[1.] One line summary of the problem:
Crash when timestamping outgoing PTP packets under heavy network load
(ppc, gianfar)
[2.] Full description of the problem/report:
I have a custom embedded platform running a QorIQ P2020 PPC processor
and Freescale eTSEC for gigabit Ethernet. When I have heavy network load
(full gigabit Ethernet usage), and send PTP Event packets with gianfar’s
hardware timestamping enabled, memory/stack corruption seems to occur,
leading to many different symptoms, including DMA API Debug warnings,
CPU stalls, and oopses/panics due to null pointer dereference or invalid
page access. The crash can also happen under lower load, but below
100MBps it can take hours for the issue to occur.
[3.] Keywords (i.e., modules, networking, kernel):
networking, ptp, ieee 1588, hardware timestamping, gianfar, ppc, p2020
[4.] Kernel information
[4.1.] Kernel version (from /proc/version):
# uname -a
Linux version 4.4.235 (jjurack@oh-val-eng-12) (gcc version 4.9.3
(crosstool-NG crosstool-ng-1.22.0) ) #13 SMP Thu Sep 10 08:28:37 EDT 2020
[4.2.] Kernel .config file:
linux.config is attached
[5.] Most recent kernel version which did not have the bug:
The latest version of this system to not have this crash was using
kernel 3.2 (Linux morlun 3.2.0 #1 SMP Fri Jun 10 12:43:28 PDT 2016 ppc
GNU/Linux). However, many other parts of our system have changed since
then and I have so far not been able to create modified versions of that
build for 1:1 comparison testing. I have gone back as far as 4.4.129 on
the 4.4 branch; that is where I first discovered the issue.
[6.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
Console logs from a few different crashes are attached (console{1..5}.log)
[7.] A small shell script or example program which triggers the
problem (if possible)
I have attached minimal programs that I used to generate network load
and send timestamped PTP packets:
* netdump.c generates network traffic.
* dump.sh runs 16 instances of netdump.
* test.py connects to the netdump instances from another system to
consume the traffic.
* hwts.c sends timestamped PTP packets.
To reproduce I usually do these steps:
* run dump.sh
* start test.py on another system
* run `hwts 32` to send 32 ptp packets
* a crash usually happens within 10-20 seconds
[8.] Environment
[8.1.] Software (add the output of the ver_linux script here)
$ scripts/ver_linux
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

[8.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
I’ve attached our system’s device tree source file (emx-2500.dts).
[X.] Other notes, patches, fixes, workarounds:
[X.1.] I have tried commenting gianfar.c:965 (priv->hwts_tx_en = 1;).
This causes the crash to disappear.
[X.2.] Just calling the SIOCSHWTSTAMP ioctl to turn on hardware
timestamping while under network load causes a DMA API Debug warning,
but does not seem to destabilize the system otherwise. I’m not sure if
this is the same issue or separate. Examples of this are included in
each console log, as well as below:

* [PATCH net] gianfar: Account for Tx PTP timestamp in the skb headroom
2020-09-14 13:53 PROBLEM: Crash when timestamping outgoing PTP packets under heavy network load (ppc, gianfar) James Jurack

1 sibling, 1 reply; 28+ messages in thread
From: Claudiu Manoil @ 2020-10-20 17:36 UTC (permalink / raw)
To: netdev; +Cc: David S . Miller, Jakub Kicinski, james.jurack
When PTP timestamping is enabled on Tx, the controller
inserts the Tx timestamp at the beginning of the frame
buffer, between SFD and the L2 frame header. This means
that the skb provided by the stack is required to have
enough headroom otherwise a new skb needs to be created
by the driver to accommodate the timestamp inserted by h/w.
Up until now the driver was relying on the second option,
using skb_realloc_headroom() to create a new skb to accommodate
PTP frames. Turns out that this method is not reliable, as
reallocation of skbs for PTP frames along with the required
overhead (skb_set_owner_w, consume_skb) is causing random
crashes in subsequent skb_*() calls, when multiple concurrent
TCP streams are run at the same time on the same device
(as seen in James' report).
Note that these crashes don't occur with a single TCP stream,
nor with multiple concurrent UDP streams, but only when multiple
TCP streams are run concurrently with the PTP packet flow
(doing skb reallocation).
This patch enforces the first method, by requesting enough
headroom from the stack to accommodate PTP frames, and so avoiding
skb_realloc_headroom() & co, and the crashes no longer occur.
There's no reason not to set needed_headroom to a large enough
value to accommodate PTP frames, so in this regard this patch
is a fix.

Claudiu, I think this may be papering over the real issue.
needed_headroom is best effort, if you were seeing crashes
the missing checks for skb being the right geometry are still
out there, they just not get hit in the case needed_headroom
is respected.
So updating needed_headroom is definitely fine, but the cause of
crashes has to be found first.

I agree Jakub, but this is a simple (and old) ring based driver. So the
question is what checks or operations may be missing or be wrong
in the below sequence of operations made on the skb designated for
timestamping?
As hinted in the commit description, the code is not crashing when
multiple TCP streams are transmitted alone (skb frags manipulation was
omitted for brevity below, and this is a well exercised path known to work),
but only crashes when multiple TCP stream are run concurrently
with a PTP Tx packet flow taking the skb_realloc_headroom() path.
I don't find other drivers doing skb_realloc_headroom() for PTP packets,
so maybe is this an untested use case of skb usage?
init:
dev->needed_headroom = GMAC_FCB_LEN;

netdev_tx_t gfar_start_xmit(struct sk_buff *skb, struct net_device *dev)
{

Try replacing this if () with skb_cow_head(). The skbs you're getting
are probably cloned.

