      driver core: Don't probe devices after bus_type.match() probe deferral · 742e222d
      Isaac J. Manjarres authored
      commit 25e9fbf0 upstream.
      
      Both __device_attach_driver() and __driver_attach() check the return
      code of the bus_type.match() function to see if the device needs to be
      added to the deferred probe list. After adding the device to the list,
      the logic attempts to bind the device to the driver anyway, as if the
      device had matched with the driver, which is not correct.
      
      If __device_attach_driver() detects that the device in question is not
      ready to match with a driver on the bus, then it doesn't make sense for
      the device to attempt to bind with the current driver or continue
      attempting to match with any of the other drivers on the bus. So, update
      the logic in __device_attach_driver() to reflect this.
      
      If __driver_attach() detects that a driver tried to match with a device
      that is not ready to match yet, then the driver should not attempt to bind
      with the device. However, the driver can still attempt to match and bind
      with other devices on the bus, as drivers can be bound to multiple
      devices. So, update the logic in __driver_attach() to reflect this.

      usb: gadget: mass_storage: Fix cdrom data transfers on MAC-OS · 6202637f
      Krishna Kurapati authored
      commit 9d4dc16e upstream.
      
      During cdrom emulation, the response to read_toc command must contain
      the cdrom address as the number of sectors (2048 byte sized blocks)
      represented either as an absolute value (when MSF bit is '0') or in
      terms of PMin/PSec/PFrame (when MSF bit is set to '1'). Incase of
      cdrom, the fsg_lun_open call sets the sector size to 2048 bytes.
      
      When MAC OS sends a read_toc request with MSF set to '1', the
      store_cdrom_address assumes that the address being provided is the
      LUN size represented in 512 byte sized blocks instead of 2048. It
      tries to modify the address further to convert it to 2048 byte sized
      blocks and store it in MSF format. This results in data transfer
      failures as the cdrom address being provided in the read_toc response
      is incorrect.

      This turned out not to be an error in usb-storage but rather a nested
      device reset attempt.  That is, as the rtl8712 driver was being
      unbound from a composite device in preparation for an unrelated USB
      reset (that driver does not have pre_reset or post_reset callbacks),
      its ->remove routine called usb_reset_device() -- thus nesting one
      reset call within another.
      
      Performing a reset as part of disconnect processing is a questionable
      practice at best.  However, the bug report points out that the USB
      core does not have any protection against nested resets.  Adding a
      reset_in_progress flag and testing it will prevent such errors in the
      future.

      s390: fix nospec table alignments · b0d4993c
      Josh Poimboeuf authored
      commit c9305b6c upstream.
      
      Add proper alignment for .nospec_call_table and .nospec_return_table in
      vmlinux.
      
      [hca@linux.ibm.com]: The problem with the missing alignment of the nospec
      tables exist since a long time, however only since commit e6ed91fd
      ("s390/alternatives: remove padding generation code") and with
      CONFIG_RELOCATABLE=n the kernel may also crash at boot time.
      
      The above named commit reduced the size of struct alt_instr by one byte,
      so its new size is 11 bytes. Therefore depending on the number of cpu
      alternatives the size of the __alt_instructions array maybe odd, which
      again also causes that the addresses of the nospec tables will be odd.
      
      If the address of __nospec_call_start is odd and the kernel is compiled
      With CONFIG_RELOCATABLE=n the compiler may generate code that loads the
      address of __nospec_call_start with a 'larl' instruction.
      
      This will generate incorrect code since the 'larl' instruction only works
      with even addresses. In result the members of the nospec tables will be
      accessed with an off-by-one offset, which subsequently may lead to
      addressing exceptions within __nospec_revert().

      s390/hugetlb: fix prepare_hugepage_range() check for 2 GB hugepages · 0361d50e
      Gerald Schaefer authored
      commit 7c8d42fd upstream.
      
      The alignment check in prepare_hugepage_range() is wrong for 2 GB
      hugepages, it only checks for 1 MB hugepage alignment.
      
      This can result in kernel crash in __unmap_hugepage_range() at the
      BUG_ON(start & ~huge_page_mask(h)) alignment check, for mappings
      created with MAP_FIXED at unaligned address.
      
      Fix this by correctly handling multiple hugepage sizes, similar to the
      generic version of prepare_hugepage_range().

      Since 1599069a ("phy: core: Warn when phy_power_on is called before

      is: phy phy-fe03e000.phy.2: phy_power_on was called before phy_init
      So change the order of the two calls. The same change has to be done
      to the order of phy_exit() and phy_power_off().

      usb: typec: altmodes/displayport: correct pin assignment for UFP receptacles · 95791d51
      Pablo Sun authored
      commit c1e5c2f0 upstream.
      
