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

1480  * door_call(3c)'s.
1481  *
1482  * This function is called synchronously as part of door_create(3c).
1483  * Note that door_create(), however, is not synchronous; it can return
1484  * with the created door file descriptor before any associated
1485  * thread has been created.  As a result, synchronization is needed
1486  * between door_create() caller and the created pthread.  This is
1487  * needed both when each activity succeeds or when either activity
1488  * fails.
1489  *
1490  * Specifically, this function ensures that each "connection"
1491  * with the client creates only one thread in the per-door,
1492  * private thread pool.  This function locks dd_threadlock and
1493  * then calls pthread_create().  If that succeeds, dd_thread
1494  * is assigned the thread id, and dd_threadlock is unlocked.
1495  * Any per-connection door_create that causes control to flow
1496  * to this function will eventually find that dd_thread is
1497  * non-zero, and control will exit this function.
1498  *
1499  * In the current implementation, the door_create for the Client Door
1500  * is called first, and the Death Door is door_create'd second.
1501  * As a result, the following function can safely make the static
1502  * assumption that the first door (within a connection) is the
1503  * Client Door.  A connection's Client Door and Death Door share
1504  * the same thread as well as the same door_data_t instance.
