      Update TDA998x maintainer entry · bdf33113
      Russell King - ARM Linux authored
      Update my TDA998x HDMI encoder MAINTAINERS entry to include the
      dt-bindings header, and a keyword pattern to catch patches containing
      the DT compatible.  Also change the status to "maintained" rather than
      "supported".

      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.

      Fix up non-directory creation in SGID directories · 0fa3ecd8
      Linus Torvalds authored
      sgid directories have special semantics, making newly created files in
      the directory belong to the group of the directory, and newly created
      subdirectories will also become sgid.  This is historically used for
      group-shared directories.
      
      But group directories writable by non-group members should not imply
      that such non-group members can magically join the group, so make sure
      to clear the sgid bit on non-directories for non-members (but remember
      that sgid without group execute means "mandatory locking", just to
      confuse things even more).
