126d4123c5 tracing: excise the tcg related from tracetool
Now we have no TCG trace events and no longer handle them in the code
we can remove the handling from the tracetool to generate them. vcpu
tracing is still available although the existing syscall event is an
exercise in redundancy (plugins and -strace can also get the
information).

9e8be4c546 drop libxml2 checks since libxml is not actually used (for parallels)
For a long time, we assumed that libxml2 is necessary for parallels
block format support (block/parallels*). However, this format actually
does not use libxml [*]. Since this is the only user of libxml2 in
whole QEMU tree, we can drop all libxml2 checks and dependencies too.

It is even more: --enable-parallels configure option was the only
option which was silently ignored when it's (fake) dependency
(libxml2) isn't installed.

Drop all mentions of libxml2.

[*] Actually the basis for libxml use were introduced in commit
    ed279a06c5 ("configure: add dependency") but the implementation
    was never merged:

98487b9035 build: make check-block a meson test
"meson test" can be asked to run tests verbosely; this makes it usable
also for qemu-iotests's own harness, and it lets "make check-block"
reuse mtest2make.py's infrastructure to find and build test dependencies.

Adjust check-block.sh to use the standard exit code that reports a test
as skipped.  Alternatively, in the future we could make it produce TAP
output, which is consistent with all other "make check" tests.

761a1a488e qapi: generate trace events by default
We don't generate trace events for tests/ and qga/ because that it is
not simple and not necessary. We have corresponding comments in both
tests/meson.build and qga/meson.build.

Still to not miss possible future qapi code generation call, and not to
forget to enable trace events generation, let's enable it by default.
So, turn option --gen-trace into opposite --no-trace-events and use new
option only in tests/ and qga/ where we already have good comments why
we don't generate trace events code.

Note that this commit enables trace-events generation for qapi-gen.py
call from tests/qapi-schema/meson.build and storage-daemon/meson.build.
Still, both are kind of noop: tests/qapi-schema/ doesn't seem to
generate any QMP command code and no .trace-events files anyway,
storage-daemon/ uses common QMP command implementations and just
generate empty .trace-events

bd2017bc41 qapi/commands: Optionally generate trace for QMP commands
Add trace generation disabled by default and new option --gen-trace to
enable it.  The next commit will enable it for qapi/, but not for qga/
and tests/.  Making it work for the latter two would involve some Meson
hackery to ensure we generate the trace-events files before trace-tool
uses them.  Since we don't actually support tracing there, we'll bypass
that problem.

4e86df1732 qapi/gen: Add FOO.trace-events output module
We are going to generate trace events for QMP commands. We should
generate both trace_*() function calls and trace-events files listing
events for trace generator.

So, add an output module FOO.trace-events for each FOO schema module.

Since we're going to add trace events only to command marshallers,
make the trace-events output optional, so we don't generate so many
useless empty files.

Currently nobody set add_trace_events to True, so new functionality is
disabled. It will be enabled for QAPISchemaGenCommandVisitor
in a further commit.

64631f3681 block: drop BLK_PERM_GRAPH_MOD
First, this permission never protected a node from being changed, as
generic child-replacing functions don't check it.

Second, it's a strange thing: it presents a permission of parent node
to change its child. But generally, children are replaced by different
mechanisms, like jobs or qmp commands, not by nodes.

Graph-mod permission is hard to understand. All other permissions
describe operations which done by parent node on its child: read,
write, resize. Graph modification operations are something completely
different.

The only place where BLK_PERM_GRAPH_MOD is used as "perm" (not shared
perm) is mirror_start_job, for s->target. Still modern code should use
bdrv_freeze_backing_chain() to protect from graph modification, if we
don't do it somewhere it may be considered as a bug. So, it's a bit
risky to drop GRAPH_MOD, and analyzing of possible loss of protection
is hard. But one day we should do it, let's do it now.

