Since nparams can be technically negative, it is a good practice throughout
our code to check if nparams actually has a non-negative value. The same effect
would be achieved by converting our internal typed params serializer argument
to 'unsigned' type, but it definitely would not be the path of least resistance.

When virHostValidateCPUFlag returns NULL, that's more an unexpected
error than the sign of missing CPU flags. Let's react to this
appropriately.

Now that we have all the pieces in place, we can add the 'iothread=#' to
the command line for the (two) controllers that support it (virtio-scsi-pci
and virtio-scsi-ccw). Add the tests as well...
Rather than an if statement, use a switch.
The switch will also catch the illegal usage of 'iothread' with some other
kind of unsupported bus configuration.
Add the ability to add an 'iothread' to the controller which will be how
virtio-scsi-pci and virtio-scsi-ccw iothreads have been implemented in qemu.
Describe the new functionality and add tests to parse/validate that the
new attribute can be added.
Previous commit moved some lists out of the -devel package
and into the -docs package
commit feffcc03a0
Author: Cole Robinson <crobinso@redhat.com>
Date: Wed Apr 13 10:37:42 2016 -0400
spec: Only pull in API docs with -devel package
What was not realized is that the rule 'libvirt-docs/*'
and ' docs/*.html docs/html docs/*.gif' actually point
to the exact same content. ie, we had previously included
the website HTML in *both* the -docs and -devel packages.
So this change ended up listing the files twice, which
caused RPM to print a load of warnings:

Commits 52a2eef9 and 62be5486 forgot to add these errors to daemon's error
whitelist, i.e. in order to avoid log file pollution with errors like "Domain
not found" or "Server not found" in this case, since these events are valid
and expected to occur.

Rather than be specific about which devices in the <iothreads> description,
let's leave that for the <disk> description for it's <iothread> value.

An iothread for virtio-scsi is a property of the controller. Add a lookup
of the 'virtio-scsi-pci' and 'virtio-scsi-ccw' device properties and parse
the output. For both, support for the iothread was added in qemu 2.4
while support for virtio-scsi in general was added in qemu 1.4.
Modify the various mock capabilities replies (by hand) to reflect the
when virtio-scsi was supported and then specifically when the iothread
property was added. For versions prior to 1.4, use the no device error
return for virtio-scsi. For versions 1.4 to before 2.4, add some data
for virtio-scsi-pci even though it isn't complete we're not looking for
anything specific there anyway. For 2.4 to 2.6, add a more complete reply.

We don't need them any longer; moreover, the previous structure
made it very easy for bugs to slip in, by having the result of one
check influence the following one.
By placing the check for "$with_init_script" = check front and
center, hopefully this won't happen (as easily) again.
Expose a public API to retrieve some identity and connection information about
a client connected to the specified server on daemon. The identity info
retrieved is mostly connection transport dependent, i.e. there won't be any
socket address returned for a local (UNIX socket) connection, while on the
other hand, when connected through TLS or unencrypted TCP, obviously no UNIX
process identification will be present in the returned data. All supported
values that can be returned in typed params are exposed and documented in
include/libvirt/libvirt-admin.h

This method just aggregates various client object attributes, like socket
address, connection type (RO/RW), and some TCP/TLS/UNIX identity in an atomic
manner.

We do have a similar method, serving the same purpose, for TLS, but we lack
one for SASL. So introduce one, in order for other modules to be able to find
out, if a SASL session is active, or better said, that a SASL session exists
at all.

Our socket address format is in a rather non-standard format and that is
because sasl library requires the IP address and service to be delimited by a
semicolon. The string form is a completely internal matter, however once the
admin interfaces to retrieve client identity information are merged, we should
return the socket address string in a common format, e.g. format defined by
URI rfc-3986, i.e. the IP address and service are delimited by a colon and
in case of an IPv6 address, square brackets are added:
Examples:
127.0.0.1:1234
[::1]:1234
This patch changes our default format to the one described above, while adding
separate methods to request the non-standard SASL format using semicolon as a
delimiter.

This patch could easily be squashed with the virAdmClientGetInfo method
introduced later one, but the idea was to split the logic to as many preferably
independent patches as possible. As the subject hints, this patch defines
some public typed params-related macros used within virAdmClientGetInfo
method. The thing is, there's one identity attribute missing in the set --
SELinux context, which libvirt internally supports in virIdentity, but it
doesn't seem to do much (or anything at all), so there's some room to extend
the set in the future.

Just like with server-related APIs, before any of client-based APIs can be
called, a reference to a client-side client object needs to be obtained. For
this purpose, a lookup method should exist. Apart from the client retrieval
logic, a new error code for non-existent client had to be added as well.

This adds a ports= attribute to usb controller XML, like
<controller type='usb' model='nec-xhci' ports='8'/>
This maps to:
qemu -device nec-usb-xhci,p2=8,p3=8
Meaning, 8 ports that support both usb2 and usb3 devices. Gerd
suggested to just expose them as one knob.

In these functions I'm fixing here, we do call
qemuMonitorJSONCheckError() followed by another check if qemu
reply contains 'return' object. If it wouldn't, the former
CheckError() function would error out and the flow would not even
get to the latter.

Usually, the flow in this area of the code is as follows:
qemuMonitorJSONMakeCommand()
qemuMonitorJSONCommand()
qemuMonitorJSONCheckError()
parseReply()
But in this function, for some reasons, the last two steps were
swapped. This makes no sense.

In qemuDomainDefAddDefaultDevices we check for a non-NULL
def->os.machine for x86 archs, but not the others.
Moreover, the only caller - qemuDomainDefPostParse
already checks for it and even then it can happen only
if /etc/libvirt contains an XML without a machine type.
We do not need to propagate the exact return values
and the only possible ones are 0 and -1 anyway.
Remove the temporary variable and use the usual pattern:
if (f() < 0)
return -1;

Thing is, for some reasons you can have your domain's RTC to be
in something different than UTC. More weirdly, it's not only time
zone what you can shift it of, but an arbitrary value. So, if
domain is configured that way, libvirt will correctly put it onto
qemu cmd line and moreover track it as this offset changes during
domain's life time (e.g. because guest OS decides the best thing
to do is set new time to RTC). Anyway, they way in which this
tracking is implemented is events. But we've got a problem if
change in guest's RTC occurs and the daemon is not running. The
event is lost and we end up reporting invalid value in domain
XML. Therefore, when the daemon is starting up again and it is
reconnecting to all running domains, re-fetch their RTC so the
correct offset value can be computed.

Wire-up the public client listing API. Along with this change, a private time
simple conversion method to interpret client's timestamp obtained from server
has been added as well. Format used to for time output is as follows:
YYYY-mm-DD HH:MM:SS+ZZZZ.
Although libvirt exposes methods time-related methods through virtime.h
internally, it utilizes millisecond precision which we don't need in this case,
especially when connection timestamps use precision to seconds only.
This is just a convenience int to string conversion method.
To reflect the new API, man page has been adjusted accordingly.
