      io_uring/net: harden multishot termination case for recv · c314094c
      Jens Axboe authored
      If the recv returns zero, or an error, then it doesn't matter if more
      data has already been received for this buffer. A condition like that
      should terminate the multishot receive. Rather than pass in the
      collected return value, pass in whether to terminate or keep the recv
      going separately.
      
      Note that this isn't a bug right now, as the only way to get there is
      via setting MSG_WAITALL with multishot receive. And if an application
      does that, then -EINVAL is returned anyway. But it seems like an easy
      bug to introduce, so let's make it a bit more explicit.

       "Mostly just a set of fixes in here, or little changes that didn't get
        included in the initial pull request. This contains:
      
         - Move the SQPOLL napi polling outside the submission lock (Olivier)
      
         - Rename of the "copy buffers" API that got added in the 6.12 merge
           window. There's really no copying going on, it's just referencing
           the buffers. After a bit of consideration, decided that it was
           better to simply rename this to avoid potential confusion (me)
      
         - Shrink struct io_mapped_ubuf from 48 to 32 bytes, by changing it to
           start + len tracking rather than having start / end in there, and
           by removing the caching of folio_mask when we can just calculate it
           from folio_shift when we need it (me)
      
         - Fixes for the SQPOLL affinity checking (me, Felix)
      
         - Fix for how cqring waiting checks for the presence of task_work.
           Just check it directly rather than check for a specific
           notification mechanism (me)
      
         - Tweak to how request linking is represented in tracing (me)
      
         - Fix a syzbot report that deliberately sets up a huge list of
           overflow entries, and then hits rcu stalls when flushing this list.
           Just check for the need to preempt, and drop/reacquire locks in the
           loop. There's no state maintained over the loop itself, and each
           entry is yanked from head-of-list (me)"

      Linus Torvalds authored
      Pull clk updates from Stephen Boyd:
       "The core clk framework is left largely untouched this time around
        except for support for the newly ratified DT property
        'assigned-clock-rates-u64'.
      
        I'm much more excited about the support for loading DT overlays from
        KUnit tests so that we can test how the clk framework parses DT nodes
        during clk registration. The clk framework has some places that are
        highly DeviceTree dependent so this charts the path to extend the
        KUnit tests to cover even more framework code in the future. I've got
        some more tests on the list that use the DT overlay support, but they
        uncovered issues with clk unregistration that I'm still working on
        fixing.
      
        Outside the core, the clk driver update pile is dominated by Qualcomm
        and Renesas SoCs, making it fairly usual. Looking closer, there are
        fixes for things all over the place, like adding missing clk
        frequencies or moving defines for the number of clks out of DT binding
        headers into the drivers. There are even conversions of DT bindings to
        YAML and migration away from strings to describe clk topology. Overall
        it doesn't look unusual so I expect the new drivers to be where we'll
        have fixes in the coming weeks.
      
        Core:
         - KUnit tests for clk registration and fixed rate basic clk type
         - A couple more devm helpers, one consumer and one provider
         - Support for assigned-clock-rates-u64
      
        New Drivers:
         - Camera, display and GPU clocks on Qualcomm SM4450
         - Camera clocks on Qualcomm SM8150
         - Rockchip rk3576 clks
         - Microchip SAM9X7 clks
         - Renesas RZ/V2H(P) (R9A09G057) clks
      
        Updates:
         - Mark a bunch of struct freq_tbl const to reduce .data usage
         - Add Qualcomm MSM8226 A7PLL and Regera PLL support
         - Fix the Qualcomm Lucid 5LPE PLL configuration sequence to not reuse
           Trion, as they do differ
         - A number of fixes to the Qualcomm SM8550 display clock driver
         - Fold Qualcomm SM8650 display clock driver into SM8550 one
         - Add missing clocks and GDSCs needed for audio on Qualcomm MSM8998
         - Add missing USB MP resets, GPLL9, and QUPv3 DFS to Qualcomm SC8180X
         - Fix sdcc clk frequency tables on Qualcomm SC8180X
         - Drop the Qualcomm SM8150 gcc_cpuss_ahb_clk_src
         - Mark Qualcomm PCIe GDSCs as RET_ON on sm8250 and sm8540 to avoid
           them turning off during suspend
         - Use the HW_CTRL mechanism on Qualcomm SM8550 video clock controller
           GDSCs
         - Get rid of CLK_NR_CLKS defines in Rockchip DT binding headers
         - Some fixes for Rockchip rk3228 and rk3588
         - Exynos850: Add clock for Thermal Management Unit
         - Exynos7885: Fix duplicated ID in the header, add missing TOP PLLs
           and add clocks for USB block in the FSYS clock controller

