65  * The comments below would help in understanding what is being attempted
66  * in the server.
67  *
68  * The server can be started either by inetd or by the client directly.
69  * Normally the server is started by inetd when the client invokes the
70  * appropriate libsmedia library call(smedia_get_handle).
71  * However since the inetd runs only at init level 2 and above a mechanism
72  * is provided for the server to be started if an attempt is made to use
73  * the libsmedia calls in maintenence mode(init level 1).
74  * The main() routine determines how the server was invoked and takes
75  * the necessary action.
76  * When started by inetd it registers itself as an RPC program.
77  * The server also implements a mechanism by which it removes itself
78  * after a period of inactivity. The period of inactivity is specified
79  * by SVC_CLOSEDOWN which is set at 180 secs.
80  * The logic of detecting inactivity is as follows:
81  *
82  * Two variables svcstate and svccount are used to determine if the server
83  * is IDLE.
84  * The svcstate is set to 1(_SERVED) when ever the server does any operation
85  * on behalf of the client.
86  * The svccount indicates the number of active clients who have established
87  * a connection with the server. A connection is established when the
88  * libsmedia call smedia_get_handle() succeeds.
89  * The connection is broken when the client calls smedia_free_handle() OR
90  * exits.
91  * A thread called closedown is started up when server is started.
92  * This thread runs periodically and monitors both svcstate and svccount.
93  * If svcstate is IDLE and svccount is 0 then server exits.
94  * The svcstate is set to IDLE by the closedown thread. It is set to _SERVED
95  * by server. It is possible for the state to be _SERVED and the svccount
96  * to be 0. The server could be kept busy by client calls of smedia_get_handle
97  * that do not succeed. This is the reason for using both svcstate and svccount
98  * to determine the true server state.
99  *
100  * The communication between client and server is thru door calls.
101  * Below are the door descriptors available to communicate to the server.
102  *
103  * main_door_descriptor:
104  * ---------------------
105  * 	This is a predefined descriptor used by client to establish a
106  * connection with the server. This descriptor is available to the client
107  * as /var/adm/smedia_svc
108  * The client uses the main_door_descriptor to obtain a dedicated
109  * client_door_descriptor for itself. The smedia_get_handle call communicates
110  * to the server using the main_door_descriptor and obtains the
111  * client_door_descriptor which is stored in the handle structure.
112  * All other libsmedia calls use the client_door_descriptor to communicate
113  * with the server.
114  *
115  * client_door_descriptor:
116  * -----------------------
117  *	This is the door descriptor that is used by the clients to
118  * request server to perform the necessary tasks. This door descriptor is
119  * available only to the client for whom it was created.
120  *
121  * death_door_descriptor:
122  * ----------------------
123  * 	The sole function of this descriptor HAD been to inform the server of
124  * the untimely death of the client. This descriptor is no longer used, though
125  * it is still created, as libsmedia expects to use it.  This descriptor's
126  * service procedure had used pthread cancellation(5) to terminate the thread of
127  * the associated client_door_descriptor.  The client_door_descriptor now
128  * handles the scenarios where a door_call/client are aborted/terminated.
129  *
130  * main_servproc()
131  * -------------
132  *	This is the routine associated with the main_door_descriptor.
133  * This is the routine that handles the smedia_get_handle() call
134  * of the client. If the door call to this routine succeeds it creates a
135  * client_door_descriptor that is used by the client in subsequent library
136  * calls.
137  * This client_door_descriptor is passed to the client thru the door_return
138  * call. This client_door_descriptor cannot be used by any other process other
139  * than the client process that obtained it.
140  * In addition to the client_door_descriptor a death_door_descriptor is also
141  * created by the main server and passed on to the client. The client does not
142  * use the death_door_descriptor.
143  *
144  * client_servproc()
145  * ---------------
146  *	This is the routine that handles the libsmedia calls of the
147  * client. In the current implementation the server takes control of the
148  * number of threads that handle the door calls. This is done by creating the
149  * door descriptor as DOOR_PRIVATE.
150  * The server runs only one thread per handle. This makes the implementation
151  * simple as we do not have to use mutex to make the code MT safe.
152  * The server thread has a data structure door_data_t associated with it.
153  *
154  * door_data_t
155  * -----------
156  * This is the data structure that is created by the main_servproc when it
157  * creates the client_door_descriptor. The door mechanism has a way to associate
158  * a cookie with the door descriptor. door_data_t is the cookie for the
159  * client_door_descriptor. This cookie is passed to the server function that
160  * handles the client_door_descriptor calls. In our case it is the
161  * client_servproc routine.
162  * The key elements of the door_data_t are the following:
163  *
164  *	dd_fd		file descriptor for the device.
165  *	dd_buf		The shared memory buffer between client-server.
166  *	dd_thread	The thread that handles the door_calls.
167  *
168  * signal handling:
169  * ----------------
170  *		The main purpose of trapping the signals is to exit gracefully
171  * from the server after recording the appropriate message in the syslog.
172  * This will help the administrator to determine the cause of failure of the
173  * server by examining the log file.
174  *
175  * cleanup()
176  * ---------
177  *	This routine frees up all the resources allocated for the client.
178  * Resources include the file descriptor, shared memory, threads.
179  *
180  * shared memory
181  * -------------
182  *	In order to reduce the overheads of moving large amounts of data
183  * during raw read/write operations, the server uses the mmapped data of
184  * client. The smedia_raw_read, smedia_raw_write library calls mmap the
185  * memory and pass on the file descriptor that maps the memory to the server.
186  * The server subsequently uses this mmapped memory during the IO.
187  * If the mmapped memory changes in size, the server is informed and it
188  * remaps the memory to the changed size.

1481  * door_call(3c)'s.
1482  *
1483  * This function is called synchronously as part of door_create(3c).
1484  * Note that door_create(), however, is not synchronous; it can return
1485  * with the created door file descriptor before any associated
1486  * thread has been created.  As a result, synchronization is needed
1487  * between door_create() caller and the created pthread.  This is
1488  * needed both when each activity succeeds or when either activity
1489  * fails.
1490  *
1491  * Specifically, this function ensures that each "connection"
1492  * with the client creates only one thread in the per-door,
1493  * private thread pool.  This function locks dd_threadlock and
1494  * then calls pthread_create().  If that succeeds, dd_thread
1495  * is assigned the thread id, and dd_threadlock is unlocked.
1496  * Any per-connection door_create that causes control to flow
1497  * to this function will eventually find that dd_thread is
1498  * non-zero, and control will exit this function.
1499  *
1500  * In the current implementation, the door_create for the Client Door
1501  * is called first, and the Death Door is door_create'd second.
1502  * As a result, the following function can safely make the static
1503  * assumption that the first door (within a connection) is the
1504  * Client Door.  A connection's Client Door and Death Door share
1505  * the same thread as well as the same door_data_t instance.
