I think I found the root cause of the problem after several kvm runs. The problem is that earlier we were waiting on nocb_head and now we are waiting on nocb_leader_wake. So there are a lot of nocb callbacks which are enqueued before the nocb thread is spawned. This sets up nocb_head to be non-null, because of which the nocb kthread used to wake up immediately after sleeping. Now that we have switched to nocb_leader_wake, this is not being set when there are pending callbacks, unless the callbacks overflow the qhimark. The pending callbacks were around 7000 when the boot hangs. So setting the qhimark using the boot parameter rcutree.qhimark=5000 is one way to allow us to boot past the point by forcefully waking up the nocb kthread. I am not sure this is fool-proof. Another option to start the nocb kthreads with nocb_leader_wake set, so that it can handle any pending callbacks. The following patch also allows us to boot properly. Phew!

I am not sure this is fool-proof. Unfortunately, not in all cases. A small kernel for embedded use might register only a few callbacks during boot, which could still result in a hang. > Another option to start the nocb kthreads with nocb_leader_wake set, > so that it can handle any pending callbacks.

Another possibility is that the early_initcall function doing the synchronize_rcu() is happening before the early_initcall creating the RCU grace-period kthreads. Seems like we need to close both holes. Let's see how your patch works for Amit, and I am testing a patch for the possible early_initcall ordering issue. > diff --git a/kernel/rcu/tree_plugin.h b/kernel/rcu/tree_plugin.h > index 00dc411..4c397aa 100644 > --- a/kernel/rcu/tree_plugin.h > +++ b/kernel/rcu/tree_plugin.h > @@ -2386,6 +2386,9 @@ static int rcu_nocb_kthread(void *arg) > struct rcu_head **tail; > struct rcu_data *rdp = arg; > > + if (rdp->nocb_leader == rdp) > + rdp->nocb_leader_wake = true; > + Not that it matters all that much, but given that the followers don't ever reference ->nocb_leader_wake, we should be able to set this flag unconditionally.

I checked the init call which is calling synchronize_rcu(): subsys_initcall(pm_sysrq_init); this is being called after early_initcall. The order of initcalls is early, core, postcore, arch, subsys, fs, device, late. So I guess that is ok. I wonder why it was not showing up in 12.04. I have a dual boot.

Very good!!! Pranith, I can take this patch, but would you be willing to invert the sense of ->nocb_leader_wake (e.g., call it ->nocb_leader_sleep or some such)? This field is only used in eight places in the source code. The idea is that inverting the sense of the field allows the normal C initialization of zero to properly initialize this field, plus it gets rid of a few lines of code.

This series provides a couple of callback-offloading changes: 1. Parallelize and economize NOCB kthread wakeups to better handle cases where callback offloading is used on workloads that have many context switches and thus many grace periods. 2. Don't offload callbacks for a given CPU unless it has been explicitly requested for that CPU, either directly at build time or boot time, or indirectly at boot time due to that CPU being a nohz_full CPU.

McKenney From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com> An 80-CPU system with a context-switch-heavy workload can require so many NOCB kthread wakeups that the RCU grace-period kthreads spend several tens of percent of a CPU just awakening things. This clearly will not scale well: If you add enough CPUs, the RCU grace-period kthreads would get behind, increasing grace-period latency. To avoid this problem, this commit divides the NOCB kthreads into leaders and followers, where the grace-period kthreads awaken the leaders each of whom in turn awakens its followers. By default, the number of groups of kthreads is the square root of the number of CPUs, but this default may be overridden using the rcutree.rcu_nocb_leader_stride boot parameter. This reduces the number of wakeups done per grace period by the RCU grace-period kthread by the square root of the number of CPUs, but of course by shifting those wakeups to the leaders. In addition, because the leaders do grace periods on behalf of their respective followers, the number of wakeups of the followers decreases by up to a factor of two. Instead of being awakened once when new callbacks arrive and again at the end of the grace period, the followers are awakened only at the end of the grace period. For a numerical example, in a 4096-CPU system, the grace-period kthread would awaken 64 leaders, each of which would awaken its 63 followers at the end of the grace period. This compares favorably with the 79 wakeups for the grace-period kthread on an 80-CPU system. Reported-by: Rik van Riel <riel@redhat.com> Signed-off-by: Paul E.

