Hi

Recently I'm getting complete system freeze during reboot - usually
just after iptables frees modules the oops strikes in - oops is taken
via serial console on the second machine - as this machine is
completely dead in this moment.

I'm using a lot of memory debug options - so this might be the result?
- looks like some memory gets mangled??.    For some time I've
suspected kmemleak - thus I've been not reporting it when it happened
for the first time (few weeks already) - but this kernel is compiled
without kmemleak and still crashes.

Also the crash will not happen with booting to single mode - the full
startup (without Xorg) must happen to get this crash on reboot.

My machine is  T61, 4GB, C2D,  x86_64
Kernel vanilla git commit:  85dfd81dc57e8183a277ddd7a56aa65c96f3f487
with two very small unrelated patches on top of this.
.config attached.

Looks like slab data corruption on early boot that cannot be reported
since the system has not fully bootstrapped yet. Instead of a report you
get a general protection fault. The primary issue is slab data corruption
though.

Well - I've tried to switch from  'slub' allocator to  old 'slab'
allocator and the problem is gone - shutdown goes without any problem.

So it's probably related to 'slub' allocator only?

Is there anything else I could try to better detect this problem?

(well the bisect should be last resort - as it might be pretty lengthy
- I'm not really sure which kernel would be actually good for the
start)

The slab allocator does not have all the diagnostics of slub. The issue
may simply not be detected in slab. If you switch off diagnostics in slub
then everything will seem to work fine as well. But we need to figure out
what is going wrong here.

>anything else I could try to better detect this problem?

Does it work with 2.6.30?

If you can do debugging during bootstrap (kvm?) then set a breakpoint at
slab_bug. The registers have enough information to get the error message
at that point.

The last released stable kernel is a good point to start.

Hmm - but there are few things -

My machine runs  Fedora Rawhide. If I run the same kernel within KVM
running Debian unstable I could easily reboot this guest machine
without any problems.

Also if I boot Rawhide only to single mode - I could also reboot
machine without this oops.
The problem seems to be - when I do full machine startup to the
multiuser runlevel 3

Another issue which might make hunting for the problem harder is -
that kvm doesn't have the same ACPI like I have on my Lenovo laptop.
So the KVM doesn't  help here probably?
(I assume most probably some hw initialization overwrites something somewhere ?)

I've no idea - I'll need to rebuild couple kernels - I've enabled
these debugs options only recently.

How setting the breakpoint during boot process helps here ??
I'm getting this oops during shutdown - just before machine goes off.

Ok - I guess it will take couple hours....

Try booting all the way and recording you output from lsmod.  Reboot
single user mode and modprobe each of the modules in that original lists.
Test shutdown from single user mode.  This might identify if it is one
of your loaded modules.  If so, effectively bisect the modprobes until
you find the offending module(s).

Ok - it appeared to be more complex - when I've been trying to get
this oops on my laptop while not being connected via wired net - but
to not bother here with details - the result is

That if I remove nf_conntrack_ipv4.ko  - so it can not be loaded - the
problem is gone.
So it looks like the memory problem is related to netfiltering - there
are multiple modules loaded as dependecy becuase of this - so it's
hard to say exactly which module of them makes the trouble.

I've checked for some recent commits in this area - and they seem to
be actually important
(i.e 941297f443f871b8c3372feccf27a8733f6ce9e9  16.Jul)

I could probably try to revert some of them - but if someone has some
ideas what could make these problems ?

I've added authors of some recent conntrack commits to Cc: - maybe
they might know?

I've tested v2.6.30 - and it's crashing in the same way - so any other
starting point where slub has the same detection mechanism and
conntrack module should be working reliable ?

Next point is 2.6.29.

Ok  - played lengthy game between 2.6.29 which appeared to be ok and 2.6.30

And the winner is: ea781f197d6a835cbb93a0bf88ee1696296ed8aa
netfilter: nf_conntrack: use SLAB_DESTROY_BY_RCU and get rid of call_rcu()

The error is actually being hit by  libvirtd networking rules added
during boot for my kvm usage.
(Which I noticed after some time...  leading my game into wrong
direction ;))....

Here are the some last bisect entries:

Unfortunately the commit cannot be reverted with current tree - thus I
cannot easily check if it's the only problem.
(warning: too many files (created: 3096 deleted: 1096), skipping
inexact rename detection
Automatic revert failed.  After resolving the conflicts,)

Hmm after checking today with serial cable attached - it looks like
I've tracked the problem but to the wrong commit - my original 'slub'
error was now actually something else - so there are most probably two
kinds of problem - as with this kernel the nf_conntrack_ipv4 fails to
register tcp so it's not loaded at all.
This might get fixed later, but different error was there.

