Pull networking updates from Jakub Kicinski: "Core & protocols: - Complete rework of garbage collection of AF_UNIX sockets. AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code: - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter: - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step. BPF: - Add eBPF JIT for ARCv2 CPUs. - Support attaching kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. "Session mode" is a common use-case for tetragon and bpftrace. - Add the ability to specify and retrieve BPF cookie for raw tracepoint programs in order to ease migration from classic to raw tracepoints. - Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and implement support in x86, ARM64 and RISC-V JITs. This allows inlining functions which need to access per-CPU state. - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various atomics in bpf_arena which can be JITed as a single x86 instruction. Support BPF arena on ARM64. - Add a new bpf_wq API for deferring events and refactor process-context bpf_timer code to keep common code where possible. - Harden the BPF verifier's and/or/xor value tracking. - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs. - Support bpf_tail_call_static() helper for BPF programs with GCC 13. - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF program to have code sections where preemption is disabled. Driver API: - Skip software TC processing completely if all installed rules are marked as HW-only, instead of checking the HW-only flag rule by rule. - Add support for configuring PoE (Power over Ethernet), similar to the already existing support for PoDL (Power over Data Line) config. - Initial bits of a queue control API, for now allowing a single queue to be reset without disturbing packet flow to other queues. - Common (ethtool) statistics for hardware timestamping. Tests and tooling: - Remove the need to create a config file to run the net forwarding tests so that a naive "make run_tests" can exercise them. - Define a method of writing tests which require an external endpoint to communicate with (to send/receive data towards the test machine). Add a few such tests. - Create a shared code library for writing Python tests. Expose the YAML Netlink library from tools/ to the tests for easy Netlink access. - Move netfilter tests under net/, extend them, separate performance tests from correctness tests, and iron out issues found by running them "on every commit". - Refactor BPF selftests to use common network helpers. - Further work filling in YAML definitions of Netlink messages for: nftables, team driver, bonding interfaces, vlan interfaces, VF info, TC u32 mark, TC police action. - Teach Python YAML Netlink to decode attribute policies. - Extend the definition of the "indexed array" construct in the specs to cover arrays of scalars rather than just nests. - Add hyperlinks between definitions in generated Netlink docs. Drivers: - Make sure unsupported flower control flags are rejected by drivers, and make more drivers report errors directly to the application rather than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen). - Ethernet high-speed NICs: - Broadcom (bnxt): - support multiple RSS contexts and steering traffic to them - support XDP metadata - make page pool allocations more NUMA aware - Intel (100G, ice, idpf): - extract datapath code common among Intel drivers into a library - use fewer resources in switchdev by sharing queues with the PF - add PFCP filter support - add Ethernet filter support - use a spinlock instead of HW lock in PTP clock ops - support 5 layer Tx scheduler topology - nVidia/Mellanox: - 800G link modes and 100G SerDes speeds - per-queue IRQ coalescing configuration - Marvell Octeon: - support offloading TC packet mark action - Ethernet NICs consumer, embedded and virtual: - stop lying about skb->truesize in USB Ethernet drivers, it messes up TCP memory calculations - Google cloud vNIC: - support changing ring size via ethtool - support ring reset using the queue control API - VirtIO net: - expose flow hash from RSS to XDP - per-queue statistics - add selftests - Synopsys (stmmac): - support controllers which require an RX clock signal from the MII bus to perform their hardware initialization - TI: - icssg_prueth: support ICSSG-based Ethernet on AM65x SR1.0 devices - icssg_prueth: add SW TX / RX Coalescing based on hrtimers - cpsw: minimal XDP support - Renesas (ravb): - support describing the MDIO bus - Realtek (r8169): - add support for RTL8168M - Microchip Sparx5: - matchall and flower actions mirred and redirect - Ethernet switches: - nVidia/Mellanox: - improve events processing performance - Marvell: - add support for MV88E6250 family internal PHYs - Microchip: - add DCB and DSCP mapping support for KSZ switches - vsc73xx: convert to PHYLINK - Realtek: - rtl8226b/rtl8221b: add C45 instances and SerDes switching - Many driver changes related to PHYLIB and PHYLINK deprecated API cleanup - Ethernet PHYs: - Add a new driver for Airoha EN8811H 2.5 Gigabit PHY. - micrel: lan8814: add support for PPS out and external timestamp trigger - WiFi: - Disable Wireless Extensions (WEXT) in all Wi-Fi 7 devices drivers.

