2007-09-18 Denis Ovsienko * ospf_network.c: (ospf_adjust_sndbuflen) Don't complain about getting more buffer space, than requested. * ospfd.[ch]: (ospf_new) Abandon OSPF_SNDBUFLEN_DEFAULT and consider OS's initial buffer size instead. * ospf_interface.c: (ospf_if_up) Fix missing argument. 2007-08-21 Denis Ovsienko * ospfd.h: Extend struct ospf with maxsndbuflen field and define its default value. * ospfd.c: (ospf_new) init maxsndbuflen * ospf_interface.c: (ospf_if_up) Call ospf_adjust_sndbuflen() for each regular interface being brought up. * ospf_network.[ch]: (ospf_adjust_sndbuflen) New function makes sure ospf socket sending buffer is large enough to cover the biggest interface MTU we have seen ever. * ospf_packet.c: (ospf_write) Use maxsndbuflen to decide on the biggest amount of data we are going to send at once. 2007-08-07 Paul Jakma * ospf_spf.c: (ospf_spf_next) Finish off the explanatory comment made in previous commit 2007-08-07 Atis Elsts * ospf_spf.c: (ospf_spf_next) Sort heap in correct direction after vertex cost is changed, thus fixing incorrect SPF calculation on certain topologies. 2007-08-06 Paul Jakma * ospf_lsa.c: (router_lsa_flags) Bug #331, NSSA regression caused caused ASBRs to not advertise E-bit into NSSA areas. 2007-05-09 Milan Kocian * ospf_vty.c: Fix commands: 'ip ospf authentication A.B.C.D', 'no ip ospf authentication A.B.C.D', 'no ip ospf authentication-key A.B.C.D'. Simply fix argv's indexes and argc check in DEFUN functions. 2007-05-07 Paul Jakma * ospf_spf.c: (ospf_vertex_new) Dont init vertices to infinity, just let 0 be a special case. (ospf_spf_add_parent) 0 distance candidate vertex is special, cost still to be initialised - asserting that new distance is <= existing only makes sense where w already has a cost. (ospf_spf_next) Infinite cost links should not be followed, bar those of the root. 2007-04-30 Andrew J. Schorr * ospfd.c: (ospf_network_match_iface) Comment out COMPATIBILITY_MODE. Going forward, the ospf "network" command will use a simple test: does the network command prefix contain the connected (destination) prefix of the interface? 2007-04-21 Andrew J. Schorr * ospf_interface.c: (ospf_if_set_multicast) Fix bug: was testing interface passive status improperly in light of the recent 'passive-interface default' patch. Now need to test OSPF_IF_PASSIVE_STATUS(oi) instead of OSPF_IF_PARAM(oi, passive_interface). 2007-03-23 Paul Jakma * ospf_spf.c: (various) Add more debug statements. (ospf_nexthop_calculation) Fix silly regression causing ospfd to fail to calculate paths past networks not attached to root vertex, introduced with bug #330 fixes. 2007-03-14 Andrew J. Schorr * ospf_snmp.c: (ospf_snmp_neighbor_state) New function to map internal quagga neighbor states to SNMP standard values. (ospfNbrEntry) Call new ospf_snmp_neighbor_state function. 2007-03-14 Andrew J. Schorr * ospf_zebra.c: (ospf_zebra_add, ospf_zebra_delete) Fix bug where inet_ntoa was used twice in the same debug message, which doesn't work because there's a single shared buffer for the returned string. The fix is to use inet_ntop. 2007-02-27 Andrew J. Schorr * ospfd.c: (ospf_terminate) Exit immediately if ospf is not actually running (e.g. the config file was empty). Fixes bug where SIGTERM would not kill ospfd. 2007-02-26 Paul Jakma * ospf_spf.c: Fix regression introduced with bug #330 fix: The cost update added to ospf_spf_add_parent only handled PtP case, differing from same functionality in higher-level ospf_spf_next. Regression diagnosed by Anders Pedersen, mailnews+router-quagga-dev@news.cohaesio.com. (ospf_vertex_new) Initialise vertices to max-cost. (ospf_spf_init) Root vertex always creates with 0 cost. (ospf_spf_add_parent) Remove the buggy V->W cost calculating code, instead take the new distance as a parameter. (ospf_nexthop_calculation) Take distance as parameter, so it can be passed down to add_parent. (ospf_spf_next) Dont initialise candiate vertex distance, vertex_new does so already. Pass distance down to nexthop_calculation (see above). 2007-01-24 Paul Jakma * ospf_spf.c: Bug #330: Nexthop calculation sometimes may fail, and it needs to indicate this result to SPF. (ospf_spf_add_parent) Flush of parent list needs to be done here, for simplicity. (ospf_nexthop_calculation) Caller needs to know whether nexthop calculation succeeded. Every return statement must correctly indicate such. (ospf_spf_next) Queueing/prioritisation of vertices in SPF must take into account whether nexthop_calculation succeeded, or SPF may fail to find best paths. 