1. Fix OSPF opaque LSA processing to preserve the stale opaque
LSAs in the Link State Database for 60 seconds consistent with
what is done for other LSA types.
2. Add a topotest that tests for cases where ospfd is restarted
and a stale OSPF opaque LSA exists in the OSPF routing domain
both when the LSA is purged and when the LSA is reoriginagted
with a more recent instance.

This command makes unplanned GR more reliable by manipulating the
sending of Grace-LSAs and Hello packets for a certain amount of time,
increasing the chance that the neighboring routers are aware of
the ongoing graceful restart before resuming normal OSPF operation.
Signed-off-by: Renato Westphal <renato@opensourcerouting.org>
In practical terms, unplanned GR refers to the act of recovering
from a software crash without affecting the forwarding plane.
Unplanned GR and Planned GR work virtually the same, except for the
following difference: on planned GR, the router sends the Grace-LSAs
*before* restarting, whereas in unplanned GR the router sends the
Grace-LSAs immediately *after* restarting.
For unplanned GR to work, ospf6d was modified to send a
ZEBRA_CLIENT_GR_CAPABILITIES message to zebra as soon as GR is
enabled. This causes zebra to freeze the OSPF routes in the RIB as
soon as the ospfd daemon dies, for as long as the configured grace
period (the defaults is 120 seconds). Similarly, ospfd now stores in
non-volatile memory that GR is enabled as soon as GR is configured.
Those two things are no longer done during the GR preparation phase,
which only happens for planned GRs.
Unplanned GR will only take effect when the daemon is killed
abruptly (e.g. SIGSEGV, SIGKILL), otherwise all OSPF routes will
be uninstalled while ospfd is exiting. Once ospfd starts, it will
check whether GR is enabled and enter in the GR mode if necessary,
sending Grace-LSAs out all operational interfaces.
One disadvantage of unplanned GR is that the neighboring routers
might time out their corresponding adjacencies if ospfd takes too
long to come back up. This is especially the case when short dead
intervals are used (or BFD). For this and other reasons, planned
GR should be preferred whenever possible.

When using route maps with external routes in OSPF as follows:
```
set metric +10
```
The current behavior is to use the default ospf metric as the base and then add
to 10 to it. The behavior isn't useful as-is. A value 30 (20 dfeault + 10) can
be set directly instead. the behavior is also not consistent with bgp. bgp does
use the rib metric in this case as the base. The current behavior also doesn't
allow the metric to accumulate when crossing different routing domains such as
vrfs causing the metric to reset every time the route enters a new vrf with a new
ospf network.
This PR changes the behavior such that the rib metric is used as a base for
ospf exteral routes when used with `set metric -/+`

Implement NSSA address ranges as specified by RFC 3101:
NSSA border routers may be configured with Type-7 address ranges.
Each Type-7 address range is defined as an [address,mask] pair. Many
separate Type-7 networks may fall into a single Type-7 address range,
just as a subnetted network is composed of many separate subnets.
NSSA border routers may aggregate Type-7 routes by advertising a
single Type-5 LSA for each Type-7 address range. The Type-5 LSA
resulting from a Type-7 address range match will be distributed to
all Type-5 capable areas.
Syntax:
area A.B.C.D nssa range A.B.C.D/M [<not-advertise|cost (0-16777215)>]
Example:
router ospf
router-id 1.1.1.1
area 1 nssa
area 1 nssa range 172.16.0.0/16
area 1 nssa range 10.1.0.0/16

this commit reuses the existing infrastructure for area ranges as
much as possible to avoid code duplication.

Whenever OSPF virtual-link is created, a virtual interface is
associated with it. Name of the virtual interface is derived by
combining "VLINK" string with the value of vlink_count, which is a global
variable.
Problem:
Consider a scenario where 2 virtual links A and B are created in OSPF with
virtual interfaces VLINK0 and VLINK1 respectively. When virtual-link A is unconfigured
and reconfigured, new interface name derived for it will be VLINK1, which is already
associated with virtual-link B. Due to this, both virtual-links A and B will
point to the same interface, VLINK1.
During FRR restart when signal handler is called, OSPF goes through all the virtual
links and deletes the interface(oi) associated with it. During the deletion of interface
for virtual-link B,it accesses the interface which was deleted already(which was deleted
during deletion of virual-link A) and whose fields were set to NULL. This
leads to OSPF crash.
Fixed it by not decrementing vlink_count during unconfig/deletion for virtual-link.

