[pkg-wpa-devel] Bug#638789: wpasupplicant: wpa_supplicant not waiting for PID file

Package: wpasupplicant
Version: 0.7.3-0ubuntu1
Severity: important
We just moved from WEP to WPA and started using wpa_supplicant
on ~30 Ubuntu 11.04 machines. Almost all machines had trouble
connecting as ifup failed when starting wpa_supplicant. The
error went something like:
cat: /var/run/wpa_supplicant.wlan0.pid: No such file or directory
Adding a wait condition in /etc/wpa_supplicant/functions.sh
did the trick:
--- functions.sh
+++ functions.sh.new

This may not be the most elegant way of solving the issue,
but it works and the condition is (almost) always met. That
is, ifup -v wlan0 prints "Waiting for pid file.."
We experienced this with two types of cards:
* USB Proxim Wireless ORiNOCO 802.11a/b/g/n using
Kernel modules: carl9170, ar9170usb
* PCI CNet CWP-905 (Ralink chipset)
Kernel modules: rt2800lib, rt2x00pci, rt2x00lib
In both cases I use the wext driver for wpa_supplicant.
A Google search found some other folks having similar
problems, for example: http://ubuntuforums.org/showthread.php?t=1764073
Thanks,
Björn Swift
