Hi Jouni, For "device_ap_sme" devices, the ap_sta_disconnect call in supplicant results in two calls to wpa_driver_nl80211_sta_remove. ap_sta_disconnect > hostapd_drv_sta_deauth > wpa_driver_nl80211_sta_remove ap_sta_disconnect > ap_sta_deauth_cb_timeout > ap_sta_remove > hostapd_drv_sta_remove The ap_sta_deauth_cb_timeout is invoked immediately (timeout of [0,0]) for device_ap_sme devices. The hostapd_drv_sta_deauth call can be avoided for devices without WPA_DRIVER_FLAGS_DEAUTH_TX_STATUS set. ##### Sample logs +++++++++++++++++++++++++++++++++++++++++++++++++ Example logs D/wpa_supplicant(16311): p2p-wlan0-0: IEEE 802.1X: Force disconnection after EAP-Failure D/wpa_supplicant(16311): nl80211: sta_remove -> DEL_STATION p2p-wlan0-0 02:90:4c:74:40:14 --> 0 (Success) <====================== 1st call D/wpa_supplicant(16311): ap_sta_disconnect: reschedule ap_handle_timer timeout for 02:90:4c:74:40:14 (5 seconds - AP_MAX_INACTIVITY_AFTER_DEAUTH) D/wpa_supplicant(16311): IEEE 802.1X: 02:90:4c:74:40:14 BE_AUTH entering state IDLE D/wpa_supplicant(16311): IEEE 802.1X: 02:90:4c:74:40:14 AUTH_PAE entering state INITIALIZE D/wpa_supplicant(16311): EAP: EAP entering state DISABLED D/wpa_supplicant(16311): Removing STA 02:90:4c:74:40:14 from kernel driver D/wpa_supplicant(16311): nl80211: sta_remove -> DEL_STATION p2p-wlan0-0 02:90:4c:74:40:14 --> 0 (Success) <====================== 2nd call D/wpa_supplicant(16311): hostapd_logger: STA 02:90:4c:74:40:14 - MLME-DEAUTHENTICATE.indication(02:90:4c:74:40:14, 23) D/wpa_supplicant(16311): hostapd_logger: STA 02:90:4c:74:40:14 - MLME-DELETEKEYS.request(02:90:4c:74:40:14) ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Signed-off-by: Jithu Jance <jithujance@xxxxxxxxx> --- src/ap/sta_info.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/ap/sta_info.c b/src/ap/sta_info.c index c36842b..c9b6578 100644 --- a/src/ap/sta_info.c +++ b/src/ap/sta_info.c @@ -1198,7 +1198,8 @@ void ap_sta_disconnect(struct hostapd_data *hapd, struct sta_info *sta, if (sta == NULL && addr) sta = ap_get_sta(hapd, addr); - if (addr) + if (addr && (hapd->iface->drv_flags & + WPA_DRIVER_FLAGS_DEAUTH_TX_STATUS)) hostapd_drv_sta_deauth(hapd, addr, reason); if (sta == NULL) -- 1.9.1 _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
