Package: wpasupplicant
Version: 0.5.5-4
Severity: normal
Hello,
I just discovered that current wpa_supplicant just segfaults if the
specified interface is not available at all. Here the log and strace
log, as executed by ifup:
ifup eth1=kpax
ioctl[SIOCSIWPMKSA]: No such device
ioctl[SIOCSIWMODE]: No such device
Could not configure driver to use managed mode
ioctl[SIOCGIFFLAGS]: No such device
Could not set interface 'eth1' UP
ioctl[SIOCGIWRANGE]: No such device
ioctl[SIOCGIFINDEX]: No such device
