[PATCH] memcg: do not expose uninitialized mem_cgroup_per_node to world

[PATCH] memcg: do not expose uninitialized mem_cgroup_per_node to world

[Igor Mammedov]

Freshly allocated 'mem_cgroup_per_node' list entries must be
initialized before the rest of the kernel can see them. Otherwise
zero initialized list fields can lead to race condition at
mem_cgroup_force_empty_list:
  pc = list_entry(list->prev, struct page_cgroup, lru);
where 'pc' will be something like 0xfffffffc if list->prev is 0
and cause page fault later when 'pc' is dereferenced.

Have you ever seen such a race? I do not see how this could happen.
mem_cgroup_force_empty_list is called only from
mem_cgroup_force_empty_write (aka echo whatever > group/force_empty)
or mem_cgroup_pre_destroy when the group is destroyed. 

The initialization code is, however, called before a group is
given for use AFICS.

I am not saying tha the change is bad, I like it, but I do not think it
is a fix for potential race condition.

Yes I've seen it (RHBZ#700565). It causes random crashes
in virt env ocasionally. It's easier to reproduce if you overcommit
cpu.

Hmm, I have missed that cgroup_create calls create callback for all
subsystems that the group should be attached to. But this shouldn't be
any problem as cgroup_call_pre_destroy (called from cgroup_rmdir) cannot
be called before the directory is actually created. 
cgroup_create_dir is called after cgroup has been created for all
subsystems so the directory entry will show up only after everything is
initialized AFAICS.  So I still do not see how we can race.

Anyway, if you are able to reproduce the problem then I would say that
the problem is somewhere in the generic cgroup code rather than in
memory controler. The patch just papers over a real bug IMO. But I may
be wrong as I am not definitely an expert in the area.

yep. it is. Because list entry fields aren't initialized yet.

No yet.
But vanilla has the same code and down the road may dereference
invalid 'pc' variable too. That's why I posted patch here, theoretically
OOPS could happen.

We have this commit. It's probably another problem.

The trouble manifests itself here:

mem_cgroup_force_empty_list:
   pc = list_entry(list->prev, struct page_cgroup, lru);
when list->prev == 0 we have invalid 'pc' pointer =>  crash

Attached. It's released RHEL6.1 kernel although the problem still exists

yep. it is. Because list entry fields aren't initialized yet.

No yet.
But vanilla has the same code and down the road may dereference
invalid 'pc' variable too. That's why I posted patch here, theoretically
OOPS could happen.

We have this commit. It's probably another problem.

The trouble manifests itself here:

mem_cgroup_force_empty_list:
   pc = list_entry(list->prev, struct page_cgroup, lru);
when list->prev == 0 we have invalid 'pc' pointer =>  crash

Re: [PATCH] memcg: do not expose uninitialized mem_cgroup_per_node to world

[Hiroyuki Kamezawa]

>pc = list_entry(list->prev, struct page_cgroup, lru);

Hmm, I disagree your patch is a fix for mainline. At least, a cgroup
before completion of
create() is not populated to userland and you never be able to rmdir()
it because you can't
find it.

and  mov 0x8(%ebx),%esi

I've looked at vmcore once more and indeed there isn't any parallel task
that touches cgroups code path.
Will investigate if it is xen to blame for incorrect data in place.

Thanks very much for your opinion.

Ah, thank you for input..then panicd at accessing pc->page and "pc"
was 0xfffffff4.
it means list->prev was NULL.

What curious to me is that the fact "list->prev" is NULL.
I can see why you doubt the initialization code ....the list pointer never
contains NULL once it's used....
it smells like memory corruption or some to me. If you have vmcore,
what the problematic mem_cgroup_per_zone(node) contains ?

Hmm, ok, thank you. Then, mem_cgroup_pre_zone[] was initialized once.
In this kind of case, I tend to check slab header of memory object f3446a00,
or check whether f3446a00 is an alive slab object or not.

Hmm, ok, thank you. Then, mem_cgroup_pre_zone[] was initialized once.
In this kind of case, I tend to check slab header of memory object f3446a00,
or check whether f3446a00 is an alive slab object or not.

looks like a really good idea.  But it needs a new changelog and I'd be
a bit reluctant to merge it as it appears that the aptch removes our

So for now I think I'll queue the patch up unchangelogged so the issue

Problem was in rhel's xen hv.

I really don't want to trawl through a lengthy xen bug report and write

We still have no changelog for this patch.  Please send one.

