* 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.
|
|
* ospf_lsa.c: fix up some places where an NSSA specific define,
(OSPF_LSA_LOCAL_XLT) was referenced in if statements without being
ifdef'ed by HAVE_NSSA.
|
|
* (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.c (router_lsa_flags): Set the correct flags for
router-lsa's. Eg OSPF_FLAG_ASBR is /not/ an LSA flag, its an
internal ospfd flag (just happens to have same value as
ROUTER_LSA_EXTERNAL). Set ROUTER_LSA_EXTERNAL for ASBRs,
ROUTER_LSA_BORDER for ABRs and ROUTER_LSA_NT for NSSA ABRs which
are OSPF_NSSA_ROLE_ALWAYS translators.

Subject: [zebra 19091] [PATCH] NSSA fixes try2
NSSA didn't work without problems even after my previous fixes. Seems
that I tracked down problems finally.

Fix removal of Type-7 LSAs, http://bugzilla.dishone.st/show_bug.cgi?id=18
|
|
problems with NSSA are resolved, and we can determine whether this had any
point.
|
|
It didnt solve a particular problem of Hasso's, but i'm committing it just
for posterities sakes, so i dont lose it (i'll revert it immediately).

New Revision: 212
Modified:
zebra-ag/trunk/ospfd/ospf_lsa.c
Log:
I've fixed a small opaque lsa bug which got triggered when deleting opaque
lsa of type 11. It used area->ospf->.. when area was null. This was replaced
by a ospf = ospf_lookyp(); ospf->...

Subject: [zebra 18573] PATCH ospfd: byte order error in assert statement
I found a bug in the ospfd code tickled this morning by a Type 1
LSA with exactly 62 entries (LSA length of 768, or 0x0300).
A missing ntohs in ospf_lsa.c:ospf_lsa_different() causes an assert
statement to fail, stopping ospfd.
> assert (l1->data->length > OSPF_LSA_HEADER_SIZE);
So, a length of type 768 turns into a length of 3 which is
obviously less than 20.

* sync to latest zebra CVS
* spec file: updated and added define for ospf-api/client
NB: OSPF-API has been broken by the zebra.org changes, which
has added struct ospf * as a new arg to many functions

Subject: [zebra 16823] [PATCH] Bugfix and new feature in Opaque-LSA
handling.
----- * ----- * ----- * ----- * ----- * ----- * ----- * ----- * ----- * -----
Changes 2002.12.20
1. Bug fixes
1.1 When an opaque LSA is being removed from (or added to) the LSDB,
it does not mean a change in network topology. Therefore, SPF
recalculation should not be triggered in that case.
There was an assertion failure problem "assert (rn && rn->info)"
inside the function "ospf_ase_incremental_update()", because
the upper function "ospf_lsa_maxage_walker_remover()" called it
when a type-11 opaque LSA is removed due to MaxAge.
1.2 Type-9 LSA is defined to have "link-local" flooding scope.
In the Database exchange procedure with a new neighbor, a type-9
LSA was added in the database summary of a DD message, even if
the link is different from the one that have bound to.
2. Feature enhancements
2.1 Though a "wildcard" concept to handle type-9/10/11 LSAs altogether
has introduced about a year ago, it was only a symbol definition
and actual handling mechanism was not implemented. Now it works.
