[PATCH net-next 1/3] net: allow > 0 order atomic page alloc in skb_page_frag_refill

[Michael Dalton]

skb_page_frag_refill currently permits only order-0 page allocs
unless GFP_WAIT is used. Change skb_page_frag_refill to attempt
higher-order page allocations whether or not GFP_WAIT is used. If
memory cannot be allocated, the allocator will fall back to
successively smaller page allocs (down to order-0 page allocs).

This change brings skb_page_frag_refill in line with the existing
page allocation strategy employed by netdev_alloc_frag, which attempts
higher-order page allocations whether or not GFP_WAIT is set, falling
back to successively lower-order page allocations on failure. Part
of migration of virtio-net to per-receive queue page frag allocators.

[PATCH net-next 2/3] virtio-net: use per-receive queue page frag alloc for mergeable bufs

[Michael Dalton]

The virtio-net driver currently uses netdev_alloc_frag() for GFP_ATOMIC
mergeable rx buffer allocations. This commit migrates virtio-net to use
per-receive queue page frags for GFP_ATOMIC allocation. This change unifies
mergeable rx buffer memory allocation, which now will use skb_refill_frag()
for both atomic and GFP-WAIT buffer allocations.

To address fragmentation concerns, if after buffer allocation there
is too little space left in the page frag to allocate a subsequent
buffer, the remaining space is added to the current allocated buffer
so that the remaining space can be used to store packet data.

Any reason to use two different page_frag consider only

I wonder whether we can use get_a_page() and give_pages() to recycle the
pages like before which may help the performance. We can also do some
optimizations for this in vhost.

One is used under process context, where preemption and GFP_KERNEL are
allowed.

One is used from softirq context and GFP_ATOMIC. You cant share a common
page_frag.

Yes but it is always used with napi disabled.

This one is used only under napi.

So there isn't a conflict with respect to locking.

Is it problematic to use same page_frag with both GFP_ATOMIC and with
GFP_KERNEL? If yes why?

I believe it is safe to use the same page_frag and I will send out a
followup patchset using just the per-receive page_frags. For future
consideration, Eric noted that disabling NAPI before GFP_KERNEL
allocs can potentially inhibit virtio-net network processing for some
time (e.g., during a blocking memory allocation or preemption).

Best,

Mike

Seems easier to use it straight away I think.

Interesting. But if we can't allocate a buffer how can we
do network processing?

If we can reproduce the problem, we can maybe move
allocation out of napi disabled section, but then
we'll need to add more locking.

How typical NIC drivers handle this case ?

Answer : nothing special should happen, we drop incoming traffic,
and make sure the driver recovers properly. (like not NULL deref or
crazy things like that)

Why virtio_net should be different ?

Basically yes, we could start dropping packets immediately
once GFP_ATOMIC allocations fail and repost the buffer to host,
and hope memory is available by the time we get the next interrupt.
But we wanted host to have visibility into the fact that
we are out of memory and packets are dropped, so we did not want to
repost.
If we don't repost how do we know memory is finally available?
We went for a timer based workqueue thing.
What do you suggest?

In normal networking land, when a host A sends frames to host B,
nothing prevents A to pause the traffic to B if B is dropping packets
under stress.

A physical NIC do not use a workqueue to refill its RX queue but uses
the following strategy :

0) Pre filling of RX ring buffer with N frames. This can use GFP_KERNEL
   allocations with all needed (sleep/retry/shout) logic...
1) IRQ is handled.
2) Can we allocate a new buffer (GFP_ATOMIC) ?
   If yes, we accept the frame,
      and post the new buffer for the 'next frame'
   If no, we drop the frame and recycle the memory for next round.

I guess you are saying we never need to signal host/device
that we are out of memory, it's enough that packets are dropped?
It seemed like a useful thing for hypervisor to know about on general
principles, even though I don't think kvm uses this info at this point.

Exactly, this is what I tried to describe in the part that
you have snipped out - but this means queue is always full.

Also, I wonder whether allocating before passing
frame to the stack might slow us down a tiny bit e.g. if an application
is polling this socket on another CPU.

Maybe a slightly better strategy is to do the above when queue depth
is running low. E.g. when queue is 3/4 empty, try
allocating before giving frames to net core,
and recycle buffers on error.

Not sure how much of a win this is.

          and increment a suitably specific statistic so someone trying 
to diagnose performance/other problems can know we dropped the frame.

Yep, using napi_disable() in the refill process looks quite inefficient
to me, it not buggy.

napi_disable() is a big hammer, while whole idea of having a process to
block on GFP_KERNEL allocations is to allow some asynchronous behavior.

