    [CIFS] Fix plaintext authentication · bcc55c66
    Steve French authored
    The last eight bytes of the password field were not cleared when doing lanman plaintext password authentication. This patch fixes that.
    
    I tested it with Samba by setting password
    encryption to no in the server's smb.conf.  Other servers also can be
    configured to force plaintext authentication.    Note that plaintexti
    authentication requires setting /proc/fs/cifs/SecurityFlags to 0x30030
    on the client (enabling both LANMAN and also plaintext password support).
    Also note that LANMAN support (and thus plaintext password support) requires
    CONFIG_CIFS_WEAK_PW_HASH to be enabled in menuconfig.