Merge tag 'firewire-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire updates from Takashi Sakamoto: "During the development period of v6.8 kernel, it became evident that there was a lack of helper utilities to trace the initial state of bus, while investigating certain PHYs compliant with different versions of IEEE 1394 specification. This series of changes includes the addition of tracepoints events, provided by 'firewire' subsystem. These events enable tracing of how firewire core functions during bus reset and asynchronous communication over IEEE 1394 bus. When implementing the tracepoints events, it was found that the existing serialization and deserialization helpers for several types of asynchronous packets are scattered across both firewire-core and firewire-ohci kernel modules. A set of inline functions is newly added to address it, along with some KUnit tests, serving as the foundation for the tracepoints events. This renders the dispersed code obsolete. The remaining changes constitute the final steps in phasing out the usage of deprecated PCI MSI APIs, in continuation from the previous version" * tag 'firewire-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: (29 commits) firewire: obsolete usage of *-objs in Makefile for KUnit test firewire: core: remove flag and width from u64 formats of tracepoints events firewire: core: fix type of timestamp for async_inbound_template tracepoints events firewire: core: add tracepoint event for handling bus reset Revert "firewire: core: option to log bus reset initiation" firewire: core: add tracepoints events for initiating bus reset firewire: ohci: obsolete OHCI_PARAM_DEBUG_BUSRESETS from debug module parameter firewire: ohci: add bus-reset event for initial set of handled irq firewire: core: add tracepoints event for asynchronous inbound phy packet firewire: core/cdev: add tracepoints events for asynchronous phy packet firewire: core: add tracepoints events for asynchronous outbound response firewire: core: add tracepoint event for asynchronous inbound request firewire: core: add tracepoints event for asynchronous inbound response firewire: core: add tracepoints events for asynchronous outbound request firewire: core: add support for Linux kernel tracepoints firewire: core: replace local macros with common inline functions for isochronous packet header firewire: core: add common macro to serialize/deserialize isochronous packet header firewire: core: obsolete tcode check macros with inline functions firewire: ohci: replace hard-coded values with common macros firewire: ohci: replace hard-coded values with inline functions for asynchronous packet header ...

Merge tag 'for-6.10/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Add a dm-crypt optional "high_priority" flag that enables the crypt workqueues to use WQ_HIGHPRI. - Export dm-crypt workqueues via sysfs (by enabling WQ_SYSFS) to allow for improved visibility and controls over IO and crypt workqueues. - Fix dm-crypt to no longer constrain max_segment_size to PAGE_SIZE. This limit isn't needed given that the block core provides late bio splitting if bio exceeds underlying limits (e.g. max_segment_size). - Fix dm-crypt crypt_queue's use of WQ_UNBOUND to not use WQ_CPU_INTENSIVE because it is meaningless with WQ_UNBOUND. - Fix various issues with dm-delay target (ranging from a resource teardown fix, a fix for hung task when using kthread mode, and other improvements that followed from code inspection). * tag 'for-6.10/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm-delay: remove timer_lock dm-delay: change locking to avoid contention dm-delay: fix max_delay calculations dm-delay: fix hung task introduced by kthread mode dm-delay: fix workqueue delay_timer race dm-crypt: don't set WQ_CPU_INTENSIVE for WQ_UNBOUND crypt_queue dm: use queue_limits_set dm-crypt: stop constraining max_segment_size to PAGE_SIZE dm-crypt: export sysfs of all workqueues dm-crypt: add the optional "high_priority" flag

