Set fq-codel as the default queuing discipline for the shaper traffic-policy if
queue-type has not been configured.
fq-codel has been the default qdisc for OpenWRT as well as systemd (and thus
various linux distributions) for a decent while now. It has proven itself to be
a highly effective qdisc for fighting bufferbloat whilst maintaining high link
utilization. The combination of HTB + fq-codel has also seen wide deployment
in cases when additional traffic classification and/or rate/burst management
is required.
This change will allow the configuration of a shaper traffic-policy with
suitable defaults, saving the pain of having to specify fq-codel as a
queue-type for every class.

I use dummy interfaces in a VRF as source-interfaces for VXLAN in order to force VXLAN send underlay UDP traffic through the VRF where the dummy interface resides.
However dummy interface has no mtu option so it always gets an MTU of 1500. This will cause an error when the mtu of dummy is not large enough for the VXLAN traffic.
Adding this option in the config template will solve this.

Instead of hardcoding the default protocol as TCP in the Python script we shall
use the XML based defaultValue approach instead. This also automatically exports
the default to the CLI completion helper.

move from vfs to overlay driver
The following pre iage upgrade script must be executed to have containers after
the reboot:
for pod in $(cli-shell-api listActiveNodes container name); do
systemctl stop vyos-container-${pod//\'}.service
done
sed -i 's/vfs/overlay/g' /etc/containers/storage.conf /usr/share/vyos/templates/container/storage.conf.j2
rm -rf /usr/lib/live/mount/persistence/container/storage/libpod
for pod in $(cli-shell-api listActiveNodes container name); do
image=$(cli-shell-api returnActiveValue container name ${pod//\'} image)
podman image pull $image
systemctl start vyos-container-${pod//\'}.service
done
for dir in vfs vfs-containers vfs-images vfs-layers; do
rm -rf /usr/lib/live/mount/persistence/container/storage/$dir
done

routing: T1237: Add new feature failover route
|

This add the AdvRASrcAddress configuration option to configure
a source address for the router advertisements. The source
address still must be configured on the system. This is useful
for VRRP setups where you want fe80::1 on the VRRP interface
for cleaner VRRP failovers.

Failover route allows to install static routes to the kernel routing
table only if required target or gateway is alive
When target or gateway doesn't respond for ICMP/ARP checks this route
deleted from the routing table
Routes are marked as protocol 'failover' (rt_protos)
cat /etc/iproute2/rt_protos.d/failover.conf
111 failover
ip route add 203.0.113.1 metric 2 via 192.0.2.1 dev eth0 proto failover
$ sudo ip route show proto failover
203.0.113.1 via 192.0.2.1 dev eth0 metric 1
So we can safely flush such routes

Add interface type veth (Virtual ethernet)
One of the usecases it's interconnect different vrf's and
default vrf via bridge
set interfaces virtual-ethernet veth0 peer-name 'veth1010'
set interfaces virtual-ethernet veth1010 address '10.0.0.10/24'
set interfaces virtual-ethernet veth1010 peer-name 'veth0'
set interfaces virtual-ethernet veth1010 vrf 'foo'
set interfaces bridge br0 address '10.0.0.1/24'
set interfaces bridge br0 member interface veth0

Clients supporting this DHCP option (DHCP option 108, RFC 8925) will
disable its IPv4 network stack for configured number of seconds
and operate in IPv6-only mode.
This option is known to work on iOS 15+ and macOS 12.0.1+.
Example command:
```sh
set service dhcp-server shared-network-name LAN6 subnet 192.168.64.0/24 ipv6-only-preferred 0
```

Instead of spawning the Python interpreter for every mac-address to
validate, rather use the base validate-value OCaml implementation which
is much faster.
This removes redundant code and also makes the CLI more responsive.
Validator is moved out to a dedicated file instead of using XML inlined <regex>
for the reason of re-usability. So if that regex needs to be touched again - it
can all happen in one single file.
|
|
Reduce CPU time when spawning the python interpreter. Same can be done by the
numeric validator.
|
|
Remove duplicated code and move to single-source of truth.
