[PATCH 0/2] nohz: Deal with clock reprogram skipping issues v2

[Frederic Weisbecker]

As suggested by Thomas Gleixner, the second patch now integrates
a fix in case the sanity check fails and the clockevent isn't programmed
as expected.

Frederic Weisbecker (2):
  nohz: Fix again collision between tick and other hrtimers
  tick: Make sure tick timer is active when bypassing reprogramming

[PATCH 1/2] nohz: Fix again collision between tick and other hrtimers

[Frederic Weisbecker]

(This restores commit 24b91e360ef521a2808771633d76ebc68bd5604b that got
reverted by commit 558e8e27e73f53f8a512485be538b07115fe5f3c due to a
regression where CPUs spuriously stopped ticking. The issue happened
when a tick fired too early past its expected expiration: on IRQ exit
the tick was scheduled again to the same deadline but skipped
reprogramming because ts->next_tick still kept in cache the deadline.
This has been fixed now with resetting ts->next_tick from the tick
itself. Extra care has also been taken to prevent from obsolete values
throughout CPU hotplug operations.)

When the tick is stopped and an interrupt occurs afterward, we check on
that interrupt exit if the next tick needs to be rescheduled. If it
doesn't need any update, we don't want to do anything.

In order to check if the tick needs an update, we compare it against the
clockevent device deadline. Now that's a problem because the clockevent
device is at a lower level than the tick itself if it is implemented
on top of hrtimer.

Every hrtimer share this clockevent device. So comparing the next tick
deadline against the clockevent device deadline is wrong because the
device may be programmed for another hrtimer whose deadline collides
with the tick. As a result we may end up not reprogramming the tick
accidentally.

In a worst case scenario under full dynticks mode, the tick stops firing
as it is supposed to every 1hz, leaving /proc/stat stalled:

      Task in a full dynticks CPU
      ----------------------------

      * hrtimer A is queued 2 seconds ahead
      * the tick is stopped, scheduled 1 second ahead
      * tick fires 1 second later
      * on tick exit, nohz schedules the tick 1 second ahead but sees
        the clockevent device is already programmed to that deadline,
        fooled by hrtimer A, the tick isn't rescheduled.
      * hrtimer A is cancelled before its deadline
      * tick never fires again until an interrupt happens...

In order to fix this, store the next tick deadline to the tick_sched
local structure and reuse that value later to check whether we need to
reprogram the clock after an interrupt.

On the other hand, ts->sleep_length still wants to know about the next
clock event and not just the tick, so we want to improve the related
comment to avoid confusion.

nohz: Fix collision between tick and other hrtimers, again

This restores commit:

  24b91e360ef5: ("nohz: Fix collision between tick and other hrtimers")

... which got reverted by commit:

  558e8e27e73f: ('Revert "nohz: Fix collision between tick and other hrtimers"')

... due to a regression where CPUs spuriously stopped ticking.

The bug happened when a tick fired too early past its expected expiration:
on IRQ exit the tick was scheduled again to the same deadline but skipped
reprogramming because ts->next_tick still kept in cache the deadline.
This has been fixed now with resetting ts->next_tick from the tick
itself. Extra care has also been taken to prevent from obsolete values
throughout CPU hotplug operations.

When the tick is stopped and an interrupt occurs afterward, we check on
that interrupt exit if the next tick needs to be rescheduled. If it
doesn't need any update, we don't want to do anything.

In order to check if the tick needs an update, we compare it against the
clockevent device deadline. Now that's a problem because the clockevent
device is at a lower level than the tick itself if it is implemented
on top of hrtimer.

Every hrtimer share this clockevent device. So comparing the next tick
deadline against the clockevent device deadline is wrong because the
device may be programmed for another hrtimer whose deadline collides
with the tick. As a result we may end up not reprogramming the tick
accidentally.

In a worst case scenario under full dynticks mode, the tick stops firing
as it is supposed to every 1hz, leaving /proc/stat stalled:

[PATCH 2/2] tick: Make sure tick timer is active when bypassing reprogramming

[Frederic Weisbecker]

So far we have run into too much troubles with the optimization path
that skips reprogramming the clock on IRQ exit when the expiration
deadline hasn't changed. If by accident the cached deadline happens to
be out of sync with the hardware deadline, the buggy result and its
cause are hard to investigate. So lets detect and warn about the issue
early.

tick: Make sure tick timer is active when bypassing reprogramming

So far we have run into too much troubles with the optimization path
that skips reprogramming the clock on IRQ exit when the expiration
deadline hasn't changed. If by accident the cached deadline happens to
be out of sync with the hardware deadline, the buggy result and its
cause are hard to investigate. So lets detect and warn about the issue
early.

I seem to be hitting that in a KVM vm, even without load (sometimes
right after boot):

Ah, can you tell me which tree you were using? Is it tip/master?
Can you give me its HEAD and your config file?

Thanks

Thanks Sasha!

I couldn't reproduce it, that config boots fine on my kvm.
Would you have the time to dump some traces for me?

