qemu_rdma_exchange_get_response() compares int parameter @expecting
with uint32_t head->type. Actual arguments are non-negative
enumeration constants, RDMAControlHeader uint32_t member type, or
qemu_rdma_exchange_recv() int parameter expecting. Actual arguments
for the latter are non-negative enumeration constants. Change both
parameters to uint32_t.
In qio_channel_rdma_readv(), loop control variable @i is ssize_t, and
counts from 0 up to @niov, which is size_t. Change @i to size_t.
While there, make qio_channel_rdma_readv() and
qio_channel_rdma_writev() more consistent: change the former's @done
to ssize_t, and delete the latter's useless initialization of @len.

qio_channel_rdma_readv() assigns the size_t value of qemu_rdma_fill()
to an int variable before it adds it to @done / subtracts it from
@want, both size_t. Truncation when qemu_rdma_fill() copies more than
INT_MAX bytes. Seems vanishingly unlikely, but needs fixing all the
same.

We use int instead of uint64_t in a few places. Change them to
uint64_t.
This cleans up a comparison of signed qemu_rdma_block_for_wrid()
parameter @wrid_requested with unsigned @wr_id. Harmless, because the
actual arguments are non-negative enumeration constants.

wrid_desc[] uses 4001 pointers to map four integer values to strings.
print_wrid() accesses wrid_desc[] out of bounds when passed a negative
argument. It returns null for values 2..1999 and 2001..3999.
qemu_rdma_poll() and qemu_rdma_block_for_wrid() print wrid_desc[wr_id]
and passes print_wrid(wr_id) to tracepoints. Could conceivably crash
trying to format a null string. I believe access out of bounds is not
possible.
Not worth cleaning up. Dumb down to show just numeric wr_id.

There's a bug on dest that if a double fault triggered on dest qemu (a
network issue during postcopy-recover), we won't set PAUSED correctly
because we assumed we always came from ACTIVE.
Fix that by always overwriting the state to PAUSE.
We could also check for these two states, but maybe it's an overkill. We
did the same on the src QEMU to unconditionally switch to PAUSE anyway.

We are sending a migration event of MIGRATION_STATUS_SETUP at
qemu_start_incoming_migration but never actually setting the state.
This creates a window between qmp_migrate_incoming and
process_incoming_migration_co where the migration status is still
MIGRATION_STATUS_NONE. Calling query-migrate during this time will
return an empty response even though the incoming migration command
has already been issued.
Commit 7cf1fe6d68 ("migration: Add migration events on target side")
has added support to the 'events' capability to the incoming part of
migration, but chose to send the SETUP event without setting the
state. I'm assuming this was a mistake.
This introduces a change in behavior, any QMP client waiting for the
SETUP event will hang, unless it has previously enabled the 'events'
capability. Having the capability enabled is sufficient to continue to
receive the event.

file-based migration requires the target to initiate its migration after
the source has finished writing out the data in the file. Currently
there's no easy way to initiate 'migrate-incoming', allow this by
introducing migrate_incoming_qmp helper, similarly to migrate_qmp.
Also make sure migration events are enabled and wait for the incoming
migration to start before returning. This avoid a race when querying
the migration status too soon after issuing the command.

Currently query-dirty-rate uses QEMU_CLOCK_REALTIME as
the source for start-time field. This translates to
clock_gettime(CLOCK_MONOTONIC), i.e. number of seconds
since host boot. This is not very useful. The only
reasonable use case of start-time I can imagine is to
check whether previously completed measurements are
too old or not. But this makes sense only if start-time
is reported as host wall-clock time.
This patch replaces source of start-time from
QEMU_CLOCK_REALTIME to QEMU_CLOCK_HOST.

Default audio devices can now be created with "-audio". Tests for
soundcards were already using "-audiodev" if they want to specify a
particular backend, for the others remove the last remnants of
legacy audio configuration.

Make VNC use the default backend again if one is defined.
The recently introduced support for disabling the VNC audio
extension is still used, in case no default backend exists.

It is now possible to specify the options for the default audio device
using -audio, so there is no need anymore to use a fake -audiodev option.
Remove the fall back to QTAILQ_FIRST(&audio_states), instead remember the
AudioState that was created from default_audiodevs and use that one.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
If "-audio BACKEND" is used without a model, the resulting backend
will be used whenever the audiodev property is not specified.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Match what is done for other options, for example -monitor, and also
the behavior of QEMU 8.1 (see the "legacy_config" variable). Require
the user to specify a backend if one is specified on the command line.

Setting --bindir= to an absolute path that is shorter than the
prefix causes GCC to complain about array accesses out of bounds.
The code however is safe, so disable the warning and explain why
we are doing so.

"softmmu" is a deprecated moniker, do the easy change matching
the variable to the command line option.

The softmmu/ directory contains files specific to system
emulation. Rename it as system/. Update meson rules, the
MAINTAINERS file and all the documentation and comments.

Finish the convertion started with commit de6cd7599b
("meson: Replace softmmu_ss -> system_ss"). If the
$target_type is 'system', then use the target_system_arch[]
source set :)
Mechanical change doing:
$ sed -i -e s/target_softmmu_arch/target_system_arch/g \
$(git grep -l target_softmmu_arch)

Software MMU is TCG specific. Here 'softmmu' is misused
for system emulation. Anyhow, since KVM is system emulation
specific, just rename as 'i386_kvm_ss'.

Add a check in 'softmmu-uaccess.h' that the header is only
include in system emulation, and rename it as 'uaccess.h'.
Rename the API methods:
- softmmu_[un]lock_user*() -> uaccess_[un]lock_user*()
- softmmu_strlen_user() -> uaccess_strlen_user().
Update a pair of comments.
