Consider, another task already went to the slow path and is about to wake this task. This task wakes on timeout and subsequently enables static branch again. Now we can have 2 tasks on the slow path that both will wake this task. How will it be handled?

Can it lead to some > warnings or something? wake_up() does not require tasks to be in the wait queue, nor is there any requirement that it's exclusive (it takes the appropriate locks unlike wake_up_locked()). One of the wake_up() calls will wake the task, and the other is a noop. So this will work just fine. Thanks, -- Marco

The fact that it passes on next-20201105 but not on 20201110 is strange. If you boot with KFENCE disabled (boot param kfence.sample_interval=0), does it boot? In your log [2] I see a number of "BUG: workqueue lockup ..." but that doesn't make sense, at least I don't think the KFENCE work item is causing this. It'd be interesting to bisect what changed between 20201105 and 20201110, but I have a suspicion that might take too long. Short of that, let me see if there are any changes between the 2 that look like it might be causing this. Thanks, -- Marco

The fact that it passes on next-20201105 but not > on 20201110 is strange. If you boot with KFENCE disabled (boot param > kfence.sample_interval=0), does it boot?

To me it looks like KFENCE's timer helps uncover a new problem, but trying to work around this new problem in KFENCE seems wrong for now. We need to understand why these "BUG: workqueue lockup" warnings are there. I Cc'd a bunch of folks in that other email that might be able to help. Thanks, -- Marco

The above line says it all from an RCU viewpoint. The rcu_preempt kthread tried to wait for a few jiffies (as in three or fewer), and more than 5000 jiffies later has failed to make any useful forward progress.

The fact that _raw_spin_lcok_irq() last enabled interrupts might mean that RCU is invoking something that used to be OK with having interrupts disabled, but now expects them to be enabled, and thus blindly re-enables them. Or Steven is right, and I should look at the RCU CPU stall-warning code. Still, something bad happened before we got here. Thanx, Paul > | [...] > > Full log and config attached.

Thanx, Paul ------------------------------------------------------------------------ commit c583bcb8f5edd48c1798798e341f78afb9bf4f6f Author: Paul E. McKenney <paulmck@kernel.org> Date: Thu Sep 24 15:11:55 2020 -0700 rcu: Don't invoke try_invoke_on_locked_down_task() with irqs disabled The try_invoke_on_locked_down_task() function requires that interrupts be enabled, but it is called with interrupts disabled from rcu_print_task_stall(), resulting in an "IRQs not enabled as expected" diagnostic. This commit therefore updates rcu_print_task_stall() to accumulate a list of the first few tasks while holding the current leaf rcu_node structure's ->lock, then releases that lock and only then uses try_invoke_on_locked_down_task() to attempt to obtain per-task detailed information. Of course, as soon as ->lock is released, the task might exit, so the get_task_struct() function is used to prevent the task structure from going away in the meantime.

Hey, I had to ask! The only uncertainty I seee is the acquisition of the lock in rcu_iw_handler(), for which I add a lockdep check in the (untested) patch below. The other thing I could do is sprinkle such checks through the stall-warning code on the assumption that something RCU is calling is enabling interrupts. Other thoughts?

Fun. These have been passing quite a bit of rcutorture over here, including preemptible kernels running !SMP, but admittedly on x86 rather than ARMv8. One approach would be to binary-search the combinations of merges. Except that there are six of them, so there are 64 combinations, of which you have tested only 8 thus far (none, one each, and all). But are you sure that the bisection points labeled "good" really are good? For example, what is the distribution of first failure times in the points labeled "bad" vs. the runtime used to make a "good" determination? Alternatively, just try a longer run on each of the commits feeding into the merge point. > > > Failing that, please see the updated patch below.

