        ugly unions.
      
        Also included is the try_to_wake_up() race fix that was first

      sched/cfs: change initial value of runnable_avg · e21cf434
      Vincent Guittot authored
      Some performance regression on reaim benchmark have been raised with
        commit 070f5e86 ("sched/fair: Take into account runnable_avg to classify group")
      
      The problem comes from the init value of runnable_avg which is initialized
      with max value. This can be a problem if the newly forked task is finally
      a short task because the group of CPUs is wrongly set to overloaded and
      tasks are pulled less agressively.
      
      Set initial value of runnable_avg equals to util_avg to reflect that there
      is no waiting time so far.

      smp, irq_work: Continue smp_call_function*() and irq_work*() integration · 8c4890d1
      Peter Zijlstra authored
      Instead of relying on BUG_ON() to ensure the various data structures
      line up, use a bunch of horrible unions to make it all automatic.
      
      Much of the union magic is to ensure irq_work and smp_call_function do
      not (yet) see the members of their respective data structures change
      name.

      sched/core: Fix ttwu() race · b6e13e85
      Peter Zijlstra authored
      Paul reported rcutorture occasionally hitting a NULL deref:
      
        sched_ttwu_pending()
          ttwu_do_wakeup()
            check_preempt_curr() := check_preempt_wakeup()
              find_matching_se()
                is_same_group()
                  if (se->cfs_rq == pse->cfs_rq) <-- *BOOM*
      
      Debugging showed that this only appears to happen when we take the new
      code-path from commit:
      
        2ebb1771 ("sched/core: Offload wakee task activation if it the wakee is descheduling")
      
      and only when @cpu == smp_processor_id(). Something which should not
      be possible, because p->on_cpu can only be true for remote tasks.
      Similarly, without the new code-path from commit:
      
        c6e7bd7a ("sched/core: Optimize ttwu() spinning on p->on_cpu")
      
      this would've unconditionally hit:
      
        smp_cond_load_acquire(&p->on_cpu, !VAL);
      
      and if: 'cpu == smp_processor_id() && p->on_cpu' is possible, this
      would result in an instant live-lock (with IRQs disabled), something
      that hasn't been reported.
      
      The NULL deref can be explained however if the task_cpu(p) load at the
      beginning of try_to_wake_up() returns an old value, and this old value
      happens to be smp_processor_id(). Further assume that the p->on_cpu
      load accurately returns 1, it really is still running, just not here.
      
      Then, when we enqueue the task locally, we can crash in exactly the
      observed manner because p->se.cfs_rq != rq->cfs_rq, because p's cfs_rq
      is from the wrong CPU, therefore we'll iterate into the non-existant
      parents and NULL deref.
      
      The closest semi-plausible scenario I've managed to contrive is
      somewhat elaborate (then again, actual reproduction takes many CPU
      hours of rcutorture, so it can't be anything obvious):
      
      					X->cpu = 1
      					rq(1)->curr = X
      
      	CPU0				CPU1				CPU2
      
      					// switch away from X
      					LOCK rq(1)->lock
      					smp_mb__after_spinlock
      					dequeue_task(X)
      					  X->on_rq = 9
      					switch_to(Z)
      					  X->on_cpu = 0
      					UNLOCK rq(1)->lock
      
      									// migrate X to cpu 0
      									LOCK rq(1)->lock
      									dequeue_task(X)
      									set_task_cpu(X, 0)
      									  X->cpu = 0
      									UNLOCK rq(1)->lock
      
      									LOCK rq(0)->lock
      									enqueue_task(X)
      									  X->on_rq = 1
      									UNLOCK rq(0)->lock
      
      	// switch to X
      	LOCK rq(0)->lock
      	smp_mb__after_spinlock
      	switch_to(X)
      	  X->on_cpu = 1
      	UNLOCK rq(0)->lock
      
      	// X goes sleep
      	X->state = TASK_UNINTERRUPTIBLE
      	smp_mb();			// wake X
      					ttwu()
      					  LOCK X->pi_lock
      					  smp_mb__after_spinlock
      
      					  if (p->state)
      
      					  cpu = X->cpu; // =? 1
      
      					  smp_rmb()
      
      	// X calls schedule()
      	LOCK rq(0)->lock
      	smp_mb__after_spinlock
      	dequeue_task(X)
      	  X->on_rq = 0
      
      					  if (p->on_rq)
      
      					  smp_rmb();
      
      					  if (p->on_cpu && ttwu_queue_wakelist(..)) [*]
      
      					  smp_cond_load_acquire(&p->on_cpu, !VAL)
      
      					  cpu = select_task_rq(X, X->wake_cpu, ...)
      					  if (X->cpu != cpu)
      	switch_to(Y)
      	  X->on_cpu = 0
      	UNLOCK rq(0)->lock
      
      However I'm having trouble convincing myself that's actually possible
      on x86_64 -- after all, every LOCK implies an smp_mb() there, so if ttwu
      observes ->state != RUNNING, it must also observe ->cpu != 1.
      
