Previous to this patch the only way CVQ would be shadowed is if it does
support to isolate CVQ group or if all vqs were shadowed from the
beginning. The second condition was checked at the beginning, and no
more configuration was done.
After this series we need to check if data queues are shadowed because
they are in the middle of the migration. As checking if they are
shadowed already covers the previous case, let's just mimic it.

The vhost-vdpa net backend needs to enable vrings in a different order
than default, so export it.
No functional change intended except for tracing, that now includes the
(virtio) index being enabled and the return value of the ioctl.
Still ignoring return value of this function if called from
vhost_vdpa_dev_start, as reorganize calling code around it is out of
the scope of this series.

Doing that way allows CVQ to be enabled before the dataplane vqs,
restoring the state as MQ or MAC addresses properly in the case of a
migration.
The patch does it by defining a ->load NetClientInfo callback also for
dataplane. Ideally, this should be done by an independent patch, but
the function is already static so it would only add an empty
vhost_vdpa_net_data_load stub.

Subject: Fix x86 machine type compatibility for qemu-kvm 8.1.0
Jira: https://issues.redhat.com/browse/RHEL-874
Upstream Status: RHEL-only
Upstream changes pcmc->default_smbios_ep_type in the -8.0 machine
type, so we should reflect this change in our -rhel9.2.0 machine
types (and older).
While we're at it, add a comment that the pcmc->enforce_amd_1tb_hole
setting comes from pc_i440fx_7_0_machine_options() in pc_piix.c.

RH-Jira: RHEL-7360

RH-Commit: [2/5] d853b88d6b71b6f4fe1bb70ae2e3b6108cbdb8dc (hreitz/qemu-kvm-c-9-s)
Instead of checking bs->wps or bs->bl.zone_size for whether zone
information is present, check bs->bl.zoned. That is the flag that
raw_refresh_zoned_limits() reliably sets to indicate zone support. If
it is set to something other than BLK_Z_NONE, other values and objects
like bs->wps and bs->bl.zone_size must be non-null/zero and valid; if it
is not, we cannot rely on their validity.

(cherry picked from commit 4b5d80f3d02096a9bb1f651f6b3401ba40877159)
Downstream: Fixed typo in the last hunk ("bs->blk" changed to
"bs->blk"). This code is removed in the commit after the
next, still, should be fixed now that I noticed.

bs->bl.zoned is what indicates whether the zone information is present
and valid; it is the only thing that raw_refresh_zoned_limits() sets if
CONFIG_BLKZONED is not defined, and it is also the only thing that it
sets if CONFIG_BLKZONED is defined, but there are no zones.
Make sure that it is always set to BLK_Z_NONE if there is an error
anywhere in raw_refresh_zoned_limits() so that we do not accidentally
announce zones while our information is incomplete or invalid.
This also fixes a memory leak in the last error path in
raw_refresh_zoned_limits().

We'll start calling the await_return_path_close_on_source() function
from other parts of the code, so move all of the related checks and
tracepoints into it.

We don't need to set the rp_state.error right after a shutdown because
qemu_file_shutdown() always sets the QEMUFile error, so the return
path thread would have seen it and set the rp error itself.
Setting the error outside of the thread is also racy because the
thread could clear it after we set it.

It's not safe to call qemu_file_shutdown() on the to_dst_file without
first checking for the file's presence under the lock. The cleanup of
this file happens at postcopy_pause() and migrate_fd_cleanup() which
are not necessarily running in the same thread as migrate_fd_cancel().

We cannot call qemu_file_shutdown() on the return path file without
taking the file lock. The return path thread could be running it's
cleanup code and have just cleared the from_dst_file pointer.
Checking ms->to_dst_file for errors could also race with
migrate_fd_cleanup() which clears the to_dst_file pointer.
Protect both accesses by taking the file lock.
This was caught by inspection, it should be rare, but the next patches
will start calling this code from other places, so let's do the
correct thing.

