Telling QTest to log to /dev/fd/2, essentially results in dup(2). This
is fine, if other code isn't logging to stderr. Otherwise, the order of
the logs is mixed due to buffering issues, since two file-descriptors
are used to write to the same file. We can avoid this, since just
specifying "-qtest" sets the log fd to stderr. If we want to disable
qtest logs, we can just add -qtest-log none.

The previous, already existing 'basic' readdir test simply used a
'count' parameter big enough to retrieve all directory entries with a
single Treaddir request.
In the 3 new 'split' readdir tests added by this patch, directory
entries are retrieved, split over several Treaddir requests by picking
small 'count' parameters which force the server to truncate the
response. So the test client sends as many Treaddir requests as
necessary to get all directory entries.
The following 3 new tests are added (executed in this sequence):
1. Split readdir test with count=512
2. Split readdir test with count=256
3. Split readdir test with count=128
This test case sequence is chosen because the smaller the 'count' value,
the higher the chance of errors in case of implementation bugs on server
side.

In the initial FuzzTarget, get_init_cmdline returned a char *. With this
API, we had no guarantee about where the string came from. For example,
i440fx-qtest-reboot-fuzz simply returned a pointer to a string literal,
while the QOS-based targets build the arguments out in a GString an
return the gchar *str pointer. Since we did not try to free the cmdline,
we have a leak for any targets that do not simply return string
literals. Clean up this mess by forcing fuzz-targets to return
a GString, that we can free.

Total execution time with "-m slow" and x86_64 QEMU, drops from 3
minutes 15 seconds, down to 54 seconds.
Individual tests drop from 17-20 seconds, down to 3-4 seconds.
The cost of this change is that any QOM bugs resulting in the test
failure will not be directly associated with the device that caused
the failure. The test case is not frequently identifying such bugs
though, and the cause is likely easily visible in the patch series
that causes the failure. So overall the shorter running time is
considered the more important factor.

The qtest_enabled check introduced in d6919e4 always returns false, as
it is called prior to configure_accelerators(). Instead of trying to
skip rcu_disable_atfork in qemu_main, simply call rcu_enable_atfork in
the fuzzer, after qemu_main returns.

This reverts commit 6d1da867e6 ("tests/migration: Reduce autoconverge initial bandwidth")
since that change makes unit tests much slower for all developers, while it's not
a robust way to fix migration tests. Migration tests need to find
a more robust way to discover a reasonable bandwidth without slowing
things down for everyone.

QEMU incorrectly validates FEAT_SVM feature flags against
GET_SUPPORTED_CPUID even if SVM features are being masked out by
cpu_x86_cpuid(). This can make QEMU print warnings on most AMD
CPU models, even when SVM nesting is disabled (which is the
default).
This bug was never detected before because of a Linux KVM bug:
until Linux v5.6, KVM was not filtering out SVM features in
GET_SUPPORTED_CPUID when nested was disabled. This KVM bug was
fixed in Linux v5.7-rc1, on Linux commit a50718cc3f43 ("KVM:
nSVM: Expose SVM features to L1 iff nested is enabled").
Fix the problem by adding a CPUID_EXT3_SVM dependency to all
FEAT_SVM feature flags in the feature_dependencies table.

bios-tables-test executes SeaBIOS. Indeed FW is needed to
fetch tables from QEMU and put them into the guest RAM. Also
the FW patches cross table pointers. At some point, SeaBIOS
ends up calling the TPM2_CC_HierarchyControl command with
TPM2_ST_SESSIONS tag, most probably steming from
tpm_set_failure/tpm20_hierarchycontrol SeaBIOS call path.
This causes an assert() in the qtest tpm emulation code.
As the goal here is not to boot SeaBIOS completely but just
let it grab the ACPI tables and consolidate them, let's just
remove the assert().

The fuzzers are built into a binary (e.g. qemu-fuzz-i386). To select the
device to fuzz/fuzz target, we usually use the --fuzz-target= argument.
This commit allows the fuzz-target to be specified using the name of the
executable. If the executable name ends with -target-FUZZ_TARGET, then
we select the fuzz target based on this name, rather than the
--fuzz-target argument. This is useful for systems such as oss-fuzz
where we don't have control of the arguments passed to the fuzzer.