      Fix incorrect pin assignment values when connecting to a monitor with
      Type-C receptacle instead of a plug.
      
      According to specification, an UFP_D receptacle's pin assignment
      should came from the UFP_D pin assignments field (bit 23:16), while
      an UFP_D plug's assignments are described in the DFP_D pin assignments
      (bit 15:8) during Mode Discovery.
      
      For example the LG 27 UL850-W is a monitor with Type-C receptacle.
      The monitor responds to MODE DISCOVERY command with following
      DisplayPort Capability flag:
      
              dp->alt->vdo=0x140045
      
      The existing logic only take cares of UPF_D plug case,
      and would take the bit 15:8 for this 0x140045 case.
      
      This results in an non-existing pin assignment 0x0 in
      dp_altmode_configure.
      
      To fix this problem a new set of macros are introduced

      xhci: Add grace period after xHC start to prevent premature runtime suspend. · 5a603f4c
      Mathias Nyman authored
      commit 33e32158
      
       upstream.
      
      After xHC controller is started, either in probe or resume, it can take
      a while before any of the connected usb devices are visible to the roothub
      due to link training.
      
      It's possible xhci driver loads, sees no acivity and suspends the host
      before the USB device is visible.
      
      In one testcase with a hotplugged xHC controller the host finally detected
      the connected USB device and generated a wake 500ms after host initial
      start.
      
      If hosts didn't suspend the device duringe training it probablty wouldn't
      take up to 500ms to detect it, but looking at specs reveal USB3 link
      training has a couple long timeout values, such as 120ms
      RxDetectQuietTimeout, and 360ms PollingLFPSTimeout.
      
      So Add a 500ms grace period that keeps polling the roothub for 500ms after
      start, preventing runtime suspend until USB devices are detected.

      The reason for the warning is clear enough; the driver sends an

      More importantly, the whole situation can be avoided and the driver
      simplified by converting it over to the relatively new
      usb_control_msg_recv() and usb_control_msg_send() routines.  That's
      what this fix does.

      xen-blkfront: Advertise feature-persistent as user requested · f210912d
      SeongJae Park authored
      commit 9f5e0fe5 upstream.
      
      The advertisement of the persistent grants feature (writing
      'feature-persistent' to xenbus) should mean not the decision for using
      the feature but only the availability of the feature.  However, commit
      74a85247 ("xen-blkfront: add a parameter for disabling of persistent
      grants") made a field of blkfront, which was a place for saving only the
      negotiation result, to be used for yet another purpose: caching of the
      'feature_persistent' parameter value.  As a result, the advertisement,
      which should follow only the parameter value, becomes inconsistent.
      
      This commit fixes the misuse of the semantic by making blkfront saves
      the parameter value in a separate place and advertises the support based
      on only the saved value.

      mm: pagewalk: Fix race between unmap and page walker · 47a73e5e
      Steven Price authored
      [ Upstream commit 8782fb61 ]
      
      The mmap lock protects the page walker from changes to the page tables
      during the walk.  However a read lock is insufficient to protect those
      areas which don't have a VMA as munmap() detaches the VMAs before
      downgrading to a read lock and actually tearing down PTEs/page tables.
      
      For users of walk_page_range() the solution is to simply call pte_hole()
      immediately without checking the actual page tables when a VMA is not
      present. We now never call __walk_page_range() without a valid vma.
      
      For walk_page_range_novma() the locking requirements are tightened to
      require the mmap write lock to be taken, and then walking the pgd
      directly with 'no_vma' set.
      
      This in turn means that all page walkers either have a valid vma, or
      it's that special 'novma' case for page table debugging.  As a result,
      all the odd '(!walk->vma && !walk->no_vma)' tests can be removed.

      KVM: x86: Mask off unsupported and unknown bits of IA32_ARCH_CAPABILITIES · eb0c614c
      Jim Mattson authored
      [ Upstream commit 0204750b ]
      
      KVM should not claim to virtualize unknown IA32_ARCH_CAPABILITIES
      bits. When kvm_get_arch_capabilities() was originally written, there
      were only a few bits defined in this MSR, and KVM could virtualize all
      of them. However, over the years, several bits have been defined that
      KVM cannot just blindly pass through to the guest without additional
      work (such as virtualizing an MSR promised by the
      IA32_ARCH_CAPABILITES feature bit).
      
