2006-07-11[ospfd] record timestamp and event of last NSM state change for neighbourPaul Jakma
2006-07-10 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (ospf_nsm_event) Record state change timestamp and event in nbr struct. * ospf_neighbor.h: (struct ospf_neighbor) Add fields to record timestamp of last NSM change and event. * ospf_vty.c: (show_ip_ospf_neighbor_detail_sub) Print last state change timestamp and event, if available.
2006-06-30[ospfd] Fix "show ip ospf neighbor A.B.C.D" to show all matchesAndrew J. Schorr
2006-06-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_vty.c: (show_ip_ospf_neighbor_id) Should show all instances of that neighbor (since it may appear on multiple interfaces) instead of bailing out after showing the first match.
2006-06-29[ospfd] Implement new ospf router subcommand "log-adjacency-changes [detail]"Andrew J. Schorr
2006-06-28 Erik Muller <erikm@internap.com> * ospfd.h: Define 2 new struct ospf config flags: OSPF_LOG_ADJACENCY_CHANGES and OSPF_LOG_ADJACENCY_DETAIL * ospf_nsm.c (nsm_change_state): Log adjacency changes if requested. * ospf_vty.c (ospf_log_adjacency_changes): New command function to implement ospf subcommand "log-adjacency-changes [detail]". (no_ospf_log_adjacency_changes) Turn off log-adjacency-changes. (show_ip_ospf) Show whether adjacency changes are logged. (ospf_config_write) Add "log-adjacency-changes [detail]" to config. (ospf_vty_init) Add ospf_log_adjacency_changes and no_ospf_log_adjacency_changes. * ospfd.texi: Document new ospf router subcommand "log-adjacency-changes [detail]".
2006-06-27[ospfd] Replace redistribution strings with new route_types.h defines.Paul Jakma
2006-05-23 Paul Jakma <paul.jakma@sun.com> * ospf_vty.c: (general) Replace in-place route redistribution command and help strings with the new auto-generated defines from lib/route_types.h
2006-06-18[ospfd] Fix ospf passive-interface subcommand to create interface if necessaryAndrew J. Schorr
2006-06-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_vty.c: ({no_,}ospf_passive_interface) Replace if_lookup_by_name with a call to if_get_by_name -- if the interface does not exist already, it should be created. And remove the obsolete warning message.
2006-06-15[ospfd] Fix multicast membership drop bugPaul Jakma
2006-06-15 Paul Jakma <paul.jakma@sun.com> * Reported by Milan Koci * ospf_interface.h: (struct ospf_if_info) Add reference counts for multicast group memberships. Add various macros to help manipulate/check membership state. * ospf_interface.c: (ospf_if_set_multicast) Maintain the ospf_if_info reference counts, and only actually drop memberships if it hits 0, to avoid losing membership when OSPF is disabled on an interface with multiple active OSPF interfaces. * ospf_packet.c: (ospf_{hello,read}) Use the new macros to check/set multicast membership. * ospf_vty.c: (show_ip_ospf_interface_sub) ditto.
2006-05-11[ospfd] Check NULL result from ospf_area_lookup_by_area_id, CID #69Paul Jakma
2006-05-11 Paul Jakma <paul.jakma@sun.com> * ospf_vty.c: (no_ospf_area_filter_list) Check NULL result from ospf_area_lookup_by_area_id, fixes Coverity CID #69
2006-05-11[ospfd] Fix missing check for ospf_lookup NULL return, CID #70Paul Jakma
2006-05-11 Paul Jakma <paul.jakma@sun.com> * ospf_vty.c: (general) Audit ospf_lookup calls in commands, ensure check for NULL result, make vty messages consistent. (show_ip_ospf_interface) Missing NULL check on ospf_lookup result, fixes Coverity CID #70.
