Few steps allocate new resources, and all of the allocated can be
checked to avoid trying to free an invalid one.
This series includes an already posted patch [1], because it must be applied
on top of that.

When we use BLK_MIG_BLOCK_SIZE in expressions like
block_mig_state.submitted * BLK_MIG_BLOCK_SIZE, this multiplication
is done as 32 bits, because both operands are 32 bits. Coverity
complains about possible overflows because we then accumulate that
into a 64 bit variable.

We are having bunch of issues with killpriv_v2 enabled by default. First
of all it relies on clearing suid/sgid bits as needed by dropping
capability CAP_FSETID. This does not work for remote filesystems like
NFS (and possibly others).
Secondly, we are noticing other issues rel

The latest glibc 2.36 has extended sys/mount.h so that it
defines the FSCONFIG_* enum constants. These are historically
defined in linux/mount.h, and thus if you include both headers
the compiler complains:

This is already handled in op_msa. I'm going to remove it for v4.
It was easier to allow vhost_svq_add to handle the memory. Now that we
will allow qemu to add elements to a SVQ without the guest's knowledge,
it's better to handle it in the caller.

CVQ of net vhost-vdpa devices can be intercepted since the work of [1]. The
virtio-net device model is updated. The migration was blocked because although
the state can be megrated between VMM it was not possible to restore on the
destination NIC.

There is no need to get them by parameter, since they're contained in

Since we're going to allow SVQ to add elements without the guest's

Since QEMU will be able to inject new elements on CVQ to restore the
state, we need not to depend on a VirtQueueElement to know if a new
element has been used by the device or not. Instead of check that, check
if there are new elements only using used idx on vhost_svq_flush.

In addition to the prior TRNG patch from v3, this v4 adds SHA-512
support.
I know, I know, I know -- I fussed around asking if somebody would help
me implement this because it was "oh so hard", and offered to do the
crypto part if someone would do the rest. But then once I had the crypto
part, I w
In order for hosts running inside of TCG to initialize the kernel's
random number generator, we should support the PRNO_TRNG instruction,
backed in the usual way with the qemu_guest_getrandom helper. This is
confirmed working on Linux 5.19.

In order to fully support MSA_EXT_5, we have to also support the SHA-512

short and compact, which is what we're going fo
