+Changes 2001.12.03
+
+1. Bug fixes
+
+ 1.1 Though a new member "oi" has added to "struct ospf_lsa" to control
+ flooding scope of type-9 Opaque-LSAs, the value was always NULL
+ because no one set it.
+
+ 1.2 In the function "show_ip_ospf_database_summary()" and "show_lsa_
+ detail_adv_router()", VTY output for type-11 Opaque-LSAs did not
+ work properly.
+
+ 1.3 URL for the opaque-type assignment reference has changed.
+
+ 1.4 In the file "ospf_mpls_te.c", printf formats have changed to
+ avoid compiler warning messages; "%lu" -> "%u", "%lx" -> "%x".
+ Note that this hack depends on OS, compiler and their versions.
+
+ 1.5 One of attached documentation "opaque_lsa.txt" has changed to
+ reflect the latest coding.
+
+2. Feature enhancements
+
+ 2.1 Knowing that it is an ugly hack, an "officially unallocated"
+ opaque-type value 0 has newly introduced as a "wildcard",
+ which matches to all opaque-type.
+ This value must not be flooded to the network, of course.
+
+ 2.2 The Opaque-core module makes use of newly introduced hooks to
+ dispatch every LSDB change (LSA installation and deletion) to
+ preregistered opaque users.
+ Therefore, by providing appropriate callback functions as new
+ parameters of "ospf_register_opaque_functab()", an opaque user
+ can refer to every LSA instance to be installed into, or to be
+ deleted from, the LSDB.

+Changes 2001.10.31
+
+1. Bug fixes
+
+ 1.1 Since each LSA has their own lifetime, they will remain in a
+ routing domain (being stored in LSDB of each router), until their
+ age naturally reach to MaxAge or explicitly being flushed by the
+ originated router. Therefore, if a router restarted with a short
+ downtime, it is possible that previously flooded self-originated
+ LSAs might received if the NSM status is not less than Exchange.
+
+ There were some problems in the way of handling self-originated
+ Opaque-LSAs if they are contained in a received LSUpd message,
+ but not installed to the local LSDB yet.
+ Regardless of some conditions to start originating Opaque-LSAs
+ (there should be at least one opaque-capable full-state neighbor),
+ the function "ospf_flood()" will be called to flood and install
+ this brand-new looking LSA.
+ As the result, when the NSM of an opaque-capable neighbor gets
+ full, internal state inconsistency happens; a user of Opaque-LSA
+ such as MPLS-TE can refer to self-originated LSAs in the local
+ LSDB, but cannot modify their contents...
+
+ Above problems have fixed with a policy "flush it from the whole
+ routing domain and keep silent until the flushing completed".
+ By using this sweeping technique, we can be free from confusion
+ caused by self-originated LSAs received via network.
+
+ 1.2 The function "ospf_opaque_type_name()" contained massive ifdefs
+ corresponding to each "opaque-type".
+ These unnecessary ifdefs are removed completely.
+
+ 1.3 In the function "ospf_delete_opaque_functab()", there was an
+ improper loop control that causes illegal memory access.
+ Original coding was "next = nextnode (node)".
+
+ 1.4 The function "ospf_mpls_te_ism_change()" could not handle the
+ case when the ISM changes from Waiting to DR/BDR/Other.
+ So, there was a case that even if one of an ISM become
+ operational and MPLS-TE module has started, the corresponding
+ Opaque-LSA cannot be originated.
+
+ 1.5 The function "ospf_opaque_lsa_reoriginate_schedule()" did not
+ allow to be called multiple times, simply because handling
+ module for the given "lsa-type & opaque-type" already exists.
+ But this assumption seems to be wrong.
+ Change the policy to allow this function to be called multiple
+ times and let the caller to decide what should do when the
+ corresponding callback function "(* functab->lsa_originator)()"
+ is called.
+
+2. Feature enhancements
+
+ 2.1 The global bitmap "opaque" has introduced instead of former flag
+ "OpaqueCapable", to store complex conditions to handle Opaque-LSAs.
+
+ 2.2 The MPLS-TE module now referes to "draft-katz-yeung-ospf-traffic
+ -06.txt", no significant changes with 05 version, though.

+Changes 2001.08.03
+
+1. Bug fixes
+
+ 1.1 Even if the ospfd started with opaque capability enabled, when
+ the ospfd receives an unknown opaque-type (unregistered by the
+ function "ospf_register_opaque_functab()" beforehand), the LSA
+ was discarded. As the result, only the opaque-LSAs that have
+ commonly registered by opaque-capable ospf routers can be
+ flooded in a routing domain.
+
+ This behavior has fixed so that arbitrary opaque-type LSAs can
+ be flooded among opaque-capable ospf routers.
+ If the ospfd has opaque-LSA capability but disabled at runtime,
+ received opaque-LSAs can be accepted and registered to LSDB as
+ is, but not be flooded to the network; those opaque LSAs will
+ remain in LSDB until explicitly flushed by incoming LSUpd
+ messages with MaxAge, or their age naturally reaches to MaxAge.
+
+ 1.2 The function "ospf_register_opaque_functab()" did not check
+ if the entry corresponding to the given "lsa-type, opaque-type"
+ combination already exists or not.
+ This problem has fixed not to allow multiple registration.
+
+ 1.3 Since type-11 (AS external) LSAs will be flooded beyond areas,
+ there is little relationship between "struct lsa" and "struct
+ area". More specifically, the pointer address "lsa->area" can
+ be NULL if the lsa-type is 11, thus an illegal memory access
+ will happen. This problem has fixed.
+
+ 1.4 When self-originated opaque-LSAs are received via network and
+ if the corresponding opaque-type functions are not available
+ (they have already deleted) at that time, those LSAs were
+ dropped due to "unknown opaque-type" error.
+ After the problem 1.1 has fixed, those "self-originated" LSAs
+ were registered to LSDB and then flooded to the network, even
+ if the processing functions did not exist...
+
+ After all, this problem has fixed so that those LSAs should
+ explicitly be flushed from the routing domain immediately, if
+ the processing functions cannot find at that time.
+
+ 1.5 Some typo have fixed.
+

+ static int
+ opaque_lsa_originate_callback (list funclist, void *lsa_type_dependent)
+ ^^^^^
+ --- EXAMPLE ---
+
+2. Feature enhancements
+
+ 2.1 According to the description of rfc2328 in section 10.8, any
+ change in the router's optional capabilities should trigger
+ the option re-negotiation procedures with neighbors.
+
+ --- EXCERPT ---
+ If for some reason the router's optional
+ capabilities change, the Database Exchange procedure should be
+ restarted by reverting to neighbor state ExStart.
+ --- EXCERPT ---
+
+ For the opaque-capability changes, this feature has implemented.
+ More specifically, if "ospf opaque-lsa" or "no ospf opaque-lsa"
+ VTY command is given at runtime, all self-originated LSAs will
+ be flushed immediately and then all neighbor status will be
+ forced to ExStart by generating SeqNumberMismatch events.
+
+ 2.1 When we change opaque-capability dynamically (ON -> OFF -> ON),
+ there was no trigger at "OFF->ON" timing to reactivate opaque
+ LSA handling modules (such as MPLS-TE) that have once forcibly
+ stopped at "ON->OFF" timing.
+ Now this dynamic reactivation feature has added.
+
+ 2.2 The MPLS-TE module now referes to "draft-katz-yeung-ospf-traffic
+ -05.txt", no significant changes with 04 version, though.
