Hi All, I am using a Raspberry PI with 4.14y kernel on Raspbian and running wpa_supplicant 2.9-release version. I could see following observation and would like to confirm whether these are to be handled in Wi-Fi driver or in user space? 1] There are two interfaces on running wpa_supplicant. The wlan0 and p2p-dev-wlan0. I am using wlan0 interface for my operations on DPP. On issuing the DPP listen command, I observed that the DPP listen stops working after 5 seconds when the event CANCEL_REMAIN_ON_CHANNEL is received. I could see that REMAIN_ON_CHANNEL event is coming on wlan0 but the CANCEL_REMAIN_ON_CHANNEL event is coming on p2p-dev-wlan0. This cause the DPP listen to stop working as the cookie check fails since cookie comparison is done with the p2p-dev-wlan0 interface whereas cookie value is actually set on wlan0. Is there any way to get wlan0 listen continously ? Log : ------ nl80211: Drv Event 55 (NL80211_CMD_REMAIN_ON_CHANNEL) received for wlan0 nl80211: Remain-on-channel event (cancel=0 freq=2412 channel_type=0 duration=5000 cookie=0x1 (match)) wlan0: Event REMAIN_ON_CHANNEL (19) received Off-channel: Send Action callback (without_roc=0 pending_action_tx=(nil) pending_action_tx_done=0) P2P: remain-on-channel callback (off_channel_freq=2412 pending_listen_freq=0 roc_waiting_drv_freq=0 freq=2412 duration=5000) P2P: Ignore remain-on-channel callback (off_channel_freq=2412 pending_listen_freq=0 freq=2412 duration=5000) nl80211: Drv Event 56 (NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL) received for p2p-dev-wlan0 nl80211: Remain-on-channel event (cancel=1 freq=2412 channel_type=0 duration=0 cookie=0x1 (unknown)) --------------------------------End of Log------------------------------------------------------- 2] Anyway, since the DPP listen works for the first 5 seconds, I could initiate an authentication request from AP. The AP got an authentication response from the supplicant. However all the authentication response received where having the MAC address of p2p-dev-wlan0 even though interface is selected wlan0 in wpa_cli? Is there any way to send authentication frames from wlan0 interface by disabling virtual interface p2p-dev-wlan0?
