      iio: adc: ti-ads1015: fix incorrect data rate setting update · cc06f5a9
      Akinobu Mita authored
      commit 0d106b74 upstream.
      
      The ti-ads1015 driver has eight iio voltage channels and each iio channel
      can hold own sampling frequency information.
      
      The ADS1015 device only have a single config register which contains an
      input multiplexer selection, PGA and data rate settings.  So the driver
      should load the correct settings when the input multiplexer selection is
      changed.
      
      However, regardless of which channlel is currently selected, changing any
      iio channel's sampling frequency information immediately overwrites the
      current data rate setting in the config register.
      
      It breaks the current data rate setting if the different channel's sampling
      frequency information is changed because the data rate setting is not
      reloaded when the input multiplexer is switched.
      
      This removes the unexpected config register update and correctly load the
      data rate setting before getting adc result.

      staging: ccree: save ciphertext for CTS IV · 2d94a1e8
      Gilad Ben-Yossef authored
      commit 737aed94 upstream.
      
      The crypto API requires saving the last blocks of ciphertext
      in req->info for use as IV for CTS mode. The ccree driver
      was not doing this. This patch fixes that.
      
      The bug was manifested with cts(cbc(aes)) mode in tcrypt tests.

      staging/rts5208: fix incorrect shift to extract upper nybble · a55273d7
      Colin Ian King authored
      commit 34ff1bf4 upstream.
      
      The mask of sns_key_info1 suggests the upper nybble is being extracted
      however the following shift of 8 bits is too large and always results in
      0.  Fix this by shifting only by 4 bits to correctly get the upper nybble.

      Investigation using kgdb() found that the wait queue that was passed
      into wake_up() had been freed (it was filled with slub_debug poison).
      
      I analyzed and instrumented the code and reproduced.  My current
      belief is that this is happening:
      
      1. async_completed() is called (from IRQ).  Moves "as" onto the
         completed list.
      2. On another CPU, proc_reapurbnonblock_compat() calls
         async_getcompleted().  Blocks on spinlock.
      3. async_completed() releases the lock; keeps running; gets blocked
         midway through wake_up().
      4. proc_reapurbnonblock_compat() => async_getcompleted() gets the
         lock; removes "as" from completed list and frees it.
      5. usbdev_release() is called.  Frees "ps".
      6. async_completed() finally continues running wake_up().  ...but
         wake_up() has a pointer to the freed "ps".
      
      The instrumentation that led me to believe this was based on adding
      some trace_printk() calls in a select few functions and then using
      kdb's "ftdump" at crash time.  The trace follows (NOTE: in the trace
      below I cheated a little bit and added a udelay(1000) in
      async_completed() after releasing the spinlock because I wanted it to
      trigger quicker):
      
      <...>-2104   0d.h2 13759034us!: async_completed at start: as=ffffffc0cc638200
      mtpd-2055    3.... 13759356us : async_getcompleted before spin_lock_irqsave

      mtpd-2055    3.... 13759371us+: proc_reapurbnonblock_compat: free_async(ffffffc0cc638200)
      mtpd-2055    3.... 13759422us+: async_getcompleted before spin_lock_irqsave
      mtpd-2055    3.... 13759479us : usbdev_release at start: ps=ffffffc0cc042080
      mtpd-2055    3.... 13759487us : async_getcompleted before spin_lock_irqsave
      mtpd-2055    3.... 13759497us!: usbdev_release after kfree(ps): ps=ffffffc0cc042080
      <...>-2104   0d.h2 13760294us : async_completed before wake_up(): as=ffffffc0cc638200
      
      To fix this problem we can just move the wake_up() under the ps->lock.
      There should be no issues there that I'm aware of.

      ANDROID: binder: add padding to binder_fd_array_object. · df338972
      Martijn Coenen authored
      commit 5cdcf4c6 upstream.
      
      binder_fd_array_object starts with a 4-byte header,
      followed by a few fields that are 8 bytes when
      ANDROID_BINDER_IPC_32BIT=N.
      
