      HID: prodikeys: Fix general protection fault during probe · 98375b86

      The syzbot fuzzer provoked a general protection fault in the
      hid-prodikeys driver:

      The problem is caused by the fact that pcmidi_get_output_report() will
      return an error if the HID device doesn't provide the right sort of
      output report, but pcmidi_set_operational() doesn't bother to check
      the return code and assumes the function call always succeeds.
      
      This patch adds the missing check and aborts the probe operation if
      necessary.

      HID: sony: Fix memory corruption issue on cleanup. · 2bcdacb7
      Roderick Colenbrander authored
      The sony driver is not properly cleaning up from potential failures in
      sony_input_configured. Currently it calls hid_hw_stop, while hid_connect
      is still running. This is not a good idea, instead hid_hw_stop should
      be moved to sony_probe. Similar changes were recently made to Logitech
      drivers, which were also doing improper cleanup.

      HID: logitech-dj: Fix crash when initial logi_dj_recv_query_paired_devices fails · 8ccff284
      Hans de Goede authored
      Before this commit dj_probe would exit with an error if the initial
      logi_dj_recv_query_paired_devices fails. The initial call may fail
      when the receiver is connected through a kvm and the focus is away.
      
      When the call fails this causes 2 problems:
      
      1) dj_probe calls logi_dj_recv_query_paired_devices after calling
      hid_device_io_start() so a HID report may have been received in between
      and our delayedwork_callback may be running. It seems that the initial
      logi_dj_recv_query_paired_devices failure happening with some KVMs triggers
      this exact scenario, causing the work-queue to run on free-ed memory,
      leading to:
      
       BUG: unable to handle page fault for address: 0000000000001e88

      2) Even if we were to fix 1. by making sure the work is stopped before
      failing probe, failing probe is the wrong thing to do, we have
      logi_dj_recv_queue_unknown_work to deal with the initial
      logi_dj_recv_query_paired_devices failure.
      
      Rather then error-ing out of the probe, causing the receiver to not work at
      all we should rely on this, so that the attached devices will get properly
      enumerated once the KVM focus is switched back.

      HID: multitouch: add support for the Smart Tech panel · 69ecd44d
      Benjamin Tissoires authored
      This panel is not very friendly to us:
      it exposes multiple multitouch collections, some of them being of
      logical application stylus.
      
      Usually, a device has only one report per application, and that is
      what I assumed in commit 8dfe14b3 ("HID: multitouch: ditch mt_report_id")
      
      To avoid breaking all working device, add a new class and a new quirk
      for that situation.

      HID: multitouch: do not filter mice nodes · c23e2043
      Benjamin Tissoires authored
      It was a good idea at the time to not create a mouse node for the
      multitouch touchscreens, but:
      - touchscreens following the Win 8 protocol should not have this
        disturbing mouse node anymore, or if they have, it should be
        used for something else (like a joystick attached to the screen)
      - touchpads have it, and they should not use it unless there is a bug,
        but when the laptop has a trackstick, the data are reported through this
        mouse node.
      
      So instead of whitelisting all of the devices that have a need for the
      mouse node, just export it.
      hid-input.c will append a suffix to it ('Mouse'), so users will eventually
      see if something goes wrong.

      This is a common pattern in the HID drivers to reset the drvdata. Some

      But, this is actually already handled by driver core, so there is no need

      The two problems have the same cause: hidraw_ioctl() fails to test
      whether the device has been removed.  This patch adds the missing test.

      Pull kernel thread signal handling fix from Eric Biederman:
       "I overlooked the fact that kernel threads are created with all signals
        set to SIG_IGN, and accidentally caused a regression in cifs and drbd
        when replacing force_sig with send_sig.
      
        This is my fix for that regression. I add a new function
        allow_kernel_signal which allows kernel threads to receive signals
        sent from the kernel, but continues to ignore all signals sent from
        userspace. This ensures the user space interface for cifs and drbd
        remain the same.
      
        These kernel threads depend on blocking networking calls which block
        until something is received or a signal is pending. Making receiving
        of signals somewhat necessary for these kernel threads.
      
        Perhaps someday we can cleanup those interfaces and remove
        allow_kernel_signal. If not allow_kernel_signal is pretty trivial and
        clearly documents what is going on so I don't think we will mind
        carrying it"

      keys: Fix description size · 555df336
      David Howells authored
      The maximum key description size is 4095.  Commit f771fde8 ("keys:
      Simplify key description management") inadvertantly reduced that to 255
      and made sizes between 256 and 4095 work weirdly, and any size whereby
      size & 255 == 0 would cause an assertion in __key_link_begin() at the
      following line:
      
      	BUG_ON(index_key->desc_len == 0);
      
      This can be fixed by simply increasing the size of desc_len in struct
      keyring_index_key to a u16.
      
      Note the argument length test in keyutils only checked empty
      descriptions and descriptions with a size around the limit (ie.  4095)
      and not for all the values in between, so it missed this.  This has been
      addressed and
      
      	https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/keyutils.git/commit/?id=066bf56807c26cd3045a25f355b34c1d8a20a5aa
      
      now exhaustively tests all possible lengths of type, description and
      payload and then some.
      
      The assertion failure looks something like:
      
       kernel BUG at security/keys/keyring.c:1245!

      HID: cp2112: prevent sleeping function called from invalid context · 2d05dba2
      Benjamin Tissoires authored
      When calling request_threaded_irq() with a CP2112, the function
      cp2112_gpio_irq_startup() is called in a IRQ context.
      
      Therefore we can not sleep, and we can not call
      cp2112_gpio_direction_input() there.
      
      Move the call to cp2112_gpio_direction_input() earlier to have a working
      driver.
