NMCLI issue with creating a wifi bridge-slave #7389

Closed blackbicbiro closed 7 months ago

blackbicbiro commented 11 months ago

Summary

Attempting to create a wifi hotspot as part of a bridge. This is possible using the NMCLI. When attempting to do it using the NMCLI module the slave_type always defaults back to Bond.

Configuration


      - name: Create a Bridge Interface connection
        community.general.nmcli:
          type: bridge
          conn_name: br0
          method4: auto
          # ip4: "{{ ip_address }}"
          stp: false
          autoconnect: true
          state: present

      - name: Add Wifi connection profile for Bridge interface br0
        community.general.nmcli:
          type: wifi
          conn_name: br0-hotspot
          slave_type: bridge
          master: br0
          ssid: HotSpot
          wifi:
            mode: ap
          wifi_sec:
            key-mgmt: wpa-psk
            psk: "{{ vault_wifi_psk }}"
          method4: link-local
          autoconnect: false
          state: present

not setting the slave_type to bridge. It sets it to bond

OS / Environment

Host: Pop_OS! 22:04 Target: Ubuntu 22.04.4 server

Steps to Reproduce

Bridge setup with DHCP 1 x Ethernet at bridge slave 1 x wifi adaptor setup as bridge slave

Run playbook and check the settings for the connection profile

nmcli connection show br0-hotspot

Output shows the slave-type as bond not bridge as defined with the play book

Running the playbook with verbose -vvv shows the following config so it should be setting the slave-type to bridge

Implemented the same config using CLI and NMCLI works every time.

-$ sudo nmcli connection add con-name "br0-hotspot" type wifi slave-type bridge master br0 wifi.mode ap wifi.ssid HotSpot wifi-sec.key-mgmt wpa-psk wifi-sec.psk "password-wifi" autoconnect no

Seems like the slave-type is being ignored and default to bond for wifi. It also seems to set a interface-name which is not required. nmcli will use the first available interface if not defined. it seems to set the interface name as the same as the connection name

Looking at the module file i assume its something do do with this on lines 1819. looks like it uses the default of bond. Regardless of defining it as bridge nmcli does allow you to define wifi interfaces as part of a bridge

        elif self.type == 'wifi':
            options.update({
                '802-11-wireless.ssid': self.ssid,
                'connection.slave-type': 'bond' if self.master else None,
gianmarco-mameli commented 9 months ago

Hi, found the same behavior in Raspberry PI OS Bookworm arm64, the wifi has connection.slave-type: bond instead of bridge, thanks
