Nixpkgs: network-manager-applet does not prompt for wifi passphrase when selecting a new network

[obadz]

Issue description

networkmanagerapplet (a.k.a. nm-applet) does not prompt for wifi passphrase when selecting a new network.

The problem can be circumvented by with services.gnome3.gnome-keyring.enable = true; or by using nmtui instead of nm-applet.

This started happening with 8dc518c2dfb58e986d5ea2ddc5a630862725276f which removed the dependency of nm-applet on gnome3.libgnome-keyring (among other things).

@jtojnar made two good points:

1. nm-applet can used other keyrings (https://github.com/NixOS/nixpkgs/commit/8dc518c2dfb58e986d5ea2ddc5a630862725276f#r28366386)
2. the fact that nm-applet silently fails when no keyring is available is an upstream bug (https://github.com/NixOS/nixpkgs/commit/8dc518c2dfb58e986d5ea2ddc5a630862725276f#r28369001)

I commented on the upstream bug: https://bugzilla.gnome.org/show_bug.cgi?id=750290#c3 but that bug has been open for 3 years now, so not holding my breath.

From the user's perspective, this is a pretty big regression: Consider the case of a user using the XFCE desktop manager, or nm-applet with i3. When upgrading from 17.09 to 18.03, this user will no longer be able to punch in wifi passphrases when s/he join new networks.

Unless someone has a better idea, I'd suggest adding back the dependency of on gnome3.libgnome-keyring in networkmanagerapplet (and/or any other dependency that's required to fix this issue).

Cc @jtojnar (and @volth / @yegortimoshenko who seem to be doing lots of XFCE work)

Steps to reproduce

1. Install NixOS 18.03 or unstable with XFCE desktop manager.
2. Attempt to join a new Wifi network secured by a PSK
3. The popup window prompting for the key never appears

[volth]

is it related to gnome-keyring?
I see WiFi passwords are saved in plain-text in /etc/NetworkManager/system-connections/

And the dialog does prompt for WiFi password (it does not for VPN, but that is another bug related to insufficient privileges):

[volth]

Ah, sorry.
I'm using master from 2018-03-20, a bit before merging https://github.com/NixOS/nixpkgs/pull/36893 which caused the regression

[jtojnar]

Do you have a configuration.nix to reproduce this in QEMU? Perhaps with mac80211_hwsim.

[obadz]

Ok, here comes the repro (on 48d4cef9d31):

{ config, pkgs, ... }:

{
  boot.kernelModules = [ "mac80211_hwsim" ];

  networking.networkmanager.enable = true;
  services.xserver.enable = true;
  services.xserver.libinput.enable = true;
  services.xserver.displayManager.lightdm.enable = true;
  services.xserver.desktopManager.xfce.enable = true;
  # services.gnome3.gnome-keyring.enable = true;

  users.extraUsers.guest = {
    isNormalUser = true;
    uid = 1000;
    initialPassword = "";
    extraGroups = ["users" "wheel" "networkmanager"];
  };
}

Then the usual:

nix-build -E '(with import <nixpkgs/nixos> { configuration = import ./configuration.nix; }; vm)' &&
    rm -vf nixos.qcow2 &&
    ./result/bin/run-nixos-vm

And finally inside the VM:

nmcli dev wifi hotspot ifname wlan1 ssid Test\ Wifi password testitnow123

(I wasn't able to get hostapd to work)

From there, you'll see the network appear in the menu but won't be able to connect. Will work fine with nmtui.

Uncomment the services.gnome3.gnome-keyring.enable line in the config and the password prompt now works fine.

[jtojnar]

Cool. When I kill nm-applet and then run it in a terminal, I can see the following output:

** Message: 07:33:19.892 Remote error from secret service: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.secrets was not provided by any .service files

The message seems to come from libsecret itself.

[obadz]

@jtojnar, so this confirms your theory but how do we fix this in a way that's user friendly?

[jtojnar]

A note in release notes is friendly enough for me.

Other than that, if upstream is unable to reproduce it, we could try to find the offending codepath ourselves.

I tried running gdb --pid=$(pidof nm-applet) with

  environment.enableDebugInfo = true;

It trapped correctly after creating the hotspot and typing continue. backtrace produced the following:

Unfortunately, it is not very helpful due to all the threads and services. Not sure how to debug it better.

[obadz]

Other than that, if upstream is unable to reproduce it, we could try to find the offending codepath ourselves.

Very nice effort on the debugging. I learned a few tricks reading that comment, so thanks.

A note in release notes is friendly enough for me.

I must say I wholeheartedly disagree. I understand that NixOS targets power-users but finding yourself with a host that you can't get on the network after install/upgrade without any obvious error messages is one of the most frustrating experience we could give to our users.

I've confirmed that the following fixes the issue:

I'd argue that unless we can find a better solution, adding this dependency is better than keeping the silent failure. Upstream has been unresponsive for years but if they ever wake up it's easy enough for us to revert the workaround.

Other than Gnome Keyring, what other backends to libsecrets are there? I could only find KWallet and greping into nixpkgs suggests that KDE doesn't even use networkmanagerapplet, at least unless a user explicitly installs it.

[jtojnar]

I think Qt based desktop managers would use KWallet.

I agree, that adding it with a FIXME comment with link here should be good enough for now, though.

It would be nice to be able to set break point to nma_wifi_dialog_new.

Apparently, you can just use break nma_wifi_dialog_new and it will find the correct function. After removing the libsecret patch, I verified that the function never gets called – at least the breakpoint does not seem to get triggered.
