I am seeing a boot regression on one of our Tegra boards with both
mainline and -next. Bisecting is pointing to this commit and reverting
this commit on top of mainline fixes the problem. Unfortunately, there
is not much of a backtrace but what I have captured is below. 

Please note that this is seen on a system that is using NFS to mount
the rootfs and the crash occurs right around the point the rootfs is
mounted.

Let me know if you have any thoughts.

Cheers

You don't have any more data ? Can you activate DMA-API debug and check 
if there is any more info outputted ?

Yes this did not help. I tried enabling the following but no more output
is seen.

CONFIG_DMA_API_DEBUG=y
CONFIG_DMA_API_DEBUG_SG=y

Have you tried using NFS on a board with this ethernet controller?

I'm having some issues setting up the NFS server in order to replicate 
so this may take some time.

Are you able to add some debug in stmmac_init_rx_buffers() to see what's 
the buffer address ?

If that's the case, we may wish to consider reverting this for now as it
is preventing our board from booting. Appears to revert cleanly on top
of mainline.

If you have a debug patch you would like me to apply and test with I
can. However, it is best you prepare the patch as maybe I will not dump
the appropriate addresses.

Thanks. Can you add attached patch and check if WARN is triggered ? And 
it would be good to know whether this is boot specific crash or just 
doesn't work at all, i.e. not using NFS to mount rootfs and instead 
manually configure interface and send/receive packets.

BTW, also add the attached one in this mail. The WARN will probably 
never get triggered without it.

Can you also print "buf->addr" after the WARN_ON ?

With this patch applied I did not see the WARN trigger.

I booted the board without using NFS and then started used dhclient to
bring up the network interface and it appears to be working fine. I can
even mount the NFS share fine. So it does appear to be particular to
using NFS to mount the rootfs.

I simply removed the /lib/modules directory from the NFS share and
verified that I still see the same issue. So it is not loading the
modules that is a problem.

Well, I meant that loading modules can be an issue but that's not the 
way to verify that.

You need to have all modules built-in so that it proves that no module 
will try to be loaded.

Anyway, this is probably not the cause as you wouldn't even be able to 
compile kernel if you need a symbol from a module with stmmac built-in. 
Kconfig would complain about that.

The other cause could be data corruption in the RX path. Are you able to 
send me packet dump by running wireshark either in the transmitter side 
(i.e. NFS server), or using some kind of switch ?

The log says  someone calls panic() right?
Can we trye and figure were that happens during the stmmac init phase?

The reason for the panic is hidden in this one line of the kernel logs:
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

The init process is killed by SIGSEGV (signal 11 = 0xb).

I would suggest you look for data corruption bugs in the RX path. If
the code is fetched from the NFS mount then a corrupt RX buffer can
trigger a crash in userspace.

Jon, I'm not familiar with ARM. Are the buffer addresses being allocated 
in a coherent region ? Can you try attached patch which adds full memory 
barrier before the sync ?

TBH I am not sure about the buffer addresses either. The attached patch
did not help. Same problem persists.

OK. I'm just guessing now at this stage but can you disable SMP ?

We have to narrow down if this is coherency issue but you said that 
booting without NFS and then mounting manually the share works ... So, 
can you share logs with same debug prints in this condition in order to 
compare ?

Jon, I have one ARM based board and I can't face your issue but I 
noticed that my buffer addresses are being mapped using SWIOTLB. Can you 
disable IOMMU support on your setup and let me know if the problem 
persists ?

I tried limiting the number of CPUs to one by setting 'maxcpus=0' on the
kernel command line. However, this did not help.

This appears to be a winner and by disabling the SMMU for the ethernet
controller and reverting commit 954a03be033c7cef80ddc232e7cbdb17df735663
this worked! So yes appears to be related to the SMMU being enabled. We
had to enable the SMMU for ethernet recently due to commit
954a03be033c7cef80ddc232e7cbdb17df735663.

Finally :)

However, from "git show 954a03be033c7cef80ddc232e7cbdb17df735663":

+         There are few reasons to allow unmatched stream bypass, and
+         even fewer good ones.  If saying YES here breaks your board
+         you should work on fixing your board.

So, how can we fix this ? Is your ethernet DT node marked as 
"dma-coherent;" ?

The first thing to try would be booting the failing setup with 
"iommu.passthrough=1" (or using CONFIG_IOMMU_DEFAULT_PASSTHROUGH) - if

translation; if not, then it's probably time to start looking at nasties

Do you know if the SMMU interrupts are working correctly? If not, it's 
possible that an incorrect address or mapping direction could lead to 
the DMA transaction just being silently terminated without any fault 
indication, which generally presents as inexplicable weirdness (I've 
certainly seen that on another platform with the mix of an unsupported

Just to confirm, has the original patch been tested with 
CONFIG_DMA_API_DEBUG to rule out any high-level mishaps?

Yes but both my setups don't have any IOMMU: One is x86 + SWIOTLB and 
another is just coherent regarding CPU.

