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.

Made changes and updated the routemap applied counter in the following flows.
1.Increment the routemap applied counter when route map attached to a
redistribution list. The counter will be updated if the routemap exists.
2.Decrement when route map removed / modified from a redistribution list.
3.Increment/decrement when route map create/delete callback triggered.

Based on the vulnerability mentioned in 793496 an attacker can craft an
LSA with MaxSequence number wtih invalid links and not set age to MAX_AGE
so the lsa would not be flush from the database.
To address the issue, check incoming LSA is MaxSeq but Age is not set
to MAX_AGE 3600, discard the LSA from processing it.
Based on RFC-2328 , When a LSA update sequence reaches MaxSequence
number, it should be prematurely aged out from the database with age set
to MAX_AGE (3600).

Ospfd cored because of an assert when we try to write more than the MTU
size to the ospf packet buffer stream. The problem is - we allocate only MTU
sized buffer. The expectation is that Hello packets are never large
enough to approach MTU. Instead of crashing, this fix discards hello and
logs an error. One should not have so many neighbors behind an
interface.

the command was not checking
correctly in all cases whether the virtual link existed. This caused
bugs in some corner cases, e.g. when two virtual links were created,
one of them was deleted, and the second one was reset with no
authentication - this would instead create a new virtual link with
the area in decimal format.

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.

Router Information needs to specify the area ID when flooding scope is set to
AREA. However, this authorize only one AREA. Thus, Area Border Router (ABR) are
unable to flood Router Information Opaque LSA in all areas they are belongs to.
The path implies that the area ID is no more necessary for the command
'router-info area'. It remains suported for compatibility, but mark as
deprecated. Documentation has been updated accordingly.

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
YANG language. We must also ensure that only inactive interfaces can be
removed, among other things we need to validate in the northbound layer.
