2d00cbd8e2 block/qcow2-bitmap: use bdrv_dirty_bitmap_next_dirty
store_bitmap_data() loop does bdrv_set_dirty_iter() on each iteration,
which means that we actually don't need iterator itself and we can use
simpler bitmap API.

dacbb6eb8a nbd/server: use bdrv_dirty_bitmap_next_dirty_area
Use bdrv_dirty_bitmap_next_dirty_area for bitmap_to_extents. Since
bdrv_dirty_bitmap_next_dirty_area is very accurate in its interface,
we'll never exceed requested region with last chunk. So, we don't need
dont_fragment, and bitmap_to_extents() interface becomes clean enough
to not require any comment.

299ea9ff01 block/dirty-bitmap: improve _next_dirty_area API
Firstly, _next_dirty_area is for scenarios when we may contiguously
search for next dirty area inside some limited region, so it is more
comfortable to specify "end" which should not be recalculated on each
iteration.

Secondly, let's add a possibility to limit resulting area size, not
limiting searching area. This will be used in NBD code in further
commit. (Note that now bdrv_dirty_bitmap_next_dirty_area is unused)

642700fda0 block/dirty-bitmap: switch _next_dirty_area and _next_zero to int64_t
We are going to introduce bdrv_dirty_bitmap_next_dirty so that same
variable may be used to store its return value and to be its parameter,
so it would int64_t.

Similarly, we are going to refactor hbitmap_next_dirty_area to use
hbitmap_next_dirty together with hbitmap_next_zero, therefore we want
hbitmap_next_zero parameter type to be int64_t too.

So, for convenience update all parameters of *_next_zero and
*_next_dirty_area to be int64_t.

Therefore we can't handle bitmaps with absolute size larger than

safer.

Note, that bitmaps are used to represent disk images, which can't
exceed INT64_MAX anyway.

781c67ca55 cpu: Use DeviceClass reset instead of a special CPUClass reset
The CPUClass has a 'reset' method.  This is a legacy from when
TYPE_CPU used not to inherit from TYPE_DEVICE.  We don't need it any
more, as we can simply use the TYPE_DEVICE reset.  The 'cpu_reset()'
function is kept as the API which most places use to reset a CPU; it
is now a wrapper which calls device_cold_reset() and then the
tracepoint function.

This change should not cause CPU objects to be reset more often
than they are at the moment, because:
 * nobody is directly calling device_cold_reset() or
   qdev_reset_all() on CPU objects
 * no CPU object is on a qbus, so they will not be reset either
   by somebody calling qbus_reset_all()/bus_cold_reset(), or
   by the main "reset sysbus and everything in the qbus tree"
   reset that most devices are reset by

Note that this does not change the need for each machine or whatever
to use qemu_register_reset() to arrange to call cpu_reset() -- that
is necessary because CPU objects are not on any qbus, so they don't
get reset when the qbus tree rooted at the sysbus bus is reset, and
this isn't being changed here.

All the changes to the files under target/ were made using the
included Coccinelle script, except:

(1) the deletion of the now-inaccurate and not terribly useful
"CPUClass::reset" comments was done with a perl one-liner afterwards:
  perl -n -i -e '/ CPUClass::reset/ or print' target/*/*.c

(2) this bit of the s390 change was done by hand, because the
Coccinelle script is not sophisticated enough to handle the
parent_reset call being inside another function:

| @@ -96,8 +96,9 @@ static void s390_cpu_reset(CPUState *s, cpu_reset_type type)
|     S390CPU *cpu = S390_CPU(s);

a51d6a5493 tests/docker: make "buildah bud" output similar to "docker build"
Podman users will most often be using buildah to build containers.
Among the differences between "buildah bud|build-using-dockerfile" and
a traditional "docker build" is that buildah does not run a container
during build.

To the best of my knowledge and experiments, this means that runtime
variables, such as ENV from one base image will not propagate into
another.  The end result is that the location for the cross compiler
binaries, defined in the base "qemu/debian9-mxe" image, are not passed
through this image.  Consequently, the cross compilers are not on PATH
and the build fails.

