      HID: Allow drivers to be their own listener · 4bc19f62
      David Herrmann 提交于
      hid-picolcd and hid-wiimote do not allow any of hidinput, hiddev or hidraw
      to claim the device but still want to remain on the bus. Hence, if a
      driver uses the raw_event callback but no other listener claimed the
      device, we still leave it on the bus as the driver handles everything by
      itself. It thus becomes its own listener.
      
      Under some circumstances (eg., hidinput_connect() fails and raw_event set)
      a device may be left on the bus even though it requires external
      listeners. But then if hidinput_connect() fails there are bigger issues
      than a device that is left unhandled. So we can safely use this heuristic
      to avoid adding another flag for special devices like hid-picolcd and
      hid-wiimote.
      
      This also removes the ugly hack from hid-picolcd as this is no longer
      required.

      HID: usbhid: fix error paths in suspend · eb055fd0
      Alan Stern 提交于
      This patch (as1597) fixes some of the error paths in usbhid's suspend
      routine.  The driver was not careful to restart everything that might
      have been stopped, in cases where a suspend failed.
      
      For example, once the HID_SUSPENDED flag is set, an output report
      submission would not restart the corresponding URB queue.  If a
      suspend fails, it's therefore necessary to check whether the queues
      need to be restarted.

      HID: usbhid: check for suspend or reset before restarting · d4150c8f
      Alan Stern 提交于
      This patch (as1596) improves the queue-restart logic in usbhid by
      checking to see if the device is suspended or a reset is about to
      occur.  There's no point submitting an URB if either of those is
      true.

      HID: usbhid: replace HID_REPORTED_IDLE with HID_SUSPENDED · f2b5264d
      Alan Stern 提交于
      This patch (as1595) improves the usbhid driver by using the
      HID_SUSPENDED bitflag to indicate that the device is suspended rather
      than using HID_REPORTED_IDLE, which the patch removes.
      
      Since HID_SUSPENDED was not being used for anything, and since the
      name "HID_REPORTED_IDLE" doesn't convey much meaning, the end result
      is easier to read and understand.

      HID: usbhid: inline some simple routines · 93101af3
      Alan Stern 提交于
      This patch (as1594) simplifies the usbhid driver by inlining a couple
      of routines.  As a result of an earlier patch, irq_out_pump_restart()
      and ctrl_pump_restart() are each used in only one place.  Since they
      don't really do what their names say, and since they each involve only
      about two lines of actual code, there's no reason to keep them as
      separate functions.

      HID: usbhid: fix autosuspend calls · 01a7c984
      Alan Stern 提交于
      This patch (as1593) fixes some logic errors in the usbhid driver
      relating to runtime PM.  The driver does not balance its calls to
      usb_autopm_get_interface_async() and usb_autopm_put_interface_async().
      
      For example, when the control queue is restarted the driver does a
      _get.  But the resume won't happen immediately, so the driver leaves
      the queue stopped.  When the resume does occur, the queue is restarted
      and a second _get occurs, with no balancing _put.
      
      The patch fixes the problem by rearranging the logic for restarting
      the queues.  All the _get/_put calls and bitflag settings in
      __usbhid_submit_report() are moved into the queue-restart routines.  A
      balancing _put call is added for the case where the queue is still
      suspended.  A call to irq_out_pump_restart(), which doesn't take all
      the right actions for restarting the irq-OUT queue, is replaced by a
      call to usbhid_restart_out_queue(), which does.  Similarly for
      ctrl_pump_restart().
      
      Finally, new code is added to prevent an autosuspend from happening
      every time an URB is cancelled, and the comments explaining what
      happens when an URB needs to be cancelled are expanded and clarified.

      HID: usbhid: fix use-after-free bug · 668160e5
      Alan Stern 提交于
      This patch (as1592) fixes an obscure problem in the usbhid driver.
      Under some circumstances, a control or interrupt-OUT URB can be
      submitted twice.  This will happen if the first submission fails; the
      queue pointers aren't updated, so the next time the queue is restarted
      the same URB will be submitted again.
      
      The problem is that raw_report gets deallocated during the first
      submission.  The second submission will then dereference and try to
      free an already-freed region of memory.  The patch fixes the problem
      by setting raw_report to NULL when it is deallocated and checking for
      NULL before dereferencing it.

      Make wait_for_device_probe() also do scsi_complete_async_scans() · eea03c20
      Linus Torvalds 提交于
      Commit a7a20d10 ("sd: limit the scope of the async probe domain")
      make the SCSI device probing run device discovery in it's own async
      domain.
      
      However, as a result, the partition detection was no longer synchronized
      by async_synchronize_full() (which, despite the name, only synchronizes
      the global async space, not all of them).  Which in turn meant that
      "wait_for_device_probe()" would not wait for the SCSI partitions to be
      parsed.
      
      And "wait_for_device_probe()" was what the boot time init code relied on
      for mounting the root filesystem.
      
      Now, most people never noticed this, because not only is it
      timing-dependent, but modern distributions all use initrd.  So the root
      filesystem isn't actually on a disk at all.  And then before they
      actually mount the final disk filesystem, they will have loaded the
      scsi-wait-scan module, which not only does the expected
      wait_for_device_probe(), but also does scsi_complete_async_scans().
      
      [ Side note: scsi_complete_async_scans() had also been partially broken,
        but that was fixed in commit 43a8d39d ("fix async probe
        regression"), so that same commit a7a20d10 had actually broken
        setups even if you used scsi-wait-scan explicitly ]
      
      Solve this problem by just moving the scsi_complete_async_scans() call
      into wait_for_device_probe().  Everybody who wants to wait for device
      probing to finish really wants the SCSI probing to complete, so there's
      no reason not to do this.
      
      So now "wait_for_device_probe()" really does what the name implies, and
      properly waits for device probing to finish.  This also removes the now
      unnecessary extra calls to scsi_complete_async_scans().
