[ospfd] Allow ospf_lsa_unlock to NULL out callers' LSA pointers upon free
2006-07-26 Paul Jakma <paul.jakma@sun.com> * 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.
