxt): - support n-tuple filters - support configuring the RSS key - Wangxun (ngbe/txgbe): - implement irq_domain for TXGBE's sub-interrupts - Pensando/AMD: - support XDP - optimize queue submission and wakeup handling (+17% bps) - optimize struct layout, saving 28% of memory on queues - Ethernet NICs embedded and virtual: - Google cloud vNIC: - refactor driver to perform memory allocations for new queue config before stopping and freeing the old queue memory - Synopsys (stmmac): - obey queueMaxSDU and implement counters required by 802.1Qbv - Renesas (ravb): - support packet checksum offload - suspend to RAM and runtime PM support - Ethernet switches: - nVidia/Mellanox: - support for nexthop group statistics - Microchip: - ksz8: implement PHY loopback - add support for KSZ8567, a 7-port 10/100Mbps switch - PTP: - New driver for RENESAS FemtoClock3 Wireless clock generator. - Support OCP PTP cards designed and built by Adva. - CAN: - Support recvmsg() flags for own, local and remote traffic on CAN BCM sockets. - Support for esd GmbH PCIe/402 CAN device family. - m_can: - Rx/Tx submission coalescing - wake on frame Rx - WiFi: - Intel (iwlwifi): - enable signaling and payload protected A-MSDUs - support wider-bandwidth OFDMA - support for new devices - bump FW API to 89 for AX devices; 90 for BZ/SC devices - MediaTek (mt76): - mt7915: newer ADIE version support - mt7925: radio temperature sensor support - Qualcomm (ath11k): - support 6 GHz station power modes: Low Power Indoor (LPI), Standard Power) SP and Very Low Power (VLP) - QCA6390 & WCN6855: support 2 concurrent station interfaces - QCA2066 support - Qualcomm (ath12k): - refactoring in preparation for Multi-Link Operation (MLO) support - 1024 Block Ack window size support - firmware-2.bin support - support having multiple identical PCI devices (firmware needs to have ATH12K_FW_FEATURE_MULTI_QRTR_ID) - QCN9274: support split-PHY devices - WCN7850: enable Power Save Mode in station mode - WCN7850: P2P support - RealTek: - rtw88: support for more rtw8811cu and rtw8821cu devices - rtw89: support SCAN_RANDOM_SN and SET_SCAN_DWELL - rtlwifi: speed up USB firmware initialization - rtwl8xxxu: - RTL8188F: concurrent interface support - Channel Switch Announcement (CSA) support in AP mode - Broadcom (brcmfmac): - per-vendor feature support - per-vendor SAE password setup - DMI nvram filename quirk for ACEPC W5 Pro Signed-off-by: Jakub Kicinski <kuba@kernel.org> -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE6jPA+I1ugmIBA4hXMUZtbf5SIrsFAmXv0mgACgkQMUZtbf5S IrtgMxAAuRd+WJW++SENr4KxIWhYO1q6Xcxnai43wrNkan9swD24icG8TYALt4f3 yoT6idQvWReAb5JNlh9rUQz8R7E0nJXlvEFn5MtJwcthx2C6wFo/XkJlddlRrT+j c2xGILwLjRhW65LaC0MZ2ECbEERkFz8xcGfK2SWzUgh6KYvPjcRfKFxugpM7xOQK P/Wnqhs4fVRS/Mj/bCcXcO+yhwC121Q3qVeQVjGS0AzEC65hAW87a/kc2BfgcegD EyI9R7mf6criQwX+0awubjfoIdr4oW/8oDVNvUDczkJkbaEVaLMQk9P5x/0XnnVS UHUchWXyI80Q8Rj12uN1/I0h3WtwNQnCRBuLSmtm6GLfCAwbLvp2nGWDnaXiqryW DVKUIHGvqPKjkOOMOVfSvfB3LvkS3xsFVVYiQBQCn0YSs/gtu4CoF2Nty9CiLPbK tTuxUnLdPDZDxU//l0VArZmP8p2JM7XQGJ+JH8GFH4SBTyBR23e0iyPSoyaxjnYn RReDnHMVsrS1i7GPhbqDJWn+uqMSs7N149i0XmmyeqwQHUVSJN3J2BApP2nCaDfy H2lTuYly5FfEezt61NvCE4qr/VsWeEjm1fYlFQ9dFn4pGn+HghyCpw+xD1ZN56DN lujemau5B3kk1UTtAT4ypPqvuqjkRFqpNV2LzsJSk/Js+hApw8Y= =oY52 -----END PGP SIGNATURE----- Merge tag 'net-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Large effort by Eric to lower rtnl_lock pressure and remove locks: - Make commonly used parts of rtnetlink (address, route dumps etc) lockless, protected by RCU instead of rtnl_lock. - Add a netns exit callback which already holds rtnl_lock, allowing netns exit to take rtnl_lock once in the core instead of once for each driver / callback. - Remove locks / serialization in the socket diag interface. - Remove 6 calls to synchronize_rcu() while holding rtnl_lock. - Remove the dev_base_lock, depend on RCU where necessary. - Support busy polling on a per-epoll context basis.