I have hard time to convince myself virtio_net is safe anyway with this
work queue thing.

virtnet_open() seems racy for example :

        for (i = 0; i < vi->max_queue_pairs; i++) {
                if (i < vi->curr_queue_pairs)
                        /* Make sure we have some buffers: if oom use wq. */
                        if (!try_fill_recv(&vi->rq[i], GFP_KERNEL))
                                schedule_delayed_work(&vi->refill, 0);
                virtnet_napi_enable(&vi->rq[i]);


What if the workqueue is scheduled _before_ the call to virtnet_napi_enable(&vi->rq[i]) ?

refill_work() will happily conflict with another cpu, two cpus could 
call try_fill_recv() at the same time, or worse napi_enable() would crash.

I do not have time to make a full check, but I guess there are
other races like this one.

Then napi_disable() in refill_work() will busy wait until napi is
enabled by virtnet_napi_enable() which looks safe. Looks like the real
issue is in virtnet_restore() who calls try_fill_recv() in neither napi
context nor napi disabled context.

I think you don't really get the race.

The issue is the following :

CPU0                                                        CPU1

schedule_delayed_work()
                                          napi_disable(&rq->napi);
                                          try_fill_recv(rq, GFP_KERNEL);

virtnet_napi_enable(&vi->rq[i]);
...
try_fill_recv(rq, GFP_ATOMIC);

                                         napi_enable();// crash on :
                                           BUG_ON(!test_bit(NAPI_STATE_SCHED, &n->state));

If I didn't miss anything. In this case, for a specific rq,
napi_disable() won't return immediately since NAPI_STATE_SCHED bit was
still set. It will busy wait until NAPI_STATE_SCHED bit was clear by
virtnet_napi_enable(), and then reset the bit. So try_fill_recv() should
be called after its napi was enabled by virtnet_napi_enable() in CPU0.

So the following order were guaranteed:
- try_fill_recv(rq, GFP_ATOMIC) in CPU0
- virtnet_napi_enable(&vi->rq[i]) in CPU0
- napi_disable(&rq->napi) returned in CPU1
- try_fill_recv(rq) in CPU1

OK so just to clarify, this is intended as a cleanup

I note that netdev_alloc_frag sets __GFP_COLD which kind of
makes sense.

I also note that netdev_alloc_frag uses some tricks to
reduce the amount of cache lines dirtied - need to look
at whether they actually apply here.

[PATCH net-next 3/3] net: auto-tune mergeable rx buffer size for improved performance

[Michael Dalton]

Commit 2613af0ed18a ("virtio_net: migrate mergeable rx buffers to page frag
allocators") changed the mergeable receive buffer size from PAGE_SIZE to
MTU-size, introducing a single-stream regression for benchmarks with large
average packet size. There is no single optimal buffer size for all
workloads.  For workloads with packet size <= MTU bytes, MTU + virtio-net
header-sized buffers are preferred as larger buffers reduce the TCP window
due to SKB truesize. However, single-stream workloads with large average
packet sizes have higher throughput if larger (e.g., PAGE_SIZE) buffers
are used.

This commit auto-tunes the mergeable receiver buffer packet size by
choosing the packet buffer size based on an EWMA of the recent packet
sizes for the receive queue. Packet buffer sizes range from MTU_SIZE +
virtio-net header len to PAGE_SIZE. This improves throughput for
large packet workloads, as any workload with average packet size >=
PAGE_SIZE will use PAGE_SIZE buffers.

These optimizations interact positively with recent commit
ba275241030c ("virtio-net: coalesce rx frags when possible during rx"),
which coalesces adjacent RX SKB fragments in virtio_net. The coalescing
optimizations benefit buffers of any size.

Benchmarks taken from an average of 5 netperf 30-second TCP_STREAM runs
between two QEMU VMs on a single physical machine. Each VM has two VCPUs
with all offloads & vhost enabled. All VMs and vhost threads run in a
single 4 CPU cgroup cpuset, using cgroups to ensure that other processes
in the system will not be scheduled on the benchmark CPUs. Trunk includes
SKB rx frag coalescing.

net-next w/ virtio_net before 2613af0ed18a (PAGE_SIZE bufs): 14642.85Gb/s
net-next (MTU-size bufs):  13170.01Gb/s

OK so a high level benchmark shows it's worth it,
but how well does the logic work?
I think we should make the buffer size accessible in sysfs
or debugfs, and look at it, otherwise we don't really know.

I don't get the real motivation for this.

We have skbs A,B,C sharing a page, with chunk D being unused.
This randomly charges chunk D to an skb that ended up last
in the page.
Correct?
Why does this make sense?

If the explanation for the above is that we don't care where D is
charged, let's not charge it to any skbs.

Why head_skb only? Why not full buffer size that comes from host?
This is simply len.

Also I guess this 1% difference is in the noise, right?
Could you share data about host CPU utilization during
these runs please?