I am at commit a7d7a143d0b4c, in case that makes a difference. There are some things in your dmesg that look quite strange to me, though. You have "--smp 2" above, but in your dmesg I see the following: [ 0.000000] setup_percpu: NR_CPUS:4 nr_cpumask_bits:4 nr_cpu_ids:1 nr_node_ids:1 So your run somehow only has one CPU. RCU agrees that there is only one CPU: [ 0.000000] Preemptible hierarchical RCU implementation. [ 0.000000] RCU debugfs-based tracing is enabled. [ 0.000000] RCU lockdep checking is enabled. [ 0.000000] Additional per-CPU info printed with stalls. [ 0.000000] RCU restricting CPUs from NR_CPUS=4 to nr_cpu_ids=1. [ 0.000000] Offload RCU callbacks from all CPUs [ 0.000000] Offload RCU callbacks from CPUs: 0. [ 0.000000] RCU: Adjusting geometry for rcu_fanout_leaf=16, nr_cpu_ids=1 [ 0.000000] NO_HZ: Full dynticks CPUs: 1-3. But NO_HZ thinks that there are four. This appears to be due to NO_HZ looking at the compile-time constants, and I doubt that this would cause a problem. But if there really is a CPU 1 that RCU doesn't know about, and it queues a callback, that callback will never be invoked, and you could easily see hangs. Give that your .config says CONFIG_NR_CPUS=4 and your qemu says "--smp 2", why does nr_cpu_ids think that there is only one CPU? Are you running this on a non-x86_64 CPU so that qemu only does UP or some such? The following is what I get (and what I would expect) with that setup: [ 0.000000] Hierarchical RCU implementation. [ 0.000000] RCU debugfs-based tracing is enabled. [ 0.000000] RCU lockdep checking is enabled. [ 0.000000] Additional per-CPU info printed with stalls.

[ 0.000000] RCU: Adjusting geometry for rcu_fanout_leaf=16, nr_cpu_ids=2 [ 0.000000] NO_HZ: Full dynticks CPUs: 1-3. So whatever did you do with CPU 1? ;-) Of course, if I tell qemu "--smp 1" instead of "--smp 2", then RCU thinks that there is only one CPU: [ 0.000000] Hierarchical RCU implementation. [ 0.000000] RCU debugfs-based tracing is enabled. [ 0.000000] RCU lockdep checking is enabled. [ 0.000000] Additional per-CPU info printed with stalls.

And the version of qemu doesn't matter; happens on F20's qemu-kvm-1.6.2-7.fc20.x86_64 as well as qemu.git compiled locally. > There are some things in your dmesg that look quite strange to me, though. > > You have "--smp 2" above, but in your dmesg I see the following: > > [ 0.000000] setup_percpu: NR_CPUS:4 nr_cpumask_bits:4 > nr_cpu_ids:1 nr_node_ids:1 > > So your run somehow only has one CPU. RCU agrees that there is only > one CPU: Yea; indeed. There are MTRR warnings too; attaching the boot log of failed run and diff to the successful run (rcu-good-notime.txt). The failed run is on commit a7d7a143d0b4cb1914705884ca5c25e322dba693 and the successful run has these reverted on top: 187497fa5e9e9383820d33e48b87f8200a747c2a b58cc46c5f6b57f1c814e374dbc47176e6b4938e fbce7497ee5af800a1c350c73f3c3f103cb27a15 That is rcu-bad-notime.txt. > [ 0.000000] Preemptible hierarchical RCU implementation. > [ 0.000000] RCU debugfs-based tracing is enabled. > [ 0.000000] RCU lockdep checking is enabled. > [ 0.000000] Additional per-CPU info printed with stalls. > [ 0.000000] RCU restricting CPUs from NR_CPUS=4 to nr_cpu_ids=1. > [ 0.000000] Offload RCU callbacks from all CPUs > [ 0.000000] Offload RCU callbacks from CPUs: 0. > [ 0.000000] RCU: Adjusting geometry for rcu_fanout_leaf=16, nr_cpu_ids=1 > [ 0.000000] NO_HZ: Full dynticks CPUs: 1-3. > > But NO_HZ thinks that there are four.

