    9p: Avoid creating multiple slab caches with the same name
    
    [ Upstream commit 79efebae4afc2221fa814c3cae001bede66ab259 ]
    
    In the spirit of [1], avoid creating multiple slab caches with the same
    name. Instead, add the dev_name into the mix.

    9p: fix slab cache name creation for real
    
    commit a360f311f57a36e96d88fa8086b749159714dcd2 upstream.
    
    This was attempted by using the dev_name in the slab cache name, but as
    Omar Sandoval pointed out, that can be an arbitrary string, eg something
    like "/dev/root".  Which in turn trips verify_dirent_name(), which fails
    if a filename contains a slash.
    
    So just make it use a sequence counter, and make it an atomic_t to avoid
    any possible races or locking issues.

    Adds several vendor specific mixer quirks for RME's Class Compliant
    USB devices. These provide extra status information from the device
    otherwise not available.
    
    These include AES/SPDIF rate and status information, current system
    sampling rate and measured frequency. This information is especially
    useful in cases where device's clock is slaved to external clock
    source.

    ALSA: usb-audio: Add quirks for Dell WD19 dock
    
    [ Upstream commit 4413665dd6c528b31284119e3571c25f371e1c36 ]
    
    The WD19 family of docks has the same audio chipset as the WD15. This
    change enables jack detection on the WD19.
    
    We don't need the dell_dock_mixer_init quirk for the WD19. It is only
    needed because of the dell_alc4020_map quirk for the WD15 in
    mixer_maps.c, which disables the volume controls. Even for the WD15,
    this quirk was apparently only needed when the dock firmware was not
    updated.

    ALSA: usb-audio: Support jack detection on Dell dock
    
    [ Upstream commit 4b8ea38fabab45ad911a32a336416062553dfe9c ]
    
    The Dell WD15 dock has a headset and a line out port. Add support for
    detecting if a jack is inserted into one of these ports.
    For the headset jack, additionally determine if a mic is present.
    
    The WD15 contains an ALC4020 USB audio controller and ALC3263 audio codec
    from Realtek. It is a UAC 1 device, and UAC 1 does not support jack
    detection. Instead, jack detection works by sending HD Audio commands over
    vendor-type USB messages.
    
    I found out how it works by looking at USB captures on Windows.
    The audio codec is very similar to the one supported by
    sound/soc/codecs/rt298.c / rt298.h, some constant names and the mic
    detection are adapted from there. The realtek_add_jack function is adapted
    from build_connector_control in sound/usb/mixer.c.
    
    I tested this on a WD15 dock with the latest firmware.

bpf: use kvzmalloc to allocate BPF verifier environment [+ + +]

    bpf: use kvzmalloc to allocate BPF verifier environment
    
    [ Upstream commit 434247637c66e1be2bc71a9987d4c3f0d8672387 ]
    
    The kzmalloc call in bpf_check can fail when memory is very fragmented,
    which in turn can lead to an OOM kill.
    
    Use kvzmalloc to fall back to vmalloc when memory is too fragmented to
    allocate an order 3 sized bpf verifier environment.
    
    Admittedly this is not a very common case, and only happens on systems
    where memory has already been squeezed close to the limit, but this does
    not seem like much of a hot path, and it's a simple enough fix.

btrfs: reinitialize delayed ref list after deleting it from the list [+ + +]

    btrfs: reinitialize delayed ref list after deleting it from the list
    
    commit c9a75ec45f1111ef530ab186c2a7684d0a0c9245 upstream.
    
    At insert_delayed_ref() if we need to update the action of an existing
    ref to BTRFS_DROP_DELAYED_REF, we delete the ref from its ref head's
    ref_add_list using list_del(), which leaves the ref's add_list member
    not reinitialized, as list_del() sets the next and prev members of the
    list to LIST_POISON1 and LIST_POISON2, respectively.
    
    If later we end up calling drop_delayed_ref() against the ref, which can
    happen during merging or when destroying delayed refs due to a transaction
    abort, we can trigger a crash since at drop_delayed_ref() we call
    list_empty() against the ref's add_list, which returns false since
    the list was not reinitialized after the list_del() and as a consequence
    we call list_del() again at drop_delayed_ref(). This results in an
    invalid list access since the next and prev members are set to poison
    pointers, resulting in a splat if CONFIG_LIST_HARDENED and
    CONFIG_DEBUG_LIST are set or invalid poison pointer dereferences
    otherwise.
    
