    ALSA: hda/ca0132: add quirk for EVGA Z390 DARK
    
    commit 0c423e2ffa7edd3f8f9bcf17ce73fa9c7509b99e upstream.
    
    The Z390 DARK mainboard uses a CA0132 audio controller. The quirk is
    needed to enable surround sound and 3.5mm headphone jack handling in
    the front audio connector as well as in the rear of the board when in
    stereo mode.
    
    Page 97 of the linked manual contains instructions to setup the
    controller.

arm64: efi: Fix handling of misaligned runtime regions and drop warning [+ + +]

    arm64: efi: Fix handling of misaligned runtime regions and drop warning
    
    commit 9b9eaee9828fe98b030cf43ac50065a54a2f5d52 upstream.
    
    Currently, when mapping the EFI runtime regions in the EFI page tables,
    we complain about misaligned regions in a rather noisy way, using
    WARN().
    
    Not only does this produce a lot of irrelevant clutter in the log, it is
    factually incorrect, as misaligned runtime regions are actually allowed
    by the EFI spec as long as they don't require conflicting memory types
    within the same 64k page.
    
    So let's drop the warning, and tweak the code so that we
    - take both the start and end of the region into account when checking
      for misalignment
    - only revert to RWX mappings for non-code regions if misaligned code
      regions are also known to exist.

    ata: libata-scsi: fix SYNCHRONIZE CACHE (16) command failure
    
    commit ea045fd344cb15c164e9ffc8b8cffb6883df8475 upstream.
    
    SAT SCSI/ATA Translation specification requires SCSI SYNCHRONIZE CACHE
    (10) and (16) commands both shall be translated to ATA flush command.
    Also, ZBC Zoned Block Commands specification mandates SYNCHRONIZE CACHE
    (16) command support. However, libata translates only SYNCHRONIZE CACHE
    (10). This results in SYNCHRONIZE CACHE (16) command failures on SATA
    drives and then libata translation does not conform to ZBC. To avoid the
    failure, add support for SYNCHRONIZE CACHE (16).

    [ Upstream commit 6d81ea3765dfa6c8a20822613c81edad1c4a16a0 ]
    
    During the error recovery sequence, the rtnl_lock is not held for the
    entire duration and some datastructures may be freed during the sequence.
    Check for the BNXT_STATE_OPEN flag instead of netif_running() to ensure
    that the device is fully operational before proceeding to reconfigure
    the coalescing settings.
    
    This will fix a possible crash like this:

    In the bnxt_en driver ndo_rx_flow_steer returns '0' whenever an entry
    that we are attempting to steer is already found.  This is not the
    correct behavior.  The return code should be the value/index that
    corresponds to the entry.  Returning zero all the time causes the
    RFS records to be incorrect unless entry '0' is the correct one.  As
    flows migrate to different cores this can create entries that are not
    correct.

bpf: Add helper macro bpf_for_each_reg_in_vstate [+ + +]
Author: Kumar Kartikeya Dwivedi <[email protected]>
Date:   Sun Sep 4 22:41:28 2022 +0200

    bpf: Add helper macro bpf_for_each_reg_in_vstate
    
    [ Upstream commit b239da34203f49c40b5d656220c39647c3ff0b3c ]
    
    For a lot of use cases in future patches, we will want to modify the
    state of registers part of some same 'group' (e.g. same ref_obj_id). It
    won't just be limited to releasing reference state, but setting a type
    flag dynamically based on certain actions, etc.
    
    Hence, we need a way to easily pass a callback to the function that
    iterates over all registers in current bpf_verifier_state in all frames
    upto (and including) the curframe.
    
    While in C++ we would be able to easily use a lambda to pass state and
    the callback together, sadly we aren't using C++ in the kernel. The next
    best thing to avoid defining a function for each case seems like
    statement expressions in GNU C. The kernel already uses them heavily,
    hence they can passed to the macro in the style of a lambda. The
    statement expression will then be substituted in the for loop bodies.
    
    Variables __state and __reg are set to current bpf_func_state and reg
    for each invocation of the expression inside the passed in verifier
    state.
    
    Then, convert mark_ptr_or_null_regs, clear_all_pkt_pointers,
    release_reference, find_good_pkt_pointers, find_equal_scalars to
    use bpf_for_each_reg_in_vstate.

    [ Upstream commit f1db20814af532f85e091231223e5e4818e8464b ]
    
    Some helper functions will allocate memory. To avoid memory leaks, the
    verifier requires the eBPF program to release these memories by calling
    the corresponding helper functions.
    
    When a resource is released, all pointer registers corresponding to the
    resource should be invalidated. The verifier use release_references() to
    do this job, by apply  __mark_reg_unknown() to each relevant register.
    
    It will give these registers the type of SCALAR_VALUE. A register that
    will contain a pointer value at runtime, but of type SCALAR_VALUE, which
    may allow the unprivileged user to get a kernel pointer by storing this
    register into a map.
    
    Using __mark_reg_not_init() while NOT allow_ptr_leaks can mitigate this
    problem.