      This can cause alignment issues in a 64-bit kernel
      with a 32-bit userspace, as on x86_32 an 8-byte primitive
      may be aligned to a 4-byte address. Pad with a __u32
      to fix this.

      USB: musb: fix external abort on suspend · 26be1058
      Johan Hovold authored
      commit 082df8be upstream.
      
      Make sure that the controller is runtime resumed when system suspending
      to avoid an external abort when accessing the interrupt registers:
      
        Unhandled fault: external abort on non-linefetch (0x1008) at 0xd025840a
        ...
        [<c05481a4>] (musb_default_readb) from [<c0545abc>] (musb_disable_interrupts+0x84/0xa8)
        [<c0545abc>] (musb_disable_interrupts) from [<c0546b08>] (musb_suspend+0x38/0xb8)
        [<c0546b08>] (musb_suspend) from [<c04a57f8>] (platform_pm_suspend+0x3c/0x64)
      
      This is easily reproduced on a BBB by enabling the peripheral port only
      (as the host port may enable the shared clock) and keeping it
      disconnected so that the controller is runtime suspended. (Well, you
      would also need to the not-yet-merged am33xx-suspend patches by Dave
      Gerlach to be able to suspend the BBB.)
      
      This is a regression that was introduced by commit 1c4d0b4e ("usb:
      musb: Remove pm_runtime_set_irq_safe") which allowed the parent glue
      device to runtime suspend and thereby exposed a couple of older issues:
      
      Register accesses without explicitly making sure the controller is
      runtime resumed during suspend was first introduced by commit c338412b
      ("usb: musb: unconditionally save and restore the context on suspend")
      in 3.14.
      
      Commit a1fc1920 ("usb: musb: core: make sure musb is in RPM_ACTIVE on
      resume") later started setting the RPM status to active during resume,
      and this was also implicitly relying on the parent always being active.
      Since commit 71723f95 ("PM / runtime: print error when activating a
      child to unactive parent") this now also results in the following
      warning:
      
        musb-hdrc musb-hdrc.0: runtime PM trying to activate child device
          musb-hdrc.0 but parent (47401400.usb) is not active
      
      This patch has been verified on 4.13-rc2, 4.12 and 4.9 using a BBB
      (the dsps glue would always be active also in 4.8).
      
      Fixes: c338412b ("usb: musb: unconditionally save and restore the context on suspend")
      Fixes: a1fc1920 ("usb: musb: core: make sure musb is in RPM_ACTIVE on resume")

      epoll: fix race between ep_poll_callback(POLLFREE) and ep_free()/ep_remove() · 138e4ad6
      Oleg Nesterov authored
      The race was introduced by me in commit 971316f0 ("epoll:
      ep_unregister_pollwait() can use the freed pwq->whead").  I did not
      realize that nothing can protect eventpoll after ep_poll_callback() sets
      ->whead = NULL, only whead->lock can save us from the race with
      ep_free() or ep_remove().
      
      Move ->whead = NULL to the end of ep_poll_callback() and add the
      necessary barriers.
      
      TODO: cleanup the ewake/EPOLLEXCLUSIVE logic, it was confusing even
      before this patch.
      
      Hopefully this explains use-after-free reported by syzcaller:

      we preserve the secpath for the whole skb lifecycle, but we also
      end up leaking a reference to it.
      
      We must clear the head state on skb reception, if secpath is

      bridge: switchdev: Clear forward mark when transmitting packet · 79e99bdd
      Ido Schimmel authored
      Commit 6bc506b4 ("bridge: switchdev: Add forward mark support for
      stacked devices") added the 'offload_fwd_mark' bit to the skb in order
      to allow drivers to indicate to the bridge driver that they already
      forwarded the packet in L2.
      
      In case the bit is set, before transmitting the packet from each port,
      the port's mark is compared with the mark stored in the skb's control
      block. If both marks are equal, we know the packet arrived from a switch
      device that already forwarded the packet and it's not re-transmitted.
      
