Hi,
While playing around with netem (time, not packet count based loss-
bursts) I experienced soft lockups several times - to exclude it was my
modifications causing this I recompiled with the original and it is
still locking up.
I captured several of those traces via the thankfully
still working netconsole.
The simplest policy I could reproduce the error with was:
tc qdisc add dev eth0 root handle 1: netem delay 10ms loss 0
I could not reproduce the error without delay - but that may only be a
timing issue, as the host I was mainly transferring data to was on a
local network.
I could not reproduce the issue on lo.
The time to reproduce the error varied from seconds after executing tc
to several minutes.
Traces 5+6 are made with vanilla 52989765629e7d182b4f146050ebba0abf2cb0b7
The earlier traces are made with parts of my patches applied, and only
included for completeness as I don't believe my modifications were
causing this and all traces are different, so it may give some clues.
Lockdep was enabled but did not diagnose anything relevant (one dvb
warning during bootup).
Any ideas for debugging?
Andres
PS: I also could reproduce the issue without netconsole but in vain of a
serial console could not capture a trace.

Maybe these traces will be enough, but lockdep report could save time.
If dvb warning triggers every time then lockdep probably turns off
just after (it works this way, unless something was changed). So,
could you try to repeat this without dvb? Btw., did you try this on
some earlier kernel?

Yes. Today I could not manage to reproduce it on 2.6.30 but could on
current git...
I *think* I could also provoke the same issue on lo, but I am not
completely sure, as the host I was redirecting netconsole to
unfortunately was not up, so I could not check if it was a similar trace.
It could also have been triggered by some random traffic on eth0... Hard
to say.
Will try without dvb.

So I tried - and I did not catch any lockdep output before the crash.
Unfortunately I do not have another machine on the same local network to
catch any messages after the crash... So I could be missing some warning
(I did synchronous logging though).
Will check with netconsole tomorrow.

Could you try if this patch changes anything?

Im getting this one too. On any .31-rc1-gitXX, it pops up a few
seconds after i turn traffic shaping on with tc/htb (no netem here).
Its easily reproducible on my end, turn on traffic shaping, get
traffic flowing, box freezes. No error message, nothing on logs,
although -sometimes- i get lockdep error messages on screen, but
scrolls too fast and box is otherwise unresponsive, so i can't get the
error out.
This does not happen on 2.6.30 at all.
Hope this helps.
(i tried both CONFIG_PACKET_MMAP off and the patch, still happens).

It helps for sure - to save on useless checking, and maybe reproduce
too.
Thank you very much Joao,

Ok. Removed the skb_orphan and turned of CONFIG_PACKET_MMAP. Seemingly
the same game.
I now had another computer to catch the netconsole output. Still no
lockdep warnings.
Unfortunately the other computer was a windows machine with its strange
terminal, so long lines are wrapped at 80cols, but that shouldn't be too
bad.

It's very nice ;-) Alas we can see here only one side, so there is
still some searching needed. I hope I'll be able to reproduce this
later.

I will start trying to place the issue by testing with existing kernels
between 2.6.30 and now.

If you can afford your time of course this would be very helpful.

Well. Waiting for the issue to resolve itself would cost time as well ;-)
I wont be able to finish this today, but perhaps some reduction of the
search space will be enough.
I placed it between 2.6.30 and 03347e2592078a90df818670fddf97a33eec70fb
(v2.6.30-5415-g03347e2) so far.

Ok. I finally see the light. I bisected the issue down to
eea08f32adb3f97553d49a4f79a119833036000a : timers: Logic to move non
pinned timers
Disabling timer migration like provided in the earlier commit stops the issue
from occuring.
That it is related to timers is sensible in the light of my findings, that I
could trigger the issue only when using delay in netem - that is the codepath
using qdisc_watchdog...

Andres, thanks for your work and time. It saved me a lot of searching,
because I wasn't able to trigger this on my old box.

Thanks. It allowed me to go through some of my remaining paperwork ;-)
Does anybody of you have an idea where the problem actually resides?
qdisc_watchdog_schedule looks innocent enough for my uneducated eyes - and the
patch/infrastructure from Arun goes over my head...
I will happily test some ideas/patches.
Aside from that - is the whole PSCHED_TICKS2NS/PSCHED_NS2TICKS conversion
business purely backward compatibility?

The whole PSCHED_ conversion was to get finer resolution without
breaking backward compatibility, I hope.;-)

I have no ideas how/if the timers are actually broken or if the problem does
reside somewhere else and is just made visible by the timer changes.
I would have expected more problem with completely borked timers ;-)

Well, if you look at that commit the bisect pointed to Jarek, it is a
change which starts causing a situation which never happened before.
Namely, timers added on one cpu can be migrated and fire on another.
So this could be exposing races in the networking that technically
always existed.