Just two small updates this time: - A series I did to unify the definition of PAGE_SIZE through Kconfig, intended to help with a vdso rework that needs the constant but cannot include the normal kernel headers when building the compat VDSO on arm64 and potentially others. - a patch from Yan Zhao to remove the pfn_to_virt() definitions from a couple of architectures after finding they were both incorrect and entirely unused. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmXwEjQACgkQYKtH/8kJ UifwHxAAqXl6R4cZtjUKxHpQoX7TTtBgWyZ9OID8KYt8V/QN+Jme6EhuGV/5CJ1k 5n30PuDvSKPB9865HfCZgh0BDSzSFo2xtc/bDuqiPHO5deNhXUDKX5MowIs3Pf2J EM1OJYiXG/g9vR19uaHvWVA4I1eJk01+Pl5nZ3DA+n9ZYcnM35+HO7EQcH80FGwz jkjN1HizxDmuMDDKn24hrSt6mVoE54JWyeDvklbY4CbwZbtFbtBJiFv3NWTfaxSf MPR1fopgaAkT0aJzUXOh36qDodyqR2tz4M7ucpRKa6/YlOewDN59tFwgwtun0s74 lLJPBqQ6cT8no1VODNnKPb1M5Jh3uzsF1fuhnU6B06Z+1s7sxxqOli1Q0yrpivYY SCAh6WmiCMhHeP/sxfQHRhhrx9l0gOarXh7s4wRJFp+LAi59NuUTeJotoOfboX4M ozeFgW1Rlr+wORzUargRnQiXMLObC/RFdogLgiBJwa8XOI8bOPZg9JfAUPOwbfa2 37IFZRleu+V2NaBF8rS5wRGI8hVp99XSMjlskKLM/645doqNq1cyR9UO68jb1hhF d5X2+BEaEJTHJbXEQ9YtThpNWYzHXL5dFswVJfHDs+CW1FWi5GVqCufZGzr7xihy uNLlVqXLhjM+hU2dDoS4ZshygxN3b8f2qa+GtlIMBYrLcbcjxd4= =X4Cs -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "Just two small updates this time: - A series I did to unify the definition of PAGE_SIZE through Kconfig, intended to help with a vdso rework that needs the constant but cannot include the normal kernel headers when building the compat VDSO on arm64 and potentially others - a patch from Yan Zhao to remove the pfn_to_virt() definitions from a couple of architectures after finding they were both incorrect and entirely unused" * tag 'asm-generic-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: arch: define CONFIG_PAGE_SIZE_*KB on all architectures arch: simplify architecture specific page size configuration arch: consolidate existing CONFIG_PAGE_SIZE_*KB definitions mm: Remove broken pfn_to_virt() on arch csky/hexagon/openrisc |

