      dt-bindings: net: ave: Use unevaluatedProperties · 5a80059d
      Kunihiko Hayashi authored
      
      This refers common bindings, so this is preferred for
      unevaluatedProperties instead of additionalProperties.

      dt-bindings: net: ave: Clean up clocks, resets, and their names using compatible string · 2610bd72
      Kunihiko Hayashi authored
      
      Instead of "oneOf:" choices, use "allOf:" and "if:" to define clocks,
      resets, and their names that can be taken by the compatible string.
      
      The order of clock-names and reset-names doesn't change here.

      Pull random number generator fixes from Jason Donenfeld:
      
       - Another fixup to the fast_init/crng_init split, this time in how much
         entropy is being credited, from Jan Varho.
      
       - As discussed, we now opportunistically call try_to_generate_entropy()
         in /dev/urandom reads, as a replacement for the reverted commit. I
         opted to not do the more invasive wait_for_random_bytes() change at
         least for now, preferring to do something smaller and more obvious
         for the time being, but maybe that can be revisited as things evolve
         later.
      
       - Userspace can use FUSE or userfaultfd or simply move a process to
         idle priority in order to make a read from the random device never
         complete, which breaks forward secrecy, fixed by overwriting
         sensitive bytes early on in the function.
      
       - Jann Horn noticed that /dev/urandom reads were only checking for
         pending signals if need_resched() was true, a bug going back to the
         genesis commit, now fixed by always checking for signal_pending() and
         calling cond_resched(). This explains various noticeable signal
         delivery delays I've seen in programs over the years that do long
         reads from /dev/urandom.
      
       - In order to be more like other devices (e.g. /dev/zero) and to
         mitigate the impact of fixing the above bug, which has been around
         forever (users have never really needed to check the return value of
         read() for medium-sized reads and so perhaps many didn't), we now
         move signal checking to the bottom part of the loop, and do so every
         PAGE_SIZE-bytes.

        random: opportunistically initialize on /dev/urandom reads

      drivers: net: slip: fix NPD bug in sl_tx_timeout() · ec4eb8a8
      Duoming Zhou authored
      
      When a slip driver is detaching, the slip_close() will act to
      cleanup necessary resources and sl->tty is set to NULL in
      slip_close(). Meanwhile, the packet we transmit is blocked,
      sl_tx_timeout() will be called. Although slip_close() and
      sl_tx_timeout() use sl->lock to synchronize, we don`t judge
      whether sl->tty equals to NULL in sl_tx_timeout() and the
      null pointer dereference bug will happen.
      
         (Thread 1)                 |      (Thread 2)
                                    | slip_close()
                                    |   spin_lock_bh(&sl->lock)
                                    |   ...
      ...                           |   sl->tty = NULL //(1)
      sl_tx_timeout()               |   spin_unlock_bh(&sl->lock)
        spin_lock(&sl->lock);       |
        ...                         |   ...
        tty_chars_in_buffer(sl->tty)|
          if (tty->ops->..) //(2)   |
          ...                       |   synchronize_rcu()
      
      We set NULL to sl->tty in position (1) and dereference sl->tty
      in position (2).
      
      This patch adds check in sl_tx_timeout(). If sl->tty equals to
      NULL, sl_tx_timeout() will goto out.
