The previous formula for calculating delay was:
delay = OSPF_LS_REFRESH_TIME - LS_AGE (lsa) - OSPF_LS_REFRESH_JITTER
+ (random () % (2*OSPF_LS_REFRESH_JITTER));
If LS_AGE() is 0 we get:
delay = 1800 - 0 - 60 + (random() % 2*60)
So delay will be 1740 + 0..120, so we could easily pick a delay that is
greater than OSPF_LS_REFRESH_TIME (1800). For the normal case where
we hit this else the LS_AGE will be > 0 so that reduces the chances of
delay being greater than 1800.

CM-6802 – Currently, BFD session status can be monitored only through ptmctl. There is no way to check the BFD status of a peer/neighbor through Quagga. Debugging becomes easier if BFD status is shown in Quagga too. BFD status is relevant when it is shown against the BGP peer/OSPF neighbor. For, this following code changes have been done:
- Only down messages from PTM were being propagated from Zebra daemon to clients (bgpd, ospfd and ospf6d). Now, both up and down messages are redistributed to the clients from zebra. BFD status field has been added to the messaging. Handling of BFD session up messages has been added to the client code. BGP/OSPF neighbor is brought down only if the old BFD session status is ‘Up’ to handle extra/initial down messages.
- BFD status and last update timestamp fields have been added to the common BFD info structure. Also, common show functions for showing BFD information have been added to BFD lib.
- Modified the BGP neighbor show functions to call common BFD lib functions.
- For ospf and ospf6, BFD information was maintained only at interface level. To show BFD status per neighbor, BFD information has been added at neighbor level too. “show ip ospf interface”, “show ip ospf neighbor detail”, “show ipv6 ospf6 interface” and “show ipv6 ospf6 neighbor detail” output have been modified to show BFD information.
CM-6952 - IBGP peers were always assumed to be multi-hop since there was no easy way to determine whether an IBGP peer was single hop or multihop unlike EBGP. But, this is causing problem with IBGP link local peers since BFD doesn't allow multihop BFD session with link local IP addresses. Link local peers were discovered when the interface peering was enabled. Interface peering is always singlehop. So, added checks to treat all interface based peers as single hop irrespective of whether the peer is IBGP or EBGP.

At the minimum, the OSPF_LSA_SELF logic isnt foolproof, and it may hit assert
in ospf_refresh_unregister_lsa on a router-id change.
Once OSPF has created and flooded LSAs, its not a good idea to change
router-id inline. Tying it to restart has at least two benefits:
- Implementation can remain sane by not having to re-adjust neighbors and LSAs,
based on the new router-id.
- Works as a deterrent for the user to not meddle with the router-id unless
really needed.
is executed, then the init.d/quagga script doesnt wait more than 120 seconds
for the daemon do stop, worse, it goes ahead and starts the new daemon
regardless. This can result into two ospfd processes running on the same config.
Which leads to many issues including but not limited to high cpu usage.
Thats because the two processes are mixing packets on adjancencies thus
causing churn on the box and network.
As long as OSPF is able to reliably send the max-metric router-lsa before
exiting thats mostly good enough for this purpose anyways.
As a solution to this situation, bringing the maximum configurable value of
the on-shutdown timer below the maximum retry to stop a daemon in init.d/quagga
Notes: This may not be an upstreamable patch, still we needed to find
a solution for init.d/quagga and this command this co-exist.
——————————————-------------
- etc/init.d/quagga is modified to support creating separate ospf daemon
process for each instance. Each individual instance is monitored by
watchquagga just like any protocol daemons.(requires initd-mi.patch).
- Vtysh is modified to able to connect to multiple daemons of the same
protocol (supported for OSPF only for now).
- ospfd is modified to remember the Instance-ID that its invoked with. For
the entire life of the process it caters to any command request that
matches that instance-ID (unless its a non instance specific command).
Routes/messages to zebra are tagged with instance-ID.
- zebra route/redistribute mechanisms are modified to work with
[protocol type + instance-id]
- bgpd now has ability to have multiple instance specific redistribution
for a protocol (OSPF only supported/tested for now).
- zlog ability to display instance-id besides the protocol/daemon name.
- Changes in other daemons are to because of the needed integration with

separate instance specific APIs.)
- config/show/debug commands are modified to take instance-id argument

