Under aarch64, __this_cpu_inc() is neither IRQ-safe nor atomic, so
when percpu_up_read() is invoked under IRQ-context (e.g. aio completion),
and it interrupts the process on the same CPU which is invoking
percpu_down_read(), the decreasement on read_count may lost and
the final value of read_count on the CPU will be unexpected
as shown below:

  CPU 0          CPU 0

  io_submit_one
  __sb_start_write
  percpu_down_read
  __this_cpu_inc
  // there is already an inflight IO, so
  // reading *raw_cpu_ptr(&pcp) returns 1
  // half complete, then being interrupted
  *raw_cpu_ptr(&pcp)) += 1

  		nvme_irq
  		nvme_complete_cqes
  		blk_mq_complete_request
  		nvme_pci_complete_rq
  		nvme_complete_rq
  		blk_mq_end_request
  		blk_update_request
  		bio_endio
  		dio_bio_end_aio
  		aio_complete_rw
  		__sb_end_write
  		percpu_up_read
  		*raw_cpu_ptr(&pcp)) -= 1
  		// *raw_cpu_ptr(&pcp) is 0

  // the decreasement is overwritten by the increasement
  *raw_cpu_ptr(&pcp)) += 1
  // the final value is 1 + 1 = 2 instead of 1

Fixing it by using the IRQ-safe helper this_cpu_inc|dec() for
operations on read_count.

Another plausible fix is to state that percpu-rwsem can NOT be
used under IRQ context and convert all users which may
use it under IRQ context.

*groan*...

So yeah, fs/super totally abuses percpu_rwsem, and yes, using it from
IRQ context is totally out of spec. That said, we've (grudgingly)
accomodated them before.

This seems to be a fairly long standing issue, and certainly not unique
to ARM64 either (Power, and anyone else using asm-gemeric/percpu.h,
should be similarly affected I think). The issue seems to stem from
Oleg's original rewrite:

  a1fd3e24d8a4 ("percpu_rw_semaphore: reimplement to not block the readers unnecessarily")

and is certainly an understandable mistake.

I'm torn on what to do, using this_cpu over __this_cpu is going to
adversely affect code-gen (and possibly performance) for all the
percpu-rwsem users that are not quite so 'creative'.

Yes, I didn't expect percpu_up_ can be called from IRQ :/

Not really... I think it was 70fe2f48152e ("aio: fix freeze protection of aio writes").
And iiuc io_uring does the same.

Yes, but what else can we do?

Yeah, me neither. That's well out of spec for a blocking primitive in
general.

Ah, that came later? Fair enough, I'll change the Fixes line.

Indeed, I just went through a bunch of the file_end_write() callers.

Well, I just talked about it with Will, there's a bunch of things we
could do, but they're all quite ugly.

My leading alternative was adding: percpu_down_read_irqsafe() /
percpu_up_read_irqsafe(), which use local_irq_save() instead of
preempt_disable().

But blergh.. Will also argued that by going with this patch, we'll get
an affected workload when someone reports a performance regression,
which I suppose is a bonus.

Anyway, I'll rewrite the Changelog and stuff it in locking/urgent.

Subject: locking/percpu-rwsem: Use this_cpu_{inc,dec}() for read_count
From: Hou Tao <houtao1@huawei.com>
Date: Tue, 15 Sep 2020 22:07:50 +0800

From: Hou Tao <houtao1@huawei.com>

The __this_cpu*() accessors are (in general) IRQ-unsafe which, given
that percpu-rwsem is a blocking primitive, should be just fine.

However, file_end_write() is used from IRQ context and will cause
load-store issues.

Fixing it by using the IRQ-safe this_cpu_*() for operations on
read_count. This will generate more expensive code on a number of
platforms, which might cause a performance regression for some of the
other percpu-rwsem users.

If any such is reported, we can consider alternative solutions.

That's not entirely accurate, on x86 for example the per-cpu ops are not
atomic, but they are not susceptible to this problem due to them being a
single instruction from the point of interrupts -- either they wholly
happen or they don't.

So I'd reformulate it like: "... on architectures where the per-cpu
accessors are not natively irq-safe" ?

Hey, the implication is still correct though ;)

I have simply test the performance impact on both x86 and aarch64.

There is no degradation under x86 (2 sockets, 18 core per sockets, 2 threads per core)

v5.8.9
no writer, reader cn                               | 18        | 36        | 72
the rate of down_read/up_read per second           | 231423957 | 230737381 | 109943028
the rate of down_read/up_read per second (patched) | 232864799 | 233555210 | 109768011

However the performance degradation is huge under aarch64 (4 sockets, 24 core per sockets): nearly 60% lost.

v4.19.111
no writer, reader cn                               | 24        | 48        | 72        | 96
the rate of down_read/up_read per second           | 166129572 | 166064100 | 165963448 | 165203565
the rate of down_read/up_read per second (patched) |  63863506 |  63842132 |  63757267 |  63514920

I will test the aarch64 host by using v5.8 tomorrow.

Tao

Yeah, x86 is magical here, it's the same single instruction for both ;-)
But it is, afaik, unique in this position, no other arch can pull that
off.

Thanks. We did improve the preempt_count() munging a bit since 4.19 (I
think), so maybe 5.8 will be a bit better. Please report back!

I believe perhaps Peter Z's suggestion of an additional
percpu_down_read_irqsafe() API and let only those in IRQ users pay the 
penalty.

This means that __sb_start/end_write() and probably more users in fs/super.c
will have to use this API, not good.