Are you running > this on a non-x86_64 CPU so that qemu only does UP or some such? No; this is "Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz" on a ThinkPad T420s. In my attached boot logs, RCU does detect two cpus. Here's the diff between them. I recompiled to remove the timing info so the diffs are comparable: $ diff -u /var/tmp/rcu-bad-notime.txt /var/tmp/rcu-good-notime.txt --- /var/tmp/rcu-bad-notime.txt 2014-08-08 22:49:37.207745682 +0530 +++ /var/tmp/rcu-good-notime.txt 2014-08-08 22:49:04.886653844 +0530 @@ -1,6 +1,6 @@ $ ./x86_64-softmmu/qemu-system-x86_64 -m 512 -smp 2 -cpu host,+kvmclock,+x2apic -enable-kvm -kernel ~/src/linux/arch/x86/boot/bzImage /guests/f11-auto.qcow2 -append 'root=/dev/sda2 console=ttyS0 console=tty0' -snapshot -serial stdio Initializing cgroup subsys cpu -Linux version 3.16.0+ (amit@grmbl.mre) (gcc version 4.8.3 20140624 (Red Hat 4.8.3-1) (GCC) ) #79 SMP PREEMPT Fri Aug 8 22:47:38 IST 2014 +Linux version 3.16.0+ (amit@grmbl.mre) (gcc version 4.8.3 20140624 (Red Hat 4.8.3-1) (GCC) ) #78 SMP PREEMPT Fri Aug 8 22:46:28 IST 2014 Command line: root=/dev/sda2 console=ttyS0 console=tty0 e820: BIOS-provided physical RAM map: BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable @@ -60,7 +60,7 @@ e820: [mem 0x20000000-0xfeffbfff] available for PCI devices Booting paravirtualized kernel on KVM setup_percpu: NR_CPUS:4 nr_cpumask_bits:4 nr_cpu_ids:2 nr_node_ids:1 -PERCPU: Embedded 475 pages/cpu @ffff88001f800000 s1916544 r8192 d20864 u2097152 +PERCPU: Embedded 475 pages/cpu @ffff88001f800000 s1915904 r8192 d21504 u2097152 KVM setup async PF for cpu 0 kvm-stealtime: cpu 0, msr 1f80cbc0 Built 1 zonelists in Zone order, mobility grouping on.

And so what sorts of diagnostics work for you in the hung state? Are you able to dump ftrace buffers? If you are able to dump ftrace buffers, please enable rcu:rcu_nocb_wake and send me the resulting trace. Thanx, Paul ^ permalink raw reply [flat|nested] 48+ messages in thread

Last time, it was qemu losing the wakeups, but maybe it is RCU this time. ;-) Thanx, Paul > --- /var/tmp/rcu-bad.txt 2014-08-11 12:39:53.571306488 +0530 > +++ /var/tmp/rcu-good-nocb-poll.txt 2014-08-11 12:40:37.760432052 +0530 > @@ -1,7 +1,7 @@ > -$ qemu-kvm -m 512 -smp 1 -cpu host,+kvmclock,+x2apic -enable-kvm -kernel ~/src/linux/arch/x86/boot/bzImage /guests/f11-auto.qcow2 -append 'root=/dev/sda2 acpi=off console=ttyS0 console=tty0' -snapshot -serial stdio > +$ qemu-kvm -m 512 -smp 1 -cpu host,+kvmclock,+x2apic -enable-kvm -kernel ~/src/linux/arch/x86/boot/bzImage /guests/f11-auto.qcow2 -append 'root=/dev/sda2 acpi=off console=ttyS0 console=tty0 rcu_nocb_poll' -snapshot -serial stdio > Initializing cgroup subsys cpu > Linux version 3.16.0+ (amit@grmbl.mre) (gcc version 4.8.3 20140624 (Red Hat 4.8.3-1) (GCC) ) #80 SMP PREEMPT Fri Aug 8 22:57:35 IST 2014 > -Command line: root=/dev/sda2 acpi=off console=ttyS0 console=tty0 > +Command line: root=/dev/sda2 acpi=off console=ttyS0 console=tty0 rcu_nocb_poll > e820: BIOS-provided physical RAM map: > BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable > BIOS-e820: [mem 0x000000000009fc00-0x000000000009ffff] reserved > @@ -47,14 +47,14 @@ > KVM setup async PF for cpu 0 > kvm-stealtime: cpu 0, msr 1fa0cbc0 > Built 1 zonelists in Zone order, mobility grouping on.

