The above leak detected by valgrind was from a screenshot so I copied it
by hand. Any mistakes in line numbers are purely from my transcription.
Additionally this is against a slightly modified 8.5.1 version of FRR.
Code inspection of 8.5.1 -vs- latest master shows the same problem
exists. Code should be able to be followed from there to here.
What is happening:
There is a route-map being applied that modifes the outgoing community
to a peer. This is saved in the attr copy created in
subgroup_process_announce_selected. This community pointer is not
interned. So the community->refcount is still 0. Normally when
a prefix is announced, the attr and the prefix are placed on a
adjency out structure where the attribute is interned. This will
cause the community to be saved in the community hash list as well.
In a non-normal operation when the decision to send is aborted after
the route-map application, the attribute is just dropped and the
pointer to the community is just dropped too, leading to situations
where the memory is leaked. The usage of bgp suppress-fib would
would be a case where the community is caused to be leaked.
Additionally the previous commit where an unsuppress-map is used
to modify the outgoing attribute but since unsuppress-map was
not considered part of outgoing policy the attribute would be dropped as
well. This pointer drop also extends to any dynamically allocated
memory saved by the attribute pointer that was not interned yet as well.
So let's modify the return case where the decision is made to
not send the prefix to the peer to always just flush the attribute
to ensure memory is not leaked.

Handle ORF REMOVE_ALL events as well, because now we just silently return, and
a stale dynamic prefix-list is used instead of the new one.
Before this, soft clear/route refresh was needed. Don't know the reason, but
we didn't send updates when modifying the filters.
Probably due to a massive change of filters and to avoid automatic updates :/

Description:
Change is intended for fixing the inconsistencies present
while adjusting the SNT counters with default originate.
- SNT counter gets incremented on every change of policy associated
with default-originate, leading to inconsistencies.
- This fix has been added to ensure that the SNT counters gets
incremented and decremented only once during the creation and
deletion workflow of default-originate, and prevents
incrementing the counter during update flow.

Abstract:
- The command "neighbor PEER maximum-prefix-out NUMBER" cannot be applied
without clearing the BGP neighbor.
- Apply the maximum-prefix-out value as soon as it is modified without
clearing the neighbor.
subgroup_update_packet() and subgroup_withdraw_packet() respectively
manages the announcement and withdrawal BGP message to the peer.
subgrp->scount counter counts the number of sent prefixes.
Before the patch, the maximum out prefix limitation was applied in
subgroup_update_packet() in order that subgrp->scount never exceeds the
limit. Setting a limit inferior to the effective number of sent prefix
did not result in sending any withdrawal message to reduce the number of
sent prefixes. Without clearing the BGP neighbor, the limitation only
applied to the announcement of new prefixes when the limitation was
over.
With the patch, the limitation is checked in subgroup_announce_check().
The function is intended to say whether a prefix has to be announced in
regards to the prefix-list, route-map... Now when a maximum-prefix-out
value is changed/removed, the neighbor AFI/SAFI table is re-parsed in
the same way as for the application of route-map, prefix-lists...

3. x1 filters all communities at the egress to c1.
4. Shutdown the link between y1 and y2.
5. y1 will generate a BGP UPDATE message regarding the next-hop change.
6. x1 will generate a BGP UPDATE message regarding community change.
To avoid sending duplicate BGP UPDATE messages we should make sure
we send only actual route updates. In this example, x1 will skip
BGP UPDATE to c1 because the actual route is the same
(filtered communities - nothing changes).

updgrp_hash_key_make() uses the PEER_UPDGRP_AF_FLAGS for the key.
PEER_UPDGRP_AF_FLAGS contains the neigbor flags.
If user do no neighbor <> send community large, then the hash key
does not change and BGP does not send update for large community change.
Added the PEER_FLAG_SEND_LARGE_COMMUNITY in PEER_UPDGRP_AF_FLAGS.
After this the hash key gets changed and update will be processed
with large community.

