CONFIG_VMAP_STACK, on-stack struct, and wake_up_bit

CONFIG_VMAP_STACK, on-stack struct, and wake_up_bit

[Andreas Gruenbacher]

Hi,

CONFIG_VMAP_STACK has broken gfs2 and I'm trying to figure out what's
going on. What I'm seeing is the following: on a fresh gfs2 filesystem
created with:

  mkfs.gfs2 -p lock_nolock $DEVICE

I get the following BUG with 4.9-rc2, CONFIG_VMAP_STACK and
CONFIG_DEBUG_VIRTUAL turned on:

  kernel BUG at arch/x86/mm/physaddr.c:26!

Stack of kernel thread:

  __phys_addr(x)
  bit_waitqueue(word, bit)
  wake_up_bit(word = &gh->gh_iflags, bit = HIF_WAIT)
  gfs2_holder_wake(gh)

The gh here is on the stack of another kernel thread:

  static int fill_super(struct super_block *sb, struct gfs2_args
*args, int silent)
  {
    struct gfs2_holder mount_gh;
  }

Which is waiting on the bit with:

  wait_on_bit(&gh->gh_iflags, HIF_WAIT, TASK_UNINTERRUPTIBLE)

Is accessing a struct on another kernel thread's stack no longer working?

Thanks,
Andreas

It's this:

const struct zone *zone = page_zone(virt_to_page(word));

If the stack is vmalloced, then you can't find the page's zone like
that.  We could look it up the slow way (ick!), but maybe another
solution would be to do:

wait_queue_head_t *wait_table;
if (virt_addr_valid(word))
  wait_table = page_zone(virt_to_page(word))->wait_table;
else
  wait_table = funny_wait_table;

where funny_wait_table is an extra wait table just for funny addresses.

This will scale poorly on very large NUMA systems where many zones are
simultaneously using on-stack wait_bit bits, but I suspect this is a
very rare use case.

That part should be fine.

Christ. It's that damn bit-wait craziness again with the idiotic zone lookup.

I complained about it a couple of weeks ago for entirely unrelated
reasons: it absolutely sucks donkey ass through a straw from a cache
standpoint too. It makes the page_waitqueue() thing very expensive, to
the point where it shows up as taking up 3% of CPU time on a real
load.,

PeterZ had a patch that fixed most of the performance trouble because
the page_waitqueue is actually never realistically contested, and by
making the bit-waiting use *two* bits you can avoid the slow-path cost
entirely.

But here we have a totally different issue, namely that we want to
wait on a virtual address.

Quite frankly, I think the solution is to just rip out all the insane
zone crap. The most important use (by far) for the bit-waitqueue is
for the page locking, and with the "use a second bit to show
contention", there is absolutely no reason to try to do some crazy
per-zone thing. It's a slow-path that never matters, and rather than
make things scale well, the only thing it does is to pretty much
guarantee at least one extra cache miss.

Adding MelG and the mm list to the cc (PeterZ was already there) here
just for the heads up.

IOW, something like the attached.

Advantage:

 - just look at the number of garbage lines removed!  21
insertions(+), 182 deletions(-)

 - it will actually speed up even the current case for all common
situations: no idiotic extra indirections that will take extra cache
misses

 - because the bit_wait_table array is now denser (256 entries is
about 6kB of data on 64-bit with no spinlock debugging, so ~100
cachelines), maybe it gets fewer cache misses too

 - we know how to handle the page_waitqueue contention issue, and it
has nothing to do with the stupid NUMA zones

The only case you actually get real page wait activity is IO, and I
suspect that hashing it out over ~100 cachelines will be more than
sufficient to avoid excessive contention, plus it's a cache-miss vs an
IO, so nobody sane cares.

The only reason it did that insane per-zone thing in the first place
that right now we access those wait-queues even when we damn well
shouldn't, and we have the solution for that.

Guys, holler if you hate this, but I think it's realistically the only
sane solution to the "wait queue on stack" issue.

Oh, and the patch is obviously entirely untested. I wouldn't want to
ruin my reputation by *testing* the patches I send out. What would be
the fun in that?

So I tested it. It compiles, and it actually also solves the
performance problem I was complaining about a couple of weeks ago with
"unlock_page()" having an insane 3% CPU overhead when doing lots of
small script ("make -j16 test" in the git tree for those that weren't
involved in the original thread three weeks ago).