I'll need to play the game again and check when I'll start to get the
same slub oops/

Here is the second oops I've got with 2.6.29-rc5 kernel:

Hello Zdenek

I am currently traveling and wont be able to help you before next week.

I added netdev, Patrick, and netfilter-devel in CC so that more eyes can take a look.

Thank you

Thanks for the report, I'll have a look at this. Zdenek, please
send me the nf_conntrack.ko file used in the above oops. Thanks.

Ok

I've found the solution for my problem.

http://thread.gmane.org/gmane.comp.security.firewalls.netfilter.devel/30483

I've made this small fix from this thread:

                ret = -ENOMEM;


As the thread nf_conntrack: Use rcu_barrier() and fix kmem_cache_create flags
seems to be samewhat 'unfinished'  and already a bit old and I've no
idea whether it actually fixes problem completely or just hides it in
my case - I'm leaving it to some RCU gurus to fix this issue.

All I could say is - this this extra rcu_barrier() and removal of
SLAB_DESTROY removes my GPF on reboot.

Ouch..

Dont think such a patch makes your kernel better, it'll crash too.

You cannot remove SLAB_DESTROY_BY_RCU like this, it's there for very good reasons.

Well I'm not noticing any ill behavior - also note - rcu_barrier() is
there before the cache is destroyed.
But as I said - it's just my shot into the dark - which seems to work for me...

Reading again your traces, I do believe there are two bugs in slub

Maybe not explaining your problem, but worth to fix !

Thank you

[PATCH] slub: fix slab_pad_check() and SLAB_DESTROY_BY_RCU

When SLAB_POISON is used and slab_pad_check() finds an overwrite of the
slab padding, we call restore_bytes() on the whole slab, not only
on the padding.

kmem_cache_destroy() should call rcu_barrier() *after* kmem_cache_close()
and *before* sysfs_slab_remove() or risk rcu_free_slab()
being called after kmem_cache is deleted (kfreed).

rmmod nf_conntrack can crash the machine because it has to
kmem_cache_destroy() a SLAB_DESTROY_BY_RCU enabled cache.

The rcu_barrier() call was added by this commit:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=7ed9f7e5db58c6e8c2b4b738a75d5dcd8e17aad5

I guess we should CC Paul as well.

Sure !

rcu_barrier() is definitly better than synchronize_rcu() in 
kmem_cache_destroy()

But its location was not really right (for SLUB at least)

SLAB_DESTROY_BY_RCU means subsystem will call kfree(elems) without waiting RCU
grace period.

By the time subsystem calls kmem_cache_destroy(), all previously allocated
elems must have already be kfreed() by this subsystem.

We must however wait that all slabs, queued for freeing by rcu_free_slab(),
are indeed freed, since this freeing needs access to kmem_cache pointer.

As kmem_cache_close() might clean/purge the cache and call rcu_free_slab(),
we must call rcu_barrier() *after* kmem_cache_close(), and before kfree(kmem_cache *s)

Alternatively we could delay this final kfree(s) (with call_rcu()) but would
have to copy s->name in kmem_cache_create() instead of keeping a pointer to
 a string that might be in a module, and freed at rmmod time.

Given that there is few uses in current tree that call kmem_cache_destroy()
on a SLAB_DESTROY_BY_RCU cache, there is no need to try to optimize this
rcu_barrier() call, unless we want superfast reboot/halt sequences...

Oh, sure, the fix looks sane to me. It's just that I am a complete
coward when it comes to merging RCU related patches so I always try to
fish an Acked-by from Paul or Christoph ;).

I agree that moving the rcu_barrier() as you have done is the right
thing to do -- no point in doing the rcu_barrier() unless you actually
are destroying the kmem_cache!

Good news !

Hmm... but you had a problem with a 2.6.29.something kernel if I remember well ?

At that time, conntrack did not use SLAB_DESTROY_BY_RCU yet.

Right. I didn't remember that I merged that over your NAK but I don't
share your view that kmem_cache_destroy() callers should do
rcu_barrier() or whatever is necessary if we can do it from
kmem_cache_destroy(). So I am happy to take both changes but I would
appreciate them being split into two separate patches.

Do you mean :

if (kmem_cache_shrink(s) == 0) {
	rcu_barrier();
	kmem_cache_destroy_no_rcu_barrier(s);
} else {
	kmem_cache_destroy_with_rcu_barrier_because_SLAB_DESTROY_BY_RCU_cache(s);
}

What would be the point ?