SoC: device tree updates for 6.9
There is very little going on with new SoC support this time, all the new chips are variations of others that we already support, and they are all based on ARMv8 cores: - Mediatek MT7981B (Filogic 820) and MT7988A (Filogic 880) are networking SoCs designed to be used in wireless routers, similar to the already supported MT7986A (Filogic 830). - NXP i.MX8DXP is a variant of i.MX8QXP, with two CPU cores less. These are used in many embedded and industrial applications. - Renesas R8A779G2 (R-Car V4H ES2.0) and R8A779H0 (R-Car V4M) are automotive SoCs. - TI J722S is another automotive variant of its K3 family, related to the AM62 series. There are a total of 7 new arm32 machines and 45 arm64 ones, including - Two Android phones based on the old Tegra30 chip - Two machines using Cortex-A53 SoCs from Allwinner, a mini PC and a SoM development board - A set-top box using Amlogic Meson G12A S905X2 - Eight embedded board using NXP i.MX6/8/9 - Three machines using Mediatek network router chips - Ten Chromebooks, all based on Mediatek MT8186 - One development board based on Mediatek MT8395 (Genio 1200) - Seven tablets and phones based on Qualcomm SoCs, most of them from Samsung. - A third development board for Qualcomm SM8550 (Snapdragon 8 Gen 2) - Three variants of the "White Hawk" board for Renesas automotive SoCs - Ten Rockchips RK35xx based machines, including NAS, Tablet, Game console and industrial form factors. - Three evaluation boards for TI K3 based SoCs The other changes are mainly the usual feature additions for existing hardware, cleanups, and dtc compile time fixes. One notable change is the inclusion of PowerVR SGX GPU nodes on TI SoCs. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmXvLwQACgkQYKtH/8kJ Uidkhw/+LjDOIqF8f4+6TBCCS3pFAVSAZxKxlm7L4VhsVOOeGZdspOY57eKZJWqW bVqj+B22UjJSw/9LOrFBNApkV8vk+rR7UfJjzijXM34WB80DC8+s7DbenCHagqR8 fsKCB4tHKTYbBk6EefzyWy7fSA1SFu7hpTg5qWK8XONbGdHnkhbj1aQDbUe7p961 huKGM+2spO+bFs3ljHGymBWywFKtuMTmVzoq16mBZl/bnuIKobm7W2kF+n3NAo+h CMta6J9mBlinBT+VtIg2Xax+KvkjmoitevOmyURxp/33+14A64dafI+RLiSyeqb6 DfeAp9ptrBbVGzYZq2r07WYX9AIBdD2hvdkrtrjOy6JPqtJpWdfA4slYzWCzZfOz O08sV3l7ERggpNkMcTWiwBiuB/y5Hci7SYVeQm8N8bp5PydgNpoo6kNVpnc1e6ri Ug8t/jQYvpkCVHT3ld8PmgpWoZRinKIe6PNmqdg5jUu8aH+m4TNNmHyA2IjBcovj 006FBBGVKp4HlCrGz4t9/XsmKzt+cRxLaX06duoZ93FQknXSzs7j7UDkPhpR07kF yEHjETnfhziyONL2fHZ+ejBoK/9psTFtzbpgMreBJ0mFZM0yvL0c+gcMvDgDD8ho PCp2ohDYpKPoklrTqMLKM7Yjev5bTOdrAJeWoLDWCbgkzVDkyjw= =krkR -----END PGP SIGNATURE----- Merge tag 'soc-dt-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC device tree updates from Arnd Bergmann: "There is very little going on with new SoC support this time, all the new chips are variations of others that we already support, and they are all based on ARMv8 cores: - Mediatek MT7981B (Filogic 820) and MT7988A (Filogic 880) are networking SoCs designed to be used in wireless routers, similar to the already supported MT7986A (Filogic 830). - NXP i.MX8DXP is a variant of i.MX8QXP, with two CPU cores less.

