Useful to set custom forwarders instead of using the contents of /etc/resolv.conf. It helps me to setup dnsmasq as local nameserver to resolve VM domain names from domain 0, when domain option is used.

This resolves the issue that prompted the filing of https://bugzilla.redhat.com/show_bug.cgi?id=928638 (although the request there is for something much larger and more general than this patch). commit f3868259 disabled the forwarding to upstream DNS servers of unresolved DNS requests for names that had no domain, but were just simple host names (no "." character anywhere in the name). While this behavior is frowned upon by DNS root servers (that's why it was changed in libvirt), it is convenient in some cases, and since dnsmasq can be configured to allow it, it must not be strictly forbidden. This patch restores the old behavior, but since it is usually undesirable, restoring it requires specification of a new option in the network config. Adding the attribute "forwardPlainNames='yes'" to the <dns> elemnt does the trick - when that attribute is added to a network config, any simple hostnames that can't be resolved by the network's dnsmasq instance will be forwarded to the DNS servers listed in the host's /etc/resolv.conf for an attempt at resolution (just as any FQDN would be forwarded). When that attribute *isn't* specified, unresolved simple names will *not* be forwarded to the upstream DNS server - this is the default behavior.

This is another cleanup before extracting platform-specific parts from bridge_driver. Rename struct network_driver to _virNetworkDriverState and add appropriate typedefs: virNetworkDriverState and virNetworkDriverStatePtr.

Although SRIOV network cards support setting a vlan tag on their virtual functions, and although setting this vlan tag via a <vlan> element in a domain's <interface> works, setting a vlan tag for these devices in a <network> definition, or in a network <portgroup> definition is also supposed to work (and the comment that validates <vlan> usage even says that!). However, the check to allow it only checked for an openvswitch network, so attempts to add <vlan> to a network of type='hostdev' would fail.

This fixes the problem reported in: https://bugzilla.redhat.com/show_bug.cgi?id=972690 When checking for a collision of a new libvirt network's subnet with any existing routes, we read all of /proc/net/route into memory, then parse all the entries. The function that we use to read this file requires a "maximum length" parameter, which had previously been set to 64*1024. As each line in /proc/net/route is 128 bytes, this would allow for a maximum of 512 entries in the routing table. This patch increases that number to 128 * 100000, which allows for 100,000 routing table entries. This means that it's possible that 12MB would be allocated, but that would only happen if there really were 100,000 route table entries on the system, it's only held for a very short time. Since there is no method of specifying and unlimited max (and that would create a potential denial of service anyway) hopefully this limit is large enough to accomodate everyone.

In order to learn libvirt multiqueue several things must be done: 1) The '/dev/net/tun' device needs to be opened multiple times with IFF_MULTI_QUEUE flag passed to ioctl(fd, TUNSETIFF, &ifr); 2) Similarly, '/dev/vhost-net' must be opened as many times as in 1) in order to keep 1:1 ratio recommended by qemu and kernel folks. 3) The command line construction code needs to switch from 'fd=X' to 'fds=X:Y:...:Z' and from 'vhostfd=X' to 'vhostfds=X:Y:...:Z'. 4) The monitor handling code needs to learn to pass multiple FDs.

