- touching the LSDB to explicitly remove a MaxAge LSA is always wrong
and results in desynchronization of the entire routing domain
- the LSDB code correctly handles replacing a MaxAge LSA with a newly

- removing the old LSA resets the sequence numbers, which may cause
other routers to reject the new LSA as old

Introducing a 3rd state for route_map_apply library function: RMAP_NOOP
Traditionally route map MATCH rule apis were designed to return
a binary response, consisting of either RMAP_MATCH or RMAP_NOMATCH.
(Route-map SET rule apis return RMAP_OKAY or RMAP_ERROR).
Depending on this response, the following statemachine decided the
course of action:
State1:
If match cmd returns RMAP_MATCH then, keep existing behaviour.
If routemap type is PERMIT, execute set cmds or call cmds if applicable,
otherwise PERMIT!
Else If routemap type is DENY, we DENYMATCH right away
State2:
If match cmd returns RMAP_NOMATCH, continue on to next route-map. If there
are no other rules or if all the rules return RMAP_NOMATCH, return DENYMATCH
We require a 3rd state because of the following situation:
The issue - what if, the rule api needs to abort or ignore a rule?:
"match evpn vni xx" route-map filter can be applied to incoming routes
regardless of whether the tunnel type is vxlan or mpls.
This rule should be N/A for mpls based evpn route, but applicable to only
vxlan based evpn route.
Also, this rule should be applicable for routes with VNI label only, and
not for routes without labels. For example, type 3 and type 4 EVPN routes
do not have labels, so, this match cmd should let them through.
Today, the filter produces either a match or nomatch response regardless of
whether it is mpls/vxlan, resulting in either permitting or denying the
route.. So an mpls evpn route may get filtered out incorrectly.
Eg: "route-map RM1 permit 10 ; match evpn vni 20" or
"route-map RM2 deny 20 ; match vni 20"
With the introduction of the 3rd state, we can abort this rule check safely.
How? The rules api can now return RMAP_NOOP to indicate
that it encountered an invalid check, and needs to abort just that rule,
but continue with other rules.
As a result we have a 3rd state:
State3:
If match cmd returned RMAP_NOOP
Then, proceed to other route-map, otherwise if there are no more
rules or if all the rules return RMAP_NOOP, then, return RMAP_PERMITMATCH.

otherwise we PERMIT!
Else: If Routemap type is DENY, we DENYMATCH right away
State2: Received RMAP_NOMATCH, continue on to next route-map, otherwise,
return DENYMATCH by default if nothing matched.
With reference to PR 4078 (https://github.com/FRRouting/frr/pull/4078),
we require a 3rd state because of the following situation:
The issue - what if, the rule api needs to abort or ignore a rule?:
"match evpn vni xx" route-map filter can be applied to incoming routes

How? The rules api can now return RMAP_NOOP (or another enum) to indicate
that it encountered an invalid check, and needs to abort just that rule,
but continue with other rules.
Question: Do we repurpose an existing enum RMAP_OKAY or RMAP_ERROR
as the 3rd state (or create a new enum like RMAP_NOOP)?
RMAP_OKAY and RMAP_ERROR are used to return the result of set cmd.
We chose to go with RMAP_NOOP (but open to ideas),
as a way to bypass the rmap filter
As a result we have a 3rd state:
State3: Received RMAP_NOOP

bfd cbit is a value carried out in bfd messages, that permit to keep or
not, the independence between control plane and dataplane. In other
words, while most of the cases plan to flush entries, when bfd goes
down, there are some cases where that bfd event should be ignored. this
is the case with non stop forwarding mechanisms where entries may be
kept. this is the case for BGP, when graceful restart capability is
used. If BFD event down happens, and bgp is in graceful restart mode, it
is wished to ignore the BFD event while waiting for the remote router to
restart.
The changes take into account the following:
- add a config flag across zebra layer so that daemon can set or not the
cbit capability.
- ability for daemons to read the remote bfd capability associated to a bfd
notification.
- in bfdd, according to the value, the cbit value is set
- in bfdd, the received value is retrived and stored in the bfd session
context.
- by default, the local cbit announced to remote is set to 1 while
preservation of the local path is not set.

The order of ECMP nexthops currently depends on whatever order the
pqueue code returns the vertices in, which is essentially random since
they compare as equal. While this shouldn't cause issues normally, it
is nondeterministic and causes the ldp-topo1 test to fail when the
ordering comes up different. Also, nondeterministic behaviour is not a
nice thing to have here in general.
Just sort by nexthop address; realistic numbers of ECMP nexthops should
hopefully not make this a performance issue. (Also, nexthops should be
hot in the caches here.)

