* It's possible for the packet output buffer to be filled up with a long
series of non-Hello packets in between Hellos packets, such that the
router's neighbours don't receive the Hello packet in time, even though
the hello-timer ran at about the right time. Fix this by prioritising
Hello packets, letting them skip the queue and go ahead of any packets
already on the queue.
This problem can occur when there are lots of LSAs and slow links.
* ospf_packet.h: (ospf_hello_send_sub) not used outside of ospf_packet.c
* ospf_packet.c: (ospf_fifo_push_head) add packet to head of fifo (so its
no longer really a fifo, but hey)
(ospf_packet_add_top) add packet to top of the packet output queue.
(ospf_hello_send_sub) Put Hello's at the top of the packet output queue.
make it take in_addr_t parameter, so that this
ospf_hello_send can re-use this code too.
(ospf_hello_send) consolidate code by using ospf_hello_send_sub
(ospf_poll_send,ospf_hello_reply_timer) adjust for ospf_hello_send_sub.

* The hello protocol monitors connectivity in 2 different ways:
a) local -> remote
b) remote -> local
Connectivity is required in both directions (2-way) for adjacencies to
form.
The first requires a round-trip to detect, and is done by advertising
which other hosts a router knows about in its hello messages. This allows
a host to detect which other routers are and are not receiving its
message. If a remote neighbour delists the local router, then the local
router raises a "1-Way Received" event.
The latter is straight-forward, and is detected by setting a timer for the
neighbour. If another Hello packet is not received within this time then
the neighbour is dead, and a separate "Inactive" event is raised.
These are 2 different and relatively independent measures.
Knowing that we can optimise the 2nd, remote->local measure and reset
the timer when /any/ packet arrives from that neighbour. For any packet
is as good as a Hello packet. This can help in marginal situations, where
the number of protocol messages that must be sent sometimes can exceed
the capacity of the network to transmit the messages within the configured
dead-time. I.e. an OSPF network with lots of LSAs, slow links and/or
slow hosts (e.g. O(10k) LSAs, O(100kbit) links, embedded CPUs, and O(10s)
dead-times).
This optimisation allows an OSPF network to run closer to this margin,
and/or allows networks to perhaps better cope with rare periods of
exceptional load, where otherwise they would not.
It's fully compatible with plain OSPF implementations and doesn't
prejudice dead-neighbour detection.
* ospf_nsm.h: Rename HelloReceived event to PacketReceived.
* ospf_nsm.c: (nsm_hello_received) -> nsm_packet_received
* ospf_packet.c: Schedule PacketReceived whenever a valid message is
received.
|
|
* ospf_packet.c: (ospf_ls_upd) the corresponding test on the arrival side
in (ospf_flood) is <, so this should be >=, not >, purely for consistency.
There is no practical effect here though.
|
|
* ospf_packet.c: (ospf_ls_upd) DISCARD_LSA continues, and so should be
after debug messages, not before them.
|
|
* ospf_packet.c: make this message conditional on 'debug ospf event', as it
be easily triggered with, e.g., multiple subnets sharing same physical
network. E.g, see bug #532.

This function will return the interface for the first matching
remote address for PtP i/f's. That won't work for multiple
unnumbered i/f's as these may all have the same address.
Pass in the struct interface pointer, ifp, to find the
correct set of oi's to search in. This also reduces the
size of the search list, making it faster.
* ospfd/ospf_interface.c: Add struct interface * param to
ospf_if_lookup_recv_if() to select the right list to search in.
* ospfd/ospf_interface.h: ditto.
* ospfd/ospf_packet.c: Pass new ifp argument to ospf_if_lookup_recv_if()
|
|
|
|
* ospf_packet.c: Apply passive check and drop for all packages
and not just Hellos.