2006-05-04[ospfd] Fix SPF of virtual-linksPaul Jakma
2006-04-24 Paul Jakma <paul.jakma@sun.com> * (general) More Virtual-link fixes, again with much help in testing / debug from Juergen Kammer. Primarily in SPF. * ospf_spf.h: Add guard. ospf_interface.h will include this header. * ospf_interface.h: Modify ospf_vl_lookup definition to take struct ospf as argument, so as to allow for NULL area argument. (struct ospf_vl_data) Remove out_oi, instead add a struct vertex_nexthop, to use as initial nexthop for backbone paths through a vlink. * ospf_interface.c: (ospf_vl_lookup) Modified to allow NULL area to be passed to indicate "any" (first) area. Add extra debug. (ospf_vl_set_params) vl_oi -> nexthop. Add extra debug. (ospf_vl_up_check) Fix debug, inet_ntoa returns a static buffer.. * ospf_route.c: (ospf_intra_add_router) Vlinks dont go through backbone, don't bother checking. * ospf_spf.c: (static struct list vertex_list) Record vertices that will need to be freed. (cmp) Order network before router vertices, as required, wasn't implemented. (vertex_nexthop_free) Mild additional robustness check. (vertex_parent_free) Take void argument, as this function is passed as list deconstructor for vertex parent list. (ospf_vertex_new) More debug. Set deconstructor for parent list. Track allocated vertices on the vertex_list. (ospf_vertex_free) Get rid of the tricky recursive cleanup of vertices. Now frees only the given vertex. (ospf_vertex_add_parent) Fix assert. (ospf_nexthop_calculation) Fix calculation of nexthop for VLink vertices, lookup the vl_data and use its previously recorded nexthop information. (ospf_spf_calculate) Vertices are freed simply by deleting vertex_list nodes and letting ospf_vertex_free as deconstructor work per-node. (ospf_spf_calculate_timer) Trivial optimisation, leave backbone SPF calculation till last to reduce SPF churn on VLink updates. * ospf_vty.c: (ospf_find_vl_data) update call to ospf_vl_lookup (no_ospf_area_vlink_cmd) ditto. (show_ip_ospf_interface_sub) For Vlinks, the peer address is more interesting than the output interface.
2006-01-19[compiler] miscellaneous trivial compiler warning fixespaul
2006-01-19 Paul Jakma <paul.jakma@sun.com> * (general) various miscellaneous compiler warning fixes. Remove redundant break statements from switch clauses which return. return from main, not exit, cause it annoys SOS. Remove stray semi-colons which cause empty-statement warnings. * zebra/main.c: (sighup) remove private declaration of external function.
2006-01-10[ospfd] trim redundant stringspaul
2006-01-10 Paul Jakma <paul.jakma@sun.com> * ospf_vty.c: (config_write_ospf_distribute) trim down redundant strings.
2005-11-26[ospfd] rename graceful to deferred, fix a tiny compile warning.paul
2005-11-26 Paul Jakma <paul.jakma@sun.com> * (general) s/graceful/deferred/ in all files, the former term is confusing wrt OSPF Graceful-Restart. * ospfd.c: (ospf_deferred_shutdown_check) dont return a function which returns void. SOS complains about this. (ospf_finish)
2005-11-202005-11-20 Paul Jakma <paul.jakma@sun.com>paul
* ospfd.h: remove the OSPF_ROUTER_ID_UPDATE_DELAY define (struct ospf) remove the router_id timer thread. remove export of ospf_router_id_update_timer. * ospfd.c: (ospf_router_id_update) call ospf_if_update to poke interfaces into action after ID has been configured. (ospf_router_id_update_timer) removed. (ospf_finish_final) t_router_id_update timer is gone. (ospf_network_run) router-id update timer gone. call ospf_router_id_update directly if ID not configured. In the per-iface loop, don't ospf_if_up interfaces if ID is still not configured. The update function will call ospf_if_update anyway. (ospf_if_update) ID update timer is gone. Just return if no ID is set. * ospf_vty.c: (ospf_router_id) call ospf_router_id_update, no timer needed. * ospf_zebra.c: (ospf_router_id_update_zebra) call ospf_router_id_update directly, not via timer.
2005-11-16[ospfd] Standardize buffer sizes used for displaying timers.ajs
2005-11-16 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_dump.h: Define OSPF_TIME_DUMP_SIZE as appropriate buffer size for use with ospf_timer_dump and ospf_timeval_dump. * ospf_vty.c: Change all buffer sizes used with ospf_timer_dump and ospf_timeval_dump to have size OSPF_TIME_DUMP_SIZE. (show_ip_ospf_interface_sub) Fix possible buffer overflow in call to ospf_timer_dump.
2005-11-042005-11-04 Paul Jakma <paul.jakma@sun.com>paul
* ospf_{dump,spf,vty}.c: Oops, use the internal tv_sub function rather than unportable timersub.
