In this case the loop was attempting to match SSIDs in the filter list to this empty entry and marking them as HIDDEN (sending probe request) by mistake Signed-off-by: Eyal Shapira Signed-off-by: Luciano Coelho --- diff --git a/drivers/net/wireless/wl12xx/scan.c b/drivers/net/wireless/wl12xx/scan.c index 330d6788a916..8599dab1fe2a 100644 --- a/drivers/net/wireless/wl12xx/scan.c +++ b/drivers/net/wireless/wl12xx/scan.c @@ -572,6 +572,9 @@ wl12xx_scan_sched_scan_ssid_list(struct wl1271 *wl, * so they're used in probe requests. */ for (i = 0; i < req->n_ssids; i++) { + if (!req->ssids[i].ssid_len) + continue; + for (j = 0; j < cmd->n_ssids; j++) if (!memcmp(req->ssids[i].ssid, cmd->ssids[j].ssid,
