hey, am having a small problem with porting wifi to a my device.
This is my config:
wifi.c (in libhardware_legacy)
static const char IFACE_DIR[] = "/data/misc/wifi/
wpa_supplicant";
static const char SUPP_CONFIG_TEMPLATE[]= "/system/etc/wifi/
wpa_supplicant.conf";
static const char SUPP_CONFIG_FILE[] = "/data/misc/wifi/
wpa_supplicant.conf";
wpa_supplicant.conf
update_config=1
ctrl_interface=DIR=/data/misc/wifi/wpa_supplicant
init.rc
mkdir /data/misc/wifi 0770 wifi wifi
chmod 0770 /data/misc/wifi
chmod 0660 /data/misc/wifi/wpa_supplicant.conf
chown wifi wifi /data/misc/wifi/wpa_supplicant.conf
mkdir /system/etc/wifi 0770 wifi wifi
chmod 0770 /system/etc/wifi
chmod 0660 /system/etc/wifi/wpa_supplicant.conf
chown wifi wifi /system/etc/wifi/wpa_supplicant.conf
# wpa_supplicant socket (unix socket mode)
mkdir /data/misc/wifi/wpa_supplicant 0771 wifi wifi
chmod 0771 /data/misc/wifi/wpa_supplicant
chown wifi wifi /data/misc/wifi/wpa_supplicant
service wpa_supplicant /system/bin/wpa_supplicant -dd -Dwext -
ieth0 -c /system/etc/wifi/wpa_supplicant.conf
group system wifi inet
disabled
oneshot
Notes:
- Wifi driver/module loads properly (wifi.c, dmesg, iwconfig say so)
- Logcat reports:
WifiHW: Unable to open connection to supplicant on "eth0": No such
file or directory (~ 4 times then unloads wifi)
- Manually loading the driver/module and
> running wpa_supplicant (as the service above) gives not errors &
proper logcat
although it does make this dmesg entry:
<4>[735, wpa_supplicant] [ 1479.081526] Enter
wl_control_wl_start
<4>[735, wpa_supplicant] [ 1479.081567] Exited
wl_control_wl_start
> running 'wpa_cli -p /data/misc/wifi/wpa_supplicant' gives
Selected interface 'eth0'
Could not connect to wpa_supplicant - re-trying
and forever remains this way
> running 'iwlist scan' works and shows wi-fi networks
My guess would be that my permissions are wrong, but i have been
double checking with 'ls -l' and they seem ok.
The wpa_supplimentary socket 'eth0' does get created so it exists.
My guess would be that the android wifi backend runs as a specific
user other than wifi!?
