Description Petter Reinholdtsen 2013-09-16 11:39:12 UTC 
Package: plasma-widget-networkmanagement
Version: 0.9.0.3-1
Severity: important
Tags: upstream

Dear Maintainer,

My KDE desktop based on Debian Wheezy is unstable.  After a few days,
the KDE panel stop working properly, and I have to log out and in
again to get back to work.  Clicking on the K menu do not have any
effect until 20-60 seconds later, and the icons like the battery and
network status are unresposive, with similar delays from mouse clicks.

I believe I tracked down the cause, which is that kded4 is running out
of file descriptors because it is leaking sockets.  When the problem
happen, the process have above 1020 files open.

With 23010 as the pid of kded4, I used this one-liner to to track the
number of open files and the distribution across different types:

  ls -l /proc/23010/fd|wc -l ; ls -l /proc/23010/fd|rev|cut -d\[ -f2|awk '{print
+$1}'|rev|sort|uniq -c

It show that approximately 2.5 sockets are leaked per minute at the
moment.

With the good help of pinotree on #debian-kde, I was able to find the
most likely part responsible, and it seem to be the "NetworkManager
User Settings service" available in the System Settings->Startup and
Shutdown->Service Manager menu.  When I disable it (and run kdeinit4
to make sure the change take effect), the number of open sockets
stopped increasing.  When I enable it again, the number of open
sockets start to increase.

When I now had an idea about the affected system, I tried to disable
wifi using the check box in the network-manager control panel, and the
number of open sockets stayed stable again.

Where I am at the moment, I use TP ethernet, and while there are
several wifi networks around, non of them are really working for me.
But I do notice network-manager try to connect over and over again to
a few of them.

This make me suspect that the plasma-widget-networkmanagement code
fail to close some socket when connecting to a wifi network fail.

This problem was also reported to Debian as http://bugs.debian.org/723092 .

Reproducible: Always

Disable emmiting wifi's signal strenght

Hmmm the only think I can think of that could generate a 2.5 sockets per minute would be the signal strengh dbus signal. You can check if disabling emmiting the signal strenght signal solves this problem? Use the attached patch for that. 

Keept in mind that Plasma NM does not explicitly open sockets. If the patch above workarounds the problem then the real problem is probably in dbus or QtDBus.

Did not make any difference.  Still leaking sockets.

Note that the computer is trying over and over to connect to a wifi
network (essid matches one set to auto, but the network where I am
located is not allowing me to connect).

I am happy to test other things too.  Perhaps we should meet on IRC to
speed up the round trip time?  I got a few hours now before I leave the
office for the day.
Comment 3 Petter Reinholdtsen 2013-09-17 11:11:22 UTC 
I visited #kde-devel and got some help from aseigo.  He suggested to
disable the GUI widget and the "NetworkManager User Settings Service"
service, and try to connect to the wifi network using "nmcli con list"
and "nmcli con up id" to see if the socket leak is in network-manager
or in the kde module.

I first disabled the GUI widget, and tried to connect.  The sockets
still leaked when trying to connect:


% nmcli con list|grep ntnu
Auto ntnu 7b9a986e-0b25-4314-9d39-c33a9047a262   802-11-wireless   ma. 16. sep. 2013 kl. 13.50 +0200

Then I visited system settings and disabled "NetworkManager User
Settings Service".  This caused kded4 to crash.  This is the
backtrace:

Next, I restarted kded4 by running kdeinit4, and the number of sockets
were back to 7.  Trying to connect to the wifi network using the nmcli
command above did not increase the number of sockets.

Btw, I use this program to count sockets and open files:

#!/bin/sh
pid=$(pidof kded4)
ls -l /proc/$pid/fd|wc -l; ls -l /proc/$pid/fd|rev|cut -d\[ -f2|awk '{print $1}'|rev|sort|uniq -c

Anything more I can do to help fix this?
Comment 4 Petter Reinholdtsen 2013-09-19 08:28:34 UTC 
It occured to me that perhapd gdb could help figuring out what is
leaking sockets, so I rebuilt the deb with DEB_BUILD_OPTIONS=nostrip,
installed plasma-widget-networkmanagement_0.9.0.3-1_amd64.deb and
plasma-widget-networkmanagement-dbg_0.9.0.3-1_amd64.deb, restarted
kded4, connected using gdp -p <pid> and added a break on the socket()
system call.  This gave me backtraces.

Here are some example backtraces.

Anything more I can do to help fix this?
Comment 5 Lamarque V. Souza 2013-09-19 09:54:45 UTC 
According to the backtrace this is a bug in Solid::Device, CC'ing afiestas@kde.org so he can comment on that.
Comment 6 Lamarque V. Souza 2013-09-19 10:02:51 UTC 
I have just looked at NetworkInterface::isWireless() in kdelibs/solid/solid/backends/udev/udevnetworkinterface.cpp and it does not close the QFile object it uses to check if the interface is wireless. Maybe that is the source of the problem.

I got another idea to try to pinpoint the problem.  I ran
'valgrind --track-fds=yes kdeinit4' to enable file descriptor
tracking, tracked down which of the sub-processes was leacking
sockets, tried a few times to connect to the wifi network to leak a
handfull of sockets, and then killed the process.  Valgrind then
reported this:

It sure look like Solid::Device::description() is the source of the
leak.

As far as I can tell, it fixes the problem.  After rebuilding kde4lib
and installing the new libsolid4 package, the number of open sockets
stay on 6 also when I try using "time nmcli con up uuid
7b9a986e-0b25-4314-9d39-c33a9047a262" to reconnect to the wifi network
that reject my connection.

But I had to adjust the patch slightly, including the <unistd.h>
header with the close() definition:
