use /var/lib/libvirt/dnsmasq since /var/lib/libvirt/network is

This patch makes libvirtd start the dnsmasq daemon with a
--dhcp-hostsfile option instead of --dhcp-host options for each
'//ip/dhcp/host' entries defined in network xml file.
the dnsmasq host file is stored into /var/lib/libvirt/network
* src/network/bridge_driver.c: define the directory for the hostfiles
and save/delete them to be used by dnsmasq
The virConnectPtr is no longer required for error reporting since
that is recorded in a thread local. Remove use of virConnectPtr

match

Long ago we tried to use Fedora's lokkit utility in order to register
our iptables rules so that 'service iptables restart' would
automatically load our rules.
There was one fatal flaw - if the user had configured iptables without
lokkit, then we would clobber that configuration by running lokkit.
We quickly disabled lokkit support, but never removed it. Let's do
that now.
The 'my virtual network stops working when I restart iptables' still
remains. For all the background on this saga, see:
https://bugzilla.redhat.com/227011
* src/util/iptables.c: remove lokkit support
* configure.in: remove --enable-lokkit
* libvirt.spec.in: remove the dirs used only for saving rules for lokkit
* src/Makefile.am: ditto
* src/libvirt_private.syms, src/network/bridge_driver.c,
src/util/iptables.h: remove references to iptablesSaveRules
This is the expected behaviour, I think - reloading libvirtd should
be a subset of restarting it.
Note, we reload the rules after we've determined which networks
are active (because we only add the rules for active networks)
and before we start autostart networks (to avoid re-adding the
rules).
* src/network/bridge_driver.c: reload iptables rules on startup
Currently, when we add iptables rules, we keep them on a list so that
we can easily reload them on e.g. 'service libvirtd reload'.
However, we don't save this list to disk, so if libvirtd is restarted
we lose the ability to reload the rules.
The fix is simple - just re-add the damn things on reload.
Note, we delete the rules before re-adding them, just like the current
behaviour of iptRulesReload().
* src/network/bridge_driver.c: re-add the iptables rules on reload.
Introduce a number of new APIs to expose some boolean properties
of objects, which cannot otherwise reliably determined, nor are
aspects of the XML configuration.
* virDomainIsActive: Checking virDomainGetID is not reliable
since it is not possible to distinguish between error condition
and inactive domain for ID of -1.
* virDomainIsPersistent: Check whether a persistent config exists
for the domain
* virNetworkIsActive: Check whether the network is active
* virNetworkIsPersistent: Check whether a persistent config exists
for the network
* virStoragePoolIsActive: Check whether the storage pool is active
* virStoragePoolIsPersistent: Check whether a persistent config exists
for the storage pool
* virInterfaceIsActive: Check whether the host interface is active
* virConnectIsSecure: whether the communication channel to the
hypervisor is secure
* virConnectIsEncrypted: whether any network based commnunication
channels are encrypted
NB, a channel can be secure, even if not encrypted, eg if it does
not involve the network, like a UNIX socket, or pipe.
* include/libvirt/libvirt.h.in: Define public API
* src/driver.h: Define internal driver API
* src/libvirt.c: Implement public API entry point

deriving the maximum number of leases
The LXC driver was mistakenly returning -1 for lxcStartup()
in scenarios that are not an error. This caused the libvirtd
to quit for unprivileged users. This fixes the return code
of LXC driver, and also adds a "name" field to the virStateDriver
struct and logging to make it easier to find these problems
in the future
* src/driver.h: Add a 'name' field to state driver to allow
easy identification during failures
* src/libvirt.c: Log name of failed driver for virStateInit
failures
* src/lxc/lxc_driver.c: Don't return a failure code for
lxcStartup() if LXC is not available on this host, simply
disable the driver.

src/uml/uml_driver.c, src/xen/xen_driver.c: Fill in name

Rename virDomainIsActive to virDomainObjIsActive, and
virInterfaceIsActive to virInterfaceObjIsActive and finally
virNetworkIsActive to virNetworkObjIsActive.

src/test/test_driver.c, src/uml/uml_driver.c: Update for
renamed APIs.
Nearly all of the methods in src/util/util.h have error codes that
must be checked by the caller to correct detect & report failure.
Add ATTRIBUTE_RETURN_CHECK to ensure compile time validation of
this
* daemon/libvirtd.c: Add explicit check on return value of virAsprintf
* src/conf/domain_conf.c: Add missing check on virParseMacAddr return
value status & report error
* src/network/bridge_driver.c: Add missing OOM check on virAsprintf
and report error
* src/qemu/qemu_conf.c: Add missing check on virParseMacAddr return
value status & report error
* src/security/security_selinux.c: Remove call to virRandomInitialize
that's done in libvirt.c already
* src/storage/storage_backend_logical.c: Add check & log on virRun
return status
* src/util/util.c: Add missing checks on virAsprintf/Run status
* src/util/util.h: Annotate all methods with ATTRIBUTE_RETURN_CHECK
if they return an error status code
* src/vbox/vbox_tmpl.c: Add missing check on virParseMacAddr
* src/xen/xm_internal.c: Add missing checks on virAsprintf
* tests/qemuargv2xmltest.c: Remove bogus call to virRandomInitialize()
This patch adds an optional attribute to the <bootp> tag, that
allows to specify a TFTP server address other than the address of
the DHCP server itself.
This can be used to forward the BOOTP settings of the host down to the
guest. This is something that configurations such as Xen's default
network achieve naturally, but must be done manually for NAT.
* docs/formatnetwork.html.in: Document new attribute.
* docs/schemas/network.rng: Add it to schema.
* src/conf/network_conf.h: Add it to struct.
* src/conf/network_conf.c: Add it to parser and pretty printer.
* src/network/bridge_driver.c: Put it in the dnsmasq command line.
* tests/networkxml2xmlin/netboot-proxy-network.xml
tests/networkxml2xmlout/netboot-proxy-network.xml
tests/networkxml2xmltest.c: add new tests
Currently, libvirtd will start a dnsmasq process for the virtual
network, but (aside from killing the dnsmasq process and replacing it),
there's no way to define tftp boot options.
This change introduces the appropriate tags to the dhcp configuration:
<network>
<name>default</name>
<bridge name="virbr%d" />
<forward/>
<ip address="192.168.122.1" netmask="255.255.255.0">
<tftp root="/var/lib/tftproot" />
<dhcp>
<range start="192.168.122.2" end="192.168.122.254" />
<bootp file="pxeboot.img"/>
</dhcp>
</ip>
</network>
When the attributes are present, these are passed to the
arguments to dnsmasq:
dnsmasq [...] --enable-tftp --tftp-root /srv/tftp --dhcp-boot pxeboot.img
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^
from <tftp /> from <bootp />
At present, only local tftp servers are supported (ie, dnsmasq runs as
the tftp server), but we could improve this in future by adding a
server= attribute.
