Hi everybody,

We noticed a crash in Linux dom0 early boot sequence when running over
tboot and Xen. The issue seemed related with a E820 region that tboot is
setting as E820_UNUSABLE. We posted to tboot-devel to understand better
what could be the cause of the kernel panic. This thread can be read
here :
http://sourceforge.net/mailarchive/forum.php?thread_name=51852B26.7070406%40citrix.com&forum_name=tboot-devel

Following Konrad's advice, we took a closer look at arch/x86/xen/setup.c
and found what could be the cause of the kernel panic. I am not familiar
with that part of Xen, so feel free to correct me.

The Xen memory setup code called during early boot is trying to release
chunks of memory in xen_set_identity_and_release for non-RAM regions
(including E820_UNUSABLE). The xen_set_identity_and_release_chunk
function is calling HYPERVISOR_update_va_mapping, which will fail in our
case. As tboot marked that region as being unusable, Xen did not map
those pages and the later call on get_page_from_l1e (arch/x86/mm.c in
Xen code) is returning an error.  As the return value of the hypercall
is not checked in Linux code, xen_set_identity_and_release_chunk
function is carrying on and tries to release the E820_UNUSABLE chunk.
This is apparently messing up some Xen internal memory structures,
resulting in a kernel crash when Linux is initializing its memory mapping.

A possible fix I have tried is to check the return value of
HYPERVISOR_update_va_mapping and if encountering an error, exit from
xen_set_identity_and_release_chunk. This is fixing the kernel panic, but
I am not sure about other implications by that change.

Any ideas about this issue ?

Thanks in advance,
Aurelien

The implications are explained in the git commit that added that:

83d51ab47

    xen/setup: update VA mapping when releasing memory during setup
    
    In xen_memory_setup(), if a page that is being released has a VA
    mapping this must also be updated.  Otherwise, the page will be not
    released completely -- it will still be referenced in Xen and won't be
    freed util the mapping is removed and this prevents it from being
    reallocated at a different PFN.
    
    This was already being done for the ISA memory region in
    xen_ident_map_ISA() but on many systems this was omitting a few pages
    as many systems marked a few pages below the ISA memory region as
    reserved in the e820 map.
    
    This fixes errors such as:
    
    (XEN) page_alloc.c:1148:d0 Over-allocation for domain 0: 2097153 > 2097152
    (XEN) memory.c:133:d0 Could not allocate order=0 extent: id=0 memflags=0 (0 of 17)

So I think it  would be OK to continue with the rest of the function, so something
like this:

diff --git a/arch/x86/xen/setup.c b/arch/x86/xen/setup.c
index 94eac5c..f07ca54 100644
--- a/arch/x86/xen/setup.c

But that looks like a hack as the issue seems to be with the hypervisor?

Without having seen an actual log, this is mostly guessing. My
guessing here is that the kernel is touching an E820_UNUSABLE
page, which the hypervisor rightly rejects (E820_UNUSABLE is
different from there not being any mention of a page in the E820
table - in that case, the page would be assumed to possibly be
an MMIO one, and Xen would generally allow Dom0 to map it).

The issue is triggered by the call to xen_release_chunk, not the
update_va_mapping hypercall. So, I was using a return rather than a break.

This is probably a hack, I just mentioned it to stress the fact that the
kernel crash was caused by the call to xen_release_chunk (and the
decrease_reservation hypercall to Xen I assume).

I was wondering how much xen_release_chunk was relying on the fact that
the previous hypercalls have succeeded. If I understood it correctly,
this is not the case, so there may be a way to make the rest of the code
more robust.

That does not sound quite right to me.  xen_set_identity_and_release()
is releasing RAM pfns that overlap with holes in the machine memory map
and get_page_from_l1e() should always succeed.  The fact that they're
overlapping with something marked as UNUSABLE shouldn't matter since its
no different from any other of the holes.

Is tboot causing Xen to do something weird like leaving holes in dom0's
initial memory allocation?

I would also check what max_pfn_mapped is.  Perhaps it's miscalculated
and were trying to update mappings that don't exit?

get_page_from_l1e() is failing as the call to
page_get_owner_and_reference() is returning NULL. This was caused by
page->count_info being equal to 0, which means the page has not been
allocated, according to the comment in that function. I assume this page
has not been allocated because it is located in a region marked as
E820_UNUSABLE by tboot.

Yes, there are pfns linked to pages that are not allocated.

The region 0000000000975000 - 0000000020000000 has been set to unusable
by tboot.

Calls to update_va_mapping show the following error messages (with mfn
going from 800 to 974):

(XEN) mm.c:911:d0 Error getting mfn 800 (pfn 5555555555555555) from L1

... you certainly mean the range 800000-975000.

Yes, the kernel has no business mapping that region, and the
hypervisor rightly refuses the attempt.

I attached a log of the kernel panic with Xen 4.1.3 and Linux 3.8.10.

Ok, so this is Xen checking the new PTE supplied in the
update_va_mapping hypercall and saying no.

I think there are two things the kernel can do here.

a) Change the type of UNUSABLE regions to RAM.

b) Release pages overlapping UNUSABLE regions, destroy their mapping and
clear/invalidate the region in the p2m.

Option a) is probably the easiest.

Well...  The pfns currently overlapping the machine's UNUSABLE region
are usable RAM and nothing else is the kernel will want to access any
machine address within this region (and evidently can't, even if it
wanted to!).

If it helps, think of it as dom0 taking the pseudo-physical memory map
and putting holes in it to corresponding to interesting bits of the
machine memory map.  UNUSABLE regions aren't interesting so we don't
make holes for them.

We do in the Linux's P2M. We mark them as 1:1, meaning that they the
MFNs we get from the P2M should be the PFN value. And the M2P.. well
that looks to be always 55555.

And that logic looks to be same irregardless if the regions are
E820_RESERVED, E820_UNUSABLE or just MMIO gaps. This is looking at
xen_set_identity_and_release which calls the
xen_set_identity_and_release_chunk (which calls set_phys_range_identity
to set the P2M for 1-1 mapping).

I think I am missing something?
Or when you say 'p2m' you are referring to the hypervisor's direct map?

But then they must not be 1:1 mapped.

But the wrong one - no matter what the kernel changes the region
type to, Xen will still know it as UNUSABLE, and refuse the
mapping.