      Define a mask of supported IA32_ARCH_CAPABILITIES bits, and mask off
      any other bits that are set in the hardware MSR.

      gpio: pca953x: Add mutex_lock for regcache sync in PM · 7efcbac5
      Haibo Chen authored
      [ Upstream commit 518e26f1 ]
      
      The regcache sync will set the cache_bypass = true, at that
      time, when there is regmap write operation, it will bypass
      the regmap cache, then the regcache sync will write back the
      value from cache to register, which is not as our expectation.
      
      Though regmap already use its internal lock to avoid such issue,
      but this driver force disable the regmap internal lock in its
      regmap config: disable_locking = true
      
      To avoid this issue, use the driver's own lock to do the protect
      in system PM.

      hwmon: (gpio-fan) Fix array out of bounds access · 517dba79
      Armin Wolf authored
      [ Upstream commit f233d2be ]
      
      The driver does not check if the cooling state passed to
      gpio_fan_set_cur_state() exceeds the maximum cooling state as
      stored in fan_data->num_speeds. Since the cooling state is later
      used as an array index in set_fan_speed(), an array out of bounds
      access can occur.
      This can be exploited by setting the state of the thermal cooling device
      to arbitrary values, causing for example a kernel oops when unavailable
      memory is accessed this way.
      
      Example kernel oops:

      The while loop in raspberrypi_discover_clocks() relies on the assumption
      that the id of the last clock element is zero. Because this data comes
      from the Videocore firmware and it doesn't guarantuee such a behavior
      this could lead to out-of-bounds access. So fix this by providing
      a sentinel element.

      [ Upstream commit 35b0fac8 ]
      
      In the previous commits that added CLK_OPS_PARENT_ENABLE, support for
      this flag was only added to rate change operations (rate setting and
      reparent) and disabling unused subtree. It was not added to the
      clock gate related operations. Any hardware driver that needs it for
      these operations will either see bogus results, or worse, hang.
      
      This has been seen on MT8192 and MT8195, where the imp_ii2_* clk
      drivers set this, but dumping debugfs clk_summary would cause it
      to hang.

      binder: fix UAF of ref->proc caused by race condition · 9629f2df
      Carlos Llamas authored
      commit a0e44c64
      
       upstream.
      
      A transaction of type BINDER_TYPE_WEAK_HANDLE can fail to increment the
      reference for a node. In this case, the target proc normally releases
      the failed reference upon close as expected. However, if the target is
      dying in parallel the call will race with binder_deferred_release(), so
      the target could have released all of its references by now leaving the
      cleanup of the new failed reference unhandled.
      
      The transaction then ends and the target proc gets released making the
      ref->proc now a dangling pointer. Later on, ref->node is closed and we
      attempt to take spin_lock(&ref->proc->inner_lock), which leads to the
      use-after-free bug reported below. Let's fix this by cleaning up the
      failed reference on the spot instead of relying on the target to do so.

      misc: fastrpc: fix memory corruption on open · 5cf2a57c
      Johan Hovold authored
      commit d245f43a upstream.
      
      The probe session-duplication overflow check incremented the session
      count also when there were no more available sessions so that memory
      beyond the fixed-size slab-allocated session array could be corrupted in
      fastrpc_session_alloc() on open().

      iio: ad7292: Prevent regulator double disable · 89aa4434
      Matti Vaittinen authored
      commit 22b42776 upstream.
      
      The ad7292 tries to add an devm_action for disabling a regulator at
      device detach using devm_add_action_or_reset(). The
      devm_add_action_or_reset() does call the release function should adding
      action fail. The driver inspects the value returned by
      devm_add_action_or_reset() and manually calls regulator_disable() if
      adding the action has failed. This leads to double disable and messes
      the enable count for regulator.
      
      Do not manually call disable if devm_add_action_or_reset() fails.

      Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flag · b271090e
      Tetsuo Handa authored
      commit 98e01215 upstream.
      
      syzbot is reporting hung task at __input_unregister_device() [1], for
      iforce_close() waiting at wait_event_interruptible() with dev->mutex held
      is blocking input_disconnect_device() from __input_unregister_device().
      
      It seems that the cause is simply that commit c2b27ef6
      
       ("Input:
      iforce - wait for command completion when closing the device") forgot to
      call wake_up() after clear_bit().
      
      Fix this problem by introducing a helper that calls clear_bit() followed
      by wake_up_all().

      tty: serial: lpuart: disable flow control while waiting for the transmit engine to complete · b202400c
      Sherry Sun authored
      commit d5a2e083 upstream.
      
      When the user initializes the uart port, and waits for the transmit
      engine to complete in lpuart32_set_termios(), if the UART TX fifo has
      dirty data and the UARTMODIR enable the flow control, the TX fifo may
      never be empty. So here we should disable the flow control first to make
      sure the transmit engin can complete.
