* ospf_dump.c: (ospf_timeval_dump) fix ms adjustment, thanks to Andrew Schorr. * ospf_vty.c: (ospf_config_write) fix write out of spf timers configuration.
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.

* (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.
2005-10-112005-10-11 Paul Jakma <paul.jakma@sun.com>paul
* ospf_api.c: sign warnings. * ospf_apiserver.c: sign warning and convert all the struct in_addr initialisations so as not to make assumptions about how this struct is organised, initialise the s_addr member explicitely. * ospf_packet.c: Add const qualifier to auth_key.
2005-10-062005-10-06 Alain Ritoux <alain.ritoux@6wind.com>vincent
* ospf_snmp.c: Avoid mixing interface and ospf_interface objects which now allows snmpwalk to work with ospfIfTable and also with ospfIfMetricTable
2005-10-012005-10-01 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* 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[].

2005-08-05 * ospf_zebra.c: Don't assert/stop before type == ZEBRA_ROUTE_MAX ifhasso
dealing with routemaps. There is ospf->route_map[ZEBRA_ROUTE_MAX] for default-information. Fixes bugzilla #208. [backport candidate]
2005-07-262005-07-26 Paul Jakma <paul.jakma@sun.com>paul
* ospf_abr.c: (ospf_abr_announce_network_to_area) SET_FLAG should be on lsa not old, which may be freed for one thing, obviously.
2005-07-122005-07-12 Paul Jakma <paul.jakma@sun.com>paul

2005-06-20 * ospf_nsm.c: Make database exchange for NSSA database work.hasso
[backport candidate]
2005-06-132005-06-13 Paul Jakma <paul.jakma@sun.com>paul
* ospf_spf.c: Try get more information on a SEGV under ospf_spf_vertex_add_parent. (ospf_vertex_free) NULL out the child and nexthop lists (ospf_vertex_add_parent) nexthop and child can not be NULL vertex_nexthop's parent->child list can not be NULL (ospf_spf_next) w and cw are per-loop iteration variables, move declarations into loop body.
2005-06-07 * ospf_apiserver.c: Fix obvious error in notifying clients about ISMhasso
changes - oi->ifp->status doesn't give to us info about ISM, oi->state does. [backport candidate]
2005-06-012005-06-01 Akihiro Mizutani <mizutani@net-chef.net>paul
* ospf_ism.c (ospf_elect_bdr/ospf_elect_dr): Fix DR election bug.
2005-05-262005-05-26 Paul Jakma <paul.jakma@sun.com>paul

2005-05-182005-05-19 Paul Jakma <paul.jakma@sun.com>paul
* 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.
2005-05-112005-05-11 Paul Jakma <paul.jakma@sun.com>paul
* (general) Fix memory leaks in opaque AS-scope LSAs, reported and with much debugging done by by scott collins <scollins@agile.tv>. (possible backport candidate?) * ospf_lsa.c: (ospf_discard_from_db) dont call ospf_ase_unregister_external_lsa for opaque-lsa's, opaques are never registered with ase in the first place. * ospf_packet.c: (general) Disabuse opaque related code of its tendency to try gather up things into temporary lists. (ospf_ls_upd) remove the temporary lists opaque uses, call opaque functions inline, just like all other types. (ospf_ls_ack) ditto. (ospf_recv_packet) fixup sign warning. * ospf_opaque.c: (general) fix the unneeded use of lists, and untwist some of the logic. (ospf_opaque_self_originated_lsa_received) take a single LSA as argument, not a list of them. Remove the list loop. Logic otherwise unchanged. (ospf_opaque_ls_ack_received) Mostly ditto. But untwist the logic, move the actions up into the switch block, remove the goto's and sanitise the logic near the end a bit. * ospf_opaque.h: Adjust definitions of aforementioned functions in ospf_opaque.c to match.
2005-05-072005-05-07 Yar Tikhiy <yar@comp.chem.msu.su>paul
* configure.ac: Check for OSes which support passing ifindex in struct ip_mreq. * lib/sockopt.c: Add support for BSD style ifindex in ip_mreq. * ospfd/ospf_network.c: Log ifindex on multicast membership leave/join events.
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.
2005-04-152005-04-15 Zhipeng Gong <zpgong@cdc.3upsystems.com>paul
* ospf_abr.c: (ospf_abr_announce_network_to_area) dont forget to approve LSAs for the case where metric has changed, lsa gets flushed otherwise. (backport candidate).
2005-04-112005-04-11 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
Implement non-blocking zclient I/O with buffering. * zclient.h (struct zclient): Add two fields to support non-blocking I/O: struct buffer *wb, and struct thread *t_write. (zclient_free): Remove function. (zebra_redistribute_send): Change 2nd arg from socket fd to struct zclient * (needed to support non-blocking I/O and buffering). (zclient_send_message): New function to send an arbitrary message with non-blocking I/O. * zclient.c (zclient_new): Create write buffer. (zclient_free): Remove unused function. (zclient_stop): Must cancel new t_write thread. Also, reset all buffers: ibuf, obuf, and wb. (zclient_failed): New helper function for typical error handling. (zclient_flush_data): New thread to flush queued data. (zclient_send_message): New function to send the message in zclient->obuf to zebra using non-blocking I/O and buffering. (zebra_message_send, zapi_ipv4_route, zapi_ipv6_route): Use new zclient_send_message function instead of calling writen. (zclient_start): Set socket non-blocking. Also, change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. (zebra_redistribute_send): Change 2nd arg to struct zclient *. Can now use zclient->obuf to assemble the message instead of allocating a temporary stream. And call zclient_send_message to send the message instead of writen. (zclient_read): Convert to support non-blocking I/O by using stream_read_try instead of deprecated stream_read. (zclient_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf6_zebra.c (ospf6_zebra_redistribute, ospf6_zebra_no_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf_zebra.c (ospf_zebra_add): Call zclient_send_message instead of writen. * rip_zebra.c (rip_redistribute_set, rip_redistribute_unset, rip_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ripng_zebra.c (ripng_redistribute_unset, ripng_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * bgp_zebra.c (bgp_redistribute_set, bgp_redistribute_unset): The 2nd arg to zebra_redistribute_send is now zclient instead of zclient->sock. * isis_zebra.h (isis_zebra_finish): Remove declaration of unused function. * isis_zebra.c (isis_zebra_route_add_ipv4): Call zclient_send_message to send the message to zebra instead of calling writen directly, since zclient_send_message understands non-blocking I/O and will manage the buffer queue appropriately. (isis_zebra_finish): Remove unused function, particularly since the zclient_free function has been removed.

