2.6.29 pat issue

[Thomas Hellström]

Hi!

The function in include/linux/mm.h:
is_linear_pfn_mapping()

doesn't seem valid to me.

In particular, we have VMAs to graphics devices in which vma->vm_pgoff 
is non-zero (Points to an offset in the drm device node), and the VMA is 
sparsely populated with pfns pointing to uncached discontigous RAM pages.

This causes the X86 PAT code to hit the optimized path when it 
shouldn't, and issue a warning.

Also a question about the philosofy behind this strict checking that all 
PTEs have the same caching attributes: I guess this is only to catch 
bugs in kernel drivers that don't get this right. At the same time, now 
that also user-space VMAs are checked this will probably have a 
significant performance impact. Shouldn't this checking really live 
behind a debug define?

Thanks,
Thomas

Only place where vm_pgoff is getting set for a PFNMAP vma is in
remap_pfn_range() which maps the entire range. vm_insert_pfn() which may
have sparsely populated ranges does not set vm_pgoff. What interface are
you using to map discontig pages, where you are seeing these errors?

The result of not having the caching attribute right can be really bad
as to hang/crash the system. So, having this only in debug is not the
enough, IM0. Kernel has to enforce UC and WC caching types are
consistent at all times. And we also have to keep the indentity map and
other mappings that may be present for that address consistent.

Since vm_pgoff can be nonzero upon every call to a device driver's mmap 
method (It corresponds to the @offset parameter, page shifted, given by 
the user's mmap call), _Any_ VM_PFNMAP vma can practically be assumed to 
be linear by is_linear_pfn_mapping(), and that's an invalid assumption.

In this particular case, We set VM_PFNMAP explicitly in the mmap method 
and use fault() and vm_insert_pfn() to populate the vmas with PTEs 
pointing to private memory pages or io-space depending on where the data 
is currently located. The member vma->vm_pgoff is, as mentioned, set by 
the user-space mmap call, indicating what part of the device address 
space needs to be mapped.

So in the end, we're hitting the WARN_ON_ONCE(1) near line 637 in 
arch/x86/mm/pat.c. We should never have ended up in reserve_pfn_range() 
in the first place.

Indeed, it's crucial to keep the mappings consistent, but failure to do 
so is a kernel driver bug, it should never be the result of invalid user 
data.

There are other more common kernel bugs that can be even worse and hang 
/ crash the system. For example using uninitialized spinlocks, writing 
to kfreed memory etc. There is code in the kernel to detect these as 
well, but this code is behind debug defines.

IMHO checking each vm_insert_pfn() for caching attribute correctness is 
not something that should be enabled by default, due to the CPU 
overhead. Production drivers should never violate this.

OK. Now I understand how you are seeing that warning. I am not what is
the simple way around this. There are no bits available in vm_flags that
we can use to identify linear_pfn_mapping. I don't think you have any
way around in the driver other than using pgoff, in order to do
vm_insert_pfn.
One possible way is to overload some existing flag + PFNMAP to mean
linear pfn map. Will send a patch for this as an RFC soon.

It is not a question of single production driver. There are many
variables here. Different drivers can be mapping the same region. There
can be mapping from /dev/mem. There are also kernel identity and text
mappings. So, any change of cacheability by one driver has to make sure
it is not stepping over some other users of that pte. Kernel has to make
sure different things co-exist in a sane way.

There is an alternative to checking this in each vm_insert_pfn, as long
as mappings are going to be contiguous (even though they may be inserted
individually). As in include/linux/io-mapping.h, we can have a
create_mapping which reserves the entire space, and individual map and
unmap, which doesn't have to check. May be we need a new API for your
use case though...

It easily can be.  Think of an X server mmaping frame buffers. Or other
device bars.

There are cpu errata on almost every cpu in existence that come into play
if you have the cacheabilty attributes wrong on a page.  CPUs have been known
to do very weird things when you hit those errata.  At the best of it you
are no longer running on a deterministic machine, at the worst of it you
crash the cpu.

If it is a problem the implementation should become more efficient.  Userspace
as well as drivers can generate these mappings so even with a perfect driver
you cannot guarantee that someone else does not have that area of memory
mapped differently.

Hmm, Yes  you're right, although I'm still a bit doubtful about RAM pages.

Wait. Now I see what's causing the problems. The code is  assuming that  
VM_PFNMAP vmas never map RAM pages. That's also an invalid assumption. 
See comments in mm/memory.c

So probably the attribute check should be done for the insert_pfn path 
of VM_MIXEDMAP as well. That's not done today.

So there are three distinct bugs at this point:

1) VMAs with VM_PFNMAP are incorrectly assumed to be linear if 
vma->vm_pgoff non-null.
2) VM_PFNMAP VMA PTEs are incorrectly assumed to never point to physical 
RAM.
3) There is no check for the insert_pfn  path of vm_insert_mixed().