         - ExynosAutov920: Add new (first) clock controllers: TOP and PERIC0
           (and a bit more complete bindings)

      Pull i2c updates from Wolfram Sang:
       "I2C core:
      
         - finally remove the I2C_COMPAT symbol after 15 years of deprecation
      
         - lock client addresses during initialization to prevent race
           conditions between different kinds of instantiation
      
         - use scoped foreach OF child loops
      
         - testunit cleanups and documentation improvements, as well as two
           new tests, one for repeated start and one for triggering SMBusAlert
           interrupts
      
        I2C host drivers:
      
         - DesignWare and Renesas I2C driver updates.
      
           The first has has undergone through a series of cleanups that have
           been sent to the mailing list a year ago for the first time and
           finally get merged in this pull request. They are many, from typos
           (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline
           functions to librarieas) and many others.
      
         - all the DesignWare Kconfig options have been grouped under the
           I2C_DESIGNWARE_CORE and this required some adaptation in many of
           the kernel configuration files for different arm and mips boards
      
        Cleanups:
      
         - improve the exit path in the runtime resume function for the
           Qualcomm Geni platform
      
         - get rid of the unused "target_addr" parameter in the Intel LJCA
           driver
      
         - intialize the restart_flag in the MediaTek controller in one single
           place
      
         - constify a few global data structures in the virtio driver
      
         - simplify the bus speed handling in the Renesas driver init function
           making it more readable
      
         - improved probe function of the Renesas R-Car driver
      
         - switch the iMX/MXC driver to use RUNTIME_PM_OPS() instead of
           SET_RUNTIME_PM_OPS()
      
         - iMX/MXC driver cleanups
      
         - use devm_clk_get_enabled() to simplify the Renesas EMEV2, Ingenic
           and MPC drivers
      
        Refactoring:
      
         - Fix a potential out of boundary array access in the Nuvoton driver.
      
           This is not a bug fix because the issue could never occur due to
           hardware not having the properties listed in the array. The change
           makes the driver more future proof and, at the same time, silences
           code analyzers.
      
        Improvements:
      
         - several patches improving the runtime power management handling of
           the Renesas I2C (riic) driver
      
         - use a more descriptive adapter name in the Intel i801 driver to
           show the presence of the IDF feature
      
         - kill pending transactions when irq's can't complete their handling
           in the Intel Denverton (ismt) driver, triggering a timeout
      
        New Feature:
      
         - support fast mode plus in the Renesas I2C (riic) driver
      
        New support:
      
         - Added support for:
            - Renesas R9A08G045
            - Rockchip RK3576
            - KEBA I2C
            - Theobroma Systems Mule Multiplexer.
      
         - new i2c-keba.c driver
      
         - new driver for The Mule i2c multiplexer
      
        Core I2C framework:
      
         - move runtime PM functions in order to allow them to be accessed
           during device add
      
        Devicetree:
      
         - nVidia and Qualcomm binding improvements
      
         - get rid of redundant "multi-master" property in the aspeed binding
      
         - convert i2c-sprd binding to YAML

      Pull firewire updates from Takashi Sakamoto:
       "In the FireWire subsystem, tasklets have been used as the bottom half
        of 1394 OHCi hardIRQ. In recent kernel updates, BH workqueues have
        become available, and some developers have proposed replacing the
        tasklet with a BH workqueue.
      
        As a first step towards dropping tasklet use, the 1394 OHCI
        isochronous context can use regular workqueues. In this context, the
        batch of packets is processed in the specific queue, thus the timing
        jitter caused by task scheduling is not so critical.
      
        Additionally, DMA transmission can be scheduled per-packet basis,
        therefore the context can be sleep between the operation of
        transmissions. Furthermore, in-kernel protocol implementation involves
        some CPU-bound tasks, which can sometimes consumes CPU time so long.
        These characteristics suggest that normal workqueues are suitable,
        through BH workqueues are not.
      
