This will trigger a false warning. This patch converts the recursive detection to a simple counter. If the depth is greater than 16 then the recursive detection will trigger. 16 is more than enough for any nested interrupts.

But on start up, we only have two pages. This can easily happen if we do not expand the ring buffer before tracing. This warning does not turn off tracing or disable anything else, because it is perfectly valid to happen, but on large ring buffers it could be a sign of something wrong. Maybe I should only warn if the ring buffer has more than two pages? -- Steve > [ 7.909137] Modules linked in: > [ 7.909137] Pid: 0, comm: swapper Not tainted 2.6.30-rc2-tip #38087 > [ 7.909137] Call Trace: > [ 7.909137] <IRQ> [<ffffffff8025a273>] warn_slowpath+0xca/0x115 > [ 7.909137] [<ffffffff802bf4fe>] ? __rb_reserve_next+0x2a5/0x40c > [ 7.909137] [<ffffffff8021ab74>] ? native_sched_clock+0x4f/0x6a > [ 7.909137] [<ffffffff8021ab74>] ? native_sched_clock+0x4f/0x6a > [ 7.909137] [<ffffffff8021ab74>] ? native_sched_clock+0x4f/0x6a > [ 7.909137] [<ffffffff802bf2c6>] ? __rb_reserve_next+0x6d/0x40c > [ 7.909137] [<ffffffff802cb54e>] ? time_hardirqs_off+0x31/0x47 > [ 7.909137] [<ffffffff802bf389>] __rb_reserve_next+0x130/0x40c > [ 7.909137] [<ffffffff802c00ad>] rb_reserve_next_event+0x1d3/0x31a > [ 7.909137] [<ffffffff802c04c9>] ring_buffer_lock_reserve+0x16b/0x1cb > [ 7.909137] [<ffffffff802c4f4b>] trace_buffer_lock_reserve+0x34/0x7e > [ 7.909137] [<ffffffff802c542c>] trace_vbprintk+0x136/0x275 > [ 7.909137] [<ffffffff8028534f>] ? trace_hardirqs_on_caller+0x132/0x18e > [ 7.909137] [<ffffffff80286cfb>] ? lock_acquire+0x74/0x15b > [ 7.909137] [<ffffffff802ca54b>] __trace_bprintk+0x80/0x9d > [ 7.909137] [<ffffffff802661bc>] ? run_timer_softirq+0x16f/0x281 > [ 7.909137] [<ffffffff802ca54b>] ? __trace_bprintk+0x80/0x9d > [ 7.909137] [<ffffffff80283871>] ? put_lock_stats+0x44/0x5a > [ 7.909137] [<ffffffff802c5d68>] ? tracing_record_cmdline+0x3d/0x141 > [ 7.909137] [<ffffffff802661bc>] ? run_timer_softirq+0x16f/0x281 > [ 7.909137] [<ffffffff8028259c>] ftrace_event_lock_acquire+0x6a/0x89 > [ 7.909137] [<ffffffff80266273>] ? run_timer_softirq+0x226/0x281 > [ 7.909137] [<ffffffff80286cfb>] lock_acquire+0x74/0x15b > [ 7.909137] [<ffffffff80266273>] ? run_timer_softirq+0x226/0x281 > [ 7.909137] [<ffffffff802668c1>] ? process_timeout+0x0/0x37 > [ 7.909137] [<ffffffff80a246af>] _spin_lock_irq+0x5c/0xa5 > [ 