8af54b9172 machine: remove 'query-cpus' QMP command
The newer 'query-cpus-fast' command avoids side effects on the guest
execution. Note that some of the field names are different in the
'query-cpus-fast' command.

cbde7be900 migrate: remove QMP/HMP commands for speed, downtime and cache size
The generic 'migrate_set_parameters' command handle all types of param.

Only the QMP commands were documented in the deprecations page, but the
rationale for deprecating applies equally to HMP, and the replacements
exist. Furthermore the HMP commands are just shims to the QMP commands,
so removing the latter breaks the former unless they get re-implemented.

8becb36063 monitor: remove 'query-events' QMP command
The code comment suggests removing QAPIEvent_(str|lookup) symbols too,
however, these are both auto-generated as standard for any enum in
QAPI. As such it they'll exist whether we use them or not.

758b96b61d vfio/migrate: Move switch of dirty tracking into vfio_memory_listener
For now the switch of vfio dirty page tracking is integrated into
@vfio_save_handler. The reason is that some PCI vendor driver may
start to track dirty base on _SAVING state of device, so if dirty
tracking is started before setting device state, vfio will report
full-dirty to QEMU.

However, the dirty bmap of all ramblocks are fully set when setup
ram saving, so it's not matter whether the device is in _SAVING
state when start vfio dirty tracking.

Moreover, this logic causes some problems [1]. The object of dirty
tracking is guest memory, but the object of @vfio_save_handler is
device state, which produces unnecessary coupling and conflicts:

1. Coupling: Their saving granule is different (perVM vs perDevice).
   vfio will enable dirty_page_tracking for each devices, actually
   once is enough.

2. Conflicts: The ram_save_setup() traverses all memory_listeners
   to execute their log_start() and log_sync() hooks to get the
   first round dirty bitmap, which is used by the bulk stage of
   ram saving. However, as vfio dirty tracking is not yet started,
   it can't get dirty bitmap from vfio. Then we give up the chance
   to handle vfio dirty page at bulk stage.

Move the switch of vfio dirty_page_tracking into vfio_memory_listener
can solve above problems. Besides, Do not require devices in SAVING
state for vfio_sync_dirty_bitmap().

1eb7f64275 vfio: Support host translation granule size
The cpu_physical_memory_set_dirty_lebitmap() can quickly deal with
the dirty pages of memory by bitmap-traveling, regardless of whether
the bitmap is aligned correctly or not.

cpu_physical_memory_set_dirty_lebitmap() supports pages in bitmap of
host page size. So it'd better to set bitmap_pgsize to host page size
to support more translation granule sizes.

[aw: The Fixes commit below introduced code to restrict migration
support to configurations where the target page size intersects the
host dirty page support.  For example, a 4K guest on a 4K host.
Due to the above flexibility in bitmap handling, this restriction
unnecessarily prevents mixed target/host pages size that could
otherwise be supported.  Use host page size for dirty bitmap.]

ecebe53fe9 vfio: Avoid disabling and enabling vectors repeatedly in VFIO migration
In VFIO migration resume phase and some guest startups, there are
already unmasked vectors in the vector table when calling
vfio_msix_enable(). So in order to avoid inefficiently disabling
and enabling vectors repeatedly, let's allocate all needed vectors
first and then enable these unmasked vectors one by one without
disabling.

8ce1ff990e vfio: Set the priority of the VFIO VM state change handler explicitly
In the VFIO VM state change handler when stopping the VM, the _RUNNING
bit in device_state is cleared which makes the VFIO device stop, including
no longer generating interrupts. Then we can save the pending states of
all interrupts in the GIC VM state change handler (on ARM).

So we have to set the priority of the VFIO VM state change handler
explicitly (like virtio devices) to ensure it is called before the
GIC's in saving.

d329f5032e vfio: Move the saving of the config space to the right place in VFIO migration
On ARM64 the VFIO SET_IRQS ioctl is dependent on the VM interrupt
setup, if the restoring of the VFIO PCI device config space is
before the VGIC, an error might occur in the kernel.

So we move the saving of the config space to the non-iterable
process, thus it will be called after the VGIC according to
their priorities.

As for the possible dependence of the device specific migration
data on it's config space, we can let the vendor driver to
include any config info it needs in its own data stream.

1a8e22bd20 spapr_iommu: Fix vhost integration regression
Previous work on dev-iotlb message broke spapr_iommu/vhost integration
as it did for SMMU and virtio-iommu. The spapr_iommu currently
only sends IOMMU_NOTIFIER_UNMAP notifications. Since commit
958ec334bc ("vhost: Unbreak SMMU and virtio-iommu on dev-iotlb support"),
VHOST first tries to register IOMMU_NOTIFIER_DEVIOTLB_UNMAP notifier
and if it fails, falls back to legacy IOMMU_NOTIFIER_UNMAP. So
spapr_iommu must fail on the IOMMU_NOTIFIER_DEVIOTLB_UNMAP
registration.

