[-- Attachment #1: 0001-tracing-use-recursive-counter-over-irq-level.patch --]
[-- Type: text/plain, Size: 2587 bytes --]
From: Steven Rostedt <srostedt@redhat.com>
Althought using the irq level (hardirq_count, softirq_count and in_nmi)
was nice to detect bad recursion right away, but since the counters are
not atomically updated with respect to the interrupts, the function tracer
might trigger the test from an interrupt handler before the hardirq_count
is updated. 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.

From: Steven Rostedt <srostedt@redhat.com>
The startup tests for the event tracer also runs with the function
tracer enabled. The "wakeup" version of the trace commit was used
which can grab spinlocks. If a task was preempted by an NMI
that called a function being traced, it could deadlock due to the
function tracer trying to grab the same lock.
Thanks to Frederic Weisbecker for pointing out where the bug was.

Aah, I was about to push my version, which was the same but with
a more weird changelog :-)

I was going to let you post it, but since I was the one to write the bug,
and it was a one-liner, and I was hitting it myself, I decided to push it.
Otherwise I might have seen your patch's signature section:
fixed-code-f*cked-up-by: Steven Rostedt
/me was reading the conversation on IRC ;-)

Pulled, thanks guys! I've reactivated the self-tests in tip:master -
lets see how it goes today.

The warning means that we wrapped the ring buffer before finishing a
single commit. 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?

commit b76929b6d87e98e49a0988b863debb1a12bcf42b
Author: Steven Rostedt <srostedt@redhat.com>
Date: Tue Apr 21 09:41:26 2009 -0400
ring-buffer: only warn on wrap if buffer is bigger than two pages
On boot up, to save memory, ftrace allocates the minimum buffer
which is two pages. 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.
[ Impact: prevent false WARN_ON in ftrace startup tests ]

The above looks like the tracer slowed things down enough to trigger a
race elsewhere.
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.

Interesting, with your config I hit the bug here. 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. I turned it on and
it booted fine :-/

I spent the entire day (and half the night) debugging this. I was fighting
a case where the hardirqs_enabled flag in the task struct (lockdep flag)
was mysteriously being set and cleared. 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.

It's indeed a tricky one. I can reproduce it too, I will
try to manage having an irqsoff trace at this point, hopefully I
could get the source of this irq disabling...

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.
Thanks,

Yes it is enabled.

Ok I will try it without PARAVIRT and tell you if I can reproduce it.

Interesting. What code is generated for native_irq_enable/disable?

Note, when I take my standard config and enable PARAVIRT and LOCKDEP it
still boots up fine. It may be a combination of some configs :-/
I'm currently doing a "config bisect" to find out what configs are needed.

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.

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 :-/

function tracer was active? So somewhere there we corrupted this
state? It's unlikely that printk itself did this.

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.

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.

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. 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.

ah, so the problem is ftrace doing a function trace entry _in the
middle_ of the raw-irqs section in __native_flush_tlb_global()? (due
to the cr4 getting virtualized too)
Nasty, really nasty.

OK, the good news is that its not a callee-save calling convention
problem, which is what I feared. But it does sound pretty awkward to
fix. Does __native_flush_tlb_global() have to use
raw_local_irq_save/restore?

Vaguely related...makes sense to do native_(read/write)_cr4 since it's
the native tlb flushing implementation, no?
looks ok from inspection, not tested yet...

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.

BTW, Steve, does that fix it for you? Sure makes the code cleaner:

Hi Chris,
I bet it does, but I'm currently reviewing if we need the raw there. I may
take your patch instead.
I'm about to leave for school so I'll look at this later tonight.

btw., you could perhaps use early_printk() - which is a lot less
intrusive. It has no locking nor any irq-flags manipulation. (for
the serial bits at least)

This really demonstrates the cost of paravirt :-/
Please lets not forget this patch - it makes sense regardless of
whether it works around the bug i reported.
