The graph engine is based in graph.c and 33*0Sstevel@tonic-gate * maintains the service dependency graph based on the information in the 34*0Sstevel@tonic-gate * repository. For each service it also tracks the current state and the 35*0Sstevel@tonic-gate * restarter responsible for the service. Based on the graph, events from the 36*0Sstevel@tonic-gate * repository (mostly administrative requests from svcadm), and messages from 37*0Sstevel@tonic-gate * the restarters, the graph engine makes decisions about how the services 38*0Sstevel@tonic-gate * should be manipulated and sends commands to the appropriate restarters. 39*0Sstevel@tonic-gate * Communication between the graph engine and the restarters is embodied in 40*0Sstevel@tonic-gate * protocol.c. 41*0Sstevel@tonic-gate * 42*0Sstevel@tonic-gate * The second half of svc.startd is the restarter for services managed by 43*0Sstevel@tonic-gate * svc.startd and is primarily contained in restarter.c. It responds to graph 44*0Sstevel@tonic-gate * engine commands by executing methods, updating the repository, and sending 45*0Sstevel@tonic-gate * feedback (mostly state updates) to the graph engine. 46*0Sstevel@tonic-gate * 47*0Sstevel@tonic-gate * Error handling 48*0Sstevel@tonic-gate * 49*0Sstevel@tonic-gate * In general, when svc.startd runs out of memory it reattempts a few times, 50*0Sstevel@tonic-gate * sleeping inbetween, before giving up and exiting (see startd_alloc_retry()). 51*0Sstevel@tonic-gate * When a repository connection is broken (libscf calls fail with 52*0Sstevel@tonic-gate * SCF_ERROR_CONNECTION_BROKEN, librestart and internal functions return 53*0Sstevel@tonic-gate * ECONNABORTED), svc.startd calls libscf_rebind_handle(), which coordinates 54*0Sstevel@tonic-gate * with the svc.configd-restarting thread, fork_configd_thread(), via 55*0Sstevel@tonic-gate * st->st_configd_live_cv, and rebinds the repository handle. Doing so resets 56*0Sstevel@tonic-gate * all libscf state associated with that handle, so functions which do this 57*0Sstevel@tonic-gate * should communicate the event to their callers (usually by returning 58*0Sstevel@tonic-gate * ECONNRESET) so they may reset their state appropriately. 59*0Sstevel@tonic-gate */ 60*0Sstevel@tonic-gate 61*0Sstevel@tonic-gate #include <stdio.h> 62*0Sstevel@tonic-gate #include <sys/mnttab.h> /* uses FILE * without including stdio.h */ 63*0Sstevel@tonic-gate #include <alloca.h> 64*0Sstevel@tonic-gate #include <sys/mount.h> 65*0Sstevel@tonic-gate #include <sys/stat.h> 66*0Sstevel@tonic-gate #include <sys/types.h> 67*0Sstevel@tonic-gate #include <sys/wait.h> 68*0Sstevel@tonic-gate #include <assert.h> 69*0Sstevel@tonic-gate #include <errno.h> 70*0Sstevel@tonic-gate #include <fcntl.h> 71*0Sstevel@tonic-gate #include <ftw.h> 72*0Sstevel@tonic-gate #include <libintl.h> 73*0Sstevel@tonic-gate #include <libscf.h> 74*0Sstevel@tonic-gate #include <libscf_priv.h> 75*0Sstevel@tonic-gate #include <libuutil.h> 76*0Sstevel@tonic-gate #include <locale.h> 77*0Sstevel@tonic-gate #include <poll.h> 78*0Sstevel@tonic-gate #include <pthread.h> 79*0Sstevel@tonic-gate #include <signal.h> 80*0Sstevel@tonic-gate #include <stdarg.h> 81*0Sstevel@tonic-gate #include <stdlib.h> 82*0Sstevel@tonic-gate #include <string.h> 83*0Sstevel@tonic-gate #include <strings.h> 84*0Sstevel@tonic-gate #include <unistd.h> 85*0Sstevel@tonic-gate 86*0Sstevel@tonic-gate #include "startd.h" 87*0Sstevel@tonic-gate #include "protocol.h" 88*0Sstevel@tonic-gate 89*0Sstevel@tonic-gate ssize_t max_scf_name_size; 90*0Sstevel@tonic-gate ssize_t max_scf_fmri_size; 91*0Sstevel@tonic-gate ssize_t max_scf_value_size; 92*0Sstevel@tonic-gate 93*0Sstevel@tonic-gate mode_t fmask; 94*0Sstevel@tonic-gate mode_t dmask; 95*0Sstevel@tonic-gate 96*0Sstevel@tonic-gate graph_update_t *gu; 97*0Sstevel@tonic-gate restarter_update_t *ru; 98*0Sstevel@tonic-gate 99*0Sstevel@tonic-gate startd_state_t *st; 100*0Sstevel@tonic-gate 101*0Sstevel@tonic-gate boolean_t booting_to_single_user = B_FALSE; 102*0Sstevel@tonic-gate 103*0Sstevel@tonic-gate const char * const admin_actions[] = { 104*0Sstevel@tonic-gate SCF_PROPERTY_DEGRADED, 105*0Sstevel@tonic-gate SCF_PROPERTY_MAINT_OFF, 106*0Sstevel@tonic-gate SCF_PROPERTY_MAINT_ON, 107*0Sstevel@tonic-gate SCF_PROPERTY_MAINT_ON_IMMEDIATE, 108*0Sstevel@tonic-gate SCF_PROPERTY_REFRESH, 109*0Sstevel@tonic-gate SCF_PROPERTY_RESTART 110*0Sstevel@tonic-gate }; 111*0Sstevel@tonic-gate 112*0Sstevel@tonic-gate const int admin_events[NACTIONS] = { 113*0Sstevel@tonic-gate RESTARTER_EVENT_TYPE_ADMIN_DEGRADED, 114*0Sstevel@tonic-gate RESTARTER_EVENT_TYPE_ADMIN_MAINT_OFF, 115*0Sstevel@tonic-gate RESTARTER_EVENT_TYPE_ADMIN_MAINT_ON, 116*0Sstevel@tonic-gate RESTARTER_EVENT_TYPE_ADMIN_MAINT_ON_IMMEDIATE, 117*0Sstevel@tonic-gate RESTARTER_EVENT_TYPE_ADMIN_REFRESH, 118*0Sstevel@tonic-gate RESTARTER_EVENT_TYPE_ADMIN_RESTART 119*0Sstevel@tonic-gate }; 120*0Sstevel@tonic-gate 121*0Sstevel@tonic-gate const char * const instance_state_str[] = { 122*0Sstevel@tonic-gate "none", 123*0Sstevel@tonic-gate "uninitialized", 124*0Sstevel@tonic-gate "maintenance", 125*0Sstevel@tonic-gate "offline", 126*0Sstevel@tonic-gate "disabled", 127*0Sstevel@tonic-gate "online", 128*0Sstevel@tonic-gate "degraded" 129*0Sstevel@tonic-gate }; 130*0Sstevel@tonic-gate 131*0Sstevel@tonic-gate static int finished = 0; 132*0Sstevel@tonic-gate static int opt_reconfig = 0; 133*0Sstevel@tonic-gate static uint8_t prop_reconfig = 0; 134*0Sstevel@tonic-gate 135*0Sstevel@tonic-gate #define INITIAL_REBIND_ATTEMPTS 5 136*0Sstevel@tonic-gate #define INITIAL_REBIND_DELAY 3 137*0Sstevel@tonic-gate 138*0Sstevel@tonic-gate pthread_mutexattr_t mutex_attrs; 139*0Sstevel@tonic-gate 140*0Sstevel@tonic-gate const char * 141*0Sstevel@tonic-gate _umem_debug_init(void) 142*0Sstevel@tonic-gate { 143*0Sstevel@tonic-gate return ("default,verbose"); /* UMEM_DEBUG setting */ 144*0Sstevel@tonic-gate } 145*0Sstevel@tonic-gate 146*0Sstevel@tonic-gate const char * 147*0Sstevel@tonic-gate _umem_logging_init(void) 148*0Sstevel@tonic-gate { 149*0Sstevel@tonic-gate return ("fail,contents"); /* UMEM_LOGGING setting */ 150*0Sstevel@tonic-gate } 151*0Sstevel@tonic-gate 152*0Sstevel@tonic-gate /* 153*0Sstevel@tonic-gate * startd_alloc_retry() 154*0Sstevel@tonic-gate * Wrapper for allocation functions.
