The Solaris code has gone through a deprecation cycle. No-one
has said anything to us and worse of all we don't have any test
systems running Solaris to know if we are making changes that
are breaking on Solaris. Remove it from the system so
we can clean up a bit.

Code was added in the past to support a value of VRF_DEFAULT different
from 0. This option was abandoned, the default vrf id is always 0.
Remove this code, this will simplify the code and improve performance
(use a constant value instead of a function that performs tests).

vrf_id_to_name() looks up in a RB_TREE to find the VRF entry, then
reads the name.
Avoid it for VRF_DEFAULT, which always exists and for which the
translation is straightforward.

The vrf_get function is called throughout the code base
so much so that when you turn on vrf debugging it eclipses
everything else to a degree that is completely unreasonable.

In the new Sysrepo, all SR_EV_ENABLED notifications are followed by
SR_EV_DONE notifications (assuming no errors occur), so there's no
need to special case the SR_EV_ENABLED event anymore (e.g. do full
transactions in one step).
While here, add a few more guarded debug messages to facilitate
troubleshooting.

Make the sysrepo plugin ignore the deletion of configuration
nodes that don't exist anymore instead of logging an error and
rejecting the changes. This is necessary because Sysrepo delivers
delete notifications for all nodes of a deleted data tree instead
of delivering a single delete notification of the top-level subtree
node (which would suffice for the northbound layer).

From Sysrepo's documentation:
"Note: do not use fork() after creating a connection. Sysrepo
internally stores PID of every created connection and this way a
mismatch of PID and connection is created".
Introduce a new "frr_very_late_init" hook in libfrr that is only
called after the daemon is forked (when the '-d' option is used)
and after the configuration is read. This way we can initialize
the sysrepo plugin correctly even when the daemon is daemonized,
and after the Sysrepo CLI commands are processed (only "debug
northbound client sysrepo" for now).

When installing rules pass by the interface name across
zapi.
This is being changed because we have a situation where
if you quickly create/destroy ephermeal interfaces under
linux the upper level protocol may be trying to add
a rule for a interface that does not quite exist
at the moment. Since ip rules actually want the
interface name ( to handle just this sort of situation )
convert over to passing the interface name and storing
it and using it in zebra.

Change the way the YANG schema node iteration functions work so that
the northbound layer won't have issues with more complex YANG modules
that contain multiple levels of YANG augmentations or modules that
augment themselves indirectly (by augmenting groupings).
Summary of the changes:
* Change the yang_snodes_iterate_subtree() function to always follow
augmentations and add an optional "module" parameter to narrow down
the iteration to nodes of a single module (which is necessary in
some cases). Also, remove the YANG_ITER_ALLOW_AUGMENTATIONS flag
as it's no longer necessary.
* Change yang_snodes_iterate_all() to do a DFS iteration on the resolved
YANG data hierarchy instead of iterating over each module and their
augmentations sequentially.

Whenever libyang loads a module that contains a leafref, it will
also implicitly load the module of the referring node if it's
not loaded already. That makes sense as otherwise it wouldn't be
possible to validate the leafref value correctly.
The problem is that loading a module implicitly violates the
assumption of the northbound layer that all loaded modules
are implemented (i.e. they have a northbound node associated
to each schema node). This means that loading a module that
isn't implemented can lead to crashes as the "priv" pointer
of schema nodes is no longer guaranteed to be valid. To fix this
problem, add a few null checks to ignore data nodes associated
to non-implemented modules.
The side effect of this change is harmless. If a daemon receives
configuration it doesn't support (e.g. BFD peers on staticd),
that configuration will be stored but otherwise ignored. This can
only happen when using a northbound client like gRPC, as the CLI
will never send to a daemon a command it doesn't support. This
minor problem should go away in the long run as FRR migrates to
a centralized management model, at which point the YANG-modeled
configuration of all daemons will be maintained in a single place.
Finally, update some daemons to stop implementing YANG modules
they don't need to (i.e. revert 1b741a01c and a74b47f5).

Signed-off-by: David Schweizer <dschweizer@opensourcerouting.org>
The "set metric" command wasn't processing metric additions and
subtractions (using + and -) correctly. Fix those problems.
Also, remove the "+metric" and "-metric" options since they don't
work and don't make any sense (they could be interpreted as unitary
increments/decrements but that was never supported).

If we have an interface configured in a daemon on shutdown
store the old ifindex value for retrieval on when it is
possibly recreated.
This is especially important for nexthop groups as that we
had at one point in time the ability to restore the
configuration but it was lost when we started deleting
all deleted interfaces. We need the nexthop group subsystem
to also mark that it has configured an interface.
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
The nexthop_group_write_nexthop_simple function outputs the
interface name, because we've stored the ifindex. The problem
is that there are ephermeal interfaces in linux that can be
destroyed/recreated. Allow us to keep that data and do something
a bit smarter to allow show run's and other show commands to continue
to work when the interface is deleted.

Wildcards bits have the opposite representation of a network mask,

representation is 0.0.255.255.
