nwfilter: Support for learning a VM's IP address This patch implements support for learning a VM's IP address. It uses the pcap library to listen on the VM's backend network interface (tap) or the physical ethernet device (macvtap) and tries to capture packets with source or destination MAC address of the VM and learn from DHCP Offers, ARP traffic, or first-sent IPv4 packet what the IP address of the VM's interface is. This then allows to instantiate the network traffic filtering rules without the user having to provide the IP parameter somewhere in the filter description or in the interface description as a parameter. This only supports to detect the parameter IP, which is for the assumed single IPv4 address of a VM. There is not support for interfaces that may have multiple IP addresses (IP aliasing) or IPv6 that may then require more than one valid IP address to be detected. A VM can have multiple independent interfaces that each uses a different IP address and in that case it will be attempted to detect each one of the address independently. So, when for example an interface description in the domain XML has looked like this up to now: <interface type='bridge'> <source bridge='mybridge'/> <model type='virtio'/> <filterref filter='clean-traffic'> <parameter name='IP' value='10.2.3.4'/> </filterref> </interface> you may omit the IP parameter: <interface type='bridge'> <source bridge='mybridge'/> <model type='virtio'/> <filterref filter='clean-traffic'/> </interface> Internally I am walking the 'tree' of a VM's referenced network filters and determine with the given variables which variables are missing. Now, the above IP parameter may be missing and this causes a libvirt-internal thread to be started that uses the pcap library's API to listen to the backend interface (in case of macvtap to the physical interface) in an attempt to determine the missing IP parameter. If the backend interface disappears the thread terminates assuming the VM was brought down. In case of a macvtap device a timeout is being used to wait for packets from the given VM (filtering by VM's interface MAC address). If the VM's macvtap device disappeared the thread also terminates. In all other cases it tries to determine the IP address of the VM and will then apply the rules late on the given interface, which would have happened immediately if the IP parameter had been explicitly given. In case an error happens while the firewall rules are applied, the VM's backend interface is 'down'ed preventing it to communicate. Reasons for failure for applying the network firewall rules may that an ebtables/iptables command failes or OOM errors. Essentially the same failure reasons may occur as when the firewall rules are applied immediately on VM start, except that due to the late application of the filtering rules the VM now is already running and cannot be hindered anymore from starting. Bringing down the whole VM would probably be considered too drastic. While a VM's IP address is attempted to be determined only limited updates to network filters are allowed. In particular it is prevented that filters are modified in such a way that they would introduce new variables. A caveat: The algorithm does not know which one is the appropriate IP address of a VM. If the VM spoofs an IP address in its first ARP traffic or IPv4 packets its filtering rules will be instantiated for this IP address, thus 'locking' it to the found IP address. So, it's still 'safer' to explicitly provide the IP address of a VM's interface in the filter description if it is known beforehand. * configure.ac: detect libpcap * libvirt.spec.in: require libpcap[-devel] if qemu is built * src/internal.h: add the new ATTRIBUTE_PACKED define * src/Makefile.am src/libvirt_private.syms: add the new modules and symbols * src/nwfilter/nwfilter_learnipaddr.[ch]: new module being added * src/nwfilter/nwfilter_driver.c src/conf/nwfilter_conf.[ch] src/nwfilter/nwfilter_ebiptables_driver.[ch] src/nwfilter/nwfilter_gentech_driver.[ch]: plu the new functionality in * tests/nwfilterxml2xmltest: extend testing

storage: initial support for linking with libgfapi We support gluster volumes in domain XML, so we also ought to support them as a storage pool. Besides, a future patch will want to take advantage of libgfapi to handle the case of a gluster device holding qcow2 rather than raw storage, and for that to work, we need a storage backend that can read gluster storage volume contents. This sets up the framework. Note that the new pool is named 'gluster' to match a <disk type='network'><source protocol='gluster'> image source already supported in a <domain>; it does NOT match the <pool type='netfs'><source><target type='glusterfs'>, since that uses a FUSE mount to a local file name rather than a network name. This and subsequent patches have been tested against glusterfs 3.4.1 (available on Fedora 19); there are likely bugs in older versions that may prevent decent use of gfapi, so this patch enforces the minimum version tested. A future patch may lower the minimum. On the other hand, I hit at least two bugs in 3.4.1 that will be fixed in 3.5/3.4.2, where it might be worth raising the minimum: glfs_readdir is nicer to use than glfs_readdir_r [1], and glfs_fini should only return failure on an actual failure [2].