As it can be seen below, the LSDB JSON output varies depending
whether a filter option is specified or not (e.g. "adv-router",

This inconsistency is undesirable since it makes this data harder to
consume programmatically. Also, in the second output, "Router Link
States" is used as a JSON key, which doesn't conform to our JSON
guidelines (JSON keys need to be camelCased).

`ospf_nexthop_calculation`. Instead allocate a new copy so it can be
`free()`d later without complications

Description:
As part of signal handler ospf_finish_final(), lsas are originated
and added to refresh queues are not freed.
One such leak is :

Steps to reproduce:
--------------------------
1. ANVL: Establish full adjacency with DUT for neighbor Rtr-0-A on DIface-0 with DUT as DR.
2. ANVL: Listen (for up to 2 * <RxmtInterval> seconds) on DIface-0.
3. DUT: Send <OSPF-LSU> packet.
4. ANVL: Verify that the received <OSPF-LSU> packet contains a Network- LSA for network N1
originated by DUT, and the LS Sequence Number is set to <InitialSequenceNumber>.
5. ANVL: Establish full adjacency with DUT for neighbor Rtr-0-B on DIface-0 with DUT as DR.
6. ANVL: Listen (for up to 2 * <RxmtInterval> seconds) on DIface-0.
7. DUT: Send <OSPF-LSU> packet.
8. ANVL: Verify that the received <OSPF-LSU> packet contains a new instance of the
Network-LSA for network N1 originated by DUT, and the LS Sequence Number
is set to (<InitialSequenceNumber> + 1).
Both the test cases were failing while verifying the initial sequence number for network LSA.
This is because currently OSPF does not reset its LSA sequence number when it is going down.

OSPF_MAX_LSA_SIZE does not represent the actual maximum size of LSA packets which may be larger than 1500 bytes. If relaying a large OSPF packet to the OSPF API, we do not allocate a big enough buffer to send over the API. This patch increases the maximum size of OSPF packets transmitted over the API.

Rather than running selected source files through the preprocessor and a
bunch of perl regex'ing to get the list of all DEFUNs, use the data
collected in frr.xref.
This not only eliminates issues we've been having with preprocessor
failures due to nonexistent header files, but is also much faster.
Where extract.pl would take 5s, this now finishes in 0.2s. And since
this is a non-parallelizable build step towards the end of the build
(dependent on a lot of other things being done already), the speedup is
actually noticeable.
Also files containing CLI no longer need to be listed in `vtysh_scan`
since the .xref data covers everything. `#ifndef VTYSH_EXTRACT_PL`
checks are equally obsolete.

Currently this running config depends at least one `area` with *active*
`network`, otherwise it will not occur.
The check on this dependency is redundant and wrong, just remove it.

FRR implements a non-standard, but compatible approach for
sending update LSAs (it always send to 224.0.0.5) on P2MP
interfaces. This change makes it so acks are also sent to
224.0.0.5.
Since the acks are multicast, this allows an optimization
where we don't send back out the incoming P2MP interface
immediately allow time to rx multicast ack from neighbors
on the same net that rx'ed the original (multicast) update.

When forming a neighbor relationship on an interface, ospf is
currently evaluating unnumbered as highest priority, without
any consideration for if you have /32's and non /32's on the
interface. Effectively if I have something like this:
int foo0
ip address 192.168.119.1/24
!
router ospf
network 0.0.0.0/0 area 0
!
ospf will form a neighbor on foo0 if it exists. Now
suppose someone does this:
int foo0
ip address 192.168.120.1/32
This will create the unnumbered interface on foo0 and
the peering will come down immediately.
The problem here is that the original designers of the unnumbered
code for ospf didn't envision end operators mixing and matching
addresses on an interface like this ( for perfectly legitimate
reasons I might add ).
So if ospf has both numbered and unnumbered let's match against
the numbered first and then unnumbered. This solves the problem