2005-10-292005-10-29 Paul Jakma <paul.jakma@sun.com>paul
* (general) RFC3137 stub-router support * ospfd.h: Add OSPF_OUTPUT_COST_INFINITE define. (struct ospf_master) Add a OSPF_MASTER_SHUTDOWN flag for options, to allow shutdown to distinguish between complete shutdown and shutdown of a subset of ospf instances. (struct ospf) Add stub_router_{startup,shutdown_}time, configuration of startup and shutdown time for stub-router. Add t_graceful_shutdown struct thread, timer for graceful shutdown, if needed. (struct ospf_area) Add stub_router_state - run time state of stub-router for an area. Add flags for ADMIN, IS and WAS states. Add t_stub_router, timer thread to resend router-lsa for an area. * ospf_lsa.c: (ospf_link_cost) new simple function to spit out either the given lnks cost or infinite cost if stub-router is in effect. (lsa_link_{ptop,broadcast,virtuallink,ptomp}_set) use previous function for transit-links. (ospf_stub_router_timer) timer thread for end of startup stub router. Change state as required for the area and setup re-origination of router-lsa. (ospf_stub_router_check) Check/do whether stub-router should be enabled, and whether it requires timer to be setup. (ospf_router_lsa_new) call previous function at top. (ospf_router_lsa_originate) no external callers, made static. * ospf_lsa.h: (ospf_router_lsa_originate) removed. * ospf_main.c: (sigint) make static. remove call to exit, as ospf_terminate now deals with exiting. * ospf_route.c: (ospf_terminate) removed, now in ospfd.c. * ospf_vty.c: (show_ip_ospf_area) print out state of stub-router, if active. (show_ip_ospf) print out configuration of stub-router support, and details of graceful-shutdown if the timer is active. ((no)?ospf_max_metric_router_lsa_{admin,startup,shutdown}) new commands to (de-)?configure stub-router support. (config_write_stub_router) write out config of stub-router. (ospf_config_write) call previous. (ospf_vty_init) install the new stub-router commands. * ospfd.c: various functions made static. (ospf_new) Set defaults for stub-router. Graceful shutdown is made to default on, just to be adventerous. (ospf_graceful_shutdown_finish) new function, final part of shutdown. (ospf_graceful_shutdown_timer) timer thread wrapper for graceful-shutdown. (ospf_graceful_shutdown_check) check whether to setup timer for shutdown or proceed directly to final shutdown. (ospf_terminate) moved here from ospf_route.c, call ospf_finish for each instance. (ospf_finish) renamed to ospf_finish_final and made static. (ospf_finish) new function, exported wrapper around ospf_graceful_shutdown_check. (ospf_finish_final) complete shutdown of an instance. Add missing TIMER_OFF's of two timer threads. (ospf_area_free) opaque self lsa timer should be turned off.
2005-10-232005-10-23 Paul Jakma <paul.jakma@sun.com>paul
* ospf_vty.c: (show_ip_ospf) fix display of SPF timer if it has not yet been run.

2005-10-212005-10-21 Paul Jakma <paul.jakma@sun.com>paul
* (general) SPF millisecond resolution timer with adaptive, linear back-off holdtime. Prettification of ospf_timer_dump. * ospf_dump.c: (ospf_timeval_dump) new function. The guts of ospf_timer_dump, but made to be more dynamic in printing out the relative timeval, sliding the precision printed out according to the value. (ospf_timer_dump) guts moved to ospf_timeval_dump. * ospf_dump.h: export ospf_timeval_dump. * ospf_flood.c: (ospf_flood) remove gettimeofday, use the libzebra exported recent_time instead, as it's not terribly critical to have time exactly right - the dropped LSA will be retransmited to us if we don't ACK it. * ospf_packet.c: (ospf_ls_upd_timer) Ditto, but here we're not transmitting, just putting LSA back on update transmit list. * ospfd.h: delay and holdtimes should be unsigned. Add spf_max_holdtime and spf_hold_multiplier. Update default defines for delay and hold time to be in msec. (struct ospf) change the SPF timestamp to a struct timeval. Remove ospf_timers_spf_(un)?set. * ospfd.c: (ospf_timers_spf_{set,unset}) removed. (ospf_new) initialise spf_max_holdtime and spf_hold_multiplier * ospf_spf.c: (ospf_spf_calculate) SPF timestamp is a timeval now, update with gettimeofday. (ospf_spf_calculate_schedule) Change SPF timers to millisecond resolution. Make the holdtime be adaptive, with a linear increase in holdtime ever consecutive SPF run which occurs within holdtime of previous SPF, bounded by spf_max_holdtime. * ospf_vty.c: Update spf timers commands. (ospf_timers_spf_set) trivial helper. (ospf_timers_throttle_spf_cmd) new command to set SPF delay, initial hold and max hold times with millisecond resolution. (ospf_timers_spf_cmd) Deprecated. Accept the old values, convert to msec, truncate to new limits. (no_ospf_timers_throttle_spf_cmd) set timers to defaults. (no_ospf_timers_spf_cmd) deprecated form, same as previous. (show_ip_ospf_cmd) Display SPF parameters and times. (show_ip_ospf_neighbour_header) Centralise the 'sh ip os ne' header. (show_ip_ospf_neighbor_sub) Fix the field widths. Get rid of the multiple spaces which were making the lines even longer. (show_ip_ospf_neighbor_cmd) Use show_ip_ospf_neighbour_header (show_ip_ospf_neighbor_all_cmd) ditto and fix the field widths for NBMA neighbours. (show_ip_ospf_neighbor_int) Use header function. (show_ip_ospf_nbr_nbma_detail_sub) use sizeof for timebuf, local array - safer. (show_ip_ospf_neighbor_detail_sub) ditto (ospf_vty_init) install the new SPF throttle timer commands.