Update ospf_db_desc_send(), ospf_ls_upd_queue_send() and ospf_ls_req_send()
to always use OSPF_ALLSPFROUTERS for PtP links.
See RFC 2328, chap 8.1 for details:
"The IP destination address for the packet is selected as
follows. On physical point-to-point networks, the IP
destination is always set to the address AllSPFRouters."
Without this, it won't be possible to establish adjacencies on
multiple unnumbered links to the same router.
ChangeLog:
2008-07-25 Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* ospfd/ospf_packet.c: Set destination for PtP links to
OSPF_ALLSPFROUTERS.

* configure.ac: sys/conf.h depends on sys/param.h, at least on
FBSD 6.2.
(bug #363) Should check for in_pktinfo for IRDP
2006-05-27 Paul Jakma <paul.jakma@sun.com>
* configure.ac: General cleanup of header and type checks, introducing
an internal define, QUAGGA_INCLUDES, to build up a list of
stuff to include so as to avoid 'present but cant be compiled'
warnings.
Misc additional checks of things missing according to autoscan.
Add LIBM, for bgpd's use of libm, so as to avoid burdening
LIBS, and all the binaries, with libm linkage.
Remove the bad practice of using m4 changequote(), just
quote the []'s in the case statements properly.
This should fix bugs 162, 303 and 178.
* */*.{c,h}: Update all HAVE_* to the standard autoconf namespaced
HAVE_* defines. I.e. HAVE_SA_LEN -> HAVE_STRUCT_SOCKADDR_SA_LEN,
* bgpd/Makefile.am: Add LIBM to bgpd's LDADD, for pow().

2006-10-22 Yar Tikhiy <yar@comp.chem.msu.su>
* (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.

Fix zlog_warn messages to eliminate compiler warnings.
(ospf_hello) Improve warning messages to show why we
are complaining.

2006-08-28 Andy Gay <andy@andynet.net>
* 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.
|

2006-08-25 Paul Jakma <paul.jakma@sun.com>
* (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.
|

2006-08-03 Paul Jakma <paul.jakma@sun.com>
* ospf_packet.c: (ospf_make_db_desc) Implement
draft-ogier-ospf-dbex-opt DB-exchange optimisation.
|
|
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.
(ospf_db_desc) use UNSET_FLAG macro.

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.
|
|
2006-07-10 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.
|

2006-06-15 Paul Jakma <paul.jakma@sun.com>
* Reported by Milan Koci
* ospf_interface.h: (struct ospf_if_info) Add reference counts
for multicast group memberships. Add various macros to help
manipulate/check membership state.
* ospf_interface.c: (ospf_if_set_multicast) Maintain the
ospf_if_info reference counts, and only actually drop
memberships if it hits 0, to avoid losing membership when
OSPF is disabled on an interface with multiple active OSPF
interfaces.
* ospf_packet.c: (ospf_{hello,read}) Use the new macros to
check/set
multicast membership.
* ospf_vty.c: (show_ip_ospf_interface_sub) ditto.
|
|
2006-05-30 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.

2006-01-17 Paul Jakma <paul.jakma@sun.com>
* ospf_packet.c: (ospf_verify_header) print out the types
involved if there's a mismatch.