I can perhaps try getting the trace output out from a virtio-serial channel; but even that driver isn't probed yet when the lockup happens.

First boot with the kernel parameter "trace_event=rcu:rcu_nocb_wake". Then when the system hangs, do "sendkey alt-sysrq-z" at the "(qemu)" prompt to dump the ftrace buffer. This hopefully dumps the trace buffer to dmesg. In addition "sendkey alt-sysrq-t" at the "(qemu)" prompt dumps all tasks' stacks, which would also likely be useful information.

Nah, this doesn't work -- the guest's totally locked up. I need a way to continuously dump buffers till the lockup happens, I suppose. Amit ^ permalink raw reply [flat|nested] 48+ messages in thread

I am assuming that your kernel was built with CONFIG_MAGIC_SYSRQ=y. If all of that is in place and no joy, is it possible to extract the ftrace buffer from the running/hung guest? It should be in there somewhere! ;-) Thanx, Paul ^ permalink raw reply [flat|nested] 48+ messages in thread

The userspace that the qemu is running in might. There is a way to extract ftrace info from crash dumps, so one approach would be "sendkey alt-sysrq-c", then pull the buffer from the resulting dump. For all I know, there might also be some script that uses the qemu "x" command to get at the ftrace buffer. Again, I cannot reproduce this, and I have been through the code several times over the past few days, and am not seeing it. I could start sending you random diagnostic patches, but it would be much better if we could get the trace data from the failure.

This one is theoretically possible, but not on any system that has a full barrier on lock acquisition. This code did not exist before the patch you located via bisection, but on the other hand, given that you were running only two CPUs, it should be dead code anyway. But who knows?

The data exists in the qemu guest state, so it would be good to have it one way or another. My current (perhaps self-serving) guess is that you have come up with a way to trick qemu into dropping IPIs. > > > Hearing no objections, random patch #1.

I am not at all surprised. You would have to have an extremely malevolent compiler for two of them to have any effect, and you would have to have someone invoking call_rcu() with irqs disabled from idle for the other to have any effect. Which is why I missed seeing them the first three times I reviewed this code over the past few days. > My gcc is gcc-4.8.3-1.fc20.x86_64.