IIUC, file_end_write() was never IRQ safe (at least if !CONFIG_SMP), even
before 8129ed2964 ("change sb_writers to use percpu_rw_semaphore"), but this
doesn't matter...

Perhaps we can change aio.c, io_uring.c and fs/overlayfs/file.c to avoid
file_end_write() in IRQ context, but I am not sure it's worth the trouble.

If we change bio_endio to invoke the ->bi_end_io callbacks in softirq
context instead of hardirq context, we can change the pagecache to take
BH-safe locks instead of IRQ-safe locks.  I believe the only reason the
lock needs to be IRQ-safe is for the benefit of paths like:

mpage_end_io
page_endio
end_page_writeback
test_clear_page_writeback

Admittedly, I haven't audited all the places that call end_page_writeback;
there might be others called from non-BIO contexts (network filesystems?).
That was the point where I gave up my investigation of why we use an
IRQ-safe spinlock when basically all page cache operations are done
from user context.

SoftIRQ context has exactly the same problem vs __this_cpu*().

Not sure I understand...

How can this help? irq_exit() can invoke_softirq() -> __do_softirq() ?

 From my totally subjective experience on the filesystem side (user of 
bio_endio) all HW block drivers I used including Nvme isci, sata... etc. 
end up calling bio_endio in softirq. The big exception to that is the 
vdX drivers under KVM. Which is very Ironic to me.
I wish we could make all drivers be uniform in this regard.

But maybe I'm just speaking crap. Its only from my limited debuging 
expirience.

NVMe normally calls it from hardirq or IPI context.  The only time it
would use softirq context is if you have a single I/O queue, which is
very unusual.

Well, that would be IMO rather difficult. We need to do file_end_write()
after the IO has completed so if we don't want to do it in IRQ context,
we'd have to queue a work to a workqueue or something like that. And that's
going to be expensive compared to pure per-cpu inc/dec...

If people really wanted to avoid irq-safe inc/dec for archs where it is
more expensive, one idea I had was that we could add 'read_count_in_irq' to
percpu_rw_semaphore. So callers in normal context would use read_count and
callers in irq context would use read_count_in_irq. And the writer side
would sum over both but we don't care about performance of that one much.

That's not a bad idea... something like so I suppose.

I suppose an alternative way of writing that would be something like:

	union {
		u64 sum;
		struct {
			u32 a, b;
		};
	} var;

	var.sum = per_cpu_sum(*(u64 *)sem->read_count);

	if (var.a + var.b)
		return false;

which is more verbose, but perhaps easier to read.

Or we can re-introduce "atomic_t slow_read_ctr".

	percpu_up_read_irqsafe(sem)
	{
		preempt_disable();
		atomic_dec_release(&sem->slow_read_ctr);
		if (!rcu_sync_is_idle(&sem->rss))
			rcuwait_wake_up(&sem->writer);
		preempt_enable();
	}

	readers_active_check(sem)
	{
		unsigned int sum = per_cpu_sum(*sem->read_count) +
			(unsigned int)atomic_read(&sem->slow_read_ctr);
		if (sum)
			return false;
		...
	}

Of course, this assumes that atomic_t->counter underflows "correctly", just
like "unsigned int".

But again, do we really want this?

We're documented that we do. Lots of code relies on that.

See Documentation/atomic_t.txt TYPES

I like the two counters better, avoids atomics entirely, some archs
hare horridly expensive atomics (*cough* power *cough*).

I just tried to be clever and use a single u64 load (where possible)
instead of two 32bit loads and got the sum vs split order wrong.

I meant... do we really want to introduce percpu_up_read_irqsafe() ?

Perhaps we can live with the fix from Hou? At least until we find a
"real" performance regression.

I can say that for users of percpu rwsem in filesystems the cost of atomic
inc/dec is unlikely to matter. The lock hold times there are long enough
that it would be just lost in the noise.

For other stuff using them like get_online_cpus() or get_online_mems() I'm

I'm not sure that is correct. We do an inc/dec pair per AIO, so if
we are running millions of IOPS through the AIO subsystem, then the
cost of doing millions of extra atomic ops every second is going to
be noticable...

Hi Will & Ard,

+to Ard Biesheuvel <ardb@kernel.org> for the "regression" caused by 91fc957c9b1d6

Sorry for the long delay.

The line above is actually the performance of v5.9-rc5 under the same aarch64 host without any patch, but
the performance after applied the patch under v4.9.111 is still bad (see below, ~50% lost).

The following is the newest performance data:

It seems that enabling LSE atomic has a negative impact on performance under this test scenario.

And it is astonished to me that for my test scenario the performance of v5.9-rc6 is just one half of v4.19.
The bisect finds the culprit is 91fc957c9b1d6 ("arm64/bpf: don't allocate BPF JIT programs in module memory").
If reverting the patch brute-forcibly under 5.9-rc6 [2], the performance will be the same with
v4.19.111 (169664061 vs 166129572). I have had the simplified test module [3] and .config attached [4],
so could you please help to check what the problem is ?

Tao

Unless the benchmark could be affected by the fact that BPF programs
are now loaded out of direct branching range of the core kernel, I
don't see how that patch could affect performance in this way.

What you could do is revert the patch partially - drop the new alloc
and free routines, but retain the new placement of the module and
kernel areas, which all got shifted around as a result. That would at
least narrow it down, although it looks very unlikely to me that this
change itself is the root cause of the regression.