Was the system responsive at this point, between three and ten minutes after boot? Similar question for the other gaps in the dmesg log. The reason for the question is that workqueue's reported stall times don't span these intervals. > | [ 334.160218] BUG: workqueue lockup - pool cpus=0 node=0 flags=0x0 nice=0 stuck for 15s! It might be instructive to cause this code to provoke a backtrace. I suggest adding something like "trigger_single_cpu_backtrace(cpu)" in kernel/workqueue.c's function named wq_watchdog_timer_fn() somewhere within its "if" statement that is preceded with the "did we stall?" comment. Or just search for "BUG: workqueue lockup - pool" within kernel/workqueue.c. > | [ 334.259490] Showing busy workqueues and worker pools: > | [ 334.265398] workqueue events: flags=0x0 > | [ 334.289070] pwq 0: cpus=0 node=0 flags=0x0 nice=0 active=1/256 refcnt=2 > | [ 334.300659] pending: vmstat_shepherd > | [ 453.541827] BUG: workqueue lockup - pool cpus=0 node=0 flags=0x0 nice=0 stuck for 10s!

Yeah, I'm having doubts, and this might be even more non-deterministic that I thought and some 'good' could maybe be 'bad' if I had re-run them? I don't know. One thing I can try is to make sure I run it more than once, but I'm definitely not doing that manually, so let me try and script something so I don't have to hand-hold the bisection overnight. :-) > > > > Failing that, please see the updated patch below.

It is acting like a self-deadlock or similar hang, except that in that case, lockdep should have complained before the RCU CPU stall warning rather than after. The only thing I can suggest is sprinkling lockdep_assert_irqs_disabled() calls hither and yon. All of the code that lockdep is complaining about runs in the context of the scheduling-clock interrupt, so interrupts had jolly well be disabled! ;-) Rerunning some of the allegedly good bisects might be more productive.

Oof, so I reran bisection, and this time confirming 3x each good run.

So my guess is this probably had existed before, but something in -next is making it more visible. Short of giving up, I can try your suggestion of sprinkling lockdep_assert_irqs_disabled() everywhere, or if you have a patch to apply that would give some other debug output you wanted I can run that too.

I don't have a patch, but if you are still seeing lots of workqueue lockups before the RCU CPU stall warning, I again suggest adding the backtrace as called out in my earlier email. The idea here is to see what is causing these lockups. I can send a formal patch for this if you wish, but today is crazy, so I cannot promise it before this evening, Pacific Time. Thanx, Paul

Not sure if that helps though. In that case, whatever was blocking things should be on the stack on the one hand, or we should have just now returned from an interrupt on the other.

Of course, there might have been an immediately preceding interrupt (or series of interrupts) that took too long. The 10-millisecond interrupt called out above is nowhere near long enough to make this happen. > | preempt_latency_stop kernel/sched/core.c:4197 [inline] > | preempt_latency_stop kernel/sched/core.c:4194 [inline] > | preempt_schedule_common+0xf8/0x1a8 kernel/sched/core.c:4682 > | preempt_schedule+0x38/0x40 kernel/sched/core.c:4706 > | __raw_spin_unlock_irqrestore include/linux/spinlock_api_smp.h:161 [inline] > | _raw_spin_unlock_irqrestore+0x90/0xa0 kernel/locking/spinlock.c:191 > | spin_unlock_irqrestore include/linux/spinlock.h:409 [inline] > | finish_wait+0x78/0xa0 kernel/sched/wait.c:382 The above is waking up in the while-loop in kcompactd(). You are (or at least were) running CONFIG_PREEMPT=y, so the lack of cond_resched() calls should not be affecting you. But it would be good to get the kcompactd() people to look at this (not immediately seeing who they are in MAINTAINERS). Perhaps preemption is disabled somehow and I am failing to see it. Failing that, maybe someone knows of a way to check for overly long timeout handlers.