Core x86 changes for v6.9:
- The biggest change is the rework of the percpu code, to support the 'Named Address Spaces' GCC feature, by Uros Bizjak: - This allows C code to access GS and FS segment relative memory via variables declared with such attributes, which allows the compiler to better optimize those accesses than the previous inline assembly code. - The series also includes a number of micro-optimizations for various percpu access methods, plus a number of cleanups of %gs accesses in assembly code. - These changes have been exposed to linux-next testing for the last ~5 months, with no known regressions in this area. - Fix/clean up __switch_to()'s broken but accidentally working handling of FPU switching - which also generates better code. - Propagate more RIP-relative addressing in assembly code, to generate slightly better code. - Rework the CPU mitigations Kconfig space to be less idiosyncratic, to make it easier for distros to follow & maintain these options. - Rework the x86 idle code to cure RCU violations and to clean up the logic. - Clean up the vDSO Makefile logic. - Misc cleanups and fixes. [ Please note that there's a higher number of merge commits in this branch (three) than is usual in x86 topic trees. This happened due to the long testing lifecycle of the percpu changes that involved 3 merge windows, which generated a longer history and various interactions with other core x86 changes that we felt better about to carry in a single branch. ] Signed-off-by: Ingo Molnar <mingo@kernel.org> -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEBpT5eoXrXCwVQwEKEnMQ0APhK1gFAmXvB0gRHG1pbmdvQGtl cm5lbC5vcmcACgkQEnMQ0APhK1jUqRAAqnEQPiabF5acQlHrwviX+cjSobDlqtH5 9q2AQy9qaEHapzD0XMOxvFye6XIvehGOGxSPvk6CoviSxBND8rb56lvnsEZuLeBV Bo5QSIL2x42Zrvo11iPHwgXZfTIusU90sBuKDRFkYBAxY3HK2naMDZe8MAsYCUE9 nwgHF8DDc/NYiSOXV8kosWoWpNIkoK/STyH5bvTQZMqZcwyZ49AIeP1jGZb/prbC e/rbnlrq5Eu6brpM7xo9kELO0Vhd34urV14KrrIpdkmUKytW2KIsyvW8D6fqgDBj NSaQLLcz0pCXbhF+8Nqvdh/1coR4L7Ymt08P1rfEjCsQgb/2WnSAGUQuC5JoGzaj ngkbFcZllIbD9gNzMQ1n4Aw5TiO+l9zxCqPC/r58Uuvstr+K9QKlwnp2+B3Q73Ft rojIJ04NJL6lCHdDgwAjTTks+TD2PT/eBWsDfJ/1pnUWttmv9IjMpnXD5sbHxoiU 2RGGKnYbxXczYdq/ALYDWM6JXpfnJZcXL3jJi0IDcCSsb92xRvTANYFHnTfyzGfw EHkhbF4e4Vy9f6QOkSP3CvW5H26BmZS9DKG0J9Il5R3u2lKdfbb5vmtUmVTqHmAD Ulo5cWZjEznlWCAYSI/aIidmBsp9OAEvYd+X7Z5SBIgTfSqV7VWHGt0BfA1heiVv F/mednG0gGc= =3v4F -----END PGP SIGNATURE----- Merge tag 'x86-core-2024-03-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull core x86 updates from Ingo Molnar: - The biggest change is the rework of the percpu code, to support the 'Named Address Spaces' GCC feature, by Uros Bizjak: - This allows C code to access GS and FS segment relative memory via variables declared with such attributes, which allows the compiler to better optimize those accesses than the previous inline assembly code. - The series also includes a number of micro-optimizations for various percpu access methods, plus a number of cleanups of %gs accesses in assembly code. - These changes have been exposed to linux-next testing for the last ~5 months, with no known regressions in this area. - Fix/clean up __switch_to()'s broken but accidentally working handling of FPU switching - which also generates better code - Propagate more RIP-relative addressing in assembly code, to generate slightly better code - Rework the CPU mitigations Kconfig space to be less idiosyncratic, to make it easier for distros to follow & maintain these options - Rework the x86 idle code to cure RCU violations and to clean up the logic - Clean up the vDSO Makefile logic - Misc cleanups and fixes * tag 'x86-core-2024-03-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (52 commits) x86/idle: Select idle routine only once x86/idle: Let prefer_mwait_c1_over_halt() return bool x86/idle: Cleanup idle_setup() x86/idle: Clean up idle selection x86/idle: Sanitize X86_BUG_AMD_E400 handling sched/idle: Conditionally handle tick broadcast in default_idle_call() x86: Increase brk randomness entropy for 64-bit systems x86/vdso: Move vDSO to mmap region x86/vdso/kbuild: Group non-standard build attributes and primary object file rules together x86/vdso: Fix rethunk patching for vdso-image-{32,64}.o x86/retpoline: Ensure default return thunk isn't used at runtime x86/vdso: Use CONFIG_COMPAT_32 to specify vdso32 x86/vdso: Use $(addprefix ) instead of $(foreach ) x86/vdso: Simplify obj-y addition x86/vdso: Consolidate targets and clean-files x86/bugs: Rename CONFIG_RETHUNK => CONFIG_MITIGATION_RETHUNK x86/bugs: Rename CONFIG_CPU_SRSO => CONFIG_MITIGATION_SRSO x86/bugs: Rename CONFIG_CPU_IBRS_ENTRY => CONFIG_MITIGATION_IBRS_ENTRY x86/bugs: Rename CONFIG_CPU_UNRET_ENTRY => CONFIG_MITIGATION_UNRET_ENTRY x86/bugs: Rename CONFIG_SLS => CONFIG_MITIGATION_SLS ... |