    [ Upstream commit 6d94e741a8ff818e5518da8257f5ca0aaed1f269 ]
    
    This patch adds the verifier support to recognize inlined branch conditions.
    The LLVM knows that the branch evaluates to the same value, but the verifier
    couldn't track it. Hence causing valid programs to be rejected.
    The potential LLVM workaround: https://reviews.llvm.org/D87428
    can have undesired side effects, since LLVM doesn't know that
    skb->data/data_end are being compared. LLVM has to introduce extra boolean
    variable and use inline_asm trick to force easier for the verifier assembly.
    
    Instead teach the verifier to recognize that
    r1 = skb->data;
    r1 += 10;
    r2 = skb->data_end;
    if (r1 > r2) {
      here r1 points beyond packet_end and
      subsequent
      if (r1 > r2) // always evaluates to "true".

    When using bpftool to pin {PROG, MAP, LINK} without FILE,
    segmentation fault will occur. The reson is that the lack
    of FILE will cause strlen to trigger NULL pointer dereference.
    The corresponding stacktrace is shown below:
    
    do_pin
      do_pin_any
        do_pin_fd
          mount_bpffs_for_pin

    Fix it by adding validation to the common process.

    btrfs: selftests: fix wrong error check in btrfs_free_dummy_root()
    
    commit 9b2f20344d450137d015b380ff0c2e2a6a170135 upstream.
    
    The btrfs_alloc_dummy_root() uses ERR_PTR as the error return value
    rather than NULL, if error happened, there will be a NULL pointer
    dereference:

can: af_can: fix NULL pointer dereference in can_rx_register() [+ + +]

    can: af_can: fix NULL pointer dereference in can_rx_register()
    
    [ Upstream commit 8aa59e355949442c408408c2d836e561794c40a1 ]
    
    It causes NULL pointer dereference when testing as following:
    (a) use syscall(__NR_socket, 0x10ul, 3ul, 0) to create netlink socket.
    (b) use syscall(__NR_sendmsg, ...) to create bond link device and vxcan
        link device, and bind vxcan device to bond device (can also use
        ifenslave command to bind vxcan device to bond device).
    (c) use syscall(__NR_socket, 0x1dul, 3ul, 1) to create CAN socket.
    (d) use syscall(__NR_bind, ...) to bind the bond device to CAN socket.
    
    The bond device invokes the can-raw protocol registration interface to
    receive CAN packets. However, ml_priv is not allocated to the dev,
    dev_rcv_lists is assigned to NULL in can_rx_register(). In this case,
    it will occur the NULL pointer dereference issue.

    commit 7176a6a8982d311e50a7c1168868d26e65bbba19 upstream.
    
    tx_submit is supposed to push the current transaction descriptor to a
    pending queue, waiting for issue_pending() to be called. issue_pending()
    must start the transfer, not tx_submit(), thus remove atc_dostart() from
    atc_tx_submit(). Clients of at_xdmac that assume that tx_submit() starts
    the transfer must be updated and call dma_async_issue_pending() if they
    miss to call it.
    The vdbg print was moved to after the lock is released. It is desirable to
    do the prints without the lock held if possible, and because the if
    statement disappears there's no reason why to do the print while holding
    the lock.

    was wrong as if there were any descriptors in the submitted list they were
    moved to the issued list without actually issuing them to the controller,

    commit c6babed879fbe82796a601bf097649e07382db46 upstream.
    
    atc_complete_all() had concurrency bugs, thus remove it:
    1/ atc_complete_all() in its entirety was buggy, as when the atchan->queue
    list (the one that contains descriptors that are not yet issued to the
    hardware) contained descriptors, it fired just the first from the
    atchan->queue, but moved all the desc from atchan->queue to
    atchan->active_list and considered them all as fired. This could result in
    calling the completion of a descriptor that was not yet issued to the
    hardware.
    2/ when in tasklet at atc_advance_work() time, atchan->active_list was
    queried without holding the lock of the chan. This can result in
    atchan->active_list concurrency problems between the tasklet and
    issue_pending().

    dmaengine: at_hdmac: Fix premature completion of desc in issue_pending
    
    commit fcd37565efdaffeac179d0f0ce980ac79bfdf569 upstream.
    
    Multiple calls to atc_issue_pending() could result in a premature
    completion of a descriptor from the atchan->active list, as the method
    always completed the first active descriptor from the list. Instead,
    issue_pending() should just take the first transaction descriptor from the
    pending queue, move it to active_list and start the transfer.

    commit 6e5ad28d16f082efeae3d0bd2e31f24bed218019 upstream.
    
    Now that the complete callback call was removed from
    device_terminate_all(), we can protect the atchan->status with the channel
    lock. The atomic bitops on atchan->status do not substitute proper locking
    on the status, as one could still modify the status after the lock was
    dropped in atc_terminate_all() but before the atomic bitops were executed.