One more bit of information is that locking the corresponding byte in
file-posix doesn't make sense at all.

a5730b8bd3 block/file-posix: Simplify the XFS_IOC_DIOINFO handling
The handling for the XFS_IOC_DIOINFO ioctl is currently quite excessive:
This is not a "real" feature like the other features that we provide with
the "--enable-xxx" and "--disable-xxx" switches for the configure script,
since this does not influence lots of code (it's only about one call to
xfsctl() in file-posix.c), so people don't gain much with the ability to
disable this with "--disable-xfsctl".
It's also unfortunate that the ioctl will be disabled on Linux in case
the user did not install the right xfsprogs-devel package before running
configure. Thus let's simplify this by providing the ioctl definition
on our own, so we can completely get rid of the header dependency and
thus the related code in the configure script.

3d2f73ef75 build: use "meson test" as the test harness
"meson test" starting with version 0.57 is just as capable and easy to
use as QEMU's own TAP driver.  All existing options for "make check"
work.  The only required code change involves how to mark "slow" tests;
they need to belong to an additional "slow" suite.

The rules for .tap output are replaced by JUnit XML; GitLab is able
to parse that output and present it in the CI pipeline report.

142ca628a7 ui: add a D-Bus display backend
The "dbus" display backend exports the QEMU consoles and other
UI-related interfaces over D-Bus.

By default, the connection is established on the session bus, but you
can specify a different bus with the "addr" option.

The backend takes the "org.qemu" service name, while still allowing
further instances to queue on the same name (so you can lookup all the
available instances too). It accepts any number of clients at this
point, although this is expected to evolve with options to restrict
clients, or only accept p2p via fd passing.

The interface is intentionally very close to the internal QEMU API,
and can be introspected or interacted with busctl/dfeet etc:

$ ./qemu-system-x86_64 -name MyVM -display dbus
$ busctl --user introspect org.qemu /org/qemu/Display1/Console_0

206439cd89 scripts/device-crash-test: Use a QMP timeout
Despite all the previous fixes, it's still possible for
device-crash-test to wedge itself in the case that QEMU terminates *so
quickly* that it doesn't even begin a connection attempt to our QMP
client. Python will just joyfully wait ad infinitum for a connection
that will now never arrive.

The real fix is to use asyncio to simultaneously poll both the health of
the launched process AND the connection attempt. That's quite a bit more
invasive than just setting a connection timeout, though.

Do the very simplest thing for now.

This reverts commit ca89d15f8e.

There is already an entry for this kind of messages earlier in the
ERROR_RULE_LIST - when I added this patch, I just got fooled by
the other errors that occur due to a race between QMP connection
and QEMU terminating early (which still spit out the 'No bus found'
messages in their backtrace), but these other problems have now
fortunately been tackled by John Snow, so we certainly don't need
this duplicated entry here anymore.

We don't need to handle KeyboardInterruptError specifically; we can
instead tighten the scope of the broad Exception handlers to only catch
"Exception", which has the effect of allowing all BaseException classes
that do not inherit from Exception to be raised through.

KeyboardInterruptError and a few other important ones are
BaseExceptions, so this does the same thing with less code.

d7c2e2b3f4 Jobs based on custom runners: add CentOS Stream 8
This introduces three different parts of a job designed to run
on a custom runner managed by Red Hat.  The goals include:

  a) propose a model for other organizations that want to onboard
     their own runners, with their specific platforms, build
     configuration and tests.

  b) bring awareness to the differences between upstream QEMU and the
     version available under CentOS Stream, which is "A preview of
     upcoming Red Hat Enterprise Linux minor and major releases".

  c) because of b), it should be easier to identify and reduce the gap
     between Red Hat's downstream and upstream QEMU.

The components of this custom job are:

  I) OS build environment setup code:

     - additions to the existing "build-environment.yml" playbook
       that can be used to set up CentOS/EL 8 systems.

     - a CentOS Stream 8 specific "build-environment.yml" playbook
       that adds to the generic one.

 II) QEMU build configuration: a script that will produce binaries with
     features as similar as possible to the ones built and packaged on
     CentOS stream 8.

III) Scripts that define the minimum amount of testing that the
     binaries built with the given configuration (point II) under the
     given OS build environment (point I) should be subjected to.

 IV) Job definition: GitLab CI jobs that will dispatch the build/test
     jobs (see points #II and #III) to the machine specifically
     configured according to #I.