The bug turned out to be Xen specific and this patch just hidden the bug
in Xen.

Appart from a better programming style is there any other reason for
taking it?  If applied it might hide potential bugs when somebody is
touching data too early.

The problem was in incorrect imul instruction emulation in xen and as
consequence incorrect attempt to initialize list at invalid memory location.

If it ever happens and somebody is touching data too early, it would be
a bit easier to diagnose a problem when dereferencing NULL at
mem->info.nodeinfo[node] than wondering at partly initialized
mem_cgroup_per_zone. Aside from that it is purely cosmetic change.

Here is proposed change log:

Subject: Cleanup: memcg: Expose only initialized mem_cgroup_per_node to world

If somebody is touching data too early, it might be easier to diagnose
a problem when dereferencing NULL at mem->info.nodeinfo[node] than
trying to understand why mem_cgroup_per_zone is [un|partly]initialized.

Bahh, I have mixed zero initialized with NULL that would blow up. You
are right of course, sorry for confusion.

The problem was in incorrect imul instruction emulation in xen and as
consequence incorrect attempt to initialize list at invalid memory location.

If it ever happens and somebody is touching data too early, it would be
a bit easier to diagnose a problem when dereferencing NULL at
mem->info.nodeinfo[node] than wondering at partly initialized
mem_cgroup_per_zone. Aside from that it is purely cosmetic change.

Here is proposed change log:

Subject: Cleanup: memcg: Expose only initialized mem_cgroup_per_node to world

If somebody is touching data too early, it might be easier to diagnose
a problem when dereferencing NULL at mem->info.nodeinfo[node] than
trying to understand why mem_cgroup_per_zone is [un|partly]initialized.


Michal will you agree with such commit message?

I really don't want to trawl through a lengthy xen bug report and write
your changelog for you.

We still have no changelog for this patch.  Please send one.

looks like a really good idea.  But it needs a new changelog and I'd be
a bit reluctant to merge it as it appears that the aptch removes our
only known way of reproducing a bug.

So for now I think I'll queue the patch up unchangelogged so the issue
doesn't get forgotten about.

EDI on the first iteration should be 0 however it is a88c8840 according to Oops
dump and looking at -0x18(%ebp) in core shows 0 as it should be:

crash>  x/xw 0xf201deb4-0x18
0xf201de9c:     0x00000000

so it looks like EDI is incorrectly restored by Xen or at the moment when 0xc080b948
was executed -0x18(%ebp) had that weird value.

It is possible that invalid EDI value and following

0xc080b950<mem_cgroup_create+224>:     lea    (%edi,%edx,8),%esi

<https://bugzilla.redhat.com/show_bug.cgi?id=700565#c36>lead to some 
accessible page and writes

0xc080b95f<mem_cgroup_create+239>:     mov    %eax,(%ebx,%esi,1)
0xc080b962<mem_cgroup_create+242>:     mov    %eax,0x4(%eax)

silently go to that page. Than after init lists loop it uses correct pn offset from
-0x14(%ebp) and initialises the rest fields of structure on the correct page.

                 mz->usage_in_excess = 0;
                 mz->on_tree = false;
                 mz->mem = mem;

0xc080b967<mem_cgroup_create+247>:     mov    -0x14(%ebp),%eax<-

0xc080b990<mem_cgroup_create+288>:     jne    0xc080b948

which could lead to the 0-ed list entries of the first zone
and the originally reported Oops in mem_cgroup_force_empty.
Afterwards it looks like:

0xc080b985<mem_cgroup_create+277>:     addl   $0x1,-0x18(%ebp)

-0x18(%ebp) is read correctly and the rest of 3 mz entries are initialized as
expected.

So question is why and how
0xc080b948<mem_cgroup_create+216>:     imul   $0x7c,-0x18(%ebp),%edi
may be screwed up

PS:
However, memory search for the went astray writes of the first entry
i.e. sequesnce f3446a00 f3446a00 in a couple of vmcores didn't give
any positive results.

0xc080b96a<mem_cgroup_create+250>:     movl   $0x0,0x6c(%eax)

EDI on the first iteration should be 0 however it is a88c8840 according to Oops
dump and looking at -0x18(%ebp) in core shows 0 as it should be:

crash>  x/xw 0xf201deb4-0x18
0xf201de9c:     0x00000000

so it looks like EDI is incorrectly restored by Xen or at the moment when 0xc080b948
was executed -0x18(%ebp) had that weird value.