show commands etc.
To enable multiple instances, do the following:
1. service quagga stop
2. Modify /etc/quagga/daemons to add instance-ids of each desired
instance in the following format:
ospfd=“yes"
ospfd_instances="1,2,3"
assuming you want to enable 3 instances with those instance ids.
3. Create corresponding ospfd config files as ospfd-1.conf, ospfd-2.conf
and ospfd-3.conf.
4. service quagga start/restart
5. Verify that the deamons are started as expected. You should see
ospfd started with -n <instance-id> option.
ps –ef | grep quagga
With that /var/run/quagga/ should have ospfd-<instance-id>.pid and
ospfd-<instance-id>/vty to each instance.
6. vtysh to work with instances as you would with any other deamons.
7. Overall most quagga semantics are the same working with the instance
deamon, like it is for any other daemon.
NOTE:
To safeguard against errors leading to too many processes getting invoked,
a hard limit on number of instance-ids is in place, currently its 5.
Allowed instance-id range is <1-65535>
Once daemons are up, show running from vtysh should show the instance-id
of each daemon as 'router ospf <instance-id>’ (without needing explicit
configuration)
Instance-id can not be changed via vtysh, other router ospf configuration
is allowed as before.

OSPFd only allocates some stub information for loopback interfaces.
This causes a crash when the interface state machine is started on
that interface by configuring a different network type.
It doesn't make much sense to configure the network type of a loopback
interface, therefore, just forbid it.

Store the MaxAge LSA list in a tree instead of a linked list for efficient access.
Walking the list can be quite inefficient in some large systems and under certain tests.
ospfd maintains the list of LSA's that have been MaxAge'd out in a separate
linked list for removal by a remover/walker thread. When a new LSA is to be
installed, the old LSA is ejected and when it is ejected, the MaxAge LSA list
is traversed to ensure that the old LSA is also removed from this list if it
exists on this list.
When a large number (> 5K) MaxAge LSAs are bombarding the system, walking this
list takes a significant time causing timers to fire and actions to be taken
such as expiring neighbors due to expiry of DeadInterval (especially when timer
is really low, <= 12s), creating a spiral of instability.
By making this MaxAge LSA list be a tree, this problem is mitigated.

* (general) Get rid of the router and network LSA specific refresh timers
and make the general refresher do this instead. Get rid of the twiddling
of timers for router/network LSA that was spread across the code.
This lays the foundations for future, general LSA refresh improvements,
such as making sequence rollover work, and having generic LSA delays.
* ospfd.h: (struct ospf) Bye bye to the router-lsa update timer thread
pointer.
(struct ospf_area) and to the router-lsa refresh timer.
* ospf_interface.h: Remove the network_lsa_self timer thread pointer
* ospf_lsa.h: (struct ospf_lsa) oi field should always be there, for benefit
of type-2/network LSA processing.
(ospf_{router,network}_lsa_{update_timer,timer_add}) no timers for these
more
(ospf_{router,network}_lsa_update) more generic functions to indicate that some
router/network LSAs need updating
(ospf_router_lsa_update_area) update router lsa in a particular area alone.
(ospf_{summary,summary_asbr,network}_lsa_refresh) replaced by the general
ospf_lsa_refresh function.
(ospf_lsa_refresh) general LSA refresh function
* ospf_interface.h: (struct ospf_if_params) add field for saved network LSA
seqnum
* ospf_interfa.c: (ospf_new_if_params) init network_lsa_seqnum field to
initial seqnum - doesnt matter though.
* ospf_lsa.c: (ospf_network_lsa_new) check for any saved sequence number,
and use if it exists. Save the result back. This should help avoid needless
round of LSUpdate/LSRequests when a neighbour has to tell the originator
"uhm, i have something newer than that already".
* ospf_vty.c: (show_ip_ospf_interface_sub) Show the saved network LSA seqnum
The following syntax forms were not historically supported
by Quagga, although IOS accepted them w/o a problem:

* if.h: (struct connected) Add new ZEBRA_IFA_PEER flag indicating
whether a peer address has been configured. Comment now shows
the new interpretation of the destination addr: if ZEBRA_IFA_PEER
is set, then it must contain the destination address, otherwise
it may contain the broadcast address or be NULL.
(CONNECTED_DEST_HOST,CONNECTED_POINTOPOINT_HOST) Remove obsolete
macros that were specific to IPv4 and not fully general.
(CONNECTED_PEER) New macro to check ZEBRA_IFA_PEER flag.
(CONNECTED_PREFIX) New macro giving the prefix to insert into
the RIB: if CONNECTED_PEER, then use the destination (peer) address,
else use the address field.
(CONNECTED_ID) New macro to come up with an identifying address
for the struct connected.
* if.c: (if_lookup_address, connected_lookup_address) Streamline
logic with new CONNECTED_PREFIX macro.
* prefix.h: (PREFIX_COPY_IPV4, PREFIX_COPY_IPV6) New macros
for better performance than the general prefix_copy function.
* zclient.c: (zebra_interface_address_read) For non-null destination
addresses, set prefixlen to equal the address prefixlen. This
is needed to get the new CONNECTED_PREFIX macro to work properly.
* connected.c: (connected_up_ipv4, connected_down_ipv4,
connected_up_ipv6, connected_down_ipv6) Simplify logic using the
new CONNECTED_PREFIX macro.
(connected_add_ipv4) Set prefixlen in destination addresses (required
by the CONNECTED_PREFIX macro). Use CONNECTED_PEER macro instead
of testing for IFF_POINTOPOINT. Delete invalid warning message.
Warn about cases where the ZEBRA_IFA_PEER is set but no
destination address has been supplied (and turn off the flag).
(connected_add_ipv6) Add new flags argument so callers may set
the ZEBRA_IFA_PEER flag. If peer/broadcast address satisfies
IN6_IS_ADDR_UNSPECIFIED, then reject it with a warning.
Set prefixlen in destination address so CONNECTED_PREFIX will work.
* connected.h: (connected_add_ipv6) Add new flags argument so
callers may set the ZEBRA_IFA_PEER flag.
* interface.c: (connected_dump_vty) Use CONNECTED_PEER macro
to decide whether the destination address is a peer or broadcast
address (instead of checking IFF_BROADCAST and IFF_POINTOPOINT).
* if_ioctl.c: (if_getaddrs) Instead of setting a peer address
only when the IFF_POINTOPOINT is set, we now accept a peer
address whenever it is available and not the same as the local
address. Otherwise (no peer address assigned), we check
for a broadcast address (regardless of the IFF_BROADCAST flag).
And must now pass a flags value of ZEBRA_IFA_PEER to
connected_add_ipv4 when a peer address is assigned.
The same new logic is used with the IPv6 code as well (and we
pass the new flags argument to connected_add_ipv6).
(if_get_addr) Do not bother to check IFF_POINTOPOINT: just
issue the SIOCGIFDSTADDR ioctl and see if we get back
a peer address not matching the local address (and set
the ZEBRA_IFA_PEER in that case). If there's no peer address,
try to grab SIOCGIFBRDADDR regardless of whether IFF_BROADCAST is set.
* if_ioctl_solaris.c: (if_get_addr) Just try the SIOCGLIFDSTADDR ioctl
without bothering to check the IFF_POINTOPOINT flag. And if
no peer address was found, just try the SIOCGLIFBRDADDR ioctl
without checking the IFF_BROADCAST flag. Call connected_add_ipv4
and connected_add_ipv6 with appropriate flags.
* if_proc.c: (ifaddr_proc_ipv6) Must pass new flags argument to
connected_add_ipv6.
* kernel_socket.c: (ifam_read) Must pass new flags argument to
connected_add_ipv6.
* rt_netlink.c: (netlink_interface_addr) Copy logic from iproute2
to determine local and possible peer address (so there's no longer
a test for IFF_POINTOPOINT). Set ZEBRA_IFA_PEER flag appropriately.
Pass new flags argument to connected_add_ipv6.
(netlink_address) Test !CONNECTED_PEER instead of if_is_broadcast
to determine whether the connected destination address is a
broadcast address.
* bgp_nexthop.c: (bgp_connected_add, bgp_connected_delete)
Simplify logic by using new CONNECTED_PREFIX macro.
* 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.
* rip_interface.c: (rip_interface_multicast_set) Use new CONNECTED_ID
macro to simplify logic.
(rip_request_interface_send) Fix minor bug: ipv4_broadcast_addr does
not give a useful result if prefixlen is 32 (we require a peer
address in such cases).
* ripd.c: (rip_update_interface) Fix same bug as above.