Sure, here is the poison thing

[PATCH] slub: fix slab_pad_check()

When SLAB_POISON is used and slab_pad_check() finds an overwrite of the
slab padding, we call restore_bytes() on the whole slab, not only
on the padding.

Here is the second patch (RCU thing). Stable candidate

[PATCH] slub: Fix kmem_cache_destroy() with SLAB_DESTROY_BY_RCU

kmem_cache_destroy() should call rcu_barrier() *after* kmem_cache_close()
and *before* sysfs_slab_remove() or risk rcu_free_slab()
being called after kmem_cache is deleted (kfreed).

rmmod nf_conntrack can crash the machine because it has to
kmem_cache_destroy() a SLAB_DESTROY_BY_RCU enabled cache.

Yes - but it was also giving different error message - which even not
loaded ftp conntrack module. Basically it has been fine until
conntrack started to use rcu. From that moment various errors started
to appear with slub and some kernel debugging options - slab was fine.
With your recent patch it's the first time I do not see oops with nf
after 2.6.29 kernel.

Which is precisely the point of the rcu_barrier(), right?

No, I am trying to code what you suggest, and I could not find a clean way with
current API (SLAB/SLUB/SLOB)

Point is we cannot deal with RCU quietness before disposing the slab cache,
(if SLAB_DESTROY_BY_RCU was set on the cache) since this disposing *will* 
make call_rcu() calls when a full slab is freed/purged.
And when RCU grace period is elapsed, the callback *will* need access to 
the cache we want to dismantle. Better to not have kfreed()/poisoned it...

I believe you mix two RCU uses here.

1) The one we all know, is use normal caches (!SLAB_DESTROY_BY_RCU) 
(or kmalloc()), and use call_rcu(... kfree_something)

   In this case, you are 100% right that the subsystem itself has
   to call rcu_barrier() (or respect whatever self-synchro) itself,
   before calling kmem_cache_destroy()

2) The SLAB_DESTROY_BY_RCU one.

   Part of cache dismantle needs to call rcu_barrier() itself.
   Caller doesnt have to use rcu_barrier(). It would be a waste of time,
   as kmem_cache_destroy() will refill rcu wait queues with its own stuff.

Suppose we have the following sequence of events:

1.	CPU 0 is running a task that is using the slab cache.

	This CPU does kmem_cache_free(), which happens to free up
	some memory to the system.  Because SLAB_DESTROY_BY_RCU is
	set, an RCU callback is posted to do the actual freeing.

	Please note that this RCU callback is internal to the slab,
	so that the slab user cannot be aware of it.  In fact, the
	slab user isn't doing any call_rcu()s whatever.

2.	CPU 0 discovers that the slab cache can now be destroyed.

	It determines that there are no users, and has guaranteed
	that there will be no future users.  So it knows that it
	can safely do kmem_cache_destroy().

3.	In absence of rcu_barrier(), kmem_cache_destroy() would
	immediately tear down the slab data structures.

4.	At the end of the next grace period, the RCU callback posted
	(again, internally by the slab cache) is invoked.  It has a
	coronary due to the slab data structures having already been
	freed, and (worse yet) possibly reallocated for other uses.

Hence the need for the rcu_barrier() when tearing down SLAB_DESTROY_BY_RCU
slab caches.

Which is irrelevant.  The outstanding RCU callback was posted by the

Unless I am missing something, this patch re-introduces the bug that
the rcu_barrier() was added to prevent.  So, in absence of a better
explanation of what I am missing:

NACK.

I stilll think that the action to quiesce rcu is something that the caller
of kmem_cache_destroy must take care of.

Could you split this into two patches: One that addresses the poison and
another that deals with rcu?

I am fine with acking the poison piece.

I did not ack the patch that added rcu to kmem_cache_destroy() and I
likely wont ack that piece either.

It seems very smart, but needs review of all callers to make sure no slabs
are waiting for final freeing in call_rcu queue on some cpu.

I suspect most of them will then have to use rcu_barrier() before calling
kmem_cache_destroy(), so why not factorizing code in one place ?

And if I understand correctly, this is more evidence that
kmem_cache_destroy() needs to do an rcu_barrier() in the
SLAB_DESTROY_BY_RCU case.

And if I understand correctly, this is more evidence that
kmem_cache_destroy() needs to do an rcu_barrier() in the
SLAB_DESTROY_BY_RCU case.

The above is port of slub?

I mean that (in this case) the net subsystem would have to deal with RCU quietness
before disposing of the slab cache. There may be multiple ways of dealing
with RCU. The RCU barrier may be unnecessary for future uses. Typically
one would expect that all deferred handling of structures must be complete
for correctness before disposing of the whole cache.