Pull dlm updates from David Teigland: "This set includes some small fixes, and some big internal changes: - Fix a long standing race between the unlock callback for the last lkb struct, and removing the rsb that became unused after the final unlock. This could lead different nodes to inconsistent info about the rsb master node. - Remove unnecessary refcounting on callback structs, returning to the way things were done in the past. - Do message processing in softirq context. This allows dlm messages to be cleared more quickly and efficiently, reducing long lists of incomplete requests. A future change to run callbacks directly from this context will make this more effective. - The softirq message processing involved a number of patches changing mutexes to spinlocks and rwlocks, and a fair amount of code re-org in preparation. - Use an rhashtable for rsb structs, rather than our old internal hash table implementation. This also required some re-org of lists and locks preparation for the change. - Drop the dlm_scand kthread, and use timers to clear unused rsb structs. Scanning all rsb's periodically was a lot of wasted work. - Fix recent regression in logic for copying LVB data in user space lock requests" * tag 'dlm-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm: (34 commits) dlm: return -ENOMEM if ls_recover_buf fails dlm: fix sleep in atomic context dlm: use rwlock for lkbidr dlm: use rwlock for rsb hash table dlm: drop dlm_scand kthread and use timers dlm: do not use ref counts for rsb in the toss state dlm: switch to use rhashtable for rsbs dlm: add rsb lists for iteration dlm: merge toss and keep hash table lists into one list dlm: change to single hashtable lock dlm: increment ls_count for dlm_scand dlm: do message processing in softirq context dlm: use spin_lock_bh for message processing dlm: remove schedule in receive path dlm: convert ls_recv_active from rw_semaphore to rwlock dlm: avoid blocking receive at the end of recovery dlm: convert res_lock to spinlock dlm: convert ls_waiters_mutex to spinlock dlm: drop mutex use in waiters recovery dlm: add new struct to save position in dlm_copy_master_names ...

Pull erofs updates from Gao Xiang: "The LZ4 global buffer count is now configurable instead of the previous per-CPU buffers, which is useful for bare metals with hundreds of CPUs. A reserved buffer pool for LZ4 decompression can also be enabled to minimize the tail allocation latencies under the low memory scenarios with heavy memory pressure. In addition, Zstandard algorithm is now supported as an alternative since it has been requested by users for a while. There are some random cleanups as usual.

Pull gpio updates from Bartosz Golaszewski "This was a quiet release cycle for the GPIO tree and so this pull-request is relatively small. We have one new driver, some minor improvements to the GPIO core code and across several drivers, some DT and documentation updates but in general nothing stands out or is controversial. All changes have spent time in next with no reported issues (or ones that were quickly fixed). GPIO core: - remove more unused legacy interfaces (after converting the last remaining users to better alternatives) - update kerneldocs - improve error handling and log messages in GPIO ACPI code - remove dead code (always true checks) from GPIOLIB New drivers: - add a driver for Intel Granite Rapids-D vGPIO Driver improvements: - use -ENOTSUPP consistently in gpio-regmap and gpio-pcie-idio-24 - provide an ID table for gpio-cros-ec to avoid a driver name fallback check - add support for gpio-ranges for GPIO drivers supporting multiple GPIO banks - switch to using dynamic GPIO base in gpio-brcmstb - fix irq handling in gpio-npcm-sgpio - switch to memory mapped IO accessors in gpio-sch DT bindings: - add support for gpio-ranges to gpio-brcmstb - add support for a new model and the gpio-line-names property to gpio-mpfs Documentation: - replace leading tabs with spaces in code blocks - fix typos" * tag 'gpio-updates-for-v6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (30 commits) gpio: nuvoton: Fix sgpio irq handle error gpiolib: Discourage to use formatting strings in line names gpio: brcmstb: add support for gpio-ranges gpio: of: support gpio-ranges for multiple gpiochip devices dt-bindings: gpio: brcmstb: add gpio-ranges gpio: Add Intel Granite Rapids-D vGPIO driver gpio: brcmstb: Use dynamic GPIO base numbers gpiolib: acpi: Set label for IRQ only lines gpiolib: acpi: Add fwnode name to the GPIO interrupt label gpiolib: Get rid of never false gpio_is_valid() calls gpiolib: acpi: Pass con_id instead of property into acpi_dev_gpio_irq_get_by() gpiolib: acpi: Move acpi_can_fallback_to_crs() out of __acpi_find_gpio() gpiolib: acpi: Simplify error handling in __acpi_find_gpio() gpiolib: acpi: Extract __acpi_find_gpio() helper gpio: sch: Utilise temporary variable for struct device gpio: sch: Switch to memory mapped IO accessors gpio: regmap: Use -ENOTSUPP consistently gpio: pcie-idio-24: Use -ENOTSUPP consistently Documentation: gpio: Replace leading TABs by spaces in code blocks gpiolib: acpi: Check for errors first in acpi_find_gpio() ...

