Not just the system level tcp memory limit but we have actually seen in
production unneeded and unexpected memcg OOMs and the commit 4890b686f408
fixes those OOMs as well.

IMO this is not the right place to fix memcg performance overhead,
specifically because it will re-introduce the memcg OOMs issue. Please
fix the memcg overhead in the memcg code.

Please share the detail profile of the memcg code. I can help in
brainstorming and reviewing the fix.

Do you have regression data from any production workload? Please keep in
mind that many times we (MM subsystem) accepts the regressions of
microbenchmarks over complicated optimizations. So, if there is a real
production regression, please be very explicit about it.

Though memcached is actually used by people in production. So this isn't an unrealistic scenario.

Yes, memcached is used in production but I am not sure anyone runs 8
pairs of server and client on the same machine for production
workload. Anyways, we can discuss, if needed, about the practicality
of the benchmark after we have some impactful memcg optimizations.

The test is run on platform with 224 CPUs (HT enabled). It's not a must to run
8 pairs, the memcg charge hot paths can be observed if we run only one pair
but with more CPUs. Leverage all CPU resources on TCP connection to stress
contentions.

If we run less server-client pairs (<= 3), and each pair is with 28 CPUs shared,
that means <=84 CPUs actually run, there is no obvious memcg charge overhead
observed. But when we run more than 112 CPUs (>= 4 pairs) to stress the system
with TCP memory allocation, memcg charge will be the bottleneck.

RE: [PATCH net-next 1/2] net: Keep sk->sk_forward_alloc as a proper size

[Zhang, Cathy]

Hi Shakeel, Eric and all,

How about adding memory pressure checking in sk_mem_uncharge()
to decide if keep part of memory or not, which can help avoid the issue
you fixed and the problem we find on the system with more CPUs.

The code draft is like this:

static inline void sk_mem_uncharge(struct sock *sk, int size)
{
        int reclaimable;
        int reclaim_threshold = SK_RECLAIM_THRESHOLD;

        if (!sk_has_account(sk))
                return;
        sk->sk_forward_alloc += size;

        if (mem_cgroup_sockets_enabled && sk->sk_memcg &&
            mem_cgroup_under_socket_pressure(sk->sk_memcg)) {
                sk_mem_reclaim(sk);
                return;
        }

        reclaimable = sk->sk_forward_alloc - sk_unused_reserved_mem(sk);

        if (reclaimable > reclaim_threshold) {
                reclaimable -= reclaim_threshold;
                __sk_mem_reclaim(sk, reclaimable);
        }
}

I've run a test with the new code, the result looks good, it does not introduce
latency, RPS is the same.

It will not work for sockets that are idle, after a burst.
If we restore per socket caches, we will need a shrinker.
Trust me, we do not want that kind of big hammer, crushing latencies.

Have you tried to increase batch sizes ?

Any kind of cache (even per-cpu) might need some adjustment when core
count or expected traffic is increasing.
This was somehow hinted in

I jus picked up 256 and 1024 for a try, but no help, the overhead still exists.

This makes no sense at all.

I suspect a plain bug in mm/memcontrol.c

I will let mm experts work on this.

Eric,

I added a pr_info in try_charge_memcg() to print nr_pages if
nr_pages >= MEMCG_CHARGE_BATCH, except it prints 64 during the initialization
of instances, there is no other output during the running. That means nr_pages is not
over 64, I guess that might be the reason why to increase MEMCG_CHARGE_BATCH
doesn't affect this case.

I am assuming you increased MEMCG_CHARGE_BATCH to 256 and 1024 but
that did not help. To me that just means there is a different
bottleneck in the memcg charging codepath. Can you please share the
perf profile? Please note that memcg charging does a lot of other
things as well like updating memcg stats and checking (and enforcing)
memory.high even if you have not set memory.high.

Thanks Shakeel! I will check more details on what you mentioned. We use
"sudo perf top -p $(docker inspect -f '{{.State.Pid}}' memcached_2)" to monitor
one of those instances, and also use "sudo perf top" to check the overhead from
system wide.

Here is the annotate output of perf top for the three memcg hot paths:

This is rephrasing the info you gave earlier ?

  16.77%  [kernel]            [k] page_counter_try_charge
    16.56%  [kernel]            [k] page_counter_cancel
    15.65%  [kernel]            [k] try_charge_memcg

What matters here is a call graph.

perf record -a -g sleep 5 # While the test is running
perf report --no-children --stdio

What precise kernel are you using btw ?

Yep, I just want to show some details.

Thanks for explanation. I re-collect it.

Here is the output with the command you paste, it's from system wide,
I only show pieces of memcached records, and it seems to be a

I am suspecting we are doing a lot of charging for a specific memcg on
one CPU (or a set of CPUs) and a lot of uncharging on the different
CPU (or a different set of CPUs) and thus both of these code paths are
hitting the slow path a lot.

Eric, I remember we have an optimization in the networking stack that
tries to free the memory on the same CPU where the allocation
happened. Is that optimization enabled for this code path? Or maybe we
should do something similar in memcg code (with the assumption that my
suspicion is correct).

