2006-01-11[ospfd] Bug #234. Fix nbr_self reinitialisation after down/up.paul
2006-01-10 Len Sorensen <lennartsorensen@ruggedcom.com> * (general) Bug #234, see also [quagga-dev 3902]. Fix problem with nbr_self not being properly reinitialised when an interface comes up, after having been down. Some re-arrangement done by Paul Jakma, any bugs introduced on top of Len's suggested changes are his. * ospf_neighbor.c: (ospf_nbr_add_self) centralise initialisation of nbr_self parameters here. * ospf_interface.c: (ospf_if_new) deleting initialisation of parameters of nbr_self, just rely on call to ospf_nbr_add_self. (ospf_if_cleanup) ditto. * ospfd.c: (ospf_network_run) ditto.

* (general) OSPF fast, sub-second hello and 1s dead-interval support. A warning fix. Millisec support for ospf_timer_dump. Change auto-cost ref-bandwidth to add a comment to write out of config, rather than printing annoying messages to vty on startup. * ospf_dump.c: (ospf_timer_dump) Print out milliseconds too. Callers typically specify a length of 9, so most see millisecs unless they specify the additional length. * ospf_interface.h: (struct ospf_interface) new interface param, fast_hello. * ospf_interface.c: (ospf_if_table_lookup) add brackets, gcc warning fix. (ospf_new_if_params) Initialise fast_hello param. (ospf_free_if_params) Check whether fast_hello is configured. (ospf_if_new_hook) set fast_hello to default. * ospf_ism.h: Wrap OSPF_ISM_TIMER_ON inside do {} while (0) to prevent funny side-effects from its if statement when this macro is used conditionally by other macros. (OSPF_ISM_TIMER_MSEC_ON) new macro, set in milliseconds. (OSPF_HELLO_TIMER_ON) new macro to set hello timer according to whether fast_hello is set. * ospf_ism.c: Update all setting of the hello timer to use either OSPF_ISM_TIMER_MSEC_ON or OSPF_HELLO_TIMER_ON. The former is used when hello is to be sent immediately. * ospf_nsm.c: ditto * ospf_packet.c: (ospf_hello) hello-interval is not checked for mismatch if fast_hello is set. (ospf_read) Annoying nit, fix "no ospf_interface" to be debug rather than a warning, as it can be perfectly normal to receive packets when logical subnets are used. (ospf_make_hello) Set hello-interval to 0 if fast-hellos are configured. * ospf_vty.c: (ospf_auto_cost_reference_bandwidth) annoying nit, don't vty_out if this command is given, it gets tired quick. (show_ip_ospf_interface_sub) Print the hello-interval according to whether fast-hello is set or not. Print the extra 5 millisec characters from (ospf_timer_dump) if fast-hello is configured. (ospf_vty_dead_interval_set) new function, common to all forms of dead-interval command, to set dead-interval and fast-hello correctly. If a dead-interval is given, unset fast-hello, else if a hello-multiplier is set, set dead-interval to 1 and fast-hello to given multiplier. (ip_ospf_dead_interval_addr_cmd) use ospf_vty_dead_interval_set(). (ip_ospf_dead_interval_minimal_addr_cmd) ditto. (no_ip_ospf_dead_interval) Unset fast-hello. (no_ip_ospf_hello_interval) Bug-fix, unset of hello-interval should set it to OSPF_HELLO_INTERVAL_DEFAULT, not OSPF_ROUTER_DEAD_INTERVAL_DEFAULT. (config_write_interface) Write out fast-hello. (ospf_config_write) Write a comment about "auto-cost reference-bandwidth" having to be equal on all routers. Hopefully just as noticeable as old practice of writing to vty, but less annoying. (ospf_vty_if_init) install the two new dead-interval commands. * ospfd.h: Add defines for OSPF_ROUTER_DEAD_INTERVAL_MINIMAL and OSPF_FAST_HELLO_DEFAULT.

* (general) SPF memory management cleanup and fix for rare double-free bug. * ospf_spf.h: (struct vertex_parent) New struct to hold parent specific data, eg the backlink and the parent vertex pointer, and point to the appropriate general struct vertex_nexthop. (struct vertex_nexthop) remove parent vertex pointer, so this struct can be shared across vertices. (struct vertex) rename list child to list children. Remove list of nexthops, replace with list of vertex_parents. * ospf_spf.c: (update_stat) trivial, remove cast from void *. (vertex_nexthop_new) remove init of parent - field is gone from struct vertex_nexthop. (ospf_canonical_nexthops_free) Remove the canonical vertex_nexthop memory objects. These are the vertex_nexthops attached to the first level of router vertices from the root. (vertex_parent_new) new function, create a vertex_parent. (vertex_parent_free) ditto, but free it. (ospf_vertex_new) Update to match changes to struct vertex. (ospf_vertex_free) Recursively free a struct vertex and its children. The parent list is used as a reference count. vertex_nexthops must be free seperately, if required. (ospf_vertex_dump) update to match struct vertex changes. Print out backlink of parents too. (ospf_vertex_add_parent) ditto. (ospf_lsa_has_link) update comment. (ospf_nexthop_add_unique) removed, not needed anymore. (ospf_nexthop_merge) ditto. (ospf_spf_consider_nexthop) renamed to ospf_spf_add_parent. Simplified to just create vertex_parent and add it. (ospf_spf_flush_parents) new function, flush out the parent list. (ospf_nexthop_calculation) Take the relevant route_lsa_link as an argument, which simplifies things and removes the need for the hack in ospf_nexthop_add_unique - ospf_spf_next already knew exactly which link the cost calculated was for. Update to match struct vertex changes too. (ospf_spf_next) Don't create a vertex for W unnecessarily, if it's there's a vertex already created for W, use it, and hence there's no need to free it either. Update some manipulation/comparisons of distance to match. Flush the parent list if a lower cost path is found. (ospf_spf_route_free) unused, removed. (ospf_spf_dump) match the struct vertex changes, and dump the ifname if possible. (ospf_spf_calculate) At end of SPF, free the canonical nexthops and call ospf_vertex_free on the root vertex to free the entire tree. * ospf_interface.c: (ospf_vl_set_params) match struct vertex changes. * ospf_route.c: (ospf_intra_route_add) ditto (ospf_route_copy_nexthops_from_vertex) ditto * memtypes.c: (memory_list_ospf) Add MTYPE_OSPF_VERTEX_PARENT.