    So fix this by deleting from the list with list_del_init() instead.

dm cache: correct the number of origin blocks to match the target length [+ + +]
Author: Ming-Hung Tsai <mtsai@redhat.com>
Date:   Tue Oct 22 15:12:22 2024 +0800

    dm cache: correct the number of origin blocks to match the target length
    
    commit 235d2e739fcbe964c9ce179b4c991025662dcdb6 upstream.
    
    When creating a cache device, the actual size of the cache origin might
    be greater than the specified cache target length. In such case, the
    number of origin blocks should match the cache target length, not the
    full size of the origin device, since access beyond the cache target is
    not possible. This issue occurs when reducing the origin device size
    using lvm, as lvreduce preloads the new cache table before resuming the
    cache origin, which can result in incorrect sizes for the discard bitset
    and smq hotspot blocks.
    
    Reproduce steps:
    
    1. create a cache device consists of 4096 origin blocks
    
    dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
    dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
    dmsetup create corig --table "0 524288 linear /dev/sdc 262144"
    dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1 oflag=direct
    dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \
    /dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
    
    2. reduce the cache origin to 2048 oblocks, in lvreduce's approach
    
    dmsetup reload corig --table "0 262144 linear /dev/sdc 262144"
    dmsetup reload cache --table "0 262144 cache /dev/mapper/cmeta \
    /dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
    dmsetup suspend cache
    dmsetup suspend corig
    dmsetup suspend cdata
    dmsetup suspend cmeta
    dmsetup resume corig
    dmsetup resume cdata
    dmsetup resume cmeta
    dmsetup resume cache
    
    3. shutdown the cache, and check the number of discard blocks in
       superblock. The value is expected to be 2048, but actually is 4096.
    
    dmsetup remove cache corig cdata cmeta
    dd if=/dev/sdc bs=1c count=8 skip=224 2>/dev/null | hexdump -e '1/8 "%u\n"'

    dm cache: fix out-of-bounds access to the dirty bitset when resizing
    
    commit 792227719725497ce10a8039803bec13f89f8910 upstream.
    
    dm-cache checks the dirty bits of the cache blocks to be dropped when
    shrinking the fast device, but an index bug in bitset iteration causes
    out-of-bounds access.
    
    Reproduce steps:
    
    1. create a cache device of 1024 cache blocks (128 bytes dirty bitset)
    
    dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
    dmsetup create cdata --table "0 131072 linear /dev/sdc 8192"
    dmsetup create corig --table "0 524288 linear /dev/sdc 262144"
    dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1 oflag=direct
    dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \
    /dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
    
    2. shrink the fast device to 512 cache blocks, triggering out-of-bounds
       access to the dirty bitset (offset 0x80)
    
    dmsetup suspend cache
    dmsetup reload cdata --table "0 65536 linear /dev/sdc 8192"
    dmsetup resume cdata
    dmsetup resume cache

dm cache: fix potential out-of-bounds access on the first resume [+ + +]

Date:   Tue Oct 22 15:13:54 2024 +0800

    dm cache: fix potential out-of-bounds access on the first resume
    
    commit c0ade5d98979585d4f5a93e4514c2e9a65afa08d upstream.
    
    Out-of-bounds access occurs if the fast device is expanded unexpectedly
    before the first-time resume of the cache table. This happens because
    expanding the fast device requires reloading the cache table for
    cache_create to allocate new in-core data structures that fit the new
    size, and the check in cache_preresume is not performed during the
    first resume, leading to the issue.
    
    Reproduce steps:
    
    1. prepare component devices:
    
    dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
    dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
    dmsetup create corig --table "0 524288 linear /dev/sdc 262144"
    dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1 oflag=direct
    
    2. load a cache table of 512 cache blocks, and deliberately expand the
       fast device before resuming the cache, making the in-core data
       structures inadequate.
    
    dmsetup create cache --notable
    dmsetup reload cache --table "0 524288 cache /dev/mapper/cmeta \
    /dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
    dmsetup reload cdata --table "0 131072 linear /dev/sdc 8192"
    dmsetup resume cdata
    dmsetup resume cache
    
    3. suspend the cache to write out the in-core dirty bitset and hint
       array, leading to out-of-bounds access to the dirty bitset at offset
       0x40:
    
    dmsetup suspend cache

    dm cache: optimize dirty bit checking with find_next_bit when resizing
    
    commit f484697e619a83ecc370443a34746379ad99d204 upstream.
    
    When shrinking the fast device, dm-cache iteratively searches for a
    dirty bit among the cache blocks to be dropped, which is less efficient.
    Use find_next_bit instead, as it is twice as fast as the iterative
    approach with test_bit.

dm-unstriped: cast an operand to sector_t to prevent potential uint32_t overflow [+ + +]

    dm-unstriped: cast an operand to sector_t to prevent potential uint32_t overflow
    
    commit 5a4510c762fc04c74cff264cd4d9e9f5bf364bae upstream.
    
