Current clang has an issue with the pointer/target argument
to at least one atomic/intrinsic. A variable with '_Atomic'
generates a compile-time error. Use a cast as a workaround
here to allow use of clang for now.

When the rib code is informed that a table is closing/
going away, only try once to uninstall associated routes from
the fib/dataplane. The close path can be called multiple times
in some cases - zebra shutdown, e.g.

Both of these are testing/demo-style tools that don't make sense as part

This fixes the longstanding GPL vs. OpenSSL licensing issue in our SNMP
code (and cuts down on its other dependencies a wee bit.)
In a way, net-snmp is really buggy here in what it says that we should
link against, but I don't know their application scenarios well enough
to say it should be changed at their end.

Even if the neighbor entry we want already exists, force its
reinstallation to ensure that it's valid. This will now take place when
we request an update of the neighbor entry.

This command deletes all received routes from the RIP routing table.
It should be used with caution as it can create black holes in the
network until RIP reconverges. Very useful to make automated testing
(e.g. ANVL) more predictable, since the internal state of ripd can be
cleared after each test.
Implement the command using a YANG RPC so that it can be executed by
other northbound clients in addition to the CLI.

Support for fetching operational data is experimental at this point.
Locks must be introduced to ensure the rip->table routing table won't
be modified while we're iterating asynchronously over it (or iterating
from a separate pthread).

The vty configuration lock is used to prevent inconsistencies when
multiple users are editing the configuration at the same time. The
pointer stored in vty->index might become invalid if the associated
configuration object is removed by another user in another CLI session.
Commands converted to the new northbound model don't use vty->index,
but vty->xpath_index and the vty->xpath array. The nb_cli_cfg_change()
function uses the VTY_CHECK_XPATH macro to check if the configuration
object being edited still exists and returns an error if it doesn't.
Now that all ripd commands were converted to the new northbound model,
remove the ripd vty lock because it's not necessary anymore.

We can now leverage the new northbound API to perform a full configuration
reload in ripd without the need for external help (i.e. frr-reload.py).
When vty_read_config() is called with the 'config' parameter set to
NULL, it performs a new configuration transaction where the running
configuration is *replaced* by the provided configuration file. With that
said, we don't need to do anything other than calling this function in
the SIGHUP handler of all FRR daemons. If a daemon hasn't been converted
to the new northbound model, vty_read_config() will simply *merge*
the configuration file into the running configuration.
The calls to rip_clean() and rip_reset() in the SIGUP handler were
changing configuration variables directly, bypassing the northbound
layer. Configuration variables should be changed only by the northbound
callbacks, and failure to respect that inevitably leads to inconsistencies
and crashes. Fix this.

Trivial conversion. Use the northbound 'apply_finish()' callback so
we'll call rip_event() only once even if we change the three RIP timers
at the same time.
Convert the timers to uint32_t to match their representation in the

Trivial conversion. As usual, combine multiple DEFUNs into a single
DEFPY for simplicity.
As a bonus of the northbound conversion, this commit fixes the
redistribution of certain protocols into ripd. The 'redist_type' array
used by the "redistribute" commands was terribly outdated, which was
preventing the CLI to parse correctly certain protocols like isis
and babel.
Remove the route_map hooks installed by rip_route_map_init() since they
were redundant (rip_init() already takes care of that).

In ripd, the "passive-interface default" command has the following
behavior:
* All interfaces are converted to the passive mode;
* The "passive-interface IFNAME" command becomes a no-operation and
"passive-interface IFNAME" statements are removed from the running
configuration.
* The "no passive-interface IFNAME" can be used to remove interfaces
from the passive mode.
This command was modeled using the following YANG data nodes in the
frr-ripd module:
leaf passive-default {
type boolean;
default "false";
description
"Control whether interfaces are in the passive mode
by default or not.";
}
leaf-list passive-interface {
when "../passive-default = 'false'";
type string {
length "1..16";
}
description
"A list of interfaces where the sending of RIP packets
is disabled.";
}
leaf-list non-passive-interface {
when "../passive-default = 'true'";
type string {
length "1..16";
}
description
"A list of interfaces where the sending of RIP packets
is enabled.";
}
The 'when' statements guarantee that the list of passive interfaces
is cleared when the "passive-interface default" command is entered
(likewise, they guarantee that the list of non-passive interfaces is
cleared when the "passive-interface default" command is removed). This
matches exactly the behavior we want to model.
Finally, move the 'passive_default' global variable into the
'rip' structure where it belongs. This fixed the bug where the
"passive-interface default" command was being retained after a "no router
rip" + "router rip".

Remove the rip_offset_list_set() and rip_offset_list_unset() functions
since they set/unset multiple configuration options at the same time. The
northbound callbacks need to set/unset configuration options individually.
The frr-ripd YANG module models the "offset-list" command using a list
keyed by the 'interface' and 'direction' leafs. One important detail is
that the IFNAME parameter is optional, and when it's not present it means
we want to match all interfaces. This is modeled using an interface name
of '*' since key lists are mandatory by definition in YANG.