      However, if the packet is transmitted from the bridge device itself
      (e.g., br0), we should clear the 'offload_fwd_mark' bit as the mark
      stored in the skb's control block isn't valid.
      
      This scenario can happen in rare cases where a packet was trapped during
      L3 forwarding and forwarded by the kernel to a bridge device.

      mlxsw: spectrum: Forbid linking to devices that have uppers · 25cc72a3
      Ido Schimmel authored
      The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the
      device in case a port is enslaved to a master netdev such as bridge or
      bond.
      
      Since the driver ignores events unrelated to its ports and their
      uppers, it's possible to engineer situations in which the device's data
      path differs from the kernel's.
      
      One example to such a situation is when a port is enslaved to a bond
      that is already enslaved to a bridge. When the bond was enslaved the
      driver ignored the event - as the bond wasn't one of its uppers - and
      therefore a bridge port instance isn't created in the device.
      
      Until such configurations are supported forbid them by checking that the
      upper device doesn't have uppers of its own.

        This is in a weird way fixed by commit c7ab0d2f ("mm: convert
        try_to_unmap_one() to use page_vma_mapped_walk()") which moved the
        callback under the page table lock. Which also broke several existing
        user of the mmu_notifier API that assumed they could sleep inside this
        callback.
      
        The second pitfall was invalidate_page being the only callback not
        taking a range of address in respect to invalidation but was giving an
        address and a page. Lot of the callback implementer assumed this could
        never be THP and thus failed to invalidate the appropriate range for
        THP pages.
      
        By killing this callback we unify the mmu_notifier callback API to
        always take a virtual address range as input.
      
        There is now two clear API (I am not mentioning the youngess API which
        is seldomly used):
      
         - invalidate_range_start()/end() callback (which allow you to sleep)
      
         - invalidate_range() where you can not sleep but happen right after
           page table update under page table lock
      
        Note that a lot of existing user feels broken in respect to
        range_start/ range_end. Many user only have range_start() callback but
        there is nothing preventing them to undo what was invalidated in their
        range_start() callback after it returns but before any CPU page table
        update take place.
      
        The code pattern use in kvm or umem odp is an example on how to
        properly avoid such race. In a nutshell use some kind of sequence
        number and active range invalidation counter to block anything that
        might undo what the range_start() callback did.
      
        If you do not care about keeping fully in sync with CPU page table (ie
        you can live with CPU page table pointing to new different page for a
        given virtual address) then you can take a reference on the pages
        inside the range_start callback and drop it in range_end or when your
        driver is done with those pages.
      
        Last alternative is to use invalidate_range() if you can do
        invalidation without sleeping as invalidate_range() callback happens
        under the CPU page table spinlock right after the page table is
        updated.
      
        The first two patches convert existing mmu_notifier_invalidate_page()
        calls to mmu_notifier_invalidate_range() and bracket those call with
        call to mmu_notifier_invalidate_range_start()/end().
      
        The next ten patches remove existing invalidate_page() callback as it
        can no longer happen.
      
        Finally the last page remove the invalidate_page() callback completely
        so it can RIP.
      
        Changes since v1:
         - remove more dead code in kvm (no testing impact)
         - more accurate end address computation (patch 2) in page_mkclean_one
           and try_to_unmap_one
         - added tested-by/reviewed-by gotten so far"

      jfs should use MAX_LFS_FILESIZE when calculating s_maxbytes · c227390c
      Dave Kleikamp authored
      jfs had previously avoided the use of MAX_LFS_FILESIZE because it hadn't
      accounted for the whole 32-bit index range on 32-bit systems.  That has
      been fixed by commit 0cc3b0ec ("Clarify (and fix) MAX_LFS_FILESIZE
      macros"), so we can simplify the code now.

      scripts/dtc: fix '%zx' warning · e6618692
      Russell King authored
      dtc uses an incorrect format specifier for printing a uint64_t value.
      uint64_t may be either 'unsigned long' or 'unsigned long long' depending
      on the host architecture.
      
      Fix this by using %llx and casting to unsigned long long, which ensures
      that we always have a wide enough variable to print 64 bits of hex.
