io-pkt leak data section - ppc8260 ethernet driver
Hello,
we do see on our system that io-pkt while running shows in different scenarios a memory leak. The memory in the data
section grows until the system has no resources (RAM) left and crashes!
----------------------------------------------------------------------------------
QNX Version used:
------------------------------------
QNX6.5 SP2 - PPC Platform
NIC Driver uses:
------------------------------------
from BSP 8260 pq2fads (QNX PQ2FADS BSP V1.0.2 (File revision: 1.43))
Start sequence of drivers (extract from a start up script):
------------------------------------
mount -T io-pkt -o channel=1,mac=$MAC1 devn-ppc8260-nxa.so
mount -T io-pkt -o channel=2,mac=$MAC2 devn-ppc8260-nxa.so
mount -T io-pkt -o channel=3,mac=$MAC3 devn-ppc8260-nxa.so
netmanager -r all -f $NETCONFIG
mount -T io-pkt -o bind=ip0,resolve=dns,resolve=autoresolve /usr/lib/lsm-qnet.so
----------------------------------------------------------------------------------
Other embedded sysetm are also connected on the network. If we now perform ls /net/$NODENAME the new node do appear.
By simple performing the "df -h" we can reproduce the leak.
The issue is, that our application does not execute this command - but we can see that ~4.5 hours the data section
(pidin -mem) of io-pkt do increase by 4kBytes.
Any help is welcome, also if more information is needed - please let me know
Kind Regards
Thomas L.

Re: io-pkt leak data section - ppc8260 ethernet driver
This is most probably a driver issue, but this driver wasn¹t written by
QNX and we don¹t have the source code.

Hi,
if needed, wanted or allowed from QNX point of view - I can attach the driver code.

Re: io-pkt leak data section - ppc8260 ethernet driver
If you don¹t have a support contract with QNX, you will have to speak to
your sales rep to sort something out.

Re: io-pkt leak data section - ppc8260 ethernet driver
Some more test results,
I just started the OS and killed all Ethernet related things.
I started io-pkt-v4 again and kept a script in the background running:
===================
while [ 0 -lt 1 ]
do
df >> /mnt/flash.log
sleep 1
done

Re: io-pkt leak data section - ppc8260 ethernet driver
io-pkt will allocate memory as it is needed, so the data size will carry
on increasing, but should stabilize after a while.

Re: io-pkt leak data section - ppc8260 ethernet driver
Understood,
I will keep the system/test running over night and will let you know if the memory stabalized.
If yes - good, then I have to look into another direction, BUT IF NOT?
Again no network driver is mounted as you can see in the pidin log, so for me the original request/answer that there is
a bug in the driver itself can be crossed out - as it is not mounted/loaded/started....
Thanks for the replies
Kind Regards
Thomas

Re: io-pkt leak data section - ppc8260 ethernet driver
Hello,
kept on running the test.
io-pkt.-v4 data section of the memory is NOT settling down!
====================
# pidin -l -d 100 -p io-pkt-v4 mem
pid tid name prio STATE code data stack
208330770 1 usr/bin/io-pkt-v4 21r SIGWAITINFO 572K 4184K 4096(516K)*
208330770 2 usr/bin/io-pkt-v4 21r RECEIVE 572K 4184K 8192(132K)
====================
script code:
===========
while [ 0 -lt 1 ]
do
df -h > /dev/null
done
===========
what can cause the system/io-pkt to eat up memory while executing this script. If we find out the reason, then I can
have a look into our application what might cause the same issue.
Thanks in advance
Thomas L.

Re: io-pkt leak data section - ppc8260 ethernet driver
What version of the O/S are you running, and what is the command line you
are using to start io-pkt? The output from pidin would also be useful.

Hi,
we do have two system running
1. QNX 6.5.0 2010/07/09-14:35:59EDT
# use -i io-pkt-v4-hc
NAME=io-pkt-v4-hc
DESCRIPTION=TCP/IP protocol module.

