* rt_netlink.c: (netlink_link_change) If the status of an operative interface changes (e.g. MTU changes), the client daemons should be notified by calling zebra_interface_up_update. Previously, the information was being updated in zebra's interface structure, but the clients were not notified of changes to an operative interface. * ospf_zebra.c: (ospf_interface_state_up) If the MTU of an operative interface changes, print a debug message and call ospf_if_reset() to simulate down/up on the interface. * ospf_interface.h: Declare new function ospf_if_reset(). * ospf_interface.c: (ospf_if_reset) New function to call ospf_if_down and ospf_if_up for all ospf interfaces attached to an interface.

* ospf_interface.h: Improve passive_interface comment. Add new multicast_memberships bitmask to struct ospf_interface to track active multicast subscriptions. Declare new function ospf_if_set_multicast. * ospf_interface.c: (ospf_if_set_multicast) New function to configure multicast memberships properly based on the current multicast_memberships status and the current values of the ospf_interface state, type, and passive_interface status. (ospf_if_up) Remove call to ospf_if_add_allspfrouters (this is now handled by ism_change_state's call to ospf_if_set_multicast). (ospf_if_down) Remove call to ospf_if_drop_allspfrouters (now handled by ism_change_state). * ospf_ism.c: (ospf_dr_election) Remove logic to join or leave the DRouters multicast group (now handled by ism_change_state's call to ospf_if_set_multicast). (ism_change_state) Add call to ospf_if_set_multicast to change multicast memberships as necessary to reflect the new interface state. * ospf_packet.c: (ospf_hello) When a Hello packet is received on a passive interface: 1. Increase the severity of the error message from LOG_INFO to LOG_WARNING; 2. Add more information to the error message (packet destination address and interface address); and 3. If the packet was sent to ospf-all-routers, then try to fix the multicast group memberships. (ospf_read) When a packet is received on an interface whose state is ISM_Down, enhance the warning message to show the packet destination address, and try to update/fix the multicast group memberships if the packet was sent to a multicast address. When a packet is received for ospf-designated-routers, but the current interface state is not DR or BDR, then increase the severity level of the error message from LOG_INFO to LOG_WARNING, and try to fix the multicast group memberships. * ospf_vty.c: (ospf_passive_interface) Call ospf_if_set_multicast for any ospf interface that may have changed from active to passive. (no_ospf_passive_interface) Call ospf_if_set_multicast for any ospf interface that may have changed from passive to active. (show_ip_ospf_interface_sub) Show multicast group memberships.