    Cyclic channels must too call issue_pending in order to start a transfer.
    Start the transfer in issue_pending regardless of the type of channel.
    This wrongly worked before, because in the past the transfer was started
    at tx_submit level when only a desc in the transfer list.

    drm/i915/dmabuf: fix sg_table handling in map_dma_buf
    
    commit f90daa975911961b65070ec72bd7dd8d448f9ef7 upstream.
    
    We need to iterate over the original entries here for the sg_table,
    pulling out the struct page for each one, to be remapped. However
    currently this incorrectly iterates over the final dma mapped entries,
    which is likely just one gigantic sg entry if the iommu is enabled,
    leading to us only mapping the first struct page (and any physically
    contiguous pages following it), even if there is potentially lots more
    data to follow.

    drm/vc4: Fix missing platform_unregister_drivers() call in vc4_drm_register()
    
    [ Upstream commit cf53db768a8790fdaae2fa3a81322b080285f7e5 ]
    
    A problem about modprobe vc4 failed is triggered with the following log
    given:
    
     [  420.327987] Error: Driver 'vc4_hvs' is already registered, aborting...
     [  420.333904] failed to register platform driver vc4_hvs_driver [vc4]: -16
     modprobe: ERROR: could not insert 'vc4': Device or resource busy
    
    The reason is that vc4_drm_register() returns platform_driver_register()
    directly without checking its return value, if platform_driver_register()
    fails, it returns without unregistering all the vc4 drivers, resulting the
    vc4 can never be installed later.
    A simple call graph is shown as below:
    
     vc4_drm_register()
       platform_register_drivers() # all vc4 drivers are registered
       platform_driver_register()
         driver_register()
           bus_add_driver()
             priv = kzalloc(...) # OOM happened
       # return without unregister drivers
    
    Fixing this problem by checking the return value of
    platform_driver_register() and do platform_unregister_drivers() if
    error happened.

    fuse: fix readdir cache race
    
    [ Upstream commit 9fa248c65bdbf5af0a2f74dd38575acfc8dfd2bf ]
    
    There's a race in fuse's readdir cache that can result in an uninitilized
    page being read.  The page lock is supposed to prevent this from happening
    but in the following case it doesn't:
    
    Two fuse_add_dirent_to_cache() start out and get the same parameters
    (size=0,offset=0).  One of them wins the race to create and lock the page,
    after which it fills in data, sets rdc.size and unlocks the page.
    
    In the meantime the page gets evicted from the cache before the other
    instance gets to run.  That one also creates the page, but finds the
    size to be mismatched, bails out and leaves the uninitialized page in the
    cache.
    
    Fix by marking a filled page uptodate and ignoring non-uptodate pages.

    When new bond device is created, the default type of the bond device is
    ether. And the bond device is up, bpq_device_event() receives the message
    and creates a new bpq device. In this case, the reference count value of
    dev is hold once. But after "ifenslave -f bond2 rose1" command is
    executed, the type of the bond device is changed to rose. When the bond
    device is unregistered, bpq_device_event() will not put the dev reference
    count.

KVM: s390: pv: don't allow userspace to set the clock under PV [+ + +]
Author: Nico Boehr <[email protected]>

    KVM: s390: pv: don't allow userspace to set the clock under PV
    
    [ Upstream commit 6973091d1b50ab4042f6a2d495f59e9db3662ab8 ]
    
    When running under PV, the guest's TOD clock is under control of the
    ultravisor and the hypervisor isn't allowed to change it. Hence, don't
    allow userspace to change the guest's TOD clock by returning
    -EOPNOTSUPP.
    
    When userspace changes the guest's TOD clock, KVM updates its
    kvm.arch.epoch field and, in addition, the epoch field in all state
    descriptions of all VCPUs.
    
    But, under PV, the ultravisor will ignore the epoch field in the state
    description and simply overwrite it on next SIE exit with the actual
    guest epoch. This leads to KVM having an incorrect view of the guest's
    TOD clock: it has updated its internal kvm.arch.epoch field, but the
    ultravisor ignores the field in the state description.
    
    Whenever a guest is now waiting for a clock comparator, KVM will
    incorrectly calculate the time when the guest should wake up, possibly
    causing the guest to sleep for much longer than expected.
    
    With this change, kvm_s390_set_tod() will now take the kvm->lock to be
    able to call kvm_s390_pv_is_protected(). Since kvm_s390_set_tod_clock()
    also takes kvm->lock, use __kvm_s390_set_tod_clock() instead.
    
    The function kvm_s390_set_tod_clock is now unused, hence remove it.
    Update the documentation to indicate the TOD clock attr calls can now
    return -EOPNOTSUPP.

KVM: s390x: fix SCK locking [+ + +]

    KVM: s390x: fix SCK locking
    
    [ Upstream commit c0573ba5c5a2244dc02060b1f374d4593c1d20b7 ]
    
    When handling the SCK instruction, the kvm lock is taken, even though
    the vcpu lock is already being held. The normal locking order is kvm
    lock first and then vcpu lock. This is can (and in some circumstances
    does) lead to deadlocks.
    
