2005-10-21 Paul Jakma <paul.jakma@sun.com>
+ * (general) SPF millisecond resolution timer with adaptive,
+ linear back-off holdtime. Prettification of ospf_timer_dump.
+ * ospf_dump.c: (ospf_timeval_dump) new function. The guts of
+ ospf_timer_dump, but made to be more dynamic in printing out
+ the relative timeval, sliding the precision printed out
+ according to the value.
+ (ospf_timer_dump) guts moved to ospf_timeval_dump.
+ * ospf_dump.h: export ospf_timeval_dump.
+ * ospf_flood.c: (ospf_flood) remove gettimeofday, use
+ the libzebra exported recent_time instead, as it's not
+ terribly critical to have time exactly right - the dropped
+ LSA will be retransmited to us if we don't ACK it.
+ * ospf_packet.c: (ospf_ls_upd_timer) Ditto, but here we're
+ not transmitting, just putting LSA back on update transmit list.
+ * ospfd.h: delay and holdtimes should be unsigned.
+ Add spf_max_holdtime and spf_hold_multiplier.
+ Update default defines for delay and hold time to be in msec.
+ (struct ospf) change the SPF timestamp to a struct timeval.
+ Remove ospf_timers_spf_(un)?set.
+ * ospfd.c: (ospf_timers_spf_{set,unset}) removed.
+ (ospf_new) initialise spf_max_holdtime and spf_hold_multiplier
+ * ospf_spf.c: (ospf_spf_calculate) SPF timestamp is a timeval
+ now, update with gettimeofday.
+ (ospf_spf_calculate_schedule) Change SPF timers to millisecond
+ resolution.
+ Make the holdtime be adaptive, with a linear increase in
+ holdtime ever consecutive SPF run which occurs within holdtime
+ of previous SPF, bounded by spf_max_holdtime.
+ * ospf_vty.c: Update spf timers commands.
+ (ospf_timers_spf_set) trivial helper.
+ (ospf_timers_throttle_spf_cmd) new command to set SPF delay,
+ initial hold and max hold times with millisecond resolution.
+ (ospf_timers_spf_cmd) Deprecated. Accept the old values,
+ convert to msec, truncate to new limits.
+ (no_ospf_timers_throttle_spf_cmd) set timers to defaults.
+ (no_ospf_timers_spf_cmd) deprecated form, same as previous.
+ (show_ip_ospf_cmd) Display SPF parameters and times.
+ (show_ip_ospf_neighbour_header) Centralise the 'sh ip os ne'
+ header.
+ (show_ip_ospf_neighbor_sub) Fix the field widths. Get rid of
+ the multiple spaces which were making the lines even longer.
+ (show_ip_ospf_neighbor_cmd) Use show_ip_ospf_neighbour_header
+ (show_ip_ospf_neighbor_all_cmd) ditto and fix the field
+ widths for NBMA neighbours.
+ (show_ip_ospf_neighbor_int) Use header function.
+ (show_ip_ospf_nbr_nbma_detail_sub) use sizeof for timebuf,
+ local array - safer.
+ (show_ip_ospf_neighbor_detail_sub) ditto
+ (ospf_vty_init) install the new SPF throttle timer commands.
+
+2005-10-21 Paul Jakma <paul.jakma@sun.com>
+
* (general) OSPF fast, sub-second hello and 1s dead-interval
support.
* ospf_dump.c: (ospf_timer_dump) Print out milliseconds too.