Pull pwm updates from Uwe Kleine-König: "Apart for the normal updates for dt bindings, cleanups and support for new device variants to existing drivers this completes the conversion to pwmchip_alloc() which was started in the v6.9 development cycle. Using pwmchip_alloc() is a precondition to the character device support which allows easier and faster access to PWM devices. However there are some issues I want to clean up before including it in mainline, so this isn't contained here despite it was in next for some time.

Pull regulator updates from Mark Brown: "There's one API update here, a new API factoring out a common pattern for reference voltage supplies. These are supplies used as a reference by analogue circuits where the consumer requests and enables the supply, reads the voltage to calibrate the user and then never touches it again. This is factored out into a single operation which just returns the voltage and uses devm_ to manage the request and enable portion. Otherwise this has been a very quiet release, we've got some new device support, some small fixes, housekeeping and cleanup work but nothing substantial. There's also some non-regulator changes in here, a number of users for the new reference voltage API were merged along with it and some MFD changes were pulled in as dependencies for new driver work.

Pull thermal control updates from Rafael Wysocki: "The most significant part of this is a rework of thermal governors, including a redesign of the thermal governor interface and changes to make some of them take trip point hysteresis into account properly, as well as some related cleanups of the thermal governors and thermal core. The above is based on preliminary changes refactoring thermal data structures and moving the definitions of some of them into the thermal core which also ensure that trip point crossing notifications will be sent to user space via netlink and recorded in the debug statistics in temperature order. In addition, netlink bind/unbind notifications are added to the thermal core and the Intel HFI driver is modified to use them to avoid sending netlink messages until there are subscribers.

Pull sh updates from John Paul Adrian Glaubitz: "The majority of improvements are coming from Geert Uytterhoeven who took the time to fix a total of 30 cases of "-Wmissing-prototypes" compiler warnings, either by adding a missing header include, defining the missing forward declarations or making the functions in question static. In the case of several DMA functions, the fix was to actually just remove them as they were added but never used. Another one of these warnings was eliminated by removing the left-over sh5 cache handling support, a change that was suggested by Yoshinori Sato and, finally, the last of these warnings was fixed by guarding the function setup_profiling_timer() with CONFIG_PROFILING. While at it, Geert also removed two unneeded casts to kprobe_opcode_t in the kprobes code. Another change was contributed by Guenter Roeck to fix errors that were reported during checksum unit tests. The fix actually reverts the older change cadc4e1a ("sh: Handle calling csum_partial with misaligned data") which turned to be incorrect. It remains to be investigated whether there is a better way to handle misaligned data in csum_partial(). A small fix contributed by Krzysztof Kozlowski drops the incorrect SPI controller spi-max-frequency property in the device tree source file for the J2 device platform while Uwe Kleine-König converted the push-switch driver to have its callback function return void, a change that is currently being applied to all drivers throughout the kernel in order to avoid resource leaks.