        The replacement with a workqueue allows unit drivers to process the
        content of packets in non-atomic context. It brings some reliefs to
        some drivers in sound subsystem that spin-lock is not mandatory
        anymore during isochronous packet processing.
      
        Summary:
      
         - Replace tasklet with workqueue for isochronous context
      
         - Replace IDR with XArray
      
         - Utilize guard macro where possible
      
         - Print deprecation warning when enabling debug parameter of
           firewire-ohci module
      
         - Switch to nonatomic PCM operation"

       "Enumeration:
      
         - Wait for device readiness after reset by polling Vendor ID and
           looking for Configuration RRS instead of polling the Command
           register and looking for non-error completions, to avoid hardware
           retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)
      
         - Rename CRS Completion Status to RRS ('Request Retry Status') to
           match PCIe r6.0 spec usage (Bjorn Helgaas)
      
         - Clear LBMS bit after a manual link retrain so we don't try to
           retrain a link when there's no downstream device anymore (Maciej W.
           Rozycki)
      
         - Revert to the original link speed after retraining fails instead of
           leaving it restricted to 2.5GT/s, so a future device has a chance
           to use higher speeds (Maciej W. Rozycki)
      
         - Wait for each level of downstream bus, not just the first, to
           become accessible before restoring devices on that bus (Ilpo
           Järvinen)
      
         - Add ARCH_PCI_DEV_GROUPS so s390 can add its own attribute_groups
           without having to stomp on the core's pdev->dev.groups (Lukas
           Wunner)
      
        Driver binding:
      
         - Export pcim_request_region(), a managed counterpart of
           pci_request_region(), for use by drivers (Philipp Stanner)
      
         - Export pcim_iomap_region() and deprecate pcim_iomap_regions()
           (Philipp Stanner)
      
         - Request the PCI BAR used by xboxvideo (Philipp Stanner)
      
         - Request and map drm/ast BARs with pcim_iomap_region() (Philipp
           Stanner)
      
        MSI:
      
         - Add MSI_FLAG_NO_AFFINITY flag for devices that mux MSIs onto a
           single IRQ line and cannot set the affinity of each MSI to a
           specific CPU core (Marek Vasut)
      
         - Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
           implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
           mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
           xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'
           warnings (Marek Vasut)
      
        Power management:
      
         - Add pwrctl support for ATH11K inside the WCN6855 package (Konrad
           Dybcio)
      
        PCI device hotplug:

         - Check for PCI_POSSIBLE_ERROR(), not 0xffffffff, in cpqphp
           (weiyufeng)
      
        Virtualization:
      
         - Mark Creative Labs EMU20k2 INTx masking as broken (Alex Williamson)
      
         - Add an ACS quirk for Qualcomm SA8775P, which doesn't advertise ACS
           but does provide ACS-like features (Subramanian Ananthanarayanan)
      
        IOMMU:
      
         - Add function 0 DMA alias quirk for Glenfly Arise audio function,

        NPEM:
      
         - Add Native PCIe Enclosure Management (NPEM) support for sysfs

           is functionally similar to NPEM but mediated by platform firmware
           (Mariusz Tkaczyk)
      
        Device trees:
      
         - Drop minItems and maxItems from ranges in PCI generic host binding
           since host bridges may have several MMIO and I/O port apertures
           (Frank Li)
      
         - Add kirin, rcar-gen2, uniphier DT binding top-level constraints for
           clocks (Krzysztof Kozlowski)
      
        Altera PCIe controller driver:
      
         - Convert altera DT bindings from text to YAML (Matthew Gerlach)
      
         - Replace TLP_REQ_ID() with macro PCI_DEVID(), which does the same
           thing and is what other drivers use (Jinjie Ruan)

         - Use generic PHY APIs to configure mode, speed, and submode, which
           is harmless for devices that implement their own internal PHY
           management and don't set the generic imx_pcie->phy (Frank Li)
      
         - Add i.MX8Q (i.MX8QM, i.MX8QXP, and i.MX8DXL) DT binding and driver

      Linus Torvalds authored
      Pull bcachefs updates from Kent Overstreet:
      
       - rcu_pending, btree key cache rework: this solves lock contenting in
         the key cache, eliminating the biggest source of the srcu lock hold
         time warnings, and drastically improving performance on some metadata
         heavy workloads - on multithreaded creates we're now 3-4x faster than
         xfs.
      
