BUG_ON(page_mapped(page)) in invalidate_inode_pages2_range():
that's interesting, it may relate to another BUG_ON(page_mapped(page))
that's been reported recently.

This is a 2.6.36.1 kernel you're running: any idea what was the first
kernel on which you started seeing such errors?  and what was the last
good kernel on which you ran the same kind of load but saw no problems?

Thanks,
Hugh

At the moment I've downgraded to 2.6.36 - I cannot remember to have
seen this there - which does not need to mean anything, because
workload has changed (several unshared mount/network namespaces chrooted
into unionfs-fuse mounted roots - cool stuff...).

Would you suspect to make 2.6.36 <> 2.6.36.1 a difference here?

Later, when I've results from the test with 2.6.36 of course I'll try
the quick test you suggested.

No, that's unlikely.

Took until now to happen in 2.6.36 - so it is there also. I cannot
really say if it is less frequent in 2.6.36 at the moment, but from
that very limited number of tests (1) it looks like.

Kernel compile 2.6.36.1 with that .page_mkwrite commented out running
now, will reboot really soon now (TM).

OK - that happened very fast again in 2.6.36.1.

Sorry for that tainted kernel, but cannot afford to additionally have
graphics lockups all the time - I've shown that it happens with
untainted kernel also (long run without fault yesterday also was with
nvidia.ko driver).

Until I've another suggestion what to try I'll swich back to 2.6.36 to
see if it really happens less frequent there.

Thats rather complicated, but I'll try. Basically it boils down to:

unshare -n -m /bin/bash
unionfs -o cow,suid,allow_other,max_files=65536 /home/netenv/user1-union=RW:/=RO /home/netenv/user1
mount -n -t proc none /home/netenv/user1/proc
mount -n -t sysfs none /home/netenv/user1/sys
mount -n -t devtmpfs devtmpfs /home/netenv/user1/dev
mount -n -t devpts devpts /home/netenv/user1/dev/pts
chroot /home/netenv/user1 /bin/su - user1

Then run some shell-scripts in this shell running as user1.

Of course there is some more stuff as getting network connectivity in
this new namespace and so on, but I guess thats not important for the
fuse problem.

Then there are some (up to 6 at the moment) more setups like the above
one with different users (user2, user3 and so on) running concurrent.

In some of this setups two or more environments share the same writable
branch, so the files in this environments changed against real root of
the machine are the same, e.g.:

[...]
unionfs -o cow,suid,allow_other,max_files=65536 /home/netenv/commondir=RW:/=RO /home/netenv/user1
[...]

and another one

[...]
unionfs -o cow,suid,allow_other,max_files=65536 /home/netenv/commondir=RW:/=RO /home/netenv/user2
[...]

I observed that unionfs process takes much more cpu power than usual
before fault happens.

 elektra:~ # unionfs --version
unionfs-fuse version: 0.24
FUSE library version: 2.8.5
fusermount version: 2.8.5
using FUSE kernel interface version 7.12

Additional note: Happens also WITHOUT that "two unionfs mounts use the
same branch dir" stuff.

Really seems to happen much more often in 2.6.36.1 than in 2.6.36.

This also happens without that "two unionfs mounts use the same branch

Thanks.

For you the workaround would be to use the "kernel_cache" option which
disables cache invalidation on open.

I'll try to reproduce the BUG on my machine, and if I don't succeed
I'll need som more help from you.

Also could you please send me your kernel .config

> 
> Really seems to happen much more often in 2.6.36.1 than in 2.6.36.

Probably just coincidence.  Sometimes the frequency a bug shows up
depends on code layout (and hence cache layout) differences, which can
vary from compile to compile and even from one boot to the next.

I'll add this patch on my work machine monday morning (happened for me
only on that quadcore, I realize now...) and turn off kernel_cache
again, of course, and let you know what happens.

Thanks.

That's a pretty old bug, isn't it?  5+ years.

I do think this was premature optimisation.  The open-coded lock is
hidden from lockdep so we won't find out if this introduces potential
deadlocks.  It would be better to add a new mutex at least temporarily,
then look at replacing it with a MiklosLock later on, when the code is
bedded in.

