If transition to a new state could take 607c478bd9Sstevel@tonic-gate * some time, then before we effect the transition we set 617c478bd9Sstevel@tonic-gate * restarter_inst_t->ri_i.i_next_state to the target state, and afterwards we 627c478bd9Sstevel@tonic-gate * rotate i_next_state to i_state and set i_next_state to 637c478bd9Sstevel@tonic-gate * RESTARTER_STATE_NONE. So usually i_next_state is _NONE when ri_lock is not 647c478bd9Sstevel@tonic-gate * held. The exception is when we launch methods, which are done with 657c478bd9Sstevel@tonic-gate * a separate thread. To keep any other threads from grabbing ri_lock before 667c478bd9Sstevel@tonic-gate * method_thread() does, we set ri_method_thread to the thread id of the 677c478bd9Sstevel@tonic-gate * method thread, and when it is nonzero any thread with a different thread id 687c478bd9Sstevel@tonic-gate * waits on ri_method_cv. 697c478bd9Sstevel@tonic-gate * 707c478bd9Sstevel@tonic-gate * Method execution is serialized by blocking on ri_method_cv in 717c478bd9Sstevel@tonic-gate * inst_lookup_by_id() and waiting for a 0 value of ri_method_thread. This 727c478bd9Sstevel@tonic-gate * also prevents the instance structure from being deleted until all 737c478bd9Sstevel@tonic-gate * outstanding operations such as method_thread() have finished. 747c478bd9Sstevel@tonic-gate * 757c478bd9Sstevel@tonic-gate * Lock ordering: 767c478bd9Sstevel@tonic-gate * 777c478bd9Sstevel@tonic-gate * dgraph_lock [can be held when taking:] 787c478bd9Sstevel@tonic-gate * utmpx_lock 797c478bd9Sstevel@tonic-gate * dictionary->dict_lock 807c478bd9Sstevel@tonic-gate * st->st_load_lock 817c478bd9Sstevel@tonic-gate * wait_info_lock 827c478bd9Sstevel@tonic-gate * ru->restarter_update_lock 837c478bd9Sstevel@tonic-gate * restarter_queue->rpeq_lock 847c478bd9Sstevel@tonic-gate * instance_list.ril_lock 857c478bd9Sstevel@tonic-gate * inst->ri_lock 867c478bd9Sstevel@tonic-gate * st->st_configd_live_lock 877c478bd9Sstevel@tonic-gate * 887c478bd9Sstevel@tonic-gate * instance_list.ril_lock 897c478bd9Sstevel@tonic-gate * graph_queue->gpeq_lock 907c478bd9Sstevel@tonic-gate * gu->gu_lock 917c478bd9Sstevel@tonic-gate * st->st_configd_live_lock 927c478bd9Sstevel@tonic-gate * dictionary->dict_lock 937c478bd9Sstevel@tonic-gate * inst->ri_lock 947c478bd9Sstevel@tonic-gate * graph_queue->gpeq_lock 957c478bd9Sstevel@tonic-gate * gu->gu_lock 967c478bd9Sstevel@tonic-gate * tu->tu_lock 977c478bd9Sstevel@tonic-gate * tq->tq_lock 987c478bd9Sstevel@tonic-gate * inst->ri_queue_lock 997c478bd9Sstevel@tonic-gate * wait_info_lock 1007c478bd9Sstevel@tonic-gate * bp->cb_lock 1017c478bd9Sstevel@tonic-gate * utmpx_lock 1027c478bd9Sstevel@tonic-gate * 1037c478bd9Sstevel@tonic-gate * single_user_thread_lock 1047c478bd9Sstevel@tonic-gate * wait_info_lock 1057c478bd9Sstevel@tonic-gate * utmpx_lock 1067c478bd9Sstevel@tonic-gate * 1077c478bd9Sstevel@tonic-gate * gu_freeze_lock 1087c478bd9Sstevel@tonic-gate * 1097c478bd9Sstevel@tonic-gate * logbuf_mutex nests inside pretty much everything. 1107c478bd9Sstevel@tonic-gate */ 1117c478bd9Sstevel@tonic-gate 1127c478bd9Sstevel@tonic-gate #include <sys/contract/process.h> 1137c478bd9Sstevel@tonic-gate #include <sys/ctfs.h> 1147c478bd9Sstevel@tonic-gate #include <sys/stat.h> 1157c478bd9Sstevel@tonic-gate #include <sys/time.h> 1167c478bd9Sstevel@tonic-gate #include <sys/types.h> 1177c478bd9Sstevel@tonic-gate #include <sys/uio.h> 1187c478bd9Sstevel@tonic-gate #include <sys/wait.h> 1197c478bd9Sstevel@tonic-gate #include <assert.h> 1207c478bd9Sstevel@tonic-gate #include <errno.h> 1217c478bd9Sstevel@tonic-gate #include <fcntl.h> 1227c478bd9Sstevel@tonic-gate #include <libcontract.h> 1237c478bd9Sstevel@tonic-gate #include <libcontract_priv.h> 1247c478bd9Sstevel@tonic-gate #include <libintl.h> 1257c478bd9Sstevel@tonic-gate #include <librestart.h> 1267c478bd9Sstevel@tonic-gate #include <librestart_priv.h> 1277c478bd9Sstevel@tonic-gate #include <libuutil.h> 1287c478bd9Sstevel@tonic-gate #include <limits.h> 1297c478bd9Sstevel@tonic-gate #include <poll.h> 1307c478bd9Sstevel@tonic-gate #include <port.h> 1317c478bd9Sstevel@tonic-gate #include <pthread.h> 1327c478bd9Sstevel@tonic-gate #include <stdarg.h> 1337c478bd9Sstevel@tonic-gate #include <stdio.h> 1347c478bd9Sstevel@tonic-gate #include <strings.h> 1357c478bd9Sstevel@tonic-gate #include <unistd.h> 1367c478bd9Sstevel@tonic-gate 1377c478bd9Sstevel@tonic-gate #include "startd.h" 1387c478bd9Sstevel@tonic-gate #include "protocol.h" 1397c478bd9Sstevel@tonic-gate 1407c478bd9Sstevel@tonic-gate static uu_list_pool_t *restarter_instance_pool;