    This was found by a static analyzer.
    There may be a potential integer overflow issue in
    unstripe_ctr(). uc->unstripe_offset and uc->unstripe_width are
    defined as "sector_t"(uint64_t), while uc->unstripe,
    uc->chunk_size and uc->stripes are all defined as "uint32_t".
    The result of the calculation will be limited to "uint32_t"
    without correct casting.
    So, we recommend adding an extra cast to prevent potential
    integer overflow.

    drm/amdgpu: prevent NULL pointer dereference if ATIF is not supported
    
    commit a6dd15981c03f2cdc9a351a278f09b5479d53d2e upstream.
    
    acpi_evaluate_object() may return AE_NOT_FOUND (failure), which
    would result in dereferencing buffer.pointer (obj) while being NULL.
    
    Although this case may be unrealistic for the current code, it is
    still better to protect against possible bugs.

irqchip/gic-v3: Force propagation of the active state with a read-back [+ + +]

    irqchip/gic-v3: Force propagation of the active state with a read-back
    
    commit 464cb98f1c07298c4c10e714ae0c36338d18d316 upstream.
    
    Christoffer reports that on some implementations, writing to
    GICR_ISACTIVER0 (and similar GICD registers) can race badly with a guest
    issuing a deactivation of that interrupt via the system register interface.
    
    There are multiple reasons to this:
    
     - this uses an early write-acknoledgement memory type (nGnRE), meaning
       that the write may only have made it as far as some interconnect
       by the time the store is considered "done"
    
     - the GIC itself is allowed to buffer the write until it decides to
       take it into account (as long as it is in finite time)
    
    The effects are that the activation may not have taken effect by the time
    the kernel enters the guest, forcing an immediate exit, or that a guest
    deactivation occurs before the interrupt is active, doing nothing.
    
    In order to guarantee that the write to the ISACTIVER register has taken
    effect, read back from it, forcing the interconnect to propagate the write,
    and the GIC to process the write before returning the read.

    as reported by Coverity, if reading SNR registers fail, a negative
    number will be returned, causing an underflow when reading SNR
    registers.
    
    Prevent that.

    media: dvb_frontend: don't play tricks with underflow values
    
    [ Upstream commit 9883a4d41aba7612644e9bb807b971247cea9b9d ]
    
    fepriv->auto_sub_step is unsigned. Setting it to -1 is just a
    trick to avoid calling continue, as reported by Coverity.
    
    It relies to have this code just afterwards:
    
            if (!ready) fepriv->auto_sub_step++;
    
    Simplify the code by simply setting it to zero and use
    continue to return to the while loop.

    media: dvbdev: prevent the risk of out of memory access
    
    [ Upstream commit 972e63e895abbe8aa1ccbdbb4e6362abda7cd457 ]
    
    The dvbdev contains a static variable used to store dvb minors.
    
    The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set
    or not. When not set, dvb_register_device() won't check for
    boundaries, as it will rely that a previous call to
    dvb_register_adapter() would already be enforcing it.
    
    On a similar way, dvb_device_open() uses the assumption
    that the register functions already did the needed checks.
    
    This can be fragile if some device ends using different
    calls. This also generate warnings on static check analysers
    like Coverity.
    
    So, add explicit guards to prevent potential risk of OOM issues.

net: hns3: fix kernel crash when uninstalling driver [+ + +]

    net: hns3: fix kernel crash when uninstalling driver
    
    [ Upstream commit df3dff8ab6d79edc942464999d06fbaedf8cdd18 ]
    
    When the driver is uninstalled and the VF is disabled concurrently, a
    kernel crash occurs. The reason is that the two actions call function
    pci_disable_sriov(). The num_VFs is checked to determine whether to
    release the corresponding resources. During the second calling, num_VFs
    is not 0 and the resource release function is called. However, the
    corresponding resource has been released during the first invoking.
    Therefore, the problem occurs:

    Reproducer uses faultinject facility to fail ocfs2_xa_remove() ->
    ocfs2_xa_value_truncate() with -ENOMEM.
    
    In this case the comment mentions that we can return 0 if
    ocfs2_xa_cleanup_value_truncate() is going to wipe the entry
    anyway. But the following 'rc' check is wrong and execution flow do
    'ocfs2_xa_remove_entry(loc);' twice:
    * 1st: in ocfs2_xa_cleanup_value_truncate();
    * 2nd: returning back to ocfs2_xa_remove() instead of going to 'out'.
    
