Public bug reported:
Ubuntu 14.04 LTS
wpasupplicant 2.1-0ubuntu1
wpa_supplicant is writing to syslog every couple of minutes. Example

The message seems harmless as far as the network is concerned, meaning
there is no problem with the wifi connection. But it's spamming the
syslog, making it very difficult to find any other thing there, and it's
generating constant writes to disk, and an unnecessarily large syslog
file.