As per ACPI spec 6.3, Table 19-419 Object Conversion Rules, if
the Buffer Field <= to the size of an Integer (in bits), it will
be treated as an integer. Moreover, the integer size depends on
DSDT tables revision number. If revision number is < 2, integer
size is 32 bits, otherwise it is 64 bits. Current NVDIMM common
DSM aml code (NCAL) uses CreateField() for creating DSM output
buffer. This creates an issue in arm/virt platform where DSDT
revision number is 2 and results in DSM buffer with a wrong
size(8 bytes) gets returned when actual length is < 8 bytes.
This causes guest kernel to report,
"nfit ACPI0012:00: found a zero length table '0' parsing nfit"
In order to fix this, aml code is now modified such that it builds
the DSM output buffer in a byte by byte fashion when length is
smaller than Integer size.

apply_to_qlist(), apply_to_node() work with QObjects. This is
designed for use by tests/qtest/qos-test.c, which gets the data in
that form via QMP. Goes back to commit fc281c8020 "tests: qgraph API
for the qtest driver framework".
Commit 275ab39d86 "fuzz: add support for qos-assisted fuzz targets"
added another user: qtest/fuzz/qos_fuzz.c. To get the data as
QObjects, it uses qmp_marshal_query_machines() and
qmp_marshal_qom_list_types().
All this code is rather cumbersome. Switch to working with generated
QAPI types instead:
* Replace apply_to_qlist() & friends by machines_apply_to_node() and
types_apply_to_node().
* Have qos_fuzz.c use qmp_query_machines() and qmp_qom_list_types()
instead.
* Have qos_test.c convert from QObject to the QAPI types.

With QEMU 4.0 an incompatible change was added to pc_piix, which makes it
practical impossible to migrate domUs started with qemu2 or qemu3 to
newer qemu versions. Commit 7fccf2a068
added and enabled a new member "smbus_no_migration_support". In commit
4ab2f2a8aa the vmstate_acpi got new
elements, which are conditionally filled. As a result, an incoming
migration expected smbus related data unless smbus migration was
disabled for a given MachineClass. Since first commit forgot to handle
'xenfv', domUs started with QEMU 4.x are incompatible with their QEMU
siblings.
Using other existing machine types, such as 'pc-i440fx-3.1', is not
possible because 'xenfv' creates the 'xen-platform' PCI device at
00:02.0, while all other variants to run a domU would create it at
00:04.0.
To cover both the existing and the broken case of 'xenfv' in a single
qemu binary, a new compatibility variant of 'xenfv-4.2' must be added
which targets domUs started with qemu 4.2. The existing 'xenfv' restores
compatibility of QEMU 5.x with qemu 3.1.
Host admins who started domUs with QEMU 4.x (preferrable QEMU 4.2)
have to use a wrapper script which appends '-machine xenfv-4.2' to
the device-model command line. This is only required if there is no
maintenance window which allows to temporary shutdown the domU and
restart it with a fixed device-model.
The wrapper script is as simple as this:
#!/bin/sh
exec /usr/bin/qemu-system-i386 "$@" -machine xenfv-4.2
With xl this script will be enabled with device_model_override=, see
xl.cfg(5). To live migrate a domU, adjust the existing domU.cfg and pass
it to xl migrate or xl save/restore:
xl migrate -C new-domU.cfg domU remote-host
xl save domU CheckpointFile new-domU.cfg
xl restore new-domU.cfg CheckpointFile
With libvirt this script will be enabled with the <emulator> element in
domU.xml. Use 'virsh edit' prior 'virsh migrate' to replace the existing
<emulator> element to point it to the wrapper script.

The tulip networking card emulation has an OOB issue in
'tulip_copy_tx_buffers' when the guest provide malformed descriptor.
This test will trigger a ASAN heap overflow crash. To trigger this
issue we can construct the data as following:
1. construct a 'tulip_descriptor'. Its control is set to
'0x7ff | 0x7ff << 11', this will make the 'tulip_copy_tx_buffers's
'len1' and 'len2' to 0x7ff(2047). So 'len1+len2' will overflow
'TULIPState's 'tx_frame' field. This descriptor's 'buf_addr1' and
'buf_addr2' should set to a guest address.
2. write this descriptor to tulip device's CSR4 register. This will
set the 'TULIPState's 'current_tx_desc' field.
3. write 'CSR6_ST' to tulip device's CSR6 register. This will trigger
'tulip_xmit_list_update' and finally calls 'tulip_copy_tx_buffers'.
Following shows the backtrack of crash:

Per David Gilbert, "it could just be the writing is slow on s390

Tuning the threshold by reducing the initial bandwidth makes the

Description copied from Linux kernel commit from Gustavo A. R. Silva
(see [3]):
--v-- description start --v--
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to
declare variable-length types such as these ones is a flexible
array member [1], introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler
warning in case the flexible array does not occur last in the
structure, which will help us prevent some kind of undefined
behavior bugs from being unadvertenly introduced [2] to the
Linux codebase from now on.
--^-- description end --^--
Do the similar housekeeping in the QEMU codebase (which uses
C99 since commit 7be41675f7).

