Just use the same style for all `DEFPY`s. It is a cosmetic change, doesn't
affect the actual function.

Replace the LSDB callbacks with LSA update and delete hooks using the
the FRR hook mechanism. Remove redundant callbacks by placing the LSA
update and delete hooks in a single place so that deletes don't need
to be handled by the update hook. Simplify existing OSPF TE and OSPF
API Server callbacks now that there is no ambiguity or redundancy.
Also cleanup the debugging by separating out opaque-lsa debugging
from the overloaded event debugging.

Coverity 2024 new hotness
|
|
Duplicate next-hops are maintained for OSPF inter-area and AS
external routes in the OSPF routing table as long as they
correspond to LSAs for different adverting routers. The
intra-area route computation will not result in duplicate
next-hops.

msg_new takes a uint16_t, the length passed
down variable is a unsigned int, thus 32 bit.
It's possible, but highly unlikely, that the
msglen could be greater than 16 bit.
Let's just add some checks to ensure that
this could not happen.

Since the timer thread for ```OSPF_ROUTE_AGGR_DEL``` has been created,
the subsequent "no summary-address" commands shouldn't trigger redundant timers.

When OSPFd starts, there is 2 possible scenarios for Segment Routing:
1/ Routes associated to Prefixes are not yet available i.e. Segment Routing LSA
are received before LSA Type 1. In this case, the function
ospf_sr_nhlfe_update() is triggered when a new SPF is launch. Thus, neighbors
and output label are always synchronise with the routing table.
2/ Routes are already available i.e. LSA Type 1 are received before Segment
Routing LSA, in particular the Router Information which contains the SRGB.
During nhlfe computation, perfixes are leave with incomplete configuration, in
particular, the SR nexthop is set to NULL. If this scenario is handle through
the function update_out_nhlfe (triggered when SRGB is received or modified from
a neighbor node), the output label is not correctly configured as the nexthop
SR node associated to the prefix has been leave to NULL.
This patch correct this problem by calling the function compute_nhlfe() when
the nexthop SR Node associated to the prefix is NULL within the
update_out_nhlfe() function. Thus, we guarantee that the SR prefix is always
correctly configuration indpedently of the scenario i.e. arrival of the
different LSA.

When originating a default AS-External LSA in one OSPF instance,
it wasn't working if the criteria route was installed by another OSPF
instance. This required more flexible processing of the OSPF external
route information.
Also fix problem multi-instance display for "show ip ospf
<instance> database ...".

ospfd: Fix assert in LSA refresh interval setting

|
ospfd: Use router_id what Zebra has if we remove a static router_id
|
|
Under certain timing conditions, the current logic asserts in
ospf_lsa_refresh_delay(). While this isn't readily reproducible,
the only explanation is that the conversion from struct timeval
to milliseconds is 0 due to rounding off the microseconds.

LabNConsulting/aceelindem/ospf-ls-refresh-interval-fix
ospfd: Fix opaque LSA refresh interval and modify LSA cmds.
|
|
This reverts commit 71aa5ab7f6f166065e3b869e3c33ba5b7a57fccb.
|
|
If we set router-id, e.g. `router-id x.x.x.x`, then we have:
```
pc.donatas.net# show ip ospf | include Router ID
OSPF Routing Process, Router ID: x.x.x.x
```
But once we remove it (`no router-id x.x.x.x`), the old router-id remains.
This is kinda OK, but to be consistent with OSPFv3 we should use what Zebra
already has, instead of retaining the old one.

ospfd:fix syntax of some ospf no commands
|
|
The configured OSPF refresh interval was not being used for opaque LSA (it always used the constant). Also, modified the timers lsa min-arrival command to have a maximum of 5000 msecs as well as providing a path for backward command compatibility.
Added missing user documentation for both timers lsa min-arrival and timers throttle lsa all.

2. `no area nssa default-information-originate metric <NUM>`, `<NUM>` can be omitted.
3. `no area nssa range cost <NUM>`, `<NUM>` can be omitted.
4. `no area default cost <NUM>`, `<NUM>` can be omitted.
5. `no ospf write-multiplier <NUM>`, `<NUM>` can be omitted.
6. `no default-information originate metric <NUM>`, `<NUM>` can be omitted.
7. `no distance <NUM>`, `<NUM>` can be omitted.

command was executed
When we use the no area X.X.X.X range A.B.C.D/M command, if the area no longer has an interface to which it belongs, then the area should be deleted from the LSDB. This processing logic is consistent with instructions such as no network area and no area authentication.

ospfd: update ospf_asbr_status when using no_area_nssa command
|
|
In the processing of nssa, if the number of areas that need to be translated is greater than 0, then abr will be regarded as asbr, and it will be marked (0x3) in the flag of router lsa. When a certain area is set from nssa to a normal area, the areas that need to be translated may be reduced. The asbr should be re-interpreted as abr when the translated area is 0.

Our standard says when in a .h file and declaring a function all parameters
must have their variables spelled out. Let's do this for ospf_lsa.h
Modified ospf_lsa.c to also use event instead of thread, and uint8_t instead
of unsigned short.

When "ip ospf network point-to-multipoint delayed-reflooding" is configured,
LSAs received on an OSPF P2MP network are not reflooded. Since LSA reflooding
would normally serve as an implied LSA acknowledgment, an explicit OSPF ack
should be sent to avoid retransmission by the neighbor which orginally flooded
the LSA on the P2MP network.
