[Desktop-packages] [Bug 1998207] Re: netplan network-manager plugin tries to save temporary connections
I think this should probably fix the duplicated temporary connections
issue. Netplan should only ever try to handle non-temporary connections,
nothing that's being written to NMS_KEYFILE_STORAGE_TYPE_RUN (like those
external OpenVPN connections). More testing is needed to investigate the
side-effects of this change.

When creating an OpenVPN connection, a temporal connection called tunN
is created. For instance, after activating a connection called

should not really be saved, but I see netplan adding it in
/etc/netplan. And while doing so the plugin also reports some errors

[Desktop-packages] [Bug 1998207] Re: netplan network-manager plugin tries to save temporary connections
After taking another look at this I noticed that the function where we create the Netplan YAML is called when the connection is created AND when the connection is going down as though it was being updated. The first time it's called the parameters is_volatile, is_nm_generated and is_external are all set to true so we skip the libnetplan calls. Although when it's called when the connection is going down they are all false. And that's when the Netplan file is created and network-manager gets to a point in the code it shouldn't reach, so it crashes and the files are never removed. Not sure if calling the plugin writer in this case is a bug or not as the connection is volatile and is going to be deleted anyway. Maybe lost tracking of the connection nature (volatile, nm_generated and external) is the actual bug, not sure yet. One way to work around this is generating Netplan YAMLs regardless if the connection is volatile. If network-manager will create a file for it we could create a file for Netplan too. In fact, after removing the conditions to call libnetplan, the files are created and deleted when the OpenVPN client and/or server is stopped. Note that from network-manager 1.42.0 on, even the loopback interface can be represented as a connection, so we will have a Netplan file for it as well. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1998207 Title: netplan network-manager plugin tries to save temporary connections Status in netplan: Triaged Status in network-manager package in Ubuntu: Triaged Bug description: *** Note: This bug is mostly about comment #10, now *** When creating an OpenVPN connection, a temporal connection called tunN is created.

Thanks! I've added the "!is_external" check to my latest development patch revision at: https://github.com/slyon/NetworkManager/commits/netplan-nm-1.40 So this bug report is now mostly about comment #10, where the openvpn client/plugin is creating a temporary tunX device, which is displayed as "external" in "nmcli d", but still a Netplan YAML file is created in /etc/netplan on "nmcli con down ". I can easily reproduce this issue locally, using Canonical VPN and see tunX connection definitions piling up in /etc/netplan/ when bringing it up&down a few times in a row.

"nmcli c" should show a tunX connection and the VPN connection. "nmcli d" should show tunX as a external connection. 4. Disconnect the VPN connection (nmcli c down ) 5.

[Desktop-packages] [Bug 1998207] Re: netplan network-manager plugin tries to save temporary connections
> So IIUC the connection works as expected, but only after reloading the connection profiles; it doesn't show up at the time it is expected, right? Hm, not sure if we mean the same. That two connections (tun2 and ) appear after connecting to the VPN is expected. NM recognizes tun2 as "external" as it is an auxiliary device/connection created by the OpenVPN plugin. The problem that is happening is that that connection is being stored in /etc/netplan/, which should not be the case. Note that tun0 and tun1 are slightly different as those are created by the OpenVPN server also running on the device. The netplan files for them are not written anymore after changing the patch. > Does running 'nmcli connection reload' after the connection profile for the VPN connection (tun2?) got written, make it show up in the NM daemon? No, that does not happen. But it happens if I reboot the system. I think that is because there is some file in /run that prevents this from happening if just reloading things.

Note that when you create an OpenVPN connection both a normal NM
connection and a new tunnel device (tun2) are created. NM creates a
external device for tun2. The interesting thing here is that the file
for tun2 is written after setting down the connection, and the NM daemon
actually forgets it (until you restart it and reads the netplan file).
Maybe this storing is in a different code path.

[Desktop-packages] [Bug 1998207] Re: netplan network-manager plugin tries to save temporary connections
Hmm.. OK. So I assume those connections would normally (not using the netplan integration) be created in /run/NetworkManager/system- connections/...? So I think we need to find a way to detect NMS_KEYFILE_STORAGE_TYPE_RUN, or respectively ignore any connections that are not of NMS_KEYFILE_STORAGE_TYPE_ETC, but that data is not directly available in the nms-keyfile-writer.c code.

[Desktop-packages] [Bug 1998207] Re: netplan network-manager plugin tries to save temporary connections
ACK. IIRC there's a "nm-generated" flag inside the NM connection profile, which we could check to avoid calling into the libnetplan integration if exists. So this actually affects NetworkManager's libnetplan integration patch more than Netplan itself, IMO: https://github.com/slyon/NetworkManager/tree/slyon/backend-1.36.6 ** Changed in: netplan Status: New => Triaged ** Changed in: netplan Importance: Undecided => Medium ** Changed in: netplan Importance: Medium => High ** Also affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1998207 Title: netplan network-manager plugin tries to save temporary connections Status in netplan: Triaged Status in network-manager package in Ubuntu: New Bug description: When creating an OpenVPN connection, a temporal connection called tunN is created. For instance, after activating a connection called vpntest, I have: NAME UUID TYPE DEVICE vpntest 458856e6-8f0f-4dc6-82f2-dd72868252a0 vpn ens3 tun0 1eb1dbe8-5678-4818-9adf-fb2dc01ed132 tun tun0 tun0 is created/removed after activating/deactivating vpntest and should not really be saved, but I see netplan adding it in /etc/netplan. And while doing so the plugin also reports some errors (I see these when stopping the connection): Nov 28 16:16:57 ubuntu NetworkManager[11752]: [1669652217.2920] BUG: the profile cannot be stored in keyfile format without becoming unusable: cannot access file: No such file or directory Nov 28 16:16:57 ubuntu NetworkManager[11752]: ((src/libnm-core-impl/nm-connection.c:342)): assertion '' failed Nov 28 16:16:57 ubuntu NetworkManager[11752]: [1669652217.2920] keyfile: commit: failure to write 1eb1dbe8-5678-4818-9adf-fb2dc01ed132 ((null)) to "/run/NetworkManager/system-connections/tun0-1eb1dbe8-5678-4818-9adf-fb2dc01ed132.nmconnection": keyfile writer produces an invalid connection: cannot access file: No such file or directory To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/1998207/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