Rust changes for v6.9
Another routine one in terms of features. We got two version upgrades this time, but in terms of lines, 'alloc' changes are not very large. Toolchain and infrastructure: - Upgrade to Rust 1.76.0. This time around, due to how the kernel and Rust schedules have aligned, there are two upgrades in fact. These allow us to remove two more unstable features ('const_maybe_uninit_zeroed' and 'ptr_metadata') from the list, among other improvements. - Mark 'rustc' (and others) invocations as recursive, which fixes a new warning and prepares us for the future in case we eventually take advantage of the Make jobserver. 'kernel' crate: - Add the 'container_of!' macro. - Stop using the unstable 'ptr_metadata' feature by employing the now stable 'byte_sub' method to implement 'Arc::from_raw()'. - Add the 'time' module with a 'msecs_to_jiffies()' conversion function to begin with, to be used by Rust Binder. - Add 'notify_sync()' and 'wait_interruptible_timeout()' methods to 'CondVar', to be used by Rust Binder. - Update integer types for 'CondVar'. - Rename 'wait_list' field to 'wait_queue_head' in 'CondVar'. - Implement 'Display' and 'Debug' for 'BStr'. - Add the 'try_from_foreign()' method to the 'ForeignOwnable' trait. - Add reexports for macros so that they can be used from the right module (in addition to the root). - A series of code documentation improvements, including adding intra-doc links, consistency improvements, typo fixes...

As discussed (see Links), there is some inertia to move to the recent Sphinx versions for the doc build environment. As first step, drop the version constraints and the related comments. As sphinx depends on jinja2, jinja2 is pulled in automatically. So drop that. Then, the sphinx-pre-install script will fail though with: Can't get default sphinx version from ./Documentation/sphinx/requirements.txt at ./scripts/sphinx-pre-install line 305. The script simply expects to parse a version constraint with Sphinx in the requirements.txt. That version is used in the script for suggesting the virtualenv directory name. To suggest a virtualenv directory name, when there is no version given in the requirements.txt, one could try to guess the version that would be downloaded with 'pip install -r Documentation/sphinx/requirements.txt'. However, there seems no simple way to get that version without actually setting up the venv and running pip. So, instead, name the directory with the fixed name 'sphinx_latest'. Finally update the Sphinx build documentation to reflect this directory name change.