    Fix this by skipping the 2nd removal of the same entry and making
    syzkaller repro happy.

powerpc/powernv: Free name on error in opal_event_init() [+ + +]

    powerpc/powernv: Free name on error in opal_event_init()
    
    [ Upstream commit cf8989d20d64ad702a6210c11a0347ebf3852aa7 ]
    
    In opal_event_init() if request_irq() fails name is not freed, leading
    to a memory leak. The code only runs at boot time, there's no way for a
    user to trigger it, so there's no security impact.
    
    Fix the leak by freeing name in the error path.

     search_nested_keyrings+0x90e/0xe90 security/keys/keyring.c:793
    
    This issue was also reported by syzbot.
    
    It can be reproduced by following these steps(more details [1]):
    1. Obtain more than 32 inputs that have similar hashes, which ends with the
       pattern '0xxxxxxxe6'.
    2. Reboot and add the keys obtained in step 1.
    
    The reproducer demonstrates how this issue happened:
    1. In the search_nested_keyrings function, when it iterates through the
       slots in a node(below tag ascend_to_node), if the slot pointer is meta
       and node->back_pointer != NULL(it means a root), it will proceed to
       descend_to_node. However, there is an exception. If node is the root,
       and one of the slots points to a shortcut, it will be treated as a
       keyring.
    2. Whether the ptr is keyring decided by keyring_ptr_is_keyring function.
       However, KEYRING_PTR_SUBTYPE is 0x2UL, the same as
       ASSOC_ARRAY_PTR_SUBTYPE_MASK.
    3. When 32 keys with the similar hashes are added to the tree, the ROOT
       has keys with hashes that are not similar (e.g. slot 0) and it splits
       NODE A without using a shortcut. When NODE A is filled with keys that
       all hashes are xxe6, the keys are similar, NODE A will split with a
       shortcut. Finally, it forms the tree as shown below, where slot 6 points
       to a shortcut.
    
                          NODE A
                  +------>+---+
          ROOT    |       | 0 | xxe6
          +---+   |       +---+
     xxxx | 0 | shortcut  :   : xxe6
          +---+   |       +---+
     xxe6 :   :   |       |   | xxe6
          +---+   |       +---+
          | 6 |---+       :   : xxe6
          +---+           +---+
     xxe6 :   :           | f | xxe6
          +---+           +---+
     xxe6 | f |
          +---+
    
    4. As mentioned above, If a slot(slot 6) of the root points to a shortcut,
       it may be mistakenly transferred to a key*, leading to a read
       out-of-bounds read.
    
    To fix this issue, one should jump to descend_to_node if the ptr is a
    shortcut, regardless of whether the node is root or not.

    sound: Make CONFIG_SND depend on INDIRECT_IOMEM instead of UML
    
    [ Upstream commit ad6639f143a0b42d7fb110ad14f5949f7c218890 ]
    
    When building for the UM arch and neither INDIRECT_IOMEM=y, nor
    HAS_IOMEM=y is selected, it will fall back to the implementations from
    asm-generic/io.h for IO memcpy. But these fall-back functions just do a
    memcpy. So, instead of depending on UML, add dependency on 'HAS_IOMEM ||
    INDIRECT_IOMEM'.

Date:   Tue Oct 29 23:13:38 2024 +0800

    usb: musb: sunxi: Fix accessing an released usb phy
    
    commit 498dbd9aea205db9da674994b74c7bf8e18448bd upstream.
    
    Commit 6ed05c68cbca ("usb: musb: sunxi: Explicitly release USB PHY on
    exit") will cause that usb phy @glue->xceiv is accessed after released.
    
    1) register platform driver @sunxi_musb_driver
    // get the usb phy @glue->xceiv
    sunxi_musb_probe() -> devm_usb_get_phy().
    
    2) register and unregister platform driver @musb_driver
    musb_probe() -> sunxi_musb_init()
    use the phy here
    //the phy is released here
    musb_remove() -> sunxi_musb_exit() -> devm_usb_put_phy()
    
    3) register @musb_driver again
    musb_probe() -> sunxi_musb_init()
    use the phy here but the phy has been released at 2).
    ...
    
    Fixed by reverting the commit, namely, removing devm_usb_put_phy()
    from sunxi_musb_exit().

vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans [+ + +]

    vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans
    
    commit 6ca575374dd9a507cdd16dfa0e78c2e9e20bd05f upstream.
    
    During loopback communication, a dangling pointer can be created in
    vsk->trans, potentially leading to a Use-After-Free condition.  This
    issue is resolved by initializing vsk->trans to NULL.