2006-12-12 Andrew J. Schorr * ospf_interface.c: (ospf_if_is_configured, ospf_if_lookup_by_prefix, ospf_if_lookup_recv_if) Simplify logic using new CONNECTED_PREFIX macro. * ospf_lsa.c: (lsa_link_ptop_set) Using the new CONNECTED_PREFIX macro, both options collapse into the same code. * ospf_snmp.c: (ospf_snmp_if_update) Simplify logic using new CONNECTED_ID macro. (ospf_snmp_is_if_have_addr) Simplify logic using new CONNECTED_PREFIX macro. * ospf_vty.c: (show_ip_ospf_interface_sub) Use new CONNECTED_PEER macro instead of testing the IFF_POINTOPOINT flag. * ospfd.c: (ospf_network_match_iface) Use new CONNECTED_PEER macro instead of testing with if_is_pointopoint. And add commented-out code to implement alternative (in my opinion) more elegant behavior that has no special-case treatment for PtP addresses. (ospf_network_run) Use new CONNECTED_ID macro to simplify logic. 2006-12-04 Andrew J. Schorr * ospfd.c: (ospf_network_run) Remove an offending 'break' statement. Previously, after creating a single ospf_interface on a given network interface, the code would skip to the next interface without considering other connected addresses on the interface. After removing the 'break', we now consider all connected addresses. 2006-11-30 Andrew J. Schorr * ospf_zebra.c: (ospf_router_id_update_zebra, ospf_interface_address_add, ospf_interface_address_delete) If (IS_DEBUG_OSPF (zebra, ZEBRA_INTERFACE)) is enabled, then add a debug message about what Zebra is telling us. (ospf_zebra_add_discard) Add a debug message matching the one already in ospf_zebra_delete_discard. 2006-11-28 Andrew J. Schorr * ospf_vty.c: (ospf_passive_interface_default) Take additional 'newval' arg so we can update ospf->passive_interface_default inside this function. More importantly, we now call ospf_if_set_multicast on all ospf_interfaces. (ospf_passive_interface, no_ospf_passive_interface) Fix bug: for 'default' case, argv[0] is undefined, so we must test for (argc == 0) before using argv[0]. And since ospf_passive_interface_default now calls ospf_if_set_multicast as needed, we can just return after calling ospf_passive_interface_default. 2006-10-24 Andrew J. Schorr * ospf_zebra.c: (ospf_redistribute_default_set) Fix bug where a new value for ospf->default_originate was being ignored if a previous 'default-information originate' command had already been processed. 2006-10-22 Yar Tikhiy * (general) Add support for passive-interface default (with minor edits by Paul Jakma). * ospf_interface.h: Add OSPF_IF_PASSIVE_STATUS macro, looking at configured value, or the global 'default' value, as required. * ospf_interface.c: (ospf_if_new_hook) Leave passive unconfigured per default, allowing global 'default' to take effect for unconfigured interfaces. * ospf_packet.c: (various) use OSPF_IF_PASSIVE_STATUS * ospf_vty.c: (ospf_passive_interface_default) new function, unset passive from all interfaces if default is enabled, as the per-iface settings become redundant. (ospf_passive_interface_update) new func, update passive setting taking global default into account. ({no,}ospf_passive_interface_addr_cmd) Add support for 'default' variant of command. (show_ip_ospf_interface_sub) Update to take global default into account when printing passive status. (ospf_config_write) ditto. * ospfd.c: (ospf_new) set global passive-interface default. * ospfd.h: (struct ospf) Add field for global passive-interface. 2006-09-25 Andrew J. Schorr * ospf_packet.c: (ospf_packet_dup, ospf_make_md5_digest) Fix zlog_warn messages to eliminate compiler warnings. (ospf_hello) Improve warning messages to show why we are complaining. 2006-08-28 Andy Gay * ospf_packet.c: (ospf_make_db_desc) Assert added with More-bit fixes does not hold up with addition of Ogier DB-Exchange optimisation, which can empty the db-summary list in between sent DD packets. Remove assert, update More-bit always when in Exchange. 2006-08-27 J.J. Krabbendam * ospfd.c: (ospf_finish_final) default redistribute should be unset too, fixes bug where reconfiguring ospfd completely can no longer enable default redistribution. 2006-08-25 Paul Jakma * (general) Bug #134. Be more robust to backward time changes, use the newly added libzebra time functions. In most cases: recent_time -> recent_relative_time() gettimeofday -> quagga_gettime (QUAGGA_CLK_MONOTONIC, ..) time -> quagga_time. (ospf_make_md5_digest) time() call deliberately not changed. (ospf_external_lsa_refresh) remove useless gettimeofday, LSA tv_orig time was already set in ospf_lsa_new, called via ospf_external_lsa_new. 2006-08-04 Paul Jakma * ospf_lsdb.c: (ospf_lsdb_delete_entry) new function, consolidate exact same functionality replicated in other functions. (ospf_lsdb_add) Strip out code by using ospf_lsdb_delete_entry. (ospf_lsdb_delete) ditto. (ospf_lsdb_delete_all) ditto. 