That seems to be it(!), Jakub. With this change the test that was failing
immediately before passes now. I'm going to do some more tests, and
I'll send 2 stable fixes for v2 if everything is fine.
Not sure if this particular breakage was triggered by cloned skbs, though
probably timestamping skbs can get cloned, but could also be other aspect
/ side effect of using skb_realloc_headroom/skb_set_owner_w vs skb_cow_head,
as the 2 APIs differ in many ways.
Thanks for the help.

Claudiu

When PTP timestamping is enabled on Tx, the controller
inserts the Tx timestamp at the beginning of the frame
buffer, between SFD and the L2 frame header. This means
that the skb provided by the stack is required to have
enough headroom otherwise a new skb needs to be created
by the driver to accommodate the timestamp inserted by h/w.
Up until now the driver was relying on skb_realloc_headroom()
to create new skbs to accommodate PTP frames. Turns out that
this method is not reliable in this context at least, as
skb_realloc_headroom() for PTP frames can cause random crashes,
mostly in subsequent skb_*() calls, when multiple concurrent
TCP streams are run at the same time with the PTP flow
on the same device (as seen in James' report). I also noticed
that when the system is loaded by sending multiple TCP streams,
the driver receives cloned skbs in large numbers.
skb_cow_head() instead proves to be stable in this scenario,
and not only handles cloned skbs too but it's also more efficient
and widely used in other drivers.
The commit introducing skb_realloc_headroom in the driver
goes back to 2009, commit 93c1285c5d92
("gianfar: reallocate skb when headroom is not enough for fcb").
For practical purposes I'm referencing a newer commit (from 2012)
that brings the code to its current structure (and fixes the PTP
case).

When PTP timestamping is enabled on Tx, the controller
inserts the Tx timestamp at the beginning of the frame
buffer, between SFD and the L2 frame header. This means
that the skb provided by the stack is required to have
enough headroom otherwise it needs to be reallocated.
This patch is requesting enough headroom from the stack to
accommodate PTP frames in order to avoid reallocation whenever
possible.
There's no reason not to set needed_headroom to a large enough
value to accommodate PTP frames, so in this regard this patch
is a fix.

Hi Vladimir,
Can you try the above suggestion on your setup?
Thanks.

While it is something to be fixed - is anything other than pktgen
making use of IFF_TX_SKB_SHARING? Are you running pktgen, Vladimir?

It's either the dev_kfree_skb_any from the dma mapping error path or the one
from skb_cow_head()'s error path. A confirmation would help indeed.

Thanks for the hint Julian :) I'll try to see if it makes any
difference.
Just a wild guess, but maybe because the gianfar maintainer (or me) had
no idea about the existence of the flag, and because IFF_SKB_TX_SHARED
was added _after_ gianfar was already a thing (which it was since the
beginning of git), which is insane to begin with?
commit d8873315065f1f527c7c380402cf59b1e1d0ae36
Author: Neil Horman <nhorman@tuxdriver.com>

net: add IFF_SKB_TX_SHARED flag to priv_flags
Pktgen attempts to transmit shared skbs to net devices, which can't be used by
some drivers as they keep state information in skbs. This patch adds a flag
marking drivers as being able to handle shared skbs in their tx path. Drivers
are defaulted to being unable to do so, but calling ether_setup enables this
flag, as 90% of the drivers calling ether_setup touch real hardware and can
handle shared skbs. A subsequent patch will audit drivers to ensure that the
flag is set properly

Nope, just iperf3 TCP and PTP. The problem is actually with PTP, I've
been testing gianfar with just TCP for a long while.

And unsurprisingly given what Jakub said, it crashed again, even with
this change.

It says "consume", not "kfree", which in my mind would make it point
towards the only caller of consume_skb from the gianfar driver, i.e. the
dev_consume_skb_any that you just added.

#define dev_kfree_skb(a) consume_skb(a)
IIRC we did this because too many drivers used dev_kfree_skb
incorrectly and made the dropwatch output very noisy.

Now it fails like this too, under exactly the same traffic load:

FWIW ./scripts/decode_stacktrace.sh should point you right to the lines
of code if the build has enough debug info.

This is the patch:

are you sure you have it applied?

Actually? No, I didn't have it applied... I had thought that net had
been already merged into net-next, for some reason :-/
Let me run the test for a few more tens of minutes with the patch
applied.

Nice, so that's why the drop monitor never complains with my misplaced
dev_kfree_skb_any calls...

I find strange that the local TCP traffic can end up calling skb_realloc_headromm() in the old kernels.
Normally TCP reserves a lot of bytes for headers.
#define MAX_TCP_HEADER L1_CACHE_ALIGN(128 + MAX_HEADER)
It should accommodate the gianfar needs for additional 24 bytes,
even if LL_MAX_HEADER is 32 in your kernel build perhaps.

The test has been running for 30 minutes with the cherry-pick from net.
Sorry for the noise.

Hi,
The PTP packets need extra headroom and get reallocated, not TCP packets.
However if TCP streams are sent concurrently with PTP packets, and
skb_realloc_headroom() is used to reallocate PTP packets, we get these crashes.
If skb_cow_head() is used instead there's no crash.
