-Subject: [PATCH 1/5] WPS: Reject a Credential with invalid passphrase
-
-WPA/WPA2-Personal passphrase is not allowed to include control
-characters. Reject a Credential received from a WPS Registrar both as
-STA (Credential) and AP (AP Settings) if the credential is for WPAPSK or
-WPA2PSK authentication type and includes an invalid passphrase.
-
-This fixes an issue where hostapd or wpa_supplicant could have updated
-the configuration file PSK/passphrase parameter with arbitrary data from
-an external device (Registrar) that may not be fully trusted. Should
-such data include a newline character, the resulting configuration file
-could become invalid and fail to be parsed.
