With 2.6.38-rc3+, I'm receiving nasty WARNINGS and lockdep spews on my
laptop.  Other than the noise, things seem to work fine.  The lockdep
warning is spewed as soon as the second of the following two events
occurs (in any order):

  * a key on the keyboard is pressed.
  * the radio switch is in the off position.

For example, pressing a key after booting with the switch in the off
position will trigger a dump.  The following output was what I got when I
booted with the switch on, flipped the switch off, flipped the switch
back on, then pressed a key (note that the iwlagn errors are normal).
Bisection results follow the traces -- reverting the implicated commit
solves the issue.

1118e2cd33d47254854e1ba3ba8e32802ff14fdf is the first bad commit
commit 1118e2cd33d47254854e1ba3ba8e32802ff14fdf
Author: Yong Zhang <yong.zhang@windriver.com>
Date:   Wed Oct 20 15:57:32 2010 -0700

    timer: Del_timer_sync() can be used in softirq context
    
    Actually we have used del_timer_sync() in softirq context for a long time,
    e.g. in __dst_free()::cancel_delayed_work().
    
    So change the comments of it to warn on hardirq context only, and make
    lockdep know about this change.

The cause is that local_bh_enable() could call do_softirq()
in certain time, thus break irq status and make lock bite
us.

_why_ are you doing the raw_local_irq stuff? That's just weird, and that
comment isn't helping.

Also, calling _local_bh_enable() will leave pending softirqs, not
particularly nice

Just to avoid trigger WARN_ON_ONCE(!irqs_disabled()) in __local_bh_enable(),

Ah, indeed. That's bad.

Now I'm not sure how to work around this issue, because local_bh_enable()
and _local_bh_enable() are not suitable here.

Maybe we can introduce another type of local_bh_enable() in which
waking up ksoftirqd is forced if needed.

Thanks,
Yong

How about we revert your patch and go back to not allowing
del_timer_sync() from any interrupt context, we can fix __dst_free by
removing the need for cancel_delayed_work().

Are there any other del_timer_sync() callers from softirq?

The fact is there is someone want to use del_timer_sync()
in softirq context.
My patch is inspired by this http://lkml.org/lkml/2010/8/16/291
though in the end that issue is resolved by not using
del_timer_sync() in softirq.

I'm not sure about this.

IMHO, we don't need to make more restriction if we don't
have to.

Thanks,
Yong

Right, so that splat warns about:

spin_lock_irqsave(&shost->host_lock);
del_timer_sync()
  spin_lock_irqsave(&t->split_timeout_timer);

vs

<SOFTIRQ>
  call_timer_fn()
    spin_lock(&t->split_timeout_timer);
    <IRQ>
      spin_lock_irqsave(&shost->host_lock);

Which Steven just pointed out is an actual deadlock because:


CPU0					CPU1
spin_lock_irqsave(&shost->host_lock);
					<SOFTIRQ>
					  call_timer_fn();
					    base->running_timer = timer;
					    func();
					      <IRQ>
						spin_lock(&shost->host_lock);
del_timer_sync()
  while(base->running_timer == timer);

And the world stops turning..


Also note that your patch changes the above to:

spin_lock_irqsave(&shost->host_lock);
del_timer_sync()
  spin_lock_bh(&t->split_timeout_timer);

Which wouldn't make one bit of difference.

Twice I had to explain the output about why lockdep gives an error with
locks in IRQ context and with del_timer_sync(). Might as well write it
up and place it in the comments above the code in del_timer_sync().
Perhaps the next time this lockdep dump triggers people will understand
the issues.

It is a ticky issue and very subtle, explaining it in detail in the code
may help others understand the issue when they stumble upon the bug
again.

Subject: [PATCH 1/2] softirq: introduce loacal_bh_enable_force_wake()

If there is pending softirq, don't handle it in the caller's
context, invoke ksoftirqd directly instead.

del_timer_sync() will be the first caller.

The cause is that local_bh_enable() could call do_softirq()
in certain time, thus break irq status and make lock bite
us.

No travel or cyclone-dodging this time, so as promised, the -rc's are
now back to the usual weekly schedule.

There's nothing much that stands out here. Some arch updates (arm and
powerpc), the usual driver updates: dri (radeon/i915), network cards,
sound, media, scisi, some filesystem updates (cifs, btrfs), and some
random stuff to round it all out (networking, watchpoints,
tracepoints, etc).

Pretty small, all in all. I'd obviously prefer it to be even smaller,
and I actually dropped a pull request or two, but for being -rc4 this
is by no means horrible. As long as it keeps shrinking, I'll be happy.

So, I'm getting the warning below early in the boot process. And yes, I
didn't have it on -rc3. 2.6.38-rc4-00001-g1e554e3-dirty means a debug
diff ontop of -rc4 which shouldn't have anything to do with this splat
since all it does is a couple of printk's due to -rc3 not suspending to
disk properly in some cases.

Now, I'm not going to even pretend to understand the code but here's
what I can read out, you tell me whether it makes sense.

spawn_ksoftirqd() is one of the early initcalls that gets called and
it's notifier callback does kthread_bind() and you can follow in the
backtrace below that this thing comes down to del_timer_sync() which
does the lockdep annotation. Now, problem as I see it, is that hardirqs
were disabled when we were called although it doesn't say so in the
irqtrace events dump after the calltrace: "hardirqs last enabled at
(999)" and our irq event stamp is 1000.

There are actually at least three del_timer_sync()'s inflight so the
problem could be there somewhere, I dunno.

So, is it a wrong lockdep annotation or is it a real problem? I've
attached dmesg and config.

Thanks.

Argh! Its an annotation nightmare that.. it didn't trigger for me when
running that because I didn't have DEBUG_LOCKDEP=y.

OK, let me try and come up with another way to annotate this
del_timer_sync() muck, the trouble is we want that lock to be called
with BH disabled, but simply doing local_bh_disable()/local_bh_enable()
has the nasty side effect of calling __do_softirq(). Faking IRQ state
will trip this check_flags() debug muck..

We used to have local_irq_disable()/local_irq_enable() around it, but
then people wanted to use del_timer_sync() from softirq context..

Is my previous patch acceptable?

I inlined it as below(and updated based on linux-2.6.38-rc4)

From: Yong Zhang <yong.zhang0@gmail.com>
Subject: [PATCH 1/2] softirq: introduce loacal_bh_enable_force_wake()

If there is pending softirq, don't handle it in the caller's
context, invoke ksoftirqd directly instead.

del_timer_sync() will be the first caller.

Subject: [PATCH 2/2] timer: use local_bh_enable_force_wake() in del_timer_sync()

raw_local_irq_save()/raw_local_irq_restore() is also not suitable
here because lockdep will report "possible reason: unannotated irqs-off"

To cure this issue, use local_bh_enable_force_wake() here in case of
we have pending softirq left during this time.
