Merge ~danilogondolfo/netplan/+git/ubuntu:mantic_0_107_1_sru into ~ubuntu-core-dev/netplan/+git/ubuntu:ubuntu-mantic

* rm .pyc/__pycache__ in python3-netplan.preinst? => Do we want/need this in Noble, too? (Can you create a Salsa MR against debian/unstable?)
* d/control: We might want to keep the openvswitch-switch <!nocheck> build-depends on armhf, as it's still built on Mantic
=> This would allow getting rid of debian/patches/0002-ovs-disable-StartLimitBurst-in-the-ovs-cleanup-servi.patch, too. IMO
=> non-blocking: As the OVS autopkgtests are skipped on armhf, too, due to missing kernel module in the container
* note (non-blocking): The 0.107.1-3ubuntu0.23.10.1 version string is (currently) bigger than what we have in noble-release, but this will be resolved by 1.0-1 in noble-proposed (stuck due to armhf time_t)
=> We should probably keep this version string as-is

LGTM! I'm just slightly concerned about the first bullet point and a little bit about the 2nd (for not reducing OVS test coverage on armhf)

review: Approve

[Lukas Märdian (slyon)]

We discussed the .preinst situation out-of-band and agreed that python3-netplan does not own any files in /usr/share/netplan, so should not touch those and the script should stay within the netplan.io binary.

Builds are looking good in https://launchpad.net/~danilogondolfo/+archive/ubuntu/netplan-sru/+packages

[Danilo Egea Gondolfo (danilogondolfo)]

I also submitted the netplan.io.preinst script to Debian https://salsa.debian.org/debian/netplan.io/-/merge_requests/12

+
+When the prefix is omitted for IPs in the allowed-ips list, we were
+appending a /32 to them without checking the address family.
+
+IPv6 addresses will have a /128 appended to them if it's not present.

-Subject: parse: improve the parsing of access-points (LP: #1809994)
-
-When the parser requires a second pass, it will report access-points it
-already parsed as duplicates and error out.
-
-With this change, access-points will be stored in a local hash table,
-which will be used to find duplicates in the same netdef, and moved to
-the netdef->access_points hash table in the end. Access-points already
-present in the netdef hash table will be considered already parsed and
-skipped.
-
-Add a test to check the problem is fixed and another one to test if
-merging the access-points when the same interface is present in multiple
-files is working properly.

-If we find an AP with the same name in the same interface, we drop the
-first one and use the new one. This is done to maintain the documented
-behavior of respecting the order in which the files are parsed. We still
-need to implement support for merging AP settings.

-Subject: wireguard: ignore empty endpoints
-
-The Network Manager GUI will emit 'Endpoint=' if it's not specified when
-creating the tunnel. libnetplan is generating 'endpoint: ""' in this case
-and the parser is returning an error.
-
-In nm-parse, if Endpoint is either empty or NULL we'll just not read it. In
-the parser, if we find 'endpoint: ""', we'll just ignore it as if it
-were not defined.
-
-See LP: #2038811

-Subject: auth: add support for LEAP and EAP-PWD
-
-This changes add support for the LEAP and PWD EAP authentication methods
-for NetworkManager, wpa_supplicant (networkd) and the keyfile parser.
-
-Using these method through the NM GUI is causing problems because
-libnetplan will generate a broken keyfile. See LP: #2038811
-
-Note that the NM GUI supports more methods not recognized by netplan and
-we probably should also implement them later.

 ## How it works
 
 Every time a non-temporary connection is created in NetworkManager, instead
-of persisting the original .nmconnection file, it will create a Netplan YAML
-at `/etc/netplan` called `90-NM-<connection UUID>.yaml`. After creating the
-file, NetworkManager will call the Netplan generator to emit the configuration
-for that connection.	Connections that are temporary, like the ones created
-for virtual network interfaces when you connect to a VPN for example, are not
-persisted as Netplan files. The reason for that is that these interfaces are
-usually managed by external services and we don't want to cause any unexpected
-change that would affect them.

+unexpected change that would affect them.
 
-## How to install it
+## How to use
 
-### Creating a backup of your current configuration
-
-The new NetworkManager will remove connection profiles that you eventually
-modify from `/etc/NetworkManager`. So you might want to create a copy of all
-your connection profiles before installing the new network-manager package:
+### Installing NetworkManager
 
+The NetworkManager 1.44.2 package containing the Netplan integration patch
+is available by default in Ubuntu 23.10 "Mantic Minotaur" and later as part of
+the official Ubuntu archive.
 ```
-$ mkdir ~/NetworkManager.bak && cd ~/NetworkManager.bak/
-$ sudo cp -r /etc/NetworkManager/system-connections .
+$ sudo apt update
+$ sudo apt install network-manager
 ```
 
-In any case, a backup will be created automatically for you at
-`/root/NetworkManager.bak` during package installation.
-
-And also keep a copy of all the original network-manager related packages in
-case you want to revert to the previous installation:
+### User interface
 
-```
-$ apt download gir1.2-nm-1.0 libnm0 network-manager network-manager-config-connectivity-ubuntu
-```
+From this point on, Netplan is aware of all your network configuration and
+you can query it using its CLI tools, such as `sudo netplan get` or `sudo
+netplan status`. All while keeping untouched the traditional way of modifying
+it using NetworkManager (graphical UI, GNOME Quick Settings, `nmcli`,
+`nmtui`, D-Bus APIs, ...).
 
-### Installing NetworkManager
+### Management of connection profiles
 
-The NetworkManager 1.42.0 package containing the Netplan integration patch
-is currently available as a PPA. In order to install it, you will need to
-have `netplan.io >= 0.106` installed in your system (it is available in Lunar).
+The NetworkManager-Netplan integration imports connection profiles from
+`/etc/NetworkManager/system-connections/` to Netplan during the installation
+process. It automatically creates a copy of all your connection profiles during
+the installation of the new network-manager package in
+`/root/NetworkManager.bak/system-connections/`. The same migration happens
+in the background whenever you add or modify any connection profile.
 
+You can observe this migration on the `apt-get`` command line. Watch for
+logs like the following:
 ```
-$ sudo add-apt-repository ppa:canonical-foundations/networkmanager-netplan
-$ sudo apt update
-$ sudo apt install network-manager

-## How connections are managed from now on
-
-After installing the new NetworkManager, your existing connection profiles
-will not be imported to Netplan YAML files, only new connections and the
-existing ones you eventually modify.
-
-For example, if you have a Wifi connection, you will find the connection
-profile file at `/etc/NetworkManager/system-connections`. If you modify it
-using one of the NetworkManager's interfaces (or delete and create a new one),
-the respective file will be removed from `/etc/NetworkManager/system-connections`,
-a Netplan YAML called `90-NM-<connection UUID>.yaml` will be created at
-`/etc/netplan` and a new profile will be generated and stored at
-`/run/NetworkManager/system-connections`.
+For example, if you have a Wifi connection, you will not find the connection
+profile file at `/etc/NetworkManager/system-connections/` anymore. Instead,
+the system removes the profile file, and Netplan creates a new YAML file called
+`90-NM-<connection UUID>.yaml` in `/etc/netplan/` and generates a new ephemeral
+profile in `/run/NetworkManager/system-connections/`.
