ACPICA: Refuse to evaluate a method if arguments are missing [+ + +]

    ACPICA: Refuse to evaluate a method if arguments are missing
    
    [ Upstream commit 6fcab2791543924d438e7fa49276d0998b0a069f ]
    
    As reported in [1], a platform firmware update that increased the number
    of method parameters and forgot to update a least one of its callers,
    caused ACPICA to crash due to use-after-free.
    
    Since this a result of a clear AML issue that arguably cannot be fixed
    up by the interpreter (it cannot produce missing data out of thin air),
    address it by making ACPICA refuse to evaluate a method if the caller
    attempts to pass fewer arguments than expected to it.

    ALSA: sb: Don't allow changing the DMA mode during operations
    
    [ Upstream commit ed29e073ba93f2d52832804cabdd831d5d357d33 ]
    
    When a PCM stream is already running, one shouldn't change the DMA
    mode via kcontrol, which may screw up the hardware.  Return -EBUSY
    instead.

    ALSA: sb: Force to disable DMAs once when DMA mode is changed
    
    [ Upstream commit 4c267ae2ef349639b4d9ebf00dd28586a82fdbe6 ]
    
    When the DMA mode is changed on the (still real!) SB AWE32 after
    playing a stream and closing, the previous DMA setup was still
    silently kept, and it can confuse the hardware, resulting in the
    unexpected noises.  As a workaround, enforce the disablement of DMA
    setups when the DMA setup is changed by the kcontrol.

    amd-xgbe: align CL37 AN sequence as per databook
    
    [ Upstream commit 42fd432fe6d320323215ebdf4de4d0d7e56e6792 ]
    
    Update the Clause 37 Auto-Negotiation implementation to properly align
    with the PCS hardware specifications:
    - Fix incorrect bit settings in Link Status and Link Duplex fields
    - Implement missing sequence steps 2 and 7
    
    These changes ensure CL37 auto-negotiation protocol follows the exact
    sequence patterns as specified in the hardware databook.

    amd-xgbe: do not double read link status
    
    [ Upstream commit 16ceda2ef683a50cd0783006c0504e1931cd8879 ]
    
    The link status is latched low so that momentary link drops
    can be detected. Always double-reading the status defeats this
    design feature. Only double read if link was already down
    
    This prevents unnecessary duplicate readings of the link status.

aoe: defer rexmit timer downdev work to workqueue [+ + +]

Date:   Tue Jun 10 17:06:00 2025 +0000

    aoe: defer rexmit timer downdev work to workqueue
    
    [ Upstream commit cffc873d68ab09a0432b8212008c5613f8a70a2c ]
    
    When aoe's rexmit_timer() notices that an aoe target fails to respond to
    commands for more than aoe_deadsecs, it calls aoedev_downdev() which
    cleans the outstanding aoe and block queues. This can involve sleeping,
    such as in blk_mq_freeze_queue(), which should not occur in irq context.
    
    This patch defers that aoedev_downdev() call to the aoe device's
    workqueue.

ata: libata-acpi: Do not assume 40 wire cable if no devices are enabled [+ + +]
Author: Tasos Sahanidis <[email protected]>
Date:   Mon May 19 11:56:55 2025 +0300

    ata: libata-acpi: Do not assume 40 wire cable if no devices are enabled
    
    [ Upstream commit 33877220b8641b4cde474a4229ea92c0e3637883 ]
    
    On at least an ASRock 990FX Extreme 4 with a VIA VT6330, the devices
    have not yet been enabled by the first time ata_acpi_cbl_80wire() is
    called. This means that the ata_for_each_dev loop is never entered,
    and a 40 wire cable is assumed.
    
    The VIA controller on this board does not report the cable in the PCI
    config space, thus having to fall back to ACPI even though no SATA
    bridge is present.
    
    The _GTM values are correctly reported by the firmware through ACPI,
    which has already set up faster transfer modes, but due to the above
    the controller is forced down to a maximum of UDMA/33.
    
    Resolve this by modifying ata_acpi_cbl_80wire() to directly return the
    cable type. First, an unknown cable is assumed which preserves the mode
    set by the firmware, and then on subsequent calls when the devices have
    been enabled, an 80 wire cable is correctly detected.
    
    Since the function now directly returns the cable type, it is renamed
    to ata_acpi_cbl_pata_type().

Bluetooth: hci_core: Fix use-after-free in vhci_flush() [+ + +]
Author: Kuniyuki Iwashima <[email protected]>
Date:   Sun Jul 6 05:34:31 2025 -0400

    Bluetooth: hci_core: Fix use-after-free in vhci_flush()
    
    [ Upstream commit 1d6123102e9fbedc8d25bf4731da6d513173e49e ]
    
    syzbot reported use-after-free in vhci_flush() without repro. [0]
    
    From the splat, a thread close()d a vhci file descriptor while
    its device was being used by iotcl() on another thread.
    
    Once the last fd refcnt is released, vhci_release() calls
    hci_unregister_dev(), hci_free_dev(), and kfree() for struct
    vhci_data, which is set to hci_dev->dev->driver_data.
    
    The problem is that there is no synchronisation after unlinking
    hdev from hci_dev_list in hci_unregister_dev().  There might be
    another thread still accessing the hdev which was fetched before
    the unlink operation.
    
    We can use SRCU for such synchronisation.
    
    Let's run hci_dev_reset() under SRCU and wait for its completion
    in hci_unregister_dev().
    
    Another option would be to restore hci_dev->destruct(), which was
    removed in commit 587ae086f6e4 ("Bluetooth: Remove unused
    hci-destruct cb").  However, this would not be a good solution, as
    we should not run hci_unregister_dev() while there are in-flight
    ioctl() requests, which could lead to another data-race KCSAN splat.
    
    Note that other drivers seem to have the same problem, for exmaple,
    virtbt_remove().

    Bluetooth: hci_sync: revert some mesh modifications
    
    commit 46c0d947b64ac8efcf89dd754213dab5d1bd00aa upstream.
    
    This reverts minor parts of the changes made in commit b338d91703fa
    ("Bluetooth: Implement support for Mesh"). It looks like these changes
    were only made for development purposes but shouldn't have been part of
    the commit.

