From the IRC discussion: 23:01 RAOF stgraber: I don't suppose there's a way to get the best of both worlds? Have dnsmasq ignore the interfaces you need, *and* pick up new interfaces? 23:01 RAOF For example: how disruptive is restarting dnsmasq? Please note that Simon Kelley is working on enhancing dnsmasq so that it will automatically detect new interfaces and addresses (on LInux, anyway). That's much better than restarting dnsmasq. Once that enhancement is available, forcing dnsmasq into bind-interfaces mode will be less disruptive. Forcing dnsmasq into bind-interfaces mode now is disruptive, but not terribly so; stgraber argues (persuasively, IMHO) that libvirt and lxc should force standalone dnsmasq into bind-interfaces mode even without the aforemention enhancement. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/231060 Title: packages dnsmasq and libvirt-bin conflict with each other To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/231060/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 231060] Re: packages dnsmasq and libvirt-bin conflict with each other

From the SRU justification: Regression potential: There should be none, since we are simply telling the system-wide dnsmasq (if any) not to bind to the virbr0 which our own dnsmasq instance will bind to. There is more risk of trouble than that.

@Thomas, I'm probably wrong, but are you sure that vnet0 needs to be listed? vnet0 is usually a nic bridged to either br0 or virbr0. i would think that dnsmasq would ignore bridged interfaces. In fact, using just 'except-interface=virbr0' I brought up a kvm guest (which had vnet0 as its nic on the host), and the libvirt dnsmasq was the one to provide it with an ip address. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/231060 Title: packages dnsmasq and libvirt-bin conflict with each other To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/231060/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

The latter included bind-interfaces except-interface=virbr0 whereas to fix #231060 the following would be needed. bind-interfaces except-interface=vnet0 I don't have the power to revert the status change. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/231060 Title: packages dnsmasq and libvirt-bin conflict with each other To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/231060/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 231060] Re: packages dnsmasq and libvirt-bin conflict with each other
@Thomas, I'm probably wrong, but are you sure that vnet0 needs to be listed? vnet0 is usually a nic bridged to either br0 or virbr0. i would think that dnsmasq would ignore bridged interfaces. In fact, using just 'except-interface=virbr0' I brought up a kvm guest (which had vnet0 as its nic on the host), and the libvirt dnsmasq was the one to provide it with an ip address. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/231060 Title: packages dnsmasq and libvirt-bin conflict with each other To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/231060/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Thomas, 959037 means that this issue potentially exists for everyone, rather than just those few folk with specialised needs (mine having been running both a virtualisation host and a tftp server on the same machine). The main issue being the racy nature of running multiple greedy dnsmasq configurations. There's likely a right way to do it, but it's tricky, especially as most of the potential solutions significantly complicate many of the current user-oriented use cases for dnsmasq. That said, I'm probably not the best person to own this bug any longer, having gotten stalled with the project that required tftp a couple years ago, and so not really trying to solve this. I have another project with TFTP coming up soon, and an running libvirt on the laptop I'd like to use as a server: if I happen to find a generic config that works, I'll post a patch (probably based on the plan outlined above, unless the changes to the code in the meantime are sufficiently large to make that no longer workable). -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/231060 Title: packages dnsmasq and libvirt-bin conflict with each other To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/231060/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

In almost all cases, default mode is better: --bind-interfaces is only there to cope with old platforms which don't support enough socket options to do default mode. The only time when --bind-interfaces works better is when it's desirable to run more than one instance of dnsmasq. This is not possible in default mode, but it does work in bind-interfaces mode, providing than _all_ instances are in bind-interfaces mode, and that they listen on a disjoint set of interfaces. This is what the libvirt package attempts to do, as I understand it: it starts its own dnsmasq in --bind-interfaces mode listening on a virtual interface and it forces any system dnsmasq into --bind-interfaces mode and away from the the virtual interface by dropping a configuration fragment into /etc/dnsmasq.d This method brings the disadvantages of --bind-interfaces to the private libvirt dnsmasq instance (the race condition at start-up) and to the system dnsmasq (which will no longer cope with changes to network interfaces.) Options. 1) Keep doing what you're doing, work around the race condition and accept that installing libvirt will limit the functionality of a system dnsmasq by forcing it into --bind-interfaces mode. 2) Arrange that if libvirt and a system dnsmasq co-exist, libvirt uses the system dnsmasq, rather than starting its own. It should be possible to drop some configuration to make the system dnsmasq do what is needed for libvirt. There's a problem here if libvirt is installed alone and using a private dnsmasq, and then subsequently a system dnsmasq is installed. 3) Make some changes to dnsmasq to improve the situation when two instances are running. This may be possible, but I don't have many clues what could be done. 4) Look at some sort of partitioning in the kernel so that the virtual interface is in some sort of separate partition with effectively two network stacks. A sort of chroot for networking. I don't know if this exists in the Linux container stuff, or could be done. It's not really my area.

