blob: 05f96ace29f01ccd8c475231f55baba3636908b5 [file] [log] [blame]
2006-08-04 Paul Jakma <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* 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 <ajschorr@alumni.princeton.edu>
* 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 <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* 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 <ajschorr@alumni.princeton.edu>
* ospf_packet.c: (ospf_hello) Improve NetworkMask mismatch warning
message to include interface name and conflicting prefix lengths.
2006-07-07 Paul Jakma <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* 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 <ajschorr@alumni.princeton.edu>
* ospf_vty.c: (show_ip_ospf_neighbor_id) Should show all instances
of that neighbor (since it may appear on multiple interfaces)
instead of bailing out after showing the first match.
2006-06-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* 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 <erikm@internap.com>
* ospfd.h: Define 2 new struct ospf config flags:
OSPF_LOG_ADJACENCY_CHANGES and OSPF_LOG_ADJACENCY_DETAIL
* ospf_nsm.c (nsm_change_state): Log adjacency changes if
requested.
* ospf_vty.c (ospf_log_adjacency_changes): New command function
to implement ospf subcommand "log-adjacency-changes [detail]".
(no_ospf_log_adjacency_changes) Turn off log-adjacency-changes.
(show_ip_ospf) Show whether adjacency changes are logged.
(ospf_config_write) Add "log-adjacency-changes [detail]" to config.
(ospf_vty_init) Add ospf_log_adjacency_changes and

2006-06-26 Paul Jakma <paul.jakma@sun.com>
* 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 <ajschorr@alumni.princeton.edu>
* ospf_snmp.c: (ospfTrapNbrStateChange, ospfTrapIfStateChange) Improve
info log message to indicate why the trap is being sent.
2006-06-24 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_dump.c: (config_write_debug) Fix typo to show debug ospf nsm
status properly (not ism status).
2006-06-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_vty.c: ({no_,}ospf_passive_interface) Replace if_lookup_by_name
with a call to if_get_by_name -- if the interface does not exist
already, it should be created. And remove the obsolete warning
message.
2006-06-15 Paul Jakma <paul.jakma@sun.com>
* 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.

mitigation (but not solution) for bug #269.
2006-05-30 Paul Jakma <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>

check to match the assert, small error in CID #13 fix.
2006-05-12 Paul Jakma <paul.jakma@sun.com>
* 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.

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 <paul.jakma@sun.com>
* ospf_vty.c: (general) Audit ospf_lookup calls in commands,
ensure check for NULL result, make vty messages consistent.

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.

of ospf_default_originate_timer thread to match.
* ospfd.c: (ospf_router_id_update) ditto.

* 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.

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.

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.

2006-03-25 Paul Jakma <paul.jakma@sun.com>
* 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 <landonf@opendarwin.org>.
However, ospf_read() still can't deal deterministically with
multiple interfaces in same subnet.
2006-03-23 Steve Lawson <steve.lawson@aheadcomusa.com>

been configured statically.
(ospf_if_update) ditto.
* ospf_vty.c: (config_write_ospf_distribute) trim down
redundant strings.
2005-11-26 Paul Jakma <paul.jakma@sun.com>

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.

remove call to exit, as ospf_terminate now deals with
exiting.

* 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_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.

2005-10-23 Paul Jakma <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* (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 <paul.jakma@sun.com>
* (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 <paul.jakma@sun.com>
* (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 <paul.jakma@sun.com>
* 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 <alain.ritoux@6wind.com>
* 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 <ajschorr@alumni.princeton.edu>
* 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 <vincent.jardin@6wind.com>
* ospf_dump.c, ospf_ia.c, ospf_spf.c, ospf_ase.c:

uninitialized nexthop arg to ospf_external_lsa_flush.
* ospf_zebra.c: (ospf_zebra_read_ipv4) Comment out 5th arg
to ospf_external_lsa_flush.

to ospf_external_lsa_flush.
2005-09-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* 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 <hasso at quagga.net>
* ospf_vty.c: Make "show ip ospf neighbor xxx" commands work.
Interface should be specified by name now.
2005-08-17 Hasso Tepper <hasso at quagga.net>
* ospf_vty.c: Check carefully if interface exists before trying to
print info about it.
2005-08-05 Hasso Tepper <hasso at quagga.net>
* 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 <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* 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 <hasso at quagga.net>
* ospf_nsm.c: Make database exchange for NSSA database work.
2005-06-13 Paul Jakma <paul.jakma@sun.com>
* 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 <hasso at quagga.net>
* 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 <mizutani@net-chef.net>
* ospf_ism.c (ospf_elect_bdr/ospf_elect_dr): Fix DR election bug.
2005-05-26 Paul Jakma <paul.jakma@sun.com>
* ospf_abr.c: (ospf_abr_update_aggregate) Fix comment, cost bug itself
had been fixed long ago by Sowmini.
2005-05-19 Paul Jakma <paul.jakma@sun.com>
* 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 <paul.jakma@sun.com>
* (general) Fix memory leaks in opaque AS-scope LSAs, reported and
with much debugging done by by scott collins <scollins@agile.tv>.
* 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 <yar@comp.chem.msu.su>
* ospf_network.c: Log ifindex on multicast membership leave/join
events.
2005-05-06 Paul Jakma <paul.jakma@sun.com>

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 <zpgong@cdc.3upsystems.com>
* 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 <ajschorr@alumni.princeton.edu>
* ospf_zebra.c (ospf_zebra_add): Call zclient_send_message instead
of writen.
2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

function that does not exist.
2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_zebra.c: (zebra_interface_if_lookup) Must use
if_lookup_by_name_len.
2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_interface.c: (ospf_vl_new) Use strnlen to fix call to if_create.
2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* 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 <ajschorr@alumni.princeton.edu>
* ospf_dump.c: (show_debugging_ospf) Show if ospf event debugging
is turned on.
2005-03-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* 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 <ajschorr@alumni.princeton.edu>
* 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 <ajschorr@alumni.princeton.edu>
* 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 <hasso at quagga.net>
* ospf_snmp.c: Don't crash in snmp query if ospf instance doesn't
exist at all.
2005-03-25 Hasso Tepper <hasso at quagga.net>
* ospfd.h: Include log.h, fixes compile with gcc-4.0.
2005-03-13 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* 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 <ajschorr@alumni.princeton.edu>
* 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 <eramo at infocom.ing.uniroma1.it>
* 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 <hasso at quagga.net>
* ospf_ase.c: Don't show messages related to the ase calculations if

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. Even so it seems a strange
check, add a comment to that effect.

statement match behaviour.
2004-11-02 Paul Jakma <paul@dishone.st>

fixing the unfortunate borkenness introduced in moving of this code
to a function.
(ospf_write) remove iovp and fix up call to previous.

(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

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

* ospf_packet.c: (ospf_write) correct call to
sockopt_iphdrincl_swab_htosys which was munging the header.

we have it.
* (global) Const char update and signed/unsigned fixes.

HAVE_IP_HDRINCL_BSD_ORDER.
(ospf_recv_packet) ditto.

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.

in on-stack struct prefix_ipv4. Fixes point-to-multipoint SPF
calculation.

* ospf_packet.c (ospf_recv_packet): adjust size declaration of
buffer used to get interface index so that it compiles on other

this was only working on sparc/sparc64 because most of
sockaddr_dl was not being written.

* ospf_packet.c: update to match sockopt renames.
2004-08-04 Paul Jakma <paul@dishone.st>
