build: use automake subdir-objects Automake 2.0 will enable subdir-objects by default; in preparation for that change, automake 1.14 outputs LOADS of warnings: daemon/Makefile.am:38: warning: source file '../src/remote/remote_protocol.c' is in a subdirectory, daemon/Makefile.am:38: but option 'subdir-objects' is disabled automake-1.14: warning: possible forward-incompatibility. automake-1.14: At least a source file is in a subdirectory, but the 'subdir-objects' automake-1.14: automake option hasn't been enabled. For now, the corresponding output automake-1.14: object file(s) will be placed in the top-level directory. However, automake-1.14: this behaviour will change in future Automake versions: they will automake-1.14: unconditionally cause object files to be placed in the same subdirectory automake-1.14: of the corresponding sources. automake-1.14: You are advised to start using 'subdir-objects' option throughout your automake-1.14: project, to avoid future incompatibilities. daemon/Makefile.am:38: warning: source file '../src/remote/lxc_protocol.c' is in a subdirectory, daemon/Makefile.am:38: but option 'subdir-objects' is disabled ... As automake 1.9 also supported this option, and the previous patches fixed up the code base to work with it, it is safe to now turn it on unconditionally. * configure.ac (AM_INIT_AUTOMAKE): Enable subdir-objects. * .gitignore: Ignore .dirstamp directories. * src/Makefile.am (PDWTAGS, *-protocol-struct): Adjust to new subdir-object location of .lo files.

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

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.

Old programs keep working > but new programs cannot be linked with the routines in libc anymore. > Programs in need of RPC functionality must be linked against TI-RPC. > The TI-RPC implemtation is IPv6 enabled and there are other benefits. > > Visible changes of this change include (obviously) the inability to > link > programs using RPC functions without referencing the TI-RPC library, > the > removal of the RPC headers from the glibc headers, and the lack of > symbols defined in <rpc/netdb.h> when <netdb.h> is installed. > Implemented by Ulrich Drepper. (from glibc NEWS) Thus with recent glibc, we need to try linking with -ltirpc when looking for the XDR functions. The daemon also needs to use XDR_CFLAGS to be able to find the XDR headers stored in /usr/include/tirpc. When using TI-RPC, there are some warnings about redundant declarations, but the fix probably belongs in other modules: /usr/include/tirpc/rpc/rpcent.h:68:13: warning: redundant redeclaration of 'setrpcent' [-Wredundant-decls] /usr/include/rpc/netdb.h:53:13: note: previous declaration of 'setrpcent' was here /usr/include/tirpc/rpc/rpcent.h:69:13: warning: redundant redeclaration of 'endrpcent' [-Wredundant-decls] /usr/include/rpc/netdb.h:54:13: note: previous declaration of 'endrpcent' was here /usr/include/tirpc/rpc/rpc.h:84:12: warning: redundant redeclaration of 'bindresvport' [-Wredundant-decls] /usr/include/netinet/in.h:440:12: note: previous declaration of 'bindresvport' was here

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

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.

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.

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.

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