Adds CPU selection infrastructure Each driver supporting CPU selection must fill in host CPU capabilities. When filling them, drivers for hypervisors running on the same node as libvirtd can use cpuNodeData() to obtain raw CPU data. Other drivers, such as VMware, need to implement their own way of getting such data. Raw data can be decoded into virCPUDefPtr using cpuDecode() function. When implementing virConnectCompareCPU(), a hypervisor driver can just call cpuCompareXML() function with host CPU capabilities. For each guest for which a driver supports selecting CPU models, it must set the appropriate feature in guest's capabilities: virCapabilitiesAddGuestFeature(guest, "cpuselection", 1, 0) Actions needed when a domain is being created depend on whether the hypervisor understands raw CPU data (currently CPUID for i686, x86_64 architectures) or symbolic names has to be used. Typical use by hypervisors which prefer CPUID (such as VMware and Xen): - convert guest CPU configuration from domain's XML into a set of raw data structures each representing one of the feature policies: cpuEncode(conn, architecture, guest_cpu_config, &forced_data, &required_data, &optional_data, &disabled_data, &forbidden_data) - create a mask or whatever the hypervisor expects to see and pass it to the hypervisor Typical use by hypervisors with symbolic model names (such as QEMU): - get raw CPU data for a computed guest CPU: cpuGuestData(conn, host_cpu, guest_cpu_config, &data) - decode raw data into virCPUDefPtr with a possible restriction on allowed model names: cpuDecode(conn, guest, data, n_allowed_models, allowed_models) - pass guest->model and guest->features to the hypervisor * src/cpu/cpu.c src/cpu/cpu.h src/cpu/cpu_generic.c src/cpu/cpu_generic.h src/cpu/cpu_map.c src/cpu/cpu_map.h src/cpu/cpu_x86.c src/cpu/cpu_x86.h src/cpu/cpu_x86_data.h * configure.in: check for CPUID instruction * src/Makefile.am: glue the new files in * src/libvirt_private.syms: add new private symbols * po/POTFILES.in: add new cpu files containing translatable strings

Introduce new OOM testing support The previous OOM testing support would re-run the entire "main" method each iteration, failing a different malloc each time. When a test suite has 'n' allocations, the number of repeats requires is (n * (n + 1) ) / 2. This gets very large, very quickly. This new OOM testing support instead integrates at the virtTestRun level, so each individual test case gets repeated, instead of the entire test suite. This means the values of 'n' are orders of magnitude smaller. The simple usage is $ VIR_TEST_OOM=1 ./qemuxml2argvtest ... 29) QEMU XML-2-ARGV clock-utc ... OK Test OOM for nalloc=36 .................................... OK 30) QEMU XML-2-ARGV clock-localtime ... OK Test OOM for nalloc=36 .................................... OK 31) QEMU XML-2-ARGV clock-france ... OK Test OOM for nalloc=38 ...................................... OK ... the second lines reports how many mallocs have to be failed, and thus how many repeats of the test will be run. If it crashes, then running under valgrind will often show the problem $ VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest When debugging problems it is also helpful to select an individual test case $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest When things get really tricky, it is possible to request that just specific allocs are failed. eg to fail allocs 5 -> 12, use $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-12 ../run valgrind ./qemuxml2argvtest In the worse case, you might want to know the stack trace of the alloc which was failed then VIR_TEST_OOM_TRACE can be set. If it is set to 1 then it will only print if it thinks a mistake happened. This is often not reliable, so setting it to 2 will make it print the stack trace for every alloc that is failed. $ VIR_TEST_OOM_TRACE=2 VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-5 ../run valgrind ./qemuxml2argvtest 30) QEMU XML-2-ARGV clock-localtime ...

