The period of inactivity is specified * by SVC_CLOSEDOWN which is set at 180 secs. * The logic of detecting inactivity is as follows: * * Two variables svcstate and svccount are used to determine if the server * is IDLE. * The svcstate is set to 1(_SERVED) when ever the server does any operation * on behalf of the client. * The svccount indicates the number of active clients who have established * a connection with the server. A connection is established when the * libsmedia call smedia_get_handle() succeeds. * The connection is broken when the client calls smedia_free_handle() OR * exits. * A thread called closedown is started up when server is started. * This thread runs periodically and monitors both svcstate and svccount. * If svcstate is IDLE and svccount is 0 then server exits. * The svcstate is set to IDLE by the closedown thread. It is set to _SERVED * by server. It is possible for the state to be _SERVED and the svccount * to be 0. The server could be kept busy by client calls of smedia_get_handle * that do not succeed. This is the reason for using both svcstate and svccount * to determine the true server state. * * The communication between client and server is thru door calls. * Below are the door descriptors available to communicate to the server. * * main_door_descriptor: * --------------------- * This is a predefined descriptor used by client to establish a * connection with the server. This descriptor is available to the client * as /var/adm/smedia_svc * The client uses the main door_descriptor to obtain a dedicated * client_door_descriptor for itself. The smedia_get_handle call communicates * to the server using the main_door_descriptor and obtains the * client_door_descriptor which is stored in the handle structure. * All other libsmedia calls use the client_door_descriptor to communicate * with the server. * * client_door_descriptor: * ----------------------- * This is the door descriptor that is used by the clients to * request server to perform the necessary tasks. This door descriptor is * available only to the client for whom it was created. * * death_door_descriptor: * ---------------------- * The sole function of this door descriptor is to inform the server of * the untimely death of the client. This helps the server to do the necessary * cleanups. * * main_server() * ------------- * This is the routine associated with the main_door_descriptor. * This is the routine that handles the smedia_get_handle() call * of the client. If the door call to this routine succeeds it creates a * client_door_descriptor that is used by the client in subsequent library * calls. * This client_door_descriptor is passed to the client thru the door_return * call. This client_door_descriptor cannot be used by any other process other * than the client process that obtained it. * In addition to the client_door_descriptor a death_door_descriptor is also * created by the main server and passed on to the client. The client does not * use the death_door_descriptor at all. It is there to inform the server in * case the client program were to exit without calling smedia_free_handle(). * * client_server() * --------------- * This is the routine that handles the libsmedia calls of the * client. In the current implementation the server takes control of the * number of threads that handle the door calls. This is done by creating the * door descriptor as DOOR_PRIVATE. * The server runs only one thread per handle. This makes the implementation * simple as we do not have to use mutex to make the code MT safe. * The client_server thread has a data structure door_data_t associated with it. * * door_data_t * ----------- * This is the data structure that is created by the main_server when it * creates the client_door_descriptor. The door mechanism has a way to associate * a cookie with the door descriptor. door_data_t is the cookie for the * client-door_descriptor. This cookie is passed to the server function that * handles the clinet_door_descriptor calls. In our case it is the client_server * routine. * The key elements of the door_data_t are the following: * * dd_fd file descriptor for the device. * dd_buf The shared memory buffer between client-server. * dd_thread The thread that handles the door_calls. * * signal handling: * ---------------- * The main purpose of trapping the signals is to exit gracefully * from the server after recording the appropriate message in the syslog. * This will help the administrator to determine the cause of failure of the * server by examining the log file. * * cleanup() * --------- * This routine frees up all the resources allocated for the client. * Resources inlcude the file descriptor, shared memory, threads. * * shared memory * ------------- * In order to reduce the overheads of moving large amounts of data * during raw read/write operations, the server uses the mmapped data of * client. The smedia_raw_read, smedia_raw_write library calls mmap the * memory and pass on the file descriptor that maps the memory to the server. * The server subsequently uses this mmapped memory during the IO. * If the mmapped memory changes in size, the server is informed and it * remaps the memory to the changed size. */ #ifdef DEBUG #define DEFAULT_VERBOSE 1 #define DEFAULT_DEBUG 1 #else #define DEFAULT_VERBOSE 0 #define DEFAULT_DEBUG 0 #endif #define N_BADSIGS (sizeof (badsigs)/sizeof (badsigs[0])) #define MD_LEN 30 #define MAXUGNAME 10 #define SVC_CLOSEDOWN 180 /* * We will NOT be permitting the following USCI cmd options. * * RESET of target * RESET of Bus. * Tagged commands to device * Explicitly setting SYNC/ASYNC mode of operations. * POLLED MODE of operation. * Explicitly setting NO DISCONNECT features. * use of RESERVED flags. */ #define FORBIDDEN_FLAGS (USCSI_RESET | USCSI_RESET_ALL | USCSI_RENEGOT \ | USCSI_ASYNC | USCSI_SYNC | USCSI_NOINTR | \ USCSI_NOTAG | USCSI_NOPARITY | USCSI_NODISCON \ | USCSI_RESERVED) /* States a server can be in wrt request */ #define _IDLE 0 #define _SERVED 1 static char *prog_name;
