Workaround for random P2P device MAC in wpa_supplicant

[mraliec]

Download wpa_supplicant source as described in command.txt

Edit p2p_supplicant.c function wpas_p2p_mac_setup
After:
u8 addr[ETH_ALEN] = {0};
Add two lines:
os_memcpy(wpa_s->own_addr, wpa_s->conf->p2p_device_persistent_mac_addr, ETH_ALEN);
os_memcpy(wpa_s->global->p2p_dev_addr, wpa_s->conf->p2p_device_persistent_mac_addr, ETH_ALEN);

Add following option to wpa_supplicant.conf
p2p_device_persistent_mac_addr= wanted mac address

Now P2P Go device always = p2p_device_persistent_mac_addr
For example my conf:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=0
country=US
persistent_reconnect=1
p2p_device_persistent_mac_addr=3e:50:84:9d:7e:11
mac_addr=0
p2p_interface_random_mac_addr=0
network={
ssid="DIRECT-AO"
bssid=3e:50:84:9d:7e:a5
psk="yrf6u5IC"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
auth_alg=OPEN
mode=3
disabled=2
}
