Yes, it's a 2.6.37.2 kernel.
OK, here's a debugging patch.
Please run with slab debugging as previously until you see
'eventfd bug detected!' in dmesg or until there is a crash.
It might be also useful to enable timestampts on printk with
  Symbol: PRINTK_TIME [=y]
   â Type  : boolean
   â Prompt: Show timing information on printks

once you see the error, please upload the
full dmesg output somewhere to we can track what
goes on.

Hopefully there won't be an oops this time which
should make it easier for you to test (no need to
reboot).

Hi,

I boot the host with the patched kernel yesterday.
No crach until now, but two "Eventfd bug detected!" in the log at
"Mar  9 02:04:31" and "Mar  9 02:15:17"
You can find part of the log at the following adress:
http://filex.univ-nantes.fr/get?k=jL4Fe7yfSMN57toAH7V

It a split file of the kern.log (1,4G), so if you need another part
of the log, let me know.

Thanks for all.

Regards.
Downloading, it's big :)
What about some 1000 lines before and after Eventfd bug detected! line?

Yes, sorry about that.
I could have split my log into a smaller file.

I was a little afraid of not transmit enough informations, and i was
a bit wide.
I hope you can find usefull trace anyway.

Regards.
OK, use after free.

and 1802201963 is also 6b6b6b6b.


I suspect that somehow, we get an event from eventfd even
though we did eventfd_ctx_remove_wait_queue.
Could you please try the following patch on top?
When you see Eventfd bug or Wakeup bug, paste some
last lines.
For the full log file - better compress with xz.

You can find all the trace at the following adress:
http://filex.univ-nantes.fr/get?k=R94kna5sckVmdvCoKsn

It's a tar.gz of seven file, from 100k to 200k each ;)

Again, thanks a lot for the time you spent on this.

Regards.
Are you running a preemptible kernel?
Does the following help at all?

diff --git a/virt/kvm/eventfd.c b/virt/kvm/eventfd.c

Hi,

thanks for the response.

root@ayrshire:~# zcat /proc/config.gz | grep -i preempt
# CONFIG_PREEMPT_RCU is not set
CONFIG_PREEMPT_NOTIFIERS=y
CONFIG_PREEMPT_NONE=y
# CONFIG_PREEMPT_VOLUNTARY is not set
# CONFIG_PREEMPT is not set

It does not seem to be a preemptible kernel.

I will test tour patch, and report the result.

Regards.