It is possible that invalid EDI value and following

0xc080b950<mem_cgroup_create+224>:     lea    (%edi,%edx,8),%esi

<https://bugzilla.redhat.com/show_bug.cgi?id=700565#c36>lead to some 
accessible page and writes

0xc080b95f<mem_cgroup_create+239>:     mov    %eax,(%ebx,%esi,1)
0xc080b962<mem_cgroup_create+242>:     mov    %eax,0x4(%eax)

silently go to that page. Than after init lists loop it uses correct pn offset from
-0x14(%ebp) and initialises the rest fields of structure on the correct page.

                 mz->usage_in_excess = 0;
                 mz->on_tree = false;
                 mz->mem = mem;

0xc080b967<mem_cgroup_create+247>:     mov    -0x14(%ebp),%eax<-
0xc080b96a<mem_cgroup_create+250>:     movl   $0x0,0x6c(%eax)
0xc080b971<mem_cgroup_create+257>:     movl   $0x0,0x70(%eax)
0xc080b978<mem_cgroup_create+264>:     movb   $0x0,0x74(%eax)
0xc080b97c<mem_cgroup_create+268>:     mov    -0x1c(%ebp),%edx
0xc080b97f<mem_cgroup_create+271>:     mov    %edx,0x78(%eax)
0xc080b982<mem_cgroup_create+274>:     add    $0x7c,%eax
0xc080b985<mem_cgroup_create+277>:     addl   $0x1,-0x18(%ebp)
0xc080b989<mem_cgroup_create+281>:     cmpl   $0x4,-0x18(%ebp)
0xc080b98d<mem_cgroup_create+285>:     mov    %eax,-0x14(%ebp)
0xc080b990<mem_cgroup_create+288>:     jne    0xc080b948

which could lead to the 0-ed list entries of the first zone
and the originally reported Oops in mem_cgroup_force_empty.
Afterwards it looks like:

0xc080b985<mem_cgroup_create+277>:     addl   $0x1,-0x18(%ebp)

-0x18(%ebp) is read correctly and the rest of 3 mz entries are initialized as
expected.

So question is why and how
0xc080b948<mem_cgroup_create+216>:     imul   $0x7c,-0x18(%ebp),%edi
may be screwed up

PS:
However, memory search for the went astray writes of the first entry
i.e. sequesnce f3446a00 f3446a00 in a couple of vmcores didn't give
any positive results.

Possible shadow bug (was: Re: [PATCH] memcg: do not expose uninitialized mem_cgroup_per_node to world)

This is a comment from a previous email in the thread:

it makes me think that it is a shadow pagetables bug; see details below.
You can find more details on it following this thread on the lkml.

Possible shadow bug (was: Re: [PATCH] memcg: do not expose uninitialized mem_cgroup_per_node to world)

[Stefano Stabellini]

CC'ing xen-devel and Tim.

This is a comment from a previous email in the thread:

it makes me think that it is a shadow pagetables bug; see details below.
You can find more details on it following this thread on the lkml.

Possible shadow bug (was: Re: [PATCH] memcg: do not expose uninitialized mem_cgroup_per_node to world)

[Stefano Stabellini]

CC'ing xen-devel and Tim.

This is a comment from a previous email in the thread:

it makes me think that it is a shadow pagetables bug; see details below.
You can find more details on it following this thread on the lkml.

Oh dear.  I'm having a look at the linux code now to try and understand

you're willing to try recompiling Xen with some small patches that

transiently going to the wrong frame, it turned out to be caused by
32-bit pagetable-handling code writing a PAE PTE with a single 64-bit
write (which is not atomic on x86-32), and the TLB happening to see the
intermediate, half-written entry.  I doubt that there's any bug like
that in linux, though, or we'd surely have seen it before now.

Oh dear.  I'm having a look at the linux code now to try and understand

It's rhel5.6 xen. I've tried to test on SLES 11 that has 4.0.1 xen, however
wasn't able to reproduce problem. (I'm not sure if hap was turned off in 
this
case). More detailed info can be found at RHBZ#700565

The best way to be sure whether HAP is in use is to connect to the
serial line, hit ^A^A^A to switch input to Xen, and hit 'q' to dump
per-domain state.  The printout for the guest domain should either say 
"paging assistance: shadow refcounts translate external"
or 
"paging assistance: hap refcounts translate external".

(If you don't have serial you can get the same info by running 
"xm debug-keys q" and then "xm dmesg" to read the output.)