Hi Michael Dalton,

In Autotest framework, we compare performance results by T-test [1], and generate
an abundant/meaningful HTML files. It's helpful to check if performance regression
exists significantly.

If you have interest, we also use this in your netperf testing.

Attached analysis results of netperf tests.

Thanks, Amos

Nice. Specifically, this checks Throughput divided by CPU utilization
which is important I think.
Sometimes host scheduler gives us much more CPU and throughput
goes up, but if that's what happens, it won't scale with other work running on same host.

The patch looks good to me and test this patch with mlx4, it help to
increase the rx performance from about 22Gb/s to about 26 Gb/s.

Exporting the size sounds good to me, it is definitely an
important metric and would give more visibility to the admin.

Do you have a preference for implementation strategy? I was
thinking just add a DEVICE_ATTR to create a read-only sysfs file,
'mergeable_rx_buffer_size', and return a space-separated list of the
current buffer size (computed from the average packet size) for each
receive queue. -EINVAL or a similar error could be returned if the
netdev was not configured for mergeable rx buffers.

The intent of this code is to adjust the SKB true size for
the packet. We should completely use each packet buffer except
for the last buffer. For all buffers except the last buffer, it
should be the case that 'len' (bytes received) = buffer size. For
the last buffer, this code adjusts the truesize by comparing the
approximated buffer size with the bytes received into the buffer,
and adding the difference to the SKB truesize if the buffer size
is greater than the number of bytes received.

We approximate the buffer size by using the last packet buffer size
from that same page, which as you have correctly noted may be a buffer
that belongs to a different packet on the same virtio-net device. This
buffer size should be very close to the actual buffer size because our
EWMA estimator uses a high weight (so the packet buffer size changes very
slowly) and there are only a handful packets on a page (even order-3).

> Why head_skb only? Why not full buffer size that comes from host?

Sorry, I believe this code fragment should be clearer. Basically, we
have a corner case in that for packets with size <= GOOD_COPY_LEN, there
are no frags because page_to_skb() already unref'd the page and the entire
packet contents are copied to skb->data. In this case, the SKB truesize
is already accurate and should not be updated (and it would be unsafe to
access page->private as page is already unref'd).

I'll look at the above code again and cleanup (please let me know if you
have a preference) and/or add a comment to clarify.

Best,

Mike

Not too important really. Maybe an attribute per queue? Might be
easier to parse and does not need tricky formatting.

I'll need to ponder it, don't understand it exactly.

But look like it does not take the 'hole' into account which may cause
under estimation of trusize.

We can make this more accurate by using extra data structure to track
the real buf size and using it as token.

Re: [PATCH net-next 3/3] net: auto-tune mergeable rx buffer size for improved performance

[Michael Dalton]

I'm working on a followup patchset to address current feedback. I think
it will be cleaner to do a debugfs implementation for per-receive queue
packet buffer size exporting, so I'm trying that out.

I agree -- we can do precise buffer total len tracking. Something like
struct mergeable_packet_buffer_ctx {
   void *buf;
   unsigned int total_len;
};

Each receive queue could have a pointer to an array of N buffer contexts,
where N is queue size (kzalloc'd in init_vqs or similar). That would
allow us to allocate all of our buffer context data at startup.

Would this be preferred to the current approach or is there another
approach you would prefer? All other things being equal, having precise
length tracking is advantageous, so I'm inclined to try this out and
see how it goes.

I think this is a big design point - for example, if we have an extra
buffer context structure, then per-receive queue frag allocators are not
required for auto-tuning and we can reduce the number of patches in
this patchset.

I'm happy to implement either way.  Thanks!

Best,

Mike

I think this is better since it was accurate and easier to be
implemented and understand.

Not required but better keep it. Consider we may have multiple
virtio-net cards, using per-receive queue frag may increase the
possibility of coalescing.

Maybe make total_len long so size is a power of 2.

Hmm this doubles VQ cache footprint.
In the past when I tried increasong cache footprint
this hurt performance measureable. It's just a suggestion though,
YMMV, if numbers are good we don't need to argue about this.

I'd be careful with adding even more stuff in
mergeable_packet_buffer_ctx for above reason.

I think it's a good idea, certainly the best we can do
short term.
Would like a couple of comments addressed before it's applied.

Longer term one approach to consider is to make device
look aheads in the VQ until it finds a large
enough buffer.

The original code seems try to avoid the high order allocation for
atomic allocation. This patch changes this, and looks like it will
introduce some extra cost when the memory is highly fragmented.

No noticeable extra cost that I could measure.

We use the same strategy in RX path nowadays.

I don't get how this is related to patch 3/3 exactly.
That one seems to clamp the allocations from ewma to at most
PAGE_SIZE, so how to we get higher-order allocations here?
Could you clarify please?

