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.

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,

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.

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.

Make rip_neighbor_add() and rip_neighbor_delete() return northbound
error codes since their return values are used as the return value of
some northbound callbacks.
These functions shouldn't fail in normal conditions because the northbound
layer guarantees it will never call the 'create' or 'delete' callback
more than once for the same object. Hence any failure in those functions
would indicate an internal inconsistency that needs to be investigated
(by returning NB_ERR the northbound will log a detailed error message
indicating the xpath of the object, the event and the callback where
the error happened).

The "distance (1-255) A.B.C.D/M [WORD]" command was modeled using a

The rip_distance_set() and rip_distance_unset() functions were removed
since they set/unset multiple configuration options at the same time. The

a pointer in the configuration node, and retrieve this pointer in the
other callbacks using yang_dnode_get_entry().

Programs that link to libnetsnmp must be compiled using a special set
of flags as specified by the "net-snmp-config --base-cflags" command
(whose output is stored in the SNMP_CFLAGS variable). The problem is
that "net-snmp-config --base-cflags" can output -std=c99 in addition to
other compiler flags in some platforms, and this breaks the build since
FRR souce code makes use of some GNU compiler extensions (e.g. allow
trailing commas in function parameter lists). In order to solve this
problem, append -std=gnu99 after SNMP_CFLAGS in all makefiles where this
variable is used. This way the -std=c99 flag will be overwritten when it's
present. Source files that don't link to libnetsnmp will be compiled using
either -std=gnu99 or -std=gnu11 depending on the compiler availability.

This option is only implemented by 4 daemons:
- BGPD
- RIPD
- RIPNGD
- Zebra
Manpages and documentation say that the option causes routes to not be
uninstalled from zebra when the daemon terminates. This is true for RIPD
and RIPNGD. This is not true for BGPD; in that daemon it only prevents
transmission of Cease / Peer Unconfig NOTIFICATION messages to peers.
Moreover, when any daemon disconnects from Zebra, all of its routes are
uninstalled from Zebra and the kernel regardless of this option,
rendering the option largely vestigial.
It is still useful in Zebra, where it prevents all routes from being
uninstalled when Zebra shuts down, so it is left there.

The code was attempting to access a variable that would always be NULL.
In fact this code has been broken since the rip ECMP changes
were put into place a few years back.
I'm going to come straight out and say that I don't fully
understand this code. rinfo is the first item in the ecmp
list and tmp_rinfo is used to iterate over all the items
in the ecmp list. It sure looks like that the changes
made here were just hacked together. So I modified
the tmp_rinfo loop to just work on tmp_rinfo and
the check that was crashing I modified to just use
the rinfo since that what was checked originally
in code before the ECMP was added. So consider
this a hack job to stop the crashing.
I think worse case is that we might be sending some routes
back out interfaces it shouldn't be if you have
ip rip split-horizon poisoned-reverse configured but
that is less bad(tm) than crashing.

This is a fallout from PR #1022 (zapi consolidation). In the early days,
the client daemons would allocate enough memory to send all nexthops

MULTIPATH_NUM only when installing the routes in the kernel. Now things
are different and the client daemons can send at most MULTIPATH_NUM
nexthops to zebra, and failure to respect that will result in a buffer

performance implications and will allow us to remove an ugly exception
we had for ldpd (which needs to know all nexthops of the redistributed

The way thread.c is written, a caller who wishes to be able to cancel a
thread or avoid scheduling it twice must keep a reference to the thread.
Typically this is done with a long lived pointer whose value is checked
for null in order to know if the thread is currently scheduled. The
check-and-schedule idiom is so common that several wrapper macros in
thread.h existed solely to provide it.
This patch removes those macros and adds a new parameter to all
thread_add_* functions which is a pointer to the struct thread * to
store the result of a scheduling call. If the value passed is non-null,
the thread will only be scheduled if the value is null. This helps with
consistency.
A Coccinelle spatch has been used to transform code of the form:
if (t == NULL)
t = thread_add_* (...)
to the form
thread_add_* (..., &t)
The THREAD_ON macros have also been transformed to the underlying
