Solve issue #4198
Link-ID and Remote IP address must be set accordingly to the interface type
(Point-to-Point or Broadcast) from the neighbor information. However, this
information are only valid once the Network State Machine (NSM) is Full i.e.
when the adjacency is up. The original TE code only look to Interface State
Machine (ISM) change which not allow to collect valid neighbor information.
The patch move setup of Link-ID and Remote-IP TE parameters from
ospf_mpls_te_ism_change() to ospf_mpls_te_nsm_change() function.

Again, the FIFO_* stuff in lib/fifo.h is no different from a simple
unsorted list. Just use DECLARE_LIST here so we can get rid of FIFO_*.

Historically, isisd has been carrying around its own red-black tree to
manage its LSP DB in. This replaces that with the newly-added
DECLARE_RBTREE_*. This allows completely removing the dict_* code.

Since all of these list implementations provide almost the same API, we
can run and validate them against the same test code. 9 tests for the

These two are lock-free linked list implementations, the plain one is
primarily intended for queues while the sorted one is for general data

Typesafe red-black tree, built out of the OpenBSD implementation and the
macro soup layered on top. API compatible with skiplists & simple
lists.
Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
By the power of the C preprocessor, these macros provide type-safe
warppers for simple lists, skiplists and hash tables. Also, by changing
the instantiation macro, it is easily possible to switch between
algorithms; the code itself does not need to be changed since the API
is identical across all algorithms.

The upcoming gRPC-based northbound plugin will run on a separate
pthread, and it will need to have access to the running configuration
global variable. Introduce a rw-lock to control concurrent access
to the running configuration. Add the lock inside the "nb_config"
structure so that it can be used to protect candidate configurations
as well (this might be necessary depending on the threading scheme
of future northbound plugins).

The ability to lock the running configuration to prevent other users
from changing it is a very important one. We already supported
the "configure exclusive" command but the lock was applied to
the CLI users only (other clients like ConfD could still commit
configuration transactions, ignoring the CLI lock). This commit
introduces a global lock for the running configuration that is
shared by all northbound clients, and provides a public API to
manipulate it. This way other northbound clients will also be able
to lock/unlock the running configuration if required (the upcoming
gRPC northbound plugin will have RPCs for that).
NOTE: this is a management-level lock for the running configuration,
not to be confused with low-level locks used to avoid data races.

Problem reported that route-maps applied to "ip protocol table bgp"
would not be invoked if the ip protocol table command was issued
after the bgp prefixes were installed. Found that a recent change
improving how often nexthop_active_update runs missed causing this
filtering to be applied. This fix resolves that issue as well as
a couple of other places that were problematic with the recent
change.

Problem reported that if a bgp neighbor had a bfd timer change
made in frr.conf and systemctl reload frr performed, the neighbor
with the timer changed bounced. If the change is made in vtysh
by just adding the new timer values, no peer bounce occurs. This
fix skips the delete part of the delete/add process in frr-reload
so the peers stay up.

in the case the vrf backend is vrf-lite, there is no need to have
separate sockets. use a socket located in zrouter, so that when needing
the socket, a common API is used. that API will return the appropriate
socket value.

The alias/description of an interface in linux was being
used to override the internal description. As such let's
fix the display to keep track of both if we have it.
Config in FRR:
!
interface docker0
description another combination
!
interface enp3s0
description BAMBOOZLE ME WILL YOU
!
Config in linux:
sharpd@robot ~/f/zebra> ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