So quite frankly, I'll just commit it. It should fix the new problem
with gfs2 and CONFIG_VMAP_STACK, and I see no excuse for the crazy
zone stuff considering how harmful it is to everybody else.

I expect that when the NUMA people complain about page locking (if
they ever even notice), PeterZ will stand up like the hero he is, and

I can definitely wait an hour, it would be lovely to see more testing.
Especially if you have a NUMA machine and an interesting workload.

And if you actually have that NUMA machine and a load that shows the
page_waietutu effects, it would also be lovely if you can then
_additionally_ test the patch that PeterZ wrote a few weeks ago, it
was on the mm list about a month ago:

Sorry. I guess I underestimated the time it takes to build a kernel
on my test box. It will take a little longer, but it's compiling now.

Hmm. Looks like a completely independent issue from the patch. Did you
try booting that machine without the patch?

Ok, similar issue, I think - passing a non-1:1 address to __phys_addr().

But the call trace has nothing to do with gfs2 or the bitlocks:

I think this might be the

        cont    = __pa(container);

line in save_microcode_in_initrd_amd().

I see that Borislav is busy with some x86/microcode patches, I suspect
he already hit this. Adding Borislav to the cc.

Can you re-try without the AMD microcode driver for now? This seems to
be a separate issue from the gfs2 one.

I think this might be the

        cont    = __pa(container);

line in save_microcode_in_initrd_amd().

I see that Borislav is busy with some x86/microcode patches, I suspect
he already hit this. Adding Borislav to the cc.

Can you re-try without the AMD microcode driver for now? This seems to
be a separate issue from the gfs2 one.

Hmm, I guess that fires because that container thing is a static pointer
so it is >= PAGE_OFFSET. But I might be wrong, it is too late here for
brain to work.

In any case, looking at his Code:

   0:   48 89 f8                mov    %rdi,%rax
   3:   72 28                   jb     0x2d
   5:   48 2b 05 7b a0 dc 00    sub    0xdca07b(%rip),%rax        # 0xdca087
   c:   48 05 00 00 00 80       add    $0xffffffff80000000,%rax
  12:   48 39 c7                cmp    %rax,%rdi
  				^^^^^^^^^^^^^^^^

it could be this comparison here:

RAX: fffff39132a822fc, RDI: ffff8800b2a822fc

  15:   72 14                   jb     0x2b

... which sends us to the UD2.

  17:   0f b6 0d 6a 75 ee 00    movzbl 0xee756a(%rip),%ecx        # 0xee7588

We might end up at 0x2b from here too - that's !phys_addr_valid(x) - but
ECX is 0 while it should be 36...

  1e:   48 89 c2                mov    %rax,%rdx
  21:   48 d3 ea                shr    %cl,%rdx
  24:   48 85 d2                test   %rdx,%rdx
  27:   75 02                   jne    0x2b
  29:   5d                      pop    %rbp
  2a:   c3                      retq   
  2b:*  0f 0b                   ud2             <-- trapping instruction
  2d:   48 03 05 7b 5b da 00    add    0xda5b7b(%rip),%rax        # 0xda5baf
  34:   48 81 ff ff ff ff 3f    cmp    $0x3fffffff,%rdi
  3b:   76 ec                   jbe    0x29
  3d:   0f 0b                   ud2    
  3f:   0f                      .byte 0xf

But again, I could be already sleeping and this could be me talking in
my sleep so don't take it too seriously.

In any case, this code was flaky and fragile for many reasons and it is
why this whole wankery is gone in the microcode loader now.

> Can you re-try without the AMD microcode driver for now?

Yeah, just boot with "dis_ucode_ldr".

Btw, can you send me your .config so that I can try to reproduce?

I'm assuming you're booting latest Linus' tree on it?

I'd need to take care of this for 4.9.

Attached, but as Linus suggested, I turned off the AMD microcode driver,
so it should be the same if you turn it back on. If you want, I can
do it and re-send so you have a more pristine .config. Let me know.
 
| I'm assuming you're booting latest Linus' tree on it?

Yes.

Without the AMD microcode driver, the kernel boots just fine (I knew
it wasn't GFS2 because my root partition is ext4).

