Add the "default-information-originate" option to the "area X nssa"
command. That option allows the origination of Type-7 default routes
on NSSA ABRs and ASBRs.

RFC 3623 specifies the Graceful Restart enhancement to the OSPF
routing protocol. This PR implements support for the restarting mode,
whereas the helper mode was implemented by #6811.
This work is based on #6782, which implemented the pre-restart part
and settled the foundations for the post-restart part (behavioral
changes, GR exit conditions, and on-exit actions).
Here's a quick summary of how the GR restarting mode works:
* GR can be enabled on a per-instance basis using the `graceful-restart
[grace-period (1-1800)]` command;
* To perform a graceful shutdown, the `graceful-restart prepare ospf`
EXEC-level command needs to be issued before restarting the ospfd
daemon (there's no specific requirement on how the daemon should
be restarted);
* `graceful-restart prepare ospf` will initiate the graceful restart
for all GR-enabled instances by taking the following actions:
o Flooding Grace-LSAs over all interfaces
o Freezing the OSPF routes in the RIB
o Saving the end of the grace period in non-volatile memory (a JSON
file stored in `$frr_statedir`)
* Once ospfd is started again, it will follow the procedures
described in RFC 3623 until it detects it's time to exit the graceful
restart (either successfully or unsuccessfully).
Testing done:
* New topotest featuring a multi-area OSPF topology (including stub
and NSSA areas);
* Successful interop tests against IOS-XR routers acting as helpers.

Currently ospfd relies on vrf bitmaps in zclient to check that the
redistribution is configured. This doesn't work when the VRF for OSPF
instance doesn't exist yet, because vrf bitmaps ignore VRF_UNKNOWN id.
Because of this, the following problems occur when the VRF doesn't exist:
- repeated "redistribute smth" command is processed as a first-time
instead of an update
- "no redistribute smth" doesn't work at all
This commit fixes both issues by relying on internal redistribution
config instead of zclient vrf bitmaps.

Currently, ospf external routers are part of struct
ospf_master which is not vrf aware ospf instance.
All ospf external routes are injected/leaked into all
vrfs.
Moved ospf external routes db to struct ospf to make
vrf aware, such one external routes learnt in one vrf
is not leaked into another vrf.
Ticket:CM-18855
Testing Done:
Inject external route in non-default vrf x, validated
ospf database across the vrf x, validated ospf routes
for vrf x.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

zclient.c depended upon link time inclusion of a
extern struct thread_master *master. This is a violation of the
namespace of the calling daemon. If a library needs the pointer
pass it in and save it for future use.
This code change also makes the zclient code consistent with
the other lib functions that need to schedule work on your behalf

——————————————-------------
- 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
some of the modified APIs/routines. (Didn’t prefer replicating too many
separate instance specific APIs.)
- config/show/debug commands are modified to take instance-id argument
as appropriate.
Guidelines to start using multi-instance ospf
---------------------------------------------
The patch is backward compatible, i.e for any previous way of single ospf
deamon(router ospf <cr>) will continue to work as is, including all the
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.c: (ospf_new) stub-shutdown should just default to
unconfigured, too strange otherwise.
(ospf_finish_final) t_opaque_lsa_self TIMER_OFF should be
preprocessor conditional on HAVE_OPAQUE_LSA.
* ospfd.h: (struct ospf) remove the SHUTDOWN_DEFAULT define.
no longer used, plus it wasn't in range that the command
accepted.
* ospf_zebra.h: Depends on vty.h, include it.
|
|
* (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) 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.