Actually, looking at the disassembly you posted, it looks more like it
might be an emulator bug in Xen; if Xen finds itself emulating the IMUL
instruction and either gets the logic wrong or does the memory access
wrong, it could cause that failure.  And one reason that Xen emulates
instructions is if the memory operand is on a pagetable that's shadowed
(which might be a page that was recently a pagetable). 

ISTR that even though the RHEL xen reports a 3.0.x version it has quite
a lot of backports in it.  Does it have this patch?

Based on a quick scrobble through the CentOS 5.6 SRPMs it looks like a
3.1.0 hypervisor with a bunch of extra patches, but not this one.  This
is very likely the cause of the crash in mem_cgroup_create(), and
probably the corruptions too.  That would explain why they didn't happen
on a 4.0.x SLES11 Xen, but not really why the original patch in this
thread made it go away.

Maybe it changes timing so that imul is executed with correct memory 
content?
Putting extra printk inside zone loop or flushing tlb before it also 
make problem
go away. Or may be problem just becomes invisible and memory is corrupted at
another place.

Putting extra printk inside zone loop or flushing tlb before it also 
make problem
go away. Or may be problem just becomes invisible and memory is corrupted at

Based on a quick scrobble through the CentOS 5.6 SRPMs it looks like a
3.1.0 hypervisor with a bunch of extra patches, but not this one.  This
is very likely the cause of the crash in mem_cgroup_create(), and
probably the corruptions too.  That would explain why they didn't happen
on a 4.0.x SLES11 Xen, but not really why the original patch in this
thread made it go away.

The best way to be sure whether HAP is in use is to connect to the
serial line, hit ^A^A^A to switch input to Xen, and hit 'q' to dump
per-domain state.  The printout for the guest domain should either say 
"paging assistance: shadow refcounts translate external"
or 
"paging assistance: hap refcounts translate external".

(If you don't have serial you can get the same info by running 
"xm debug-keys q" and then "xm dmesg" to read the output.)

Actually, looking at the disassembly you posted, it looks more like it
might be an emulator bug in Xen; if Xen finds itself emulating the IMUL
instruction and either gets the logic wrong or does the memory access
wrong, it could cause that failure.  And one reason that Xen emulates
instructions is if the memory operand is on a pagetable that's shadowed
(which might be a page that was recently a pagetable). 

ISTR that even though the RHEL xen reports a 3.0.x version it has quite
a lot of backports in it.  Does it have this patch?

It's rhel5.6 xen. I've tried to test on SLES 11 that has 4.0.1 xen, however
wasn't able to reproduce problem. (I'm not sure if hap was turned off in 
this
case). More detailed info can be found at RHBZ#700565

Possible shadow bug (was: Re: [PATCH] memcg: do not expose uninitialized mem_cgroup_per_node to world)

[Stefano Stabellini]

CC'ing xen-devel and Tim.

This is a comment from a previous email in the thread:

it makes me think that it is a shadow pagetables bug; see details below.
You can find more details on it following this thread on the lkml.

it has all zeros except for last field:

It looks like a very targeted corruption of the first zone except of
the last field, while the second zone and the rest are perfectly
normal (i.e. have empty initialized lists).


PS:
It most easily reproduced only on xen hvm 32bit guest under heavy
vcpus contention for real cpus resources (i.e. I had to overcommit
cpus and run several cpu hog tasks on host to make guest crash on
reboot cycle).
And from last experiments, crash happens only on on hosts that
doesn't have hap feature or if hap is disabled in hypervisor.

Ah, thank you for input..then panicd at accessing pc->page and "pc"
was 0xfffffff4.
it means list->prev was NULL.

What curious to me is that the fact "list->prev" is NULL.
I can see why you doubt the initialization code ....the list pointer never
contains NULL once it's used....
it smells like memory corruption or some to me. If you have vmcore,
what the problematic mem_cgroup_per_zone(node) contains ?

Hmm, I disagree your patch is a fix for mainline. At least, a cgroup
before completion of
create() is not populated to userland and you never be able to rmdir()
it because you can't
find it.

Looks like one pointer underflow from NULL.

I realize that the issue is hard to reproduce but have you tried it with
the .39 vanilla?
Or at least try it with fce66477 (just a blind shot).

And yes, I agree that it is rather a workaround than real fix of race
condition which shouldn't exist in the first place. But giving my very
limited knowledge of cgroups and difficulty to reproduce the crash
after adding/enabling additional debugging, that patch is what
can fix the problem for now.
And maybe more experienced guys will look at the code and fix it
in the right way. Well at least I hope for that.