build: more workarounds for if_bridge.h This is a second attempt at fixing the problem first attempted in commit 2df8d99; basically undoing the fact that it was reverted in commit 43cee32f, plus fixing two more issues: the code in configure.ac has to EXACTLY match virnetdevbridge.c with regards to declaring in6 types before using if_bridge.h, and the fact that RHEL 5 has even more conflicts: In file included from util/virnetdevbridge.c:49: /usr/include/linux/in6.h:47: error: conflicting types for 'in6addr_any' /usr/include/netinet/in.h:206: error: previous declaration of 'in6addr_any' was here /usr/include/linux/in6.h:49: error: conflicting types for 'in6addr_loopback' /usr/include/netinet/in.h:207: error: previous declaration of 'in6addr_loopback' was here The rest of this commit message borrows from the original try of 2df8d99: A fresh checkout on a RHEL 6 machine with these packages: kernel-headers-2.6.32-405.el6.x86_64 glibc-2.12-1.128.el6.x86_64 failed to configure with this message: checking for linux/if_bridge.h... no configure: error: You must install kernel-headers in order to compile libvirt with QEMU or LXC support Digging in config.log, we see that the problem is identical to what we fixed earlier in commit d12c2811: configure:98831: checking for linux/if_bridge.h configure:98853: gcc -std=gnu99 -c -g -O2 conftest.c >&5 In file included from /usr/include/linux/if_bridge.h:17, from conftest.c:559: /usr/include/linux/in6.h:31: error: redefinition of 'struct in6_addr' /usr/include/linux/in6.h:48: error: redefinition of 'struct sockaddr_in6' /usr/include/linux/in6.h:56: error: redefinition of 'struct ipv6_mreq' configure:98860: $? = 1 I had not hit it earlier because I was using incremental builds, where config.cache had shielded me from the kernel-headers breakage. * configure.ac (if_bridge.h): Avoid conflicting type definitions. * src/util/virnetdevbridge.c (includes): Also sanitize for RHEL 5.

V3 re-ran "firewall-cmd --state" every time a new rule was added, which was extremely inefficient. V4 uses VIR_ONCE_GLOBAL_INIT to set up a one-time initialization function. The VIR_ONCE_GLOBAL_INIT(x) macro references a static function called vir(Ip|Eb)OnceInit(), which will then be called the first time that the static function vir(Ip|Eb)TablesInitialize() is called (that function is defined for you by the macro). This is thread-safe, so there is no chance of any race. IMPORTANT NOTE: I've left the VIR_DEBUG messages in these two init functions (one for iptables, on for ebtables) as VIR_WARN so that I don't have to turn on all the other debug message just to see these. Even if this patch doesn't need any other modification, those messages need to be changed to VIR_DEBUG before pushing. This one-time initialization works well. However, I've encountered problems with testing: 1) Whenever I have enabled the firewalld service, *all* attempts to call firewall-cmd from within libvirtd end with firewall-cmd hanging internally somewhere. This is *not* the case if firewall-cmd returns non-0 in response to "firewall-cmd --state" (i.e. *that* command runs and returns to libvirt successfully.) 2) If I start libvirtd while firewalld is stopped, then start firewalld later, this triggers libvirtd to reload its iptables rules, however it also spits out a *ton* of complaints about deletion failing (I suppose because firewalld has nuked all of libvirt's rules). I guess we need to suppress those messages (which is a more annoying problem to fix than you might think, but that's another story). 3) I noticed a few times during this long line of errors that firewalld made a complaint about "Resource Temporarily unavailable. Having libvirtd access iptables commands directly at the same time as firewalld is doing so is apparently problematic. 4) In general, I'm concerned about the "set it once and never change it" method - if firewalld is disabled at libvirtd startup, causing libvirtd to always use iptables/ebtables directly, this won't cause *terrible* problems, but if libvirtd decides to use firewall-cmd and firewalld is later disabled, libvirtd will not be able to recover.

