ospf_lsdb_free had been called. (efence caught this one).
This bug is present in zebra.org CVS
2. It fixes my previous ospf_network_match_iface patch ([zebra 17352])
- i lost a couple of checks in ospf_network_run() by mistake. this
patch isnt in zebra.org CVS, but it would be nice to have it once it
works.
This hopefully fixes the 'assert rn->info' problems people had with
zebra-pj yesterday.

may return an existing node. (if the code wants a /new/ node why not use
route_node_set? if it doesnt mind - then the assert is wrong).
this bug is in zebra.org CVS. (must be an extremely rare/unlikely bug
though).

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.

[ Your display is set for the "ISO-8859-1" character set. ]
[ Some characters may be displayed incorrectly. ]
Hi Ishiguro-san,
Here is my problem analysis against the case that the ospfd crashes
when an interface is brought down.
When the ospfd receives a ZEBRA message "ZEBRA_INTERFACE_DOWN" from
zebra daemon, the ospfd performs bunch of ospf-interface cleanup for
the notified zebra-interface.
There are cases that neighbor instance "nbr", which will be removed
afterward, may scheduled in the NSM thread event queue. And when the
NSM event thread is fired, dereference for this already freed "nbr"
pointer causes SIGSEGV.
Please take a look at following timeline of processing sequences.
