Commit b7d30137b1 ("vyos.ifconfig: provide generic get_mac_synthetic() method")
provided a common helper to generate MAC addresses used by EUI64 addresses for
interfaces not having a layer2 interface (WireGuard or ip tunnel).
The problem is that every call to the helper always yielded a new MAC address.
This becomes problematic when IPv6 link-local addresses are generated and
modified on the interface as multiple link-local (fe80::/64) addresses can
easily be added to the interface leaving ... a mess.
This commit changes the way how the "synthetic" MAC is generated, we generate a
UUID which is stable as it is based on the interface name. We take out the last
48 bits of the UUID and form the "MAC" address.

When IPv6 is disbaled on an interface also the sysfs files related to IPv6 for
this interface vanish. We need to check if the file exists before we read it.

ipsec: T1441: Clean up vti-up-down script for XFRM interfaces
|
|
|
|
When using VRRP on any given interface and performing an action against that
interface - be it even only changing the alias - will trigger a removal of the
VRRP IP address.
The issue is caused by:
# determine IP addresses which are assigned to the interface and build a
# list of addresses which are no longer in the dict so they can be removed
cur_addr = self.get_addr()
for addr in list_diff(cur_addr, new_addr):
When the script calls into the library - we will drop all IP addresses set on
the adapter but not available in the config dict.
We should only remove the IP addresses marked by the CLI to be deleted!

node is added
Commit f476e456 ("vyos.configdict: leaf_node_changed() must return empty dict
when node is added") returned [''] as "empty" dict - but this is not empty.
>>> if ['']:
... print('foo')
...
foo
It should rather be: []

|
There is no need to alter interface parameters if they have not changed at all.

Commit 2985035b (dhcp-server: T3672: re-add missing "name" CLI option)
unfortunately did not add the name option to the migration script.

The DHCP servers pool {} option can only be used when there follows a range
statement. This is invalid for a network with only "static" leases.
|
|
This option is mandatory and must be user configurable as it needs to match
on both sides.

Restarting DHCPv6 server should not be possible when service is not configured
on the CLI.

DHCP servers "shared-network" level only makes sense if one can specify
configuration items that can be inherited by individual subnets. This is now
possible for name-servers and the domain-name.
set service dhcp-server shared-network-name LAN domain-name 'vyos.net'
set service dhcp-server shared-network-name LAN name-server '192.0.2.1'

IPv4 DHCP uses "dns-server" to specify one or more name-servers for a given
pool. In order to use the same CLI syntax this should be renamed to name-server,
which is already the case for DHCPv6.

vyos@vyos# show service dhcp-server
shared-network-name LAN {
subnet 10.0.0.0/24 {
default-router 10.0.0.1
dns-server 194.145.150.1
lease 88
range 0 {
start 10.0.0.100
stop 10.0.0.200
}
static-route 192.168.10.0/24 {
next-hop 10.0.0.2
}
static-route 192.168.20.0/24 {
router 10.0.0.2
}
}
}

The key defaults to 0 and will match any policies which similarly do not have
a lookup key configuration. This means that a vti0 named interface will pull in
all traffic and others will stop working. Thus we simply shift the key by one
to also support a vti0 interface.