2006-01-10 Juris Kalnins <juris@mt.lv>
* ospf_packet.c: (ospf_make_md5_digest) fix odd, if not
undefined effect, assignment of an increment expression.
|
|
* ospf_packet.c: Change level of some warnings to
informational.
|
|
* 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.
|
|
* (general) SPF millisecond resolution timer with adaptive,
linear back-off holdtime. Prettification of ospf_timer_dump.
* ospf_dump.c: (ospf_timeval_dump) new function. The guts of
ospf_timer_dump, but made to be more dynamic in printing out
the relative timeval, sliding the precision printed out
according to the value.
(ospf_timer_dump) guts moved to ospf_timeval_dump.
* ospf_dump.h: export ospf_timeval_dump.
* ospf_flood.c: (ospf_flood) remove gettimeofday, use
the libzebra exported recent_time instead, as it's not
terribly critical to have time exactly right - the dropped
LSA will be retransmited to us if we don't ACK it.
* ospf_packet.c: (ospf_ls_upd_timer) Ditto, but here we're
not transmitting, just putting LSA back on update transmit list.
* ospfd.h: delay and holdtimes should be unsigned.
Add spf_max_holdtime and spf_hold_multiplier.
Update default defines for delay and hold time to be in msec.
(struct ospf) change the SPF timestamp to a struct timeval.
Remove ospf_timers_spf_(un)?set.
* ospfd.c: (ospf_timers_spf_{set,unset}) removed.
(ospf_new) initialise spf_max_holdtime and spf_hold_multiplier
* ospf_spf.c: (ospf_spf_calculate) SPF timestamp is a timeval
now, update with gettimeofday.
(ospf_spf_calculate_schedule) Change SPF timers to millisecond
resolution.
Make the holdtime be adaptive, with a linear increase in
holdtime ever consecutive SPF run which occurs within holdtime
of previous SPF, bounded by spf_max_holdtime.
* ospf_vty.c: Update spf timers commands.
(ospf_timers_spf_set) trivial helper.
(ospf_timers_throttle_spf_cmd) new command to set SPF delay,
initial hold and max hold times with millisecond resolution.
(ospf_timers_spf_cmd) Deprecated. Accept the old values,
convert to msec, truncate to new limits.
(no_ospf_timers_throttle_spf_cmd) set timers to defaults.
(no_ospf_timers_spf_cmd) deprecated form, same as previous.
(show_ip_ospf_cmd) Display SPF parameters and times.
(show_ip_ospf_neighbour_header) Centralise the 'sh ip os ne'
header.
(show_ip_ospf_neighbor_sub) Fix the field widths. Get rid of
the multiple spaces which were making the lines even longer.
(show_ip_ospf_neighbor_cmd) Use show_ip_ospf_neighbour_header
(show_ip_ospf_neighbor_all_cmd) ditto and fix the field
widths for NBMA neighbours.
(show_ip_ospf_neighbor_int) Use header function.
(show_ip_ospf_nbr_nbma_detail_sub) use sizeof for timebuf,
local array - safer.
(show_ip_ospf_neighbor_detail_sub) ditto
(ospf_vty_init) install the new SPF throttle timer commands.