I'm doing some basic smoke tests on GFS2, but it seems to be running
just fine with Linus's aforementioned patch. I'll see if I can push it
a little harder.

Thanks, but I was able to reproduce in a VM.

Here's a fix which works here - I'd appreciate it if you ran it and
checked the microcode was applied correctly, i.e.:

$ dmesg | grep -i microcode

before and after the patch. Please paste that output in a mail too.

Thanks!

Subject: [PATCH] x86/microcode/AMD: Fix more fallout from CONFIG_RANDOMIZE_MEMORY

We needed the physical address of the container in order to compute the
offset within the relocated ramdisk. And we did this by doing __pa() on
the virtual address.

However, __pa() does checks whether the physical address is within
PAGE_OFFSET and __START_KERNEL_map - see __phys_addr() - which fail
if we have CONFIG_RANDOMIZE_MEMORY enabled: we feed a virtual address
which *doesn't* have the randomization offset into a function which uses
PAGE_OFFSET which *does* have that offset.

This makes this check fire:

	VIRTUAL_BUG_ON((x > y) || !phys_addr_valid(x));
			^^^^^^

due to the randomization offset.

The fix is as simple as using __pa_nodebug() because we do that
randomization offset accounting later in that function ourselves.

Hi Borislav,

Sorry it's taken me so long. I've been having issues.
I couldn't recreate that first boot failure, even using .config.old,

Hmm, so it could also depend on the randomized offset as it is getting
generated anew each boot. So you could try to boot a couple of times
to see if the randomized offset is generated just right for the bug
condition to match.

I mean, it would be great if you try a couple times but even if you're
unsuccessful, that's fine too - the fix is obviously correct and I've
confirmed that it boots fine in my VM here.

Hi Boris,

I rebooted the machine with and without your patch, about 15 times each,
and no failures. Not sure why I got it the first time. Must have been a one-off.

x86/microcode/AMD: Fix more fallout from CONFIG_RANDOMIZE_MEMORY=y

We needed the physical address of the container in order to compute the
offset within the relocated ramdisk. And we did this by doing __pa() on
the virtual address.

However, __pa() does checks whether the physical address is within
PAGE_OFFSET and __START_KERNEL_map - see __phys_addr() - which fail
if we have CONFIG_RANDOMIZE_MEMORY enabled: we feed a virtual address
which *doesn't* have the randomization offset into a function which uses
PAGE_OFFSET which *does* have that offset.

This makes this check fire:

	VIRTUAL_BUG_ON((x > y) || !phys_addr_valid(x));
			^^^^^^

due to the randomization offset.

The fix is as simple as using __pa_nodebug() because we do that
randomization offset accounting later in that function ourselves.

x86/microcode/AMD: Fix more fallout from CONFIG_RANDOMIZE_MEMORY=y

We needed the physical address of the container in order to compute the
offset within the relocated ramdisk. And we did this by doing __pa() on
the virtual address.

However, __pa() does checks whether the physical address is within
PAGE_OFFSET and __START_KERNEL_map - see __phys_addr() - which fail
if we have CONFIG_RANDOMIZE_MEMORY enabled: we feed a virtual address
which *doesn't* have the randomization offset into a function which uses
PAGE_OFFSET which *does* have that offset.

This makes this check fire:

	VIRTUAL_BUG_ON((x > y) || !phys_addr_valid(x));
			^^^^^^

due to the randomization offset.

The fix is as simple as using __pa_nodebug() because we do that
randomization offset accounting later in that function ourselves.

IO wait activity is not all that matters. We hit the lock/unlock paths
during a lot of operations like reclaim.

False sharing is possible with either the new or old scheme so it's
irrelevant. There will be some remote NUMA cache misses which may be made
worse by false sharing. In the reclaim case, the bulk of those are hit
by kswapd. Kswapd itself doesn't care but there may be increased NUMA
traffic. By the time you hit direct reclaim, a remote cache miss is not
going to be the end of the world.

Hate? No.

It's not clear cut that NUMA remote accesses will be a problem. A remote
cache miss may or may not be more expensive than multiple calculations,
virt->page calculations and chasing pointers to lookup the zone and the
table. It's multiple potential local misses versus one remote.

