Hi jouni
This letter may have some unsuitable word, please forgive my bad English skill.
Recently I construct a WDS network, using hostapd. Sometimes when the WDS_client restart. The wpa_supplicant connect active will failed. I diff the success log and failed log and found when the pending EAPOL occur the connect failed.
can you give me some advice for this.
I found some code add to the back of pending EAPOL:

if (wpa_s->pending_eapol_rx) {
	struct os_reltime now, age;
	os_get_reltime(&now);
	os_reltime_sub(&now, &wpa_s->pending_eapol_rx_time, &age);
	if (age.sec == 0 && age.usec < 100000 &&
	    os_memcmp(wpa_s->pending_eapol_rx_src, bssid, ETH_ALEN) ==
	    0) {
		wpa_dbg(wpa_s, MSG_DEBUG, "Process pending EAPOL "
			"frame that was received just before "
			"association notification");
		wpa_supplicant_rx_eapol(
			wpa_s, wpa_s->pending_eapol_rx_src,
			wpabuf_head(wpa_s->pending_eapol_rx),
			wpabuf_len(wpa_s->pending_eapol_rx));
	}
	wpabuf_free(wpa_s->pending_eapol_rx);
	wpa_s->pending_eapol_rx = NULL;
}

if ((wpa_s->key_mgmt == WPA_KEY_MGMT_NONE ||
     wpa_s->key_mgmt == WPA_KEY_MGMT_IEEE8021X_NO_WPA) &&
    wpa_s->current_ssid &&
    (wpa_s->drv_flags & WPA_DRIVER_FLAGS_SET_KEYS_AFTER_ASSOC_DONE)) {
	/* Set static WEP keys again */
	wpa_set_wep_keys(wpa_s, wpa_s->current_ssid);
}

#ifdef CONFIG_IBSS_RSN
if (wpa_s->current_ssid &&
    wpa_s->current_ssid->mode == WPAS_MODE_IBSS &&
    wpa_s->key_mgmt != WPA_KEY_MGMT_NONE &&
    wpa_s->key_mgmt != WPA_KEY_MGMT_WPA_NONE &&
    wpa_s->ibss_rsn == NULL) {
	wpa_s->ibss_rsn = ibss_rsn_init(wpa_s, wpa_s->current_ssid);
	if (!wpa_s->ibss_rsn) {
		wpa_msg(wpa_s, MSG_INFO, "Failed to init IBSS RSN");
		wpa_supplicant_deauthenticate(
			wpa_s, WLAN_REASON_DEAUTH_LEAVING);
		return;
	}

	ibss_rsn_set_psk(wpa_s->ibss_rsn, wpa_s->current_ssid->psk);
}
#endif /* CONFIG_IBSS_RSN */
// gawhesheep added this, debug comment.
// This happen unnormally in failed log.
wpas_wps_notify_assoc(wpa_s, bssid);

if (data) {
	wmm_ac_notify_assoc(wpa_s, data->assoc_info.resp_ies,
			    data->assoc_info.resp_ies_len,
			    &data->assoc_info.wmm_params);

	if (wpa_s->reassoc_same_bss)
		wmm_ac_restore_tspecs(wpa_s);
}

I'm not sure what ture happened. I guess it's due to new added code.

wpas_wps_notify_assoc(wpa_s, bssid);

which add in this commit:

WPS: Maintain more AP state during WPS PIN iteration

Maintain state of WPS APs during iteration to find the correct AP for
WPS PIN operation when no specific BSSID is specified. This information
can be used for optimizing the order in which the APs are tried. This
commit is only adding the collection of the information and more
detailed debug information to make debug logs more helpful in figuring
out how the AP selection order could be improved.

Can you create a mirror like several organizations/projects?

Example:

Thanks in advance.

hi, I have issues looking for help.

1.Below website was broken for several days.
Is anybody to fix it?

http://buildbot.w1.fi/hwsim/tests.php

2.some cases are unstable
For example:
p2p_service_discovery_external
I run this case on Debian for 40 times, and fail 2 times, all of other 38 times are pass.
I wonder whether the instability can be fixed.

I read the code src/drivers/driver_wext.c
at function: wpa_driver_wext_event_wireless
the client may receive a is_zero_ether_addr all 0 mac,
I want to ask how to make the client receive a "00:00:00:00:00:00" mac which seems a assiciation AP?

case SIOCGIWAP:
wpa_printf(MSG_DEBUG, "Wireless event: new AP: "
MACSTR,
MAC2STR((u8 *) iwe->u.ap_addr.sa_data));
*if (is_zero_ether_addr(
(const u8 ) iwe->u.ap_addr.sa_data) ||
os_memcmp(iwe->u.ap_addr.sa_data,
"\x44\x44\x44\x44\x44\x44", ETH_ALEN) ==
0) {
os_free(drv->assoc_req_ies);
drv->assoc_req_ies = NULL;
os_free(drv->assoc_resp_ies);
drv->assoc_resp_ies = NULL;
wpa_supplicant_event(drv->ctx, EVENT_DISASSOC,
NULL);

		} else {
			wpa_driver_wext_event_assoc_ies(drv);
			wpa_supplicant_event(drv->ctx, EVENT_ASSOC,
					     NULL);
		}
		break;

I can build and install hostapd, but I can't use hostapd as described in these docs -> https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md

Can you provide any tutorial or a document on creating a hostapd service?
I can't create a hostapd service by compiling and installing this hostapd

I have created a Raspberry Pi 3A+ prototype system consisting of a rover with camera and touch screen remote control that communicate across a Wi-Fi network. My expectation was to have the rover switch from our local Wi-Fi router to the remote control once it started hostapd at which point the rover streams video and shares sockets with the remote control through its access point.

In this current configuration, both RPis run arch linux arm without wpa_supplicant. The rover is the server that receives commands from the remote using sockets. I use netctl to switch wlan0 to the remote control's AP SSID when it appears using a 'iw dev wlan0 scan' command. While connected, the rover pings the remote control IP address to confirm it is connected. Should the ping fail or the AP SSID vanishes, the netctl call switches the rover back to the local Wi-Fi LAN.

Yesterday I confirmed the netctl switched the rover to the remote control access point correctly but once I shut down the local Wi-Fi router, the rover lost connection with the remote control and the streaming video stopped playing on the remote control.

At this point, I am not sure what to use to create this “subnetwork” solution so that these two RPi units communicate outside an internal Wi-Fi network. Do I need to purchase a separate miniature pocket Wi-Fi router or is there a way for the two RPis to communicate and stream video over their internal Wi-Fi chips?

I am open to any alternative suggestions or recommendations. If there is a site with this information, I will be appreciative of that recommendation. I searched but could not find a solution.
