There are two ways to express an interruption subclass:
- As a bitmask, as used in cr6.
- As a number, as used in the I/O interruption word.
Unfortunately, we have treated to I/O interruption word as if it
contained the bitmask as well, which went unnoticed so far as
- (queued-for-next) kvm made the same mistake, and
- Linux guest kernels don't check the isc value in the I/O interruption
word for subchannel interrupts.

do_io_interrupt() would stop scanning further iscs if it found
an I/O interrupt it could inject. This might cause the pending

The return value of .save_live_pending() is the number of bytes
remaining. This is just an estimate because we do not know how many
blocks will be dirtied by the running guest.
Currently our return value for .save_live_pending() is wrong because it
includes dirty blocks but not in-flight bdrv_aio_readv() requests or
unsent blocks. Crucially, it also doesn't include the bulk phase where
the entire device is transferred - therefore we risk completing block
migration before all blocks have been transferred!
The return value of .save_live_iterate() is the number of bytes
transferred this iteration. Currently we return whether there are bytes
remaining, which is incorrect.
Move the bytes remaining calculation into .save_live_pending() and
really return the number of bytes transferred this iteration in
.save_live_iterate().
Also fix the %ld format specifier which was used for a uint64_t
argument. PRIu64 must be use to avoid warnings on 32-bit hosts.

Linux block devices can be set read-only with "blockdev --setro
<device>". The same thing can be done for LVM volumes using "lvchange
--permission r <volume>". This read-only setting is independent of
device node permissions. Therefore the device can still be opened
O_RDWR but actual writes will fail.
This results in odd behavior for QEMU. bdrv_open() is supposed to fail
if a read-only image is being opened with BDRV_O_RDWR. By not failing
for Linux block devices, the guest boots up but every write produces an
I/O error.
This patch checks whether the block device is read-only so that Linux
block devices behave like regular files.

The incoming migration is processed in a coroutine and uses an fd read
handler to enter the yielded coroutine when data becomes available.
The read handler was set too broadly, so that spurious coroutine entries
were be triggered if other coroutine users yielded (like the block
layer's bdrv_write() function).
Install the fd read only only when yielding for more data to become
available. This prevents spurious coroutine entries which break code
that assumes only a specific set of places can re-enter the coroutine.
This patch fixes crashes in block/raw-posix.c that are triggered with
"migrate -b" when qiov becomes a dangling pointer due to a spurious
coroutine entry that frees qiov early.

1ceef9f273 added handling for cleaning
up multiple queues in qemu_del_nic() for cases where multiqueue is in
use. To determine the number of queues it looks at nic->conf->queues,
then iterates through all the queues to cleanup the associated
NetClientStates. If no queues are found, no NetClientStates are deleted.
However, nic->conf->queues is only set when a peer is created via
-netdev or netdev_add, and is otherwise 0. This causes us to spin in
net_cleanup() if we attempt to shut down qemu before adding a host
device.
Since qemu_new_nic() unconditionally creates at least 1
queue/NetClientState at queue idx 0, make qemu_del_nic() always attempt
to clean it up.

It's OK and expected for visitors to return errors when presented with
the fuzz test's random data. Since the fuzzer doesn't care about
errors, we pass in NULL rather than an Error**. This fixes a bug in
the fuzzer where it was passing the same Error** into each visitor,
with the effect that once one visitor returned an error, each later
visitor would notice that it had been passed in an Error** representing
an already set error, and do nothing.
For the case of visit_type_str() we also need to handle the case where
an error means that the visitor doesn't set our char*. We initialize
the pointer to NULL so we can safely g_free() it regardless of whether
the visitor allocated a string for us or not.
This fixes a problem where this test failed the MacOSX malloc()
consistency checks and might segfault on other platforms [due
to calling free() on an uninitialized pointer variable when
visit_type_str() failed.].