2005-10-212005-10-21 Paul Jakma <paul.jakma@sun.com>paul
* (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.

* zebra.h: Declare new functions zebra_route_string() and zebra_route_char(). * log.c: (zroute_lookup,zebra_route_string,zebra_route_char) New functions to map zebra route numbers to strings. * zebra_vty.c: (route_type_str) Remove obsolete function: use new library function zebra_route_string() instead. Note that there are a few differences: for IPv6 routes, we now get "ripng" and "ospf6" instead of the old behavior ("rip" and "ospf"). (route_type_char) Remove obsolete function: ues new library function zebra_route_char() instead. Note that there is one difference: the old function returned 'S' for a ZEBRA_ROUTE_SYSTEM route, whereas the new one returns 'X'. (vty_show_ip_route_detail,vty_show_ipv6_route_detail) Replace route_type_str() with zebra_route_string(). (vty_show_ip_route,vty_show_ipv6_route) Replace route_type_char() with zebra_route_char(). * bgp_vty.c: (bgp_config_write_redistribute) Use new library function zebra_route_string instead of a local hard-coded table. * ospf6_asbr.c: Remove local hard-coded tables zroute_name and zroute_abname. Change the ZROUTE_NAME macro to use new library function zebra_route_string(). Remove the ZROUTE_ABNAME macro. (ospf6_asbr_external_route_show): Replace ZROUTE_ABNAME() with a call to zebra_route_char(), and be sure to fix the format string, since we now have a char instead of a char *. * ospf6_zebra.c: Remove local hard-coded tables zebra_route_name and zebra_route_abname. Note that the zebra_route_name[] table contained mixed-case strings, whereas the zebra_route_string() function returns lower-case strings. (ospf6_zebra_read_ipv6): Change debug message to use new library function zebra_route_string() instead of zebra_route_name[]. (show_zebra): Use new library function zebra_route_string() instead of zebra_route_name[]. * ospf_dump.c: Remove local hard-coded table ospf_redistributed_proto. (ospf_redist_string) New function implemented using new library function zebra_route_string(). Note that there are a few differences in the output that will result: the new function returns strings that are lower-case, whereas the old table was mixed case. Also, the old table mapped ZEBRA_ROUTE_OSPF6 to "OSPFv3", whereas the new function returns "ospf6". * ospfd.h: Remove extern struct message ospf_redistributed_proto[], and add extern const char *ospf_redist_string(u_int route_type) instead. * ospf_asbr.c: (ospf_external_info_add) In two messages, use ospf_redist_string instead of LOOKUP(ospf_redistributed_proto). * ospf_vty.c: Remove local hard-coded table distribute_str. (config_write_ospf_redistribute,config_write_ospf_distribute): Use new library function zebra_route_string() instead of distribute_str[]. * ospf_zebra.c: (ospf_redistribute_set,ospf_redistribute_unset, ospf_redistribute_default_set,ospf_redistribute_check) In debug messages, use ospf_redist_string() instead of LOOKUP(ospf_redistributed_proto). * rip_zebra.c: (config_write_rip_redistribute): Remove local hard-coded table str[]. Replace str[] with calls to new library function zebra_route_string(). * ripd.c: Remove local hard-coded table route_info[]. (show_ip_rip) Replace uses of str[] with calls to new library functions zebra_route_char and zebra_route_string. * ripng_zebra.c: (ripng_redistribute_write) Remove local hard-coded table str[]. Replace str[i] with new library function zebra_route_string(i). * ripngd.c: Remove local hard-coded table route_info[]. (show_ipv6_ripng) Use new library function zebra_route_char() instead of table route_info[].