2006-08-03 Paul Jakma * ospf_packet.c: (ospf_make_db_desc) Unset the DD More bit after constructing the packet, if appropriate. (ospf_db_desc_proc) Speed up Exchange, slave should raise ExchangeDone earlier, as RFC mandates, by forming its reply before deciding whether both sides are done, avoids a needless round of empty DD packet exchanges at the end of Exchange, hence speeding up ExchangeDone. Implement draft-ogier-ospf-dbex-opt DB-exchange optimisation. (ospf_db_desc) use UNSET_FLAG macro. 2006-07-27 Andrew J. Schorr * ospfd.c: (ospf_router_id_update) Fix and document the algorithm for selecting the router ID: if there is not a statically configured ID, then stick to the most recent value to avoid disruptive changes. This should fix bug #288. 2006-07-26 Paul Jakma * 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. 2006-07-25 Paul Jakma * ospf_neigbor.h: (struct ospf_neighbor) Add some additional neighbour state statistics fields, timestamps for progressive and regressive state changes, and pointer to event string for the latter state change. * ospf_nsm.c: (nsm_notice_state_change) Update new state changs history as required. * ospf_vty.c: (show_ip_ospf_neighbor_detail_sub) Print out above new per-neighbour state change stats. 2006-07-10 Paul Jakma * ospf_nsm.c: (nsm_change_state) call nsm_clear_adj for all adjacency losses, hence removing need for nsm_reset_nbr. (nsm_reset_nbr) kill it, clear_adj in previous does fine. (nsm_kill_nbr,nsm_start) remove nsm_reset_nbr call. (ospf_nsm_event) Allow NSM function to be NULL, this along with removal of nsm_reset_nbr, allows a bunch of now useless functiosn to be removed. Remove some useless variables. (nsm_ignore) now useless, remove. (nsm_bad_ls_req) ditto (nsm_seq_number_mismatch) " (nsm_oneway_received) " (nsm_inactivity_timer) " (nsm_ll_down) " (NSM) replace removed action functions with NULL. (nsm_notice_state_changes) Move state change logging code to new func to declutter nsm_change_state and ospf_nsm_event. Log event with AdjChange, it's useful to know. (nsm_change_state) move adjchange and snmp logging to previous. (ospf_nsm_event) call nsm_notice_state_changes from here. Move the debug message to entry of function, so it gets out even if something goes wrong. 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. 2006-07-10 Andrew J. Schorr * ospf_packet.c: (ospf_hello) Improve NetworkMask mismatch warning message to include interface name and conflicting prefix lengths. 2006-07-07 Paul Jakma * ospf_nsm.h: Add a NSM_Deleted neighbour state, to act as dummy state indicating the neighbour is to be deleted. * ospf_nsm.c: (general) Use the NSM_Deleted state to delete neighbours, thus allowing code to be slightly more obvious in its flow. (nsm_timer_set) Add NSM_Deleted. Add another timer the code missed. (nsm_kill_nbr) No need for special case call to nsm_change_state anymore. Make the assert and error-handling for same case more readable (Andrew Schorr) Remove the call to ospf_nbr_delete, nsm_change_state can do this generally now via NSM_Deleted. (struct ... NSM) Add the dummy NSM_Deleted state, the 3 events that can lead to nsm_kill_nbr all now transition the NBR to NSM_Deleted and the general change_state function can be left to do the work. (ospf_nsm_event) Special casing of events and early-return can be removed now. On transition into Deleted, delete the nbr. * ospf_dump.c: (ospf_nsm_state_msg) Add Deleted. 2006-07-06 Paul Jakma * ospf_nsm.c: (ospf_nsm_event) LLDown event also results in nbr being deleted, requires early-return too. Likely explains some crash reports after interface events. 2006-07-04 Paul Jakma * ospf_nsm.c: (general) Various small cleanups from Andrew's review of last set of patches. (nsm_timer_set) Loading, Full and default can share same code too. (nsm_should_adj) Can just be one big OR. (nsm_twoway_received) Collapse into return statement. 2006-07-02 Paul Jakma * ospf_nsm.c: (nsm_should_adj) New function, just consolidate the 10.4 adjacency check from nsm_twoway_received/nsm_adj_ok. (nsm_twoway_received/nsm_adj_ok) Use former. (nsm_clear_adj) clear adjacency related state for a neighbour, needed for some state changes from > ExStart down to ExStart or less, which need not go through nsm_reset_nbr. (nsm_reset_nbr) move code to former. Should be static. (ospf_nsm_event) Don't allow action functions to change next_state if the NSM tables do not indicate next_state is conditional, log warning if one tries - existing code appears fine though. Remove long dead code. Use nsm_clear_adj for state changes that take down adjacencies to TwoWay/ExStart. (nsm_timer_set) ls_req timer should be OFF in early states. Compact several identical sections. Set inactivity timer to OFF for Down, for documentary purposes. (nsm_kill_nbr) Oops, action function shouldn't try return 1 for error. * ospf_lsa.c: (ospf_translated_nssa_refresh) CID #13. 