I'd need you to add this boot option: trace_event=hrtimer_cancel,hrtimer_start,hrtimer_expire_entry
And boot your kernel with the below patch. This will dump the timer traces to your console.
I would be very interested in the resulting console dump file.

Thanks!

Great! So now I can deduce that the problem doesn't come from the nohz code as
ts->next_tick matches the hrtimer deadline. But the dev->next_event from the
clockevent seems to be out of line.

Sorry to bother you again, but I'm chasing this bug for several weeks now and
you're one of the rare person who can reproduce it. So I may need some more
tracing details.

Here is another version of the debugging patch (not a delta), I added more trace_printk,
namely the places where we set this dev->next_event. Can you please apply the below and do
the dump again?

I'm adding a boot option as well for the stacktrace:

trace_event=hrtimer_cancel,hrtimer_start,hrtimer_expire_entry trace_options=stacktrace

Thanks a lot!

Awesome, these traces have been very helpful! So now I think I get what's going on.
Can you please test the following fix?

Thanks a lot!

Subject: [PATCH] nohz: Fix spurious warning when hrtimer and clockevent get
 out of sync

The sanity check ensuring that the tick expiry cache (ts->next_tick)
is actually in sync with the hardware clock (dev->next_event) makes the
wrong assumption that the clock can't be programmed later than the
hrtimer deadline.

In fact the clock hardware can be programmed later on some conditions
such as:

    * The hrtimer deadline is already in the past.
    * The hrtimer deadline is earlier than the minimum delay supported
      by the hardware.

Such conditions can be met when we program the tick, for example if the
last jiffies update hasn't been seen by the current CPU yet, we may
program the hrtimer to a deadline that is earlier than ktime_get()
because last_jiffies_update is our timestamp base to compute the next
tick.

As a result, we can randomly observe such warning:

	WARNING: CPU: 5 PID: 0 at kernel/time/tick-sched.c:794 tick_nohz_stop_sched_tick kernel/time/tick-sched.c:791 [inline]
	Call Trace:
	 tick_nohz_irq_exit
	 tick_irq_exit
	 irq_exit
	 exiting_irq
	 smp_call_function_interrupt
	 smp_call_function_single_interrupt
	 call_function_single_interrupt

Therefore, let's rather make sure that the tick expiry cache is sync'ed
with the tick hrtimer deadline, against which it is not supposed to
drift away. The clock hardware instead has its own will and can't be
used as a reliable comparison point.

Oh sorry, I inverted some conditional. It warns as soon as the tick is completely stopped
and not just deferred, which seldom happen on my testbox.

I need to learn programming again.

Here is the fixed version:

Subject: [PATCH] nohz: Fix spurious warning when hrtimer and clocksource get
 out of sync

The sanity check ensuring that the tick expiry cache (ts->next_tick)
is actually in sync with the hardware clock (dev->next_event) makes the
wrong assumption that the clock can't be programmed later than the
hrtimer deadline.

In fact the clock hardware can be programmed later on some conditions
such as:

    * The hrtimer deadline is already in the past.
    * The hrtimer deadline is earlier than the minimum delay supported
      by the hardware.

Such conditions can be met when we program the tick, for example if the
last jiffies update hasn't been seen by the current CPU yet, we may
program the hrtimer to a deadline that is earlier than ktime_get()
because last_jiffies_update is our timestamp base to compute the next
tick.

As a result, we can randomly observe such warning:

	WARNING: CPU: 5 PID: 0 at kernel/time/tick-sched.c:794 tick_nohz_stop_sched_tick kernel/time/tick-sched.c:791 [inline]
	Call Trace:
	 tick_nohz_irq_exit
	 tick_irq_exit
	 irq_exit
	 exiting_irq
	 smp_call_function_interrupt
	 smp_call_function_single_interrupt
	 call_function_single_interrupt

Therefore, let's rather make sure that the tick expiry cache is sync'ed
with the tick hrtimer deadline, against which it is not supposed to
drift away. The clock hardware instead has its own will and can't be
used as a reliable comparison point.

Oh I'll never be done with that bug :)

Ok I just booted your config with tip/master and didn't see the warning.
But the boot seem to be stalled some time after mounting the root fs.

Can you please try the following patch and tell me what it returns to you?

diff --git a/kernel/time/tick-sched.c b/kernel/time/tick-sched.c

Here's what it prints:

[  707.251791] basemono: 706016000000 ts->next_tick: 693216000000 dev->next_event: 706016406127

Full bootlog attached.

So weird...

Ok I'm going to need serious traces. Can you please add this boot option?

    trace_event=hrtimer_cancel,hrtimer_start,hrtimer_expire_entry

And please also apply the following (on top of tip/tmp.tmp), it would be interesting to see
the resulting trace file from the CPU where the warning triggers.

Thanks Ingo!

Sorry, don't have the time for extensive traces this close to the merge window - 
but are you sure you cannot reproduce it?

The warning popped up on all 3 test systems I tried (two Intel servers, one AMD 
server), and it also hit Mike's server - with a fairly regular distro-ish config.

Thanks,

Fair point, I'll try on other machines than my main one.

Thanks.