    Bluetooth: MGMT: mesh_send: check instances prior disabling advertising
    
    commit f3cb5676e5c11c896ba647ee309a993e73531588 upstream.
    
    The unconditional call of hci_disable_advertising_sync() in
    mesh_send_done_sync() also disables other LE advertisings (non mesh
    related).
    
    I am not sure whether this call is required at all, but checking the
    adv_instances list (like done at other places) seems to solve the
    problem.

    Bluetooth: MGMT: set_mesh: update LE scan interval and window
    
    commit e5af67a870f738bb8a4594b6c60c2caf4c87a3c9 upstream.
    
    According to the message of commit b338d91703fa ("Bluetooth: Implement
    support for Mesh"), MGMT_OP_SET_MESH_RECEIVER should set the passive scan
    parameters.  Currently the scan interval and window parameters are
    silently ignored, although user space (bluetooth-meshd) expects that
    they can be used [1]

    Bluetooth: Prevent unintended pause by checking if advertising is active
    
    [ Upstream commit 1f029b4e30a602db33dedee5ac676e9236ad193c ]
    
    When PA Create Sync is enabled, advertising resumes unexpectedly.
    Therefore, it's necessary to check whether advertising is currently
    active before attempting to pause it.

    From the crash dump, we found that the cpu_map_flush_list inside
    redirect info is partially corrupted: its list_head->next points to
    itself, but list_head->prev points to a valid list of unflushed bq
    entries.
    
    This turned out to be a result of missed XDP flush on redirect lists. By
    digging in the actual source code, we found that
    commit 7f0a168b0441 ("bnxt_en: Add completion ring pointer in TX and RX
    ring structures") incorrectly overwrites the event mask for XDP_REDIRECT
    in bnxt_rx_xdp. We can stably reproduce this crash by returning XDP_TX
    and XDP_REDIRECT randomly for incoming packets in a naive XDP program.
    Properly propagate the XDP_REDIRECT events back fixes the crash.

    btrfs: fix iteration of extrefs during log replay
    
    [ Upstream commit 54a7081ed168b72a8a2d6ef4ba3a1259705a2926 ]
    
    At __inode_add_ref() when processing extrefs, if we jump into the next
    label we have an undefined value of victim_name.len, since we haven't
    initialized it before we did the goto. This results in an invalid memory
    access in the next iteration of the loop since victim_name.len was not
    initialized to the length of the name of the current extref.
    
    Fix this by initializing victim_name.len with the current extref's name
    length.

    During log replay, at __add_inode_ref(), when we are searching for inode
    ref keys we totally ignore if btrfs_search_slot() returns an error. This
    may make a log replay succeed when there was an actual error and leave
    some metadata inconsistency in a subvolume tree. Fix this by checking if
    an error was returned from btrfs_search_slot() and if so, return it to
    the caller.

    btrfs: fix qgroup reservation leak on failure to allocate ordered extent
    
    [ Upstream commit 1f2889f5594a2bc4c6a52634c4a51b93e785def5 ]
    
    If we fail to allocate an ordered extent for a COW write we end up leaking
    a qgroup data reservation since we called btrfs_qgroup_release_data() but
    we didn't call btrfs_qgroup_free_refroot() (which would happen when
    running the respective data delayed ref created by ordered extent
    completion or when finishing the ordered extent in case an error happened).
    
    So make sure we call btrfs_qgroup_free_refroot() if we fail to allocate an
    ordered extent for a COW write.

    btrfs: propagate last_unlink_trans earlier when doing a rmdir
    
    [ Upstream commit c466e33e729a0ee017d10d919cba18f503853c60 ]
    
    In case the removed directory had a snapshot that was deleted, we are
    propagating its inode's last_unlink_trans to the parent directory after
    we removed the entry from the parent directory. This leaves a small race
    window where someone can log the parent directory after we removed the
    entry and before we updated last_unlink_trans, and as a result if we ever
    try to replay such a log tree, we will fail since we will attempt to
    remove a snapshot during log replay, which is currently not possible and
    results in the log replay (and mount) to fail. This is the type of failure
    described in commit 1ec9a1ae1e30 ("Btrfs: fix unreplayable log after
    snapshot delete + parent dir fsync").
    
    So fix this by propagating the last_unlink_trans to the parent directory
    before we remove the entry from it.

btrfs: use btrfs_record_snapshot_destroy() during rmdir [+ + +]

    btrfs: use btrfs_record_snapshot_destroy() during rmdir
    
    [ Upstream commit 157501b0469969fc1ba53add5049575aadd79d80 ]
    
    We are setting the parent directory's last_unlink_trans directly which
    may result in a concurrent task starting to log the directory not see the
    update and therefore can log the directory after we removed a child
    directory which had a snapshot within instead of falling back to a
    transaction commit. Replaying such a log tree would result in a mount
    failure since we can't currently delete snapshots (and subvolumes) during
    log replay. This is the type of failure described in commit 1ec9a1ae1e30
    ("Btrfs: fix unreplayable log after snapshot delete + parent dir fsync").
    
    Fix this by using btrfs_record_snapshot_destroy() which updates the
    last_unlink_trans field while holding the inode's log_mutex lock.

dma-buf: fix timeout handling in dma_resv_wait_timeout v2 [+ + +]

    dma-buf: fix timeout handling in dma_resv_wait_timeout v2
    
    commit 2b95a7db6e0f75587bffddbb490399cbb87e4985 upstream.
    
    Even the kerneldoc says that with a zero timeout the function should not
    wait for anything, but still return 1 to indicate that the fences are
    signaled now.
    
    Unfortunately that isn't what was implemented, instead of only returning
    1 we also waited for at least one jiffies.
    
    Fix that by adjusting the handling to what the function is actually
    documented to do.

drm/exynos: fimd: Guard display clock control with runtime PM calls [+ + +]

    drm/exynos: fimd: Guard display clock control with runtime PM calls
    
    [ Upstream commit 5d91394f236167ac624b823820faf4aa928b889e ]
    
    Commit c9b1150a68d9 ("drm/atomic-helper: Re-order bridge chain pre-enable
    and post-disable") changed the call sequence to the CRTC enable/disable
    and bridge pre_enable/post_disable methods, so those bridge methods are
    now called when CRTC is not yet enabled.
    