2006-06-30 Andrew J. Schorr * 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 Andrew J. Schorr * ospf_nsm.c: (nsm_twoway_received) When deciding whether to change from state Init to ExStart, the test for whether the neighboring router is DR or BDR should be against the local router's notion of DR/BDR, not the neighbor's view. 2006-06-28 Erik Muller * 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. 2006-06-26 Paul Jakma * ospf_abr.c: (general) NSSA translate-candidate ABRs need to be ASBRs, or other routers may rightfully refuse to install translated type-5s LSAs. reported by dendroot@gmail.com. (ospf_abr_nssa_check_status) Detect change in translator state when ABR, and inc/dec redistribute count as when we leave/enter the disabled state - so that translate-enabled ABR properly sets ASBR bit on non-NSSA areas. Run the resulting function through indent to clean it up. * ospf_lsa.c: (router_lsa_flags) For purposes of ASBR bit, NSSA area is same as stub area. 2006-06-24 Andrew J. Schorr * ospf_snmp.c: (ospfTrapNbrStateChange, ospfTrapIfStateChange) Improve info log message to indicate why the trap is being sent. 2006-06-24 Andrew J. Schorr * ospf_dump.c: (config_write_debug) Fix typo to show debug ospf nsm status properly (not ism status). 2006-06-17 Andrew J. Schorr * 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 Paul Jakma * 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. 2006-05-31 Paul Jakma * ospf_lsdb.c: (ospf_lsdb_delete) robustify against NULL arguments, print warning. * ospf_lsa.c: (ospf_discard_from_db) ditto. (ospf_maxage_lsa_remover) Check lsa->lsdb for validity, possible mitigation (but not solution) for bug #269. 2006-05-30 Paul Jakma * ospf_packet.c: (ospf_read) Debug message about packets received on unenabled interfaces should be conditional on debug being set. 2006-05-23 Paul Jakma * ospf_vty.c: (general) Replace in-place route redistribution command and help strings with the new auto-generated defines from lib/route_types.h 2006-05-13 Paul Jakma * ospf_lsa.c: (ospf_translated_nssa_refresh) fix the sanity check to match the assert, small error in CID #13 fix. 2006-05-12 Paul Jakma * ospf_lsa.c: (ospf_lsa_action) Get rid of the ospf_lookup call, which is not checked for NULL return, by stripping out functionality which is never used, hence fixing Coverity CID #29. (struct lsa_action) remove unused member. (ospf_translated_nssa_refresh) Add non-assert sanity check, in case DEBUG isn't defined. Debug message when no type7 exists should print the ID from the type5, not the type7, fixes CID #13. * ospf_interface.c: (ospf_if_exists) Fix missing NULL return check on ospf_lookup, CID #27. * ospf_asbr.c: (ospf_redistribute_withdraw) remove ospf_lookup call by taking the struct ospf * as argument, which the caller has, fixing CID #28. * ospf_asbr.h: (ospf_redistribute_withdraw) update declaration * ospf_zebra.c: (ospf_redistribute_unset) update call to ospf_redistribute_withdraw to match. * ospf_ia.c: (ospf_update_router_route) ospf->backbone could be NULL when passed to ospf_find_asbr_route_through_area, check for NULL first, CID #14. * ospf_ism.c: (ism_change_state) NULL check on oi->area is useless, it's always valid. Only possibility where it couldn't be is if there is a race between abr_task and cleaning up oi's, in which case a NULL check here isn't going to do anything. Fixes CID #15. 2006-05-11 Paul Jakma * 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. (no_ospf_area_filter_list) Check NULL result from ospf_area_lookup_by_area_id, fixes Coverity CID #69 * ospf_route.c: (ospf_route_delete_same_ext) Fix deref before NULL check by moving into check-protected block, fix CID #49. * ospf_abr.c: (ospf_area_range_cost_set) Shouldn't create a new range, should just lookup to see if one exists, the new range is just leaked. Fixes CID #46. * ospf_lsa.c: (ospf_default_originate_timer) Let the thread take (struct ospf *) as thread argument, rather than (struct ospf *)->default_originate, thus avoiding having to call ospf_lookup. * ospf_zebra.c: (ospf_redistribute_default_set) change setup of ospf_default_originate_timer thread to match. * ospfd.c: (ospf_router_id_update) ditto. 2006-04-24 Paul Jakma * (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. 2006-04-03 Paul Jakma * (general) Fix issues with handling of Vlinks and entries in the nbrs route-table which were highlighted by the nsm/nbr_self fixes from bug #234. Many thanks to Juergen Kammer for his help and efforts in testing out debug patches to pinpoint the issue. * ospf_interface.c: (ospf_vl_new) Add nbr_self for Vlink. * ospf_neighbor.c: (ospf_nbr_key) new static function, helper to create key in nbrs table for a given nbr. (ospf_nbr_delete) Use ospf_nbr_key. Add an assert() to document an expected state. (ospf_nbr_add_self) Ditto. (ospf_nbr_lookup_by_addr) Add an assert. * ospf_nsm.c: (nsm_kill_nbr) Can never kill the nbr_self psuedo-neighbour. 