    The function kvm_s390_set_tod_clock is called both by the SCK handler
    and by some IOCTLs to set the clock. The IOCTLs will not hold the vcpu
    lock, so they can safely take the kvm lock. The SCK handler holds the
    vcpu lock, but will also somehow need to acquire the kvm lock without
    relinquishing the vcpu lock.
    
    The solution is to factor out the code to set the clock, and provide
    two wrappers. One is called like the original function and does the
    locking, the other is called kvm_s390_try_set_tod_clock and uses
    trylock to try to acquire the kvm lock. This new wrapper is then used
    in the SCK handler. If locking fails, -EAGAIN is returned, which is
    eventually propagated to userspace, thus also freeing the vcpu lock and
    allowing for forward progress.
    
    This is not the most efficient or elegant way to solve this issue, but
    the SCK instruction is deprecated and its performance is not critical.
    
    The goal of this patch is just to provide a simple but correct way to
    fix the bug.

    [ Upstream commit 80df4706357a5a06bbbc70273bf2611df1ceee04 ]
    
    macsec_is_configured incorrectly uses secy->n_rx_sc to check if some
    RXSCs exist. secy->n_rx_sc only counts the number of active RXSCs, but
    there can also be inactive SCs as well, which may be stored in the
    driver (in case we're disabling offloading), or would have to be
    pushed to the device (in case we're trying to enable offloading).
    
    As long as RXSCs active on creation and never turned off, the issue is
    not visible.

    [ Upstream commit 73a4b31c9d11f98ae3bc5286d5382930adb0e9c7 ]

    add the SCI to the header or not.
    
    This logic is currently broken when we create a new RXSC and turn it
    off at creation, as create_rx_sc always sets ->active to true (and
    immediately uses that to increment n_rx_sc), and only later
    macsec_add_rxsc sets rx_sc->active.

mmc: cqhci: Provide helper for resetting both SDHCI and CQHCI [+ + +]
Author: Brian Norris <[email protected]>
Date:   Wed Oct 26 12:42:03 2022 -0700

    mmc: cqhci: Provide helper for resetting both SDHCI and CQHCI
    
    commit ebb5fd38f41132e6924cb33b647337f4a5d5360c upstream.
    
    Several SDHCI drivers need to deactivate command queueing in their reset
    hook (see sdhci_cqhci_reset() / sdhci-pci-core.c, for example), and
    several more are coming.
    
    Those reset implementations have some small subtleties (e.g., ordering
    of initialization of SDHCI vs. CQHCI might leave us resetting with a
    NULL ->cqe_private), and are often identical across different host
    drivers.
    
    We also don't want to force a dependency between SDHCI and CQHCI, or
    vice versa; non-SDHCI drivers use CQHCI, and SDHCI drivers might support
    command queueing through some other means.
    
    So, implement a small helper, to avoid repeating the same mistakes in
    different drivers. Simply stick it in a header, because it's so small it
    doesn't deserve its own module right now, and inlining to each driver is
    pretty reasonable.
    
    This is marked for -stable, as it is an important prerequisite patch for
    several SDHCI controller bugfixes that follow.

    mmc: sdhci-of-arasan: Fix SDHCI_RESET_ALL for CQHCI
    
    commit 5d249ac37fc2396e8acc1adb0650cdacae5a990d upstream.
    
    SDHCI_RESET_ALL resets will reset the hardware CQE state, but we aren't
    tracking that properly in software. When out of sync, we may trigger
    various timeouts.
    
    It's not typical to perform resets while CQE is enabled, but one
    particular case I hit commonly enough: mmc_suspend() -> mmc_power_off().
    Typically we will eventually deactivate CQE (cqhci_suspend() ->
    cqhci_deactivate()), but that's not guaranteed -- in particular, if
    we perform a partial (e.g., interrupted) system suspend.
    
    The same bug was already found and fixed for two other drivers, in v5.7
    and v5.9:
    
      5cf583f1fb9c ("mmc: sdhci-msm: Deactivate CQE during SDHC reset")
      df57d73276b8 ("mmc: sdhci-pci: Fix SDHCI_RESET_ALL for CQHCI for Intel
                     GLK-based controllers")
    
    The latter is especially prescient, saying "other drivers using CQHCI
    might benefit from a similar change, if they also have CQHCI reset by
    SDHCI_RESET_ALL."
    
    So like these other patches, deactivate CQHCI when resetting the
    controller. Do this via the new sdhci_and_cqhci_reset() helper.
    
