+ * (general) RFC3137 stub-router support
+ * ospfd.h: Add OSPF_OUTPUT_COST_INFINITE define.
+ (struct ospf_master) Add a OSPF_MASTER_SHUTDOWN flag for
+ options, to allow shutdown to distinguish between complete
+ shutdown and shutdown of a subset of ospf instances.
+ (struct ospf)
+ Add stub_router_{startup,shutdown_}time, configuration of startup
+ and shutdown time for stub-router.
+ Add t_graceful_shutdown struct thread, timer for graceful
+ shutdown, if needed.
+ (struct ospf_area) Add stub_router_state - run time state of
+ stub-router for an area. Add flags for ADMIN, IS and WAS
+ states.
+ Add t_stub_router, timer thread to resend router-lsa for an
+ area.
+ * ospf_lsa.c: (ospf_link_cost) new simple function to spit out
+ either the given lnks cost or infinite cost if stub-router is
+ in effect.
+ (lsa_link_{ptop,broadcast,virtuallink,ptomp}_set) use
+ previous function for transit-links.
+ (ospf_stub_router_timer) timer thread for end of startup stub
+ router. Change state as required for the area and setup
+ re-origination of router-lsa.
+ (ospf_stub_router_check) Check/do whether stub-router should be
+ enabled, and whether it requires timer to be setup.
+ (ospf_router_lsa_new) call previous function at top.
+ (ospf_router_lsa_originate) no external callers, made static.
+ * ospf_lsa.h: (ospf_router_lsa_originate) removed.
+ * ospf_main.c: (sigint) make static.
+ remove call to exit, as ospf_terminate now deals with
+ exiting.
+ * ospf_route.c: (ospf_terminate) removed, now in ospfd.c.
+ * ospf_vty.c: (show_ip_ospf_area) print out state of
+ stub-router, if active.
+ (show_ip_ospf) print out configuration of stub-router
+ support, and details of graceful-shutdown if the timer is
+ active.
+ ((no)?ospf_max_metric_router_lsa_{admin,startup,shutdown}) new
+ commands to (de-)?configure stub-router support.
+ (config_write_stub_router) write out config of stub-router.
+ (ospf_config_write) call previous.
+ (ospf_vty_init) install the new stub-router commands.
+ * ospfd.c: various functions made static.
+ (ospf_new) Set defaults for stub-router. Graceful shutdown
+ is made to default on, just to be adventerous.
+ (ospf_graceful_shutdown_finish) new function, final part of
+ shutdown.
+ (ospf_graceful_shutdown_timer) timer thread wrapper for
+ graceful-shutdown.
+ (ospf_graceful_shutdown_check) check whether to setup timer
+ for shutdown or proceed directly to final shutdown.
+ (ospf_terminate) moved here from ospf_route.c, call
+ ospf_finish for each instance.
+ (ospf_finish) renamed to ospf_finish_final and made static.
+ (ospf_finish) new function, exported wrapper around
+ ospf_graceful_shutdown_check.
+ (ospf_finish_final) complete shutdown of an instance.
+ Add missing TIMER_OFF's of two timer threads.
+ (ospf_area_free) opaque self lsa timer should be turned off.