OK, So there seems to be a couple of things that can be done for 
performance here:

1) A fastpath for single pages.
2) RAM pages are tracked with a page bit today.
Why not say "all memory backed by a struct page" should be tracked with 
a page bit. Then pfn_valid() could be used instead of page_is_ram(). 
This, combined with 1) should make tracking struct page backed pages 
extremely fast.
3) If vm_insert_pfn() happens to be used on a linear VMA, it looks like 
the whole VMA is being validated for each vm_insert_pfn(), which seems 
extremely inefficient, considering the extensive tests in pagerame_is_ram().

Thanks, Venki. There are a couple of other issues as well. This wasn't 
the root cause of the problem, Pls look at the mail I just sent out.

I think when the issues in the previous mail are fixed, this will in the 
end reduce to a possible performance problem when doing vm_insert_pfn() 
into a contigous range. A create_mapping API could be a way around this.

Patch below will solve (1) above.

About (2), Yes. we can optimize the PAT code if we use struct page to track
PFNMAP as long at memory is backed by a struct page. It has some complications
with refcounting the number of mappings and related things. We are actively
looking at it. About (3), vm_insert_mixed was not used by any in kernel driver,
so, we did not add checks there, with the intention of fixing most commonly
used remap_pfn_range and vm_insert_pfn first.

Below patch should fix the regression upstream. I don't like the way we
overloaded a bit here. But, we don't seem to see any other option.

Subject: [PATCH] VM, x86 PAT: Change implementation of is_linear_pfn_mapping

Use of vma->vm_pgoff to identify the pfnmaps that are fully mapped at
mmap time is broken, as vm_pgoff can also be set when full mapping is
not setup at mmap time.
http://marc.info/?l=linux-kernel&m=123383810628583&w=2

Change the logic to overload VM_NONLINEAR flag along with VM_PFNMAP to
mean full mapping setup at mmap time. This distinction is needed by x86 PAT
code.

Yes, hmm, but how about remap_pfn_range() having an optimized function 
to call into directly, instead of
track_pfn_vma_new?

Cool. Still, there needs to be a check for non-io pages in vm_insert_pfn 
to avoid hitting the WARN_ON_ONCE:
+ if (!pfn_valid(pfn)) //Pfn pointing to a non-ram page.
    track_pfn_vma_new()

Not completely, I think the above check is needed for (2) as well.

No. The idea was to have this flag set, only when full vma is mapped
using remap_pfn_range. In all other cases, insert_pfn or partial region
mapped in remap_pfn_range, we will use the slow path. Having said that,
the patch I had sent here missed one of the conditions. Refreshing the
patch.

About the WARN_ON. I am not completely clear aboue how/why you are
getting the warning. You will only get WARN_ON, if driver is trying to
map actual RAM pages using remap_pfn_range or vm_insert_pfn. That is a
valid warning, I think. If RAM is intended to be mapped, then driver
should be using insert_page or insert_mixed. No? Are you getting the
warning even when you use vm_insert_page or vm_insert_mixed?

No. 
We get the warning when we insert RAM pages using vm_insert_pfn().
Having normal RAM pages backing a PFN papping is a valid thing.

Subject: [PATCH] VM, x86 PAT: Change implementation of is_linear_pfn_mapping

Use of vma->vm_pgoff to identify the pfnmaps that are fully mapped at
mmap time is broken, as vm_pgoff can also be set when full mapping is
not setup at mmap time.
http://marc.info/?l=linux-kernel&m=123383810628583&w=2

Change the logic to overload VM_NONLINEAR flag along with VM_PFNMAP to
mean full mapping setup at mmap time. This distinction is needed by
x86 PAT code.

Yes, this patch should fix the problem. I'm still concerned about the 
overhead of going through the
RAM test for each inserted page.

Why can't a pfn_valid() test be used in vm_insert_pfn()?

Because we may have to track the RAM pages as well in future. We are
changing the e820 RAM check and making it use pfn_valid. But, for that
we have to change more things in tracking of RAM pages. Today we use one
bit in page struct without any refcounting. But, more changes there are
on ts way. This change here should keep the current kernel fine without
any regression.

[PATCH] VM, x86, PAT: Change implementation of is_linear_pfn_mapping

[Pallipadi, Venkatesh]

Use of vma->vm_pgoff to identify the pfnmaps that are fully
mapped at mmap time is broke. vm_pgoff is set by generic mmap
code even for cases where drivers are setting up the mappings
at the fault time.

The problem was originally reported here.
http://marc.info/?l=linux-kernel&m=123383810628583&w=2

Change is_linear_pfn_mapping logic to overload VM_NONLINEAR
flag along with VM_PFNMAP to mean full PFNMAP setup at mmap
time.

I've applied this patch on top of v2.6.29-rc7-143-g99adcd9 [1] and since 
then I've had my system, or rather X/KDE, hang several times. The last 
time the problem seems to have been KDE's kicker. I was running a kernel 
compile in a konsole window and that just continued and finished, but the 
keyboard was completely dead.
I could still ssh in from another box. 'ps' would show the top processes, 
but hang as well at some point (in the middle of listing KDE processes.