* ospfd/ospf_vty.c: forece default route LSA to be re_issued whenever cost is changed ( [no] ip ospf area XXX default-cost YYY) Support ignore-mtu option * ospfd/ospfd.h: define OSPF_MTU_IGNORE_DEFAULT * ospfd/ospf_packet.c: support ignore-mtu option * ospfd/ospf_interface.h: field added for skipping MTU check * ospfd/ospf_interface.c: fix memory leak in ospf_crypt_key_delete() Set mtu_ignore field to default value * ospfd/ospf_abr.[ch]: export ospf_abr_announce_network_to_area() * ospfd/ospf_ism.h: add MACRO to convert internal ISM status into SNMP correct values * ospfd/ospf_snmp.c: add sanity check on LSA type in lsdb_lookup_next() convert OSPFIFSTATE internal status into SNMP values

* ospf_interface.c: (ospf_if_table_lookup) Fix a serious bug a less serious one. 1: this function is supposed to lookup entries in the oifs ospf_interface route_table and return either an existing oi or NULL to indicate not found, its caller depends on this, yet this function uses route_node_get which /always/ returns a route_node - one is created if none exists. Use route_node_lookup instead. This should fix root cause of the reports of the (ospf_add_to_if) assert being hit. 2: oi's are inserted into this table with prefixlength set to /32 (indeed, it should be a hash table, not a route_table), however prefixlength to lookup was not changed, if no valid entry can be inserted other than /32, then nothng but /32 should be looked up. This possibly only worked by fluke.. Fix confirmed by 2 reporters (one list, one IRC), definitely a backport candidate once it has been incubated in HEAD for a while. Thanks to Patrick Friedel and Ivan Warren for testing.

* (general) extern and static qualifiers added. unspecified arguments in definitions fixed, typically they should be 'void'. function casts added for callbacks. Guards added to headers which lacked them. Proper headers included rather than relying on incomplete definitions. gcc noreturn function attribute where appropriate. * ospf_opaque.c: remove the private definition of ospf_lsa's ospf_lsa_refresh_delay. * ospf_lsa.h: export ospf_lsa_refresh_delay * ospf_packet.c: (ospf_make_md5_digest) make *auth_key const, correct thing to do - removes need for the casts later. * ospf_vty.c: Use vty.h's VTY_GET_INTEGER rather than ospf_vty's home-brewed versions, shuts up several warnings. * ospf_vty.h: remove VTY_GET_UINT32. VTY_GET_IPV4_ADDRESS and VTY_GET_IPV4_PREFIX moved to lib/vty.h. * ospf_zebra.c: (ospf_distribute_list_update_timer) hacky overloading of the THREAD_ARG pointer should at least use uintptr_t.
2005-04-072005-04-07 Paul Jakma <paul.jakma@sun.com>paul
* (global): Fix up list loops to match changes in lib/linklist, and some basic auditing of usage. * configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES * HACKING: Add notes about deprecating interfaces and commands. * lib/linklist.h: Add usage comments. Rename getdata macro to listgetdata. Rename nextnode to listnextnode and fix its odd behaviour to be less dangerous. Make listgetdata macro assert node is not null, NULL list entries should be bug condition. ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use with for loop, Suggested by Jim Carlson of Sun. Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the "safety" of previous macro. LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to distinguish from the similarly named functions, and reflect their effect better. Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section with the old defines which were modified above, for backwards compatibility - guarded to prevent Quagga using it.. * lib/linklist.c: fix up for linklist.h changes. * ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single scan of the area list, rather than scanning all areas first for INTER_ROUTER and then again for INTER_NETWORK. According to 16.2, the scan should be area specific anyway, and further ospf6d does not seem to implement 16.3 anyway.

* if.h: (if_lookup_by_name_len, if_get_by_name_len) New functions. * if.c: (if_lookup_by_name_len, if_get_by_name_len) New functions. (if_get_by_name) Tighten up code. (interface) Use new function if_get_by_name_len. * zclient.c: (zebra_interface_add_read) Use new if_get_by_name_len function. (zebra_interface_state_read) Use new if_lookup_by_name_len function. * kernel_socket.c: (ifm_read) Use new if_lookup_by_name_len function to save a memcpy. * if_ioctl_solaris.c: (interface_list_ioctl) Fix subtle bug with new if_get_by_name_len function. * ospf_interface.c: (ospf_vl_new) Use strnlen to fix call to if_create.
2005-03-292005-03-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* 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.
2005-02-082005-02-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* 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.

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.

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));
