[pkg-wpa-devel] Bug#471905: wpasupplicant: Wpasupplicant works only good if I start it with low Priority

[Gregor Adamczyk]

Package: wpasupplicant
Version: 0.6.3-1
Severity: important

Hi, if I start or configure wpasupplicant with normal priority, it is not possible to establish 
the WPA2 or WPA connection.

But a simple nice -10 in pre-up solve the problem completely.

The problem exists only in the daemon mode.

In debug mode I didn't have any problems.

Here is my temporary solve (work perfekt):

/etc/network/interfaces

allow-hotplug wlan0
iface wlan0 inet dhcp
pre-up nice -19 wpa_supplicant -B -i wlan0 -c "/etc/wpa_supplicant/wpa_supplicant.conf" -D wext; 
sleep 10;
post-down killall -q dhclient wpa_supplicant;

I worked at thy moment with ndiswrapper and the wext driver.

I test it on three different systems with stable, testing and unstable version of wpasupplicant.

Two slow systems haves the problem. (ndiswrapper WG111v3)

One new system with kernel rtl8187 driver works fine without any hotfixes.

Here is the udev rule from the worked system without any hotfixes:
# USB device 0bda:8187 (rtl8187)
SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:15:af:04:ac:37", ATTR{type}=="1", NAME="wlan0"

For this both systems i need the "nice" low priority.
# USB device 0846:4260 (ndiswrapper)
SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:1b:2f:d2:94:e8", ATTR{type}=="1", NAME="wlan0"

# USB device 0846:4260 (ndiswrapper)
SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:1b:2f:d2:94:f1", ATTR{type}=="1", NAME="wlan0"