    This causes a lockup observed on Samsung Peach-Pit/Pi Chromebooks. The
    source of this lockup is a call to fimd_dp_clock_enable() function, when
    FIMD device is not yet runtime resumed. It worked before the mentioned
    commit only because the CRTC implemented by the FIMD driver was always
    enabled what guaranteed the FIMD device to be runtime resumed.
    
    This patch adds runtime PM guards to the fimd_dp_clock_enable() function
    to enable its proper operation also when the CRTC implemented by FIMD is
    not yet enabled.

    drm/i915/dp_mst: Work around Thunderbolt sink disconnect after SINK_COUNT_ESI read
    
    [ Upstream commit 9cb15478916e849d62a6ec44b10c593b9663328c ]
    
    Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT
    link may get disconnected inadvertently if the SINK_COUNT_ESI and the
    DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX
    transaction. Work around the issue by reading these registers in
    separate transactions.
    
    The issue affects MTL+ platforms and will be fixed in the DP-in adapter
    firmware, however releasing that firmware fix may take some time and is
    not guaranteed to be available for all systems. Based on this apply the
    workaround on affected platforms.

drm/i915/gsc: mei interrupt top half should be in irq disabled context [+ + +]

    drm/i915/gsc: mei interrupt top half should be in irq disabled context
    
    [ Upstream commit 8cadce97bf264ed478669c6f32d5603b34608335 ]
    
    MEI GSC interrupt comes from i915. It has top half and bottom half.
    Top half is called from i915 interrupt handler. It should be in
    irq disabled context.
    
    With RT kernel, by default i915 IRQ handler is in threaded IRQ. MEI GSC
    top half might be in threaded IRQ context. generic_handle_irq_safe API
    could be called from either IRQ or process context, it disables local
    IRQ then calls MEI GSC interrupt top half.
    
    This change fixes A380/A770 GPU boot hang issue with RT kernel.

    Closer analysis of CI results history has revealed a dependency of the
    error on a few IGT tests, namely:
    - igt@api_intel_allocator@fork-simple-stress-signal,
    - igt@api_intel_allocator@two-level-inception-interruptible,
    - igt@gem_linear_blits@interruptible,
    - igt@prime_mmap_coherency@ioctl-errors,
    which invisibly trigger the issue, then exhibited with first driver unbind
    attempt.
    
    All of the above tests perform actions which are actively interrupted with
    signals.  Further debugging has allowed to narrow that scope down to
    DRM_IOCTL_I915_GEM_EXECBUFFER2, and ring_context_alloc(), specific to ring
    submission, in particular.
    
    If successful then that function, or its execlists or GuC submission
    equivalent, is supposed to be called only once per GEM context engine,
    followed by raise of a flag that prevents the function from being called
    again.  The function is expected to unwind its internal errors itself, so
    it may be safely called once more after it returns an error.
    
    In case of ring submission, the function first gets a reference to the
    engine's legacy timeline and then allocates a VMA.  If the VMA allocation
    fails, e.g. when i915_vma_instance() called from inside is interrupted
    with a signal, then ring_context_alloc() fails, leaving the timeline held
    referenced.  On next I915_GEM_EXECBUFFER2 IOCTL, another reference to the
    timeline is got, and only that last one is put on successful completion.
    As a consequence, the legacy timeline, with its underlying engine status
    page's VMA object, is still held and not released on driver unbind.
    
    Get the legacy timeline only after successful allocation of the context
    engine's VMA.
    
    v2: Add a note on other submission methods (Krzysztof Karas):
        Both execlists and GuC submission use lrc_alloc() which seems free
        from a similar issue.

drm/i915/selftests: Change mock_request() to return error pointers [+ + +]

    drm/i915/selftests: Change mock_request() to return error pointers
    
    [ Upstream commit caa7c7a76b78ce41d347003f84975125383e6b59 ]
    
    There was an error pointer vs NULL bug in __igt_breadcrumbs_smoketest().
    The __mock_request_alloc() function implements the
    smoketest->request_alloc() function pointer.  It was supposed to return
    error pointers, but it propogates the NULL return from mock_request()
    so in the event of a failure, it would lead to a NULL pointer
    dereference.
    
    To fix this, change the mock_request() function to return error pointers
    and update all the callers to expect that.

    The comparison in enic_change_mtu() incorrectly used the current
    netdev->mtu instead of the new new_mtu value when warning about
    an MTU exceeding the port MTU. This could suppress valid warnings

    ethernet: atl1: Add missing DMA mapping error checks and count errors
    
    [ Upstream commit d72411d20905180cdc452c553be17481b24463d2 ]
    
    The `dma_map_XXX()` functions can fail and must be checked using
    `dma_mapping_error()`.  This patch adds proper error handling for all
    DMA mapping calls.
    
    In `atl1_alloc_rx_buffers()`, if DMA mapping fails, the buffer is
    deallocated and marked accordingly.
    
    In `atl1_tx_map()`, previously mapped buffers are unmapped and the
    packet is dropped on failure.
    
    If `atl1_xmit_frame()` drops the packet, increment the tx_error counter.

    The root cause is user can update post-eof page via mmap [1], however, f2fs
    missed to zero post-eof page in below operations, so, once it expands i_size,
    then it will include dummy data locates previous post-eof page, so during
    below operations, we need to zero post-eof page.
    
    Operations which can include dummy data after previous i_size after expanding
    i_size:
    - write
    - mapwrite [1]
    - truncate
    - fallocate
     * preallocate
     * zero_range
     * insert_range
     * collapse_range
    - clone_range (doesn’t support in f2fs)

    fs: export anon_inode_make_secure_inode() and fix secretmem LSM bypass
    
    [ Upstream commit cbe4134ea4bc493239786220bd69cb8a13493190 ]
    
    Export anon_inode_make_secure_inode() to allow KVM guest_memfd to create
    anonymous inodes with proper security context. This replaces the current
    pattern of calling alloc_anon_inode() followed by
    inode_init_security_anon() for creating security context manually.
    