7.909137] [<ffffffff80266273>] ? run_timer_softirq+0x226/0x281 > [ 7.909137] [<ffffffff80266273>] run_timer_softirq+0x226/0x281 > [ 7.909137] [<ffffffff802661bc>] ? run_timer_softirq+0x16f/0x281 > [ 7.909137] [<ffffffff802133d6>] ? ftrace_call+0x5/0x2b > [ 7.909137] [<ffffffff80260bd3>] __do_softirq+0xff/0x22c > [ 7.909137] [<ffffffff802149bc>] call_softirq+0x1c/0x30 > [ 7.909137] [<ffffffff802163df>] do_softirq+0x5f/0xdb > [ 7.909137] [<ffffffff802601ac>] irq_exit+0x5d/0x7d > [ 7.909137] [<ffffffff80a2a076>] do_IRQ+0xbe/0xeb > [ 7.909137] [<ffffffff80214153>] ret_from_intr+0x0/0x16 > [ 7.909137] <EOI> [<ffffffff802bf2a9>] ? __rb_reserve_next+0x50/0x40c > [ 7.909137] [<ffffffff802c00ad>] ? rb_reserve_next_event+0x1d3/0x31a > [ 7.909137] [<ffffffff802c00ad>] ? rb_reserve_next_event+0x1d3/0x31a > [ 7.909137] [<ffffffff802c04c9>] ? ring_buffer_lock_reserve+0x16b/0x1cb > [ 7.909137] [<ffffffff802c4f4b>] ? trace_buffer_lock_reserve+0x34/0x7e > [ 7.909137] [<ffffffff8021b722>] ? test_ti_thread_flag+0x8/0x38 > [ 7.909137] [<ffffffff802c5d15>] ? trace_current_buffer_lock_reserve+0x36/0x4c > [ 7.909137] [<ffffffff802d3227>] ? function_test_events_call+0x8f/0x12e > [ 7.909137] [<ffffffff8021b841>] ? need_resched+0x36/0x54 > [ 7.909137] [<ffffffff802d3251>] ? function_test_events_call+0xb9/0x12e > [ 7.909137] [<ffffffff802133d6>] ? ftrace_call+0x5/0x2b > [ 7.909137] [<ffffffff8021b727>] ? test_ti_thread_flag+0xd/0x38 > [ 7.909137] [<ffffffff8021b841>] ? need_resched+0x36/0x54 > [ 7.909137] [<ffffffff8021b945>] ? poll_idle+0x41/0x64 > [ 7.909137] [<ffffffff802cb871>] ? stop_critical_timings+0x3d/0x54 > [ 7.909137] [<ffffffff802127b2>] ? cpu_idle+0xb1/0x112 > [ 7.909137] [<ffffffff809e6369>] ? rest_init+0x8d/0xa3 > [ 7.909137] [<ffffffff8108709a>] ? start_kernel+0x49c/0x4bd > [ 7.909137] [<ffffffff81086140>] ? early_idt_handler+0x0/0x71 > [ 7.909137] [<ffffffff810862ce>] ? x86_64_start_reservations+0xb9/0xd4 > [ 7.909137] [<ffffffff81086000>] ? _sinittext+0x0/0x140 > [ 7.909137] [<ffffffff81086441>] ? x86_64_start_kernel+0x158/0x17b > [ 7.909137] ---[ end trace 3b85485e39bcb7cf ]--- > [ 7.912099] OK > [ 7.913421] initcall event_trace_self_tests_init+0x0/0x5f returned 0 after 233398 usecs > [ 7.914172] calling random32_reseed+0x0/0xce @ 1 > [ 7.915159] initcall random32_reseed+0x0/0xce returned 0 after 0 usecs > [ 7.916145] calling pci_resource_alignment_sysfs_init+0x0/0x40 @ 1 > ^ permalink raw reply [flat|nested] 37+ messages in thread

