Hi,
When trying to do two consecutive scans from a lua script, a segfault in
libiwinfo.so occurs.
Example:
# lua -l 'iwinfo' -e "iw = iwinfo['nl80211'] ; iw.scanlist('wlan0') ;
iw.scanlist('wlan0');"
Segmentation fault
This patch causes iwinfo to only 'ATTACH' to unsolicited wpa_supplicant events,
when they are
expected.
