[pkg-wpa-devel] Bug#548694: wpasupplicant: wpa_supplicant process keeps running after "ifdown wlan0"

[Sven Joachim]

Package: wpasupplicant
Version: 0.6.9-3
Severity: important

After the upgrade of udev to version 146-3, "ifdown wlan0" no longer
kills the wpa_supplicant process.  The result is that it fills the
syslog with "Failed to initiate AP scan" messages and that during
shutdown the /var and /usr filesystems are busy.

Here are the stanzas of /etc/network/interfaces:

,----
| allow-hotplug wlan0
| iface wlan0 inet dhcp
|       wpa-driver wext
|       wpa-ap-scan 1
|       wpa-scan-ssid 1
|       wpa-ssid "hidden"
|       wpa-proto WPA RSN
|       wpa-pairwise CCMP
|       wpa-group CCMP
|       wpa-key-mgmt WPA-PSK
|       wpa-psk "top secret"