Pull x86 interrupt handling updates from Thomas Gleixner: "Add support for posted interrupts on bare metal. Posted interrupts is a virtualization feature which allows to inject interrupts directly into a guest without host interaction. The VT-d interrupt remapping hardware sets the bit which corresponds to the interrupt vector in a vector bitmap which is either used to inject the interrupt directly into the guest via a virtualized APIC or in case that the guest is scheduled out provides a host side notification interrupt which informs the host that an interrupt has been marked pending in the bitmap. This can be utilized on bare metal for scenarios where multiple devices, e.g. NVME storage, raise interrupts with a high frequency. In the default mode these interrupts are handles independently and therefore require a full roundtrip of interrupt entry/exit. Utilizing posted interrupts this roundtrip overhead can be avoided by coalescing these interrupt entries to a single entry for the posted interrupt notification. The notification interrupt then demultiplexes the pending bits in a memory based bitmap and invokes the corresponding device specific handlers. Depending on the usage scenario and device utilization throughput improvements between 10% and 130% have been measured. As this is only relevant for high end servers with multiple device queues per CPU attached and counterproductive for situations where interrupts are arriving at distinct times, the functionality is opt-in via a kernel command line parameter" * tag 'x86-irq-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/irq: Use existing helper for pending vector check iommu/vt-d: Enable posted mode for device MSIs iommu/vt-d: Make posted MSI an opt-in command line option x86/irq: Extend checks for pending vectors to posted interrupts x86/irq: Factor out common code for checking pending interrupts x86/irq: Install posted MSI notification handler x86/irq: Factor out handler invocation from common_interrupt() x86/irq: Set up per host CPU posted interrupt descriptors x86/irq: Reserve a per CPU IDT vector for posted MSIs x86/irq: Add a Kconfig option for posted MSI x86/irq: Remove bitfields in posted interrupt descriptor x86/irq: Unionize PID.PIR for 64bit access w/o casting KVM: VMX: Move posted interrupt descriptor out of VMX code

Pull interrupt subsystem updates from Thomas Gleixner: "Core code: - Interrupt storm detection for the lockup watchdog: Lockups which are caused by interrupt storms are not easy to debug because there is no information about the events which make the lockup detector trigger. To make this more user friendly, provide an extenstion to interrupt statistics which allows to take snapshots and an interface to retrieve the delta to the snapshot. Use this new mechanism in the watchdog code to do a two stage lockup analysis by taking the snapshot and printing the deltas for the topmost active interrupts on the second trigger. Note: This contains both the interrupt and the watchdog changes as the latter depend on the former obviously. - Avoid summation loops in the /proc/interrupts output and use the global counter when possible - Skip suspended interrupts on CPU hotplug operations to ensure that they are not delivered before the system resumes the device drivers when coming out of suspend. - On CPU hot-unplug interrupts which are affine to the outgoing CPU are migrated to a different CPU in the affinity mask. This can fail when the CPUs have no vectors left.

Pull x86 timers update from Thomas Gleixner: "A single update for the TSC synchronixation sanity checks: The sad state of TSC being notoriously non-sychronized for several decades caused the kernel to grow quite rigorous sanity checks to detect whether the TSC is valid to be used for timekeeping. The TSC ADJUST MSR provides the offset between the initial TSC value after hardware reset and later modifications. This allows to detect cases where firmware tampers with the TSC and also allows to correct the firmware induced damage by resetting the offset in a controlled way. The universal correct rule is that the TSC ADJUST value has to be consistent within all CPUs of a socket. The kernel further assumes that the TSC offset should be consistent between sockets. That's not really correct as systems with a huge number of sockets are not architecurally guaranteed to reset the per socket TSC base synchronously. In case that the per socket offset is not consistent the kernel resets it to the offset of the boot CPU and then does a synchronization check which corrects for the inter socket delays. That works most of the time, but it is suboptimal as the firmware has eventually better information about the per socket offset and on sane systems that offset should just work in the validation checks" * tag 'x86-timers-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tsc: Trust initial offset in architectural TSC-adjust MSRs