nwfilter: Support for learning a VM's IP address This patch implements support for learning a VM's IP address. It uses the pcap library to listen on the VM's backend network interface (tap) or the physical ethernet device (macvtap) and tries to capture packets with source or destination MAC address of the VM and learn from DHCP Offers, ARP traffic, or first-sent IPv4 packet what the IP address of the VM's interface is. This then allows to instantiate the network traffic filtering rules without the user having to provide the IP parameter somewhere in the filter description or in the interface description as a parameter. This only supports to detect the parameter IP, which is for the assumed single IPv4 address of a VM. There is not support for interfaces that may have multiple IP addresses (IP aliasing) or IPv6 that may then require more than one valid IP address to be detected. A VM can have multiple independent interfaces that each uses a different IP address and in that case it will be attempted to detect each one of the address independently. So, when for example an interface description in the domain XML has looked like this up to now: <interface type='bridge'> <source bridge='mybridge'/> <model type='virtio'/> <filterref filter='clean-traffic'> <parameter name='IP' value='10.2.3.4'/> </filterref> </interface> you may omit the IP parameter: <interface type='bridge'> <source bridge='mybridge'/> <model type='virtio'/> <filterref filter='clean-traffic'/> </interface> Internally I am walking the 'tree' of a VM's referenced network filters and determine with the given variables which variables are missing. Now, the above IP parameter may be missing and this causes a libvirt-internal thread to be started that uses the pcap library's API to listen to the backend interface (in case of macvtap to the physical interface) in an attempt to determine the missing IP parameter. If the backend interface disappears the thread terminates assuming the VM was brought down. In case of a macvtap device a timeout is being used to wait for packets from the given VM (filtering by VM's interface MAC address). If the VM's macvtap device disappeared the thread also terminates. In all other cases it tries to determine the IP address of the VM and will then apply the rules late on the given interface, which would have happened immediately if the IP parameter had been explicitly given. In case an error happens while the firewall rules are applied, the VM's backend interface is 'down'ed preventing it to communicate. Reasons for failure for applying the network firewall rules may that an ebtables/iptables command failes or OOM errors. Essentially the same failure reasons may occur as when the firewall rules are applied immediately on VM start, except that due to the late application of the filtering rules the VM now is already running and cannot be hindered anymore from starting. Bringing down the whole VM would probably be considered too drastic. While a VM's IP address is attempted to be determined only limited updates to network filters are allowed. In particular it is prevented that filters are modified in such a way that they would introduce new variables. A caveat: The algorithm does not know which one is the appropriate IP address of a VM. If the VM spoofs an IP address in its first ARP traffic or IPv4 packets its filtering rules will be instantiated for this IP address, thus 'locking' it to the found IP address. So, it's still 'safer' to explicitly provide the IP address of a VM's interface in the filter description if it is known beforehand. * configure.ac: detect libpcap * libvirt.spec.in: require libpcap[-devel] if qemu is built * src/internal.h: add the new ATTRIBUTE_PACKED define * src/Makefile.am src/libvirt_private.syms: add the new modules and symbols * src/nwfilter/nwfilter_learnipaddr.[ch]: new module being added * src/nwfilter/nwfilter_driver.c src/conf/nwfilter_conf.[ch] src/nwfilter/nwfilter_ebiptables_driver.[ch] src/nwfilter/nwfilter_gentech_driver.[ch]: plu the new functionality in * tests/nwfilterxml2xmltest: extend testing

storage: initial support for linking with libgfapi We support gluster volumes in domain XML, so we also ought to support them as a storage pool. Besides, a future patch will want to take advantage of libgfapi to handle the case of a gluster device holding qcow2 rather than raw storage, and for that to work, we need a storage backend that can read gluster storage volume contents. This sets up the framework. Note that the new pool is named 'gluster' to match a <disk type='network'><source protocol='gluster'> image source already supported in a <domain>; it does NOT match the <pool type='netfs'><source><target type='glusterfs'>, since that uses a FUSE mount to a local file name rather than a network name. This and subsequent patches have been tested against glusterfs 3.4.1 (available on Fedora 19); there are likely bugs in older versions that may prevent decent use of gfapi, so this patch enforces the minimum version tested. A future patch may lower the minimum. On the other hand, I hit at least two bugs in 3.4.1 that will be fixed in 3.5/3.4.2, where it might be worth raising the minimum: glfs_readdir is nicer to use than glfs_readdir_r [1], and glfs_fini should only return failure on an actual failure [2].

