Hi,
since a short while (maybe kernel 2.6.31, not sure), wpa_supplicant (in
roamding mode) does not start when the rfkill switch for my wireless
interface is enabled:
$ /sbin/wpa_supplicant -s -B -P /var/run/wpa_supplicant.wlan0.pid -i wlan0 -W
-D wext -c /etc/wpa_supplicant/wpa_supplicant.conf
SIOCSIFFLAGS: Unknown error 132
strace output:
munmap(0x7f145716f000, 4096) = 0
socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4
socket(PF_NETLINK, SOCK_RAW, 0) = 5
bind(5, {sa_family=AF_NETLINK, pid=0, groups=00000001}, 12) = 0
ioctl(4, SIOCGIFFLAGS, {ifr_name="wlan0",
ifr_flags=IFF_BROADCAST|IFF_MULTICAST}) = 0
ioctl(4, SIOCSIFFLAGS, {ifr_name="wlan0", ???}) = -1 ERFKILL (Unknown error 132)
dup(2) = 6
fcntl(6, F_GETFL) = 0x8002 (flags O_RDWR|O_LARGEFILE)
fstat(6, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 3), ...}) = 0
Judging from the strace output, the kernel has a new error condition for
rkill-disabled interfaces that wpa_supplicant does not handle.
This bug causes wpa_supplicant to exit and it is available any more when
the killswitch is disabled. I have to manually run
$ ifdown --force wlan0; ifup wlan0
to enable it again.
Greetings,
Joachim