[Bug 231060] Re: packages dnsmasq and libvirt-bin conflict with each other
@Simon, Thanks for the guidance. Of the options: 1) This seems least invasive in the short-term 2) There's a few potential issues here. a) Install order, because defaults need to be adjusted, and services may need to restart. Some of this can be handled by triggers, but it requires cooperation (perhaps having some way that dnsmasq-base requires users to drop some file that dns-base can use to restart all users when new ones are installed, or similar awkwardnesses). b) Removal independence: similar to install issues, the packages need to be able to coordinate uninstallation. c) This interferes with use cases where a user wants to use dnsmasq to provide nameservice inside libvirt and to do dhcp/tftp on a local network simultaneously or similar cases: using a single demon makes having multiple configurations difficult. 3) The big item that struck me looking at this was that dnsmasq exits if unable to bind to every interface in wildcard mode: having this instead check error conditoins from bind failures and either internally drop the interface/address from the list of interfaces on which to listen or poll on the interface being available depending on the nature of the bind failue would significantly ease the difficulties of running multiple instances, especially one wildcard instance and one or more bound instances. It also eases the race condition identified in comment #11. Another option would be to extend the D-Bus interface to permit D-Bus to be used to remove addresses or interfaces from the wildcard set to reserve them for use by a non-wildcard dnsmasq, preferably in combination with a D-Bus query on startup to automatically enter non- wildcard mode if there is already a wildcard server active and specifically exclude any addresses or interfaces already claimed by another instance. This seems a lot of longer-term work though. 4) sounds kinda cool, but needing a lot more investigation and code than any of the other options. So, my plan is as follows: 1) Add a dpkg trigger subscription to dnsmasq that calls the initscript with force-reload if new configuration snippets are installed 2) Add a configuration snipped to libvirt that switches to bind- interface by default, and excludes virbr0 This compeltely ignores the race condition between startng virbr0 adn starting dnsmasq, and it doesn't help for any sort of complex configuration (of either libvirt or dnsmasq), but it seems the least impact path to enable simultaneous operation without crippling either tool or needing extensive coding. ** Changed in: libvirt (Ubuntu) Assignee: (unassigned) = Emmet Hikory (persia) ** Changed in: dnsmasq (Ubuntu) Assignee: (unassigned) = Emmet Hikory (persia) ** Changed in: dnsmasq (Ubuntu) Status: Triaged = In Progress ** Changed in: libvirt (Ubuntu) Status: Triaged = In Progress -- packages dnsmasq and libvirt-bin conflict with each other https://bugs.launchpad.net/bugs/231060 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Options. 1) Keep doing what you're doing, work around the race condition and accept that installing libvirt will limit the functionality of a system dnsmasq by forcing it into --bind-interfaces mode. 2) Arrange that if libvirt and a system dnsmasq co-exist, libvirt uses the system dnsmasq, rather than starting its own. It should be possible to drop some configuration to make the system dnsmasq do what is needed for libvirt. There's a problem here if libvirt is installed alone and using a private dnsmasq, and then subsequently a system dnsmasq is installed. 3) Make some changes to dnsmasq to improve the situation when two instances are running. This may be possible, but I don't have many clues what could be done. 4) Look at some sort of partitioning in the kernel so that the virtual interface is in some sort of separate partition with effectively two network stacks. A sort of chroot for networking. I don't know if this exists in the Linux container stuff, or could be done. It's not really my area.

