dom0 pvops crash

dom0 pvops crash

[Ian Jackson]

See the attached log.  After this first oops, the machine is hosed: a
whole series of similar oopses and userland code has basically stopped
running.

I would run ksymoops but the default build of the pvops kernel as
built by the xen-unstable tree does not apparently include /proc/ksyms (!)

Ian.

Re: dom0 pvops crash

[Keir Fraser]

Info on steps to reproduce this might be useful. The actual crash is in the
swapper: presumably something poisonous happened earlier. The error Xen
reports is essentially that a page of memory that dom0 thinks is nothing
special is in fact in use as a page-table page.

What I did was:

  * install upstream Debian lenny amd64 with development tools
  * build xen-unstable and keep the output

  * install upstream Debian lenny i386 with development tools
  * build xen-unstable and keep the output

  * install upstream Debian lenny i386
  * install the amd64 hypervisor from above
  * install the i386 dom0 kernel and xen toolstack from above
  * reboot into this 32-on-64 environment
  * make an abortive attempt to start a Windows HVM guest (fails
     due to qemu crashing early in the startup, this is a separate
     but unrelated problem)
  * install dev tools
  * attempt to build xen-unstable with `make -j4'

Here's the hacky fix from last summer:
http://lists.xensource.com/archives/html/xen-devel/2009-06/msg00519.html

On my testbox I can trigger that bug just by compiling a kernel in dom0.

CONFIG_HIGHPTE=n is stable for me, while CONFIG_HIGHPTE=y most probably 
makes dom0 crash during a kernel compile.

(dom0 and Xen are 32bit PAE)

Perhaps we need a branch in the git repo that includes just-get-it-working

the trick?

Yeah.  I don't think there's an upstreamable fix, but we can hack

Hm, do you mean 'we don't currently have an upstreamable fix', or 'there is

I'll need to refresh my memory for the precise details, but the basic 
problem is that there's a path in the pagefault code where the kernel 
breaks its own locking rules by kmapping a high pte page without holding 
the pagetable lock.  In the native case this is OK, but it breaks Xen 
because the pte page can be unpinned at that point, but can race with it 
being pinned on another CPU.This can fail in several ways, depending on 
the exact timing: the other CPU's pin could fail because of the writable 
kmapping, or the writable kmap could fail because the page has since 
become pinned.

The brute-force fix is to lock the pte page properly, but given that its 
in the hot part of the pagefault path, and the unlocked access is 
presumably a performance enhancement, I don't think that will fly.

IanC, Pasi, myself and others explored a number of other ways to try and 
fix it in the Xen pvops code, but they all turned out to be very 
expensive, just not work (they just pushed the race around), or require 
new pvops just for this case.  Given that HIGHPTE is generally a bad 
idea and should be deprecated (any machine big enough to need it should 
definitely be running a 64-bit kernel), I've left it on the backburner 
hoping for some inspiration to strike.  So far it has not.

Are you referring to the pte_offset_map() in gup_pte_range()? If so,
would it really be that unacceptable to put a high-page-and-on-Xen
check in there, returning 0 from the function to force using the slow
path?

Just to brainstorm a bit more:

There's no way a kunmap_atomic pvop would be acceptable? it would at
least make the API symmetrical.

What about a hypercall which would set a PTE with the writable bit set
atomically depending on the pinned status of the referenced page? (I
haven't even vaguely thought this idea through).

Is there some way we can disable HIGHPTE at runtime even if
CONFIG_HIGHPTE=y? Looks like that might be relatively self-contained in
pte_alloc_one(). All the actual uses of high PTEs goes through
kmap_atomic which explicitly tests for PageHighmem so by ensuring PTEs
are never high at allocation time we would skip all those paths.
Something like the untested patch below, but not so skanky, obviously.

This last would be nice since it also remove the
crippling-for-virtualisation overhead, so it would potentially benefit
KVM and VMI as well...

Unfortunately distros seem to be using it for their native kernels and
since pvops means they won't have a separate xen kernel I think we need
to figure something out.

We could propose it, but I think we have bigger things to spend our 
capital on.  And I'm not sure it would help:

In theory xen_kmap_atomic could take the pte lock and unmap_atomic could 
release it.  But
kmap_atomic doesn't have enough info be able to take the lock and unmap 
wouldn't either unless we passed it some odd parameters.  And even if we 
did take the lock, the calling kernel code will also attempt to take the 
lock if it actually wants to make a pte change, so we'd have to change 
the logic there.

It doesn't really help because the core issue is the race which changes 
the page state half way through.  If we create a writable mapping, a pin 
on another CPU is going to fail.   We could fix it by locking the pte 
while it is mapped, but then we wouldn't need a new hypercall.

That's a thought.  It could be generally useful too; highpte should only 
be used in extreme circumstances (to prevent ptes from filling most of 
lowmem), not on every system with highmem.   IOW use a generic flag 
rather than make it explicitly Xen-related, then we can set that flag.