ISA and sysbus TPM-TIS devices will share their tests. Only
the main() will change (instantiation option is different).
Also the base address of the TPM-TIS device is going to be
different. on x86 it is located at 0xFED40000 while on ARM
it can be located at any location, discovered through the
device tree description.
So we put shared test functions in a new object module.
Each test needs to set tpm_tis_base_addr global variable.
Also take benefit of this move to fix "block comments using
a leading */ on a separate line" checkpatch warnings.

This series removes ad hoc RAM allocation API (memory_region_allocate_system_memory)
and consolidates it around hostmem backend. It allows to
* resolve conflicts between global -mem-prealloc and hostmem's "policy" option,
fixing premature allocation before binding policy is applied
* simplify complicated memory allocation routines which had to deal with 2 ways
to allocate RAM.
* reuse hostmem backends of a choice for main RAM without adding extra CLI
options to duplicate hostmem features. A recent case was -mem-shared, to
enable vhost-user on targets that don't support hostmem backends [1] (ex: s390)
* move RAM allocation from individual boards into generic machine code and
provide them with prepared MemoryRegion.
* clean up deprecated NUMA features which were tied to the old API (see patches)
- "numa: remove deprecated -mem-path fallback to anonymous RAM"
- (POSTPONED, waiting on libvirt side) "forbid '-numa node,mem' for 5.0 and newer machine types"
- (POSTPONED) "numa: remove deprecated implicit RAM distribution between nodes"
Introduce a new machine.memory-backend property and wrapper code that aliases
global -mem-path and -mem-alloc into automatically created hostmem backend
properties (provided memory-backend was not set explicitly given by user).
A bulk of trivial patches then follow to incrementally convert individual
boards to using machine.memory-backend provided MemoryRegion.
Board conversion typically involves:
* providing MachineClass::default_ram_size and MachineClass::default_ram_id
so generic code could create default backend if user didn't explicitly provide
memory-backend or -m options
* dropping memory_region_allocate_system_memory() call
* using convenience MachineState::ram MemoryRegion, which points to MemoryRegion
allocated by ram-memdev
On top of that for some boards:
* missing ram_size checks are added (typically it were boards with fixed ram size)
* ram_size fixups are replaced by checks and hard errors, forcing user to
provide correct "-m" values instead of ignoring it and continuing running.
After all boards are converted, the old API is removed and memory allocation
routines are cleaned up.

fork() is a simple way to ensure that state does not leak in between
fuzzing runs. Unfortunately, the fuzzer mutation engine relies on
bitmaps which contain coverage information for each fuzzing run, and
these bitmaps should be copied from the child to the parent(where the
mutation occurs). These bitmaps are created through compile-time
instrumentation and they are not shared with fork()-ed processes, by
default. To address this, we create a shared memory region, adjust its
size and map it _over_ the counter region. Furthermore, libfuzzer
doesn't generally expose the globals that specify the location of the
counters/coverage bitmap. As a workaround, we rely on a custom linker
script which forces all of the bitmaps we care about to be placed in a
contiguous region, which is easy to locate and mmap over.

There's an assert in autoconverge that checks that we quit the

saw a case where this assert fired with the measured value
slightly over the threshold. (about 3k out of a few million).
I can think of two reasons:
a) Rounding errors
b) That after we make the decision to quit iteration we do one
more sync and that sees a few more dirty pages.
So add 1% slack to the assertion, that should cover a and

Commit e51e711b1b has moved the initialization of start_address and
end_address after the definition of the command line argument,
where the nvramrc is initialized, and thus the loop is between 0 and 0
rather than 1 MiB and 100 MiB.
It doesn't affect the result of the test if all the tests are run in
sequence because the two first tests don't run the loop, so the
values are correctly initialized when we actually need them.
But it hangs when we ask to run only one test, for instance:
QTEST_QEMU_BINARY=ppc64-softmmu/qemu-system-ppc64 \
tests/migration-test -m=quick -p /ppc64/migration/validate_uuid_error
Fixes: e51e711b1b ("tests/migration: Add migration-test header file")

The qos stuff belongs to qtest, so move it into that directory, too.

tests/Makefile.include is pretty much overcrowded. Now that we have a
dedicated folder for the qtests, let's move the related settings
to a Makefile.include file in that directory instead.

The tests directory itself is pretty overcrowded, and it's hard to
see which test belongs to which test subsystem (unit, qtest, ...).
Let's move the qtests to a separate folder for more clarity.
