Pull documentation update from Jonathan Corbet: "Another moderately busy cycle for documentation, including: - The minimum Sphinx requirement has been raised to 2.4.4, following a warning that was added in 6.2 - Some reworking of the Documentation/process front page to, hopefully, make it more useful - Various kernel-doc tweaks to, for example, make it deal properly with __counted_by annotations - We have also restored a warning for documentation of nonexistent structure members that disappeared a while back. That had the delightful consequence of adding some 600 warnings to the docs build. A sustained effort by Randy, Vegard, and myself has addressed almost all of those, bringing the documentation back into sync with the code.

The other six new SoCs are all part of existing arm64 families, but are somewhat more interesting: - Samsung ExynosAutov920 is an automotive chip, and the first one we support based on the Cortex-A78AE core with lockstep mode. - Google gs101 (Tensor G1) is the chip used in a number of Pixel phones, and is grouped with Samsung Exynos here since it is based on the same SoC design, sharing most of its IP blocks with that series. - MediaTek MT8188 is a new chip used for mid-range tablets and Chromebooks, using two Cortex-A78 cores where the older MT8195 had four of them. - Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range phone SoC and the first supported chip based on Cortex-X4, Cortex-A720 and Cortex-A520. - Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest Laptop chip using the custom Oryon cores. - Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on Cortex-A76 and Cortex-A55 In terms of boards, we have - Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs. - Multiple Rockchips mobile gaming systems (Anbernic RG351V, Powkiddy RK2023, Powkiddy X55) along with the Sonoff iHost Smart Home Hub and a few Rockchips SBCs - Some ComXpress boards based on Marvell CN913x, which is the follow-up to Armada 7xxx/8xxx. - Six new industrial/embedded boards based on NXP i.MX8 and i.MX9 - Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer. - Toradex Verdin AM62 Mallow carrier for TI AM62 - Huashan Pi board based on the SophGo CV1812H RISC-V chip - Two boards based on Allwinner H616/H618 - A number of reference boards for various added SoCs from Qualcomm, Mediatek, Google, Samsung, NXP and Spreadtrum As usual, there are cleanups and warning fixes across all platforms as well as added features for several of them" * tag 'soc-dt-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (857 commits) ARM: dts: usr8200: Fix phy registers arm64: dts: intel: minor whitespace cleanup around '=' arm64: dts: socfpga: agilex: drop redundant status arm64: dts: socfpga: agilex: add unit address to soc node arm64: dts: socfpga: agilex: move firmware out of soc node arm64: dts: socfpga: agilex: move FPGA region out of soc node arm64: dts: socfpga: agilex: align pin-controller name with bindings arm64: dts: socfpga: stratix10_swvp: drop unsupported DW MSHC properties arm64: dts: socfpga: stratix10_socdk: align NAND chip name with bindings arm64: dts: socfpga: stratix10: add unit address to soc node arm64: dts: socfpga: stratix10: move firmware out of soc node arm64: dts: socfpga: stratix10: move FPGA region out of soc node arm64: dts: socfpga: stratix10: align pincfg nodes with bindings arm64: dts: socfpga: stratix10: add clock-names to DWC2 USB arm64: dts: socfpga: drop unsupported cdns,page-size and cdns,block-size ARM: dts: socfpga: align NAND controller name with bindings ARM: dts: socfpga: drop unsupported cdns,page-size and cdns,block-size arm64: dts: rockchip: Fix led pinctrl of lubancat 1 arm64: dts: rockchip: correct gpio_pwrctrl1 typo on nanopc-t6 arm64: dts: rockchip: correct gpio_pwrctrl1 typo on rock-5b ...