2006-03-27 Paul Jakma * ospf_lsa.c: (ospf_lsa_checksum) Add an explicit cast to avoid the ambiguities of ANSI and C99 C with respect to type conversion. Detailed problem report and test case with example data supplied by Dmitry Ivanov . 2006-03-25 Paul Jakma * ospf_interface.c: (ospf_if_lookup_recv_if) Ignore loopbacks, we can never ever receive packets on those. Should fix case where CARP is run with address in same subnet as real interface. Problem report and diagnosis thanks to: Landon Fuller . However, ospf_read() still can't deal deterministically with multiple interfaces in same subnet. 2006-03-23 Steve Lawson * ospf_lsa.c: (ospf_lsa_install) Fix incorrect byte-order conversion of OSPF_MAX_SEQUENCE_NUMBER 2006-01-19 Paul Jakma * (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. 2006-01-18 Juergen Kammer * ospf_lsa.c: (ospf_router_lsa_new) dont take reference to the stream data until it is constructed, data reference is volatile due to the potential resize in link_info_set 2006-01-18 Paul Jakma * ospf_lsa.c: (link_info_set) Resize the stream if required and possible. Return number of links added. (lsa_link_*_set) use return value from previous. * ospf_lsa.h: Add OSPF_ROUTER_LSA_LINK_SIZE define. 2006-01-17 Paul Jakma * ospf_packet.c: (ospf_verify_header) print out the types involved if there's a mismatch. * ospf_zebra.c: (ospf_zebra_add) Adjust to new zserv format. 2006-01-10 Len Sorensen * (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. 2006-01-10 Juris Kalnins * ospf_zebra.c: (ospf_interface_address_delete) fix rare leak of struct connected in an error case. * ospf_packet.c: (ospf_make_md5_digest) fix odd, if not undefined effect, assignment of an increment expression. 2006-01-10 Paul Jakma * ospfd.c: (ospf_network_run) checking to see if router-id is set should be on ospf->router_id, not router_id_static. This was causing ospfd to not start if router-id had not been configured statically. (ospf_if_update) ditto. * ospf_vty.c: (config_write_ospf_distribute) trim down redundant strings. 2005-11-26 Paul Jakma * ospf_api.c: (struct opaque_lsa) change from gcc zero-length array to C99 incomplete type array. * (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) 2005-11-20 Paul Jakma * 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. * ospf_abr.c: (ospf_abr_announce_network_to_area) check returned LSA of ospf_summary_lsa_refresh and print warning if it failed. (ospf_abr_announce_network_to_area) similar (ospf_abr_announce_rtr_to_area) similar * ospf_lsa.c: (ospf_router_lsa_new) check LSA returned is valid. (ospf_router_lsa_originate) similar (ospf_router_lsa_refresh, ospf_network_lsa_new) similar (ospf_summary_lsa_new) Check ID is valid. (ospf_summary_lsa_originate) ditto, and check returned LSA from previous function is !NULL. (ospf_summary_lsa_refresh) check ospf_summary_lsa_new return is !NULL. (ospf_summary_asbr_lsa_new) ID valid check. (ospf_summary_asbr_lsa_originate) similar. 2005-11-16 Andrew J. Schorr * 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. 2005-11-16 Andrew J. Schorr * ospf_ism.h: (OSPF_ISM_TIMER_OFF) Improve macro syntax by enclosing in 'do {...} while(0)'. 2005-11-14 Paul Jakma * ospfd.c: (ospf_new) stub-shutdown should just default to unconfigured, too strange otherwise. (ospf_finish_final) t_opaque_lsa_self TIMER_OFF should be preprocessor conditional on HAVE_OPAQUE_LSA. * ospfd.h: (struct ospf) remove the SHUTDOWN_DEFAULT define. no longer used, plus it wasn't in range that the command accepted. * ospf_zebra.h: Depends on vty.h, include it. 2005-11-11 Paul Jakma * ospf_spf.c: (ospf_canonical_nexthops_free) Free only the nexthops pointing to the root vertex. We may visit a vertex twice or the vertex may have some inherited nexthops, if we free other nexthops we could crash. 2005-11-04 Paul Jakma * ospf_{dump,spf,vty}.c: Oops, use the internal tv_sub function rather than unportable timersub. 2005-11-03 Paul Jakma * ospf_apiserver.c: (apiserver_sync_callback) stray semi-colon * ospf_packet.c: include checksum.h, remove the in_cksum extern * prototypes. * ospf_te.h: Add braces, quell warning. * ospf_packet.c: Change level of some warnings to informational. 2005-10-29 Paul Jakma * (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. 2005-10-23 Paul Jakma * ospf_apiserver.c: (ospf_apiserver_term) This function should not have side-effects (eg segv) if no apiserver instances are active, ie be robust. * ospf_vty.c: (show_ip_ospf) fix display of SPF timer if it has not yet been run. 2005-10-21 Paul Jakma * 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. 2005-10-21 Paul Jakma * (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. 2005-10-21 Paul Jakma * (general) OSPF fast, sub-second hello and 1s dead-interval support. * 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. 