The suspect part is really:

Shakeel, networking has a per-cpu cache, of +/- 1MB.

Even with asymmetric alloc/free, this would mean that a 100Gbit NIC
would require something like 25,000
operations on the shared cache line per second.

Hardly an issue I think.

memcg does not seem to have an equivalent strategy ?

memcg has +256KiB per-cpu cache (note the absence of '-'). However it
seems like Cathy already tested with 4MiB (1024 page batch) which is
comparable to networking per-cpu cache (i.e. 2MiB window) and still
see the issue. Additionally this is a single machine test (no NIC),
so, I am kind of contemplating between (1) this is not real world
workload and thus ignore or (2) implement asymmetric charge/uncharge
strategy for memcg.

I do want to understand for above which specific condition in
__refill_stock is causing to drain stock in the charge code path. Can
you please re-run and profile your test with following code snippet (or
use any other mechanism which can answer the question)?

Thanks a lot. This tells us that one or both of following scenarios are
happening:

1. In the softirq recv path, the kernel is processing packets from
multiple memcgs.

2. The process running on the CPU belongs to memcg which is different
from the memcgs whose packets are being received on that CPU.

BTW have you seen this performance issue when you run the client and
server on different machines? I am wondering if RFS would be good enough
for such scenario and we only need to worry about the same machine case.

Thanks for sharing the points, Shakeel! Is there any trace records you want to
collect?

The same test scenario is tried between two machines which are on the same
network but with network topology, both of the two machines are with 1Gbit NIC.
There is no hot paths observed, but it might because that the systems are
not so busy, for memtier shows the average transfer speed is down to a few
tenth of original on the same machine.

Hi Shakeel,

Try the following patch, the data of 'perf top' from system wide indicates that
the overhead of page_counter_cancel is dropped from 15.52% to 4.82%.

Without patch:
    15.52%  [kernel]            [k] page_counter_cancel
    12.30%  [kernel]            [k] page_counter_try_charge
    11.97%  [kernel]            [k] try_charge_memcg

With patch:
    10.63%  [kernel]            [k] page_counter_try_charge
     9.49%  [kernel]            [k] try_charge_memcg
     4.82%  [kernel]            [k] page_counter_cancel

The patch is applied on the latest net-next/main:
befcc1fce564 ("sfc: fix use-after-free in efx_tc_flower_record_encap_match()")

Thanks a lot Cathy.

Feng/Yin/Oliver, can you please test the patch at [1] with other
workloads used by the test robot? Basically I wanted to know if it has
any positive or negative impact on other perf benchmarks.

Thanks in advance.

is it possible for you to resend patch with Signed-off-by?
without it, test robot will regard the patch as informal, then it cannot feed
into auto test process.
and could you tell us the base of this patch? it will help us apply it
correctly.

on the other hand, due to resource restraint, we normally cannot support
this type of on-demand test upon a single patch, patch set, or a branch.
instead, we try to merge them into so-called hourly-kernels, then distribute
tests and auto-bisects to various platforms.
after we applying your patch and merging it to hourly-kernels sccussfully,
if it really causes some performance changes, the test robot could spot out
this patch as 'fbc' and we will send report to you. this could happen within
several weeks after applying.
but due to the complexity of whole process (also limited resourse, such like
we cannot run all tests on all platforms), we cannot guanrantee capture all
possible performance impacts of this patch. and it's hard for us to provide
a big picture like what's the general performance impact of this patch.
this maybe is not exactly what you want. is it ok for you?

Yes, that is fine and thanks for the help. The patch is below:


From 93b3b4c5f356a5090551519522cfd5740ae7e774 Mon Sep 17 00:00:00 2001

Subject: [PATCH] memcg: skip stock refill in irq context

The linux kernel processes incoming packets in softirq on a given CPU
and those packets may belong to different jobs. This is very normal on
large systems running multiple workloads. With memcg enabled, network
memory for such packets is charged to the corresponding memcgs of the
jobs.

Memcg charging can be a costly operation and the memcg code implements
a per-cpu memcg charge caching optimization to reduce the cost of
charging. More specifically, the kernel charges the given memcg for more
memory than requested and keep the remaining charge in a local per-cpu
cache. The insight behind this heuristic is that there will be more
charge requests for that memcg in near future. This optimization works
well when a specific job runs on a CPU for long time and majority of the
charging requests happen in process context. However the kernel's
incoming packet processing does not work well with this optimization.

Recently Cathy Zhang has shown [1] that memcg charge flushing within the
memcg charge path can become a performance bottleneck for the memcg
charging of network traffic.

Perf profile:

8.98%  mc-worker        [kernel.vmlinux]          [k] page_counter_cancel
    |
     --8.97%--page_counter_cancel
	       |
		--8.97%--page_counter_uncharge
			  drain_stock
			  __refill_stock
			  refill_stock
			  |
			   --8.91%--try_charge_memcg
				     mem_cgroup_charge_skmem
				     |
				      --8.91%--__sk_mem_raise_allocated
						__sk_mem_schedule
						|
						|--5.41%--tcp_try_rmem_schedule
						|          tcp_data_queue
						|          tcp_rcv_established
						|          tcp_v4_do_rcv
						|          tcp_v4_rcv

The simplest way to solve this issue is to not refill the memcg charge
stock in the irq context. Since networking is the main source of memcg
charging in the irq context, other users will not be impacted. In
addition, this will preseve the memcg charge cache of the application
running on that CPU.

