+Subject: [PATCH] wps: reconfigure credentials on reload
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When new credentials are configured and hostapd is reconfigured using
+SIGHUP (or reload on the ctrl_iface), also update the wps credentials.
+
+Before these changes, when WPS is triggered the registar always serves
+the credentials that were configured when hostapd started.
