When the frontend device has no space for a read the fd is removed
from polling to allow time for the guest to read and clear the buffer.
Without the call to qemu_chr_fe_accept_input(), the poll will not be
broken out of when the guest has cleared the buffer causing significant
IO delays that get worse with smaller buffers.

size_to_str() can return a size like "4.24 MiB", with a single digit
integer part and two fractional digits. This is eight characters, but
commit b39847a5 changed the format string to only reserve seven
characters for the column.
This can result in unaligned columns, which in turn changes the output of
iotests case 267 because exceeding the column size defeats the attempt
to filter the size out of the output (observed with the ppc64 emulator).
The resulting change is only a whitespace change, but since commit
f203080b this is enough for iotests to consider the test failed.
Taking a character away from the tag name column and adding it to the VM
size column doesn't change anything in the common case (the tag name is
left justified, the VM size is right justified), but fixes this case.

For -makecheck, the old 'check' implementation skipped the output when
starting a test. It only had the condensed output at the end of a test.
testrunner.py prints the normal output when starting a test even for
-makecheck. This output contains '\r' at the end so that it can be
overwritten with the result at the end of the test. However, for
-makecheck this is shorter output in a different format, so effectively
we end up with garbled output that mixes both output forms.
Revert to the old behaviour of only printing a message after the test
had completed in -makecheck mode.

If the qemu-system-{arch} binary for the host architecture can't be
found, the old 'check' implementation selected the alphabetically first
system emulator binary that it could find. The new Python implementation
just uses the first result of glob.iglob(), which has an undefined
order.
This is a problem that breaks CI because the iotests aren't actually
prepared to run on any emulator. They should be, so this is really a bug
in the failing test cases that should be fixed there, but as a quick
fix, let's revert to the old behaviour to let CI runs succeed again.

Doubling-processing of a BDS is especially problematic for the

I also have plans of moving other block-jobs onto block-copy, so that
we finally have one generic block copying path, fast and well-formed.
So, now I suggest to bring all parts of backup architecture into
"Block Jobs" subsystem (actually, aio_task is shared with qcow2 and
qemu-co-shared-resource can be reused somewhere else, but I'd keep an
eye on them in context of block-jobs) and add myself as co-maintainer.

There is currently no way to open(O_RDONLY) and mmap(PROT_READ) when
creating a memory region from a file. This functionality is needed since
the underlying host file may not allow writing.
Add a bool readonly argument to memory_region_init_ram_from_file() and
the APIs it calls.
Extend memory_region_init_ram_from_file() rather than introducing a
memory_region_init_rom_from_file() API so that callers can easily make a
choice between read/write and read-only at runtime without calling
different APIs.
No new RAMBlock flag is introduced for read-only because it's unclear
whether RAMBlocks need to know that they are read-only. Pass a bool
readonly argument instead.
Both of these design decisions can be changed in the future. It just
seemed like the simplest approach to me.

vhost_vdpa_set_config(void *dev, uint32_t offset, uint32_t size, \
uint32_t flags) "dev: %p offset: %"PRIu32" \
size: %"PRIu32" flags: 0x%"PRIx32
generates:
printf("%d@%d vhost_vdpa_set_config dev: %p offset: %u size: %u \
flags: 0x%u\n", pid(), gettimeofday_ns(), dev, offset, \
size, flags)
for the "flags" parameter, we can see a "0x%u" rather than a "0x%x"
because the first macro was "PRIu32" (for offset).
In the loop, macro becomes "PRIu32PRIu32PRIx32", and c_macro_to_format()
returns always macro[3] ('u' in this case). This patch resets macro after
the format has been decoded.

Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.
This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.
The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.
The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

The distinction between short life and long life Linux distributions
turned out to be redundant. They can both be covered in a simple way
by noting support will target the current release, and the previous
release for a period of two years or until its EOL. This rule can also
apply to the other UNIX based distros, leaving only Windows needing a
different set of rules.
This also clarifies that Debian LTS is out of scope, because the LTS
support is provided by a separate group from the main Debian maintainer
team.

The -enable-fips option was added a long time ago to prevent the use of
single DES when VNC when FIPS mode is enabled. It should never have been
added, because apps are supposed to unconditionally honour FIPS mode
based on the '/proc/sys/crypto/fips_enabled' file contents.
In addition there is more to achieving FIPS compliance than merely
blocking use of certain algorithms. Those algorithms which are used
need to perform self-tests at runtime.
QEMU's built-in cryptography provider has no support for self-tests,
and neither does the nettle library.
If QEMU is required to be used in a FIPS enabled host, then it must be
built with the libgcrypt library enabled, which will unconditionally
enforce FIPS compliance in any algorithm usage.
Thus there is no need to keep either the -enable-fips option in QEMU, or
QEMU's internal FIPS checking methods.

If you set the loaded property to true when it was already true, the
state is overwritten without freeing the old state first. Change the
set_loaded callback so that it always frees the old state (which is a
no-op if nothing was loaded) and only then load if requestsd.

qcrypto_secret_prop_set_loaded() forgets to reset secret->rawdata after
unloading a secret, which will lead to a double free at some point.
Because there is no use case for unloading an already loaded secret
(apart from deleting the whole secret object) and we know that nobody
could use this because it would lead to crashes, let's just forbid the
operation instead of fixing the unloading.
Eventually, we'll want to get rid of 'loaded' in the external interface,
but for the meantime this is more consistent with rng, which has a
similar property 'opened' that also can't be reset to false after it
became true.
