2013-01-07ospf: Convert MAX_AGE LSA list to treeDinesh Dutt
Store the MaxAge LSA list in a tree instead of a linked list for efficient access. Walking the list can be quite inefficient in some large systems and under certain tests. ospfd maintains the list of LSA's that have been MaxAge'd out in a separate linked list for removal by a remover/walker thread. When a new LSA is to be installed, the old LSA is ejected and when it is ejected, the MaxAge LSA list is traversed to ensure that the old LSA is also removed from this list if it exists on this list. When a large number (> 5K) MaxAge LSAs are bombarding the system, walking this list takes a significant time causing timers to fire and actions to be taken such as expiring neighbors due to expiry of DeadInterval (especially when timer is really low, <= 12s), creating a spiral of instability. By making this MaxAge LSA list be a tree, this problem is mitigated.

2013-01-07ospf: forward ref. of areas for "max-metric router-lsa administrative" cmdAyan Banerjee
In the event areas are created at a later point of time with respect to the playback of the "max-metric router-lsa administrative" command, those areas do not get into indefinite max-metric mode. This patch is inteneded to store the configuration and apply it to all future areas that may be created. In the process, some other bugs that were there with respect to restart etc are fixed up. Tested locally to see that the fix works across multiple areas and across multiple restarts.

2012-10-25ospfd: respect max-metric over configured cost for summary LSAsJR Rivers
ISSUE When max-metric router-lsa administrative is invoked on an ABR created with... area <area> range <addr/mask> the summary LSAs are sent out with 65535 (max-metric) added to the normal cost. When max-metric router-lsa administrative is invoked on an ABR created with... area <area> range <addr/mask> cost <cost> the summary LSAs are sent out with <cost> (the max-metric is ignored). This second behavior effectively incapacitates the max-metric function. PATCH This patch evaluates the state of the router and if it's isolated as a stub router (rfc3137) via `max-metric router-lsa`, we unconditionally uses the value of 0xff0000 when advertising summary LSAs.

2010-12-08ospfd: Fix maxage/flush to not try flood twice, remember maxages for longerPaul Jakma
2006-05-30 Paul Jakma <paul.jakma@sun.com> * (general) Fix confusion around MaxAge-ing and problem with high-latency networks. Analysis and suggested fixes by Phillip Spagnolo, in [quagga-dev 4132], on which this commit expands slightly. * ospf_flood.{c,h}: (ospf_lsa_flush) new function. Scope-general form of existing flush functions, essentially the dormant ospf_maxage_flood() but without the ambiguity of whether it is responsible for flooding. * ospf_lsa.c: (ospf_lsa_maxage) Role minimised to simply setup LSA on the Maxage list and schedule removal - no more. ospf_lsa_flush* being the primary way to kick-off flushes of LSAs. Don't hardcode the remover-timer value, which was too short for very high-latency networks. (ospf_maxage_lsa_remover) Just do what needs to be done to remove maxage LSAs from the maxage list, remove the call to ospf_flood_through(). Don't hardcode remove-timer value. (ospf_lsa_{install,flush_schedule}) ospf_lsa_flush is the correct entrypoint to flushing maxaged LSAs. (lsa_header_set) Use a define for the initial age, useful for testing. * ospf_opaque.c: (ospf_opaque_lsa_refresh) ditto. (ospf_opaque_lsa_flush_schedule) ditto. * ospfd.h: ({struct ospf,ospf_new}) Add maxage_delay parameter, interval to wait before running the maxage_remover. Supply a suitable default. Add a define for OSPF_LSA_INITIAL_AGE, see lsa_header_set().
2010-12-08ospfd: Unify router and network LSA refresh logic with general refresherPaul Jakma
* (general) Get rid of the router and network LSA specific refresh timers and make the general refresher do this instead. Get rid of the twiddling of timers for router/network LSA that was spread across the code. This lays the foundations for future, general LSA refresh improvements, such as making sequence rollover work, and having generic LSA delays. * ospfd.h: (struct ospf) Bye bye to the router-lsa update timer thread pointer. (struct ospf_area) and to the router-lsa refresh timer. * ospf_interface.h: Remove the network_lsa_self timer thread pointer * ospf_lsa.h: (struct ospf_lsa) oi field should always be there, for benefit of type-2/network LSA processing. (ospf_{router,network}_lsa_{update_timer,timer_add}) no timers for these more (ospf_{router,network}_lsa_update) more generic functions to indicate that some router/network LSAs need updating (ospf_router_lsa_update_area) update router lsa in a particular area alone. (ospf_{summary,summary_asbr,network}_lsa_refresh) replaced by the general ospf_lsa_refresh function. (ospf_lsa_refresh) general LSA refresh function
2009-12-03ospfd: make local functions staticStephen Hemminger
This code is only used one place and can be made local. Gcc is smart enough to inline local functions if it wants to. The function also has a big chunk of compatiablity code that is no longer used; since quagga is now in a version control system the source does not need to be used as a historical reference.
2009-06-19[ospfd/BSD] add missing UINT16_MAX - picked up from FreeBSD ports patchJeremy Jackson
Should probably have AC_TYPE_UINT16_T in configure.ac to make it really clean... and a fresh import of gnulib, the existing copy of gnulib seems to be manually put some stuff in zebra.h. I'm leaving that alone for now, since a fresh import will probably clean up a lot of cruft and it would be a duplicated effort to fix some things now. The FreeBSD port 0.99.11_1 files/patch-ospfd-ospfd.h can probably go away after this is applied.

