The restricting of data about interfaces was both inconsistent
in application and allowed protocol developers to get into states where
they did not have the expected data about an interface that they
thought that they would. These restrictions and inconsistencies
keep causing bugs that have to be sorted through.
The latest iteration of this bug was that commit:
f20b478ef3
Has caused pim to not receive interface up notifications( but
it knows the interface is back in the vrf and it knows the
relevant ip addresses on the interface as they were changed
as part of an ifdown/ifup cycle ).
Remove this restriction and allow the interface events to
be propagated to all clients.

Made changes and updated the routemap applied counter in the following flows.
1.Increment when route map attached to a list.
2.Decrement when route map removed / modified from a list.
3.Increment/decrement when route map create/delete callback triggered.
4.Besides ,This counter need not be updated when a route map is got updated.
i.e changing/adding a match value to the existing routemap.
In BGP , same update api called for all three add/delete/update operation .
But this counter have to be updated only for routemap addition.
Addressed this specific change by identifying the routemap operation based
on routemap pointer.

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.

Made the following changes.
1.Defined two apis in routemap-lib, one for increment and another for
decrement the applied counter.
2.Added a new configuration “show route-map-unused” to track all unused
routemaps.
3.called the corresponding route map update api when a route map attached
or detached from any redistribution list.

we are still not behaving quite correctly on
handling routes we have learned from those peers

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).

The master thread handler is really part of the zrouter structure.
So let's move it over to that. Eventually zserv.h will only be

When we get into rib_process_result and the operation we are handling
is DPLANE_OP_ROUTE_UPDATE *and* the route entry being looked at
is a route replace, we currently have no way to decode to the old_re
and the re due to how we have stored context. As such they are the
same pointer.
As such the route replace for the same route type is causing the re
to set the installed flag and then immediately unset the installed
flag, leaving us in a state where the kernel has the route but
the rib thinks we are not installed.
Since the true old_re( the one being replaced by the update operation )
is going away( as that it zebra deletes the old one for us already )
this fix is not optimal but will get us moving forward.