    This change also fixes a security regression in secretmem where the
    S_PRIVATE flag was not cleared after alloc_anon_inode(), causing
    LSM/SELinux checks to be bypassed for secretmem file descriptors.
    
    As guest_memfd currently resides in the KVM module, we need to export this
    symbol for use outside the core kernel. In the future, guest_memfd might be
    moved to core-mm, at which point the symbols no longer would have to be
    exported. When/if that happens is still unclear.

    amd_i2c_dw_xfer_quirk() inits msgs and msgs_num, but not msg_write_idx.

    [ Upstream commit 0325143b59c6c6d79987afc57d2456e7a20d13b7 ]
    
    I226 devices advertise support for the PCI-E link L1.2 substate. However,
    due to a hardware limitation, the exit latency from this low-power state
    is longer than the packet buffer can tolerate under high traffic
    conditions. This can lead to packet loss and degraded performance.
    
    To mitigate this, disable the L1.2 substate. The increased power draw
    between L1.1 and L1.2 is insignificant.

    iommu/rockchip: prevent iommus dead loop when two masters share one IOMMU
    
    commit 62e062a29ad5133f67c20b333ba0a952a99161ae upstream.
    
    When two masters share an IOMMU, calling ops->of_xlate during
    the second master's driver init may overwrite iommu->domain set
    by the first. This causes the check if (iommu->domain == domain)
    in rk_iommu_attach_device() to fail, resulting in the same
    iommu->node being added twice to &rk_domain->iommus, which can
    lead to an infinite loop in subsequent &rk_domain->iommus operations.

    lib: test_objagg: Set error message in check_expect_hints_stats()
    
    [ Upstream commit e6ed134a4ef592fe1fd0cafac9683813b3c8f3e8 ]
    
    Smatch complains that the error message isn't set in the caller:

        error: uninitialized symbol 'errmsg'.
    
    This static checker warning only showed up after a recent refactoring
    but the bug dates back to when the code was originally added.  This
    likely doesn't affect anything in real life.

    commit 009c3a4bc41e855fd76f92727f9fbae4e5917d7f upstream.
    
    Move the BROKEN_SD_DISCARD quirk for certain SanDisk SD cards from the
    `mmc_blk_fixups[]` to `mmc_sd_fixups[]`. This ensures the quirk is
    applied earlier in the device initialization process, aligning with the
    reasoning in [1]. Applying the quirk sooner prevents the kernel from
    incorrectly enabling discard support on affected cards during initial
    setup.

mtk-sd: Fix a pagefault in dma_unmap_sg() for not prepared data [+ + +]

    mtk-sd: Fix a pagefault in dma_unmap_sg() for not prepared data
    
    commit 539d80575b810c7a5987c7ac8915e3bc99c03695 upstream.
    
    When swiotlb buffer is full, the dma_map_sg() returns 0 to
    msdc_prepare_data(), but it does not check it and sets the
    MSDC_PREPARE_FLAG.
    
    swiotlb_tbl_map_single() /* prints "swiotlb buffer is full" */
      <-swiotlb_map()
        <-dma_direct_map_page()
          <-dma_direct_map_sg()
            <-__dma_map_sg_attrs()
              <-dma_map_sg_attrs()
                <-dma_map_sg()  /* returns 0 (pages mapped) */
                  <-msdc_prepare_data()
    
    Then, the msdc_unprepare_data() checks MSDC_PREPARE_FLAG and calls
    dma_unmap_sg() with unmapped pages. It causes a page fault.
    
    To fix this problem, Do not set MSDC_PREPARE_FLAG if dma_map_sg()
    fails because this is not prepared.

    commit f5de469990f19569627ea0dd56536ff5a13beaa3 upstream.
    
    If msdc_prepare_data() fails to map the DMA region, the request is
    not prepared for data receiving, but msdc_start_data() proceeds
    the DMA with previous setting.
    Since this will lead a memory corruption, we have to stop the
    request operation soon after the msdc_prepare_data() fails to
    prepare it.

net/sched: Always pass notifications when child class becomes empty [+ + +]
Author: Lion Ackermann <[email protected]>
Date:   Mon Jun 30 15:27:30 2025 +0200

    net/sched: Always pass notifications when child class becomes empty
    
    [ Upstream commit 103406b38c600fec1fe375a77b27d87e314aea09 ]
    
    Certain classful qdiscs may invoke their classes' dequeue handler on an
    enqueue operation. This may unexpectedly empty the child qdisc and thus
    make an in-flight class passive via qlen_notify(). Most qdiscs do not
    expect such behaviour at this point in time and may re-activate the
    class eventually anyways which will lead to a use-after-free.
    
    The referenced fix commit attempted to fix this behavior for the HFSC
    case by moving the backlog accounting around, though this turned out to
    be incomplete since the parent's parent may run into the issue too.
    The following reproducer demonstrates this use-after-free:
    
        tc qdisc add dev lo root handle 1: drr
        tc filter add dev lo parent 1: basic classid 1:1
        tc class add dev lo parent 1: classid 1:1 drr
        tc qdisc add dev lo parent 1:1 handle 2: hfsc def 1
        tc class add dev lo parent 2: classid 2:1 hfsc rt m1 8 d 1 m2 0
        tc qdisc add dev lo parent 2:1 handle 3: netem
        tc qdisc add dev lo parent 3:1 handle 4: blackhole
    
        echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888
        tc class delete dev lo classid 1:1
        echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888
    
    Since backlog accounting issues leading to a use-after-frees on stale
    class pointers is a recurring pattern at this point, this patch takes
    a different approach. Instead of trying to fix the accounting, the patch
    ensures that qdisc_tree_reduce_backlog always calls qlen_notify when
    the child qdisc is empty. This solves the problem because deletion of
    qdiscs always involves a call to qdisc_reset() and / or
    qdisc_purge_queue() which ultimately resets its qlen to 0 thus causing
    the following qdisc_tree_reduce_backlog() to report to the parent. Note
    that this may call qlen_notify on passive classes multiple times. This
    is not a problem after the recent patch series that made all the
    classful qdiscs qlen_notify() handlers idempotent.

net: usb: lan78xx: fix WARN in __netif_napi_del_locked on disconnect [+ + +]

    net: usb: lan78xx: fix WARN in __netif_napi_del_locked on disconnect
    
    [ Upstream commit 6c7ffc9af7186ed79403a3ffee9a1e5199fc7450 ]
    
    Remove redundant netif_napi_del() call from disconnect path.
    