If your ewma stabilizes at 2050 bytes per frag, using order-0 page will
waste ~50% of memory.

There is still feedback and/or minor adjustments being asked for wrt.
this series.   These changes have been sitting for more than a week
which is a bit rediculous.

Please resubmit these changes once everything is resolved to
everyone's satisfaction, thanks.

Re: [PATCH net-next 1/3] net: allow > 0 order atomic page alloc in skb_page_frag_refill

[Debabrata Banerjee]

Currently because of how mm behaves (3.10.y) the code even before the
patch is a problem. I believe what may fix it is if instead of just
removing the conditional on __GFP_WAIT, the initial order > 0
allocation should be made GFP_ATOMIC, then fallback to the original
gfp mask for the order-0 allocations.

On systems that have highly fragmented main memory with pressure,
skb_page_frag_refill() causes problems. mm enters significant
compaction cycles on all cpu's which in itself is bad (add
considerable spinlock contention in isolate_migratepages_range() for
several seconds in kernel at 100% cpu), however even without this
happening basically we have large memory reclaimation when only
allocations from order-3 were necessary. For example, I might see half
the existing page cache on a system (2GB out of 8GB) reclaimed in a
burst, which effectively means the application has to wait even longer
after this compact/reclaim cycle for those pages to be read back from
disk. This is a significant reduction in useful memory from before
skb_page_frag_refill() existed, as one of our systems could run in
steady state will little free memory and 100% fragmentation. Now I see
10-30x more memory free (read: not utilized). Order > 0 allocations
were happening rarely before, now it happens consistently from this
function.

My suggestion above would avoid mm going through
__alloc_pages_direct_compact() and triggering the bad events above. It
will take me several days to try this experiment.

My suggestion is to use a recent kernel, and/or eventually backport the
mm fixes if any.

order-3 allocations should not reclaim 2GB out of 8GB.

There is a reason PAGE_ALLOC_COSTLY_ORDER exists and is 3

Sorry 2GB cache out of 8GB phys, ~1GB gets reclaimed. Regardless the
reclaimation of cache is minor compared to the compaction event that
precedes it, I haven't spotted something addressing that yet -
isolate_migratepages_range ()/compact_checklock_irqsave(). If even
more of memory was unmoveable, the compaction routines would be hit
even harder as reclaimation wouldn't do anything - mm would have to
get very very smart about unmoveable pages being freed and just fail
allocations/oom kill if nothing has changed without running through
compaction/reclaim fruitlessly.

I guess this is a bit of a tangent since what I'm saying proves the
patch from Michael doesn't make this behavior worse.

Yes this seems like it will make the situation better, but one send()
may still cause a direct_compact and direct_reclaim() cycle to happen,
followed immediately by another direct_compact() if direct_reclaim()
didn't free an order-3. Now have all cpu's doing a send(), you can
still get heavy spinlock contention in the routines described above.
The major change I see here is that allocations > order-0 used to be
rare, now it's on every send().

I can try your patch to see how much things improve.

There is another patch needed (looks like good stable fixes):

This reduces the really pathological compact/reclaim behavior but
doesn't fix it. Actually it still really quite bad because the whole
thing loops until it gets to order-0 so it's effectively trying the
allocation 4 times anyway. I typically see non-zero order allocations
very rarely without these two pieces of code. I hotpatched a running
system to get results from this quickly. Even setting the max order to
order-1 I still see bad behavior. If anything this behavior should be
conditional until this is ironed out.

This is in GFP_ATOMIC cases, I dont think it can ever start compaction.

It seems that you shoot the messenger : If memory is fragmented, then
one order-1 allocation is going to start compaction.

It can be a simple fork().

If your workload never fork(), then yes, you never needed compaction.

It doesn't really matter to say that which memory allocation triggered
compaction, which is a normal step in mm layer.

If you believe its badly done, you should ask to mm guys to fix/improve
it, not netdev...

We are not trying to optimize the kernel behavior for hosts in deep
memory pressure.

Using order-3 pages in TCP stack improves performance for 99% of the
hosts, there might be something wrong on your side ?

I think that's right I probably finally got it back to normal behavior
with order-0 allocations.

Sure but the rate of network packets in and out and subsequent
allocations would be more equivalent to a fork bomb than normal
forking. I understand mm should work more sanely in this scenario but
at the same time we see a bad regression with this code, I see we're
not alone.

We're leaving about half for the kernel so I wouldn't call it "deep".
Any server application that is using page cache and mlocked memory
will run into similar issues.

Having lots of memory mlocked is bad right now yes, but not
necessarily an uncommon scenario. We're handing mm an almost
intractable problem. I see compaction of mlocked pages has been
discussed a few times over there, but no patch has actually made it
in.