I think I figured out one piece of the puzzle. Bisection keeps pointing me at some -rcu merge commit, which kept throwing me off. Nor did it help that reproduction is a bit flaky. However, I think there are 2 independent problems, but the manifestation of 1 problem triggers the 2nd problem: 1. problem: slowed forward progress (workqueue lockup / RCU stall reports) 2. problem: DEADLOCK which causes complete system lockup | ... | CPU0 | ---- | lock(rcu_node_0); | <Interrupt> | lock(rcu_node_0); | | *** DEADLOCK *** | | 1 lock held by event_benchmark/105: | #0: ffffbb6e0b804458 (rcu_node_0){?.-.}-{2:2}, at: print_other_cpu_stall kernel/rcu/tree_stall.h:493 [inline] | #0: ffffbb6e0b804458 (rcu_node_0){?.-.}-{2:2}, at: check_cpu_stall kernel/rcu/tree_stall.h:652 [inline] | #0: ffffbb6e0b804458 (rcu_node_0){?.-.}-{2:2}, at: rcu_pending kernel/rcu/tree.c:3752 [inline] | #0: ffffbb6e0b804458 (rcu_node_0){?.-.}-{2:2}, at: rcu_sched_clock_irq+0x428/0xd40 kernel/rcu/tree.c:2581 | ... Problem 2 can with reasonable confidence (5 trials) be fixed by reverting: rcu: Don't invoke try_invoke_on_locked_down_task() with irqs disabled At which point the system always boots to user space -- albeit with a bunch of warnings still (attached). The supposed "good" version doesn't end up with all those warnings deterministically, so I couldn't say if the warnings are expected due to recent changes or not (Arm64 QEMU emulation, 1 CPU, and lots of debugging tools on).

Thanx, Paul ------------------------------------------------------------------------ commit 444ef3bbd0f243b912fdfd51f326704f8ee872bf Author: Peter Zijlstra <peterz@infradead.org> Date: Sat Aug 29 10:22:24 2020 -0700 sched/core: Allow try_invoke_on_locked_down_task() with irqs disabled The try_invoke_on_locked_down_task() function currently requires that interrupts be enabled, but it is called with interrupts disabled from rcu_print_task_stall(), resulting in an "IRQs not enabled as expected" diagnostic. This commit therefore updates try_invoke_on_locked_down_task() to use raw_spin_lock_irqsave() instead of raw_spin_lock_irq(), thus allowing use from either context.

That seems to have the same result (same test setup) as only reverting "rcu: Don't invoke..." does: still results in a bunch of workqueue lockup warnings and RCU stall warnings, but boots to user space. I attached a log. If the warnings are expected (are they?), then it looks fine to me. (And just in case: with "rcu: Don't invoke..." and "sched/core: Allow..." both applied I still get DEADLOCKs -- but that's probably expected.)

This usually happens because the RCU grace-period kthread (named "rcu_preempt" in your case, but can also be named "rcu_sched") is being prevented from running, but can be caused by other things as well. > Modules linked in: > CPU: 0 PID: 1 Comm: swapper/0 Not tainted 5.10.0-rc3-next-20201110-00003-g920304642405-dirty #30 > Hardware name: linux,dummy-virt (DT) > pstate: 20000085 (nzCv daIf -PAN -UAO -TCO BTYPE=--) > pc : rcu_check_gp_start_stall kernel/rcu/tree_stall.h:750 [inline] > pc : rcu_check_gp_start_stall.isra.0+0x14c/0x210 kernel/rcu/tree_stall.h:711 > lr : __xchg_mb arch/arm64/include/asm/cmpxchg.h:88 [inline] > lr : atomic_xchg include/asm-generic/atomic-instrumented.h:615 [inline] > lr : rcu_check_gp_start_stall kernel/rcu/tree_stall.h:751 [inline] > lr : rcu_check_gp_start_stall.isra.0+0x148/0x210 kernel/rcu/tree_stall.h:711 Two program counters and four link registers?

Awesome! ;-) Ah I'm using syzkaller's symbolizer, which duplicates lines if there was an inline function (remove all the "[inline]" and it should make sense, but the "[inline]" tell you the actual line).

But we'd need some selection of suspicious commits. The report claims that one of the rcu_node ->lock fields is held with interrupts enabled, which would indeed be bad. Except that all of the stack traces that it shows have these locks held within the scheduling-clock interrupt handler. Now with the "rcu: Don't invoke try_invoke_on_locked_down_task() with irqs disabled" but without the "sched/core: Allow try_invoke_on_locked_down_task() with irqs disabled" commit, I understand why. With both, I don't see how this happens. At this point, I am reduced to adding lockdep_assert_irqs_disabled() calls at various points in that code, as shown in the patch below. At this point, I would guess that your first priority would be the initial bug rather than this following issue, but you never know, this might well help diagnose the initial bug. Thanx, Paul ------------------------------------------------------------------------ commit ccedf00693ef60f7c06d23490fc41bb60dd43dc3 Author: Paul E. McKenney <paulmck@kernel.org> Date: Thu Nov 19 10:13:06 2020 -0800 rcu: Add lockdep_assert_irqs_disabled() to rcu_sched_clock_irq() and callees This commit adds a number of lockdep_assert_irqs_disabled() calls to rcu_sched_clock_irq() and a number of the functions that it calls. The point of this is to help track down a situation where lockdep appears to be insisting that interrupts are enabled within these functions, which should only ever be invoked from the scheduling-clock interrupt handler.

