The function is implemented in ospf_lsa.c, move its "extern" declaration
to ospf_lsa.h for consistency.
|
|
* ospf_spf.c
* ROUTER_LSA_TOS_SIZE: prepend OSPF_ and move to ospf_lsa.h
* ROUTER_LSA_MIN_SIZE: replace with existing OSPF_ROUTER_LSA_LINK_SIZE
|
|
* ospfd: Refresher logic cleanup broke OSPF opaque, which does its own thing
with regard to refresher logic and which also, in the protocol, requires
implementations to keep state of which OI an LSA is received on (rather
than providing information in the LSA to allow it to be looked up - as
other LSAs requiring such assocation were careful to do).
* ospf_lsa.h: (struct ospf_interface) Add back the pointer to oi, but only
for type-9 now.
* ospf_nsm.c: (ospf_db_summary_add) check the oi actually exists first -
doesn't obviate the need for opaque to ensure oi pointers get cleaned up
when ospf_interfaces disappear.
* ospf_opaque.{c,h}: (ospf_opaque_functab,ospf_opaque_lsa_refresh) Refresher
LSA functions now need to return the LSA to the general refresh logic,
to indicate whether the LSA was refreshed.
|
|
* ospf_lsa.h: (struct ospf_lsa) remove oi pointer
* ospf_lsa.c: (ospf_network_lsa_refresh) instead of keeping a pointer, just
lookup the oi when it's needed. This decouples network LSA from oi lifetime
and avoids having to invalidate pointers in LSAs when an oi changes,
simplifying the code.

|
* (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

Doing redistribute delete with full BGP table was taking
30 minutes, this drops it down to less than a second.
* ospf_lsa.c: (ospf_lsa_maxage) When flushing lots of entries the
performance is terrible because it looks up each LSA entry through
ospf_lsa_maxage_exist before deleting causing O(N^2) performance. Use a
new OSPF_LSA_MAXAGE flag instead of scan - and maintain it.
(ospf_lsa_maxage_exist) removed
(ospf_lsa_maxage_delete) maintain OSPF_LSA_MAXAGE flag

* ospf_lsa.{c,h}: (ospf_lsa_unlock) Change to take a double pointer
to the LSA to be 'unlocked', so that, if the LSA is freed, the
callers pointer to the LSA can be NULLed out, allowing any further
use of that pointer to provoke a crash sooner rather than later.
* ospf_*.c: (general) Adjust callers of ospf_lsa_unlock to match
previous. Try annotate 'locking' somewhat to show which 'locks'
are protecting what LSA reference, if not obvious.
* ospf_opaque.c: (ospf_opaque_lsa_install) Trivial: remove useless
goto, replace with return.
* ospf_packet.c: (ospf_make_ls_ack) Trivial: merge two list loops,
the dual-loop predated the delete-safe list-loop macro.

* ospf_lsa.c: (ospf_router_lsa_new) dont take reference to the
stream data until it is constructed, data reference is
volatile due to the potential resize in link_info_set
2006-01-18 Paul Jakma <paul.jakma@sun.com>
* ospf_lsa.c: (link_info_set) Resize the stream if required and
possible. Return number of links added.

|
|
* (general) RFC3137 stub-router support

(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.

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.

shutdown.
(ospf_graceful_shutdown_timer) timer thread wrapper for
graceful-shutdown.
(ospf_graceful_shutdown_check) check whether to setup timer

* (general) extern and static qualifiers added.
unspecified arguments in definitions fixed, typically they should
be 'void'.
function casts added for callbacks.
Guards added to headers which lacked them.
Proper headers included rather than relying on incomplete
definitions.
gcc noreturn function attribute where appropriate.
* ospf_opaque.c: remove the private definition of ospf_lsa's
ospf_lsa_refresh_delay.
* ospf_lsa.h: export ospf_lsa_refresh_delay
* ospf_packet.c: (ospf_make_md5_digest) make *auth_key const,
correct thing to do - removes need for the casts later.
* ospf_vty.c: Use vty.h's VTY_GET_INTEGER rather than ospf_vty's
home-brewed versions, shuts up several warnings.
* ospf_vty.h: remove VTY_GET_UINT32. VTY_GET_IPV4_ADDRESS and
VTY_GET_IPV4_PREFIX moved to lib/vty.h.
* ospf_zebra.c: (ospf_distribute_list_update_timer) hacky
overloading of the THREAD_ARG pointer should at least use
uintptr_t.
|
|
* ospf_lsdb.h: Export ospf_lsdb_clean_stat() function.
* ospf_spf.h: Add link to the LSA stat structure into vertex.
* ospf_spf.c: New functions cmp() and update_stat() to manage
candidates. Remove ospf_spf_has_vertex(), ospf_vertex_lookup(),
ospf_install_candidate() and ospf_spf_register() functions not needed
any more. Update ospf_vertex_new(), ospf_spf_next() and
ospf_spf_calculate() functions to use pqueue instead of linked list.
|
|
* (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.
|
|
|
|
* ospf_lsa.h: Add OSPF_LSA_PREMATURE_AGE flag.
* ospf_lsa.c: added better debug comments. check sequence number in
ospf_lsa_install. ospf_maxage_lsa_remover() checks for
OSPF_LSA_PREMATURE_AGE and re-originates the lsa after ls_acks are
received.
* ospf_flood.c: improve debug statement- print ls_seqnum.
|
|
* (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.
|
|
* ospf_lsa.h: elaborate on comment for ROUTER_LSA_NT
add IS_ROUTER_LSA_NT macro.