I'm not sure I get your point; could you give some example?
Actually, I've suspected races in timers code.

Let's say that a particular networking timer always gets
re-added on the cpu where the timer fires.
In that case, beforehand, no inter-cpu races could possibly
be tested. But with the new timer code, such races could
now be potentially triggered.

Maybe I still miss something, but even if it were possible, lockdep
should have reported such things long ago.

Since there are still no 100% proofs nor suspects, here are some
suggestions of additional checking. This bisected commit could
probably be additionally verified by applying to 2.6.30 with a
preceding one; I attach both of them below.
Another suggestion is to try this without lockdep e.g. by setting
/sys/module/lockdep/parameters/lock_stat and prove_locking to 0.
Thanks,

commit 597d0275736dad9c3bda6f0a00a1c477dc0f37b1
Author: Arun R Bharadwaj <arun@linux.vnet.ibm.com>
Date: Thu Apr 16 12:13:26 2009 +0530
timers: Framework for identifying pinned timers
* Arun R Bharadwaj <arun@linux.vnet.ibm.com> [2009-04-16 12:11:36]:
This patch creates a new framework for identifying cpu-pinned timers
and hrtimers.
This framework is needed because pinned timers are expected to fire on
the same CPU on which they are queued. So it is essential to identify
these and not migrate them, in case there are any.
For regular timers, the currently existing add_timer_on() can be used
queue pinned timers and subsequently mod_timer_pinned() can be used
to modify the 'expires' field.
For hrtimers, new modes HRTIMER_ABS_PINNED and HRTIMER_REL_PINNED are
added to queue cpu-pinned hrtimer.
[ tglx: use .._PINNED mode argument instead of creating tons of new
functions ]

timers: Logic to move non pinned timers
* Arun R Bharadwaj <arun@linux.vnet.ibm.com> [2009-04-16 12:11:36]:
This patch migrates all non pinned timers and hrtimers to the current
idle load balancer, from all the idle CPUs. Timers firing on busy CPUs
are not migrated.
While migrating hrtimers, care should be taken to check if migrating
a hrtimer would result in a latency or not. So we compare the expiry of the
hrtimer with the next timer interrupt on the target cpu and migrate the
hrtimer only if it expires *after* the next interrupt on the target cpu.
So, added a clockevents_get_next_event() helper function to return the
next_event on the target cpu's clock_event_device.

Hello
System freezes immediatly after grub, no init processing at all, after
applying those patches on top of vanilla 2.6.30 on my box.
Also, 2nd patch, this piece:
+#ifdef CONFIG_SCHED_DEBUG
+static inline unsigned int get_sysctl_timer_migration(void)
+{
+ return sysctl_timer_migration;
+}
+#else
+static inline unsigned int get_sysctl_timer_migration(void)
+{
+ return 1;
+}
+#endif
doesnt work on top of 2.6.30. It complains, while compiling, that
sysctl_timer_migration is not defined. So i just replaced that call
with return 1, like on the not debug case. Hope this doesnt defeat
your test case, but it wouldnt compile otherwise. Probably that was
just introduced after 2.6.30?
(Have also tried latest .31-rc2, original bug still exists.)
Thank you for your time,

Yes, it would be too easy if it had worked just like this... (I only
test-compiled it, without such warnings, but without CONFIG_SCHED_DEBUG.)
I'll look at this again.

Btw., could you send your .config? Do you have lockdep enabled (if so
did you try without it)? Is it 'a real' box or something virtual?
Thanks,

Hello
.config is attached. This is a real box, a fedora 11 with rawhide
updates applied. Its a quad core system (amd phenom 9600) with 4gb
ddr2 ram. The board is an asus m3a-h/hdmi. We have a couple of these
boxes just to test run linux before dropping into production, hence
the availability for tests.
Haven't tried without lockdep, will try later and let you know if any
difference.
Thank you for your time,

Yes, my bad, sorry. I've found 2 more patches from this series; can't
guarantee that's all, but seems to work & migrate within my one and
only core without any problems ;-)

timers: Framework for identifying pinned timers
* Arun R Bharadwaj <arun@linux.vnet.ibm.com> [2009-04-16 12:11:36]:
This patch creates a new framework for identifying cpu-pinned timers
and hrtimers.
This framework is needed because pinned timers are expected to fire on
the same CPU on which they are queued. So it is essential to identify
these and not migrate them, in case there are any.
For regular timers, the currently existing add_timer_on() can be used
queue pinned timers and subsequently mod_timer_pinned() can be used
to modify the 'expires' field.
For hrtimers, new modes HRTIMER_ABS_PINNED and HRTIMER_REL_PINNED are
added to queue cpu-pinned hrtimer.
[ tglx: use .._PINNED mode argument instead of creating tons of new
functions ]