2005-10-18 Paul Jakma * (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 2005-10-11 Paul Jakma * 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. 2005-10-06 Alain Ritoux * ospf_snmp.c: Avoid mixing interface and ospf_interface objects which now allows snmpwalk to work with ospfIfTable and also with ospfIfMetricTable 2005-10-01 Andrew J. Schorr * 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). 2005-09-30 Vincent Jardin * ospf_dump.c, ospf_ia.c, ospf_spf.c, ospf_ase.c: remove unused DEBUG 2005-09-29 Alain Ritoux * ospf_ism.c: generate SNMP traps on Interface state change * ospf_nsm.c: generate SNMP traps on Neighbour state change * ospf_snmp.[ch]: support for SNMP traps for interface and neighbours. 2005-09-29 Alain Ritoux * 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.h: define OSPF_MTU_IGNORE_DEFAULT * ospf_packet.c: support ignore-mtu option * ospf_interface.h: field added for skipping MTU check * ospf_interface.c: fix memory leak in ospf_crypt_key_delete() Set mtu_ignore field to default value * ospf_abr.[ch]: export ospf_abr_announce_network_to_area() * ospf_ism.h: add MACRO to convert internal ISM status into SNMP correct values * ospf_snmp.c: add sanity check on LSA type in lsdb_lookup_next() convert OSPFIFSTATE internal status into SNMP values 2005-09-28 Alain Ritoux * ospf_packet.c: use new md5 API 2005-09-19 Andrew J. Schorr * ospf_lsa.h: (ospf_external_lsa_flush) Comment out the 5th argument (nexthop) since it is not used in the function (except inside some commented-out code). * ospf_lsa.c: (ospf_external_lsa_flush,ospf_external_lsa_refresh) Comment out the 5th argument to ospf_external_lsa_flush. * ospf_asbr.c: (ospf_redistribute_withdraw) Comment out 5th arg to ospf_external_lsa_flush. * ospf_vty.c: (no_ospf_default_information_originate) Eliminate 5th uninitialized nexthop arg to ospf_external_lsa_flush. * ospf_zebra.c: (ospf_zebra_read_ipv4) Comment out 5th arg to ospf_external_lsa_flush. * ospfd.c: (ospf_network_set) Comment out 5th arg to ospf_external_lsa_flush. 2005-09-17 Andrew J. Schorr * ospf_opaque.c: (ospf_opaque_lsa_refresh_schedule,ospf_opaque_lsa_flush_schedule) No need to call ospf_lookup(), just use lsa0->area->ospf instead. 2005-08-21 Hasso Tepper * ospf_vty.c: Make "show ip ospf neighbor xxx" commands work. Interface should be specified by name now. 2005-08-17 Hasso Tepper * ospf_vty.c: Check carefully if interface exists before trying to print info about it. 2005-08-05 Hasso Tepper * ospf_zebra.c: Don't assert/stop before type == ZEBRA_ROUTE_MAX if dealing with routemaps. There is ospf->route_map[ZEBRA_ROUTE_MAX] for default-information. 2005-07-26 Paul Jakma * 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. 2005-07-12 Paul Jakma * 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. 2005-06-20 Hasso Tepper * ospf_nsm.c: Make database exchange for NSSA database work. 2005-06-13 Paul Jakma * 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 Hasso Tepper * ospf_apiserver.c: Fix obvious error in notifying clients about ISM changes - oi->ifp->status doesn't give to us info about ISM, oi->state does. 2005-06-01 Akihiro Mizutani * ospf_ism.c (ospf_elect_bdr/ospf_elect_dr): Fix DR election bug. 2005-05-26 Paul Jakma * ospf_abr.c: (ospf_abr_update_aggregate) Fix comment, cost bug itself had been fixed long ago by Sowmini. 2005-05-19 Paul Jakma * 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. 2005-05-11 Paul Jakma * (general) Fix memory leaks in opaque AS-scope LSAs, reported and with much debugging done by by scott collins . * 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. 2005-05-07 Yar Tikhiy * ospf_network.c: Log ifindex on multicast membership leave/join events. 2005-05-06 Paul Jakma * (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. 2005-04-15 Zhipeng Gong * 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). 2005-04-11 Andrew J. Schorr * ospf_zebra.c (ospf_zebra_add): Call zclient_send_message instead of writen. 2005-04-02 Andrew J. Schorr * ospf_interface.h: (ospf_if_lookup_by_name) Remove declaration of a function that does not exist. 2005-04-02 Andrew J. Schorr * ospf_zebra.c: (zebra_interface_if_lookup) Must use if_lookup_by_name_len. 2005-04-02 Andrew J. Schorr * ospf_interface.c: (ospf_vl_new) Use strnlen to fix call to if_create. 2005-04-02 Andrew J. Schorr * 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. 2005-03-31 Andrew J. Schorr * ospf_dump.c: (show_debugging_ospf) Show if ospf event debugging is turned on. 2005-03-29 Andrew J. Schorr * 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. 2005-03-29 Andrew J. Schorr * 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. 