`same_attr` has been computed and `hook_call(bgp_process)` (calling
BMP module) would not change it. We could reuse the value to filter
same attribute updates, avoiding an extra comparison.

On looking at bgp_bfd_dest_update the function call into bfd_get_peer_info
when it fails to lookup the ifindex ifp pointer just returns leaving
the dest and src prefix pointers pointing to whatever was passed in.
Let's do two things:
a) The src pointer was sometimes assumed to be passed in and sometimes not.
Forget that. Make it always be passed in
b) memset the src and dst pointers to be all zeros. Then when we look
at either of the pointers we are not making decisions based upon random
data in the pointers.

Issue:
The rpki subcontext uses exit instead of end to exit.
This makes issues with frr-reload in the way that frr-reload never exits
rpki context until it reaches the next end statement. this also happens when
parsing the configuration from vtysh.

BFD key has optional fields "local" and "ifname" which can be empty when
the BFD session is created. In this case, the hash key will be calculated
with these fields filled with zeroes.
Later, when we're looking for the BFD session using the key with fields
"local" and "ifname" populated with actual values, the hash key will be
different. To work around this issue, we're doing multiple hash lookups,
first with full key, then with fields "local" and "ifname" filled with
zeroes.
But there may be another case when the initial key has the actual values
for "local" and "ifname", but the key we're using for lookup has empty
values. This case is covered for IPv4 by using additional hash walk with
bfd_key_lookup_ignore_partial_walker function but is not covered for IPv6.
Instead of introducing more hacks and workarounds, the following solution
is proposed:
- the hash key is always calculated in bfd_key_hash_do using only
required fields
- the hash data is compared in bfd_key_hash_cmp, taking into account the
fact that fields "local" and "ifname" may be empty
Using this solution, it's enough to make only one hash lookup.

Care was taken to keep this documentation as generic as possible so

An UPDATE message that contains the AS number of zero in the AS_PATH
or AGGREGATOR attribute MUST be considered as malformed and be
handled by the procedures specified in [RFC7606].
An UPDATE message with a malformed AGGREGATOR attribute SHALL be
handled using the approach of "attribute discard".
Attribute discard: In this approach, the malformed attribute MUST
be discarded and the UPDATE message continues to be processed.
This approach MUST NOT be used except in the case of an attribute
that has no effect on route selection or installation.
