Michael S. Tsirkin dc03272da6 qga: use local path for local headers
When pulling in headers that are in the same directory as the C file (as
opposed to one in include/), we should use its relative path, without a
directory.

Marc-André Lureau cb3e7f08ae qobject: Replace qobject_incref/QINCREF qobject_decref/QDECREF
Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.

The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked().  Unlike
qobject_decref(), qobject_unref() doesn't accept void *.

Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

Max Reitz 7dc847ebba qapi: Replace qobject_to_X(o) by qobject_to(X, o)

Thomas Huth 7e563bfb8a Polish the version strings containing the package version
Since commit 67a1de0d19 there is no space anymore between the
version number and the parentheses when running configure with
--with-pkgversion=foo :

 $ qemu-system-s390x --version
 QEMU emulator version 2.11.50(foo)

But the space is included when building without that option
when building from a git checkout:

 $ qemu-system-s390x --version
 QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty)

The same confusion exists with the "query-version" QMP command.
Let's fix this by introducing a proper QEMU_FULL_VERSION definition
that includes the space and parentheses, while the QEMU_PKGVERSION
should just cleanly contain the package version string itself.
Note that this also changes the behavior of the "query-version" QMP
command (the space and parentheses are not included there anymore),
but that's supposed to be OK since the strings there are not meant
to be parsed by other tools.

basename(3) and dirname(3) modify their argument and may return
pointers to statically allocated memory which may be overwritten by
subsequent calls.
g_path_get_basename and g_path_get_dirname have no such issues, and
therefore more preferable.

Markus Armbruster eb815e248f qapi: Move qapi-schema.json to qapi/, rename generated files
Move qapi-schema.json to qapi/, so it's next to its modules, and all

Consistently name the generated files qapi-MODULE.EXT:
qmp-commands.[ch] become qapi-commands.[ch], qapi-event.[ch] become
qapi-events.[ch], and qmp-introspect.[ch] become qapi-introspect.[ch].

Daniel P. Berrange 62473511ec sockets: remove obsolete code that updated listen address
When listening on unix/tcp sockets there was optional code that would update
the original SocketAddress struct with the info about the actual address that
was listened on. Since the conversion of everything to QIOChannelSocket, no
remaining caller made use of this feature. It has been replaced with the ability
to query the listen address after the fact using the function
qio_channel_socket_get_local_address. This is a better model when the input
address can result in listening on multiple distinct sockets.

Eric Blake f5048cb751 maint: Include bug-reporting info in --help output
These days, many programs are including a bug-reporting address,
or better yet, a link to the project web site, at the tail of
their --help output.  However, we were not very consistent at
doing so: only qemu-nbd and qemu-qa mentioned anything, with the
latter pointing to an individual person instead of the project.

Add a new #define that sets up a uniform string, mentioning both
bug reporting instructions and overall project details, and which
a downstream vendor could tweak if they want bugs to go to a
downstream database.  Then use it in all of our binaries which
have --help output.

The canned text intentionally references http:// instead of https://
because our https website currently causes certificate errors in
some browsers.  That can be tweaked later once we have resolved the
web site issued.

Markus Armbruster bd269ebc82 sockets: Limit SocketAddressLegacy to external interfaces
SocketAddressLegacy is a simple union, and simple unions are awkward:
they have their variant members wrapped in a "data" object on the
wire, and require additional indirections in C.  SocketAddress is the
equivalent flat union.  Convert all users of SocketAddressLegacy to
SocketAddress, except for existing external interfaces.

See also commit fce5d53..9445673 and 85a82e8..c5f1ae3.

Markus Armbruster dfd100f242 sockets: Rename SocketAddress to SocketAddressLegacy
The next commit will rename SocketAddressFlat to SocketAddress, and
the commit after that will replace most uses of SocketAddressLegacy by
SocketAddress, replacing most of this commit's renames right back.

Note that checkpatch emits a few "line over 80 characters" warnings.
The long lines are all temporary; the SocketAddressLegacy replacement
will shorten them again.

