This resulted in the 4-address -WDS mode not getting enabled for a STA. This could occur in particular -when operating under heavy load and the STA is reconnecting to the same -AP in a sequence where Deauthentication frame is followed immediately by -Authentication frame and the driver event processing gets delayed due to -removal of the previous netdev taking time in the middle of this -sequence. - -Fix this by recording a pending item for 4-address WDS enabling if the -NL80211_CMD_UNEXPECTED_4ADDR_FRAME event would have been dropped due to -incompleted association and then process this pending item if the TX -status for the (Re)Association Response frame is received and it shows -that the frame was acknowledged. - -Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> ---- - ---- a/src/ap/ieee802_11.c -+++ b/src/ap/ieee802_11.c -@@ -2634,6 +2634,8 @@ static void handle_assoc(struct hostapd_ - taxonomy_sta_info_assoc_req(hapd, sta, pos, left); - #endif /* CONFIG_TAXONOMY */ - -+ sta->pending_wds_enable = 0; -+ - fail: - /* - * In case of a successful response, add the station to the driver. -@@ -3248,6 +3250,14 @@ static void handle_assoc_cb(struct hosta - - hostapd_set_sta_flags(hapd, sta); - -+ if (!(sta->flags & WLAN_STA_WDS) && sta->pending_wds_enable) { -+ wpa_printf(MSG_DEBUG, "Enable 4-address WDS mode for STA " -+ MACSTR " based on pending request", -+ MAC2STR(sta->addr)); -+ sta->pending_wds_enable = 0; -+ sta->flags |= WLAN_STA_WDS; -+ } -+ - if (sta->flags & WLAN_STA_WDS) { - int ret; - char ifname_wds[IFNAMSIZ + 1]; -@@ -3512,10 +3522,22 @@ void ieee802_11_rx_from_unknown(struct h - struct sta_info *sta; - - sta = ap_get_sta(hapd, src); -- if (sta && (sta->flags & WLAN_STA_ASSOC)) { -+ if (sta && -+ ((sta->flags & WLAN_STA_ASSOC) || -+ ((sta->flags & WLAN_STA_ASSOC_REQ_OK) && wds))) { - if (!hapd->conf->wds_sta) - return; - -+ if ((sta->flags & (WLAN_STA_ASSOC | WLAN_STA_ASSOC_REQ_OK)) == -+ WLAN_STA_ASSOC_REQ_OK) { -+ wpa_printf(MSG_DEBUG, -+ "Postpone 4-address WDS mode enabling for STA " -+ MACSTR " since TX status for AssocResp is not yet known", -+ MAC2STR(sta->addr)); -+ sta->pending_wds_enable = 1; -+ return; -+ } -+ - if (wds && !(sta->flags & WLAN_STA_WDS)) { - int ret; - char ifname_wds[IFNAMSIZ + 1]; ---- a/src/ap/sta_info.h -+++ b/src/ap/sta_info.h -@@ -115,6 +115,7 @@ struct sta_info { - unsigned int radius_das_match:1; - unsigned int ecsa_supported:1; - unsigned int added_unassoc:1; -+ unsigned int pending_wds_enable:1; - - u16 auth_alg; - |