Setting "iommu.passthrough=1" works for me. However, I am not sure where
to go from here, so any ideas you have would be great.

If I simply remove the iommu node for the ethernet controller, then I
see lots of ...

[    6.296121] arm-smmu 12000000.iommu: Unexpected global fault, this could be serious
[    6.296125] arm-smmu 12000000.iommu:         GFSR 0x00000002, GFSYNR0 0x00000000, GFSYNR1 0x00000014, GFSYNR2 0x00000000

So I assume that this is triggering the SMMU interrupt correctly.

Yes one of the first things we tried but did not bare any fruit.

OK, so that really implies it's something to do with the addresses. From 
a quick skim of the patch, I'm wondering if it's possible for buf->addr 
and buf->page->dma_addr to get out-of-sync at any point. The nature of 
the IOVA allocator makes it quite likely that a stale DMA address will 
have been reused for a new mapping, so putting the wrong address in a 
descriptor may well mean the DMA still ends up hitting a valid 
translation, but which is now pointing to a different page.

According to tegra186.dtsi it appears you're using the MMU-500 combined 
interrupt, so if global faults are being delivered then context faults 
*should* also, but I'd be inclined to try a quick hack of the relevant 
stmmac_desc_ops::set_addr callback to write some bogus unmapped address 
just to make sure arm_smmu_context_fault() then screams as expected, and 
we're not missing anything else.

I hacked the driver and forced the address to zero for a test and
in doing so I see ...

[   10.440072] arm-smmu 12000000.iommu: Unhandled context fault: fsr=0x402, iova=0x00000000, fsynr=0x1c0011, cbfrsynra=0x14, cb=0

So looks like the interrupts are working AFAICT.

OK, that's good, thanks for confirming. Unfortunately that now leaves us 
with the challenge of figuring out how things are managing to go wrong 
*without* ever faulting... :)

I wonder if we can provoke the failure on non-IOMMU platforms with 
"swiotlb=force" - I have a few boxes I could potentially test that on, 
but sadly forgot my plan to bring one with me this morning.

Robin.

Then definitely we are accessing outside of a valid IOMMU mapping due
to the page pool support changes.

Such a problem should be spotted with swiommu enabled with debugging.

Yes. On the netsec driver i did test with and without SMMU to make sure i am not
breaking anything.
Since we map the whole page on the API i think some offset on the driver causes
that. In any case i'll have another look on page_pool to make sure we are not
missing anything.

Ilias, can it be due to this:

stmmac_main.c:
	pp_params.order = DIV_ROUND_UP(priv->dma_buf_sz, PAGE_SIZE);

page_pool.c:
	dma = dma_map_page_attrs(pool->p.dev, page, 0,
				 (PAGE_SIZE << pool->p.order),
				 pool->p.dma_dir, DMA_ATTR_SKIP_CPU_SYNC);

"order", will be at least 1 and then mapping the page can cause overlap 
?

well the API is calling the map with the correct page, page offset (0) and size
right? I don't see any overlapping here. Aren't we mapping what we allocate?

Why do you need higher order pages? Jumbo frames? Can we do a quick test with
the order being 0?

Yes, it's for Jumbo frames that can be as large as 16k.

From Jon logs it can be seen that buffers are 8k but frames are 1500 max 
so it is using order = 1.

On my setup, if I do not use NFS to mount the rootfs, but then manually
mount the NFS share after booting, I do not see any problems reading or
writing to files on the share. So I am not sure if it is some sort of
race that is occurring when mounting the NFS share on boot. It is 100%
reproducible when using NFS for the root file-system.

I am using the Jetson TX2 devkit [0] to test this.

I don't understand how can there be corruption then unless the IP AXI 
parameters are misconfigured which can lead to sporadic undefined 
behavior.

These prints from your logs:
[   14.579392] Run /init as init process
/init: line 58: chmod: command not found
[ 10:22:46 ] L4T-INITRD Build DATE: Mon Jul 22 10:22:46 UTC 2019
[ 10:22:46 ] Root device found: nfs
[ 10:22:46 ] Ethernet interfaces: eth0
[ 10:22:46 ] IP Address: 10.21.140.41

Where are they coming from ? Do you have any extra init script ?

By default there is an initial ramdisk that is loaded first and then the
rootfs is mounted over NFS. However, even if I remove this ramdisk and
directly mount the rootfs via NFS without it the problem persists. So I
don't see any issue with the ramdisk and whats more is we have been
using this for a long long time. Nothing has changed here.

OK. Can you please test what Ilias mentioned ?

Basically you can hard-code the order to 0 in 
alloc_dma_rx_desc_resources():
- pp_params.order = DIV_ROUND_UP(priv->dma_buf_sz, PAGE_SIZE);
+ pp_params.order = 0;

Unless you use a MTU > PAGE_SIZE.

