-		     A Sample Authorization Protocol for X
-
-
-Overview
-
-The following note describes a very simple mechanism for providing individual
-access to an X Window System display.  It uses existing core protocol and
-library hooks for specifying authorization data in the connection setup block
-to restrict use of the display to only those clients that show that they
-know a server-specific key called a "magic cookie".  This mechanism is *not*
-being proposed as an addition to the Xlib standard; among other reasons, a
-protocol extension is needed to support more flexible mechanisms.  We have
-implemented this mechanism already; if you have comments, please send them
-to us.
-
-This scheme involves changes to the following parts of the sample release:
-
-    o  xdm
-	-  generate random magic cookie and store in protected file
-	-  pass name of magic cookie file to server
-	-  when user logs in, add magic cookie to user's auth file
-	-  when user logs out, generate a new cookie for server
-
-    o  server
-	-  a new command line option to specify cookie file
-	-  check client authorization data against magic cookie
-	-  read in cookie whenever the server resets
-	-  do not add local machine to host list if magic cookie given
-
-    o  Xlib
-	-  read in authorization data from file
-	-  find data for appropriate server
-	-  send authorization data if found
-
-    o  xauth [new program to manage user auth file]
-	-  add entries to user's auth file
-	-  remove entries from user's auth file
-
-This mechanism assumes that the superuser and the transport layer between 
-the client and the server is secure.  Organizations that desire stricter
-security are encouraged to look at systems such as Kerberos (at Project
-Athena).
-
-
-Description
-
-The sample implementation will use the xdm Display Manager to set up and
-control the server's authorization file.  Sites that do not run xdm will
-need to build their own mechanisms.  
-
-Xdm uses a random key (seeded by the system time and check sum of /dev/kmem)
-to generate a unique sequence of characters at 16 bytes long.  This sequence
-will be written to a file which is made readable only by the server.  The
-server will then be started with a command line option instructing it to use
-the contents of the file as the magic cookie for connections that include
-authorization data.  This will also disable the server from adding the local
-machine's address to the initial host list.  Note that the actual cookie must
-not be stored on the command line or in an environment variable, to prevent
-it from being publicly obtainable by the "ps" command.
-
-If a client presents an authorization name of "MIT-MAGIC-COOKIE-1" and
-authorization data that matches the magic cookie, that client is allowed
-access.  If the name or data does not match and the host list is empty,
-that client will be denied access.  Otherwise, the existing host-based access
-control will be used.  Since any client that is making a connection from a
-machine on the host list will be granted access even if their authorization
-data is incorrect, sites are strongly urged not to set up any default hosts
-using the /etc/X*.hosts files.  Granting access to other machines should be
-done by the user's session manager instead.
-
-Assuming the server is configured with an empty host list, the existence of the
-cookie is sufficient to ensure there will be no unauthorized access to the
-display.  However, xdm will (continue to) work to minimize the chances of
-spoofing on servers that do not support this authorization mechanism.  This
-will be done by grabbing the server and the keyboard after opening the display.
-This action will be surrounded by a timer which will kill the server if the
-grabs cannot be done within several seconds.  [This level of security is now
-implemented in patches already sent out.]
-
-After the user logs in, xdm will add authorization entries for each of the
-server machine's network addresses to the user's authorization file (the format
-of which is described below).  This file will usually be named .Xauthority in
-the users's home directory; will be owned by the user (as specified by the
-pw_uid and pw_gid fields in the user's password entry), and will be accessible
-only to the user (no group access).  This file will contain authorization data
-for all of the displays opened by the user.
-
-When the session terminates, xdm will generate and store a new magic cookie
-for the server.  Then, xdm will shutdown its own connection and send a
-SIGHUP to the server process, which should cause the server to reset.  The
-server will then read in the new magic cookie.
-
-To support accesses (both read and write) from multiple machines (for use in
-environments that use distributed file systems), file locking is done using
-hard links.  This is done by creat'ing (sic) a lock file and then linking it
-to another name in the same directory.  If the link-target already exists,
-the link will fail, indicating failure to obtain the lock.  Linking is used
-instead of just creating the file read-only since link will fail even for
-the superuser.