    This patch depends on (and should not compile without) the patch
    entitled "mmc: cqhci: Provide helper for resetting both SDHCI and
    CQHCI".

    never releases the CPU but calls down_trylock(&cmd→sem) in a busy loop.
    On a single processor system, this leads to a deadlock as the kernel
    thread which executes mlx5_cmd_invoke() never gets scheduled. Fix this,
    by adding the cond_resched() call to the loop, allow the command
    completion kernel thread to execute.

    this. This is not completely reversible, since some resources aren't
    cleaned up properly, but that can be addressed later.

net: gso: fix panic on frag_list with mixed head alloc types [+ + +]

    net: gso: fix panic on frag_list with mixed head alloc types
    
    [ Upstream commit 9e4b7a99a03aefd37ba7bb1f022c8efab5019165 ]
    
    Since commit 3dcbdb134f32 ("net: gso: Fix skb_segment splat when
    splitting gso_size mangled skb having linear-headed frag_list"), it is
    allowed to change gso_size of a GRO packet. However, that commit assumes
    that "checking the first list_skb member suffices; i.e if either of the
    list_skb members have non head_frag head, then the first one has too".
    
    It turns out this assumption does not hold. We've seen BUG_ON being hit
    in skb_segment when skbs on the frag_list had differing head_frag with
    the vmxnet3 driver. This happens because __netdev_alloc_skb and
    __napi_alloc_skb can return a skb that is page backed or kmalloced
    depending on the requested size. As the result, the last small skb in
    the GRO packet can be kmalloced.
    
    There are three different locations where this can be fixed:
    
    (1) We could check head_frag in GRO and not allow GROing skbs with
        different head_frag. However, that would lead to performance
        regression on normal forward paths with unmodified gso_size, where
        !head_frag in the last packet is not a problem.
    
    (2) Set a flag in bpf_skb_net_grow and bpf_skb_net_shrink indicating
        that NETIF_F_SG is undesirable. That would need to eat a bit in
        sk_buff. Furthermore, that flag can be unset when all skbs on the
        frag_list are page backed. To retain good performance,
        bpf_skb_net_grow/shrink would have to walk the frag_list.
    
    (3) Walk the frag_list in skb_segment when determining whether
        NETIF_F_SG should be cleared. This of course slows things down.
    
    This patch implements (3). To limit the performance impact in
    skb_segment, the list is walked only for skbs with SKB_GSO_DODGY set
    that have gso_size changed. Normal paths thus will not hit it.
    
    We could check only the last skb but since we need to walk the whole
    list anyway, let's stay on the safe side.

    net: lapbether: fix issue of dev reference count leakage in lapbeth_device_event()
    
    [ Upstream commit 531705a765493655472c993627106e19f7e5a6d2 ]
    
    When following tests are performed, it will cause dev reference counting
    leakage.
    a)ip link add bond2 type bond mode balance-rr
    b)ip link set bond2 up
    c)ifenslave -f bond2 rose1
    d)ip link del bond2
    
    When new bond device is created, the default type of the bond device is
    ether. And the bond device is up, lapbeth_device_event() receives the
    message and creates a new lapbeth device. In this case, the reference
    count value of dev is hold once. But after "ifenslave -f bond2 rose1"
    command is executed, the type of the bond device is changed to rose. When
    the bond device is unregistered, lapbeth_device_event() will not put the
    dev reference count.

nilfs2: fix deadlock in nilfs_count_free_blocks() [+ + +]
Author: Ryusuke Konishi <[email protected]>
Date:   Sat Oct 29 13:49:12 2022 +0900

    nilfs2: fix deadlock in nilfs_count_free_blocks()
    
    commit 8ac932a4921a96ca52f61935dbba64ea87bbd5dc upstream.
    
    A semaphore deadlock can occur if nilfs_get_block() detects metadata
    corruption while locating data blocks and a superblock writeback occurs at
    the same time:
    
    task 1                               task 2
    ------                               ------
    * A file operation *
    nilfs_truncate()
      nilfs_get_block()
        down_read(rwsem A) <--
        nilfs_bmap_lookup_contig()
          ...                            generic_shutdown_super()
                                           nilfs_put_super()
                                             * Prepare to write superblock *
                                             down_write(rwsem B) <--
                                             nilfs_cleanup_super()
          * Detect b-tree corruption *         nilfs_set_log_cursor()
          nilfs_bmap_convert_error()             nilfs_count_free_blocks()
            __nilfs_error()                        down_read(rwsem A) <--
              nilfs_set_error()
                down_write(rwsem B) <--
    
                               *** DEADLOCK ***
    
    Here, nilfs_get_block() readlocks rwsem A (= NILFS_MDT(dat_inode)->mi_sem)
    and then calls nilfs_bmap_lookup_contig(), but if it fails due to metadata
    corruption, __nilfs_error() is called from nilfs_bmap_convert_error()
    inside the lock section.
    
    Since __nilfs_error() calls nilfs_set_error() unless the filesystem is
    read-only and nilfs_set_error() attempts to writelock rwsem B (=
    nilfs->ns_sem) to write back superblock exclusively, hierarchical lock
    acquisition occurs in the order rwsem A -> rwsem B.
    
    Now, if another task starts updating the superblock, it may writelock
    rwsem B during the lock sequence above, and can deadlock trying to
    readlock rwsem A in nilfs_count_free_blocks().
    