2005-04-022005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
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_dump.c: (show_debugging_ospf) Show if ospf event debugging is turned on. [backport candidate]
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.
2005-03-292005-03-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* ospf_packet.c: (ospf_write_frags) Enhance error message to show MTU. Also make function static. (ospf_write) Enhance error message to show interface name and MTU. Also make function static.
2005-03-292005-03-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* 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.
2005-03-27 * ospf_snmp.c: Don't crash in snmp query if ospf instance doesn'thasso
exist at all. [backport candidate]

* ospf_lsa.c: (ospf_lsa_refresh_walker) If the system clock jumps backward, then current time may be less than ospf->lsa_refresher_started. This was causing invalid values for ospf->lsa_refresh_queue.index resulting in infinite loops. Problem fixed by casting the expression to unsigned before taking the modulus. [backport candidate]
2005-02-232005-02-23 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* ospfd.h: Add new field struct stream *ibuf to struct ospf. * ospfd.c: (ospf_new) Check return code from ospf_sock_init. Allocate ibuf using stream_new(OSPF_MAX_PACKET_SIZE+1). (ospf_finish) Call stream_free(ospf->ibuf. * ospf_packet.c: (ospf_read) Call stream_reset(ospf->ibuf) and then pass it to ospf_recv_packet for use in receiving the packet (instead of allocating a new stream for each packet received). Eliminate all calls to stream_free(ibuf). (ospf_recv_packet) The struct stream *ibuf is now passed in as an argument. No need to use recvfrom to peek at the packet header (to see how big it is), just use ospf->ibuf which is always large enough (this eliminates a system call to recvfrom). Therefore, no need to allocate a stream just for this packet, and no need to free it when done.
2005-02-23 * ospf_lsa.h: New flag to the LSA structure for the SPF calculation.hasso
* ospf_lsdb.h: Export ospf_lsdb_clean_stat() function. * ospf_spf.h: Add link to the LSA stat structure into vertex. * ospf_spf.c: New functions cmp() and update_stat() to manage candidates. Remove ospf_spf_has_vertex(), ospf_vertex_lookup(), ospf_install_candidate() and ospf_spf_register() functions not needed any more. Update ospf_vertex_new(), ospf_spf_next() and ospf_spf_calculate() functions to use pqueue instead of linked list.
2005-02-21 * ospf_ase.c: Don't show messages related to the ase calculations ifhasso
we are not debugging.
2005-02-19 * ospf_api.h: char isn't always signed, but it has to be it here.hasso

Schorr <ajschorr@alumni.princeton.edu> * ospf_packet.c: (ospf_write) If sendmsg fails, give more info in the error message. 2005-02-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_interface.h: Reduce structure padding by putting new u_char field multicast_memberships in a better spot (grouped with other u_char fields type and state). 2005-02-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * 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. 2005-02-08 Paul Jakma <paul@dishone.st> * ospf_packet.c: (various) Remove unneeded stream_set_putp abuse. 2005-02-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_packet.c: (ospf_read) Fix bug: must check for state ISM_Down, not for event ISM_InterfaceDown.