8dca037b48 vfio: Do not register any IOMMU_NOTIFIER_DEVIOTLB_UNMAP notifier
In an attempt to fix smmu/virtio-iommu - vhost regression, commit
958ec334bc ("vhost: Unbreak SMMU and virtio-iommu on dev-iotlb support")
broke virtio-iommu integration. This is due to the fact VFIO registers
IOMMU_NOTIFIER_ALL notifiers, which includes IOMMU_NOTIFIER_DEVIOTLB_UNMAP
and this latter now is rejected by the virtio-iommu. As a consequence,
the registration fails. VHOST behaves like a device with an ATC cache. The
VFIO device does not support this scheme yet.

Let's register only legacy MAP and UNMAP notifiers.

20afcc23b3 virtiofsd: Don't allow empty paths in lookup_name()
When passed an empty filename, lookup_name() returns the inode of
the parent directory, unless the parent is the root in which case
the st_dev doesn't match and lo_find() returns NULL. This is
because lookup_name() passes AT_EMPTY_PATH down to fstatat() or
statx().

This behavior doesn't quite make sense because users of lookup_name()
then pass the name to unlinkat(), renameat() or renameat2(), all of
which will always fail on empty names.

Drop AT_EMPTY_PATH from the flags in lookup_name() so that it has
the consistent behavior of "returning an existing child inode or
NULL" for all directories.

28d1ad0ea4 virtiofsd: Don't allow empty filenames
POSIX.1-2017 clearly stipulates that empty filenames aren't
allowed ([1] and [2]). Since virtiofsd is supposed to mirror
the host file system hierarchy and the host can be assumed to
be linux, we don't really expect clients to pass requests with
an empty path in it. If they do so anyway, this would eventually
cause an error when trying to create/lookup the actual inode
on the underlying POSIX filesystem. But this could still confuse
some code that wouldn't be ready to cope with this.

Filter out empty names coming from the client at the top level,
so that the rest doesn't have to care about it. This is done
everywhere we already call is_safe_path_component(), but
in a separate helper since the usual error for empty path
names is ENOENT instead of EINVAL.

6d118c4349 virtiofsd: Add qemu version and copyright info
Option "-V" currently displays the fuse protocol version virtiofsd is
using. For example, I see this.

$ ./virtiofsd -V
"using FUSE kernel interface version 7.33"

People also want to know software version of virtiofsd so that they can
figure out if a certain fix is part of currently running virtiofsd or
not. Eric Ernst ran into this issue.

David Gilbert thinks that it probably is best that we simply carry the
qemu version and display that information given we are part of qemu
tree.

So this patch enhances version information and also adds qemu version
and copyright info. Not sure if copyright information is supposed
to be displayed along with version info. Given qemu-storage-daemon
and other utilities are doing it, so I continued with same pattern.
This is how now output looks like.

$ ./virtiofsd -V
virtiofsd version 5.2.50 (v5.2.0-2357-gcbcf09872a-dirty)
Copyright (c) 2003-2020 Fabrice Bellard and the QEMU Project developers

5bb8327b65 virtiofsd: Release vu_dispatch_lock when stopping queue
QEMU can stop a virtqueue by sending a VHOST_USER_GET_VRING_BASE request
to virtiofsd. As with all other vhost-user protocol messages, the thread
that runs the main event loop in virtiofsd takes the vu_dispatch lock in
write mode. This ensures that no other thread can access virtqueues or
memory tables at the same time.

In the case of VHOST_USER_GET_VRING_BASE, the main thread basically
notifies the queue thread that it should terminate and waits for its
termination:

main()
 virtio_loop()
  vu_dispatch_wrlock()
  vu_dispatch()
   vu_process_message()
    vu_get_vring_base_exec()
     fv_queue_cleanup_thread()
      pthread_join()

Unfortunately, the queue thread ends up calling virtio_send_msg()
at some point, which itself needs to grab the lock:

fv_queue_thread()
 g_list_foreach()
  fv_queue_worker()
   fuse_session_process_buf_int()
    do_release()
     lo_release()
      fuse_reply_err()
       send_reply()
        send_reply_iov()
         fuse_send_reply_iov_nofree()
          fuse_send_msg()
           virtio_send_msg()
            vu_dispatch_rdlock() <-- Deadlock !

Simply have the main thread to release the lock before going to
sleep and take it back afterwards. A very similar patch was already
sent by Vivek Goyal sometime back:

https://listman.redhat.com/archives/virtio-fs/2021-January/msg00073.html

The only difference here is that this done in fv_queue_set_started()
because fv_queue_cleanup_thread() can also be called from virtio_loop()
without the lock being held.