    However, there is actually no need to take rwsem A in
    nilfs_count_free_blocks() because it, within the lock section, only reads
    a single integer data on a shared struct with
    nilfs_sufile_get_ncleansegs().  This has been the case after commit
    aa474a220180 ("nilfs2: add local variable to cache the number of clean
    segments"), that is, even before this bug was introduced.
    
    So, this resolves the deadlock problem by just not taking the semaphore in
    nilfs_count_free_blocks().

nilfs2: fix use-after-free bug of ns_writer on remount [+ + +]
Author: Ryusuke Konishi <[email protected]>
Date:   Fri Nov 4 23:29:59 2022 +0900

    nilfs2: fix use-after-free bug of ns_writer on remount
    
    commit 8cccf05fe857a18ee26e20d11a8455a73ffd4efd upstream.
    
    If a nilfs2 filesystem is downgraded to read-only due to metadata
    corruption on disk and is remounted read/write, or if emergency read-only
    remount is performed, detaching a log writer and synchronizing the
    filesystem can be done at the same time.
    
    In these cases, use-after-free of the log writer (hereinafter
    nilfs->ns_writer) can happen as shown in the scenario below:
    
     Task1                               Task2
     --------------------------------    ------------------------------
     nilfs_construct_segment
       nilfs_segctor_sync
         init_wait
         init_waitqueue_entry
         add_wait_queue
         schedule
                                         nilfs_remount (R/W remount case)
                                           nilfs_attach_log_writer
                                             nilfs_detach_log_writer
                                               nilfs_segctor_destroy
                                                 kfree
         finish_wait
           _raw_spin_lock_irqsave
             __raw_spin_lock_irqsave
               do_raw_spin_lock
                 debug_spin_lock_before  <-- use-after-free
    
    While Task1 is sleeping, nilfs->ns_writer is freed by Task2.  After Task1
    waked up, Task1 accesses nilfs->ns_writer which is already freed.  This
    scenario diagram is based on the Shigeru Yoshida's post [1].
    
    This patch fixes the issue by not detaching nilfs->ns_writer on remount so
    that this UAF race doesn't happen.  Along with this change, this patch
    also inserts a few necessary read-only checks with superblock instance
    where only the ns_writer pointer was used to check if the filesystem is
    read-only.

perf stat: Fix printing os->prefix in CSV metrics output [+ + +]
Author: Athira Rajeev <[email protected]>
Date:   Tue Oct 18 14:26:04 2022 +0530

    perf stat: Fix printing os->prefix in CSV metrics output
    
    [ Upstream commit ad353b710c7493df3d4fc2d3a51819126bed2e81 ]
    
    'perf stat' with CSV output option prints an extra empty string as first
    field in metrics output line.  Sample output below:
    
            # ./perf stat -x, --per-socket -a -C 1 ls
            S0,1,1.78,msec,cpu-clock,1785146,100.00,0.973,CPUs utilized
            S0,1,26,,context-switches,1781750,100.00,0.015,M/sec
            S0,1,1,,cpu-migrations,1780526,100.00,0.561,K/sec
            S0,1,1,,page-faults,1779060,100.00,0.561,K/sec
            S0,1,875807,,cycles,1769826,100.00,0.491,GHz
            S0,1,85281,,stalled-cycles-frontend,1767512,100.00,9.74,frontend cycles idle
            S0,1,576839,,stalled-cycles-backend,1766260,100.00,65.86,backend cycles idle
            S0,1,288430,,instructions,1762246,100.00,0.33,insn per cycle
    ====>   ,S0,1,,,,,,,2.00,stalled cycles per insn
    
    The above command line uses field separator as "," via "-x," option and
    per-socket option displays socket value as first field. But here the
    last line for "stalled cycles per insn" has "," in the beginning.
    
    Sample output using interval mode:
    
            # ./perf stat -I 1000 -x, --per-socket -a -C 1 ls
            0.001813453,S0,1,1.87,msec,cpu-clock,1872052,100.00,0.002,CPUs utilized
            0.001813453,S0,1,2,,context-switches,1868028,100.00,1.070,K/sec
            ------
            0.001813453,S0,1,85379,,instructions,1856754,100.00,0.32,insn per cycle
    ====>   0.001813453,,S0,1,,,,,,,1.34,stalled cycles per insn
    
    Above result also has an extra CSV separator after
    the timestamp. Patch addresses extra field separator
    in the beginning of the metric output line.
    
    The counter stats are displayed by function
    "perf_stat__print_shadow_stats" in code
    "util/stat-shadow.c". While printing the stats info
    for "stalled cycles per insn", function "new_line_csv"
    is used as new_line callback.
    
    The new_line_csv function has check for "os->prefix"
    and if prefix is not null, it will be printed along
    with cvs separator.
    Snippet from "new_line_csv":
            if (os->prefix)
                   fprintf(os->fh, "%s%s", os->prefix, config->csv_sep);
    
    Here os->prefix gets printed followed by ","
    which is the cvs separator. The os->prefix is
    used in interval mode option ( -I ), to print
    time stamp on every new line. But prefix is
    already set to contain CSV separator when used
    in interval mode for CSV option.
    