    A WARN may be triggered in __netif_napi_del_locked() during USB device
    disconnect:
    
      WARNING: CPU: 0 PID: 11 at net/core/dev.c:7417 __netif_napi_del_locked+0x2b4/0x350
    
    This happens because netif_napi_del() is called in the disconnect path while
    NAPI is still enabled. However, it is not necessary to call netif_napi_del()
    explicitly, since unregister_netdev() will handle NAPI teardown automatically
    and safely. Removing the redundant call avoids triggering the warning.

    nfs: Clean up /proc/net/rpc/nfs when nfs_fs_proc_net_init() fails.
    
    [ Upstream commit e8d6f3ab59468e230f3253efe5cb63efa35289f7 ]
    
    syzbot reported a warning below [1] following a fault injection in
    nfs_fs_proc_net_init(). [0]
    
    When nfs_fs_proc_net_init() fails, /proc/net/rpc/nfs is not removed.
    
    Later, rpc_proc_exit() tries to remove /proc/net/rpc, and the warning
    is logged as the directory is not empty.
    
    Let's handle the error of nfs_fs_proc_net_init() properly.

NFSv4/flexfiles: Fix handling of NFS level errors in I/O [+ + +]
Author: Trond Myklebust <[email protected]>
Date:   Thu Jun 19 15:16:11 2025 -0400

    NFSv4/flexfiles: Fix handling of NFS level errors in I/O
    
    [ Upstream commit 38074de35b015df5623f524d6f2b49a0cd395c40 ]
    
    Allow the flexfiles error handling to recognise NFS level errors (as
    opposed to RPC level errors) and handle them separately. The main
    motivator is the NFSERR_PERM errors that get returned if the NFS client
    connects to the data server through a port number that is lower than
    1024. In that case, the client should disconnect and retry a READ on a
    different data server, or it should retry a WRITE after reconnecting.

NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN [+ + +]

    NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN
    
    [ Upstream commit c01776287414ca43412d1319d2877cbad65444ac ]
    
    We found a few different systems hung up in writeback waiting on the same
    page lock, and one task waiting on the NFS_LAYOUT_DRAIN bit in
    pnfs_update_layout(), however the pnfs_layout_hdr's plh_outstanding count
    was zero.
    
    It seems most likely that this is another race between the waiter and waker
    similar to commit ed0172af5d6f ("SUNRPC: Fix a race to wake a sync task").
    Fix it up by applying the advised barrier.

    [ Upstream commit 561aa0e22b70a5e7246b73d62a824b3aef3fc375 ]
    
    dma_map_XXX() functions return values DMA_MAPPING_ERROR as error values
    which is often ~0.  The error value should be tested with
    dma_mapping_error().
    
    This patch creates a new function in niu_ops to test if the mapping
    failed.  The test is fixed in niu_rbr_add_page(), added in
    niu_start_xmit() and the successfully mapped pages are unmaped upon error.

    platform/mellanox: mlxreg-lc: Fix logic error in power state check
    
    [ Upstream commit 644bec18e705ca41d444053407419a21832fcb2f ]
    
    Fixes a logic issue in mlxreg_lc_completion_notify() where the
    intention was to check if MLXREG_LC_POWERED flag is not set before
    powering on the device.
    
    The original code used "state & ~MLXREG_LC_POWERED" to check for the
    absence of the POWERED bit. However this condition evaluates to true
    even when other bits are set, leading to potentially incorrect
    behavior.
    
    Corrected the logic to explicitly check for the absence of
    MLXREG_LC_POWERED using !(state & MLXREG_LC_POWERED).

    [ Upstream commit d03cfde56f5cf9ec50b4cf099a42bf056fc80ddd ]
    
    The module core already guarantees that a module can only be unloaded

    firmware_attributes_class to clean up their devices before unloading,
    the lifetime of the firmware_attributes_class can be bound to the
    lifetime of the module.
    This enables the direct usage of firmware_attributes_class from the
    drivers, without having to go through the lifecycle functions,
    leading to simplifications for both the subsystem and its users.

    Since commit 43a7206b0963 ("driver core: class: make class_register() take
    a const *"), the driver core allows for struct class to be in read-only
    memory, so move the fw_attr_class structure to be declared at build time
    placing it into read-only memory, instead of having to be dynamically
    allocated at boot time.

powercap: intel_rapl: Do not change CLAMPING bit if ENABLE bit cannot be changed [+ + +]

    powercap: intel_rapl: Do not change CLAMPING bit if ENABLE bit cannot be changed
    
    commit 964209202ebe1569c858337441e87ef0f9d71416 upstream.
    
    PL1 cannot be disabled on some platforms. The ENABLE bit is still set
    after software clears it. This behavior leads to a scenario where, upon
    user request to disable the Power Limit through the powercap sysfs, the
    ENABLE bit remains set while the CLAMPING bit is inadvertently cleared.
    
    According to the Intel Software Developer's Manual, the CLAMPING bit,
    "When set, allows the processor to go below the OS requested P states in
    order to maintain the power below specified Platform Power Limit value."
    
    Thus this means the system may operate at higher power levels than
    intended on such platforms.
    
    Enhance the code to check ENABLE bit after writing to it, and stop
    further processing if ENABLE bit cannot be changed.

    powerpc/kernel: Fix ppc_save_regs inclusion in build
    
    commit 93bd4a80efeb521314485a06d8c21157240497bb upstream.
    
    Recent patch fixed an old commit
    'fc2a5a6161a2 ("powerpc/64s: ppc_save_regs is now needed for all 64s builds")'
    which is to include building of ppc_save_reg.c only when XMON
    and KEXEC_CORE and PPC_BOOK3S are enabled. This was valid, since
    ppc_save_regs was called only in replay_system_reset() of old
    irq.c which was under BOOK3S.
    