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

correct values
* ospfd/ospf_snmp.c: add sanity check on LSA type in lsdb_lookup_next()
convert OSPFIFSTATE internal status into SNMP values
|
|
* lib/md5-gnu.h: removed
* lib/md5.h: replaces md5-gnu.h
* lib/Makefile.am: use correct md5.h
* lib/md5.c: import from WIDE
* ospfd/ospf_packet.c: use new md5 API
* ripd/ripd.c: use new md5 API
|
|
* (general) Fix memory leaks in opaque AS-scope LSAs, reported and
with much debugging done by by scott collins <scollins@agile.tv>.
(possible backport candidate?)
* ospf_lsa.c: (ospf_discard_from_db) dont call
ospf_ase_unregister_external_lsa for opaque-lsa's, opaques are
never registered with ase in the first place.
* ospf_packet.c: (general) Disabuse opaque related code of its
tendency to try gather up things into temporary lists.
(ospf_ls_upd) remove the temporary lists opaque uses, call
opaque functions inline, just like all other types.
(ospf_ls_ack) ditto.
(ospf_recv_packet) fixup sign warning.
* ospf_opaque.c: (general) fix the unneeded use of lists, and
untwist some of the logic.
(ospf_opaque_self_originated_lsa_received) take a single LSA
as argument, not a list of them. Remove the list loop. Logic
otherwise unchanged.
(ospf_opaque_ls_ack_received) Mostly ditto. But untwist the logic,
move the actions up into the switch block, remove the goto's and
sanitise the logic near the end a bit.
* ospf_opaque.h: Adjust definitions of aforementioned functions
in ospf_opaque.c to match.
|
|
* (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.
|
|
* (global): Fix up list loops to match changes in lib/linklist,
and some basic auditing of usage.
* configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES
* HACKING: Add notes about deprecating interfaces and commands.
* lib/linklist.h: Add usage comments.
Rename getdata macro to listgetdata.
Rename nextnode to listnextnode and fix its odd behaviour to be
less dangerous.
Make listgetdata macro assert node is not null, NULL list entries
should be bug condition.
ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use
with for loop, Suggested by Jim Carlson of Sun.
Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the
"safety" of previous macro.
LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to
distinguish from the similarly named functions, and reflect their
effect better.
Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section
with the old defines which were modified above,
for backwards compatibility - guarded to prevent Quagga using it..
* lib/linklist.c: fix up for linklist.h changes.
* ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single
scan of the area list, rather than scanning all areas first for
INTER_ROUTER and then again for INTER_NETWORK. According to
16.2, the scan should be area specific anyway, and further
ospf6d does not seem to implement 16.3 anyway.
|
|
* 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.
|
|
* 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.
|
|
* ospf_packet.c: (ospf_stream_copy) remove
(ospf_packet_dup) use stream_copy instead of ospf_stream_copy
|
|
* 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.
|
|
* ospf_packet.c: (ospf_recv_packet) Fix silly error wrt allocating
ibuf. Thanks Andrew.
|
|
* ospf_packet.c: (ospf_recv_packet) use stream_recvmsg.
2005-02-11 Hasso Tepper <hasso at quagga.net>
* ospf_lsdb.c: Fix sum of checksums calculation.
2005-02-09 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_packet.c: (ospf_write) If sendmsg fails, give more info in the
error message.
2005-02-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_interface.h: Reduce structure padding by putting new u_char
field multicast_memberships in a better spot (grouped with
other u_char fields type and state).
2005-02-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_interface.h: Improve passive_interface comment. Add new
multicast_memberships bitmask to struct ospf_interface to track
active multicast subscriptions. Declare new function
ospf_if_set_multicast.
* ospf_interface.c: (ospf_if_set_multicast) New function to configure
multicast memberships properly based on the current
multicast_memberships status and the current values of the
ospf_interface state, type, and passive_interface status.
(ospf_if_up) Remove call to ospf_if_add_allspfrouters (this is
now handled by ism_change_state's call to ospf_if_set_multicast).
(ospf_if_down) Remove call to ospf_if_drop_allspfrouters (now
handled by ism_change_state).
* ospf_ism.c: (ospf_dr_election) Remove logic to join or leave
the DRouters multicast group (now handled by ism_change_state's call
to ospf_if_set_multicast).
(ism_change_state) Add call to ospf_if_set_multicast to change
multicast memberships as necessary to reflect the new interface state.
* ospf_packet.c: (ospf_hello) When a Hello packet is received on a
passive interface: 1. Increase the severity of the error message
from LOG_INFO to LOG_WARNING; 2. Add more information to the error
message (packet destination address and interface address);
and 3. If the packet was sent to ospf-all-routers, then try
to fix the multicast group memberships.
(ospf_read) When a packet is received on an interface whose state
is ISM_Down, enhance the warning message to show the packet
destination address, and try to update/fix the multicast group
memberships if the packet was sent to a multicast address.
When a packet is received for ospf-designated-routers, but the
current interface state is not DR or BDR, then increase the
severity level of the error message from LOG_INFO to LOG_WARNING,
and try to fix the multicast group memberships.
* ospf_vty.c: (ospf_passive_interface) Call ospf_if_set_multicast for
any ospf interface that may have changed from active to passive.

2004-11-12 Paul Jakma <paul@dishone.st>
* ospf_ia.c: (process_summary_lsa) Only an ABR has any reason to

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

candidates attached to root.
2004-07-27 Paul Jakma <paul@dishone.st>

* ospf_network.c: Replace PKTINFO/RECVIF with call to
setsockopt_pktinfo

multicast memberships properly based on the current
multicast_memberships status and the current values of the
ospf_interface state, type, and passive_interface status.

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.

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.

messages from LOG_WARNING to LOG_INFO, since this seems to be
normal.
|
|
* 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.
|
|
|
|
* ospf_packet.c: (ospf_db_desc) Should be static, not global.
(ospf_hello,ospf_db_desc,ospf_ls_upd,ospf_ls_ack) Improve warning