    Reference: Function "static void print_interval"
    Snippet:
            sprintf(prefix, "%6lu.%09lu%s", ts->tv_sec, ts->tv_nsec, config->csv_sep);
    
    Also if prefix is not assigned (if not used with
    -I option), it gets set to empty string.
    Reference: function printout() in util/stat-display.c
    Snippet:
            .prefix = prefix ? prefix : "",
    
    Since prefix already set to contain cvs_sep in interval
    option, patch removes printing config->csv_sep in
    new_line_csv function to avoid printing extra field.
    
    After the patch:
    
            # ./perf stat -x, --per-socket -a -C 1 ls
            S0,1,2.04,msec,cpu-clock,2045202,100.00,1.013,CPUs utilized

    platform/x86: hp_wmi: Fix rfkill causing soft blocked wifi
    
    commit 1598bfa8e1faa932de42e1ee7628a1c4c4263f0a upstream.
    
    After upgrading BIOS to U82 01.02.01 Rev.A, the console is flooded
    strange char "^@" which printed out every second and makes login
    nearly impossible. Also the below messages were shown both in console
    and journal/dmesg every second:
    
    usb 1-3: Device not responding to setup address.
    usb 1-3: device not accepting address 4, error -71
    usb 1-3: device descriptor read/all, error -71
    usb usb1-port3: unable to enumerate USB device
    
    Wifi is soft blocked by checking rfkill. When unblocked manually,
    after few seconds it would be soft blocked again. So I was suspecting
    something triggered rfkill to soft block wifi.  At the end it was
    fixed by removing hp_wmi module.
    
    The root cause is the way hp-wmi driver handles command 1B on
    post-2009 BIOS.  In pre-2009 BIOS, command 1Bh return 0x4 to indicate
    that BIOS no longer controls the power for the wireless devices.

    [ Upstream commit da815582cf4594e96defa1cddb72cd00b1e7aac5 ]
    
    riscv has selected HAVE_DMA_CONTIGUOUS, but doesn't call
    dma_contiguous_reserve().  This calls dma_contiguous_reserve(), which
    enables CMA.

    riscv: fix reserved memory setup
    
    [ Upstream commit 50e63dd8ed92045eb70a72d7ec725488320fb68b ]
    
    Currently, RISC-V sets up reserved memory using the "early" copy of the
    device tree. As a result, when trying to get a reserved memory region
    using of_reserved_mem_lookup(), the pointer to reserved memory regions
    is using the early, pre-virtual-memory address which causes a kernel
    panic when trying to use the buffer's name:
    
     Unable to handle kernel paging request at virtual address 00000000401c31ac

    early_init_fdt_scan_reserved_mem() takes no arguments as it operates on
    initial_boot_params, which is populated by early_init_dt_verify(). On
    RISC-V, early_init_dt_verify() is called twice. Once, directly, in
    setup_arch() if CONFIG_BUILTIN_DTB is not enabled and once indirectly,
    very early in the boot process, by parse_dtb() when it calls
    early_init_dt_scan_nodes().
    
    This first call uses dtb_early_va to set initial_boot_params, which is
    not usable later in the boot process when
    early_init_fdt_scan_reserved_mem() is called. On arm64 for example, the
    corresponding call to early_init_dt_scan_nodes() uses fixmap addresses
    and doesn't suffer the same fate.
    
    Move early_init_fdt_scan_reserved_mem() further along the boot sequence,
    after the direct call to early_init_dt_verify() in setup_arch() so that
    the names use the correct virtual memory addresses. The above supposed
    that CONFIG_BUILTIN_DTB was not set, but should work equally in the case
    where it is - unflatted_and_copy_device_tree() also updates
    initial_boot_params.

    thread_struct's s[12] may contain random kernel memory content, which
    may be finally leaked to userspace. This is a security hole. Fix it
    by clearing the s[12] array in thread_struct when fork.
    
    As for kthread case, it's better to clear the s[12] array as well.

    riscv: Separate memory init from paging init
    
    [ Upstream commit cbd34f4bb37d62d8a027f54205bff07e73340da4 ]
    
    Currently, we perform some memory init functions in paging init. But,
    that will be an issue for NUMA support where DT needs to be flattened
    before numa initialization and memblock_present can only be called
    after numa initialization.
    
    Move memory initialization related functions to a separate function.

    riscv: vdso: fix build with llvm
    
    [ Upstream commit 50f4dd657a0fcf90aa8da8dc2794a8100ff4c37c ]
    
    Even after commit 89fd4a1df829 ("riscv: jump_label: mark arguments as
    const to satisfy asm constraints"), building with CC_OPTIMIZE_FOR_SIZE
    + LLVM=1 can reproduce below build error:

                    ^
    1 error generated.
    
