Netjsonconfig

--------------------------

Features
~~~~~~~~

- Added support for the new `DSA bridge syntax to the OpenWrt backend
<http://netjsonconfig.openwisp.org/en/latest/backends/openwrt.html#openwrt-backend>`_
- Added support for `Wireguard
<http://netjsonconfig.openwisp.org/en/latest/backends/wireguard.html>`_
and `Wireguard/VXLAN
<http://netjsonconfig.openwisp.org/en/latest/backends/vxlan_over_wireguard.html>`_
- Added support for `Wireguard interfaces in OpenWrt backend
<http://netjsonconfig.openwisp.org/en/latest/backends/openwrt.html#wireguard>`_
- Added support for `VXLAN interfaces in OpenWrt backend
<http://netjsonconfig.openwisp.org/en/latest/backends/openwrt.html#vxlan>`_
- Added ``auth_nocache`` proprety to the ``OpenVpn`` backend
- Added support for OpenVPN tls-auth option, the OpenVPN backend will
automatically create a file for the key present in "tls_auth" field and
update the value of the "tls-auth" parameter
- Added ``proto`` to remote setting of the ``OpenVpn`` backend
- Added support for IEEE 802.11w configurations to the ``OpenWrt`` backend
- Added support for Wifi6 / IEEE 802.11ax to the ``OpenWrt`` backend
- Added support for basic IEEE 802.11r options to the ``OpenWrt`` backend
- Added support for WPA3 to the ``OpenWrt`` backend
- Added support for EAP-PEAP as ``auth`` method in WPA2 enterprise wifi
client configuration of ``OpenWrt`` backend
- Removed option of 2.4GHz radio for 802.11ac from the ``OpenWrt`` backend

Changes
~~~~~~~

Backward incompatible changes
+++++++++++++++++++++++++++++

- By default, the ``OpenWrt`` backend now generates bridge syntax in the
new DSA compatible format, to override this, ``dsa=False`` must be
passed during the initialization of the backend

Dependencies
++++++++++++

- Dropped support for Python 3.6
- Added support for Python 3.8 and 3.9
- Upgraded Jinja to 3.0
- Upgraded jsonschema to 3.2.x
- Upgraded to openwisp-utils 1.0.x and reformatted code with latest
version of the black formatter

Other changes
+++++++++++++

- Simplified bridging of wifi interfaces in the OpenWrt backend: users can
now simply add a wifi interface to a bridge and forget about having to
update also the attached networks of the OpenWrt configuration

Bugfixes
~~~~~~~~

- Ensured values are always deep copied when using ``merge_config``,
without this change the different schemas remain interwined and a
dynamic change to one part which is reused by other schemas will affect
different backends inadvertently
- The file ``path`` is not allowed to be an empty string anymore
- Ignored duplicate list elements when merging templates: detect identical
elements present in both lists to avoid adding the duplicate to the
result; this is needed because some templates may share one or multiple
common files and these do not not have to be duplicated
- Fixed typo in EAP TTLS protocol ``enum_title`` of ``OpenWrt`` backend:
it was showing EAP-PEAP even though TTLS was set
- Fixed madwifi driver for legacy systems
- Fixed comp-lzo option for legacy OpenVPN in OpenWisp1 backend
- Fixed UCI format backward compatibility with OpenWISP 1 This fix is
needed to allow workarounds in the code of OpenWISP-Firmware to keep
working also with OpenWISP 2

--------------------------

- [fix] Removed ``mtu_disc`` from ``auto_client`` method because it causes
issues on most OpenWRT systems
- [fix] Avoided maxLength on PIN property to allow configuration variables
- [change] Add missing TLS ciphers to OpenVPN

--------------------------

- [change] **Potentially backward incompatible**: added support for dialup
interfaces (ppp, pppoe, pppoa, 3g, qmi, ncm, wwan, pptp, 6in4, aiccu or
l2tp) to openwrt backend. This change is backward incompatible if the
same type of configuration was achieved using a workaround, in these
cases the configuration will have to be upgraded to use the new format.
- [feature] Added support for modem manager interfaces

--------------------------

- [fix] Fixed bug in OpenWRT backend validation for ip_rules/src

--------------------------

- Fixed bug that prevented overriding the contents of a file present in a
template and caused the file to be duplicated instead of overwritten
- Fixed bug affecting backward conversion of switch VLAN on OpenWRT

--------------------------

- Changed default file mode for certificate files generated with from
``0644`` to ``0600``