\x10[snip]

Can someone please explain what's the upside in Christoph's approach?
Performance? Correctness? Something else entirely? We're looking at a
tested bug fix here and I don't understand why I shouldn't just go
ahead and merge it. Hmm?

There is no need to do call_rcu calls for frees at that point since
objects are no longer in use. We could simply disable SLAB_DESTROY_BY_RCU
for the final clearing of caches.

But going through the RCU period is pointless since no user of the cache
remains.

The dismantling does not need RCU since there are no operations on the
objects in progress. So simply switch DESTROY_BY_RCU off for close.

OK, this is in for-next now and queued for 2.6.31. If you guys want to
fix this in a different way, lets do that in 2.6.32.

Well, I can crash my 2.6.30.5 machine just doing rmmod nf_conntrack

(You'll need CONFIG_SLUB_DEBUG_ON or equivalent)

If by "you must ensure" you mean "kmem_cache_destroy must ensure", then
we are in complete agreement.  Otherwise, not a chance.

That is true.  However, there well might be RCU callbacks generated by
kmem_cache_free() that have not yet been invoked.  Since kmem_cache_free()
generated them, it is ridiculous to insist that the user account for them.
That responsibility must instead fall on kmem_cache_destroy().

If by "must ensure that no objects are in use", you mean "must have
no further references to them", then we are in agreement.  And in my
scenario above, it is not the -user- who later references the memory,
but rather the slab code itself.

Put the rcu_barrier() in kmem_cache_free().  Please.

Problem is not _objects_ Christoph, but _slabs_, and your patch is not working.

Its true that when User calls kmem_cache_destroy(), all _objects_ were previously freed.
This is mandatory, with or withou SLAB_DESTROY_BY_RCU thing

Problem is that slub has some internal state, including some to-be-freed _slabs_,
that User have no control at all on it.

User cannot "know" slabs are freed, inuse, or whatever state in cache or call_rcu queues.

Face it, SLAB_DESTROY_BY_RCU is internal affair (to slub/slab/... allocators)

We absolutely need a rcu_barrier() somewhere, believe it or not. You can argue that it should
be done *before*, but it gives no speedup, only potential bugs.

Only case User should do its rcu_barrier() itself is if it knows some call_rcu() are pending
and are delaying _objects_ freeing (typical !SLAB_DESTROY_RCU usage in RCU algos).

I dont even understand why you care so much about kmem_cache_destroy(SLAB_DESTROY_BY_RCU),
given that almost nobody use it. We took almost one month to find out what the bug was in first
place...

So maybe the safest thing would be to include the rcu_barrier() to insure all objects where freed

And another one for SLAB_DESTROY_BY_RCU to make sure slabs where freed

void kmem_cache_destroy(struct kmem_cache *s)
{
	/*
	 * Make sure no objects are waiting in call_rcu queues to be freed
	 */
	rcu_barrier();

	down_write(&slub_lock);
	s->refcount--;
	if (!s->refcount) {
                list_del(&s->list);
                up_write(&slub_lock);
                if (kmem_cache_close(s)) {
                        printk(KERN_ERR "SLUB %s: %s called for cache that "
                                "still has objects.\n", s->name, __func__);
                        dump_stack();
                }
		/*
		 * Make sure no slabs are waiting in call_rcu queues to be freed
		 */
                if (s->flags & SLAB_DESTROY_BY_RCU)
                        rcu_barrier();
                sysfs_slab_remove(s);
        } else
                up_write(&slub_lock);
}

Of course. This has been discussed before.

You need to ensure that no objects are in use before destroying a slab. In
case of DESTROY_BY_RCU you must ensure that there are no potential
readers. So use a suitable rcu barrier or something else like a
synchronize_rcu...

There will be no rcu callbacks generated at kmem_cache_destroy with the
patch I posted.

The "fix" was ill advised. Slab users must ensure that no objects are in
use before destroying a slab. Only the slab users know how the objects
are being used. The slab allocator itself cannot know how to ensure that
there are no pending references. Putting a rcu_barrier in there creates an
inconsistency in the operation of kmem_cache_destroy() and an expectation
of functionality that the function cannot provide.

Yes. Again this is the first time we encounter a situation where a
DESTROY_BY_RCU slab has to be destroyed. So the review is quite short.

There are different forms of RCU which require different forms of
barriers. Its best to leave that up to the user. Again the user must make
sure that no objects are in use before a slab is destroyed. For
SLAB_DESTROY_BY_RCU this means that there are no potential outstanding
reads on the structure. You may need an rcu_barrier() to accomplish that.