build: add configure option to disable gnulib tests The gnulib testsuite is relatively stable - the only times it is likely to have a test change from pass to fail is on a gnulib submodule update or a major system change (such as moving from Fedora 18 to 19, or other large change to libc). While it is an important test for end users on arbitrary machines (to make sure that the portability glue works for their machine), it mostly wastes time for development testing (as most developers aren't making any of the major changes that would cause gnulib tests to alter behavior). Thus, it pays to make the tests optional at configure time, defaulting to off for development, on for tarballs, with autobuilders requesting it to be on. It also helps to allow a make-time override, via VIR_TEST_EXPENSIVE=[01] (much the way automake sets up V=[01] for overriding the configure time default of how verbose to be). Automake has some pretty hard-coded magic with regards to the TESTS variable; I had quite a job figuring out how to keep 'make distcheck' passing regardless of the configure option setting in use, while still disabling the tests at runtime when I did not configure them on and did not use the override variable. Thankfully, we require GNU make, which lets me hide some information from Automake's magic handling of TESTS. * bootstrap.conf (bootstrap_epilogue): Munge gnulib test variable. * configure.ac (--enable-expensive-tests): Add new enable switch.

add 802.1Qbh and 802.1Qbg handling This patch that adds support for configuring 802.1Qbg and 802.1Qbh switches. The 802.1Qbh part has been successfully tested with real hardware. The 802.1Qbg part has only been tested with a (dummy) server that 'behaves' similarly to how we expect lldpad to 'behave'. The following changes were made during the development of this patch: - Merging Scott's v13-pre1 patch - Fixing endptr related bug while using virStrToLong_ui() pointed out by Jim Meyering - Addressing Jim Meyering's comments to v11 - requiring mac address to the vpDisassociateProfileId() function to pass it further to the 802.1Qbg disassociate part (802.1Qbh untouched) - determining pid of lldpad daemon by reading it from /var/run/libvirt.pid (hardcode as is hardcode alson in lldpad sources) - merging netlink send code for kernel target and user space target (lldpad) using one function nlComm() to send the messages - adding a select() after the sending and before the reading of the netlink response in case lldpad doesn't respond and so we don't hang - when reading the port status, in case of 802.1Qbg, no status may be received while things are 'in progress' and only at the end a status will be there. - when reading the port status, use the given instanceId and vf to pick the right IFLA_VF_PORT among those nested under IFLA_VF_PORTS. - never sending nor parsing IFLA_PORT_SELF type of messages in the 802.1Qbg case - iterating over the elements in a IFLA_VF_PORTS to pick the right IFLA_VF_PORT by either IFLA_PORT_PROFILE and given profileId (802.1Qbh) or IFLA_PORT_INSTANCE_UUID and given instanceId (802.1Qbg) and reading the current status in IFLA_PORT_RESPONSE. - recycling a previous patch that adds functionality to interface.c to - get the vlan identifier on an interface - get the flags of an interface and some convenience function to check whether an interface is 'up' or not (not currently used here) - adding function to determine the root physical interface of an interface. For example if a macvtap is linked to eth0.100, it will find eth0. Also adding a function that finds the vlan on the 'way to the root physical interface' - conveying the root physical interface name and index in case of 802.1Qbg - conveying mac address of macvlan device and vlan identifier in IFLA_VFINFO_LIST[ IFLA_VF_INFO[ IFLA_VF_MAC(mac), IFLA_VF_VLAN(vlan) ] ] to (future) lldpad via netlink - To enable build with --without-macvtap rename the [dis|]associatePortProfileId functions, prepend 'vp' before their name and make them non-static functions. - Renaming variable multicast to nltarget_kernel and inverting the logic - Addressing Jim Meyering's comments; this also touches existing code for example for correcting indentation of break statements or simplification of switch statements. - Renamed occurrencvirVirtualPortProfileDef to virVirtualPortProfileParamses - 802.1Qbg part prepared for sending a RTM_SETLINK and getting processing status back plus a subsequent RTM_GETLINK to get IFLA_PORT_RESPONSE. Note: This interface for 802.1Qbg may still change - [David Allan] move getPhysfn inside IFLA_VF_PORT_MAX to avoid compiler warning when latest if_link.h isn't available - move from Stefan's 802.1Qb{g|h} XML v8 to v9 - move hostuuid and vf index calcs to inside doPortProfileOp8021Qbh - remove debug fprintfs - use virGetHostUUID (thanks Stefan!) - fix compile issue when latest if_link.h isn't available - change poll timeout to 10s, at 1/8 intervals - if polling times out, log msg and return -ETIMEDOUT - Add Stefan's code for getPortProfileStatus - Poll for up to 2 secs for port-profile status, at 1/8 sec intervals: - if status indicates error, abort openMacvtapTap - if status indicates success, exit polling - if status is "in-progress" after 2 secs of polling, exit polling loop silently, without error My patch finishes out the 802.1Qbh parts, which Stefan had mostly complete. I've tested using the recent kernel updates for VF_PORT netlink msgs and enic for Cisco's 10G Ethernet NIC. I tested many VMs, each with several direct interfaces, each configured with a port-profile per the XML. VM-to-VM, and VM-to-external work as expected. VM-to-VM on same host (using same NIC) works same as VM-to-VM where VMs are on diff hosts. I'm able to change settings on the port-profile while the VM is running to change the virtual port behaviour. For example, adjusting a QoS setting like rate limit. All VMs with interfaces using that port-profile immediatly see the effect of the change to the port-profile. I don't have a SR-IOV device to test so source dev is a non-SR-IOV device, but most of the code paths include support for specifing the source dev and VF index. We'll need to complete this by discovering the PF given the VF linkdev. Once we have the PF, we'll also have the VF index. All this info- mation is available from sysfs.

