Some of our tests try to validate domain XMLs they are working
with (not intentionally, simply because they call top level
domain XML parse function). Anyway, this implies that we build
domain capabilities also - see
virQEMUDriverGetDomainCapabilities(). And since some domain XMLs
are type of 'kvm' the control gets through
virQEMUCapsFillDomainCaps() and virHostCPUGetKVMMaxVCPUs() to
opening /dev/kvm which may be missing on the machine we're
running 'make check'.
Previously, we did not see this issue, because it was masked. If
building domain capabilities failed for whatever reason, we
ignored the failure. Only v5.9.0-207-gc69e6edea3 uncovered the
problem (it changed reval from 0 to -1 if
virQEMUDriverGetDomainCapabilities() fails). Since the referenced
commit is correct, we need to mock access to /dev/kvm in our
tests.

Some layered products such as oVirt have requested a way to avoid being
blocked by guest agent commands when querying a loaded vm. For example,
many guest agent commands are polled periodically to monitor changes,
and rather than blocking the calling process, they'd prefer to simply
time out when an agent query is taking too long.
This patch adds a way for the user to specify a custom agent timeout
that is applied to all agent commands.
One special case to note here is the 'guest-sync' command. 'guest-sync'
is issued internally prior to calling any other command. (For example,
when libvirt wants to call 'guest-get-fsinfo', we first call
'guest-sync' and then call 'guest-get-fsinfo').
Previously, the 'guest-sync' command used a 5-second timeout
(VIR_DOMAIN_QEMU_AGENT_COMMAND_DEFAULT), whereas the actual command that
followed always blocked indefinitely
(VIR_DOMAIN_QEMU_AGENT_COMMAND_BLOCK). As part of this patch, if a
custom timeout is specified that is shorter than
5 seconds, this new timeout is also used for 'guest-sync'. If there is
no custom timeout or if the custom timeout is longer than 5 seconds, we
will continue to use the 5-second timeout.

For some architectures and setups, device removal can take
longer than the default 5 seconds. This results in commands
such as 'virsh setvcpus' to fire timeout messages even if
the operation were successful in the guest, confusing the
user.
This patch sets a new 10 seconds unplug timeout for PPC64
guests. All other archs will keep the default 5 seconds
timeout.
Instead of putting 'if PPC64' conditionals inside qemu_hotplug.c
to set the new timeout value, a new function called
qemuDomainGetUnplugTimeout was added. The timeout value is then
retrieved when needed, by passing the correspondent DomainDef
object. This approach allows for different guest architectures
to have distint unplug timeout intervals, regardless of the
host architecture. This design also makes it easier to
modify/enhance the unplug timeout logic in the future
(allow for special timeouts for TCG domains, for example).
A new mock file was created to work with qemuhotplugtest.c,
given that the test timeout is significantly shorter than
the actual timeout value in qemu_hotplug.c.
The now unused 'qemuDomainRemoveDeviceWaitTime' global can't
be simply erased from qemu_hotplug.c though. Next patch will
remove it properly.

The pconfig feature was enabled in QEMU by accident in 3.1.0. All other
newer versions do not support it and it was removed from the
Icelake-Server CPU model in QEMU.
We don't normally change our CPU models even when QEMU does so to avoid
breaking migrations between different versions of libvirt. But we can
safely do so in this specific case. QEMU never supported enabling
pconfig so any domain which was able to start has pconfig disabled.
With a small compatibility hack which explicitly disables pconfig when
CPU model equals Icelake-Server in migratable domain definition, only
one migration scenario stays broken (and there's nothing we can do about
it): from any host to a host with libvirt < 5.10.0 and QEMU > 3.1.0.

According to rfc3986:
2.3. Unreserved Characters
Characters that are allowed in a URI but do not have a reserved
purpose are called unreserved. These include uppercase and lowercase
letters, decimal digits, hyphen, period, underscore, and tilde.
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
URIs that differ in the replacement of an unreserved character with
its corresponding percent-encoded US-ASCII octet are equivalent: they
identify the same resource. However, URI comparison implementations
do not always perform normalization prior to comparison (see Section
6). For consistency, percent-encoded octets in the ranges of ALPHA
(%41-%5A and %61-%7A), DIGIT (%30-%39), hyphen (%2D), period (%2E),
underscore (%5F), or tilde (%7E) should not be created by URI
producers and, when found in a URI, should be decoded to their
corresponding unreserved characters by URI normalizers.
Thus we must not include few other characters which don't match
c_isalpha to conform to the rules.

Author: Daniel P. Berrange <berrange@redhat.com>
Date: Wed May 9 15:18:56 2012 +0100
Allow stack traces to be included with log messages
Sometimes it is useful to see the callpath for log messages.
This change enhances the log filter syntax so that stack traces
can be show by setting '1:+NAME' instead of '1:NAME'.
With the huge & ever increasing number of logging statements per file,
this will be incredibly verbose and have a major performance penalty.
This makes the feature impractical to use widely and as such it is not
worth the code maint cost.
Removing this seldom used feature allows us to drop the 'execinfo'
module in gnulib which provides the backtrace() function which doesn't
exist on non-Linux.
Users who want to get stack traces of parts of libvirt can use GDB,
or systemtap for live tracing with minimal perf impact.

