PATCH 1/6 Cleanups and fixes for RCU in face of heavy CPU-hotplug stress

This patch set provides the following cleanups and fixes for RCU in workloads that involve lots of CPU hotplugging. Ingo, please reset core/rcu to 240ebbf before applying these patches.

o Split Hierarchical RCU initialization into boot-time and
CPU-hotplug pieces, so that other CPUs never see the data structures in the act of being stitched together.

o Introduce a cpu_notifier() that works as does the current
hotcpu_notifier(), but also notifies during boot time even if !HOTPLUG_CPU.

o Make RCU use the new cpu_notifier() to simplify hotplug code
and reduce the number of notifiers in use. (This also fixes the problem Ingo and Hugh found.)

o Preemptable RCU had a bug due to its overly clever attempt
to move counts from CPUs going offline. This is "unsafe at any speed", so remove the cleverness.

o Since offline CPUs now can have non-zero counts, they must
now be included in the tracing.

o Fix typo in preemptable RCU's rcu_irq_enter() comment
submitted by Josh Triplett.

These pass tests combining rcutorture and continuous CPU-hotplug operations, in other words, no sleeping between successive CPU-hotplug operations. This set does not fix the bug involving deadlocks through rcutorture, kthread_stop(), and migration threads. However, this bug does not affect production systems, so should not stand in the way of applying these patches.

Thanx, Paul

PATCH 1/6 Split hierarchical RCU initialization into boot-time and CPU-online pieces

This patch divides the rcutree initialization into boot-time and hotplug-time components, so that the tree data structures are guaranteed to be fully linked at boot time regardless of what might happen in CPU hotplug operations. This makes RCU more resilient against CPU hotplug misbehavior (and vice versa), but more importantly, does a better job of compartmentalizing the code.

These two definitions seem inconsistent. I think the first one needs to change to use do { ... } while(0) as well, so it eats the subsequent semicolon.

Does this really want to live under defined(CONFIG_HOTPLUG_CPU)? What happens when onlining CPUs during the !define(CONFIG_HOTPLUG_CPU) case? This seems somewhat inconsistent with the explanation in your commit message; can you clarify?

Also, why !defined(MODULE)?

Ha! I just copied the old hotcpu_notifier style. Will send a patch fixing both. Or feel free to send one, if you wish.

The !MODULE covers the !define(CONFIG_HOTPLUG_CPU) case, please see below.

Quoted 1 line

Also, why !defined(MODULE)?

Here is how the cases lay out:

o !CONFIG_SMP: there is only one CPU, and so there can be no
CPU-hotplug operations, even at boot. Therefore, the cpu_notifier() need do nothing.

o CONFIG_SMP && CPU_HOTPLUG_CPU: CPUs can come and go at any
time, so we need cpu_notifier() to actually register a notifier.

o CONFIG_SMP && !CPU_HOTPLUG_CPU && MODULE: CPUs cannot go
offline, but they do come online at boot time. But MODULE means
that this code is in a module, and modules cannot be loaded until later, after all CPUs have come online. So cpu_notifier() need do nothing in this case.

o CONFIG_SMP && !CPU_HOTPLUG_CPU && !MODULE: CPUs cannot go
offline, but they do come online at boot time. This code is not in a module, so might be running at boot time, and thus might need to deal with CPUs coming online. Therefore, cpu_notifier() must actually register a notifier.

The difference between hotcpu_notifier() and cpu_notifier() is in this last case. You would use hotcpu_notifier() for non-module code that did not run until all CPUs had come online, and thus would not need to deal with CPU hotplug unless HOTPLUG_CPU was actually defined.

Thanx, Paul

PATCH 3/6 Simplify RCU CPU-hotplug notification

In reply to Paul E. McKenney

From: Paul E. McKenney <[email protected]>

Use the new cpu_notifier() API to simplify RCU's CPU-hotplug notifiers, collapsing down to a single such notifier. This makes it trivial to provide the notifier-ordering guarantee that rcu_barrier() depends on. Also remove redundant open_softirq() calls from Hierarchical RCU notifier.

rcu: Simplify RCU CPU-hotplug notification

Use the new cpu_notifier() API to simplify RCU's CPU-hotplug notifiers, collapsing down to a single such notifier.

