c2ab3a6f74 backends/iommufd: Remove check on number of backend users
QOM already has a ref count on objects and it will assert much
earlier, when INT_MAX is reached.

c817e5a377 vfio/migration: Add helper function to set state or reset device
There are several places where failure in setting the device state leads
to a device reset, which is done by setting ERROR as the recover state.

Add a helper function that sets the device state and resets the device
in case of failure. This will make the code cleaner and remove duplicate
comments.

9f734a117c vfio/container: Rename vfio_init_container to vfio_set_iommu
vfio_container_init() and vfio_init_container() names are confusing
especially when we see vfio_init_container() calls vfio_container_init().

vfio_container_init() operates on base container which is consistent
with all routines handling 'VFIOContainerBase *' ops.

vfio_init_container() operates on legacy container and setup IOMMU
context with ioctl(VFIO_SET_IOMMU).

So choose to rename vfio_init_container to vfio_set_iommu to avoid
the confusion.

No functional change intended.

6ba254801f vfio/iommufd: Remove the use of stat() to check file existence
Using stat() before opening a file or a directory can lead to a
time-of-check to time-of-use (TOCTOU) filesystem race, which is
reported by coverity as a Security best practices violations. The
sequence could be replaced by open and fdopendir but it doesn't add
much in this case. Simply use opendir to avoid the race.

f221f641a2 vfio/spapr: Introduce a sPAPR VFIOIOMMU QOM interface
Move vfio_spapr_container_setup() to a VFIOIOMMUClass::setup handler
and convert the sPAPR VFIOIOMMUOps struct to a QOM interface. The
sPAPR QOM interface inherits from the legacy QOM interface because
because both have the same basic needs. The sPAPR interface is then
extended with the handlers specific to the sPAPR IOMMU.

This allows reuse and provides better abstraction of the backends. It
will be useful to avoid compiling the sPAPR IOMMU backend on targets
not supporting it.

fdaa774e67 vfio/container: Introduce a VFIOIOMMU QOM interface
VFIOContainerBase was not introduced as an abstract QOM object because
it felt unnecessary to expose all the IOMMU backends to the QEMU
machine and human interface. However, we can still abstract the IOMMU
backend handlers using a QOM interface class. This provides more
flexibility when referencing the various implementations.

Simply transform the VFIOIOMMUOps struct in an InterfaceClass and do
some initial name replacements. Next changes will start converting
VFIOIOMMUOps.

A CAN sja1000 standard frame filter mask has been computed and applied
incorrectly for standard frames when single Acceptance Filter Mode
(MOD_AFM = 1) has been selected. The problem has not been found

RTOS which uses single filter mode.

e199f7ad4d backends: Simplify host_memory_backend_memory_complete()
Return early if bc->alloc is NULL. De-indent the if() ladder.

Note, this avoids a pointless call to error_propagate() with
errp=NULL at the 'out:' label.

Change trivial when reviewed with 'git-diff --ignore-all-space'.

287fa32324 hw: Simplify accesses to the CPUState::'start-powered-off' property
The 'start-powered-off' property has been added to ARM CPUs in
commit 5de164304a ("arm: Allow secondary KVM CPUs to be booted
via PSCI"), then eventually got generalized to all CPUs in commit
c1b701587e ("target/arm: Move start-powered-off property to generic
CPUState"). Since all CPUs have it, no need to check whether it is
available. Updating this property can't fail, so use &error_abort.
