With wpa_supplicant in enforcing, wpa_cli doesn't work.
Denial:
type=1400 audit(1390597866.260:59): avc: denied { write } for pid=3410 comm="wpa_supplicant" name="wpa_ctrl_4852-1" dev="mmcblk0p28" ino=618993 scontext=u:r:wpa:s0 tcontext=u:object_r:wifi_data_file:s0 tclass=sock_file
After I9e35cc93abf89ce3594860aa3193f84a3b42ea6e and
I51b09c5e40946673a38732ea9f601b2d047d3b62, the /data/misc/wifi/sockets
directory is labeled properly. This change allows the communication
between the su domain and wpa.
Steps to reproduce:
Start wifi (so wpa_supplicant will run)
Start wpa_cli - it will hand
$ adb root
$ adb shell
# wpa_cli -g @android:wpa_wlan0