      (Most of the previous ttwu() races were found on very large PowerPC)
      
      Nevertheless, this fully explains the observed failure case.
      
      Fix it by ordering the task_cpu(p) load after the p->on_cpu load,
      which is easy since nothing actually uses @cpu before this.

      sched/core: Fix PI boosting between RT and DEADLINE tasks · 740797ce
      Juri Lelli authored
      syzbot reported the following warning:
      
       WARNING: CPU: 1 PID: 6351 at kernel/sched/deadline.c:628
       enqueue_task_dl+0x22da/0x38a0 kernel/sched/deadline.c:1504
      
      At deadline.c:628 we have:
      
       623 static inline void setup_new_dl_entity(struct sched_dl_entity *dl_se)
       624 {
       625 	struct dl_rq *dl_rq = dl_rq_of_se(dl_se);
       626 	struct rq *rq = rq_of_dl_rq(dl_rq);
       627
       628 	WARN_ON(dl_se->dl_boosted);
       629 	WARN_ON(dl_time_before(rq_clock(rq), dl_se->deadline));
              [...]
           }
      
      Which means that setup_new_dl_entity() has been called on a task
      currently boosted. This shouldn't happen though, as setup_new_dl_entity()
      is only called when the 'dynamic' deadline of the new entity
      is in the past w.r.t. rq_clock and boosted tasks shouldn't verify this
      condition.
      
      Digging through the PI code I noticed that what above might in fact happen
      if an RT tasks blocks on an rt_mutex hold by a DEADLINE task. In the
      first branch of boosting conditions we check only if a pi_task 'dynamic'
      deadline is earlier than mutex holder's and in this case we set mutex
      holder to be dl_boosted. However, since RT 'dynamic' deadlines are only
      initialized if such tasks get boosted at some point (or if they become
      DEADLINE of course), in general RT 'dynamic' deadlines are usually equal
      to 0 and this verifies the aforementioned condition.
      
      Fix it by checking that the potential donor task is actually (even if
      temporary because in turn boosted) running at DEADLINE priority before
      using its 'dynamic' deadline value.

      This function is concerned with the long-term CPU mask, not the
      transitory mask the task might have while migrate disabled.  Before
      this patch, if a task was migrate-disabled at the time
      __set_cpus_allowed_ptr() was called, and the new mask happened to be
      equal to the CPU that the task was running on, then the mask update
      would be lost.

      afs: Fix storage of cell names · 719fdd32
      David Howells authored
      The cell name stored in the afs_cell struct is a 64-char + NUL buffer -
      when it needs to be able to handle up to AFS_MAXCELLNAME (256 chars) + NUL.
      
      Fix this by changing the array to a pointer and allocating the string.
      
      Found using Coverity.

       "The main change here is a fix for a number of unsafe interactions
        between kdb and the console system. The fixes are specific to kdb
        (pure kgdb debugging does not use the console system at all). On
        systems with an NMI then kdb, if it is enabled, must get messages to
        the user despite potentially running from some "difficult" calling
        contexts. These fixes avoid using the console system where we have
        been provided an alternative (safer) way to interact with the user
        and, if using the console system in unavoidable, use oops_in_progress
        for deadlock avoidance. These fixes also ensure kdb honours the
        console enable flag.
      
        Also included is a fix that wraps kgdb trap handling in an RCU read
        lock to avoids triggering diagnostic warnings. This is a wide lock
        scope but this is OK because kgdb is a stop-the-world debugger. When
        we stop the world we put all the CPUs into holding pens and this

       "The big fix here is to our vDSO sigreturn trampoline as, after a
        painfully long stint of debugging, it turned out that fixing some of
        our CFI directives in the merge window lit up a bunch of logic in
        libgcc which has been shown to SEGV in some cases during asynchronous
        pthread cancellation.
      
        It looks like we can fix this by extending the directives to restore
        most of the interrupted register state from the sigcontext, but it's

      FPGA Manager fixes for 5.8-rc1
      
      Here is one (late) fix for 5.8-rc1 merge window.
      
      Arnd's change addresses a missing build dependency.
      
      All patches have been reviewed on the mailing list, and have been in the