coccinelle: semantic patch to check for potential struct_size calls
include/linux/overflow.h includes helper macros intended for calculating sizes of allocations. These macros prevent accidental overflow by saturating at SIZE_MAX. In general when calculating such sizes use of the macros is preferred. Add a semantic patch which can detect code patterns which can be replaced by struct_size. Note that I set the confidence to medium because this patch doesn't make an attempt to ensure that the relevant array is actually a flexible array. The struct_size macro does specifically require a flexible array. In many cases the detected code could be refactored to a flexible array, but this is not always possible (such as if there are multiple over-allocations).

kbuild: mark rustc (and others) invocations as recursive
`rustc` (like Cargo) may take advantage of the jobserver at any time (e.g. for backend parallelism, or eventually frontend too). In the kernel, we call `rustc` with `-Ccodegen-units=1` (and `-Zthreads` is 1 so far), so we do not expect parallelism. However, in the upcoming Rust 1.76.0, a warning is emitted by `rustc` [1] when it cannot connect to the jobserver it was passed (in many cases, but not all: compiling and `--print sysroot` do, but `--version` does not). And given GNU Make always passes the jobserver in the environment variable (even when a line is deemed non-recursive), `rustc` will end up complaining about it (in particular in Make 4.3 where there is only the simple pipe jobserver style). One solution is to remove the jobserver from `MAKEFLAGS`. However, we can mark the lines with calls to `rustc` (and Cargo) as recursive, which looks simpler. This is being documented as a recommendation in `rustc` [2] and allows us to be ready for the time we may use parallelism inside `rustc` (potentially now, if a user passes `-Zthreads`). Thus do so. Similarly, do the same for `rustdoc` and `cargo` calls. Finally, there is one case that the solution does not cover, which is the `$(shell ...)` call we have. Thus, for that one, set an empty `MAKEFLAGS` environment variable.

locking/atomic: scripts: Clarify ordering of conditional atomics
Conditional atomic operations (e.g. cmpxchg()) only provide ordering when the condition holds; when the condition does not hold, the location is not modified and relaxed ordering is provided. Where ordering is needed for failed conditional atomics, it is necessary to use smp_mb__before_atomic() and/or smp_mb__after_atomic(). This is explained tersely in memory-barriers.txt, and is implied but not explicitly stated in the kerneldoc comments for the conditional operations. The lack of an explicit statement has lead to some off-list queries about the ordering semantics of failing conditional operations, so evidently this is confusing. Update the kerneldoc comments to explicitly describe the lack of ordering for failed conditional atomic operations. For most conditional atomic operations, this is written as: | If (${condition}), atomically updates @v to (${new}) with ${desc_order} ordering. | Otherwise, @v is not modified and relaxed ordering is provided. For the try_cmpxchg() operations, this is written as: | If (${condition}), atomically updates @v to @new with ${desc_order} ordering. | Otherwise, @v is not modified, @old is updated to the current value of @v, | and relaxed ordering is provided.

kbuild: Add -Wa,--fatal-warnings to as-instr invocation
Certain assembler instruction tests may only induce warnings from the assembler on an unsupported instruction or option, which causes as-instr to succeed when it was expected to fail. Some tests workaround this limitation by additionally testing that invalid input fails as expected. However, this is fragile if the assembler is changed to accept the invalid input, as it will cause the instruction/option to be unavailable like it was unsupported even when it is. Use '-Wa,--fatal-warnings' in the as-instr macro to turn these warnings into hard errors, which avoids this fragility and makes tests more robust and well formed.

