[PATCH 1/2] cifs: use CIFS_MAX_DOMAINNAME_LEN when converting the domain name

From: Jerome Marchand
Date: Thu May 26 2016 - 05:52:33 EST


Currently in build_ntlmssp_auth_blob(), when converting the domain
name to UTF16, CIFS_MAX_USERNAME_LEN limit is used. It should be
CIFS_MAX_DOMAINNAME_LEN. This patch fixes this.