Even if NUMA conflicts are a problem then 256 entries gives 96 cache
lines. For pages only, the hash routine could partition table space into
max(96, nr_online_nodes) partitions. It wouldn't be perfect as wait_table_t
does not align well with cache line sizes so there would be collisions
on the boundary but it'd be close enough. It would require page_waitqueue
use a different hashing function so it's not simple but it's possible if
someone is sufficiently motivated and found a workload that matters.

There is some question whether the sizing will lead to more collisions and
spurious wakeups. There is no way to predict how much of an issue that is
but I suspect a lot of those happen during reclaim anyway. If collisions
are a problem then the table could be dynamically sized in the similar
way the inode and dcache hash tables are.

I didn't test this as I don't have a machine available right now.  The bulk
of what you removed was related to hotplug but the result looks hotplug safe.
So I've only Two minor nits only and a general caution to watch for increased
collisions and spurious wakeups with a minor caution about remote access
penalties.

zone_is_initialized is mostly the domain of hotplug. A potential cleanup
is to use a page flag and shrink the size of zone slightly. Nothing to

I doubt we do.

Yes, we hit the lock/unlock itself, but do we hit the *contention*?

The current code is nasty, and always ends up touching the wait-queue
regardless of whether it needs to or not, but we have a fix for that.

With that fixed, do we actually get contention on a per-page basis?
Because without contention, we'd never actually look up the wait-queue
at all.

I suspect that without IO, it's really really hard to actually get
that contention, because things like reclaim end up looking at the LRU
queue etc wioth their own locking, so it should look at various
individual pages one at a time, not have multiple queues look at the
same page.

I really did that to make it very obvious that there was no semantic
change. I just set the "initialized" flag in the same place where it
used to initialize the wait_table, so that this:

>>  static inline bool zone_is_initialized(struct zone *zone)

Admittedly I didn't clear it when the code cleared the wait_table
pointer, because that _seemed_ a non-issue - the zone will remain
initialized until it can't be reached any more, so there didn't seem
to be an actual problem there.

I considered that, but decided that "minimal patch" was better. Plus,
with that bit_waitqueue() actually also being used for the page
locking queues (which act _kind of_ but not quite, like a bitlock),
the bit_wait_table is actually more core than just the bit-wait code.

In fact, I considered just renaming it to "hashed_wait_queue", because
that's effectively how we use it now, rather than being particularly
specific to the bit-waiting. But again, that would have made the patch
bigger, which I wanted to avoid since this is a post-rc2 thing due to
the gfs2 breakage.

I considered that, but decided that "minimal patch" was better. Plus,
with that bit_waitqueue() actually also being used for the page
locking queues (which act _kind of_ but not quite, like a bitlock),
the bit_wait_table is actually more core than just the bit-wait code.

In fact, I considered just renaming it to "hashed_wait_queue", because
that's effectively how we use it now, rather than being particularly
specific to the bit-waiting. But again, that would have made the patch
bigger, which I wanted to avoid since this is a post-rc2 thing due to
the gfs2 breakage.

Reclaim would have to running parallel to migrations, faults, clearing
write-protect etc. I can't think of a situation where a normal workload
would hit it regularly and/or for long durations.

No objection. Shuffling it around does not make it obviously better in
any way.

In the meantime, a machine freed up. FWIW, it survived booting on a 2-socket
and about 20 minutes of bashing on reclaim paths from multiple processes
to beat on lock/unlock. I didn't do a performance comparison or gather
profile data but I wouldn't expect anything interesting from profiles
other than some cycles saved.

Yup, that's the one. I think you tested it. In fact, I'm sure you did,
because I remember seeing performance numbers from  you ;)

So yes, I'd expect my patch on its own to quite possibly regress on
NUMA systems (although I wonder how much), but I consider PeterZ's
patch the fix to that, so I wouldn't worry about it.

Yeah and the figures were fine. IIRC, 32-bit support was the main thing
that was missing but who cares, 32-bit is not going to have the NUMA issues
in any way that matters.

I doubt it's a lot. Even if it does, it's doesn't matter because it's a
functional fix.

I was waiting for you guys to hash out the 32bit issue. But if we're now
OK with having this for 64bit only, I can certainly look at doing a new
version.

I'll have to look at fixing Alpha's bitops for that first though,
because as is that patch relies on atomics to the same word not needing
ordering, but placing the contended/waiters bit in the high word for
64bit only sorta breaks that.

