handle_qmp_command() reports certain errors right away. This is wrong
when OOB is enabled, because the errors can "jump the queue" then, as
the previous commit demonstrates.
To fix, we need to delay errors until dispatch. Do that for semantic
errors, mostly by reverting ill-advised parts of commit cf869d5317
"qmp: support out-of-band (oob) execution". Bonus: doesn't run
qmp_dispatch_check_obj() twice, once in handle_qmp_command(), and
again in do_qmp_dispatch(). That's also due to commit cf869d5317.
The next commit will fix queue jumping for syntax errors.

When OOB is enabled, out-of-band commands are executed right away,
everything else is queued. This lets out-of-band commands "jump the
queue".
However, certain errors are always reported right away, and therefore
can jump the queue even when the erroneous input does not request
out-of-band execution. These errors are pretty unlikely to occur in
production, but it's wrong all the same. Mark FIXME.

Commit cf869d5317 "qmp: support out-of-band (oob) execution" added a
general mechanism for command-independent arguments just for an
out-of-band flag:
The "control" key is introduced to store this extra flag. "control"
field is used to store arguments that are shared by all the commands,
rather than command specific arguments. Let "run-oob" be the first.
However, it failed to reject unknown members of "control". For
instance, in QMP command
{"execute": "query-name", "id": 42, "control": {"crap": true}}
"crap" gets silently ignored.
Instead of fixing this, revert the general "control" mechanism
(because YAGNI), and do it the way I initially proposed, with key
"exec-oob". Simpler code, simpler interface.
An out-of-band command
{"execute": "migrate-pause", "id": 42, "control": {"run-oob": true}}
becomes
{"exec-oob": "migrate-pause", "id": 42}

[Commit message typo fixed]
Commit cf869d5317 "qmp: support out-of-band (oob) execution"
accidentally made qemu-ga accept and ignore "control". Fix that.
Out-of-band execution in a monitor that doesn't support it now fails
with
{"error": {"class": "GenericError", "desc": "QMP input member 'control' is unexpected"}}
instead of
{"error": {"class": "GenericError", "desc": "Please enable out-of-band first for the session during capabilities negotiation"}}
The old description is suboptimal when out-of-band cannot not be
enabled, or the command doesn't support out-of-band execution.
The new description is a bit unspecific, but it'll do.

tests/qmp-test tests an out-of-band command overtaking a slow in-band
command. To do that, it needs:
1. An in-band command that *reliably* takes long enough to be
overtaken.
2. An out-of-band command to do the overtaking.
3. To avoid delays, a way to make the in-band command complete quickly
after it was overtaken.
To satisfy these needs, commit 469638f9cb provides the rather
peculiar oob-capable QMP command x-oob-test:
* With "lock": true, it waits for a global semaphore.
* With "lock": false, it signals the global semaphore.
To satisfy 1., the test runs x-oob-test in-band with "lock": true.
To satisfy 2. and 3., it runs x-oob-test out-of-band with "lock": false.
Note that waiting for a semaphore violates the rules for oob-capable
commands. Running x-oob-test with "lock": true hangs the monitor
until you run x-oob-test with "lock": false on another monitor (which
you might not have set up).
Having an externally visible QMP command that may hang the monitor is
not nice. Let's apply a little more ingenuity to the problem. Idea:
have an existing command block on reading a FIFO special file, unblock
it by opening the FIFO for writing.
For 1., use
{"execute": "blockdev-add", "id": ID1,
"arguments": {
"driver": "blkdebug", "node-name": ID1, "config": FIFO,
"image": { "driver": "null-co"}}}
where ID1 is an arbitrary string, and FIFO is the name of the FIFO.
For 2., use
{"execute": "migrate-pause", "id": ID2, "control": {"run-oob": true}}
where ID2 is a different arbitrary string. Since there's no migration
to pause, the command will fail, but that's fine; instant failure is
still a test of out-of-band responses overtaking in-band commands.
For 3., open FIFO for writing.
Drop QMP command x-oob-test.

Pre-Shared Keys (PSK) is a simpler mechanism for enabling TLS
connections than using certificates. It requires only a simple secret
key:
$ mkdir -m 0700 /tmp/keys
$ psktool -u rjones -p /tmp/keys/keys.psk
$ cat /tmp/keys/keys.psk
rjones:d543770c15ad93d76443fb56f501a31969235f47e999720ae8d2336f6a13fcbc
The key can be secretly shared between clients and servers. Clients
must specify the directory containing the "keys.psk" file and a
username (defaults to "qemu"). Servers must specify only the
directory.
Example NBD client:
$ qemu-img info \
--object tls-creds-psk,id=tls0,dir=/tmp/keys,username=rjones,endpoint=client \
--image-opts \
file.driver=nbd,file.host=localhost,file.port=10809,file.tls-creds=tls0,file.export=/
Example NBD server using qemu-nbd:
$ qemu-nbd -t -x / \
--object tls-creds-psk,id=tls0,endpoint=server,dir=/tmp/keys \
--tls-creds tls0 \

Although this test is NOT a full test of image fleecing (as it
intentionally uses just a single block device directly exported
over NBD, rather than trying to set up a blockdev-backup job with
multiple BDS involved), it DOES prove that qemu as a server is
able to properly expose a dirty bitmap over NBD.
When coupled with image fleecing, it is then possible for a
third-party client to do an incremental backup by using
qemu-img map with the x-dirty-bitmap option to learn which parts
of the file are dirty (perhaps confusingly, they are the portions
mapped as "data":false - which is part of the reason this is
still in the x- experimental namespace), along with another
normal client (perhaps 'qemu-nbd -c' to expose the server over
/dev/nbd0 and then just use normal I/O on that block device) to
read the dirty sections.