(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.

* (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.

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

(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).

table str[]. Replace str[] with calls to new library function
zebra_route_string().
* ripd.c: Remove local hard-coded table route_info[].
(show_ip_rip) Replace uses of str[] with calls to new library
functions zebra_route_char and zebra_route_string.
* ripng_zebra.c: (ripng_redistribute_write) Remove local hard-coded
table str[]. Replace str[i] with new library function
zebra_route_string(i).
* ripngd.c: Remove local hard-coded table route_info[].
(show_ipv6_ripng) Use new library function zebra_route_char() instead
of table route_info[].
* ospfd/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

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

ifp->ifindex to IFINDEX_INTERNAL.
* ripng_interface.c: (ripng_interface_delete) After deleting, set
ifp->ifindex to IFINDEX_INTERNAL.
* ospf_vty.c (show_ip_ospf_interface_sub): Display interface MTU and
bandwidth; this is useful for debugging problems. Also, the function
should be static.
* ospf_interface.h: Improve passive_interface comment. Add new
multicast_memberships bitmask to struct ospf_interface to track
active multicast subscriptions. Declare new function
ospf_if_set_multicast.
* ospf_interface.c: (ospf_if_set_multicast) New function to configure
multicast memberships properly based on the current
multicast_memberships status and the current values of the
ospf_interface state, type, and passive_interface status.
(ospf_if_up) Remove call to ospf_if_add_allspfrouters (this is
now handled by ism_change_state's call to ospf_if_set_multicast).
(ospf_if_down) Remove call to ospf_if_drop_allspfrouters (now
handled by ism_change_state).
* ospf_ism.c: (ospf_dr_election) Remove logic to join or leave
the DRouters multicast group (now handled by ism_change_state's call
to ospf_if_set_multicast).
(ism_change_state) Add call to ospf_if_set_multicast to change
multicast memberships as necessary to reflect the new interface state.
* ospf_packet.c: (ospf_hello) When a Hello packet is received on a
passive interface: 1. Increase the severity of the error message
from LOG_INFO to LOG_WARNING; 2. Add more information to the error
message (packet destination address and interface address);
and 3. If the packet was sent to ospf-all-routers, then try
to fix the multicast group memberships.
(ospf_read) When a packet is received on an interface whose state
is ISM_Down, enhance the warning message to show the packet
destination address, and try to update/fix the multicast group
memberships if the packet was sent to a multicast address.
When a packet is received for ospf-designated-routers, but the
current interface state is not DR or BDR, then increase the
severity level of the error message from LOG_INFO to LOG_WARNING,
and try to fix the multicast group memberships.
* ospf_vty.c: (ospf_passive_interface) Call ospf_if_set_multicast for
any ospf interface that may have changed from active to passive.
(no_ospf_passive_interface) Call ospf_if_set_multicast for
any ospf interface that may have changed from passive to active.
(show_ip_ospf_interface_sub) Show multicast group memberships.
* 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.
* (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.
* ospf_vty.c: (global) add, unused, description array for lsa flags.
(show_ip_ospf_database_header): pretty print options, printf hex
numbers as 0x, print lsa flags and note if it is a translated LSA.
(show_lsa_detail_proc): print out OSPF_LSA_LOCAL_XLT LSAs.
* ospf_packet.c: (ospf_write) print out destination IP in debug info
if write fails.

(ospf_area_nssa_cmd_handler): new function to handle the
area.*nssa commands.
(ospf_area_nssa_cmd): changed to call ospf_area_nssa_cmd_handler
(ospf_area_nssa_translate_cmd) ditto
(ospf_area_nssa_translate_cmd): changed from ALIAS to defun, call
ospf_area_nssa_cmd_handler
(ospf_area_nssa_translate_no_summary_cmd): ditto
(no_ospf_area_nssa_cmd): call ospf_schedule_abr_task()
(show_ip_ospf_area): Formatting cleanups. Properly print out NSSA
area configuration.

Add the 'no interface' command to all the daemons and vtysh. now it's
possible to delete interface from routeing daemons as well only if it
doesn't exist in os.
http://hasso.linux.ee/zebra/ht-no_interface_fix.patch
