There is no easy way to test authentication against libvirt. This
commit modifies the test driver to allow simple username/password
authentication.
You modify the test XML by adding:
<node>
...
<auth>
<user password="123456">rich</user>
<user>jane</user>
</auth>
</node>
If there are any /node/auth/user elements, then authentication is
required by the test driver (if none are present, then the test driver
will work as before and not require authentication).
In the example above, two phony users are added:
rich password: 123456
jane no password required
The test driver will demand a username. If the password attribute is
present (or if the username entered is wrong), then the password is
also asked for and checked:
$ virsh -c test://$(pwd)/testnode.xml list
Enter username for localhost: rich
Enter rich's password for localhost: ***

While comparing network and domain events, I noticed that the
test driver had to do a cast in one place and not the other.
For consistency, we should hide the necessary casting as low
as possible in the stack, with everything else using saner
types.
* src/conf/network_event.h (virNetworkEventStateRegisterID): Alter
type.
* src/conf/network_event.c (virNetworkEventStateRegisterID): Hoist
cast here.

Prior to this patch, every test:/// URI has its own event manager,
which means that registering for an event can only ever receive
events from the connection where it issued the API that triggered
the event. But the whole idea of events is to be able to learn
about something where an API call did NOT trigger the action.
In order to actually test asynchronous events, I wanted to be able
to tie multiple test connections to the same state. Use of a file
in a test URI is still per-connection state, but now parallel
connections to test:///default (from the same binary, of course)
now share common state and can affect one another.
The updated testsuite fails without the rest of this patch.
Valgrind didn't report any leaks.

Ever since their introduction (commit 1509b80 in v0.5.0 for
virConnectDomainEventRegister, commit 4445723 in v0.8.0 for
virConnectDomainEventDeregisterAny), the event deregistration
functions have been documented as returning 0 on success;
likewise for older registration (only the newer RegisterAny
must return a non-zero callbackID). And now that we are
adding virConnectNetworkEventDeregisterAny for v1.2.1, it
should have the same semantics.
Fortunately, all of the stateful drivers have been obeying
the docs and returning 0, thanks to the way the remote_driver
tracks things (in fact, the RPC wire protocol is unable to
send a return value for DomainEventRegisterAny, at least not
without adding a new RPC number). Well, except for vbox,
which was always failing deregistration, due to failure to
set the return value to anything besides its initial -1.
But for local drivers, such as test:///default, we've been
returning non-zero numbers; worse, the non-zero numbers have
differed over time. For example, in Fedora 12 (libvirt 0.8.2),
calling Register twice would return 0 and 1 [the callbackID
generated under the hood]; while in Fedora 20 (libvirt 1.1.3),
it returns 1 and 2 [the number of callbacks registered for
that event type]. Since we have changed the behavior over
time, and since it differs by local vs. remote, we can safely
argue that no one could have been reasonably relying on any
particular behavior, so we might as well obey the docs, as well
as prepare callers that might deal with older clients to not be
surprised if the docs are not strictly followed.
For consistency, this patch fixes the code for all drivers,
even though it only makes an impact for vbox and for local
drivers. By fixing all drivers, future copy and paste from
a remote driver to a local driver is less likely to
reintroduce the bug.
Finally, update the testsuite to gain some coverage of the
issue for local drivers, including the first test of old-style
domain event registration via function pointer instead of
event id.

While the public API & wire protocol included the 'detail'
arg for network lifecycle events, the internal event handling
code did not process it. This meant that if a future libvirtd
server starts sending non-0 'detail' args, the current libvirt
client will not process them.

Again stolen from qemu_driver.c, but dropping all the unneeded bits.
This aims to copy all the current qemu validation checks since that's
the most commonly used real driver, but some of the checks are
completely artificial in the test driver.
This only supports creation of internal snapshots for initial
simplicity.
When passing in custom driver XML, allow a block like
<domain xmlns:test='http://libvirt.org/schemas/domain/test/1.0'>
...
<test:runstate>5</test:runstate>
</domain>
This is only read at initial driver start time, and sets the initial
run state of the object. This is handy for UI testing.
It's only wired up for domains, since that's the only conf/
infrastructure that supports namespaces at the moment.
N.B. This had no ill effects as long as O_RDONLY is defined to
to be 0, such that the expression (O_RDONLY < 0) yielded 0
again.

The function that parses custom driver XML was getting pretty unruly,
split the object parsing into their own functions. Rename some variables
to be consistent across each function. This should be functionally
identical.
Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or
'unsigned int', also santizing 'ii', 'jj', 'kk' to use
the normal 'i', 'j', 'k' naming

Currently the virGetHostname() API has a bogus virConnectPtr
parameter. This is because virtualization drivers directly
reference this API in their virDriverPtr tables, tieing its
API design to the public virConnectGetHostname API design.
This also causes problems for access control checks since
these must only be done for invocations from the public
API, not internal invocation.
Remove the bogus virConnectPtr parameter, and make each
hypervisor driver provide a dedicated function for the
driver API impl. This will allow access control checks
to be easily inserted later.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
Ensure that all drivers implementing public APIs use a
naming convention for their implementation that matches
the public API name.
eg for the public API virDomainCreate make sure QEMU
uses qemuDomainCreate and not qemuDomainStart

This patch refactors various places to allow removing of the
defaultConsoleTargetType callback from the virCaps structure.
A new console character device target type is introduced -
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_NONE - to mark that no type was
specified in the XML. This type is at the end converted to the standard
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL. Other types that are
different from this default have to be processed separately in the
device post parse callback.
This patch adds instrumentation that will allow hypervisor drivers to
fill and validate domain and device definitions after parsed by the XML
parser.
With this patch, after the XML is parsed, a callback to the driver is
issued requesting to fill and validate driver specific details of the
configuration. This allows to use sensible defaults and checks on a per
driver basis at the time the XML is parsed.
Two callback pointers are stored in the new virDomainXMLConf object:
* virDomainDeviceDefPostParseCallback (devicesPostParseCallback)
- called for a single device parsed and for every single device in a
domain config. A virDomainDeviceDefPtr is passed along with the
domain definition and virCaps.
* virDomainDefPostParseCallback, (domainPostParseCallback)
- A callback that is meant to process the domain config after it's
parsed. A virDomainDefPtr is passed along with virCaps.
Both types of callbacks support arbitrary opaque data passed for the
callback functions.
Errors may be reported in those callbacks resulting in a XML parsing
failure.
This patch is the result of running:
for i in $(git ls-files | grep -v html | grep -v \.po$ ); do
sed -i -e "s/virDomainXMLConf/virDomainXMLOption/g" -e "s/xmlconf/xmlopt/g" $i
done
and a few manual tweaks.
