/*
 * Flags field of the SMB header. The names in parenthesis represent
 * alternative names for the flags.
 *
 * SMB_FLAGS_LOCK_AND_READ_OK     If the server supports LockAndRead and
 * (SMB_FLAGS_LOCKS_SUBDIALECT)   WriteAndUnlock, it sets this bit in the
 *                                Negotiate response.
 *
 * SMB_FLAGS_SEND_NO_ACK          When on, the client guarantees that there
 * (SMB_FLAGS_RCV_BUF_POSTED)     is a receive buffer posted such that a
 *                                "Send-No-Ack" can be used by the server
 *                                to respond to the client's request.
 *
 * SMB_FLAGS_CASE_INSENSITIVE     This is part of the Flags field of every
 *                                SMB header. If this bit is set, then all
 *                                pathnames in the SMB should be treated as
 *                                case-insensitive. Otherwise pathnames are
 *                                case-sensitive.
 *
 * SMB_FLAGS_CANONICALIZED_PATHS  When on in SessionSetupX, this indicates
 *                                that all paths sent to the server are
 *                                already in OS/2 canonicalized format.
 *
 * OS/2 canonical format means that file/directory names are in upper case,
 * are valid characters, . and .. have been removed and single backslashes
 * are used as separators.
 *
 * SMB_FLAGS_OPLOCK               When set in an open file request SMBs
 *                                (Open, Create, OpenX, etc.) this bit
 *                                indicates a request for an oplock on the
 *                                file. When set in the response, this bit
 *                                indicates that the oplock was granted.
 *
 * SMB_FLAGS_OPLOCK_NOTIFY_ANY    When on, this bit indicates that the server
 *                                should notify the client on any request
 *                                that could cause the file to be changed.
 *                                If not set, the server only notifies the
 *                                client on other open requests on the file.
 *                                This bit is only relevant when
 *                                SMB_FLAGS_OPLOCK is set.
 *
 * SMB_FLAGS_SERVER_TO_REDIR      This bit indicates that the SMB is being
 * (SMB_FLAGS_REPLY)              sent from server to (client) redirector.

 * CIFS protocol; they are messages in some authentication protocol that
 * has been agreed upon by client and server by some out of band mechanism,
 * for which CIFS merely functions as a transport. When
 * CAP_EXTENDED_SECURITY is negotiated, the server includes a first
 * security blob in its response; subsequent security blobs are exchanged
 * in SMB_COM_SESSION_SETUP_ANDX requests and responses until the
 * authentication protocol terminates.