This makes it trivial to provide the notifier-ordering guarantee that rcu_barrier() depends on.

Also remove redundant open_softirq() calls from Hierarchical RCU notifier.

Indeed there is. But I wouldn't put it past the fast-boot guys to parallelize early boot. ;-)

PATCH 4/6 Make preemptable RCU scan all CPUs when summing RCU counters.

In reply to Paul E. McKenney

From: Paul E. McKenney <[email protected]>

This patch eliminates the counter-moving during CPU-offline notifiers, eliminating potential confusion if counters are scanned during counter-movement process. This confusion could result in premature ending of an RCU grace period. For example, if there are two tasks in RCU read-side critical sections (so that the sum of the counters is two), and the counter for the CPU going offline is -2, then moving the count to another CPU can result in the sum momentarily appearing to be zero. Since there are no memory barriers in either case, many more such scenarios are possible.

So just don't move the counts!!!

Indeed it is!!!

Well, now I know why one uses "git am" even when just making the change would be less typing. Sorry for my confusion!!!

Thanx, Paul

These pass tests combining rcutorture and continuous CPU-hotplug operations, in other words, no sleeping between successive CPU-hotplug operations. This set does not fix the bug involving deadlocks through rcutorture, kthread_stop(), and migration threads. However, this bug does not affect production systems, so should not stand in the way of applying these patches.

Commit 63706172f332fd3f6e7458ebfb35fa6de9c21dc5, "kthreads: rework kthread_stop()", looks like it fixes kthread_stop to work concurrently. That may fix the issue you observed.

Very cool!!! Given that Oleg is the author, it probably also works. :-)

FYI, i've started triggering hangs in -tip testing recently, during CPU hotplug tests:

config and bootlog attached. I'd suspect one of these patches:

684ca5c: rcu: Fix typo in rcu_irq_exit() comment header
b612ba8: rcu: Make rcupreempt_trace.c look at offline CPUs
8064d54: rcu: Make preemptable RCU scan all CPUs when summing RCU counters 2e59755: rcu: Simplify RCU CPU-hotplug notification
799e64f: cpu hotplug: Introduce cpu_notifier() to handle !HOTPLUG_CPU case 2756962: rcu: Split hierarchical RCU initialization into boot-time and CPU-online piece

Any ideas?

Gah... I thought I had fixed that one!!! I was seeing a deadlock where rcu_barrier_cpu_hotplug() would register the three RCU callbacks, then wait for them. But in some situations, it would wait for them in a state such that grace period could not complete. I convinced myself that moving the wait back from CPU_DEAD to CPU_POST_DEAD solved the problem.

I am going to take a more bullet-proof approach, switching from the wait_completion() form to wait_event(), which will allow me to wait for the previous hotplug operation's callbacks at the beginning of the subsequent hotplug operation.

I reserve the right to insert a short delay in the CPU-hotplug path outside of any locks, but would imagine that people would prefer that I avoid that sort of thing, at least until we have bulk CPU-hotplug operations.

Thanx, Paul

I reserve the right to insert a short delay in the CPU-hotplug path outside of any locks, but would imagine that people would prefer that I avoid that sort of thing, at least until we have bulk CPU-hotplug operations.

And here is a patch that is doing well in testing thus far. (On the other hand tip/core/rcu did fine in my testing.) I am not 100% confident that this new patch hitting the core RCU/CPU-hotplug issue, but this is in any case helpful in getting an RCU grace period off of the CPU hotunplug critical path.

Feel free to test if convenient. The other thing I am considering is moving the registering of the three rcu_migrate_head callbacks from the CPU_DYING notifier to the CPU_POST_DEAD notifier.

Thanx, Paul

------------------------------------------------------------------------

Delay rcu_barrier() wait until beginning of next CPU-hotunplug operation.

This change moves an RCU grace period delay off of the critical path for CPU-hotunplug operations. Since RCU callback migration is only performed on CPU-hotunplug operations, and since the rcu_barrier() race is provoked only by consecutive CPU-hotunplug operations, it is not necessary to delay the end of a given CPU-hotunplug operation. We can instead choose to delay the beginning of the next CPU-hotunplug operation, as shown by the following patch.