    But there has been multiple refactoring of irq.c and have
    added call to ppc_save_regs() from __replay_soft_interrupts
    -> replay_soft_interrupts which is part of irq_64.c included
    under CONFIG_PPC64. And since ppc_save_regs is called in
    CRASH_DUMP path as part of crash_setup_regs in kexec.h,
    CONFIG_PPC32 also needs it.
    
    So with this recent patch which enabled the building of
    ppc_save_regs.c caused a build break when none of these
    (XMON, KEXEC_CORE, BOOK3S) where enabled as part of config.
    Patch to enable building of ppc_save_regs.c by defaults.

    powerpc: Fix struct termio related ioctl macros
    
    [ Upstream commit ab107276607af90b13a5994997e19b7b9731e251 ]
    
    Since termio interface is now obsolete, include/uapi/asm/ioctls.h
    has some constant macros referring to "struct termio", this caused
    build failure at userspace.
    
    In file included from /usr/include/asm/ioctl.h:12,
                     from /usr/include/asm/ioctls.h:5,
                     from tst-ioctls.c:3:
    tst-ioctls.c: In function 'get_TCGETA':
    tst-ioctls.c:12:10: error: invalid application of 'sizeof' to incomplete type 'struct termio'
       12 |   return TCGETA;
          |          ^~~~~~
    
    Even though termios.h provides "struct termio", trying to juggle definitions around to
    make it compile could introduce regressions. So better to open code it.

    Currently the call_rcu() API does not check whether a callback
    pointer is NULL. If NULL is passed, rcu_core() will try to invoke
    it, resulting in NULL pointer dereference and a kernel crash.

    for NULL and emits a kernel stack trace to help identify a faulty

    [ Upstream commit 3cc1dbfddf88dc5ecce0a75185061403b1f7352d ]
    
    To get the device HW counters, a non-representor switchdev device
    should use the mlx5_ib_query_q_counters() function and query all of
    the available counters. While a representor device in switchdev mode
    should use the mlx5_ib_query_q_counters_vport() function and query only
    the Q_Counters without the PPCNT counters and congestion control counters,
    since they aren't relevant for a representor device.
    
    Currently a non-representor switchdev device skips querying the PPCNT
    counters and congestion control counters, leaving them unupdated.
    Fix that by properly querying those counters for non-representor devices.

regulator: fan53555: add enable_time support and soft-start times [+ + +]
Author: Heiko Stuebner <[email protected]>
Date:   Fri Jun 6 21:04:18 2025 +0200

    regulator: fan53555: add enable_time support and soft-start times
    
    [ Upstream commit 8acfb165a492251a08a22a4fa6497a131e8c2609 ]
    
    The datasheets for all the fan53555 variants (and clones using the same
    interface) define so called soft start times, from enabling the regulator
    until at least some percentage of the output (i.e. 92% for the rk860x
    types) are available.
    
    The regulator framework supports this with the enable_time property
    but currently the fan53555 driver does not define enable_times for any
    variant.
    
    I ran into a problem with this while testing the new driver for the
    Rockchip NPUs (rocket), which does runtime-pm including disabling and
    enabling a rk8602 as needed. When reenabling the regulator while running
    a load, fatal hangs could be observed while enabling the associated
    power-domain, which the regulator supplies.
    
    Experimentally setting the regulator to always-on, made the issue
    disappear, leading to the missing delay to let power stabilize.
    And as expected, setting the enable-time to a non-zero value
    according to the datasheet also resolved the regulator-issue.
    
    The datasheets in nearly all cases only specify "typical" values,
    except for the fan53555 type 08. There both a typical and maximum
    value are listed - 40uS apart.
    
    For all typical values I've added 100uS to be on the safe side.
    Individual details for the relevant regulators below:
    
    - fan53526:
      The datasheet for all variants lists a typical value of 150uS, so
      make that 250uS with safety margin.
    - fan53555:
      types 08 and 18 (unsupported) are given a typical enable time of 135uS
      but also a maximum of 175uS so use that value. All the other types only
      have a typical time in the datasheet of 300uS, so give a bit margin by
      setting it to 400uS.
    - rk8600 + rk8602:
      Datasheet reports a typical value of 260us, so use 360uS to be safe.
    - syr82x + syr83x:
      All datasheets report typical soft-start values of 300uS for these
      regulators, so use 400uS.
    - tcs452x:
      Datasheet sadly does not report a soft-start time, so I've not set
      an enable-time

regulator: gpio: Fix the out-of-bounds access to drvdata::gpiods [+ + +]

    regulator: gpio: Fix the out-of-bounds access to drvdata::gpiods
    
    commit c9764fd88bc744592b0604ccb6b6fc1a5f76b4e3 upstream.
    
    drvdata::gpiods is supposed to hold an array of 'gpio_desc' pointers. But
    the memory is allocated for only one pointer. This will lead to
    out-of-bounds access later in the code if 'config::ngpios' is > 1. So
    fix the code to allocate enough memory to hold 'config::ngpios' of GPIO
    descriptors.
    
    While at it, also move the check for memory allocation failure to be below
    the allocation to make it more readable.

    The IS_DGFX check was put in place because error capture of buffer
    objects is expected to be broken on devices with VRAM.
    
    Userspace fix[1] to the impacted media driver has been submitted, merged
    and a new driver release is out as 25.2.3 where the capture flag is
    dropped on DG1 thus unblocking the usage of media driver on DG1.

rose: fix dangling neighbour pointers in rose_rt_device_down() [+ + +]
Author: Kohei Enju <[email protected]>
Date:   Sun Jun 29 12:06:31 2025 +0900

    rose: fix dangling neighbour pointers in rose_rt_device_down()
    
    [ Upstream commit 34a500caf48c47d5171f4aa1f237da39b07c6157 ]
    
    There are two bugs in rose_rt_device_down() that can cause
    use-after-free:
    
    1. The loop bound `t->count` is modified within the loop, which can
       cause the loop to terminate early and miss some entries.
    
    2. When removing an entry from the neighbour array, the subsequent entries
       are moved up to fill the gap, but the loop index `i` is still
       incremented, causing the next entry to be skipped.
    