Or we could just put a big fat config dependency in.

VMI is a non-issue, and I don't think HIGHPTE is extraordinarily 
expensive on kvm.

We could lobby for them to turn it off.  I wonder if they have a real 
user demand for it these days.  It could only be important for users

I think it could be constructed such that the pin and the new hypercall
collude and do the right thing, somehow... Anyway it doesn't matter, I
think the idea below is much more likely to yield a useful solution.

I think this is the most plausible idea. Need to think about what
criteria would be used to set the flag on native, simply raw RAM size?
i.e. you wouldn't use HIGHPTE on a 4G system, even if CONFIG_HIGHPTE is
enabled, but where would the cut-off be?

Rather than a flag I guess I'd make a pte_gfp variable which could be
modified to suit.

I'd imagine that seemingly random "depends !XEN" would be unpopular

It would be expensive for shadow mode (three traps to update a PTE) but
I guess for EPT/NPT it is around as cheap as on native.

As a separate action to the above that seem like it might be worthwhile.

I guess it is hard for them to judge and so they are relatively
conservative about switching a long standing option off?

A lot of distros have been a bit slow on the uptake with that
configuration.

Well, you could try heuristicing it up, but I suspect a simpler approach 
is just a variable which is enabled by command line and/or config 
option.  HIGHPTE is an arch-independent concept, but the policy for 
defaulting it is arch-specific; on x86 it should almost always be off.

I was thinking the other way around; Xen depends on !HIGHPTE.  But a 
runtime switch would be just as good.

I just tried this patch, but it fails to compile:

arch/x86/mm/pgtable.c: In function 'pte_alloc_one':
arch/x86/mm/pgtable.c:19: error: implicit declaration of function 'is_xen_domain'

I tried grepping around for that function but didn't find it from any header..

IIRC on some kernels it was called just xen_domain(), I'm not sure but I
think my patch was against plain 2.6.32. I think the function (whatever
it is called) also moved around in the headers recently.

For the purposes of testing you could just ignore the conditional part
of the patch and simply drop the __GFP_HIGHMEM altogether.

2.6.32.7 has xen_domain() defined in include/xen/xen.h. Probably
xen_pv_domain() is the correct check though.

Ah, my 2.6.32.7 was actually 2.6.32.7 + Jeremy's next branch which has
the headfile move I mentioend earlier whereas plain 2.6.32.7 does not.

so it looks like you need xen_(|pv_)domain() and asm/xen/hypervisor.h

# grep xen_pv_domain arch/x86/include/asm/xen/hypervisor.h

And now it compiles.. I'm using xen_pv_domain().
I'll do some testing when it's built. 

I also noticed that the HIGHPTE race is much easier to reproduce
on a 2vcpu guest.. where it takes less than 30 mins to happen.

1vcpu guest survived kernel compilation loop for a couple hours OK.

Ok, based on quick testing the patch seems to fix the problem.

details: 2 vcpu guest, 2 GB RAM, 32bit PAE, running 2.6.32.7 with and without the patch.

without the patch: crashes in around 30 minutes.
with the patch: survived over one hour without problems.

I'll continue the compilation loop to make sure it works for real..

The patched PV guest kernel survived around 5 hours of kernel compilation loop 
without problems. I stopped the loop after 5 hours.

Booting back to the non-patched kernel and starting the kernel compilation loop
made it crash in less than 15 minutes.

So this patch definitely helps.

Thanks Pasi, I'll prepare something suitable for upstream.

Even if it worked reliably, CONFIG_HIGHPTE performance would be miserable: It takes an operation that is always going to be slow on any virtualized system (updating PTEs), and pounds the cr*p out of it...

Unfortunately distros tend to enable it on native and with pvops there
is often no separate Xen kernel build where it can be disabled.

I just noticed the default Fedora 12 32bit PAE kernel has CONFIG_HIGHPTE=y.
Running simple "make -j2 bzImage && make -j2 modules" in the guest crashes the kernel.

Some kind of workaround should be made..

Can you try the patch from
<1264613173.16526.97718.camel@zakaz.uk.xensource.com>? (earlier in this
thread).

It's a hack in the form given there but I'm planning to clean it up so
it would be useful to know if the basic concept is sound.

Yeah, sure. I can test that after a couple of days.. some travelling to do now.

Hmm.. so that looks like a 32bit kernel. 
Do you happen to have CONFIG_HIGHPTE=y in .config?

There's a known bug in pv_ops dom0 causing it crash on 32bit PAE
if CONFIG_HIGHPTE=y. There's a hacky patch to fix it on xen-devel archives.. 
(I think Ian Campbell wrote it for testing).

Earlier I thought it was only my hardware triggering it, 
but recently I've noticed it happens for others aswell.

I can trigger this bug on my 32bit PAE testbox by compiling a kernel in dom0..
CONFIG=HIGHPTE=n is stable for me.