Ftrace also goes through a series of tests (when configured) on boot up. These tests can fill up a page within a single interrupt. The ring buffer also has a WARN_ON when it detects that the buffer was completely filled within a single commit (other commits are allowed to be nested). Combine the small buffer on start up, with the tests that can fill more than a single page within an interrupt, this can trigger the WARN_ON. This patch makes the WARN_ON only happen when the ring buffer consists of more than two pages.

We have function tracing happening, and here we enabled the sched_kthread_stop tracepoint. Each test starts and stops a kernel thread. I'm not sure how this could have triggered. I'll investigate a little more. -- Steve ^ permalink raw reply [flat|nested] 37+ messages in thread

But it was the hardirqs_enabled that was hit (was that the same you had?) I noticed that you do not have the DEBUG_LOCKDEP set.

Ftrace also goes through a series of tests (when configured) on boot up. These tests can fill up a page within a single interrupt. The ring buffer also has a WARN_ON when it detects that the buffer was completely filled within a single commit (other commits are allowed to be nested). Combine the small buffer on start up, with the tests that can fill more than a single page within an interrupt, this can trigger the WARN_ON. This patch makes the WARN_ON only happen when the ring buffer consists of more than two pages.

I stepped through the entire kernel thread fork process (that was an exercise) and could not find anything wrong. Sometimes it would go away with printk's sometimes it would not. This was driving me crazy, until I noticed that paravirt was enabled. Turning off paravirtualization here (so far) makes everything run smoothly. Thus my theory is that there's something fishy with the modifying of the irq enable/disable code when the system detects that it is running on bare hardware. I'm too tired to look at this more. Ingo supplied a config to play with. You can disable VSMP too and it will still trigger the crash. -- Steve ^ permalink raw reply [flat|nested] 37+ messages in thread

It doesn't disable interrupts :-/ It is the hardirqs_enabled flag in the task struct that mysteriously turns off and back on. I put in printks when it is off in fork, and the next printk shows that it turns back on (between the printks!!!). I printed the output of "irqs_disabled()" on each of these printks and interrupts are always enabled. It is only the hardirqs_enabled flag that is giving strange outputs. Do you have CONFIG_PARAVIRT on? When I disabled it, I have yet to reproduce the bug. But I've only rebooted a few times. I'm going to continue to reboot to see if I can trigger it. I'm thinking that the paravirt alternative code may have clobbered a register in either the enable or disabling of interrupts. This might cause a strange value to go into the hardirqs_enabled flag.

I just finished the config bisect, and it came down to CONFIG_DEBUG_PAGEALLOC (set is bad, not set is good). I'm sure this is not the only config that is at issue. It is probably a combination of configs :-/ I'll try others to see if things change. -- Steve ^ permalink raw reply [flat|nested] 37+ messages in thread

It could also be the timing of an incoming IRQ to hit a particular race window. PAGEALLOC might trigger the right kind of delays to make it trigger.

Ingo supplied a config to play with. > You can disable VSMP too and it will still trigger the crash. > OK, after spending two full days doing a config bisect to find out what is happening, I've found that CONFIG_PARAVIRT and CONFIG_DEBUG_PAGEALLOC do not play nicely. But I have yet to find out why. Here's the situation: We've added selftests for the event tracer. What this basically does is enables each event one at a time and runs tests. The tests include creating a kernel thread, executing workqueues and grabbing locks. We also have PROVE_LOCKING (LOCKDEP) enabled, that keeps track of interrupts being enabled. When they are, we set a flag in the task struct "hardirqs_enabled". When they are disabled, this flag is cleared. When we fork a process, a test is made to see if the flag is set for the new process and if it is not, a warning is printed (as is done in the above dump). I investigated this and found that the flag is mysteriously being set and cleared for no apparent reason. The flag is in the task struct and nothing should be touching it. In fact, it is a full int, not even a bit in a flags variable. I had a test that would print the flag and irqs_disabled() in copy_process before the warning and it showed that the flag was cleared but irqs was enabled. The funny part is, I if the test triggered, I printed the flag again, and the second print it was set again!! if (!p->hardirqs_enabled) { printk("irqs:%d flag:%d\n", irqs_disabled(), p->hardirqs_enabled); printk("try again: %d\n", p->hardirqs_enabled); } The first print showed that it was cleared, the second showed it was set again?? To trigger this I need these config options set: CONFIG_EVENT_TRACING CONFIG_FUNCTION_TRACER CONFIG_PROVE_LOCKING CONFIG_PARAVIRT CONFIG_DEBUG_PAGEALLOC CONFIG_EVENT_TRACING is needed because it does the tests. CONFIG_PROVE_LOCKING is needed because it is the trigger to the WARN_ON (the test for hardirqs_enabled being cleared) CONFIG_FUNCTION_TRACER may be part of the problem, or it just changes the way things work to cause it. CONFIG_PARAVIRT and CONFIG_DEBUG_PAGEALLOC, disable either of them, the problem goes away :-/ Also note, when I did the printks to find where the hardirqs_enabled went zero, it would consistantly happen after this call: ti = alloc_thread_info(tsk); I'll see if I can find exactly where it happens :-/ -- Steve ^ permalink raw reply [flat|nested] 37+ messages in thread