Adds a new command `guest-get-timezone` reporting the currently
configured timezone on the system. The information on what timezone is
currently is configured is useful in case of Windows VMs where the
offset of the hardware clock is required to have the same offset. This
can be used for management systems like `oVirt` to detect the timezone
difference and warn administrators of the misconfiguration.

Sameeh Jubran 94d81ae896 qga-win: Fix a bug where qemu-ga service is stuck during stop operation
After triggering a freeze command without any following thaw command,
qemu-ga will not respond to stop operation. This behaviour is wanted on Linux
as there is no time limit for a freeze command and we want to prevent
quitting in the middle of freeze, on the other hand on Windows the time
limit for freeze is 10 seconds, so we should wait for the timeout, thaw
the file system and quit.

@can-offline: Whether offlining the VCPU is possible. This member
               is always filled in by the guest agent when the structure
               is returned, and always ignored on input (hence it can be

Currently 'can-offline' is missing entirely from the reply. This causes
errors in libvirt which is expecting the reply to be compliant with the
schema docs.

Michael Roth 8251a72f8b qga: don't fail if mount doesn't have slave devices
In some cases the slave devices of a virtual block device are tracked
by the parent in the corresponding sysfs node. For instance, if we
have a loop-back mount of the form:

  /dev/loop3p1 on /home/mdroth/mnt type ext4 (rw,relatime,data=ordered)

this will be reflected in sysfs as:

  /sys/devices/virtual/block/loop3/
  ...
  /sys/devices/virtual/block/loop3/slaves
  /sys/devices/virtual/block/loop3/loop3p1

The current code however assumes the mounted virtual block device,
loop3p1 in this case, contains the slaves directory, and reports an
error otherwise. This breaks 'make check' in certain environments.

Fix this by simply skipping attempts to generate disk topology
information in these cases. Since this information is documented
in QAPI as optionally-reported, this should be ok from an API
perspective.

In the future, this can possibly be improved upon by collecting
topology information from the parent in these cases.

Paolo Bonzini 53fabd4b86 qemu-ga: obey LISTEN_PID when using systemd socket activation
qemu-ga's socket activation support was not obeying the LISTEN_PID
environment variable, which avoids that a process uses a socket-activation
file descriptor meant for its parent.

Mess can for example ensue if a process forks a children before consuming
the socket-activation file descriptor and therefore setting O_CLOEXEC
on it.

Luckily, qemu-nbd also got socket activation code, and its copy does
support LISTEN_PID.  Some extra fixups are needed to ensure that the
code can be used for both, but that's what this patch does.  The
main change is to replace get_listen_fds's "consume" argument with
the FIRST_SOCKET_ACTIVATION_FD macro from the qemu-nbd code.

Markus Armbruster 1d8bda128d qapi: The #optional tag is redundant, drop
We traditionally mark optional members #optional in the doc comment.
Before commit 3313b61, this was entirely manual.

Commit 3313b61 added some automation because its qapi2texi.py relied
on #optional to determine whether a member is optional.  This is no
longer the case since the previous commit: the only thing qapi2texi.py
still does with #optional is stripping it out.  We still reject bogus
qapi-schema.json and six places for qga/qapi-schema.json.

Thus, you can't actually rely on #optional to see whether something is
optional.  Yet we still make people add it manually.  That's just
busy-work.

Drop the code to check, fix up and strip out #optional, along with all
instances of #optional.  To keep it out, add code to reject it, to be
dropped again once the dust settles.

No change to generated documentation.

Markus Armbruster bc52d03ff5 qapi: Make doc comments optional where we don't need them
Since we added the documentation generator in commit 3313b61, doc
comments are mandatory.  That's a very good idea for a schema that
needs to be documented, but has proven to be annoying for testing.

Make doc comments optional again, but add a new directive

    { 'pragma': { 'doc-required': true } }

to let a QAPI schema require them.

Add test cases for the new pragma directive.  While there, plug a
minor hole in includ directive test coverage.

Require documentation in the schemas we actually want documented:
qapi-schema.json and qga/qapi-schema.json.

We could probably make qapi2texi.py cope with incomplete
documentation, but for now, simply make it refuse to run unless the
schema has 'doc-required': true.