The motivation for this patch is to address a concerning behavior of
tx-addpath-bestpath-per-AS. Prior to this patch, all paths' TX ID was
pre-determined as the path was received from a peer. However, this meant
that any time the path selected as best from an AS changed, bgpd had no
choice but to withdraw the previous best path, and advertise the new
best-path under a new TX ID. This could cause significant network
disruption, especially for the subset of prefixes coming from only one
AS that were also communicated over a bestpath-per-AS session.
The patch's general approach is best illustrated by
txaddpath_update_ids. After a bestpath run (required for best-per-AS to
know what will and will not be sent as addpaths) ID numbers will be
stripped from paths that no longer need to be sent, and held in a pool.
Then, paths that will be sent as addpaths and do not already have ID
numbers will allocate new ID numbers, pulling first from that pool.
Finally, anything left in the pool will be returned to the allocator.
In order for this to work, ID numbers had to be split by strategy. The
tx-addpath-All strategy would keep every ID number "in use" constantly,
preventing IDs from being transferred to different paths. Rather than
create two variables for ID, this patch create a more generic array that
will easily enable more addpath strategies to be implemented. The
previously described ID manipulations will happen per addpath strategy,
and will only be run for strategies that are enabled on at least one
peer.
Finally, the ID numbers are allocated from an allocator that tracks per
AFI/SAFI/Addpath Strategy which IDs are in use. Though it would be very
improbable, there was the possibility with the free-running counter
approach for rollover to cause two paths on the same prefix to get
assigned the same TX ID. As remote as the possibility is, we prefer to
not leave it to chance.
This ID re-use method is not perfect. In some cases you could still get
withdraw-then-add behaviors where not strictly necessary. In the case of
bestpath-per-AS this requires one AS to advertise a prefix for the first
time, then a second AS withdraws that prefix, all within the space of an
already pending MRAI timer. In those situations a withdraw-then-add is
more forgivable, and fixing it would probably require a much more
significant effort, as IDs would need to be moved to ADVs instead of
paths.

The subgroup coalesce timer controls how long updates to a particular
subgroup are delayed in order to allow additional peers to join the
subgroup. Presently the timer value is 200 ms. Increase it to 1 second
and adjust up as peers are configured, with an upper cap at 10s.
This cuts convergence time by a factor of 3 at large scale (300+ peers,
1000+ prefixes per peer).

* Move connection initialization to its own thread.c task instead of

* Tons of little fixups
Primary changes are in bgp_packet.[ch], bgp_io.[ch], bgp_fsm.[ch].
Changes made elsewhere are almost exclusively refactoring peer->ibuf to
peer->curr since peer->ibuf is now the true FIFO packet input buffer
while peer->curr represents the packet currently being processed by the

While processing references to the macro PEERAF_FOREACH(), aggressive loop
optimization by gcc 4.9.x (probably 4.8 and greater) was resulting in the
generated code not checking on the index as well as eliminating some code.
This was leading to a dereference of invalid memory when a BGP peer came up.
The fix is to scrap this convoluted macro. Two other changes done are to
eliminate overloading of "afindex" and make the loop iterator an integer.

per draft-ietf-idr-ix-bgp-route-server-09:
2.3.2.2.2. BGP ADD-PATH Approach
The [I-D.ietf-idr-add-paths] Internet draft proposes a different
approach to multiple path propagation, by allowing a BGP speaker to
forward multiple paths for the same prefix on a single BGP session.
As [RFC4271] specifies that a BGP listener must implement an implicit
withdraw when it receives an UPDATE message for a prefix which
already exists in its Adj-RIB-In, this approach requires explicit
support for the feature both on the route server and on its clients.
If the ADD-PATH capability is negotiated bidirectionally between the
route server and a route server client, and the route server client
propagates multiple paths for the same prefix to the route server,
then this could potentially cause the propagation of inactive,
invalid or suboptimal paths to the route server, thereby causing loss
of reachability to other route server clients. For this reason, ADD-
PATH implementations on a route server should enforce send-only mode
with the route server clients, which would result in negotiating
receive-only mode from the client to the route server.
This allows us to delete all of the following code:
- All XXXX_rsclient() functions
- peer->rib
- BGP_TABLE_MAIN and BGP_TABLE_RSCLIENT
- RMAP_IMPORT and RMAP_EXPORT