2005-03-29 Andrew J. Schorr * 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 Hasso Tepper * ospf_snmp.c: Don't crash in snmp query if ospf instance doesn't exist at all. 2005-03-25 Hasso Tepper * ospfd.h: Include log.h, fixes compile with gcc-4.0. 2005-03-13 Andrew J. Schorr * 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. 2005-02-23 Andrew J. Schorr * 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 Vincenzo Eramo * ospf_lsa.h: New flag to the LSA structure for the SPF calculation. * 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 Hasso Tepper * ospf_ase.c: Don't show messages related to the ase calculations if we are not debugging. 2005-02-19 Hasso Tepper * ospf_api.h: char isn't always signed, but it has to be it here. 2005-02-19 Paul Jakma * ospf_packet.c: (ospf_stream_copy) remove (ospf_packet_dup) use stream_copy instead of ospf_stream_copy 2005-02-17 Andrew J. Schorr * ospf_packet.c: (ospf_recv_packet) If there is somehow a runt packet in the queue, it must be discarded. Improve warning messages. Fix scope to static. (ospf_read) Fix bug: should reset the read thread in all cases to make sure we continue to get incoming messages. 2005-02-15 Paul Jakma * ospf_packet.c: (ospf_recv_packet) Fix silly error wrt allocating ibuf. Thanks Andrew. 2005-02-14 Paul Jakma * ospf_packet.c: (ospf_recv_packet) use stream_recvmsg. 2005-02-11 Hasso Tepper * ospf_lsdb.c: Fix sum of checksums calculation. 2005-02-09 Andrew J. Schorr * ospf_packet.c: (ospf_write) If sendmsg fails, give more info in the error message. 2005-02-08 Andrew J. Schorr * 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 * 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 * ospf_packet.c: (various) Remove unneeded stream_set_putp abuse. 2005-02-02 Andrew J. Schorr * ospf_packet.c: (ospf_read) Fix bug: must check for state ISM_Down, not for event ISM_InterfaceDown. And improve the message by adding the interface flags. 2005-01-30 Andrew J. Schorr * ospf_network.c: (ospf_sock_init) Save errno before calling ospfd_privs.change. 2005-01-29 Andrew J. Schorr * ospf_packet.c: (ospf_packet_add) If oi->obuf is NULL, print an error message and return. (ospf_read) If the interface state is ISM_InterfaceDown, issue a warning message and ignore the packet. 2005-01-10 Greg Troxel * ospf_packet.h: Remove commented out definition of OSPF_MAX_PACKET; neither it or the uncommented one are used any more. * ospf_packet.c (ospf_make_ls_upd): Leave room for authentication when deciding if an update will fit. (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 * ospf_network.c: Improve all setsockopt error messages to give detailed information on the arguments. 2004-12-29 Andrew J. Schorr * 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 * 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 * 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. Show numbers and sums of checksums for each type of LSAs. * ospf_lsa.c: Calculate checksum before putting LSA into database. 2004-12-15 Andrew J. Schorr * ospf_interface.h: Declare new function ospf_default_iftype. * ospf_interface.c: (ospf_default_iftype) New function to centralize this logic in one place. * ospf_zebra.c: (ospf_interface_add) Use new function ospf_default_iftype. * ospf_vty.c: (no_ip_ospf_network,config_write_interface) Fix logic by using new function ospf_default_iftype. 2004-12-11 Andrew J. Schorr * ospf_packet.c: (ospf_db_desc) Should be static, not global. (ospf_hello,ospf_db_desc,ospf_ls_upd,ospf_ls_ack) Improve warning messages to include identifying information (e.g. router id). * ospf_nsm.c: (nsm_change_state) Improve info message to include router id and state names. 2004-12-09 Greg Troxel * ospf_apiserver.c (ospf_apiserver_term): Obtain struct ospf_apiserver * from listnode. Remove unused variables. Follows suggestion from Jay Fenlason. 2004-12-08 Andrew J. Schorr * *.c: Change level of debug messages to LOG_DEBUG. 2004-12-07 Andrew J.

(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 * ospf_main.c: Remove #include "debug.h" (was not being used, and lib/debug.h has now been deleted). 2004-11-25 Hasso Tepper * ospf_main.c: Make group to run as configurable. 2004-11-15 Greg Troxel * 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 * ospf_{apiserver,te}.c: ospf_lsa_free's should be ospf_lsa_unlock. 2004-11-12 Paul Jakma * ospf_ia.c: (process_summary_lsa) Only an ABR has any reason to ignore stub area summary default. Even so it seems a strange check, add a comment to that effect. 2004-11-04 Paul Jakma * ospfd.c: (ospf_network_match_iface) revert to previous network statement match behaviour. 2004-11-02 Paul Jakma * ospf_packet.c: (ospf_write_frags) remove iov arg, msg already points to it. 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 * 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 * 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.

