      ALSA: oxfw: add support for Mackie Onyx 1640i · 03abd33a
      Takashi Sakamoto authored
      As of kernel 4.10,  ALSA OXFW driver has no entry for Onyx 1640i produced
      by Mackie (Loud Technologies). This commit supplement it.
      
      I note that there're two models produced by Mackie (Loud Technologies),
      which have the same name 'Onyx 1640i'. The former model based on OXFW970,
      the latter model based on Dice. This is probably due to low quality of
      communication of OXFW series.
      
      Additionally, the tester reports his or her experiences to get unexpected
      result at higher sampling transmission frequency as 88.2/96.0 kHz. We
      didn't have further investigation yet[0].

      net: korina: Fix NAPI versus resources freeing · e6afb1ad
      Florian Fainelli authored
      Commit beb0babf ("korina: disable napi on close and restart")
      introduced calls to napi_disable() that were missing before,
      unfortunately this leaves a small window during which NAPI has a chance
      to run, yet we just freed resources since korina_free_ring() has been
      called:
      
      Fix this by disabling NAPI first then freeing resource, and make sure
      that we also cancel the restart task before doing the resource freeing.

      net, sched: fix soft lockup in tc_classify · 628185cf
      Daniel Borkmann authored
      Shahar reported a soft lockup in tc_classify(), where we run into an
      endless loop when walking the classifier chain due to tp->next == tp
      which is a state we should never run into. The issue only seems to
      trigger under load in the tc control path.
      
      What happens is that in tc_ctl_tfilter(), thread A allocates a new
      tp, initializes it, sets tp_created to 1, and calls into tp->ops->change()
      with it. In that classifier callback we had to unlock/lock the rtnl
      mutex and returned with -EAGAIN. One reason why we need to drop there
      is, for example, that we need to request an action module to be loaded.
      
      This happens via tcf_exts_validate() -> tcf_action_init/_1() meaning
      after we loaded and found the requested action, we need to redo the
      whole request so we don't race against others. While we had to unlock
      rtnl in that time, thread B's request was processed next on that CPU.
      Thread B added a new tp instance successfully to the classifier chain.
      When thread A returned grabbing the rtnl mutex again, propagating -EAGAIN
      and destroying its tp instance which never got linked, we goto replay
      and redo A's request.
      
      This time when walking the classifier chain in tc_ctl_tfilter() for
      checking for existing tp instances we had a priority match and found
      the tp instance that was created and linked by thread B. Now calling
      again into tp->ops->change() with that tp was successful and returned
      without error.
      
      tp_created was never cleared in the second round, thus kernel thinks
      that we need to link it into the classifier chain (once again). tp and
      *back point to the same object due to the match we had earlier on. Thus
      for thread B's already public tp, we reset tp->next to tp itself and
      link it into the chain, which eventually causes the mentioned endless
      loop in tc_classify() once a packet hits the data path.
      
      Fix is to clear tp_created at the beginning of each request, also when
      we replay it. On the paths that can cause -EAGAIN we already destroy
      the original tp instance we had and on replay we really need to start
      from scratch. It seems that this issue was first introduced in commit
      12186be7 ("net_cls: fix unconfigured struct tcf_proto keeps chaining
      and avoid kernel panic when we use cls_cgroup").

      powerpc: Fix build warning on 32-bit PPC · 8ae679c4
      Larry Finger authored
      I am getting the following warning when I build kernel 4.9-git on my
      PowerBook G4 with a 32-bit PPC processor:
      
          AS      arch/powerpc/kernel/misc_32.o
        arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef]
      
      This problem is evident after commit 989cea5c ("kbuild: prevent
      lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an
      error that has been in the code since 2005 when this source file was
      created.  That was with commit 9994a338 ("powerpc: Introduce
      entry_{32,64}.S, misc_{32,64}.S, systbl.S").
      
      The offending line does not make a lot of sense.  This error does not
      seem to cause any errors in the executable, thus I am not recommending
      that it be applied to any stable versions.
      
      Thanks to Nicholas Piggin for suggesting this solution.