Slight variations in the use of RCU could require different method. Better
reduce the entanglement of slabs to RCU to a mininum possible.

If it were the user of the slab who was invoking some variant of
call_rcu(), then I would agree with you.

However, call_rcu() is instead being invoked by the slab itself in the
case of SLAB_DESTROY_BY_RCU, so that there is no variation in usage.
Requiring that the user call rcu_barrier() is asking for subtle bugs.
Therefore, the best approach is to have kmem_cache_destroy() handle
the RCU cleanup, given that this cleanup is for actions taken by
kmem_cache_free(), not by the user.

Well then we are going down to a crappy interface and mixing rcu with slab
semantics. More bugs to follow in the future.

The slab code itself is not referencing the later memory with my patch. It
can only be the user.

Guess we are doing this ... Sigh. Are you going to add support other rcu
versions to slab as well as time permits and as the need arises? Should we
add you as a maintainer? ;-)

Right.

Those are going to be freed without calls to rcu with my patch. The only
reason for earlier rcu frees are user calls to kfree.

Nope the user must follow RCU guidelines when using objects.

I never said that you do not need an rcu_barrier() for this particular
situation? Why suggest such a thing?

The insertion of rcu stuff in the slab code will lead to future bugs since
now the slab logic is tied to the semantics of a particular rcu
implementatin.

Ok then the user already has to deal with the barriers. The API is
inconsistent if you put this into kmem_cache_destroy.

This is already the second bug on this issue. Given the complexity of rcu
it is to be experted that inserting more RCU semantics into the slab
allocators is likely to cause future chains of new features and
bugs in slab allocators.

Now its two rcu_barriers(). What I feared comes true.

The user already has to properly handle barriers and rcu logic in order to
use objects handled with RCU properly. Moreover the user even has to check
that the object is not suddenly checked under it. Its already complex.

I argue that the above is the user's responsibility.  That said, I don't
see why the user would pass a SLAB_DESTROY_BY_RCU object to call_rcu().
So I would want to see an example of this before inflicting a pair
of rcu_barrier() calls on kmem_cache_destroy().

This last is I believe kmem_cache's responsibility.

mm/slab.c has had RCU calls since 2.6.9, so this is not new.

I don't see any point in adding anything resembling SLAB_DESTROY_BY_RCU_BH,
SLAB_DESTROY_BY_RCU_SCHED, or SLAB_DESTROY_BY_SRCU unless and until
someone needs it.  And I most especially don't see the point of adding
(say) SLAB_DESTROY_BY_RCU_BH_SCHED until someone convinces me of the
need for it.  I would prefer to put the energy into further streamlining
the underlying RCU implementation, maybe someday collapsing RCU-BH back
into RCU.  ;-)

We have gotten along fine with only SLAB_DESTROY_BY_RCU for almost
five years, so I think we are plenty fine with what we have.  So, as
you say, "as the need arises".

I don't see any more need to add me as maintainer of slab and friends
than of btrfs, netfilter, selinux, decnet, afs, wireless, or any of a
number of other subsystems that use RCU.

These were the glory years where SLAB_DESTROY_BY_RCU was only used for
anonymous vmas. Now Eric has picked it up for the net subsystem. You may
see the RCU use proliferate.

The kmem_cache_destroy rcu barriers did not matter until
SLAB_DESTROY_BY_RCU spread.

Certainly it is true that increased use of RCU has resulted in new
requirements, which have in turn led to any number of changes over
the years.

Are you saying that people have already asked you for additional
variants of SLAB_DESTROY_BY_RCU?  If so, please don't keep them a secret!
Otherwise, experience indicates that it is best to wait for the new uses,
because they usually aren't quite what one might expect.

No direct request but I have seen the network developers discover these
features and their caching benefits over the last year. It is likely that
they will try to push it into more components of the net subsystem.

So if they push it far enough, they might well decide that they need
a SLAB_DESTROY_BY_RCU_BH, for example.  Looks like seven bits left,
so unless I am missing something, should not be a huge problem should
this need arise.

I'd rather have the call_rcu in the slabs replaced by a function that
can be set by the user. Then we can remove all rcu barriers from the code
and the slabs could be used with any type of rcu functionality.

If the embedded guys are OK with an additional pointer in the slab data
structure, I have no objection to this approach.  I am assuming that we
would use the usual ops-style structure full of pointers to functions
in order to avoid a pair of extra pointers.

This would also allow us to get rid of the ctor pointer in
kmem_cache_create(). We can put it into the same structure.

Sounds good -- that would result in no increase in size.  Could even
add a dtor if people want it.  ;-)  (Sorry, couldn't resist...)