So somewhere there we corrupted this > state? It's unlikely that printk itself did this. The problem always arises at the same spot. I'm not saying printk was the culprit, I'm saying that printk actually "fixed" the issue. Which can be a sign of a corrupted register somewhere. I currently tracked it down to something in "prep_new_page". It is hard to debug because as I add tests into the code, it makes the race window smaller, and I need to run multiple boots to trigger the code. But when I do trigger it (and I try to trigger it a few times) it always happens at the same spot. Note, everytime I catch the issue, the printk again "fixes" the problem :-/ Since I need both DEBUG_PAGEALLOC and PARAVIRT on, I'm thinking that the debug page alloc might be messing with the paravirt "modified" code (or vice versa). It could also be the function tracer doing it too. But it looks like the DEBUG_PAGEALLOC code is causing issues because the bug always appears in the alloc code. I'm not blaming any subsystem yet. It just seems that the combination of these systems are broken. -- Steve ^ permalink raw reply [flat|nested] 37+ messages in thread

It just seems that the combination of > these systems are broken. OK, now I need help :-p I traced the corruption down to the __flush_tlb_all() in kernel_map_pages. This is only called when DEBUG_PAGEALLOC is enabled, thus this explains why DEBUG_PAGEALLOC must be set. Now it may be an issue between the function tracer and paravirt. The __flush_tlb_all is: static inline void __flush_tlb_all(void) { if (cpu_has_pge) __flush_tlb_global(); else __flush_tlb(); } Which, on my box calls __flush_tlb_global() which is a paravirt call: static void native_flush_tlb_global(void) { __native_flush_tlb_global(); } Even though the alternative code makes this a direct call, it is still traced by ftrace. Heck, even the calls in __native_flush_tlb_global call into paravirt (read_cr4 and write_cr4). static inline void __native_flush_tlb_global(void) { unsigned long flags; unsigned long cr4; /* * Read-modify-write to CR4 - protect it from preemption and * from interrupts. (Use the raw variant because this code can * be called from deep inside debugging code.) */ raw_local_irq_save(flags); cr4 = read_cr4(); /* clear PGE */ write_cr4(cr4 & ~X86_CR4_PGE); /* write old PGE again and flush TLBs */ write_cr4(cr4); raw_local_irq_restore(flags); } Each of those read_cr4 and write_cr4 can be traced. But I still do not see how this can cause corruption in the current task struct. The TLB just caches the pages we are using, not the contents inside. I still do not see how this can corrupt a bit.

I > still do not see how this can corrupt a bit. Unless a register leaked :-/ Ah, this is a lockdep thing. The raw_local_irq_save/restore in __native_flush_tlb_global does not update hardirqs_enabled. When we call into ftrace, when we cross page bounderies, we disable interrupts using the normal local_irq_save/restore calls. But when we restore, it detects that interrupts are not going to be enabled, and keeps hardirqs_enabled off. The printk solved the issue because it called local_irq_restore, which set the variable back. I guess there's two solutions here. One, we can change the raw_local_irq_enable/disable variants in __native_flush_tlb_global to the non-raw type (it should protect against recursion). or we can try to make the ring buffer use the raw_local_irq variants too. I tried this once before, and it did cause issues. Note, there's a "check_flags" in lockdep, but it is only called on locking, it is not called when we only disable/enable interrupts. -- Steve ^ permalink raw reply [flat|nested] 37+ messages in thread

No, I just investigated (and booted) without the raw versions (using the normal disable instead). The hooks just update variables in the task struct. I see no reason to have use it. I use to use it with ftrace, but I found that issues are caused if ftrace called something internal that used local_irq_save. Perhaps that is the issue. If something uses raw_local_irq_save then calls flush_tlb_global you might get a problem with the flags again (like we did here). But the only user of raw_* should be lockdep and irqsoff, and they should be able to deal with recursion. I don't think there should be any other user. -- Steve ^ permalink raw reply [flat|nested] 37+ messages in thread