Converting from virObject to GObject is reasonably straightforward,
as illustrated by this patch for virIdentity
In the header file
- Remove
typedef struct _virIdentity virIdentity
- Add
#define VIR_TYPE_IDENTITY virIdentity_get_type ()
G_DECLARE_FINAL_TYPE (virIdentity, vir_identity, VIR, IDENTITY, GObject);
Which provides the typedef we just removed, and class
declaration boilerplate and various other constants/macros.
In the source file
- Change 'virObject parent' to 'GObject parent' in the struct
- Remove the virClass variable and its initializing call
- Add
G_DEFINE_TYPE(virIdentity, vir_identity, G_TYPE_OBJECT)
which declares the instance & class constructor functions
- Add an impl of the instance & class constructors
wiring up the finalize method to point to our dispose impl
In all files
- Replace VIR_AUTOUNREF(virIdentityPtr) with g_autoptr(virIdentity)
- Replace virObjectRef/Unref with g_object_ref/unref. Note
the latter functions do *NOT* accept a NULL object where as
libvirt's do. If you replace g_object_unref with g_clear_object
it is NULL safe, but also clears the pointer.

Add the main glib.h to internal.h so that all common code can use it.

gmem: clarify that g_malloc always uses the system allocator
Applications can still use custom allocators in general, but they must
do this by linking to a library that replaces the core malloc/free
implemenentation entirely, instead of via a glib specific call.
This means that libvirt does not need to be concerned about use of
g_malloc/g_free causing an ABI change in the public libary, and can
avoid memory copying when talking to external libraries.
This patch probes for glib, which provides the foundation layer with
a collection of data structures, helper APIs, and platform portability
logic.
Later patches will introduce linkage to gobject which provides the
object type system, built on glib, and gio which providing objects
for various interesting tasks, most notably including DBus client
and server support and portable sockets APIs, but much more too.

Linux kernel 5.1 added a new PPC KVM capability named
KVM_PPC_CPU_CHAR_BCCTR_FLUSH_ASSIST, which is exposed to the QEMU guest
since QEMU commit 8ff43ee404d under a new sPAPR capability called
SPAPR_CAP_CCF_ASSIST. This cap indicates whether the processor supports
hardware acceleration for the count cache flush workaround, which
is a software workaround that flushes the count cache on context
switch. If the processor has this hardware acceleration, the software
flush can be shortened, resulting in performance gain.
This hardware acceleration is defaulted to 'off' in QEMU. The reason
is that earlier versions of the Power 9 processor didn't support
it (it is available on Power 9 DD2.3 and newer), and defaulting this
option to 'on' would break migration compatibility between the Power 9
processor class.
However, the user running a P9 DD2.3+ hypervisor might want to create
guests with ccf-assist=on, accepting the downside of only being able
to migrate them only between other P9 DD2.3+ hosts running upstream
kernel 5.1+, to get a performance boost.
This patch adds this new capability to Libvirt, with the name of
QEMU_CAPS_MACHINE_PSERIES_CAP_CCF_ASSIST.

When connecting to qemu's monitor the @vm object is unlocked.
This is justified - connecting may take a long time and we don't
want to wait with the domain object locked. However, just before
the domain object is locked again, the monitor's FD is registered
in the event loop. Therefore, there is a small window where the
event loop has a chance to call a handler for an event that
occurred on the monitor FD but vm is not initalized properly just
yet (i.e. priv->mon is not set). For instance, if there's an
incoming migration, qemu creates its socket but then fails to
initialize (for various reasons, I'm reproducing this by using
hugepages but leaving the HP pool empty) then the following may
happen:
1) qemuConnectMonitor() unlocks @vm
2) qemuMonitorOpen() connects to the monitor socket and by
calling qemuMonitorOpenInternal() which subsequently calls
qemuMonitorRegister() the event handler is installed
3) qemu fails to initialize and exit()-s, which closes the
monitor
4) The even loop sees EOF on the monitor and the control gets to
qemuProcessEventHandler() which locks @vm and calls
processMonitorEOFEvent() which then calls
qemuMonitorLastError(priv->mon). But priv->mon is not set just
yet.
5) qemuMonitorLastError() dereferences NULL pointer
The solution is to unlock the domain object for a shorter time
and most importantly, register event handler with domain object
locked so that any possible event processing is done only after
@vm's private data was properly initialized.
This issue is also mentioned in v4.2.0-99-ga5a777a8ba.
Since we are unlocking @vm and locking it back, another thread
might have destroyed the domain meanwhile. Therefore we have to
check if domain is still active, and we have to do it at the
same place where domain lock is acquired back, i.e. in
qemuMonitorOpen(). This creates a small problem for our test
suite which calls qemuMonitorOpen() directly and passes @vm which
has no definition. This makes virDomainObjIsActive() call crash.
Fortunately, allocating empty domain definition is sufficient.

Use virBufferEscapeShell in virNetSocketNewConnectSSH
to escape the netcat command since it's passed to the shell. Adjust

While the intention of this change was good, the result is broken as it
is still underquoted.
On the SSH server side, SSH itself runs the command via the shell.
Our command is then invoking the shell again. Thus we see
$ virsh -c qemu+ssh://root@domokun/system?netcat=%2Ftmp%2Ffo%20o%2Fnc list
error: failed to connect to the hypervisor
error: End of file while reading data: sh: /tmp/fo: No such file or directory: Input/output error
With the second level of escaping added we can now successfully use a nc
binary with a space in the path.
The original test case added was misleading as it illustrated using a
binary path of 'nc -4' which is not a path, it is a command with a
separate argument, which is getting interpreted as a path.
