I will straightaway note that I have been fiddling with my board's 
device tree, specifically (breaking!) the NUMA distance map, like this:

distance-matrix = <0 0 10>,
                    <0 1 15>,
                    <0 2 20>,
                    <0 3 25>,
                    <1 0 15>,
                    <1 1 10>,
                    <1 2 25>,
                    <1 3 30>,
                    <2 0 20>,
                    <2 1 25>,
                    <2 2 10>,
                    <2 3 15>,
                    <3 0 10>,* should be same as 0->3 and > 10
                    <3 1 10>,* should be same as 1->3 and > 10
                    <3 2 15>,
                    <3 3 15>;* should be 10

However I don't think that this should crash the kernel. I'd say 
of_numa_parse_distance_map_v1() should robustly handle broken maps, 
probably by erroring and causing NUMA to be disabled.

However I am interested to know if the scheduler crash is a real problem.

The kernel is 4.19. Full log is below.

Thanks,
John

JFYI, I bisected this issue to the following patch:

commit 58d5af59d55b4e9f3015207afa6a6648e9b005b1
Author: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com>
Date:   Thu Sep 7 02:20:05 2017 -0500

     sched/topology: Introduce NUMA identity node sched domain

     On AMD Family17h-based (EPYC) system, a logical NUMA node can contain
     upto 8 cores (16 threads) with the following topology.

which either exposes or causes this issue.

If build with CONFIG_SCHED_DEBUG=y and boot with "sched_debug" I think
sched_init_numa() should yell at you for the above 'mistake'.

Right, I have since turned on debug and it was complaining - I'll 
provide a log.

JFYI, https://lkml.org/lkml/2018/10/26/527

So it seems to be that setting the distance between separate nodes to 
LOCAL_DISTANCE causes the problem. x86 NUMA code - like arm64 - allows 
this. However ACPI SLIT validation rejects this, unlike OF distance map 
parsing.

Thanks,

Yeah, that's an 'obviously' broken topology too.

Clearly you're far more creative than the ACPI BIOS people have been so
far.

The actual crash callchain seems to be
destroy_sched_domain()->free_sched_groups():

static void free_sched_groups(struct sched_group *sg, int free_sgc)
{
...
     do {
         tmp = sg->next;

         if (free_sgc && atomic_dec_and_test(&sg->sgc->ref))***
             kfree(sg->sgc);

...
}

*** crash occurs when free_sgc is non-zero and sg->sgc is NULL

And, as I mentioned earlier, I bisected this problem to 58d5af59d55b.

AFAICT, this conforms to ACPI spec SLIT rules, and the kernel SLIT 
validation allows this also. So maybe we should shout louder here or 
even mark the SLIT as invalid if totally broken.

Yeah, turns out to be random memory corruption; I've had the crash in a
number of weird places; also GCC version dependent.

KASAN is awesome and pinpointed the problem though.

You mean:

right? and yes indeed! The below fixes my reproducer:

Good find.

I plan to fix up OF map parsing to reject invalid distance maps.

However is this distance map so broken for the scheduler that it's 
better to reject this "valid" distance map also? If not, it may be nice 
for the user to know about it without having to enable scheduler debugging.

Thanks,

Right. Part of the problem is that I only have a few necessary
conditions (symmetry, trace-identity, node0-complete-distance) for the
distance table, but together they are not sufficient to determine if a
topology is 'good'.

(also, strictly speaking, non-symmetric topologies are possible -- think
uni-directional mesh links -- we've just not ever seen and validated
those)

That said; I can certainly make this code give up and warn harder on
those conditions.

How is something like the below?

That sounds reasonable, but I think that you would know better on the 
policy of whether it's better to give up when conditions are not met.

Regardless, a louder warn sounds good.

Ahhhh, unfortuately this change in isolation is not fixing the crash for

The KASAN bug report is essentially the same with and without this change.

I did not try the full patch, and I guess the problem would go away 
after the full patch is applied, but you may want to know the issue still..

Thanks,
John

Hurm.. sadness, means my reproduces doesn't reproduce quite enough :/
I'll see if I can somehow get something better going.

Quick update: As expected, v4.20-rc1 has the same issue.

I did notice that if I set the .flags and .sd_flags members for the NUMA 
identity sched domain topology level - as done for other domains:

--- a/kernel/sched/topology.c
+++ b/kernel/sched/topology.c
@@ -1455,6 +1455,8 @@ void sched_init_numa(void)

                 SD_INIT_NAME(NODE)
         };


... then no crash. I doubt that this is right ... but at least a fuller 
log to analyse (which may be useless, considering the previous point):