    I think the problem is when "-Os" is passed as CFLAGS, it's removed by
    "CFLAGS_REMOVE_vgettimeofday.o = $(CC_FLAGS_FTRACE) -Os" which is
    introduced in commit e05d57dcb8c7 ("riscv: Fixup __vdso_gettimeofday
    broke dynamic ftrace"), thus no optimization at all for vgettimeofday.c
    arm64 does remove "-Os" as well, but it forces "-O2" after removing
    "-Os".
    
    I compared the generated vgettimeofday.o with "-O2" and "-Os",
    I think no big performance difference. So let's tell the kbuild not
    to remove "-Os" rather than follow arm64 style.
    
    vdso related performance can be improved a lot when building kernel with
    CC_OPTIMIZE_FOR_SIZE after this commit, ("-Os" VS no optimization)

tcp: prohibit TCP_REPAIR_OPTIONS if data was already sent [+ + +]

    tcp: prohibit TCP_REPAIR_OPTIONS if data was already sent
    
    [ Upstream commit 0c175da7b0378445f5ef53904247cfbfb87e0b78 ]
    
    If setsockopt with option name of TCP_REPAIR_OPTIONS and opt_code
    of TCPOPT_SACK_PERM is called to enable sack after data is sent
    and dupacks are received , it will trigger a warning in function
    tcp_verify_left_out() as follows:
    
    ============================================
    WARNING: CPU: 8 PID: 0 at net/ipv4/tcp_input.c:2132
    tcp_timeout_mark_lost+0x154/0x160
    tcp_enter_loss+0x2b/0x290

    run_timer_softirq+0x43/0xb0
    __do_softirq+0xfd/0x373
    __irq_exit_rcu+0xf6/0x140
    
    The warning is caused in the following steps:
    1. a socket named socketA is created
    2. socketA enters repair mode without build a connection
    3. socketA calls connect() and its state is changed to TCP_ESTABLISHED
       directly
    4. socketA leaves repair mode
    5. socketA calls sendmsg() to send data, packets_out and sack_outs(dup
       ack receives) increase
    6. socketA enters repair mode again
    7. socketA calls setsockopt with TCPOPT_SACK_PERM to enable sack
    8. retransmit timer expires, it calls tcp_timeout_mark_lost(), lost_out
       increases
    9. sack_outs + lost_out > packets_out triggers since lost_out and
       sack_outs increase repeatly
    
    In function tcp_timeout_mark_lost(), tp->sacked_out will be cleared if
    Step7 not happen and the warning will not be triggered. As suggested by
    Denis and Eric, TCP_REPAIR_OPTIONS should be prohibited if data was
    already sent.
    
    socket-tcp tests in CRIU has been tested as follows:
    $ sudo ./test/zdtm.py run -t zdtm/static/socket-tcp*  --keep-going \
           --ignore-taint
    
    socket-tcp* represent all socket-tcp tests in test/zdtm/static/.

    Fix this by changing the memory size allocated for copy_name from
    UDF_NAME_LEN(254) to UDF_NAME_LEN_CS0(255), because the total length
    (lfi) of subsequent memcpy can be up to 255.

vmlinux.lds.h: Fix placement of '.data..decrypted' section [+ + +]
Author: Nathan Chancellor <[email protected]>

    vmlinux.lds.h: Fix placement of '.data..decrypted' section
    
    commit 000f8870a47bdc36730357883b6aef42bced91ee upstream.
    
    Commit d4c639990036 ("vmlinux.lds.h: Avoid orphan section with !SMP")
    fixed an orphan section warning by adding the '.data..decrypted' section
    to the linker script under the PERCPU_DECRYPTED_SECTION define but that
    placement introduced a panic with !SMP, as the percpu sections are not
    instantiated with that configuration so attempting to access variables
    defined with DEFINE_PER_CPU_DECRYPTED() will result in a page fault.
    
    Move the '.data..decrypted' section to the DATA_MAIN define so that the
    variables in it are properly instantiated at boot time with
    CONFIG_SMP=n.

wifi: cfg80211: fix memory leak in query_regdb_file() [+ + +]
Author: Arend van Spriel <[email protected]>
Date:   Thu Oct 20 13:40:40 2022 +0200

    wifi: cfg80211: fix memory leak in query_regdb_file()
    
    [ Upstream commit 57b962e627ec0ae53d4d16d7bd1033e27e67677a ]
    
    In the function query_regdb_file() the alpha2 parameter is duplicated
    using kmemdup() and subsequently freed in regdb_fw_cb(). However,
    request_firmware_nowait() can fail without calling regdb_fw_cb() and
    thus leak memory.

    All we're going to do with this pointer is assign it to
    another __rcu pointer, but sparse can't see that, so
    use rcu_access_pointer() to silence the warning here.

x86/cpu: Restore AMD's DE_CFG MSR after resume [+ + +]

    x86/cpu: Restore AMD's DE_CFG MSR after resume
    
    commit 2632daebafd04746b4b96c2f26a6021bc38f6209 upstream.
    
    DE_CFG contains the LFENCE serializing bit, restore it on resume too.
    This is relevant to older families due to the way how they do S3.
    
    Unify and correct naming while at it.
