dnl Make automake keep quiet about wildcards & other GNUmake-isms; also keep
dnl quiet about the fact that we intentionally cater to automake 1.9
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.

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.

Prevent crash from dlclose() of libvirt.so
When libvirt calls virInitialize it creates a thread local
for the virErrorPtr storage, and registers a callback to
cleanup memory when a thread exits. When libvirt is dlclose()d
or otherwise made non-resident, the callback function is
removed from memory, but the thread local may still exist
and if a thread later exists, it will invoke the callback
and SEGV. There may also be other thread locals with callbacks
pointing to libvirt code, so it is in general never safe to
unload libvirt.so from memory once initialized.

Prevent crash from dlclose() of libvirt.so
When libvirt calls virInitialize it creates a thread local
for the virErrorPtr storage, and registers a callback to
cleanup memory when a thread exits. When libvirt is dlclose()d
or otherwise made non-resident, the callback function is
removed from memory, but the thread local may still exist
and if a thread later exists, it will invoke the callback
and SEGV. There may also be other thread locals with callbacks
pointing to libvirt code, so it is in general never safe to
unload libvirt.so from memory once initialized.

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

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 ... OK

Introduce support for parsing/formatting Xen xl config format
Introduce a parser/formatter for the xl config format. Since the
deprecation of xm/xend, the VM config file format has diverged as
new features are added to libxl. This patch adds support for parsing
and formating the xl config format. It supports the existing xm config
format, plus adds support for spice graphics and xl disk config syntax.
Disk config is specified a bit differently in xl as compared to xm. In
xl, disk config consists of comma-separated positional parameters and
keyword/value pairs separated by commas. Positional parameters are
specified as follows
target, format, vdev, access
Supported keys for key=value options are
devtype, backendtype
The positional paramters can also be specified in key/value form. For
example the following xl disk config are equivalent
/dev/vg/guest-volume,,hda
/dev/vg/guest-volume,raw,hda,rw
format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume
See $xen_sources/docs/misc/xl-disk-configuration.txt for more details.
xl disk config is parsed with the help of xlu_disk_parse() from
libxlutil, libxl's utility library. Although the library exists
in all Xen versions supported by the libxl virt driver, only
recently has the corresponding header file been included. A check
for the header is done in configure.ac. If not found, xlu_disk_parse()
is declared externally.

build: avoid -lgcrypt with newer gnutls

Newer gnutls uses nettle, rather than gcrypt, which is a lot nicer
regarding initialization. Yet we were unconditionally initializing
gcrypt even when gnutls wouldn't be using it, and having two crypto
libraries linked into libvirt.so is pointless, but mostly harmless
(it doesn't crash, but does interfere with certification efforts).
There are three distinct version ranges to worry about when
determining which crypto lib gnutls uses, per these gnutls mails:
2.12: http://lists.gnu.org/archive/html/gnutls-devel/2011-03/msg00034.html
3.0: http://lists.gnu.org/archive/html/gnutls-devel/2011-07/msg00035.html
If pkg-config can prove version numbers and/or list the crypto
library used for static linking, we have our proof; if not, it
is safer (even if pointless) to continue to use gcrypt ourselves.
* configure.ac (WITH_GNUTLS): Probe whether to add -lgcrypt, and
define a witness WITH_GNUTLS_GCRYPT.
* src/libvirt.c (virTLSMutexInit, virTLSMutexDestroy)

build: avoid -lgcrypt with newer gnutls
https://bugzilla.redhat.com/show_bug.cgi?id=951637
Newer gnutls uses nettle, rather than gcrypt, which is a lot nicer
regarding initialization. Yet we were unconditionally initializing
gcrypt even when gnutls wouldn't be using it, and having two crypto
libraries linked into libvirt.so is pointless, but mostly harmless
(it doesn't crash, but does interfere with certification efforts).
There are three distinct version ranges to worry about when
determining which crypto lib gnutls uses, per these gnutls mails:
2.12: http://lists.gnu.org/archive/html/gnutls-devel/2011-03/msg00034.html
3.0: http://lists.gnu.org/archive/html/gnutls-devel/2011-07/msg00035.html
If pkg-config can prove version numbers and/or list the crypto
library used for static linking, we have our proof; if not, it
is safer (even if pointless) to continue to use gcrypt ourselves.
* configure.ac (WITH_GNUTLS): Probe whether to add -lgcrypt, and
define a witness WITH_GNUTLS_GCRYPT.
* src/libvirt.c (virTLSMutexInit, virTLSMutexDestroy)
(virTLSMutexLock, virTLSMutexUnlock, virTLSThreadImpl)
(virGlobalInit): Honor the witness.
* libvirt.spec.in (BuildRequires): Make gcrypt usage conditional,
no longer needed in Fedora 19.

network: use firewalld instead of iptables, when available

* 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.

Add dtrace static probes in libvirtd
Adds initial support for dtrace static probes in libvirtd
daemon, assuming use of systemtap dtrace compat shim on
Linux. The probes are inserted for network client connect,
disconnect, TLS handshake states and authentication protocol
states.
This can be tested by running the xample program and then
attempting to connect with any libvirt client (virsh,
virt-manager, etc).

Client fd=44 auth polkit deny pid:24997,uid:500
Client fd=44 disconnected
Client fd=46 connected readonly=1
Client fd=46 auth sasl allow test
Client fd=46 disconnected
The libvirtd.stp file should also really not be required,
since it is duplicated info that is already available in
the main probes.d definition file. A script to autogenerate
the .stp file is needed, either in libvirtd tree, or better
as part of systemtap itself.

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.

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.

Introduce an LXC specific public API & library
This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.
The actual APIs are
int virDomainLxcOpenNamespace(virDomainPtr domain,
int **fdlist,
unsigned int flags);
int virDomainLxcEnterNamespace(virDomainPtr domain,
unsigned int nfdlist,
int *fdlist,
unsigned int *noldfdlist,
int **oldfdlist,
unsigned int flags);
which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.
NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.

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.
