722d8e73d6 block: Avoid processing BDS twice in bdrv_set_aio_context_ignore()
Some graphs may contain an indirect reference to the first BDS in the
chain that can be reached while walking it bottom->up from one its
children.

Doubling-processing of a BDS is especially problematic for the
aio_notifiers, as they might attempt to work on both the old and the
new AIO contexts.

To avoid this problem, add every child and parent to the ignore list
before actually processing them.

Vladimir Sementsov-Ogievskiy
d7beddcc02 MAINTAINERS: Add Vladimir as co-maintainer for Block Jobs
I'm developing Qemu backup for several years, and finally new backup
architecture, including block-copy generic engine and backup-top filter
landed upstream, great thanks to reviewers and especially to
Max Reitz!

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.

86635aa4e9 hostmem-file: add readonly=on|off option
Let -object memory-backend-file work on read-only files when the
readonly=on option is given. This can be used to share the contents of a
file between multiple guests while preventing them from consuming
Copy-on-Write memory if guests dirty the pages, for example.

369d6dc4de memory: add readonly support to memory_region_init_ram_from_file()
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.

0dfb3ca73c trace: update docs with meson build information
The documentation still refers to the makefile and the old sub-directory
layout. Meson works differently: tracetool output is placed into the
builddir with mangled filenames like <builddir>/trace/trace-accel_kvm.h
for the accel/kvm/ trace.h definition.

This meson setup also requires a manually-created accel/kvm/trace.h file
that #includes the <builddir>/trace/trace-accel_kvm.h file. Document
this!

651d588f03 error: rename error_with_timestamp to message_with_timestamp
The -msg timestamp=on|off option controls whether a timestamp is printed
with error_report() messages. The "-msg" name suggests that this option
has a wider effect than just error_report(). The next patch extends it
to the 'log' trace backend, so rename the variable from
error_with_timestamp to message_with_timestamp.

9f4e519fd7 tracetool: fix "PRI" macro decoding
macro is not reset after use, so the format decoded is always the
one of the first "PRI" in the format string.

For instance:

  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.

7d7dbf9dc1 configure: replace --enable/disable-git-update with --with-git-submodules
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.

e6e80fcfd6 docs: simplify and clarify the platform support rules
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.

166310299a os: deprecate the -enable-fips option and QEMU's FIPS enforcement
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.

668cb74b2a crypto: Forbid broken unloading of secrets
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.

eeae0b2bf4 hw/watchdog/cmsdk-apb-watchdog: Add Clock input
As the first step in converting the CMSDK_APB_TIMER device to the
Clock framework, add a Clock input.  For the moment we do nothing
with this clock; we will change the behaviour from using the
wdogclk-frq property to using the Clock once all the users of this
device have been converted to wire up the Clock.

This is a migration compatibility break for machines mps2-an385,
mps2-an386, mps2-an500, mps2-an511, mps2-an505, mps2-an521, musca-a,
musca-b1, lm3s811evb, lm3s6965evb.

55fd0f84a2 hw/timer/cmsdk-apb-dualtimer: Add Clock input
As the first step in converting the CMSDK_APB_DUALTIMER device to the
Clock framework, add a Clock input.  For the moment we do nothing
with this clock; we will change the behaviour from using the pclk-frq
property to using the Clock once all the users of this device have
been converted to wire up the Clock.

We take the opportunity to correct the name of the clock input to
match the hardware -- the dual timer names the clock which drives the
timers TIMCLK.  (It does also have a 'pclk' input, which is used only
for the register and APB bus logic; on the SSE-200 these clocks are
both connected together.)

mps2-an386, mps2-an500, mps2-an511, mps2-an505, mps2-an521, musca-a,
musca-b1.