At which time, replacing mutexes with MiklosLocks becomes part of a
general "shrink the address_space" exercise in which there's no reason
to exclusively concentrate on that new mutex!


How hard is it to avoid adding a new lock and using an existing one,
presumablt i_mutex?  Because if we can get i_mutex coverage over
unmap_mapping_range() then I suspect all the
vm_truncate_count/restart_addr stuff can go away?

Thanks a lot for working this out, Miklos.

(I don't see any explanation here for the madvise fuzzing page_mapped bug,
but that's not your fault!  I'll have to do my own thinking on that one.)

Did you work out how it came about?  About 2.6.10, I was observing that
unmap_mapping_range() is always called with i_mutex (and usually also
i_alloc_sem) held; whereas around the same time you were adding calls to
unmap_mapping_range() into invalidate_inode_pages2(), which has a much
looser definition than truncation, and does not (necessarily) have
i_mutex held.  We raced.

One fix might be to take i_mutex in invalidate_inode_pages2(); but
I suspect a thorough search would show some calls do already hold it.
Truncation/invalidation have grown a lot more paths since those days,
hard work auditing through them all.  generic_error_remove_page() is
also exceptional to be truncating without i_mutex, but I can never
care very deeply about what might go wrong with hwpoison.

Yes, I very much agree with you there: valiant effort by Miklos to
avoid bloat, but we're better off using a known primitive for now.

invalidate_inode_pages2() calls are the ones to check for that; but I
got tired, and maybe Miklos already found problems with that approach.

That would be lovely, but in fact no: it's guarding against operations on
vmas, things like munmap and mprotect, which can shuffle the prio_tree
when i_mmap_lock is dropped, without i_mutex ever being taken.

However, if we adopt Peter's preemptible mmu_gather patches, i_mmap_lock
becomes a mutex, so there's then no need for any of this (I think Peter
just did a straight conversion here, leaving it in, but it becomes
pointless and would gladly be removed).

I'm still trying to sell that series, so if you see any value in it,
please reply with positive feedback ;-)

Also, the whole vm_truncate_count/restart_addr isn't entirely useless,
its still a lock break which might help with long held locks. Imagine
someone trying to unmap several TB worth of pages at once (not entirely
beyond the realm of possibility today, and we all know tomorrow will be
huge).

Also, bit-spinlocks _suck_.. They're not fair, they're expensive and
like already noted they're hidden from lockdep.

Ideally we should be removing bit-spinlocks from the kernel, not add
more.

Okay, updated patch appended.

One place I know it's hard to get i_mutex coverage is fuse's
d_revalidate.  That's because ->d_revalidate might be called with or
without i_mutex at the discretion of the VFS.

You might ask, why does fuse call invalidate_inode_pages2() from
d_revalidate?  The answer is, fuse does lookup revalidation and
attribute revalidation in one go, and if it finds that the lookup is
still valid but the file contents have changed, then it will need to
invalidate the page cache.

Thanks,
Miklos

Right, pity we weren't stricter about that.

Yes, this looks to me like what is needed for now.

I'd feel rather happier about it if I thought it would also fix
Robert's kernel BUG at /build/buildd/linux-2.6.35/mm/filemap.c:128!
but I've still not found time to explain that one.

Robert, you said yours is usually repeatable in 12 hours - any chance
you could give iknowthis a run with the patch below, to see if it
makes any difference to yours?  (I admit I don't see how it would.)

Thanks,
Hugh

Me neither, all unmap_mapping_range() calls from shmfs are either with
i_mutex or from evict_inode.

Hmm, is there anything preventing remap_file_pages() installing a pte
at an address that unmap_mapping_range() has already processed?

Thanks,

And the page returned by shmem_fault is already locked.

Interesting line of thought: nothing I think, but isn't that okay?

Though its zap_pte can take out present ptes pointing to actual pages,
all populate_range ever installs is non-present pte_file entries: and a
fault on one of those goes through the same checks as in a linear mapping.

(I thought I was going to find an inconsistency with zap_pte_range there,
but no: truncation does not remove pte_file entries beyond end of file,
I remember now thinking that we need to keep SIGBUS-beyond-EOF on them,
instead of letting truncation silently revert those offsets to linear.)

Or am I missing something?
(Well, we know I am, because I've not explained Robert's BUG.)