    For example, if a node has three neighbours (A, A, B) with count=3 and A
    is being removed, the second A is not checked.
    
        i=0: (A, A, B) -> (A, B) with count=2
              ^ checked
        i=1: (A, B)    -> (A, B) with count=2
                 ^ checked (B, not A!)
        i=2: (doesn't occur because i < count is false)
    
    This leaves the second A in the array with count=2, but the rose_neigh
    structure has been freed. Code that accesses these entries assumes that
    the first `count` entries are valid pointers, causing a use-after-free
    when it accesses the dangling pointer.
    
    Fix both issues by iterating over the array in reverse order with a fixed
    loop bound. This ensures that all entries are examined and that the removal
    of an entry doesn't affect subsequent iterations.

rtc: cmos: use spin_lock_irqsave in cmos_interrupt [+ + +]
Author: Mateusz Jończyk <[email protected]>
Date:   Sat Jun 7 23:06:08 2025 +0200

    rtc: cmos: use spin_lock_irqsave in cmos_interrupt
    
    commit 00a39d8652ff9088de07a6fe6e9e1893452fe0dd upstream.
    
    cmos_interrupt() can be called in a non-interrupt context, such as in
    an ACPI event handler (which runs in an interrupt thread). Therefore,
    usage of spin_lock(&rtc_lock) is insecure. Use spin_lock_irqsave() /
    spin_unlock_irqrestore() instead.
    
    Before a misguided
    commit 6950d046eb6e ("rtc: cmos: Replace spin_lock_irqsave with spin_lock in hard IRQ")
    the cmos_interrupt() function used spin_lock_irqsave(). That commit
    changed it to spin_lock() and broke locking, which was partially fixed in
    commit 13be2efc390a ("rtc: cmos: Disable irq around direct invocation of cmos_interrupt()")
    
    That second commit did not take account of the ACPI fixed event handler
    pathway, however. It introduced local_irq_disable() workarounds in
    cmos_check_wkalrm(), which can cause problems on PREEMPT_RT kernels
    and are now unnecessary.
    
    Add an explicit comment so that this change will not be reverted by
    mistake.

    scsi: ufs: core: Add OPP support for scaling clocks and regulators
    
    [ Upstream commit 930bd77ebe3dc23b18aa49e55e6a515d5663d67a ]
    
    UFS core is only scaling the clocks during devfreq scaling and
    initialization. But for an optimum power saving, regulators should also be
    scaled along with the clocks.
    
    So let's use the OPP framework which supports scaling clocks, regulators,
    and performance state using OPP table defined in devicetree. For
    accomodating the OPP support, the existing APIs (ufshcd_scale_clks,
    ufshcd_is_devfreq_scaling_required and ufshcd_devfreq_scale) are modified
    to accept "freq" as an argument which in turn used by the OPP helpers.
    
    The OPP support is added along with the old freq-table based clock scaling
    so that the existing platforms work as expected.

    coming, ufshcd_clk_scaling_start_busy (thread B) may get host_lock after
    thread A first time release host_lock. Then thread A second time get
    host_lock will set clk_scaling.window_start_t = 0 which scale up clock
    abnormal next polling_ms time.  Also inlines another

    Below is racing step:

smb: client: fix race condition in negotiate timeout by using more precise timing [+ + +]

Date:   Thu Jul 3 21:29:52 2025 +0800

    smb: client: fix race condition in negotiate timeout by using more precise timing
    
    [ Upstream commit 266b5d02e14f3a0e07414e11f239397de0577a1d ]
    
    When the SMB server reboots and the client immediately accesses the mount
    point, a race condition can occur that causes operations to fail with
    "Host is down" error.
    
    Reproduction steps:
      # Mount SMB share
      mount -t cifs //192.168.245.109/TEST /mnt/ -o xxxx
      ls /mnt
    
      # Reboot server
      ssh [email protected] reboot
      ssh [email protected] /path/to/cifs_server_setup.sh
      ssh [email protected] systemctl stop firewalld
    
      # Immediate access fails
      ls /mnt
      ls: cannot access '/mnt': Host is down
    
      # But works if there is a delay
    
    The issue is caused by a race condition between negotiate and reconnect.
    The 20-second negotiate timeout mechanism can interfere with the normal
    recovery process when both are triggered simultaneously.

         rc = -EAGAIN;
       // In smb2_negotiate()
       rc = -EHOSTDOWN;
    
    The server_unresponsive() timeout triggers cifs_reconnect(), which aborts
    ongoing mid requests and causes the ls command to receive -EAGAIN, leading
    to -EHOSTDOWN.
    
    Fix this by introducing a dedicated `neg_start` field to
    precisely tracks when the negotiate process begins. The timeout check
    now uses this accurate timestamp instead of `lstrp`, ensuring that:
    
    1. Timeout is only triggered after negotiate has actually run for 20s
    2. The mechanism doesn't interfere with concurrent recovery processes
    3. Uninitialized timestamps (value 0) don't trigger false timeouts

smb: client: fix readdir returning wrong type with POSIX extensions [+ + +]

Date:   Sun Jun 29 19:05:05 2025 +0200

    smb: client: fix readdir returning wrong type with POSIX extensions
    
    commit b8f89cb723b9e66f5dbd7199e4036fee34fb0de0 upstream.
    
    When SMB 3.1.1 POSIX Extensions are negotiated, userspace applications
    using readdir() or getdents() calls without stat() on each individual file
    (such as a simple "ls" or "find") would misidentify file types and exhibit
    strange behavior such as not descending into directories. The reason for
    this behavior is an oversight in the cifs_posix_to_fattr conversion
    function. Instead of extracting the entry type for cf_dtype from the
    properly converted cf_mode field, it tries to extract the type from the
    PDU. While the wire representation of the entry mode is similar in
    structure to POSIX stat(), the assignments of the entry types are
    different. Applying the S_DT macro to cf_mode instead yields the correct
    result. This is also what the equivalent function
    smb311_posix_info_to_fattr in inode.c already does for stat() etc.; which
    is why "ls -l" would give the correct file type but "ls" would not (as
    identified by the colors).

    When reconnecting a channel in smb2_reconnect_server(), a dummy tcon
    is passed down to smb2_reconnect() with ->query_interface
    uninitialized, so we can't call queue_delayed_work() on it.
    
