[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
So, is anyone going to fix this? It is in LTS now and causing havoc. Fwiw, I support that it should allow split resolution just like it used to do. This change was a major breaking one that shouldn't have been forced on people.

[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
I hope something can be worked out before this lands in the next LTS- release. This breaks one of the most common uses of a VPN (remote work). Right now a workaround is using this script after connecting to a VPN- server: https://github.com/jonathanio/update-systemd-resolved It calls systemd-resolved via DBus to add the proper settings after the OpenVPN connection is established. Of course this means abandoning NetworkManager for use with OpenVPN, because there is also no way to specify --up and --down parameters. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1726124 Title: DNS domain search paths not updated when VPN started Status in network-manager package in Ubuntu: Confirmed Status in network-manager-openvpn package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: I connect to work with openvpn through network-manager-openvpn.

[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
I'm not sure why it's being asserted that these two uses are mutually incompatible, especially since I've been using them in a coordinated way forever and can still do so (at the expense of junking systemd-resolve and going back to using dnsmasq and a custom configuration, which is obviously a big pain). I've even, in the past, used MULTIPLE VPNs, even at the same time, and it still just works. If the resolver library (e.g., gethostbyname etc.) gets an unqualified hostname, it uses the search path just as it always has including ndots and all that stuff, to generate FQ hostnames. No change there. When the local resolver caching service (dnsmasq, systemd-resolv) gets a FQ hostname it looks through the extensions provided by the VPN DHCP information and if the hostname matches that extension it forwards the lookup to the DNS server for that VPN. If it doesn't match, it doesn't forward the request. If it doesn't match any of the VPN search paths, it forwards the request to the default DNS servers. I honestly don't understand why we're considering these uses incompatible. They seem to me to be exactly compatible and exactly what you want to do, at least the vast majority of the time. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1726124 Title: DNS domain search paths not updated when VPN started Status in network-manager package in Ubuntu: Confirmed Status in network-manager-openvpn package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: I connect to work with openvpn through network-manager-openvpn.

[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
This change in behavior is deliberate. There are two mutually incompatible interpretations of DNS search lists provided via a VPN connection. One is for split DNS, to say "this is the list of domains for which you should send lookups to the accompanying DNS server". The other is to use it as a search list for resolv.conf. Unfortunately, interpreting wrongly in either direction breaks client configs. But whereas there are other ways that one can configure the behavior of resolv.conf to add search domains, the only reasonable way to configure split DNS is to do so by providing this information directly from network-manager-openvpn to systemd-resolved. It may be that network-manager-openvpn needs an additional configuration option, to allow the user to declare which of these two ways (or both, or neither) they want to use the VPN server-provided DNS search list. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1726124 Title: DNS domain search paths not updated when VPN started Status in network-manager package in Ubuntu: New Status in network-manager-openvpn package in Ubuntu: New Status in systemd package in Ubuntu: New Bug description: I connect to work with openvpn through network-manager-openvpn.

[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
To be clear, they are NOT updated in /etc/resolv.conf. They ARE updated in /run/NetworkManager/resolv.conf, but that has no effect since we're not using that for resolution: instead we're using systemd-resolve. And as I noted above, it does appear that systemd-resolve is notified about the search domains, because "systemd-resolve --status" does show them associated with the openvpn tun0 device. However, those search domains are never manifested in the /run/systemd/resolve/stub-resolv.conf which is what /etc/resolv.conf is pointing to, so they never take effect. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1726124 Title: DNS domain search paths not updated when VPN started Status in network-manager package in Ubuntu: New Status in network-manager-openvpn package in Ubuntu: New Status in systemd package in Ubuntu: New Bug description: I connect to work with openvpn through network-manager-openvpn.

[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
Right, so it seems like NM checks the never-default setting, and doesn't push them as resolve domains =/ I will test things out to be sure. Specifically: $ nmcli c show YOUR_VNP_CONNECTION_NAME | grep never-default ipv4.never-default: yes ipv6.never-default: yes And if it is never-default, it doesn't push search domains out, only routing domains. I believe this might be actually correctly intended configuration of the openvpn and network-manager and resolved. Since all traffic is not routed to the VPN connection, its domain names should not be used for resolution. E.g. resolving "foo.company.example.net" should work and should end up being resolved via nameserver on the vpn, and not leak DNS resolution to public DNS server, and one should be able to connect to that host. But resovling "foo" should be failing. I understand this is a change of behaviour, thus does seem like a regression. I will consult on what is correct behaviour and how to best fix it. ** Tags added: regression-release -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1726124 Title: DNS domain search paths not updated when VPN started Status in network-manager package in Ubuntu: New Status in network-manager-openvpn package in Ubuntu: New Status in systemd package in Ubuntu: New Bug description: I connect to work with openvpn through network-manager-openvpn.

[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
I'm not sure I understand what you mean. In a typical configuration you never send "foo" to the nameservice, there's always a search domain and those lookups are always tried first (because the default value for the ndots is 1). This is handled by the libc resolver linked into every program, it's not handled by a central service. I don't have any idea how systemd-resolve works. But, my understanding of how it used to work with dnsmasq using split tunneling was that the nameservice mapped domains to DNS servers, and the resolver would only forward requests to the DNS server that matched the domain for the host being requested. If you have a VPN interface that adds "mycorp.com" to the search domain that appears in /etc/resolv.conf search, so it contains "mycorp.com localdomain" for example. Then when someone tries to resolve "myhost", the libc resolver sees that there are no dots here and so it starts appending search paths to the hostname, in order, and sending them to the DNS service to look up. So first it will send "myhost.mycorp.com" to the resolver. The resolver sees that the hostname ends in "mycorp.com" and it knows that the VPN DNS servers "own" that domain, so it forwards that request to those servers for lookup. If that doesn't match, then the libc resolver will try to look up "myhost.localdomain". That does NOT match the VPN domain, so it will not try to forward that to the DNS servers for the VPN connection and instead use a different resolver. I don't think there's any information leakage here. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1726124 Title: DNS domain search paths not updated when VPN started Status in network-manager package in Ubuntu: New Status in network-manager-openvpn package in Ubuntu: New Status in systemd package in Ubuntu: New Bug description: I connect to work with openvpn through network-manager-openvpn.