2008-09-02[ospfd] Restructure opsf_if_update() and ospf_network_run()Joakim Tjernlund
Add an struct interface paramenter and adjust the affected code accordingly. The old code was a mess looping over all interfaces several times when one interface was added/changed. * ospfd/ospfd.h: Add struct interface parameter to ospf_if_update() * ospfd/ospf_zebra.c: Add ifp arg to ospf_if_update() calls. (ospf_interface_address_delete) delete ospf_if_update() call, redundant as function calls ospf_if_free() itself. * ospfd/ospfd.c: (ospf_network_unset) handle deconfiguration here, rather than ospf_if_update. (ospf_network_run_interface) ospf_network_run, for any given interface. (ospf_network_run) move guts to previous, and use it. (ospf_if_update) Adjust to take struct interface as argument, as all callers have a specific ifp in mind. Iterate over ifp's connected list and call ospf_network_run_interface instead of ospf_network_run, turning this path into O(nm) rather than O(n^2). Adjust all code dealing with opsf_if_update and ospf_network_run to pass the new struct interface * arg. (some minor modifications and bug-additions by Paul Jakma).

(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.

(ospf_finish) Call stream_free(ospf->ibuf. * ospf_packet.c: (ospf_read) Call stream_reset(ospf->ibuf) and then pass it to ospf_recv_packet for use in receiving the packet (instead of allocating a new stream for each packet received). Eliminate all calls to stream_free(ibuf). (ospf_recv_packet) The struct stream *ibuf is now passed in as an argument. No need to use recvfrom to peek at the packet header (to see how big it is), just use ospf->ibuf which is always large enough (this eliminates a system call to recvfrom). Therefore, no need to allocate a stream just for this packet, and no need to free it when done.

* (global) Const char update and signed/unsigned fixes. * (various headers) size defines should be unsigned. * ospf_interface.h: remove duplicated defines, include the authoritative header - though, these defines should probably be moved to a dedicated header, or ospfd.h. * ospf_lsa.h: (struct lsa) ls_seqnum should be unsigned. * ospf_packet.c: (ospf_write) cast result of shift to unsigned.

* (global): Add/fixup NSSA ABR translation functionality * ospfd.h: Adjust the NSSA ROLE defines. Rename STATE to TRANSLATE. Rename the LSA_NSSA_GET define to LSA_OPTIONS_NSSA_GET. * ospfd.c: Adjust to match changes to ospfd.h * ospf_te.c: Adjust to match change to LSA_NSSA_GET. * ospf_lsa.h: slights reformatting. Add new NSSA functions, ospf_translated_nssa_compare() (not currently used), ospf_translated_nssa_refresh() and ospf_translated_nssa_originate(). * ospf_lsa.c: Implemented aforementioned new functions. Fix up several NSSA hooks to /not/ be called for Type-5s which are translated. Add additional hooks. Set the ROUTER_LSA_NT bit in router-lsa flags if ABR does translation. New function, ospf_lsa_translated_nssa_new() implemented. Dont register translated LSAs for refreshing - instead we implicitly rely on the ASBR refreshing the Type-7, and refresh the translated Type-5 at the same time. Some minor reformatting. Extra debug info added. Also, existing debug statements modified to report LSA Id. * ospf_flood.c: call ospf_translated_nssa_refresh() when refreshing Type-7. minor reformatting. * ospf_dump.c: Dump NSSA LSAs. * ospf_asbr.h: slight reformatting. Export ospf_external_route_lookup() (though, not used. probably will undo this). * ospf_abr.c: Slight reformatting in many places. Update to match ospfd.h changes. (ospf_abr_translate_nssa): make it work, using the new ospf_lsa translation functions. (Several places): change struct prefix * to struct prefix_ipv4 *. (might as well do the casts at higher levels). Add more debug info. (ospf_abr_announce_stub_defaults): announce default to NSSA areas too. (ospf_abr_announce_nssa_defaults): do nothing. this function probably should die. (see ospf_abr_announce_stub_defaults). (ospf_abr_task_timer): run NSSA tasks.

* ospfd.h (struct ospf_area): remove NSSATranslator. Add NSSATranslatorState and NSSATranslatorStabilityInterval (currently not used). (global): add OSPF_NSSA_TRANS_STABLE_DEFAULT, default for NSSATranslatorStabilityInterval. Update the LSA_NSSA_GET to reflect struct ospf_area changes.
2003-05-29ospfd/ospfd.h: Change delay and holdtime to 1s. More appropriate values forpaul
the class of machines which zebra runs on than the original defaults which were taken from IOS (and even IOS uses much lower times these days). Lower values greatly help with convergence. Ideally, we'd use even lower times, but thread_add_timer() api will need to be modified to use milliseconds. (eg JunOS uses 100ms for delay, and 700ms for hold time, iirc from Hasso).
2003-04-07[zebra 18626] move zebra socket paths to configure.acpaul
moved definition of the various socket paths from the per daemon header files into configure.ac. it will set the paths to be in the directory specified by --localstatedir=<prefix> or otherwise will try to guess as best it can ( a la pid file path detection - which probably should try reference ${prefix} too). the present hardcoded socket path, /tmp, isnt really correct. should be in /var somewhere really.