With both, I don't see how this happens. I'm at a loss, but happy to keep bisecting and trying patches. I'm also considering: Is it the compiler? Probably not, I tried 2 versions of GCC. Can we trust lockdep to precisely know IRQ state? I know there's been some recent work around this, but hopefully we're not affected here?

Thanx, Paul ------------------------------------------------------------------------ commit bcca5277df3f24db15e15ccc8b05ecf346d05169 Author: Paul E. McKenney <paulmck@kernel.org> Date: Thu Nov 19 13:30:33 2020 -0800 rcu: Add lockdep_assert_irqs_disabled() to raw_spin_unlock_rcu_node() macros This commit adds a lockdep_assert_irqs_disabled() call to the helper macros that release the rcu_node structure's ->lock, namely to raw_spin_unlock_rcu_node(), raw_spin_unlock_irq_rcu_node() and raw_spin_unlock_irqrestore_rcu_node(). The point of this is to help track down a situation where lockdep appears to be insisting that interrupts are enabled while holding an rcu_node structure's ->lock.

FWIW, arm64 is known broken wrt lockdep and irq tracing atm. Mark has been looking at that and I think he is close to having something workable. Mark -- is there anything Marco and Paul can try out?

I initially traced some issues back to commit: 044d0d6de9f50192 ("lockdep: Only trace IRQ edges") ... and that change of semantic could cause us to miss edges in some cases, but IIUC mostly where we haven't done the right thing in exception entry/return. I don't think my patches address this case yet, but my WIP (currently just fixing user<->kernel transitions) is at: https://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git/log/?h=arm64/irq-fixes I'm looking into the kernel<->kernel transitions now, and I know that we mess up RCU management for a small window around arch_cpu_idle, but it's not immediately clear to me if either of those cases could cause this report. Thanks, Mark.

I found that disabling ftrace for some of kernel/rcu (see below) solved the stalls (and any mention of deadlocks as a side-effect I assume), resulting in successful boot.

I'm currently looking at it. I had been trying to shift things to C for a while, and right now I'm trying to fix the lockdep state tracking, which is requiring untangling lockdep/rcu/tracing. The main issue I see remaining atm is that we don't save/restore the lockdep state over exceptions taken from kernel to kernel. That could result in lockdep thinking IRQs are disabled when they're actually enabled (because code in the nested context might do a save/restore while IRQs are disabled, then return to a context where IRQs are enabled), but AFAICT shouldn't result in the inverse in most cases since the non-NMI handlers all call lockdep_hardirqs_disabled(). I'm at a loss to explaim the rcu vs ftrace bits, so if you have any pointers to the issuies ween with the x86 rework that'd be quite handy.

That is, do you really need all of the above to stop the stalls? Also, since you are using linux-next, you have ftrace recursion debugging. Please enable: CONFIG_FTRACE_RECORD_RECURSION=y CONFIG_RING_BUFFER_RECORD_RECURSION=y when enabling any of the above. If you can get to a successful boot, you can then: # cat /sys/kernel/tracing/recursed_functions Which would let me know if there's an recursion issue in RCU somewhere. -- Steve -- Steve

There were several over a number of months. I especially recall issues with the direct-from-idle execution of smp_call_function*() handlers, and also with some of the special cases in the entry code, for example, reentering the kernel from the kernel. This latter could cause RCU to not be watching when it should have been or vice versa. I would of course be most aware of the issues that impinged on RCU and that were located by rcutorture. This is actually not hard to run, especially if the ARM bits in the scripting have managed to avoid bitrot. The "modprobe rcutorture" approach has fewer dependencies.

Ah; those are precisely the cases I'm currently fixing, so if we're lucky this is an indirect result of one of those rather than a novel source of pain... > I would of course be most aware of the issues that impinged on RCU > and that were located by rcutorture.

