The + former is used when hello is to be sent immediately. + * ospf_nsm.c: ditto + * ospf_packet.c: (ospf_hello) hello-interval is not checked + for mismatch if fast_hello is set. + (ospf_read) Annoying nit, fix "no ospf_interface" to be debug + rather than a warning, as it can be perfectly normal to + receive packets when logical subnets are used. + (ospf_make_hello) Set hello-interval to 0 if fast-hellos are + configured. + * ospf_vty.c: (ospf_auto_cost_reference_bandwidth) annoying + nit, don't vty_out if this command is given, it gets tired + quick. + (show_ip_ospf_interface_sub) Print the hello-interval + according to whether fast-hello is set or not. + Print the extra 5 millisec characters from (ospf_timer_dump) + if fast-hello is configured. + (ospf_vty_dead_interval_set) new function, common to all + forms of dead-interval command, to set dead-interval and + fast-hello correctly. If a dead-interval is given, unset + fast-hello, else if a hello-multiplier is set, set + dead-interval to 1 and fast-hello to given multiplier. + (ip_ospf_dead_interval_addr_cmd) use + ospf_vty_dead_interval_set(). + (ip_ospf_dead_interval_minimal_addr_cmd) ditto. + (no_ip_ospf_dead_interval) Unset fast-hello. + (no_ip_ospf_hello_interval) Bug-fix, unset of hello-interval + should set it to OSPF_HELLO_INTERVAL_DEFAULT, not + OSPF_ROUTER_DEAD_INTERVAL_DEFAULT. + (config_write_interface) Write out fast-hello. + (ospf_config_write) Write a comment about + "auto-cost reference-bandwidth" having to be equal on all + routers. Hopefully just as noticeable as old practice of + writing to vty, but less annoying. + (ospf_vty_if_init) install the two new dead-interval + commands. + * ospfd.h: Add defines for OSPF_ROUTER_DEAD_INTERVAL_MINIMAL + and OSPF_FAST_HELLO_DEFAULT. + 2005-10-18 Paul Jakma <paul.jakma@sun.com> * (general) SPF memory management cleanup and fix for rare diff --git a/ospfd/ospf_dump.c b/ospfd/ospf_dump.c index ac742692..829c00f7 100644 --- a/ospfd/ospf_dump.c +++ b/ospfd/ospf_dump.c @@ -232,31 +232,39 @@ ospf_nbr_state_message (struct ospf_neighbor *nbr, char *buf, size_t size) const char * ospf_timer_dump (struct thread *t, char *buf, size_t size) { - struct timeval now; - unsigned long h, m, s; + struct timeval now, result; + unsigned long h, m, s, ms; if (!t) return "inactive"; - h = m = s = 0; + h = m = s = ms = 0; memset (buf, 0, size); gettimeofday (&now, NULL); - - s = t->u.sands.tv_sec - now.tv_sec; - if (s >= 3600) + + timersub (&t->u.sands, &now, &result); + + ms = result.tv_usec / 1000; + + if (ms >= 1000) + { + result.tv_sec = ms / 1000; + ms =- result.tv_sec * 1000; + } + if (result.tv_sec >= 3600) { - h = s / 3600; - s -= h * 3600; + h = result.tv_sec / 3600; + result.tv_sec -= h * 3600; } - if (s >= 60) + if (result.tv_sec >= 60) { - m = s / 60; - s -= m * 60; + m = result.tv_sec / 60; + result.tv_sec -= m * 60; } - snprintf (buf, size, "%02ld:%02ld:%02ld", h, m, s); + snprintf (buf, size, "%02ld:%02ld:%02ld.%03ld", h, m, result.tv_sec, ms); return buf; } diff --git a/ospfd/ospf_interface.c b/ospfd/ospf_interface.c index fe32268f..d21dea3b 100644 --- a/ospfd/ospf_interface.c +++ b/ospfd/ospf_interface.c @@ -156,7 +156,7 @@ ospf_if_table_lookup (struct interface *ifp, struct prefix *prefix) p.prefixlen = IPV4_MAX_PREFIXLEN; /* route_node_get implicitely locks */ - if (rn = route_node_lookup (IF_OIFS (ifp), &p)) + if ((rn = route_node_lookup (IF_OIFS (ifp), &p))) { rninfo = (struct ospf_interface *) rn->info; route_unlock_node (rn); @@ -559,6 +559,7 @@ ospf_new_if_params (void) UNSET_IF_PARAM (oip, retransmit_interval); UNSET_IF_PARAM (oip, passive_interface); UNSET_IF_PARAM (oip, v_hello); + UNSET_IF_PARAM (oip, fast_hello); UNSET_IF_PARAM (oip, v_wait); UNSET_IF_PARAM (oip, priority); UNSET_IF_PARAM (oip, type); @@ -600,6 +601,7 @@ ospf_free_if_params (struct interface *ifp, struct in_addr addr) !OSPF_IF_PARAM_CONFIGURED (oip, retransmit_interval) && !OSPF_IF_PARAM_CONFIGURED (oip, passive_interface) && !OSPF_IF_PARAM_CONFIGURED (oip, v_hello) && + !OSPF_IF_PARAM_CONFIGURED (oip, fast_hello) && !OSPF_IF_PARAM_CONFIGURED (oip, v_wait) && !OSPF_IF_PARAM_CONFIGURED (oip, priority) && !OSPF_IF_PARAM_CONFIGURED (oip, type) && @@ -700,6 +702,9 @@ ospf_if_new_hook (struct interface *ifp) SET_IF_PARAM (IF_DEF_PARAMS (ifp), v_hello); IF_DEF_PARAMS (ifp)->v_hello = OSPF_HELLO_INTERVAL_DEFAULT; + SET_IF_PARAM (IF_DEF_PARAMS (ifp), fast_hello); + IF_DEF_PARAMS (ifp)->fast_hello = OSPF_FAST_HELLO_DEFAULT; + SET_IF_PARAM (IF_DEF_PARAMS (ifp), v_wait); IF_DEF_PARAMS (ifp)->v_wait = OSPF_ROUTER_DEAD_INTERVAL_DEFAULT; diff --git a/ospfd/ospf_interface.h b/ospfd/ospf_interface.h index 2b129859..28d95d7e 100644 --- a/ospfd/ospf_interface.h +++ b/ospfd/ospf_interface.h @@ -55,7 +55,10 @@ struct ospf_if_params /* MTU mismatch check (see RFC2328, chap 10.6) */ DECLARE_IF_PARAM (u_char, mtu_ignore); - + + /* Fast-Hellos */ + DECLARE_IF_PARAM (u_char, fast_hello); + /* Authentication data. */ u_char auth_simple[OSPF_AUTH_SIMPLE_SIZE + 1]; /* Simple password. */ u_char auth_simple__config:1; diff --git a/ospfd/ospf_ism.c b/ospfd/ospf_ism.c index ab91e8d8..f65c68c9 100644 --- a/ospfd/ospf_ism.c +++ b/ospfd/ospf_ism.c @@ -263,9 +263,8 @@ ospf_hello_timer (struct thread *thread) ospf_hello_send (oi); /* Hello timer set. */ - OSPF_ISM_TIMER_ON (oi->t_hello, ospf_hello_timer, - OSPF_IF_PARAM (oi, v_hello)); - + OSPF_HELLO_TIMER_ON (oi); + return 0; } @@ -313,7 +312,7 @@ ism_timer_set (struct ospf_interface *oi) /* The router is trying to determine the identity of DRouter and BDRouter.
