Bug 1647783

Created attachment 1503299 [details]
fc29 (not working) logs from /var/log/messages

Description of problem:
NetworkManager doesn't complete the connection to a "WPA & WPA2 Enterprise" (in particular I'm connecting to an eduroam access point: eduroam.org). This doesn't happen with WPA & WPA2 Personal WiFi connections.

Looking at the NM cli monitor I see:

    # systemctl restart NetworkManager; nmcli monitor
    
    wlo1: disconnected
    wlo1: connecting (prepare)
    wlo1: using connection 'eduroam'
    Networkmanager is now in the 'connecting' state
    wlo1: connecting (configuring)
    wlo1: connecting (need authentication)
    wlo1: connecting (prepare)
    wlo1: connecting (configuring)
    wlo1: connecting (getting IP configuration)
    wlo1: connection failed
    Networkmanager is now in the 'disconnected' state

and this is repeated over and over.

This happens also with the newer NetworkManager packages in the updates repo (see below).


Installing the NetworkManager RPM packages for fc28 didn't solve:

    # dnf install --releasever=28 --arch=x86_64 nm-connection-editor network-manager-applet NetworkManager{,{-glib,-libnm,-team,-adsl,-libnm,-wifi,-bluetooth,-ppp,-wwan}}
    
    # systemctl restart NetworkManager; nmcli monitor
    ...
    wlo1: connecting (getting IP configuration)
    wlo1: connection failed
    Networkmanager is now in the 'disconnected' state


Instead, if I download and install packages for fc27, the *same* connection setup (using the same parameters I set in the network-manager-applet in my traybar) works perfectly (unfortunately the repo structure is different in fc27 so dnf is unable to download packages):

    # wget -Nc https://dl.fedoraproject.org/pub/fedora/linux/releases/27/Everything/x86_64/os/Packages/n/{{nm-connection-editor,network-manager-applet}-1.8.4-1.fc27.x86_64.rpm,NetworkManager{,{-glib,-libnm,-team,-adsl,-libnm,-wifi,-bluetooth,-ppp,-wwan}}-1.8.4-2.fc27.x86_64.rpm}
    # dnf install *fc27*
    # systemctl restart NetworkManager; nmcli monitor

    wlo1: disconnected
    wlo1: connecting (prepare)
    wlo1: using connection 'eduroam'
    Networkmanager is now in the 'connecting' state
    wlo1: connecting (need authentication)
    wlo1: connecting (prepare)
    wlo1: connecting (configuring)
    eduroam: connection profile changed
    eduroam: connection profile changed
    wlo1: connecting (getting IP configuration)
    wlo1: connecting (checking IP connectivity)
    wlo1: connecting (starting secondary connections)
    wlo1: connected
    'eduroam' is now the primary connection
    Networkmanager is now in the 'connected (site only)' state
    eduroam: connection profile changed
    Connectivity is now 'full'
    Networkmanager is now in the 'connected' state



While the connection is being loaded with fc28-fc29 packages, `ifconfig wlo1` reports:

    wlo1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
            inet6 fe80::a1d5:dcb9:b98c:4f28  prefixlen 64  scopeid 0x20<link>

Version-Release number of selected component (if applicable):

The following packages are impacted (not reporting all the other packages: NetworkManager{,{-libnm,-team,-adsl,-libnm,-wifi,-bluetooth,-ppp,-wwan}} ):

NetworkManager-1.12.4-2.fc29.x86_64.rpm (from fc29 updates repo)
NetworkManager-1.12.4-1.fc29.x86_64.rpm (from fc29 base repo)
NetworkManager-1.10.12-2.fc28.x86_64.rpm (from fc28)


Steps to Reproduce:
1. Setup a "WPA & WPA2 Enterprise" connection, e.g. using the network manager applet in the XFCE traybar. In particular I'm trying to use an eduroam connection inside my university (so there are multiple access points around my laptop) and I don't have access to the access point.
2. Connect to the network you just setup.

Actual results:
The connection fails after a minute it tries to connect, apparently in the phase of obtaining the IP.


Expected results:
Connect to the WiFi network.