The hang was with pat enabled. I've now booted with nopat.

The log shows (full log attached):

From the symptoms I strongly suspect this patch to be the culprit.

Cheers,
FJP

[1] Together with some other patches (mainly Rafael's latest patchset 
for "Rework disabling of interrupts during suspend-resume"), but I doubt 
any of those are related to this issue.

Frans,

Thanks for testing this. I don't seem to reproduce this on any of my
test systems with this patch on either tip or latest git. Do you see the
hang on every boot or once in a while? Are things stable with nopat?

Nothing obvious strikes me with this patch and above OOPs. Can you
please try this patch alone on latest git and check whether you still
see the failures?

Thinking about it a bit more, the usage of VM_NONLINEAR flag in
this patch may be conflicting with some expectation in
mm code, that may be resulting in above oops. Let me
spend some more time on this and get back to you.

The problem only occurs after some time. In the case shown in the log the 
system ran fine for 15 minutes and then triggered the oops.

In another case I was running VirtualBox. It ran fine for some time but 
the system hung when I tried to close the guest system.

> Are things stable with nopat?

Yes. Seen no problems since booting with 'nopat' and done a successful 
suspend/resume. With 'pat' I saw the problem 3 times after a short period 
of use.

OK, Looking more at the code, I now understand how the patch from
yday resulted in the oops you saw. Here goes my nth attempt at solving
this problem. Can you please test this patch.

Thanks,
Venki

Use of vma->vm_pgoff to identify the pfnmaps that are fully
mapped at mmap time is broken. vm_pgoff is set by generic mmap
code even for cases where drivers are setting up the mappings
at the fault time.

The problem was originally reported here.
http://marc.info/?l=linux-kernel&m=123383810628583&w=2

Change is_linear_pfn_mapping logic to overload VM_INSERTPAGE
flag along with VM_PFNMAP to mean full PFNMAP setup at mmap
time.

System has been running stable for almost an hour now with pat enabled, so 
it looks like the problem is solved.

FYI, with early .29 RCs I had the following when running VirtualBox:
kernel: WARNING: at arch/x86/mm/pat.c:620 reserve_pfn_range+0x5b/0x26d()

After be03d9e80220 (which probably fixed that) VirtualBox could no longer 
be loaded at all with pat enabled, but with this patch added VirtualBox 
runs perfectly again.

Thanks Venki.

That's great news :-).

Ingo: considering the history of this patch, can you let this cook in
your tree for a week or so and then push towards upstream-git (and .29
stable if .29 is out by then).

VM, x86, PAT: Change is_linear_pfn_mapping to not use vm_pgoff

Impact: fix false positive PAT warnings - also fix VirtalBox hang

Use of vma->vm_pgoff to identify the pfnmaps that are fully
mapped at mmap time is broken. vm_pgoff is set by generic mmap
code even for cases where drivers are setting up the mappings
at the fault time.

The problem was originally reported here:

 http://marc.info/?l=linux-kernel&m=123383810628583&w=2

Change is_linear_pfn_mapping logic to overload VM_INSERTPAGE
flag along with VM_PFNMAP to mean full PFNMAP setup at mmap
time.

This is really ugly IMO. Either it should be its own bit, or if you want
to reduce usage of bits, then set aside some bits to represent a set of
vma types, and convert existing code over to use that. 

Why not just use another vm_flag for 2.6.29 and earlier (we have 2 left),
then do some flag rationalisation in 2.6.30?

But I do like just avoiding these games entirely and encoding it
explicitly.

Totally agree that this is ugly. But, I didn't like taking away one bit
for such a light usage. VM_INSERTPAGE is hardly ever used in the kernel
(wherever it is used, it is checked along with VM_PFNMAP).

OK. I will resend the patch with taking away one of the available bits.
But, I feel we need to do some multiplexing here, in a clean manner, for
future.

[PATCH] Add a new vm flag to track full pfnmap at mmap

[Pallipadi, Venkatesh]

Add a new vm flag VM_PFN_AT_MMAP to identify a PFNMAP that is
fully mapped with remap_pfn_range. Patch removes the overloading
of VM_INSERTPAGE from the earlier patch.

That is a concern, but I think it makes the patch more intrusive
than a simple fix that might possibly introduce a bug. So for 2.6.29
we have spare flags so can use one of those for the fix.

That would always be appreciated. There are probably several flags that
can go away (eg. VM_RESERVED, VM_INSERTPAGE), others that can be merged
(eg nommu flags with mmu flags), others that can be one scalar value
rather than several binary values etc.

Also, if worst comes to worst, I think we could probably make vm_flags
64-bit on 32-bit compiles to get another 32 bits. Of course I'd rather
not until no other options left for reducing flags ;)

VM, x86, PAT: add a new vm flag to track full pfnmap at mmap

Impact: cleanup

Add a new vm flag VM_PFN_AT_MMAP to identify a PFNMAP that is
fully mapped with remap_pfn_range. Patch removes the overloading
of VM_INSERTPAGE from the earlier patch.