There are also potential side effects. What if all the packets belong to
the same application and memcg? More specifically, users can use Receive
Flow Steering (RFS) to make sure the kernel process the packets of the
application on the CPU where the application is running. This change may
cause the kernel to do slowpath memcg charging more often in irq
context.

Could we have per-memcg per-cpu caches, instead of one set of per-cpu caches
needing to be drained evertime a cpu deals with 'another memcg' ?

The hierarchical nature of memcg makes that a bit complicated. We have
something similar for memcg stats which is rstat infra where the stats
are saved per-memcg per-cpu and get accumulated hierarchically every 2
seconds. This works fine for stats but for limits there would be a
need for some additional restrictions.

Also sometime ago Andrew asked me to explore replacing the atomic
counter in page_counter with percpu_counter. Intuition is that most of
the time the usage is not hitting the limit, so we can use
__percpu_counter_compare for enforcement.

Let me spend some time to explore per-memcg per-cpu cache or if
percpu_counter would be better.

For now, this patch is more like an RFC.

Greetings Shakeel,

Hope this message finds you well. I want to inquiry about the current status of
the fixing. Have you completed the evaluation and started working on the final
solution?

Thanks! we've already fetched the patch in our hourly kernels which under
performance testing now (in fact, as well as func tests)

the testing and bisection could last several days to several weeks, and if
bisected to this commit for any changes such like performance regression or
improvement, we will send report to you.

however, again, if you didn't see any report, it just mean our test robot
cannot sucessfully spot out this commit as the reason for  any performance/func
changes.

we applied below patch upon v6.4-rc2, so far, we didn't spot out performance
impacts of it to other tests.

but we found -7.6% regression of netperf.Throughput_Mbps

testcase: netperf
test machine: 128 threads 4 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory
parameters:

	ip: ipv4
	runtime: 300s
	nr_threads: 50%
	cluster: cs-localhost
	send_size: 10K
	test: TCP_SENDFILE
	cpufreq_governor: performance


To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.

> Subject: [PATCH] memcg: skip stock refill in irq context
> 
> The linux kernel processes incoming packets in softirq on a given CPU
> and those packets may belong to different jobs. This is very normal on
> large systems running multiple workloads. With memcg enabled, network
> memory for such packets is charged to the corresponding memcgs of the
> jobs.
> 
> Memcg charging can be a costly operation and the memcg code implements
> a per-cpu memcg charge caching optimization to reduce the cost of
> charging. More specifically, the kernel charges the given memcg for more
> memory than requested and keep the remaining charge in a local per-cpu
> cache. The insight behind this heuristic is that there will be more
> charge requests for that memcg in near future. This optimization works
> well when a specific job runs on a CPU for long time and majority of the
> charging requests happen in process context. However the kernel's
> incoming packet processing does not work well with this optimization.
> 
> Recently Cathy Zhang has shown [1] that memcg charge flushing within the
> memcg charge path can become a performance bottleneck for the memcg
> charging of network traffic.

> The simplest way to solve this issue is to not refill the memcg charge
> stock in the irq context. Since networking is the main source of memcg
> charging in the irq context, other users will not be impacted. In
> addition, this will preseve the memcg charge cache of the application
> running on that CPU.
> 
> There are also potential side effects. What if all the packets belong to
> the same application and memcg? More specifically, users can use Receive
> Flow Steering (RFS) to make sure the kernel process the packets of the
> application on the CPU where the application is running. This change may
> cause the kernel to do slowpath memcg charging more often in irq
> context.

What is the memcg hierarchy of this workload? Is each server and
client processes running in their own memcg? How many levels of
memcgs? Are you setting memory.max and memory.high to some value? Also
how are you limiting the processes to CPUs? cpusets?

Here is the full command to start memcached instance:

docker run -d --name ${memcached_name} --privileged --memory 1G --network bridge \
-p ${port_i}:${port_i} ${cpu_pinning_s[set]} memcached memcached -p ${port_i} \
-t ${threads_i} -c 10240

We have a script to get CPU set from the same NUMA node, both CPU count and thread
count for each instance are equal to Num(system online CPUs) / Num(memcached instances).
That is, if we run 8 memcached instances, 224 / 8 = 28, so each instance will get 28 CPUs and
28 threads assigned.

Here is the full command to start memtier instance:
docker run --rm --network bridge ${cpu_pinning_s[set]} --memory 1G \
redislabs/memtier_benchmark memtier_benchmark --server=${memcached_id} --port=${port_i} \
--protocol=memcache_text --test-time=20 --threads=${threads_i} -c 1 --pipeline=16 --ratio=1:100 \
--run-count=5 --hide-histogram

Each instance has the same CPU set as the server it connects to, and it has the same threads
count.

That is all for server and client settings.
