Fix `peer_default_originate_unset` so default route can be withdrawn
when `default-originate` option is being unset from a peer-group.
The loop calling `bgp_default_originate` is clearing default-originate
from the peer-group peer `peer` instead of the peer-group member peer
`member`.

This test checks the interactions between the BGP label requesting
code and the labelpool code to ensure the correct number of labels
and label chunks are requested and those labels are freed back into
the pool when the corresponding prefix is removed.
Signed-off-by: Pat Ruddy <pat@voltanet.io>
The check for the return code for zclient_send_get_label_chunk is
reversed and therefore the pending count does not get incremented
for each successful label chunk request.
This has the effect of requesting a 50 label chunk per label request
from BGP i.e we request 50 times the labels we require.

To prepare for fixing an issue where labels do not get released back
to the labelpool when the route is deleted some refactoring is
necessary. There are 2 parts to this.
1. restructure the code to remove the circular nature of label
allocations via the labelpool and decouple the label type decision
from the notification fo the FEC.
The code to notify the FEC association to zebra has been split out
into a separate function so that it can be called from the synchronous
path (for registration of index-based labels and de-registration of all
labels), and from the asynchronous path where we need to wait for a
callback from the labelpool code with a label allocation.
The decision about whether we are using an index-based label or an
allocated label is reflected in the state of the BGP_NODE_LABEL_REQUESTED
flag so the checks on the path_info in the labelpool callback code are
no longer required.
2. change the owned of a labelpool allocated label from the path info
structure to the bgp_dest structure. This allows labels to be released
(in a subsequent commit) when the owner (bgp_dest) goes away.

When dplane_fpm_nl is used the "Please add this protocol(n) to proper
rt_netlink.c handling" debug message is emitted for any route of type
kernel or connected.
This severely reduces performance of dplane_fpm_nl when large numbers
of these routes are present in the RIB.
The messages are not observed when using the original fpm module since
this uses a custom function, netlink_proto_from_route_type().
zebra2proto() now returns RTPROT_KERNEL for ZEBRA_ROUTE_CONNECT and
ZEBRA_ROUTE_KERNEL. This should only impact dplane_fpm_nl's use of
the common netlink routines since these routes generally ignored via
checking of RSYSTEM_ROUTE().

fpm_nl_process() now ensures that the dataplane thread is rescheduled
if it hits the work limit while processing its incoming work queue.
This would probably already occur due to some other event, such as
fpm_process_queue() enqueuing completed work to the output queue,
however it does no harm to add this explicit reschedule.
Signed-off-by: Duncan Eastoe <duncan.eastoe@att.com>
If the dataplane thread hits the work limit while processing the
output queue for any given provider, we now explicitly reschedule
the thread.
Otherwise, if the number of items in the output queue is greater than
the work limit, draining of that output queue is dependent on new
dataplane work.
Routes which are not drained from the output queue are stuck with
the 'q' flag, so this is a similar issue to that observed in
164d8e8608.

If a local-MAC or local-neigh is not active locally it is not sent to BGP.
At this point if BGP rxes a remote route it accepts it and installs in
zebra. Zebra was rejecting BGP's update if it had a higher seq local (inactive)
entry. This would result in bgp and zebra falling out of sync.
In some cases zebra would delete the local-inactive entries in sometime (as
a part of the dplane/kernel garbage collection). This would leave zebra
with missing remote entries (which were still present in bgpd).
This change allows lower-seq BGP updates to overwrite zebra's local entry if
that entry happens to be local-inactive.
Note: This logic was already in use for sync-mac-ip updates. Extended the
same logic to remote-mac-ip updates.

If a netlink/dp notification is rxed for a neigh without the peer-sync
flag FRR re-installs the entry with the right flags. This change is

the VxLAN).

If a remote MAC update is rxed from BGP with a lower sequence number than
the local one zebra ignores the MAC update. This typically happens if
there is a race condition (where updates are in flight from zebra to BGP).
There was a bug in zebra because of which the dest ES was being updated
before this check. This left the local MAC pointing to a remote ES.

With EVPN-MH, Type-2 routes are also used for MAC-IP syncing between
ES peers so a change was done to only treat REACHABLE local neigh
entries as local-active and advertise them as Type-2 routes i.e. STALE
neigh entries are no longer advertised as Type-2s.
This however exposed some unexpected problems with MLAG where a
secondary reboot followed by a primary reboot left a lot of neighs
in STALE state (on the primary) resulting in them not being
advertised. And remote routed traffic to those hosts being
blackholed in a sym-IRB setup.
This commit is a workaround to fix the regression (it doesn't fix
the underlying problems with entries not becoming REACHABLE; which
maybe a day-1 problem). The workaround is to continue advertising
STALE neighbors if EVPN-MH is not enabled.