4ec49f0fcd Acceptance tests: add make targets to download images
The newly introduced "boot linux" tests make use of Linux images that
are larger than usual, and fall into what Avocado calls "vmimages",
and can be referred to by name, version and architecture.

The images can be downloaded automatically during the test. But, to
make for more reliable test results, this introduces a target that
will download the vmimages for the architectures that have been
configured and are available for the currently used distro (Fedora
31).

6fd52d671d Acceptance test: add "boot_linux" tests
This acceptance test, validates that a full blown Linux guest can
successfully boot in QEMU.  In this specific case, the guest chosen is
Fedora version 31.

 * x86_64, pc-i440fx and pc-q35 machine types, with TCG and KVM as
   accelerators

 * aarch64 and virt machine type, with TCG and KVM as accelerators

 * ppc64 and pseries machine type with TCG as accelerator

 * s390x and s390-ccw-virtio machine type with TCG as accelerator

The Avocado vmimage utils library is used to download and cache the
Linux guest images, and from those images a snapshot image is created
and given to QEMU.  If a qemu-img binary is available in the build
directory, it's used to create the snapshot image, so that matching
qemu-system-* and qemu-img are used in the same test run.  If qemu-img
is not available in the build tree, one is attempted to be found
installed system-wide (in the $PATH).  If qemu-img is not found in the
build dir or in the $PATH, the test is canceled.

The method for checking the successful boot is based on "cloudinit"
and its "phone home" feature.  The guest is given an ISO image with
the location of the phone home server, and the information to post
(the instance ID).  Upon receiving the correct information, from the
guest, the test is considered to have PASSed.

This test is currently limited to user mode networking only, and
instructs the guest to connect to the "router" address that is hard
coded in QEMU.

To create the cloudinit ISO image that will be used to configure the
guest, the pycdlib library is also required and has been added as
requirement to the virtual environment created by "check-venv".

The console output is read by a separate thread, by means of the
Avocado datadrainer utility module.

b44513b13d Acceptance tests: introduce BUILD_DIR and SOURCE_DIR
Some tests may benefit from using resources from a build directory.
This introduces three variables that can help tests find resources in
those directories.

First, a BUILD_DIR is assumed to exist, given that the primary form of
running the acceptance tests is from a build directory (which may or
may not be the same as the source tree, that is, the SOURCE_DIR).

If the directory containing the acceptance tests happens to be a link
to a directory, it's assumed to it points to the source tree
(SOURCE_DIR), which is the behavior defined on the QEMU Makefiles.  If
the directory containing the acceptance tests is not a link, then a
in-tree build is assumed, and the BUILD_DIR and SOURCE_DIR have the
same value.

08712fcb85 net: Track netdevs in NetClientState rather than QemuOpt
As mentioned in the previous patch, our use of QemuOpt group "netdev"
has two purposes: collect the CLI arguments, and serve as a witness
for monitor hotplug actions.  As the latter didn't use anything but an
id, it felt rather unclean to have to touch QemuOpts at all when going
through QMP, so let's instead track things with a bool field in
NetClientState.

db2a380c84 net: Complete qapi-fication of netdev_add
We've had all the required pieces for doing a type-safe representation
of netdev_add as a flat union for quite some time now (since
0e55c381f6 in v2.7.0, released in 2016), but did not make the final
switch to using it because of concern about whether a command-line
regression in accepting "1" in place of 1 for integer arguments would
be problematic.  Back then, we did not have the deprecation cycle to
allow us to make progress.  But now that we have waited so long, other
problems have crept in: for example, our desire to add
qemu-storage-daemon is hampered by the inability to express net
objects, and we are unable to introspect what we actually accept.
Additionally, our round-trip through QemuOpts silently eats any
argument that expands to an array, rendering dnssearch, hostfwd, and
guestfwd useless through QMP:

{"execute": "netdev_add", "arguments": { "id": "netdev0",
  "type": "user", "dnssearch": [
    { "str": "8.8.8.8" }, { "str": "8.8.4.4" }
  ]}}

So without further ado, let's turn on proper QAPI.  netdev_add() was a
trivial wrapper around net_client_init(), which did a few steps prior
to calling net_client_init1(); with this patch, we now skip directly
to net_client_init1().  In addition to fixing array parameters, the
following additional differences occur:

-  {"execute": "netdev_add", "arguments": {"type": "help"}}
no longer attempts to print help to stdout and exit.  Bug fix, broken
in 547203ead4 'net: List available netdevs with "-netdev help"',
v2.12.0.

-  {"execute": "netdev_add", "arguments': {... "ipv6-net": "..." }}
no longer attempts to desugar the undocumented ipv6-net magic string
into the proper "ipv6-prefix" and "ipv6-prefixlen".  Undocumented
misfeature, introduced in commit 7aac531ef2 "qapi-schema, qemu-options
& slirp: Adding Qemu options for IPv6 addresses", v2.6.0.

-  {'execute':'netdev_add',
     'arguments':{'id':'net2', 'type':'hubport', 'hubid':"2"}}
   {"error": {"class": "GenericError", "desc": "Invalid parameter type for 'hubid', expected: integer"}}
Used to succeed: since our command line treats everything as strings,
our not-so-round-trip conversion from QAPI -> QemuOpts -> QAPI lost
the original typing and turned everything into a string; now that we
skip the QemuOpts, the JSON input has to match the exact QAPI type.
But this stricter QMP is desirable, and introspection is sufficient
for any affected applications to make sure they use it correctly.

In qmp_netdev_add(), we still have to create a QemuOpts object so that
qmp_netdev_del() will be able to remove a hotplugged network device;
but the opts->head remains empty since we now manage all parsing
through the QAPI object rather than QemuOpts; a separate patch will
address the abuse of QemuOpts as a witness for whether a
NetClientState is a netdev.  In the meantime, our argument that we are
okay requires auditing all uses of option group "netdev":

- qemu_netdev_opts: option group definition, empty .desc[]
- CLI (CLI netdev parsing ends before monitors start, so while
  monitors can mess with CLI netdevs, CLI cannot mess with
  monitor netdevs):
  - main() case QEMU_OPTION_netdev: store CLI definition
  - main() case QEMU_OPTION_readconfig, case QEMU_OPTION_writeconfig:
  similar, dealing only with CLI
  - net_init_clients(): Pass CLI to net_client_init()
- Monitor:
  - hmp_netdev_add(): straightforward parse into net_client_init()
  - qmp_netdev_add(): subject of this patch, used to add full
  object to option group, now just adds bare-bones id
  - qmp_netdev_del(), netdev_del_completion(): check the option group
  solely for id, as a 'is this a netdev' predicate

df4097aeaf qapi: Mark deprecated QMP parts with feature 'deprecated'
Add feature 'deprecated' to the deprecated QMP commands, so their
deprecation becomes visible in output of query-qmp-schema.  Looks like
this:

    {"name": "query-cpus",
     "ret-type": "[164]",
     "meta-type": "command",
     "arg-type": "0",
---> "features": ["deprecated"]}

Management applications could conceivably use this for static
checking.

The deprecated commands are change, cpu-add, migrate-set-cache-size,
migrate_set_downtime, migrate_set_speed, query-cpus, query-events,
query-migrate-cache-size.

The deprecated command arguments are block-commit arguments @base and
@top, and block_set_io_throttle, blockdev-change-medium,
blockdev-close-tray, blockdev-open-tray, eject argument @device.

The deprecated command results are query-cpus-fast result @arch,
query-block result @dirty-bitmaps, query-named-block-nodes result
@encryption_key_missing and result @dirty-bitmaps's member @status.
Same for query-block result @inserted, which mirrors
query-named-block-nodes.