This patch creates the /proc/sys sysctl interface at
/proc/sys/kernel/timer_migration
Timer migration is enabled by default.
To disable timer migration, when CONFIG_SCHED_DEBUG = y,
echo 0 > /proc/sys/kernel/timer_migration

timers: Logic to move non pinned timers
* Arun R Bharadwaj <arun@linux.vnet.ibm.com> [2009-04-16 12:11:36]:
This patch migrates all non pinned timers and hrtimers to the current
idle load balancer, from all the idle CPUs. Timers firing on busy CPUs
are not migrated.
While migrating hrtimers, care should be taken to check if migrating
a hrtimer would result in a latency or not. So we compare the expiry of the
hrtimer with the next timer interrupt on the target cpu and migrate the
hrtimer only if it expires *after* the next interrupt on the target cpu.
So, added a clockevents_get_next_event() helper function to return the
next_event on the target cpu's clock_event_device.

Lockdep was not enabled at first. Actually I think most if not all of the
traces I posted at first were without.
Will verify.

Hello
Since i already had the kernel compiled and ready to boot when i read
this, i gave it a go anyway :-).
I can reproduce the freeze with those 4 patches applied, so i can
confirm that its, at least, related to, or exposed by, those patches.
There must be something else too, or its just too much fuzziness, but
the freeze takes a bit more time (approximately five minutes, give or
take) compared to the instant freeze before, but its there with the
patches, and without them, no freeze.
I assume there isnt a "safe" way to get them out of current .31-rc's, right?
Thank you very much for your time,

To be fair I have to admit I did run netem for 48hours for other reasons ;-)
I also ran my modified netem, but all it currently does is adjusing
delay/jitter by other means, so that should have no influence.
I am trying to produce artificial loss patterns similar to really occuring
network loss.
I just switched mail client btw ;-)
ATM I have no further ideas except maybe trying different timers or a lower
timer resolution?

I guess it should fix it entirely. Btw., here is a patch disabling the
timers' part, so to make it hrtimers only. Could you try?

I am now running 2.6.31-rc2 for a couple of hours, no freeze.
Let me know what/if i can help with tracking down the original source
of the problem.
Thank you very much for your time,

You dont see the problem anymore with the `echo 0 >
/proc/sys/kernel/timer_migration` change (or equivalently with the patch from
Jarek) or has the problem vanished completely?

OK, so we know it's only about timers. Here is another tiny patch
(the previous one should be removed), which could tell (with oops) if
there's something while migrating. Anyway, the bug should be back :-(

How do we know this? It still could be a race uncovered by timer migration,
right?

Yes. Can't reboot that machine right now, will test later.
Testing wether its triggerable inside a vm might be interesting...

Probably similarly to testing without this patch or even less. Maybe
I should've warned you but this type of bugs in -rc with possible
memory or stack overwrites might be fatal for your data (at least).

Fortunately all the data on that machine should either be replaceable or
regularly backuped.
Will test later today if that patch bugs.

If you didn't start yet, it would be nice to use this, btw:
CONFIG_HOTPLUG_CPU = N
CONFIG_DEBUG_OBJECTS = Y
CONFIG_DEBUG_OBJECTS_TIMERS = Y

So I should test with a single cpu? Or is there a config where HOTPLUG_CPU does
not imply !SMP?

No, my single cpu should be enough ;-) There is something wrong I guess.
I can see in my menuconfig:
SMP [=y]
...
HOTPLUG [=n]
...
HOTPUG_CPU [=y]
...
Depends on SMP && HOTPLUG
So, let it be HOTPLUG_CPU = Y for now...

I have to correct this information.
I had inserted `echo 0 >> /proc/sys/kernel/timer_migration` into
rc.local, and i left it there when i applied your first patch.
Im talking about this patch:
diff --git a/kernel/timer.c b/kernel/timer.c
index 0b36b9e..011429c 100644
--- a/kernel/timer.c
+++ b/kernel/timer.c

cpu = smp_processor_id();
-#if defined(CONFIG_NO_HZ) && defined(CONFIG_SMP)
+#if 0
After removing the line from rc.local, and leaving only the patch, the
freeze still happens. The patch -does not- prevent the freeze. It was
my mistake saying it does, i totally forgot i had added that line to
rc.local.
So again, the only thing that stops that freeze is `echo 0 >>
/proc/sys/kernel/timer_migration`. Apologies for pointing you in the
wrong direction.
I also tried the other patch provided:

}
but the OPS never triggers, either with your first patch or with the
echo 0 > proc[...]
I was under the impression that disabling the entry in /proc or
applying the first patch would provide the same result, but alas, it
does not.

