I felt, something is wrong in dpram_write function, But couldnt exactly
know what happend.
Even i tried disassembling the function, i traced to some normal jump
instruction.

I know this error comes when, some function sleeps in atomic context.

Can anyone pls help me in fixing this..

THanks

Is it your code that's failing here?
Otherwise a good bug report on linux-kernel at vger.kernel.org is usually
appreciated.

You should consider imforming the mwlan_aarp module's vendor/maintainer;
Few kernel people like to debug someone else's proprietary code ;-).

BUG: scheduling while atomic

[James Courtier-Dutton]

I am seeing a server halt and require a manual restart that I think
might be related to btrfs.
I attach the kernel log from it, in the hope that someone will
understand it better than me.
Any clues?

Kind Regards

James

When checking the dmesg, we should check for the first backtrace other
than later backtraces, which are normally caused by the first problem.

In your case, it's general protection happens at timerqueue_add(), which
is unrelated to btrfs at all.

Sorry, my fault.

Then it makes sense why a lot of messages looks interrupted.

Then it makes sense, as it's a WARN_ON() line, showing one extent map is
still used.

If it get freed, it will definitely cause some rbtree corruption.

It's should be the only free_extent_map() call in __do_readpage() function.
However a first glance into this function shows nothing wrong, nor new
modification in this function.
(Maybe it's the get_extent() hook?)

Is there any reproducer? Or special workload?

And, have you tried "btrfs check --readonly <device>"? If there is any
error it would help a lot to locate the problem.

Thanks,
Qu

The workload is fairly simple.
1) The server is receiving 1Gbyte files from across the network, in 10
minute intervals, and storing them on the HDD.
2) A process reads the files, scanning them for certain patterns.
3) A cron job deletes the old files.

This looks pretty normal.
Shouldn't cause any problem.

This problem can be solved by "btrfs check --clear-space-cache=v1".
Normally it shouldn't cause much problem.

Not really.

If it's still reproducible, maybe it's worth trying the latest upstream
kernel.

BUG: scheduling while atomic

[Mushtaq Khan]

Hi,
 I see error message "BUG: scheduling while atomic"intermittently. As
per other post on similar  issue, this happens when schedule is called
from either interrupt
 context or some other atomic operation (Might be after acquiring
spinlock). But from the call trace am not getting any clue, please
help me guide  on this issue.
Using Linux 3.4rt.

That P in your drivers suggests that you have non GPL code in your
kernel.
You could increase the debugging level and check who disabled preemption
and then working around it.

BUG: scheduling while atomic

[Arun KS]

Hello Guys,

System is working normal after this BUG.
PC is at 0x400b4614, probably a mmaped address.

Just wondering how can this BUG happen when a process is running in user
space.

Can it be something like this
1) enter to kernel from userspace through some system call.
2) kernel disables the interrupt and return to user space.
3) and now it can happen in user space?

Any thoughts?

Don't do that.

Because something in userspace made a blocking call which would cause
a context switch to occur and your driver erroneously left interrupts
disabled.

I don't do that. This scenario mentioned is a just a wild guess.

In that case, my system should have been unstable afterwards if interrupts
are left disabled. But that is not happening.

If we return to user space with interrupts disabled, can we switch back
again to kernel using a system cal(because interrupts are already disabled)?

As long as you don't do anything which would need to block.

A buggy driver could also interrupt user-code (hardware interrupt) and
disable interrupts and not re-enable them.

Depends on how many CPUs you have - AFAICS the "interrupts disabled"
discussion above applies to a single CPU.. so if you have other CPUs on your
system, you could probably use the system for a little more time.

 

There is a simple way to check if interrupts are indeed disabled as
hypothesised: turn on the hard-lockup detector (See
Documentation/lockup-watchdogs.txt for details on what it is and what
config options you have to enable). You can even turn on the soft-lockup
detector and see what you get. Setting the option to panic on hard-lockup/
soft-lockup/hung tasks would be even better, to debug the issue.

Thanks for the pointers. I ll try this out.

But if you look at the flags here,  it is showing that IRQs are on.

So, an atomic context, as far as the kernel is concerned, also
includes disabling preemption, not just disabling interrupts.

BUG: scheduling while atomic

[Florian Tobias Schandinat]

Hi all,

since I upgraded to 3.3-rc3 I received this bug. Probably a regression although
I also recently updated git, so I can't say for sure. It looks like it happens
quite often here when doing git push in kernel trees.

BUG: scheduling while atomic

[Amon Ott]

[-- Attachment #1: Type: text/plain, Size: 598 bytes --]

Sorry folks for making so much trouble,

but there is still another locking issue with the kernel client. iput gets 
called with locks held, but iput can sleep and did in this occasion. It did 
not hang the system this time, but it can be quite nasty.

Log attached as usual.

Re: BUG: scheduling while atomic

Hello list, Alan,

I got the same error  with pptpgw as Sergey after switching form  
2.6.30 to recent git (rc1).

     ppp: Fix throttling bugs

So I do not understand why this is still happening here. My call trace  
looks different than the one from Sergey so I do not know if I am  
hitting the same problem.
2.6.30 is rock solid.

Yes - I've no idea what is going on with the pptpgw traces at the moment.

The path is

	pptpgw reads from the tty side (it uses a pty/tty pair and runs
	ppp over it)

	This calls the ldisc n_tty_read
		We copy some data and this makes room in the buffers
	ww call check_unthrottle (with no spinlocks held)
		This decides that thre is now room to ask the other end
		to send more
	which calls tty_unthrottle (which takes only a mutex)
	which calls pty_unthrottle
		which wakes the other side of the pty/tty pair for writing
	this calls the ppp ldisc wakeup handler for the other side
	which blows up somewhere around the tasklet code for no reason I
		can make sense of yet


and all of this should be (and seems to be) getting called with sleeping
allowed and no spinlocks taken in error.

You could stuff calls to might_sleep() in pty_unthrottle and
check_unthrottle and see which ones are triggered if any.

Hello Alan,

I am not sure if the might_sleep entries are at the correct position  
but it apparently did not make a difference.

I think the first backtrace is bogus, this is where the real
problem is.  So what see here is that on xmit from the network,
PPP will call pty_write from BH context which eventually leads
to tty_throttle and the sleep.

Here's the stupidest possible fix for this, changing the mutex
to a spin lock.  We should also revert the other commit that
tried to fix this, a6540f731d506d9e82444cf0020e716613d4c46c as
those unthrottles are really needed (the pty driver is always
in the throttled state, so that's why there are no explicit calls
to throttle).

tty: Use spin lock instead of mutex for throttling

Commit 38db89799bdf11625a831c5af33938dcb11908b6 (tty: throttling
race fix) added a mutex to the throttle/unthrottle paths.  This
broke PPP because the PPP ldisc calls both throttle and unthrottle
from softirq contexts.

Since any tty device that's been used together with PPP has clearly
coped with throttling and unthrottling in softirq contexts, we can
turn the mutex into a spin lock.

The added protection of termios consistency does not appear to be
needed as it stands.  When it is needed, we'll have to redo the
locking, or change the throttle/unthrottle implementation that
needs it.

Just to confirm.
I reverted the commit and applied the patch on-top of 2.6.31-rc2.
Up to now I was not able to reproduce the crashes I had before on my  
setup here.

Crashes my box immediately. The unthrottle methods call sleeping driver
functions with real hardware so

NAK

If it was that simple I'd have done this ages ago. It has to be fixed
properly, and that is hard.

Re: BUG: scheduling while atomic

[Alan Cox]

This is the more drastic way of doing it. I had hoped to put this off but
in fact it cleans stuff up enormously. This has had only basic testing
but the underlying idea is to simply remove all the pty special casing
that causes messes in the first place.

pty: Rework the pty layer to use the normal buffering logic

From: Alan Cox <alan@linux.intel.com>

This fixes the ppp problems and various other issues with call locking
caused by one side of a pty called in one locking context trying to match
another with differing rules on the other side. We also get a big slack
space to work with that means we can bury the flow control deadlock case
for any conceivable real world situation.

Hi Alan,

Must commit a6540f731d506d9e82444cf0020e716613d4c46c still be reverted  
with your patch or can it stay in?

No crashes with the reverted commit and Alan's patch on my hardware  
here.
A Load Test that would trigger it after some seconds is now running  
for several minutes without any problems.

That would I fit the symptoms and also explain why some broken versions
of the USB code on embedded devices also exploded with PPP over USB links.

Not however at all easy to fix as it only ever worked in the past on the
"close both eyes, pray and jump" principle of locking.

Added to the todo list for later this week. The pty layer has all sorts
of magic hackery to allow it to call back and forth without going via
internal tty buffering like normal hardware. That may have to die as it
causes other horrible problems too.

Looks like we caught another naughty. It's not safe to call the
throttle/unthrottle methods from an IRQ path, never really has been as
they can be things like USB drivers that need to send USB messages and
sleep when that happens.

Just delete the tty_unthrottle() from drivers/net/ppp/ppp_async.c - it
never throttles the port so it never needs to unthrottle it (which is why
it happened never to cause crashes before)

I'm not sure about that.  The PTY driver is always in the throttled
state, so tty_unthrottle isn't a noop.

Bug:scheduling while atomic

[Vijay Nikam]

Hello All,

I have mpc8313erb with linux kernel 2.6.20.

When I ported the kernel with CONFIG_PREEMPT=y (Enabled) I am getting
the 'scheduling while atomic'. Please check the following call trace,
thanks.

Could anyone please let me to the way to fix it ? ? ?

Kindly please acknowledge ... thank you ...

Kind Regards,
Vijay Nikam

Have you tried a newer kernel (like 2.6.29) and see if the issue still  
exists.

BUG: scheduling while atomic

It happens with wireless-testing, v2.6.25-rc5-2623-g7556b76. I've no
additional patch from me on top of this.

does

that is running under a spinlock, namely the device's tx lock.

Thanks for explaining. I think I introduced this bug. I
just wonder why I didn't see it before, e.g. I didn't see
it this morning or when I was testing my patch "convert
CMD_MAC_CONTROL to a direct command"


This patch snippet from me produced the bug:


 int lbs_set_mac_packet_filter(struct lbs_private *priv)
 {
        int ret = 0;
+       struct cmd_ds_mac_control cmd;

        lbs_deb_enter(LBS_DEB_CMD);

-       /* Send MAC control command to station */
-       ret = lbs_prepare_and_send_command(priv,
-                                   CMD_MAC_CONTROL, 0, 0, 0, NULL);
+       cmd.hdr.size = cpu_to_le16(sizeof(cmd));
+       cmd.action = cpu_to_le16(priv->currentpacketfilter);
+       cmd.reserved = 0;
+
+       ret = lbs_cmd_with_response(priv, CMD_MAC_CONTROL, &cmd);



The original code did not contain CMD_OPTION_WAITFORRSP, so my
translation to lbs_cmd_with_response() was wrong. I'll cook up
a patch soon.

I'm using 2.6.24-rc8 on a PPC 440 and getting this error. I've also seen
another form of it when doing Telnet.

 

In this case, I'm doing a copy of a file on an NFS mount.

 

Any help would be appreciated.

 

Thanks,

BUG: scheduling while atomic

[Christian]

Hello lkml,

while playing enemy-territory it sometimes hangs the X server and I need to 
hard-reset the machine. I managed to get a trace of the problem this time. 
The kernel is tainted with the binary NVIDIA driver. I hope someone from 
NVIDIA follows the list. I know that there will be no support for a tainted 
kernel on lkml. This mail is "for information" only!

problems... everytime i try to spawn the snmpd process I got a kernel
backtrace as follows, and the process never cames up:

great.. installed 2.6.17-rc5, rebooted, started snpd and it true, no
backtrace... but also... no process is spawned... no snmpd is created,
no error, nothing on logs, nothing :( :( i'm cursed....
