VyOS CLI command
set service ndp-proxy interface eth0 prefix 2001:db8::/64 mode 'static'
Will generate the following NDP proxy configuration
$ cat /run/ndppd/ndppd.conf
# autogenerated by service_ndp-proxy.py
# This tells 'ndppd' how often to reload the route file /proc/net/ipv6_route
route-ttl 30000
# This sets up a listener, that will listen for any Neighbor Solicitation
# messages, and respond to them according to a set of rules
proxy eth0 {
# Turn on or off the router flag for Neighbor Advertisements
router no
# Control how long to wait for a Neighbor Advertisment message before invalidating the entry (milliseconds)
timeout 500
# Control how long a valid or invalid entry remains in the cache (milliseconds)
ttl 30000
# This is a rule that the target address is to match against. If no netmask
# is provided, /128 is assumed. You may have several rule sections, and the
# addresses may or may not overlap.
rule 2001:db8::/64 {
static
}

Since `service dns dynamic address <address> service <service> ...`
changed to `service dns dynamic name <service> address <address> ...`,
the resulting service and address config flip can result in conflicting
`service` name.
Additionally, since dynamic DNS service name now have name constraint,
we need to normalize the service name to conform with the constraint.
We now migrate the service name to (service|rfc2136)-<service>-<address>
to avoid the conflict and optionally append an index if there is still a
name conflict after normalization.

|
When migrating from `service dns dynamic interface <interface> ...` to
`service dns dynamic address <address> ...`, the config name can
potentially have a conflict when `address == 'web'`.
Although the `/run/ddclient/ddclient.conf` that was generated earlier
was incorrect, one could still potentially have misconfigured VyOS
config without realizing it.
We now append the old <interface> name to the config name to avoid
conflict.

migration: T5413: re-sequence interfaces migration scripts
|
|
PR https://github.com/vyos/vyos-1x/pull/2540 backported a migration script from
current to the equuleus LTS branch. As migration scripts are executed in order
to adjust the CLI for necessary improvements in future LTS releases we need to
change the versioning of the migration files to match the new "base" version
from the previous LTS release.
In theory this could break very ancient 1.4 rolling releases (from the early
days of the OSPF refactoring) - but those versions are considered very much
unstable.
Now this is the last chance to sync up the migration scripts before the 1.4 LTS
release.

accel-ppp: T5688: Standardized pool configuration in accel-ppp
|
|
Standardized pool configuration for all accel-ppp services.
1. Only named pools are used now.
2. Allows all services to use range in x.x.x.x/mask
and x.x.x.x-x.x.x.y format
3. next-pool can be used in all services
2. Allows to use in ipoe gw-ip-address without pool configuration
which allows to use Fraimed-IP-Address attribute by radius.
3. Default pool name should be explicidly configured
with default-pool.
4. In ipoe netmask and range subnet can be different.

Found an odd behavior on Linux and the VyOS CLI implementation. If adding VXLAN
interfaces using iproute2 the MTU differs depending on the creation syntax:
ip -4 link add vxlan100 type vxlan dstport 4789 external df unset tos inherit \
ttl 16 nolearning vnifilter local 172.16.33.201
ip -4 link add vxlan200 type vxlan id 200 dstport 4789 local 172.16.33.201 dev eth0
ip -6 link add vxlan300 type vxlan id 300 dstport 4789 local 2001:db8:1::1 dev eth0
132: vxlan300: <BROADCAST,MULTICAST> mtu 1430 qdisc noop state DOWN group default qlen 1000
link/ether 4e:fb:e3:f5:d9:59 brd ff:ff:ff:ff:ff:ff
133: vxlan200: <BROADCAST,MULTICAST> mtu 1450 qdisc noop state DOWN group default qlen 1000
link/ether 0e:4e:f4:76:59:3f brd ff:ff:ff:ff:ff:ff
134: vxlan100: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether ba:b6:b7:0c:b1:37 brd ff:ff:ff:ff:ff:ff
VyOS always sets a default MTU of 1450 bytes which is correct for IPv4 p2p links
or multicast, but invalid for IPv6 p2p. Also this will break EVPN deployments
as ethernet bridges with MTU < 1500 bytes are less fun.
Increase default MTU to 1500 bytes. Migrate old configurations to use 1450
bytes if not specified otherwise on the CLI.

This complements commit f5e43b136 ("http: T5762: api: make API socket backend
communication the one and only default") so we have a consistent port CLI node
across VyOS components.
|
|
Why: Smoketests fail as they can not establish IPv6 connection to uvicorn
backend server.
https://github.com/vyos/vyos-1x/pull/2481 added a bunch of new smoketests.
While debugging those failing, it was uncovered, that uvicorn only listens on
IPv4 connections
vyos@vyos# netstat -tulnp | grep 8080
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN -
As the CLI already has an option to move the API communication from an IP to a
UNIX domain socket, the best idea is to make this the default way of
communication, as we never directly talk to the API server but rather use the
NGINX reverse proxy.

pim(6): T5733: add missing FRR related features
|
|
|
|
IGMP and PIM are two different but related things.
FRR has both combined in pimd. As we use get_config_dict() and FRR reload it
is better to have both centrally stored under the same CLI node (as FRR does,
too) to just "fire and forget" the commit to the daemon.
"set protocols igmp interface eth1" -> "set protocols pim interface eth1 igmp"

<enable|disable> commands; log and state moved to new syntax.

Fix execution bit for migration script
|
|
- Migrate to ddclient 3.11.1 and enforce debian/control dependency
- Add dual stack support for additional protocols
- Restrict usage of `porkbun` protocol, VyOS configuration structure
isn't compatible with porkbun yet
- Improve and cleanup error messages
|
|
`web-options` is only applicable when using HTTP(S) web request to
obtain the IP address. Apply guard for that.
|
|
Time interval in seconds to wait between DNS updates would be a bit
more intuitive as `interval` than `timeout`.
|
|
As we have a bunch of options under "paramteres" already and "external" is
clearly one of them it should be migrated under that node as well.

vxlan: T5671: change port to IANA assigned default port
|
|
Currently VyOS VXLAN implementation uses the Linux assigned port 8472 that
predates the IANA assignment. As Most other vendors use the IANA assigned port,
follow this guideline and use the new default port 4789.
Existing configuration not defining an explicit port number will be migrated
to the old default port number of 8472, keeping existing configurations work!

bonding: T5254: Fixed changing ethernet when it is a bond member
|
|
|
|
interface-name|interface-group as in firewall.
|
|
If ethernet interface is a bond memeber:
1. Allow for changing only specific parameters which are specified
in EthernetIf.get_bond_member_allowed_options function.
2. Added inheritable parameters from bond interface to ethernet
interface which are scpecified
in BondIf.get_inherit_bond_options.
Users can change inheritable options under ethernet interface
but in commit it will be copied from bond interface.
3. All other parameters are denied for changing.
Added migration script. It deletes all denied parameters under
ethernet interface if it is a bond member.

Q-in-Q interface
When migration from 1.3 to 1.4 and a user hat the following configured:
options {
interface eth0.10{
adjust-mss 1452
adjust-mss6 1432
}
}
The configuration was wrongly migrated to:
interfaces {
ethernet eth0.10 {
ipv6 {
adjust-mss "1432"
}
ip {
adjust-mss "1452"
}
}
Instead of
interfaces {
ethernet eth0 {
vif 10 {
ipv6 {
adjust-mss "1432"
}
ip {
adjust-mss "1452"
}
}
}