[Bug 231060] Re: packages dnsmasq and libvirt-bin conflict with each other
@Simon, Thanks for the guidance. Of the options: 1) This seems least invasive in the short-term 2) There's a few potential issues here. a) Install order, because defaults need to be adjusted, and services may need to restart. Some of this can be handled by triggers, but it requires cooperation (perhaps having some way that dnsmasq-base requires users to drop some file that dns-base can use to restart all users when new ones are installed, or similar awkwardnesses). b) Removal independence: similar to install issues, the packages need to be able to coordinate uninstallation. c) This interferes with use cases where a user wants to use dnsmasq to provide nameservice inside libvirt and to do dhcp/tftp on a local network simultaneously or similar cases: using a single demon makes having multiple configurations difficult. 3) The big item that struck me looking at this was that dnsmasq exits if unable to bind to every interface in wildcard mode: having this instead check error conditoins from bind failures and either internally drop the interface/address from the list of interfaces on which to listen or poll on the interface being available depending on the nature of the bind failue would significantly ease the difficulties of running multiple instances, especially one wildcard instance and one or more bound instances. It also eases the race condition identified in comment #11. Another option would be to extend the D-Bus interface to permit D-Bus to be used to remove addresses or interfaces from the wildcard set to reserve them for use by a non-wildcard dnsmasq, preferably in combination with a D-Bus query on startup to automatically enter non- wildcard mode if there is already a wildcard server active and specifically exclude any addresses or interfaces already claimed by another instance. This seems a lot of longer-term work though. 4) sounds kinda cool, but needing a lot more investigation and code than any of the other options. So, my plan is as follows: 1) Add a dpkg trigger subscription to dnsmasq that calls the initscript with force-reload if new configuration snippets are installed 2) Add a configuration snipped to libvirt that switches to bind- interface by default, and excludes virbr0 This compeltely ignores the race condition between startng virbr0 adn starting dnsmasq, and it doesn't help for any sort of complex configuration (of either libvirt or dnsmasq), but it seems the least impact path to enable simultaneous operation without crippling either tool or needing extensive coding. ** Changed in: libvirt (Ubuntu) Assignee: (unassigned) = Emmet Hikory (persia) ** Changed in: dnsmasq (Ubuntu) Assignee: (unassigned) = Emmet Hikory (persia) ** Changed in: dnsmasq (Ubuntu) Status: Triaged = In Progress ** Changed in: libvirt (Ubuntu) Status: Triaged = In Progress -- packages dnsmasq and libvirt-bin conflict with each other https://bugs.launchpad.net/bugs/231060 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Implementation of this in libvirt is blocked by a race condition that prevents the use of the --interface argument in libvirt. There is a race condition when using --listen-address that dnsmasq will immediately exit if the interface is not yet visible to userspace, which can often happen with how virbr%d is created.

The problem is not really in libvirt, which calls dnsmasq with the appropriate settings to limit itself to the right interface. It's in dnsmasq, which by default binds to all interfaces, thus preventing the dnsmasq-from-libvirt from serving its addresses. I tend to agree with Soren and Neal : yes, that's a conflict configuration case (like if you install two web servers that try to run on the same port), and yes, since it's not that obvious that libvirt runs a DHCP server, we should try to make the potential problem (and solution) more discoverable by documentation. -- packages dnsmasq and libvirt-bin conflict with each other https://bugs.launchpad.net/bugs/231060 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 231060] Re: packages dnsmasq and libvirt-bin conflict with each other
I suppose the problem is this : libvirt provides DHCP service on the host virtual interface (vnet0...) so that guest VMs can get an address. dnsmasq, by default, listens to all available interfaces, so that includes vnet0. Obviously they conflict by both trying to provide the same service on the same interface. Please test one of the following workarounds: Enable the following line in /etc/dnsmasq.conf (supposing eth0 is the interfaces you want to use dnsmasq on): interface=eth0 Alternatively, enable this line in /etc/dnsmasq.conf (supposing vnet0 is the interface you don't want dnsmasq to perturb): except-interface=vnet0 This should allow dnsmasq and libvirt-bin to run side by side. -- packages dnsmasq and libvirt-bin conflict with each other https://bugs.launchpad.net/bugs/231060 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