    Fix the following warning by ensuring that we're queueing the delayed
    worker from correct tcon.

    spi: spi-fsl-dspi: Clear completion counter before initiating transfer
    
    [ Upstream commit fa60c094c19b97e103d653f528f8d9c178b6a5f5 ]
    
    In target mode, extra interrupts can be received between the end of a
    transfer and halting the module if the host continues sending more data.
    If the interrupt from this occurs after the reinit_completion() then the
    completion counter is left at a non-zero value. The next unrelated
    transfer initiated by userspace will then complete immediately without
    waiting for the interrupt or writing to the RX buffer.
    
    Fix it by resetting the counter before the transfer so that lingering
    values are cleared. This is done after clearing the FIFOs and the
    status register but before the transfer is initiated, so no interrupts
    should be received at this point resulting in other race conditions.

    Shawn and John reported a hang issue during system suspend as below:
    
     - USB gadget is enabled as Ethernet
     - There is data transfer over USB Ethernet (scp a big file between host
                                                 and device)
     - Device is going in/out suspend (echo mem > /sys/power/state)
    
    The root cause is the USB device controller is suspended but the USB bus
    is still active which caused the USB host continues to transfer data with
    device and the device continues to queue USB requests (in this case, a
    delayed TCP ACK packet trigger the issue) after controller is suspended,
    however the USB controller clock is already gated off. Then if udc driver
    access registers after that point, the system will hang.
    
    The correct way to avoid such issue is to disconnect device from host when
    the USB bus is not at suspend state. Then the host will receive disconnect
    event and stop data transfer in time. To continue make USB gadget device
    work after system resume, this will reconnect device automatically.
    
    To make usb wakeup work if USB bus is already at suspend state, this will
    keep connection for it only when USB device controller has enabled wakeup
    capability.

    usb: typec: altmodes/displayport: do not index invalid pin_assignments
    
    commit af4db5a35a4ef7a68046883bfd12468007db38f1 upstream.
    
    A poorly implemented DisplayPort Alt Mode port partner can indicate
    that its pin assignment capabilities are greater than the maximum
    value, DP_PIN_ASSIGN_F. In this case, calls to pin_assignment_show
    will cause a BRK exception due to an out of bounds array access.
    
    Prevent for loop in pin_assignment_show from accessing
    invalid values in pin_assignments by adding DP_PIN_ASSIGN_MAX
    value in typec_dp.h and using i < DP_PIN_ASSIGN_MAX as a loop
    condition.

    usb: typec: displayport: Fix potential deadlock
    
    commit 099cf1fbb8afc3771f408109f62bdec66f85160e upstream.
    
    The deadlock can occur due to a recursive lock acquisition of
    `cros_typec_altmode_data::mutex`.
    The call chain is as follows:
    1. cros_typec_altmode_work() acquires the mutex
    2. typec_altmode_vdm() -> dp_altmode_vdm() ->
    3. typec_altmode_exit() -> cros_typec_altmode_exit()
    4. cros_typec_altmode_exit() attempts to acquire the mutex again
    
    To prevent this, defer the `typec_altmode_exit()` call by scheduling
    it rather than calling it directly from within the mutex-protected
    context.

usb: xhci: quirk for data loss in ISOC transfers [+ + +]

Date:   Fri Jun 27 17:41:19 2025 +0300

    usb: xhci: quirk for data loss in ISOC transfers
    
    commit cbc889ab0122366f6cdbe3c28d477c683ebcebc2 upstream.
    
    During the High-Speed Isochronous Audio transfers, xHCI
    controller on certain AMD platforms experiences momentary data
    loss. This results in Missed Service Errors (MSE) being
    generated by the xHCI.
    
    The root cause of the MSE is attributed to the ISOC OUT endpoint
    being omitted from scheduling. This can happen when an IN
    endpoint with a 64ms service interval either is pre-scheduled
    prior to the ISOC OUT endpoint or the interval of the ISOC OUT
    endpoint is shorter than that of the IN endpoint. Consequently,
    the OUT service is neglected when an IN endpoint with a service
    interval exceeding 32ms is scheduled concurrently (every 64ms in
    this scenario).
    
    This issue is particularly seen on certain older AMD platforms.
    To mitigate this problem, it is recommended to adjust the service
    interval of the IN endpoint to not exceed 32ms (interval 8). This
    adjustment ensures that the OUT endpoint will not be bypassed,
    even if a smaller interval value is utilized.

    virtio-net: ensure the received length does not exceed allocated size
    
    commit 315dbdd7cdf6aa533829774caaf4d25f1fd20e73 upstream.
    
    In xdp_linearize_page, when reading the following buffers from the ring,
    we forget to check the received length with the true allocate size. This
    can lead to an out-of-bound read. This commit adds that missing check.

x86/traps: Initialize DR6 by writing its architectural reset value [+ + +]
Author: Xin Li (Intel) <[email protected]>
Date:   Sun Jul 6 07:43:08 2025 -0400

    x86/traps: Initialize DR6 by writing its architectural reset value
    
    [ Upstream commit 5f465c148c61e876b6d6eacd8e8e365f2d47758f ]
    
    Initialize DR6 by writing its architectural reset value to avoid
    incorrectly zeroing DR6 to clear DR6.BLD at boot time, which leads
    to a false bus lock detected warning.
    
    The Intel SDM says:
    
      1) Certain debug exceptions may clear bits 0-3 of DR6.
    
      2) BLD induced #DB clears DR6.BLD and any other debug exception
         doesn't modify DR6.BLD.
    
      3) RTM induced #DB clears DR6.RTM and any other debug exception
         sets DR6.RTM.
    
      To avoid confusion in identifying debug exceptions, debug handlers
      should set DR6.BLD and DR6.RTM, and clear other DR6 bits before
      returning.
    
    The DR6 architectural reset value 0xFFFF0FF0, already defined as
    macro DR6_RESERVED, satisfies these requirements, so just use it to
    reinitialize DR6 whenever needed.
    
    Since clear_all_debug_regs() no longer zeros all debug registers,
    rename it to initialize_debug_regs() to better reflect its current
    behavior.
    
    Since debug_read_clear_dr6() no longer clears DR6, rename it to
    debug_read_reset_dr6() to better reflect its current behavior.
