Add support for prefix delegation when receiving the prefix via ethernet,
bridge, bond, wireless.
|
|
This is to remove the amount of duplicated entries in dictionaries. It's one
more part to move to a unified interface management.

The following configuration will assign a /64 prefix out of a /56 delegation
to eth0. The IPv6 address assigned to eth0 will be <prefix>::ffff/64.
If you do not know the prefix size delegated to you, start with sla-len 0.
pppoe pppoe0 {
authentication {
password vyos
user vyos
}
description sadfas
dhcpv6-options {
delegate eth0 {
interface-id 65535
sla-id 0
sla-len 8
}
}
ipv6 {
address {
autoconf
}
enable
}
source-interface eth1
}
vyos@vyos:~$ show interfaces
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
Interface IP Address S/L Description
--------- ---------- --- -----------
eth0 2001:db8:8003:400::ffff/64 u/u

PowerDNS recursor 4.3 now uns as user pdns and group pdns, thus the
generated configuration file and directory need to have the appropriate
permissions set.

- define XML CLI interface
- read CLI into Python dict

CLI commands used for ruleset generation:
set nat source rule 100 outbound-interface 'eth0.202'
set nat source rule 100 protocol 'all'
set nat source rule 100 source address '192.0.2.0/26'
set nat source rule 100 translation address 'masquerade'
set nat source rule 110 outbound-interface 'eth0.202'
set nat source rule 110 protocol 'tcp'
set nat source rule 110 source address '192.0.2.0/26'
set nat source rule 110 source port '5556'
set nat source rule 110 translation address 'masquerade'

The generated NAT rules in VyOS 1.2 are compared to the generated nftables
ruleset in VyOS 1.3 this was done by converting the 1.2 iptables ruleset to
nftables and then do the diff. To convert from iptables to nftables use the
following command:
$ iptables-save -t nat > /tmp/tmp.iptables
$ iptables-restore-translate -f /tmp/tmp.iptables
The following CLI options have been used for testing:
set nat destination rule 10 description 'foo-10'
set nat destination rule 10 destination address '1.1.1.1'
set nat destination rule 10 destination port '1111'
set nat destination rule 10 exclude
set nat destination rule 10 inbound-interface 'eth0.202'
set nat destination rule 10 log
set nat destination rule 10 protocol 'tcp_udp'
set nat destination rule 10 translation address '192.0.2.10'
set nat destination rule 15 description 'foo-10'
set nat destination rule 15 destination address '1.1.1.1'
set nat destination rule 15 exclude
set nat destination rule 15 inbound-interface 'eth0.202'
set nat destination rule 15 log
set nat destination rule 15 protocol 'tcp_udp'
set nat destination rule 15 translation address '192.0.2.10'
set nat destination rule 20 description 'foo-20'
set nat destination rule 20 destination address '2.2.2.2'
set nat destination rule 20 inbound-interface 'eth0.201'
set nat destination rule 20 log
set nat destination rule 20 protocol 'tcp'
set nat destination rule 20 translation address '192.0.2.10'

Destination NAT configuration: destination ports can only be specified when
protocol is tcp, udp or tcp_udp.

When instantiating NAT it is required to isntall some nftable jump targets.
The targets need to be added after a specific other target thus we need to
dynamically query the handler number. This is done by get_handler() which could
be moved to vyos.util at a later point in time so it can be reused for a
firewall rewrite.

Commit 9e5c6a935e2f55 ("tunnel: T2449: set accept_ra=2 if ipv6 address autoconf
or dhcpv6 is set") referenced wrong key in dict.

To make SLAAC and DHCPv6 work when forwarding=1, accept_ra must be 2
(default for accept_ra is 1).

wireless: T2427: migrate to use common configdict and vlan functions, add common interface includes to template

Other interfaces were previously migrated, but this one was forgotten,
causing a commit error:

We've already verified that all member interfaces don't have any
addresses configured, so it should be safe to simply call 'ip addr flush' on
them to flush the remaining addresses (e.g. IPv6 link-local)

- make error output more user friendly
- replace .format with f-strings
- split into lines less than ~80 characters long
|
|
Previously, the interface was always deleted and recreated, which
removed it from the bridge.
- always re-add the interface back to any bridge it is part of