Thanks Paul, i've queued it up and started testing it. It took quite some time to trigger it so the test period needed will be measured in days (perhaps up to a week), not minutes or hours.

Gah... I thought I had fixed that one!!! I was seeing a deadlock where rcu_barrier_cpu_hotplug() would register the three RCU callbacks, then wait for them. But in some situations, it would wait for them in a state such that grace period could not complete. I convinced myself that moving the wait back from CPU_DEAD to CPU_POST_DEAD solved the problem.
I am going to take a more bullet-proof approach, switching from the wait_completion() form to wait_event(), which will allow me to wait for the previous hotplug operation's callbacks at the beginning of the subsequent hotplug operation.

I reserve the right to insert a short delay in the CPU-hotplug path outside of any locks, but would imagine that people would prefer that I avoid that sort of thing, at least until we have bulk CPU-hotplug operations.
And here is a patch that is doing well in testing thus far. (On the other hand tip/core/rcu did fine in my testing.) I am not 100% confident that this new patch hitting the core RCU/CPU-hotplug issue, but this is in any case helpful in getting an RCU grace period off of the CPU hotunplug critical path.
Feel free to test if convenient. The other thing I am considering is moving the registering of the three rcu_migrate_head callbacks from the CPU_DYING notifier to the CPU_POST_DEAD notifier.

Delay rcu_barrier() wait until beginning of next CPU-hotunplug operation.
This change moves an RCU grace period delay off of the critical path for CPU-hotunplug operations. Since RCU callback migration is only performed on CPU-hotunplug operations, and since the rcu_barrier() race is provoked only by consecutive CPU-hotunplug operations, it is not necessary to delay the end of a given CPU-hotunplug operation. We can instead choose to delay the beginning of the next CPU-hotunplug operation, as shown by the following patch.

Why is wait_migrated_callbacks() called by

static void _rcu_barrier(enum rcu_barrier type) ?

I would have expected it to be only called by rcu_barrier_cpu_hotplug(), so that wait_event() would match the number of wakeup().

I think if we have a race between

- rcu_barrier_cpu_hotplug(..., CPU_DYING) (on the dying cpu, with stop_machine())
- _rcu_barrier (on another CPU) -> wait_event() on false cond., calls schedule()

then execution of

- rcu_barrier_cpu_hotplug(..., CPU_POST_DEAD) (on the CPU handling the hotunplug request) -> wait_event() on false cond., calls schedule()
...
- eventually, all the RCU callbacks have been executed, including the 3 migration callbacks -> wakeup()
-> would only wake up _rcu_barrier.

Therefore, rcu_barrier_cpu_hotplug() would be sitting there waiting forever.

Maybe wake_up_all() would be more appropriate ?

Then I don't see how you deal with concurrency between multiple _rcu_barrier(). wait_event() is done outside of the mutex.

Any ideas?
Gah... I thought I had fixed that one!!! I was seeing a deadlock where rcu_barrier_cpu_hotplug() would register the three RCU callbacks, then wait for them. But in some situations, it would wait for them in a state such that grace period could not complete. I convinced myself that moving the wait back from CPU_DEAD to CPU_POST_DEAD solved the problem.
I am going to take a more bullet-proof approach, switching from the wait_completion() form to wait_event(), which will allow me to wait for the previous hotplug operation's callbacks at the beginning of the subsequent hotplug operation.
Quoted 4 lines
I reserve the right to insert a short delay in the CPU-hotplug path outside of any locks, but would imagine that people would prefer that I avoid that sort of thing, at least until we have bulk CPU-hotplug operations.
And here is a patch that is doing well in testing thus far. (On the other hand tip/core/rcu did fine in my testing.) I am not 100% confident that this new patch hitting the core RCU/CPU-hotplug issue, but this is in any case helpful in getting an RCU grace period off of the CPU hotunplug critical path.
Feel free to test if convenient. The other thing I am considering is moving the registering of the three rcu_migrate_head callbacks from the CPU_DYING notifier to the CPU_POST_DEAD notifier.
Thanx, Paul
------------------------------------------------------------------------
Delay rcu_barrier() wait until beginning of next CPU-hotunplug operation.
This change moves an RCU grace period delay off of the critical path for CPU-hotunplug operations. Since RCU callback migration is only performed on CPU-hotunplug operations, and since the rcu_barrier() race is provoked only by consecutive CPU-hotunplug operations, it is not necessary to delay the end of a given CPU-hotunplug operation. We can instead choose to delay the beginning of the next CPU-hotunplug operation, as shown by the following patch.