There are two useful macros that can be defined before including
glib.h that are related to the min required glib version
- GLIB_VERSION_MIN_REQUIRED
When this is defined, if code uses an API that was deprecated
in this version, or older, a compiler warning will be emitted.
This alerts maintainers to update their code to whatever new
replacement API is now recommended best practice.
- GLIB_VERSION_MAX_ALLOWED
When this is defined, if code uses an API that was introduced
in a version that is newer than the declared version, a compiler
warning will be emitted. This alerts maintainers if new code
accidentally uses functionality that won't be available on some
supported platforms.
The GLIB_VERSION_MAX_ALLOWED constant makes it a bit harder to opt
in to using specific new APIs with a GLIB_CHECK_VERSION conditional.
To workaround this Pragmas can be used to temporarily turn off the
-Wdeprecated-declarations compiler warning, while a static inline
compat function is implemented. This workaround is illustrated with the
implementation of the g_strv_contains method to satisfy the test suite.

Per supported platforms doc[1], the various min glib on relevant distros is:
RHEL-7: 2.50.3
Debian (Stretch): 2.50.3
Debian (Jessie): 2.42.1
OpenBSD (Ports): 2.54.3
FreeBSD (Ports): 2.50.3
OpenSUSE Leap 15: 2.54.3
SLE12-SP2: 2.48.2
Ubuntu (Xenial): 2.48.0
macOS (Homebrew): 2.56.0
This suggests that a minimum glib of 2.42 is a reasonable target.
The GLibC compile farm, however, uses Ubuntu 14.04 (Trusty) which only
has glib 2.40.0, and this is needed for testing during merge. Thus an
exception is made to the documented platform support policy to allow for
all three current LTS releases to be supported.
Docker jobs that not longer satisfy this new min version are removed.

Peter reported that the boot-serial tester sometimes runs into timeouts
with SPARC guests. It's currently completely unclear whether this is due
to too much load on the host machine (so that the guest really just ran
too slow), or whether there is something wrong with the guest's firmware
boot. For further debugging, we need the serial output of the guest in
case of errors, so instead of unlinking the file immediately, this is
now only done in case of success. In case of error, print the name of the
file with the serial output via g_error() (which then also calls abort()
internally to mark the test as failed).

The "I" bit in PIO Setup and D2H FISes is exclusively a device concept
and the irqstatus register in the controller does not matter. The SATA
spec says when it should be one; for D2H FISes in practice it is always
set, while the PIO Setup FIS has several subcases that are documented in
the patch.
Also, the PIO Setup FIS interrupt is actually generated _after_ data
has been received.
Someone should probably spend some time reading the SATA specification and
figuring out the more obscure fields in the PIO Setup FIS, but this is enough
to fix SeaBIOS booting from ATAPI CD-ROMs over an AHCI controller.

It often happens that just a few discriminator values imply extra data in
a flat union. Existing checks did not make possible to leave other values
uncovered. Such cases had to be worked around by either stating a dummy
(empty) type or introducing another (subset) discriminator enumeration.
Both options create redundant entities in qapi files for little profit.
With this patch it is not necessary anymore to add designated union
fields for every possible value of a discriminator enumeration.

the first step to making better cross-architecture testing available
straight from the source tree ;-)

Commit 0bcc8e5b was yet another instance of 'git status' reporting
dirty files after an in-tree build, thanks to the new binary
tests/check-block-qdict.
Instead of piecemeal exemptions of each new binary as they are
added, let's use git's negative globbing feature to exempt ALL
files that have a 'test-' or 'check-' prefix, except for the ones
ending in '.c' or '.sh'. We still have a couple of generated
files that then need (re-)exclusion, but the overall list is a
LOT shorter, and less prone to needing future edits.

it is "old".

As we now ensure all the images we are going to use are built in the
top level make file lets not over complicate things by running the
full script again. We do run the check script just in case someone
deletes the docker image while we are running.

This command allows you to check if we need to re-build a docker
image. If the image isn't in the repository or the checksums don't
match then we return false and some text (for processing in
makefiles).
Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
This just gets confusing especially as the helper function doesn't
even take into account any extra files (or the executable). Currently
the actual check just ignores them and also passes the result through
_dockerfile_preprocess so we fix that too.

The "images" command is a fairly heavyweight command to run as it
involves searching the whole docker file-system inventory. On a
machine with a lot of images this makes start-up fairly expensive.

One problem with satisfying your docker dependencies in a sub-make it
you might end up trying to satisfy the dependency multiple times. This
is especially a problem with debian-sid based cross compilers and CI
setups. We solve this by doing a docker build pass at the top level
before any sub-makes are called.
We still need to satisfy dependencies in the Makefile.target call so
people can run tests from individual target directories. We introduce
a new Makefile.probe which gets called for each PROBE_TARGET and
allows us to build up the list. It does require multiply including
config-target.mak which shouldn't cause any issues as it shouldn't
define anything that clashes with config-host.mak. However we undefine
a few key variables each time around.
