Otherwise, a substring will be treated as equal. This bug might cause ssids to get scanned as public ssids (rather than hidden), resulting in broadcast probe request (instead of ssid-specific ones) Signed-off-by: Eliad Peller Signed-off-by: Luciano Coelho --- diff --git a/drivers/net/wireless/ti/wlcore/scan.c b/drivers/net/wireless/ti/wlcore/scan.c index 94668d8ba14e..e1dbe812615f 100644 --- a/drivers/net/wireless/ti/wlcore/scan.c +++ b/drivers/net/wireless/ti/wlcore/scan.c @@ -605,7 +605,9 @@ wl12xx_scan_sched_scan_ssid_list(struct wl1271 *wl, continue; for (j = 0; j < cmd->n_ssids; j++) - if (!memcmp(req->ssids[i].ssid, + if ((req->ssids[i].ssid_len == + req->ssids[j].ssid_len) && + !memcmp(req->ssids[i].ssid, cmd->ssids[j].ssid, req->ssids[i].ssid_len)) { cmd->ssids[j].type =