Why is wait_migrated_callbacks() called by
static void _rcu_barrier(enum rcu_barrier type) ?
I would have expected it to be only called by rcu_barrier_cpu_hotplug(), so that wait_event() would match the number of wakeup().
I think if we have a race between
- rcu_barrier_cpu_hotplug(..., CPU_DYING) (on the dying cpu, with stop_machine())
- _rcu_barrier (on another CPU) -> wait_event() on false cond., calls schedule()
then execution of
- rcu_barrier_cpu_hotplug(..., CPU_POST_DEAD) (on the CPU handling the hotunplug request) -> wait_event() on false cond., calls schedule()
...
- eventually, all the RCU callbacks have been executed, including the 3 migration callbacks -> wakeup()
-> would only wake up _rcu_barrier.

Therefore, rcu_barrier_cpu_hotplug() would be sitting there waiting forever.
Thank you for taking a careful look at this! Color me blind!!!

Maybe wake_up_all() would be more appropriate ?
Or using two different wait queues.
Then I don't see how you deal with concurrency between multiple _rcu_barrier(). wait_event() is done outside of the mutex.

You are right -- I cannot see an alternative to wake_up_all(). There could be one hotplug notifier and an arbitrary number of rcu_barrier() invocations sleeping on the wait queue. Testing is in progress.

I would not trust this architecture for synchronization tests. There has been reports of a hardware bug affecting the cmpxchg instruction in the field. The load fence normally implied by the semantic seems to be missing. AFAIK, AMD never acknowledged the problem.

So far I have proposed a best effort fix for this (patching in an lfence after cmpxchg), but userspace would still be buggy.

http://lkml.indiana.edu/hypermail/linux/kernel/0904.2/03024.html

However, in this particular RCU case, __wait_event() calls prepare_to_wait() which uses set_current_state(). This in turn uses xchg(), which has an implied memory barrier. This barrier is required for proper ordering of the condition test wrt preparing the wait queue. Maybe it would be worth checking if amd did not screw up the xchg instruction too on this architecture.

So I am not saying that there is not another bug hidden somewhere, but until this can be reproduced on a different architecture, I think we should consider that the problem might be caused by missing hardware synchronization.

If cmpxchg was broken i'd be having far worse problems and very widely so.

FYI, this was the same box i prototyped/developed -rt on, which uses cmpxchg for _everything_.

That's not a proof of course (it's near impossible to prove the lack of a bug), but it's sure a strong indicator and you'll need to provide far more proof of misbehavior before i discount a bona fide regression on this box.

I believe Mathieu is suggesting that the hardware bug is not that the compare and exchange does not work in cmpxchg, but that it does not provide an explicit memory barrier. Such a bug is very hard to trigger, since it requires a race that allows a memory write/read to cross the cmpxchg, and then have this be in such a place that it will cause harm.

Yep, I think we should continue looking for the problem cause, but stress-testing the hardware with the program I just sent cannot hurt. :)

You are right, the race condition is unlikely. Finally AMD issued an
errata: #147

Potential Violation of Read Ordering Rules Between Semaphore Operations and Unlocked Read-Modify-Write Instructions

http://support.amd.com/us/Processor_TechDocs/25759.pdf

One needs to have this kind of instruction sequence:

lock; cmpxchg
cmpxchg

to hit the problem, which seems to be a pattern unlikely to happen in the kernel. Maybe except in ftrace, with a combination of spinlock and cmpxchg_local().

FWIW, I created a small test program which aims at triggering the problem. So far my AMD box did not show any symptom (although the CPU family, model and MSR values indicate that it should be affected).

The following program is actually pretty useful to stress-test memory barriers.