storage: initial support for linking with libgfapi We support gluster volumes in domain XML, so we also ought to support them as a storage pool. Besides, a future patch will want to take advantage of libgfapi to handle the case of a gluster device holding qcow2 rather than raw storage, and for that to work, we need a storage backend that can read gluster storage volume contents. This sets up the framework. Note that the new pool is named 'gluster' to match a <disk type='network'><source protocol='gluster'> image source already supported in a <domain>; it does NOT match the <pool type='netfs'><source><target type='glusterfs'>, since that uses a FUSE mount to a local file name rather than a network name. This and subsequent patches have been tested against glusterfs 3.4.1 (available on Fedora 19); there are likely bugs in older versions that may prevent decent use of gfapi, so this patch enforces the minimum version tested. A future patch may lower the minimum. On the other hand, I hit at least two bugs in 3.4.1 that will be fixed in 3.5/3.4.2, where it might be worth raising the minimum: glfs_readdir is nicer to use than glfs_readdir_r [1], and glfs_fini should only return failure on an actual failure [2].

network: use firewalld instead of iptables, when available * configure.ac, spec file: firewalld defaults to enabled if dbus is available, otherwise is disabled. If --with_firewalld is explicitly requested and dbus is not available, configure will fail. * bridge_driver: add dbus filters to get the FirewallD1.Reloaded signal and DBus.NameOwnerChanged on org.fedoraproject.FirewallD1. When these are encountered, reload all the iptables reuls of all libvirt's virtual networks (similar to what happens when libvirtd is restarted). * iptables, ebtables: use firewall-cmd's direct passthrough interface when available, otherwise use iptables and ebtables commands. This decision is made once the first time libvirt calls iptables/ebtables, and that decision is maintained for the life of libvirtd. * Note that the nwfilter part of this patch was separated out into another patch by Stefan in V2, so that needs to be revised and re-reviewed as well. ================ All the configure.ac and specfile changes are unchanged from Thomas' V3. V3 re-ran "firewall-cmd --state" every time a new rule was added, which was extremely inefficient. V4 uses VIR_ONCE_GLOBAL_INIT to set up a one-time initialization function. The VIR_ONCE_GLOBAL_INIT(x) macro references a static function called vir(Ip|Eb)OnceInit(), which will then be called the first time that the static function vir(Ip|Eb)TablesInitialize() is called (that function is defined for you by the macro). This is thread-safe, so there is no chance of any race. IMPORTANT NOTE: I've left the VIR_DEBUG messages in these two init functions (one for iptables, on for ebtables) as VIR_WARN so that I don't have to turn on all the other debug message just to see these. Even if this patch doesn't need any other modification, those messages need to be changed to VIR_DEBUG before pushing. This one-time initialization works well. However, I've encountered problems with testing: 1) Whenever I have enabled the firewalld service, *all* attempts to call firewall-cmd from within libvirtd end with firewall-cmd hanging internally somewhere. This is *not* the case if firewall-cmd returns non-0 in response to "firewall-cmd --state" (i.e. *that* command runs and returns to libvirt successfully.) 2) If I start libvirtd while firewalld is stopped, then start firewalld later, this triggers libvirtd to reload its iptables rules, however it also spits out a *ton* of complaints about deletion failing (I suppose because firewalld has nuked all of libvirt's rules). I guess we need to suppress those messages (which is a more annoying problem to fix than you might think, but that's another story). 3) I noticed a few times during this long line of errors that firewalld made a complaint about "Resource Temporarily unavailable. Having libvirtd access iptables commands directly at the same time as firewalld is doing so is apparently problematic. 4) In general, I'm concerned about the "set it once and never change it" method - if firewalld is disabled at libvirtd startup, causing libvirtd to always use iptables/ebtables directly, this won't cause *terrible* problems, but if libvirtd decides to use firewall-cmd and firewalld is later disabled, libvirtd will not be able to recover.