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "The most interesting thing is probably the networking structs reorganization and a significant amount of changes is around self-tests. Core & protocols: - Analyze and reorganize core networking structs (socks, netdev, netns, mibs) to optimize cacheline consumption and set up build time warnings to safeguard against future header changes This improves TCP performances with many concurrent connections up to 40% - Add page-pool netlink-based introspection, exposing the memory usage and recycling stats. This helps indentify bad PP users and possible leaks - Refine TCP/DCCP source port selection to no longer favor even source port at connect() time when IP_LOCAL_PORT_RANGE is set. This lowers the time taken by connect() for hosts having many active connections to the same destination - Refactor the TCP bind conflict code, shrinking related socket structs - Refactor TCP SYN-Cookie handling, as a preparation step to allow arbitrary SYN-Cookie processing via eBPF - Tune optmem_max for 0-copy usage, increasing the default value to 128KB and namespecifying it - Allow coalescing for cloned skbs coming from page pools, improving RX performances with some common configurations - Reduce extension header parsing overhead at GRO time - Add bridge MDB bulk deletion support, allowing user-space to request the deletion of matching entries - Reorder nftables struct members, to keep data accessed by the datapath first - Introduce TC block ports tracking and use. This allows supporting multicast-like behavior at the TC layer - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and classifiers (RSVP and tcindex) - More data-race annotations - Extend the diag interface to dump TCP bound-only sockets - Conditional notification of events for TC qdisc class and actions - Support for WPAN dynamic associations with nearby devices, to form a sub-network using a specific PAN ID - Implement SMCv2.1 virtual ISM device support - Add support for Batman-avd mulicast packet type BPF: - Tons of verifier improvements: - BPF register bounds logic and range support along with a large test suite - log improvements - complete precision tracking support for register spills - track aligned STACK_ZERO cases as imprecise spilled registers. This improves the verifier "instructions processed" metric from single digit to 50-60% for some programs - support for user's global BPF subprogram arguments with few commonly requested annotations for a better developer experience - support tracking of BPF_JNE which helps cases when the compiler transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the like - several fixes - Add initial TX metadata implementation for AF_XDP with support in mlx5 and stmmac drivers. Two types of offloads are supported right now, that is, TX timestamp and TX checksum offload - Fix kCFI bugs in BPF all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y - Change BPF verifier logic to validate global subprograms lazily instead of unconditionally before the main program, so they can be guarded using BPF CO-RE techniques - Support uid/gid options when mounting bpffs - Add a new kfunc which acquires the associated cgroup of a task within a specific cgroup v1 hierarchy where the latter is identified by its id - Extend verifier to allow bpf_refcount_acquire() of a map value field obtained via direct load which is a use-case needed in sched_ext - Add BPF link_info support for uprobe multi link along with bpftool integration for the latter - Support for VLAN tag in XDP hints - Remove deprecated bpfilter kernel leftovers given the project is developed in user-space (https://github.com/facebook/bpfilter) Misc: - Support for parellel TC self-tests execution - Increase MPTCP self-tests coverage - Updated the bridge documentation, including several so-far undocumented features - Convert all the net self-tests to run in unique netns, to avoid random failures due to conflict and allow concurrent runs - Add TCP-AO self-tests - Add kunit tests for both cfg80211 and mac80211 - Autogenerate Netlink families documentation from YAML spec - Add yml-gen support for fixed headers and recursive nests, the tool can now generate user-space code for all genetlink families for which we have specs - A bunch of additional module descriptions fixes - Catch incorrect freeing of pages belonging to a page pool Driver API: - Rust abstractions for network PHY drivers; do not cover yet the full C API, but already allow implementing functional PHY drivers in rust - Introduce queue and NAPI support in the netdev Netlink interface, allowing complete access to the device <> NAPIs <> queues relationship - Introduce notifications filtering for devlink to allow control application scale to thousands of instances - Improve PHY validation, requesting rate matching information for each ethtool link mode supported by both the PHY and host - Add support for ethtool symmetric-xor RSS hash - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD platform - Expose pin fractional frequency offset value over new DPLL generic netlink attribute - Convert older drivers to platform remove callback returning void - Add support for PHY package MMD read/write New hardware / drivers: - Ethernet: - Octeon CN10K devices - Broadcom 5760X P7 - Qualcomm SM8550 SoC - Texas Instrument DP83TG720S PHY - Bluetooth: - IMC Networks Bluetooth radio Removed: - WiFi: - libertas 16-bit PCMCIA support - Atmel at76c50x drivers - HostAP ISA/PCMCIA style 802.11b driver - zd1201 802.11b USB dongles - Orinoco ISA/PCMCIA 802.11b driver - Aviator/Raytheon driver - Planet WL3501 driver - RNDIS USB 802.11b driver Driver updates: - Ethernet high-speed NICs: - Intel (100G, ice, idpf): - allow one by one port representors creation and removal - add temperature and clock information reporting - add get/set for ethtool's header split ringparam - add again FW logging - adds support switchdev hardware packet mirroring - iavf: implement symmetric-xor RSS hash - igc: add support for concurrent physical and free-running timers - i40e: increase the allowable descriptors - nVidia/Mellanox: - Preparation for Socket-Direct multi-dev netdev.