kallsyms: ignore ARMv4 thunks along with others
lld is now able to build ARMv4 and ARMv4T kernels, which means it can generate thunks for those (__ARMv4PILongThunk_*, __ARMv4PILongBXThunk_*) that can interfere with kallsyms table generation since they do not get ignore like the corresponding ARMv5+ ones are: Inconsistent kallsyms data Try "make KALLSYMS_EXTRA_PASS=1" as a workaround Replace the hardcoded list of thunk symbols with a more general regex that covers this one along with future symbols that follow the same pattern.

scripts/kernel-doc: reindent
This file is using an ungodly mixture of 4 spaces, 2-wide tabs, 4-wide tabs, _and_ 8-wide tabs, making it really hard to find good editor settings for working with this file. Bite the bullet and reindent it by hand. I tried using both perltidy and vim, but neither of them were up to the task without changing too much or getting confused about what they were supposed to be doing. I did change a few instances of } else into } else (and same for elsif); the file is again written using both styles, and I left functions which already seemed self-consistent alone. You can verify that this commit only changes whitespace using e.g.: git diff --ignore-all-space --word-diff or to see (only) the instances where newlines were added/removed: git diff --ignore-all-space You can also see the delta from what perltidy would have wanted to do to this file (when asked to only indent it), which isn't that much in the end: perltidy -io -fnl scripts/kernel-doc git diff --no-index scripts/kernel-doc{,.tdy} Signed-off-by: Vegard Nossum <vegard.nossum@oracle.com> Acked-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net> Link: https://lore.kernel.org/r/20240208161705.888385-1-vegard.nossum@oracle.com |

docs: scripts: sphinx-pre-install: Fix building docs with pyyaml package
The Python module pyyaml is required to build the docs, but it is only listed in Documentation/sphinx/requirements.txt and is therefore missing when Sphinx is installed as a package and not via pip/pypi. Add pyyaml as an optional package for multiple distros to fix building the docs if you prefer to install Sphinx as a package.

bpf, scripts: Correct GPL license name
The bpf_doc script refers to the GPL as the "GNU Privacy License".
I strongly suspect that the author wanted to refer to the GNU General
Public License, under which the Linux kernel is released, as, to the
best of my knowledge, there is no license named "GNU Privacy License".
This patch corrects the license name in the script accordingly.

kbuild: rpm-pkg: simplify installkernel %post
The new installkernel application that is now included in systemd-udev package allows installation although destination files are already present in the boot directory of the kernel package, but is failing with the implemented workaround for the old installkernel application from grubby package. For the new installkernel application, as Davide says: <<The %post currently does a shuffling dance before calling installkernel. This isn't actually necessary afaict, and the current implementation ends up triggering downstream issues such as https://github.com/systemd/systemd/issues/29568 This commit simplifies the logic to remove the shuffling. For reference, the original logic was added in commit 3c9c7a14b627("rpm-pkg: add %post section to create initramfs and grub hooks").>> But we need to keep the old behavior as well, because the old installkernel application from grubby package, does not allow this simplification and we need to be backward compatible to avoid issues with the different packages. Mimic Fedora shipping process and store vmlinuz, config amd System.map in the module directory instead of the boot directory. In this way, we will avoid the commented problem for all the cases, because the new destination files are not going to exist in the boot directory of the kernel package. Replace installkernel tool with kernel-install tool, because the latter is more complete. Besides, after installkernel tool execution, check to complete if the correct package files vmlinuz, System.map and config files are present in /boot directory, and if necessary, copy manually for install operation. In this way, take into account if files were not previously copied from /usr/lib/kernel/install.d/* scripts and if the suitable files for the requested package are present (it could be others if the rpm files were replace with a new pacakge with the same release and a different build). Tested with Fedora 38, Fedora 39, RHEL 9, Oracle Linux 9.3, openSUSE Tumbleweed and openMandrive ROME, using dnf/zypper and rpm tools. cc: stable@vger.kernel.org Co-Developed-by: Davide Cavalca <dcavalca@meta.com> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm@redhat.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |
