2.6.32-rc4: Reported regressions from 2.6.31

2.6.32-rc4: Reported regressions from 2.6.31

[Rafael J. Wysocki]

[Note:
  We started to get more regression reports for 2.6.32-rc (100%+ jump in the
  last 10 days.  Nevertheless, we're still receiving new reports of regressions
  from 2.6.30.]

This message contains a list of some regressions from 2.6.31, for which there
are no fixes in the mainline I know of.  If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.31, please let me know
either and I'll add them to the list.  Also, please let me know if any of the
entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

Johannes posted a patch here:

	http://marc.info/?l=linux-wireless&m=125525657120789&w=2

It is on my merge train, but it hasn't gone to Linus (or Dave) just
yet -- probably today.

Hth!

rfkill-ing the device off and then on fixes the problem.

I don't know what to do about this one.

The user indicates that they have the vserver patches applied,
so maybe there is some interaction with that stuff.

Actually i don't think that it's Vserver related.

I'm not a kernel hacker but the vserver patch doesn't seems to have much 
relation with networking (for who don't know vserver, it's a sort of 
advanced chroot).

I'm using OCFS2 and drbd. Both of those 2 things make heavy use of 
networking to share data between two hosts.

The backtrace seems to begin in the "world" of OFCS2.
I'm CC'ing ocfs mailing list where someome may have some clues.

Thanks,
Max

Actually i found another oops which is very similar to the previous one.
Here, vserver is not involved, and the problem starts at drbd which 
lives in kernel space (the other oops started at ocfs2).

Both ocfs2 and drbd make heavy use of network I/O so i guess the problem 
is something in the network layer.

Anything i can do to help to debugging and solving this issue ?

Thanks
Max

And here it is another one, this time triggered by postfix, where mor 
drbd nor vserver are involved.
This is not the same server where the other oopses were grabbed.

Problem is kfree_skb() is called from irq context, wich is not allowed.

static void skb_release_head_state(struct sk_buff *skb)
{
...
if (skb->destructor) {
	WARN_ON(in_irq());
	skb->destructor();
}
...
}

virtio_net start_xmit() function calls free_old_xmit_skbs() and 
free_old_xmit_skbs() ultimately calls kfree_skb()

Quick fix would be to use dev_kfree_skb_any() instead,
because netpoll can definitly calls start_xmit()
with irq disabled.

Could you please following patch ?

Indeed, because of netpoll(), that is something drivers
must be able to cope with.

Indeed, let us know how Eric's patch works.

Thanks Eric!

Eric,
thanks for the patch.
The problem didn't arise again and i haven't seen any warning like that 
on both servers where that problem was happening more frequently.

I would say that it's fixed and if it's not, i'll let you know as soon 
as it happens again.

Thanks again,
Max

[PATCH] virtio_net: use dev_kfree_skb_any() in free_old_xmit_skbs()

Thanks Massimo, I think patch is reasonably safe and should be taken as is :


[PATCH] virtio_net: use dev_kfree_skb_any() in free_old_xmit_skbs()

Because netpoll can call netdevice start_xmit() method with
irqs disabled, drivers should not call kfree_skb() from
their start_xmit(), but use dev_kfree_skb_any() instead.

Patch at http://bugzilla.kernel.org/show_bug.cgi?id=14379#c1 fixes the
warning.

Actually, the _BIF warning was fixed at commit
e899b6485c332aa2d7510739507ab5e5d7b28e59.
See http://bugzilla.kernel.org/show_bug.cgi?id=11822#c14 

I made a mistake at the cleanup of predefined method table so the
warning shows up again.

Cool, I can give that a try.
then I guess just leave this open(bugreport) until this patch
http://bugzilla.kernel.org/show_bug.cgi?id=14379#c1
gets pushed into the main tree then close the bugreport.