No problem: the direction is almost right, we only need one U-turn ;-)
In case you're not bored or too bored, one little patch to check the
other side (after reverting the previous patch).

Unfortunately this just yields the same backtraces during softlockup and not
earlier.
I did not test without lockdep yet, but that should not have stopped the BUG
from appearing, right?

So, with only this last patch applied, no freeze. No need to disable
anything through /proc.
Where should i put the BUG_ON?

Hmm... Not so fast! I've looked in timers till now; "tomorrow" I'll
"change resolution". ;-)

Since it looks like hrtimers now, these changes in timers shouldn't
matter. Let's wait for new ideas.
Thanks for testing anyway,

Some background:
Up to 2.6.30 hrtimer_start() and add_timer() enqueue (hr)timers on the
CPU on which the functions are called. There is one exception when the
timer callback is currently running on another CPU then it is enqueued
on that other CPU.
The migration patches change that behaviour and enqeue the timer on
the nohz.idle_balancer CPU when parts of the system are idle.
With the migration code disabled (via sysctl or the #if 0 patch) the
timer is always enqeued on the same CPU, i.e. you get the 2.6.30
behaviour back.
As you found out it is probably related to hrtimers. Checking the
network code the only hrtimer users are in net/sched/sch_api.c and
net/sched/sch_cbq.c . There is some in net/can as well, but that's
probably irrelevant for the problem at hand.
I'm not familiar with that code, so I have no clue which problems
might pop up due to enqueueing the timer on another CPU, but there is
one pretty suspicios code sequence in cbq_ovl_delay()
expires = ktime_set(0, 0);
expires = ktime_add_ns(expires, PSCHED_US2NS(sched));
if (hrtimer_try_to_cancel(&q->delay_timer) &&
ktime_to_ns(ktime_sub(
hrtimer_get_expires(&q->delay_timer),
expires)) > 0)
hrtimer_set_expires(&q->delay_timer, expires);
hrtimer_restart(&q->delay_timer);
So we set the expiry value of the timer only when the timer was active
(hrtimer_try_to_cancel() returned != 0) and the new expiry time is
before the expiry time which was in the active timer. If the timer was
inactive we start the timer with the last expiry time which is
probably already in the past.
I'm quite sure that this is not causing the migration problem, because
we do not enqueue it on a different CPU when the timer is already
expired.
For completeness: hrtimer_try_to_cancel() can return -1 when the timer
callback is running. So in that case we also fiddle with the expiry
value and restart the timer while the callback code itself might do
the same. There is no serializiation of that code and the callback it
seems. The watchdog timer callback in sch_api.c is not serialized
either.
There is another oddity in cbq_undelay() which is the hrtimer callback
function:
if (delay) {
ktime_t time;
time = ktime_set(0, 0);
time = ktime_add_ns(time, PSCHED_TICKS2NS(now + delay));
hrtimer_start(&q->delay_timer, time, HRTIMER_MODE_ABS);
The canocial way to restart a hrtimer from the callback function is to
set the expiry value and return HRTIMER_RESTART.
}
sch->flags &= ~TCQ_F_THROTTLED;
__netif_schedule(qdisc_root(sch));
return HRTIMER_NORESTART;
Again, this should not cause the timer to be enqueued on another CPU
as we do not enqueue on a different CPU when the callback is running,
but see above ...
I have the feeling that the code relies on some implicit cpu
boundness, which is not longer guaranteed with the timer migration
changes, but that's a question for the network experts.
Thanks,

OK, that's for later because we didn't use cbq here.

As a matter of fact, I've just looked at this __netif_schedule(),
which really is cpu bound, so you might be 100% right.

So the watchdog is the one which causes the trouble. The patch below
should fix this.

I hope so. On the other hand it seems it should work with this
migration yet, so it probably needs additional debugging.

Right. I just provided the patch to narrow down the problem, but
please test the fix of the hrtimer migration code which I sent out a
bit earlier: http://lkml.org/lkml/2009/7/9/150
It fixes a possible endless loop in the timer code which is related to
the migration changes. Looking at the backtraces of the spinlock
lockup I think that is what you hit.
spin_lock(root_lock);
qdisc_run(q);
__qdisc_run(q);
dequeue_skb(q);
q->dequeue(q);
qdisc_watchdog_schedule();
hrtimer_start();
switch_hrtimer_base(); <- loops forever
Now the other CPU is stuck in dev_xmit() spin_lock(root_lock)

Actually, Andres and Joao hit this, and I hope they'll try these two
patches.

Please test them separate from each other. The one I sent in this
thread was just for narrowing down the issue, but I'm now quite sure
that they really hit the issue which is addressed by the hrtimer
patch.

No crash yet. 15min running (seconds to a minute before).
Will let it run for some hours to be sure.
Nice!
