virTypedParameterAssign steals the string rather than copying it into
the typed parameter and thus freeing it leads to a crash when attempting
to serialize the results.

This was introduced in commit 9f50f6e2 and later made an universal
helper in 32e6339c.

Some code paths already assume that it is allocated since it was always
allocated by virDomainPerfDefParseXML. Make it member of virDomainDef
directly so that we don't have to allocate it all the time.

This fixes crash when attempting to connect to an existing process via
virDomainQemuAttach since we would not allocate it in that code path.

The commit "qemu: hot-plug: Assume support for -device in
qemuDomainAttachSCSIDisk" dropped the code for the automatic SCSI
controller creation used in SCSI disk hot-plugging. If we are
hot-plugging a SCSI disk to a domain and there is no proper SCSI
controller defined, it results in an "error: internal error: Could not
find scsi controller with index X required for device" error.

For that reason reverting a hunk of the commit
d4d32005.

This patch also adds an extra comment to the code to clarify the
loop.

virNetServerClientGetInfo returns the client's remote address
as a string, which is a part of the client object.

Use VIR_STRDUP to make a copy which can be freely accessed
even after the virNetServerClient object is unlocked.

To reproduce, put a sleep between virObjectUnlock in
virNetServerClientGetInfo and virTypedParamsAddString in
adminClientGetInfo, then close the queried connection during
that sleep.

Consider the following disk for a domain:

    <disk type='volume' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <auth username='libvirt'>
        <secret type='iscsi' usage='libvirtiscsi'/>
      </auth>
      <source pool='iscsi-secret-pool' volume='unit:0:0:0' mode='direct' startupPolicy='optional'/>
      <target dev='sda' bus='scsi'/>
      <readonly/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

Now, startupPolicy is currently not allowed for iscsi disks, so
one would expect an error message to be thrown. But what a
surprise is waiting for users if they try to start up such
domain:

The problem is, in virStorageTranslateDiskSourcePool disk
def->src->auth is freed, but the pointer is not set to NULL. So
later, when qemuProcessStop starts to free the domain definition,
virStorageAuthDefFree() tries to free the memory again, instead
of jumping out immediately.

When a client connects, it is placed into a queue. As soon as it
authenticate, it is taken out of that queue and placed into a
different one. Now, we have a setting in the daemon config file
that allows users to control the length of the queue of yet not
authenticated clients. By default, it has a value 20 but in the
description to the config knob we clam it's zero.

For type='ethernet' interfaces only.

This will apply to any IP address setting that uses
virNetDevIPInfoAddToDev() (which so far is only the guest-side of LXC
type='ethernet' interfaces).

This is place as a sub-element of <source>, where other aspects of the
host-side connection to the network device are located (network or
bridge name, udp listen port, etc). It's a bit odd that the interface
we're configuring with this info is itself named in <target dev='x'/>,
but that ship sailed long ago:

    <interface type='ethernet'>
      <mac address='00:16:3e:0f:ef:8a'/>
      <source>
        <ip address='192.168.122.12' family='ipv4'
            prefix='24' peer='192.168.122.1'/>
        <ip address='192.168.122.13' family='ipv4' prefix='24'/>
        <route family='ipv4' address='0.0.0.0'
               gateway='192.168.122.1'/>
        <route family='ipv4' address='192.168.124.0' prefix='24'
               gateway='192.168.124.1'/>
      </source>
    </interface>

In practice, this will likely only be useful for type='ethernet', so
its presence in any other type of interface is currently forbidden in
the generic device Validate function (but it's been put into the
general population of virDomainNetDef rather than the
ethernet-specific union member so that 1) we can more easily add the
capability to other types, and 2) we can retain the info when set to
an invalid interface type all the way through to validation and report
a proper error, rather than just ignoring it (which is currently what
happens for many other type-specific settings).

(NB: The already-existing configuration of IP info for the guest-side
of interfaces is in subelements directly under <interface>, and the
name of the guest-side interface (when configurable) is in <guest
dev='x'/>).

The peer attribute is used to set the property of the same name in the
interface IP info:

  <interface type='ethernet'>
    ...
    <ip family='ipv4' address='192.168.122.5'
        prefix='32' peer='192.168.122.6'/>
    ...
  </interface>

Note that this element is used to set the IP information on the
*guest* side interface, not the host side interface - that will be
supported in an upcoming patch.

subsequently reverted in commit 1d14b13f).

This patch takes the code out of
lxcContainerRenameAndEnableInterfaces() that adds all IP addresses and
IP routes to the interface, and puts it into a utility function
virNetDevIPInfoAddToDev() in virnetdevip.c so that it can be used by
anyone.

One small change in functionality -
lxcContainerRenameAndEnableInterfaces() previously would add all IP
addresses to the interface while it was still offline, then set the
interface online, and then add the routes. Because I don't want the
utility function to set the interface online, I've moved this up so
the interface is first set online, then IP addresses and routes are
added. This is the same order that the network service from
initscripts (in ifup-ether) does it, so it shouldn't pose any problem
(and hasn't, in the tests that I've run).

It makes more sense to have the logging at the lower level so other
callers can share the goodness.

While removing so much stuff from / touching so many lines in
lxcContainerRenameAndEnableInterfaces() (which used to have this
debug/error logging), label names were changed and it was updated to
use the now-more-common method of initializing ret to -1 (failure),
then setting to 0 right before the cleanup label.

virDomainNetIPInfoParseXML() and virDomainNetIPInfoFormat() are no
longer "unused", so we can now remove the "ATTRIBUTE_UNUSED" from
their definitions, since virDomainNetIPInfoFormat() is now the only
caller of virDomainNetIPsFormat() and virDomainNetRoutesFormat(),
those two functions can simply be subsumed into
virDomainNetIPInfoFormat().