[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
Paul Smith, what you describe is information leakage and shouldn't IMHO work as you say by default. Consider that I'm connected to a corporate network and have an (untrusted) VPN active which I only want to use to access resources on its network (never-default: yes). Then by having the resolver adding the domain of the VPN network to short name lookups could leak those local names to the remote VPN (depending on the order the lookups are performed in) and potentially allow the untrusted network to take over internal services that are accessed using short names. This could happen by mistake also (such as setting "mail" as your smtp server if the remote network uses the same name). I don't think the order of the lookups can be controlled to prevent this, for example what should determine the order when you have to VPN active? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1726124 Title: DNS domain search paths not updated when VPN started Status in network-manager package in Ubuntu: New Status in network-manager-openvpn package in Ubuntu: New Status in systemd package in Ubuntu: New Bug description: I connect to work with openvpn through network-manager-openvpn.

[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
Andreas: unfortunately disallowing short name lookups is not acceptable: many environments use short names in embedded URLs all over the place, and without domain search paths the entire environment is rendered completely unusable (e.g., URLs are simply https://tools/foo or https://wiki/foo or whatever; this means no cross-links work). Connecting to an untrusted VPN is a tiny sliver of a minority of the usage of VPN; 99.99% of the time when someone connects to a VPN they're trying to create a secure link to another trusted network (e.g., working remotely). If you want to provide support for both modes of handling short names with some kind of checkbox to select between them that's fine with me, but the current behavior is a serious loss of functionality from previous solutions. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1726124 Title: DNS domain search paths not updated when VPN started Status in network-manager package in Ubuntu: New Status in network-manager-openvpn package in Ubuntu: New Status in systemd package in Ubuntu: New Bug description: I connect to work with openvpn through network-manager-openvpn.

[Touch-packages] [Bug 1726124] Re: DNS domain search paths not updated when VPN started
My guess is that rls-bb-notfixing means this is not getting fixed in Bionic Beaver 18.04. Really hoping a fix can make it into the 20.04 LTS release though. I agree with Paul - systemd-resolve is not doing what it promises to do. >From systemd.network(5): Both "search" and "routing-only" domains are used for routing of DNS queries: look-ups for host names ending in those domains (hence also single label names, if any "search domains" are listed), are routed to the DNS servers configured for this interface. The domain routing logic is particularly useful on multi-homed hosts with DNS servers serving particular private DNS zones on each interface. The "routing-only" domain "~." (the tilde indicating definition of a routing domain, the dot referring to the DNS root domain which is the implied suffix of all valid DNS names) has special effect. It causes all DNS traffic which does not match another configured domain routing entry to be routed to DNS servers specified for this interface. This setting is useful to prefer a certain set of DNS servers if a link on which they are connected is available. This setting is read by systemd-resolved.service(8). "Search domains" correspond to the domain and search entries in resolv.conf(5). Domain name routing has no equivalent in the traditional glibc API, which has no concept of domain name servers limited to a specific link. One partial workaround is to remove `[!UNAVAIL=return]` after `resolve` in /etc/nsswitch.conf: hosts: files mdns4_minimal [NOTFOUND=return] resolve dns myhostname That way a traditional DNS resolution is done after systemd-resolve fails. This works for everything I've tested so far _except_ Google Chrome. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1726124 Title: DNS domain search paths not updated when VPN started Status in network-manager package in Ubuntu: Confirmed Status in network-manager-openvpn package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: I connect to work with openvpn through network-manager-openvpn. I'm selecting automatic (DHCP) to get an IP address, and "Use this connection only for resources on its network" to support split tunneling. In the last few versions of Ubuntu I used, this all worked fine. In Ubuntu 17.10 (fresh install, not upgrade) I can access hosts on both my VPN network and the internet, BUT I have to use FQDN for my VPN network hosts: the updates to the DNS search path provided by my VPN DHCP server are never being applied. Investigating the system I see that /etc/resolv.conf is pointing to /run/systemd/resolve/stub-resolv.conf and that resolv.conf does not have any of the VPN's search path settings in it: # This file is managed by man:systemd-resolved(8). Do not edit. # # 127.0.0.53 is the systemd-resolved stub resolver. # run "systemd-resolve --status" to see details about the actual nameservers. nameserver 127.0.0.53 search home In previous versions of Ubuntu, where NetworkManager controlled the resolver not systemd, /etc/resolv.conf pointed to /run/NetworkManager/resolv.conf and there was a local dnsmasq instance that managed all the complexity. In Ubuntu 17.10 when I look in /run/NetworkManager/resolv.conf file, I see that the search paths ARE properly updated there: $ cat /run/NetworkManager/resolv.conf # Generated by NetworkManager search internal.mycorp.com other.mycorp.com home nameserver 127.0.1.1 However this file isn't being used, and also there's no dnsmasq running on the system so if I switch my /etc/resolv.conf to point to this file instead, then all lookups fail.
