File wpa_supplicant-dont_report_empty_initial_scan.patch of Package wpa_supplicant
From: Dan Nicholson <dbn.lists@gmail.com> Date: Wed, 24 Sep 2008 09:51:08 +0000 (+0300) Subject: Don't post scan results when initial scan is emtpy X-Git-Url: http://hostap.epitest.fi/gitweb/gitweb.cgi?p=hostap.git;a=commitdiff_plain;h=23e072374ea500002b8beec5d0e87f9fc6a7609c;hp=2064c2f98515016c376f3b69bfe161c85639e764 Don't post scan results when initial scan is emtpy When the initial scan is made, just the cached results from the driver are used. If this is empty, it's useless to post the results since another scan is being scheduled immediately. This just causes extra processing from listeners for no gain. --- diff --git a/wpa_supplicant/events.c b/wpa_supplicant/events.c index 0f9b338..04e3152 100644 --- a/wpa_supplicant/events.c +++ b/wpa_supplicant/events.c @@ -551,9 +551,18 @@ static void wpa_supplicant_event_scan_results(struct wpa_supplicant *wpa_s) goto req_scan; } - wpa_msg(wpa_s, MSG_INFO, WPA_EVENT_SCAN_RESULTS); - - wpa_supplicant_dbus_notify_scan_results(wpa_s); + /* + * Don't post the results if this was the initial cached + * and there were no results. + */ + if (wpa_s->scan_res_tried == 1 && wpa_s->conf->ap_scan == 1 && + wpa_s->scan_res->num == 0) { + wpa_msg(wpa_s, MSG_DEBUG, "Cached scan results are " + "empty - not posting"); + } else { + wpa_msg(wpa_s, MSG_INFO, WPA_EVENT_SCAN_RESULTS); + wpa_supplicant_dbus_notify_scan_results(wpa_s); + } if (wpa_s->conf->ap_scan == 2 || wpa_s->disconnected) return;
