We have "set system name-server <ipv4|ipv6>" to specify a name-server IP
address we wan't to use. We also have "set system name-servers-dhcp <interface>"
which does the same, but the name-server in question is retrieved via DHCP.
Both CLI nodes are combined under "set system name-server <ipv4|ipv6|interface>"
to keep things as they are in real life - we need a name-server.

T3697: fix the deadlock in IPsec options script
|
|
The root cause is that the ipsec-settings.py script is run _twice_:
first from "vpn ipsec options", then from the top level "vpn" node.
The case when it's not required is when:
* "vpn ipsec" configuration doesn't exist yet
* user configured it with "vpn ipsec options"
* the ipsec-settings.py script is run first time, from "vpn ipsec options"
Trying to restart charon at that stage leads to a deadlock.

Commit 27e53fbc ("op-mode: T3619: bugfix "show interfaces" for VLANs") fixed
the op-mode command for the "show interfaces" operation, but if a user was
interested in all the ethernet or bridge interfaces, the command "show
interfaces <type> detail" did not yield any output.
The filtered_interfaces() function was further generalized to only operate on
base components and call itself recusively if required.

Commit 31169fa8a7 ("vyos.ifconfig: T3619: only set offloading options if
supported by NIC") always instantiated an object of the Ethtool class for an
ethernet object - this is right as a real ethernet interface is managed by
Ethtool.
Unfortunately the script used for "show interface" determindes the "base class"
for an interface by its name, so eth0 -> Ethernet, eth0.10 -> Ethernet. This
assumption is incorrect as a VLAN interface can not have the physical parameters
changed of its underlaying interface. This can only be done for eth0.
There is no need for the op-mode script to determine the implementation class
for an interface at this level, as we are only interested in the state of the
interface and it's IP addresses - which is a common operation valid for every
interface on VyOS.

Keys are not allowed with ipip and sit tunnels

Several scripts imported by vyos-configd (including
src/conf_mode/protocols_static.py) rely on argv for operating on VRFs.
Always setting script.argv in src/services/vyos-configd ensures those
scripts will operate on the default VRF when called with no arguments.
Otherwise, a stale argv might cause those scripts to operate on the last
modified VRF instead of the default VRF.

nipsec: T3093: Delete temporarily generated code
|
|
This code was generated before to rewrite IPSec to XML style
And this was rewriten/fixed and used in the next 1.4 releases
So we realy don't need it in 1.3 as we use old nodes for it.

While migrating to get_config_dict() in commit e8a1c291b1 ("login: radius:
T3192: migrate to get_config_dict()") the user-name was not excluded
from mangling (no_tag_node_value_mangle=True).
This resulted in a username "vyos-user" from CLI to be actually created as
"vyos_user" on the system.
This commit also adds respective Smoketests to prevent this in the future.

sstp-server: T2661: Delete CA certificate redundancy check
|
|
Commit 9f20bee81c ("T1376: improve show_dhcp and show_dhcpv6") added the tab
completion helper to list the availbale IP pools to query. This was done by
calling a python script which then called cli-shell-api which resulted in a
penalty by the Python interpreter startup.
This can be solved by directly using the cli-shell-api wrapper available
as <path> in op-mode - as also seen for DHCPv6.

It makes no sense to have a parser for the ethtool values in ethtool.py
and ethernet.py - one instance ios more then enough!

Only update the RX/TX ring-buffer settings if they are different from the ones
currently programmed to the hardware. There is no need to write the same value
to the hardware again - this could cause traffic disruption on some NICs.

Not all interface drivers have the ability to change the speed and duplex
settings. Known drivers with this limitation are vmxnet3, virtio_net and
xen_netfront. If this driver is detected, an error will be presented to the
user.

Ethernet adapters have a discrete set of available speed and duplex settings.
Instead of passing every value down to ethtool and let it decide, we can do
this early in the VyOS verify() function for ethernet interfaces.

SSH keys used for remote login are supplied as base64 encoded data on the CLI.
The key is not validated, thus an invalid copy/pasted key will render the login
useless. This commit adds a custom and re-usable validator which check if the
data is properly base64 encoded.

Deprecated in the Linux Kernel by commit 08a00fea6de277df12ccfadc21 ("net:
Remove references to NETIF_F_UFO from ethtool.").

An analysis of the code base from VyOS 1.2 -> 1.3 -> 1.4 revealed the following
"root-cause"
VyOS 1.2 uses the "old" node.def file format for:
* Generic Segmentation Offloading
* Generic Receive Offloading
So if any of the above settings is available on the configuration CLI, the
node.def file will be executed - this is how it works.
By default, this CLI option is not enabled in VyOS 1.2 - but the Linux Kernel
enables offloading "under the hood" by default for GRO, GSO... which will boost
the performance for users magically.
With the rewrite in VyOS 1.3 of all the interface related code T1579, and
especially T1637 this was moved to a new approach. There is now only one handler
script which is called whenever a user changes something under the interfaces
ethernet tree. The Full CLI configuration is assembled by get_interface_dict() -
a wrapper for get_config_dict() which abstracts and works for all of our
interface types - single source design.
The problem now comes into play when the gathered configuration is actually
written to the hardware, as there is no GSO, GRO or foo-offloading setting
defined - we behave as instructed and disable the offloading.
So the real bug originates from VyOS 1.2 and the old Vyatta codebase, but the
recent XML Python rewrites brought that one up to light.
Solution:
A configuration migration script will be provided starting with VyOS 1.3 which
will read in the CLI configuration of the ethernet interfaces and if not
enabled, will query the adapter if offloading is supported at all, and if so,
will enable the CLI nodes.
One might say that this will "blow" the CLI configuration but it only represents
the truth - which was masked in VyOS 1.2.

FRR: op-mode: T3776: rename "restart frr <daemon>" to "restart <daemon>"
|
|
As IS-IS is a new feature and the CLI configuration changed from 1.3 -> 1.4
(required by T3417) it makes sense to synchronize the CLI configuration for
both versions. This means backporting the CLI from 1.4 -> 1.3 to not confuse
the userbase already with a brand new feature.
As 1.3.0-epa1 is on the way and should not contain any CLI changes afterwards,
this is the perfect time.

Re-issuing the same iproute2 commands can lead to errors, simply ignore

It is easier to backport the entire vyos.ifconfig library from 1.4 instead of
backporting single pieces which are required to add new feature to the tunnel
interface section.
In addition that both libraries are now back in sync it will become much easier
to backport any other new feature introduced in VyOS 1.4!