nwfilter: Support for learning a VM's IP address This patch implements support for learning a VM's IP address. It uses the pcap library to listen on the VM's backend network interface (tap) or the physical ethernet device (macvtap) and tries to capture packets with source or destination MAC address of the VM and learn from DHCP Offers, ARP traffic, or first-sent IPv4 packet what the IP address of the VM's interface is. This then allows to instantiate the network traffic filtering rules without the user having to provide the IP parameter somewhere in the filter description or in the interface description as a parameter. This only supports to detect the parameter IP, which is for the assumed single IPv4 address of a VM. There is not support for interfaces that may have multiple IP addresses (IP aliasing) or IPv6 that may then require more than one valid IP address to be detected. A VM can have multiple independent interfaces that each uses a different IP address and in that case it will be attempted to detect each one of the address independently. So, when for example an interface description in the domain XML has looked like this up to now: <interface type='bridge'> <source bridge='mybridge'/> <model type='virtio'/> <filterref filter='clean-traffic'> <parameter name='IP' value='10.2.3.4'/> </filterref> </interface> you may omit the IP parameter: <interface type='bridge'> <source bridge='mybridge'/> <model type='virtio'/> <filterref filter='clean-traffic'/> </interface> Internally I am walking the 'tree' of a VM's referenced network filters and determine with the given variables which variables are missing. Now, the above IP parameter may be missing and this causes a libvirt-internal thread to be started that uses the pcap library's API to listen to the backend interface (in case of macvtap to the physical interface) in an attempt to determine the missing IP parameter. If the backend interface disappears the thread terminates assuming the VM was brought down. In case of a macvtap device a timeout is being used to wait for packets from the given VM (filtering by VM's interface MAC address). If the VM's macvtap device disappeared the thread also terminates. In all other cases it tries to determine the IP address of the VM and will then apply the rules late on the given interface, which would have happened immediately if the IP parameter had been explicitly given. In case an error happens while the firewall rules are applied, the VM's backend interface is 'down'ed preventing it to communicate. Reasons for failure for applying the network firewall rules may that an ebtables/iptables command failes or OOM errors. Essentially the same failure reasons may occur as when the firewall rules are applied immediately on VM start, except that due to the late application of the filtering rules the VM now is already running and cannot be hindered anymore from starting. Bringing down the whole VM would probably be considered too drastic. While a VM's IP address is attempted to be determined only limited updates to network filters are allowed. In particular it is prevented that filters are modified in such a way that they would introduce new variables. A caveat: The algorithm does not know which one is the appropriate IP address of a VM. If the VM spoofs an IP address in its first ARP traffic or IPv4 packets its filtering rules will be instantiated for this IP address, thus 'locking' it to the found IP address. So, it's still 'safer' to explicitly provide the IP address of a VM's interface in the filter description if it is known beforehand. * configure.ac: detect libpcap * libvirt.spec.in: require libpcap[-devel] if qemu is built * src/internal.h: add the new ATTRIBUTE_PACKED define * src/Makefile.am src/libvirt_private.syms: add the new modules and symbols * src/nwfilter/nwfilter_learnipaddr.[ch]: new module being added * src/nwfilter/nwfilter_driver.c src/conf/nwfilter_conf.[ch] src/nwfilter/nwfilter_ebiptables_driver.[ch] src/nwfilter/nwfilter_gentech_driver.[ch]: plu the new functionality in * tests/nwfilterxml2xmltest: extend testing
