Automation of testing using mac80211_hwsim and Orbit

Hello Linux wireless users and kernel developers, Luis, John and Johannes,

this is the first status report of the "Automation of testing using
mac80211_hwsim and Orbit",
which is kindly sponsored by Google in the Summer of Code program and
mentored by the Linux Foundation.

http://www.linuxwireless.org/en/developers/GSoC/2009/Automation_of_testing
http://socghop.appspot.com/student_project/show/google/gsoc2009/linux_foundation/t124022664044

In the first week, I did implement a ground base for the testing
command line tool, which is written
in Python and will create statistics from the test set and later on
collect them and provide nice
statistics.

The installer, some basic commands and the parser are finished and I
did translate some of the available
tests (link from Luis) to Python. Moreover I have concentrated on
creating new tests and adding the loading
of kernel modules and setting options to the program.

By the end of the week, I did start to have some strange problems with
running hostapd (via nl80211) and using the
mac80211_hwsim kernel driver.

In case that someone did run into that problem with 2.6.30-rc5,6,7 +
latest git and latest git of hostap / wpa_supplicant,
it would be great to have a feedback on that.

One of the first tasks for the new week will be the creation of a wiki
documentation and also an introduction
how to check out the code, run some tests locally and also send
feedbacks / bug reports.
Like planned, I will continue to extend the test scenario by adding
more tests and also functionality to the command
line test tool.


Thanks, Georgy

It seems it would help if you explained what the strange problems are :)

True.  However, overall this is a nice report -- please do continue
to keep us informed!

Hi,

I had recompiled the kernel and tried to run hostapd again and now it
is working.
Still using the same settings. It seems that the problem has been
solved with the latest git pull.

That was the problem before (e.g. running the vlan example
hostapd.conf within hostap/mac80211_hwsim/tests/0002-vlan)
/opt/wifi/bin/hostapd hostapd.conf
Configuration file: hostapd.conf
nl80211: Failed to set interface wlan0 into AP mode
nl80211 driver initialization failed.
ELOOP: remaining socket: sock=3 eloop_data=0x977be10
user_data=0x977bfa0 handler=0x8076200

Thanks, Georgy

Hi again,

I was doing some additional tests and it seems that unloading the
mac80211_hwsim kernel module and reloading
it with the same configuration triggers the same error again.

Blacklisting some modules and disabling NetworkManager fixed the problem.