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Add machine variable capacity information to /proc/sysinfo. - Limit the waste of page tables and always align vmalloc area size and base address on segment boundary. - Fix a memory leak when an attempt to register interruption sub class (ISC) for the adjunct-processor (AP) guest failed. - Reset response code AP_RESPONSE_INVALID_GISA to understandable by guest AP_RESPONSE_INVALID_ADDRESS in response to a failed interruption sub class (ISC) registration attempt. - Improve reaction to adjunct-processor (AP) AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts on behalf of a guest. - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) queue device bound to the vfio_ap device driver when the mediated device is attached to a guest, but the queue device is not passed through. - Rework struct ap_card to hold the whole adjunct-processor (AP) card hardware information. As result, all the ugly bit checks are replaced by simple evaluations of the required bit fields. - Improve handling of some weird scenarios between service element (SE) host and SE guest with adjunct-processor (AP) pass-through support. - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return the previous value of the to be changed control register. This is useful if a bit is only changed temporarily and the previous content needs to be restored. - The kernel starts with machine checks disabled and is expected to enable it once trap_init() is called. However the implementation allows machine checks early. Consistently enable it in trap_init() only. - local_mcck_disable() and local_mcck_enable() assume that machine checks are always enabled. Instead implement and use local_mcck_save() and local_mcck_restore() to disable machine checks and restore the previous state. - Modification of floating point control (FPC) register of a traced process using ptrace interface may lead to corruption of the FPC register of the tracing process. Fix this. - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control (FPC) register in vCPU, but may lead to corruption of the FPC register of the host process. Fix this. - Use READ_ONCE() to read a vCPU floating point register value from the memory mapped area. This avoids that, depending on code generation, a different value is tested for validity than the one that is used. - Get rid of test_fp_ctl(), since it is quite subtle to use it correctly. Instead copy a new floating point control register value into its save area and test the validity of the new value when loading it. - Remove superfluous save_fpu_regs() call. - Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines provide the vector facility since many years and the need to make the task structure size dependent on the vector facility does not exist. - Remove the "novx" kernel command line option, as the vector code runs without any problems since many years. - Add the vector facility to the z13 architecture level set (ALS). All hypervisors support the vector facility since many years. This allows compile time optimizations of the kernel. - Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As result, the compiled code will have less runtime checks and less code. - Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C. - Convert the struct subchannel spinlock from pointer to member. * tag 's390-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (24 commits) Revert "s390: update defconfigs" s390/cio: make sch->lock spinlock pointer a member s390: update defconfigs s390/mm: convert pgste locking functions to C s390/fpu: get rid of MACHINE_HAS_VX s390/als: add vector facility to z13 architecture level set s390/fpu: remove "novx" option s390/fpu: remove ARCH_WANTS_DYNAMIC_TASK_STRUCT support KVM: s390: remove superfluous save_fpu_regs() call s390/fpu: get rid of test_fp_ctl() KVM: s390: use READ_ONCE() to read fpc register value KVM: s390: fix setting of fpc register s390/ptrace: handle setting of fpc register correctly s390/nmi: implement and use local_mcck_save() / local_mcck_restore() s390/nmi: consistently enable machine checks in trap_init() s390/ctlreg: return old register contents when changing bits s390/ap: handle outband SE bind state change s390/ap: store TAPQ hwinfo in struct ap_card s390/vfio-ap: fix sysfs status attribute for AP queue devices s390/vfio-ap: improve reaction to response code 07 from PQAP(AQIC) command ...

2024-01-11dt-bindings: power: Clarify wording for wakeup-source propertyMark Hasemeyer1-7/+11
The wording in the current documentation is a little strong. The intention was not to fix any particular interrupt as wakeup capable but leave those details to the device. It wasn't intended to enforce any rules as what can be or can't be a wakeup interrupt. Soften the wording to not mandate that the 'wakeup-source' property be used, and clarify what it means when an interrupt is marked (or not marked) for wakeup.

git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull sysctl updates from Luis Chamberlain: "To help make the move of sysctls out of kernel/sysctl.c not incur a size penalty sysctl has been changed to allow us to not require the sentinel, the final empty element on the sysctl array. Joel Granados has been doing all this work. In the v6.6 kernel we got the major infrastructure changes required to support this. For v6.7 we had all arch/ and drivers/ modified to remove the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only. The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches are still being reviewed. After that we then can expect also the removal of the no longer needed check for procname == NULL. Let us recap the purpose of this work: - this helps reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array - the extra 64-byte penalty is no longer inncurred now when we move sysctls out from kernel/sysctl.c to their own files Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further work by Thomas Weißschuh with the constificatin of the struct ctl_table. Due to Joel Granados's work, and to help bring in new blood, I have suggested for him to become a maintainer and he's accepted. So for v6.9-rc1 I look forward to seeing him sent you a pull request for further sysctl changes. This also removes Iurii Zaikin as a maintainer as he has moved on to other projects and has had no time to help at all" * tag 'sysctl-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: sysctl: remove struct ctl_path sysctl: delete unused define SYSCTL_PERM_EMPTY_DIR coda: Remove the now superfluous sentinel elements from ctl_table array sysctl: Remove the now superfluous sentinel elements from ctl_table array fs: Remove the now superfluous sentinel elements from ctl_table array cachefiles: Remove the now superfluous sentinel element from ctl_table array sysclt: Clarify the results of selftest run sysctl: Add a selftest for handling empty dirs sysctl: Fix out of bounds access for empty sysctl registers MAINTAINERS: Add Joel Granados as co-maintainer for proc sysctl MAINTAINERS: remove Iurii Zaikin from proc sysctl

Pull bcachefs updates from Kent Overstreet: - btree write buffer rewrite: instead of adding keys to the btree write buffer at transaction commit time, we now journal them with a different journal entry type and copy them from the journal to the write buffer just prior to journal write. This reduces the number of atomic operations on shared cachelines in the transaction commit path and is a signicant performance improvement on some workloads: multithreaded 4k random writes went from ~650k iops to ~850k iops. - Bring back optimistic spinning for six locks: the new implementation doesn't use osq locks; instead we add to the lock waitlist as normal, and then spin on the lock_acquired bit in the waitlist entry, _not_ the lock itself. - New ioctls: - BCH_IOCTL_DEV_USAGE_V2, which allows for new data types - BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of fsck but without mounting: useful for transparently using the kernel version of fsck from 'bcachefs fsck' when the kernel version is a better match for the on disk filesystem. - BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported yet, but the passes that are supported are fully featured - errors may be corrected as normal. The new ioctls use the new 'thread_with_file' abstraction for kicking off a kthread that's tied to a file descriptor returned to userspace via the ioctl. - btree_paths within a btree_trans are now dynamically growable, instead of being limited to 64. This is important for the check_directory_structure phase of fsck, and also fixes some issues we were having with btree path overflow in the reflink btree. - Trigger refactoring; prep work for the upcoming disk space accounting rewrite - Numerous bugfixes :) * tag 'bcachefs-2024-01-10' of https://evilpiepirate.org/git/bcachefs: (226 commits) bcachefs: eytzinger0_find() search should be const bcachefs: move "ptrs not changing" optimization to bch2_trigger_extent() bcachefs: fix simulateously upgrading & downgrading bcachefs: Restart recovery passes more reliably bcachefs: bch2_dump_bset() doesn't choke on u64s == 0 bcachefs: improve checksum error messages bcachefs: improve validate_bset_keys() bcachefs: print sb magic when relevant bcachefs: __bch2_sb_field_to_text() bcachefs: %pg is banished bcachefs: Improve would_deadlock trace event bcachefs: fsck_err()s don't need to manually check c->sb.version anymore bcachefs: Upgrades now specify errors to fix, like downgrades bcachefs: no thread_with_file in userspace bcachefs: Don't autofix errors we can't fix bcachefs: add missing bch2_latency_acct() call bcachefs: increase max_active on io_complete_wq bcachefs: add time_stats for btree_node_read_done() bcachefs: don't clear accessed bit in btree node fill bcachefs: Add an option to control btree node prefetching ...
