      HID: hiddev: fix potential Spectre v1 · 4f65245f
      Gustavo A. R. Silva authored
      uref->field_index, uref->usage_index, finfo.field_index and cinfo.index can be
      indirectly controlled by user-space, hence leading to a potential exploitation
      of the Spectre variant 1 vulnerability.
      
      This issue was detected with the help of Smatch:
      
      drivers/hid/usbhid/hiddev.c:473 hiddev_ioctl_usage() warn: potential spectre issue 'report->field' (local cap)
      drivers/hid/usbhid/hiddev.c:477 hiddev_ioctl_usage() warn: potential spectre issue 'field->usage' (local cap)
      drivers/hid/usbhid/hiddev.c:757 hiddev_ioctl() warn: potential spectre issue 'report->field' (local cap)
      drivers/hid/usbhid/hiddev.c:801 hiddev_ioctl() warn: potential spectre issue 'hid->collection' (local cap)
      
      Fix this by sanitizing such structure fields before using them to index
      report->field, field->usage and hid->collection
      
      Notice that given that speculation windows are large, the policy is
      to kill the speculation on the first load and not worry if it can be
      completed with a dependent load/store [1].

      HID: i2c-hid: Fix "incomplete report" noise · ef6eaf27
      Jason Andryuk authored
      
      
      Commit ac75a041 ("HID: i2c-hid: fix size check and type usage") started
      writing messages when the ret_size is <= 2 from i2c_master_recv.  However, my
      device i2c-DLL07D1 returns 2 for a short period of time (~0.5s) after I stop
      moving the pointing stick or touchpad.  It varies, but you get ~50 messages
      each time which spams the log hard.
      
      [  95.925055] i2c_hid i2c-DLL07D1:01: i2c_hid_get_input: incomplete report (83/2)
      
      This has also been observed with a i2c-ALP0017.
      
      [ 1781.266353] i2c_hid i2c-ALP0017:00: i2c_hid_get_input: incomplete report (30/2)
      
      Only print the message when ret_size is totally invalid and less than 2 to cut
      down on the log spam.

      Pull scheduler fixes from Thomas Gleixner:
      
       - The hopefully final fix for the reported race problems in
         kthread_parkme(). The previous attempt still left a hole and was
         partially wrong.
      
       - Plug a race in the remote tick mechanism which triggers a warning
         about updates not being done correctly. That's a false positive if
         the race condition is hit as the remote CPU is idle. Plug it by
         checking the condition again when holding run queue lock.
      
       - Fix a bug in the utilization estimation of a run queue which causes
         the estimation to be 0 when a run queue is throttled.
      
       - Advance the global expiration of the period timer when the timer is
         restarted after a idle period. Otherwise the expiry time is stale and
         the timer fires prematurely.
      
       - Cure the drift between the bandwidth timer and the runqueue
         accounting, which leads to bogus throttling of runqueues
      
       - Place the call to cpufreq_update_util() correctly so the function
         will observe the correct number of running RT tasks and not a stale
         one.