New command line switch to enable it. 2004-10-11 Paul Jakma * ospf_dump.c: (ospf_ip_header_dump) Assume header is in host order remove ntohs that should have dissappeared. Take struct ip as argument, caller has to know there's an IP header at start of stream anyway. * ospf_dump.h: update declaration of ospf_ip_header_dump. * ospf_packet.c: (ospf_write) correct call to sockopt_iphdrincl_swab_htosys which was munging the header. (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 * *.[c|h]: Fix compiler warnings: make some strings const, signed -> unsigned, remove unused variables etc. 2004-10-07 Greg Troxel * ospf_apiserver.c (ospf_apiserver_unregister_opaque_type): Don't use of variable names 'node' and 'nextnode' to avoid possible conflict with list macros. Move variable declaration inside for loop after a statement to top of function. 2004-10-07 Paul Jakma * ospf_snmp.c: Missed list typedef update * ospf_dump.c: Include sockopt.h for header swab functions. 2004-10-05 Paul Jakma * ospf_packet.c: replace ospf_swap_iph_to... with sockopt_iphdrincl_swab_... 2004-10-03 James R. Leu * ospf_zebra.c: Read router id related messages from zebra daemon. Schedule router-id update thread if it's changed. * ospfd.c: Remove own router-id selection function. Use router id from zebra daemon if it isn't manually overriden in configuration. 2004-09-27 Paul Jakma * ospf_dump.c: (ospf_ip_header_dump) Use HAVE_IP_HDRINCL_BSD_ORDER Apply to offset too. Print ip_cksum, lets not worry about possible 2.0.37 compile problems. * ospf_packet.c: (ospf_swap_iph_to{n,h}) Use HAVE_IP_HDRINCL_BSD_ORDER. (ospf_recv_packet) ditto. (ospf_write) Fixup iov argument to ospf_write_frags. (struct msghdr).msg_name is caddr_t on most platforms. (ospf_recv_packet) ditto. And msg_flags is not always there memset struct then set fields we care about rather than initialise all fields individually. 2004-09-26 Hasso Tepper * ospf_abr.c, ospf_dump.c, ospf_lsa.c, ospf_packet.c, ospf_vty.c, ospf_zebra.c: Fix compiler warnings. 2004-09-24 Paul Jakma * ospf_apiserver.{c,h}: lists typedef removal cleanup. update some list loops to LIST_LOOP. some miscellaneous indent fixups. (ospf_apiserver_unregister_opaque_type) fix listnode_delete of referenced node in loop. (ospf_apiserver_term) loops calling ospf_apiserver_free, which deletes referenced nodes from apiserver_list, fixed. * ospf_interface.h: lists typedef removal cleanup. * ospf_opaque.{c,h}: lists typedef removal cleanup. update some list loops to LIST_LOOP. miscellaneous style and indent fixups. * ospf_te.{c,h}: ditto * ospf_packet.c: lists typedef removal cleanup.

(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 * ospf_spf.c (ospf_spf_calculate): Many more comments and debug print statements.

Fixes Bugzilla #108. 2004-08-27 David Wiggins * 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 * 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 * ospf_packet.c: update to match sockopt renames. 2004-08-04 Paul Jakma * ospf_spf.c: (ospf_spf_consider_nexthop) Add comment about issue. Compare only against list head - all nexthops must be same cost anyway, fixes a reference-listnode-after-delete bug noted by Kir Kostuchenko. (ospf_nexthop_calculation) Use ospf_spf_consider_nexthop for all candidates attached to root. 2004-07-27 Paul Jakma * ospf_packet.c: (ospf_ls_upd_send_queue_event) fix thinko from last fix for ospfd wedging due to oversize LSAs: dont list loop on ospf_ls_upd_queue_send() - guaranteed segfault. 2004-07-27 Paul Jakma * ospf_opaque.c: (ospf_opaque_lsa_flush_schedule) do not NULL out the LSA as then free_opaque_info_per_id() can never unlock (and free) the LSA. Reported by Gunnar Stigen. 2004-07-23 Paul Jakma * ospf_network.c: Replace PKTINFO/RECVIF with call to setsockopt_pktinfo * ospf_packet.c: Use getsockopt_pktinfo_ifindex and SOPT_SIZE_CMSG_PKTINFO_IPV4. 2004-07-14 Paul Jakma * ospf_packet.c: (ospf_ls_upd_send_queue_event) Partial fix for problem reported by Peter Frost amongst others, where function will spin indefinitely if update list contains LSAs greater than MTU-headers or other condition leading to update list never being cleared. Problem of what to do with these LSAs remains. (ospf_make_ls_upd) add comment about large LSA problem, indentation cleanup. 2004-07-01 Greg Troxel * Makefile.am (lib_LTLIBRARIES): make libospf shared 2004-06-30 Greg Troxel * Makefile.am: Add shlib support. 2004-06-10 Hasso Tepper * *: Removed ifdefs HAVE_NSSA. 2004-06-06 Paul Jakma * ospf_dump.c,ospf_lsa.c: Fix typos of merge of previous. ospf_flood.c: (ospf_process_self_originated_lsa) fix zlog format 2004-05-31 Sagun Shakya * ospf_dump.c: (ospf_lsa_header_dump) LOOKUP can return null if index is out of range. ospf_flood.c: endianness fix ospf_lsa.c: Missing ntohl's on (struct lsa *)->data->ls_seqnum in various places. 2004-05-10 Hasso Tepper * ospf_zebra.c, ospfd.c: Move ospf_prefix_list_update() function to ospf_zebra.c from ospfd.c and add redistribution updates if route-map is used in redistribution. * ospf_main.c: Remove now useless call to ospf_init(). 2004-05-08 Paul Jakma * ospf_zebra.c: Sync with lib/zclient changes 2004-05-05 Paul Jakma * ospf_network.c: (ospf_sock_init) Check whether IP_HDRINCL is defined.