-
-Problems and Solutions
-
-There are a few problems with .Xauthority as described.  If no home directory
-exists, or if xdm cannot create a file there (disk full), xdm stores the
-cookie in a file in a resource-specified back-up directory, and sets an
-environment variable in the user's session (called XAUTHORITY) naming this
-file.  There is also the problem that the locking attempts will need to be
-timed out, due to a leftover lock.  Xdm, again, creates a file and set an
-environment variable.  Finally, the back-up directory might be full.  Xdm,
-as a last resort, provides a function key binding that allows a user to log
-in without having the authorization data stored, and with host-based access
-control disabled.
-
-Xlib
-
-XOpenDisplay in Xlib was enhanced to allow specification of authorization
-information.  As implied above, Xlib looks for the data in the
-.Xauthority file of the home directory, or in the file pointed at by the
-XAUTHORITY environment variable instead if that is defined.  This required
-no programmatic interface change to Xlib.  In addition, a new Xlib routine
-is provided to explicitly specify authorization.
-
-	XSetAuthorization(name, namelen, data, datalen)
-		int namelen, datalen;
-		char *name, *data;
-
-There are three types of input:
-
-	name NULL, data don't care	- use default authorization mechanism.
-	name non-NULL, data NULL	- use the named authorization; get
-					  data from that mechanism's default.
-	name non-NULL, data non-NULL	- use the given authorization and data.
-					
-This interface is used by xdm and might also be used by any other
-applications that wish to explicitly set the authorization information.
-
-Authorization File
-
-The .Xauthority file is a binary file consisting of a sequence of entries
-in the following format:
-
-	2 bytes		Family value (second byte is as in protocol HOST)
-	2 bytes		address length (always MSB first)
-	A bytes		host address (as in protocol HOST)
-	2 bytes		display "number" length (always MSB first)
-	S bytes		display "number" string
-	2 bytes		name length (always MSB first)
-	N bytes		authorization name string
-	2 bytes		data length (always MSB first)
-	D bytes		authorization data string
-
-The format is binary for easy processing, since authorization information
-usually consists of arbitrary data.  Host addresses are used instead of
-names to eliminate potentially time-consuming name resolutions in
-XOpenDisplay.  Programs, such as xdm, that initialize the user's
-authorization file will have to do the same work as the server in finding
-addresses for all network interfaces.  If more than one entry matches the
-desired address, the entry that is chosen is implementation-dependent.  In
-our implementation, it is always the first in the file.
-
-The Family is specified in two bytes to allow out-of-band values
-(i.e. values not in the Protocol) to be used.  In particular,
-two new values "FamilyLocal" and "FamilyWild" are defined.  FamilyLocal
-refers to any connections using a non-network method of connetion from the
-local machine (Unix domain sockets, shared memory, loopback serial line).
-In this case the host address is specified by the data returned from
-gethostname() and better be unique in a collection of machines
-which share NFS directories.  FamilyWild is currently used only
-by xdm to communicate authorization data to the server.  It matches
-any family/host address pair.
-
-For FamilyInternet, the host address is the 4 byte internet address, for
-FamilyDecnet, the host address is the byte decnet address, for FamilyChaos
-the address is also two bytes.
-
-The Display Number is the ascii representation of the display number
-portion of the display name.  It is in ascii to allow future expansion
-to PseudoRoots or anything else that might happen.
-
-A utility called "xauth" will be provided for editing and viewing the
-contents of authorization files.  Note that the user's authorization file is
-not the same as the server's magic cookie file.

- * XauKrb5Encode

- * follows:
- *   length count of the realm name
- *   realm
- *   component count
- *   length of component
- *   actual principal component
- *   etc....
- *
- * Note that this function allocates a hunk of memory, which must be
- * freed to avoid nasty memory leak type things.  All counts are
- * byte-swapped if needed. (except for the total length returned)
- *
- * nevermind.... stuffing the encoded packet in net byte order just to
- * always do the right thing.  Don't have to frob with alignment that way.