2. QNX 6.5.0 2012/06/20-13:49:31EDT
# use -i io-pkt-v4
NAME=io-pkt-v4
DESCRIPTION=TCP/IP protocol module.

STATE=stable
HOST=pspbuildvm
USER=pspbuild
VERSION=650SP1-4004

on both systems we start io-pkt-v4 the following way:
io-pkt-v4
mount -T io-pkt -o channel=1,mac=$MAC1 devn-ppc8260-nxa.so
mount -T io-pkt -o channel=2,mac=$MAC2 devn-ppc8260-nxa.so

mount -T io-pkt -o bind=ip0,resolve=dns,resolve=autoresolve /usr/lib/lsm-qnet.so
Both systems showing the same leak behavior.

Re: io-pkt leak data section - ppc8260 ethernet driver
Unfortunately there is nothing we can do about this without getting access
to your BSP as well as the source to the io-pkt driver. We cannot give you
the latest io-pkt, as it will require the network driver to be re-compiled
with the latest libc and libsocket. Your best bet is to contact your sales
rep and make a formal request to have this work done.

Re: io-pkt leak data section - ppc8260 ethernet driver
Hi all,
I just proofed that this issue is also present on an X86 machine!
If downloaded the vmware image from (http://www.qnx.com/download/feature.html?programid=23665) and executed the same
scripte
======================
while [ 0 - lt 1 ]
do
df >> /dev/null
done
======================
While monitoring via pidin the io-pkt module (pidin -l -d 100 -p io-pkt-v4-hc mem) I can see the memory is increasing,
increasing, increasing, increasing, ...
See attached screenshot.
I think it is now prooven it has nothing todo with my BSP or modified network driver. It is a general issue!
Need help to identify which is causing this memory leak - relation of DF command and io-pkt?
Then I would know what we are doing WRONG in our application which shows the same behavior.
Thank in advance
If needed - how can I file this defect directly to the QNX development team?
Kind Regards

Re: io-pkt leak data section - ppc8260 ethernet driver
Well then there must be something strange going on on your systems, as I
have a 6.5.0 SP1 x86 machine and have no problem with the data segment
increasing.

Re: io-pkt leak data section - ppc8260 ethernet driver
... ???? it the vmware X86 provided by QNX, downloaded - started. Nothing else done?
I don't really know what I do wrong here?

Re: io-pkt leak data section - ppc8260 ethernet driver
Does the x86 data segment on the x86 machine stabilize after a while?

Re: io-pkt leak data section - ppc8260 ethernet driver
No. I just kept it running and it eating up already 5MB
I'm just about to test the same on QNX6.6.0 and let you know

Re: io-pkt leak data section - ppc8260 ethernet driver
Just used the QNX SDP 6.6.0 runtime ISO for VMware [or virtual machine] to install a virtual machine.
If I do the same test in here
io-pkt-v4-hc is stable! 504K and stable!
But as we have a PPC architecture on or target I can't switch I have to stick with 6.5

Re: io-pkt leak data section - ppc8260 ethernet driver
Your issue does not reproduce for me on 6.5 VMware image. Are you sure the number of processes stays constant? Copies
of sh are being left in memory?

Re: io-pkt leak data section - ppc8260 ethernet driver
I use the vmware QNX 6.5.0 2012/06/20-13:50:50EDT x86pc x86
Number of processes is constant ~40 (39-40)
Number of threads (pidin info) constant
O.k with every call of "df" it does get a new process ID but the calling shell stays the same.
Of all processes only io-pkt-v4-hc do increase

What is your "df" output? I can't see any relationship of df to network UNLESS there is a sharepoint mounted...

Re: io-pkt leak data section - ppc8260 ethernet driver
My io-pkt-v4-hc is exactly the same. Has to be something with the network - but I don't see how it is related to the "
df" call you are making.
What is you replace "df >>/dev/null" with "ls >>/dev/null"... does it have to be "df" to see the leak?

RE: io-pkt leak data section - ppc8260 ethernet driver
A capture with tracelogger should answer all these questions? Assuming the VM is using the instrumented kernel ?