RH-Commit: [1/8] a1197ca99878d5d8bbb271c6941aa36d91c66122 (peterx/qemu-kvm)
We hit intermit CI issue on failing at migration-test over the unit test
preempt/plain:
qemu-system-x86_64: Unable to read from socket: Connection reset by peer
Memory content inconsistency at 5b43000 first_byte = bd last_byte = bc current = 4f hit_edge = 1
**
ERROR:../tests/qtest/migration-test.c:300:check_guests_ram: assertion failed: (bad == 0)
(test program exited with status code -6)
Fabiano debugged into it and found that the preempt thread can quit even
without receiving all the pages, which can cause guest not receiving all
the pages and corrupt the guest memory.
To make sure preempt thread finished receiving all the pages, we can rely
on the page_requested_count being zero because preempt channel will only
receive requested page faults. Note, not all the faulted pages are required
to be sent via the preempt channel/thread; imagine the case when a
requested page is just queued into the background main channel for
migration, the src qemu will just still send it via the background channel.
Here instead of spinning over reading the count, we add a condvar so the
main thread can wait on it if that unusual case happened, without burning
the cpu for no good reason, even if the duration is short; so even if we
spin in this rare case is probably fine. It's just better to not do so.
The condvar is only used when that special case is triggered. Some memory
ordering trick is needed to guarantee it from happening (against the
preempt thread status field), so the main thread will always get a kick
when that triggers correctly.

RH-Commit: [7/8] 6b9d9b955f95ff14b47491865e7e45bfdcfc8a97 (peterx/qemu-kvm)
Replace the return path retry logic with finishing and restarting the
thread. This fixes a race when resuming the migration that leads to a
segfault.
Currently when doing postcopy we consider that an IO error on the
return path file could be due to a network intermittency. We then keep
the thread alive but have it do cleanup of the 'from_dst_file' and
wait on the 'postcopy_pause_rp' semaphore. When the user issues a
migrate resume, a new return path is opened and the thread is allowed
to continue.
There's a race condition in the above mechanism. It is possible for
the new return path file to be setup *before* the cleanup code in the
return path thread has had a chance to run, leading to the *new* file
being closed and the pointer set to NULL. When the thread is released
after the resume, it tries to dereference 'from_dst_file' and crashes:
Thread 7 "return path" received signal SIGSEGV, Segmentation fault.

Here's the race (important bit is open_return_path happening before
migration_release_dst_files):
migration | qmp | return path
--------------------------+-----------------------------+---------------------------------
qmp_migrate_pause()
shutdown(ms->to_dst_file)
f->last_error = -EIO
migrate_detect_error()
postcopy_pause()
set_state(PAUSED)
wait(postcopy_pause_sem)
qmp_migrate(resume)
migrate_fd_connect()
resume = state == PAUSED
open_return_path <-- TOO SOON!
set_state(RECOVER)
post(postcopy_pause_sem)
(incoming closes to_src_file)
res = qemu_file_get_error(rp)
migration_release_dst_files()
ms->rp_state.from_dst_file = NULL
post(postcopy_pause_rp_sem)
postcopy_pause_return_path_thread()
wait(postcopy_pause_rp_sem)
rp = ms->rp_state.from_dst_file
goto retry
qemu_file_get_error(rp)
SIGSEGV
-------------------------------------------------------------------------------------------
We can keep the retry logic without having the thread alive and
waiting. The only piece of data used by it is the 'from_dst_file' and
it is only allowed to proceed after a migrate resume is issued and the
semaphore released at migrate_fd_connect().
Move the retry logic to outside the thread by waiting for the thread
to finish before pausing the migration.

This is a regression test for
https://bugzilla.redhat.com/show_bug.cgi?id=2234374.
All this test needs to do is trigger an I/O error inside of file-posix
(specifically raw_co_prw()). One reliable way to do this without
requiring special privileges is to use a FUSE export, which allows us to
inject any error that we want, e.g. via blkdebug.

RH-Author: Kevin Wolf <kwolf@redhat.com>
RH-MergeRequest: 201: virtio: Drop out of coroutine context in virtio_load()
RH-Jira: RHEL-832
RH-Acked-by: Hanna Czenczek <hreitz@redhat.com>

RH-Commit: [1/1] 64ca84cf9bd82eb9e22a1840909e99958ceb51a6 (kmwolf/centos-qemu-kvm)
virtio_load() as a whole should run in coroutine context because it
reads from the migration stream and we don't want this to block.
However, it calls virtio_set_features_nocheck() and devices don't
expect their .set_features callback to run in a coroutine and therefore
call functions that may not be called in coroutine context. To fix this,
drop out of coroutine context for calling virtio_set_features_nocheck().