My current (perhaps self-serving) guess is that > you have come up with a way to trick qemu into dropping IPIs. Oh, and I wrote up my last inspection of the nocb code. Please see below. Thanx, Paul ------------------------------------------------------------------------ Given that specifying rcu_nocb_poll avoids the hang, the natural focus is on checks for rcu_nocb_poll: o __call_rcu_nocb_enqueue() skips the wakeup if rcu_nocb_poll, which is legitimate because the rcuo kthreads do their own wakeups in this case. o nocb_leader_wait() does wait_event_interruptible() on my_rdp->nocb_leader_wake if !rcu_nocb_poll. So one further question is the handling of ->nocb_leader_wake. The thing to check for is if ->nocb_leader_wake can get set to true without a wakeup while the leader sleeps, as this would clearly lead to a hang. Checking each use: o wake_nocb_leader() tests ->nocb_leader_wake, and if false, sets it and does a wakeup. The set is ordered after the test due to control dependencies. Multiple followers might concurrently attempt to wake their leader, and this can result in multiple wakeups, which should be OK -- we only need one wakeup, so more won't hurt. Here, every time ->nocb_leader_wake is set, we follow up with a wakeup, so this particular use avoids the sleep-while-set problem. It is also important to note that o nocb_leader_wait() waits for ->nocb_leader_wake, as noted above. o nocb_leader_wait() checks for spurious wakeups, but before sleeping again, it clears ->nocb_leader_wake, does a memory barrier, and rescans the callback queues, and sets ->nocb_leader_wake if any have callbacks. Either way, it goes to wait again. If it set ->nocb_leader_wake, then the wait won't wait, as required. The check for spurious wakeups also moves callbacks to an intermediate list for the grace-period-wait operation. This ensures that we don't prematurely invoke any callbacks that arrive while the grace period is in progress. o If the wakeup was real, nocb_leader_wait() clears ->nocb_leader_wake, does a memory barrier, and moves callbacks from the intermediate lists to the followers' lists (including itself, as a leader is its own first follower). During this move, the leader checks for new callbacks having arrived during the grace period, and sets ->nocb_leader_wake if there are any, again short-circuiting the following wake. o Note that nocb_leader_wait() never sets ->nocb_leader_wake unless it has found callbacks waiting for it, and that setting ->nocb_leader_wake short-circuits the next wait, so that a wakeup is not required. Note also that every time nocb_leader_wait() clears ->nocb_leader_wake, it does a memory barrier and scans all the lists before sleeping again. This means that if a wakeup arrives just before nocb_leader_wait() clears ->nocb_leader_wake, then nocb_leader_wait() will be guaranteed to see the newly arrived callback, and thus not need a wakeup. o Because nocb_leader_wait() always checks the queue head, it is necessary that the callers of wake_nocb_leader() ensure that the head is updated before the call to wake_nocb_leader(). This is a problem, and smp_mb__after_atomic() is added after the atomic_add_long() in __call_rcu_nocb_enqueue() to fix this. Note that atomic_add_long() does not have a barrier() directive, so this misordering could in theory happen even on strongly-ordered systems, courtesy of the compiler. o The leader-follower wakeups also need attention, as it references rcu_nocb_poll. nocb_follower_wait() does a wait on rdp->nocb_follower_head, and ensures ordering with the later smp_load_acquire() from that same variable. The wakeup happens in nocb_leader_wait(). This has the same sequence as __call_rcu_nocb_enqueue(), but there is no _wake flag. This means that the only way that confusion could result is if the assignment to *tail was moved to after the wake_up(). Now, wake_up() unconditionally acquires a lock, but in theory only guarantees that stuff before the lock acquisition happens before the lock release. So might as well also add smp_mb__after_atomic here, also. (This will not affect x86, which has strong ordering on lock acquisition.) o Check use of do_nocb_deferred_wakeup(). If any of these has been omitted, then a wakeup could be lost. This is invoked on next entry to an extended quiescent state and on exit from __rcu_process_callbacks(). It is checked on every scheduling-clock interrupt via rcu_nocb_need_deferred_wakeup(), and if needed, an RCU_SOFTIRQ is issued, which will result in a later invocation of __rcu_process_callbacks(). So the only vulnerability is a call_rcu() with irqs disabled from idle. This needs a check. Note that there is a similar check in __call_rcu_core(), though not for irqs disabled. Check added. ^ permalink raw reply [flat|nested] 48+ messages in thread

I am adding nastier rcutorture testing, however. It would still be very good to get debug information from your setup.

I added a few printks on the lines of the traces in cases where rcu_nocb_poll was checked -- since that reproduces the hang. Are the following traces sufficient, or should I keep adding more printks? In the case of rcu-trace-nopoll.txt, the messages stop after a while (when the guest locks up hard). That's when I kill the qemu process.

My guess is that the lockup is caused by indefinite blocking, in which case we would expect all the CPUs to be in the idle loop. Of course, this all assumes that your system is using ACPI for idle.

Hm, found it: The stall happens in do_initcalls(). pm_sysrq_init() is the function that causes the hang. When I #if 0 the line register_sysrq_key('o', &sysrq_poweroff_op); in pm_sysrq_init(), the boot proceeds normally.

Yow!!! > Now what this is, and what relation this has to rcu and that patch in > particular is next... Hmmm... Please try replacing the synchronize_rcu() in __sysrq_swap_key_ops() with (say) schedule_timeout_interruptible(HZ / 10). I bet that gets rid of the hang. (And also introduces a low-probability bug, but should be OK for testing.) The other thing to try is to revert your patch that turned my event traces into printk()s, then put an ftrace_dump(DUMP_ALL); just after the synchronize_rcu() -- that might make it so that the ftrace data actually gets dumped out.

And one other thing to try... Put a printk at the beginning of rcu_spawn_gp_kthread(), which is in kernel/rcu/tree.c. If that printk does not appear before the call to pm_sysrq_init(), that would be an important clue. Thanx, Paul ^ permalink raw reply [flat|nested] 48+ messages in thread
