8ff58b05a3 migration/rdma: Clean up two more harmless signed vs. unsigned issues
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.

25352b371b migration/rdma: Fix unwanted integer truncation
qio_channel_rdma_readv() assigns the size_t value of qemu_rdma_fill()

@want, both size_t.  Truncation when qemu_rdma_fill() copies more than
INT_MAX bytes.  Seems vanishingly unlikely, but needs fixing all the
same.

b5631d5bda migration/rdma: Drop fragile wr_id formatting
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.

0e99bb8f54 migration: Allow RECOVER->PAUSED convertion for dest qemu
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.

4111a732e8 migration: Set migration status early in incoming side
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.

28fa97e006 tests/qtest: migration: Add migrate_incoming_qmp helper
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.

48de646280 target/arm: Move the reference to arm-core.xml
Some subclasses overwrite gdb_core_xml_file member but others don't.
Always initialize the member in the subclasses for consistency.

This especially helps for AArch64; in a following change, the file
specified by gdb_core_xml_file is always looked up even if it's going to
be overwritten later. Looking up arm-core.xml results in an error as
it will not be embedded in the AArch64 build.

1063693e1c contrib/plugins: Use GRWLock in execlog
execlog had the following comment:
> As we could have multiple threads trying to do this we need to
> serialise the expansion under a lock. Threads accessing already
> created entries can continue without issue even if the ptr array
> gets reallocated during resize.

However, when the ptr array gets reallocated, the other threads may have
a stale reference to the old buffer. This results in use-after-free.

Use GRWLock to properly fix this issue.

c691925092 tests/docker: make docker engine choice entirely configure driven
Since 0b1a649047 (tests/docker: use direct RUNC call to build
containers) we ended up with the potential for the remaining docker.py
script calls to deviate from the direct RUNC calls. Fix this by
dropping the use of ENGINE in the makefile and rely entirely on what
we detect at configure time.

We also tweak the RUNC detection so podman users can still run things
from the source tree.

We move a couple of targets out of the avocado runs because there are
no tests to run. Tricore already has some coverage.  The cris target
only really has check-tcg tests but its getting harder to find
anything that packages the compiler.

To reduce the noise of CANCEL messages we also set AVOCADO_TAGS
appropriately so we filter down the number of tests we attempt.

stable:

   env QEMU_TEST_FLAKY_TESTS=1 retry.py -n 50 -c -- \
     ./tests/venv/bin/avocado run \
     ./tests/avocado/machine_aarch64_sbsaref.py:Aarch64SbsarefMachine.test_sbsaref_edk2_firmware

yields:

  Results summary:

  Ran command 50 times, 50 passes

Maybe f0ec14c78c (tests/avocado: Fix console data loss) has made it