       - We're now using an rhashtable instead of the system inode hash table;
         this is another significant performance improvement on multithreaded
         metadata workloads, eliminating more lock contention.
      
       - for_each_btree_key_in_subvolume_upto(): new helper for iterating over
         keys within a specific subvolume, eliminating a lot of open coded
         "subvolume_get_snapshot()" and also fixing another source of srcu
         lock time warnings, by running each loop iteration in its own
         transaction (as the existing for_each_btree_key() does).
      
       - More work on btree_trans locking asserts; we now assert that we don't
         hold btree node locks when trans->locked is false, which is important
         because we don't use lockdep for tracking individual btree node
         locks.
      
       - Some cleanups and improvements in the bset.c btree node lookup code,
         from Alan.
      
       - Rework of btree node pinning, which we use in backpointers fsck. The
         old hacky implementation, where the shrinker just skipped over nodes
         in the pinned range, was causing OOMs; instead we now use another
         shrinker with a much higher seeks number for pinned nodes.
      
       - Rebalance now uses BCH_WRITE_ONLY_SPECIFIED_DEVS; this fixes an issue
         where rebalance would sometimes fall back to allocating from the full
         filesystem, which is not what we want when it's trying to move data
         to a specific target.
      
       - Use __GFP_ACCOUNT, GFP_RECLAIMABLE for btree node, key cache
         allocations.
      
       - Idmap mounts are now supported (Hongbo Li)
      
       - Rename whiteouts are now supported (Hongbo Li)
      
       - Erasure coding can now handle devices being marked as failed, or
         forcibly removed. We still need the evacuate path for erasure coding,
         but it's getting very close to ready for people to start using.

      sched_ext: Provide a sysfs enable_seq counter · 431844b6
      Andrea Righi authored
      As discussed during the distro-centric session within the sched_ext
      Microconference at LPC 2024, introduce a sequence counter that is
      incremented every time a BPF scheduler is loaded.
      
      This feature can help distributions in diagnosing potential performance
      regressions by identifying systems where users are running (or have ran)
      custom BPF schedulers.
      
      Example:
      
       arighi@virtme-ng~> cat /sys/kernel/sched_ext/enable_seq
       0
       arighi@virtme-ng~> sudo scx_simple
       local=1 global=0
       ^CEXIT: unregistered from user space
       arighi@virtme-ng~> cat /sys/kernel/sched_ext/enable_seq
       1
      
      In this way user-space tools (such as Ubuntu's apport and similar) are
      able to gather and include this information in bug reports.

      mm: fix build on 32-bit targets without MAX_PHYSMEM_BITS · f8eb5bd9
      Linus Torvalds authored
      The merge resolution to deal with the conflict between commits
      ea72ce5d ("x86/kaslr: Expose and use the end of the physical memory
      address space") and 99185c10 ("resource, kunit: add test case for
      region_intersects()") ended up being broken in configurations didn't
      define a MAX_PHYSMEM_BITS and that had a 32-bit 'phys_addr_t'.
      
      The fallback to using all bits set (ie "(-1ULL)") ended up causing a
      build error:
      
          kernel/resource.c: In function ‘gfr_start’:
          include/linux/minmax.h:93:30: error: conversion from ‘long long unsigned int’ to ‘resource_size_t’ {aka ‘unsigned int’} changes value from ‘18446744073709551615’ to ‘4294967295’ [-Werror=overflow]
      
      this was reported by Geert for m68k, but he points out that it happens
      on other 32-bit architectures too, eg mips, xtensa, parisc, and powerpc.
      
      Limiting 'PHYSMEM_END' to a 'phys_addr_t' (which is the same as
      'resource_size_t') fixes the build, but Geert points out that it will
      then cause a silent overflow in mm/sparse.c:
      
      	unsigned long max_sparsemem_pfn = (PHYSMEM_END + 1) >> PAGE_SHIFT;
      
      so we actually do want PHYSMEM_END to be defined a 64-bit type - just
      not all ones, and not larger than 'phys_addr_t'.
      
      The proper fix is probably to not have some kind of default fallback at
      all, but just make sure every architecture has a valid MAX_PHYSMEM_BITS.
      But in the meantime, this just applies the rule that PHYSMEM_END is the
      largest value that fits in a 'phys_addr_t', but does not have the high
      bit set in 64 bits.
      
      Ugly, ugly.