network: static route support for <network> This patch adds the <route> subelement of <network> to define a static route. the address and prefix (or netmask) attribute identify the destination network, and the gateway attribute specifies the next hop address (which must be directly reachable from the containing <network>) which is to receive the packets destined for "address/(prefix|netmask)". These attributes are translated into an "ip route add" command that is executed when the network is started. The command used is of the following form: ip route add <address>/<prefix> via <gateway> \ dev <virbr-bridge> proto static metric <metric> Tests are done to validate that the input data are correct. For example, for a static route ip definition, the address must be a network address and not a host address. Additional checks are added to ensure that the specified gateway is directly reachable via this network (i.e. that the gateway IP address is in the same subnet as one of the IP's defined for the network). prefix='0' is supported for both family='ipv4' address='0.0.0.0' netmask='0.0.0.0' or prefix='0', and for family='ipv6' address='::', prefix=0', although care should be taken to not override a desired system default route. Anytime an attempt is made to define a static route which *exactly* duplicates an existing static route (for example, address=::, prefix=0, metric=1), the following error message will be sent to syslog: RTNETLINK answers: File exists This can be overridden by decreasing the metric value for the route that should be preferred, or increasing the metric for the route that shouldn't be preferred (and is thus in place only in anticipation that the preferred route may be removed in the future). Caution should be used when manipulating route metrics, especially for a default route. Note: The use of the command-line interface should be replaced by direct use of libnl so that error conditions can be handled better. But, that is being left as an exercise for another day.

qemu:///session由 Laine Stump 提交于
This should resolve https://bugzilla.redhat.com/show_bug.cgi?id=958907 Recent new addition of code to read/write active network state to the NETWORK_STATE_DIR in the network driver broke startup for qemu:///session. The network driver had several state file paths hardcoded to /var, which could never possibly work in session mode. This patch modifies *all* state files to use a variable string that is set differently according to whether or not we're running privileged. (It turns out that logDir was never used, so it's been completely eliminated.) There are very definitely other problems preventing dnsmasq and radvd from running in non-privileged mode, but it's more consistent to have the directories used by them be determined in the same fashion. NB: I've noted before that the network driver is storing its state (including dnsmasq and radvd state) in /var/lib, while qemu stores its state in /var/run. It would probably have been better if the two matched, but it's been this way for a long time, and changing it would break running installations during an upgrade, so it's best to just leave it as it is.

On the off-chance that creation of persistent configuration file would fail when defining a network that is already started as transient, the code would remove the transient data structure and thus the network.

This isn't strictly speaking a bugfix, but I realized I'd gotten a bit too verbose when I chose the names for VIR_DOMAIN_HOSTDEV_PCI_BACKEND_TYPE_*. This shortens them all a bit.
-
由 Laine Stump 提交于
I remembered to document this bit, but somehow forgot to implement it. This adds <driver name='kvm|vfio'/> as a subelement to the <forward> element of a network (this puts it parallel to the match between mode='hostdev' attribute in a network and type='hostdev' in an <interface>). Since it's already documented, only the parser, formatter, backend driver recognition (it just translates/moves the flag into the <interface> at the appropriate time), and a test case were needed. (I used a separate enum for the values both because the original is defined in domain_conf.h, which is unavailable from network_conf.h, and because in the future it's possible that we may want to support other non-hostdev oriented driver names in the network parser; this makes sure that one can be expanded without the other).

Until now tranisent networks weren't really useful as libvirtd wasn't able to remember them across restarts. This patch adds support for loading status files of transient networks (that already were generated) so that the status isn't lost. This patch chops up virNetworkObjUpdateParseFile and turns it into virNetworkLoadState and a few friends that will help us to load status XMLs and refactors the functions that are loading the configs to use them.

By current implementation, network inbound is required in order to use 'floor' for guaranteeing minimal throughput. This is so, because we want user to tell us the maximal throughput of the network instead of finding out ourselves (and detect bogus values in case of virtual interfaces). However, we are nowadays requiring this only on documentation level. So if user starts a domain with 'floor' set on one its interfaces, we silently ignore the setting. We should error out instead.

Originally, only a host name was used to associate a DHCPv6 request with a specific IPv6 address. Further testing demonstrates that this is an unreliable method and, instead, a client-id or DUID needs to be used. According to DHCPv6 standards, this id can be a duid-LLT, duid-LL, or duid-UUID even though dnsmasq will accept almost any text string. Although validity checking of a specified string makes sure it is hexadecimal notation with bytes separated by colons, there is no rigorous check to make sure it meets the standard.