* *.c: Change level of debug messages to LOG_DEBUG.
2004-10-19OK. Here it is - PtP patch from Andrew J. Schorr. No problems with ospfd,hasso
ripd might need some more testing though.
2004-09-23Remove usage of evil list and listnode typedefs.hasso
2004-08-31Assorted changes from work at BBN. Most are minor, and several are ingdt
support of more significant changes not in this commit. The last item in the ChangeLog below may be needed for p2mp to work correctly. 2004-08-31 David Wiggins <dwiggins@bbn.com> * hash.c (hash_iterate): Save next pointer before calling procedure, so that iteration works even if the called procedure deletes the hash backet. * linklist.h (listtail): new macro, not yet used. 2004-08-31 David Wiggins <dwiggins@bbn.com> * ospf_spf.c (ospf_spf_calculate): Many more comments and debug print statements. New function ospf_vertex_dump used in debugging. 2004-08-31 David Wiggins <dwiggins@bbn.com> * ospf_spf.h (struct vertex): Comments for flags and structure members. 2004-08-31 David Wiggins <dwiggins@bbn.com> * ospf_route.c: When finding an alternate route, log cost as well. 2004-08-31 David Wiggins <dwiggins@bbn.com> * ospf_interface.c (ospf_lookup_if_params): Initialize af in struct prefix allocated on stack. 2004-08-31 David Wiggins <dwiggins@bbn.com> * ospf_packet.c (ospf_ls_ack_send_delayed): In p2mp mode, send acks to AllSPFRouters, rather than All-DR.
2004-06-20Remove ifdef's HAVE_NSSA. NSSA support is stable enough.hasso
2004-05-052004-05-05 Paul Jakma <paul@dishone.st>paul
* ospf_interface.c: (ospf_vl_set_params) Catch changes of interface address for either end of a virtual-link, and hence potential cost changes.
2004-04-082004-04-08 Paul Jakma <paul@dishone.st>paul
* ospf_spf.h: Add backlink field to struct vertex * ospf_spf.h: (ospf_vertex_new) initialise backlink (ospf_lsa_has_link) return index of link back to vertex V from candidate vertex W, or -1 if no link exists. (ospf_spf_next) save backlink index for candidate vertex * ospf_interface.c: (ospf_vl_set_params) Use the backlink index to determine correct address for virtual-link peers. Fall back to older "pick first link" method if no backlink index exists.
2004-02-172004-02-17 Paul Jakma <paul@dishone.st>paul
* ospf_zebra.c: (ospf_interface_delete) Do not delete the interface params, nor the interface structure, if an interface delete message is received from zebra. * ospf_interface.c: (ospf_if_delete_hook) Delete the interface params and interface, ie that which was previously removed in (ospf_interface_delete) above.
2004-02-11Don't crash when attempting to read path->oi->ifp if oi doesn't exist anyhasso
more. I'm not sure if this read should be attempted at all, but I'm trying to keep code safe AND stable.
2003-11-102003-11-10 Claus Endres <claus@endresconsulting.com>paul
* ospfd/ospf_interface.c: (ospf_if_table_lookup) grab reference to rn->info /before/ calling route_unlock_node() as some systems may deliberately poison freed memory, eg FreeBSD 5.1. see [quagga-dev 417].
2003-10-152003-10-15 Paul Jakma <paul@dishone.st>paul
* ospfd/ospf_interface: (ospf_if_lookup_table) fix compile errors from previous patch. doh.
2003-10-152003-10-15 Paul Jakma <paul@dishone.st>paul
* ospfd/ospf_interface: (ospf_if_lookup_table) new function to lookup oi for a given prefix in a given interfaces table of oi's. (ospf_if_new) use ospf_if_lookup_table to deal with zebra reporting new interface multiple times. NB: This patch is a complete plaster-band of a hack. First, why is zebra reporting interface events multiple times? Second, why does ospfd maintain so many damn lists and tables relating to oi's - these should be reconciled into one or two tables.
2003-08-012003-08-01 Cougar <cougar@random.ee>paul
* lib/if.c: (if_cmp_func) new function, compare interface names in alphabetical order. (if_create) Take name as argument and add interface in sorted order. (if_get_by_name),(interface_cmd) fixup calls to if_create - see above. (if_init) register list comparison function. * lib/if.h: Add comparison function, modify if_create prototype. * lib/zclient.c: Modify call to if_create. * ospfd/ospf_interface.c: (ospf_vl_new) modify call to if_create. change sprintf to snprintf. * zebra/kernel_socket.c: (ifm_read) modify call to if_create.
2003-06-222003-06-19 "Suraev, Vadim" <vadim.suraev@terayon.com>paul
* ospf_interface.c (ospf_vl_set_params): new router LSA is not generated when the cost of the routing entry for the virtual link endpoint has changed. If the cost to reach the virtual link's endpoint has changed, add router LSA timer for the backbone area.
2003-06-062003-06-07 Paul Jakma <paul@dishone.st>paul
* Revert Cougar's sort interface names patch, causes problems with enabling of interfaces for OSPF in ospfd.
2003-06-05Patch from Cougar - sort iflist by name.hasso
2003-06-04From: kamatchi soundaram <kamatchi@tdd.sj.nec.com>paul
Subject: [zebra 19263] Another memory leak!! is zebra OSPF This memory leak gets into picture whenever any interface goes down. Problem found and desctription: Whenever the interface goes down, the "def_params" (member of ospf_if_info) structure memory is not freed. Fix made: added the following line to free the "def_params" memory of ospf_if_info before calling the "XFREE(MTYPE_OSPF_IF_INFO, ifp->info);" The added line is: ospf_del_if_params ((struct ospf_if_params *) IF_DEF_PARAMS (ifp));

Subject: [zebra 19262] Re: Memory leak in OSPF Fix applied for Kamatchi's original report was to remove the auth_crypt initialisation from the wrong function. This should fix that.
2003-06-03From: kamatchi soundaram <kamatchi@tdd.sj.nec.com>paul
Subject: [zebra 19259] Memory leak in OSPF The detail of the memory leak follows: File name: ospf_interface.c Function name: ospf_if_new_hook(). Type of leak: Overwriting the already allocated memory. Problem found and description: The ospf_new_if_params() fn allocates a memory for "auth_crypt" which is overwritten, down in the fn (ospf_if_new_hook) by explicitely allocating a memory for the same "auth_crypt". Fix: remove allocation from ospf_new_if_params()
2003-05-24Fix missing bracket from previous commit.paul
2003-05-242003-05-24 Kenji Yabuuchipaul
* ospf_interface.c(ospf_if_lookup_recv_if): Use the most specific match for interface lookup.

2003-04-042003-04-04 Paul Jakma <paul@dishone.st>paul
* Sync to Zebra CVS * Fix lib/thread.h leak * Fix small Opaque LSA leak * Do not configure OSPF interfaces for secondary addresses * vtysh fixes from Hasso * Dave Watson's missing ntohs fix
2003-03-28Remove redundant memsetpaul
2003-03-252003-03-25 Paul Jakma <paul@dishone.st>paul
* 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
2003-02-18 fixes an assert which doesnt seem to take into account that route_node_getpaul
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).