Hurm, we could of course play games with the layout, the 64bit only
flags don't _have_ to be at the end.

Something like so could work I suppose, but then there's a slight
regression in the page_unlock() path, where we now do an unconditional
spinlock; iow. we loose the unlocked waitqueue_active() test.

We could re-instate this with an #ifndef CONFIG_NUMA I suppose.. not
pretty though.

Also did the s/contended/waiters/ rename per popular request.

I was waiting for you guys to hash out the 32bit issue. But if we're now
OK with having this for 64bit only, I can certainly look at doing a new
version.

I'll have to look at fixing Alpha's bitops for that first though,
because as is that patch relies on atomics to the same word not needing
ordering, but placing the contended/waiters bit in the high word for
64bit only sorta breaks that.

Hurm, we could of course play games with the layout, the 64bit only
flags don't _have_ to be at the end.

Something like so could work I suppose, but then there's a slight
regression in the page_unlock() path, where we now do an unconditional
spinlock; iow. we loose the unlocked waitqueue_active() test.

We could re-instate this with an #ifndef CONFIG_NUMA I suppose.. not
pretty though.

Also did the s/contended/waiters/ rename per popular request.

I see the problem assuming you're referring to the requirement that locked
and waiter bits are on the same word. Without it, you need a per-arch helper
that forces ordering or takes a spinlock. I doubt it's worth the trouble.

I can't convince myself it's worthwhile. At least, I can't see a penalty
of potentially moving one of the two bits to the high word. It's the
same cache line and the same op when it matters.

I don't see why it should be NUMA-specific even though with Linus'
patch, NUMA is a concern. Even then, you still need a 64BIT check
because 32BIT && NUMA is allowed on a number of architectures.

Otherwise, nothing jumped out at me but glancing through it looked very
similar to the previous patch.

I'm having trouble connecting these here two paragraphs. Or were you
replying to something else?

So the current unlock code does:

  wake_up_page()
    if (waitqueue_active())
      __wake_up() /* takes waitqueue spinlocks here */

While the new one does:

  spin_lock(&q->lock);
  if (waitqueue_active()) {
    __wake_up_common()
  }
  spin_unlock(&q->lock);

Which is an unconditional atomic op (which go for about ~20 cycles each,
when uncontended).

Oh, I thought we killed 32bit NUMA and didn't check. I can make it
CONFIG_64BIT and be done with it. s/CONFIG_NUMA/CONFIG_64BIT/ on the
patch should do :-)

Right, all the difference was in the bit being conditional and having a
different name.

Ok, we were thinking about different things but I'm not sure I get your
concern. With your patch, in the uncontended case we check the waiters
bit and if there is no contention, we carry on. In the contended case,
the lock is taken. Given that contention is likely to be due to IO being
completed, I don't think the atomic op on top is going to make that much
of a difference.

About the only hazard I can think of is when unrelated pages hash to the
same queue and so there is an extra op for the "fake contended" case. I
don't think it's worth worrying about given that a false contention and
atomic op might hurt some workload but the common case is avoiding a

Ok, we were thinking about different things but I'm not sure I get your
concern. With your patch, in the uncontended case we check the waiters
bit and if there is no contention, we carry on. In the contended case,
the lock is taken. Given that contention is likely to be due to IO being
completed, I don't think the atomic op on top is going to make that much
of a difference.

About the only hazard I can think of is when unrelated pages hash to the
same queue and so there is an extra op for the "fake contended" case. I
don't think it's worth worrying about given that a false contention and
atomic op might hurt some workload but the common case is avoiding a
lookup.

I got mine working too. Haven't removed the bitops barrier (that's
for another day), or sorted the page flags in this one. But the core
code is there.

It's a bit more intrusive than your patch, but I like the end result
better. It just stops using the generic bit waiter code completely
and uses its own keys. Ends up being making things easier, and we
could wait for other page details too if that was ever required.

It uses the same wait bit logic for all page waiters.
It keeps PageWaiters manipulation entirely under waitqueue lock, so no
additional data races beyond existing unlocked waitqueue_active tests.
And it checks to clear the waiter bit when no waiters for that page are
in the queue, so hash collisions with long waiters don't end up dragging
us into the slowpath always.

Also didn't uninline unlock_page yet. Still causes some text expansion,
but we should revisit that.

Thanks,
Nick