OSPFD uses -1 as a sentinel value for uninitialized metrics. When
applying a route map with a +/-metric to redistributed routes, we were
using -1 as our base value to increment or decrement on, which meant
that if you set e.g. +10, you would end up with a redistributed route of
metric 9.
This patch also removes an off-by-one sanity check that would cause a
set metric +1 or set metric 0 to result in a metric value of 20 :-)

While fragmenting ospf ls packets, before appending the link state info,
wrong value is checked to see if current packet can fit in another ls info.
Because of this, when a lower mtu is configured, it couldn't fit in even 1
ls ack, which tries to send all the available ls ack in the list in loop.
This keeps allocating memory to send the packet and ends up putting the
packet buffer without ls-ack into deferred send que(ospf_ls_ack_send_delayed).
This infinite loop causes infinite memory being allocated in a loop causing
system to be unstable. This commit takes care of calculating the right value
to compare for checking oif this buffer can fit in more.

To address the issue, check incoming LSA is MaxSeq but Age is not set

Based on RFC-2328 , When a LSA update sequence reaches MaxSequence

Some daemons like ospfd and isisd have the ability to advertise a
default route to their peers only if one exists in the RIB. This
is what the "default-information originate" commands do when used
without the "always" parameter.
For that to work, these daemons use the ZEBRA_REDISTRIBUTE_DEFAULT_ADD
message to request default route information to zebra. The problem
is that this message didn't have an AFI parameter, so a default route
from any address-family would satisfy the requests from both daemons
(e.g. ::/0 would trigger ospfd to advertise a default route to its
peers, and 0.0.0.0/0 would trigger isisd to advertise a default route
to its IPv6 peers).
Fix this by adding an AFI parameter to the
ZEBRA_REDISTRIBUTE_DEFAULT_{ADD,DELETE} messages and making the
corresponding code changes.

The frr-interface YANG module models interfaces using a YANG list keyed
by the interface name and the interface VRF. Interfaces can't be keyed
only by their name since interface names might not be globally unique
when the netns VRF backend is in use. When using the VRF-Lite backend,
however, interface names *must* be globally unique. In this case, we need
to validate the uniqueness of interface names inside the appropriate
northbound callback since this constraint can't be expressed in the

We had an assert(node) in ospf_write, which means that the list was empty. So I just
searched until I saw a code path that allowed multiple writes to the ospf_write function.

The ->hash_cmp and linked list ->cmp functions were sometimes
being used interchangeably and this really is not a good
thing. So let's modify the hash_cmp function pointer to return
a boolean and convert everything to use the new syntax.

Issue: # https://github.com/FRRouting/frr/issues/1836
Issue 1: if the router ospf current configuration is "area 0.0.0.2
range 1.0.0.0/24 cost 23" and user try to configure "area 0.0.0.2
range 1.0.0.0/24 not-advertise", the existing o/p is "area 0.0.0.2
range 1.0.0.0/24 cost 23 not-advertise". The keywords "not-advertise"
& "cost" are multually exclusive, so they should not come together.
The vice versa way configuration is working fine.
Fix: When ospf area range "not-advertise", the cost should be initialized
to OSPF_AREA_RANGE_COST_UNSPEC.
Issue 2: if the router ospf current configuration "area 0.0.0.2 range
1.0.0.0/24 substitute 2.0.0.0/24" and user try to configure "area 0.0.0.2
range 1.0.0.0/24 not-advertise" the existing o/p is "area 0.0.0.2 range
1.0.0.0/24 not-advertise substitute 2.0.0.0/24". The keywords
"not-advertise" & "substiture" are multually exclusive, so they should
not come together. The vice versa way configuration is working fine.
Fix: When ospf area range "not-advertise" is configured,
ospf_area_range_substitute_unset() should be get called.
Issue 3: if the router ospf6 current configuration is "area 0.0.0.2
range 2001::/64 cost 23" and user try to configure "area 0.0.0.2 range
2001::/64 advertise", the existing o/p is area 0.0.0.2 range 2001::/64.
The keyword "cost 23" disappears.
Fix: When ospf area range "advertise" is configured and the range is not
NULL, the cost should not be modified.

The head and tail pointers of linked lists should never be modified
manually, the linked list API guarantees that these pointers are always
valid and up-to-date.

Since we're now building through one large Makefile, we can easily put
things with their daemons and crossreference nicely.

If we detect we already have a neighbor, no need to
re-add so no need to warn since we do not do anything with