(ospf_packet_authspace): Factor out calculation of size required for authentication. (ospf_make_db_desc): Use ospf_max_packet, not OSPF_MAX_PACKET. Don't confuse readers that there is a macro. 2004-12-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_network.c: Improve all setsockopt error messages to give detailed information on the arguments. 2004-12-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_packet.c: (ospf_db_desc) Reduce severity of "Negotiation done" messages from LOG_WARNING to LOG_INFO, since this seems to be normal. 2004-12-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_packet.c: (ospf_read) Always look up the interface if ospf_recv_packet returns NULL ifp, since some platforms such as Solaris 8 appear to support ifindex retrieval but don't. 2004-12-22 Hasso Tepper <hasso at quagga.net> * ospf_dump.c: Show debug configuration in vtysh. * ospf_vty.c: Fix "show ip ospf" output. Router can't be elected in any case if it's configured as "translate-never". * ospf_lsdb.[ch]: New function to calculate sum of checksums. * ospf_vty.c: Bugfix to show really number of AS external LSAs, not number of all LSAs with AS scope, this includes opaque as LSAs as well, show this number separately.

Schorr <ajschorr@alumni.princeton.edu> * ospf_packet.c: (ospf_db_desc_proc) Fix spelling of packet in warning message and in comment. (ospf_db_desc) Warning message that a packet is being discarded should give the router id of the packet source. Fix spelling of packet in two warning messages. (ospf_ls_req) Warning message that a link state request is being discarded should give the router id of the neighbor that sent it. 2004-11-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_main.c: Remove #include "debug.h" (was not being used, and lib/debug.h has now been deleted). 2004-11-25 Hasso Tepper <hasso at quagga.net> * ospf_main.c: Make group to run as configurable. 2004-11-15 Greg Troxel <gdt@fnord.ir.bbn.com> * ospf_packet.c (ospf_recv_packet): Assume CMSG_SPACE is present and works (lib/zebra.h provides if OS doesn't). 2004-11-15 Paul Jakma <paul@dishone.st> * ospf_{apiserver,te}.c: ospf_lsa_free's should be ospf_lsa_unlock. 2004-11-12 Paul Jakma <paul@dishone.st> * ospf_ia.c: (process_summary_lsa) Only an ABR has any reason to ignore stub area summary default.

Add convenience pointer to msg->msg_iov[1], and use this, fixing the unfortunate borkenness introduced in moving of this code to a function. (ospf_write) remove iovp and fix up call to previous. (ospf_ls_upd_packet_new) cast size to long int - unfortunately glibc's size_t format modifier is not portable. 2004-10-31 Paul Jakma <paul@dishone.st> * ospf_packet.c: (ospf_write_frags) Add debug output (ospf_write) set type early, so we can pass it to ospf_write_frags. (ospf_ls_upd_packet_new) print size in debug output when too large packet is encountered. * ospf_zebra.c: (ospf_distribute_list_update_timer) Ugly misuse of THREAD_ARG to store an integer, but it should at least use same same type to retrieve the value. Assert value is sane. 2004-10-22 Paul Jakma <paul@dishone.st> * ospf_network.c: (ospf_sock_init) call neutral setsock_ifindex() function. * ospf_packet.c: (ospf_read) manually look up ifindex if system could not have returned one, eg openbsd, thanks to Rivo Nurges for highlighting problem and fix.

(ospf_recv_packet) ip_len is needed for old OpenBSD fixup. (ospf_read) sockopt_iphdrincl_swab_systoh ip header as soon as we have it. * (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. 2004-10-08 Hasso Tepper <hasso at quagga.net> * *.[c|h]: Fix compiler warnings: make some strings const, signed -> unsigned, remove unused variables etc. 2004-10-07 Greg Troxel <gdt@claude.ir.bbn.com> * ospf_apiserver.c (ospf_apiserver_unregister_opaque_type): Don't use of variable names 'node' and 'nextnode' to avoid possible conflict with list macros.

(ospf_swab_iph_toh) the inverse. (ospf_write) Add support for IP fragmentation, will only work on linux though, other kernels make it impossible. get rid of the magic 4 constant. (ospf_make_ls_upd) Bound check to end of stream, not to interface mtu. (ospf_ls_upd_packet_new) New function, allocate upd packet taking oversized LSAs into account. (ospf_ls_upd_queue_send) use ospf_ls_upd_packet_new to allocate, rather than statically allocating mtu sized packet buffer, which actually was wrong - it didnt take ip header into account, which should not be included in packet buffer. (ospf_ls_upd_send_queue_event) minor tweaks and remove TODO comment. 2004-08-31 David Wiggins <dwiggins@bbn.com> * ospf_spf.c (ospf_spf_calculate): Many more comments and debug print statements.

Fixes Bugzilla #108. 2004-08-27 David Wiggins <dwiggins@bbn.com> * ospf_spf.c (ospf_nexthop_calculation): Initialize address family in on-stack struct prefix_ipv4. Fixes point-to-multipoint SPF calculation. 2004-08-26 Greg Troxel <gdt@fnord.ir.bbn.com> * ospf_packet.c (ospf_recv_packet): adjust size declaration of buffer used to get interface index so that it compiles on other than Linux and includes the required alignment space. Probably this was only working on sparc/sparc64 because most of sockaddr_dl was not being written. 2004-08-19 Paul Jakma <paul@dishone.st> * ospf_packet.c: update to match sockopt renames. 2004-08-04 Paul Jakma <paul@dishone.st> * ospf_spf.c: (ospf_spf_consider_nexthop) Add comment about issue.