3d212b41e9 nbd/server: Add --selinux-label option
Under SELinux, Unix domain sockets have two labels.  One is on the
disk and can be set with commands such as chcon(1).  There is a
different label stored in memory (called the process label).  This can
only be set by the process creating the socket.  When using SELinux +
SVirt and wanting qemu to be able to connect to a qemu-nbd instance,
you must set both labels correctly first.

For qemu-nbd the options to set the second label are awkward.  You can
create the socket in a wrapper program and then exec into qemu-nbd.
Or you could try something with LD_PRELOAD.

This commit adds the ability to set the label straightforwardly on the
command line, via the new --selinux-label flag.  (The name of the flag
is the same as the equivalent nbdkit option.)

A worked example showing how to use the new option can be found in
this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1984938

Note that we may relax some of these restrictions at a later date,
such as making it possible to label a TCP socket, although it may be
smarter to do so as a generic QMP action rather than more one-off
command lines in qemu-nbd.

6638cae5f6 meson: bump submodule to 0.59.3
This gains some bugfixes, especially:

- it fixes the introspection of array options.  While technically we
still support Meson 0.58.2, this issue only appears when adding a new
option and not if the user is just building QEMU.  In the relatively
rare case of a contributor using --meson to point to a 0.58 version,
review can catch spurious changes to scripts/meson-buildoptions.sh
easily.

- it fixes "meson test" when it is not the process group leader.  Make is
the process group leader when "make check" invokes "meson test", so this
is a requirement for using it as a test harness.

thereof relying on a QMP Exception type. If you'd like to check for
yourself, you want to grep for all of the derivatives of QMPError,
excluding 'AQMPError' and its derivatives. That'd be these:

- QMPError
- QMPConnectError
- QMPCapabilitiesError
- QMPTimeoutError
- QMPProtocolError
- QMPResponseError
- QMPBadPortError

57df0dff1a qapi: Extend -compat to set policy for unstable interfaces
New option parameters unstable-input and unstable-output set policy
for unstable interfaces just like deprecated-input and
deprecated-output set policy for deprecated interfaces (see commit
6dd75472d5 "qemu-options: New -compat to set policy for deprecated
interfaces").  This is intended for testing users of the management
interfaces.  It is experimental.

For now, this covers only syntactic aspects of QMP, i.e. stuff tagged
with feature 'unstable'.  We may want to extend it to cover semantic
aspects, or the command line.

Note that there is no good way for management application to detect
presence of these new option parameters: they are not visible output
of query-qmp-schema or query-command-line-options.  Tolerable, because
it's meant for testing.  If running with -compat fails, skip the test.

c868876043 qapi: Generalize enum member policy checking
The code to check enumeration value policy can see special feature
flag 'deprecated' in QEnumLookup member flags[value].  I want to make
feature flag 'unstable' visible there as well, so I can add policy for
it.

Instead of extending flags[], replace it by @special_features (a
bitset of QapiSpecialFeature), because that's how special features get
passed around elsewhere.

6604e4757a qapi: Generalize command policy checking
The code to check command policy can see special feature flag
'deprecated' as command flag QCO_DEPRECATED.  I want to make feature
flag 'unstable' visible there as well, so I can add policy for it.

To let me make it visible, add member @special_features (a bitset of
QapiSpecialFeature) to QmpCommand, and adjust the generator to pass it
through qmp_register_command().  Then replace "QCO_DEPRECATED in
@flags" by QAPI_DEPRECATED in @special_features", and drop
QCO_DEPRECATED.

a130728554 qapi: Generalize struct member policy checking
The generated visitor functions call visit_deprecated_accept() and
visit_deprecated() when visiting a struct member with special feature
flag 'deprecated'.  This makes the feature flag visible to the actual
visitors.  I want to make feature flag 'unstable' visible there as
well, so I can add policy for it.

To let me make it visible, replace these functions by
visit_policy_reject() and visit_policy_skip(), which take the member's
special features as an argument.  Note that the new functions have the
opposite sense, i.e. the return value flips.

c67db1ed16 qapi: Tools for sets of special feature flags in generated code
New enum QapiSpecialFeature enumerates the special feature flags.

New helper gen_special_features() returns code to represent a
collection of special feature flags as a bitset.

The next few commits will put them to use.