Either way: > https://paulmck.livejournal.com/57769.html and later posts. That is a very good idea. I'd been relying on Syzkaller to tickle the issue, but the torture infrastructure is a much better fit for this problem. I hadn't realise how comprehensive the scripting was, thanks for this! I'll see about giving that a go once I have the irq-from-idle cases sorted, as those are very obviously broken if you hack trace_hardirqs_{on,off}() to check that RCU is watching. Thanks, Mark.

To get the system to boot in the first place (as mentioned in other emails) I again needed to revert "rcu: Don't invoke try_invoke_on_locked_down_task() with irqs disabled", as otherwise would run into the deadlock. That used to still result in stall warnings, except when ftrace's recursion detection is on it seems.

They happen when an interrupt occurs while tracing something with interrupts enabled, and the interrupt traces a function before it sets the "preempt_count" to reflect that its in a new context. That is: normal_context: func_A(); trace_function(); <interrupt> irq_enter(); trace_function() if (int_interrupt()) [returns false] set_preempt_count (in interrupt) And the recursion detection is tricked into thinking it recursed in the same context. The lastest code handles this by allowing one level of recursion: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=b02414c8f045ab3b9afc816c3735bc98c5c3d262 -- Steve

And it probably is the issue because that thread will never sleep! It runs a loop of: static int benchmark_event_kthread(void *arg) { /* sleep a bit to make sure the tracepoint gets activated */ msleep(100); while (!kthread_should_stop()) { trace_do_benchmark(); /* * We don't go to sleep, but let others run as well. * This is basically a "yield()" to let any task that * wants to run, schedule in, but if the CPU is idle, * we'll keep burning cycles. * * Note the tasks_rcu_qs() version of cond_resched() will * notify synchronize_rcu_tasks() that this thread has * passed a quiescent state for rcu_tasks.

I noticed that you have PREEMPT enabled so this will only be preempted when its schedule time runs out and something else wants to run. How would that affect other threads? -- Steve

If you get a chance, would you mind giving that a spin? The HEAD commit should be: a51334f033f8ee88 ("HACK: check IRQ tracing has RCU watching") Otherwise, I intend to clean that up and post it tomorrow (without the additional debug hacks). I've thrown my local Syzkaller instance at it in the mean time (and if I get the chance tomrrow I'll try to get rcutorture setup), and the only report I'm seeing so far looks genuine: | BUG: sleeping function called from invalid context in sta_info_move_state ... as that was reported on x86 too, per: https://syzkaller.appspot.com/bug?id=6c7899acf008be2ddcddb46a2567c2153193632a Thanks, Mark.

Given this, a possible case cause this is that we got preempted inside a rcu_node lock critical section (I know, this is quite impossible, but preemption count and lockdep data are maintained quite separately, so it's unlikely they are broken at the same time...)

Were these messages accompanied by an RCU CPU stall warning that listed some preempted tasks blocking the current grace period? If so, does this patch in -rcu help? d02133f517e5 ("sched/core: Allow try_invoke_on_locked_down_task() with irqs disabled") Thanx, Paul ------------------------------------------------------------------------ commit d02133f517e5b4eb417ad88b14c0759a0c0deac6 Author: Peter Zijlstra <peterz@infradead.org> Date: Sat Aug 29 10:22:24 2020 -0700 sched/core: Allow try_invoke_on_locked_down_task() with irqs disabled The try_invoke_on_locked_down_task() function currently requires that interrupts be enabled, but it is called with interrupts disabled from rcu_print_task_stall(), resulting in an "IRQs not enabled as expected" diagnostic. This commit therefore updates try_invoke_on_locked_down_task() to use raw_spin_lock_irqsave() instead of raw_spin_lock_irq(), thus allowing use from either context.

Your series appears to work and fixes the stalls and deadlocks (3 trials)! I noticed there are a bunch of warnings in the log that might be relevant (see attached). Note, I also reverted sched/core: Allow try_invoke_on_locked_down_task() with irqs disabled and that still works.