Yea tbh i didn't expect this to fix it, since i think the mappings are fine, but
it never hurts to verify.
@Jose: Can we add some debugging prints on the driver?
Ideally the pages the api allocates (on init), the page that the driver is
trying to use before the crash and the size of the packet (right from the device
descriptor). Maybe this will tell us where the erroneous access is

Thanks

TBH I have no idea. I can't say I fully understand your change or how it
is breaking things for us.

Currently, the Tegra DT binding does not have 'dma-coherent' set. I see
this is optional, but I am not sure how you determine whether or not
this should be set.

From my understanding it means that your device / IP DMA accesses are coherent regarding the CPU point of view. I think it will be the case if GMAC is not behind any kind of IOMMU in the HW arch.

I don't know about this SMMU but the source does have some special 
conditions when device is dma-coherent.

I understand what coherency is, I just don't know how you tell if this
implementation of the ethernet controller is coherent or not.

Do you have any detailed diagram of your HW ? Such as blocks / IPs

Yes, this can be found in the Tegra X2 Technical Reference Manual [0].
Unfortunately, you need to create an account to download it.

My understanding is that Tegra186 does not have DMA coherency, but 
Tegra194 does.

I was looking at this change in a bit closer detail and one thing that
stuck out to me was the above where the barrier had been moved from
after the stmmac_set_rx_owner() call to before. 

So I moved this back and I no longer saw the crash. However, then I
recalled I had the patch to enable the debug prints for the buffer

In other words, what works for me is moving the above barrier and adding
the debug print, which appears to suggest that there is some
timing/coherency issue here. Anyway, maybe this is clue to what is going
on?

Well, I wasn't expecting that :/

Per documentation of barriers I think we should set descriptor fields 
and then barrier and finally ownership to HW so that remaining fields 
are coherent before owner is set.

Anyway, can you also add a dma_rmb() after the call to 
stmmac_rx_status() ?

Yes. I removed the debug print added the barrier, but that did not help.

So, I was finally able to setup NFS using your replicated setup and I 
can't see the issue :(

The only difference I have from yours is that I'm using TCP in NFS 
whilst you (I believe from the logs), use UDP.

You do have flow control active right ? And your HW FIFO size is >= 4k ?

So I tried TCP by setting the kernel boot params to 'nfsvers=3' and
'proto=tcp' and this does appear to be more stable, but not 100% stable.
It still appears to fail in the same place about 50% of the time.

> You do have flow control active right ? And your HW FIFO size is >= 4k ?

How can I verify if flow control is active?

The documentation for this device indicates a max transfer size of 16kB
for TX and RX.

You can check it by dumping register MTL_RxQ_Operation_Mode (0xd30).

Can you also add IOMMU debug in file "drivers/iommu/iommu.c" ?

Where would be the appropriate place to dump this? After probe? Maybe
best if you can share a code snippet of where to dump this.

You can find a boot log here:

With this patch it appears to boot fine. So far no issues seen.

Thank you for testing.

Hi Catalin and Will,

Sorry to add you in such a long thread but we are seeing a DMA issue 
with stmmac driver in an ARM64 platform with IOMMU enabled.

The issue seems to be solved when buffers allocation for DMA based 
transfers are *not* mapped with the DMA_ATTR_SKIP_CPU_SYNC flag *OR* 
when IOMMU is disabled.

Notice that after transfer is done we do use 
dma_sync_single_for_{cpu,device} and then we reuse *the same* page for 
another transfer.

Can you please comment on whether DMA_ATTR_SKIP_CPU_SYNC can not be used 
in ARM64 platforms with IOMMU ?

In terms of what they do, there should be no difference on arm64 between:

dma_map_page(..., dir);
...
dma_unmap_page(..., dir);

and:

dma_map_page_attrs(..., dir, DMA_ATTR_SKIP_CPU_SYNC);
dma_sync_single_for_device(..., dir);
...
dma_sync_single_for_cpu(..., dir);
dma_unmap_page_attrs(..., dir, DMA_ATTR_SKIP_CPU_SYNC);

provided that the first sync covers the whole buffer and any subsequent 
ones cover at least the parts of the buffer which may have changed. Plus 
for coherent hardware it's entirely moot either way.

Given Jon's previous findings, I would lean towards the idea that 
performing the extra (redundant) cache maintenance plus barrier in 
dma_unmap is mostly just perturbing timing in the same way as the debug 
print which also made things seem OK.

Thanks for confirming. That's indeed what stmmac is doing when buffer is 
received by syncing the packet size to CPU.

Mikko said that Tegra186 is not coherent so we have to explicit flush 
pipeline but I don't understand why sync_single() is not doing it ...

Jon, can you please remove *all* debug prints, hacks, etc ... and test 
this one in attach with plain -net tree ?

So far I have just been testing on the mainline kernel branch. The issue
still persists after applying this on mainline. I can test on the -net
tree, but I am not sure that will make a difference.

I looked at netsec implementation and I noticed that we are syncing the 
old buffer for device instead of the new one. netsec syncs the buffer 
for device immediately after the allocation which may be what we have to 
do. Maybe the attached patch can make things work for you ?