* ospfd.h: add OSPF_ABR_DEFAULT for convenience, make OSPF_ABR_CISCO be the default ABR type. * ospfd.c: (ospf_new) initialise abr_type to OSPF_ABR_DEFAULT * ospf_vty.c: (no_ospf_abr_type_cmd) add standard as a negatable abr_type. default abr_type should be OSPF_ABR_DEFAULT. (ospf_config_write) test whether default abr_type against OSPF_ABR_DEFAULT, rather than any specific ABR_TYPE.
2005-05-062005-05-06 Paul Jakma <paul.jakma@sun.com>paul
* (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.

Fix problems when netlink interfaces are renamed (same ifindex used for a new interface). Start cleaning up some problems with the way interface names are handled. * interface.c: (if_new_intern_ifindex) Remove obsolete function. (if_delete_update) After distributing the interface deletion message, set ifp->ifindex to IFINDEX_INTERNAL. (if_dump_vty) Detect pseudo interface by checking if ifp->ifindex is IFINDEX_INTERNAL. (zebra_interface) Check return code from interface_cmd.func. Do not set internal ifindex values to if_new_intern_ifindex(), since we now use IFINDEX_INTERNAL for all pseudo interfaces. * kernel_socket.c: (ifm_read) Fix code and comments to reflect that all internal interfaces now have ifp->ifindex set to IFINDEX_INTERNAL. * rt_netlink.c: (set_ifindex) New function used to update ifp->ifindex. Detects interface rename events by checking if that ifindex is already being used. If it is, delete the old interface before assigning the ifindex to the new interface. (netlink_interface, netlink_link_change) Call set_ifindex to update the ifindex. * if.h: Remove define for IFINDEX_INTERNBASE and add define IFINDEX_INTERNAL 0, since all internal (i.e. non-kernel) pseudo- interfaces should have ifindex set to 0. (if_new) Remove function. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (ifname2ifindex) New function. * if.c: (if_new) Remove function (absorb into if_create). (if_create) Replace function if_new with call to calloc. Set ifp->ifindex to IFINDEX_INTERNAL. Fix off-by-one error in assert to check length of interface name. Add error message if interface with this name already exists. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (if_delete) Implement with help of if_delete_retain. (ifindex2ifname) Reimplement using if_lookup_by_index. (ifname2ifindex) New function to complement ifindex2ifname. (interface) The interface command should check the name length and fail with a warning message if it is too long. (no_interface) Fix spelling in warning message. (if_nametoindex) Reimplement using if_lookup_by_name. (if_indextoname, ifaddr_ipv4_lookup) Reimplement using if_lookup_by_index. * bgp_zebra.c: (bgp_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * isis_zebra.c: (isis_zebra_if_del) Call if_delete_retain instead of if_delete, since it is generally not safe to remove interface structures. After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Tighten up code. * ospf6_zebra.c: (ospf6_zebra_if_del) Previously, this whole function was commented out. But this is not safe: we should at least update the ifindex when the interface is deleted. So the new version updates the interface status and sets ifp->ifindex to IFINDEX_INTERNAL. (ospf6_zebra_route_update) Use if_indextoname properly. * ospf_vty.c: (show_ip_ospf_interface_sub) Show ifindex and interface flags to help with debugging. * ospf_zebra.c: (ospf_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Make function static. Tighten up code. * rip_interface.c: (rip_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * ripng_interface.c: (ripng_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL.

* ospf_vty.c (show_ip_ospf_interface_sub): Display interface MTU and bandwidth; this is useful for debugging problems. Also, the function should be static.

* 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.

* (global) Const char update and signed/unsigned fixes. * (various headers) size defines should be unsigned. * ospf_interface.h: remove duplicated defines, include the authoritative header - though, these defines should probably be moved to a dedicated header, or ospfd.h. * ospf_lsa.h: (struct lsa) ls_seqnum should be unsigned. * ospf_packet.c: (ospf_write) cast result of shift to unsigned.
