wpa_supplicant 2.11 - thick-mac open AP won't pass data packets

[Doug Smith]

All,

Apologies in advance if this has already been addressed.

Found an issue using wpa_supplicant 2.11 (built with CONFIG_AP support) configured as an open AP.
After a station connects to the AP, data packets are not passed -- pings fail.

The issue occurs with a thick-mac radio due to the WPA_STA_AUTHORIZED flag not being pushed.

When the station connects, the AP handles the assoc event in wpa_supplicant_event_assoc():<wpa_supplicant/events.c>, and calls hostapd_notif_assoc():<src/ap/drv_callbacks.c>.
hostapd_notif_assoc call hostapd_set_sta_flags() to push the flags -- unfortunately the AUTHORIZED flag hasn't been set yet.
The AUTHORIZED flag isn't set until hostapd_new_assoc_sta() is called a few lines later.
hostapd_new_assoc_sta():<src/ap/hostapd.c> calls ap_sta_set_authorized() for the open AP -- unfortunately the flag isn't pushed.

One possible fix is to push the flag as follows:
diff --git a/src/ap/hostapd.c b/src/ap/hostapd.c
index c8ec1d624..d4a73510d 100644

+               // fix no ping -- push the authorized flag
+               hostapd_set_sta_flags(hapd, sta);
                os_get_reltime(&sta->connected_time);
                accounting_sta_start(hapd, sta);
        }