I'm glad that appears to work, as it suggests there's not another massive problem lurking in this area. While cleaning/splitting that up today, I spotted a couple of new problems I introduced, and I'm part-way through sorting that out, but it's not quite ready today after all. :/ Fingers crossed for tomorrow... > I noticed there are a bunch of warnings in the log > that might be relevant (see attached). > [ 91.184432] ============================= > [ 91.188301] WARNING: suspicious RCU usage > [ 91.192316] 5.10.0-rc4-next-20201119-00002-g51c2bf0ac853 #25 Tainted: G W > [ 91.197536] ----------------------------- > [ 91.201431] kernel/trace/trace_preemptirq.c:78 RCU not watching trace_hardirqs_off()! > [ 91.206546] > [ 91.206546] other info that might help us debug this: > [ 91.206546] > [ 91.211790] > [ 91.211790] rcu_scheduler_active = 2, debug_locks = 0 > [ 91.216454] RCU used illegally from extended quiescent state! > [ 91.220890] no locks held by swapper/0/0. > [ 91.224712] > [ 91.224712] stack backtrace: > [ 91.228794] CPU: 0 PID: 0 Comm: swapper/0 Tainted: G W 5.10.0-rc4-next-20201119-00002-g51c2bf0ac853 #25 > [ 91.234877] Hardware name: linux,dummy-virt (DT) > [ 91.239032] Call trace: > [ 91.242587] dump_backtrace+0x0/0x240 > [ 91.246500] show_stack+0x34/0x88 > [ 91.250295] dump_stack+0x140/0x1bc > [ 91.254159] lockdep_rcu_suspicious+0xe4/0xf8 > [ 91.258332] trace_hardirqs_off+0x214/0x330 > [ 91.262462] trace_graph_return+0x1ac/0x1d8 > [ 91.266564] ftrace_return_to_handler+0xa4/0x170 > [ 91.270809] return_to_handler+0x1c/0x38 > [ 91.274826] default_idle_call+0x94/0x38c > [ 91.278869] do_idle+0x240/0x290 > [ 91.282633] rest_init+0x1e8/0x2dc > [ 91.286529] arch_call_rest_init+0x1c/0x28 > [ 91.290585] start_kernel+0x638/0x670 Hmm... I suspect that arch_cpu_idle() is being traced here, and I reckon we have to mark that and its callees as noinstr, since it doesn't seem sane to have ftrace check whether RCU is watching for every function call. Maybe Paul or Steve can correct me. ;) If you still have the binary lying around, can you check whether default_idle_call+0x94/0x38c is just after the call to arch_cpu_idle()? If you could dump the asm around that, along with whatever faddr2line tells you, that'd be a great help. This looks like it should be reproducible, so I'll enable the boot-time self tests in my kernel and check whether I see the above too. Thanks, Mark.

I think this is a latent issue my debug hacks revealed (in addition to a couple of other issues in the idle path), and still affects x86 and others. It's only noticeable if you hack trace_hardirqs_{on,off}() to check rcu_is_watching(), which I had at the tip of my tree. AFAICT, the issue is that arch_cpu_idle() can be dynamically traced with ftrace, and hence the tracing code can unexpectedly run without RCU watching. Since that's dynamic tracing, we can avoid it by marking arch_cpu_idle() and friends as noinstr. I'll see about getting this fixed before we upstream the debug hack. Thanks, Mark.

Technically, ftrace doesn't care if RCU is watching or not, but the callbacks might, and they need to do the rcu_is_watching() check if they do. Although, there's work to keep those areas from being traced, but to do so, they really need to be minimal, where you don't ever want to trace them. -- Steve

To toggle the allocation gates, we set up a delayed work that calls toggle_allocation_gate(). Here we use wait_event() to await an allocation and subsequently disable the static branch again. However, if the kernel has stopped doing allocations entirely, we'd wait indefinitely, and stall the worker task. This may also result in the appropriate warnings if CONFIG_DETECT_HUNG_TASK=y. Therefore, introduce a 1 second timeout and use wait_event_timeout(). If the timeout is reached, the static branch is disabled and a new delayed work is scheduled to try setting up an allocation at a later time. Note that, this scenario is very unlikely during normal workloads once the kernel has booted and user space tasks are running. It can, however, happen during early boot after KFENCE has been enabled, when e.g. running tests that do not result in any allocations.
